Abstract

The invention belongs to agricultural machinery and discloses a gear-rack driven hole sowing and seed discharging mechanism for a seed discharger with a hole wheel. The mechanism is formed by assembly of a fixing frame, a driving shaft, a driving wheel, a wheel pin, a hole digging piston, a piston pin, a rack, a seed feeding and discharging shaft, a seed feeding and discharging gear, the hole wheel, a cylindrical seed discharger body, a seed inlet barrel, a seed cleaning brush, a seed cleaning knife and a seed transmission pipe. The wall of a hole digging piston barrel is provided with a vertical piston pin operating notch and a vertical rack operating notch, the hole wheel is provided with a hole and an annular groove, and the cylindrical seed discharger body is provided with a seed inlet and a seed outlet. By the driving wheel for driving the hole digging piston and the rack for driving the seed feeding and discharging gear to rotate in a power transmission process, action coordinative consistency of the hole digging piston and the hole wheel is realized, synchronous operations of hole digging and sowing are completed, and high synchronicity of hole digging and sowing, high operation quality and reliability in use are realized.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical hole wheel seed metering device for hole sowing and metering. 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 soil accumulation in the hole forming mechanism, which restricts and limits the new agron...
