A first valve 51 is installed in the middle of the first rotating shaft 5. The first valve 51 is located in the upper cavity 13 and extends to the bottom of the ash collection hopper 21 to seal the channel between the collection hopper and the upper cavity 13. One end of the first rotating shaft 5 is connected to the first counterweight rod 53, and the other end of the first counterweight rod 53 is connected to the first transmission arm 52.

Dust enters the upper cavity 13. Under the action of the push plate 4, the dust falls onto the second valve 61 at the bottom of the filter hopper 2. The reduction motor 7 drives the swing arm 71 to apply torque to the second transmission arm 62, driving the second rotating shaft 6 to rotate, causing the second valve 61 to open, and the dust falls smoothly into the lower cavity 14.

[0046] In this embodiment, sealing rings 22 are provided at the connection between the bottom of the ash collection hopper 21 and the first valve 51, and at the connection between the bottom of the filter hopper 2 and the second valve 61. The sealing rings 22 can effectively prevent dust leakage.

[0047] The principle of this utility model is as follows: When dust enters the dust collection hopper 21 from the feed inlet 11, the vibration motor 3 starts to drive the swing arm 71. The swing arm 71 applies torque to the first transmission arm 52, causing the first rotating shaft 5 to rotate, thus opening the first valve 51. The dust on the first valve 51 is guided to the filter hopper 2 by the push plate 4. At the same time, the vibration motor 3 drives the vibration rod 31 to make the push plate 4 on the support 32 vibrate back and forth in the upper cavity 13. Under the action of the push plate 4, the dust falls onto the second valve 61 at the bottom of the filter hopper 2. The reduction motor 7 drives the swing arm 71 to apply torque to the second transmission arm 62, causing the second rotating shaft 6 to rotate, thus opening the second valve 61. The dust falls smoothly into the lower cavity 14, and the material is finally discharged from the discharge outlet 12, achieving efficient separation.
