Detachable chute seed protecting device

Abstract

The invention discloses a detachable chute seed protecting device, comprising a seed protecting device body, a lightweight ring groove and a chute, wherein the lightweight ring groove and the chute are areas without a material, the lightweight ring groove is arranged at the upper part of the seed protecting device body, and the chute is arranged at the lower part of the seed protecting device body. A seed protecting plane adopted by the device disclosed by the invention has a support effect on seeds in mold holes, and achieves a relatively good seed protecting effect for matching with a seeding roller, and the cross section of the seed protecting plane is arc-shaped or in a shape of a stepped surface; the side wall of the chute has a restraining effect on the seeds in the mold holes and cooperates with the seed protecting plane at the same time to achieve continuous and fixed-point seeding of the seeds; and a chute passage has a guiding effect on the seeds in the mold holes, and provides a stable seed protecting passage for the seeds in the mold holes. The detachable chute seed protecting device improves the seeding precision, is light in mass, difficult in aging and reliable in work, and is suitable for a single-row or centralized seeding apparatus.

Description

[0001] Technical field: [0002] The invention relates to the technical field of agricultural seeding machinery and equipment, and mainly relates to a detachable chute seed protection device. [0003] Background technique: [0004] The seed metering device is the core working part of the seeder, and its seeding performance determines the operating performance of the seeder. The hole wheel type seed metering device has the advantages of simple structure and stable operation. It is a widely used precision seed metering device. Its seed protection devices mainly include fixed plate type, follower belt type and brush type. The fixed plate type seed protection device is mostly used on hole wheel type seed meters for corn and rice. Although the structure is simple and the manufacturing cost is low, the seeds wear the seed protection device seriously, and the seed damage rate is high; the follower belt Type and brush type seed protection devices are mostly used in precision sowing of...

Problems solved by technology

The fixed plate type seed protection device is mostly used on hole wheel type seed meters for corn and rice. Although the structure is simple and the manufacturing cost is low, the seeds wear the seed protection device seriously, and the seed damage rate is high; the follower belt Type and brush type seed protection devices are mostly used in precision sowing of seeds with hard seed coats such as rice, wheat and soybeans. Although they can achieve better seed protection and improve seed damage, they are prone to aging, frequent replacement and The seed protection effect is not good for seeds with small grains and thin seed coats
