The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] like Figure 1-3 An embodiment shown provides a tea withering device, comprising a cooling device 1, a vibrating device 2, a conveyor 3 and an elevator 4, wherein:

[0023] The discharge port of the cooling device 1 is connected to the feed port of the vibration device 2, and the discharge port of the cooling device 1 is higher than the feed port of the vibration device 2, the discharge port of the vibration device 2 is connected to the feed port of the conveyor 3, and the discharge port of the vibration device 2 is higher than the feed port of the conveyor 3, the discharge port of the conveyor 3 is higher than its feed port, the discharge port of the conveyor 3 is connected to the feed port of the elevator 4, the discharge port of the elevator 4 is connected to the feed port of the cooling device 1, and the discharge port of the elevator 4 is higher than the feed port of the cooling device 1;

[0024] The cooling device 1 includes a conveyor belt 11 and a driving mechanism 12. The driving mechanism 12 is configured to drive the conveyor belt 11 to move. A plurality of ventilation holes 13 are provided on the conveyor belt 11. A fan 14 is provided below the conveyor belt 11. By placing tea leaves on the conveyor belt 11 and then starting the fan 14 below the conveyor belt, the wind generated by the fan 14 passes through the ventilation holes 13, thereby drying the tea leaves on the conveyor belt 11. The dried tea leaves are then transported to the next device through the conveyor belt 11.

[0025] The working principle and use process of this embodiment:

[0026] When the utility model is in use, the tea leaves are first evenly arranged on the cooling device 1, and then the fan 14 of the cooling device 1 is started. The wind blown by the fan 14 passes through the ventilation holes 13 to cool the tea leaves. At the same time, the driving mechanism 12 is started to drive the conveyor belt 11 to move, thereby driving the tea leaves to move toward the discharge port of the cooling device 1. Since the discharge port of the cooling device 1 is higher than the feed port of the vibration device 2, when the tea leaves fall from the cooling device 1 into the vibration device 2, the tea leaves will have a first collision, and the tea leaves will fall into the vibration device 2 and be vibrated to produce a second collision. It should be noted that those skilled in the art can select the corresponding vibration device 2 according to needs. In this embodiment, the vibration device 2 can be The XFZD-1020 vibration machine of Xinxiang Pioneer Vibration Machinery Co., Ltd. is selected. After the vibration is completed, the tea leaves enter the feed port of the conveyor 3 from the discharge port of the vibration device 2. Since the discharge port of the vibration device 2 is higher than the feed port of the conveyor 3, a third collision occurs when the tea leaves fall from the vibration device 2 into the conveyor 3. After falling into the conveyor 3, the tea leaves are conveyed from the discharge port of the conveyor 3 into the feed port of the elevator 4. The discharge port of the elevator 4 is connected to the feed port of the cooling device 1. After being lifted by the elevator 4, the tea leaves fall into the cooling device 1, and the discharge port of the elevator 4 is higher than the feed port of the cooling device 1, so a fourth collision occurs. After the collision, the tea leaves complete a cycle.

[0027] Embodiment 2

[0028] This embodiment is developed on the basis of the above embodiment to solve the problem of how the conveyor belt 11 works. Specifically, Figure 1-3 As shown, the driving mechanism 12 includes a linear motor 121 and a reducer 122. The output shaft of the linear motor 121 is connected to the input shaft of the reducer 122 through a belt, and the output shaft of the reducer 122 drives the conveyor belt 11 to move. When the cooling device 1 needs to be started, the linear motor 121 is started, and the linear motor 121 rotates to drive the reducer 122 to rotate through the belt, and the reducer 122 rotates to drive the conveyor belt 11 to move.

[0029] Embodiment 3

[0030] This embodiment is developed on the basis of the above embodiment to solve the problem of how to cool tea leaves. Specifically, Figure 1-3 As shown, the diameter of the ventilation hole 13 is 1-2 cm. The ventilation hole 13 arranged in this way facilitates the passage of wind generated by the fan 14 while being smaller than the tea leaves, thereby preventing the tea leaves from falling through the ventilation hole 13.

[0031] Embodiment 4

[0032] This embodiment is developed on the basis of the above embodiment to solve the problem of tea leaves in the vibration device 2. Specifically, Figure 1-3 As shown, the vibration device 2 is arranged at an angle, and its feed port is higher than its discharge port. By the inclined arrangement, when the tea leaves vibrate on the vibration device 2, since its feed port is higher than its discharge port, the tea leaves will naturally move toward the discharge port under the action of gravity, and the tea leaves can be transported on the vibration device 2.

[0033] Embodiment 5

[0034] This embodiment is developed on the basis of the above embodiments to improve the aroma enhancement effect of tea leaves. Specifically, Figure 1-3 As shown, the discharge port of the cooling device 1 is 30-40 cm higher than the feed port of the vibration device 2, and the discharge port of the elevator 4 is 50-60 cm higher than the feed port of the cooling device 1. With this distance arrangement, the tea leaves can have the best collision effect while preventing them from falling out of the device.

[0035] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
