Technical Field
[0001] This invention relates to the field of mixing technology, specifically a manual mixer. Background Technology
[0002] A manual mixer is a machine that is manually driven to rotate a bladed shaft in a dosing cylinder or tank, rapidly mixing various raw materials to create a homogeneous powdery solid mixture, a liquid-solid two-phase mixture of suitable consistency, or a pure liquid mixture. Manual mixers are used in locations without electricity or internal combustion power, such as in hydraulic drilling, where solutions containing mud and sand need to be stirred to ensure more uniform mixing. Samples of the homogeneous solution are then taken to test the mud and sand content, thus accurately reflecting the mud and sand content in the drilling area. Therefore, the degree of mud and sand mixing directly reflects the accuracy of the test. However, existing manual mixers suffer from problems such as uneven mixing and inability to adapt to mixing tanks of different sizes. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a manual mixer to address the deficiencies of the prior art.
[0004] The objective of this invention is achieved through the following technical solution: A manual mixer includes a mixer frame for mounting on top of a mixing tank. An adjustable mixing assembly is mounted on the mixer frame, comprising a bearing sleeve and a mixing shaft. The bearing sleeve is rotatably mounted on the mixer frame, and the mixing shaft slides through the bearing sleeve, having a degree of freedom to move axially along the bearing sleeve. An adjustable blade assembly is mounted on the mixing shaft, comprising a blade lifting slider, a drive lever, blades, and a connecting rod. The drive lever is fixed to the bottom of the mixing shaft, and the blade lifting slider slides on the mixing shaft, moving axially along the mixing shaft. Multiple blades are arranged circumferentially along the mixing shaft. One end of each blade is hinged to the drive lever, and the other end is hinged to the connecting rod. The end of the connecting rod furthest from the blade is hinged to the blade lifting slider. The blade has an elliptical cross-section.
[0005] Furthermore, the adjustable stirring assembly also includes a shaft fixing plate and a pressure cap. The shaft fixing plate is hollow and its outer wall is fixed to the stirrer frame. A deep groove ball bearing and a tapered roller bearing are assembled inside the shaft fixing plate. The pressure cap is installed on the shaft fixing plate by screws to press the tapered roller bearing. The bearing sleeve is fitted to the inner ring of the deep groove ball bearing and the tapered roller bearing by a flat key.
[0006] Furthermore, the sidewall of the stirring shaft is provided with several threaded holes along its own axial direction, and the sidewall of the bearing sleeve is provided with a countersunk hexagon screw, the tail of which is inserted into the internal thread of the bearing sleeve to fit the threaded hole.
[0007] Furthermore, a handwheel is fixedly installed on the top of the stirring shaft.
[0008] Furthermore, the side wall of the stirring shaft is provided with several blade threaded holes along its own axial direction, and the side wall of the blade lifting slider is provided with blade internal hexagon countersunk screws, the tail thread of the blade internal hexagon countersunk screws being adapted to fit into one of the blade threaded holes.
[0009] Furthermore, the drive block has an upper slot at the position where the blade is set, one end of the blade is hinged to the upper slot via a hinge shaft, a U-shaped hinge block is fixed to the side wall of the blade, one end of the connecting rod is hinged to the U-shaped opening of the U-shaped hinge block via a hinge shaft, and a lower slot is opened at the position of the blade lifting slider corresponding to the position of the connecting rod, the other end of the connecting rod is hinged to the lower slot via a hinge shaft.
[0010] Furthermore, the blades are inclined at 30° to the rotating bearing of the stirring shaft.
[0011] Furthermore, the mixer frame includes a transverse frame and a longitudinal frame. The transverse frame and the longitudinal frame are connected in a cross shape. Both ends of the transverse frame are fixed with a recessed plate. A tightening screw is threaded through the recessed plate and is located below the transverse frame. Both ends of the longitudinal frame are provided with V-shaped clamping blocks, and the V-shaped clamping openings of the two V-shaped clamping blocks are arranged opposite each other.
[0012] Furthermore, both ends of the longitudinal frame are equipped with lead screws, the V-shaped clamping block is threaded onto the lead screws, and multiple fastening screws are threaded through the V-shaped clamping block.
