Description

Technical Field

[0001] This utility model belongs to the field of cement mixing technology, specifically relating to a cement pole mixing device. Background Technology

[0002] The cement pole mixing and blending unit is used to prepare the concrete required for cement pole production. Its core principle is based on multi-dimensional mixing technology, achieving comprehensive, dead-angle-free mixing of materials. This unit not only improves the uniformity and stability of the concrete, preventing segregation, but also reduces dust emissions through optimized mixing processes, meeting environmental protection requirements. Widely used in the production of overhead power line supports in industries such as power, telecommunications, and railways, its efficient mixing capacity significantly shortens the production cycle and ensures the mechanical properties and durability of the cement poles. Some units also integrate intelligent control systems, supporting remote monitoring and fault warnings, further enhancing the automation level and operational reliability of the production line.

[0003] Chinese Patent Publication No. CN115446980B relates to the field of concrete mixing technology, specifically disclosing a cement pole mixing device. The device includes a cubic mixing tank with elastic diaphragms fixed around its perimeter, forming a closed cavity with the inner wall of the tank. A first one-way valve at the upper end of the cavity allows air to enter, and a second one-way valve at the lower end allows air to exit. A connecting rod is located at the center of the outer side of the elastic diaphragms, with a stop plate fixedly connected to the end of the connecting rod away from the diaphragm. A vertically distributed rotating shaft is installed at the center of the mixing tank, with cams fixedly connected around its center, all at the same horizontal plane as the stop plate. A spiral mixing paddle is located below the cams on the lower part of the rotating shaft. The cams compress or expand the cavity by pressing the elastic diaphragms, which can evenly mix coarse and fine sand and gravel, and also reduce the amount of ash being stirred up.

[0004] In actual use, this utility model can mix and stir cement. However, the existing cement pole mixing and stirring device generally has a simple stirring structure. It usually relies on a few single stirring shafts (8) to stir cement. This simple mechanical stirring method is difficult to achieve full mixing and stirring of cement in all directions and at a deep level. It will directly have an adverse effect on the production quality of cement poles, and may cause the poles to fail to reach the ideal state in key performance indicators such as strength and uniformity. As a result, the practicality of the cement pole mixing and stirring device is somewhat lacking. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a cement pole mixing device, comprising:

[0029] Mixing tank 1 and mounting cover 2;

[0030] Mounting ring 3 is located at the bottom of mounting cover 2. Mounting ring 3 has mounting plate 4 at its bottom and positioning plate 5 inside mounting ring 3 located above mounting plate 4.

[0031] Positioning sleeve 6 is set on the upper end of positioning plate 5. The upper end of positioning sleeve 6 passes through mounting cover 2 and extends to the outside. Mounting plate 4 is provided with drive shaft 7, and the upper end of drive shaft 7 passes through positioning sleeve 6.

[0032] Multiple mounting holes are provided through the mounting plate 4. Each mounting hole is provided with a matching stirring shaft 8. Each stirring shaft 8 is fitted with an external toothed ring 9. Each stirring shaft 8 is provided with multiple stirring blades 10, which are arranged in an alternating manner.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, the upper side of the mounting cover 2 is provided with a feed inlet 11, through which cement can be added into the mixing tank 1. The upper side of the mixing tank 1 is provided with a water inlet pipe 12, and the bottom of the mixing tank is provided with a discharge pipe 13.

[0034] Specifically, such as Figure 2 As shown, the inner wall of the mounting ring 3 has two snap-fit ​​grooves that are adapted to the mounting plate 4 and the positioning plate 5. The outer sides of the mounting plate 4 and the positioning plate 5 are respectively located in the two snap-fit ​​grooves and are slidably connected to the side walls of the two snap-fit ​​grooves. The two snap-fit ​​grooves in the mounting ring 3 can limit the position of the mounting plate 4 and the positioning plate 5 without affecting their rotation.

[0035] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the mounting ring 3 is provided with an inner toothed ring 14 that is adapted to the outer toothed ring 9. Multiple outer toothed rings 9 are meshed with the inner toothed ring 14. The upper ends of multiple stirring shafts 8 are all arranged in an arc shape. The bottom end of the positioning plate 5 is provided with multiple hemispherical contact blocks 15. The multiple contact blocks 15 are arranged in a ring around the central axis of the positioning sleeve 6.

[0036] Through its design, when the mounting plate 4 drives multiple mixing shafts 8 and multiple external toothed rings 9 to rotate, in conjunction with the internal toothed ring 14, the multiple mixing shafts 8 can rotate on their own axis while revolving around the central axis, which improves the mixing effect of the multiple mixing blades 10 on cement. At the same time, through the multiple abutment blocks 15 set at the bottom of the positioning plate 5, the multiple mixing shafts 8 can move downward intermittently under the action of the abutment blocks 15 when rotating, thereby increasing the mixing range that the multiple mixing blades 10 can mix and avoiding the problems of mixing dead zones and uneven mixing.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, the inner wall of the outer gear ring 9 is provided with multiple limiting plates 16, and the outer sides of the multiple stirring shafts 8 are all provided with limiting grooves that are adapted to the limiting plates 16. The multiple limiting plates 16 are respectively located in the multiple limiting grooves and are all provided with limiting springs 17. The upper ends of the multiple limiting springs 17 are respectively set at the upper ends of the multiple limiting grooves. The multiple limiting plates 16 in the outer gear ring 9, together with the limiting grooves on the outer side of the stirring shafts 8, can enable the outer gear ring 9 to drive the stirring shafts 8 to rotate without affecting the up and down movement of the stirring shafts 8. The multiple limiting springs 17 can enable the stirring shafts 8 to return to their original positions when they are separated from the contact block 15, thereby achieving the effect of its up and down reciprocating movement.

