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 1-4 This utility model discloses a tea processing stir-frying mechanism, including a stir-frying structure 1, a driving structure 2 at the top of the stir-frying structure 1, the movable end of the driving structure 2 extending to the inside of the stir-frying structure 1, and a screening structure 3 installed at the bottom of the stir-frying structure 1.

[0027] The frying structure 1 includes a frying furnace 101, a feeding trough 102 is fixedly installed on the outside of the frying furnace 101, and four support frames 103 are provided on the outside of the frying furnace 101.

[0028] The drive structure 2 includes a drive cover 201, a sealing cover 202 is installed at the bottom of the drive cover 201, an external motor 203 is fixedly installed at the top of the drive cover 201, the output shaft of the external motor 203 extends to the bottom of the drive cover 201 and a drive gear 204 is fixedly installed thereon, a connecting shaft 205 is installed at the bottom of the drive gear 204, and the bottom of the connecting shaft 205 is rotatably connected to the top of the sealing cover 202.

[0029] A connecting rod 206 is fixedly sleeved on the outer side of the connecting shaft 205. A follower gear 207 is fixedly installed on the inner side of the other end of the connecting rod 206. The follower gear 207 meshes with the drive gear 204. A linkage rod 208 is fixedly installed at the bottom end of the follower gear 207. A stir-frying shaft 211 is fixedly sleeved on the surface of the linkage rod 208. The stir-frying shaft 211 is located inside the stir-frying furnace 101.

[0030] By setting up the drive structure 2, the external motor 203 can drive the follower rack 207 to drive the stirring shaft 211 on the surface of the linkage rod 208 through the drive gear 204 to continuously stir-fry the tea leaves inside the stir-frying structure 1. The entire stirring process does not require manual intervention, thus realizing the automation of tea stirring. This avoids the problem of tea leaves piling up when manually stirring in the traditional way, significantly improves the heat uniformity of the tea leaves during the stirring process, effectively shortens the stirring time of the tea leaves, ensures the quality of the tea leaves, and also improves production efficiency.

[0031] Specifically, a latch is provided on the outer side of the sealing cover 202, and the top of the frying oven 101 is movably engaged with the sealing cover 202 through the latch.

[0032] In this embodiment, the locking mechanism allows for easy fixing or disassembly of the sealing cover 202 to the roasting oven 101, facilitating maintenance and cleaning of the roasting oven 101 and improving ease of use. Simultaneously, the locking design ensures the stability between the sealing cover 202 and the roasting oven 101 during operation, preventing heat loss or tea splattering due to poor sealing.

[0033] Specifically, a vertical rod is installed at the top of the sealing cover 202, and the top of the vertical rod is fixedly connected to the bottom of the drive cover 201.

[0034] In this embodiment, the vertical rod further enhances the connection stability between the sealing cover 202 and the drive cover 201, making the entire drive structure 2 more stable during operation and improving the overall stability and service life of the stir-frying mechanism. At the same time, the vertical rod design simplifies the assembly process between the sealing cover 202 and the drive cover 201, making the assembly and maintenance of the stir-frying mechanism more convenient and faster.

[0035] Specifically, an annular groove 210 is provided on the inner side of the sealing cover 202, and a guide block 209 is fixedly sleeved on the surface of the linkage rod 208, with the guide block 209 located inside the annular groove 210.

[0036] In this embodiment, by setting the annular groove 210 and the guide block 209, the automatic and revolving motion of the linkage rod 208 can be guided and limited, ensuring that the linkage rod 208 can maintain a stable and precise motion trajectory during the stir-frying process, thereby improving the uniformity and stability of the stir-frying shaft 211 in stir-frying the tea.

[0037] Meanwhile, the cooperation between the guide block 209 and the annular groove 210 also enhances the connection strength between the sealing cover 202 and the linkage rod 208, avoiding loosening or damage caused by vibration during the stir-frying process, and further improving the working stability and service life of the stir-frying mechanism.

[0038] Specifically, a ball joint 212 is provided at the center of the bottom end of the inner wall of the frying furnace 101, and the bottom end of the linkage rod 208 is movably connected to the top end of the ball joint 212.

[0039] In this embodiment, by setting the ball joint 212, the linkage rod 208 can more flexibly adapt to the stir-frying requirements at different angles during the stir-frying process, ensuring that the stir-frying shaft 211 can evenly stir-fry the tea leaves from all directions. The design of the ball joint 212 not only improves the uniformity and efficiency of stir-frying, but also enhances the overall flexibility and durability of the stir-frying mechanism.

