Master stream balance weighing device

The utility model provides a master stream balance weighing device belongs to feed production technical field. It has solved the problem that the surrounding environment can influence master stream balance precision. This master stream balance weighing device includes the box, still include weighing plate, the connecting plate of weighing, the sensor connecting rod, bellows torque sensor, the box includes flange and lower flange, upward be equipped with feed inlet and discharge gate on flange and the lower flange respectively, weighing plate connects on the connecting plate of weighing, the connecting plate of weighing is connected on the sensor connecting rod, the sensor connecting rod is connected to on the bellows torque sensor, bellows torque sensor connects on the box, bellows torque sensor and outside pressure detection meter box passing signal line connection. The material gets into the back and impactes on weighing plate, and bellows torque sensor experiences the material stream back that weighing plate went up the material, gives the pressure detection meter box with information transfer. Control and catch the grease by the pressure detection meter box again, adopt bellows torque sensor, it is insensitive relatively to disturbing the momentum.
