In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a take hammer crusher reaction plate of damping spring, includes damping spring, reaction plate, connecting bolt, connecting plate, reaction plate and connecting plate, damping spring pass through connecting bolt rotation link together, reaction plate installs at the connecting plate top, the connecting plate is installed at damping spring top.
Preferably, the impact plate with the vibration reduction spring is detachable, the impact plate, the connecting plate and the vibration reduction spring are connected together through a plurality of connecting bolts, and the screw is screwed out when the impact plate is required to be detached, so that the impact plate is convenient to clean and maintain when the work is finished;
preferably, when the impact plate with the vibration reduction spring impacts materials at a high speed, the vibration reduction spring is stressed to deform, so that the cavity space is enlarged, and the hammer crusher can be better adapted to materials with different particle diameters;
preferably, the impact plate, the connecting plate and the damping spring are rotationally connected together through a plurality of connecting bolts, so that when the hammer crusher operates, the connecting bolts cannot loosen due to high-speed impact of materials to cause the impact plate to fall off, and the stability is improved;
preferably, the damping spring is made of oil quenching tempering silicomanganese material, the material has high strength and good performance, meets the bearing force required by high-speed material impact on the impact plate, and can elastically deform to absorb the energy generated by material impact, thus playing a role in buffering and damping;
preferably, the impact plate is made of a medium carbon alloy steel material, has enough wear resistance and strength to bear the impact and abrasion of materials, and ensures that the impact plate is not easy to wear or deform in the long-time use process;
preferably, the impact plate is in a zigzag shape, so that impact force from materials can be dispersed, and the impact force is prevented from being excessively concentrated in a specific area of the crusher;
preferably, the connecting plate is made of high-strength steel, has enough bearing capacity and plays a bearing role between the impact plate and the damping spring;
compared with the prior art, the impact plate, the connecting plate and the damping spring are connected through the connecting bolts, when the ore is hit by the hammer head and impacts the impact plate, the damping spring provides a buffering effect, reduces the vibration of the hammer crusher body, weakens the damage of the vibration to the hammer crusher body, and prolongs the service life of the hammer crusher. The damping spring installed at the bottom of the impact plate can generate compression when being subjected to external force, so that the limitation of the impact plate to the cavity space is reduced, ores with different particle sizes can be adapted, the situation that the ores are blocked between the cavity and the hammer is avoided to a certain extent, and the working efficiency is improved.
