Traditional hammer dish is all circular, is generally circumferentially evenly provided with 4 axis holes, and therefore can insert 4 hammer axles, owing to being circumferentially be uniformly distributed, therefore center of gravity is positioned at the center of circle of hammer dish, can not offset.And hammer tup sheathed on axle into shape in long knockout process and can wear and tear, thus tup shortens, make spacing between tup and lower screening deck become large, some large-sized materials can drop on the sieve plate of below, not only can stop on sieve plate, fragmentation cannot be proceeded, even can block sieve aperture, at this moment just need the tup more renewed, so just increase production cost, and the tup changed cannot continue to use, and can only give up.
Summary of the invention
The invention is intended to provide a kind of hammer of hammer crusher dish, after solving the wearing and tearing of present tup, the tup that must more renew, and old tup changes the problem that just cannot continue to use.
A kind of hammer of hammer crusher dish in this programme, comprise hammer dish body, described hammer dish body is circular, the circle centre position of described hammer dish body is provided with the circular hole passed for main shaft, described circular hole periphery is evenly provided with some axis holes, described axis hole is divided into two groups, be respectively internal layer axis hole and outer axis hole, described internal layer axis hole and outer axis hole are four and are uniformly distributed around circular hole, the spacing of described outer axis hole and circular hole is greater than the spacing of internal layer axis hole and circular hole, described internal layer axis hole and outer axis hole spaced apart, the card of described hammer dish body is provided with the circular baffle plate for distinguishing internal layer axis hole and outer axis hole.
Operation principle of the present invention and beneficial effect:
Main shaft is through circular hole, hammer dish body can be driven to rotate, first internal layer axis hole four axis holes in insert hammer axle, then new tup is arranged on hammer axle, when after use a period of time, tup is worn and shortens, the distance of tup and liner plate becomes large, at this moment will hammer axle into shape to extract out, insert outer axis hole four axis holes in, again corresponding tup is loaded onto, spacing due to outer axis hole and circular hole is greater than the spacing of internal layer axis hole and circular hole, therefore the Distance Shortened of tup and liner plate, make tup can continue to use, adopt the hammer dish body of this programme, tup after being worn need not more renew immediately, but change position continuation use, improve the service efficiency of tup, reduce the input cost of enterprise, in order to prevent when changing axis hole, there is entanglement in the position that the wrong plug of hammer axle enters axis hole, side is provided with for distinguishing internal layer and outer field circular baffle plate, can the axis hole of differentiation ectonexine clearly, make operator can not will hammer axle wrong plug into shape.
Further, internal layer axis hole and outer axis hole are 7cm in the distance of hammer dish body radial direction, because tup has the dimensions, so internal layer and outer field axis hole need certain required distance, if distance is greater than 7cm, the axis hole of internal layer is too near to the center of circle of hammer dish body, between tup, rotation can collide, exacerbate the wearing and tearing of tup, if and distance is less than 7cm, the distance that hammer axle increases from internal layer to skin is too small, the utilization rate of tup cannot be reached maximum, when internal layer axis hole and outer axis hole are the best when the distance of hammer dish body radial direction is axis hole radius.
Further, axis hole radius is 3.5cm, and when axis hole radius is greater than 3.5cm, the distance of adjacent tup shortens, and can collide in high-speed rotation process, and tup is worn and torn, and when axis hole radius is less than 3.5cm, the diameter of hammer axle diminishes, and intensity reduces, and easily ruptures.
Further, the distance of outer field axis hole and periphery is 5cm, because tup is with in the collision process of material, violent shake can occur, hammer axle is driven to clash into axis hole inner headed face thus, if the distance of outer field axis hole and periphery is less than 5cm, the insufficient strength of hammer dish body can be caused, in the shock of hammer axle, rupture, if be greater than 5cm, then axis hole can be made overall close toward the hammer dish body center of circle, cause the hypotelorism between tup that collision mutually occurs.
Further, the edge of hammer dish body is round-corner transition, because hammer dish body inevitably will be subject to the friction of ore, so hammer dish body will require that it has certain wearability, and fillet can reduce the frictional force of side and periphery junction, improve the service life of hammer dish body.
