Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea drying box. Background Technology

[0002] Drying is the final step in tea processing. Its purpose is to evaporate the moisture from the tea leaves, bringing them to a certain degree of dryness to ensure their quality and taste. Drying also kills bacteria and microorganisms in the tea leaves, preventing spoilage.

[0003] A Chinese patent, CN221764117U, describes a tea drying machine. It features a feeding mechanism at the inlet, comprising a hopper and a screw feeder. Tea leaves are placed in the hopper, and the screw feeder spreads them evenly onto the upper conveyor belt. Therefore, this invention eliminates the need to pre-place the tea leaves on a tray or manually spread them out. The tea leaves automatically flip as they fall from the upper conveyor belt to the lower conveyor belt. A humidification box maintains humidity within the machine, improving the drying effect. However, during operation, uneven distribution occurs when the tea leaves are transported across multiple conveyors, resulting in uneven drying. This invention addresses these issues by providing a tea drying box. Utility Model Content

[0004] This utility model provides a tea drying box, including a box body, multiple conveyors and a feeding hopper. The multiple conveyors are arranged in layers from top to bottom in the box body, and adjacent two conveyors are staggered. The feeding hopper is connected to the top of the box body. The feature is that it also includes multiple rotating plates. The feeding hopper is provided with a uniform conveying component. The multiple rotating plates are respectively arranged above the conveyor belts of the multiple conveyors, and adjacent two rotating plates are arranged opposite each other. The front side of the box body is provided with a drive mechanism to drive the multiple rotating plates to rotate.

[0005] Preferably, the driving mechanism includes a driving frame, a worm, a rotating rod, and a worm wheel. The driving frame is connected to the front side of the housing.

[0021] like Figure 1-4 As shown, the present invention proposes a tea drying box, which includes a box body 1, multiple conveyors 2 and a feeding hopper 3. The multiple conveyors 2 are arranged in layers from top to bottom inside the box body 1, and adjacent two conveyors 2 are arranged in an alternating manner. The feeding hopper 3 is connected to the top of the box body 1 and also includes multiple rotating plates 5. The feeding hopper 3 is provided with a uniform conveying component 4. The multiple rotating plates 5 are respectively arranged above the conveyor belts of the multiple conveyors 2, and adjacent two rotating plates 5 are arranged opposite each other. The front side of the box body 1 is provided with a drive mechanism 6 for driving the multiple rotating plates 5 to rotate.

[0022] In this invention, multiple conveyors 2 are staggered, which allows tea leaves to flip over when they fall onto the next conveyor 2, thus accelerating the drying process. However, tea leaves falling from above are relatively unstable and may accumulate excessively in certain areas. By setting up a uniform conveying component 4 to convey the same volume of tea leaves each time, and by using a drive mechanism 6 to drive two adjacent rotating plates 5 to rotate relative to each other, the bottom of the rotating plate 5 is kept at the same height as the conveyor 2. At the same time, the thickness of the tea leaves changes according to the different types of tea leaves. The bottom of the rotating plate 5 intercepts any excessively tall tea leaves, making the tea leaves passing over the rotating plate 5 more uniform and facilitating drying.

[0023] In an optional embodiment, the drive mechanism 6 includes a drive frame 61, a worm gear 62, a rotating rod 63, and a worm wheel 64. The drive frame 61 is connected to the front side of the housing 1. The worm gear 62 is rotatably connected to the bottom wall of the drive frame 61 and extends above it. One end of the rotating rod 63 is rotatably connected to the rear side wall of the housing 1, and the other end is rotatably connected to the front side wall of the drive frame 61. The worm wheel 64 is coaxially fixedly sleeved on the rotating rod 63 and meshes with the worm gear 62. The rotating plate 5 is coaxially fixedly sleeved on the rotating rod 63.

[0024] It should be noted that the drive mechanism 6 is provided in two sets, which respectively adjust the angle of multiple rotating plates 5 on the left and right sides. During adjustment, the worm gear 62 is turned to drive the worm wheel 64 to rotate, so that the rotating plates 5 on the same side rotate simultaneously.

[0025] In an optional embodiment, the uniform conveying assembly 4 includes a motor 41, a rotating shaft 42, and a conveying roller 43. The motor 41 is located on the rear side of the feed hopper 3. One end of the rotating shaft 42 is coaxially connected to the output shaft of the motor 41, and the other end is rotatably connected to the rear side wall of the feed hopper 3. The conveying roller 43 is coaxially fixedly sleeved on the rotating shaft 42, and multiple guide grooves are provided on the conveying roller 43.

[0026] It should be noted that during feeding, the starting motor 41 drives the rotating shaft 42 to rotate the conveyor roller 43. Since multiple guide troughs of the same size are provided, the amount of tea leaves transported to the conveyor 2 each time is equal.

[0027] In an optional embodiment, the interior of the housing 1 is provided with a plurality of heating tubes 9 and is located behind a plurality of conveyors 2.

[0028] In an optional embodiment, a protective net is provided on the rear side of the housing 1, and a fan 8 is provided on the rear side of the housing 1.

[0029] In an optional embodiment, the interior of the housing 1 is provided with a guide hopper 7, which extends to its left side.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
