Reversible pull rod press cake type hole sowing device

Abstract

The invention relates to the technical field of agricultural sowing machines, in particular to a reversible pull rod press cake type hole sowing device. The reversible pull rod press cake type hole sowing device comprises a seed cabin cover body, a central shaft, a left pressing disk, a right pressing ring, a frame disk body, a central cam, a reversible feed fetching device and a hole sowing device assembly capable of rotating, wherein the seed cabin cover body comprises a seed cover side plate and a seed cover ring body, and the outer edge of the seed cover side plate and the right end of theseed cover ring body are connected into a whole. The reversible pull rod press cake type hole sowing device has a reasonable and compact structure and is convenient to use. When the hole sowing device assembly forwards rotates, the central cam of the reversible feed fetching device can push a stirring and rotating sheet and a seat rotation sheet to rotate, and therefore, a seed fetching block andthe seed cover ring body are cooperated to realize feed fetching. When the hole sowing device assembly reverses, the central cam pushes the stirring and rotating sheet to reversely deflect, at the time, the seat rotation sheet does not move, the corresponding seed fetching block can be continuously pressed and abutted against the seed cover ring body so as to prevent the hole sowing device from being damaged, seed fetching is accurate, in addition, the seed fetching device has a simple mechanism, is reliable to work, has a long service life, can be easily assembled and maintained, and has thecharacteristics of being safe, labor-saving, convenient and efficient.

Description

technical field [0001] The present application relates to the technical field of agricultural seeding machinery, and relates to a reversible tie-rod briquetting type hole seeder. Background technique [0002] Existing seeders with hole-seeding devices are widely used, and their seed-taking devices are generally air-suction, socket-hole or seed-spoon-type. At present, the duckbill-type hole-seeding devices of clamping type are widely used, but due to The structure of the clamping device is relatively complicated, and it is usually impossible to reverse the seeder. However, when the tractor pulls the planter to stop, turn or reverse, it often accidentally reverses the seeder. On the one hand, it will cause damage to the internal parts of the seeder. It has to be shut down for maintenance. On the other hand, it is easy to cause the seeds in the seed chamber to pour back into the duckbill, which easily leads to multiple sowing in one hole, which wastes seeds and increases the so...

AI Technical Summary

Problems solved by technology

[0003] The purpose of this application is to provide a kind of cam crank arm clamping hole seeder, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the existing precision hole seeder has a complex structure, many parts, and reliable locking mechanism that allows reverse rotation. Poor performance, high manufacturing cost, time-consuming and labor-intensive maintenance, and easy damage to components when the hole seeder is reversed, resulting in delays in farming time and large losses
