[0007] Further optimize the technical scheme, the push rod is a convex structure with low sides and high middle.

[0008] Further optimize the technical scheme, the heavy hammer is connected perpendicularly to the rotating shaft.

[0009] Further optimize the technical scheme, the rotating shaft is arranged on the valve through a bearing.

[0010] Further optimize the technical scheme, one end of the connecting rod is hinged to the outer side of the valve plate, and the other end of the connecting rod is fixedly arranged in the middle part of the rotating shaft.

[0011] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is as follows.

[0012] The utility model provides a kind of heavy hammer type self-resetting valve, heavy hammer is connected on valve plate, by setting the push rod of intermediate protrusion on discharge trolley, the rotation of heavy hammer is pushed using push rod, heavy hammer drives valve plate to rotate in the process of rotation, to realize the automatic opening and closing of valve, reduce the labor intensity of staff, can also avoid material waste simultaneously.
