Novel metering mechanism

The utility model provides a novel metering mechanism which comprises a metering container, and the lower portion of the metering container is arranged on a supporting structure through a pressure sensor. Wherein one end of the feeding and discharging common pipe is inserted into the metering container, and the other end of the feeding and discharging common pipe is connected with a three-way pipe; the upper port of the three-way pipe is connected with the feeding pipe through the feeding valve, and the lower port of the three-way pipe is fixedly connected with the discharging pipe through the discharging valve. According to the utility model, the metering error caused by poor repeatability of the flexibility and the elastic force of the hose is solved, and meanwhile, the weighing accuracy is also improved; and on-site installation of various forms is convenient. 本实用新型提供一种新型的计量机构，包括计量容器，计量容器的下方通过压力传感器设置在支撑结构上；其中所述进出料共用管的一端插入所述计量容器内且另一端连接三通管；所述三通管的上端口通过进料阀门与进料管连接且下端口通过出料阀门与出料管连接固定。本实用新型解决了柔性与软管弹力重复性差而导致的计量误差，同
