Abstract

The invention provides an automatic adjusting device for discharging granularity of a jaw crusher. The adjusting device comprises a direct current reducing motor, a driving gear, a driven gear, a square-head bolt, an adjusting wedge and a supporting seat. An output shaft of the direct current reducing motor is connected to the driving gear, the driven gear is engaged to the driving gear, and the upper end of the square-head bolt is fixed to the driven gear and the lower end of the square-head bolt penetrates the adjusting wedge and is in threaded fit connection to the adjusting wedge; the side, close to a toggle plate, of the adjusting wedge is an inclined surface, and the side, close to the toggle plate, of the supporting seat is connected to the toggle plate through a connecting rod while the other side of the supporting seat leans against the inclined surface of the adjusting wedge. The granularity automatic adjusting device provided by the invention drives the square-head bolt andthe adjusting wedge to move in a reciprocating manner by means of intermittent forward and backward rotation of the motor to further drive the supporting seat slidably matched with the adjusting wedgeto move left and right to adjust the size of a discharge port of the crusher so as to meet the demand of adjusting the discharging granularity.

Description

technical field

[0001] The invention relates to a device for automatically adjusting the discharge granularity of a jaw crusher. Background technique

[0002] At present, the jaw crusher used in the preparation industry of mineral products (coal, coke, iron ore, ferroalloy, etc.) is a kind of equipment used to complete material crushing. The jaw group and the fixed jaw frame bite each other to simulate the movement of the two jaws of the animal, so as to crush the material; in order to obtain mineral materials with different particle sizes, the size of the discharge port needs to be adjusted; in addition, with the jaw crusher jaw plate Due to the continuous wear and tear, the clearance of the discharge port is also constantly changing, so the particle size also changes accordingly. In order to ensure the requirements of the crushing particle size, it is necessary to frequently adjust the size of the discharge port.
