“FLOATING ROLLER AND SET OF FLOATING ROLLERS FOR A FARMING
MACHINE AND HARVESTING MACHINE FOR TALL AND STALKY PLANTS”
FIELD OF THE INVENTION
[001] The present invention refers, in general, to a new floating
roller particularly developed to be used in farming machines, such as those
intended for harvesting tall and stalky plants, as is the case of sugarcane and
sweet sorghum. Also, the present invention addresses a set of floating rollers
designed to be installed in a farming machine, such as a cane and sorghum
harvester.
[002] The present invention also refers to a new machine for
harvesting tall and stalky plants which incorporates the set of rollers formed by
the new floating rollers in order to promote increased productivity in sugarcane
and sorghum harvests.
BACKGROUND OF THE INVENTION
[003] According to the state of the art, there are numerous models
of farming machinery and equipment designed to promote increased productivity
in the harvests of various types of vegetable crops, for example, harvesters of
grain, forage crops and, also, harvesting machines of so-called tall and stalky
plants, as is the case of sugarcane and sorghum.
[004] These harvesting machines for tall and stalky plants are
designed and developed to provide the harvesting of this specific type of crop,
since their intrinsic characteristics require particular conditions for suitable
processing thereof, from the cutting of plants to the transfer to the transshipments and/or skips.
[005] Basically, as should be appreciated by the persons skilled in
the art, this model of farming machine intended for the harvesting and processing
of tall and stalky plants comprises a chassis that sustains a series of floating
rollers and chippers responsible for driving and chopping the cane into billets,
Page 1 of 18
which are transferred to the trans-shipments and/or skips by way of an elevator
set.
[006] Particularly in relation to floating rollers, and as is generally
known in the art, it is noted that they are basically formed by a supporting cylinder
with fins installed and spaced radially on its periphery, its ends being endowed,
internally, with bearings responsible for receiving at least a drive shaft that is
associated to a motor fixed to a support, and at the opposite end a pivot that is
also supported by a free-mode support, that is, allowing the rotation of the
supporting cylinder according to the actuation of the drive shaft. Although
functional, this type of construction reveals certain drawbacks generated by the
supports of the drive shafts and pivot comprise a relatively smaller diameter than
the supporting cylinder and, for this reason, ends up forming a gap between the
supports and the edges of the supporting cylinder.
[007] Therefore, considering that these floating rollers are
responsible for driving and moving a relatively large volume of harvested material,
bringing together a huge amount of debris and dust, these gaps formed between
the supports and the supporting cylinder allow for the entry of debris, dirt and
mineral and plant residues into the region of the supporting cylinder where the
bearings, bushings, drive shafts, pivot, and gearwork are installed and, due to the
assembly arrangement of these floating rollers, it becomes virtually impossible to
clean these parts without the withdrawal and disassembly of these rollers.
Therefore, these residues end up accumulating in this region and, as a result,
end up causing premature wear, in addition to requiring the stoppage of the
farming machine for cleaning and maintenance which, as persons skilled in the
art will appreciate, are procedures that require working time that, ultimately, could
affect and impact on the productivity and efficiency of the harvests in general.
[008] In summary, it is noted that the state of the art lacks solutions
and alternatives for the construction and assembly of floating rollers of farming
Page 2 of 18
machines capable of preventing the entry and accumulation of debris, dirt and
mineral and plant residues in their interior and, more specifically, in the region
where the mechanisms responsible for rotating these rollers are installed, such
that the types of floating rollers currently known cannot prevent this wear and
compromise the components and mechanisms installed inside said supporting
cylinder.
[009] Therefore, although they are functional to this day, it has
been found that the sets of floating rollers known and available in the state of the
art lack a practical and functional solution that eliminates, or minimally reduces
or simplifies, the need for premature maintenance of farming machines and, more
particularly, that are capable of increasing the useful life of the mechanisms and
components responsible for the rotation of these rollers. It is thus important to
emphasize that these are, among others, the objectives and solutions that are
sought to be achieved by the development of the present invention.
