The utility model aims to provide a breaking hammer applied to a crusher, which is convenient for replacing a worn hammer head, effectively reduces the downtime of equipment and reduces the use cost of the crusher.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a be applied to quartering hammer of breaker, includes tup and hammer handle, the hammer handle includes a siphonozooid, and the connector of the intermediate part outside extension of siphonozooid, the one end that the siphonozooid was kept away from to the connector is equipped with the recess, is equipped with the through-hole of stepping down on the connector of recess one side, is equipped with first installation through-hole on the connector of recess opposite side, tup one end is equipped with second installation through-hole, and the tup is equipped with the one end of second installation through-hole and inserts in the recess, the bolt passes the through-hole of stepping down, second installation through-hole, first installation through-hole then connect with lock nut soon the tup with the connector locking is in the same place, and bolt head part is in the through-hole of stepping down.

The improved structure is characterized in that the yielding through holes are formed in the first mounting through hole and the second mounting through hole respectively.

In a further improvement, the connecting body is generally T-shaped, and one end of the connecting body, which is connected with the tubular body, is generally perpendicular to the tubular body.

Still further, the connector is equipped with recess one end both sides and all is equipped with first arc breach. First arc breach forms the structure of stepping down on the one hand, and on the other hand is convenient for the dismantlement of tup, installation change, can also reduce the occupation of position.

The improved hammer is a plate-shaped body, and both sides of one end of the hammer, which is provided with a second mounting through hole, are provided with second arc-shaped notches. When the width of tup is greater than the width of connector, design second arc breach makes tup one end conveniently insert in the recess of connector to obtain better location.

In a further improvement, two locking nuts are screwed with the bolt, and the two locking nuts are close to each other. Therefore, the hammer head and the hammer handle are not easy to loosen.

In a further improvement, the cross section of the abdicating through hole is hexagonal, and the cross section of the bolt head is hexagonal. Therefore, the bolt can be well prevented from rotating through the matching of the bolt head and the abdicating through hole, and the locking nut can be conveniently screwed and installed.

Preferably, the tubular body is a circular tube body. The tubular body is convenient to be installed in a matching way with a connecting shaft on the crusher.

The breaking hammer is designed into a hammer head and a hammer handle, the hammer handle comprises a tubular body, the middle part of the tubular body extends outwards to form a connecting body, one end of the connecting body, far away from the tubular body, is provided with a groove, the connecting body on one side of the groove is provided with a abdicating through hole, the connecting body on the other side of the groove is provided with a first mounting through hole, one end of the hammer head is provided with a second mounting through hole, one end of the hammer head, provided with the second mounting through hole, is inserted into the groove, and the hammer head and the connecting body can be locked together by penetrating through the abdicating through hole, the second mounting through hole and the first mounting through hole through bolts and then being screwed with a locking nut. When the hammer head is abraded, the hammer head can be conveniently replaced by detaching the bolt, the connection part of the hammer handle and the crusher does not need to be detached, and the speed of disassembling, assembling and replacing the hammer head is high. The shutdown time of the equipment can be effectively reduced, and the use cost of the crusher is reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, a breaking hammer applied to a crusher comprises a hammer head 1 and a hammer handle 2, wherein the hammer handle 2 comprises a tubular body 21, the tubular body 21 is in a circular tube shape, a connecting body 22 extends outwards from the middle part of the tubular body 21, the connecting body 22 is substantially in a T shape, one end 220 of the connecting body 22 connected with the tubular body 21 is substantially perpendicular to the tubular body 21, and one end of the connecting body 22 far away from the tubular body 21 is provided with a groove 221. The connecting body 22 on one side of the groove 221 is provided with two abdicating through holes 222 with hexagonal cross sections, the connecting body 22 on the other side of the groove 221 is provided with two first mounting through holes 223, and the two sides of one end of the connecting body 22 provided with the groove 221 are both provided with first arc-shaped notches 224.

As further shown in fig. 5, the hammer head 1 is a plate-shaped body, two second mounting through holes 11 are formed in one end of the hammer head 1, and second arc-shaped notches 12 are formed in two sides of one end, provided with the second mounting through holes 11, of the hammer head 1.

One end of the hammer head 1 provided with the second mounting through hole 11 is inserted into the groove 221, the two bolts 3 respectively penetrate through the abdicating through hole 222, the second mounting through hole 11 and the first mounting through hole 223 and then are screwed with the two locking nuts 4 to lock the hammer head 1 and the connecting body 22 together, the cross section of the head of each bolt 3 is hexagonal, part of the cross section of the head of each bolt is positioned in the abdicating through hole 222, the number of the locking nuts 4 screwed with one bolt 3 is two, and the two locking nuts 4 are abutted together.
