Abstract
The invention discloses a rotary knife, and relates to the technical field of knife tools. The rotary knife comprises a blade body, cutting edges are arranged on sides of two ends of the blade body, bent portions are arranged on the blade body and positioned on rear sides of the cutting edges, and a fixing hole is formed in the middle of the blade body. The rotary knife is characterized in that grooves are formed in the blade body and positioned among the fixing hole and the two ends of the blade body. Strength can be enhanced, and the rotary knife is convenient and simple to machine and produce and low in cost.
Description
Technical field:
The present invention relates to cutting-tool engineering field, specifically a kind of cutter that revolves.
Background technology:
Revolving a cutter, is the power that utilizes gasoline engine, by transmission system, drives mowing capstan High Rotation Speed, makes to be contained in the blade High Rotation Speed on capstan, produces certain cutting force, and weeds are cut off, and plays the effect of weeding.This cutter that revolves not only requires hardness high, can make very sharp blade, but also requires higher intensity, in the process that cutter is mowed in fast rotational, can not produce distortion.In prior art, the intensity that cutter is revolved in general increase is both by changing its material, or the processing technology of its material is done to certain specially treated, and this mode cost is higher, when it is done to specially treated, also can increase longer process time.
Summary of the invention:
It is a kind of simple and convenient that technical problem to be solved by this invention is to provide, and intensity is high, can reduce the cutter that revolves of manufacturing cost.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of cutter that revolves, comprise blade body, the two ends sidepiece of described blade body is provided with blade, the rear side that is positioned at blade in blade body is provided with bending part, centre position in blade body is provided with fixing hole, it is characterized in that: in described blade body, between fixing hole and both ends, be provided with groove.
The blade at described blade body two ends becomes to be symmetrical arranged with the center of bending part about blade body.
Described groove is elongate slots, groove trough rim position all by being provided with fillet.
Groove in the present invention can increase the intensity that blade body is certain, processes simple and convenient.Bending part is that being not easy of making snaps into for the grass after cutting is thrown away.Groove the trough rim position better effects if of all gaining in strength by being provided with fillet.
The invention has the beneficial effects as follows: the present invention can gain in strength, and processing is convenient and simple, and cost is low.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of cutter that revolves, comprise blade body, the two ends sidepiece of blade body is provided with blade 1, the rear side that is positioned at blade 1 in blade body is provided with bending part 2, in the centre position of blade body, be provided with fixing hole 3, in blade body, between fixing hole 3 and both ends, be provided with groove 4.The blade 1 at blade body two ends becomes to be symmetrical arranged with the center of bending part 2 about blade body.Groove 4 is elongate slots, groove 4 trough rim position all by being provided with fillet.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
