Abstract
The utility model belongs to the technical field of mowing machines, and relates to cutters, in particular to a blade of an improved structure. The blade of the improved structure solves the technical problems that the prior art is not reasonable in design and blade fixing is not firm. The blade of the improved structure comprises a bar-shaped body, the middle of the body is provided with a mounting hole, at least two cutting heads are arranged on the body, and two locating holes which are used for locating in the circumferential direction, penetrate through the body in the axial direction and are respectively located on the two sides of the mounting hole are formed in the body. Compared with the prior art, the blade of the improved structure has the advantages that the design is more reasonable, the structure is simpler, fixation of the blade is firm in the circumferential direction, rotating phenomenon is not prone to happening, stability is good, and service life is long.
Description
Technical field
The utility model belongs to the mower technical field, relates to cutter, relates in particular to a kind of structure improved blade.
Background technology
Mower claims again weeder, grass mower and grass pruning machine, 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 cutter heads in the blade base outer rim, its center is provided with installing hole, when this blade is arranged on action bars, to blade be fixed by at least one clamping element, this blade is in the moment of whole mower startup, easily occur between blade and clamping element circumferentially to rotate, shortened the service life of blade, and reduced the stability when mower is worked.
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 blade is fixed, is difficult for occuring the circumferentially structure improved blade of rotation.
For achieving the above object, the utility model has adopted following technical proposal: this structure improved blade comprises the body that is strip, be provided with installing hole in the middle part of body, be provided with at least two cutter heads on body, it is characterized in that, described body is provided with two locating holes that axially run through described body and lay respectively at described installing hole both sides.Locating hole is used for circumferentially location.
In above-mentioned structure improved blade, described installing hole is provided with keyway.Play further fixation.
As another kind of scheme, in above-mentioned structure improved blade, described installing hole hole wall is provided with spline.Play further fixation.
In above-mentioned structure improved blade, described body is cuboid, and described cutter head is separately positioned on the long limit of described body.
In above-mentioned structure improved blade, the blade of described cutter head is towards the opposite.
In above-mentioned structure improved blade, described cutter head is fixed on body by welding or retaining mechanism.
In above-mentioned structure improved blade, described retaining mechanism comprises some screws that wear on cutter head, is provided with some screws at body, and described screw arranges and is threaded with screw is corresponding one by one.
In above-mentioned structure improved blade, described spline tooth number is 30 teeth.
Compared with prior art, the advantage of this structure improved blade is: 1, design is more reasonable, and structure is simpler.2, blade is circumferentially fixed, is difficult for rotating phenomenon, good stability.3, long service life.
Description of drawings
Fig. 1 is embodiment one structural representation that the utility model provides.
Fig. 2 is embodiment two structural representations that the utility model provides.
In figure, body 1, screw 1a, installing hole 11, keyway 11a, spline 11b, locating hole 12, cutter head 2, screw 2a.
Embodiment
Be below the specific embodiment and by reference to the accompanying drawings of utility model, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment one
As shown in Figure 1, this structure improved blade comprises the body 1 that is strip, be provided with installing hole 11 at body 1 middle part, be provided with at least two cutter heads 2 on body 1, in order to prevent that body 1 from circumferentially rotating, be provided with two locating holes 12 that axially run through described body 1 and lay respectively at described installing hole 11 both sides on body 1.In order further to prevent rotating, be provided with keyway 11a on installing hole 11.
In addition, the body 1 in the present embodiment is cuboid, and described cutter head 2 is separately positioned on the long limit of described body 1, and the blade of described cutter head 2 is towards the opposite.Further, here cutter head 2 by the welding or retaining mechanism be fixed on body 1.The retaining mechanism of the present embodiment comprises some screw 1a that are located on cutter head 2, is provided with some screw 2a at body 1, and described screw 1a arranges and is threaded with screw 2a is corresponding one by one.
Embodiment two
As shown in Figure 2, the present embodiment is basic identical with structure and the principle of embodiment one, and different place is: be provided with spline 11b on installing hole 11 hole walls.And this spline 11b number of teeth is 30 teeth.
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.
Although this paper has more used the terms such as body 1, screw 1a, installing hole 11, keyway 11a, spline 11b, locating hole 12, cutter head 2, screw 2a, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