[0038] Specifically, such as Figure 2 and Figure 4 As shown, each of the multiple external gear rings 9 has a limiting ring 18 with an "L"-shaped cross-section at its bottom end. The upper end of the mounting plate 4 has multiple annular grooves that are adapted to the limiting rings 18. The multiple limiting rings 18 are located in the multiple annular grooves and are slidably connected to the side wall of the annular grooves. Through the limiting rings 18 with an "L"-shaped cross-section and the limiting grooves, the position of the external gear rings 9 can be limited without affecting their rotation, so that they can always mesh with the internal gear ring 14, ensuring the stability of their operation.

[0039] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, both the positioning sleeve 6 and the drive shaft 7 are provided with first bevel gears 19 on their outer sides. The two first bevel gears 19 are arranged in opposite directions. A drive motor 20 is provided on one side of the upper end of the mounting cover 2. The drive motor 20 is existing technology and will not be described in detail here. The output end of the drive motor 20 is provided with a second bevel gear 21 that is adapted to the first bevel gears 19. The two first bevel gears 19 are respectively meshed and connected to both sides of the second bevel gear 21. When the drive motor 20 is started, its output end will drive the second bevel gear 21 to rotate, which will drive the first bevel gears 19 on both sides to rotate in opposite directions. The two first bevel gears 19 will drive the positioning sleeve 6 and the drive shaft 7 to rotate respectively, which will enable the mounting plate 4 and the positioning plate 5 to rotate in opposite directions, making the mixing shaft 8 contact the contact block 15 more frequently and improving the mixing effect of cement.

[0040] Example 2:

[0041] Please see Figure 1-4 This utility model provides a cement pole mixing device, comprising:

[0042] Mixing tank 1 and mounting cover 2;

[0043] Mounting ring 3 is located at the bottom of mounting cover 2. Mounting ring 3 has mounting plate 4 at its bottom and positioning plate 5 inside mounting ring 3 located above mounting plate 4.

[0044] Positioning sleeve 6 is set on the upper end of positioning plate 5. The upper end of positioning sleeve 6 passes through mounting cover 2 and extends to the outside. Mounting plate 4 is provided with drive shaft 7, and the upper end of drive shaft 7 passes through positioning sleeve 6.

[0045] Multiple mounting holes are provided through the mounting plate 4. Each mounting hole is provided with a matching stirring shaft 8. Each stirring shaft 8 is fitted with an external toothed ring 9. Each stirring shaft 8 is provided with multiple stirring blades 10, which are arranged in an alternating manner.

[0046] Specifically, such as Figure 2 As shown, multiple stirring shafts 8 are provided with cleaning rods 22 on their outer sides that are adapted to the inner wall of the mixing tank 1, and one side of each cleaning rod 22 abuts against the inner wall of the mixing tank 1.

[0047] Its design allows multiple stirring shafts 8 to rotate simultaneously, which in turn drives multiple cleaning rods 22 to rotate, making it convenient and effective to clean the cement adhering to the inner wall of the mixing tank 1. This not only greatly saves manpower and time, but also accurately scrapes off the cement from the inner wall and integrates it into the mixing system, avoiding cement waste.

[0048] See Figure 1-4When using a cement pole mixing device to mix cement, cement is first added to the mixing tank 1 through the feed inlet 11, and then water is added to the mixing tank 1 through the water inlet pipe 12. During the mixing process, the drive motor 20 needs to be started. The output end of the drive motor 20 will drive the second bevel gear 21 to rotate. The second bevel gear 21 will simultaneously drive the two first bevel gears 19 to rotate in opposite directions. The two first bevel gears 19 will drive the positioning sleeve 6 and the drive shaft 7 to rotate respectively. The drive shaft 7 will drive the positioning disk 5 to rotate. When the mounting disk 4 rotates, it will drive multiple mixing shafts 8 to rotate. The multiple mixing shafts 8 will drive multiple mixing blades 10 to rotate. When the multiple mixing shafts 8 rotate, they will drive multiple external toothed rings 9 to rotate respectively. With the cooperation of the internal toothed ring 14 on the inner wall of the mounting ring 3, the multiple mixing shafts 8 can rotate on their own axis while revolving around the central axis, thereby improving the mixing effect of cement.

[0049] When the positioning sleeve 6 rotates, it drives the positioning disk 5 to rotate, which in turn drives multiple contact blocks 15 to rotate. This intermittently pushes multiple stirring shafts 8 up and down, increasing the mixing range of the multiple stirring shafts 8 and multiple stirring blades 10. This effectively avoids the problems of dead zones and uneven mixing. When the multiple stirring shafts 8 rotate, they drive multiple cleaning rods 22 to rotate, which can conveniently clean the cement adhering to the inner wall of the mixing tank 1. This not only greatly saves manpower and time, but also accurately scrapes the cement off the inner wall and integrates it into the mixing system, avoiding cement waste. This significantly improves the practicality of the cement pole mixing device in actual applications.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
