Description

Technical Field

[0001] This utility model relates to the technical field of mixing equipment accessories, and in particular to a mixing component for a cement paste mixing device. Background Technology

[0002] The mixing assembly is an important component of a cement paste mixing device. The mixing assembly consists of a drive unit, a mixing frame, and a mixing pot. When in use, the drive unit drives the mixing frame to mix the cement and water in the mixing pot. The mixing frame is an important component for the cement paste device to uniformly mix cement and water. In existing technology, the mixing frame is usually modified to facilitate maintenance.

[0003] For example, in the patent published under publication number CN221641315U entitled "Quick-release type mixing shaft for cement paste mixer", when using it, first remove the screw, then unscrew the locking head from the bottom of the intermediate shaft, and multiple mixing components can be disassembled from the bottom of the intermediate shaft. Finally, the intermediate shaft can be directly disassembled from the bottom of the connecting shaft to complete the disassembly of the entire mixing shaft. The operation process is simple, simplifies the disassembly steps of the mixing shaft, and facilitates its use in the mixer.

[0004] However, it still has some shortcomings. When in use, the power is transmitted step by step through the first rod → the insertion hole → the second rod. However, the first and second rods have small diameters and are fixed by welding. Therefore, when rotating at high speed or when the material resistance changes suddenly, the first and second rods may bend or even break. In this case, the reliability of the stirring component during rotation cannot be guaranteed, and the service life of the stirring component cannot be guaranteed either. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a stirring component that can be easily disassembled while ensuring service life.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a mixing component for a cement paste mixing device, comprising: a mounting column, the mounting column being a polygonal column body, a limiting seat being provided at the bottom of the mounting column, and a stud being provided at the top of the mounting column, the size of the stud being smaller than the size of the mounting column; a connecting seat, wherein multiple connecting seats are provided, each connecting seat having a polygonal first connecting hole matching the mounting column, each connecting seat being sleeved with the mounting column through the first connecting hole, the size of the first connecting hole being smaller than the size of the limiting seat, and a mixing rod being provided on the sidewalls at both ends of the connecting seat; a scraper, wherein at least two scrapers are provided, each scraper being installed at the end of the mixing rod away from the connecting seat, the scraper being detachably connected to the mixing rod; a first connecting sleeve, wherein the first connecting sleeve is installed on the top of the mounting column, the first connecting sleeve having a first threaded hole for screwing into the stud, an elastic clamping ring being provided at the bottom of the first connecting sleeve, and a connecting shaft being provided at the top of the first connecting sleeve.

[0007] A further preferred embodiment of this utility model is: a spacer is provided between each of the connecting seats, and a second connecting hole of the same size as the first connecting hole is provided on each of the spacers.

[0008] A further preferred embodiment of this utility model is as follows: a plurality of second connecting sleeves are evenly arranged on the scraper and aligned with the stirring rod. The second connecting sleeves are inserted into the stirring rod. Each second connecting sleeve has a first through hole penetrating through it. The stirring rod has a second through hole penetrating through it. A limiting rod is arranged in the first through hole and the second through hole. A limiting block is arranged at the top of the limiting rod, and a limiting sleeve is screwed to the bottom of the limiting rod.

[0009] A further preferred embodiment of this utility model is that the top of each stirring rod is provided with not less than two stirring blocks.

[0010] A further preferred embodiment of this utility model is as follows: the scraper has a plurality of second screw holes evenly provided on the side wall near the stirring rod, and the second connecting sleeve is detachably connected to the scraper through the second screw holes.

[0011] A further preferred embodiment of this utility model is as follows: each stirring block includes a bolt screwed to a stirring rod, a connecting rod is provided at the top of the bolt, and a block is provided at the top of the connecting rod.

[0012] A further preferred embodiment of this utility model is that the bolt is integrally formed with the connecting rod and the block.

