Abstract

The invention discloses a wheel type seed-metering device. The device comprises a seeding box and a seed-metering pipe, wherein the lower ends of the seed-metering pipe and the seeding box are in connection; and the wheel type seed-metering device also comprises a baffle plate, a seed-metering wheel and a driving shaft, wherein the lower end of the baffle plate is provided with a seed feeding hole; the seed-metering wheel is arranged inside an hollow cavity formed by one angle of the bottom part of the baffle plate and one angle of the bottom part of the seeding box; the seed-metering wheel and the driving shaft are in connection; the seed-metering pipe is arranged below the seed-metering wheel and is in tangent arrangement with the seed-metering wheel; and the bottom part of the seed feeding hole and the bottom part of the seed-metering wheel are mutually paralleled and leveled. The wheel type seed-metering device provided by the invention has the advantages of simple structure, little damage effect on seeds, low breakage rate, uniform seed metering, and easy cleaning when the seed-metering device is jammed.

Description

Technical field [0001] The invention relates to a seed metering device, more specifically a wheel type seed metering device. Background technique [0002] The seed meter is a part of the seeder, which is used to evenly discharge the seeds in the seeding box. Chinese invention patent ZL200710191906.6 discloses a small seed metering device, which belongs to the technical field of agricultural machinery parts. The top of the shell of the seed metering device is open, and the two sides of the opening respectively extend downwards to gradually approach first and second inclined walls. The second inclined wall is equipped with a flexible brush; the horizontal shaft in the middle of the shell is equipped with a metering wheel, At least one circle of seeding holes are evenly spaced on the outer circumference of the seeding wheel. The seeding holes are formed by a cylindrical shape intersecting the outer circle of the seeding wheel, and have a cavity that can accommodate two seeds of ave...
