Automatic grading and grain sorting device for selenium-enriched rice processing

Abstract

The invention discloses an automatic grading and grain selecting device for selenium-enriched rice processing, which comprises a base, a connecting rod arranged along the generatrix of a conical groove is rotatably connected to the base, a screening ball is fixedly connected to the top end of the connecting rod, the connecting rod and the screening ball perform annular motion, and an outer cover is arranged above the base; the outer cover comprises an arc-shaped screen and a connecting plate, the section of the arc-shaped screen is of a straight notch structure, and the bottom of the arc-shaped screen is fixedly connected with the connecting plate. According to the rice screening device, screening balls are driven through a driving motor, in the rotating process of the screening balls, outward centrifugal force is applied to rice, meanwhile, the screening balls are matched with annular movement of the screening balls, so that the internal rice is in dynamic contact with a screening ball screen, circulating screening of all the internal rice is completed, and a better screening effect can be obtained; the screened rice is thrown to the arc-shaped screen and rolls down along the arc-shaped screen, fine broken rice is screened out, and multi-stage screening is achieved.

Description

technical field [0001] The invention relates to an automatic grading and grain sorting device for selenium-enriched rice processing. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also the most important food in China. The main food of the people of the region. [0003] In the process of rice production and processing, it is often necessary to classify and screen the husked rice according to the size of the grain, so as to better package and sell the rice and obtain the best economic benefits. In the traditional sieving equipment, the sieving is carried out through the vibration of a straight sieve. Since the rice is not smooth, the state of the sieve is different, which will cause the problem of poor rice sieving effect. Contents of the invention [0004] The object ...
