Efficient agricultural seed screening and impurity-removing device

Abstract

The invention discloses an efficient agricultural seed screening and impurity-removing device which comprises a base, a screening box, a rotary shaft and an oscillating rod. The upper side and the lower side of the rotary shaft are rotationally mounted on a top plate and the base correspondingly. A limiting rod is fixedly mounted on the base, and a movable block is mounted on the limiting rod in asliding mode. A connecting rod is fixedly mounted on the lower left side of the screening box, a push rod is hinged to the connecting rod, and the other end of the push rod is hinged to the movable block. Two first sliding grooves and two second sliding grooves are symmetrically formed in the left side wall and the right side wall of the screening box correspondingly. The left ends and the rightends of a first screening plate and a second screening plate are mounted in the first sliding grooves and the second sliding grooves through sliding blocks in a sliding mode correspondingly. Accordingto the efficient agricultural seed screening and impurity-removing device provided by the invention, the screening plates can move left and right along with the screening box and can also move up anddown in the screening box, meanwhile, a knocking block is utilized for knocking the screening box, the screening efficiency is high, and the screening effect is excellent.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an efficient screening and impurity removal device for agricultural seeds. Background technique [0002] Agriculture is an industry that produces food and industrial raw materials by cultivating animals and plants. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. We use the growth and development laws of animals, plants and other organisms to obtain the approval of various departments through artificial cultivation, collectively referred to as agriculture. Agriculture is the basic product that supports the construction and development of the national economy.

AI Technical Summary

Problems solved by technology

[0003] Before sowing, agricultural seeds need to be sieved to remove the sundries and deflated seeds mixed in the seeds, so as to improve the success rate of sowing; the existing seed sieving devices are often used to sieve seeds, but the sieving efficiency is often low, and the sieving The effect is poor and cannot meet the actual agricultural sowing needs; at the same time, the existing screening device is cumbersome to operate and not suitable for actual use
