Rice seed screening machine thorough in screening

Abstract

The invention discloses a rice seed screening machine thorough in screening. A split charging mechanism, an installing frame, a screening mechanism assembly A and a screening mechanism assembly B areincluded. The split charging mechanism is arranged at the position above the installing frame and comprises a storage barrel, a conical shell, a rotation material guiding pipe, a pipe frame, a discharging pipe and a motor A. The screening mechanism assembly A and the screening mechanism assembly B are the same in structure. The screening mechanism assembly A comprises a box, a dust removal mechanism, a roller screening mechanism and a sieve. The dust removal mechanism comprises a draught fan, a stirring roller, a motor C and an arc screen. The roller screening mechanism comprises a motor B, asupporting frame and a screen drum. According to the rice seed screening machine, through the arrangement of the split charging mechanism, the problems that during material conveying in the prior art,due to excessive one-time material conveying, the screening effect is not good, and when material conveying is stopped for the rice seed screening machine, the work efficiency is influenced are solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a rice seed sieving machine for thorough sieving. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originally produced in China, rice was planted in the Yangtze River Basin of China 7,000 years ago. In order to ensure the quality of rice, the selection of seeds is very important. [0003] The deficiencies that existing technology has: [0004] (1) In the prior art, when feeding materials, too much feeding at one time leads to poor screening effect, and when the feeding is stopped, the work efficiency will be affected; [0005] (2) During the sieving process of the prior art, the foreign matter with light weight and too large volume inside the seed cannot be removed; [0006] (3) The prior art is prone to blockage during the screening process. Contents of the invention [00...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a rice seed screening machine that screens thoroughly, which solves the problem in the prior art that the screening effect is not good due to too much feeding at one time when feeding materials. When it stops feeding, it will affect the work efficiency
