DESC:TECHNICAL FIELD
[001] The present invention relates to sugar cane harvesters, and more particularly the present invention relates to a self-propellable sugarcane harvester that tops, cuts, cleans, and loads "whole stalk sugar cane”.

BACKGROUND
[002] Sugarcane is the most important agro-industrial crop which is being cultivated on around 26 million hectares area worldwide. The worldwide production of sugarcane is approximate 2 billion tons with an average of 75 tons per hectors.
[003] At the present, it is required to produce more amounts of sugar per unit area, time, and input, in order to keep pace with population growth while preserving the soil and water resources. Manual sugarcane harvesting is a very labour-intensive and laborious activity. Manual sugarcane harvesting requires approximately about 800-1000 man working hours per hector. Delayed harvesting affects the quality of the sugarcane, yield, juice quality, and sugar recovery. Adopting the appropriate mechanical alternatives not only increases productivity but also increases cost efficiency in the sugarcane production system.
[004] Currently, chopper-type mechanical harvesting is available, which cuts the sugarcane in billets. This type of harvesting accelerates the sugar deterioration because of easy access of bacteria through abrasion, failure points, and in-cut surfaces in chopped billets. The sugar loss due to deterioration is depending on atmospheric temperature, humidity, and time between harvesting and crushing. The harvested billets need to be milled as fast as possible. These all factors lead to reduced sugar yield.
[005] Further, the prior art such as US5463856A, and CN113615389A discloses a whole-stalk harvester. Such an existing whole-stalk harvester has limitations in handling the cane stalk. In the existing whole-stalk sugarcane harvester, the whole-stalk sugarcane collecting device is located at the rear of the harvester. After the leaves are peeled from the harvested sugarcane, they are transported and thrown into the cane gathering device. Because the length, size, and shape of the harvested sugarcane stems vary widely, the thrown sugarcane stems are uneven in the cane gathering device. After a certain number of stems are collected, they need to be unloaded in piles to other transfer vehicles or placed on the ground. Since the unloaded sugarcane stems are uneven, it will cause great inconvenience to the later bundling and loading, and usually needs to be sorted manually again. This requires a lot of labour work for collecting and then bundling or loading vehicles.
[006] Accordingly, there is a need for a self-propelled whole stalk sugarcane harvester that tops, cuts, cleans, and loads the whole sugarcane.

OBJECTS OF THE INVENTION
[007] The principal object of the present disclosure is to provide a sugarcane harvester for harvesting the whole stalks of sugarcane.
[008] Another object of the present disclosure is to crop, cut, clean, and load whole sugarcane into the sugarcane collecting device.
[009] Yet another object of the present disclosure is to save the cane from rapid bio-deterioration and its associated sucrose losses by harvesting it in the whole stalk.
[0010] Yet another object of the present disclosure is to reduce the losses due to deterioration depending on the atmospheric temperature, humidity, and time between harvesting and crushing because of the number of chopped pieces of cane.
[0011] Yet another object of the present disclosure is to eliminate the labour work of picking the whole stalk cane from the ground and loading the whole stalk direct into the trailer.
[0012] Yet another object of the present disclosure is to provide a loading mechanism capable of conveying the whole stalk sugarcane and reducing the amount of time and energy to handle the whole stalk cane.

Further the front-drive wheels (4) may be provided with steerability to enable navigation for the harvester (100). The steerability of the wheels of the harvester 100 may be controlled by a steering wheel (5), provided in the driver cabin (2). The driver cabin (2) may be mounted fairly at a height, near a first side of the harvester (100). The driver cabin (2) may be further configured to accommodates a plurality of controls (not shown). The plurality of controls may be provided to control various assemblies mounted on the harvester (100) to perform various operations. The driver cabin (2) may further include a chamber (19) and a prime mover (22). The prime mover (22) may be mounted within the chamber (19). The prime mover (22) may be configured to provide power to all pumps; provide control and deliver hydro-static energy to the topping assembly (6), the crop divider assembly, the cutting and lifting assembly, the feeding assembly, the cleaning assembly, the air extraction assembly (18), and the conveying and loading assembly.
