Description
Technical field
The utility model relates to a kind of lithotrite tooth head, belongs to mining machinery 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, so as to reduce use cost, improves the lithotrite tooth head of work efficiency.
The purpose of this utility model is addressed by following technical proposals：A kind of lithotrite tooth head, it includes one
Saddle tooth head body, the side upper end of the tooth head body are provided with the tooth head portion of wedge angle type, and tooth head lower head is arranged
There is socle raised vertically downward, on the tooth head body bottom surface on the inside of the socle, be provided with location hole, described tooth head portion uses
Hard alloy is embedded and constitutes in the concave lacking groove of tooth head body side upper end, before the tooth head body of the tooth head lower head
End face be provided with to contract in obliquely oblique before, and extend on socle leading flank；Tooth on the inside of the corner
Head body bottom surface is provided with two location holes being arranged side by side.
As preferred：The width in the tooth head portion is less than the width of tooth head body and is embedded in tooth head body side upper end
In the concave lacking groove in portion, tooth head body upper part central authorities are formed with sunk surface, and the opposite side afterbody of tooth head body upwarps to form a horse
Saddle；Described two location holes being arranged side by side are arranged on the annular lug of one evagination of tooth head body bottom surface, and in tooth head sheet
The bottom surface of body and socle medial surface constitute fitting surface.
As preferred：The tooth head portion is from the two lateral middle wedge angle heads for extending formation, the tooth head subordinate
Tooth head body width be more than top tooth head portion and be provided with the width of tooth head body at location hole；On a left side for tooth head body
It is respectively symmetrically on right two sides and is provided with two fixed installation holes.
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 reduce use cost, the features such as improve work efficiency.
