Abstract
A kind of mining pick, it is mainly integrally made up of cylindrical knife shank and cone bit body, and described bit body front-end-cone angle head is provided with multiple equally distributed deep holes, and column shaped carbide alloy and firm welding are inlaid with the deep hole；Using double-deck broken alloy welding deposit technology formed with graininess hard alloy layer on the conical outer wall face of the bit body；Annular groove is provided with described cylindrical knife shank, positioned at outer end, and forms the discoideus bottom seat in outside；Formed with a transition taper slope for being easy to positioning between described annular groove and upper cylindrical handle of a knife；Graininess hard alloy layer on the bit body is covered with the conical outer wall face of whole cone, the bottom of the cone is also integrally formed with one narrow section of transition connecting cylinder body, and described cylindrical knife shank is integrally mutually connected among the outboard end of the connecting cylinder body；It has it is simple and reasonable for structure, it is easy to use, the wearability of product surface can be increased, intensity is big, fastness is high, the features such as improving product service life and service efficiency.
Description
Technical field
The utility model relates to a kind of mining pick, one kind is used to be arranged on coal mining machinery, for cut
The mining pick of coal petrography, belong to coal mining machinery field of engineering technology.
Background technology
Mining pick 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 pick, mainly it is made up of pick body and carbide bit, carbide bit is embedded in pick
In the shrinkage pool of body cephalic par, and it is fixedly connected by soldering.Because the head carbide bit of mining pick 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 pick；But conduct
Mining pick product, it is that whole pick is stretched into the layer of colliery in specific mining process, head carbide bit therein
Play and rotate outside progradation forward, whole pick body, pick 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 pick body
Matter processing forms, and its hardness and intensity are far below the carbide bit that head is inlayed, and cause pick body in the course of work
In wear in advance, so as to influence the service life of whole mining pick.
The content of the invention
The purpose of this 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 ore deposit of product service life and service efficiency
Use pick.
The purpose of this utility model is completed by following technical solution, and a kind of described mining pick, it is main
Integrally it is made up of cylindrical knife shank and cone bit body, described bit body front-end-cone angle head is provided with multiple uniform
The deep hole of distribution, and column shaped carbide alloy and firm welding are inlaid with the deep hole；The conical outer wall of the bit body
Using double-deck broken alloy welding deposit technology formed with graininess hard alloy layer on face.
As preferred：Annular groove is provided with described cylindrical knife shank, positioned at outer end, and forms the plectane in outside
Shape bottom seat；Formed with a transition taper slope for being easy to positioning between described annular groove and upper cylindrical handle of a knife；It is described
Graininess hard alloy layer on bit body is covered with the conical outer wall face of whole cone, the bottom also one of the cone
System has one narrow section of transition connecting cylinder body, and described cylindrical knife shank is integrally mutually connected on the outboard end of the connecting cylinder body
It is middle.
The utility model belong to prior art one kind improve, 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 improving product service life and service efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is Fig. 1 B direction views.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing：Shown in Fig. 1-3, one kind described in the utility model
Mining pick, it is mainly integrally made up of cylindrical knife shank 1 and cone bit body 2, the described front end cone angle of bit body 2
Head 10 is provided with multiple equally distributed deep holes 3, and column shaped carbide alloy 4 and firm welding are inlaid with the deep hole 3；
Using double-deck broken alloy welding deposit technology formed with graininess hard alloy layer 5 on the conical outer wall face of the bit body 2.
Shown in figure, on described cylindrical knife shank 1, annular groove 6 is provided with positioned at outer end, and forms the circle in outside
Tabular bottom seat 7；Formed with a transition taper slope for being easy to positioning between described annular groove 6 and upper cylindrical handle of a knife 1
8；Graininess hard alloy layer 5 on the bit body 2 is covered with the conical outer wall face of whole cone, the cone
Bottom is also integrally formed with one narrow section of transition connecting cylinder body 9, and the described one of cylindrical knife shank 1 is mutually connected on the connecting cylinder body
Among 9 outboard end.
The utility model is to be evenly distributed with many cylindricality hard alloy in the front-end-cone angle head of bit body 2, and
Because the cylindricality hard alloy is deeply embedded in the corresponding deep hole in cone angle head simultaneously firm welding, the jail of welding is substantially increased
Solidity, the wearability of product is added, improve the service life of product；Other the utility model is also in the taper of bit body 2
Using double-deck broken alloy welding deposit technology formed with graininess hard alloy layer in outside wall surface, this also substantially increases the resistance to of product
Mill property, the same service life for improving product.
Claims (2)
1. a kind of mining pick, it is mainly integrally made up of cylindrical knife shank and cone bit body, it is characterised in that described
