Protection mechanism used for mineral weighing sensor

The utility model discloses a protection mechanism used for a mineral weighing sensor. The protection mechanism includes a top cover and a shell. A cavity used for receiving the weighing sensor is arranged in the shell. Data collecting wires are led out via the weighing sensor disposed in the cavity. The side wall of the shell is provided with at least data collecting wire outlet, each being provided with a high-pressure rubber pipe correspondingly. The high-pressure rubber pipes are connected with the data collecting wire outlets through joints and data collecting wire leading-out channels are formed in the directions of the data collecting wire outlets, the joint and the high-pressure rubber pipes. Preferably, the joints are L-shaped and one ends of the joints are connected with the data collecting wire outlets in a plugging manner while the other ends of the joints are connected with one ends of the high-pressure rubber pipes in a plugging manner. By adopting the protection mechanism, the data collecting wires can be prevented being damages when protruding from the shell. The protection mechanism is convenient to assemble and disassemble.