[0040] In addition, the ball joint 212 has self-lubricating properties, which can reduce friction and wear during stir-frying and extend the service life of the stir-frying mechanism. At the same time, the material of the ball joint 212 has also undergone special treatment, possessing high temperature resistance and corrosion resistance, and can maintain stable stir-frying performance in harsh working environments.

[0041] Specifically, the screening structure 3 includes a feeding box 301, the top of which is fixedly installed to the bottom of the roasting furnace 101. A conveying cylinder 302 is fixedly connected to the inner side of the feeding box 301. The conveying cylinder 302 is connected to the furnace door of the roasting furnace 101. A filter screen 303 is provided on the surface of the conveying cylinder 302. A screening port is opened at the bottom of the feeding box 301. An internal motor 304 is fixedly installed on the inner wall of the feeding box 301. A conveying auger 305 is fixedly installed on the output shaft of the internal motor 304. The conveying auger 305 is located inside the conveying cylinder 302. An outlet channel 306 is provided at the output port of the conveying cylinder 302.

[0042] In this embodiment, when the screening structure 3 is working, the built-in motor 304 drives the conveying auger 305 to rotate. The tea leaves fall from the furnace door of the roasting furnace 101 into the conveying cylinder 302. After being screened by the filter screen 303, tea fragments and other impurities are filtered out. At the same time, the rotation of the conveying auger 305 pushes the screened tea leaves toward the output port of the conveying cylinder 302, and finally discharges them through the discharge channel 306, thus realizing the automated screening and discharge of tea leaves.

[0043] When in use, the user can place the heating device under the frying oven 101. The heating device used can be an electric heating device or a liquefied gas heating device in the prior art. The frying oven 101 can be made of heat-conducting metal material so that the frying oven 101 can conduct heat so that the tea leaves are heated during the frying process.

[0044] Then, the staff put the tea leaves into the frying furnace 101 through the feeding trough 102, and then started the external motor 203. The output shaft of the external motor 203 drives the drive gear 204 to rotate. The drive gear 204 drives the follower rack 207 to revolve and rotate on its own axis through meshing. The follower rack 207 then drives the linkage rod 208 and the frying shaft 211 to fry inside the frying furnace 101.

[0045] Because the rotation of the stirring shaft 211 stirs the tea leaves evenly, it ensures that the tea leaves are heated evenly during the stir-frying process, and avoids the problem of uneven stir-frying caused by the tea leaves piling up together.

[0046] Meanwhile, since the stirring shaft 211 is movably connected to the bottom end of the inner wall of the frying furnace 101 through the ball joint 212, the stirring shaft 211 can stir-fry at multiple angles during the stir-frying process, which further improves the uniformity and efficiency of the stir-frying.

[0047] After the stir-frying is finished, the furnace door of the frying furnace 101 is opened. Under the action of centrifugal force and the push of the stir-frying shaft 211, the stir-frying shaft 211 can push the tea leaves in the frying furnace 101 into the conveyor cylinder 302. Then, the built-in motor 304 starts, driving the conveying auger 305 to start rotating. The blades of the conveying auger 305 continuously push the tea leaves forward. During the conveying process, the tea leaves are screened by the filter screen 303 to ensure that impurities and fragments are completely separated. Finally, the screened high-quality tea leaves are smoothly discharged through the outlet channel 306, completing the entire stir-frying and screening process.

[0048] In summary, this tea processing stirring mechanism, through the setting of the drive structure 2, utilizes an external motor 203 to drive the follower gear 207 via the drive gear 204 to drive the stirring shaft 211 on the surface of the linkage rod 208 to continuously stir-fry the tea leaves located inside the stirring structure 1. The entire stirring process requires no manual intervention, thus achieving automation of tea stirring. This avoids the problem of tea leaves easily piling up during traditional manual stirring, significantly improves the heat uniformity of the tea leaves during the stirring process, effectively shortens the stirring time, ensures tea quality, and also improves production efficiency.

[0049] It should be noted that the specific models and specifications of the external motor 203 and the internal motor 304 in the tea processing stirring mechanism need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0050] Furthermore, the power supply and operating principle of the external motor 203 and the internal motor 304 in the tea processing stirring mechanism are clear to those skilled in the art, and will not be described in detail here.

[0051] Furthermore, the working principle and wiring method of the external motor 203 and the internal motor 304 in the tea processing stirring mechanism are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.
