The invention relates to a belt-type conveying mechanism for traditional Chinese medicines. The belt-type conveying mechanism comprises wheels, a redirection roller, a frame, a conveying belt, a side retaining belt, a side clamping mechanism, an upper supporting roller, conveying belt bumps, an unloading funnel, a motor, a connecting shaft, a decelerator, a fixing shaft and a transmission roller. The conveying belt bumps are arranged on the conveying belt at intervals, the traditional Chinese medicines can be directly placed on the conveying belt and driven by the transmission roller to enter the unloading funnel, the conveying belt running to the lower portion does not need a lower supporting roller, and running of the conveying belt bumps cannot be affected by the aid of the side clamping mechanism. The traditional Chinese medicines can be sufficiently transmitted to the top end from the lower end by the conveying belt, and the belt-type conveying mechanism is simple in design, convenient to operate and applicable to conveying the traditional Chinese medicines.
