Abstract
Description
Technical Field
[0001] This utility model relates to a grain leveling vehicle used for leveling the grain surface during bulk grain storage. Background Technology
[0002] During the storage process, bulk grain is stored in grain warehouses in the form of grain piles. After the bulk grain is put into the warehouse, it will form a series of grain cone structures. It is necessary to use a grain leveling cart to level the surface of the grain pile so that the surface of the grain pile is a flat structure, which facilitates other operations in bulk grain storage.
[0003] Existing grain leveling carts include a frame equipped with a traveling mechanism, which can be a wheeled or tracked mechanism, etc., and a grain leveling pusher is installed at the front end of the frame. In use, the traveling mechanism moves the frame along the surface of the grain pile, and the grain leveling pusher flattens the surface of the grain pile during the reciprocating movement of the grain leveling cart.
[0004] The problem with the existing grain leveling cart is that the pushing length of the leveling pusher is fixed, making it more suitable for use in relatively spacious areas inside the warehouse. However, when facing a right-angle area formed by adjacent warehouse walls, the existing grain leveling cart is not very convenient to operate. To achieve leveling the grain in this area without any blind spots, the direction of movement of the walking mechanism needs to be adjusted to be parallel to one of the warehouse walls. This requires the grain leveling cart to make large-angle turns on the surface of the grain pile, which is very inconvenient. Utility Model Content
[0005] The purpose of this invention is to provide a grain leveling vehicle that can perform grain leveling operations in the corner area of a vertical warehouse wall.
[0006] To solve the above-mentioned technical problems, the technical solution of the present invention for a grain leveling cart is as follows:
[0007] A grain leveling cart includes a frame with a traveling mechanism. At least one side of the frame is provided with a grain leveling pusher. The grain leveling pusher is connected to the frame via a grain pushing bracket. The grain leveling pusher consists of a left pusher and a right pusher hinged to the grain pushing bracket. The hinge axis of the left and right pushers extends vertically. The frame or the grain pushing bracket is provided with a pusher angle adjustment mechanism for driving the left and right pushers to rotate around their own hinge axis. Under the drive of the pusher angle adjustment mechanism, the left and right pushers have a first grain pushing position and a second grain pushing position. In the first grain pushing position, the included angle between the left and right pushers is greater than the included angle between the left and right pushers in the second grain pushing position. In the second grain pushing position, the left and right pushers have a V-shaped structure.
[0008] Furthermore, in the first grain pushing position state, the included angle between the left and right push plates is 180°.
[0009] Furthermore, the aforementioned grain leveling plates are provided on both the front and rear sides of the frame.
[0010] Furthermore, the walking mechanism is a tracked walking mechanism.
[0011] Furthermore, the bottom of the left and right grain pushing plates is equipped with flat grain teeth.
[0012] Furthermore, the grain pusher is hinged to the frame, and the hinge axis of the grain pusher extends in the left and right direction. A support adjustment cylinder is provided between the frame and the grain pusher for adjusting the pitch angle of the grain pusher.
[0013] Furthermore, the grain pushing bracket includes a vertical support, and the adjacent ends of the left and right push plates are hinged to the vertical support. The push plate angle adjustment mechanism includes an angle adjustment cylinder disposed between the grain pushing bracket and the left and right push plates.
[0014] Furthermore, the piston rod of the angle adjusting cylinder is hinged with a first connecting rod and a second connecting rod arranged in a V-shape. The first connecting rod is hinged to the left push plate, and the second connecting rod is hinged to the right push plate.
[0015] The beneficial effects of this utility model are as follows: In this utility model, the grain leveling pusher is composed of a left pusher and a right pusher that are hinged to the grain pushing bracket. When used in a large space, the pusher angle adjustment mechanism adjusts the left and right pushers to the first grain pushing position with a larger included angle, which can realize a wider grain leveling operation. When encountering a corner area of the wall, the pusher angle adjustment mechanism drives the left and right pushers to rotate around their own hinge axis, and the left and right pushers are in a V-shaped second grain pushing position state, which can directly perform grain leveling operations in the corner area, which is very convenient.

