Active driving lever type anti-blocking mechanism

Abstract

The invention belongs to the technical field of agricultural machinery, and in particular relates to an active driving lever type anti-blocking mechanism. The active driving lever type anti-blocking mechanism comprises a rack, furrowing blades, a power transferring device and an anti-lockage device, wherein the furrowing blades are symmetrically fixedly connected on the rack; the power transferring device is arranged on the rack between the two adjacent furrowing blades; the power output by a tractor is transferred to the anti-blockage device arranged between the adjacent furrowing blades; the anti-blockage device comprises a three-connecting-rod moving mechanism which is formed by an anti-blockage device swinging arm, a connecting section of an anti-blockage device driving lever and an anti-blockage device rotating arm; the anti-blockage device driving lever is driven by a driving shaft of the anti-blockage device to reciprocate front and back or up and down so that straws between the adjacent furrowing blades is lifted to the part in back of the furrowing blades so as to achieve the active anti-blockage function. The active driving lever type anti-blocking mechanism disclosed by the invention has a simple structure; and the front end of the straw lifting section of the driving lever is not inserted into soil when the anti-blockage device driving lever reciprocates, therefore, the active driving lever type anti-blocking mechanism has the advantages of having low power consumption and high anti-blockage capacity, being capable of realizing no-tillage seeding in a condition of high straw coverage, being applicable to no-tillage corn seeding machines, and being beneficial to promoting the popularization of conservation tillage.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to an active lever type anti-blocking device. Background technique [0002] Conservation tillage is an advanced agricultural farming method that implements no-tillage and less-tillage on farmland, reduces soil tillage as much as possible, and covers the surface with crop stalks and residues to reduce soil wind and water erosion, and improve soil fertility and drought resistance. The no-tillage seeder is the main carrier for the implementation of this technology, but when the no-tillage seeder is operating on a large amount of straw-covered land, blockage between adjacent openers is prone to occur, resulting in the failure of the machine tool to work normally, which requires no-tillage The seeder has good anti-blocking performance. In order to solve the problem of equipment blockage in no-tillage seeding with a large amount of straw coverage, it is generally necessary...

AI Technical Summary

Problems solved by technology

The two anti-blocking parts do not penetrate into the soil, and the speed is low, but the anti-blocking ability is poor. When the amount of straw covers a large amount, the straw that is shifted to both sides is easy to block between adjacent openers.
