Description
Technical field
The utility model relates to a kind of rotary blade, particularly a kind of rotary tillage stubble-cleaning dual-purpose knife.
Background technology
Employed rotary blade generally is made up of handle of a knife and blade on the existing rotovator.An installing hole is arranged on the handle of a knife.Blade is provided with the bending section to about 120 ° of handle of a knife left side or right lateral bendings, and the front end of bending section is the cutter head part.One side of blade is blade.After rotary blade was fixed on the tool magazine of rotovator, blade was downward, during this cutter work, can only rotary tillage soil, and finish and loosen the soil, can not finish other work.
Summary of the invention
The utility model provides a kind of rotary tillage stubble-cleaning dual-purpose knife that can the rotary tillage soil can shred the root stubble again for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of rotary tillage stubble-cleaning dual-purpose knife, comprise blade and handle of a knife, described handle of a knife is provided with an installing hole that is connected with rotovator, described blade comprises rotary tillage portion and stubble-cleaning portion, and described stubble-cleaning portion is a described rotary tillage portion along the extension that knife face bends up or down.
The angle of described rotary tillage portion and described stubble-cleaning portion greater than 70 ° less than 120 °.
The angle of described rotary tillage portion and described stubble-cleaning portion greater than 80 ° less than 100 °.
The angle of described rotary tillage portion and described stubble-cleaning portion is 90 °.
Advantage and the good effect that the utlity model has are: after this dual-purpose knife was fixed on the tool magazine of rotovator, blade was downward, and rotary tillage portion is the vertical cut state, finishes the work in rotary tillage soil; Stubble-cleaning portion is the crosscut state, mainly finishes the work of chopping root stubble, plays the effect that chopping soil loosens the soil simultaneously; Rotary blade and stubble-cleaning cutter are united two into one, and a cutter is dual-purpose, in the process of rotary tillage and stubble-cleaning without tool changing, disposable stubble-cleaning and the rotary tillage two procedures finished, the saving of labor, save time, laborsaving, raise the efficiency nearly 50%.Can be used in most rotovators.