[0025] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.
[0027] An embodiment of this utility model of a grain leveling cart is as follows: Figures 1-7 As shown:
[0028] The vehicle includes a frame 11 with a walking mechanism 6. In this embodiment, the walking mechanism 6 is a tracked walking mechanism, which is existing technology and will not be described in detail here.
[0029] The front and rear sides of the frame are respectively connected to the flat grain push plate 5 via the grain pusher bracket. The grain pusher bracket 2 is hinged to the frame. The hinge axis of the grain pusher bracket 2 extends in the left and right direction. A bracket adjustment cylinder 1 is provided between the frame 11 and the grain pusher bracket 2 to adjust the pitch angle of the grain pusher bracket. When the piston rod of the bracket adjustment cylinder 1 retracts, the corresponding grain pusher bracket 2 can be retracted. When the piston rod of the bracket adjustment cylinder 1 extends, the corresponding grain pusher bracket 2 can be lowered.
[0030] The grain pushing support 2 includes a longitudinal support 7 extending in the front-to-back direction, and a vertical support 8 is provided at the end of the longitudinal support 7. The grain pushing plate is composed of a left pushing plate 9 and a right pushing plate 10 that are hinged to the grain pushing support. The adjacent ends of the left pushing plate 9 and the right pushing plate 10 are hinged to the left and right sides of the vertical support. The hinge axis of the left pushing plate 9 and the right pushing plate 10 extends in the up-down direction.
[0031] The grain pushing support 2 is equipped with a push plate angle adjustment mechanism for driving the left and right push plates to rotate around their own hinge axis. Under the drive of the push plate angle adjustment mechanism, the left and right push plates have a first grain pushing position and a second grain pushing position. In the first grain pushing position, the included angle between the left and right push plates is greater than the included angle between the left and right push plates in the second grain pushing position. In the second grain pushing position, the left and right push plates have a V-shaped structure. The push plate angle adjustment mechanism includes an angle adjustment cylinder 3 disposed between the grain pushing support and the left and right push plates. The axis of the angle adjustment cylinder 3 extends in the front-rear direction. The piston rod of the angle adjustment cylinder 3 is hinged with a first connecting rod 13 and a second connecting rod 14 arranged in a V-shape. The first connecting rod 13 is hinged to the left push plate 9, and the second connecting rod 14 is hinged to the right push plate 10.
[0032] In this embodiment, the included angle between the left push plate 9 and the right push plate 10 is 180° in the first grain pushing position state, and the included angle between the left push plate 9 and the right push plate 10 is 90° in the second grain pushing position state. In other embodiments of this utility model, in the first grain pushing position state, the included angle between the left push plate 9 and the right push plate 10 can also be other angles, such as any value between 120° and 180°; in the second grain pushing position state, the included angle between the left push plate 9 and the right push plate 10 can also be other angles, such as any value between 60° and 90°.
[0033] The bottom of the left and right grain pushing plates is equipped with flat grain teeth 4.
[0034] When in use, when the grain leveling car is not used for grain leveling operations, the piston rod of the support adjusting cylinder retracts, as... Figure 4 As shown, the front and rear grain leveling plates can be retracted; when grain leveling is required, the traveling mechanism moves on the surface of the grain pile, the piston rod of the support adjusting cylinder extends, and the grain leveling plates are lowered, as shown. Figure 3 As shown, this achieves the grain leveling operation. When leveling grain in a spacious area, the piston rod of the angle adjusting cylinder extends, unfolding the left and right push plates to the first grain pushing position, as shown. Figure 6 As shown, at this time, the leveling pusher plate has a large pushing width, which can improve the leveling efficiency; when it encounters the corner of the warehouse wall, the piston rod of the angle adjustment cylinder retracts, and the left and right pusher plates are moved to the second pushing position, as shown. Figure 5 As shown, the grain leveling cart can perform grain leveling operations at the corners of the warehouse walls.
