Description

Technical Field

[0001] This invention relates to the field of slurry equipment technology, specifically to a local slurry homogenization device for cement mixing. Background Technology

[0002] In the process of cement construction and slurry mixing, in order to obtain a slurry with good quality and sufficient uniformity, it is necessary to use specific equipment for local slurry homogenization. Traditional slurrying is done with hand-held slurrying equipment, which is usually operated by the operator directly holding the motor part to carry out the mixing operation. In actual use, this equipment has many inconveniences.

[0003] Because the counter-torque generated when the motor starts and runs at high speed is large, operators need to apply continuous force to stabilize the equipment, which is labor-intensive and easy to cause fatigue. In addition, since most existing equipment does not have the function of automatically adjusting the stirring range according to the container size, the blades are prone to hitting the inner wall of the container during the stirring process, causing equipment wear or even container damage, which poses a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a local slurry homogenization device for cement mixing process, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a local slurry homogenization device for cement mixing process, comprising a frame and a slurrying mechanism, wherein a moving mechanism, a dual-axis balancing mechanism and a positioning mechanism are provided on the frame, the dual-axis balancing mechanism is installed on the moving mechanism, and the dual-axis balancing mechanism and the positioning mechanism are connected to the control system circuit;

[0006] The dual-axis balancing mechanism includes a lifting platform and an angle adjustment assembly. The lifting platform is connected to the moving mechanism, the angle adjustment assembly is installed on the lifting platform, and the pulping mechanism is installed on the angle adjustment assembly.

[0007] The positioning mechanism includes a pair of positioning clamps, a pulley reversing module, and a power module, wherein the pulley reversing module is connected between the pair of positioning clamps and the power module.

[0008] Furthermore, the angle adjustment assembly includes a transfer frame, a machine base plate, and a pair of limiters. The pair of limiters are respectively installed in the lifting platform and the transfer frame. The transfer frame is rotatably installed on the lifting platform, and the machine base plate is rotatably installed in the middle of the transfer frame. The rotation axis of the machine base plate is perpendicular to the rotation axis of the transfer frame.

[0009] The frame includes a support, and the moving mechanism includes at least one pair of guide columns. The at least one pair of guide columns is mounted on the support. The lifting platform is slidably connected to the at least one pair of guide columns. The lifting platform slides up and down along the guide columns. The limiter restricts the rotation range of the protrusion. The auxiliary mechanism supports the movement of the pulper. Therefore, the auxiliary mechanism and the frame bear the reverse torsional force generated by the power component during pulping. The operator saves more effort during pulping. The auxiliary mechanism effectively counteracts the reverse torsional force when the motor is running, greatly reducing the operator's machine-holding load and improving operating comfort and stability.

[0010] Furthermore, both the adapter frame and the machine base plate are provided with a protrusion, one of the limiters is located on the side of the lifting platform near the protrusion of the adapter frame, and the other limiter is located on the side of the adapter frame near the protrusion of the machine base plate.

[0011] Furthermore, the limiter in the lifting platform includes a pair of notched annular blocks, a small bevel gear, and a first driving member. The pair of notched annular blocks are connected to the lifting platform. The notched annular blocks have toothed grooves on their sides that are close to each other. The first driving member is fixedly installed in the lifting platform. The small bevel gear is connected to the first driving member. The small bevel gear is meshed with the toothed grooves of the pair of notched annular blocks. The pair of notched annular blocks block the protrusion.

[0012] The limiters in the adapter frame have the same structure and installation method as the limiters in the lifting platform. The container size signal drives the first driving component in the two limiters to move simultaneously. The small bevel gear drives a pair of notched annular blocks to move in opposite directions, so that the pair of notched annular blocks simultaneously approach or move away from the protrusion. If the notched annular blocks simultaneously approach the protrusion, the movement range of the dual-axis balancing mechanism is reduced. If the notched annular blocks simultaneously move away from the protrusion, the movement range of the dual-axis balancing mechanism is increased. The limiters restrict the movement range of the stirring shaft. When the operator is performing pulping, it effectively prevents the stirring shaft from colliding with the inner wall of the container during high-speed stirring. On the one hand, it ensures that the stirring shaft stirs within the container to the maximum extent, and on the other hand, it prevents damage to the stirring shaft and the container. An adjustable limiter is used to automatically or manually set the swing range of the stirring shaft according to the container size, avoiding collision between the paddle and the inner wall of the container. This protects the equipment and the container and ensures that the stirring range is maximized.

