Abstract
A combined pi hammer for an efficient powerful hammer type crusher is formed by a plate hammer and a hammer handle, and the hammer handle is of a pi type structure formed by a double-lug form. The plate hammer and the hammer handle are matched with each other through convex and concave wedge-shaped grooves, the axis of the grooves and the central hole for connecting the hammer handle form a certain included angle in the horizontal direction, and the centrifugal force of the hammer during rotation is effectively resisted. The combined hammer of the pi structure is divided into the plate hammer and the hammer handle, and the utilization rate of the plate hammer which is largely abraded due to direct collision with materials in the crushing process is increased to the largest extent by reducing the occupied volume of the non-abrasion portion in the plate hammer. Due to the fact that compared with a hammer handle of a traditional hammer, the width of two sides of the combined hammer of the pi type structure, the crushing area of the combined hammer can achieve complete covering, an easily-damaged part is effectively protected, and service life of the crusher is prolonged.
Description
Technical field
The utility model relates to a kind of combination π hammer of effective powerful hammer mill, is applicable to system sand horizontal crusher.
Background technology
Existing broken sector application horizontal crusher all adopts monaural hammer handle combining structure, and it has number of drawbacks in shattering process: 1, sweep away the face deficiency, broken ratio is low; 2, the rotor disc is easy to wear, and it is high to change the spare part expense; 3, power consumption is big, and energy consumption increases.
Summary of the invention
The utility model purpose is to provide a kind of combination π hammer of effective powerful hammer mill, and this combination π hammer has effectively contended with and hammered the centrifugal force in rotary course into shape, has improved the utilization rate of hammer.And can a positioning sleeve be installed between two handle tails of hammer handle when using, can effectively prevent mandrel axial float when rotated.
Concrete scheme is following:
A kind of combination π hammer of effective powerful hammer mill; It is by hammer handle, bar, conical head bolt and add high nut and constitute; Be arranged to a recessed trapezoidal wedge-like in the installation place of hammer handle; A protruding trapezoidal wedge-like is arranged in the installation place of bar, and hammer handle and bar agree with through mutual concavo-convex trapezoidal wedge groove each other, and with conical head bolt with to add high nut fastening; What hammer handle adopted is the π shape structure that the ears form forms a uniqueness.The center line of its groove forms certain inclination angle with the centre bore horizontal direction that hammer handle links, and hammer centrifugal force when rotated effectively contends with; Adopt the combination hammer of π type structure bigger increase to be arranged because of its traditional hammer hammer handle both sides width; Cover in the time of can making it broken comprehensively; Can play a protective role to disc during operation; And can a positioning sleeve be installed between two ears of hammer handle when using, can effectively prevent mandrel axial displacement when rotated.

,Hammer handle; 2, bar; 3, conical head bolt; 4, add high nut.
The specific embodiment
Below in conjunction with accompanying drawing,, scheme is specified as an embodiment.
With reference to figure, be arranged to a recessed trapezoidal wedge-like in the installation place of hammer handle, a protruding trapezoidal wedge-like is arranged in the installation place of bar, and hammer handle and bar agree with through mutual concavo-convex trapezoidal wedge groove each other, and with conical head bolt with to add high nut fastening; What hammer handle adopted is the π shape structure that the ears form forms a uniqueness, and during use, hammer handle two ear center lines connect through mandrel.
Claims (1)
