Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of cut-out knife bar one of the present utility model preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of cut-out knife bar, comprise: knife bar bottom 1 and the knife bar top be fixedly connected with on it, the front on described knife bar top is provided with first supporting surface 21, described first supporting surface 21 is provided with the first cell body 3 and the second cell body 4, knife bar upper part is divided into the second supporting surface 22 and the 3rd supporting surface 23 by described first cell body 3, knife bar upper part is divided into the 4th supporting surface 24 and the 5th supporting surface 25 by described second cell body 4, described 4th supporting surface 24 is provided with a groove 26, described groove 26 is provided with trapezoid cross section structure, described trapezoidal be the geometric half of regular hexagon, described groove 26 forms a breach started for inner hexagon spanner together with the 5th supporting surface 25, according to the needs of actual production, equilateral polygon section structure is arranged in knife bar bottom 1, in the present embodiment, square cross-sectional configuration is arranged in knife bar bottom 1.
As shown in Figure 1, first cell body 3 is used for fixturing blade, namely fixturing blade is carried out by the second supporting surface 22 and the 3rd supporting surface 23, when blade is installed, first be placed between groove 26 and the 5th supporting surface 25 with inner hexagon spanner, prize the 5th supporting surface 25 a little, such 5th supporting surface 25 can drive the 3rd supporting surface 23 outwards to deform together, thus make the width of the first cell body 3 become large, be beneficial to installation blade like this, after blade installation, inner hexagon spanner can be taken down, 5th supporting surface 25 and the 3rd supporting surface 23 recoverable force, like this can according to the distance of little as far as possible control second supporting surface 22 of the thickness of blade and the 3rd supporting surface 23, thus ensure can not shake when blade work, stationarity is good, this structure effectively prevents from shaking during blade work, make the stability under working conditions of blade good, result of use is good, and because blade can not shake, also make the second supporting surface 22 and the 3rd supporting surface 23 that wearing and tearing occur little, the service life of effective prolongation knife bar.
Also be provided with a housing pin 6 in described groove 26, described housing pin 6 is connected on described 4th supporting surface 24 and the 5th supporting surface 25.Can be finely tuned the distance of the 4th supporting surface 24 and the 5th supporting surface 25 by housing pin 6 like this, make the installation and removal of blade more convenient, fast.
The bottom of described second supporting surface 22 and described 3rd supporting surface 23 is all provided with a rounding 27; under rounding 27 can ensure that blade in working order; certain space is left between the bottom of blade and the first cell body 3; blade can not be hurt in blade work process; particularly there is protruding blade for end, can effectively protect blade not to be worn.
Described second supporting surface 22 and the 3rd supporting surface 23 are all provided with a semi-cylindrical hill 28, the central axis of described semi-cylindrical hill 28 parallels with the first supporting surface 21, semi-cylindrical hill 28 is used for matching with the side grooves of blade, thus better stablize blade, to blade location, shake under preventing blade work state or move.
The below of the bottom of described second cell body 4 is also provided with a circular arc through hole 5, and the internal diameter of described circular arc through hole 5 is greater than the width of described second cell body 4.When installing blade, first be placed between groove 26 and the 5th supporting surface 25 with inner hexagon spanner, prize the 5th supporting surface 25 a little, when blade descends in working order, blade also has active force and acts on the second cell body 4, now, circular arc through hole 5 can effectively prevent the bottom of the second cell body 4 from ftractureing.
The reverse side on described knife bar top is provided with a boss, to increase the rigidity on knife bar top, and the vibrations of knife bar under minimizing blade work state.
The width of described first cell body 3 is greater than the width of described second cell body 4, and the height of described first cell body 3 is greater than the height of described second cell body 4.
Be different from prior art, the utility model cut off that lever structure is simple, blade easy installation and removal quick, decrease blade work state under vibrations, the wearing and tearing effectively reducing knife bar, the service life extending knife bar, good stability, result of use better.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
