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

Abstract

The invention provides a suction wheel type broad-width precious speed distribution apparatus. The apparatus comprises a seed containing box, a seed discharging device and a seed discharging tube, the seed discharging device is a suction wheel type seed discharging device and comprises a box body, a sealing cover, an inner core and a seed discharging opening, the bottom of the seed discharging device is fixedly provided with a baffle block, the inner core is cylindrical in shape, a driving shaft traverses through the inner core, recessed round pits are uniformly distributed on the external surface of the inner core, the recessed round pits are distributed in a five-in-line and six-in-line interval manner, the seed discharging tube is arc-shaped, and the arc angle is not smaller than 40DEG and not greater than 50DEG. When the apparatus works, a negative pressure is generated in the seed discharging device through a high speed fan, seeds are adsorbed in recessed round pits under the action of below air suction holes and rotate with the inner core, the suction force to the seeds decreases and even disappears when the seeds rotate to the fixed hollow baffle block under the seed discharging device, the seeds depart from the recessed round pits under the action of a seed scraper and enter the seed discharging tube, and the seed discharging tube is arc-shaped and has a certain angle to the ground, so the falling speed of the seeds is reduced, deviation from sowing points due to bouncing after seed falling to the ground is avoided, and the sowing precision is improved.

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 ...
