Background

The hammer crusher is one of common crushing equipment for crushing medium and hard ores, the hammer head is one of core parts of the hammer crusher, the hammer head directly strikes materials when the crusher runs at a high speed and finally crushes the materials into proper material strength, and the stronger the impact capacity of the hammer head is, the better the effect of crushing the materials is; but the tup is at the in-process of constantly smashing, and the tup constantly wears, just need change new tup behind the tup surface wearing and tearing, and life is short, and the tup after wearing and tearing can not be utilized once more, and extravagant material increases the cost simultaneously.

Disclosure of Invention

The utility model discloses a solve among the prior art problem that the tup needs whole change, incremental cost, provide an easy operation, simple to operate and reduce cost's combination formula breaker tup.

In order to realize the purpose, the technical scheme of the utility model is that:

a combined crusher hammer comprises a hammer head, wherein the hammer head comprises an upper hammer head and a lower hammer head, the upper hammer head and the lower hammer head are in mortise and tenon joint, the upper part of the upper hammer head is of a cuboid structure, the lower part of the upper hammer head is of a frustum of prism structure, a groove is formed in the top of the upper hammer head, counter bores are formed in two opposite sides of the upper hammer head, and the counter bores are communicated with the groove; a bulge is fixed at the bottom of the upper hammer head, and a through hole is formed at the bottom of the bulge; the improved hammer is characterized in that a mortise is formed in the top of the lower hammer head and matched with the protrusion, mounting holes are formed in two opposite sides of the lower hammer head and communicated with the mortise.

Further, the groove is of a rectangular structure and is used for connecting the hammer handle.

Furthermore, the protrusion is of a T-shaped structure, the mortise is of a T-shaped structure, and the mortise and the protrusion are in clearance fit.

Furthermore, M-shaped grooves are formed in two sides of the upper hammer head, and a trapezoidal groove is formed in the bottom of the lower hammer head.

Further, the through hole has the same diameter as the mounting hole.

Through the technical scheme, the beneficial effects of the utility model are that:

the utility model has the advantages that the hammer head of the crusher is in a combined design, and only the lower hammer head is replaced without replacing the whole hammer head after the hammer head is worn; the replacement is convenient, and the problems of cost increase and resource waste caused by the integral replacement of the hammer head are prevented; the upper hammer head and the lower hammer head are in mortise-tenon joint, so that the connection stability is good, and the strength of the hammer head is increased; the upper hammer head is provided with a groove, so that the hammer handle can be conveniently inserted into the upper hammer head and is fixedly connected through a pin shaft, and the replacement is convenient; the M-shaped groove is formed in the upper hammer head, the trapezoidal groove is formed in the lower hammer head, the used materials are reduced, the requirement on kinetic energy is lowered, and meanwhile the manufacturing cost is lowered.

The reference numbers in the drawings are as follows: the hammer comprises a lower hammer head 1, an upper hammer head 2, a mounting hole 3, a through hole 4, a counter bore 5, a groove 6, a mortise 7, a bulge 8, an M-shaped groove 9 and a trapezoidal groove 10.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 5, a combined crusher hammer head includes an upper hammer head 2 and a lower hammer head 1, the upper hammer head 2 and the lower hammer head 1 are in mortise and tenon joint, the upper hammer head 2 and the lower hammer head 1 are both cast, the upper hammer head 2 is cast from low carbon alloy steel, the lower hammer head 1 is cast from wear-resistant materials, such as high chromium alloy materials, in this embodiment, the upper hammer head weighs 7kg, and the lower hammer head weighs 3 kg; the upper part of the upper hammer head 2 is of a cuboid structure, the lower part of the upper hammer head 2 is of a prismatic table structure, a groove 6 is formed in the top of the upper hammer head 2, and the groove 6 is of a rectangular structure; counter bores 5 are formed in two opposite sides of the upper hammer head 2, and the counter bores 5 are communicated with the grooves 6; a bulge 8 is fixed at the bottom of the upper hammer head 2, the bulge 8 is of a T-shaped structure, and a through hole 4 is formed in the bottom of the bulge 8; the top of the lower hammer head 1 is provided with a mortise 7, the mortise 7 is of a T-shaped structure, the mortise 7 is in clearance fit with the protrusion 8, two opposite sides of the lower hammer head 1 are provided with mounting holes 3, the mounting holes 3 are communicated with the mortise 7, and the mounting holes 3 are the same as the through holes 4 in aperture;

in order to optimize the product structure, save resources and improve the efficiency, the M-shaped groove 9 is arranged on two sides of the upper hammer head 2, the trapezoidal groove 10 is arranged at the bottom of the lower hammer head 1, the weight is reduced, the requirement on the kinetic energy is reduced, and the manufacturing cost is reduced.

When the hammer is used, the bulge 8 of the upper hammer head 2 is inserted into the mortise 7 of the lower hammer head 1; at the moment, the mounting hole 3 is communicated with the through hole 4, the mounting hole 3 is connected with the through hole 4 through a pin shaft, so that the upper hammer head 2 is fixedly connected with the lower hammer head 1, the top of the upper hammer head 2 is provided with a groove 6 for connecting with a hammer handle, the hammer handle is inserted into the groove 6, and the upper hammer head 2 is connected with the hammer handle by penetrating through the counter bore 5 and the hammer handle through a pin; when the lower hammer head 1 is seriously worn, the whole hammer head does not need to be replaced, and only the pin in the mounting hole 3 and the through hole 4 needs to be disassembled to replace the lower hammer head 1, so that the method is convenient and quick, and saves the cost; the breaker tup in this embodiment is used for brickyard breakage, in the use, only uses 1 both sides of lower part tup to be used for the breakage, consequently, trapezoidal groove 10 is seted up in 1 middle part of lower part tup for weight reduction reduces the requirement to kinetic energy, reduces manufacturing cost simultaneously.
