Abstract
The invention provides a durable hammer of a crusher, which comprises a hammer handle (1) and hammers (2) connected with the hammer handle. A columnar hammer (2) with a cavity (3) is respectively symmetrically arranged on the two sides of the upper end head of the hammer handle; a shaft pin (4) with a cap passes through central holes of the two columnar hammers (2) and a pin hole at the end heads of the hammer handle (1); the two columnar hammers are connected with the end head of the hammer handle; and the pin shaft (4) is fixed by using a clamp spring (5). The shaft pin (4) is in clearance fit with the central holes of the columnar hammers and the pin holes at the end heads of the hammer handle so that the hammer can be automatically aligned with the part with relatively small abrasion, namely uniform abrasion of the hammer can be realized and the service life of the hammer is improved. When the hammer is replaced, the pin shaft is pulled out only and then the hammer can be conveniently replaced without disassembling the hammer handle from a rotor pin shaft, maintenance time can be reduced, and operation difficulty is decreased.
Description
Technical field
The present invention relates to a kind of tup that is used for disintegrating machine.
Background technology
Disintegrating machine is widely used in the fragmentation of mine, building materials material, in shattering process, the tup of disintegrating machine be directly with the parts of the object that is broken (as ore etc.) bump, extruding, friction, when tup is met the one side serious wear of broken thing head-on, promptly can not re-use, will change one time tup in common one day.Existing disintegrating machine mostly is to adopt monoblock cast or forging, also has part to adopt the countersunk head screw rod, adds outer repair welding face high-abrasive material and connects with hammer handle, and complexity is installed, and maintenance man-hours is many, the material consumption height.No matter the grinder hammerhead of which kind of form as long as tup may wear to a certain degree, just can not be used again, stock utilization is low.Therefore the quality of tup quality, material, shape, connecting mode is directly connected to output, quality, cost and the production efficiency of product.
Summary of the invention
In order to solve existing grinder hammerhead unreasonable structure, problem that utilization rate is low, a kind of durable hammer that is used for disintegrating machine that provides, it can make tup adjust automatically to impact angle uses continuously, improves service life, and make change easy to connect reliable.
The technical solution used in the present invention is:
A kind of durable hammer of crusher, comprise hammer handle and the tup that links to each other, it is characterized in that: both sides, hammer handle one termination are symmetrical arranged a column tup that has cavity respectively, the pin-and-hole that one pivot pin passes each column tup centre bore and hammer handle termination is set, two column tups are connected in the hammer handle termination.
The invention has the beneficial effects as follows, in impacting process, after the part wearing and tearing of tup, cause and lay particular stress on, because the pin-and-hole of pivot pin and column tup centre bore and hammer handle termination is matched in clearance, tup can automatic capturing, the less one side of wearing and tearing is impacted, promptly can reach the tup uniform wear, improve the service life of tup.As long as pull out bearing pin during owing to the replacing tup, promptly conveniently replaced tup, hammer handle need not be pulled down from the rotor bearing pin, can reduce maintenance time, reduces operation easier.
Description of drawings
Further specify this use is novel below in conjunction with drawings and Examples.
Fig. 1 is a durable hammer of crusher structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of durable hammer of crusher provided by the invention comprises hammer handle 1 and the tup 2 that links to each other, and hammer handle and tup form the rotation stroke around the gyroaxis hole of the lower end of hammer handle 2.
Upper end both sides at hammer handle 2, be symmetrical arranged a column tup 2 that has cavity 3 respectively, other is provided with the pivot pin 4 of a band cap, the pin-and-hole of the centre bore of two column tups 2 and hammer handle 1 termination about it passes, two column tups are connected in the hammer handle termination, and wherein the cavity of left side column tup 2 partly adopts jump ring 5 that bearing pin 4 is fixing.Pivot pin 4 is matched in clearance with the pin-and-hole of column tup centre bore and hammer handle termination, makes the tup can the less part of automatic capturing wearing and tearing.
Claims (2)
1. durable hammer of crusher, comprise hammer handle (1) and the tup that links to each other, it is characterized in that: hammer handle (1) one end both sides are symmetrical arranged a column tup (2) that has cavity (3) respectively, pass the centre bore of each column tup and the pin-and-hole of hammer handle one end by pivot pin (4), two column tups (2) are connected in hammer handle one end both sides.
2. durable hammer of crusher according to claim 1 is characterized in that: pivot pin (4) is matched in clearance with the pin-and-hole of column tup (2) centre bore and hammer handle (1) one end.
