[0002] Black tea is a fully fermented tea, made from tea leaves through withering, rolling, fermentation, and drying. As an indispensable part of tea culture, during the production and processing of black tea, workers stir-fry the tea leaves. Stir-frying can destroy the enzyme activity in the tea leaves through high temperature to prevent the tea leaves from continuing to ferment, while also causing the moisture in the tea leaves to evaporate quickly to achieve the effect of enhancing aroma and removing bitterness, thereby reducing the bitterness and making the tea more mellow and sweet.
[0003] When using existing black tea processing stir-frying equipment, the outer surface of the stir-fryer blades will accumulate tea slurry and tea dust during long-term operation. If the stir-fryer is not cleaned in time, these residues may contaminate subsequent batches of tea. However, since the common stir-fryer is a structure in which the drive shaft and motor are integrated, this installation method makes it difficult to disassemble and assemble the stir-fryer, affecting the cleaning of the stir-frying blades, which is not conducive to the normal use of the stir-frying equipment.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-5As shown, a stir-frying device for black tea processing includes a base 1. Supports 4 are fixedly connected to the top of both sides of the base 1. Bearing seats 5 are fixedly installed at the top of the supports 4. A stir-frying pot 2 is located between the supports 4.

A first drive assembly 7 is provided below the supports 4 to provide rotational force to the rotating shaft 6. By setting the first drive assembly 7, the entire stir-frying pot 2 can be tilted towards the tea collection container with the rotating shaft 6 as the center, thus facilitating the unloading of the tea after stir-frying. An L-shaped plate 14 is positioned above the stir-frying pot 2. A first drive shaft 16 is provided at one end of the L-shaped plate 14. A second drive shaft 17 is provided below the first drive shaft 16. Stir-frying blades 18 are fixedly installed at the bottom end of the second drive shaft 17. The top end of the second drive shaft 17 is provided to facilitate the stirring of the stir-frying blades 18. The docking assembly 20 allows for easy disconnection between the first drive shaft 16 and the second drive shaft 17, facilitating the cleaning and maintenance of the stir-frying blades 18. Compared to common integrated structures, this reduces the difficulty of disassembling and assembling the stir-frying blades 18. The column 11, installed on top of the base 1, has a lifting assembly 21 on its outer side that adjusts the height of the stir-frying blades 18. This lifting assembly 21 allows the stir-frying blades 18 to leave the stir-frying pot 2 during tea feeding, preventing them from obstructing the tea feeding process. The top of the L-shaped plate 14 has a second drive assembly 19 that provides rotational force to the first drive shaft 16. This second drive assembly 19 enables the stir-frying blades 18, located at the bottom of the second drive shaft 17, to perform the tea stirring operation.
[0027] The first drive assembly 7 includes a first motor 71 disposed below the bracket 4. The first motor 71 is fixedly mounted on the top of the base 1. One end of a rotating shaft 6 and the output end of the first motor 71 are both fixedly connected to a transmission sprocket 72. The transmission sprockets 72 are connected to each other by a transmission chain. Figure 1 , Figure 2 As shown, the first motor 71 can drive the transmission sprocket 72 to rotate. The transmission sprocket 72, in turn, can drive the entire stir-fry pan 2 to tilt towards the tea collection container with the rotating shaft 6 as the center, which is conducive to the feeding process.
[0028] One of the brackets 4 has a protective cover 8 on its outer side. The protective cover 8 is located around the transmission sprocket 72, and one side of the protective cover 8 is connected to the bracket 4 by bolts. Figure 2 As shown, by setting up a protective cover 8, the exposed transmission sprocket 72 can be prevented from causing accidental injury to workers, thus improving safety performance.
[0029] The docking assembly 20 includes a disc seat 201 fixed to the top of the second drive shaft 17. A plug-in prism 202 is fixedly connected to the top of the disc seat 201. The first drive shaft 16 has a plug-in groove 203 corresponding to the plug-in prism 202 inside. The plug-in prism 202 is located inside the plug-in groove 203. A limiting disk 204 is fixedly connected to the outer side of the bottom end of the first drive shaft 16. The top of the inner cavity of the limiting disk 204 has at least three adjusting slots 205, and each adjusting slot 205 has a slidingly connected first adjusting slot. The second movable block 206 has a buckle 207 fixedly connected to its bottom. A corresponding slot 208 is provided on the outer side of the disc base 201, with the buckle 207 located inside the slot 208. A limiting plate 2011 is fixedly connected to the top of the second movable block 206. A fastening bolt 209 is provided inside the limiting plate 2011. An internal threaded groove 2010 is provided on the outer side of the insert prism 202. One end of the fastening bolt 209 passes through the limiting plate 2011 and connects to the internal threaded groove 2010. Figure 1 , Figure 2 and Figure 4 As shown, when it is necessary to disassemble and clean the stir-fry blade 18, the fastening bolts 209 on the outside of each limiting plate 2011 can be removed to disconnect the connection between the plug-in prism 202 and the plug-in groove 203. Then, the limiting plate 2011 can slide along the inner wall of the adjusting groove 205 via the second moving block 206, so that the bottom buckle 207 of the second moving block 206 moves away from the outer groove 208 of the disc seat 201. At this point, the restriction on the second drive shaft 17 is completely released. The staff can then pull the plug-in prism 202 out of the plug-in groove 203 and then carry out the cleaning and maintenance of the stir-fry blade 18. Compared with the common one-piece structure, this not only reduces the difficulty of disassembling and assembling the stir-fry blade 18, but also achieves dual positioning of the second drive shaft 17, making the stir-fry blade 18 more stable in operation.
