Description

The rotor arrangement of impact breaker

Technical field

The utility model relates to a kind of rotor arrangement of impact breaker, mainly is applicable to impact breaker.

Background technology

Impact breaker can handle many materials, and it is fairly simple on version because production efficiency is higher, and conveniently moving is widely used in industries such as building materials, traffic, the energy, cement, mine, chemical industry.Quality as its structural behaviour of cardiac component rotor arrangement of impact breaker plays important effect.And existing rotor arrangement as shown in Figure 1, and its bar 1 ' still adopts the simple plane structure, behind compact heap 2 ' radial compaction, uses locating piece 3 ' location again.This mode is more original, and structure is optimized inadequately, and economy is not good enough.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and the rotor arrangement of a kind of reasonable in design, reliable operation, easy to maintenance, economical and practical impact breaker is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rotor arrangement of impact breaker is characterized in that: comprise rotor, bar, bar fixed block, bar seat pad cover, bar spacer ring; Have rotor recesses on the rotor, bar, bar seat pad cover, bar spacer ring are positioned at rotor recesses; Bar seat pad cover is fixed in the rotor recesses, has the lining groove on it; The one side of bar is fixed with projection, and this projection is installed in the lining groove, and the another side of bar has the bar groove, and bar groove and rotor surround a cavity; The bar spacer ring is positioned at described cavity, and its one side closely contacts with bar, and another side closely contacts with a side channel face of rotor recesses; The bar fixed block is fixed on the rotor, and it closely contacts with the bar spacer ring.

Rotor recesses described in the utility model is the inclined-plane with the side channel face that bar closely contacts.

The utility model also comprises limited block, and limited block is fixed in the lining groove; Have the limited block groove on limited block, projection is installed in the limited block groove.

The utility model compared with prior art has following positive effect: 1, reasonable in design; 2, reliable operation, easy to maintenance, economical and practical.

Description of drawings

Fig. 1 is the part-structure schematic diagram of the rotor arrangement of prior art.

Fig. 2 is the structural representation of the utility model embodiment.

Fig. 3 is the side view of Fig. 2.

Fig. 4 is Fig. 3 A-A cutaway view.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment:

Referring to Fig. 2～Fig. 4, the utility model embodiment comprises rotor 1, bar seat pad cover 2, bar 3, bar spacer ring 4, bar fixed block 5.

Have rotor recesses 11 on the rotor 1, bar 3, bar seat pad cover 2, bar spacer ring 4 are positioned at rotor recesses 11.A side channel face 11a of rotor recesses 11 is the inclined-plane.

Bar seat pad cover 2 is fixed in the rotor recesses 11 by screw, has lining groove 21 on it.

The one side of bar 3 is fixed with projection 6, and projection 6 is as a whole with bar 3.The another side of bar 3 has bar groove 31, and bar groove 31 surrounds a cavity 8 with the side channel face 11a of rotor recesses 11.Projection 6 is installed in the lining groove 21, and as the scheme of optimizing, present embodiment is provided with limited block 7, and limited block 7 is fixed in the lining groove 21; Have limited block groove 71 on limited block 7, projection 6 is installed in the limited block groove 71.That is to say that projection 6 is connected on the limited block 7 on the bar seat pad cover 2 by being connected to.Bar 3 axially limited 7 spacing, prevented bar 3 plaies effectively.

Bar spacer ring 4 inserts in the cavity 8 along the side channel face 11a of rotor recesses 11, and its one side closely contacts with the groove face of bar groove 31, just closely contacts with bar 3, and another side closely contacts with the side channel face 11a of rotor recesses 11.

Bar spacer ring 4 is fixed to the tram by bar fixed block 5.Bar fixed block 5 is installed on the rotor 1 by bolt, nut, and bar fixed block 5 closely contacts with the outer face of rotor 1 near the medial surface of nut end, and rotor 1, bar spacer ring 4 are fixed as one.

During work, rotor 1 sees that on Fig. 4 being clockwise direction rotates, bar groove 31 compresses to bar spacer ring 4 under the inertia force effect, and bar groove 31 can adhere to tiny material and dust, material will directly not beaten on bar 3 like this, but beat on attachment, throw to the counterattack device more at a high speed and carry out once more broken.This special construction of bar 3 not only makes its work safer, reliable, also greatly reduces its rate of wear, also makes whole rotor arrangement have good static and dynamic equilibrium and resistance to impact.When need were changed bar 3, rotor 1 locking anti-rotation was backed out the nut on the bar fixed block 5, takes off bar fixed block 5 and bar spacer ring 4, can easily take off bar 3.

In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
