Inertia cone crusher

Abstract

The invention discloses an inertia cone crusher. The inertia cone crusher comprises a bottom frame. A belt transmission device is arranged in the middle of the lower end of the bottom frame, a movable cone is arranged above the belt transmission device, a movable cone shaft is installed in cooperation with a shaft sleeve, a vibration exciter is fixedly installed on the side face of the shaft sleeve, a movable cone head is supported by a movable cone supporting base, a spherical bush is installed between the movable cone supporting base and the lower side face of the movable cone head in cooperation, a liner plate is installed on the inner side conical face of a fixed cone in cooperation, a shell is located above the bottom frame, a rubber pad is installed between the shell and the bottom frame, and the movable cone supporting base makes contact with the shell. No rigid connection exists between the movable cone and a transmission mechanism, damage to the movable cone caused by overload of extrusion stress is prevented, counter-acting force borne by the spherical bush can be counteracted by the shell and the rubber pad together to a certain extent, the work environment of the spherical bush is greatly improved, and the whole device is simple in structure, convenient to operate, high in efficiency and high in work reliability.

Description

technical field [0001] The invention relates to the technical field of crusher manufacture, in particular to an inertia cone crusher. Background technique [0002] At present, most inertial cone crushers use a motor to directly drive the shaft of the moving cone. Under the action of the counterweight, the cone is driven to do a swinging motion to crush the material. When subjected to a large extrusion stress, the moving cone is easy to break away from the bearing bush, or even roll over. , In addition, the impact force generated between the bearing bush and the moving cone has no place to offset, making the two contact surfaces very easy to damage, and destroying the supporting effect of the bearing bush on the moving cone and the main shaft. Therefore, we propose an inertial cone crusher. Contents of the invention [0003] The purpose of the present invention is to provide an inertial cone crusher to solve the problems raised in the above-mentioned background technology. ...
