Abstract

A gear-driven hole-pricking and seed-discharging mechanism of a mold-hole type seed meter belonging to the field of agricultural machinery. The mechanism is assembled from a fixing frame, a driven shaft, a driving shaft, a driven gear, a driving gear, a mold hole wheel, a cylindrical outer cylinder, a seed inlet cylinder, a seed transportation tube, a hole-pricking piston cylinder, a hole-pricking piston, a seed cleaning brush, a piston pin, a gear pin, a connecting rod and a seed cleaning blade. A mold hole and a seed cleaning blade annular groove are formed in a cylindrical outer surface of the mold hole wheel. A seed inlet and a seed discharge outlet are formed on the wall of the cylindrical outer cylinder. A vertical bar-shaped gap is formed in the wall of the hole-pricking piston cylinder. The driving gear is engaged with the driven gear with transmission ratio being 1. In the mechanism, coordination between the mold hole wheel and the hole-pricking piston is controlled and matched in a gear driving manner, so as to complete the hole-pricking and seeding operation. The mechanism has novel and reasonable structure, has good synchronicity in the hole-pricking and seed-discharging operations, is high in hole sowing quality and has good reliability and less malfunction.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical hole-type seed metering device for piercing holes and metering seeds. 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 mechanism, which restricts and limi...
