Description
Technical field
The present invention relates to a kind of mining bucket tooth, one kind is used to be arranged on coal mining machinery, for coal petrography cutting
Mining bucket tooth, belong to coal mining machinery field of engineering technology.
Background technology
Mining bucket tooth is one of consumable accessory in coal mining and tunnelling machinery, is the main tool of coal breakage and broken coal, it
Performance quality to directly affect the performance of coal-cutting machinery production capacity, the consumption of power, work smoothness related to other zero
The service life of part.
Existing mining bucket tooth, is mainly made up of, carbide bit is embedded in bucket tooth bucket tooth body and carbide bit
In the shrinkage pool of body cephalic par, and it is fixedly connected by soldering.Because the head carbide bit of mining bucket tooth plays Coal Exploitation
Pick acts on, and anti-wear performance is good, so as to play certain wear-resisting digging effect, improves the service life of bucket tooth；But conduct
Mining bucket tooth product, it is that whole bucket tooth is stretched into the layer of colliery in specific mining process, head carbide bit therein
Play and rotate outside progradation forward, whole bucket tooth body, bucket tooth body that is especially close and installing the carbide bit
Leading section is also more or less by the power friction of ore-rock layer, and carbon high strength alloy steel is through adjusting in typically being used due to bucket tooth body
Matter processing forms, and its hardness and intensity are far below the carbide bit that head is inlayed, and cause bucket tooth body in the course of work
In wear in advance, so as to influence the service life of whole mining bucket tooth.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of simple and reasonable for structure, user
Just, the wearability of product surface can be increased, intensity is big, fastness is high, can improve the mining bucket of product service life and service efficiency
Tooth.
The purpose of the present invention is completed by following technical solution, a kind of mining bucket tooth, and it includes use empty in one
In the triangular pyramidal body of socket bucket tooth seat, the cone head of the triangular pyramidal body entirely surrounds the graininess that heap is welded into
Hard alloy layer, the evagination grafting block among each base is picked out on four bases of triangular pyramidal body respectively；
It is separately provided for fixing the positioning through hole of bucket tooth seat on the triangular symmetry side of the triangular pyramidal body.
As preferred：The ladder anchor ring of at least twice evagination is provided with the external wall of upper portion face of the triangular pyramidal body,
Under conical surface centre position, the graininess hard alloy layer at ladder anchor ring before and after the triangular pyramidal body
Side is respectively arranged with raised square, and a vertically arranged collar is wherein connected on the raised square of side；The triangular pyramidal
The cone head of body is the long narrow bar end face covered with the graininess hard alloy layer.
As preferred：Raised square surface above the collar also has from graininess hard alloy layer lower edge above
Fritter graininess hard alloy layer；The triangular symmetry side of the triangular pyramidal body is located at the side of positioning through hole two difference
Be provided be connected to from above ladder anchor ring, under connect a fritter arc notch face of outer side edges, face base below positioning through hole
Middle evagination grafting block.
The invention belongs to prior art one kind improve, have it is simple and reasonable for structure, it is easy to use, product can be increased
The wearability on surface, intensity is big, fastness is high, the features such as improving product service life and service efficiency.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1-4, a kind of mining bucket of the present invention
Tooth, it includes the triangular pyramidal body 1 for being used to be socketed bucket tooth seat empty in one, and the cone head 2 of the triangular pyramidal body 1 is whole
The individual graininess hard alloy layer 3 for surrounding heap and being welded into, pick out on four bases 4 of triangular pyramidal body 1 and be located at respectively
Evagination grafting block 5 among each base；It is separately provided on the triangular symmetry side 6 of the triangular pyramidal body 1
The positioning through hole 7 of fixed bucket tooth seat.
Shown in figure, the ladder anchor ring of at least twice evagination is provided with the external wall of upper portion face of the triangular pyramidal body 1
8, the centre position of conical surface 9, the graininess hard alloy at ladder anchor ring 8 before and after the triangular pyramidal body 1
Layer 3 has been respectively arranged below raised square 10, and a vertically arranged collar 11 is wherein connected on the raised square 10 of side；
The cone head 2 of the triangular pyramidal body 1 is the long narrow bar end face 12 covered with the graininess hard alloy layer 3.
The surface of raised square 10 of the top of the collar 11 of the present invention also has from the lower edge of graininess hard alloy layer 3 above
Fritter graininess hard alloy layer 13；The triangular symmetry side 6 of the triangular pyramidal body 1 is located at 7 liang of positioning through hole
Side be respectively arranged be connected to from above ladder anchor ring 8, under connect a fritter arc notch face 14 of outer side edges, under positioning through hole 7
The upright evagination grafting block 5 against among base.
The present invention sets graininess hard alloy layer using on bucket tooth head, greatly strengthen the wearability of product, carries
High service life；Inner triangular taper hollow part can realize the fine cooperation of somersault toothholder, and the through hole of the left and right sides is favourable
In positioning and fix.
