Abstract

The utility model relates to an impact crusher rotator, which comprises a rotator body (1) with a groove (3) and a protective block (2) arranged on the outer side of the rotator body (1), wherein a flat hammer (4) is seized on the groove (3). The impact crusher rotator is characterized in that two ends of the flat hammer (4) are fixedly connected with flat hammer baffles (5) along the radial direction of the rotator body (1). The flat hammer on the rotator is pushed in the groove of the rotator body from the lateral side, and two sides of the flat hammer are baffled by the flat hammer baffles, which is convenient and fast in replacement. Because the protective block can cover the rotator body with a large covering area, the rotator body can be better protected, the structure is simple and the production cost is reduced.

Description

The impact breaker rotor

Technical field

The utility model relates to a kind of parts of disintegrating machine, is a kind of impact breaker rotor specifically.

Background technology

Disintegrating machine is widely used in various ores, cement, refractory material, bauxite grog, diamond dust, frit, mechanism building sand, building stones and various metallurgical slag, and impact breaker is a kind of in numerous disintegrating machines.Material at fragmentation carries out fragmentation and screening; its fragmentation all be a little hard objects; and this hard objects is carried out fragmentation is by rotor material to be impacted particle; therefore the good job of rotor is exactly the efficient of whole disintegrating machine particle; rotor is one of most important parts of whole disintegrating machine; therefore need just need protect the rotor on the disintegrating machine, and the replacing of rotor has also just become a very important program, whether the convenience of replacing directly has influence on crushing efficiency.

Someone has designed the impact breaker rotor according to these characteristics, and it is made up of rotor subject, protective block, skewback group and bar, but this epitrochanterian protective block covering rotor area is smaller, complex structure, cost height; And fixedly bar is to use the skewback group, and the skewback group quantity that not only is used for fixing is many, and skewback group complex structure, the processing cost height, when needs were changed bar, the skewback group need be at the bolt of twisting on it, take out the skewback group after, just can take out bar, it is very time-consuming to change bar, and efficient is low.

As mentioned above, there is following deficiency in prior art: it is smaller that protective block covers rotor area, complex structure, cost height; Skewback group quantity is many, and skewback group complex structure, the processing cost height; It is very time-consuming to change bar, and efficient is low.

Summary of the invention

The utility model has solved protective block that prior art exists, and to cover rotor area smaller, complex structure, and the problem that cost is high provides a kind of simple in structure and impact breaker rotor that area coverage is big.

The skewback group quantity that the utility model has also solved the prior art existence is many, and skewback group complex structure, and the problem that processing cost is high provides a kind of impact breaker rotor that uses the bar baffle plate to replace the skewback group.

It is very time-consuming that the utility model has also solved the replacing bar that prior art exists, and inefficient problem provides a kind of replacing bar impact breaker rotor easily.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of impact breaker rotor, comprise the rotor subject that has groove and be located at the protective block in the rotor subject outside, on this groove, be connected with bar, it is characterized in that described bar is connected with the bar baffle plate along the radially two ends of rotor subject.Add fixedly bar of bar baffle plate in the bar outside, make dismounting all become very convenient, during use, advance bar in the groove of rotor subject from side, both sides refill the bar baffle plate and prevent that bar from from wherein one bringing out, when changing bar, only need take out the bar baffle plate then, directly take out bar then in the groove and get final product, the replacing bar is very convenient, quick.

As preferably, described protective block comprises big protective block and little protective block, the fastening bar of this little protective block one end, and an other end amplexiforms big protective block.Effect becomes two parts with protective block, and is not only simple in structure, and strengthened the area of protective block, can the better protection rotor subject.

As preferably, described bar becomes the little oblique I shape in big centre, two ends, and both sides, position little in the middle of it are respectively in abutting connection with bar baffle plate and little protective block, and the groove shapes on this oblique I shape and the rotor subject is mated.This epitrochanterian groove is young interior big shape; bar advances in the groove of rotor subject from side; utilize the little protective block in both sides to fixedly connected then with the bar baffle plate; be not easy to unclamp; and little protective block is close to the outer surface of rotor subject; play the rigid percussion that the protection rotor subject is subjected to particle as far as possible less, improve service life.

As preferably, the outer circular arc body that surrounds of described rotor subject.Make easy to processly, particle efficient is higher.

The utility model is skillfully constructed, and makes it have following beneficial effect compared with the prior art:

1, use fixedly bar of bar baffle plate, very convenient during replacing, quick;

2, protective block is simple in structure, and the area of covering rotor subject is big, can better protect rotor subject, prolongs its service life;

3, use the bar baffle plate, simple in structure, processing cost is low.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model:

Fig. 2 is the broken section structural representation of Fig. 1.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.

Embodiment 1.See Fig. 1 and Fig. 2, this routine a kind of impact breaker rotor, comprise the rotor subject 1 that has groove 3, the outer circular arc body that surrounds of this rotor subject 1, and be located at the protective block 2 in rotor subject 1 outside, and on this groove 3, being connected with bar 4, described bar 4 is connected with bar baffle plate 5 along the radially two ends of rotor subject 1, this bar baffle plate 5 is screwed the both sides of bar 4, prevents that it from moving outward.

Wherein, described protective block 2 comprises big protective block 21 and little protective block 22, and big protective block 21 width are wideer than the width of little protective block 22, but thinner than little protective block 22; The fastening bar 4 of these little protective block 22 1 ends, an other end amplexiforms big protective block 21.The little oblique I shape in big centre, 4 one-tenth two ends of described bar, both sides, position little in the middle of it are respectively in abutting connection with bar baffle plate 5 and little protective block 21, and groove 3 form fit on this oblique I shape and the rotor subject, an and end of this bar 4 is higher than the periphery of rotor subject 1 are used for particle.
