Non-circular seed single-grain precision seed-metering device

Abstract

The invention relates to a non-circular seed single-grain precision seed-metering device. The non-circular seed single-grain precision seed-metering device comprises a seed-metering device mounting barrel (1), wherein a seed storing groove (2) is formed in the top of the seed-metering device mounting barrel and a seed feeding nozzle (10) is arranged at the bottom of the seed-metering device mounting barrel; an opening is formed in the part, which is located at the groove bottom in the seed-metering device mounting barrel (1), of the seed storing groove (2); a metering amount adjusting module (5) is arranged at the opening; a seed flow guide tapered platform (6), a molded hole disc (8) and a seed protection and seed feeding disc (9) are sequentially arranged just above the seed feeding nozzle (10) from top to bottom; a seed feeding and seed cleaning module (7) is arranged on the side wall of the seed flow guide tapered platform (6); a transmission shaft (4) sequentially penetrates through the metering amount adjusting module (5), the seed flow guide tapered platform (6), the molded hole disc (8) and the seed protection and seed feeding disc (9) from top to bottom along the axial direction of the seed-metering device mounting barrel (1); and the top of the transmission shaft (4) is connected with a driving wheel (3). The seed-metering device has high single grain rate and small seed loss, is convenient to use and has high adaptability in a sowing non-circular seed process; and the non-circular seed single-grain precision seed metering can be stably and efficiently finished.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a single precision seed metering device for non-round seeds. Especially for the device of single grain precision sowing of agricultural machinery. Background technique [0002] At present, the precision sowing technology is a mechanized planting technology in which a certain number of seeds are planted in holes in the soil according to the agronomic cultivation requirements of the crops. It creates the best conditions for growth, and can save a lot of seeds, reduce labor for thinning, and improve crop yield and quality. It is a cost-saving and efficiency-enhancing engineering technology with remarkable effects. Therefore, modern agriculture requires more and more precision seeding. Especially in recent years, breeding, seed processing, agronomic cultivation and other technologies have been continuously developed and improved, which has greatly improved the germin...
