Specific embodiments
[0025] This part will describe the specific embodiments of the utility model in detail, and the preferred embodiments of the utility model are shown in the drawings, and the drawings are used to supplement the description of the text part in the form of graphics, so that people can intuitively and visually understand each technical feature and the overall technical scheme of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0026] Please refer to Figures 1-7 The utility model provides a kind of technical scheme: a planetary mixer with scraper structure, including cover 1 and lifting frame 25, the bottom of lifting frame 25 is movably connected with stirring cylinder 21, cover 1 is located on stirring cylinder 21, the top of cover 1 is fixedly connected with motor 2, the output end of motor 2 is rotatably connected with cover 1, one end of the output end of motor 2 is fixedly connected with rotating shaft 3 penetrating cover 1, the surface of rotating shaft 3 is fixedly connected with fixed plate one 4, the end of fixed plate one 4 away from rotating shaft 3 is fixedly connected with fixed pipe 9, the inner wall surface of fixed pipe 9 is provided with sliding rail 14, sliding rail 14 is inclined annular, fixed rod 12 is rotatably connected in the inside of fixed pipe 9, sliding pipe 13 is slidably connected on the surface of fixed rod 12, sliding pipe 13 is rotatably connected on the inner wall surface of fixed pipe 9, the surface of sliding pipe 13 is fixedly connected with fixed block 15, fixed block 15 is slidably connected on the inner wall surface of sliding rail 14, the side of fixed rod 12 is fixedly connected with limit block 16, limit block 16 is also slidably connected in the inside of sliding pipe 13, the end of sliding pipe 13 away from the inside of fixed pipe 9 is fixedly connected with stirring head 11, the top of fixed rod 12 is fixedly connected with gear 7, the inner wall surface of cover 1 is fixedly connected with tooth ring 8, tooth ring 8 is meshingly connected with gear 7.
[0027] When the motor 2 needs to be stirred, the output end of the motor 2 rotates to drive the rotating shaft 3 to rotate, which drives the fixed plate 4 to move, so that the fixed plate 4 drives the fixed tube 9 to move synchronously. When the rotating shaft 3 drives the fixed plate 4 to rotate, the gear 7 engaged with the gear ring 8 rotates, thereby driving the fixed rod 12 and the limiting block 16 to rotate. When the fixed rod 12 and the limiting block 16 rotate, the sliding tube 13 is driven to rotate. The limiting block 16 limits the sliding tube 13 to prevent the sliding tube 13 from rotating on the surface of the fixed rod 12. When the sliding tube 13 rotates, the fixed block 15 slides in the sliding rail 14. The sliding rail 14 is an inclined annular, so that one end of the sliding rail 14 is high and the other end is low. When the fixed block slides to the higher end of the sliding rail 14, the sliding tube 13 slides upward with the fixed block 15. When the fixed block 15 slides to the lower end of the sliding rail 14, the sliding tube 13 slides downward with the fixed block 15. Therefore, when the fixed block 15 slides in the sliding rail 14, the sliding tube 13 slides up and down on the surface of the fixed rod 12 and the limiting block 16, so that the sliding tube 13 drives the stirring head 11 to rotate and move up and down at the same time. Through this structure, the stirring head 11 can more uniformly stir the soil inside when rotating up and down, reducing the phenomenon of soil clumping, and can more uniformly mix different soils, thereby reducing the dead angle during stirring.
[0028] The top of the lifting frame 25 is fixedly connected with a lifting motor 24. The output end of the lifting motor 24 is fixedly connected with a threaded rod 23 penetrating through one end of the lifting frame 25. The surface of the threaded rod 23 is threadedly connected with a horizontal plate 22 which is slidingly connected to the inner wall surface of the lifting frame 25. The end of the horizontal plate 22 away from the lifting frame 25 is fixedly connected to the surface of the cover 1.
[0029] When the lifting motor 24 at the top of the lifting frame 25 is started to rotate its output end, the output end of the lifting motor 24 rotates to drive the threaded rod 23 to rotate. When the threaded rod 23 rotates, the horizontal plate 22 slides on the inner wall of the lifting frame 25. The horizontal plate 22 is limited to avoid deviation when it rises or falls. When the horizontal plate 22 rises, the cover 1 rises, and the motor 2 rises synchronously. At this time, the articles to be stirred are placed in the stirring cylinder 21. The lifting motor 24 is started to rotate reversely to drive the cover 1 to cover the stirring cylinder 21. At this time, the motor 2 can stir the articles in the stirring cylinder 21.