DESCRIPTION OF THE INVENTION
[010] Therefore, according to the above, the objective of the
present invention is to provide a new floating roller to be used in farming
machines, particularly those intended for harvesting tall and stalky plants, this
floating roller being designed and developed to obtain a practical and functional
solution to the problems, limitations and drawbacks revealed by the floating
rollers known in the state of the art.
[011] More particularly, it is one of the objectives of the present
invention to provide a new floating roller for farming machines that comprises
technical, constructive and functional characteristics capable of preventing the
entrance of debris, dirt and mineral and plant residues in the regions where they
the mechanisms responsible for rotating these rollers are installed and,
accordingly, achieve a considerable increase in the useful life of these
mechanisms and, as a result, reduce the need for maintenance of the floating
Page 3 of 18
assembly and also the downtime of the machine.
[012] It is also one of the objectives of the present invention to
provide a floating set developed to be installed in a harvesting machine of tall and
stalky plants, such as sugarcane and sorghum harvesters.
[013] Yet another objective of the present invention is to provide a
harvesting machine, particularly intended for the harvesting of tall and stalky
plants, such as sugarcane and sorghum, which comprises a chassis whose
intermediate portion is endowed with a set of floating rollers, of which at least one
of them is as referenced above.
[014] Therefore, in order to obtain the technical and functional
effects summarized above, among others, the present invention refers to a new
floating roller which is formed by a supporting cylinder whose outer surface has
a plurality of fins fixed and spaced radially to each other, and inside has support
bases disposed in a receded manner and near to their edges which are arranged
to mount the respective assembly sets responsible for installing the floating roller
next to the chassis of the farming machine, and said edges of the supporting
cylinder comprise an arrangement where sealing elements are disposed,
interacting superficially with said assembly sets.
[015] According to particular embodiments of the present
invention, said assembly sets are arranged for the installation of a pivot axle or a
drive shaft associated to a motor source. In the case of the pivot axle assembly,
the assembly set is formed by a bushing, in which a bearing is laid that supports
said pivot axle whose end is mounted and anchored to the support base of the
supporting cylinder. In the case of the drive shaft assembly, the assembly set is
formed by a support, within which the motor source is installed and whose power
output is associated to the drive shaft whose end is mounted on a pinion provided
with a toothed face that interacts with the toothed face of a flange that is anchored
to the support base of the supporting cylinder.
Page 4 of 18
[016] According to an embodiment of the present invention, said
edges of the supporting cylinder comprise a T-shaped arrangement which shapes
a support surface for the sealing element which projects towards the bearings
and support of the respective assembly sets.
[017] Additionally, the floating roller, according to another
embodiment of the present invention, comprises at least a motor source installed
on one of said edges of the supporting cylinder, and, according to possible
embodiments of invention, this motor source can be a hydraulic or electric motor.
[018] The present invention also addresses a new set of floating
rollers that comprises at least a lower floating roller and an upper floating roller,
which are installed in the intermediate portion of the chassis of a farming
machine, particularly downstream of a base cutter set, and at least one of these
floating rollers of the set of floating rollers is arranged and mounted as defined
above.
[019] Additionally, and as commented on above, the present
invention also refers to a harvesting machine of tall and stalky plants that
comprises a chassis within which there is a processing trajectory formed by a set
of floating rollers that is formed by at least a lower floating roller and at least an
upper floating roller, one of said floating rollers being a roller that comprises the
characteristics indicated above.
