[0018] Through the above-mentioned arrangement, when the belt scale is assembled and combined with the conveyor belt 10, the base 1 is installed and fixedly connected to the internal bracket of the conveyor belt 10. During the adaptation process, the spacing of the support sprocket 5 is changed by adjusting the left and right screws 11 to adapt to the width of the conveyor belt 10, and the stabilizing toothed disc 6 stabilizes the chain 7. A plurality of support beams 8 form a weighing support area under their own weight and the pressure of the conveyor belt 10, and cooperate with the bottom of the conveyor belt 10 through the rollers 9 on the surface to reduce the working resistance of the conveyor belt 10. In addition, the cross-sectional shape of the weighing area can also be realized according to the tightness of the chain 7, so as to adapt to the roller system of the conveyor belt 10.
