The bulk grain enters the bulk grain transfer bin through the grain leakage net, and then is transported to the bin by the bulk grain conveyor. The manual grain pushing process in the prior art is not only time-consuming and laborious, but also requires the staff to stand on an unstable and easily collapsed grain surface to operate, which is very dangerous and poses a safety hazard.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0022] In the utility model, a bulk grain unloading device for a grain loading vehicle is implemented as follows Figures 1 to 4 As shown: it includes a longitudinal track 14 extending along the front-to-rear direction in the guiding direction for installation at the grain unloading position, item 1 in the figure represents the wall of the grain unloading position, and item 12 represents the ground of the grain unloading position. In this embodiment, the longitudinal track is fixed on the wall, and the longitudinal track includes an upper track 2 and a lower track 3. The upper track 2 and the lower track 3 have track grooves with notches arranged opposite to each other, and the upper track and the lower track are both composed of H-shaped steel.
[0023] The longitudinal track is provided with a moving bracket 6 for guiding movement, and the moving bracket 6 is driven by the first driving mechanism. The specific moving bracket is provided with four track wheels 7 for contacting and rolling with the corresponding track grooves, two of which are upper track wheels arranged at intervals in front and back, and the other two track wheels are lower track wheels arranged at intervals in front and back, and the two lower track wheels are driving wheels 8 connected to the first driving mechanism in transmission, and the first driving mechanism includes a driving wheel motor, which is connected to the corresponding driving wheel in transmission to drive the corresponding driving wheel to rotate.
[0024] The moving bracket is provided with a vertical track whose guiding direction extends in the up-down direction. The vertical track is provided with a lifting bracket 10 for guiding movement. The lifting bracket 10 is driven by a second driving mechanism. The second driving mechanism includes a vertically arranged driving cylinder 17. The driving cylinder 17 is a hydraulic driving cylinder. The upper end of the driving cylinder 17 is connected to the lifting bracket 10, and the lower end of the driving cylinder 17 is connected to the moving bracket 6. When the piston rod of the driving cylinder is extended, the lifting bracket can move upward, and when the piston rod of the driving cylinder is retracted, the lifting bracket can move downward.
[0025] The lifting bracket is provided with a telescopic rod 13 whose axis extends in the left-right direction. The telescopic action of the telescopic rod 13 is driven by the telescopic rod driving mechanism. The end of the telescopic rod away from the lifting bracket is provided with a grain pushing structure for pushing the bulk grain on the grain transport vehicle to the left or right. In this embodiment, the telescopic rod is a hydraulic telescopic rod, which includes at least two telescopic sections that are telescopically matched in sequence in the left-right direction. The grain pushing structure is arranged at the right end of the rightmost telescopic section. The grain pushing structure is a grain pushing plate. The grain pushing plate includes a vertical grain pushing plate 15 arranged vertically. The vertical grain pushing plate has a grain pushing surface facing right. A triangular grain pushing plate bracket 16 is fixed on the left side of the grain pushing plate. The grain pushing plate bracket 16 is used to ensure the structural strength of the vertical grain pushing plate and prevent the vertical grain pushing plate from deforming during use. The hydraulic power of the telescopic rod and the driving cylinder comes from the hydraulic power system. The hydraulic power system includes a hydraulic oil tank arranged on the moving bracket and a pump arranged on the hydraulic oil tank.
[0026] A telescopic rod bracket 11 is arranged on the lower side of the telescopic rod on the lifting bracket, and the leftmost telescopic section is fixed to the upper end of the telescopic rod bracket 11.

When in use, the grain transport vehicle moves to the grain unloading position. At this time, the grain transport vehicle is located on the right side of the bulk grain unloading equipment. The vehicle railing of the grain transport vehicle is lowered, and some bulk grain will be automatically unloaded onto the grain leakage net under the action of its own weight, and the remaining bulk grain needs to be unloaded through the bulk grain unloading equipment. During specific operation, the telescopic sections of the telescopic rod are extended in sequence, and the vertical grain pushing plate pushes the bulk grain on the grain transport vehicle down from left to right. The pushing height of the vertical grain pushing plate can be adjusted by the lifting and lowering adjustment of the lifting bracket, and the front and rear pushing positions of the vertical grain pushing plate can be adjusted by the forward and backward movement adjustment of the moving bracket, so that all the bulk grain on the grain transport vehicle is pushed to the grain leakage net on the ground, realizing unmanned mechanized grain pushing, reducing the labor intensity of the staff, and avoiding the safety hazards caused by manual grain pushing by the staff.
