The invention discloses a belt-type double-layer efficient conveyor. The conveyer comprises a base, one side of the front surface of the base is fixedly connected with a power supply box, and the other side of the front surface of the base is fixedly connected with a control box; a storage box is fixedly connected to the side of the top surface of the base, and the other side of the top surface ofthe base is provided with a feeding box through a fixing base; a double-layer conveying belt is fixedly connected between the feeding box and the inner side of the fixing base through a mounting frame, and a speed sensor and a pressure sensor are sequentially installed on one side of the bottom of the double-layer conveying belt; the double-layer conveying belt covers the surface of a belt tensioning roller arranged between the inner side walls of the mounting frame, and a rotating shaft is arranged at the two ends of the belt tensioning roller; a servo motor is fixedly connected with the position, in the center of the front surface of the mounting frame, on the right side of the rotating shaft. According to the conveyer, the belt tensioning roller, the speed sensor and the pressure sensor structure are arranged, so that the conveyer has the advantages of achieving automatic quantitative material conveying, being efficient and reducing the cost.
