A vertical lifting type drum coal-mining machine without a rocker arm includes a central control box, left and right cutting and lifting reduction gear boxes, left and right guide rail fixing box bodies, left and right traction reduction gear boxes, and left and right traveling gear boxes. The left and right cutting and lifting reduction gear boxes are provided with slideways in fit with lifting guide rails of the left and right guide rail fixing box bodies. Lifting cylinders drive the left and right cutting and lifting reduction gear boxes to make lifting motion. A cutting gear reduction mechanism adopts two-stage fixed-axle gear transmission and two-stage planetary gear transmission, is free from multiple idler pulley groups and has simple transmission chain. The fit between the lifting guide rails and the slideways enables the entire machine to be compact in structure, and the reliability and stability of operation are improved.
