The prior art impact crusher mainly is made up of seven parts such as charging aperture, tripper, crusher chamber, impeller, counterattack liner plate, main shaft assembly, base transmission device and motors.Material is fallen in the impeller of rotation at a high speed by the machine upper vertical, under the effect of high speed centrifugation power, produce high-speed impact and pulverizing with another part with the material of umbrella form shunting around impeller, material is after clashing into mutually, between impeller and many liner plates, form repeatedly mutual bump of eddy current, friction and fragmentation again with material, the straight-through discharge from the bottom, reach desired finished product granularity by screening plant control, the above material of screen cloth returns in the impact cutting broken again again, and it is broken to form closed circuit repeatedly circulation like this.Therefore impact crusher be applicable to soft or in the fragmentation and the shaping of hard and adamant material.The deficiency of prior art impact cutting is: its counterattack liner plate mostly is set to flat, the impact grinding mechanism of its material is " reflecting shape in order " counterattack mode, be that counterattack stream after material impacts thereon concentrates on a direction, be unfavorable for bump repeatedly unordered repeatedly between material and the material, promptly be unfavorable for giving full play to the fragmentation and the shaping feature of impact cutting.

Summary of the invention

The objective of the invention is to promote the fragmentation and the shaping effect of prior art impact crusher, provide a kind of simple in structure, low-cost, crushing efficiency is high, shaping effect is good is equipped with the impact crusher of scattering counterattack liner plate.

In order to reach above purpose, the present invention is achieved by the following technical solutions: a kind of impact crusher that is equipped with scattering counterattack liner plate, comprise frame, frame is provided with charging aperture, tripper, impeller, counterattack liner plate, main shaft assembly, base transmission device and motor, impeller is arranged on the main shaft assembly and with the counterattack liner plate forms the whirling motion crusher chamber, main shaft assembly links to each other with motor by the base transmission device, it is characterized in that, is arranged to the mesh network pore structure on the described counterattack liner plate.

Counterpunch board is the direct benefit that the mesh network pore structure brings and provides the bounce unordered to the material that is come out by the rotor impelling, after material is strikeed back the liner plate bounce-back, be height scattering counterattack state, make the probability that collides mutually between material and the material become higher, fragmentation is more abundant, more effective.

Core technology of the present invention is the Cracking Mechanism that makes the prior art impact crusher, becomes " reflecting shape in order " counterattack into " disordered chain shape " counterattack, makes the bump between material and the material more abundant, more effective.

Remarkable result of the present invention is fragmentation and the shaping efficient that has improved impact cutting.Also brought following beneficial effect simultaneously:

(1) to make that material rebounds in crusher chamber unordered for the counterattack liner plate that has a mesh network pore structure, form a kind of scattering state, make each corner angle of material all be impacted polishing mutually, the material particles of Xing Chenging more is accurate cube and water caltrop and eliminates more fully like this, also is that the shaping feature of impact cutting is more abundant, more effective.

(2) after the mesh network pore structure makes that material forms the scattering counterattack, make the chance of fragmentation between material and the material and shaping more, reduce the wearing and tearing of material, thereby reduced cost the counterattack liner plate.

(3) in the counterattack liner plate manufacture process, carry out the quenching heat treatment operation, promptly to red-hot broken wall immersion water, cool off fast, to reach the purpose of quench hardening heating.The utility model will be strikeed back liner plate and will be provided with thickly dotted reticulated cell group, increase the contact area of quench counterattack liner plate and water greatly, greatly help the quenching degree in the quenching technical, thereby strengthen hardness, wearability and the service life of broken wall.

As preferably, this network structure be by the hexagon mesh form cellular.
