Abstract
The utility model discloses a pendulum hammer for a hammer crusher. Outward protruding raised parts are arranged at positions at which two impact surfaces of a hammer head are positioned. According to the utility model, the outward protruding raised parts are additionally arranged at two side impact surfaces of the pendulum hammer, so that the wear allowance of the hammer head is increased, the service life of the pendulum hammer is effectively prolonged, the replacement and halt time and the loss of spare parts of the pendulum hammer are reduced, the structure is simple and the needed investment is small.
Description
Technical field
The utility model relates to a kind of nothing that is used for broken bulk materials and stops up hammer mill, specifically a kind of pendulum that is used for hammer mill.
Background technology
Hammer mill such as PCXK type disintegrating machine are mainly used in broken lump coal and gangue, utilize the percussion of rotor high-speed rotation pendulum material to be implemented broken.The main cause that influences crushing and crushing effect is exactly the shape of pendulum, weight, guarantee the stable of above-mentioned parameter, and the control of the rate of wear is crucial.Mostly existing pendulum material is potassium steel, and shape is as shown in Figure 1, and tup 1 is rectangular; When shock surface 2 is when dotted portion is milled to fillet 21 among Fig. 1, it is big that the gap between tup 1 and the liner plate becomes, and crushing effect obviously descends; The essential pendulum of changing, the general average cycle of operation of pendulum is 210 hours.Change downtime and waste and old spare part and all become the biggest obstacle that disintegrating machine economy is used.
Summary of the invention
The purpose of the utility model is to the weak point that exists in the prior art, and a kind of pendulum that is used for hammer mill is provided, and can effectively prolong pendulum service life, minimizing replacing downtime and the loss of pendulum spare part.
For realizing above-mentioned purpose, the utility model has adopted following technical scheme: the position, two shock surface places of tup is respectively equipped with the protuberance to outer lug.
Because the tup of pendulum part makes width broadening through increasing protuberance, has increased the wear allowance of tup, can effectively prolong pendulum service life, reduce and change downtime and lose with the pendulum spare part.
Be to reduce of the influence of device structure remodeling, have groove in the middle of the tup end, weight that can the protuberance increase of balance both sides machine utilization and load strength of parts.
When broken toughness material,, radian is prone to after appearring in the tup wearing and tearing with the radian buildup, can cause long-pending stifled the narrowing down of blanking runner.For preventing buildup, a preferred version of the utility model is that protuberance to tup tail end is with the circular arc transition.
Can know that by technique scheme the utility model increases protuberance through the both sides shock surface of pendulum, thereby increase the wear allowance of tup; Effectively prolonged pendulum service life; Reduce and change downtime and the loss of pendulum spare part, and simple in structure, required investment is little.
Description of drawings
Fig. 1 is existing pendulum structural representation.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is another example structure sketch map of the utility model.
The specific embodiment
As shown in Figure 2, the position, two shock surface places of the utility model tup 1 is respectively equipped with the protuberance 3 to outer lug, to increase the wear allowance of tup 1, has groove 4 in the middle of tup 1 front end, with the weight of balance both sides protuberance 3 increases.
As shown in Figure 3, protuberance 3 to tup 1 tail end goes for broken toughness material with circular arc 31 transition, prevents with the radian buildup.
Claims (3)
1. be used for the pendulum of hammer mill, it is characterized in that: the position, two shock surface places of tup (1) is respectively equipped with the protuberance (3) to outer lug.
2. the pendulum that is used for hammer mill according to claim 1 is characterized in that: have groove (4) in the middle of tup (1) front end.
3. the pendulum that is used for hammer mill according to claim 1 and 2 is characterized in that: said protuberance (3) to tup (1) tail end is with circular arc (31) transition.
