Abstract
The invention relates to a stubble chopping and slurry stirring knife of a paddy field and a manufacturing method of the stubble chopping and slurry stirring knife of the paddy field, wherein the stubble chopping and slurry stirring knife comprises a knife handle and a knife body, wherein a knife blade is formed on the knife body; a cutting head is formed on a front section of the knife body; the adopted technical scheme is characterized by that the knife blade of the knife body is bent towards one side from a boundary between the knife handle and the knife body to form an S shape or a reverse S shape in terms of the knife blade toward the knife body; and the cutting head on the front end of the knife body is bent towards one side along the S-shaped bending direction of the knife blade. The manufacturing method comprises the following steps: cutting strip steel and then heating; directly rolling the heated strip steel by a forging roll, rolling and molding the knife body together with the knife blade, and performing thermal treatment on the knife handle and the knife body respectively according to different hardness requirements, wherein the quenching hardness of the knife handle portion is HRC 42-49, and the quenching hardness of the knife body portion is HRC 52-58. The stubble chopping and slurry stirring knife provided by the invention is strong in capability of breaking soil and stirring slurry, a knife shaft does not twine grass in a working process, and a stubble chopping property is good. Under the same load, the stubble chopping and slurry stirring knife is capable of allowing rather high working speed and rather large plowing width and achieving more flat plowed land.
Description
Technical field:
The invention belongs to agricultural machinery, be specifically related to the paddy field stubble-cleaning that a kind of paddy field stubble-cleaning change-can mixer uses and stir slurry cutter and preparation method thereof.
Background technology:
At present, the paddy field stubble-cleaning knife of domestic use mostly is a kind of arc cutter tooth, and when carrying out the operation of water field ploughing ground, stubble-cleaning, whole ground effect are pretty good, can solve the problem that cutter shaft twines grass, but exist power consumption excessive, and hack stirs the problems such as slurry aberrations in property.
Summary of the invention:
The present invention is directed to above-mentioned the deficiencies in the prior art, provide a kind of paddy field paddy field stubble-cleaning that the stubble-cleaning change-can mixer is used to stir slurry cutter and preparation method thereof, its stubble-cleaning, whole ground are effective, cutter shaft straw winding during operation, and its power consumption is low, and hack stirs that to starch performance good.
Paddy field of the present invention stubble-cleaning stirs the slurry cutter, comprise handle of a knife and blade, blade is provided with blade, the leading portion of blade is cutter head, the technical scheme that adopts is: the blade in face of blade is seen, from the line of demarcation of handle of a knife and blade, the blade of blade is to the S-type or anti-S type of curving, the cutter head of blade front end along the S of blade type bending direction to a lateral buckling.
Preferably, the prone bending radius of described cutter head is R100～120mm.
Preferably, described blade is two-sided blade, and the angle of the center line of its single face and blade cross section is 10～13 °.
Preferably, a side opposite with blade is provided with bandy arc holddown groove near the end on the described handle of a knife.
Preferably, the overbending direction of the two side direction cutter heads in the cross section of described blade is crooked.
The preparation method that paddy field of the present invention stubble-cleaning stirs the slurry cutter is: carry out heat treated after will being with steel to cut off, band steel after the heating directly rolls with forging roll, its blade and blade be roller-compaction together, handle of a knife and blade are heat-treated by the different hardness requirement respectively, and wherein the shank portion quenching hardness is that HRC42～49, blade incomplete quench hardness are HRC52～58.
The invention has the beneficial effects as follows: this paddy field stubble-cleaning stirs the slurry cutter, the cutter radius of clean-up little (about R190), and its crooked shape is reasonable in design, and hack, to stir the slurry ability strong, and cutter shaft straw winding during operation, stubble-cleaning performance are good.Under identical load condition, can allow higher operating rate and larger working width, the soil is more smooth after ploughing.

Embodiment:
With reference to each accompanying drawing, this paddy field stubble-cleaning stirs the slurry cutter, comprises handle of a knife 1 and blade 2, and blade 2 is provided with blade 4, the leading portion of blade 2 is cutter head 3, it is characterized in that: the blade 4 in face of blade 2 sees, from the line of demarcation of handle of a knife 1 and blade 2, the blade 4 of blade 2 is to the S-type or anti-S type of curving, the cutter head 3 of blade 2 front ends along the S of blade 4 type bending direction to a lateral buckling, during the tool roller axis rotation, the arc of cutter head 3 bendings plays Sliding cutting action to soil, and resistance is little, straw winding.Cutter head 3 prone bending radius are 110mm.Blade 4 is two-sided blade, and the angle of the center line of its single face and blade cross section is 12 °.A side opposite with blade 4 on the handle of a knife 1 is provided with bandy arc holddown groove 6 near the end.The overbending direction of the two side direction cutter heads 3 in the cross section of blade 2 is crooked.
During installation, the present invention is installed on the tool rest of tool roller axis of paddy field stubble-cleaning change-can mixer, withstand and coincide with the axial plane of tool roller axis with the holddown groove 6 of handle of a knife 1 of the present invention, and then with bolt handle of a knife 1 is fastened on the tool rest on the tool roller axis, two in the same fitting plane are stirred each other symmetry of slurry cutter, and blade 4 is towards direction of advance.During operation, two two round and smooth curved blades that stir the slurry cutter can vanish the root stubble and are pressed in the mud, to the blade 4 of the S-shaped or anti-S shape of a side, soil block can be downcut and smash fully and stir, to finish hack, stubble-cleaning to ground, paddy field, to stir slurry, grading operation.
The preparation method that paddy field of the present invention stubble-cleaning stirs the slurry cutter is: carry out heat treated after will being with steel to cut off, band steel after the heating directly rolls with forging roll, its blade 2 and blade 4 be roller-compaction together, handle of a knife 1 is heat-treated by the different hardness requirement respectively with blade 2, and wherein handle of a knife 1 incomplete quench hardness is that HRC45, blade 2 incomplete quench hardness are HRC54.
