Abstract
The invention relates to a scarifier coulter structure of a rotary cultivator. The scarifier coulter comprises a coulter shaft which is mounted at the end of a driving shaft, wherein a coulter blade is mounted on the coulter shaft; the coulter blade is provided with a curved surface-shaped structure, and comprises positive coulter blades and negative coulter blades; the positive coulter blades and the negative coulter blades are symmetrically mounted on the coulter shaft; the concave curved surfaces of the positive coulter blades face towards the end of the coulter shaft; the negative coulter blades face towards the end of the driving shaft; positive cutting teeth are formed in the convex surface sides of the positive coulter blades; negative cutting teeth are formed in the convex surface sides of the negative coulter blades. According to the scarifier coulter structure, the rotary cultivation in the positive and negative directions is realized through the positive and negative coulter blades, so that the scarifier coulter structure is high in efficiency and good in effect; the coulter blade is of the curved surface-shaped structure so that the clods can be turned over and cut; through the setting of the cutting teeth, the cutting speed is accelerated, and the rotary cultivation efficiency is improved.
Description
Technical field
The present invention relates to technical field of agricultural machinery, especially a kind of hand-held rotary cultivator.
Background technology
Rotary cultivator is the cultivation machinery completing to plough, harrow operation with tractor.Because of its have hack ability strong,
The features such as cultivated rear earth's surface is smooth, and be widely used.
Hand-held rotary cultivator of the prior art, the structure design of its colter that loosens the soil is unreasonable, and rotary tillage efficiency is not
High, poor effect.
Summary of the invention
The applicant is for the above-mentioned medium shortcoming of existing production technology, it is provided that a kind of rational in infrastructure, work efficiency
The pulverator plough knife structure of high rotary cultivator.
The technical solution adopted in the present invention is as follows:
The pulverator plough knife structure of a kind of rotary cultivator, including being installed on the cutter shaft of driveshaft end, cutter shaft is installed
Colter sheet, described colter sheet is with curved structure, including the positive colter sheet being symmetrically arranged on cutter shaft and anti-
Colter sheet, the concave curved surface of positive colter sheet is towards cutter shaft end, and the concave curved surface of anti-colter sheet is towards drive shaft end；Just
The convex surface side of colter sheet is with positive cutting teeth, and the convex surface side of anti-colter sheet is with anti-cutting teeth.
Further improvement as technique scheme:
The cross section of described positive cutting teeth and anti-cutting teeth is triangle.
The external end edge of described positive colter sheet is with the first sharp edge, and the external end edge of anti-colter sheet is sharp-pointed with second
Edge.
The perisporium of described cutter shaft is with the groove bar axially arranged along it.
Described positive colter sheet and anti-colter sheet include three pieces respectively.
Beneficial effects of the present invention is as follows:
The present invention colter sheet by forward and reverse direction, it is achieved forward and reverse direction rotary tillage, its efficiency is high, effect
Good；Colter sheet is curved structure, is beneficial to clod is opened cutting, arranges cutting teeth, accelerates cutting speed,
Improve rotary tillage efficiency.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of the present invention.
Fig. 2 is the front view of the present invention.
Fig. 3 is the upward view of Fig. 2.
Wherein: 1, drive shaft；2, cutter shaft；21, groove bar；3, positive colter sheet；31, positive cutting teeth；
32, the first sharp edge；4, anti-colter sheet；41, anti-cutting teeth；42, the second sharp edge.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Figure 1, Figure 2 and Figure 3, the pulverator plough knife structure of the rotary cultivator of the present embodiment, including installing
In the cutter shaft 2 of drive shaft 1 end, cutter shaft 2 being installed colter sheet, colter sheet is with curved structure, bag
Include the positive colter sheet 3 and anti-colter sheet 4 being symmetrically arranged on cutter shaft 2, positive colter sheet 3 and anti-colter sheet 4
Include three pieces respectively, respectively about cutter shaft 2 centrosymmetry；Just the concave curved surface of colter sheet 3 is towards cutter shaft 2 end,
The concave curved surface of anti-colter sheet 4 is towards drive shaft 1 end, and i.e. positive colter sheet 3 is arranged dorsad with anti-colter sheet 4.
For improving the cutting dynamics to clod and efficiency, the convex surface side of positive colter sheet 3 is with positive cutting teeth
31, the convex surface side of anti-colter sheet 4 cutting with anti-cutting teeth 41, positive cutting teeth 31 and anti-cutting teeth 41
Face is triangle, and the external end edge of positive colter sheet 3 is with the first sharp edge 32, the outer end marginal zone of anti-colter sheet 4
There is the second sharp edge 42.
The perisporium of cutter shaft 2 is with the groove bar 21 axially arranged along it, and groove bar 21 is beneficial to clod auxiliary cutting.
The present invention colter sheet by forward and reverse direction, it is achieved forward and reverse direction rotary tillage, its efficiency is high, effect
Good；Colter sheet is curved structure, is beneficial to clod is opened cutting, arranges cutting teeth, accelerates cutting speed,
Improve rotary tillage efficiency.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is joined
See claim, within protection scope of the present invention, any type of amendment can be made.
