Description

Mining bucket tooth

Technical field

The utility model relates to a kind of mining bucket tooth, one kind being used for cutting for being mounted on coal mining machinery The mining bucket tooth of coal petrography, belongs to coal mining machinery field of engineering technology.

Background technology

Mining bucket tooth is one of the vulnerable part 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 zero related to other The service life of part.

Existing mining bucket tooth, is mainly made of bucket tooth body and carbide bit, carbide bit is embedded in bucket tooth In the shrinkage pool of body cephalic par, and it is fixedly connected by soldering.Since the head carbide bit of mining bucket tooth plays Coal Exploitation Pick acts on, and wear-resisting property is good, so as to play certain wear-resisting digging effect, improves the service life of bucket tooth；But conduct Mining bucket tooth product is that entire bucket tooth stretches into coal mine layer in specific mining process, head carbide bit therein It plays and rotates except progradation forward, entire bucket tooth body, bucket tooth body that is especially close and installing the carbide bit Front end is also more or less by the power friction of ore-rock layer, and carbon high strength alloy steel is through adjusting in generally being used due to bucket tooth body Matter processing forms, and hardness and strength are far below the carbide bit that head is inlayed, and cause bucket tooth body in the course of work In wear in advance, to influence the service life of entire mining bucket tooth.

Invention content

The purpose of the utility model is to overcome the shortcomings of the prior art, and offer is a kind of simple and reasonable for structure, makes With conveniently, the wearability of product surface can be increased, intensity is big, fastness is high, can improve the mine of product service life and service efficiency Use bucket tooth.

The purpose of this utility model is completed by following technical solution, a kind of mining bucket tooth, it includes empty in one For being socketed the triangular pyramidal body of bucket tooth seat, the cone head of the triangular pyramidal body entirely surrounds that heap is welded into Granular carbide layer picks out the evagination grafting among each bottom edge on four bottom edges of triangular pyramidal body respectively Block；The positioning through hole of fixed bucket tooth seat is separately provided on the triangular symmetry side of the triangular pyramidal body.

As preferred：The ladder anchor ring of at least twice evagination is provided on 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, is wherein connected to a vertically arranged lantern ring on the raised square of side；The triangular pyramidal The cone head of body is long narrow end face for being covered with the graininess hard alloy layer.

As preferred：Raised square surface above the lantern ring 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 positioning through hole two sides difference Be provided be connected to from above ladder anchor ring, under connect a fritter arc notch face of outer side edges, face bottom edge below positioning through hole Intermediate evagination grafting block.

The utility model belongs to a kind of improvement to the prior art, have it is simple and reasonable for structure, it is easy to use, can increase The wearability of product surface, intensity is big, fastness is high, the features such as capable of improving product service life and service efficiency.

Specific implementation mode

The utility model is described in detail below in conjunction with attached drawing：Shown in Fig. 1-4, one kind described in the utility model Mining bucket tooth, it includes the empty triangular pyramidal body 1 for being socketed bucket tooth seat in one, the cone of the triangular pyramidal body 1 Head 2 entirely surrounds the graininess hard alloy layer 3 that heap is welded into, and is picked out respectively on four bottom edges 4 of triangular pyramidal body 1 There is the evagination grafting block 5 among each bottom edge；It is respectively set on the triangular symmetry side 6 of the triangular pyramidal body 1 It is useful for the positioning through hole 7 of fixed bucket tooth seat.

As shown in the figure, the ladder anchor ring of at least twice evagination is provided on the external wall of upper portion face of the triangular pyramidal body 1 8,9 centre position of conical surface, 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, is wherein connected to a vertically arranged lantern ring 11 on the raised square 10 of side； The cone head 2 of the triangular pyramidal body 1 is long narrow end face 12 for being covered with the graininess hard alloy layer 3.

10 surface of raised square of 11 top of lantern ring described in the utility model also has from graininess hard alloy layer 3 above The fritter graininess hard alloy layer 13 of lower edge；The triangular symmetry side 6 of the triangular pyramidal body 1 is located at positioning through hole 7 two sides be respectively arranged be connected to from above ladder anchor ring 8, under connect a fritter arc notch face 14 of outer side edges, positioning through hole 7 Lower section faces the evagination grafting block 5 among bottom edge.

The utility model uses is arranged graininess hard alloy layer on bucket tooth head, greatly strengthens the wear-resisting of product Property, improve service life；Inner triangular taper hollow part can realize the fine cooperation of somersault toothholder, the through-hole of the left and right sides Be conducive to position and fix.
