Embodiment 1

[0043] agricultural machinery sowing

[0044] Insert the connecting rods of the agricultural machinery into the left and right handles or the connecting blocks of the agricultural machinery, and the movement of the agricultural machinery drives the rim body to rotate. When sowing in the forward direction, inside the anti-reverse sowing finger clip type precision seeder, the anti-reverse sowing finger clip structure installed on the rotating frame rotates around the central cam, when the first anti-reverse sowing paddle and the When the protruding side of the central cam touches in the forward direction, the first anti-reversing paddle drives the second anti-reversing paddle to swing counterclockwise with the bolt as the center, that is, the first anti-reversing paddle The one anti-reversal paddle and the second anti-reversal paddle do not move relative to each other, and the second anti-reversal paddle opens the finger clip through the bracket joystick and completes the clampi...

Embodiment 2

[0046] walk-behind sowing

[0047] Insert the handles into the handles on the left and right sides or the connecting blocks of the agricultural machinery, and push the handles to rotate the rim body. When sowing in the forward direction, inside the anti-reverse sowing finger clip precision seeder, the anti-reverse sowing finger clip device installed on the rotating frame rotates around the central cam, and the two anti-reverse sowing paddles do not move relative to each other. And it is lifted up by the center cam, which drives the finger clip joystick to open the finger clip and complete the clamping and picking action. The clamped seeds pass through the seed guide ring and a seed selection ring with a stepped structure is installed to screen out the excess seeds. And enter the seed guide hole through the gap of the seed selection circle, and finally fall into the duckbill to wait for sowing. On the outside of the anti-reverse sowing finger-clip precision seeder, when the du...

Abstract

The invention discloses an anti-reverse-sowing finger-clamping type precision seeder. The seeder comprises a plurality of anti-reverse-sowing finger clamp structures which are uniformly arranged on aframe disc. When seeds in a seed box structure reach the inner part of a fixed seed cover through a seed guide block, the wheel rim body is driven to rotate through a handle or an agricultural machine, the wheel rim body drives a frame disc to rotate, and the anti-reverse-sowing finger clamp structure installed on the frame disc makes contact with the center cam, so that the anti-reverse-sowing finger clamp structure has the effects of clamping seeds in the forward direction and protecting the finger clamp control rod in the reverse direction (reverse sowing). The anti-reverse-sowing finger-clamping type precision seeder provided by the invention has the characteristics of seed saving, uniform seeding and stable row spacing; and particularly, due to the design of a anti-reverse finger-clamping structure, the seeding precision of the precision seeder is more stable, the reliability is greatly improved, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of agricultural seeder machinery, in particular to an anti-reverse sowing finger clip type precision seeder. Background technique [0002] Precision sowing means that crop seeds can be accurately and quantitatively sowed into the soil according to the set row spacing, grain spacing, sowing depth and seed number. The precision seeder has the characteristics of saving seeds, uniform sowing and stable plant spacing, which is convenient for intertillage weeding and field management, and helps to realize agricultural automation and fine management, especially for the increase of crop production in arid and semi-arid areas. [0003] Due to the inconsistent seed size of the existing finger-clip seeders, it is easy to miss sowing, reseeding or even break the ridge, resulting in waste of land and seeds. In addition, because the existing finger-clip seeder is not designed with a reverse sowing protection device, the ...
