[0025] Embodiment: A physical experiment stirring device with a wall scraping function, such as Figure 1-Figure 3As shown, it includes a stirring tank 1, the bottom of the stirring tank 1 is connected to a discharge port 101, the bottom of the discharge port 101 is connected to a mixing drum 3, one side of the mixing drum 3 is fixedly connected to a first motor 301, the output shaft end of the first motor 301 is located in the inner cavity of the mixing drum 3 and is fixedly connected to a mixing rod 302, and a spiral blade 303 is fixedly connected to the mixing rod 302, and the spacing of the spiral blade 303 close to the end of the first motor 301 is greater than the spacing away from the end of the first motor 301. By designing that the spacing of the spiral blade 303 changes from wide to narrow, the pressure of the spiral blade 303 gradually increases, which can increase the friction and extrusion between the blades, so that the mixing effect is better, and a tank cover 103 is attached to the top of the stirring tank 1, and a connecting hole 102 is opened in the center of the tank cover 103. The tank cover 103 is located on one side of the connecting hole 102 and is connected to a Y-shaped feeding hopper 2 The hopper 2 is connected to the inner cavity of the stirring tank 1, and a mounting frame 401 is installed on the top of the tank cover 103. A second motor 4 is fixedly installed on the mounting frame 401. An electric push rod 5 is fixedly connected to the output shaft end of the second motor 4. The bottom of the extended end of the electric push rod 5 is adapted to the connecting hole 102 and is detachably connected to a stirring rod 6. C-shaped blades 601 are fixedly connected to the two side wall surfaces of the stirring rod 6. The openings of the two C-shaped blades 601 are opposite, and a plurality of through holes 602 are evenly spaced on the two C-shaped blades 601. The C-shaped blades 601 are designed into a C-shaped structure, so that a variety of liquids to be mixed can be better stirred to promote the mixing process, and by cooperating with the through holes 602, the vortex during stirring can be increased, thereby mixing the liquids more effectively. When the blades need to be replaced, the tank cover 103 is opened, the stirring rod 6 is removed, and the blades are replaced.

[0026] A U-shaped mounting frame 7 is fixedly connected to the side wall surfaces of the two C-shaped blades 601 that are away from each other. Limiting grooves 701 are provided on the upper and lower sides of the mounting frame 7. The inner cavities of the two limiting grooves 701 are slidably connected to limiting blocks 702. A mounting plate 703 is fixedly connected to the wall surfaces opposite to the two limiting blocks 702. A plurality of reset springs 704 are fixedly connected to the inner cavity of the mounting frame 7. The other end of the reset spring 704 is fixedly connected to the wall surface of the mounting plate 703 close to the reset spring 704. A scraper 705 and a cleaning brush 706 are respectively fixedly connected to the wall surface of the mounting plate 703 away from the reset spring 704.

[0027] The working principle of this utility model:

[0028] When in use, the material to be mixed is poured into the inner cavity of the mixing tank 1 through the hopper 2. Through the cooperation of the return spring 704, the mounting plate 703, the limit block 702, the scraper 705 and the cleaning brush 706, the scraper 705 can remove large pieces of solid matter, while the cleaning brush 706 cleans fine solid matter. The cooperation of the two can not only help clean the solid matter on the inner wall of the mixing tank 1, but also can effectively scrape the material on the tank wall back to the mixing center, thereby ensuring the uniformity of the mixture and improving the mixing effect.

[0029] When in use, the second motor 4 and the electric push rod 5 are started. The operation of the second motor 4 can drive the electric push rod 5 to rotate, which can drive the stirring rod 6 to rotate, and then the C-shaped blade 601 stirs and mixes the liquid. As the extended end of the electric push rod 5 continues to rise and fall, the C-shaped blade 601 on the stirring rod 6 can be driven to rise and fall continuously, and the liquids at different positions in the inner cavity of the stirring tank 1 are fully mixed. At the same time, the spiral blade 303 fully mixes the materials, so that the mixing and stirring effect is better.

[0030] When in use, the pressure of the spiral blades 303 gradually increases due to the design that the spacing between the spiral blades 303 changes from wide to narrow, which can increase the friction and squeezing effect between the blades and assist the mixing effect.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.
