Bucket wheel type precision seeding seed-metering device for plot breeding

Abstract

The invention discloses a bucket wheel type precision seeding seed-metering device for plot breeding, and belongs to the technical field of agricultural mechanical equipment. The bucket wheel type precision seeding seed-metering device comprises a seeding outer fixing body, a transmission, a bucket wheel disc, a separation disc, a seed-metering disc, a seed protection disc, a seed funnel and a seed clearing port, wherein the seeding outer fixing body comprises a driving cavity and a bucket wheel seed-metering cavity, the transmission is arranged in the driving cavity, the output end of the transmission is provided with a driving shaft, the driving shaft is rotatably arranged in the bucket wheel seed-metering cavity, the seed protection disc is fixedly connected to the driving shaft, the seed-metering disc is fixedly connected to the driving shaft, the bucket wheel disc is arranged on the driving shaft, seed spoons are evenly distributed on the circumference of the circumferential sideedge of the bucket wheel disc at equal intervals, the separation disc is arranged between the bucket wheel disc and the seed-metering disc, and a plurality of groups of seed-metering grooves are distributed in the circumferential side edge of the seed-metering disc. The bucket wheel type precision seeding seed-metering device for plot breeding can automatically clear seeds, avoid seed mixing, conveniently control row spacing and effectively solves the problems of reseeding and miss-seeding.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and specifically refers to a scoop-wheel precision sowing and metering device for plot breeding. Background technique [0002] The seed metering device for plot breeding is mainly a special seed metering device for comparing new varieties and different varieties. The precision of seed selection and distance control for plot breeding is very high, and there are many varieties of seeds. The seeds of different varieties are replaced, and the traditional field sowing operation machinery cannot meet the requirements of community breeding. Our country’s community breeding machinery started late, and the seed metering parts mainly use field corn seed metering devices. There is a lack of development of special seed metering devices. At present, there are some problems in seed picking accuracy and seed replacement efficiency; foreign imported machines have better functions. H...

[0002] The seed metering device for plot breeding is mainly a special seed metering device for comparing new varieties and different varieties. The precision of seed selection and distance control for plot breeding is very high, and there are many varieties of seeds. Different varieties of seeds are replaced, and traditional field sowing machinery cannot meet the requirements of community breeding

Our country’s community breeding machinery started late, and the seed metering parts mainly use field corn seed metering devices. There is a lack of development of special seed metering devices. At present, there are some problems in seed picking accuracy and seed replacement efficiency; foreign imported machines have better functions. However, the purchase and maintenance are expensive, and it is not suitable for the agronomic requirements of our country’s community breeding, and the existing plot breeding seed metering device is inconvenient to clear the seeds. When comparing and sorting multiple groups of varieties, it is very easy to cause mixed seeds of different plots
