, Description:FIELD
The present disclosure relates to the field of fluid containing tanks and chassis supporting them.
BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
Agricultural vehicle mounted barrels for storing specific proportions of farm related fluids such as water, fertilizers, herbicides or pesticides are generally mounted on the vehicle and secured with the help of fasteners and brackets. However, the cylindrical configuration of the barrels does not necessarily assure secure locking thereof with the brackets, and are subject to dislocation and subsequent spillage of the fluid stored therein.
There is therefore felt a need for an arrangement which alleviates the aforementioned drawbacks.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment here in satisfies, are as follows:
An object of the present disclosure is to provide a chassis-and-tank arrangement for mounting a tank on the chassis without fasteners.
Another object of the present disclosure is to provide a chassis-and-tank arrangement for mounting a tank on the chassis without fasteners which prevents dislocation of the tank to avoid spillage of the liquid stored therewithin.
Other objects and advantages of the present disclosure will be more apparent from the following description, which is not intended to limit the scope of the present disclosure.
SUMMARY
The present disclosure envisages a chassis-and-tank arrangement for mounting a tank on the chassis without fasteners. The arrangement comprises a chassis defined by a pair of long-members spaced apart from each other, and a pair of cross-members spanning the long-members transversely at an operative rear portion of the chassis at a spaced apart distance from each other to define a nesting location between the long-members and the cross-members. The long-members and the cross-members define walls for the nesting location.
The arrangement further includes a tank defined by a hollow body having an operative top wall, an operative bottom wall, an operative front wall, an operative rear wall, and a pair of operative side walls. The body has a first extension extending from the operative front wall to define a seating area to facilitate attachment of a vehicle seat thereon. A seat is configured to project from the operative bottom wall of the tank. The seat is configured to be seated within the nesting location. The body further has an opening configured on the operative top wall, for filling a fluid in the tank, and an outlet manifold configured on the operative bottom wall to allow passage of the fluid from the tank.
The arrangement further includes a securing means provided on the chassis for securing the tank and preventing its displacement from its operative seated configuration.

DETAILED DESCRIPTION
Embodiments, of the present disclosure, will now be described with reference to the accompanying drawing.
Embodiments are provided so as to thoroughly and fully convey the scope of the present disclosure to the person skilled in the art. Numerous details are set forth, relating to specific components, and methods, to provide a complete understanding of embodiments of the present disclosure. It will be apparent to the person skilled in the art that the details provided in the embodiments should not be construed to limit the scope of the present disclosure. In some embodiments, well known processes, well known apparatus structures, and well known techniques are not described in detail.
The terminology used, in the present disclosure, is only for the purpose of explaining a particular embodiment and such terminology shall not be considered to limit the scope of the present disclosure. As used in the present disclosure, the forms "a,” "an," and "the" may be intended to include the plural forms as well, unless the context clearly suggests otherwise. The terms "comprises," "comprising," “including,” and “having,” are open ended transitional phrases and therefore specify the presence of stated features, elements, modules, units and/or components, but do not forbid the presence or addition of one or more other features, elements, components, and/or groups thereof.
When an element is referred to as being "mounted on" another element, it may be directly or, mounted on the other element.
A chassis-and-tank arrangement (100), of the present disclosure, for mounting a tank (110) on the chassis (130) without fasteners will now be described with reference to Figure 1 through Figure 7. The tank (110) of the present disclosure is configured to carry a fluid therein. The fluid may be water, an insecticide, a herbicide, a fertilizer, a pesticide or any fluid that is needed to be transported from one place to another or for an agricultural purpose.
The arrangement (100) comprises a chassis (130) and a tank. The chassis (130) is defined by a pair of long-members (132) and a pair of cross-members. The pair of long-members (132) is configured to be spaced apart from each other. The pair of cross-members (134) is configured to span the long-members (132) transversely at an operative rear portion of the chassis (130) at a spaced apart distance from each other to define a nesting location (135) between the long-members (132) and the cross-members (134). The long-members (132) and the cross-members (134) define walls for the nesting location (135).
The tank (110) is defined by a generally cuboid polymer hollow body having an operative top wall (111), an operative bottom wall (114), an operative front wall (112), and operative rear wall, and a pair of operative side walls flanking the operative front wall (112) and the operative rear wall. The body is configured to have a first extension integral with the operative front wall (112), and configured to extend from the operative front wall (112) to define a seating area (116) to facilitate attachment of a vehicle seat (117) thereon to allow an operator to sit on the seat. The body further includes a seat (118) projecting from the operative bottom wall (114) of the tank (110). The seat (118) is configured to be seated within the nesting location (135). Moreover, the tank (110) includes an opening (120) configured on the operative top wall (111), and an outlet manifold (122) configured on the operative bottom wall (114), more specifically, on the seat (118). The opening (120) on the operative top wall (111) allows the fluid to be let in the tank (110), while the outlet manifold (122) is configured to allow passage of the fluid from the tank.
The arrangement further includes a securing means provided on the chassis (130) for securing the tank (110) and preventing its displacement from its operative seated configuration on the chassis (130).
In a preferred embodiment, the walls defined by the long members (132) and the cross-members (134) have a box-shaped configuration. The horizontal element of each box-shaped wall allows the seat (118) of the tank (110) to rest thereupon, while the vertical element of each box-shaped wall provides support to the tank (110).
In an embodiment, the tank (110) includes a second pair of extensions integral with the operative front wall (112). Each of the second extensions are configured to extend from the operative front wall (112) on either operative sides of the first extension to define a first clamping area (124) and a second clamping area (126). In another embodiment, the first clamping area (124) and the second clamping area (126) are at an operative higher elevation than the first seating area (116). In yet another embodiment, a groove (125) is configured on either of the first clamping area (124) and the second clamping area (126).
In another embodiment, the securing means includes a locking bracket (140) configured to be seated on the seating area (116). The locking bracket (140) is further configured to be lockingly clamped against operative inner walls of the seating area (116). The configuration of the locking bracket (140) is such that it allows the seat (117) to be mounted thereon, and prevents the movement of the tank in the vertical direction.
In an embodiment, a connecting manifold (123) is configured on the second clamping area (126) to facilitate connection of the tank (110) with an agitator (145). The agitator (145) is configured to periodically mix the fluid stored inside the tank.
