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.
The interior hinge formula drag reduction colter of rotovator of the prior art, the structural design of its colter 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 interior hinge formula drag reduction colter of rational in infrastructure, rotovator that operating efficiency is high.
The technical scheme that the utility model adopts is as follows:
A kind of interior hinge formula drag reduction colter of rotovator, comprise on cutter shaft, cutter shaft and colter sheet is installed, described colter sheet comprises symmetry and is installed on positive colter sheet on cutter shaft and anti-colter sheet, the positive bending part that the outer end of positive colter sheet and the outer end of anti-colter sheet bend with oriented cutter shaft outer end respectively and reflexed turn of bilge; Cutter shaft between described positive colter sheet and anti-colter sheet is provided with interior reamer, and interior reamer is disc-shaped structure, and it is with and spaced cutting teeth symmetrical about its center;
With the first drag reduction hole on described positive colter sheet, the concave side of its positive bending part is with the first cutting;
With the second drag reduction hole on described anti-colter sheet, the concave side of its reflexed turn of bilge is with the second cutting;
With the 3rd drag reduction hole on described cutting teeth.
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; Cutter shaft is arranged interior reamer, secondary rubbing is carried out to the earth opened through colter sheet, avoid bulk earth to exist, improve rotary tillage efficiency; Reduce colter sheet and the resistance between interior reamer and clod by drag reduction hole, improve the cutting dynamics to clod by cutting, thus improve rotary tillage efficiency and effect further.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model.
Wherein: 1, cutter shaft; 2, positive colter sheet; 21, positive bending part; 22, the first cutting; 23, the first drag reduction hole; 3, anti-colter sheet; 31, reflexed turn of bilge; 32, the second cutting; 33, the second drag reduction hole; 4, interior reamer; 41, cutting teeth; 42, the 3rd drag reduction hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the interior hinge formula drag reduction colter of the rotovator of the present embodiment, comprises on cutter shaft 1, cutter shaft 1 and installs colter sheet, and colter sheet comprises symmetry and is installed on positive colter sheet 2 on cutter shaft 1 and anti-colter sheet 3, and positive colter sheet 2 and anti-colter sheet 3 comprise three groups respectively; The positive bending part 21 that the outer end of positive colter sheet 2 and the outer end of anti-colter sheet 3 bend with oriented cutter shaft 1 outer end respectively and reflexed turn of bilge 31, positive bending part 21 and reflexed turn of bilge 31 bending dorsad; Cutter shaft 1 between positive colter sheet 2 and anti-colter sheet 3 is provided with interior reamer 4, interior reamer 4 is disc-shaped structure, it is with and spaced cutting teeth 41 symmetrical about its center, and cutting teeth 41 is traditionally arranged to be 4, and cutting teeth 41 is arranged counterclockwise or clockwise around the center of interior reamer 4.
With the first drag reduction hole 23 on positive colter sheet 2, the concave side of its positive bending part 21 is with the first cutting 22; With the second drag reduction hole 33 on anti-colter sheet 3, the concave side of its reflexed turn of bilge 31 is with the second cutting 32; With the 3rd drag reduction hole 42 on cutting teeth 41.Reduce colter sheet and the resistance between interior reamer and clod by the first drag reduction hole 33, drag reduction hole 23, second and the 3rd drag reduction hole 42, improve the cutting dynamics to clod by the first cutting 22, second cutting 32, thus improve rotary tillage efficiency and effect.
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; Cutter shaft is arranged interior reamer, secondary rubbing is carried out to the earth opened through colter sheet, avoid bulk earth to exist, improve rotary tillage efficiency; Reduce colter sheet and the resistance between interior reamer and clod by drag reduction hole, improve the cutting dynamics to clod by cutting, thus improve rotary tillage efficiency and effect further.
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.
