Potash mine double cutter disc angle adjustable structure, method and full-face tunneling machine

Abstract

The application provides a double cutter disc angle adjustable structure, method and full-face tunneling machine suitable for potash salt mine, and relates to the technical field of full-face mechanized mining equipment for solid potash salt mine and other sedimentary layered deposits. The structure comprises two cutter disc assemblies arranged symmetrically left and right, wherein the output end of a main cutting gear box is rigidly connected with the cutter disc; a driving assembly is arranged on the frame of the full-face tunneling machine and is connected with the main cutting gear box; the two ends of an angle adjusting mechanism are respectively connected with the frame and the side wall of the main cutting gear box, and are used for driving the main cutting gear box to rotate around the vertical central axis thereof relative to the frame, so that the cutter disc is inclined outward relative to the tunneling direction in the horizontal plane; and the structure further comprises a controller which is respectively connected in communication with the driving assembly and the angle adjusting mechanism. The double cutter disc is inclined to form a certain outward inclination angle, the active cutting of the ground stress chain and the stress dimension reduction are realized, the rock breaking specific energy is reduced, and the cutting efficiency is improved.
