Abstract

The invention discloses a roadheader and a muck transportation device thereof. The muck transportation device includes a transportation passage for conveying the muck. There is a push mechanism inside the transport channel for pushing the muck out of the gate assembly, and the gate assembly is used to close when the push mechanism is away from the gate assembly to avoid backflow of the muck; the side wall of the transport channel is provided with a gap, the gate The components include gates arranged in the relief gap, and a gate driving mechanism arranged outside the transportation channel and used to drive the gates to move. The muck transportation device provided in the present application uses a gate assembly to block the transportation channel, thereby preventing the muck from flowing back through the gate assembly and ensuring normal transportation of the muck.

Description

technical field [0001] The invention relates to the technical field of shaft construction, and more specifically, relates to a muck transportation device. In addition, the present invention also relates to a roadheader comprising the above-mentioned muck transportation device. Background technique [0002] During the excavation of the vertical shaft, the muck is conveyed from the excavation surface to the tail of the shield through the screw conveyor, and is conveyed to the muck upward transportation channel through the muck storage device, and then the muck is transported upward to the vertical belt conveyor, and then by the vertical The belt conveyor is transported to the ground. During the upward transportation of the muck, how to transport the muck from the tail of the shield to the vertical belt conveyor is the key to transporting the muck out, so it is particularly important to ensure the efficient upward transportation of the muck. [0003] The existing shaft slag c...
