Agricultural crop seed selection and screening device

Abstract

The invention discloses an agricultural crop seed selection and screening device, and relates to the technical field of agricultural instruments. Aiming at the problems that manual selection is mostly adopted for seed screening, time and labor are wasted, the efficiency is low, selected seeds cannot be uniform in particle, and when an existing screening device is used for screening, due to non-uniform and uncontrollable species discharging, the screening effect and efficiency are non-ideal, the following scheme is currently provided. According to the following scheme, side plates are welded to the two ends of a bottom plate, two third rotating shafts are rotationally connected to the left side of the side plate on the right side, a second box body is welded to the top of the bottom plate, a first box body is welded to the right side of the inner wall of the top of the second box body, and the inner wall of the left side of the first box body is rotationally connected with a conveying disc. According to the device, the discharging speed of seeds can be controlled by adding the conveying disc, discharging is uniform, seeds with different sizes can be screened by adding two screens with meshes with different sizes, and the device is convenient to use, high in practicability and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an agricultural crop seed selection and screening device. Background technique [0002] Seeds play a decisive role in the continuation of species and are essential for plant reproduction. Only good seeds can grow good crops. In agricultural production, seed selection often determines the growth of crops in the future, so seed selection is very important. Because seeds The shape, size, color, and surface texture of the seeds vary with different plant species, and the seeds contain impurities, diseases and insect pests, and unfulfilled seeds. Often, they need to be screened before planting to remove unqualified seeds. [0003] At present, most of the seed screening is manual selection or sieve screening, which is time-consuming and labor-intensive, and the screening efficiency is low, and the selected seeds cannot guarantee uniform particles, which is not suitable fo...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the seed screening is manual selection or sieve screening, which is time-consuming and labor-intensive, and the screening efficiency is low, and the selected seeds cannot guarantee uniform particles, which is not suitable for the screening of large batches of seeds in agricultural planting. When screening, due to the uneven and uncontrollable feeding of species, the speed cannot be adjusted according to the actual situation, which makes the screening effect and efficiency unsatisfactory
