Abstract
The utility model relates to a kind of pulverator plough knife structure of rotovator, comprise the cutter shaft being installed on driveshaft end, cutter shaft is installed colter sheet, described colter sheet is with curved structure, comprise symmetry and be installed on positive colter sheet 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; The convex surface side of positive colter sheet is with positive cutting teeth, and the convex surface side of anti-colter sheet is with anti-cutting teeth.The utility model is by the colter sheet of forward and reverse direction, and realize forward and reverse direction rotary tillage, its efficiency is high, effective; Colter sheet is curved structure, is beneficial to and clod is opened cutting, arranges cutting teeth, accelerates cutting speed, improves rotary tillage efficiency.
Description
Technical field
The utility model relates to technical field of agricultural machinery, especially a kind of hand-held rotovator.
Background technology
Rotovator completes cultivated, to harrow operation cultivation machinery.Because of its have hack ability strong, plough after the features such as earth's surface is smooth, and to be widely used.
Hand-held rotovator of the prior art, the structural design of its colter that loosens the soil is unreasonable, and rotary tillage efficiency is not high, poor effect.
Utility model content
The applicant, for the medium shortcoming of above-mentioned existing production technology, provides a kind of pulverator plough knife structure of rational in infrastructure, rotovator that operating efficiency is high.
The technical scheme that the utility model adopts is as follows:
A kind of pulverator plough knife structure of rotovator, comprise the cutter shaft being installed on driveshaft end, cutter shaft is installed colter sheet, described colter sheet is with curved structure, comprise symmetry and be installed on positive colter sheet 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; The convex surface side of positive 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 with the second sharp edge.
The perisporium of described cutter shaft is with the groove bar axially arranged along it.
Described positive colter sheet and anti-colter sheet comprise three pieces respectively.
The beneficial effects of the utility model are as follows:
The utility model is by the colter sheet of forward and reverse direction, and realize forward and reverse direction rotary tillage, its efficiency is high, effective; Colter sheet is curved structure, is beneficial to and clod is opened cutting, arranges cutting teeth, accelerates cutting speed, improves rotary tillage efficiency.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is the upward view of Fig. 2.
Wherein: 1, driving 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.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the pulverator plough knife structure of the rotovator of the present embodiment, comprise the cutter shaft 2 being installed on driving shaft 1 end, cutter shaft 2 is installed colter sheet, colter sheet is with curved structure, comprise symmetry and be installed on positive colter sheet 3 on cutter shaft 2 and anti-colter sheet 4, positive colter sheet 3 and anti-colter sheet 4 comprise three pieces respectively, respectively about cutter shaft 2 Central Symmetry; The concave curved surface of positive colter sheet 3 is towards cutter shaft 2 end, and the concave curved surface of anti-colter sheet 4 is towards driving shaft 1 end, and namely positive colter sheet 3 is arranged dorsad with anti-colter sheet 4.
For raising is to the cutting dynamics of 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 is with anti-cutting teeth 41, the cross section of positive cutting teeth 31 and anti-cutting teeth 41 is triangle, the external end edge of positive colter sheet 3 is with the first sharp edge 32, and the external end edge of anti-colter sheet 4 is with 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 the auxiliary cutting of clod.
The utility model is by the colter sheet of forward and reverse direction, and realize forward and reverse direction rotary tillage, its efficiency is high, effective; Colter sheet is curved structure, is beneficial to and clod is opened cutting, arranges cutting teeth, accelerates cutting speed, improves rotary tillage efficiency.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
