Abstract
A kind of lithotrite toothing, it includes the block tooth body of a cuboid, it is work surface above the tooth body, the work surface is provided with the tooth head of wedge angle type positioned at leading section, described tooth head is by front-seat two and the big block hard alloy blocks that connect are constituted, each in the pointed shape end face for upwarping, the tooth head top area that the big block hard alloy blocks are constituted is higher by the work surface more than 1/3rd of whole face area above tooth head for the leading section of per block hard alloy blocks；It is fitting surface below the tooth body, wherein with inclined oblique fitting surface obliquely after being a middle arc transition in the fitting surface in centre position to rearward end；It has rational in infrastructure, and easy to install and use, overall tooth header structure fastness is good, wear-resisting, so as to increase the service life, the features such as improve work efficiency.
Description
Technical field
The utility model relates to a kind of lithotrite toothing, belongs to Ore mechanical equipment technical field.
Background technology
Mining industry lithotrite is a kind of common mining powder equipment, is generally used for the primary comminution of Ore.Existing mining industry is broken
The tooth head of stone machine by with drive it is pivotally connected after, collision type contact is carried out to Ore at work, so as to Ore is smashed；
But existing lithotrite tooth head is made using hard metal material, under the shock and vibration of Ore, tooth header structure is easily damaged
It is bad, it is even using Hardmetal materials etc. but not reasonable because of structure design in the working head of tooth head, easily cause tooth
Other positions of head are clashed into by Ore, so that whole tooth header structure is damaged, it is often necessary to even if changing tooth head, affect work
Efficiency, increases 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, using peace
Dress is convenient, and overall tooth header structure fastness is good, wear-resisting, from increasing the service life, improves the lithotrite toothing of work efficiency.
The purpose of this utility model is addressed by following technical proposals：A kind of lithotrite toothing, it includes
The block tooth body of one cuboid, is work surface above the tooth body, and the work surface is provided with wedge angle type positioned at leading section
Tooth head, described tooth head is by front-seat two and the big block hard alloy blocks that connect are constituted, per block hard alloy blocks
Each in the pointed shape end face for upwarping, the tooth head top area that the big block hard alloy blocks are constituted is more than whole for leading section
/ 3rd of face area, are higher by the work surface above tooth head；It is fitting surface below the tooth body, wherein
With inclined oblique fitting surface obliquely after being a middle arc transition in the fitting surface in centre position to rearward end.
As preferred：The tooth lower head front end face is front bevel that is downward and inside contracting, and in the rear end face of tooth body
For from the top down and the back bevel that extends out, and the inclined-plane of front bevel and back bevel in same incline direction.
This 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 as to increase the service life, improve work efficiency the features such as.
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.
Specific embodiment
This utility model is described in detail below in conjunction with accompanying drawing：Shown in Fig. 1-3, one kind described in the utility model
Lithotrite toothing, it includes the block tooth body 1 of a cuboid, is work surface 2 above the tooth body 1, the work surface 2
Leading section is provided with the tooth head 3 of wedge angle type, described tooth head 3 is by front-seat two and the big block hard alloy blocks 4 that connect
Constitute, the leading section of per block hard alloy blocks 4 is each in the pointed shape end face 5 for upwarping, the big block hard alloy blocks 5
The 3 top area of tooth head of composition is higher by the work more than 1/3rd of 2 area of whole work surface above tooth head 3
Face 2；It is fitting surface 6 below the tooth body 1, wherein the fitting surface in centre position to rearward end is 7 mistake of a middle circular arc
With inclined oblique fitting surface 8 obliquely after crossing.
Shown in figure, 3 lower front end face of the tooth head is front bevel 9 that is downward and inside contracting, and in the rear end of tooth body 1
Face is from the top down and the back bevel 10 that the extends out and inclined-plane of front bevel 9 and back bevel 10 in same incline direction.
This utility model is the big alloy block that two chips with side-by-side are arranged in tooth head, increased the hard alloy of work surface above
Area, so as to substantially increase the wearability and service life of product.
