Abstract

The invention belongs to the technical field of weighing instruments, and discloses a material yard hopper scale with high accuracy. The hopper scale includes a weighting assembly and a calculating assembly used for calculating weighing results; the weighting assembly includes a weighing bucket, weighing sensors, pedestals and a servo motor; the bottom of the weighing bucket is provided with the weighing sensors; the weighing sensors are connected to a storage module and used for transmitting weighting data to the storage module to store; the bottom of the weighing bucket is provided with the servo motor; the servo motor is in clamp connection with the weighing bucket; and the bottom of the servo motor is provided with a hydraulic air cylinder used for jacking up the weighing bucket. Multi-time measuring can be performed after the servo motor rotates same angles until the servo motor rotates a circle, meanwhile, the storage module can transmit measuring results to an operation module to perform calculating, so that the mean value of the measuring results can be obtained; and through the measuring of the material center of gravity at the internal of the balance weighing bucket by rotating for many times and the measuring and calculating of the mean value for many times, errors generated by weighing can be greatly reduced, and the weighing precision of the hopper scale can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of weighing instruments, and in particular relates to a stockyard hopper scale with high accuracy. Background technique [0002] The hopper scale is a weighing electronic scale used to measure the weight of the material in the hopper. It is mainly composed of weighing bucket, bracket, pneumatic valve, high-precision weighing sensor, junction box, signal cable and intelligent weighing display screen. [0003] The hopper scale is weighed through the load cell at the bottom. When the material inside the hopper is not evenly arranged, that is, when the center of gravity of the material inside the hopper is shifted, it will cause an error in the weighing of the material, which will greatly affect the hopper. The accuracy of the scale. Contents of the invention [0004] The invention provides a hopper scale with high accuracy, which aims to solve the problem that the hopper scale is weighed through the weighin...
