The adjustment assembly 3 includes a mounting groove 301, an outer protective sheet 302, a hydraulic gas rod 303, a connecting plate 304 and cutting teeth 305. The outer protective sheet 302 is installed on the outer side of the mounting groove 301. The outer protective sheet 302 plays an external protection role between the connecting plate 304 and the mounting groove 301. A hydraulic gas rod 303 is arranged inside the outer protective sheet 302. The hydraulic gas rod 303 drives the connecting plate 304 and the cutting teeth 305 to extend and move outward for adjustment. At the same time, a connecting plate 304 is installed on the output end of the hydraulic gas rod 303. The surface of the connecting plate 304 is installed with cutting teeth 305. After 305 extends outward and moves away from the center point of the cutting drum 1, the spacing of the cutting teeth 305 can be adjusted. The spacing of the cutting teeth 305 is adjusted by controlling the telescopic length. A support arm 4 is installed on the rear side of the middle part of the cutting drum 1 through a rotating shaft, and a coal mining machine body 5 is installed on the lower end of the support arm 4.
