Abstract

The invention relates to a pneumatic-bucket wheel combined type precise seed-metering device for plot single-seed sowing. The pneumatic-bucket wheel combined type precise seed-metering device comprises a seed-metering device shell, a seed conveying wheel, a pneumatic suction cup, a bucket wheel disc, an outer partition plate, a seed pushing brush, an outer fixing piece, a seed cavity shell, a seed cleaning door, a compression spring, a spring fixing piece, a fan, an air pipe, a seed receiving box, bolts, nuts and set screws. The seed-metering device shell is connected with the seed cavity shell to form a seed-metering space; the bucket wheel disc, the outer partition plate and the air suction cup are sequentially installed on the seed conveying wheel through the set screws, the outer partition plate is located between the bucket wheel disc and the pneumatic suction cup, seed spoons on the bucket wheel disc, seed grooves in the seed conveying wheel and seed discharging holes in the pneumatic suction cup correspond to one another, and seed suction holes are located above the seed spoons; and the seed receiving box is arranged right below a seed cleaning opening of the seed cavity shell and is used for collecting residual seeds. According to the pneumatic-bucket wheel combined type precise seed-metering device for plot single-seed sowing, the seed taking success rate of the seed-metering device is guaranteed, and the quality of plot seed-metering operation is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a pneumatic-spoon wheel combined precision seed metering device for single seed sowing in plots. Background technique [0002] Field breeding experiment is a small-scale experiment for cultivar breeding, which plays a very important role in promoting the stability and development of agricultural production. Existing studies have found that when an excellent crop variety is popularized and applied on a large scale, its yield can increase by 5%-10%. Field breeding experiment is a complex agricultural system engineering, and the mechanization of breeding experiment is conducive to improving work efficiency and reducing labor intensity and cost. Plot seeding operation is an important part of it, which has a significant impact on the accuracy of breeding test results, and its mechanized operation level restricts the development of the breeding industry. [0003] At ...
