[0029] Principle and advantages of use: By setting up the lifting mechanism 2, the device can play a significant advantage during actual use. Specifically, grain can be added to the interior of the upper hopper 4. At this time, the grain will be assisted by the upper hopper 4 and the discharge hopper 6 at the bottom thereof under the action of gravity. Through the precise guidance of the discharge hopper 6, the grain can be smoothly discharged into the top of the loading plate 25 on the conveyor belt 23. Then, the first motor 24 is started to run. The first motor 24 can drive the conveyor belt 23 to rotate stably inside the mounting frame 22. As the conveyor belt 23 rotates inside the mounting frame 22, it can drive the conveyor belt 23 outward. Each loading plate 25 on the surface performs reciprocating rotation displacement, thereby achieving efficient loading. During the loading process, the cylinder 52 is started to operate. Due to the hinged design of the cylinder 52, the articulated frame 53 and the bottom plate 51, when the cylinder 52 is pushed, the entire articulated frame 53 can be pushed to move up and down in a coordinated manner. In this way, the conveyor belt 23 can be assisted to move up and down, so that the position of the grain can be stably and flexibly adjusted up and down during use. This design enables the entire device to be flexibly adjusted to adapt to the grain loading height during use, greatly improving the convenience of the overall use of the device.

[0030] By setting up the dust removal mechanism 3, the present device performs well in the process of feeding. Specifically, the suction fan 32 can be started to operate. When the suction fan 32 is running, a strong negative pressure suction force can be generated inside the filter box 31. At this time, the negative pressure suction force will act on the suction pipe 34 and the suction main pipe 351. The negative pressure of the suction pipe 34 can act on the inside of the discharge hopper 6. At this time, the dust in the grain inside the discharge hopper 6 can be effectively adsorbed and filtered. During the adsorption and filtration process, the suction bucket 353 at the outer end of the pipe frame 352 at the suction main pipe 351 can assist in suction. At this time, the dust generated during the flipping and falling of the feeding plate 25 can be adsorbed by the suction bucket 353. The adsorbed dust will enter the interior of the filter box 31 and be assisted by the filter frame 331 inside the filter box 31 to filter out the dust. After the dust removal is completed, the fixing screw 334 can be loosened to move it outward. At this time, the fixing screw 334 can be disengaged from the inside of the limiting hole 335, thereby separating the filter screw and the limiting hole 335. In this case, the sealing plate 332 can be removed from the filter box 31, and then the filter frame 331 can be pulled out to facilitate the removal of the filter frame 331 from the interior of the filter box 31, thereby facilitating quick inspection and maintenance of the equipment and also facilitating dust removal. This design can greatly improve the overall convenience of use of the device.
