Abstract
The utility model provides a hydraulic weighing sensor for a measuring hopper with structure optimization. The structure of the hydraulic weighing sensor for the measuring hopper comprises a height adjusting column, a piston, inner press rings, flexible films, a shield, outer press rings, a guide sleeve, a pressure transmitter, a junction box protective housing, a base plate, a guide bar, a venting screw plug, bolts, an adjusting handle and the like. Liquid oil is disposed in enclosed space which is composed of the piston, the guide sleeve, the flexible films, the venting screw plug, the pressure transmitter and the like. When the piston of the hydraulic weighing sensor is subjected to the action of gravity of a skip bucket or other tested objects, the liquid oil pressure in enclosed space around the piston is increased, the degree of increase in the liquid oil pressure is in direct proportion to an active force received, and a variable value of the pressure is measured by the pressure transmitter, so that the weight of coal or other objects in the tested skip bucket is measured and a function of weighing is realized. The hydraulic weighing sensor is simple and firm in structure, easy to manufacture, large in measuring range and long in service life, and can adapt to hostile environments.
