The invention belongs to the technical field of conveying and feeding and particularly relates to a novel feeding device comprising a shell, inspection ports, a feeding inlet, spiral conveyors, abrasion resistant layers, a bridging prevention device, driving devices, pneumatic conveying pipes, spraying openings and air inlets. The inspection ports and the feeding inlet are formed in the shell; thespiral conveyors are arranged in the shell; the abrasion resistant layers are arranged in the positions, below the spiral conveyors, in the shell; the bridging prevention device is arranged on the feeding inlet; the driving devices are arranged at one end of the shell and connected with the spiral conveyors for providing power for the spiral conveyors; the pneumatic conveying pipes are arranged at the other end of the shell and connected with the spiral conveyors through adapting openings, and receiving openings of the pneumatic conveying pipes are connected with outlets of the spiral conveyors; the spraying openings are formed in the upper portions of the pneumatic conveying pipes; and the air inlets are connected to the upper portions of the spraying openings through flexible connectors. The novel feeding device has the advantages that the structure is simple, material conveying adaptability is wide, bridging is not liable to occur, the feeding amount is stable and controllable, continuous operation can be achieved, the conveying amount is large, arrangement is convenient, and the operation environment is excellent.