[0013] Furthermore, the moving mechanism also includes a counterweight module and an operating handle. The operating handle is located at the bottom of the machine platform, and the counterweight module is mounted on the support. The counterweight module includes an upper steel cable, several upper guide wheels, and a counterweight block. One end of the upper steel cable is connected to the lifting platform, and the other end of the upper steel cable passes over all the upper guide wheels and is connected to the counterweight block. The counterweight block is slidably mounted on the side of the support, and the weight of the counterweight block is slightly greater than the weight of the other end of the upper steel cable. The operator presses down the auxiliary mechanism using the operating handle, inserts the stirring shaft into the slurry container, and moves the operating handle up and down to make the stirring shaft tumble the slurry in the container. By deflecting the machine platform using the operating handle, the operator rotates the stirring shaft in the container to slurry. The operator uses their other hand to slide the grip sleeve, causing the paddle to repeatedly deflect and slurry in layers. After slurrying is completed, the operator releases the operating handle, and the auxiliary mechanism automatically lifts under the traction of the counterweight block. The operator then rinses the stirring shaft with clean water to prevent slurry from adhering.

[0014] Furthermore, the frame also includes a support block, a pair of positioning clamps are slidably disposed on the support block, each positioning clamp is provided with a V-shaped plate on its top, the two V-shaped plates fix the slurry container, a reset spring and a displacement detection element are provided between each positioning clamp and the support block, and the pulley reversing module is installed inside the support block, the pulley reversing module controls the symmetrical sliding of the pair of positioning clamps.

[0015] Furthermore, the pulley reversing module includes a pair of connecting rods, a riveting slider, a lower steel cable, several lower guide wheels, and a rack block. The riveting slider and the rack block are slidably installed in the support block. The pair of connecting rods are respectively rotated to the bottom of a pair of positioning clamps, and the other end of the pair of connecting rods is rotated to the riveting slider. The riveting slider and the rack block are connected in series on the lower steel cable. Several lower guide wheels are rotatably arranged in the support block, and the several lower guide wheels guide the lower steel cable.

[0016] Furthermore, the power module is mounted on a bracket. The power module includes a second drive unit, a gear, an arc-shaped toothed plate, and a lower handle. The middle part of the lower handle is connected to the second drive unit. The arc-shaped toothed plate is mounted on the bottom of the lower handle. The gear is rotatably mounted on the bracket. The upper part of the gear meshes with the arc-shaped toothed plate, and the lower part of the gear meshes with a rack block. When the operator places the slurry container, they first turn the lower handle or control the second drive unit to rotate the lower handle. The lower handle drives the gear to rotate through the arc-shaped toothed plate, and the gear drives the rack block to slide. The rack block drives the riveting through the lower steel cable. As the slider slides, the riveted slider pushes a pair of positioning clamps to slide and separate via two connecting rods. The pair of positioning clamps move symmetrically to ensure that the container is clamped and located directly below the stirring shaft. The slurry container is clamped by the pair of positioning clamps. Containers of different diameters cause the pair of positioning clamps to stop at different positions. The displacement detection element converts the position signal of the positioning clamps into the size signal of the container and feeds it back to the limiter for adjustment. The positioning mechanism can automatically clamp and detect the size of the container to ensure that the stirring shaft is always located in the center of the container. It adapts to slurry containers of different specifications, improving the equipment's versatility and mixing consistency.

[0017] Furthermore, existing pulping equipment lacks the capability to adjust the blade angle in real time during mixing to enhance turbulence, resulting in low mixing efficiency and easy slurry stratification. To solve the above problems, this invention provides the following technical solution: The pulping mechanism includes a power component and a mixing shaft. The mixing shaft is mounted on the power component, and a core rod is provided inside the mixing shaft. A grip sleeve is fitted on the outer side of the mixing shaft. Several sliding grooves are annularly opened at one end of the mixing shaft near the power component. Several sliders are connected to the core rod and slide in contact with the sliding grooves. An annular groove is opened in the inner ring of the grip sleeve, and several sliders also slide in contact with the annular groove. The core rod rotates simultaneously with the mixing shaft. Since the grip sleeve is fitted on the mixing shaft, the grip sleeve can be manually stopped when the mixing shaft rotates at high speed. The operator uses the grip sleeve to drive the moving core rod to slide up and down along the axial direction.

