Abstract

Disclosed is a combined hammer head of a crusher, comprising a hammer body and a hammer head. The hammer head is fixed on the hammer body by bolts, and a check spring is padded between the bolts and the hammer head. The round shaft hole of the hammer body is inlaid with an abrasion-proof shaft sleeve after heat treatment. When A B square corners arranged at the front end of the hammer head are too worn to use, the hammer head can be dismounted, then be adjusted to turn back to be arranged again, and C D square corners of the hammer head can be used. The service life of the combined hammer head can be extended to more than one times without surfacing, and large quantities of raw materials can be saved, for the hammer head needs replacing without replacing the hammer body. With the utility model, the amount of heat treatment is decreased, and the cost is lowered.

Description

Combined hammerhead of crushing machine

The utility model is a kind of pulverizer combined type tup.

The hammer body and the tup of the employed tup of pulverizer of China are an integral body at present, hammer body one end has a circular axis hole, shortcoming is that the square toes when tup in use wear and tear and just can not use when in the arc-shaped again, that is to say two angles using square toes, service life is short, tup is damaged whole hammer body and is scrapped thereupon, wastes a large amount of raw material, cost height.

The purpose of this utility model has provided a kind of combined type tup, and it partly is made up of hammer body and H shape tup, with bolt with the tup partial fixing on hammer body, when tup part front end square toes two corner wears time spent more in the arc-shaped, tup partly can be unloaded, transposing is come, re-assembly, use two other corner, can use 4 corners, increase the service life, when tup has partly been damaged, only change the tup part, needn't change hammer body, save a large amount of raw material, reduce cost.

Pulverizer combined type tup as shown in drawings, form by hammer body 4 and tup part 3, the front end of hammer body 4 has boss, there is screw at the boss center, tup partly is a H shape, there is manhole the centre, so that bolt 1 passes, the groove of assembling fashionable dress H shape tup part 3 is enclosed within on the boss of hammer body 4, the manhole that passes the tup part with bolt 1 is fixed in the screw of hammer body 4 boss, between the groove of bolt 1 and tup part 3, be lined with retaining spring 2,, on the circular axis hole of hammer body 4, be inlaid with through heat treated anti-wear sleeve 5 to prevent bolt looseness.

After this combined type tup assembles by said structure, use tup part 3 front-end A B two corners earlier, when two in the arc-shaped can not re-using of corner wearing and tearing of AB, unclamp bolt 1, unload lower ram part 3, turn the CD square toes, load onto again, re-use two corners of CD, can increase the service life more than one times without built-up welding.

This combined type tup and its advantage of existing monoblock type tup comparison are:

1, reduces the heat treatment amount, only need tup part and axle sleeve are heat-treated;

2, increase the service life, the monoblock type tup can only use two corners of tup, and the combined type tup can use 4 corners of tup part;

3, save a large amount of raw material, reduce cost, tup has partly been damaged, and only changes the tup part, needn't change hammer body.

Accompanying drawing is a pulverizer combined type hammehead structure schematic diagram.

Mark among the figure: 1, bolt; 2, retaining spring; 3, tup part; 4, hammer body; 5, anti-wear sleeve.

Claims

Pulverizer combined type tup is made up of hammer body 4 and tup part 3, the front end that it is characterized in that its hammer body 4 has boss, screw is arranged in the middle of the boss, tup part 3 is a H shape, just the manhole that passes with bolt is arranged in the middle of its groove, with bolt 1 tup part 3 is fixed on the hammer body 4, between the groove of bolt 1 and tup part 3, is lined with retaining spring 2, on the circular axis hole of hammer body 4, be inlaid with through the heat treated anti-axle sleeve 5 that wastes.