[0030] A sleeve 10 is rotatably connected to the surface of the fixed tube 9. The sleeve 10 is hollow. A threaded plate 20 is fixedly connected to the hollow inner wall of the sleeve 10. A slide rod 17 is fixedly connected to the end of the fixed tube 9 away from the fixed plate 4. The slide rod 17 is hollow. A striking rod 18 is slidably connected inside the end of the slide rod 17 away from the fixed tube 9. The end of the striking rod 18 away from the inside of the slide rod 17 is slidably connected to the surface of the threaded plate 20. The two ends of the spring 19 are fixedly connected to the fixed tube 9 and the striking rod 18 respectively.
[0031] When the stirring head 11 rotates, the threaded plate 20 presses the striking rod 18 into the slide bar 17. When the striking rod 18 enters the slide bar 17, it exerts a compressive force on the spring 19, causing it to deform and contract. When one end of the striking rod 18 slides to the highest point of the threaded plate 20, it no longer presses on that end of the striking rod 18. Therefore, when the spring 19 loses its compressive force, it expands and pushes the striking rod 18 to strike the stirring head 11. This continuous vibration prevents a large amount of mixing material from adhering to the surface of the stirring head 11, thus delaying the mixing process.
[0032] A fixing plate 5 is fixedly connected to the surface of the rotating shaft 3. The fixing plate 5 is L-shaped. A scraper 6 is fixedly connected to the side of the fixing plate 5 near the mixing drum 21. The scraper 6 is in contact with the inner wall of the mixing drum 21.
[0033] When the rotating shaft 3 rotates, it will drive the fixed plate 5 to rotate. Therefore, when the fixed plate 5 rotates, it will drive the scraper 6 to move on the inner wall of the mixing drum 21, thereby scraping the inner wall surface of the mixing drum 21 to prevent the inner wall of the mixing drum 21 from being attached to the material and thus preventing it from being fully mixed.
[0034] Working principle: when the need to stir, start the motor 2, the output end of motor 2 rotates and drives the rotating shaft 3, when the rotating shaft 3 drives the fixed plate 4 to move, so that the fixed plate 4 drives the fixed tube 9 to move synchronously, when the rotating shaft 3 drives the fixed plate 4 to rotate, the gear 7 meshing with the gear ring 8 will produce rotation, in turn drive the fixed rod 12 and the limiting block 16 to rotate, when the fixed rod 12 and the limiting block 16 rotate, the sliding tube 13 will be driven to rotate, the limiting block 16 limits the sliding tube 13, prevents the sliding tube 13 from rotating on the surface of the fixed rod 12, when the sliding tube 13 rotates, the fixed block 15 will slide in the slide rail 14, because the slide rail 14 is inclined annular, in turn makes the slide rail 14 one end high one end bottom, when the fixed block slides to the higher end of the slide rail 14, the sliding tube 13 slides upward with the fixed block 15, when the fixed block 15 slides to the lower end of the slide rail 14, the sliding tube 13 slides downward with the fixed block 15, in turn makes the fixed block 15 drive the sliding tube 13 to slide up and down on the surface of the fixed rod 12 and the limiting block 16 when sliding in the slide rail 14, so that the sliding tube 13 drives the stirring head 11 to rotate at the same time also moves up and down.
[0035] When the need to stir the article, start the lifting motor 24 at the top of the lifting frame 25 to make its output end rotate, when the output end of the lifting motor 24 rotates, the threaded rod 23 will be driven to rotate, when the threaded rod 23 rotates, the horizontal plate 22 will slide in the inner wall of the lifting frame 25, in turn avoids the deviation of the horizontal plate 22 when ascending or descending, limits it, when the horizontal plate 22 ascends, the cover 1 will ascend, in turn the motor 2 will ascend synchronously with the cover 1.
[0036] When the stirring head 11 rotates, the threaded plate 20 will extrude the knocking rod 18 to make it enter the inside of the slide rod 17, when the knocking rod 18 enters the inside of the slide rod 17, the spring 19 will be extruded to make it deform and contract, when the one end of the knocking rod 18 slides to the highest position of the threaded plate 20, the one end of the knocking rod 18 will not be extruded any more.
[0037] When the rotating shaft 3 rotates, the fixed plate 5 will be driven to rotate, so when the fixed plate 5 rotates, the scraper 6 will move on the inner wall of the stirring cylinder 21.
[0038] The above embodiment of the utility model is described in detail in combination with the drawings, but the utility model is not limited to the above embodiment, within the knowledge range possessed by ordinary skilled in the art, various changes can be made without departing from the purpose of the utility model.
