Crop seed screening device

Abstract

The invention discloses a crop seed screening device. The crop seed screening device comprises a box. The box is erected above a screening pond. A hopper is arranged on the upper portion of the box. One side of the box is provided with a connecting pipe and a lower outlet. The other side of the box is provided with a slag discharging port. An upper screening plate, an upper guiding plate, a lower screening plate and a lower guiding plate are arranged in the box from top to bottom. A baffle is arranged between the lower screening plate and the bottom surface of the box. An upper vibrating motor and a lower vibrating motor are installed on the upper screening plate and the lower screening plate respectively. Both the upper screening plate and the lower screening plate are arranged obliquely. The upper screening plate and the lower screening plate are each provided with a plurality of screening holes. According to the crop seed screening device, through the arrangement of the box and the screening pond, seeds in unqualified sizes are separated in the box by means of a vibrating screen, and then imperfect seeds and husks are separated from intact seeds through the screening pond; the structure is simple, using is convenient, and the seed separation rate is greatly increased; in this way, the screening speed is increased, and the planting success rate of screened seeds is increased.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a crop seed screening device. Background technique [0002] In the planting process, the screening of seeds is one of the very important steps. Traditional seed screening is carried out by manual use of dustpans or sieves, which increases labor and labor intensity, and manual operation makes the screening efficiency low. , Time-consuming, resulting in time-consuming and labor-intensive screening of seeds, increased planting costs, and inconvenient use. Most of the existing seed screening machines simulate manual screening, and use vibration to screen out unsuitable seeds. However, after screening in this way, incomplete particles and large seed shells will still be mixed in the seeds, so that the finished seeds A large number of unqualified seeds are mixed in, which reduces the success rate of planting and brings economic losses to farmers.
