Efficient energy-saving spiral belt silt remover

The invention discloses an efficient energy-saving spiral belt silt remover, and belongs to the technical field of coal mine silt removing equipment. The problems that in the traditional belt conveyorpit coal slime cleaning process, time and labor are wasted, and the environment is polluted are solved. The recycling hopper is arranged below a sweeper on the belt conveyor, the bottom of the recycling hopper is arranged in a closed mode through a U-shaped groove, the shaft spiral blade is horizontally and rotationally installed in the U-shaped groove, the tail end of the shaft spiral blade penetrates through a discharging port formed in the side wall of the U-shaped groove, and a horizontal driving device fixed to a support on one side is used for driving the shaft spiral blade. The vertical driving device is installed on the support on the other side and used for driving the vertically-arranged shaftless spiral blade, the vertical pipe is arranged on the shaftless spiral blade in a sleeved mode, the lower end
