[0002] In the process of silicon material processing, quartz tubes are generally used for feeding. During the feeding process, the feeding amount of silicon material needs to be controlled. Since the silicon material needs to be put into the crucible of the single crystal furnace for crystal growth and pulling out wafer rods, the weight of the silicon material in the single crystal furnace needs to be appropriate. Too much silicon material will cause overflow and explosion, resulting in production accidents. Too little silicon material will cause the single crystal furnace to shut down abnormally and affect the quality of the crystal rods. Therefore, a device that can weigh the silicon material entering the hopper is needed to ensure the accuracy of the feeding weight. The weighing device in the prior art is arranged at the bottom of the feeding device as a whole. When weighing, the feeding device will be offset and tilted according to the feeding direction.
