Description
Technical field
The utility model belongs to farm equipment application, relates to harvester cutting blade particularly.
Background technology
Cutter is one of universal component important on grain header, quality the carrying out smoothly for harvest operation of its performance, reduces yield loss etc. and all has very large effect.Existing cutter blade deadweight is comparatively large, makes consumed power of whole machine in operation process larger; In addition, some the hard things owing to often touching earth's surface in operation process can make cutter tooth be destroyed, and need constantly more allowing blade replacement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of conduct oneself with dignity little, durability is high, the harvester cutting blade of cutter tooth not sensitive for damages.
Technical problem to be solved in the utility model realizes by the following technical solutions: a kind of harvester cutting blade, comprise blade body, described blade body comprises installation portion and cutting part, described cutting part is triangular in shape, base and the installation portion of cutting part are connected, the left side of cutting part and the right are respectively equipped with multiple cutter tooth, cutter tooth is extruded by steel plate plastic deformation, parallel to each other and the cutter tooth on the left side and the right of multiple cutter tooth is arranged symmetrically with relative to the center line on base, the position that the left side and the right are intersected is provided with protection department, the middle and lower part of cutting part is provided with auxiliary positioning hole, auxiliary positioning hole is triangular in shape, the middle part of installation portion is provided with lightening hole, installation portion is also provided with two installing holes, lightening hole is between two installing holes, lightening hole comprises end circular hole and middle part rectangular opening.
Preferably, described lightening hole is communicated with auxiliary positioning hole.
Preferably, described installation portion and cutting part are one-body molded.
Preferably, the length of described protection department on the base centerline direction of cutting part is 2 ~ 4mm.
Preferably, described two installing holes are arranged symmetrically with relative to the center line of installation portion.
Closer, described installing hole is screwed hole.
The beneficial effects of the utility model are: 1) by arranging lightening hole in blade body, the deadweight of blade can be reduced, and then the power consumption of complete machine in operation process can be reduced, be scattered in the impurity on blade in operation process simultaneously, dust also can leave out by mistake, to keep the clean of blade work environment from lightening hole; 2) blade is extruded by plastic deformation by steel plate, the steel density of cutter tooth can be strengthened, improve the durability of whole blade; 3) protection department is set in the front end of cutting part, does not namely do cutter tooth in cutting part front end, the intensity of front end can be strengthened, cutter tooth below can be protected not by the destruction of hard thing in operation process; 4) cutting part of blade body is designed to triangle, teeth portion crop being fed blade in the reciprocal cutting movement of blade can be beneficial to; 5) cutter tooth being designed to zigzag symmetrical, parallel to each other, making blade uniform force when cutting crop; 6) auxiliary positioning hole is set in blade body, accurate positioning can be guaranteed, connect reliably.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
In figure, 1, blade body, 2, installation portion, 3, cutting part, 4, installing hole, 5, lightening hole, 6, cutter tooth, 7, protection department, 8, auxiliary positioning hole.
Embodiment
For the technical characterstic of this programme can be clearly demonstrated, with reference to the accompanying drawings the utility model embodiment is described further below.
As shown in Figure 1, the harvester cutting blade in embodiment one of the present utility model, this blade can be arranged on gather in multiple different crops harvester cutting on.This blade comprises blade body 1, the cutting part 3 that blade body 1 comprises the installation portion 2 for being connected with cutter and gathers in crops, and particularly, installation portion 2 and cutting part 3 are one-body molded.
Cutting part 3 is designed to triangle, and its outward flange comprises base, the left side and limit, three, the right, and cutting part is designed to triangle, can be beneficial to teeth portion crop being fed blade in the reciprocal cutting movement of blade.Particularly, base and the installation portion of cutting part 3 are connected, and are respectively equipped with multiple cutter tooth 6 on the left side of cutting part 3 and the right, and cutter tooth 6 is extruded by steel plate plastic deformation, can strengthen the steel density of cutter tooth, improves the durability of whole blade; Multiple cutters tooth 6 on the left side and the right are designed to the parallel to each other and cutter tooth 6 on the left side and the right and are arranged symmetrically with relative to the center line on base, cutter tooth being designed to zigzag symmetrical, parallel to each other, making blade uniform force when cutting crop.
The position of intersecting on the front end place of cutting part 3 i.e. the left side of cutting part 3 and the right is provided with protection department 7, namely reserve a part in the front end of cutting part 3 and do not do cutter tooth 6, its reason is the intensity that can strengthen cutting part front end, cutter tooth below can be protected not by the destruction of hard thing in operation process, particularly, the length of this protection department 7 on the base centerline direction of cutting part 3 is 2 ~ 4mm; Be provided with auxiliary positioning hole 8 in the middle and lower part of cutting part 3, this auxiliary positioning hole 8 is designed to triangle, and bolt is connected with knife rest through auxiliary positioning hole 8, can guarantee accurate positioning, connect reliably.
Lightening hole 5 is provided with at the middle part of installation portion 2, this lightening hole can reduce the deadweight of blade, and then the power consumption of complete machine in operation process can be reduced, be scattered in the impurity on blade in operation process simultaneously, dust also can leave out by mistake from lightening hole, to keep the clean of blade work environment, particularly, lightening hole 5 comprises end circular hole and middle part rectangular opening; Installation portion 2 is also provided with two installing holes 4, lightening hole 5 is between two installing holes 4, and particularly, two installing holes 4 are arranged symmetrically with relative to the center line of installation portion 2 and installing hole 4 is screwed holes, and bolt is connected with knife rest by installing hole 4.
As shown in Figure 2, in embodiment two of the present utility model, lightening hole 5 is communicated with auxiliary positioning hole 8, and to facilitate processing, all the other are with embodiment one.
