On a limit shaft 10, two weighing sensors 15 are provided, and one weighing sensor 15 is fixedly connected to the top end of the right wing valve 14, and the other weighing sensor 15 is fixedly connected to the top end of the left wing valve 16, and the top of the weighing sensor 15 is flush with the right wing valve 14 and the left wing valve 16, and two second limit shafts 17 are provided, and one second limit shaft 17 is fixedly connected to the middle of a side of the right wing valve 14 away from the left wing valve 16, and the other second limit shaft 17 is fixedly connected to the middle of a side of the left wing valve 16 away from the right wing valve 14.

[0021] The controller 6 is electrically connected to the motor 7 and the weighing sensor 15 respectively by wires, and the controller 6 is convenient for receiving the weight data transmitted by the weighing sensor 15 to control the opening and closing of the right wing valve 14 and the left wing valve 16 according to the weight of the dust.

[0022] The top ends of the right wing valve 14 and the left wing valve 16 are in contact with the bottom end of the dust collecting box 4, and the ends of the right wing valve 14 and the left wing valve 16 away from the first limit shaft 10 are slidably connected to the inside of the supporting arc groove 11, and the right wing valve 14 and the left wing valve 16 are supported by the first limit shaft 10 and the supporting arc groove 11 to prevent the right wing valve 14 and the left wing valve 16 from deformation.

[0025] Working principle: When the bag filter 2 is used for dust removal, the dust separated by the bag filter 2 falls into the dust collection box 4 under the action of gravity and accumulates. The accumulated dust is located at the top of the right wing valve 14 and the left wing valve 16. The weighing sensor 15 transmits the weight data to the controller 6 in real time. The controller 6 responds according to the preset program. When the controller 6 receives the weight information transmitted by one of the weighing sensors 15 and reaches the threshold and continues to increase, the controller 6 controls the motor 7 to start, and the driving end of the motor 7 drives the threaded rod 8 to rotate. Since the threaded sleeve 12 and the threaded rod 8 are threadedly connected, the rotation of the threaded rod 8 drives the threaded sleeve 12 to move in the direction close to the motor 7. The movement of the threaded sleeve 12 drives the pull rod 13 to rotate at one end close to the threaded sleeve 12 and drives the pull rod 13 to move. The movement of the pull rod 13 drives the second limit shaft 17 to move. The movement of 17 drives the right wing valve 14 and the left wing valve 16 to rotate around the first limit axis 10, and the ends of the right wing valve 14 and the left wing valve 16 close to the supporting arc groove 11 slide out of the supporting arc groove 11 respectively, until the right wing valve 14 and the left wing valve 16 rotate to a predetermined angle, at this time, the valve opens the right wing valve 14 and the left wing valve 16 away from the dust discharge port at the bottom of the dust collecting box 4, and the dust inside the dust collecting box 4 loses support and falls downward under the action of gravity. When the dust inside the dust collecting box 4 is completely discharged, the controller 6 controls the motor 7 to rotate in the opposite direction, thereby driving the threaded sleeve 12 to move close to the fixed plate 9, and the movement of the threaded sleeve 12 pushes the pull rod 13 to move, thereby pushing the right wing valve 14 and the left wing valve 16 to rotate, and the ends of the right wing valve 14 and the left wing valve 16 close to the supporting arc groove 11 slide into the inside of the supporting arc groove 11 and return to the initial position and the valve is closed.
