Buffer hopper dredging opening and closing device for static weighing system

The utility model discloses a buffer hopper dredging opening and closing device for a static weighing system, which comprises a buffer hopper arranged between a screw elevator and a weighing hopper, an opening communicated with the outside is arranged on the front surface of the buffer hopper, and a buffer hopper opening and closing door is hinged at the opening of the buffer hopper through an opening and closing door fixing hinge, and the size of the buffer hopper opening and closing door is matched with that of the opening. According to the buffer hopper dredging opening and closing device for the static weighing system, when the buffer hopper is blocked, materials can be quickly cleaned and dredged through the buffer hopper opening and closing door without knocking the outer wall of the buffer hopper, so that the fault processing efficiency can be effectively improved, and the phenomenon that the materials are blocked due to tight sealing of the buffer hopper is avoided. The outer wall of the buffer hopper