[0031] The topping assembly (6) may be configured to sever the leafy tops of the sugar cane as the harvester (100) drives along a row of sugar cane to be harvested. The topping assembly (6) may further include a topper frame (31), an upper lifting frame (32), a lower lifting frame (7), a hydraulic ram (8), a center drum (58), and a pair of collecting discs (59). The topper frame (31) may be operably pivoted about a transverse axis of the front ends of the upper lifting frame (32) and lower lifting frame (7). The upper lifting frame (32) and the lower lifting frame (7) may be provided one above the other. The rear of the upper lifting frame (32) and the lower lifting frame (7) may be pivoted about the transverse axis of the upper front of the main frame (1). Further, the topper frame (31) may be arranged on the mainframe (1) using the lifting frames (32, 7) so the topping cutter may be raised or lowered in parallelism by the hydraulic rams (8) connected between the front of the mainframe (1) and the lower lifting frame (7). The center drum (8) includes cutters and a vertical plate.
[0032] As the harvester (100) drives along a row of sugar cane to be harvested, the sugar cane tops are received between the pair of collecting discs (59), where the cutters are rotated on the center drum (58) in either direction. The sugar cane tops are severed thereby and are guided by the vertical plate located on the center drum (58) to be thrown to one side of the harvester (100). A hydraulic motor is being operated in either direction so the tops are to be thrown to the side, which is already cleared of cane.
[0033] The crop divider assembly includes at least two spaced crop divider arms (35). The two spaced crop divider arms (35) extend forwardly from the sides of the front of the mainframe (1), to which their lower rear parts are hinged about a common transverse axis at a joint (36). The upright sides of each crop divider arm forwardly form a triangle, and its top surface is inclined forwardly and downwardly to, a point called a shoe (21). The shoe tends to penetrate the soil and be driven under fallen cane. Each of these arms has a rotary crop divider (9, 20). The rotary crop divider (9, 20) is a cylinder having a helical thread (40) secured thereon, which is wound in a specific direction. Further, the rotary crop dividers (9, 20) are being driven by hydraulic motors (not shown). The rotary crop dividers (9, 20) of each side are rotated in opposite directions. The internal crop dividers (9) guide the cane of the cutting row, towards the center and the outer crop dividers (20) separate the other row canes towards the unharvested area.
[0034] The topped cane stalks received between the crop divider arms after being straightened by the rotary crop dividers (9, 20) are pushed forwardly by the upper parts of the threads (40) of the rotary crop dividers (9, 20).
[0035] The cutting and lifting assembly includes a pair of counter-rotating rotary base cutters (10), a primary knockdown roller (11), and a vaned transverse rotary feeder (12). The primary knockdown roller (11) is mounted on the front of the mainframe (1) which helps the threads (40) of the rotary crop dividers (9, 20) in pushing the topped can stalk forwardly. These stalks are cut at or near the ground level by the pair of counter-rotating rotary base cutters (10) mounted below the front of the mainframe (1). Further, each of the counter-rotating rotary base cutters (10) is a disc having a plurality of radiating blades, and a co-axial feed drum (41) secured there above. The butt ends of the severed stalks are urged rearwardly by the vaned transverse rotary feeder (12) below the bottom of the knockdown roller 11, and by the counter-rotating base cutters (10) and the feed drums (41). Further, the vaned transverse rotary feeder (12) is a finned roller. The butt lift roller (13) facilitates the stalks to be carried from the butt ends first and extends it in the transverse direction through the feeding and cleaning assembly.
[0036] The feeding assembly comprises a series of transverse vaned upper feeding rollers (14) and a series of transverse vaned lower feeding rollers (15). The upper and lower feeding rollers (14, 15) are driven by hydraulic motors. Further, the upper and lower feeding rollers (14, 15) are arranged vertically opposite to each other between the left and right-side plates directly to the mainframe (1) in the conveying portion thereof at predetermined intervals in the front-rear direction. In the upper feeding roller (14), a rotary shaft (60) is inserted and fixed at an axial center position of a cylindrical body (61) and a plate (62) of the mainframe (1). The outer side of the upper feeding roller (14) is corrugated by a contour shape vane at an outer periphery of the cylindrical body (61) radially arranged at every predetermined angle.
