Tunneling machine and muck discharging device thereof

The invention discloses a tunneling machine and a muck discharging device thereof. The muck discharging device comprises a winch and a belt machine used for conveying muck to the outside from the inside of a vertical shaft. The belt machine comprises a conveying belt, a machine head arranged on a supporting platform outside the vertical shaft, a machine tail located in the vertical shaft, and a first steering portion enabling the conveying belt to be steered from the outside of the vertical shaft to the inside of the vertical shaft. The machine tail is fixed to the tunneling end of the tunneling machine through a tail frame. The winch is connected with a moving support of the machine head through a steel wire rope. In the tunneling process of the tunneling machine, the machine tail of thebelt machine moves in the tunneling direction along with the tunneling machine, meanwhile, the winch releases the steel wire rope synchronously, the machine head of the belt machine moves to a shaft opening of the vertical sh
