Abstract
The invention discloses a cutting tooth. The cutting tooth comprises a first tooth head, a tooth shoulder and a tooth handle, wherein the first tooth head is provided with a sharp corner breaking part and is arranged in the middle of a second tooth head with a U-shaped structure; broken sharp corners are arranged at the positions, on two sides of the first tooth head, of the upper end of the second tooth head; the outer side of the second tooth head is subjected to circular arc transition from the tooth shoulder to the broken sharp corners; a joint between the second tooth head and the first tooth head is subjected to circular arc transition; a plurality of damping bodies are arranged inside the tooth handle in parallel. The cutting tooth is simple in structure and reasonable in design; certain cutting force can be ensured; meanwhile, the area of cutting each time can be increased, and the excavating efficiency is improved; by virtue of the damping bodies, the strength of the tooth handle is ensured, the effects of shock absorption and noise reduction can be effectively achieved, the vibration damage to equipment is effectively reduced, and an operator feels better.
Description
Technical field
The present invention relates to coal mining machinery technical field, relate in particular to a kind of cut tooth.
Background technology
At present, the tooth head of mining cut tooth and denticle be all conventionally welding or make all-in-one-piece, and conventional tooth head mostly is pyramidal structure, but this structure although to grind power large, but grinding surface is little, simultaneously the denticle of cut tooth generally is cylindrical steel structure, and tooth head produces during cut like this vibration and noise all can cause bad impact to equipment, operating personnel.Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Summary of the invention
Technical problem for above-mentioned existence, the object of the invention is: proposed a kind of cut tooth.
Technical solution of the present invention is achieved in that a kind of cut tooth, comprise the first tooth head, tooth shoulder and tooth handle, described the first tooth head is provided with wedge angle fragmentation portion, described the first tooth head is arranged on the second tooth head centre position of the structure that takes the shape of the letter U, described the second tooth head upper end is positioned at the first tooth head both sides and is provided with broken wedge angle, and the outside of the second tooth head is from tooth shoulder to broken sharp corner arc transition, the junction of described the second tooth head and the first tooth head is arc-shaped transition, and the inside of described tooth handle is provided with several shock reducing structures that are arranged in parallel.
As preferably, described the first tooth head and the second tooth are first body formed.
As preferably, described shock reducing structure is cylindrical structure.
As preferably, described shock reducing structure is that elastomeric material is made.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Cut tooth of the present invention, simple in structure, reasonable in design, the present invention can also increase the area of cut each time when guaranteeing certain clipping force, improves the efficiency of driving, shock reducing structure is set simultaneously, when guaranteeing tooth handle intensity, can effectively play the effect of shock-absorbing, noise reduction, effectively reduced the vibration damage of equipment and allowed the feeling all right of operating personnel.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A to view.
In figure: 1. the first tooth head; 2. tooth handle; 3. tooth is takeed on; 4. the second tooth head; 5. shock reducing structure.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Refer to Fig. 1 and Fig. 2, a cut tooth, comprises the first tooth head 1, tooth shoulder 3 and tooth handle 2, and described the first tooth head 1 is provided with wedge angle fragmentation portion, described the first tooth head 1 is arranged on the second tooth head 4 centre positions of the structure that takes the shape of the letter U, and described the first tooth head 1 and the second tooth head 4 are one-body molded.Described the second tooth head 4 upper ends are positioned at the first tooth head 1 both sides and are provided with broken wedge angle, can guarantee the cutting capacity of this cut tooth like this, and the outside of the second tooth head 4 is from tooth shoulder 3 to broken sharp corner arc transition, can prevent that like this this cut tooth generation stress is concentrated in equipment cutting course, thereby extend the application life of cut tooth.The junction of described the second tooth head 4 and the first tooth head 1 is arc-shaped transition, the inside of described tooth handle 2 is provided with several shock reducing structures 5 that are arranged in parallel, described shock reducing structure 5 is cylindrical structure, and described shock reducing structure 5 is made for elastomeric material, the vibrations that produce in the time of can effectively absorbing cut like this.This cut tooth can be when guaranteeing certain clipping force, the first tooth head 1 and the second tooth head 4 on it increase the area of cut each time, improve the efficiency of driving, while shock reducing structure 5, when guaranteeing tooth handle 2 intensity, can effectively play the effect of shock-absorbing, noise reduction, effectively reduced the vibrations damage of equipment and allowed the feeling all right of operating personnel.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
