The threaded sleeve 9 is a hollow structure. The slide rod 10 is slidably connected to the inside of the threaded sleeve 9, and the right side of the slide rod 10 extends to the outside of the threaded sleeve 9. The push plate 11 is slidably connected to the inner wall of the fixed box 5, and the left side of the push plate 11 is slidably connected to the right side of the slide rod 10. The push rod 13 is rotatably connected to the rear side of the push plate 11 through a rotating shaft, and the rear side of the push rod 13 is rotatably connected to the front side of the fixed block 17 located above through a rotating shaft. The connecting rod 15 is fixedly connected to the front side of the threaded sleeve 9 by welding, and the connecting plate 16 is fixedly connected to the bottom of the connecting rod 15 by welding, and the bottom of the fixed block 17 located below is fixedly connected to the top of the connecting plate 16 by welding.

[0032] By means of the above mechanism: the fixed box 5 is conveniently driven to rotate through the rotating shaft 4 so that the filter screen 6 rotates, and the threaded sleeve 9 can be driven to move through the rotation of the threaded rod 8, thereby driving the sliding rod 10 and the connecting rod 15 to move. When the sliding rod 10 moves, it will drive the sliding shaft to move. At this time, the sliding shaft slides along the direction of the slide groove and pushes the push plate 11 to move right. When the push plate 11 moves, it will push the push rod 13. At this time, the push rod 13 moves and pushes the fixed block 17 located above to move upward. At the same time, the connecting rod 15 drives the connecting plate 16 to move downward, and the fixed block 17 located below is driven downward by the connecting plate 16. The connecting block 7 is conveniently fixed or unlocked by the fixed block 17, so as to install or remove the filter screen 6. Through the cooperation of the threaded rod 8 and the control mechanism, it is convenient to drive the fixed block 17 to move so as to fix or unlock the filter screen 6, thereby facilitating the installation or removal of the filter screen 6, and preventing the filter screen 6 from being damaged and affecting the cleaning effect of the waste.

[0033] In the utility model, the inner wall of the fixed box 5 is fixedly connected with a limiting rod 12 by welding, and the limiting rod 12 penetrates the push plate 11. The limiting rod 12 can limit the push plate 11 so that the push plate 11 can only slide left and right.

[0034] In the utility model, a slide groove is provided on the inner wall of the fixed box 5, and a slide shaft is fixedly connected to the rear side of the slide rod 10 by welding. The outer wall of the slide shaft is slidably connected to the inner wall of the slide groove. The slide shaft is conveniently guided by the slide groove so that the slide shaft and the slide rod 10 can move obliquely.

[0035] In the utility model, the inner wall of the fixed box 5 is fixedly connected to the limit frame by welding, and the left side of the fixed block 17 located above is slidably connected to the inner wall of the limit frame. The limit frame is used to conveniently limit the fixed block 17 located above, so that the fixed block 17 located above can move up and down stably.

[0036] In the utility model, the bottom of the limit frame is fixedly connected with a spring 14 by welding, and the top of the upper fixed block 17 is fixedly connected with the bottom of the spring 14 by welding. The elastic force of the spring 14 facilitates the downward movement and reset of the upper fixed block 17.

[0037] Working principle: In actual use, when the filter screen 6 needs to be disassembled and replaced, the threaded rod 8 is rotated. At this time, the threaded rod 8 moves and drives the threaded sleeve 9 connected by the thread to move. When the threaded sleeve 9 moves, it will drive the sliding rod 10 and the connecting rod 15 to move. When the sliding rod 10 moves, it will drive the sliding shaft to move. At this time, the sliding shaft slides along the direction of the slide groove and pushes the push plate 11 to move right. When the push plate 11 moves, it pushes the push rod 13. At this time, the push rod 13 moves and pushes the fixed block 17 located above. At this time, the fixed block 17 located above moves up and compresses the spring 14. At the same time, the connecting rod 15 drives the connecting plate 16 to move downward, and drives the fixed block 17 located below to move downward through the connecting plate 16. At this time, the two fixed blocks 17 move to the side away from each other. The filter screen 6 is then removed and replaced after the filter screen 6 is disengaged from the fixing groove. The connecting block 7 is unlocked and the filter screen 6 can be removed and replaced. The connecting block 7 of the new filter screen 6 is inserted into the fixing box 5 and the fixing groove is aligned with the fixing block 17. At this time, the threaded rod 8 is rotated in the opposite direction. When the threaded rod 8 moves, the threaded sleeve 9 can be driven to reset. The sliding rod 10 and the connecting rod 15 are driven to reset through the threaded sleeve 9. The connecting rod 15 drives the connecting plate 16 and the fixing block 17 located below to move upward. At the same time, the sliding rod 10 pulls the push plate 11 to move left. At this time, the spring 14 loses its restriction and pushes the fixing block 17 located above to move downward. The two fixing blocks 17 move to the side close to each other and engage with the fixing groove to fix the connecting block 7 so that the filter screen 6 is fixed, thereby achieving the effect of installing or removing and replacing the filter screen 6.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
