Multi-stage potato classifying and screening device

Abstract

The invention discloses a multi-stage potato classifying and screening device. The multi-stage potato classifying and screening device comprises a cylinder, wherein a plurality of large sieve holes which are uniformly distributed are formed in the side wall of the cylinder; a box body is arranged on the outer side of the cylinder; a plurality of small sieve holes are formed in the bottom end of the box body; the cylinder is connected with a rotating device; a pushing device is arranged on the cylinder; the rotating device comprises a supporting rod; the supporting rod is positioned on the right side of the box body; a motor is arranged at the top end of the supporting rod; the output end of the motor is fixedly connected with a shaft rod; the tail end of the shaft rod extends into the boxbody and is fixedly connected with the cylinder; a supporting plate is arranged on the left side of the box body; a rotating shaft is arranged on the right side wall of the supporting plate; and the tail end of the rotating shaft is rotatably connected to the side wall of the box body. The cylinder and the box body are arranged, the rotating device can drive the cylinder to rotate, and potatoes inthe cylinder are screened, so that small potatoes fall out from the large sieve holes; and the pushing device can push the box body to swing, so that smaller potatoes are screened out from the smallsieve holes, and multi-stage classifying and screening of the potatoes are realized.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a potato multi-level classification and screening device. Background technique [0002] Potato, scientific name potato, is a perennial herbaceous plant belonging to the family Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Potatoes are also called ground eggs, potatoes, potatos, etc., the tubers of Solanaceae plants. Together with wheat, rice, corn, and sorghum, it has become one of the top five crops in the world. Potatoes are native to the Andes in South America. In 2015, the country will launch the potato staple food strategy, and promote the processing of potatoes into staple foods such as steamed buns, noodles, and rice noodles. Potatoes will become rice, wheat, etc. , Another staple food besides corn. [0003] Potatoes need to be sorted after they are recovered from the vegetable fie...
