Description

TECHNICAL FIELD

[0001] The utility model relates to the related field of bean processing, and specifically relates to a multistage screening device for bean processing. BACKGROUND

[0002] Soybean is an annual herbaceous plant and is the most important bean in the world. It originated in China. Chinese scholars mostly believe that its original habitat is the Yungui Plateau. Many botanists also believe that it is derived from Wusuli soybean, which is native to China. The cultivated soybean planted at present is domesticated from wild soybean through long-term directional selection and improvement. The soybean needs to be screened during processing. Screening is a method for separating particle groups according to the powder properties such as size, specific gravity, electrical properties, and magnetism. The operation of separating mixed materials of different particle sizes into various particle size grades by using a screen with holes is called screening.

[0003] For example, the agricultural soybean seed multistage screening device (Patent No. CN221453335U) includes a base. Two vertical plates are symmetrically fixed to the upper end of the base. Three screening boxes are arranged at equal intervals from top to bottom between the two vertical plates. The two upper screening boxes are slidingly connected with the two vertical plates. The lower screening box is fixedly connected with the two vertical plates. Multiple screening openings are formed in the inner bottom of each of the two upper screening boxes.

[0004] The above device screens soybean seeds of different sizes through three screening boxes. It can also screen out unsatisfied soybeans and some soybean leaves, ensuring the quality of subsequent planting. However, the above device does not have a device for cleaning and discharging the beans, which makes it difficult to clean and discharge the beans during screening, resulting in poor screening effect.

After multiple screenings, the beans can fall onto the upper end of the discharge hopper 13 for guided discharge. Through the observation window 33, the worker can observe the impurities in the coarse screen 32, the middle screen 35 and the fine screen 36 in the multiple groups of screening hoppers 31. When the impurities in the screening hoppers 31 are too much, the plug rod 25 can be pulled to separate the magnetic positive electrode 26 at the rear end of the plug rod 25 from the magnetic negative electrode 27, so that the plug rod 25 is separated from the screening box 21 and the screening hoppers 31, and the rotating block 24 is pushed to rotate and separate from the screening hoppers 31. Pulling the handle at the front end of the screening hopper 31 can remove the impurities in the screening hopper 31.
