Description
Technical field
The present invention relates to field of cracking machine, and in particular to arrives a kind of tup and crusher.
Background technology
Impact breaker be it is a kind of using impact energy come the crushing mechanism of broken material.Building stones are directly fallen by machine upper portion
Enter high-speed rotating rotor；Using the bar on high-speed rotating rotor, high speed impact is generated to the material being sent into crusher chamber
And be crushed, and make the material being crushed tangentially to throw to the counterpunch board of the crusher chamber other end at a high speed, be broken again, so
It is rebounded to bar, is repeated the above process by counterpunch board again afterwards.Material is on the way, storeroom also has mutual tampering action back and forth；By
It is hit by bar in material, the collision mutual with the impact of counterpunch board and material, material constantly generates crack, pine
It dissipates and causes to crush, when material size is less than the gap between counterpunch board and bar, be discharged from lower end discharge gate.With production energy
The advantages that power is big, and reduction ratio is big, and material is in cube grain after being crushed, granularity is small.
Existing bar is directly fixed on rotor, when the rotor is turning, in addition to needing produced by bearing to impact because of building stones
Impact force outside, it is also necessary to bear generated centripetal force when bar moves in a circle, abrasion is larger, and service life is shorter.By
Larger in the volume of rotor, the cost of replacement is higher, needs one kind to last a long time, the lower tup of use cost.

For the working efficiency of the rotary balance and raising tup of rotor, the quantity of bar can be multiple, the rotor
Periphery is equipped with the bar mounting groove equal with the multiple bar quantity, and the multiple bar is stuck in corresponding bar installation
On slot；Multiple bars are evenly arranged in the periphery of rotor；The multiple bar both ends connect with the bar connecting plate solid respectively
It is fixed.
Embodiment five
Further, the number of bar can be arranged in pairs, i.e., the number of bar is even numbers.It is symmetrical about the rotor axis
Two bars grab between, elastic damping part is provided with, to further increase effect caused by embodiment three.
Embodiment six
Fig. 5 shows the tup enlarged partial sectional view of the embodiment of the present invention, the protrusion and L of specially one of L-type
The sliding slot of type coordinates mounting structure schematic diagram.The bar connecting plate is towards being provided with multiple L-types on the side of the rotor
Protrusion, the rotor correspond on the position of the protrusion, are provided with the sliding slot of L-type；Protrusion direction, the L-type of the L-type
The steering when direction of sliding slot is worked normally with the rotor is opposite；
The protrusion is put into from the notch of the sliding slot, along steering opposite direction twisting when being worked normally with the rotor
The bar connecting plate, the protrusion stick into the corresponding sliding slot, and the bar connecting plate is fixed on the rotor.
When rotor normal rotation works, the L-type protrusion on the bar connecting plate of the embodiment of the present invention and the L-type on rotor
Sliding slot has a certain self-locking function, and is not easy.
Embodiment seven
Further, in order to improve the durability of bar, middle section pair of the bar about the rotor axis direction
Claim, the shock surface and supporting surface of bar are interchangeable, and compared with existing board hammer structure, service life doubles.
Embodiment eight
In specific implementation, in order to improve the service life of bar, the selection of the making material of bar is a critically important link, base
Potassium steel or rich chromium cast iron may be selected in the material of main part of cost consideration, bar, potassium steel or rich chromium cast iron possess preferably resistance to
Mill property, intensity and cost are relatively low, are suitble to the main body of manufacture bar；In order to further improve the service life of bar, can be rushed in bar
Face side is hit, from rotor on exposed face, covering is provided with abrasion-proof ceramic coat.
Wear-resistant ceramic is with AL2O3It is roasted through 1,700 degree of high temperature using rare metal oxide as flux for primary raw material
Extraordinary corundum ceramic made of burning, then the product that is composed respectively with the organic/inorganic adhesive of specific rubber and high intensity,
It is big with hardness, wear-resisting property is fabulous, light-weight, bonding securely, the good characteristics such as heat resistance is good, but very due to its cost
Height, bar integrally cannot be all using wear-resistant ceramics as material.
For the stressing conditions of bar, the thickness of abrasion-proof ceramic coat gradually increases outward along rotor radius direction, and
The outermost of bar reaches maximum value.
Embodiment nine
Fig. 6 shows the utility model embodiment impact breaker.The utility model embodiment additionally provides a kind of anti-
Impact crusher, the tup in the impact breaker are the tup described in embodiment one to embodiment five.
In actual motion, high speed rotation, building stones enter reaction type from feed inlet 1000 and break tup 1001 in the counterclockwise direction
Broken machine inner cavity is in contact with the bar of 1001 rightmost side of tup first, and part building stones are smashed when being in contact with bar, stone
Material is all moved toward the counterpunch board of surface 1002；When striking counterpunch board 1002, part occurs to be crushed building stones, then again anti-
On bullet to tup 1001；And so on, final building stones are crushed into the less small building stones of size.
The centripetal force of tup and crusher provided by the invention, the bar of the tup is carried by the bar connecting plate of rotor both sides
For the bar mounting groove stress of rotor is reduced, and the service life increases；Bar connecting plate carries out the limit of bar by the way of structure limit
Position, installation steps are simpler；Bar connecting plate is fixed on based on self-locking structure on rotor, and efficiency of assembling is higher.
It is provided for the embodiments of the invention a kind of tup above and crusher is described in detail, it is used herein
Principle and implementation of the present invention are described for specific case, and the explanation of above example is only intended to help to understand this
The method and its core concept of invention；Meanwhile for those of ordinary skill in the art, according to the thought of the present invention, specific
There will be changes in embodiment and application range, in conclusion the content of the present specification should not be construed as to the present invention's
Limitation.
