[0026] Please see Figures 1-2 and Figure 4 This utility model provides a technical solution: an automated stir-frying device for red oil broad beans, including a stir-frying device 1, on which a stir-frying component 2 is installed;
[0027] The stir-frying device 1 includes a base 101 with casters at the bottom, a support 102 fixedly connected to the top of the base 101, a placement platform 103 fixedly connected to the top of the base 101 at the side of the support 102, and a wok 104 placed on the placement platform 103.
[0028] The stir-frying component 2 includes two sets of annular grooves 201 symmetrically fixed to the top of the support 102, and the annular grooves 201 are located directly above the wok 104. A threaded ring 202 is rotatably connected inside the annular groove 201. A first rotating shaft 206 is rotatably connected between each set of annular grooves 201 at the top of the support 102. One threaded ring 202 and the surface of the first rotating shaft 206 are fitted with gears 203, and the two gears 203 are meshed. The other threaded ring 202 and the surface of the threaded ring 202 are fitted with first belt pulleys 211, and the two first belt pulleys 211 are connected by a first belt 212. A first servo motor 205 is installed above the first rotating shaft 206 by a clamp, and the output end of the first servo motor 205 is connected to the first rotating shaft 206. A threaded shaft 204 of the tube support 102 is threadedly connected inside the threaded ring 202, and a spatula 207 is movably connected to the bottom end of the threaded shaft 204.
[0029] Please see Figure 3 and Figure 5 The top of the spatula 207 is fixedly connected to a first connecting rod 208, the top of the first connecting rod 208 is fixedly connected to a U-shaped plate 209, the inner wall of the U-shaped plate 209 is fixedly connected to a connecting shaft 210, and the bottom end of the threaded shaft 204 is rotatably connected to the surface of the connecting shaft 210 through a ferrule. The bottom end of the bracket 102 is located in the middle of the four first connecting rods 208 and is rotatably connected to a second rotating shaft 213. The bottom end of the second rotating shaft 213 is threadedly connected to a second connecting rod 214, and the side wall of the bottom end of the second connecting rod 214 is fixedly connected to a scraper 215, which contacts the inner wall of the wok 104.

[0030] By setting the stir-frying component 2, after the wok 104 is placed on the placement platform 103 and locked in place, the red oil bean paste can be processed. At this time, the first servo motor 205 can be turned on to drive the first rotating shaft 206, and through two gears 203, one of the threaded rings 202 will rotate in the opposite direction. The other threaded ring 202 will rotate synchronously through the first belt pulley 211 and the first belt 212. At this time, the two opposing threaded shafts 204 move horizontally up and down through the rotation of the threaded ring 202, pushing the spatula 207 downward. The spatula 207 and the threaded ring 204 move horizontally up and down. The textured shaft 204 is movably connected, and as it moves downwards, it can fit against the inner wall of the wok 104 to stir-fry the red oil bean paste. Meanwhile, two sets of spatulas 207 move up and down in a staggered manner to continuously stir-fry the bean paste evenly. During this process, after a period of time, both sets of spatulas 207 can be moved upwards and away from the wok 104. At this time, the second servo motor 216 can be activated to drive the second rotating shaft 213, causing the scraper 215 to scrape against the inner wall of the wok 104, removing the bean paste adhering to the sides. This effectively achieves the effect of automatically and evenly stir-frying the red oil bean paste from all directions and angles.
[0031] like Figures 1-2 As shown, a material assembly 3 is installed on the side wall of the placement platform 103. The material assembly 3 includes a force-bearing plate 301 symmetrically fixed to the side wall of the placement platform 103. A support rod 303 is symmetrically fixedly connected to the top of the force-bearing plate 301. A third rotating shaft 304 passes through the top of the interactive end of the support rod 303. The end of the third rotating shaft 304 away from the support rod 303 is rotatably connected to the side wall of the wok 104. A support plate is fixedly connected to the side end of one of the force-bearing plates 301. A third servo motor 302 is fixedly connected to the support plate. A fourth rotating shaft is rotatably connected to the side end of the force-bearing plate 301.

The two second belt pulleys 305 are connected to each other by a second belt 306. The outlet end of the third servo motor 302 is connected to the fourth rotating shaft.
[0032] By setting the material component 3, after the processing of red oil broad beans is completed, the spatula 207 can be raised, the third servo motor 302 can be turned on to drive the fourth rotating shaft to rotate, and the third rotating shaft 304 can be driven to rotate through the second belt pulley 305 and the second belt 306, thereby rotating and tilting the wok 104 to unload the processed red oil broad beans, and also to facilitate the cleaning of the wok 104 later.
[0033] The working principle of the above embodiment is as follows: First, after the wok 104 is placed on the placement platform 103 and locked in place, the red oil bean paste can be processed. At this time, the first servo motor 205 can be turned on to drive the first rotating shaft 206, and through the two gears 203, one of the threaded rings 202 will rotate in the opposite direction. The other threaded ring 202 will rotate synchronously through the first belt pulley 211 and the first belt 212. At this time, the two opposing threaded shafts 204 move horizontally up and down through the rotation of the threaded rings 202, pushing the spatula 207 downward. The spatula 207 is movably connected to the threaded shaft 204. During the downward movement, it can fit against the inner wall of the wok 104 to stir-fry the red oil bean paste. The two sets of spatulas 207 are staggered. The stir-fryer moves downwards continuously to stir-fry the red oil bean paste evenly. During this process, after a period of time, both sets of spatulas 207 can be moved upwards away from the wok 104. At this time, the second servo motor 216 can be turned on to drive the second rotating shaft 213, so that the scraper 215 scrapes against the inner wall of the wok 104 to scrape off the bean paste adhering to the side. After the red oil bean paste is processed, the spatulas 207 can be raised, and the third servo motor 302 can be turned on to drive the fourth rotating shaft to rotate. The third rotating shaft 304 is then rotated through the second belt pulley 305 and the second belt 306, which rotates the wok 104 to tilt it, thus unloading the processed red oil bean paste and facilitating the cleaning of the wok 104 later.
