Abstract
The utility model discloses a bend-resistant fracture-resistant rotary blade which comprises a shank. A fixing hole is formed in the upper middle of the shank and used for fixing the shank and a rotary cultivator blade holder, a blade body is integrally connected with the shank, a blade head bending towards one side is arranged at the end of the blade body, a connecting portion from the shank to the blade body is of a bent structure, a reinforcing tape is arranged at the bent structure, the reinforcing tape and the blade body are structurally integrated, one surface of the reinforcing tape is of a concave structure, and the other surface of the reinforcing tape is of a projecting structure. The bend-resistant fracture-resistant rotary blade is not easy to deform or fracture under large external force, and is high in practicability and easy to popularize and apply.
Description
Technical field
The utility model relates to a kind of farm machinery parts, especially relates to a kind of resistance to curved anti-disconnected rotary blade.
Background technology
Rotary blade, is one of main farm machinery parts of agriculture cultivation of fields, is normally fixed on rotovator, and in the time of farming, cutter head can be turned over its soil.Existing rotary blade, for the wear-resisting problem of its cutter head, improves, as ZL2012201431716 patented technology, has improved greatly the service life of cutter head, has saved the cost of material, has improved operating efficiency.But new problem is, because handle of a knife to the connecting portion of cutter hub is bending structure, its surface smoothing, so twisting resistance reduces relatively, in the situation that being subject to larger external force, easily occur bending and deformation or rupture, therefore, having a kind of novel resistance to curved anti-disconnected rotary blade to be supplied.
Utility model content
The purpose of this utility model, just in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of in the situation that external force is larger, not yielding, not a kind of resistance to curved anti-disconnected rotary blade of easy fracture.
The utility model is achieved by following technical proposals: a kind of resistance to curved anti-disconnected rotary blade, comprise handle of a knife, the upper middle part of described handle of a knife be provided with for the fixing fixing hole of rotovator tool rest, what be connected with described handle of a knife one has a cutter hub, the end of described cutter hub is provided with the cutter head to curving, described handle of a knife to the connecting portion of cutter hub is bending structure, position in described bending structure, be provided with the reinforcing band being structure as a whole with cutter hub, described reinforcing band is simultaneously concave structure, and another side is that convex type structure forms.
The specification of described concave structure is long 55-65mm, wide 5-15mm.
The specification of described convex type structure is long 65-75mm, wide 15-25mm.
The beneficial effects of the utility model are:
One. in prior art, because cutter hub is subject to the effect of external force, 95% cutter hub is all to the contrary curving of crooked cutter head or fracture, the utility model is the knee to cutter hub at handle of a knife, be provided with the reinforcing band being structure as a whole with cutter hub, described reinforcing band is simultaneously concave structure, and specification is 55-65mm, wide 5-15mm.Another side is that convex type structure forms, and specification is long 65-75mm, wide 15-25mm.Therefore, increased the forniciform twisting resistance of connecting portion, when being subject to larger External Force Acting, made cutter hub not yielding, easy fracture not, has improved the whole service life of cutter.
Two. the utility model is reasonable in design, does not increase cost of manufacture and raw-material cost.
Three. the utility model, practicality is high, is easy to apply.
Accompanying drawing explanation
Fig. 1 is prior art rotary blade structural representation.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the plan structure schematic diagram of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As Fig. 2, shown in Fig. 3, a kind of resistance to curved anti-disconnected rotary blade, comprise handle of a knife 1, the upper middle part of described handle of a knife 1 be provided with for the fixing fixing hole 2 of rotovator tool rest, what be connected with described handle of a knife 1 one has a cutter hub 3, the end of described cutter hub 3 is provided with the cutter head 4 to curving, described handle of a knife 1 to the connecting portion of cutter hub 3 is bending structure, position in described bending structure, be provided with the reinforcing band 5 being structure as a whole with cutter hub 3, described reinforcing band 5 one sides are concave structure, and another side is that convex type structure forms.The specification of the utility model concave structure can be long 55-65mm, wide 5-15mm, long 60mm preferably, wide 10mm; The specification of convex type structure described in the utility model can be long 65-75mm, wide 15-25mm, long 70mm preferably, wide 20mm.
Preparation method of the present utility model is: the crooked position at its cutter hub stamps out a groove by the mode of punching press, the recessed position of its groove is in the front of cutter hub, the position of projection is at the back side of cutter hub, therefore, when in use, the stress point of cutter hub crooked position is strengthened, and then has reached not yielding, not the positive effect of easy fracture.
Claims (3)
1. a resistance to curved anti-disconnected rotary blade, comprise handle of a knife, the upper middle part of described handle of a knife be provided with for the fixing fixing hole of rotovator tool rest, what be connected with described handle of a knife one has a cutter hub, the end of described cutter hub is provided with the cutter head to curving, described handle of a knife to the connecting portion of cutter hub is bending structure, it is characterized in that, at the position of described bending structure, be provided with the reinforcing band being structure as a whole with cutter hub, described reinforcing band is simultaneously concave structure, and another side is that convex type structure forms.
2. a kind of resistance to curved anti-disconnected rotary blade according to claim 1, is characterized in that, the specification of described concave structure is long 55-65mm, wide 5-15mm.
3. a kind of resistance to curved anti-disconnected rotary blade according to claim 1, is characterized in that, the specification of described convex type structure is long 65-75mm, wide 15-25mm.
