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

Abstract

The invention discloses a seed metering device and a seed sowing device, which are used for sowing two rows in one ridge. The air chamber and the seed chamber, the top of the housing is provided with a seed inlet, and the bottom of the housing is provided with a sorting unit. The sorting unit includes a sorting box facing the seed discharge opening, and a fixed shaft runs across the inside of the sorting box. The interior of the sorting box is divided into two chambers, the left and the right, based on the longitudinal surface of the middle of the sorting box. The fixed shaft is covered with a shaft sleeve that can rotate around the fixed shaft. The baffle plate, the end of the finger can touch the outside of the seeding disc, and the finger drives the baffle to rotate under the drive of the seeding disc; the above-mentioned seed metering device is installed at the bottom of the seeder. The invention separates the seeds through the seeding unit, and can realize precise sowing in one ridge and two rows.

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...
