Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea leaf turning device for use in tea sun-drying fields. Background Technology

[0002] Sun-drying is a crucial step in tea processing. Sun-drying involves spreading freshly picked tea leaves evenly on a drying ground and using natural light and air circulation to slowly evaporate the moisture in the tea leaves. This process also promotes changes in the internal chemical components of the tea leaves, such as enzymatic oxidation. Since the tea leaves need to be turned over constantly during sun-drying, a tea leaf turning device is used.

[0003] However, existing tea leaf turning devices still have certain defects. For example, they usually use a back-and-forth moving scraper to turn the tea leaves. Since the scraper usually moves in a straight line, some tea leaves may not be turned during the sun-drying process, thus affecting the sun-drying effect. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a tea leaf turning device for tea drying yards, which can adjust the position of the rubber scraper during the movement of the rubber scraper, so that the rubber scraper can turn the tea leaves more evenly, and avoid the situation where the tea leaves are not turned or are turned unevenly because the rubber scraper moves in a straight line.

The lower surface of the discharge bin 1 is fixedly connected to the support column 24. There are four support columns 24 arranged in a rectangular array. The drive motor 7 is electrically connected to an external power source.

[0029] The outer surface of the U-shaped frame 9 is provided with a limiting groove 12. A sliding rod 13 is fixedly connected to the inner surface of the limiting groove 12. A fixing plate 14 is slidably connected to the outer surface of the sliding rod 13. A rubber scraper 15 is fixedly connected to the lower surface of the fixing plate 14. A T-shaped seat 16 is fixedly connected to the upper surface of the fixing plate 14. A fixing post 17 is fixedly connected to the right surface of the T-shaped seat 16. A connecting rod 18 is rotatably connected to the outer surface of the fixing post 17. A connecting post 19 is rotatably connected to the inner surface of the connecting rod 18. A turntable 20 is fixedly connected to the left end of the connecting post 19. A rotating shaft 21 is fixedly connected to the inner surface of the filter screen 5. A low-speed motor 22 is fixedly connected to the left end of the rotating shaft 21. A connecting plate 23 is rotatably connected to the inner surface of the rotating shaft 21. The upper surface of the filter screen 5 is in contact with the rubber scraper 15. There are multiple rubber scrapers 15.

[0030] Working principle: In use, pour the tea leaves to be sun-dried onto the filter screen 5 inside the sun-drying frame 4 and spread them out. Then connect the external power supply and start the drive motor 7 and the low-speed motor 22 respectively. Under the action of the drive motor 7, the reciprocating screw 8 drives the U-shaped frame 9 to move back and forth along the guide rod 10, thereby turning the tea leaves over through the rubber scraper 15. During the turning process, because the small stones and other impurities contained in the tea leaves are much smaller than the tea leaves, these small stones and impurities will fall into the feed bin 1 through the holes on the filter screen 5, and then be acted upon by the inclined block 2. The material is quickly drawn into the material box 3 for collection, thereby reducing the labor intensity of the staff when cleaning impurities later. Under the action of the low-speed motor 22, the rotating shaft 21 drives the turntable 20 to rotate. Under the action of the connecting column 19, connecting rod 18, fixed column 17, T-shaped seat 16, and fixed plate 14, the rubber scraper 15 moves back and forth slowly along the slide bar 13. This continuously changes the position of the rubber scraper 15 during the leaf turning process, avoiding the situation where some tea leaves are not turned because the movement of the rubber scraper 15 is always in a straight line.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