[020] According to possible embodiments of the present invention,
said harvesting machine is arranged to carry out the harvest of sugarcane and/or
sweet sorghum.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[022] The invention will now be described in relation to its particular
embodiments, making reference to accompanying drawings. Said figures are
schematic, and their dimensions and/or proportions may not correspond to reality,
since the aim thereof is to describe the invention in a didactic way. Furthermore,
certain known and common constructive details may have been omitted for clarity
and brevity of the following description. The reference numbers used are
repeated throughout the drawings to identify identical or similar parts. Any terms
used such as "above", "below", "front", "back", "right", "left" etc. and variants
thereof should be interpreted according to the guidance given in Figure 1.
[023] The terms used herein such as harvester, picker, harvesting
machine and variations thereof are used indistinctly to indicate a farming machine
intended for harvesting a vegetable crop and, in the case of this description, the
harvesting of tall and stalky plants, such as sugarcane, energy cane, sorghum
etc.
[024] With respect to the drawings, Figure 1 illustrates a side view
of an embodiment of a farming machine 10 according to aspects known in the
state of the art. As shown, the machine 10 is arranged as a sugarcane harvester.
However, in other embodiments, this machine 10 may correspond to any suitable
agricultural harvester model known in the state of the art.
[025] Still with respect to Figure 1, the machine 10 includes a
Page 6 of 18
chassis 12, a pair of front wheels 14, a pair of rear wheels 16, and an operator
cab 18. The machine 10 may also include a primary power source (for example,
a motor mounted on the chassis 12) that powers one or both pairs of wheels 14,
16 through a transmission (not shown). Alternatively, the machine 10 can be a
harvester driven on tracks and therefore may include tracks driven by the motor
mechanism in place of the illustrated wheels 14, 16. The motor mechanism may
also drive a hydraulic fluid pump (not shown) arranged to generate pressurized
hydraulic fluid to drive various hydraulic components of the machine 10, including
wheels or tracks.
[026] Additionally, the machine 10 may include various
components to cut, process, clean and unload sugarcane as the sugarcane is
harvested from an agricultural field 20. For example, the machine 10 may include
a tip cutter set 22 positioned at its front end to intercept the sugarcane as the
machine 10 moves in the forward direction, as indicated by the "X" arrow in Figure
1. As shown, the tip cutter set 22 may include both a gathering disc 24 and a
cutter disc 26. The gathering disc 24 may be arranged to gather sugarcane
stalks, so that the cutter disc 26 may be used to cut the tip of each stalk.
Generally, the height of the tip cutter set 22 may be adjustable by means of a pair
of hydraulically erected and lowered arms 28 as desired by the operator.
[027] Additionally, the harvester 10 may include a line divider 30
that extends up and back from the field 20. In general, the line divider 30 may
include two spiral feed rollers 32, also known as "lollipop". Each feed roller 32
may include a 34 ground shoe, as its lower end assists the line divider 30
separating the stalks of sugarcane for harvest. Additionally, as shown in Figure
1, the harvester 10 may include a toppling roller 36 positioned near the front
wheels 14 and a roller with projections 38 positioned behind the toppling roller
36. As the toppling roller 36 is rotated, the stalks of sugarcane harvested are
toppled while the line divider 30 gathers the stalks from the agricultural field 20
Page 7 of 18
towards the inside of the machine 10. Additionally, as shown in Figure 1, the
roller with projections 38 may include a plurality of fins 40 intermittently
assembled that aid in forcing the stalks of sugarcane down. As the roller 38 is
rotated during harvest, the stalks of sugarcane toppled by the toppling roller 36
are sorted and subsequently toppled by the roller 38 as the machine 10 continues
to be moved forward in relation to the field 20.
[028] Still with reference to Figure 1, the machine 10 may also
include a base cutter set 42 positioned behind the roller 38. As is generally
understood, the base cutter set 42 may include blades (not shown) to cut the
stalks of sugarcane as the cane is harvested. The blades, located on the
periphery of the assembly 42, can be rotated by a hydraulic motor (not shown)
driven by the hydraulic system of the machine. Additionally, in several
embodiments, the blades can be angled down to cut the base of the sugarcane
as the cane is toppled by the roller 38.
