Embodiment
Embodiment one:
See Fig. 1, the anti-autogenous grinding tool rest of a kind of straw cutting apparatus, comprise a pair tool rest 1, bearing pin 2, the top of described a pair tool rest is provided with axis hole 3, and described bearing pin is installed in described axis hole, is provided with special-shaped counterbore 4 in the outside of described axis hole; One end of described bearing pin is provided with special-shaped boss 5, and described special-shaped boss and described special-shaped counterbore match.
See Fig. 5, same as the prior art, the other end of described bearing pin is provided with pad and split pin 11.
Further, described tool rest is made up of steel plate, be circular arc bottom described tool rest, curvature bottom described tool rest is identical with the curvature of straw cutting apparatus rotating shaft, accurate positioning when facilitating workman to be welded and fixed, ensure the quality of welding, described tool rest being weldingly fixed on field-returning machine rotating shaft 10 along helix rule.
In the present embodiment, the structure of described a pair tool rest 1 is identical, and described bearing pin 2 inserts in the special-shaped counterbore 4 of one of them tool rest, and described pad and split pin are installed in the special-shaped counterbore of another tool rest.Described tool rest arranges special-shaped counterbore, described bearing pin is arranged special-shaped boss 5, special-shaped counterbore and special-shaped boss mating reaction, the effective rotation stoping bearing pin, reduces the degree of wear of bearing pin, tool rest.
In the present embodiment, described special-shaped counterbore is square, and described special-shaped boss is square.When bearing pin runs through a pair tool rest, the special-shaped boss of end part of pin shaft is contained in special-shaped counterbore.
Further, the other end of described bearing pin is provided with profiled spacer 7 and jump ring 8, and described profiled spacer and described special-shaped counterbore match.Jump ring is more convenient for dismantling compared with split pin, and makes the assembling between bearing pin, flail knife, tool rest compacter, and quality of fit is high, effectively prevents the mutual wearing and tearing between the axially-movable of bearing pin and each parts, does not also increase any cost.
Further, described jump ring 8 is positioned at the inner side of described special-shaped counterbore 4.Described special-shaped counterbore can play a protective role to jump ring, prevents jump ring from cutter shaft rotary course, bumping against foreign object and come off, and then causes coming off of bearing pin and flail knife, affects the whole machine balancing of harvesting effect and straw cutting apparatus.
Further, flail knife 6 is arranged on a pair tool rest by described bearing pin.First tool rest is provided with bearing pin and is suitable for, by bearing pin, two or more flail knives are installed, one end of each flail knife is pivotally mounted on bearing pin, can prevent flail knife straw cutting apparatus rotating shaft also field operation time the sharp pounding that produces under and get loose.
Further, inner sleeve 9 is provided with in the axis hole of described flail knife.Described bearing pin, through the hole of inner sleeve, owing to having set up inner sleeve between bearing pin and flail knife, has avoided the direct friction between bearing pin and flail knife, when inner sleeve serious wear, changes inner sleeve, significantly reduces the cost of renewal part.
Further, see Fig. 2 to Fig. 4, the shape of described special-shaped counterbore 4 is polygon or ellipse.Described special-shaped counterbore can be triangle, square, regular pentagon, ellipse.Accordingly, the special-shaped boss on described bearing pin is also triangle, square, regular pentagon, ellipse.
More optimize, the shape of described special-shaped counterbore can also be zigzag, and accordingly, the special-shaped boss on described bearing pin is gear shape, and this special-shaped boss is meshed with this special-shaped counterbore.This kind of structure is more effective to stoping the rotation of bearing pin, even if under strong vibrations, is also down to minimum by the degree of wear of guarantee bearing pin, tool rest.
Further, the other end of described bearing pin is provided with internal thread hole, installs fastening bolt in described internal thread hole.Prevent bearing pin transfer in order to more effective, set up internal thread hole at the other end of bearing pin, utilize fastening bolt to carry out fastening, fastening bolt end is still dropped in the special-shaped counterbore of tool rest.
Further, the other end of described bearing pin is provided with external screw thread, and the external screw thread of described bearing pin is provided with double nut.Effectively prevent the another kind of structure of bearing pin transfer from being set up external screw thread at the other end of bearing pin, utilize double nut to carry out fastening, by two nuts and tight time, can realize preventing from loosening, double nut still drops in the special-shaped counterbore of tool rest.
Embodiment two:
A kind of straw cutting apparatus, along the anti-autogenous grinding tool rest described in fixing multiple embodiments one of helix rule on the rotating shaft of described straw cutting apparatus.Described anti-autogenous grinding tool rest can delay the wearing and tearing of tool rest axis hole, reduces the cost of straw-returning operation.
The content of the present embodiment is only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
