[0015] Example 1, as Figures 1 to 4As shown, the present invention proposes a tea leaf washing device, including a separation box 1, a first screening mechanism 2, a second screening mechanism 3, and a washing mechanism; the upper end of one side wall and the lower end of the opposite side wall of the separation box 1 are provided with clearance openings 102, and the top inlet of the separation box 1 is integrally formed with a guide hopper A101 to facilitate the smooth guidance of the tea leaves to the first screening mechanism 2 for screening; a waste frame 103 is slidably connected to the bottom of the separation box 1; the first screening mechanism 2 is installed inside the upper part of the separation box 1 and includes a screening box 201, a screen 203, and a sealing plate 207; the screening box 201 is elastically connected to the separation box 1 along the height direction inside the separation box 1, and the screening box 201 is inclinedly distributed in the separation box 1, and the screening box 201 is also provided with a washing mechanism. 01 The discharge end extends through the corresponding clearance port 102 to the outside of the separation box 1. A vibrating element 204 is installed on the screening box 201. The vibrating element 204 is a vibrating motor. It can output a vibration force with a suitable amplitude to the screening box 201 through the controller. The separation box 1 has wiring holes corresponding to the vibrating element 204. This is common knowledge and will not be described in detail. The bottom end face of the screening box 201 and the part inside the separation box 1 has an opening. The screen 203 is fixedly connected to the opening. The sealing plate 207 is adjustable and slidably connected to the inner wall of the screening box 201 along the height direction of the screening box 201. The second screening mechanism 3 is installed inside the separation box 1. The second screening mechanism 3 is located below the first screening mechanism 2 and above the waste frame 103. The second screening mechanism 3 has the same structure as the first screening mechanism 2. The two sets of screening boxes 201 in the second screening mechanism 3 and the first screening mechanism 2 are tilted in opposite directions relative to the separation box 1. The mesh size of the screen 203 in the second screening mechanism 3 is smaller than that of the screen 203 in the first screening mechanism 2. Two sets of cleaning mechanisms are provided, which are installed on the left and right sides of the separation box 1 and are adapted to the corresponding relief openings 102. The cleaning mechanism includes a cleaning box 4, a tea frame 402, an upper diversion pipe 5, and a lower diversion pipe 501. The cleaning box 4 is connected to the side wall of the separation box 1. The top of the cleaning box 4 is integrally formed with a guide hopper B401, which facilitates the smooth introduction of fresh leaves after screening in the first screening mechanism 2 or the second screening mechanism 3 into the tea box. In frame 402, a sensor can be installed on the side wall of the guide hopper B401. When tea leaves are discharged into the tea frame 402, the detection information is transmitted to the controller. The controller then activates the external water supply mechanism to deliver spray water at a suitable pressure to the water inlet pipe 502. The tea frame 402 is driven by a servo motor installed on the side wall of the cleaning tank 4 to rotate back and forth with the inner wall of the cleaning tank 4. Two sets of rotating shafts are symmetrically connected to the cleaning tank 4. The rotating shafts are rotatably connected to the cleaning tank 4 through bearings. The bearings are equipped with sealing rings. The servo motor integrates a motor, a gearbox, and a high-precision position sensor. The controller can drive the servo motor to rotate the tea frame 402 to a suitable angle. The upper diversion pipe 5 is installed inside the upper part of the cleaning tank 4 through a connector.The lower diversion pipe 501 is installed inside the cleaning tank 4 via a connector. An inlet pipe 502 connects the lower diversion pipe 501 and the upper diversion pipe 5, with the inlet end of the inlet pipe 502 extending to the outside of the cleaning tank 4. Multiple sets of rotating nozzles are evenly connected to the upper diversion pipe 5 and the lower diversion pipe 501.

[0016] Furthermore, the side wall of the screening box 201 is uniformly and integrally formed with multiple sets of ear seats 202, and multiple sets of uprights are installed on the inner wall of the separation box 1. The uprights are slidably inserted into the corresponding ear seats 202, and springs are installed at the top and bottom of the ear seats 202. The springs are movably sleeved on the outside of the uprights, and the other end of the springs is connected to the end of the uprights.

