Adjustable stable jaw crusher

Abstract

The invention belongs to the field of mining, and particularly relates to an adjustable stable jaw crusher which comprises a rectangular pyramid funnel, a machine case, a motor, a first gear, a secondgear, a third gear, a fourth gear, a gear moving mechanism, a pull rod mechanism, a movable jaw plate mechanism and the like. When the motor rotates, the motor drives the second gear, the third gearand the fourth gear to rotate through the first gear, and the second gear sequentially drives the movable jaw plate mechanism to grind stone blocks through the gear moving mechanism and the pull rod mechanism; meanwhile, nail teeth on the movable jaw plate mechanism rotate; when larger or harder stone blocks need to be crushed, the stone bocks can act on the movable jaw plate mechanism, and the movable jaw plate mechanism acts on the gear moving mechanism through an air pipe, so that a fifth gear moves along a sliding chute to a position meshing with the fourth gear; the rotating speed of thefifth gear is reduced, and the torque is increased; and an action force of the movable jaw plate mechanism on the stone blocks is increased, so that the larger or harder stone blocks can be easily crushed.

Description

technical field [0001] The invention belongs to the field of mining, in particular to an adjustable and stable jaw crushing equipment. Background technique [0002] At present, the traditional jaw crushing equipment is driven by a motor to drive the belt and the pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the jaw plate closer to the fixed jaw plate. At the same time, the material is crushed to achieve the purpose of crushing; when encountering large or hard stones, the traditional jaw crushing equipment cannot crush the stones well, resulting in the phenomenon of machine jamming; this not only reduces the work It will also cause damage to the internal parts of the motor and crushing equipment, thereby increasing production costs. [0003] The present invention designs an adjustable stable jaw crushing equipment to solve the above ...