[0037] The lower feeding roller (15) is fixed on a rotary shaft (63) at a predetermined interval on the plate (62) of the mainframe (1). The outer side of the lower feeding roller (15) is corrugated at an outer periphery of the cylindrical body (64) radially arranged at a predetermined angle. Thus, by rotating the upper feeding roller (14) and the lower feeding roller (15) in opposite directions of each other, the sugar cane stalk is passed through between the upper feeding roller (14) and the lower feeding roller (15) and transported backward. The upper and lower feeding rollers (14, 15) further provide primary cleaning to the sugarcane stalk.
[0038] In an exemplary configuration, the sugarcane cut by the base cutter (10) is transported backward by the butt lift roller (13), in a way that the ends first to the feed drum (41) in a sideways lying posture. At this time, as the stem amount increases, the upper feeding roller (14) swings up and down about a pivot shaft (65) by the arm (66) according to the amount. In this way, it is possible to convey the sugarcane backward without clogging and damaging the stalks. The arrangement of all the upper feeding rollers (14) and lower feeding rollers (15) is in such a way that the distance and angle of all the rollers are accessible easily for serviceability.
[0039] The cleaning assembly inclines upwardly towards the rear end of the whole stalk cane ejected from the upper and lower feeding rollers (14, 15). The cleaning assembly has at least two cleaning rollers (16, 17). The cleaning rollers (16, 17) are rotating leafy drums. Further, the cleaning rollers (16, 17) include a rubber strip (39) and a cylindrical body (67). The rubber strip (39) is corrugated on a periphery of the cylindrical body (67) at a predetermined angle. Further, the rubber strip (39) is configured to strip off the matter from the sugarcane surface. The driving mechanism of the pair of cleaning rollers (16, 17) is the same as feeding rollers (14, 15).
[0040] The upper cleaning roller (16) bears downward by its weight. The upper cleaning roller (16) is properly adjusted in a way that it does not touch the bottom cleaning rollers (17), although they can move upward according to the cane load. The cleaning rollers (16, 17) are rotating at a higher velocity than the velocity of the feeding rollers (14, 15) by which the cane is conveyed in tension at the average speed of all the rollers in contact with the cane, the slip is greater at the ends of the stalk, hence the work of friction is greater at the ends of the cane.
[0041] The cane stalks mixed with the trash are conveyed from the upper portion of the air extraction assembly (18). The whole stalk cane, while passing through the cleaning rollers (16, 17) is acted on by a strong sucking flow of air from the air extraction assembly (18), where extraneous leaves and dirt are removed from the stream of whole stalk cane and clean cane fall onto an elevator (26). The air extraction assembly (18) includes a fan (42), a trash discharge (43), a fan shaft (44), a top wall (45), a tubular frame (46), a tubular fan housing (47), a hydraulic motor (48), and an air duct (49). The fan (42) and the air duct (49) are provided to suck air from existing whole stalk canes. The fan shaft (44) is fixed on the top walls (45) by the tubular frames (46) and extends vertically towards the cane outlet portion. The tubular fan housing (47) extends outwardly at the bottom of the fan shaft (44). The axial flow fan (42) is mounted on fan housing (47) on the fan shaft (44). The hydraulic motor (48) is connected to one end of the fan shaft (44) and configured to drive the axial flow fan (42) to pull air through the lower portion of the chamber into the tubular fan housings (47) and to force air through apertures. The trash discharge (43) is provided on the upper portion of the cleaning chamber to direct air from the fan (42) and entrained trash out of the air extraction assembly (18). Additionally, the axial flow fan (42) has a circular hub (33) and at least three fan blades (34). The blades (34) are mounted equally spaced on the circular hub (33). Ejections are guided through a deflector (30).
[0042] The cleaned whole stalk cane passes out from the lower portion of the air extraction assembly (18) and discharges into the elevator (26) in a container (28). The cleaned cane can load directly in a special trailer called infielder through the conveying and loading assembly. In an exemplary embodiment, the conveying and loading assembly is an elevator and rotating platform system. The elevator and rotating platform are equipped with a harvester in the rear area.
[0043] The rotating platform (53) consists of at least two frames, a fixed frame (50), and a movable frame. The fixed frame (50) is equipped with a movable slew (24) which is connected with the mainframe (1) through a pin shaft and at least two hydraulic cylinders (29) by which the whole unit can rotate both sides within predetermine angle. The movable frame is fixed with fix frame through a pin shaft-housing and rack pinion and a hydraulic cylinder (52) by which the movable frame can rotate 180°. Further, the movable frame has a slew bearing mechanism (55) for better stability.
