Description

Crushing machine

Technical Field

The utility model relates to a breaker technical field specifically is the breaker.

Background

The hammer crusher is mainly used for crushing materials by means of impact. The material is crushed by the collision surface of the hammer body rotating at high speed and the material, and the material crusher has the characteristics of simple structure, large crushing ratio, high production efficiency and the like, and can crush in a dry mode and a wet mode.

The belt pulley is fixed with hammer crusher's pivot one end in mine, and the other end sets up the counterweight wheel, and the counterweight wheel will self consume a part of mechanical energy to convert into useless work, reduced kibbling efficiency.

SUMMERY OF THE UTILITY MODEL

The technique that exists is not enough to the aforesaid, the utility model aims at providing a breaker, it changes the counter weight wheel into the flywheel dish, also sets up the flywheel dish on the transmission shaft that is close to the belt pulley simultaneously, compares in traditional hammer crusher, can reduce the power loss, increases the power of breaker, improves crushing efficiency.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the crusher mainly comprises a lower shell, an upper shell, transmission shafts, bearing seats, through rods, guard plates, sieve plates, hammer heads and partition plates, wherein the lower shell is connected with the upper shell through a flange;

the transmission shaft is arranged outside one end of the machine shell, a belt wheel disc and a first flywheel disc are respectively arranged on the transmission shaft, and a second flywheel disc is arranged on the transmission shaft outside the other end of the machine shell.

Preferably, the first flywheel and the second flywheel are both located between the housing and the bearing seat.

Preferably, the pulley disc is located outside the bearing seat.

The beneficial effects of the utility model reside in that: through improving current hammer crusher, change the counter weight wheel into the flywheel dish, also set up the flywheel dish on the transmission shaft that is close to the belt pulley simultaneously, compare in traditional hammer crusher, can reduce power loss, increase the power of breaker, improve crushing efficiency.
