The first insert block 20 is inserted into the second connecting block 19 and is slidably connected to the second connecting block 19. The first insert block 20 has a T-shaped design.

[0033] During operation, the movable plate 16 moves, causing the insertion rod 18 to move along the inside of the second connecting block 19 until it is completely disengaged. Then, the outer main barrel 2 is pulled upward, causing the first insertion block 20 to move upward along the inside of the second connecting block 19 until it is completely disengaged, at which point the outer main barrel 2 is removed.

[0034] Furthermore, a discharge head 22 is welded to the bottom of the outer main barrel 2, a fixing block 23 is welded to the right side of the discharge head 22, a fixing seat 24 is welded to the bottom of the fixing block 23, a rotating block 25 is rotatably connected to the fixing seat 24, a baffle 26 is welded to the left side of the rotating block 25, and the inner wall of the rotating block 25 is circular.

[0039] During operation, the outer main barrel 2 rotates, and the outer main barrel 2 also rotates along the outer side of the support sleeve block 21.

[0040] Working principle: When sieving and discharging is required, the tea leaves are first placed into the sieving barrel 3. Then, the motor 11 on the left side of the fixed plate 10 is started, driving the first connecting block 12 to rotate. When the first connecting block 12 rotates, it drives the first insert block 20 and the outer main barrel 2 to rotate. The outer main barrel 2 drives the sieving barrel 3 to rotate, thereby causing the tea leaves to rotate and be sieved along the inside of the sieving barrel 3. The sieved tea leaves fall into the outer main barrel 2 through the sieving barrel 3. When the outer main barrel 2 rotates, it also rotates along the outside of the support sleeve 21. After sieving, the second insert block 28 is pulled outward, causing one end of the second insert block 28 to move outward along the inside of the baffle 26 until the second insert block 28 is completely disengaged from the discharge head 22. When the second insert block 28 is pulled, it drives... The return spring 27 is stretched and extended, and then the baffle 26 is rotated downward, causing the rotating block 25 to move downward along the fixed seat 24 at the bottom of the fixed block 23. Thus, the tea leaves that have been screened inside the outer main barrel 2 will be discharged along the discharge head 22. Then, the rotating handle 15 is rotated, causing the threaded rod 14 to rotate along the rotating sleeve block 13. When the threaded rod 14 rotates, it causes the moving plate 16 to move outward along the outside of the threaded rod 14. When the threaded rod 14 moves, it also moves outward along the outside of the guide rod 17. When the moving plate 16 moves, it causes the insert rod 18 to move along the inside of the second connecting block 19 until it is completely disengaged. Then, the outer main barrel 2 is pulled upward, causing the first insert block 20 to move upward along the inside of the second connecting block 19 until it is completely disengaged, at which point the outer main barrel 2 is removed.
