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.

Embodiment Construction

[0013] figure 1 The structure of the general blade of the bionic rotary tillage stubble of the present invention is shown, in figure 1 Among them, the coordinate origin O is the intersection point of the side cutting surface of the blade and the centerline Z of the cutter roller axis, figure 1 The upper part of the above shows the schematic diagram of the structure of the universal blade in the XYZ coordinate system, wherein the dotted line part is the projection of the tangent surface of the universal blade in the XOY plane, figure 1 The lower part of represents the projection of this universal blade in the YOZ plane. In the XYZ Cartesian coordinate system, the Z axis is the center line of the cutter roller axis, the side cut surface is in the XOY plane, but the tangent surface is not in the XOY plane, and it is bent toward the Z axis along the bending line, such as figure 1 shown in the lower part. The transition face (where the QS surface is located) is located between t...

Abstract

The invention relates to a general-purpose blade for bionic rotary tillage stubble, which is mainly composed of a side cutting surface with a side cutting edge, a tangential cutting surface with a tangential cutting edge, and a transitional surface located between the side cutting surface and the tangential cutting surface and having a transition edge. The tangent face and the side cut face are not in the same plane, and the tangent face is bent along the bending line knife stick axis. The general-purpose blade for bionic rotary tillage and stubble cutting of the present invention has the characteristics of reduced resistance and good desorption performance, and achieves simplified structure, simple operation, and convenient use and adjustment, thereby facilitating the popularization and application of machines and tools.

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...
