Impact crusher

Abstract

The invention discloses an impact crusher. The impact crusher comprises a machine body consisting of an upper machine body and a lower machine body, wherein a rotor is arranged in the machine body; a cover plate is connected to the inner sides of the upper machine body and the lower machine body; an impact plate body set of which one end is movably connected to the cover plate and the other end is connected to the inner side of the machine body through a discharging granularity adjusting mechanism is at least arranged on the cover plate; an opening allowing the impact plate set to be replaced and a head cover matched with the opening are arranged on the cover plate, one end of the head cover is movably connected to the cover plate, and the other end of the head cover is connected to the inner side of the machine body through an uncovering mechanism. The impact crusher can quickly adjust the positions of impact plates to further adjust the discharging gap, brings more convenience for replacing the impact plates, improves the crushing efficiency, and reduces the accident risk.

Description

technical field [0001] The invention relates to crushing equipment, in particular to an impact crusher. Background technique [0002] At present, conventional impact crushers on the market are composed of a body, a rotor, an impact plate body, and a pulley. When working, the motor drives the belt pulley to drive the rotor to rotate at a high speed to hit the material. The material collides with the impact plate body under the impact of the blow bar on the rotor. After multiple blows and collisions, the material that meets the particle size requirements is discharged from the bottom of the machine. [0003] However, there are many problems in this type of crusher. For example, because the impact plate is a vulnerable part, it needs to be checked and replaced from time to time. When the impact plate or blow bar is worn out, the discharge gap needs to be adjusted. At this time, the machine can only be adjusted manually. It is realized by adjusting the bolts at the top, but the...

Problems solved by technology

[0003] However, there are many problems in this type of crusher. For example, because the impact plate is a vulnerable part, it needs to be checked and replaced from time to time. When the impact plate or blow bar is worn out, the discharge gap needs to be adjusted. At this time, the machine can only be adjusted manually. It is realized by adjusting the bolts at the top, but the adjustment is very laborious due to the heavy weight of the counter-attack board; in addition, when the counter-attack board is scrapped and needs to be replaced, only by loosening the connecting bolts and pulling upwards by external force can the upper body be separated, and the counter-attack board body The outflow gap is separated, and workers then replace it

As a result, it is difficult and time-consuming to adjust or replace the impact plate, and the external factors are unstable due to the small working gap and inflexible work, and safety accidents are prone to occur
