[0002] Chili seeds are the seed part of the chili fruit, usually called chili seeds, and chili seeds are usually used for food seasoning. They can be used to make chili powder, chili oil, chili sauce and various spicy seasonings. In order to meet a better eating experience, during the processing of chili, the sorted chili seeds are usually required to be screened again to ensure the fine screening of the chili seeds. Since chili is irritating, long-term manual contact with chili seeds will cause a burning sensation on the hands. Therefore, a fine screening device is required. At present, when screening chili seeds, a screen mesh in the screening device is used to screen the chili seeds. Screening is performed; since the aperture size of the screen is fixed, and the size of the pepper seeds is relatively large, the larger pepper seeds are easily stuck on the screen, resulting in accumulation on the screen surface. Therefore, a push plate is required to push the pepper seeds accumulated on the screen surface out of the device to complete the fine screening of the pepper seeds; since the pepper seeds accumulated on the screen surface are easily stuck on the screen, some pepper seeds fail to pass through the screen in time, resulting in the push plate pushing out the pepper seeds accumulated on the screen surface, resulting in pepper seeds of different sizes still existing inside the accumulated pepper seeds, affecting the screening effect of the pepper seeds.

A plurality of slot cleaning columns 55 are installed on the top of the support frame 54, and the plurality of slot cleaning columns 55 are respectively inserted into the sieve holes of the screen 14. A positioning frame 52 is installed between the outside of the positioning sleeve 51 and the screening box 1. A connecting column 53 is fixed to the bottom end of the support frame 54, and the connecting column 53 passes through the positioning sleeve 51. A connecting assembly 6 is provided on the connecting column 28 for driving the connecting column 53 to move upward or downward along the inside of the positioning sleeve 51. The connecting assembly 6 includes a connecting disk 61 fixedly sleeved on the outside of the connecting column 28 and a pulley 66 fixed on the end of the connecting column 53 away from the supporting frame 54.

In addition, the rotation of the limiting wheel 67 drives the crank wheel 65 to rotate and drives the pulley 66 to move downward along one side of the positioning frame 52, and then the connecting column 53 moves downward to drive the support frame 54 and the plurality of cleaning columns 55 to move downward, so as to quickly pull out the plurality of cleaning columns 55 inserted in the sieve holes, and continue to move downward until they are reset to each other. With this reciprocating motion, it can cooperate with the sieve holes on the screen 14 to improve the screening efficiency of the pepper seeds.
