[0027] The housing 1 serves as an external protection structure. At both the left and right ends of the housing 1, there are fixedly connected cover plates 2. Inside the housing 1, there are a second screening barrel 4 and a first screening barrel 5 that screen tea leaves by rotation. At the left ends of the second screening barrel 4 and the first screening barrel 5, there is a fixedly connected rotating ring 3. The left side of the rotating ring 3 is rotatably connected to the inner side of the left end cover plate 2. At the upper outer sides of the second screening barrel 4 and the first screening barrel 5, there are brush plates 12. The right ends of the brush plates 12 are respectively fixedly connected to the left side of the right end cover plate 2.

[0028] The provided second screening barrel 4 and first screening barrel 5 can rotate inside the housing 1 and the cover plates 2 through the rotating ring 3. The rotating second screening barrel 4 and first screening barrel 5 achieve the classification screening of tea leaves. The tea leaves first enter the inside of the first screening barrel 5. The first screening barrel 5 rotates to conduct a preliminary screening of the tea leaves. The smaller tea leaves and tea powder pass through the first screening barrel 5 and fall onto the second screening barrel 4. Through the rotation of the second screening barrel 4, a secondary screening is carried out. The tea powder passes through the second screening barrel 4 and is discharged; the provided brush plates 12 can clean the second screening barrel 4 and the first screening barrel 5 when they rotate, preventing tea leaves from getting stuck in the screening holes.

On the upper side of the support plate 14, there is a fixedly connected motor 15. The driving end of the motor 15 is fixedly connected with a gear 16. On the outer wall of the left end of the second screening barrel 4, there is a fixedly connected toothed ring 13. The outer side of the toothed ring 13 is meshed with the outer side of the gear 16, which is used to drive the second screening barrel 4 and the first screening barrel 5 to rotate. In the middle of the left side of the left end cover plate 2, there is a fixedly connected feed pipe 9. In the middle of the right side of the right end cover plate 2, there is a fixedly connected discharge pipe 7. At the lower end of the right end cover plate 2, there is a discharge opening 8. At the lower side of the housing 1, there is a slag discharge port 6. At the outside of the housing 1 corresponding to the slag discharge port 6, there is a fixedly connected diversion plate 17.

[0030] Put the tea leaves into the feed pipe 9 and enter the inside of the first screening barrel 5. Start the motor 15 to drive the gear 16 to rotate. Through the cooperation of the rotating gear 16 and the toothed ring 13, drive the second screening barrel 4 and the first screening barrel 5 to rotate. The first screening barrel 5 conducts a preliminary screening of the tea leaves. The larger tea leaves remain inside the first screening barrel 5 and move to the right, and are discharged and collected through the discharge pipe 7. The smaller tea leaves and tea powder pass through the first screening barrel 5 and fall inside the second screening barrel 4. Through the rotation of the second screening barrel 4 for screening, the powder passes through the second screening barrel 4 and is discharged through the slag discharge port 6 and the diversion plate 17. The smaller tea leaves remain inside the second screening barrel 4 and move to the right, and are discharged through the discharge opening 8. Tea leaves can be continuously put in, classified and screened, and the screened tea leaves can be discharged in time, effectively improving the efficiency of tea leaf screening.

[0031] Refer to Figure 1 andFigure 3 , the bottom plate 10 serving as a load-bearing structure has support legs 11 fixedly connected to the four corners of its lower side for supporting the device. The right end of the bottom plate 10 is rotatably connected to the lower side of the right end cover plate 2. Chutes 18 are provided on the upper sides of the front and rear ends of the bottom plate 10. Sliders 19 are slidably connected to the inner sides of the chutes 18. Push plates 20 are rotatably connected to the upper ends of the sliders 19. Connecting blocks 21 are rotatably connected to the left ends of the push plates 20.

The driving ends of the electric push rods 23 are respectively fixedly connected to the middles of the sliders 19 for adjusting the inclination angle of the housing 1. A cushion plate 24 is fixedly connected to the middle of the upper side of the left end of the bottom plate 10. The upper end of the cushion plate 24 is in close fit with the outer wall of the cover plate 2.

[0032] The provided electric push rod 23 drives the slider 19 and the push plate 20 to move, thereby pushing the housing 1 to rotate and adjust the angle, facilitating the movement of the tea leaves to the right for convenient discharge, and the corresponding angle can be adjusted according to requirements to adjust the discharge speed of the tea leaves.

[0033] Working principle: Start the electric push rod 23 to drive the slider 19 to move leftward, thereby driving the push plate 20 to push the housing 1 to rotate and adjust the angle of the housing 1, facilitating the entry of tea leaves and their movement to the right. The tea leaves are put into the feeding pipe 9 and enter the inner side of the first screening barrel 5. Start the motor 15 to drive the gear 16 to rotate. The rotating gear 16 cooperates with the toothed ring 13 to drive the second screening barrel 4 and the first screening barrel 5 to rotate. The first screening barrel 5 conducts preliminary screening on the tea leaves. The larger tea leaves remain inside the first screening barrel 5 and move to the right, being discharged and collected through the discharge pipe 7.