[0018] Furthermore, the pulping mechanism includes several sealing rotating blocks and a number of paddles equal to the number of sealing rotating blocks. The several sealing rotating blocks are rotatably connected to the stirring shaft. Each sealing rotating block is provided with teeth at the position where it contacts the core rod. The core rod is provided with grooves that mate with the teeth.

[0019] Several paddles are rotatably mounted on each sealing block. A fixed friction cone wheel is provided at the junction of the stirring shaft and each sealing block. The fixed friction cone wheel is located inside the sealing block. One end of each paddle is connected to a movable friction cone wheel, which is also located inside the sealing block and contacts the fixed friction cone wheel. The core rod uses the meshing of the grooves and teeth to drive all the sealing blocks to swing within a certain range. During the swinging process of the sealing blocks, the movable friction cone wheel is driven to roll along the surface of the fixed friction cone wheel. The movable friction cone wheel drives the paddle to change the angle. After the paddle and the stirring centrifugal plane form an angle, the different layers of slurry are mixed, effectively avoiding slurry stratification and enabling rapid stirring in localized areas. The linkage design between the grip sleeve and the core rod allows the operator to control the uniform swinging of all paddles in real time during the stirring process, changing the slurry flow direction and interlayer mixing effect, significantly improving the uniformity and efficiency of localized stirring.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Through auxiliary mechanisms and counterweight systems, the reverse torque during motor operation is effectively counteracted, significantly reducing the operator's load and improving operational comfort and stability. An adjustable limiter is used to automatically or manually set the swing range of the stirring shaft according to the container size, avoiding collisions between the paddle and the inner wall of the container, thus protecting the equipment and container while maximizing the stirring range.

[0022] 2. The linkage design between the grip sleeve and the core rod allows the operator to control all the paddles to swing uniformly in real time during the mixing process, changing the direction of slurry flow and the interlayer mixing effect, significantly improving the uniformity and efficiency of local mixing.

[0023] 3. The positioning mechanism can automatically clamp and detect the container size, ensuring that the mixing shaft is always in the center of the container. It can adapt to different specifications of slurry containers, improve the equipment's versatility and mixing consistency, and has a high degree of overall structure integration. It is easy to operate and has both automatic control and manual intervention functions, making it suitable for various cement and slurry mixing scenarios. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-8 As shown, the present invention provides a technical solution: a local slurry homogenization device for cement mixing, comprising a frame and a slurrying mechanism. The frame is equipped with a moving mechanism, a dual-axis balancing mechanism, and a positioning mechanism. The dual-axis balancing mechanism is mounted on the moving mechanism. The dual-axis balancing mechanism and the positioning mechanism are connected to the control system circuit. The dual-axis balancing mechanism includes a lifting platform 13 and an angle adjustment component. The lifting platform 13 is connected to the moving mechanism. The angle adjustment component is mounted on the lifting platform 13. The slurrying mechanism is mounted on the angle adjustment component. The positioning mechanism includes a pair of positioning clamps 3, a pulley reversing module, and a power module. The pulley reversing module is connected between the pair of positioning clamps 3 and the power module.

[0035] The frame also includes a support block 1, a pair of positioning clamps 3 slidably mounted on the support block 1, and a V-shaped plate on the top of each positioning clamp 3. The two V-shaped plates fix the slurry container. A reset spring and a displacement detection element (not shown in the figure) are provided between each positioning clamp 3 and the support block 1. A pulley reversing module is installed inside the support block 1. The pulley reversing module controls the symmetrical sliding of the pair of positioning clamps 3. The pulley reversing module includes a pair of connecting rods 4, a riveting slider 5, a lower steel cable 6, several lower guide wheels 7, and a rack block 8. The riveting slider 5 and the rack block 8 are slidably mounted in the support block 1. The pair of connecting rods 4 are respectively connected to the bottom of the pair of positioning clamps 3. The other end of the pair of connecting rods 4 is connected to the riveting slider 5. The riveting slider 5 and the rack block 8 are connected in series on the lower steel cable 6. Several lower guide wheels 7 are rotatably mounted in the support block 1 and guide the lower steel cable 6.

