[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5This utility model provides a novel mixer scraper with easy-to-replace scraper head, comprising a device body 10, on which a mixing tank 11 is mounted. A rotating shaft 13 is rotatably connected to the center of the mixing tank 11. A connecting rod 15 is fixedly connected to one side of the rotating shaft 13. A mounting plate 16 is fixedly connected to the end of the connecting rod 15. A sliding groove 21 is formed on the left side of the mounting plate 16, the opening diameter of the sliding groove 21 being smaller than the inner diameter of the groove. Three first through holes 22 are formed on the right side of the mounting plate 16. The sliding groove 21 communicates with the first through holes 22. A scraper 23 is placed within the sliding groove 21. A scraper head 24 is magnetically attached to the left side of the scraper 23. The left side of the scraper head 24 is located within the slide groove 21, and the right side of the scraper head 24 extends from the slide groove 21 and fits against the inner wall of the mixing tank 11. An installation groove 25 is formed in the center of the scraper 23, and a movable plate 29 is movably connected within the installation groove 25. A locking block 31 is fixedly connected to the right side of the movable plate 29, passing through the first through hole 22. During operation, the connecting rod 15 connects the rotating shaft 13 and the installation plate 16, serving as a force transmission and structural support, allowing the installation plate 16 to rotate synchronously with the rotating shaft 13. The installation plate 16 acts as the mounting carrier for the scraper 23, and its opening... The sliding groove 21 and the first through hole 22 are designed to achieve the positioning, installation, and fixation of the scraper 23. The sliding groove 21 is used to place the scraper 23, and its structure, with an opening diameter smaller than the inner diameter of the groove, can limit the scraper 23 and prevent it from falling off the opening during rotation. The first through hole 22 cooperates with the third through hole 27 of the scraper 23 to provide an insertion channel for the locking block 31. The scraper 23 is fixed to the mounting plate 16 by engaging the locking block 31. The scraper 23 magnetically attracts the scraper head 24 on the left side and is fixed to the mounting plate 16 on the right side by the locking block 31. It is the core component connecting the scraper head 24 and the mounting plate 16, and at the same time provides installation space for internal structures such as the movable plate 29. The scraper head 24 is directly attached to the inner wall of the mixing tank 11. As the mounting plate 16 rotates, it scrapes off the residual material on the tank wall. The magnetic connection design allows for quick and easy replacement. The mounting groove 25 is opened inside the scraper 23, providing installation and movement space for components such as the movable plate 29, the limiting rod 28, and the first spring 30. The movable plate 29 connects the first spring 30 and the locking block 31. By sliding left and right, the locking block 31 moves in and out of the first through hole 22, realizing the fixing and disassembly of the scraper 23. The locking block 31 is fixed on the right side of the movable plate 29. By passing through the third through hole 27 and the first through hole 22, it clamps and fixes the scraper 23 and the mounting plate 16, which is the key component for the connection between the two.

[0027] Furthermore, such as Figure 5As shown, a second through hole 26 is provided on the upper surface of the scraper 23, which communicates with the mounting groove 25. A third through hole 27 is provided on the right side of the scraper 23, which communicates with the mounting groove 25. The third through hole 27 corresponds to the position of the first through hole 22. The locking block 31 passes through the third through hole 27. During operation, the second through hole 26 communicates with the mounting groove 25, allowing the adjusting rod 35 to pass through, which facilitates pushing the extrusion block 34. The third through hole 27 corresponds to the position of the first through hole 22, providing an insertion channel for the locking block 31, ensuring that the locking block 31 can smoothly pass through the scraper 23 and engage with the first through hole 22 of the mounting plate 16.

[0028] Furthermore, such as Figure 5 As shown, limiting rods 28 are fixedly connected to the upper and lower sides of the mounting groove 25. The movable plate 29 slides left and right on the limiting rods 28. A first spring 30 is fixedly connected to the left side of the mounting groove 25. Multiple first springs 30 are provided. The other end of the first spring 30 is fixedly connected to the movable plate 29. During operation, the limiting rods 28 are fixed to the upper and lower sides of the mounting groove 25 to restrict the movement direction of the movable plate 29, ensuring that the movable plate 29 can only slide left and right along the limiting rods 28 to avoid deviation. One end of the first spring 30 is fixed to the left side of the mounting groove 25, and the other end is connected to the movable plate 29. Under normal conditions, it provides a rightward elastic force to push the movable plate 29 to keep the locking block 31 in the locked state. When disassembling, it is stretched to store elastic force.

