The cutting knife solves the technical problem that in the prior art, the design is not reasonable enough and the circumferential rotation is easily caused. The cutting knife suitable for the field mower comprises a disc-shaped body, and a plurality of cutting teeth are evenly distributed on the periphery of the body. The cutting knife suitable for the field mower is characterized in that the cutting teeth and the body are connected into a whole, a fixing hole is formed in the center of the body, and a fixing structure for locating the body is arranged on the hole inner wall of the fixing hole. Compared with the prior art, the cutting knife suitable for the field mower has the advantages of being more reasonable in design, simpler in structure, firm in circumferential fixation, not prone to causing the rotation phenomenon, good in stability and long in service life.
Description
Technical field
The utility model belongs to the mower technical field, relates in particular to a kind of cutter that is applicable to mower.
Background technology
Mower claims again weeder, grass mower, grass pruning machine (Lawn Mower), be a kind of be used to cut the grass on a lawn, the semi-automatic machine tool of vegetation etc.It alleviates manpower, and is easy to operate, fully saves manpower and time, and environmental protection realizes the advantage of landscaping, so is widely used.Mower has reciprocating type and rotary two classes.Mower generally comprises actuation mechanism, frame, action bars and is arranged on blade on action bars, existing blade generally mostly is such structure: blade base, be provided with some teeth that cut in the blade base outer rim, its center is provided with installing hole, and general how many circles of this installing hole, when blade is arranged on action bars, to blade be fixed by at least one clamping element, but the blade of this structure easily occurs circumferentially to rotate, bad stability, the service life of virtually having reduced blade.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of design more reasonable, and cutter is fixed, the cutter that is applicable to mower of good stability.
For achieving the above object, the utility model has adopted following technical proposal: the cutter that originally is applicable to mower comprises body in the form of annular discs, be evenly distributed with some teeth that cut at the body outward flange, it is characterized in that, described tooth and the body formula that is connected as a single entity of cutting, be provided with fixing hole at the body center, be provided with fixed structure for this body of location at the hole of fixing hole inwall.
As a kind of prioritization scheme, in the above-mentioned cutter that is applicable to mower, described fixed structure comprises the spline on the hole inwall that is arranged on fixing hole.Can prevent that body from circumferentially rotating.
In the above-mentioned cutter that is applicable to mower, described spline tooth number is 90 teeth.
In the above-mentioned cutter that is applicable to mower, described fixing hole is provided with the keyway that wears for flat key.
In the above-mentioned cutter that is applicable to mower, the described number of teeth amount of cutting is 46 teeth.
In the above-mentioned cutter that is applicable to mower, described body circumferencial direction is provided with some through holes, and this through hole cuts between tooth and fixing hole described.
In the above-mentioned cutter that is applicable to mower, described number of openings is 6.
Compared with prior art, the advantage that originally is applicable to the cutter of mower is: 1, design is more reasonable, and structure is simpler.2, cutter is circumferentially fixed, is difficult for rotating phenomenon, good stability.3, long service life.
Description of drawings
Fig. 1 is the perspective view that the utility model provides.
In figure, body 1, cut tooth 11, fixing hole 12, spline 12a, keyway 13, through hole 14.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, originally the cutter that is applicable to mower comprises body in the form of annular discs 1, at the even some teeth 11 that cut that distribute of body 1 outward flange, in order to be easy for installation and removal, be provided with fixing hole 12 at body 1 center, be provided with fixed structure for this body 1 of location at the hole of fixing hole 12 inwall.Concrete, the fixed structure here comprises the spline 12a on the hole inwall that is arranged on fixing hole 12; This spline 12a number of teeth is 90 teeth.Spline 12 can circumferentially rotate to this body 1, guarantees the firm and stable of connection.
In addition, in the present embodiment, be provided with the keyway 13 that wears for flat key on fixing hole 12.Further strengthen the fixing of connection.
In this enforcement, cutting tooth 11 quantity is 46 teeth.Be provided with some through holes 14 on body 1 circumferencial direction, this through hole 14 cuts between tooth 11 and fixing hole 12 described.Prioritization scheme, through hole 14 quantity here are 6.
The advantage of the present embodiment is: cutter is fixed, has stopped the phenomenon that cutter circumferentially rotates, and in addition, has further improved the stability when cutter rotates.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
