Pneumatic seed protection type precision concentrated seeding device

Abstract

The invention discloses a pneumatic seed protection type precision concentrated seeding device, including a seed box, a seeding roller assembly and a seed divider provided with a seed discharge plug, a seed guide tube, a shunt tube, a seed clearing mouth, a protection room plate and a pressure nozzle. The seeding roller assembly is installed in the seed divider, the seed box and the seed divider are connected through a connecting plate, the inlet of the shunt tube is located in the seed box, and a seed protective air cushion is arranged between the protection room plate and the seeding roller assembly. The invention adopts the "inverted cone" or "inverted rectangular cone" shaped hole for facilitating seed picking, at the same time when shaped hole carrying seeds passes through the pneumatic seed protection zone, the seeds are not easy to embed into the shaped hole.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding machinery and equipment, in particular to an air pressure seed-protecting precision collector. Background technique [0002] The core component of the sowing machinery is the seed metering device. At present, the precision seed metering devices used at home and abroad are mainly divided into two categories: mechanical type and pneumatic type. The mechanical seed metering device has the advantages of simple structure and low cost, and is widely used in precision sowing of soybeans, rice, wheat and other crops, but it is easy to cause damage to the seeds, thereby reducing the precision and stability of sowing. The air-suction seed metering device has the advantages of good adaptability to seeds, low seed damage rate, and high working reliability. Multi-row sowing is realized by the arrangement and combination of the whole machine. The transmission of the whole machine is complicated an...

The mechanical seed metering device has the advantages of simple structure and low cost, and is widely used in precision sowing of soybeans, rice, wheat and other crops, but it is easy to cause damage to the seeds, thereby reducing the accuracy and stability of sowing

The air-suction seed metering device has the advantages of good adaptability to seeds, low seed damage rate, and high working reliability. Multi-row sowing is achieved by means of arranging and combining the whole machine. The transmission of the whole machine is complicated and the strips are easy to break. At the same time, the weight and manufacturing cost of the machine are increased, and the failure rate and energy consumption of the machine are also increased.
