The invention relates to the technical field of mechanical conveyance, in particular to a weighing ridge-shaped belt conveyor. The weighing ridge-shaped belt conveyor comprises a belt conveyor body, and the belt conveyor body is provided with two conveying layers; the first conveying layer is arranged at the upper portion of the belt conveyor body and comprises three conveying belts, and the three conveying belts form a ridge shape; the second conveying layer is arranged below the first conveying layer, and a feeding guide prot is formed in the inlet direction of the second conveying layer; a material baffle is arranged above the first conveying layer; a discharging device is arranged above the material baffle and comprises a feeding port, an overhauling door, a batching door and an aggregate weighing device, wherein the feeding port is formed in a discharging port of a production instrument, the overhauling door is arranged below the feeding port and communicates with the batching door, and connecting ports are formed in the outer side of the aggregate weighing device and are connected under the batching door in a suspended mode through connecting arms. According to the weighing ridge-shaped belt conveyor, the material can be weighed and then conveyed, the material leakage cannot be generated in the conveyance process, and the labor force is saved.
