Abstract

The invention belongs to the technical field of rural seeding machinery, and provides a self-cleaning hole wheel type seed metering device for small particle diameter seeds, which includes a main casing, a seed row hole wheel is arranged inside the main casing, and the outer wall of the seed row hole wheel There are several evenly distributed scooping teeth along its circumference, and an inclined cone surface with slopes on both sides is provided between any adjacent two scooping teeth. The seed-discharging hole wheel is provided with a seed pushing assembly engaged with the seed-discharging hole. The seed pushing assembly includes a left seed pushing wheel and a right pushing seed wheel symmetrically arranged with respect to the seed-discharging hole wheel, and a left pushing seed wheel and a right pushing seed wheel. The wheels are all provided with gear teeth along their circumferential direction, and the teeth of the left push seed wheel and the right push seed wheel are respectively meshed with the seed discharge hole inside the seed discharge hole wheel; The damage is small, and the qualified rate of seeding can be effectively improved. At the same time, the invention can effectively prevent the clogging of the mold holes, and avoid missed seeding and broken ridges.

Description

technical field [0001] The invention belongs to the technical field of agricultural seeding machinery, and relates to a seeder, in particular to a self-cleaning hole-wheel-type seed metering device for small-diameter seeds. Background technique [0002] my country is a big country for planting small-sized seed crops. The small-sized seeds refer to seeds with an average particle size of less than 3 mm, mainly including rapeseed, millet, and some vegetables and flower seeds. At the same time, my country is also the world's largest rapeseed producer, with planting area and rapeseed output accounting for about 1 / 3 of the world. More than half of my country's edible vegetable oil comes from rapeseed, and its planting industry has always been an important part of my country's agricultural production. With the development of agricultural machinery, a large number of advanced and reliable planting machinery, especially harvesting machinery and field management machinery, have been w...
