Abstract

The invention discloses a seed sowing device combining scoop-type seed extraction and piston hole pricking, and belongs to agricultural machinery. The seed sowing device comprises a cylindrical inner cylinder, a cylindrical outer cylinder, a left end cover, a right end cover, a driving shaft, a seed taking scoop, a seed containing pipe, a seed delivery pipe, a hole pricking piston cylinder, a hole pricking piston, a connecting rod, a connecting rod pin and a piston pin, a seed inlet is formed in a left cover plate, a seed sowing port is formed in the cylindrical outer cylinder, a seed outlet is formed in the cylindrical inner cylinder, and a vertical strip-shaped notch is formed in the hole pricking piston cylinder. According to the seed sowing device, seeds are taken by the aid of a scoop, holes are pricked by the aid of a piston, continuous operations of seed taking, hole pricking and seed sowing are achieved, the seed sowing device is novel, reasonable and simple in structure and good in hole pricking quality and hole pricking and seed sowing synchronism, high in hole sowing quality, reliable to use and less in fault.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical seed metering device for hole sowing operation with spoon type seed picking and piston pricking holes. Background technique [0002] Hole sowing and seeding is a new agronomic planting technology that has emerged in recent years. Because of its high sowing precision, small disturbance to the seedbed soil, and low energy consumption, the application of this technology has attracted people's attention. At present, in order to adapt to and meet the agronomic requirements of hole-pricking and seeding, the hole-sowing seed metering device has been under research and development, and has various structural forms. However, due to structural design flaws, the hole sowing seed metering device still has problems such as low hole quality, poor synchronization between hole pricking and sowing, difficulty in ensuring hole quality, and easy accumulation of soil in the hole forming me...
