Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea air separation technology, specifically to a tea air separator with precise airflow adjustment and sorting device. Background Technology
[0002] Tea winnowing is a crucial step in tea processing. It utilizes wind power to separate light and heavy substances in tea leaves, distinguishing whole tea leaves from broken leaves, yellow leaves, and impurities. By adjusting the airflow, heavier, high-quality tea leaves (the "core tea") fall to the bottom, while lighter, inferior products or debris (such as tea stems and broken leaves) are blown further away, thus achieving tea grading and purification. A tea winnowing device, disclosed in CN222970336U, uses a fan to guide air through a guide plate, blowing air onto the tea leaves at the bottom of the inclined surface of the guide plate. Under the influence of airflow, tea leaves are separated according to their density and shape, resulting in different offsets and rising speeds. The leaves fall into different hoppers. The entire air separation device, through the combined action of the guide plate, claw roller, steps, and vibrating motor, ensures the uniform dispersion of tea leaves, which is beneficial to improving the tea leaf sorting effect. However, this air separation device cannot adjust the angle of the air separation gas, making it difficult to apply to tea leaves of different sizes and densities. This greatly reduces the efficiency of tea leaf sorting and has certain adverse effects on practical use. Therefore, improvements are needed. Utility Model Content
[0003] The purpose of this utility model is to provide a precise airflow adjustment and sorting device for tea air separators. The adjustment device enables the adjustment of the airflow angle, thereby adapting to tea leaves of different sizes and densities, thus improving the efficiency of tea sorting and bringing certain benefits to practical use, solving the problems mentioned in the background art above.

The blower frame 6 has several air inlet pipes 7 connected through its left side. An air intake fan 8 is fixedly installed inside the air inlet pipe 7. The blower frame 6 is rotatably connected to the rear side of the inner wall of the housing 1 via a bearing. An electric telescopic rod 9 is fixedly installed on the top of the housing 1 and near its left side. The bottom end of the electric telescopic rod 9 is inserted into the interior of the housing 1 and fixedly connected to a toothed plate 10. A gear 11 is movably engaged on the right side of the toothed plate 10. The gear 11 is fixedly connected to the front side of the blower frame 6 and rotatably connected to the front side of the inner wall of the housing 1.
[0015] Furthermore, the interior of the housing 2 is provided with a screen 12, which is inclined from right to left. A vibration motor 13 is fixedly installed on the front side of the screen 12. When the vibration motor is started, it can drive the screen 12 to vibrate, and the screen 12 can vibrate and screen the tea leaves.
[0016] Furthermore, a discharge trough is provided on the right side of the housing 2 near its bottom, and a guide plate 14 is fixedly installed on the right side of the discharge frame 3. The guide plate 14 is inclined from left to right and can guide the impurities screened from the tea leaves to the discharge trough.
[0017] Furthermore, a guide cylinder 15 is fixedly installed on the top of the guide plate 14, a spring 16 is fixedly installed on the bottom of the inner wall of the guide cylinder 15, a guide rod 17 is fixedly installed on the top of the spring 16, and the top of the guide rod 17 is fixedly connected to the bottom of the screen 12. The spring 16 can provide elastic support for the screen 12, thereby improving the vibration effect of the screen 12.
[0018] Example 2, please refer to Figures 1 to 5 The difference between this embodiment and embodiment 1 is as follows: a servo motor 18 is fixedly installed on the front side of the housing 2, and a rotating shaft 19 is fixedly installed on the output end of the servo motor 18. The other end of the rotating shaft 19 is rotatably connected to the rear side of the inner wall of the discharge frame 3 through a bearing. Several material-pushing plates 20 are fixedly installed on the outside of the rotating shaft 19. The material-pushing plates 20 can push the tea leaves inside the discharge frame 3, so that the tea leaves can fall evenly for air separation and prevent the tea leaves from clogging inside the discharge frame 3. A mounting base is fixedly installed on the left side of the inner wall of the housing 2 near its top. Several electric heating tubes 21 are fixedly installed on the right side of the mounting base.

[0019] Working Principle: When using this tea air separator with precise airflow adjustment and sorting device, the operator pours the tea leaves to be air-sorted onto the screen 12 through the feed frame. Then, the operator starts the vibration motor 13, which drives the screen 12 to vibrate, thus screening the tea leaves. The qualified tea leaves fall into the discharge frame 3. At this point, the operator starts the servo motor 18, which drives the rotating shaft 19 to rotate. The rotating shaft 19 then drives the material feeding plate 20 to rotate, which evenly distributes the tea leaves inside the discharge frame 3. The tea leaves are fed into the housing 1. At this time, the staff can start the air intake fan 8, which delivers air to the blowing frame 6. The air inside the blowing frame 6 can be discharged from the right side to air-sort the tea leaves. When it is necessary to air-sort different types of tea leaves, the staff can start the electric telescopic rod 9. The electric telescopic rod 9 can drive the toothed plate 10 to rise and fall. The toothed plate 10 can drive the gear 11 to rotate. The gear 11 can drive the blowing frame 6 to rotate, thereby realizing the adjustment of the airflow angle for air sorting, so as to adapt to tea leaves of different sizes and densities, and thus improve the efficiency of tea sorting.