[0036] The power module is mounted on the bracket 2. The power module includes a second drive component, a gear 9, an arc-shaped toothed plate 10, and a lower handle 11. The second drive component is a servo motor 22. The middle part of the lower handle 11 is connected to the motor shaft of the servo motor 22. The arc-shaped toothed plate 10 is mounted on the bottom of the lower handle 11. The gear 9 is rotatably mounted on the bracket 2. The upper part of the gear 9 meshes with the arc-shaped toothed plate 10, and the lower part of the gear 9 meshes with the rack block 8. When the operator places the slurry container, they first move the lower handle 11, or control the servo motor 22 to drive the lower handle 11 to rotate. The lower handle 11 drives the gear 9 to rotate via the arc-shaped toothed plate 10, and the gear 9 drives the rack block 8 to slide. The rack block 8 drives the riveting slider 5 to slide via the lower steel cable 6. The riveting slider 5 pushes a pair of positioning clamps 3 to slide and separate via two connecting rods 4. The pair of positioning clamps 3 move symmetrically to ensure that the container is clamped and located directly below the stirring shaft 21. The slurry container is clamped by the pair of positioning clamps 3. Containers of different diameters cause the pair of positioning clamps 3 to stay in different positions. The displacement detection element converts the position signal of the positioning clamps 3 into the size signal of the container and feeds it back to the limiter for adjustment. The positioning mechanism can automatically clamp and detect the size of the container to ensure that the stirring shaft 21 is always located in the center of the container, adapting to different specifications of slurry containers and improving the equipment's versatility and mixing consistency.

[0037] The angle adjustment assembly includes an adapter frame 17, a machine base plate 18, and a pair of limiters. The pair of limiters are respectively installed in the lifting platform 13 and the adapter frame 17. The adapter frame 17 is rotatably mounted on the lifting platform 13, and the machine base plate 18 is rotatably mounted in the middle of the adapter frame 17. The rotation axis of the machine base plate 18 is perpendicular to the rotation axis of the adapter frame 17. The frame includes a support 2, and the moving mechanism includes at least a pair of guide posts 12, which are disposed on the support 2. The lifting platform 13 is slidably connected to the at least a pair of guide posts 12. Both the adapter frame 17 and the machine base plate 18 are provided with a protrusion 25. One limiter is located on the side of the lifting platform 13 near the protrusion 25 of the adapter frame 17, and the other limiter... Located on the side of the adapter frame 17 near the protrusion 25 of the machine base plate 18, the limiter in the lifting platform 13 includes a pair of notched annular blocks 24, a small bevel gear 23, and a first driving component, wherein the first driving component is also a servo motor 22. The pair of notched annular blocks 24 are connected to the lifting platform 13. The two sides of the pair of notched annular blocks 24 that are close to each other are provided with tooth grooves. The servo motor 22 is fixedly installed in the lifting platform 13. The small bevel gear 23 is connected to the motor shaft of the servo motor 22. The small bevel gear 23 is meshed with the tooth grooves of the pair of notched annular blocks 24. The pair of notched annular blocks 24 block the protrusion 25. The limiter in the adapter frame 17 has the same structure and installation method as the limiter in the lifting platform 13.

[0038] The lifting platform 13 slides up and down along the guide column 12. The limiter restricts the rotation range of the protrusion 25. The auxiliary mechanism supports the movement of the pulper. Therefore, the auxiliary mechanism and the frame bear the reverse torsional force generated by the power component during pulping. The power component is the main motor 19. The operator has less effort during pulping. The auxiliary mechanism effectively counteracts the reverse torsional force when the motor is running, greatly reducing the operator's load and improving operating comfort and stability. The size signal of the container drives the servo motors 22 in the two limiters to move simultaneously. The small bevel gear 23 drives a pair of notched annular blocks 24 to move in the opposite direction, so that the pair of notched annular blocks 24 simultaneously approach or move away from the protrusion 25. When the notched annular block 24 approaches the protrusion 25, the range of motion of the dual-axis balancing mechanism is reduced. When the notched annular block 24 moves away from the protrusion 25, the range of motion of the dual-axis balancing mechanism is increased. The limiter restricts the range of motion of the stirring shaft 21. When the operator is stirring, it effectively prevents the stirring shaft 21 from colliding with the inner wall of the container during high-speed stirring. On the one hand, it ensures that the stirring shaft 21 stirs in the container to the maximum extent, and on the other hand, it prevents the stirring shaft 21 from being damaged by the container. An adjustable limiter is used to automatically or manually set the swing range of the stirring shaft 21 according to the container size, so as to avoid the paddle 29 from colliding with the inner wall of the container, thus protecting the equipment and the container and ensuring the maximum stirring range.

