[0018] A dual-axis motor 6 is provided in the exhaust pipe 3, and an incomplete gear 15 is provided at one end of the dual-axis motor 6. A support plate 10 is provided in the exhaust pipe 3, and two sliding sleeves 13 are provided on the side of the support plate 10. By providing the sliding sleeve 13, the sliding sleeve 13 supports and limits the gear rod 14, so that the gear rod 14 can slide smoothly in the sliding sleeve 13. The gear rod 14 is slidably connected in the sliding sleeve 13, and a stopper 18 is provided on the front of the gear rod 14. A spring 17 is provided on the side of the gear rod 14. By providing the spring 17, under the elastic action of the spring 17, the knocking rod 16 can be quickly reset. One end of the spring 17 is connected to the sliding sleeve 13, and the other end of the spring 17 is connected to the stopper 18.

[0019] A knocking rod 16 is provided on the front of the block 18, and a connecting rod 7 is overlapped on the front of the knocking rod 16. A filter screen plate 8 is provided in the exhaust pipe 3. By setting the filter screen plate 8, the filter screen plate 8 can filter and block the debris dried by hot air. The connecting rod 7 is connected to the filter screen plate 8, and a rotating rod 9 is overlapped on the side of the filter screen plate 8. A movable rod 12 is provided on the side of the rotating rod 9. By setting the movable rod 12 and the rotating rod 9, the movable rod 12 supports and limits the rotating rod 9, so that the rotating rod 9 rotates smoothly. The other end of the movable rod 12 is connected to the dual-axis motor 6, and a positioning bearing 11 is provided on the side of the movable rod 12. The positioning bearing 11 is arranged on the side of the filter screen plate 8, and a box door 5 is provided on the front of the drying box 1.

[0020] The working principle of the utility model is:

[0021] When it is necessary to dry the black tea, firstly, the box door 5 is opened and the black tea to be dried is placed in the drying box 1, and then the box door 5 is closed again and the hot air box 2 and the exhaust pipe 3 are controlled to work, so that the hot air dries the black tea. At this time, the exhaust fan in the exhaust pipe 3 transports the filtered hot air to the drying box 1 again, so as to ensure the circulation drying of the black tea by the hot air.

[0022] When it is necessary to clean and collect the debris, firstly, the dual-axis motor 6 is controlled to work, so that the dual-axis motor 6 drives the movable rod 12 and the rotating rod 9 to rotate, and the debris on the surface of the filter screen plate 8 is scraped off and cleaned during the rotation of the rotating rod 9. At this time, the dual-axis motor 6 drives the incomplete gear 15 to rotate, so that when the incomplete gear 15 is in meshing contact with the gear rod 14, the gear rod 14 and the knocking rod 16 are separated from the connecting rod 7, and the spring 17 is compressed;

[0023] When the incomplete gear 15 is separated from the gear rod 14, in order to restore its own shape, the spring 17 drives the block 18 and the knocking rod 16 to quickly reset, so that the knocking rod 16 knocks and rotates the connecting rod 7. As the knocking vibration is transmitted to the rotating rod 9, the debris on the surface of the rotating rod 9 can be shaken off, so that the debris falls into the collection frame 4, and finally the collection frame 4 is pulled out of the exhaust pipe 3, thereby successfully completing the cleaning and collection of the debris.
