Double-assembly adjustable pitch mine quarrying machine

Abstract

The invention relates to a double-assembly adjustable pitch mine quarrying machine, comprising an engine base, columns and a saw. The machine is characterized in that a sliding plate with a horizontal guide slot is pivoted on the column guide rail of each column respectively; two ends of gearboxes are pivoted in the horizontal guide slots of the two sliding plates in a sliding manner; synchronouslifting driving mechanisms are pivoted between two sliding plates and the columns at the same side as the two sliding plates; each gearbox is separated into a gear cavity and a cavity; the gear cavity is of a three-shaft structure; the three shafts comprise a motor shaft, an intermediate shaft and an output shaft; the three shafts are subject to meshing transmission by two gear sets; the end faces of motors are fixed at the sides of the gearboxes in a suspending manner; two independent gearboxes of the saw are pivoted on the sliding plates side by side and rotate 180 degrees relative to each other; the motor suspending on the lateral surface of one gearbox can be inserted into the cavity of another gearbox; saw bits arranged on the output shafts of the two gearboxes are arranged at the far sides and are arranged on the same axis; a baffle is fixed between two sliding plates; driving cylinders are respectively arranged between the baffle and two gearboxes; and the positions of the saw bits are adjusted through action of the cylinders.

Description

Technical field: [0001] The invention relates to a mine quarry machine with adjustable distance, in particular to a mine quarry machine which adopts spindle boxes staggered and arranged side by side to save space. Background technique: [0002] Existing mines have generally used mining quarry machinery, which includes a frame that can walk on the mine rail, a lifting frame that carries the saw machine, and a lifting drive mechanism that is pivoted between the frame and the frame. It also includes a motor, a gearbox, and a saw blade fixed on the main shaft of the gearbox, and the output shaft of the motor is connected with the transmission of the gearbox. From a single saw machine with a single saw blade in the early stage, to a single saw machine with multiple saw blades at both ends of the main shaft, and a structure in which two saw machines are combined together, the former has higher requirements for power motors, large volume, The cost is high; the latter is more flexi...

AI Technical Summary

Problems solved by technology

However, the structural design of the combined double-saw machine is unreasonable at present, the position of the saw machine cannot be adjusted, and the shortest distance between the two sets of saw blades can only be 1500mm, which requires a larger base and frame
