The invention discloses a disc type feeding device. The disc type feeding device comprises an upper cylinder, a lower cylinder, a material guide cover, a disc and an adjusting plate. The upper cylinder and the lower cylinder are connected through a flange. The material guide cover is hung on a top plate of the upper cylinder through a height adjusting hand wheel. The disc is fixed to a main shaft. A discharging port is formed in the bottom of the side portion of the lower cylinder. The adjusting plate is connected with the inner wall of the lower cylinder through a hinge seat. The adjusting plate is obliquely arranged on the disc and the upper portion of the discharging port. The middle portion of the adjusting plate is hinged to the angle adjusting hand wheel, the lower end portion of the main shaft penetrates a bearing box and is connected with a main shaft of a motor. The bearing box is fixed to a bottom plate of the lower cylinder through a screw. The disc type feeding device has the beneficial effects that the application range is wide, energy consumption is low, and stability is good.
