Abstract
The utility model discloses an automatic multi-point hydraulic weighing sensor balancing device comprising a plurality of hydraulic weighing sensors and a hydraulic pressing device. The plurality of hydraulic weighing sensors are mounted on the same measuring hopper to joint measure the weight of the same measuring hopper. Hydraulic cylinders of the plurality of hydraulic weighing sensors are mutually communicated through multiple liquid transmission branch pipelines and are connected with the hydraulic pressing device through the same liquid transmission total pipeline. The corresponding liquid transmission branch pipeline of each hydraulic weighing sensor is provided with a hydraulic valve. By the abovementioned method, the automatic multi-point hydraulic weighing sensor balancing device utilizes the plurality of hydraulic weighing sensors to joint bear force, so that a phenomenon that a single hydraulic weighing sensor is easy to break when bearing force independently is prevented, and the weighing scale is enlarged. In addition, the hydraulic cylinders are mutually communicated, and by the theory of a hydraulic communicating vessel, a phenomenon that a plurality of load-bearing sensors are easy to break due to uneven stress is prevented.