[0013] The beneficial effects of this invention are: 1. Manual stirring is achieved by rotating the stirring shaft to drive the blades. Since the blades are arranged at an angle and have an elliptical cross-section, the blades exert a thrust on the solution in the direction of rotation and upward, which enhances the stirring intensity of the solution and achieves thorough mixing of mud and sand. This allows for accurate detection of the mud and sand content in the solution, thus accurately reflecting the mud and sand content in the drilling area.
[0014] 2. The stirring length of the stirring shaft and the coverage diameter of the blades in the mixing tank can be adjusted to adapt to the diameter and depth of the mixing tank, thereby making the mud and sand more uniform, facilitating the sampling of mud and sand, and thus accurately detecting the mud and sand content in the solution.

Detailed Implementation
[0016] Example 1 like Figures 1 to 5As shown, a manual mixer includes a mixer frame 1, which is mounted on top of a mixing tank. An adjustable mixing assembly is mounted on the mixer frame 1, comprising a bearing sleeve 2 and a mixing shaft 3. The bearing sleeve 2 is rotatably mounted on the mixer frame 1, and the mixing shaft 3 slides through the bearing sleeve 2, having a degree of freedom to move axially along the bearing sleeve 2. An adjustable blade assembly is mounted on the mixing shaft 3, comprising a blade lifting slider 4, a drive lever 7, blades 5, and a connecting rod 6. The drive lever 7 is fixed to the bottom of the mixing shaft 3, and the blade lifting slider 4 slides... The stirring shaft 3 is mounted on a moving part of the stirring frame 1. A blade lifting slider 4 moves axially along the stirring shaft 3. Multiple blades 5 are arranged circumferentially along the stirring shaft 3. One end of each blade 5 is hinged to a drive lever 7, and the other end is hinged to a connecting rod 6. The end of the connecting rod 6 away from the blade 5 is hinged to the blade lifting slider 4. The blades 5 have an elliptical cross-section. A handwheel 14 is fixedly mounted on the top of the stirring shaft 3. The stirring frame 1 is then mounted on a stirring tank containing the solution. The handwheel 14 is manually turned to rotate the stirring shaft 3 and bearing sleeve 2, causing the stirring shaft 3 to rotate the blades 5, thus stirring the solution. The mixing mechanism, under the action of connecting rod 6, causes blade 5 to tilt. Blade 5 has an elliptical cross-section and exerts a thrust on the solution in the direction of rotation and upwards, enhancing the mixing intensity and achieving thorough mixing of the mud and sand. This allows for accurate detection of the mud and sand content in the solution, thus accurately reflecting the mud and sand content in the drilling area. Since the size of the mixing tanks containing the solution varies, to achieve thorough mixing of the mud and sand, the coverage of blade 5 and the mixing depth of the mixing shaft 3 need to be adapted to the size of the mixing tank. Therefore, blade 5 is hinged, and the blade lifting slider 4 is adjusted... The axial position of the stirring shaft 3 causes the connecting rod 6 to drive the blades 5 to deflect around the hinge position with the drive lever 7, adjusting the coverage diameter of the blades 5 to fit the inner diameter of the mixing tank. Secondly, by moving the stirring shaft 3 up and down, the height of the stirring shaft 3 is adjusted, thereby adjusting the stirring depth of the blades 5, thus adapting to mixing tanks of different depths. In other words, both the stirring length of the stirring shaft 3 within the mixing tank and the coverage diameter of the blades 5 can be adjusted to suit the diameter and depth of the mixing tank, thereby enabling more uniform mixing of the sediment, facilitating sediment sampling, and accurately detecting the sediment content in the solution. Preferably, the blades 5 are inclined at 30° to the rotating bearing of the stirring shaft 3, which effectively propels the solution movement, increases the mixing effect, and makes the stirring more uniform.
