Abstract

The invention provides a double-suction ring broad-width precision sowing apparatus. The apparatus comprises a seed containing box, a seed discharging device and a seed discharging tube, the seed discharging device comprises a shell, a sealing cover and an inner core, the seed discharging device is a double-suction ring air suction type seed discharging device, the bottom of the seed discharging device is fixedly provided with a hollow baffle block, the seed discharging tube is arc-shaped, and the arc angle theta is not smaller than 40DEG and not greater than 50DEG. When the apparatus works, seeds fall into the seed discharging device from the seed containing box, the inner wall rotates with a driving shaft, the seed discharging device adopts a double-suction ring structure to increase the suction force, the seed containing box is divided into two parts, a negative pressure is generated in the seed discharging device through a high speed fan, seeds adsorbed in recessed round pits 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 fall into a seed outlet under the action of a seed scraper and enter the seed discharging tube, and the seed discharging tube is arc-shaped, has a certain angle to the ground and is not vertical 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 relates to the technical field of agricultural seeding equipment, in particular to a wide-width precision seeding device with double suction rings. Background technique [0002] Seeding device 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. [0003] At present, the sowing devices mainly include mechanical type and air-suction type, and the air-suction type, as the most mature and highest-precision sowing method in the known sowing technology, is more and more valued by the seed meter manufacturers. The development of sowing technology has put forward higher requirements for sowing methods, and precision sowing technology was born, that is, to separate the precise amount of seeds from the seed box, and sow them into the field or hole in the hole according to the determined row spacing and grain spacing. [0004] International...
