Adjustable jaw crushing equipment

Abstract

The invention belongs to the field of mining and in particular relates to adjustable jaw crushing equipment. The adjustable jaw crushing equipment comprises a rectangular pyramid shaped funnel, a bodyshell, a motor, a first gear, a second gear, a third gear, a fourth gear, a gear moving mechanism, a connecting rod mechanism, a crushing disc mechanism and the like. When the motor rotates, the motor drives the second, third and fourth gears to rotate through the first gear; the second gear drives the crushing disc mechanism to grind stone blocks successively through the gear moving mechanism and the connecting rod mechanism; when the adjustable jaw crushing equipment comes across relatively large or relatively hard stone blocks, the stone blocks will be acted to the crushing disc mechanism,and the crushing disc mechanism is acted to the gear moving mechanism through a gas pipe, so that a fifth gear moves to a position engaged to the fourth gear along a chute; the rotating speed of thefifth gear is reduced and the torque is increased; and the acting force of the crushing disc mechanism to the stone blocks is increased, so that the relatively hard stone blocks are more easily crushed.

Description

technical field [0001] The invention belongs to the field of mining, in particular to an adjustable 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 jaw crushing equipment to solve the above problems. Conten...
