[0040] The working principle disclosed by the utility model is as follows.

[0041] (i) Before working, the grains are put into the feeding hopper 103, and then the packaging bag is installed on the plurality of mounting nails 611, and the packaging bag is opened by the mounting nails 611, and then the second motor 502 and the first motor 102 are started at the same time, and the first motor 102 drives the fixed plate 108 to rotate. When the fixed plate 108 rotates until the second leakage hole 109 overlaps with the first leakage hole 106, the grains enter the lower block 107 through the first leakage hole 106 and the second leakage hole 109, and the grains pass through the lower block 107. 7 enters the upper cylinder 401, and the grains fall on the second rotating disk 406. When there are lumps in the grains, the grains rotate under the action of the counterweight block 407 to send the grains mixed with lumps into the partition plate 408 and the cavity of the lower cylinder 402. When there are no lumps in the grains, the second rotating disk 406 reverses to send the grains without lumps into the partition plate 408 and the other cavity of the lower cylinder 402. The grains without lumps fall into the entrance of the transport cage 601 through the third leakage hole 409.

[0042] (ii) When the second motor 502 is started, it drives the rotating disk 504 to rotate, the rotating disk 504 drives the moving block 505 to move, the moving block 505 drives the moving plate 506 to slide back and forth along the first limiting groove 503 through the second limiting groove 507, the moving plate 506 drives the driving rod 508 to move, the driving rod 508 drives the first connecting rod 509 to move, the first connecting rod 509 drives the second connecting rod 510 to rotate around the fixed shaft 511, the fixed shaft 511 drives the third connecting rod 512 to move, the third connecting rod 512 drives the moving block 516 to slide along the limiting block 514 through the driving plate 515, the moving block 516 drives the impact rod 517 to move, and the impact rod 517 impacts the lower tube 402, thereby preventing the grains from clogging the third leakage hole 409.

[0043] (III) The grains falling into the transport cage 601 are conveyed into the conveying pipe 608 through the conveyor belt in the transport cage 601, and then conveyed into the packaging bag through the conveying pipe 608. As the grains in the packaging bag increase, the placing cylinder 610 gradually descends, the mounting nail 611 drives the moving frame 605 to descend, and the moving frame 605 drives the lifting plate 609 to slide along the outer surface of the second rotating rod 603. When the lifting plate 609 moves, it drives the fourth connecting rod 607 to move, and the fourth connecting rod 607 drives the clamping plate 606 to slide along the side hole 61 3, the rectangular protrusion slides, and then the conveying tube 608 is clamped by the clamping plate 606, so that the grains no longer enter the packaging bag, and then the placement cylinder 610 is rotated, and the placement cylinder 610 drives the sliding block 615 to rotate. When the sliding block 615 coincides with the exit hole 616, the placement cylinder 610 is removed, and then the packaging bag is removed, and then the placement cylinder 610 is reinstalled on the second middle plate 614. After the work is completed, the lower cylinder 402 is removed from the upper cylinder 401 and the lumps in the lower cylinder 402 are poured out.
