Problems solved by technology

Existing cone crushers are all equipped with a hydraulic lifting mechanism at the lower end of the moving cone, so as to adjust the axial height of the moving cone group; however, the control accuracy of the size of the crushing chamber under this structure is not high, and the maintenance of the large hydraulic lifting mechanism The cost is too high; the top frame of the cone crusher with the fixed cone cannot be adjusted axially, so there is an urgent need for a cone crusher top frame that can change the axial height of the fixed cone

Abstract

The invention relates to the field of mining equipment and particularly relates to a top frame of a cone crusher. The top frame of the cone crusher comprises a connecting frame and a fixed cone frame which is positioned in the connecting frame and is in threaded connection with the connecting frame, wherein a driving ring large gear ring is arranged on the outer side surface of the fixed cone frame, and the driving ring large gear ring and the fixed cone frame are positioned in the circumferential direction and not positioned in the axial direction; a regulating motor for driving the driving ring large gear ring and a large gear ring support seat for axially positioning the driving ring large gear ring are arranged on the connecting frame; and a pair of rolling wheels which are aligned in the longitudinal direction is arranged at the upper end part of the large gear ring support seat, the driving ring large gear ring is clamped between the two rolling wheels, and the regulating motor is in transmission and connection with the driving ring large gear ring. The top frame of the cone crusher can change the axial height of a fixed cone so as to adjust the size of a crushing cavity between a moving cone and the fixed cone.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher top frame. Background technique [0002] Cone crusher is a kind of mining machinery used for crushing stones. Its working principle is to crush stones through the mutual cooperation between the movable cone and the fixed cone that rotates through the swing; Crushing chamber; in order to produce stones of different sizes, the cone crusher needs to change the size of the crushing chamber between the movable cone and the fixed cone. Existing cone crushers are all equipped with a hydraulic lifting mechanism at the lower end of the moving cone, so as to adjust the axial height of the moving cone group; however, the control accuracy of the size of the crushing chamber under this structure is not high, and the maintenance of the large hydraulic lifting mechanism The cost is too high; while the top frame of the cone crusher equipped with the fixed cone cannot be adjusted a...
