Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a mixer with an adjustable stirring paddle. Background Art

[0002] A mixer is used to mix building materials such as cement, sand, and various dry mortars. It's a machine where a shaft with blades rotates in a cylinder or trough, stirring and mixing the various raw materials to form a mixture or a desired consistency. There are many types of mixers, including forced mixers, single-shaft mixers, and twin-shaft mixers.

[0003] The currently published patent: CN209333557U, discloses a stirring paddle for a mixer, including a connecting part, a first blade, a second blade and a connecting shaft. The first blade and the second blade are arranged at the radial ends of the outer wall of the connecting part. The side surface of the first blade is a twisted curved surface, and the second blade is bent along the length direction with an obtuse angle. In this way, the blade is asymmetric and can improve the stirring effect.

[0004] Based on the above search, it was found that the above patent has the following problems when used: the first blade and the second blade of the stirring paddle are arranged at the radial ends of the outer wall of the connecting part, so that the blades are asymmetric and can improve the stirring effect. However, the first blade and the second blade are fixedly arranged at the radial ends of the outer wall of the connecting part, and the staff cannot rotate and adjust the stirring blades. Due to the different shape characteristics of the stirring blades, they can be divided into flat-paddle agitators and inclined-paddle agitators. The flat-paddle agitator generates radial force, and the inclined-paddle agitator generates axial force. After the stirring blades are fixed, the staff cannot adjust the direction of the force generated by the agitator, so it cannot be adapted for stirring different materials. When the stirred materials are different, different stirring blades need to be replaced. Utility Model Content

[0025] See also Figure 1-5 The utility model provides a technical solution: a mixer with adjustable stirring paddles, including a stirring tank 1 and a blade adjustment device, a discharge pipe 2 is fixedly connected to the bottom of the stirring tank 1, a stirring shaft 3 is rotatably connected to the inside of the stirring tank 1, a stirring motor 4 is fixedly installed at the bottom of the stirring tank 1, and the lower end of the stirring shaft 3 is fixedly connected to the output end of the stirring motor 4. The blade adjustment device includes three rotating shafts 5, three stirring blades 6, three first bevel gears 7, an adjusting rod 8, a second bevel gear 9, a fixed block 10, a cylindrical clamping block 11, a protrusion 12 and a spring 13. The three rotating shafts 5 are all rotatably installed inside the stirring shaft 3, and the three stirring blades 6 are respectively slidably installed on the surface of the three rotating shafts 5. The three first bevel gears 7 are respectively The second bevel gear 9 is fixedly connected to the surface of the three rotating shafts 5, and the adjusting rod 8 is rotatably connected to the inside of the stirring shaft 3. The second bevel gear 9 is fixedly connected to the lower end of the adjusting rod 8, and the second bevel gear 9 is meshed with the three first bevel gears 7. The upper end of the adjusting rod 8 extends to the outside of the stirring shaft 3. The fixed block 10 is fixedly connected to the upper end of the adjusting rod 8, and the cylindrical block 11 is slidably connected to the inside of the fixed block 10. The protrusion 12 is fixedly connected to the surface of the cylindrical block 11, and the spring 13 is fixedly connected to the upper end of the cylindrical block 11. One end of the spring 13 away from the cylindrical block 11 is fixedly connected to the inner wall of the fixed block 10. The upper end of the stirring shaft 3 is provided with two circular card holes 14, and the lower end of the cylindrical card block 11 is slidably connected to the inside of the circular card hole 14.

[0026] The staff puts the material into the mixing tank 1 and starts the mixing motor 4. The output end of the mixing motor 4 rotates to drive the mixing shaft 3 to rotate. The rotation of the mixing shaft 3 can drive the three mixing blades 6 to rotate and mix the materials through the three rotating shafts 5. When the staff needs to adjust the mixing blades 6 to the flat paddle type, the staff first slides the cylindrical block 11 upward through the convex block 12 and squeezes the spring 13. The spring 13 gives the cylindrical block 11 a downward elastic force. The cylindrical block 11 slides upward and slides out of the circular card hole 14, thereby releasing the fixing effect on the adjusting rod 8. Then, the staff can rotate the adjusting rod 8 through the fixing block 10. The rotation of the adjusting rod 8 drives the second bevel gear 9 to rotate, and the second bevel gear 9 rotates The rotation can drive the three first bevel gears 7 to rotate simultaneously. The rotation of the three first bevel gears 7 can drive the three rotating shafts 5 to rotate simultaneously. The rotation of the three rotating shafts 5 drives the three stirring blades 6 to rotate simultaneously to a horizontal state. After the staff loosens it, the spring 13 pushes the cylindrical block 11 to slide downward and get into another circular card hole 14 to fix the adjusting rod 8 again, and then fix the three stirring blades 6 again. By setting the stirring blade 6 in an adjustable manner, the staff can adjust the direction of the force generated by the stirring blade 6, so that it can be adapted to different materials for stirring. When the stirred materials are different, there is no need to replace different stirring blades 6, which is convenient for the staff to use three stirring blades 6 to stir materials of different specifications.

[0027] The insides of the three stirring blades 6 are all threadedly connected with bolts 15 , and the surfaces of the three rotating shafts 5 are all provided with through holes 16 , and the bolts 15 are slidably engaged in the insides of the through holes 16 .

[0028] When the mixer is in use, the stirring blade 6 is mainly used to rotate and stir the material. The stirring blade 6 is easy to be damaged. When the stirring blade 6 is damaged and needs to be replaced, the staff rotates the bolt 15 with a wrench. The bolt 15 rotates and slides and disengages from the inside of the through hole 16 through the threaded connection between the stirring blade 6, thereby releasing the fixing effect on the stirring blade 6. Then the staff slides the stirring blade 6 and disengages it from the surface of the rotating shaft 5 to complete the disassembly, thereby improving the convenience of disassembly and installation of the stirring blade 6.

[0029] Working principle: The mixer has an adjustable stirring paddle. The staff starts the stirring motor 4. The output end of the stirring motor 4 rotates to drive the stirring shaft 3 to rotate. The stirring shaft 3 rotates to drive the three stirring blades 6 to rotate and mix the materials through the three rotating shafts 5. The staff first slides the cylindrical block 11 upward through the convex block 12 and squeezes the spring 13. The cylindrical block 11 slides upward and slides out of the circular card hole 14. The staff can rotate the adjusting rod 8 through the fixed block 10. The rotation of the adjusting rod 8 drives the second bevel gear 9 to rotate. The rotation of the second bevel gear 9 can drive the three first bevel gears 7 to rotate at the same time. The three first bevel gears 7 rotate at the same time. The rotation of a bevel gear 7 can drive the three rotating shafts 5 to rotate at the same time. The rotation of the three rotating shafts 5 drives the three stirring blades 6 to rotate at the same time to a horizontal state. After the staff loosens it, the spring 13 pushes the cylindrical block 11 to slide downward and get into another circular card hole 14 to fix the three stirring blades 6 again. The staff can adjust the direction of the force generated by the stirring blade 6. The staff rotates the bolt 15 with a wrench. The bolt 15 rotates to slide and disengage from the inside of the through hole 16 through the threaded connection between the stirring blade 6. Then the staff slides the stirring blade 6 and disengages it from the surface of the rotating shaft 5 to complete the disassembly.
