[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-3This utility model provides a technical solution: a withering device for fresh green tea leaves, including a withering box 1. The withering box 1 has an air inlet and an air outlet on both sides. When the tea leaves are withered, hot air is introduced into the withering box 1 through the air inlet to wither the tea leaves. The hot air is discharged through the air outlet to achieve circulation. The side wall of the withering box 1 is also hinged with a box door 2. The interior of the withering box 1 is provided with a placement box 3 and a fixing rod 4. The side wall of the placement box 3 is symmetrically provided with fixing ears 5. The fixing ears 5 are slidably sleeved on the fixing rod 4, and a first spring 12 is sleeved on the surface of the fixing rod 4 at the lower end of the fixing ears 5. This allows the placement box 3 to be suspended within the withering box 1, facilitating subsequent vibration operations on the placement box. Furthermore, the placement box 3 is constructed entirely of perforated metal plate, ensuring proper hot air circulation during the withering process. The placement box 3 is equipped with a placement rack 6, and the withering box 1 is also equipped with a driving component that drives the placement box 3 to vibrate. The driving component includes a fixed plate 7 fixedly installed on the top of the withering box 1 and a pressure rod 8 installed on the top of the placement box 3. A servo motor 9 is fixedly installed on the side wall of the fixed plate 7. A rotating rod 10 is fixedly connected to the output shaft of the servo motor 9. A drive wheel 11 is sleeved on the surface of the rotating rod 10. The drive wheel 11 has an elliptical structure. In this way, when the withering process is carried out, the servo motor 9 is turned on. The servo motor 9 drives the drive wheel 11 to rotate through the rotating rod 10. During the rotation of the drive wheel 11, it will intermittently push the pressure rod 8, thereby using the pressure rod 8 to push the placement box 3, causing the placement box 3 to vibrate up and down, which in turn causes the tea leaves on the placement rack 6 to vibrate, thereby improving the withering efficiency. Multiple sets of support plates 13 are fixedly installed on the inner wall of the placement box 3. Each set of support plates 13 has two sets, upper and lower, with the gap matching the height of the placement rack 6. A second spring 14 is also fixedly installed on the inner side wall of the placement box 3. The height of the second spring 14 matches the height of the placement rack 6. A handle 15 is fixedly installed on the outer side wall of the placement rack 6. The handle 15 has a semi-circular cross-section. The side wall of the box door 2 is also provided with a protrusion 16 that cooperates with the handle 15. The protrusion 16 has an isosceles trapezoidal cross-section. Through the second spring 14, the handle 15, and the cooperating protrusion 16, during the up-and-down vibration of the placement box 3, the protrusion 16 squeezes the handle 15, causing the multiple sets of placement racks 6 to swing horizontally. This assists the pressure rod 8, allowing the tea leaves to be fully tumbled and dispersed, facilitating the full withering of the tea leaves.

[0014] Working principle: In use, tea leaves are laid on the placement rack 6, and then the placement rack 6 is pushed into the placement box 3. The servo motor 9 is then started, and hot air is introduced into the withering box 1. The hot air withers the tea leaves. The servo motor 9 drives the drive wheel 11 to rotate through the rotating rod 10. During the rotation of the drive wheel 11, it intermittently pushes the pressure rod 8, which in turn pushes the placement box 3, causing the placement box 3 to vibrate up and down. This causes the tea leaves on the placement rack 6 to vibrate, improving the withering efficiency. Through the second spring 14, the handle 15, and the cooperating protrusion 16, during the up and down vibration of the placement box 3, the protrusion 16 squeezes the handle 15, causing multiple sets of placement racks 6 to swing horizontally. This assists the pressure rod 8, allowing the tea leaves to tumble and disperse fully, facilitating thorough withering.

[0015] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
