Abstract

The invention discloses a seed suction mechanism. According to the seed suction mechanism, a blocking assembly used for blocking communication between an adsorption hole and a negative-pressure adsorption cavity is arranged in the negative-pressure adsorption cavity, the adsorption force generated by negative-pressure adsorption integrally and uniformly acts on a seed-metering disc, and the acting force of contact between the seed-metering disc and the blocking assembly is uniform; and the defects that in the prior art, the seed-metering disc and a sealing strip of the seed suction mechanism are prone to being abraded, the service life is short, and the maintenance cost is high due to the fact that friction force between the seed-metering disc and the sealing strip is large due to local negative pressure are overcome. In addition, the negative pressure does not generate force deviating from a rotating shaft of the seed-metering disc on the seed-metering disc, so that the seed-metering disc and a negative-pressure suction disc can stably rotate on a rotating base, and the seed suction mechanism has the advantages of long service life and low maintenance cost. The invention further discloses a seed-metering device and an air suction type seeding machine. The seed-metering device has the advantages of long service life and low maintenance cost.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an air-suction seeder, a seed metering device and a seed-suction mechanism. Background technique [0002] The seed meter is the core component of the seeder, and its structure and function directly affect the operating efficiency and service life of the seeder. The function of the seed meter is to convert the seeds from groups to individuals, forming a uniform seed flow or a continuous single seed. [0003] The air-suction seed metering device is the most widely used seed metering device in the market, and it is mostly used in high-speed and precision seeders. Its working principle is: a negative pressure is generated in a part of the area on one side of the seeding disc (with a negative pressure chamber), so that the seeds on the other side are adsorbed on the seeding disc and rotate with the seeding disc, and the seeds are in the negative pressure chamber. The ...
