The moving component 9 starts and drives the moving door 10 to move and open. The first motor 94 drives the threaded rod 93 to rotate and drives the moving block 95 to move. The moving block 95 drives the moving door 10 to move. After the sealed packaging bag is pushed over and passes through the discharge port 8, it is placed on the conveyor belt 3. The conveyor belt 3 drives the packaging bag to be transported.

[0038] When fertilizer enters the packaging bag, dust is generated. The air pump 24 is started to extract the air from the filter box 21, creating a negative pressure inside the filter box 21. The dust enters the filter box 21 through two sets of first conveying pipes 22 and second conveying pipes 23. The dust carried in the air falls onto the filter screen 274. Pulling the second handle 273 moves the mounting frame 271 and simultaneously pulls the locking block 272 out of the locking slot 26, which can clean the dust on the filter screen 274. This effectively collects and treats the dust generated during the bagging process, prevents environmental pollution, and also protects the health of the workers.