[0030] The outer side of the wok 2 is provided with an insulation layer 3, and the interior of the insulation layer 3 is provided with a spiral heating wire 23. Multiple heat-conducting plates 13 are provided on the outer side of the spiral heating wire 23. The heat-conducting plates 13 are connected to the wok 2 and the insulation layer 3 respectively. The spiral heating wire 23 is fixedly installed inside the heat-conducting plates 13. A thermostat 22 is fixedly installed on one side of the wok 2. The spiral heating wire 23 is connected to the terminal of the thermostat 22 via wires. A heat insulation layer 12 is provided on the inner wall of the insulation layer 3. The heat insulation layer 12 is made of aerogel felt material. Figure 1 , Figure 3As shown, the tea leaves can be heated from the outside of the wok 2 by the thermostat 22 and the spiral heating wire 23. The heat distribution of the spiral heating wire 23 can be made more even by the heat-conducting plate 13. At the same time, the heat-conducting plate 13 can also act as a reinforcing rib, which improves the overall support strength of the wok 2. The heat insulation layer 12 slows down the heat exchange rate between the heat insulation layer 3 and the external environment, reducing resource waste.
[0031] A ring-shaped baffle 9 is fixedly connected to the top of the wok 2, and a discharge port 10 is provided on one side of the ring-shaped baffle 9, such as... Figure 1 , Figure 3 As shown, by setting the annular baffle 9, the chance of tea leaves falling from the edge of the stir-fry pan 2 can be reduced, and the discharge port 10 is used to facilitate the tea leaf feeding process.
[0032] The lifting assembly 21 includes a guide groove 215 disposed inside the column 11. A sliding column 213 is fixedly connected inside the guide groove 215. A first moving block 214 is slidably connected to the outside of the sliding column 213. One side of the first moving block 214 is connected to the L-shaped plate 14. Support seats 211 are fixedly connected to the top and bottom of one side of the guide groove 215. A lifting cylinder 212 is fixedly installed at the bottom of the lower support seat 211. The top of the lifting cylinder 212 passes through the support seat 211 and is connected to the first moving block 214. Figure 1 , Figure 2 As shown, when the tea leaves are finished being stir-fried and need to be unloaded, the lifting oil cylinder 212 can be used to drive the first moving block 214 to slide along the axis of the sliding column 213, so that the stirring blades 18 below one end of the L-shaped plate 14 can leave the inside of the stir-frying pot 2, thus avoiding the stirring blades 18 from obstructing the tea leaf unloading process.
[0033] The second drive assembly 19 includes a second motor 191 fixed to the top of one end of the L-shaped plate 14. The top end of the first drive shaft 16 passes through the L-shaped plate 14 and is connected to the output end of the second motor 191. A reinforcing sleeve 192 is coaxially provided on the outer side of the first drive shaft 16. The top end of the reinforcing sleeve 192 is connected to the L-shaped plate 14. The first drive shaft 16 is rotatably connected to the inner wall of the reinforcing sleeve 192. Figure 1 , Figure 2 As shown, the second motor 191 can drive the stir-frying blades 18 located at the bottom of the second drive shaft 17 to perform the stir-frying of tea leaves. The reinforcing sleeve 192 can enhance the overall support strength of the first drive shaft 16 and improve the working stability of the stir-frying blades 18.
[0034] The bottom of the L-shaped plate 14 is provided with a reinforcing plate 15 to make the stir-frying blades 18 work more stably. Figure 1 , Figure 2As shown, by setting the reinforcing plate 15, the support strength at the right angle of the L-shaped plate 14 can be enhanced, thus preventing the stir-frying blade 18 from malfunctioning due to bending of the L-shaped plate 14.
[0035] Working principle: First, the staff pours the tea leaves to be stir-fried into the stir-frying pot 2. Then, the second drive component 19 drives the stir-frying blades 18 located at the bottom of the second drive shaft 17 to stir-fry the tea leaves. After the tea leaves are stir-fried, the stir-frying blades 18 below one end of the L-shaped plate 14 can be removed from the stir-frying pot 2 by the lifting component 21. Then, the first drive component 7 drives the entire stir-frying pot 2 to tilt towards the tea collection container with the rotating shaft 6 as the center. This facilitates the feeding process. When it is necessary to disassemble and clean the stir-frying blades 18, the restriction on the second drive shaft 17 can be released by the docking component 20, and the stir-frying blades 18 can be removed for cleaning and maintenance. This not only reduces the difficulty of disassembling and assembling the stir-frying blades 18, but also achieves dual positioning of the second drive shaft 17, making the stir-frying blades 18 more stable in operation.
