Description

Technical Field

[0001] This utility model relates to the field of stem and leaf separation technology, specifically to a tea stem and leaf separation and screening device. Background Technology

[0002] Tea is a beverage made from the fresh leaves of plants in the Camellia genus of the Theaceae family through specific processing techniques. It has drinking, health, and cultural value. Botanically speaking, it is a perennial evergreen shrub or small tree with leathery leaves and serrated edges. The new buds and tender leaves are rich in active ingredients such as tea polyphenols, caffeine, and amino acids. It is suitable for growing in warm, humid, acidic soil. In actual tea processing, a sieving device is needed to separate the tea stems and leaves. In practice, it has the advantages of simple operation, stable structure, and good sieving effect.

[0003] Existing screening devices can only separate stems and leaves from one type of tea. Since there are many types of tea, the stems and leaves of various teas need to be separated sequentially to avoid mixing. This screening method reduces the working efficiency of the existing screening device. In addition, when using a barrel structure to collect tea leaves or stems and leaves, operators need to move and replace the barrel structure before the collection work can continue. This operation method reduces the practicality of the existing screening device. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a tea stem and leaf separation and screening device, which has the following beneficial effects:

[0015] (1) This utility model is equipped with a screening chamber. When the tea stem and leaf separation and screening device is actually used, multiple teas can be placed inside multiple filter barrels through multiple sets of shaft tubes. Then, the control panel is used to make the drive motor work. The output end of the drive motor can drive the main gear to rotate. Since the main gear meshes with multiple sets of driven gears, the rotating main gear can drive multiple sets of driven gears to rotate. The rotating multiple sets of driven gears can make multiple sets of filter barrels rotate through multiple sets of shaft tubes. Using centrifugal force, the tea stems in multiple teas can be screened. Multiple sets of movable covers can block the upper openings of multiple sets of shaft tubes. After the multiple tea stems are screened, the control panel is used to open and close multiple sets of electric slide valves. Multiple tea stems can be discharged through multiple sets of feed hoppers. Then, the control panel is used to extend multiple sets of electric telescopic rods. Multiple sets of bottom covers will be separated from multiple sets of filter barrels. At this time, multiple teas can be discharged through the feed hopper. Through the screening chamber, multiple teas can be screened at the same time, which improves the working efficiency of the tea stem and leaf separation and screening device.

[0016] (2) This utility model is equipped with a support plate, a first collection bucket and a second collection bucket. According to the above operation, the control panel is used to open and close multiple sets of electric slide valves, and multiple tea stems can be discharged through multiple sets of feed hoppers. Multiple tea stems will fall into the interior of multiple sets of first collection buckets. When multiple tea leaves need to be collected, the control panel is used to make the self-locking geared motor work. The output end of the self-locking geared motor can make the support plate rotate through the connecting shaft and the mounting screw. When multiple sets of second collection buckets are moved to the bottom of multiple sets of feed hoppers, the control panel is used to make the self-locking geared motor stop working. At this time, the control panel is used to extend the electric telescopic rod. At this time, multiple tea leaves will fall into the interior of multiple sets of second collection buckets. During this process, the operator can remove multiple sets of first collection buckets and clean the multiple tea stems inside. Repeating the above operation can continuously collect multiple tea stems and multiple tea leaves. The support plate, the first collection bucket and the second collection bucket can avoid moving the bucket structure and affecting the collection of tea leaves or stems, thus improving the practicality of the tea stem and leaf separation and screening device.

Through the screening chamber 2, multiple types of tea can be screened simultaneously, improving the working efficiency of the tea stem and leaf separation and screening device.

[0028] In one embodiment, a self-locking geared motor 20 is installed at the lower part of the mounting frame 19, and a connecting shaft 23 is installed at the output end of the self-locking geared motor 20 through a coupling. An installation screw 21 is fixedly installed at the upper end of the connecting shaft 23. The upper end of the installation screw 21 slides through the lower part of the support plate 9.

It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0032] In one embodiment, four sets of bases are mounted on the lower part of the mounting bracket 19.

[0033] Working principle:

[0034] In actual use of the tea stem and leaf separation and screening device, various types of tea can be placed inside multiple sets of filter barrels 7 through multiple sets of shaft tubes 4. Then, using the control panel, the drive motor 12 is activated. The output end of the drive motor 12 drives the main gear 17 to rotate. Since the main gear 17 meshes with multiple sets of driven gears 18, the rotating main gear 17 can drive the multiple sets of driven gears 18 to rotate. The rotating multiple sets of driven gears 18 can cause the multiple sets of filter barrels 7 to rotate through the multiple sets of shaft tubes 4. Utilizing centrifugal force, the tea stems in various types of tea can be separated. The sieving process involves multiple sets of movable covers 16 blocking the upper openings of multiple sets of shaft tubes 4. After the various tea stems have been sieved, the control panel is used to open and close multiple sets of electric slide valves 6, allowing the various tea stems to be discharged through multiple sets of feed hoppers 5. Then, the control panel is used to extend multiple sets of electric telescopic rods 13, causing multiple sets of bottom covers 15 to detach from multiple sets of filter screens 7. At this point, multiple tea leaves can be discharged through the feed hoppers 5. Through the screening chamber 2, multiple tea leaves can be sieved simultaneously, improving the working efficiency of the tea stem and leaf separation and sieving device. Simultaneously, according to the above... As described above, by using the control panel to open and close multiple sets of electric slide valves 6, various tea stems can be discharged through multiple sets of feed hoppers 5. The various tea stems will fall into the interiors of multiple sets of first collection buckets 10. When it is necessary to collect various tea leaves, the control panel is used to activate the self-locking geared motor 20. The output end of the self-locking geared motor 20 can rotate the support plate 9 through the connecting shaft 23 and the mounting screw 21. When the multiple sets of second collection buckets are moved to the bottom of the multiple sets of feed hoppers 5, the control panel is used to stop the self-locking geared motor 20. At this time, the control panel is used to extend the electric telescopic rod 13. At this time, various tea leaves will fall into the interiors of the multiple sets of second collection buckets. During this process, the operator can remove the multiple sets of first collection buckets 10 and clean the various tea stems inside. By repeating the above operation, the collection of various tea stems and various tea leaves can be continuously carried out. The support plate 9, the first collection bucket 10 and the second collection bucket can prevent the movement of the bucket structure from affecting the collection of tea leaves or stems, thus improving the practicality of the tea stem and leaf separation and screening device.
