A horizontal spiral feeding device for a vertical spiral coke elevator comprises a charging pipe which is obliquely arranged, wherein the bottom end of the charging pipe communicates a feeding hole ofthe vertical spiral elevator; one side, which is far away from the vertical spiral elevator, of the charging pipe is provided with a horizontal cylinder; the side walls, far away from the vertical spiral elevator, of the horizontal cylinder and the charging pipe communicate with each other through mutually matched oval openings; a spiral conveying auger is arranged in the horizontal cylinder; oneend, close to the vertical spiral elevator, of the spiral conveying auger passes through the oval opening and extends into the charging pipe; one end, far away from the vertical spiral elevator, of the spiral conveying auger is connected with a driving shaft; and a motor for driving the driving shaft and the spiral conveying auger to rotate is arranged outside the horizontal cylinder. According to the device, materials which obliquely fall down to the spiral conveying auger can be driven by the spiral conveying auger to uniformly and smoothly move into the vertical spiral elevator, thus the effect of conveying the materials through the vertical spiral elevator can be ensured, the coke conveying efficiency is improved, and the productivity is saved.
