Description

Impact breaker

The utility model relates to a kind of impact breaker.

Current, the impact breaker of use (claiming impact crusher again) causes some parts of complete machine easy to wear owing to exist structural unreasonablely, has influenced complete machine service life, reduces work efficiency, has improved cost.

The purpose of this utility model is exactly that a kind of improved impact breaker is provided in order to overcome the deficiencies in the prior art.

The purpose of this utility model can reach by following measure:

This disintegrating machine comprises motor, rotor disk, upper machine body, lower body, limit backplate, counterattack plate body, counterpunch board, bar, charging aperture, and concrete structure is:

A, fixedly supporting plate (12) and rotor disk (7) are fixed together, and fixedly supporting plate is provided with V-type groove (19), and groove is provided with limited block (20).Bar (2) two sides is respectively arranged with V-type boss (13), wherein being installed in fixedly, the one side V-type boss of V-type groove (19) lining of supporting plate is provided with the groove (21) that matches with limited block (20), another side V-type platform is installed in V-type groove (18) lining of compacted iron (11), the compacted iron another side is provided with Qian type groove (17), and compacted iron is installed on the rotor disk by Qian type groove.Pressing plate (10) is fixed on compacted iron on the rotor disk.

B, counterpunch board (5) are provided with boss (15), have band square hole (16) slightly on the boss, and counterpunch board is fixed on the liner plate of counterattack plate body (4) and limit backplate (3) by the iron slightly (14) that is fixed in the square hole.

The purpose of this utility model can also reach by following measure:

Fixedly V-type groove on the supporting plate and the V-type groove on the compacted iron, and even 90 ° of the angle α of the V-type boss on the bar.

Beater plate (8) is installed in lower body (9).

Boss quantity on the counterpunch board is 1-3.

The utlity model has following advantage:

1, structure is more reasonable.

2, improve the service life of consumable accessory.

3, increase work efficiency.

Below the utility model is described further:

Present technique mainly is the improvement to existing product part parts and mounting structure, is in particular in three aspects:

1, original structure be bar by being bolted on the rotor disk, nuts is made a mess of by stone easily at work, and bar is come off, influence is produced.Present structure is to have increased compacted iron and pressing plate, bar is installed in the V-type groove of fixedly supporting plate and compacted iron by two sides V-type boss, two upper limit position blocks of burn-oning on the V-type groove of fixing supporting plate, limited block just in time are stuck in the groove on the bar boss, and bar can not laterally be gone here and there; The both sides of compacted iron adopt pressing plate that it is fixed on the rotor disk, so just bar have been fixed on the rotor disk, make bar overcome former shortcoming.

2, counterpunch board also is by being bolted on limit backplate and the counterattack body nuts breakage easily in the work, influence production in original structure.Structure after the improvement is to have increased by two short wooden stakes at the back side of counterpunch board, and band square hole is slightly arranged on the short wooden stake, and counterpunch board passes through ferropexy slightly on limit backplate and counterattack plate body, the shortcoming before so just having overcome.

3, in the former structure, lower body does not have beater plate, and has increased beater plate in new construction, makes through broken stone can remove corner angle through behind the beater plate, and is slick and sly more, improved the quality of stone.
