Seed lowering device of a hand-push seeder

Abstract

The invention discloses a seed discharge device of a hand-pushed seeder. A seed box is arranged inside a shell and is rotationally connected with the shell; a seed discharge device is mounted at the bottom of the seed box; a seed taking wheel is arranged inside the shell of the seed discharge device; two hinging points of the seed taking wheel are respectively a first hinging point and a second hinging point; a swinging arm is arranged at one end of the seed taking wheel; a first baffle is arranged inside the seed taking wheel; a seed leaking hole is formed in the first baffle; a seed taking hole is formed in the seed taking wheel; a seed discharge hole is formed below the seed taking wheel; the seed discharge hole and the seed leaking hole are communicated with each other; a second baffle covers the lower end surface of the seed taking wheel; when the seed taking wheel is positioned at the first hinging point, the seed taking hole of the seed taking wheel is internally communicated with the seed box; the seed discharge hole in the seed taking wheel is communicated with a duckbilled inlet in the shell; when the seed taking wheel is positioned at the second hinging point, the seed taking hole of the seed taking wheel is communicated with the seed leaking hole, and the seed discharge hole of the seed taking wheel is opposite to the second baffle; a shifting rod is mounted on the side surface of the shell. The seed discharge device of the hand-pushed seeder, which is disclosed by the invention, is capable of seeding small-size seeds, and is reliable to use.

Description

technical field [0001] The invention provides a seed setting device of a hand-push seeder, in particular a seed-setting device of a hand-push seeder for sowing small seeds. Background technique [0002] The bottom of the seed box in the existing hand-push seeder is equipped with a seed-taking device, and the seed-taking wheel of the seed-taking device is evenly arranged with a seed pit along the circumference, and the top of the seed-taking wheel is placed on the bottom of the seed box, and the seeds are placed under the force of gravity. The action falls in the seed pit, and the side of the seed wheel is equipped with a brush that rotates in the opposite direction to the seed wheel. The brush sweeps away the excess seeds around the seed wheel to ensure that there is a seed in the seed pit, and the seed will follow When the seed-taking wheel rotates to the bottom, it falls into the duckbill by its own gravity. The seed-picking device of the above-mentioned structure seeder i...

[0002] The bottom of the seed box in the existing hand-push seeder is equipped with a seed-taking device, and the seed-taking wheel of the seed-taking device is evenly arranged with a seed pit along the circumference, and the top of the seed-taking wheel is placed on the bottom of the seed box, and the seeds are placed under the force of gravity. The action falls in the seed pit, and the side of the seed wheel is equipped with a brush that rotates in the opposite direction to the seed wheel. The brush sweeps away the excess seeds around the seed wheel to ensure that there is a seed in the seed pit, and the seed will follow When the seed-taking wheel rotates to the bottom, it falls into the duckbill by its own gravity. The seed-picking device of the above-mentioned structure seeder is more useful when taking corn seeds and other seeds with large grains and a certain weight, but when sowing Light weight, thin and small seeds such as rapeseed will be stuck at the connection between the seed wheel and the seed box, resulting in waste seeds, and the small seeds will be swept out of the seed pit by the brush, resulting in holes. Or the seeds are adsorbed on the hair brush, and fall into the shell of the seeder with the rotation of the hair brush, causing waste, because the seed-setting device cannot reliably take seeds from small particles, so the hand-pushed seeds of the prior art Smaller seeds such as rapeseed cannot be sown
