DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1 to 3. In the embodiment of the utility model, a pulse bag dust collector dust collecting device includes a dust collecting chamber 1. A pulse solenoid valve 2 is installed on the top outer wall of the dust collecting chamber 1. The pulse solenoid valve 2 is used to generate high-pressure air pressure to vibrate the collecting plate to make the dust fall. A discharge hopper 3 is installed at the bottom end of the dust collecting chamber 1 to provide a guide for the removal of dust. The bottom end of the discharge hopper 3 is threadedly connected with a collection box 4 for collecting dust. A transmission mechanism 5 is arranged in the inner cavity of the discharge hopper 3. The transmission mechanism 5 is used to block the bottom of the discharge hopper 3 when the collection box is replaced.

The transmission mechanism 5 includes a transmission unit and a blocking unit;

The blocking unit is used to block the inner cavity of the unloading ash hopper 3;

The transmission unit is used to provide power for the activities of the plugging unit;

The blocking unit includes a fixing plate 502, a partition plate 503, and a protrusion 504;

The fixed plate 502 is fixed to the inner cavity of the unloading end of the unloading ash hopper 3, and the fixed plate 502 is used to provide support for the rotation of the partition plate 503;

The partition plate 503 is rotatably connected to the outer wall of the fixed plate 502, and the partition plate 503 in the movable state is used to block the unloading end of the unloading ash hopper 3;

The protrusion 504 is fixed on the outer wall of the rotating shaft of the partition 503 and extends to the inner cavity of the fixed plate 502. The protrusion 504 is used to drive the partition 503 to rotate;

The transmission unit includes a stop rod 501, a movable rod 505, a spring 506, a stop block 507, and a docking rod 508;

The push rod 501 is fixed in the inner cavity of the collecting box 4 and is located at the center of the unloading ash hopper 3. The push rod 501 is used to give an upward thrust to the docking rod 508;

The movable rod 505 is vertically slidably installed in the inner cavity of the fixed plate 502, and the movable rod 505 is used to drive the stop block 507 to move synchronously;

The two ends of the spring 506 are respectively clamped on the outer wall of the movable rod 505 and the inner cavity of the fixed plate 502, and the spring 506 is used to give the movable rod 505 a downward elastic force to squeeze;

The stopper 507 is fixed on the outer wall of the movable rod 505 and is located above the protrusion 504. The stopper 507 is used to give the protrusion 504 a downward thrust.

The docking rod 508 is fixed to the bottom end of the stop block 507 and extends to the outside of the fixed plate 502 . The docking rod 508 is used to drive the movable rod 505 to move.

In this embodiment: when the collection box 4 needs to be replaced, the collection box 4 is separated from the unloading ash hopper 3 by rotating the collection box 4. After the separation, the collection box 4 will synchronously drive the push rod 501 to move out, and the push rod 501 will no longer provide an upward extrusion force for the docking rod 508. Then the movable rod 505, the docking rod 508, and the push block 507 will all move downward under the elastic force of the spring 506. The push block 507 moving downward will contact the outer wall of the protrusion 504 in the oblique upward state, giving the protrusion 504 a downward extrusion force, causing the protrusion 504 to rotate ninety degrees. Then the partition 503 in the vertical state will also rotate with the rotation of the protrusion 504, causing the partition 503 in the vertical state to rotate to a straight state and fit the inner cavity of the unloading ash hopper 3 (it should be supplemented that the spring 506 is always in a compressed state, and the elastic force of the spring 506 is greater than the weight of the two partitions 503 and the dust distributed on the top of the partition 503);

When the pulse solenoid valve 2 continues to work and shakes off the dust, the dust will fall on the upper surface of the partition 503, blocking the discharge port of the discharge ash hopper 3. There is no need to stop working until the next collection box 4 is docked with the discharge ash hopper 3. The support rod 501 gives an upward thrust to the docking rod 508, so that the support block 507 no longer gives an extrusion pressure to the protrusion 504. Then the protrusion 504 will rotate to a vertical state under the action of gravity, and the dust falling on the upper surface of the partition 503 will also fall into the collection box 4 under the vibration force, further improving the work efficiency.

Please refer to Figures 1 to 3 in particular. The interior of the fixed plate 502 is formed with a movable groove for the movable rod 505, the stop block 507, and the docking rod 508 to move upward. The outer wall of the movable rod 505 is in a "earth" shape as a whole.

In this embodiment, the vertical range of the movable rod 505 can be limited by this structure, so that the maximum moving distance of the movable rod 505 will not drive the stop block 507 to cross the protrusion 504 .

Please refer to Figures 1 to 3 in particular. There are two partitions 503, which are symmetrically distributed on the outer wall of the fixed plate 502. When the partitions 503 are in contact with the inner cavity of the ash hopper 3, the protrusions 504 are inclined.

In this embodiment, this structure allows the protrusion 504 to remain in an inclined state as a whole when the partition 503 is in a vertical state, so as to be able to receive the squeezing force from the stop block 507 moving downward.

What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
