Auxiliary seed selection device for agricultural seeder with classified storage structure

Abstract

The invention discloses an auxiliary seed selection device for agricultural seeders with a classified storage structure, which comprises a casing and a driving motor. The closing mechanism is connected with the side wall of the housing, and the inner wall of the housing is fixedly connected with four equidistant vertically arranged storage cylinders, the upper side of the storage cylinders is connected with a feeding hopper, and the upper end of the feeding hopper passes through the cover plate and Extend upwards. The present invention can drive the box body to shake by arranging the transmission mechanism, the shaking mechanism and the engaging mechanism, and the shaking of the box body drives the fourth spring to stretch, and the wedge-shaped block on the box body can be driven to continue contact with the fourth spring due to the restoring force of the fourth spring. The cams touch each other, so that the box body can shake left and right, so as to achieve the function of screening seeds, three layers of screens, so that seeds of multiple specifications can be screened at one time, and seeds of different specifications can be classified and stored, so that the seed selection to raise efficiency.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an auxiliary seed selection device for agricultural seeders with a classified storage structure. Background technique

[0002] Seeder is a planting machine that takes crop seeds as the sowing object. It is used for a certain type or a certain type of crop. It is often named by the name of the crop type, such as grain drill, corn hole sower, cotton seeder, pasture spreader, etc., seed It is the reproductive system of seed plants, which plays an important role in the continuation of species. Seeds are the most basic and important means of production in agricultural production. The quality of seeds is related to the later growth of crops. Therefore, it is necessary to choose the quality before sowing. Only high seeds can obtain high yields, and the seed selection devices of existing agricultural seeders can only select seeds of one specification at a tim...