[0039] The pulping mechanism includes a main motor 19 and a stirring shaft 21. The stirring shaft 21 is mounted on the main motor 19. A core rod 27 is installed inside the stirring shaft 21, and a grip sleeve 26 is fitted on the outer side of the stirring shaft 21. Several sliding grooves are formed around the end of the stirring shaft 21 near the main motor 19. Several sliders that slide in contact with the sliding grooves are connected to the core rod 27. An annular groove is formed on the inner ring of the grip sleeve 26, and several sliders also slide in contact with the annular groove. The pulping mechanism includes several sealing rotating blocks 28 and paddles 29 in the same number as the sealing rotating blocks 28. The sealing rotating blocks 28 are connected to the stirring shaft. 21. A sealed rotating connection is provided. Each sealing rotating block 28 is provided with teeth at the position where it contacts the core rod 27. The core rod 27 is provided with a tooth groove that matches the teeth. Several paddles 29 are rotatably mounted on each sealing rotating block 28. A fixed friction cone wheel 31 is provided at the junction of the stirring shaft 21 and each sealing rotating block 28. The fixed friction cone wheel 31 is located inside the sealing rotating block 28. One end of each paddle 29 is connected to a movable friction cone wheel 30. The movable friction cone wheel 30 is also located inside the sealing rotating block 28 and is in contact with the fixed friction cone wheel 31.

[0040] The core rod 27 rotates simultaneously with the stirring shaft 21. Since the grip sleeve 26 is fitted onto the stirring shaft 21, the grip sleeve 26 can be manually stopped when the stirring shaft 21 rotates at high speed. The operator uses the grip sleeve 26 to drive the moving core rod 27 to slide up and down along the axial direction. The core rod 27 uses the meshing of the tooth grooves and teeth to drive all the sealing rotating blocks 28 to swing within a certain range. During the swinging process, the sealing rotating blocks 28 drive the movable friction cone wheel 30 to roll along the surface of the fixed friction cone wheel 31. The movable friction cone wheel 30 drives the paddle plate 29 to change its angle. After the paddle plate 29 forms an angle with the stirring centrifugal plane, the different layers of slurry are mixed, effectively avoiding slurry stratification and enabling rapid stirring in local areas. The linkage design of the grip sleeve 26 and the core rod 27 allows the operator to control all the paddle plates 29 to swing uniformly in real time during the stirring process, changing the slurry flow direction and interlayer mixing effect, significantly improving the uniformity and efficiency of local stirring.

[0041] The moving mechanism also includes a counterweight module and an operating handle 20. The operating handle 20 is located at the bottom of the machine platform 18, and the counterweight module is mounted on the support 2. The counterweight module includes an upper steel cable 14, several upper guide rollers 15, and a counterweight block 16. One end of the upper steel cable 14 is connected to the lifting platform 13, and the other end of the upper steel cable 14 passes over all the upper guide rollers 15 and is connected to the counterweight block 16. The counterweight block 16 is slidably mounted on the side of the support 2, and the weight of the counterweight block 16 is slightly greater than the weight of the other end of the upper steel cable 14. The operator uses the operating handle 20 to... Press down the auxiliary mechanism and insert the stirring shaft 21 into the slurry container. Move the operating handle 20 up and down to make the stirring shaft 21 tumble the slurry in the container. Deflect the machine platform 18 by operating the handle 20 to make the stirring shaft 21 rotate and slurry in the container. The operator uses the other hand to drive the grip sleeve 26 to slide, so that the paddle 29 deflects repeatedly to slurry in layers. After slurrying is completed, the operator releases the operating handle 20, and the auxiliary mechanism is automatically lifted under the traction of the counterweight 16. The operator then rinses the stirring shaft 21 with clean water to prevent slurry from adhering.

