Embodiment 2:

The filter mechanism 5 includes a flip plate 501, a filter plate 503 and a water outlet pipe 504. The flip plate 501 is rotatably connected to the middle of the second frame 2. The top and bottom ends of the flip plate 501 are fixedly connected to a receiving plate 502. The filter plate 503 is fixedly arranged at the bottom of the second frame 2. The water outlet pipe 504 is fixedly arranged in the middle of the bottom end of the second frame 2.

A rotating shaft 505 is fixedly provided in the middle of the flip plate 501, and the rotating shaft 505 is rotatably connected to the middle of the second frame 2 through a bearing. A second mounting frame 506 is fixedly connected to the middle of the front of the second frame 2, and a second motor 507 is fixedly provided inside the second mounting frame 506. The transmission shaft of the second motor 507 is fixedly connected to one end of the rotating shaft 505. The second motor 507 is started to provide power for the rotating shaft 505, thereby changing the angle of the flip plate 501.

A fixing frame 508 is fixedly connected to both sides of the middle of the front and the middle of the back of the second frame 2. A through slot 509 is provided on both sides of the middle of the front and the middle of the back of the second frame 2. An electric push rod 510 is fixedly provided on one side of the fixing frame 508. The telescopic rod of the electric push rod 510 passes through the fixing frame 508 and is fixedly installed with an abutment block 511. The abutment block 511 is slidably connected to the through slot 509. The electric push rod 510 is adjusted to drive the abutment block 511 to move. The abutment block 511 moves out of the through slot 509 to support the horizontal flip plate 501.

A cylinder 512 is fixedly provided at the bottom of the back of the second frame 2. The piston rod of the cylinder 512 penetrates the back of the second frame 2 and is fixedly installed with a push plate 513. A dirt removal port 514 is opened at the bottom of the front of the second frame 2. The piston rod of the cylinder 512 drives the push plate 513 to move and push the filtered debris out of the dirt removal port 514.

The bottom of the front side of the second frame 2 is rotatably connected with a baffle 515, which is located on one side of the dirt removal opening 514. The baffle 515 blocks the dirt removal opening 514 to prevent debris from falling out at will;

A guide plate 516 is fixedly provided on the inner wall at the bottom end of the second frame 2, and the guide plate 516 facilitates the drainage of the filtered sewage;

Specifically, first, the debris falls and lands on the receiving plate 502, and then the four electric push rods 510 are adjusted at the same time to drive the abutment block 511 to move, so that the abutment block 511 enters the through groove 509, and then the second motor 507 is started to rotate the rotating shaft 505, so that the flip plate 501 rotates one circle and keeps it horizontal again, and then the electric push rod 510 is adjusted to move the abutment block 511 out of the through groove 509 to support the flip plate 501. During the flipping process, the debris on the receiving plate 502 falls on the filter plate 503 for filtering. After filtering, the cylinder 512 is adjusted so that the piston rod of the cylinder 512 drives the push plate 513 to move, and the filtered debris is pushed out from the dirt removal port 514.

When in use, first start the first motor 404 to rotate one of the transmission rollers 401, and drive the other transmission roller 401 to rotate through the rotary grille 402, so that the rotary grille 402 is circulated and transmitted, the sewage is separated from the debris, and the debris is transported to the second frame 2, and the debris falls and falls on the receiving plate 502, and then the four electric push rods 510 are adjusted at the same time to drive the abutment block 511 to move, so that the abutment block 511 enters the through groove 509, and then the second motor 507 is started to rotate the rotating shaft 505, so that the flip plate 501 rotates one circle, and after it is kept horizontal again, the electric push rod 510 is adjusted to make the abutment block 511 move out of the through groove 509 to support the flip plate 501. During the flipping process, the debris on the receiving plate 502 falls on the filter plate 503 for filtering. During the filtering process, the debris transported by the rotary grille 402 falls on the receiving plate 502, avoiding that excess debris falls directly on the filter plate 503, thereby ensuring the filtering effect;

During filtering, sewage flows out from the outlet pipe 504. After filtering, the cylinder 512 is adjusted so that the piston rod of the cylinder 512 drives the push plate 513 to move until the baffle 515 is pushed, so that the baffle 515 rotates and the dirt removal port 514 opens, thereby pushing the filtered debris out of the dirt removal port 514. The electric push rod 510 and the second motor 507 are adjusted again to perform the next filtering, thereby ensuring the filtering effect and smooth dirt removal.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
