The shape of the piston 2024 is rectangular, the shape of the hollow shell 1032 is adapted to the shape of the piston 2024, the piston 2024 is arranged in the hollow shell 1032, and third magnetic plates 2023 are installed on both sides of the piston 2024; The self-cleaning magnetic stirring assembly 201 includes a rotating shaft 2011, and a plurality of second stirring blades 2012 are fixedly connected to the outside of the rotating shaft 2011. The rotating shaft 2011 is rotatably mounted on a slide rail 2018 and a bracket 2017 through a bearing. The slide rail 2018 is slidably connected to the dovetail end of the side scraper 1041. Two scrapers 2019 are fixedly connected to one side of the slide rail 2018, and the scrapers 2019 are arranged on the side scraper 1041. A guide rail 2016 is fixedly connected to the bottom of the bracket 2017, and the guide rail 2016 slides on the hollow shell 1032. A second magnetic plate 2015 is fixedly connected to one side of the guide rail 2016, and the second magnetic plate 2015 is magnetically attracted to the third magnetic plate 2023. Notches are also provided on both side walls of the guide rail 2016, and the guide rail 2016 is slidably connected to two guide bars 1036 through the two notches, and the guide bars 1036 are fixedly connected to the hollow shell 1032.

[0027] In this embodiment, the hollow shell 1032 is driven to rotate by the motor 1031, so that the hollow shell 1032 drives the nut 2022 and the screw 2021 through the piston 2024, so that the piston 2024 is displaced, and the piston 2024 is magnetically attracted between the third magnetic plate 2023 and the second magnetic plate 2015, so that the guide rail 2016 can be displaced, and the rotating shaft 2011 drives the scraper 2019 to move through the slide rail 2018, so that the scraper 2019 moves on the side scraper 1041. The side scraper 1041 can be cleaned by sliding, thereby satisfying the automatic cleaning of the side scraper 1041. When the piston 2024 moves upward, the piston 2024 can guide the material into the hollow shell 1032 through the one-way liquid inlet end 1034. When the piston 2024 moves downward, the material can be discharged through the one-way output pipe 1035, so that the material can be transported from bottom to top, thereby making the material mixing more uniform and avoiding stratification, further achieving the convenience of cleaning while improving the mixing efficiency.

[0028] Working principle: the hollow shell 1032 is driven to rotate by the motor 1031, and the hollow shell 1032 drives the first stirring blade 1033 to stir the material. At the same time, the hollow shell 1032 drives the piston 2024 to rotate, so that the nut 2022 and the screw 2021 are threadedly transmitted, so that the nut 2022 drives the piston 2024 to move, and when the piston 2024 moves downward, the third magnetic plate 2023 and the second magnetic plate 2015 are magnetically attracted, and the second magnetic plate 2015 moves with the third magnetic plate 2023, so that the guide rail 2016 and the rotating shaft 2011 are displaced. Secondly, the piston 2024 is displaced, so that the rope 2036 is released by the rope drum 2031, and the rope drum 2031 also drives the torsion spring 2034 to twist, so that the rope drum 2031 drives the fourth magnetic plate 2032 to rotate, so that the fourth magnetic plate 2032 and the first magnetic plate The force plate 2013 is magnetically attracted, so that the first magnetic plate 2013 rotates following the fourth magnetic plate 2032, so that the disc 2014 drives the rotating shaft 2011 to rotate, and the rotating shaft 2011 drives the second stirring blade 2012 to rotate to perform displacement-type stirring of materials. When the rope 2036 is completely released, the second stirring blade 2012 is erected, and the elastic band 2037 is stretched at the same time, so that the second stirring blade 2012 is cleaned by two scrapers 1043. When the control motor 1031 is reversed to make the piston 2024 move upward, the torsion of the torsion spring 2034 drives the rope disc 2031 to reel in the rope 2036. At this time, the second stirring blade 2012 can be kept rotating again to stir the materials. When the rotating shaft 2011 is displaced, the rotating shaft 2011 also drives the scraper 2019 to move through the slide rail 2018, so that the scraper 2019 cleans the scraper.
