[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0018] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an automatic stirring device for turning over materials during the fermentation of fermented bean curd. It includes a mixing component, comprising a fermentation tank 10 with graduation marks 14 on its inner wall, a stirring assembly 11 for stirring the fermented bean curd inside the fermentation tank 10, a conversion assembly 12 for adjusting the mixing direction on the stirring assembly 11 to achieve uniform mixing of the fermented bean curd, and a power assembly 13 for driving the stirring assembly 11 at the bottom of the fermentation tank 10. A cleaning component includes a cleaning assembly 20 installed on the stirring assembly 11, which is used to rinse the inner wall of the fermentation tank 10. A water supply assembly 21 is installed at the top of the fermentation tank 10 to inject water into the cleaning assembly 20 for continuous water spraying and cleaning.

[0019] The conversion component 12 is located inside the fermentation tank 10 at the top, above the scale mark 14, while the highest point of the stirring component 11 is below the scale mark 14, and the amount of fermented bean curd is kept below the scale mark 14.

[0020] Furthermore, the stirring assembly 11 includes a lower shaft 111 rotatably connected to the bottom of the fermentation tank 10. A pair of arc-shaped scrapers 112 are symmetrically fixedly connected to the bottom side wall of the lower shaft 111, and the arc-shaped scrapers 112 are in contact with the inner wall and bottom wall of the fermentation tank 10. A first mixing paddle 113 is fixedly connected to the side of the arc-shaped scraper 112 near the lower shaft 111.

[0021] The fermenter 10 has an upper shaft 116 rotatably connected to the top wall. A pair of support plates 114 are symmetrically fixed to the side wall of the upper shaft 116. A set of second mixing paddles 115, which are intersected with the first mixing paddle 113, are fixedly connected to the bottom of the support plates 114.

[0022] Among them, the bottom of the arc-shaped scraper 112 is arc-shaped to match the bottom of the fermenter 10, and the side is straight to contact the side wall of the fermenter 10. The support plate 114 and the second mixing paddle 115 located on the outermost side are an integral structure.

[0023] Furthermore, the conversion assembly 12 includes two first shafts 121 respectively sleeved on the surfaces of the lower shaft 111 and the upper shaft 116. The two first shafts 121 are provided with rotating shafts 126 on their sides. The rotating shafts 126 are sleeved with second shafts 124. The two first shafts 121 and the second shafts 124 are connected by a connecting rod 125. The lower shaft 111 and the upper shaft 116 are each sleeved with a first bevel gear 122 at one end close to each other. The rotating shaft 126 is sleeved with a second bevel gear 123 at one end close to the first bevel gear 122. The two first bevel gears 122 are respectively meshed with the second bevel gear 123.

[0024] Furthermore, the power assembly 13 includes a control cabinet 131 installed at the bottom of the fermenter 10, a servo motor 132 fixedly connected to the control cabinet 131, and the output end of the servo motor 132 connected to the lower shaft 111.

[0025] The control cabinet 131 is electrically connected to the servo motor 132 and the solenoid valve.

[0026] In use, the servo motor 132 is activated via the control cabinet 131 to drive the lower shaft 111 to rotate clockwise, thereby causing the arc-shaped scraper 112 and the first mixing paddle 113 to rotate and stir the fermented bean curd in the fermentation tank 10. During stirring, the arc-shaped scraper 112 contacts the bottom and inner wall of the fermentation tank 10, thus uniformly stirring the fermented bean curd that has settled at the bottom, while scraping off the fermented bean curd that is stuck to the inner wall. However, during the rotation of the lower shaft 111, the meshing of the two first bevel gears 122 and the second bevel gear 123 further facilitates the mixing of the fermented bean curd. The two first shafts 121 are connected to the second shaft 124 via connecting rod 125. At this time, the upper shaft 116 can be driven to rotate counterclockwise, thereby driving the second mixing paddle 115, the arc scraper 112 and the first mixing paddle 113 to rotate synchronously in the opposite direction. The second mixing paddle 115, the arc scraper 112 and the first mixing paddle 113 are arranged in a staggered manner, which can uniformly stir the fermented bean curd. The amount of fermented bean curd in the fermentation tank 10 must not exceed the scale mark 14 to avoid affecting the use of the conversion component 12. Example 2

[0027] Reference Figures 2-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides... The cleaning assembly 20 includes a water injection tank 203 opened at the top of the upper shaft 116. The inner walls of the second mixing paddle 115 and the support plate 114 are both provided with water storage tanks 204 that are connected to each other, and the water storage tanks 204 are connected to the water injection tank 203. Multiple nozzles 201 are equidistantly opened at one end of the second mixing paddle 115 near the inner wall of the fermentation tank 10. A protective plate 202 is snapped onto the surface of the nozzles 201 at the side end of the second mixing paddle 115.

[0028] The protective plate 202 has a U-shaped structure, which is snapped and fitted to the side wall of the second mixing paddle 115 and abuts against the water spray hole of the nozzle 201.

[0029] Furthermore, the water supply assembly 21 includes a delivery pipe 211 connected to the water injection tank 203 at the top of the upper shaft 116, and the delivery pipe 211 extends to the outside of the fermentation tank 10. The input end of the delivery pipe 211 is connected to a water tank, and a solenoid valve 212 is installed at the connection between the delivery pipe 211 and the upper shaft 116.

[0030] The conveying pipe 211 extends into the fermenter 10 and is rotatably and sealed to the water injection tank 203, so that water can be continuously conveyed as the upper shaft 116 rotates.

[0031] When in use, after the fermentation of fermented bean curd is completed, the fermented bean curd is removed. Then, the solenoid valve 212 can be opened to open the delivery pipe 211 to inject water into the water injection tank 203. After the water enters the water injection tank 203, it flows into the water storage tanks 204 on both sides and is sprayed out through the nozzle 201. The spray is sprayed on the inner wall of the fermentation tank 10. With the rotation and scraping of the arc-shaped scraper 112, the automatic cleaning can be achieved. When fermenting the fermented bean curd again, the protective plate 202 can be attached to the second mixing paddle 115 to protect the nozzle 201 and prevent it from contacting the fermented bean curd and causing blockage.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
