[0026] Specifically, such as Figure 1 and Figure 2 As shown, the pipe for conveying tea leaves is first connected to the connecting pipe 7. During the pressing process, the tea leaves enter the interior of the guide pipe 6 from the connecting pipe 7, and then fall into the pressing chamber 5 of the pressing seat 4 along the guide pipe 6. Subsequently, the first hydraulic cylinder 8 pushes the pressing plate 11 downward to press the tea leaves. After pressing into tea bricks, the adjusting table 3 rotates 90 degrees to move the pressing seat 4 away from the bottom of the guide pipe 6 to achieve material discharge.

After the adjusting table 3 is moved to a suitable angle, the self-locking structure realizes self-locking and fixation, ensuring that the pressing seat 4 is accurately moved below the guide tube 6.

[0031] Working principle: First, the pipe for conveying tea leaves is connected to the connecting pipe 7. During the pressing process, the tea leaves enter the interior of the guide pipe 6 through the connecting pipe 7, and then fall into the pressing chamber 5 of the pressing seat 4. Subsequently, the first hydraulic cylinder 8 pushes the pressing plate 11 downward to press the tea leaves. After pressing into tea bricks, the adjusting table 3 rotates 90 degrees to move the pressing seat 4 away from under the guide pipe 6 to achieve material discharge. At the same time as material discharge, the other two empty pressing seats 4 repeat the previous pressing operation. When moving, the drive motor 15 is started. The drive motor 15 drives the first gear 14 to rotate, which in turn drives the second gear 16 to rotate, thereby moving the adjusting table 3. After the adjusting table 3 moves to the appropriate angle, the self-locking structure achieves self-locking and fixation, ensuring that the pressing seat 4 moves accurately under the guide pipe 6. After pressing is completed, the pressing seat 4 is moved away from under the guide pipe 6. Then, the second hydraulic cylinder 10 pushes the ejector plate 9 upward. The ejector plate 9 pushes out the successfully pressed tea bricks from the pressing chamber 5 for easy handling by the staff. This structure realizes the function of convenient and rapid material discharge.
