Suction wheel type wide precision seeding device

Abstract

The invention provides a suction wheel type wide-width precision seed distribution device, comprising a seed storage box, a seed metering device and a seed metering tube. The seed metering device is a suction wheel type seed metering device, comprising a box body, a cover, an inner core And the seed metering port, the bottom of the seed metering device is fixed with a stopper, the inner core is cylindrical, the drive shaft passes through the inner core, the outer surface of the inner core is evenly distributed with concave and circular dimples, the The concave and round dimples are distributed in a row of five and a row of six at intervals, and the seeding tube is in the shape of an arc, and the arc angle is 40°≤θ≤50°. When working, the negative pressure is generated by the high-speed fan, and the concave circular socket absorbs the seeds under the action of the suction hole below, rotates with the inner core, and turns to the fixed stop below, the suction hole sucks the seeds. Descending or even disappearing, the seeds leave the concave circular socket under the action of the seed scraper and enter the seeding tube. The seeding tube is arc-shaped and forms a certain angle with the ground, which slows down the landing speed of the seeds and prevents the seeds from bouncing and deviating from the sowing after landing. point to improve seeding accuracy.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding equipment, in particular to a suction wheel type wide-width precision seed distribution device. Background technique [0002] The seeder is a kind of planting machinery used for crop seeding. It is the main machine tool for farmland operations and plays an important role in agricultural production. As a key component of the seeder, the seed distributing device is an important factor that determines the quality and performance of the seeder. The essence of the process of the seed distributing device is to transform the seeds from groups to individuals, uniform seed flow or continuous single seed through the action on the seeds. Its working performance directly affects the working quality of the whole planter. [0003] Traditional seed distribution devices are mainly divided into two categories: mechanical and suction wheel. The suction wheel seed distributing device is more accurate ...

AI Technical Summary

Problems solved by technology

[0004] Although there are many types of seed distribution devices, the seed pipes of most of the seed distribution devices are set vertically on the ground. The seeds fall vertically from the seed distribution device, and the landing speed is too fast, causing the seeds to bounce and deviate from the sowing point, affecting the sowing precision
