Description

Technical Field

[0001] The utility model relates to supporting equipment in bulk grain storage, in particular to a crawler-type grain leveling vehicle. Background Art

[0002] After the bulk grain is stored in the warehouse, the surface of the grain pile needs to be leveled. In order to reduce labor intensity and improve the efficiency of leveling, the existing technology often uses a crawler grain leveler that can walk on the surface of the grain pile to achieve the leveling work of the grain pile surface.

[0003] Existing tracked grain leveling vehicles, such as the "A tracked vehicle walking on the surface of a grain pile" disclosed in Chinese patent CN210191672U, include a frame provided with a tracked walking mechanism, the tracked walking mechanism includes a walking track and a track driving device for driving the walking track to rotate, a grain leveling structure is provided on the rear side of the frame, the grain leveling structure includes a grain leveling rake and a grain leveling plate arranged in the front and rear, and the length of the grain leveling plate extends along the left and right directions.

[0004] During operation, the entire crawler vehicle can move on the surface of the grain pile by utilizing the characteristic that the tracks are not easy to sink. As the crawler vehicle moves from back to front, the grain leveling rake first performs a preliminary raking and leveling of the grain pile surface, and then the front side of the grain leveling plate pushes the grain pile surface level.

[0005] The existing tracked grain leveling vehicle has the following problems: 1. The grain leveling structure is only provided on one side of the tracked vehicle, which is not conducive to the front and rear balance of the entire vehicle structure. More importantly, the grain leveling structure can only level the grain when the tracked vehicle moves in one direction. When the tracked vehicle moves in the opposite direction, the grain leveling structure cannot work, resulting in limited grain leveling efficiency; 2. The grain leveling angle of the grain leveling structure cannot be adjusted, which is not particularly convenient to use when facing relatively complex grain pile surface conditions. Utility Model Content

[0006] The purpose of the utility model is to provide a crawler grain leveling vehicle to solve the technical problem in the prior art that the grain leveling structure is set on one side, which causes the grain leveling vehicle to be able to move the grain in only one direction and affects work efficiency.

[0007] In order to solve the above technical problems, the technical solution of a crawler grain leveling vehicle in the present invention is as follows:

[0008] A crawler grain leveling vehicle comprises a vehicle frame provided with a crawler walking mechanism, the crawler walking mechanism comprises a walking crawler and a crawler driving device for driving the walking crawler to rotate, a front grain leveling structure is provided on the front side of the vehicle frame, a rear grain leveling structure is provided on the rear side of the vehicle frame, the front grain leveling structure comprises a front grain leveling plate extending in a left-right direction, the rear grain leveling structure comprises a rear grain leveling plate extending in a left-right direction, the front side plate surface of the front grain leveling plate and the rear side plate surface of the rear grain leveling plate are used to flatten the surface of the corresponding grain pile, and the front grain leveling structure comprises a front grain leveling plate extending in a left-right direction and a rear side plate surface of the rear grain leveling plate. A front flat grain plate connecting rod is fixed to the rear side of the plate, and the rear end of the front flat grain plate connecting rod is hingedly connected to the front end of the frame through a front hinge structure.

In this embodiment, the vehicle frame includes two frame longitudinal beams extending in the front-to-back direction, with a frame cross beam disposed between the two frame longitudinal beams.

[0029] A front flat grain structure is provided on the front side of the frame, and a rear flat grain structure is provided on the rear side of the frame. The front flat grain structure includes a front flat grain plate 17 whose length extends in the left-right direction, and the rear flat grain structure includes a rear flat grain plate 1 whose length extends in the left-right direction. The front side plate surface of the front flat grain plate and the rear side plate surface of the rear flat grain plate are flat grain surfaces 12 used to flatten the surface of the corresponding grain pile. The front side plate surface of the front flat grain plate is an arc-shaped surface with the notch facing forward; the rear side plate surface of the rear flat grain plate is an arc-shaped surface with the notch facing backward.

[0030] A front flat grain plate connecting rod 15 is fixed to the rear side of the front flat grain plate, and the rear end of the front flat grain plate connecting rod is hingedly connected to the front end of the frame through a front hinge structure. A rear flat grain plate connecting rod 2 is fixed to the front side of the rear flat grain plate, and the front end of the rear flat grain plate connecting rod 2 is hingedly connected to the rear end of the frame through a rear hinge structure. A front driving cylinder 3 for driving the front flat grain plate to rotate around the axis of the front hinge structure is provided between the front end of the frame and the front flat grain plate, and a rear driving cylinder 3 for driving the rear flat grain plate to rotate around the axis of the front hinge structure is provided between the rear end of the frame 6 and the rear flat grain plate.

[0031] In this embodiment, the front drive cylinder 16 and the rear drive cylinder 3 are both hydraulic cylinders, and the pump station supplies oil to the front drive cylinder and the rear drive cylinder.

[0032] The front end of the front drive cylinder is hingedly connected to the rear end of the front flat grain plate, and the rear end of the front drive cylinder 16 is hingedly connected to the front end of the frame 6. When the piston rod of the front drive cylinder retracts, the front flat grain plate swings upward about the axis of the front hinge structure. The rear end of the rear drive cylinder is hingedly connected to the front end of the rear flat grain plate, and the front end of the rear drive cylinder 3 is hingedly connected to the rear end of the frame 6. When the piston rod of the rear drive cylinder retracts, the rear flat grain plate swings upward about the axis of the rear hinge structure. Specifically, there are two front flat grain plate connecting rods 15, which are spaced apart from each other. The rear ends of the two front flat grain plate connecting rods are respectively connected to the front ends of corresponding frame longitudinal beams, and the front drive cylinder is located between the two front flat grain plate connecting rods. There are two rear flat grain plate connecting rods 3, which are spaced apart from each other. The front ends of the two rear flat grain plate connecting rods are respectively connected to the rear ends of corresponding frame longitudinal beams, and the rear drive cylinder 3 is located between the two rear flat grain plate connecting rods 2.

The height of the front side grain leveling plate can also be adjusted as needed. When the crawler grain leveling vehicle moves from front to back along the surface of the grain pile, the piston rod of the front side drive cylinder retracts, as shown in the figure. Figure 6As described above, the front flat grain plate flips up and separates from the grain surface, and the rear flat grain plate can flatten the surface of the grain pile, and the height of the rear flat grain plate can be adjusted as needed.