[0017] Example 2 Based on Example 1, such as Figure 1As shown, the mixer frame 1 includes a transverse frame 17 and a longitudinal frame 18. The transverse frame 17 and the longitudinal frame 18 are connected in a cross shape. Both ends of the transverse frame 17 are fixed with recessed plates 22. A clamping screw 23 is threaded through the recessed plate 22 and is located below the transverse frame 17. Both ends of the longitudinal frame 18 are provided with V-shaped clamping blocks 24. The V-shaped clamping openings of the two V-shaped clamping blocks 24 are arranged opposite each other. Both ends of the longitudinal frame 18 are installed with lead screws 25. The V-shaped clamping blocks 24 are threaded onto the lead screws 25. Multiple fastening screws 26 are threaded through the V-shaped clamping blocks 24. First, adjust the position of the V-shaped clamping block 24 by adjusting the outer diameter of the mixing tank. Then, rotate the V-shaped clamping block 24 to make it rotate on the lead screw 25, thereby adjusting the distance between the two V-shaped clamping blocks 24. After roughly adjusting it, place the mixer frame 1 on top of the mixing tank. Then, rotate the fastening screw 26 and the clamping screw 23 to make the clamping screw 23 and the fastening screw 26 both abut against the outer wall of the mixing tank, forming a four-point clamp. This can adapt to the installation of mixing tanks of different sizes and has good installation strength, ensuring that it will not fall off during the mixing process.
[0018] Example 3 Based on Example 2, such as Figure 1 and Figure 2 As shown, the adjustable stirring assembly also includes a shaft fixing plate 8 and a pressure cap 9. The shaft fixing plate 8 is hollow, and its outer wall is fixed to the stirrer frame 1. A deep groove ball bearing 10 and a tapered roller bearing 11 are assembled inside the shaft fixing plate 8. The pressure cap 9 is installed on the shaft fixing plate 8 by screws to press the tapered roller bearing 11. The bearing sleeve 2 is fitted to the inner ring of the deep groove ball bearing 10 and the tapered roller bearing 11 by a flat key. The side wall of the stirring shaft 3 has several threaded holes 12 along its own axial direction. The side wall of the bearing sleeve 2 is provided with a countersunk head screw 13. The tail of the countersunk head screw 13 passes through the internal thread of the bearing sleeve 2 and is adapted to the threaded hole 12. The stirring shaft 3 is rotatably mounted on the shaft fixing plate 8 via bearings, while the stirring shaft 3 is fixedly mounted on the bearing sleeve 2 via hexagon countersunk screws 13. When the stirring shaft 3 rotates, it can drive the bearing sleeve 2 to rotate together, completing the stirring action. When it is necessary to adjust the stirring depth of the stirring shaft 3, the hexagon countersunk screws 13 are removed, allowing the stirring shaft 3 to slide within the bearing sleeve 2. Then, the stirring shaft 3 is slid to the corresponding position according to the depth of the stirring tank, and then the hexagon countersunk screws 13 are screwed into the corresponding threaded hole 12, thereby connecting the bearing sleeve 2 and the stirring shaft 3 together, realizing the adjustment of the stirring depth to adapt to the depth of the stirring tank.
[0019] Example 4 Based on Example 3, such as Figures 1 to 5As shown, the side wall of the stirring shaft 3 is provided with several blade threaded holes 15 along its own axial direction. The side wall of the blade lifting slider 4 is provided with blade internal hexagon countersunk screws 16. The tail thread of the blade internal hexagon countersunk screw 16 is adapted to fit into one of the blade threaded holes 15. By unscrewing the blade internal hexagon countersunk screw 16, the blade lifting slider 4 can be moved on the stirring shaft 3. The movement of the blade lifting slider 4 will drive the blade 5 to deflect through the connecting rod 6. Adjusting the included angle between the blade 5 and the connecting rod 6 will complete the rotation diameter of the blade 6 to adapt to the diameter of different mixing tanks, so that the mixer can adapt to the depth and diameter of the mixing tank, thereby improving the mixing effect.
[0020] Furthermore, the drive block 7 has an upper slot 19 at the position where the blade 5 is set. One end of the blade 5 is hinged to the upper slot 19 via a hinge shaft. A U-shaped hinge block 20 is fixed to the side wall of the blade 5. One end of the connecting rod 6 is hinged to the U-shaped opening of the U-shaped hinge block 20 via a hinge shaft. The blade lifting slider 4 has a lower slot 21 at the position corresponding to the connecting rod 6. The other end of the connecting rod 6 is hinged to the lower slot 21 via a hinge shaft. The deflection axis of the blade 5 is arranged horizontally and perpendicular to the blade 5. Similarly, the deflection bearing of the connecting rod 6 is arranged horizontally and perpendicular to the connecting rod 6, so that when the blade lifting slider 4 moves, the connecting rod 6 can adapt to the deflection to drive the blade 5 to deflect, adjust the diameter coverage area of the blade 5, and adapt to the inner diameter of the mixing tank.
