Description
Technical field
The utility model relates to agricultural mechanical field, particularly a kind of cutter of crop straw crusher.
Background technology
The comprehensive utilization of agricultural crop straw mainly contains 5 kinds of approach: one is as agrochemical fertilizer, and two is as feed, and three is as the rural novel energy, and four is as the raw material of industry, and five is as base-material.
In order to play the effect of fresh crops straw as feed better, need fresh crops straw to pulverize making beating in advance.But lack the machinery carrying out pulverizing making beating for fresh crops straw at present.The machinery in the past pulverized for dry crops straw is not suitable for the pulverizing making beating of fresh crops straw.
Utility model content
For solving the problems of the technologies described above, it is simple, easy to use that the purpose of this utility model is to provide a kind of structure, fast fresh crops straw can be pulverized the cutter of the crop straw crusher of making beating.
For achieving the above object, the cutter of a kind of crop straw crusher of the utility model, the cutter of described crop straw crusher comprises cutter shaft, the screw blade that is arranged on the cutter on described cutter shaft top, is arranged on bottom knife in the middle part of described cutter shaft, is arranged on described cutter shaft bottom;
Described cutter is symmetrical triangular pyramidal blade, and described triangular pyramidal blade is the blade of monolateral one-side band sword;
Described cutter and described cutter shaft center line are that 25o-28o is arranged;
Described cutter and described bottom knife are spaced from each other and are not in contact with each other;
Described bottom knife is the yi word pattern blade arranged in a crossed manner with described cutter, and described bottom knife knife face is provided with cutter tooth;
Described bottom knife is butterfly, and two ends tilt upward and are provided with chopping blade, and the angle of described chopping blade and described cutter shaft axis is 45o-65o, and described chopping blade two ends are symmetrically arranged with curved blade.
On the basis of such scheme preferably, described cutter tooth is arranged on the upper surface of described bottom knife.
On the basis of such scheme preferably, described cutter tooth is arranged on the lower surface of described bottom knife.
On the basis of such scheme preferably, described cutter tooth is arranged on upper surface and the lower surface of described bottom knife simultaneously.
On the basis of such scheme preferably, described cutter is also provided with cutter tooth.
The utility model compared with prior art, its beneficial effect is: structure is simple, easy to use, fast fresh crops straw can be pulverized making beating, fresh crops straw is after the utility model process, finer and smoother, be suitable as very much feed to use, improve the availability of fresh crops straw resource.
Accompanying drawing explanation
Fig. 1 is the cutter structure schematic diagram of the crop straw crusher of the utility model embodiment;
Fig. 2 is the bottom blade form schematic diagram of the utility model embodiment.
Embodiment
By describe in detail the utility model technology contents, structural feature, reached object and effect, hereby exemplify embodiment below and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, and combination is consulted shown in Fig. 1 to Fig. 2, the utility model provides a kind of cutter of crop straw crusher, the screw blade 40 comprising cutter shaft 30, be arranged on the cutter 10 on cutter shaft 30 top, be arranged on bottom knife 20 in the middle part of cutter shaft 30, be arranged on cutter shaft 30 bottom.
Described cutter 10 is symmetrical triangular pyramidal blade, and described bottom knife 20 is the yi word pattern blade arranged in a crossed manner with this cutter 10, and the knife face of bottom knife 20 is provided with cutter tooth 21.
During work, cutter shaft 30 rotates, and drive cutter 10, bottom knife 20 and screw blade 40 rotate, fresh crops straw tentatively shreds by the triangular pyramidal blade of cutter 10, fresh crops straw sinks, drop on bottom knife 20, cutter tooth 21 on bottom knife 20, screw blade 40 shreds further, because cutter tooth 21 cutting output is little and cutter shaft 30 drives bottom knife to rotate, add fresh crops straw and bottom knife 20 and on the probability that contacts of cutter tooth 21, make fresh crops straw by bottom knife 20 and on cutter tooth 21 cut more broken, thus make to process the finer and smoother of fresh crops straw.
In order to ensure the probability that fresh crops straw and cutter 10 and bottom knife 20 collide further, be spaced from each other between cutter 10 of the present utility model and bottom knife 20 and be not in contact with each other, during stirring, cutter 10, bottom knife 20 and screw blade 40 rotate with cutter shaft, and form upper, middle and lower eddy current in the upper, middle and lower respectively, upper, middle and lower eddy current rotate make fresh crops straw and cutter 10, bottom knife 20, screw blade 40 collision more frequent, thus it is more thorough to make fresh crops straw shatter, particle is more even.
Please continue to refer to Fig. 2, the preferred butterfly of shape of this bottom knife 20, its two ends tilt upward and are provided with chopping blade 22, and are 45o-65o with the angle of cutter shaft 30 axis, and chopping blade 22 two ends are symmetrically arranged with curved blade 23.
Preferred as one of the present utility model, described cutter tooth is arranged on the upper surface of described bottom knife 20.
Preferred as one of the present utility model, described cutter tooth is arranged on the lower surface of described bottom knife 20.
Preferred as one of the present utility model, described cutter tooth 21 is arranged on upper surface and the lower surface of described bottom knife 20 simultaneously.
Preferred as one of the present utility model, it is not shown that described cutter 10 is provided with cutter tooth 21().
In order to guarantee that fresh crops straw can fully shred further, described cutter 10 is the blade of monolateral one-side band sword.
Preferred as one of the present utility model, described triangular pyramidal cutter and described cutter shaft 30 center line are 25o-28o.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalence changes done according to the utility model the scope of the claims and description with modify, be all within scope that the utility model patent contains.
