DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, the cleaning screen with cleaning function of this embodiment includes a fixed frame 1 and an upper hopper 2, a lower chute 3 is fixedly arranged above the fixed frame 1, a cleaning screen 4 parallel to the lower chute 3 is arranged above the lower chute 3, a first spring 5 is fixedly arranged between the bottom of the cleaning screen 4 and the lower chute 3, a vibration motor 6 is fixedly arranged at one end of the right side of the cleaning screen 4, and the cleaning screen 4 includes a first screen body 401 located at the bottom and a second screen body 402 located at the upper position, and the meshes on the first screen body 401 and the second screen body 402 are staggered, and the staggered meshes can allow grain to pass through the cleaning screen 4. An adjusting device 7 for adjusting the position of the second screen body 402 is arranged between the first screen body 401 and the second screen body 402. When the adjusting device 7 adjusts the position of the second screen body 402, the distance of the mesh dislocation on the first screen body 401 and the second screen body 402 changes, thereby allowing the grain, debris, etc. stuck on the mesh to fall.

[0022] Furthermore, the first sieve body 401 and the second sieve body 402 are both U-shaped structures. The U-shaped structures of the first sieve body 401 and the second sieve body 402 can not only prevent grain from falling outside the cleaning sieve 4 during the screening process, but also facilitate the installation of the adjustment device 7.

[0023] Further, the adjusting device 7 includes a second spring 701 and a threaded rod 702, the second spring 701 and the threaded rod 702 are respectively located on both sides of the second sieve body 402, and a rotating handle 8 is provided at one end of the threaded rod 702 away from the second sieve body 402. When the rotating handle 8 is rotated, the rotating handle 8 drives the threaded rod 702 to rotate, and the position of the threaded rod 702 changes, so that the position of the second sieve body 402 changes, and then the size of the mesh misalignment on the first sieve body 401 and the second sieve body 402 changes.

[0024] Further, a feeding plate 9 is obliquely arranged at the lower position on the left side of the cleaning screen 4. The grains etc. passing through the cleaning screen 4 can be guided and fed.

[0025] Working principle: First, adjust the adjusting device 7 according to the size of the screened material, change the mesh offset on the first screen body 401 and the second screen body 402 to a suitable size, and when screening, the material falls onto the cleaning screen 4 through the discharge chute 3, and the vibration generated by the vibration motor 6 acts on the cleaning screen 4, and the material on the cleaning screen 4 is vibrated and screened. After the equipment has been working for a period of time, the offset meshes on the first screen body 401 and the second screen body 402 will jam the material. When the material needs to be cleaned, the size of the mesh offset on the first screen body 401 and the second screen body 402 is adjusted by the adjusting device 7, so that the material stuck on the mesh is discharged, and the mesh is cleaned.

[0026] When the adjusting device 7 is adjusting, the rotating handle 8 is rotated, and the rotating handle 8 drives the threaded rod 702 to rotate, so that the position of the threaded rod 702 changes, so that the position of the second screen body 402 changes, and then the mesh misalignment size on the first screen body 401 and the second screen body 402 changes.
