Abstract

The utility model provides a rotary blade, and belongs to the field of agricultural machines. The rotary blade is composed of a blade handle, a blade body and a blade tip. A fixed installation hole is formed in the blade handle, the blade body is formed by an arc blade edge and an arc blade back integrally, a linear blade edge of the blade tip is matched with the arc blade edge of the blade body in a tangent mode, the blade body bends towards the left or the right of the blade handle by 42-48 degrees, the operation width of the rotary blade is 90+/-2.0 millimeters, the thickness of the blade body is gradually reduced from the blade handle side to the blade tip side and from the arc blade back side to the arc blade edge side, and the thickness of the arc blade edge is not more than 2 millimeters. By means of the rotary blade, winding of weeds on the rotary blade and a blade shaft is eliminated, quality of rotary tillage and hacking operation is improved, and the rotary blade has the advantages of being simple in structure, reasonable in design, reliable in use, few in failure, good in operation quality, and high in efficiency.

Description

Rotary blade
Technical field
The utility model belongs to agricultural machinery, relates generally to the rotary tillage process parts on rotary tillage soil-working facility.
Background technology
Rotovator is one of main force's type of current the northern area of China dry land tillage operation, and the structural design of its rotary blade affects and determining rotary tillage process quality, operating efficiency and fault rate.And existing rotary blade is because of Structure Designing Problem, during ubiquity operation, be easily wound around the problem of weeds and hack weak effect, and after being wound around weeds, removing is very difficult, labour intensity is large, and facility operating efficiency is low.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, and design provides a kind of rotary blade of new construction, reaches reduction and reduce weeds the object that rotary blade is wound around to probability, raising hack operation quality.
Basic Design of the present utility model is, rotary blade is by handle of a knife, blade, point of a knife forms, on described handle of a knife, be provided with fixed installation hole, described blade entirety consists of arc shaped blade and the arc surfaced knife back, the tangent cooperation of arc shaped blade of the linearity blade of point of a knife and blade, described blade with respect to handle of a knife to the left or right side bending, bending angle α is 42-48 °, the working width L of described rotary blade is 90 ± 2.0 millimeters, the thickness of described blade is from handle of a knife one side direction point of a knife one side attenuate gradually, and from the arc surfaced knife back one side direction arc shaped blade one side attenuate gradually, described arc shaped blade cutting edge thickness H is≤2 millimeters.
The utility model adopts entirety to be the combined structure of point of a knife of blade and the linearity blade of arcuation crescent moon body, the winding of weeds to rotary blade and cutter shaft when avoiding and having eliminated rotary tillage process, and improved rotary tillage hack quality, there is feature simple in structure, reasonable in design, that use is reliable, fault is few, operation quality good, operating efficiency is high.