[0042] The working principle of this invention is as follows: When the operator places the slurry container, he first pulls the lower handle 11 or controls the servo motor 22 to drive the lower handle 11 to rotate. The lower handle 11 drives the gear 9 to rotate through the arc-shaped toothed plate 10. The gear 9 drives the rack block 8 to slide. The rack block 8 drives the riveting slider 5 to slide through the lower steel cable 6. The riveting slider 5 pushes a pair of positioning clamps 3 to slide and separate through two connecting rods 4. The pair of positioning clamps 3 move symmetrically to ensure that the container is clamped and located directly below the stirring shaft 21. The slurry container is clamped by the pair of positioning clamps 3. Containers of different diameters cause the pair of positioning clamps 3 to stay in different positions. The displacement detection element converts the position signal of the positioning clamps 3 into the size signal of the container and feeds it back to the limiter for adjustment. The positioning mechanism can automatically clamp and detect the size of the container to ensure that the stirring shaft 21 is always located in the center of the container, adapting to different specifications of slurry containers and improving the equipment's versatility and mixing consistency.

[0043] The lifting platform 13 slides up and down along the guide column 12. The limiter restricts the rotation range of the protrusion 25. The auxiliary mechanism supports the movement of the pulper. Therefore, the auxiliary mechanism and the frame bear the reverse torsional force generated by the main motor 19 during pulping. The operator saves effort during pulping. The auxiliary mechanism effectively counteracts the reverse torsional force when the motor is running, greatly reducing the operator's load and improving operating comfort and stability. The size signal of the container drives the servo motors 22 in the two limiters to move simultaneously. The small bevel gear 23 drives a pair of notched annular blocks 24 to move in the opposite direction, so that the pair of notched annular blocks 24 simultaneously approach or move away from the protrusion 25. When 24 approaches 25, the range of motion of the dual-axis balancing mechanism is reduced. If the notched annular block 24 moves away from 25, the range of motion of the dual-axis balancing mechanism is increased. The limiter restricts the range of motion of the stirring shaft 21. When the operator is making pulp, it effectively prevents the stirring shaft 21 from colliding with the inner wall of the container during high-speed stirring. On the one hand, it ensures that the stirring shaft 21 stirs in the container to the maximum extent, and on the other hand, it prevents the stirring shaft 21 from being damaged by the container. An adjustable limiter is used to automatically or manually set the swing range of the stirring shaft 21 according to the container size, so as to avoid the paddle 29 from colliding with the inner wall of the container, thus protecting the equipment and the container and ensuring the maximum stirring range.

[0044] The core rod 27 rotates simultaneously with the stirring shaft 21. Since the grip sleeve 26 is fitted onto the stirring shaft 21, the grip sleeve 26 can be manually stopped when the stirring shaft 21 rotates at high speed. The operator uses the grip sleeve 26 to drive the moving core rod 27 to slide up and down along the axial direction. The core rod 27 uses the meshing of the tooth grooves and teeth to drive all the sealing rotating blocks 28 to swing within a certain range. During the swinging process, the sealing rotating blocks 28 drive the movable friction cone wheel 30 to roll along the surface of the fixed friction cone wheel 31. The movable friction cone wheel 30 drives the paddle plate 29 to change its angle. After the paddle plate 29 forms an angle with the stirring centrifugal plane, the different layers of slurry are mixed, effectively avoiding slurry stratification and enabling rapid stirring in local areas. The linkage design of the grip sleeve 26 and the core rod 27 allows the operator to control all the paddle plates 29 to swing uniformly in real time during the stirring process, changing the slurry flow direction and interlayer mixing effect, significantly improving the uniformity and efficiency of local stirring.

[0045] The weight of the counterweight 16 is slightly greater than the weight of the other end of the upper steel cable 14. The operator presses down the auxiliary mechanism through the operating handle 20, inserts the stirring shaft 21 into the slurry container, and moves the operating handle 20 up and down to make the stirring shaft 21 tumble the slurry in the container. The operator deflects the machine platform 18 through the operating handle 20 to make the stirring shaft 21 rotate and slurry in the container. The operator uses the other hand to drive the grip sleeve 26 to slide, so that the paddle 29 deflects repeatedly to slurry in layers. After slurrying is completed, the operator releases the operating handle 20, and the auxiliary mechanism is automatically lifted under the traction of the counterweight 16. The operator then rinses the stirring shaft 21 with clean water to prevent slurry from adhering.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