[029] Additionally, as shown in Figure 1, the machine 10 may
include a set of one or more floating rollers 44 located downstream of the base
cutter set 42 to move the cut stalks of sugarcane from the base cutter set 42
along the processing trajectory. As shown in Figure 1, the set of floating rollers
44 may include a plurality of lower rollers 46 and a plurality of upper rollers 48.
As the sugarcane is conveyed across the set of floating rollers 44, waste (for
example, stones, dirt and/or the like) can also be conveyed or dropped through
the lower rollers 46 onto the field 20.
[030] Additionally, as can be seen in Figure 1, the machine 10 may
include a chopper set 50 located at the downstream end of the set of floating
rollers 44 (for example, adjacent to the rearmost lower and upper rollers 46, 48).
In general, the chopper set 50 can be used to cut or chop the harvested
sugarcane stalks into pieces or "fragments" 51 smaller which may, for example,
measure 15.24 centimeters (six (6) inches), also called billets. Fragments 51 can
Page 8 of 18
then be driven towards an elevator set 52 of the machine 10 to be collected on
an external receiver or storage device (not shown), for example, the transshipments and skips.
[031] As is generally understood, pieces of waste 53 (for example,
dust, dirt, leaves, etc.) sorted from the sugarcane fragments 51 can be expelled
from the machine 10 through a primary extractor 54, which is located behind the
chopper set 50 and is oriented to direct the waste 53 out of the machine 10.
Additionally, a fan 56 can be mounted on the primary extractor 54 to generate a
suction force or vacuum sufficient to capture the residues 53 and force these
residues 53 through the primary extractor 54. The waste 53 is then directed
outwards and usually in the opposite direction of the machine 10 by means of an
output of the primary extractor 54. The fragments sorted 51 and heavier than the
residues 53 being expelled by the extractor 54, can then fall to the elevator set
52.
[032] According to this specification, the elevator set 52 should be
understood as comprising, in general, an elevator housing structure 58 and an
elevator 60 that extends within said elevator housing structure 58 between a
lower proximal end 62 and an upper distal end 64. The lower proximal end 62
being fixed to the machine 10 and the upper distal end 64 having an opening 82
for discharge of the collected material.
[033] In additional or alternative embodiments, the elevator 60 may
include a chain or conveyor belt 66 and a plurality of paddles or protrusions 68
coupled or spaced evenly on the chain 66. The protrusions 68 can be arranged
to secure the sugarcane fragments 51 in the elevator 60 as the fragments 51 are
raised up to the top portion 70 of the elevator 60. Additionally, the elevator 60
may include lower and upper sprockets 72, 74 positioned around the proximal
and distal ends 62, 64, respectively. As shown in Figure 1, an elevator motor 76
can be coupled to one of the sprockets (for example, the upper sprocket 74) to
Page 9 of 18
drive the chain 66, thus allowing the chain 66 and protrusions 68 to travel in an
endless cycle between the proximal and distal ends 62, 64 of the elevator 60.
[034] Additionally, pieces of waste 53 (for example, dust, dirt,
leaves, etc.) sorted from the sugarcane fragments 51 can be expelled from the
machine 10 via a secondary extractor 78 coupled to the rear end of the elevator
housing structure 58. As shown in Figure 1, the secondary extractor 78 may be
situated adjacent to the distal end 64 of the elevator 60 and can be oriented to
direct the waste 53 out of the machine 10. Additionally, a fan 80 can be mounted
on the secondary extractor 78 to generate a suction force or vacuum sufficient to
extract the waste 53 and force this waste 53 through the secondary extractor 78.
The sorted fragments 51, heavier than the residues 53 expelled through the
extractor 78, can then fall from the distal end 64 of the elevator 60. Typically, the
fragments 51 can fall through a discharge opening 82 of the elevator set 52 into
an external storage device (not shown), such as a car, a trans-shipment, a skip
etc.
