Abstract
The utility model relates to a novel rotary blade which is composed of a blade handle and a blade body. The blade handle and the blade body are integrally formed. The novel rotary blade is characterized in that an included angle between the center axis of the blade handle and the center axis of the blade body is 108 degrees, the blade body is composed of a blade back section and a rotary cutting section, the blade back section is located on the upper portion of the blade body and accounts for 1/5-2/5 of the width of the blade body, and the rotary cutting section is located on the lower portion of the blade body and accounts for 3/5-4/5 of the width of the blade body. The novel rotary blade has the advantages of being scientific and reasonable in design, good in rotary tillage effect, high in speed, good in abrasion resistance, long in service life, high in creativity and the like.
Description
Technical field
The utility model belongs to farm machinery parts field, particularly a kind of Novel rotary tillage cutter.
Background technology
Rotary blade is to be used for a kind of agricultural machinery accessory of Porous soil in agricultural production, is widely used at present.Mostly rotary blade in the past is supporting for miniature farm machinery, and its volume, structure mainly are applicable to miniature farm machinery; Particularly existing rotary blade is more straight, and when digging, the section of burying is little, and the dead angle of digging is large, and the effect of digging is not ideal; Have, existing rotary blade blade, back section hardness are identical, cause the blade poor toughness again, frangibility, and blade part hardness is relatively low, wears no resistance.Development along with agriculture large-scale production; large-scale agricultural machinery is occupied an leading position; and supporting farm machinery parts adaption demand not yet fully with it, market needs that a kind of volume is large, structure can adapt to the large-scale agricultural machinery farming and ploughing speed is fast, effective, the Novel rotary tillage cutter of long service life badly.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and adapts to the large-scale agricultural machinery farming, ploughing speed is fast, effective and wearability is good, the Novel rotary tillage cutter of long service life.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of Novel rotary tillage cutter, consisted of by handle of a knife and blade, handle of a knife, blade are made into integration, it is characterized in that: the angle of the center line of described handle of a knife and the center line of described blade is 108 °, described blade is made of back section and rotary-cut section, the back section is positioned at blade top and accounts for blade width 1/5～2/5, and the rotary-cut section is positioned at the blade bottom and accounts for blade width 3/5～4/5.
And described handle of a knife is that hardness is the secondary troostite of HRC40 ± 2.
And the specification of described blade is: 220 millimeters of length, wide 56-66 millimeter, thick 2-5 millimeter.
And described back section is that hardness is the tempered martensite of HRC50 ± 2.
And described rotary-cut section is that hardness is the tempered martensite of HRC64 ± 2.
Advantage of the present utility model and good effect are:
1. the angle of this Novel rotary tillage cutter handle of a knife center line and blade center line is less, the segment length that buries when digging, and the dead angle is little, and rotary tillage is effective, and speed is fast;
2. this Novel rotary tillage cutter hardness, rational in infrastructure, wearability is good, long service life.
3. this Novel rotary tillage cutter design science is reasonable, has the advantages such as rotary tillage speed is fast, effective, wearability is good, long service life, is a kind of Novel rotary tillage cutter with higher innovation.

Description of reference numerals:
1-handle of a knife, 2-pilot hole, 3-handle of a knife blade center line angle, 4-back section, 5-rotary-cut section,
The center line of the center line of 6-blade, the virtual back section of 7-rotary-cut section cut-off rule, 8-handle of a knife.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of Novel rotary tillage cutter, consisted of by handle of a knife 1 and blade, handle of a knife, blade are made as one, its innovation is: the center line 8 of handle of a knife is 108 ° with the angle a of the center line 6 of blade, label is 3, and blade comprises back section 4 and rotary-cut section 5, and back section, rotary-cut section are divided and be made as up and down one, the back section is positioned at blade top and accounts for 1/5～2/5 of blade width, and the rotary-cut section is positioned at the blade bottom and accounts for blade width 3/5～4/5.
The specification of blade is: 220 millimeters of length, wide 56-66 millimeter, thick 2-5 millimeter.Described handle of a knife is that hardness is the secondary troostite of HRC40 ± 2.The back section is that hardness is the tempered martensite of HRC50 ± 2.The rotary-cut section is that hardness is the tempered martensite of HRC64 ± 2.
Between handle of a knife and blade, between back section and rotary-cut section (virtual back section and rotary-cut section cut-off rule 7 both sides) its hardness has the nature changeover portion, is not completely different.
The operation principle of this Novel rotary tillage cutter is:
Before carrying out rotary tillage, the utility model is pacified specification requirement be assemblied on rotary tillage shaft by pilot hole 2; When carrying out rotary tillage process, (angle of original rotary blade handle of a knife center line and blade center line is about 120 ° because the angle of this Novel rotary tillage cutter handle of a knife center line and blade center line is less, the angle of Novel rotary tillage cutter handle of a knife center line and blade center line is about 108 °), so its section of burying is longer, the soil that stirs is more, the dead angle of digging is little, and the Porous soil effect is better; Simultaneously, except due to volume own large, also because its back section hardness is moderate, can escort and support the rotary-cut section frangibility not be made as one with it, rotary-cut section hardness is higher, and wearability is good, therefore long service life, 1 Novel rotary tillage cutter is equivalent to 5 original blades to be used.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
