The invention discloses a rubber belt plate feeder which comprises a frame. Parallel rollers are respectively mounted at the front end and the rear end of the frame. The rubber belt plate feeder further comprises a feed inlet and a discharge outlet which are respectively formed at the front end and the rear end of the frame and a composite conveying belt sleeved on the front roller and the rear roller. The composite conveying belt comprises two layers, the upper layer is a rubber belt, and the lower layer is a chain board. The inner surface of the rubber belt is smooth, and the outer surface of the rubber belt is provided with rubber teeth. Hollows matched with the rubber teeth on the rubber belt are formed in the chain board. By the structure, advantages of a rubber belt feeder and a plate feeder are combined, defects are abandoned, heavy objects with large particle size can be conveyed, and material leakage can be prevented.
