[0034] The main support seat 1 is connected to the bottom center of the workbench 2;

[0035] There are a plurality of hanging ears 5, which are installed on the outer peripheral surface of the workbench 2 and are evenly distributed along the central axis of the workbench 2 in a circumferential manner;

[0037] The first power drive assembly includes a rotating rod 6, a connecting rod 7, a connecting rod b and a driving device a;

[0038] The driving device a, the hanging ear 5, the rotating rod 6 and the connecting rod 7 correspond to each other one by one.

[0042] Embodiment 2

[0043] like Figure 1-3 As shown, the tea fermentation device proposed by the utility model, compared with the first embodiment, this embodiment further specifically discloses the specific structure of the second driving component and the rolling component.

[0044] In this embodiment, the second power drive assembly includes a mounting portion b10, a driving gear 11, a driven gear 12 and a driving device b14;

[0045] The driving gear 11 is rotatably connected to the mounting portion b10 through the rotating shaft a, and is also connected to the driving device b14; the driving device b14 is connected to the mounting portion b10; the rotating shaft a is connected to a rolling assembly 9;

[0046] The mounting part b10 is connected to the mounting part a8, and an inner gear ring is arranged in the mounting part b10; the inner side of the mounting part a8 is provided with but not limited to an inner thread, and the outer peripheral surface of the mounting part b10 is provided with but not limited to an outer thread, and the mounting part a8 and the mounting part b10 are detachably connected;

[0047] There are multiple driven gears 12, and the multiple driven gears 12 are all located between the driving gear 11 and the inner gear ring. The multiple driven gears 12 are meshed and connected to the driving gear 11 and the inner gear ring. The multiple driven gears 12 are evenly distributed in a circle with the central axis of the driving gear 11 as the center; when the driving gear 11 rotates, the speed of the driving gear 11 is slow and the diameter of the driving gear 11 is larger than the diameter of the driven gear 12. Therefore, when the driving gear 11 rotates, the rotation speed of the driven gear 12 is greater than the rotation speed of the driving gear 11, so that the scraped tea leaves are slightly scraped at a low speed and centrifuged to the high-speed position of the outer surrounding for scraping, so that the tea juice in the tea leaves can be efficiently dispersed and the fermentation rate is accelerated. The way in which the remaining rolling components 9 perform planetary motion is that they rotate themselves while following the driven gear 12 in the circular motion around the driving gear 11. The speed value during the rotation is higher than the speed value of the rolling component installed on the central driving gear 11.

[0048] Each rolling assembly 9 includes a rolling portion 13, and the rolling portion 13 includes a connecting portion and a scraping portion. The connecting portion is detachably connected to the driving gear 11 or the driven gear 12. The central through hole of each driven gear 12 is provided with an internal thread. The connecting portion of each rolling assembly 9 is provided with an external thread. The connecting portion on the rolling assembly 9 is threadedly connected to the driven gear. The size of the through hole and the internal thread on the driving gear 12 is consistent with the size of the through hole and the internal thread on the driven gear 12.

[0049] A plurality of scraping parts are provided, and the plurality of scraping parts are connected to the connecting part.

[0050] The projection of the scraping part is L-shaped, and the vertical ends of the multiple scraping parts are connected to the connecting part and are evenly distributed in a circle along the central axis of the connecting part. The scraping part can be used but not limited to bamboo. The bamboo scraping part can reduce the damage to the structure of the tea leaves themselves, and at the same time can efficiently open the skin of the surface of the tea leaves to extract the tea juice in the tea leaves, thereby promoting the fermentation process of the tea leaves.

[0051] In summary, in the utility model, the tea leaves are first placed in the rolling groove on the workbench 2. At this time, the three connecting rods 7 rotate synchronously under the synchronous drive of the three hidden motors, and drive the connecting rods 7 installed on the outside of the mounting part a8 to perform uniform circular motion, thereby driving the mounting part a8 to perform uniform circular motion along the central axis of the mounting part a8 above the workbench 2. When the mounting part a8 performs uniform circular motion, the driving device b14 is turned on, and the driving device b14 drives the active gear 11 and drives multiple driven gears 12 to perform planetary rotation, and drives multiple strip brushes 13 to rotate. When there are tea leaves on the workbench 2, the tea leaves can be effectively scraped. When the workbench 2 needs to be cleaned, the workbench can also be cleaned by self-rotation. The tea leaves on the workbench 2 can be stably turned over and scraped, ensuring effective and full contact with the tea leaves on the workbench 2, thereby achieving better fermentation effect.

[0052] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
