Abstract

A kind of tooth of stone crusher, it includes a block tooth body, the tooth head that side end is provided with wedge angle type is located on the top working face of the tooth body, described tooth head bulk hard alloy is embedded on working face and is constituted in the scarfing slot of side end, and overall heap is welded with one layer of broken alloy solder layer of hard on the inward facing surface of the tooth head;The side that the bottom of the tooth body corresponds to tooth head is provided with convex projection or projection under vertical configuration, and medial surface and the lower flat in the projection or projection form fitting surface with toothholder corresponding position, separately the middle setting in the lower flat has not insertion, location hole perpendicular to lower flat;A cone head raised obliquely, and the broken alloy solder layer of hard being higher by working face above the tooth head are formed in the middle of described tooth head;It has rational in infrastructure, and easy to install and use, overall tooth header structure fastness is good, wear-resisting, so that the features such as improving operating efficiency.

Description

A kind of tooth of stone crusher
Technical field
The utility model relates to a kind of tooth of stone crusher, belong to mining machinery equipment technical field.
Background technology
Mining industry stone crusher is a kind of common mining disintegrating apparatus, is generally used for the primary comminution of ore.Existing mining industry The tooth of stone crusher by with drive it is pivotally connected after, collision type contact is carried out to ore at work, so as to ore be smashed; But existing stone crusher tooth is made of Hardmetal materials, under the shock and vibration of ore, teeth portion is impacted and easily damage It is bad, it is even using Hardmetal materials etc. but not reasonable because of structure design in the working head of tooth, easily cause teeth portion Clashed into by ore, caused whole teeth portion structural damage, it is necessary to often change tooth head, so as to influence operating efficiency, increase makes Use cost.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of rational in infrastructure, uses peace Dress is convenient, and overall teeth portion structural integrity is good, wear-resisting, improves the tooth of the stone crusher of operating efficiency.
The purpose of this utility model is addressed by following technical proposals:A kind of tooth of stone crusher, it includes one Block tooth body, is located at the tooth head that side end is provided with wedge angle type, described tooth head on the top working face of the tooth body Portion's bulk hard alloy is embedded on working face and is constituted in the scarfing slot of side end, and in the inner side of the tooth head Overall heap is welded with one layer of broken alloy solder layer of hard on working face;The side that the bottom of the tooth body corresponds to tooth head is set There is a convex projection or projection under vertical configuration, and medial surface in the projection or projection forms with toothholder corresponding portion with lower flat The fitting surface of position, separately the middle setting in the lower flat have not insertion, location hole perpendicular to lower flat.
As preferred:Form a cone head raised obliquely in the middle of described tooth head, and the tooth head is upper The broken alloy solder layer of hard that face is higher by working face;The both sides middle side part of tooth body is each provided with the cascaded surface of an evagination, and edge And up-small and down-big tooth body is formed down outside cascaded surface, separately the middle setting in the lower flat of the tooth body has outer Convex cylinder, and middle setting in the cylinder has described location hole, the evagination of the cylinder is highly less than described in The bottom surface of projection or projection.
The utility model is improvements over the prior art, and it has rational in infrastructure, easy to install and use, overall tooth header structure Fastness is good, wear-resisting, so that the features such as improving operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A direction views of Fig. 1.
Fig. 3 is the B direction views of Fig. 1.
Fig. 4 is the C direction views of Fig. 1.
Specific embodiment
The utility model is described in detail below in conjunction with accompanying drawing:Shown in Fig. 1-4, one kind described in the utility model The tooth of stone crusher, it includes a block tooth body 1, side end is provided with wedge angle on the top working face 2 of the tooth body 1 The tooth head 3 of type, described tooth head 3 is embedded on working face the structure in the scarfing slot of side end with bulk hard alloy Into, and overall heap is welded with one layer of broken alloy solder layer 4 of hard on the inward facing surface 2 of the tooth head 3;The tooth body 1 The side that bottom corresponds to tooth head 3 is provided with convex projection or projection 5 under vertical configuration, and in the projection or projection 5 Medial surface 6 forms the fitting surface with toothholder corresponding position with lower flat 7, and separately the middle setting in the lower flat 7 has not Insertion, location hole 8 perpendicular to lower flat 7.
Form a cone head 9 raised obliquely in the middle of described tooth head 3, and it is 10 high above the tooth head 3 The broken alloy solder layer 4 of hard gone out on working face;The both sides middle side part of tooth body 1 is each provided with the cascaded surface 11 of an evagination, and edge The outside for cascaded surface 11 is formed down up-small and down-big tooth body 1, separately the tooth body 1 lower flat middle setting There is a cylinder 12 of evagination, and middle setting in the cylinder 12 has described location hole 8, the evagination of the cylinder 12 is high Degree is less than the projection or the bottom surface of projection 5.
The utility model increases anti-wear performance in its big bulk alloy of tooth head 3, it is adaptable in hard, superhard work Face;Using the built-up welding of large area on the working face of top, the wearability of working face is increased, substantially prolongs the service life of tooth.
