Abstract

The invention provides a secondary seed suction assisting self-disturbance seed discharge plate for an aspirated-air type seed discharge device. The secondary seed suction assisting self-disturbance seed discharge plate comprises a plate body, and a mounting hole, locating holes, seed charge holes, seed stirring grooves and seed removal grooves are formed in the plate body; the mounting hole is formed in the center of the plate body, and the locating holes are formed in the periphery of the mounting hole; the seed charge holes are evenly distributed in the periphery of the plate body, and one seed stirring groove is correspondingly formed in the inner side of each seed charge hole; the seed removal grooves meshed with seed removal wheels of the seed discharge device are formed in the back face of the plate body, and the positions of the seed removal grooves correspond to the positions of the seed charge holes. The seed discharge plate can disturb static seed piles in the operating process, resistance among the seeds can be reduced, the single seed gets rid of constraint of the seed piles and can be adsorbed on the seed discharge plate easily, the seeds which are not adsorbed can be taken to certain height through the seed stirring grooves to fall off, the charge missing seed holes obtain the opportunity of secondary seed charge, therefore, the seed charge performance of the seed discharge device is effectively improved, and sowing missing and empty holes are avoided.

Description

technical field [0001] The invention relates to a seed metering tray, in particular to a secondary auxiliary seed-suction self-disturbance seed metering tray for an air-suction seed metering device, belonging to the field of agricultural machinery. Background technique [0002] Due to its high speed and precision, the air suction seed meter has become the key development direction of precision seeding technology for large seeds. Seed filling is the first link in the working process of the air suction seed metering device, and it is also the basis of the subsequent links. Its working principle is to use the seed disturbing device to disturb the seeds to the "boiling" state to reduce the inter-species resistance, and then use the airflow to form a pressure difference on both sides of the seed-filling hole on the seed-discharging tray to adsorb the seeds on the seed-discharging tray , the seeds are separated from the densely accumulated population with the rotation of the seed...
