Problems solved by technology

The cutter of this technical solution is a chopping blade for returning straw to the field. Although the blockage of straw has been improved, because the operation method is carried out on the surface, the underground root system of the crop cannot be cut off, so the blockage caused by the root system cannot be solved. Large power consumption, poor working environment, damage to the covered ground surface, not conducive to sowing

It is characterized by that a mounting hole is set in the centre of said knife body, and on the outside of said knife body several knife teeth with identical form and size are set, and every knife tooth is formed from knife edge, auxiliary knife edge and knife back. Said invented design is reasonable, and its application is reliable.

Description

Technical field: [0001] The invention mainly relates to a no-tillage seeder, in particular to the structure of the cutter used for the anti-blocking device of the no-tillage seeder. Background technique: [0002] In recent years, the straw-covered no-till planting method has been more and more widely promoted in various parts of our country because it can store water and moisture, fertilize the soil, save energy and save labor. The traditional seeder cannot sow in the straw-covered land due to the blockage of the straw. In the prior art, the application number is 98218325.9, and the utility model patent titled "Gear-tooth anti-blocking device for no-tillage mulching seeder" discloses a structure of an anti-blocking device, which is mainly composed of a grass cutting disc, two It consists of a toothed weeding wheel and a ditch opener. The cutting knife of the above technical solution is a grass cutting disc, which is passive, and the effect of cutting straw is not good, and...
