[0018] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , in the present invention, a self-cleaning drum sieve includes a drum sieve body 1. Support plates 2 are installed on both the left and right sides of the drum sieve body 1. A stabilizing plate 4 is fixedly connected to the bottom end of each support plate 2. The stabilizing plate 4 can be used to enhance the stability of the support plate 2, thereby ensuring the firmness of the drum sieve body 1.

[0021] A motor 3 is installed on the left side of one of the two support plates 2, and the motor 3 is in transmission connection with the drum sieve body 1. The operation of the motor 3 can drive the drum sieve body 1 to rotate.

[0022] A moving plate 7 is arranged above the drum sieve body 1. A group of brush hairs 6 are installed on the bottom surface of the moving plate 7. The diameter of the brush hairs 6 is smaller than the sieve holes of the drum sieve body 1, so that they can be inserted into the sieve holes to dredge.

[0023] A slide groove 19 is opened on the upper surface of the moving plate 7. A slide plate 5 is slidably connected to the inner wall of the slide groove 19. The slide plate 5 can be used to stabilize the position of the moving plate 7 and prevent the moving plate 7 from shifting.

[0024] The bottom end of the skateboard 5 is connected to the upper surface of the support plate 2. On the right side surface of one of the two support plates 2, a motor 13 is installed. The output end of the motor 13 is fixedly connected to a turntable 12. The top of the right side surface of the turntable 12 is rotatably connected to a connecting plate 11. The left side surface of the connecting plate 11 is rotatably connected to a rotating shaft 14. The left end of the rotating shaft 14 is fixedly connected to a lifting plate 10. The top end of the lifting plate 10 is connected to the bottom surface of the moving plate 7. When the motor 13 works, it can drive the turntable 12 to perform a circular motion. The turntable 12 will then pull the connecting plate 11. At the same time, the lifting plate 10 will drive the moving plate 7 to perform a reciprocating motion, and the brush bristles 6 can then complete the dredging of the mesh holes of the drum sieve body 1.

[0025] A sliding hole 9 is formed in the upper surface of the moving plate 7. The inner wall of the sliding hole 9 is slidably connected to a sliding rod 8. The bottom end of the sliding rod 8 is connected to the upper surface of the support plate 2. By using the connection between the sliding rod 8 and the sliding hole 9, the moving plate 7 can be further guided, thus ensuring the stability of the moving plate 7 during movement.

[0026] The top end of the skateboard 5 is fixedly connected to a baffle 17. The baffle 17 can be used to limit the rising height of the moving plate 7.

[0027] A through hole 18 is formed in the upper surface of the baffle 17. The inner wall of the through hole 18 is slidably connected to a support rod 20. The bottom end of the support rod 20 is connected to the upper surface of the moving plate 7. The top end of the support rod 20 is fixedly connected to a retaining ring 15. A spring 16 is sleeved on the outer surface of the support rod 20. By using the elasticity of the spring 16, the retaining ring 15 can be pushed, and the support rod 20 will then apply a certain lifting force to the moving plate 7, thereby preventing the moving plate 7 from falling automatically.

[0028] The working principle of the present utility model is as follows: When it is necessary to clean the drum sieve body 1, start the motor 13 to work. The motor 13 will drive the turntable 12 to rotate. The turntable 12 will drive the connecting plate 11 to perform a circular motion. At the same time, the rotating shaft 14 will drive the moving plate 7 to perform a reciprocating lifting motion. When the moving plate 7 descends, it will drive the brush bristles 6 to insert into the mesh holes of the drum sieve body 1, thereby realizing the dredging of the mesh holes. Then, the drum sieve body 1 can be rotated, and the brush bristles 6 will continue to insert into the mesh holes on the drum sieve body 1, and the comprehensive cleaning and dredging of the drum sieve body 1 can be completed.
