A chain belt type feeding machine is most suitable for feeding mineral materials and feeding materials into stock bins of other bin storage departments and comprises a connecting groove, a guide groove, a driving chain wheel set, a buffer carrier roller, a rack, a tension chain wheel set, a manual gate, a driving device and a roller, wherein the driving chain wheel set and the tension chain wheel set are respectively provided with a closed annular chain belt driven by the driving chain wheel set; each closed annular combined chain belt is formed by combining a plurality of Y-shaped chain blocks with two groups of roller chains; the Y-shaped chain blocks are connected in series by a pin roll; the upper surfaces and the lower surfaces of the Y-shaped chain blocks are respective planes; the two groups of roller chains are respectively arranged on two sides of the closed annular combined chain belt; the manual gate comprises a hand wheel, a chain driving device, a pin tooth driving device and a gate door panel; and a sweeping mechanism for clearing the annular combined chain belts is arranged on one side of a discharge opening of the rack. The feeding machine has the advantages of compact structure, small size, light weight, accurate driving position, small driving wear, high production efficiency and long service life; and the influence of the feeding stability due to driving skidding of the belt type feeding machine belt can be eliminated and the phenomenon that the feeding machine cannot thoroughly discharge can be prevented.