[0017] Furthermore, the size of the screening box 201 in the first screening mechanism 2 is smaller than that in the second screening mechanism 3, and the area of ​​the screen 203 in the first screening mechanism 2 is smaller than that in the second screening mechanism 3. The tea leaves after screening in the first screening mechanism 2 fall smoothly into the second screening mechanism 3, avoiding leakage from the gap between the screening box 201 and the separation box 1. Through the step-by-step screening by the two sets of screens 203, the larger and smaller tea leaves can be separated, which is convenient for subsequent targeted cleaning.

[0018] Furthermore, a lifting component 205 is installed at the top of the screening box 201. The lifting component 205 is a hydraulic rod equipped with a displacement sensor to facilitate real-time monitoring of the lifting distance of the driving sealing plate 207. A connecting frame 206 is installed at the output end of the lifting component 205. The top of the sealing plate 207 extends to the outside of the top of the screening box 201 and connects with the connecting frame 206. The side wall and bottom of the sealing plate 207 abut against the inner side wall and bottom of the screening box 201, respectively. Rubber pads are provided at the abutting ends of the sealing plate 207. By starting the lifting component 205 through the controller, the sealing plate 207 slides upward along the inner wall of the screening box 201, which can open the discharge channel of the screening box 201. With the vibration of the screening box 201, the tea leaves after internal screening are easily output along the discharge end to the corresponding washing box 4. The size of the discharge channel between the sealing plate 207 and the screening box 201 can also be adjusted by the displacement distance of the output end of the lifting component 205, thereby adjusting the discharge speed of the tea leaves.

[0019] Furthermore, the rotation angle range of the tea frame 402 relative to the washing box 4 is set within ±45° to prevent the fresh leaves from scattering due to excessive rotation angle of the tea frame 402.

[0020] In this embodiment, the controller activates the first screening mechanism 2 and the second screening mechanism 3 to vibrate at an appropriate amplitude. Fresh tea leaves are poured from the feed hopper A101 into the separation box 1. The tea leaves are vibrated and screened step by step in the screening boxes 201 of the first screening mechanism 2 and the second screening mechanism 3, so that tea leaves of different sizes remain in the upper and lower screening boxes 201 respectively, while smaller impurities fall into the waste frame 103 at the bottom. After screening, the controller activates the corresponding lifting component 205 to drive the sealing plate 207 to slide upward along the inner wall of the screening box 201 to an appropriate height. With the continuous vibration of the screening box 201, the tea leaves are moved along... The tea leaves are discharged into the corresponding washing tank 4 through the screening box 201, which can then screen the tea leaves for subsequent targeted cleaning. The tea leaves fall into the tea frame 402 after entering the washing tank 4. The controller starts the external water supply mechanism to deliver water of appropriate pressure to the water inlet pipe 502, and then distributes it to the upper distribution pipe 5 and the lower distribution pipe 501. Finally, it is sprayed out along multiple sets of rotating nozzles. The controller starts the servo motor to drive the tea frame 402 to rotate back and forth, which can turn the tea leaves in the tea frame 402. At the same time, the spraying of multiple sets of rotating nozzles further improves the cleaning efficiency. The cleaning wastewater is discharged and recycled through the drain valve at the bottom of the washing tank 4.

[0021] Example 2, as Figure 2 and Figure 3 As shown, the tea leaf washing device proposed in this utility model, compared with Embodiment 1, has the output end of the rotating nozzle on the upper diversion pipe 5 inclined downward relative to the tea frame 402, and the output end of the rotating nozzle on the lower diversion pipe 501 inclined upward relative to the tea frame 402.

[0022] In this embodiment, multiple sets of rotating nozzles spray water onto the tea leaves in the tea leaf frame 402 at various angles, forming an all-around water flow that can thoroughly wash away dust and impurities in the tea leaves, further improving cleaning efficiency.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
