Seed taking device for duckbilled seeder

Abstract

The invention discloses a seed taking device for a duckbilled seeder, and belongs to the technical field of seeders. The seed taking device comprises a uniform-quantity seed metering mechanism and a seed taking device side cover; the uniform-quantity seed metering mechanism comprises a seed taking device supporting transmission shaft, a rotary seed conveying structure and a seed taking disc; the seed taking device supporting transmission shaft and a roller are coaxially fixed together, and the seed taking device supporting transmission shaft is rotationally connected with a seeder walking bracket; the rotary seed conveying structure comprises a seed metering cavity shell, a rotary seed conveying disc and a seed conveying cavity seed inlet window; the seed taking disc comprises a seed taking spoon fixing disc and a plurality of seed taking spoons, and the plurality of seed taking spoons are circumferentially arranged on the seed taking spoon fixing disc; the seed taking device side cover is fixedly connected with the seed metering cavity shell to form a closed shell of the seed taking device; a seed metering chamber is formed in a space between seed conveying groove side wall plates and the seed metering cavity shell; and the seed taking spoons and seed conveying grooves are in one-to-one correspondence in position. The seed taking device has the characteristics of being compact in structure, convenient to assemble, good in seeding uniformity and stability and capable of realizing quantitative seeding and the like.

Description

technical field [0001] The invention relates to the technical field of seeders. Background technique [0002] The application publication number is CN108353579A, and the Chinese invention patent published on August 3, 2018 discloses "A Duckbill Seeder". Improvement: During the rotation of the drum, the lever of the duckbill and the bearing wheel collide with each other to realize the opening or closing of the opening and closing rotating plate of the sowing opening, so as to ensure the reliable operation of the opening and closing rotating plate of the sowing opening, so that it is suitable for various soils environment for sowing seeds.

Problems solved by technology

However, during the sowing process of the seed picker, there are still problems of poor sowing uniformity and stability.

At the same time, because the seeds in the seeding box are transmitted to the seed guide tube to generate pressure, the seeds will be blocked in the seed picker, and the seeds cannot be fully supplied, resulting in missed sowing, resulting in the phenomenon of lack of seedlings and broken ridges, causing serious damage to agricultural production. loss
