The plurality of jet inner holes 20 are arranged along the length direction and the circumferential direction of the jet pipe 18, so as to improve the uniformity and drying efficiency of drying the tea.

[0023] Among them, the opening directions of the jet side holes 17 and the jet inner holes 20 are not limited. Preferably, the jet side holes 17 are opened perpendicular to the inner wall of the conical cylinder 13, and the jet inner holes 20 are opened along the radial direction of the jet pipe 18, so that the hot air blown out from the jet side holes 17 and the jet inner holes 20 can generate an interaction effect; at the same time, since the inclination directions of the jet side holes 17 and the jet inner holes 20 relative to the vertical line are the same, the component force of the blowing force on the tea and the dust is towards the direction of the air outlet pipe 15, so as to facilitate the discharge of the dust. Of course, both the jet side holes 17 and the jet inner holes 20 can be inclined to form a non-regular disturbed hot air.

[0024] Among them, the tea leaves fall on the air jet pipe 18 or the inner wall of the box body 11 after being turned over by the box body 11, so as to disperse the tea leaves, avoid uneven drying caused by caking of the tea leaves, and affect the output quality of the tea leaves.

A plurality of side holes 27 are arranged at intervals along the circumferential direction of the air guide pipe 19, and the air guide pipe 19 is rotationally sealed with the connecting cylinder 25.

[0030] The hot air blown out from the output end of the hot air blower 21 flows along the air guide pipe 19. A part of it flows into the air jet pipe 18 through the support pipe 24 and is ejected from the jet inner hole 20, and the other part flows into the annular groove 26 on the inner wall of the connecting cylinder 25 through the side holes 27 on the air guide pipe 19, and then flows into the bottom guide holes 23 and the side guide holes 22 in sequence, and finally is ejected from the jet side hole 17, so as to realize that while the connecting cylinder 25 rotates relative to the air guide pipe 19, the hot air blower 21 can simultaneously supply hot air to the jet side hole 17 and the jet inner hole 20.

[0031] Preferably, the air guide pipe 19 and the connecting cylinder 25 are rotationally connected through a bearing 28 and are sealed through a sealing ring 29. Bearings 28 and sealing rings 29 are provided on both sides of the annular groove 26.

[0032] Preferably, the connecting cylinder 25 and the air outlet pipe 15 are both rotationally connected to the support 10 through a support rod 30.

[0036] Preferably, a sealing plate 34 is arranged in the air outlet pipe 15. The sealing plate 34 is arranged between the hemispherical top cover 14 and the dust suction plate 31. A rotating shaft 35 is arranged along the radial direction of the sealing plate 34. The rotating shaft 35 is rotatably connected to the inner wall of the air outlet pipe 15. A torsion spring 36 is sleeved on the rotating shaft 35. The two ends of the torsion spring 36 are respectively connected to the air outlet pipe 15 and the sealing plate 34, so that the sealing plate 34 keeps the air outlet pipe 15 in a closed state.

[0037] Preferably, a gear ring 37 is arranged on the air outlet pipe 15, a motor 38 is arranged on the bracket 10, a gear 39 is arranged on the output shaft of the motor 38, and the gear 39 meshes with the gear ring 37.

[0038] Preferably, a material pipe 40 is arranged on the hemispherical top cover 14, and a plug 41 is arranged at the end of the material pipe 40.

[0039] The working principle of the present utility model is as follows:

[0040] The tea leaves to be dried are fed into the box body 11 through the material pipe 40. The motor 38 and the hot air blower 21 are started. The motor 38 drives the gear 39 and the gear ring 37 to rotate, causing the box body 11 to rotate. The hot air blown out from the output end of the hot air blower 21 flows along the air guide pipe 19. A part of the hot air flows into the air jet pipe 18 through the support pipe 24 and is ejected from the air jet inner hole 20. Another part of the hot air flows into the annular groove 26 on the inner wall of the connecting cylinder 25 through the side hole 27 on the air guide pipe 19, and then flows into the bottom guide hole 23 and the side guide hole 22 in sequence, and is finally ejected from the air jet side hole 17. Thus, while the connecting cylinder 25 and the air guide pipe 19 rotate relative to each other, the hot air blower 21 can simultaneously supply hot air to the air jet side hole 17 and the air jet inner hole 20. The rotation of the box body 11 causes the orientations of the air jet side hole 17 and the air jet inner hole 20 to change relatively, and the blown hot air generates an interaction of disturbance, so as to perform porous blowing drying on the tea leaves in the box body 11. At the same time, the box body 11 rotates to turn the tea leaves therein, further improving the drying effect. The dust attached to the tea leaves is blown off by the hot air and flows along the inclined surface of the inner wall of the conical cylinder 13 to the hemispherical top cover 14. The hot air causes the sealing plate 34 to rotate to open the inlet of the air outlet pipe 15. At the same time, the hot air also causes the dust to enter the air outlet pipe 15 and be adsorbed by the dust suction plate 31, preventing the dust from adhering to the inner wall of the box body 11 and being inconvenient to clean up.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
