[0030] It should be noted that in the process of lifting the rod-shaped counterweight 102, the two arc-shaped supporting plates 402 are respectively inserted into the two second annular positioning grooves 5 of the rod-shaped counterweight 102, and through the interaction between the two arc-shaped supporting plates 402 and the second annular positioning grooves 5, the rod-shaped counterweight 102 can be kept in a horizontal and centered state during lifting.

[0036] It should be noted here that the belt and the driving device for belt conveying are conventional operating components in the technical field of belt scales, and are used as prior art in the present application without further elaboration.

[0037] Working principle: In the process of using the belt scale, the belt for conveying materials is installed on the idler 803 of each group of bearing assemblies. After the belt is installed, the materials are placed on the belt, and the belt moves at a constant speed under the action of the external driving device, conveying the materials from the feeding end to the discharging end. When the materials pass through the bearing assembly, the bearing and connecting action of the mounting bracket 801, the support bracket 802 and the idler 803 transmits the weight of the materials to the load cell 702 through the load beam 2, and the load cell 702 weighs the weight of the conveyed materials.

[0038] During the use of the belt scale, the rod-shaped weight 102 is used periodically to verify the belt scale. During the verification, the rod-shaped weight 102 is lowered by the lifting assembly. During the lowering process, the rod-shaped weight 102 is placed on the bearing hole 303 of the two groups of support plates 301, and the arc-shaped supporting plate 402 on the lifting assembly no longer lifts the rod-shaped weight 102, so that the weight of the rod-shaped weight 102 acts on the two groups of support plates 301, and is transmitted to the load cell 702 through the connecting action of the mounting seat 302 and the load beam 2. By comparing the change of the weight detected by the load cell 702 with the actual weight of the rod-shaped weight 102, the accuracy of the belt scale during weighing is verified. After the detection is completed, the rod-shaped weight 102 is lifted by the lifting assembly, so that the rod-shaped weight 102 no longer abuts against the bearing hole 303 of the support plate 301.

[0039] During the lifting of the rod-shaped weight 102, the two arc-shaped supporting plates 402 are respectively inserted into the two second annular positioning grooves 5 of the rod-shaped weight 102, so that the rod-shaped weight 102 remains horizontal and centered during the lifting process. During the process of placing the rod-shaped weight 102 into the bearing hole 303, the two groups of support plates 301 are respectively clamped into the two first annular positioning grooves 6 on the rod-shaped weight 102, so that the rod-shaped weight 102 remains horizontal and centered during the verification process, so that the force is uniform during the verification process, and the accurate detection and verification operation of the belt scale is facilitated.
