Bionic rotary-cutting and stubble-breaking blade

Abstract

The invention discloses a bionic rotary tillage stubble-grinding general-purpose blade, which is composed of lateral tangent plane part, positive tangent plane part and transition part between lateral and positive tangent plane parts, wherein the positive and lateral tangent plane parts aren't in the same plane; the positive tangent plane bends along bending line of knife shaft.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a rotary tillage blade. Background technique [0002] Rotary tillage and stubble breaking are the two most common soil cultivation methods in China (especially in the north). Full-width rotary tillage is generally used for flat farming, such as paddy fields, vegetable fields, wheat fields, etc., and stubble is generally used for ridge farming in the north. There are many rotary tillers in foreign countries, but there is no separate stubble breaker. On some no-tillage seeders, stubble removal parts are installed in front of the seeder ditch opener to remove the stubble in the crop row. Domestic rotary tillage or stubble crushing operations have more than tens of thousands of single machines. In recent years, there have been some models that can complete two operations of rotary tillage and stubble crushing on one machine tool. There are two main types: (1) replace different...

AI Technical Summary

Problems solved by technology

If two operations of rotary tillage and stubble breaking are to be realized, the knife stick and the corresponding blades must be replaced with the existing blades. This operation is not only time-consuming, but also the operation efficiency is relatively low.
