Abstract
The utility model relates to a technical proposal for a grass cutting machine. The utility model solves the defects that a knife blade of a moving knife of the existing grass cutting machine is only provided with an effective working position, the replacement procedure of the knife blade delays farming season easily after worn, etc. The utility model is characterized in that the existing single blade knife blade structure is replaced by the more blades structure of the knife blade of the moving knife. The utility model can effectively prolong the working time of the knife blade of the moving knife, and can be convenient to cut grass for users.
Description
Technical field
The utility model relates to forage by the employed hay cutter device of coarse crushing, in particular the architecture advances of hay cutter moving knife part.
Background technology
The hay cutter key is to utilize the disc type moving knife of high speed rotating and stationary knife acting in conjunction to form shearing active force moment with the disconnected cutting section of the shaft-like forage of bar, makes roughage.Existing disc type hay cutter, the composition structure of its moving knife part is that the single dege blade of several (being generally four) trapezoidal shape removably is fixed on the disc type moving knife knife rest substantially, the hay cutter of this moving knife version, the blade that its moving knife blade one experience wear just must more renew, or grind the cutter peak again, not only wasted the raw material that blade is made, and when not having standby new blade for the moment, the process that perhaps grinds the cutter peak then can delay valuable farming season.So existing hay cutter is aspect the wearing and tearing and replacing of blade, the structural design of its moving knife part is also imperfect.
Summary of the invention
Existing disc type hay cutter is under the situation of overall structure form basic fixed, the influence of the easiest the most serious frayed grass cutter sheet of its working condition, by the elaboration partly of above-mentioned background technology as can be known, because the moving knife blade of existing hay cutter is single dege blade, its wearing and tearing are the fastest, need often to change, existing hay cutter is considered very shortcoming for blade because of the technical elements that quick wearing and tearing need to change, and the replacing of blade causes waste of raw materials again.For solving above-mentioned technology disadvantage, the utility model proposes a kind of technical scheme of multiple-cutting-edge moving knife hay cutter, this technical scheme is to the effect that: the moving knife in this hay cutter partly includes the disc type knife rest in the rotating shaft and is removably fixed in moving knife blade on this knife rest, the major technique characteristics of the technical program are that its moving knife blade is a throw-away tip, and promptly at least two of its moving knife blade hand hay cutter limits are shaped on blade.
The hay cutter that the utility model is designed, the hilted broadsword moving knife insert design that its technical scheme will have hay cutter moving knife part now becomes after the throw-away tip structure, just can make its each blade can bring into play the effect of a plurality of blades, during the machine operation, be in the moving knife blade rotation work of shearing work position with the stationary knife blade, the blade of other side then is in the diastema wait state, after the service wear of working position blade, just can soon this blade be in and treat that a state moving knife blade rotation mount is to working position, this design makes more changing jobs of blade become more convenient, makes this hay cutter enter normal operating conditions in the shortest time.
Description of drawings
Fig. 1 is the axial arrangement view that the moving knife part one of this hay cutter is implemented structure
Fig. 2 is the axial arrangement view of another enforcement structure of this hay cutter moving knife part
Fig. 3 for the A of Fig. 1 or Fig. 2 to match with the stationary knife topology view of work of main partial structurtes.
Embodiment
The structure of moving knife in disc type hay cutter part is formed and is included the moving knife cutterhead 1 that rotates with rotating shaft and be fixed in moving knife blade on this cutterhead 1 by screw and nut 3 or dismounting, and its moving knife blade is a throw-away tip.In embodiment as figure, specifically provided the structure implemented of two kinds of multiple-cutting-edge moving knife blades, as shown in Figure 1, side 20a, the 20b of inswept stationary knife blade 4 blades are shaped on cutter honeybee blade in opposite directions on its moving knife blade 2, in the present embodiment, rising of its cutter peak is domatic 21,22 all oblique to moving knife cutterhead 1 in, promptly is shaped on the blade that is centrosymmetric on the side of this moving knife blade 2, be convenient to blade and directly rotate an angle and just can finish and change the sword operation, the assembly performance that the moving knife blade is commutated is good.When wherein a moving knife blade 20b was in working position, then another moving knife blade 20a then was in a reverse state for the treatment of.This moving knife blade 2 can alternately change its both sides blade to working position, so the effective length of the blade of its both sides preferably equates.Fig. 2 has provided its another kind of embodiment, promptly its moving knife blade be triangular blade 2 ', its each side all is shaped on blade, when wherein a side blade 20b ' was in working position, the blade of other dual-side then was in the diastema wait state; The effective length of the blade of its each side preferably equates.
Claims (6)
1, a kind of hay cutter, moving knife wherein partly include the disc type cutterhead (1) in the rotating shaft and are removably fixed in moving knife blade on this cutterhead, it is characterized in that its moving knife blade is a throw-away tip, and at least two hand hay cutter limits of its moving knife blade are shaped on blade.
2, hay cutter according to claim 1 is characterized in that being shaped on the blade that is centrosymmetric on the side of this moving knife blade.
3, hay cutter according to claim 1 and 2 is characterized in that the side of the inswept stationary knife blade of moving knife blade (2) is shaped on sword peak blade in opposite directions.
4, hay cutter according to claim 3 is characterized in that the cutter peak of moving knife blade (2) is domatic all oblique in cutterhead (1).
5, hay cutter according to claim 1 is characterized in that the moving knife blade is triangular blade (2 '), and its each side all is shaped on blade.
6, hay cutter according to claim 5 is characterized in that the blade effective length of each side of moving knife blade (2) equates.
