Seed screening device for agricultural processing

Abstract

The seed screening device for agricultural processing comprises a support, a screening box body is arranged on the support, a screening box upper cover is arranged on the surface of the screening box body, a feeding port is formed in the surface of one side of the screening box upper cover, a fixing rod is arranged on the side face of the screening box upper cover, and a first conveying pipe is arranged at the top end of the fixing rod; two fixing rings are arranged on the outer side of the fixing rod, two moving rings and a spring are arranged on the outer side of the fixing rod and located between the two fixing rings, the spring is located between the two moving rings, holding rods are arranged on the side faces of the moving rings, and a second connecting rod and a first connecting rod are arranged on the other side faces of the two moving rings correspondingly. A hopper is arranged at the end of the second connecting rod, a cylinder ring is arranged at the bottom of the hopper, and a filter screen is arranged in the cylinder ring. The dumped seeds are filtered through the filter screen, and the filter screen filters out impurities such as large-particle crushed soil, rocks and waste contained in the seeds, so that graded screening of the seeds is facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural screening machinery and equipment, and in particular relates to a seed screening device for agricultural processing. Background technique [0002] The linear vibrating screen uses the vibration of the vibrating motor as the source of vibration power, so that the material is thrown up on the screen and moves forward in a straight line at the same time. The oversize and undersize of different specifications are discharged from their respective outlets. The linear vibrating screen has the advantages of low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, etc. Linear vibrating screens are widely used in the screening of agricultural seeds. [0003] The existing linear vibrating sieve is used in the screening of agricultural seeds. There is a problem that the seeds contain large impurities of crushed soil and st...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a seed screening device for agricultural processing, to solve the problem that the seeds contained in the above-mentioned background technology contain relatively large impurities of crushed soil and stones that enter the inside of the sieve box from the feed port, and the larger impurities are sieved. If it does not fall off, it will increase the degree of wear of the screen
