The invention has the essentials that the box body of a cutting speed reducer is connected with the retractable section of the cutting head through two hydraulic cylinders; the cutting head is provided with a special water channel of high pressure water; a shovel board, a first conveyer, a connecting bar and a back support are connected sequentially in an articulated mode to form a four-bar mechanism; and the body is divided into a front body frame and a back body frame from the middle. The invention is beneficial to underground transport and installation and improves the utilization rate of the underground tunneling machine. |
