Abstract

The invention discloses an air-blown seed removing method and device. The air-blown seed removing method comprises the following steps: switching on an air flow source, so that an air flow enters a positive pressure cavity of a seed removing rack from air holes in the back of the seed removing rack, and the air flow passes through a central cavity of a hollow cylindrical drum and is blown out from a central hole of a cylindrical blowing nozzle, the blown-out air flow passes both sides of a suction hole of a rolling barrel of a seed sowing device, rotating to upside, so as to blow superfluous seeds adsorbed by the suction holes back into a seed box, thus achieving seed removal. The air-blown seed removing device adopting the air-blown seed removing method comprises the seed removing rack, the cylindrical blowing nozzle, the hollow cylindrical barrel, and a seal ring. The air-blown seed removing device adopting the air-blown seed removing method use the air flow blown out from a seed removing pipe to blow the superfluous seeds adsorbed on the rolling drum of the seed sowing device back into the seed box, thus achieving seed removal. The device can timely remove the superfluous seeds adsorbed by the suction holes of the seed sowing device, thus improving the single grain rate of the seed sowing device, and realizing seed removal for different crop seeds through changing the strength and direction of the seed removing air flow.

Description

technical field [0001] The invention belongs to the field of sowing machinery, and in particular relates to a seed cleaning method and device for an air-suction drum type precision seed metering device. Background technique [0002] Precision seeding has become an advanced planting method, which has significant advantages such as saving seeds, reducing the workload of thinning, and increasing production and efficiency. At present, the main seeding methods of precision seeding operations mainly include pneumatic type, mechanical type, electromagnetic vibration type, etc. Huang Jianlan, Li Zhiwei, Zuo Yanjun and others successively proposed the air-suction roller precision seed metering device. Because the air-suction roller precision seed metering device has the characteristics of high operating efficiency and strong adaptability to the shape of seeds, etc., it has obtained relatively good results. Wide range of applications. However, the internal pressure of the negative p...
