Abstract

An impact type plate breaking hammer device includes a rotor holder; a plate hammer is installed on the rotor holder by a wedge and a plate hammer supporting piece; grooves are arranged on two sides of the plate hammer; convex bars are arranged on the wedge; and grooves and convex bars are engaged. In the impact type plate breaking hammer device, a plurality of grooves arranged on two sides of the plate hammer are engaged with convex bars on the wedge; it is probably to increase height of the plate hammer by turning over the plate hammer when it is worn so as to compensate wearing of the plate hammer, enable utilization ratio of the plate hammer to achieve 65-70% and decrease use cost of the device.

Description

The counterattack broken flat hammer device

Technical field

The utility model relates to field of cracking machine, particularly a kind of counterattack broken flat hammer device that is applicable in the impact breaker.

Background technology

Because the broken kinetic energy of impact breaker is from the rotor that is provided with bar, building stones are because bar high speed impact on the rotor and the bump on counterpunch board and fragmentation is crushed to desired particle size up to building stones.Building stones enter through bar and counterpunch board broken repeatedly from charging aperture, when the ore grain size after the fragmentation during less than the slit between tup and the counterpunch board, discharge with regard to bottom in the slave, are the product building stones after the fragmentation.Bar is as the attrition component in the equipment, and directly determine use cost its service life, how to improve the bar utilization rate and has just become the key that reduces cost, and existing can not regulate the bar utilization rate and is lower than 45%, wastes bigger.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of counterattack broken flat hammer device, can improve the utilization rate and the abrasion resistance of bar.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of counterattack broken flat hammer device, comprise rotor rack, and bar is installed on the rotor rack by wedge and bar back-up block;

Flat hammer double sided interlocking is provided with a plurality of grooves, and the bar back-up block is provided with raised line, groove and raised line engagement fit.

Groove on the described bar simultaneously is three, and another side is two, and the position is staggered.

Described wedge locks by latch segment.

Bar on the described rotor rack has 4.

A kind of counterattack broken flat hammer device that the utility model provides, by being arranged on many flat hammer double sided grooves, being provided with raised line with wedge cooperates, when bar weares and teares, the bar turn-over can be promoted the height of bar, the wearing and tearing of compensation bar, can make the utilization rate of bar reach 65-70%, reduce the use cost of equipment.

The specific embodiment

In Fig. 1-Fig. 6, a kind of counterattack broken flat hammer device comprises rotor rack 5, and bar 1 is installed on the rotor rack 5 by wedge 2 and bar back-up block 4; 1 two-sided interlocking of bar is provided with a plurality of grooves 11, and bar back-up block 4 is provided with raised line 41, groove 11 and raised line 41 engagement fit.Groove 11 one sides on the described bar 1 are three, and another side is two, and the position is staggered.Described wedge 2 is by latch segment 3 lockings.Bar 1 on the described rotor rack 5 has 4.

After bar 1 wearing and tearing, with bar 1 turn-over, and make on the bar 1 compare with former mesh groove 11 by under groove 11 and bar back-up block 4 on raised line 41 on cooperate, thereby make bar 1 elevated height, compensate the wearing and tearing of bar.