[0029] Furthermore, such as Figure 5 As shown, an extension plate 32 is fixedly connected to the right side of the mounting groove 25. The extension plate 32 is located on the right side of the movable plate 29. During operation, the extension plate 32 is fixed on the right side of the mounting groove 25 to provide a mounting support point for the second spring 33, and at the same time, it plays a right-side limiting role for the movable plate 29.

[0030] Furthermore, such as Figure 5 As shown, a second spring 33 is fixedly connected to the upper surface of the extension plate 32, and a pressing block 34 is fixedly connected to the top of the second spring 33. The pressing block 34 is an inverted trapezoid with its inclined surface close to the side of the movable plate 29. During operation, one end of the second spring 33 is fixed to the upper surface of the extension plate 32, and the other end is connected to the pressing block 34. Under normal conditions, it provides an upward elastic force to keep the pressing block 34 in the upper position. When the adjusting rod 35 is pressed, it is compressed and stores the elastic force. The pressing block 34 is an inverted trapezoid with its inclined surface close to the movable plate 29. When it moves down, it presses the movable plate 29 through the inclined surface to make it move to the left, causing the locking block 31 to disengage. When it moves up, it releases the pressure, allowing the movable plate 29 to reset under the action of the first spring 30.

[0031] Furthermore, such as Figure 5As shown, an adjusting rod 35 is fixedly connected to the top of the extrusion block 34. The adjusting rod 35 extends out of the second through hole 26. During operation, the top of the adjusting rod 35 extends out of the first through hole 22 for the operator to press. By driving the extrusion block 34 to move up and down, the locking and unlocking of the locking block 31 is controlled. It is the operating component for disassembling and installing the scraper 23.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, a motor 12 is fixedly connected to the top of the rotating shaft 13, and the rotating shaft 13 is fixedly connected to the output shaft of the motor 12. A stirring blade 14 is fixedly connected to the outer surface of the rotating shaft 13. During operation, the motor 12 serves as a power source, driving the rotating shaft 13 to rotate through the drive output shaft, providing power for the scraper 23 to scrape the material and the stirring blade 14 to stir the material. The stirring blade 14 rotates with the rotating shaft 13 to stir the material in the mixing tank 11, ensuring that the material is mixed evenly.

[0033] Working principle: Start motor 12, which drives shaft 13 to rotate. Shaft 13 drives stirring blade 14 to stir materials. At the same time, it drives mounting plate 16, scraper 23, and scraper head 24 to rotate synchronously through connecting rod 15. Scraper head 24 scrapes off residual materials by adhering to the inner wall of mixing tank 11. When scraper head 24 wears, press adjusting rod 35. Adjusting rod 35 drives extrusion block 34 to move down and compress second spring 33. Extrusion block 34 squeezes movable plate 29 through the left inclined surface, causing movable plate 29 to slide to the left along limit rod 28 and stretch first spring 30. At the same time, movable plate 29 drives locking block 31 to retract from first through hole 22 and third through hole 27. At this point, the scraper 23 is no longer fixed and can be removed from the groove 21 of the mounting plate 16. The old scraper head 24 is magnetically separated from the left side of the scraper 23 by hand or tool. Then, the new scraper head 24 is magnetically attracted to the scraper 23 to complete the replacement. Press the adjusting rod 35 to retract the locking block 31 into the mounting groove 25. Place the scraper 23 into the groove 21 and ensure that the third through hole 27 is aligned with the first through hole 22. Release the adjusting rod 35. The second spring 33 resets and pushes the squeezing block 34 and the adjusting rod 35 to move upward. The first spring 30 resets and pushes the movable plate 29 to move to the right, so that the locking block 31 passes through the third through hole 27 and the first through hole 22, thus completing the fixation of the scraper 23.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
