The anti-blocking mechanism includes an outer shell 10, which is sleeved on the outside of the rotating shaft 5, and the outer shell 10 is fixedly connected to the chassis 1, and a crankshaft 9 is rotatably installed on one side of the rotating shaft 5 in the outer shell 10. In this example, the anti-blocking mechanism also includes a connecting member 11, and one end of the connecting member 11 is movably connected to the crankshaft 9, and the other end of the connecting member 11 is movably connected to a push rod 12. A support rod 13 is provided between the two push rods 12 on one side of the screening drum 3, and the two ends of the support rod 13 are fixedly connected to the push rods 12 on both sides. A number of knocking heads 14 are provided on one side of the support rod 13, and one end of the knocking head 14 is in contact with the screen 4. The setting of the anti-blocking mechanism can be linked with the rotating shaft 5 to continuously drive the support rod 13 to drive the knocking head 14 to reciprocate left and right, so that the knocking head 14 continuously knocks on the screen 4 to make it vibrate, thereby avoiding it from being blocked and affecting the screening effect. In this example, the fixing mechanism includes a rotating rod 15. Both ends of the screening drum 3 have chambers symmetrically opened in the upper and lower parts. The rotating rod 15 is rotatably installed in the chamber. The outer wall of the rotating rod 15 is provided with a gear three 16. Both sides of the gear three 16 are meshed with racks 17. The opposite outer ends of the two racks 17 are connected to sliders 18. The opposite outer ends of the two sliders 18 are connected to an insertion rod 19. The outer side of the insertion rod 19 is provided with a spring 20. One end of the insertion rod 19 is inserted into the slot opened on the side wall of the screen 4.

[0025] The working principle of the utility model is as follows: when in use, the fertilizer to be screened is placed into the screening drum 3 through the material port, the material port is closed by the baffle 6, and then the motor 2 is started to drive the rotating shaft 5, thereby driving the screening drum 3 to rotate, and cooperating with the screen 4 to perform screening. At the same time, the gear 1 7 on the rotating shaft 5 drives the gear 2 8 engaged therewith to drive the crankshaft 9 to rotate, so that the crankshaft 9 drives the connecting piece 11, so that the connecting piece 11 continuously pushes and pulls the push rod 12 to drive the support rod 13 to move back and forth, so that the support rod 1 3 will drive the knocking head 14 to move synchronously, so that when the knocking head 14 corresponds to the screen 4, the knocking head 14 is in a position of contact with the screen 4, so that the knocking head 14 continuously knocks the screen 4 to vibrate to prevent it from being blocked and affecting the screening and filtering effect of the screen 4; and when the screen 4 needs to be removed for cleaning, maintenance or replacement, the pull handle 21 can be pulled, and the pull handle 21 will cooperate with the limit plate 22 to squeeze the spring 23. When the pull handle 21 drives the plug post 24 out of the socket, the pull handle 21 is rotated to drive the limit plate 2 2, thereby driving the rotating rod 15 to rotate, so that the rotating rod 15 drives the gear three 16 to rotate, and the gear three 16 will drive the meshing racks 17 on both sides to drive the slider 18 and the plug rod 19, so that the two plug rods 19 move inwardly relative to each other, so that the plug rod 19 is separated from the screen 4, and then gradually release the pulling force applied to the handle 21, so that the handle 21 gradually resets under the elastic force of the spring 23, so that the handle 21 drives the plug column 24 to be inserted into the corresponding socket, so as to realize the pull of the handle 21. The limit fixation completes the position limiting of the insertion rod 19, and then the screen 4 can be taken out to complete its disassembly, so that it can be cleaned, maintained or replaced. When installing the screen 4, after installing the screen 4 to the corresponding position, repeat the above steps for disassembling the screen 4, so that the insertion column 24 is moved out of the socket and the pull handle 21 is twisted, thereby driving the insertion rod 19 to reset the movement, so that one end of the insertion rod 19 is inserted into the slot opened on the side wall of the screen 4, completing the limit fixation of the screen 4, easy to use, and more practical.
