[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] Example

[0023] A tea hot air drying device, such as Figure 1-3As shown, it includes a frame 1, a drying barrel 2 fixed on the frame 1 by screws, a lifting mechanism 3 installed inside the frame 1, and a loading barrel 4 placed on the lifting mechanism 3 and rising through the lifting mechanism 3 to enter the drying barrel 2.

[0024] like Figure 4 As shown, the frame 1 includes a frame support leg 11, and a placement platform 12 welded to the upper end of the frame support leg 11 and hollowed out in the center. Specifically, the placement platform 12 hollowed out in the center can facilitate the loading barrel 4 to pass through and enter the drying barrel 2.

[0025] See also Figure 4 The lifting mechanism 3 includes a hydraulic cylinder 31 fixedly installed in the frame 1 by bolts, a support plate 32 fixedly installed on the output end of the hydraulic cylinder 31 by bolts, a guide column 33 welded under the support plate 32, and a guide cylinder 34 with one end sleeved on the guide column 33 and the other end welded and fixed to the frame 1. Specifically, the use of the guide column 33 and the guide cylinder 34 is more conducive to the smooth lifting and lowering of the hydraulic cylinder 31. The surface of the support plate 32 is fixed with a limit clamp 321 by a latch, and the limit clamp 321 can prevent the loading bucket 4 from sliding and deflecting during the lifting process.

[0026] See also Figure 4 The loading barrel 4 is a metal cylinder with mesh holes. Specifically, in actual use, the upright air duct 221, the lower air outlet plate 222 and the upper air outlet plate 223 in the hot air ejection mechanism 22 eject hot air simultaneously. At this time, the drying barrel body 23 is filled with flowing hot air, and the flowing hot air can enter the loading barrel 4 through the mesh holes to dry the tea leaves.

[0027] like Figure 5 As shown, the drying barrel 2 includes a base 21 which is fixed to the frame 1 by screws and is hollowed out in the center, a hot air ejection mechanism 22 mounted on the base 21, a drying barrel body 23 which is equipped with the hot air ejection mechanism 22 and is fixed to the base 21 by screws, a cover plate 24 fixed to the top of the drying barrel body 23 by screws, a driving motor 25 fixedly mounted on the cover plate 24, and a spiral shaft 26 which is mounted on the output end of the driving motor 25 and extends to the inside of the drying barrel body 23.

[0028] In this embodiment, the upper surface of the base 21 is provided with an annular groove 211 for placing the hot air ejection mechanism 22 , and a pipe hole 212 penetrating the base 21 is opened on the annular groove 211 .

[0029] In the present embodiment, the hot air ejection mechanism 22 includes a plurality of upright air ducts 221 with side holes, a lower air outlet plate 222 welded to the lower end of the upright air duct 221 and having an inclined hole on the inner side, and an upper air outlet plate 223 welded to the upper end of the upright air duct 221 and having a side hole on the inner side. Specifically, the hot air ejection mechanism 22 is placed on the base 21 through the lower air outlet plate 222 in cooperation with the annular groove 211, and then fixedly installed by a clamp.

[0030] In the present embodiment, an external air duct interface 2211 is extended from the lower end of one of the upright air ducts 221 in the hot air ejection mechanism 22. Specifically, the external air duct interface 2211 can pass through the pipe hole 212 and be connected to an external air duct, so that the hot air transported from the outside can be ejected through the hot air ejection mechanism 22 to perform hot air drying on the tea leaves placed in the loading barrel 4.

[0031] In the present embodiment, a plurality of exhaust ports 231 are welded on the upper end of the drying barrel body 23, which can discharge the hot air containing water vapor inside the drying barrel body 23. The outer side surface of the drying barrel body 23 is integrally formed with reinforcing ribs 232, and an insulating layer 233 is glued and fixed using the reinforcing ribs 232. Specifically, the insulating layer 233 is glued on the surface of the drying barrel body 23, which can prevent the drying barrel body 23 from dissipating heat too quickly during use, thereby affecting the drying efficiency of the tea leaves in the loading barrel 4.

[0032] It should be further explained that, during the hot air drying process of tea leaves, the upright air duct 221, the lower air outlet plate 222 and the upper air outlet plate 223 in the hot air ejection mechanism 22 eject hot air simultaneously. At this time, the drying barrel 23 is filled with flowing hot air, and the flowing hot air can enter the loading barrel 4 through the mesh, and the driving motor 25 drives the spiral shaft 26 to rotate, so that the tea leaves in the loading barrel 4 are lifted and loosened, and then the flowing hot air is used to blow the tea leaves away, so that the hot air fully contacts the tea leaves, which can improve the drying efficiency and drying quality of the tea leaves.

[0033] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
