[0018] As shown in Figure 1 , 2 , the belt 2 is provided with a weighing device below, and the weighing device is arranged at the lower end of the upper belt 2, and the weighing device comprises a pressure sensor support which is mounted on the rack 1, and the pressure sensor support is provided with a weighing supporting roller which is in contact with the lower surface of the belt 2, and the weighing supporting roller is provided below with a pressure sensor, and the pressure sensor can detect the pressure borne by the weighing supporting roller, and when the belt 2 carries the materials and moves to the weighing supporting roller, the gravity of the materials applies a downward force to the weighing supporting roller, and the weighing of the materials is completed through the detection of the pressure sensor. When the materials move to the upper side of the weighing device, the weight of the materials passing through the weighing device on the belt 2 can be weighed by the weighing device. In the embodiment, the height of the upper end of the weighing supporting roller is higher than the upper ends of the driving roller 31 and the driven roller 32, so as to avoid that the supporting force of the belt 2 on the materials affects the weighing result of the materials, and the accuracy of the weighing of the materials is ensured.

[0019] As shown in Figure 1 , 2 , a speed measuring device is arranged at the driven roller 32, and the speed of the driven roller 32 is measured through the speed measuring device, and then the rotating speed of the belt 2 is known, and then the total amount of the materials transported to the discharge end by the belt 2 within a certain time is known. The speed measuring device comprises a coupling disc and an encoder which are mounted on the main shaft of the driven roller 32, and the rotating angle of the driven roller 32 is converted into distance through the encoder, and then the moving distance of the belt 2 is known.

The contact area between the active roller 31 and the belt 2 is large, and the iron impurities can be adsorbed on the belt 2. In other embodiments, an iron removal block can also be provided on the rack 1 to adsorb the iron impurities in the material. Compared with the iron removal block, the active roller 31 is provided with strong magnetism, which ensures the iron removal effect and facilitates the collection of iron impurities.
