Abstract
The utility model discloses a kind of ring hammer of ring-hammer type crusher, and it includes hammer body and wear-resistant block, and the hammer body is provided with a round open-work in annular shape in diametric(al), and the hammer body cross section is circle；The trapezoidal shape of wear-resistant block, center line upper end are provided with cannelure, and lower end is provided with the dovetail groove tangent with hammer body outline, and centre is provided with justifies the equal-sized round open-work of open-work with hammer body；The wear-resistant block is fastened on hammer body outline, and circle open-work is relative on the wear-resistant block circle open-work and hammer body, and is fixed by bolt, split pin, channel nut, forms assembled ring hammer structure.Due to the wear-resistant block of high-wearing feature is installed on hammer body, wear-resistant block and material impacting, can be changed after abrasion during work；In addition, hammer body does not have to dismantle from bearing pin, maintenance time is saved, reduces maintenance cost.
Description
Technical field
It the utility model is related to a kind of ring hammer of ring-hammer type crusher.
Background technology
Ring hammer crusher be it is a kind of with ring hammer impact rotor formula disintegrating machine, material enter disintegrating machine after, first by
Acted on to the ring hammering blow rotated at a high speed with rotor and broken, pulverized material obtains kinetic energy at ring hammer simultaneously, at high speed
Ground rushes at crushing shell, is crushed for the second time, then falls on sieve plate, is sheared, extrudes, grinds by ring hammer, and material
Mutual collision between material further crushes, and is discharged through sieve aperture.Ring hammer is mostly annular shape, also known as top fuller at present.
Its outer ring surface is linear contact lay when it hits material, because contact area is small, crushing effect is bad, and ring hammer holds as the scope of attack
It is easy to wear；Prior art top fuller material typically selects potassium steel, although wearability is preferable, plasticity is poor, is easily broken off.
The content of the invention
The utility model is pacified on hammer body in view of the deficienciess of the prior art, provide a kind of ring hammer of ring-hammer type crusher
Fill wear-resistant block.
Technical scheme is used by the utility model solves its technical problem：A kind of ring hammer of ring-hammer type crusher, including
Hammer body and wear-resistant block, the hammer body are provided with a round open-work in annular shape in diametric(al), and the hammer body cross section is circle
Shape；The trapezoidal shape of wear-resistant block, center line upper end are provided with cannelure, and lower end is provided with the dovetail groove tangent with hammer body outline,
Centre is provided with justifies the equal-sized round open-work of open-work with hammer body；The wear-resistant block is fastened on hammer body outline, the wear-resistant block
Circle open-work is relative on circle open-work and hammer body, and is fixed by bolt, split pin, channel nut, forms assembled ring hammer structure.
Further, the thickness of the wear-resistant block is equal with hammer body cross-sectional diameter.
The beneficial effects of the utility model are, wear-resisting during work due to the wear-resistant block of high-wearing feature is installed on hammer body
Block and material impacting, it can be changed after abrasion；In addition, hammer body do not have to dismantled from bearing pin, save maintenance time, reduce maintenance into
This.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure top view.
Embodiment
As depicted in figs. 1 and 2, a kind of ring hammer of ring-hammer type crusher, including hammer body 5 and wear-resistant block 4, the hammer body 5 is in circle
Ring-type, and a round open-work is provided with diametric(al), the cross section of hammer body 5 is circle；The 4 trapezoidal shape of wear-resistant block,
Center line upper end is provided with cannelure, and lower end is provided with the dovetail groove tangent with the outline of hammer body 5, and centre is provided with justifies open-work with hammer body 5
Equal-sized round open-work；The wear-resistant block 4 is fastened on the outline of hammer body 5, and the wear-resistant block 4 justifies circle on open-work and hammer body 5
Open-work is relative, and is fixed by bolt 1, split pin 2, channel nut 3, forms assembled ring hammer structure.This structure can effectively prevent
Pine.The thickness of the wear-resistant block 4 is equal with the cross-sectional diameter of hammer body 5.
Hammer body 5 is by intensity is high, moulding good medium carbon steel makes, and wear-resistant block 4 is by the high Chrome iron castings of high rigidity, Gao Gezhu
Iron is the 3rd generation high-abrasive material after potassium steel and the hard IV cast irons of nickel, and its hardness can reach 60HRC, easy shape during it is organized
The M7C3 type carbide higher into microhardness, the quantity of the type carbide is bigger, and its wearability is better.Hammer body 5 is mainly held
The effect for the moment of flexure that is hit, wear-resistant block 4 and material impacting, broken task is completed, wear-resistant block 4 is replaceable after wearing, so abundant
The advantage of two kinds of materials has been played, has extended service life.
Claims (2)
1. a kind of ring hammer of ring-hammer type crusher, including hammer body and wear-resistant block, it is characterised in that：The hammer body is in annular shape, and
A round open-work is provided with diametric(al), the hammer body cross section is circle；The trapezoidal shape of wear-resistant block, center line upper end is opened
There is cannelure, lower end is provided with the dovetail groove tangent with hammer body outline, and centre is provided with saturating with the hammer body circle equal-sized circle of open-work
Hole；The wear-resistant block is fastened on hammer body outline, and circle open-work is relative on wear-resistant block circle open-work and hammer body, and by bolt,
Split pin, channel nut are fixed, and form assembled ring hammer structure.
A kind of 2. ring hammer of ring-hammer type crusher according to claim 1, it is characterised in that：The thickness and hammer of the wear-resistant block
Body cross-sectional diameter is equal.
