Seed discharging device and seeding device

Abstract

The invention discloses a seed discharging device and a seeding device. The seed discharging device is used for double-line-in-one-ridge seeding and comprises a shell. A rotatable seed discharging disc is arranged inside the shell and divides the interior of the shell into an air sucking chamber and a seed chamber. A seed inlet is formed in the top of the shell. A seed separating unit is arranged at the bottom of the shell and comprises a seed separating box right opposite to a seed discharging opening, a fixed shaft transversely penetrates through the seed separating box, the interior of the seed separating box is divided into a left cavity and a right cavity with the middle longitudinal face of the seed separating box as the reference, the fixed shaft is sleeved with a shaft sleeve capable of rotating around the fixed shaft, and a baffle capable of shielding an inlet in the upper end of any cavity is fixedly installed on the shaft sleeve. The end of a shifting finger can abut against the outer side of the seed discharging disc, and the shifting finger is driven by the seed discharging disc to push the baffle to rotate. The seed discharging device is installed at the bottom of the seeding device. According to the seed discharging device and the seeding device, seeds are separated through the seed separating unit, and double-line-in-one-ridge accurate seeding can be achieved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery sowing, in particular to a single-ridge double-row air-suction seed metering device. Background technique [0002] At present, it is an important long-term strategic decision of our country to develop high-quality, high-yield, efficient and sustainable food crop production and accelerate the pace of its industrialization to ensure food security supply. Important food crops in my country include rice, wheat, cotton, corn, etc. These food crops are suitable for hole sowing. The production of hole sowing food crops requires planting in rows and holes. Different planting areas and different varieties have great differences in row spacing and hole spacing. The number of seeds per hole has a great influence on the number of effective seedlings in the field, which in turn affects the yield of food crops. The requirements for the number of grains per hole of different food crop varieties are also di...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned seed metering device in the prior art can solve the problem of one ridge and two rows of seed metering, but when the seeds are scraped off and fall into the trouser-shaped seed guide holes, it is easy to cause a variety of seeds to fall at the same time or fail to Accurately discharge into the corresponding seed guide hole, so that the double-row sowing cannot be accurately realized
