Description

Stubble-cleaning and farming compound knife
Technical Field
The utility model relates to a rotary tillage cutter technical field especially relates to a stubble-cleaning farming compound sword.
Background
In the specific cultivation process of farmers, the cultivation resistance is too large due to the fact that the edge of the stubble ploughing cutter is too thick, some straws cannot be crushed at one time, some long straws are left on the ground, and some straws are buried underground, so that seeding is affected and interfered, the 1T245 rotary tillage cutter only has a soil breaking function and cannot achieve the deep ploughing effect, soil hardening is caused by cultivation every year, and the problems are solved by compounding the characteristics of the stubble ploughing cutter and the rotary tillage cutter to form a compound cutter in the prior art;
however, the existing compound knife is approximately in a 7-shaped shape when in use, deep ploughing of soil is difficult to carry out during rotary tillage, and meanwhile, most of the existing compound knives are not provided with parts for cutting off the side edge of a soil body, so that when the straw in the soil is doped and knotted, the straw in the soil can only be pulled out and cannot be cut off, the practicability is low, and the improvement is worth.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art, and provides a stubble-cleaning and farming compound knife.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a stubble-cleaning farming composite knife, includes handle of a knife and the blade that is connected, the mounting hole has been seted up on the handle of a knife, the blade includes integrated into one piece's connecting portion and kink, the tip of kink is provided with cutting edge A, the kink sets up perpendicularly on the terminal surface of connecting portion, the kink is along the clockwise bending of perpendicular line of being connected the face with connecting portion.
Preferably, the degree of clockwise bending of the bending part along a perpendicular line of a connecting surface with the connecting part is fifteen to twenty-five degrees.
Preferably, the degree of clockwise bending of the bending part along a perpendicular line connecting a surface with the connecting part is twenty degrees.
Preferably, a blade B is arranged on the side edge of the connecting part, and the blade B and the blade a are located on the same side surface.
Preferably, the aperture of the mounting hole is 125 MM.
Preferably, the tool handle and the tool body are integrally formed, and the surfaces of the tool handle and the tool body are sprayed with wear-resistant coatings.
The utility model provides a stubble-cleaning farming compound knife, beneficial effect lies in: the utility model discloses in compound mutually through the characteristics with traditional stubble-cleaning sword and rotary blade, realize the combined function of rotary tillage and stubble-cleaning, meet "7" font cutter among the prior art, the utility model provides a kink twists along the terminal surface axial of connecting portion, when actual stubble-cleaning rotary tillage, can upwards turn up soil to promote the efficiency of stubble-cleaning rotary tillage greatly, make this compound sword plough deeply more easily into the ground, offer cutting edge B simultaneously at the side of connecting portion, can excise the side of ploughing the soil, avoid straw doping to tie a knot in the soil simultaneously, the problem that can't cut off when ploughing, this compound sword simple structure is novel, and the practicality is stronger.
Drawings
Fig. 1 is a schematic structural view of a stubble-cleaning and cultivating compound knife provided by the utility model;
fig. 2 is a schematic structural view of a front view of the stubble ploughing and tilling compound knife provided by the present invention.
In the figure: 1. a knife handle; 2. a blade body; 201. a connecting portion; 202. a bending section; 203. a blade A; 204. a blade B; 3. and (7) installing holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a stubble-cleaning tillage composite knife includes a knife handle 1 and a knife body 2 connected with each other, a mounting hole 3 is provided on the knife handle 1, the knife body 2 includes a connecting portion 201 and a bending portion 202 integrally formed, a cutting edge a203 is provided at an end of the bending portion 202, the bending portion 202 is vertically disposed on an end surface of the connecting portion 201, and the bending portion 202 is clockwise bent along a perpendicular line connecting the connecting surface with the connecting portion 201.
In more detail, the bending part 202 is bent by fifteen to twenty-five degrees clockwise along a perpendicular line to a connection surface with the connection part 201.
Further, the degree of clockwise bending of the middle bending portion 202 along the perpendicular line connecting the surface with the connecting portion 201 is preferably twenty degrees.
In order to achieve a better stubble cleaning effect, a blade B204 is arranged on the side of the connecting part 201, and the blade B204 and the blade a203 are located on the same side.
The utility model discloses in compound mutually through the characteristics with traditional stubble-cleaning sword and rotary blade, realize the combined function of rotary tillage and stubble-cleaning, meet "7" font cutter among the prior art, the utility model provides a kink 202 twists along the terminal surface axial of connecting portion 201, when actual stubble-cleaning rotary tillage, can upwards turn up soil to promote the efficiency of stubble-cleaning rotary tillage greatly, make this compound sword plough deeply more easily into the ground, offer cutting edge B204 simultaneously at the side of connecting portion 201, can excise the side of ploughing the soil, avoid straw doping in the soil to tie a knot simultaneously, the problem that can't cut off when ploughing, this compound sword simple structure is novel, and the practicality is stronger.