[035] During operation, the machine 10 is driven throughout the
farm field 20 to harvest sugarcane or any other tall and stalky plant. Once the
height of the tip cutter 22 is adjusted (if used) by means of the arms 28, the
gathering disc 24 in the tip cutter set 22 can work in such a way as to gather the
sugarcane tips as the machine 10 proceeds through the field 20, while the cutter
disc 26 cuts the leafy tips of the sugarcane stalks to dump them along both sides
of the machine 10. As stalks enter line divider 30, the shoes 34 can arrange the
operation width to determine the amount of sugarcane entering the throat of the
machine 10, either fixed or adjustable. The lollipops 32 then gather the stalks at
the machine entrance to allow the toppling roller 36 to curve the stalks down
together with the action of the feed roller 38. Once the stalks are positioned at
an angle as shown in Figure 1, the base cutter set 42 can then cut the base of
the stalks from the field 20. The cut stalks are then directed to the set of floating
Page 10 of 18
rollers 44.
[036] The cut sugarcane stalks are conveyed backwards by
floating rollers 46, 48 compressing the stalks and harvested matter. At the
downstream end of the set of floating rollers 44, the chopper set 50 cuts or chops
the compressed sugarcane stalks into pieces or fragments 51. Waste 53
conveyed (for example, dust, dirt, leaves, etc.) sorted from sugarcane fragments
51 is then extracted through primary extractor 54 using suction created by the fan
56. The sorted/washed fragments 51 then fall to the elevator set 52 and travel
upwards by means of the elevator 60 from its proximal end 62 to the distal end
64. During normal operation, once the fragments 51 reach the distal end 64 of
the elevator 60, the fragments 51 fall through the discharge opening 82 to an
external storage device. Similar to the primary extractor 54, waste is blown out
of machine 10 through the secondary extractor 78 with the aid of the extractor
fan 80.
[037] A harvesting machine 10, as described above, may be, for
example, a machine known in the state of the art, such as the sugarcane
harvester produced by CNH Industrial N.V. and commercialized under the Case
IH trademark.
[038] Therefore, based on the above, and with reference now to
the other drawings, it is noted that the floating roller 46, 48, according to the
present invention, is formed by a supporting cylinder 100 whose outer surface
has a plurality of fins 101 fixed and spaced radially from each other to assist in
the conduction of the harvested material. Further, the aforementioned supporting
cylinder 100 comprises support bases 102 arranged in a receded manner and
close to its edges 103 which are arranged to mount the respective assembly sets
104 responsible for installing the floating roller on to the chassis 12 of the farming
machine 10, and said edges 103 of the supporting cylinder 100 comprise an
arrangement where sealing elements 105 are arranged, which somehow interact
Page 11 of 18
superficially with said assembly sets 104 and, accordingly, prevent the passage
of debris, dirt and mineral and plant residues in the region (S) where the
mechanisms responsible for the rotation of said rollers are installed.
[039] Usually, this supporting cylinder 100 is usually made of a
metal material, such as steel, and has a hollow arrangement for weight reduction
purposes. However, the body may assume other arrangements and also be
made of various materials, considering that such aspects do not reflect or directly
influence the definition of the present invention per se.
[040] According to particular embodiments of the present
invention, said assembly sets 104 can be arranged for the installation of the pivot
axle 106 or, also, for the assembly of the drive shaft 107 associated to the motor
source 108. In the case of assembly of the pivot axle 106, the assembly set 104
can be formed by a bushing 106a, in which a bearing 106b is arranged to support
the pivot axle 106 and allow the free rotational movement of the supporting
cylinder 100, and the end of said pivot axle 106 is mounted and anchored to said
support base 102 of the supporting cylinder 100. In the case of assembly of the
drive shaft 107, said assembly set 104 may be formed by a support 107a, within
which the motor source 108 is installed and whose power output is associated to
the drive shaft 107, and the end of said drive shaft 107 is mounted on a pinion
107b endowed with a toothed face that interacts with a toothed face of a flange
107c that is anchored to said support base 102 of the supporting cylinder 100.
