A pneumatic-scoop wheel combined precision seed metering device for single-seed sowing in small plots

Abstract

The invention relates to a pneumatic-scoop wheel combined precision seed metering device for single-grain seeding in a plot, comprising a seed metering device housing, a seed wheel, an air suction cup, a spoon wheel disc, an outer baffle, a seed pushing brush, an outer Firmware, seed cavity shell, seed cleaning door, compression spring, spring fixing parts, fan, air pipe, inoculation box, bolts, nuts, set screws; the seed meter shell is connected with the seed cavity shell to form a seed metering space; Described scoop wheel disc, outer baffle and air suction cup are successively installed on the seed wheel through set screws, the outer clapboard is located in the middle of the scoop wheel disc and the air suction cup, the seed spoon on the scoop wheel disc and the seed wheel on the seed wheel. The groove corresponds to the seed discharge hole on the air suction cup, and the seed suction hole is located above the seed scoop; the inoculation box is arranged just below the seed clearing port of the seed cavity shell to collect the remaining seed particles. The invention adopts the combined mode of scooping seeds with a scoop wheel and pneumatically sucking seeds, which ensures the success rate of seed picking by the seed metering device and improves the quality of seed metering operations in the community.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a pneumatic-scoop wheel combined precision seed metering device for single-grain sowing in a plot. Background technique [0002] Field breeding experiments are small-area experiments carried out for variety breeding, which play a very important role in promoting the stability and development of agricultural production. Existing studies have found that a large-scale application of an excellent crop variety can increase the yield by 5% to 10%. Field breeding experiment is a complex agricultural system engineering, and realizing the mechanized operation of breeding experiment is beneficial to improve work efficiency and reduce labor intensity and cost. The sowing operation in the plot is an important part of it, which has a significant impact on the accuracy of the breeding test results, and its mechanized operation level restricts the development of the force bree...
