Problems solved by technology

The pulley is installed at the lower part of the crushing device, and the weight is heavy, and the replacement process is time-consuming and laborious. Therefore, the crusher in the related art is not convenient to adjust the rotor speed in real time according to the output particle size; maintenance cost
[0007] 3. The motor is connected to the rotating shaft of the crushing device through the transmission belt, and the transmission belt is prone to be too tight or too loose during work.
Too tight will easily cause the transmission belt to heat up and age or even burn out; too loose will cause slippage and motor idling, which will reduce the rotor speed and easily cause material blockage; the shaft of the crushing device is pulled by the transmission belt, increasing the radial load of the bearing on the shaft
Therefore, the bearing is prone to heat and the life of the bearing will be shortened

Abstract

The invention relates to a crushing machine. The crushing machine comprises a vehicle body (1), a crushing device (2) and an engine (3), wherein the crushing device (2) is mounted on the vehicle body(1) and used for crushing materials and comprises a rotary shaft (2a) arranged in the vertical direction, a rotor (2b) coaxially connected with the rotary shaft (2a) and a stop component used for stopping the materials accelerated by the rotor (2b); and the engine (3) is mounted on the vehicle body (1) and is in transmission connection with the crushing device (2). By adoption of the technical scheme, the engine (3) is mounted on the vehicle body (1) and moves along with the vehicle body (1), so that when the working place of the crushing machine is changed, the crushing device (2) can be directly driven by the engine (3) to work, and accordingly, the problem that in the prior art, the working place of a crushing machine cannot be changed easily is solved.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a crusher. Background technique [0002] Crusher is the core equipment used to produce sand and gravel, which is used to break large pieces of material into materials of predetermined particle size. The crushing device of the crusher includes a rotor and a rotating shaft connected with the rotor. The rotor is used to accelerate the material to be crushed, and the accelerated material is crushed in the process of impacting the counter-attack plate and the materials colliding with each other. Adjusting the rotating speed of the rotor can adjust the speed of the material, thereby adjusting the particle size of the crushed material. [0003] The crusher in the related art also includes a car body for carrying the crushing device, and the car body can drive the crushing device to move so as to change the working location of the crusher. The crushing device in the related art is...