[041] According to a possible embodiment of assembly of the
present invention, said support bases 102 are welded inside the supporting
cylinder 100 and, even more particularly, said pivot axle 106 is previously welded
on the support base 102 to then assemble the assembly formed by the support
base 102 and the pivot axle 106 inside of said supporting cylinder 100.
[042] Therefore, as persons skilled in the art will appreciate, these
sealing elements 105 which are fixed on the respective edges 103 of the
Page 12 of 18
supporting cylinder 100 come into superficial contact with the bushing 106a in the
case of the layout and assembly of the pivot axle 106, or with the support 107a
in the case of the assembly of the drive shaft 107 together with its motor source
108, whereby protecting the region (S) where the bearings, bushings, drive shafts
and pivot, gearwork etc. are installed which are moving mechanical elements
whose service life can be drastically reduced due to contact with debris.
[043] In a particular assembly of the present invention, where the
aforementioned floating roller 46, 48 is mounted on a floating structure, such as
a movable arm, the assembly set 104 may comprise floating arms and, in this
case, the sealing elements 105 that are fixed on the respective edges 103 of the
supporting cylinder 100 are in superficial contact with these floating arms
whereby to prevent the entry of debris, dirt and mineral and plant residues into
the region (S) where the mechanisms responsible for the rotation of said floating
roller are installed.
[044] According to an embodiment of the present invention, said
edges 103 of the supporting cylinder 100 comprise a T-shaped arrangement, so
as to shape a support surface to the sealing element 105, which, in turn, projects
toward said bearings 106a and support 107a of the respective assembly sets
104.
[045] As persons skilled in the art will appreciate, the floating roller
46, 48, according to the present invention may comprise different assembly
arrangements, either in relation to the assembly structure on the chassis 12 of
the farming machine 10, or in relation to the arrangement of the motor source 108
at one or both ends of said supporting cylinder 100, as well as in the arrangement
of a roller without motor drive, where there is only assembly of the pivot axle 106
at both ends of the supporting cylinder 100. Logically, such arrangements may
vary according to the interests of the manufacturers, as well as machine designs
and models.
Page 13 of 18
[046] Further, according to another embodiment of the present
invention, said motor source 108 may be a hydraulic or electric motor, or may be
connected through a transmission, or by any appropriate means capable of
providing the rotation of these rollers at a desired rotational speed.
[047] The present invention also addresses a new set of floating
rollers 44 designed and developed to be applied in a farming machine, for
example of the harvesters of tall and stalky plants type, and this assembly
comprises at least a lower floating roller 46 and an upper floating roller 48, which
are installed in the intermediate portion of the chassis 12 of the machine 10,
downstream of the base cutter set 42, and at least one of said floating rollers 46,
48 from the set of floating rollers 44 is arranged and mounted like the floating
roller defined above.
[048] Additionally, and as commented on above, the present
invention also refers to a harvesting machine of tall and stalky plants that
comprises a chassis 12 within which there is a processing trajectory formed by a
set of floating rollers 44, which is formed by lower 46 and upper 48 floating rollers,
and at least one of these floating rollers 46, 48 is arranged according to the
characteristics of the invention defined above, such that said supporting cylinder
100 comprises ends whose edges 103 house sealing elements 105.
[049] According to possible embodiments of the present invention,
said harvesting machine of tall and stalky plants is designed and developed to
harvest sugarcane and/or sweet sorghum.
[050] Lastly, in view of all the above, it is worth mentioning that the
purpose of this description is solely to present and define in an exemplifying way
embodiments of the floating roller, the set of floating rollers and the harvesting
machine, according to the objects of the present invention. Therefore, as persons
skilled in the art will appreciate, various modifications and combinations of
elements and equivalent details are possible without straying from the scope of