[0013] Compared with the prior art, the advantage of this utility model is that, by setting the stirring assembly so that multiple connecting seats, along with the stirring rod installed on the side wall of the connecting seat, are sequentially installed onto the mounting column through the first connecting hole until the top of the connecting seat is flush with the top of the mounting column, and then the first connecting sleeve is screwed onto the stud through the first screw hole (wherein the direction in which the first connecting sleeve is screwed into the stud is opposite to the direction of rotation of the output end of the drive device, so as to prevent the first connecting sleeve from disengaging from the stud when the drive device is working), until the bottom of the first connecting sleeve abuts and presses against the top of the connecting seat. This ensures that the connecting seat is securely installed. The stability of the assembly when mounted on the column is ensured by the elastic clamping ring, which improves the clamping effect of the first connecting sleeve on the connecting seat. When disassembling the mixing assembly, the first connecting sleeve is first removed from the stud, and then the connecting seat is removed from the mounting column in sequence. This facilitates the assembly and disassembly of the mixing assembly. Because the mounting column is polygonal and the first connecting hole on the connecting seat is also polygonal, the mounting column can drive the connecting seat and the mixing rod mounted on the connecting seat to rotate when the mixing assembly rotates. This ensures the reliability of the mixing assembly during rotation and also guarantees the service life of the mixing assembly. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] This embodiment mainly describes the structure of a mixing component for a cement paste mixing device, as detailed below: like Figures 1-8As shown, a mixing assembly for a cement paste mixing device includes a polygonal mounting column 10. A stud 11 and a limiting seat 1 are respectively provided at the top and bottom of the mounting column 10, with the stud 11 being smaller than the mounting column 10. Multiple connecting seats 2 are axially arranged on the mounting column 10, and each connecting seat 2 has a polygonal first connecting hole 21 that matches the mounting column 10. The connecting seats 2 are connected to the mounting column 10 through the first connecting hole 21. To prevent the connecting seats 2 from detaching from the bottom of the mounting column 10, the size of the first connecting hole 21 on the connecting seat 2 is smaller than the size of the limiting seat 1, thus limiting the connecting seat 1. A mixing rod is provided on the sidewalls at both ends of each connecting seat 2. 3. At the same time, a scraper 6 is provided at the end of the mixing rod 3 away from the connecting seat 2. In this way, when the mixing assembly rotates, the scraper 6 can scrape the inner wall of the mixing tank (the container used to hold cement and water in the cement paste mixing device), thereby reducing the cement adhering to the inner wall of the mixing tank. In order to facilitate the disassembly and assembly of the scraper 6, the scraper 6 is detachably connected to the mixing rod 3. Finally, a first connecting sleeve 9 is provided at the top of the mounting column 10, and a first screw hole 93 for screwing into the stud 11 is opened in the first connecting sleeve 9. Then, a connecting shaft 92 connected to the output end of the drive device is provided at the top of the first connecting sleeve 9. At the same time, in order to improve the pressing effect of the first connecting sleeve 9 on the connecting seat 2, an elastic pressing ring 91 made of elastic rubber is provided at the bottom of the first connecting sleeve 9. Therefore, when assembling the mixing assembly, firstly, multiple connecting seats 2, along with the mixing rods 3 mounted on the side walls of the connecting seats 2, are sequentially installed onto the mounting column 10 through the first connecting holes 21 until the top of the connecting seats 2 is flush with the top of the mounting column 10. Then, the first connecting sleeve 9 is screwed onto the stud 11 through the first screw hole 93 (wherein the direction in which the first connecting sleeve 9 is screwed into the stud 11 is opposite to the direction of rotation of the output end of the drive device, thus preventing the first connecting sleeve 9 from detaching from the stud 11 during operation). This continues until the bottom of the first connecting sleeve 9 abuts and presses against the top of the connecting seat 2. This ensures the stability of the connecting seat 2 on the mounting column 10, while the elastic clamping ring 91 is designed... The placement can improve the clamping effect of the first connecting sleeve 9 on the connecting seat 2. Then, the scraper 6 is installed on the stirring rod 3. When disassembling the stirring assembly, first remove the scraper 6 from the stirring rod 3, then remove the first connecting sleeve 9 from the stud 11, and then remove the connecting seat 2 from the mounting post 10 in sequence. This facilitates the disassembly and assembly of the stirring assembly. Since the mounting post 10 is polygonal and the first connecting hole 21 on the connecting seat 2 is also polygonal, when the stirring assembly rotates, the mounting post 10 can drive the connecting seat 2 and the stirring rod 3 installed on the connecting seat 2 to rotate. This ensures the reliability of the stirring assembly when it rotates and also ensures the service life of the stirring assembly.

[0020] Furthermore, to facilitate the adjustment of the number of connecting seats 2 on the mounting column 10 when using the mixing assembly (for example, when mixing cement mixtures with high viscosity, if there are too many mixing rods 3 in the mixing assembly, it will increase the load on the drive device, thus increasing the energy consumption of the drive device), a spacer 8 is fitted on each mounting column 10 between the connecting seats 2, and a second connecting hole 81 with the same size as the first connecting hole 21 is opened on each spacer 8. Thus, when reducing the number of connecting seats 2 on the mounting column 10, the mixing assembly is first disassembled and then reassembled. For example, when assembling the mixing assembly, first install one connecting seat 2 on the mounting column 10, and then install one spacer 8 on the mounting column 10. Repeat this process several times until the top of the spacer 8 is flush with the top of the mounting column 10. Finally, the first connecting sleeve 9 is installed on the stud 11. In this way, as the number of connecting seats 2 on the mounting column 10 decreases, the weight of the mixing assembly can be reduced, and the mixing assembly can also be used to mix cement mixtures with low viscosity, thus improving the application range of the mixing assembly.

[0021] Furthermore, to facilitate the disassembly and assembly of the scraper 6, multiple second connecting sleeves 5 are evenly arranged on the scraper 6, aligned with the stirring rod 3. The second connecting sleeves 5 are inserted into the stirring rod 3. To ensure the reliability of the connection between the connecting sleeve and the stirring rod 3, a first through hole 51 is opened on each of the second connecting sleeves 5. At the same time, a second through hole 32 is opened on each of the stirring rods 3. Thus, when the stirring rod 3 is inserted into the second connecting sleeve 5, the first through hole 51 and the second through hole 32 are aligned. Finally, a limiting rod 7 is inserted into the first through hole 51 and the second through hole 32. In order to prevent the limiting rod 7 from dislodging from the first through hole 51 and the second through hole 32, a limiting block 71 is provided at the top of the limiting rod 7, and a limiting sleeve 72 is screwed to the bottom of the limiting rod 7.

[0022] Furthermore, in order to facilitate the disassembly and assembly of the second connecting sleeve 5, a plurality of second screw holes 61 are evenly provided on the side wall of the scraper 6 near the stirring rod 3, and the second connecting sleeve 5 is detachably connected to the scraper 6 through the second screw holes 61.

[0023] In order to improve the mixing effect of the stirring rod 3, at least two stirring blocks 4 are provided on the top of the stirring rod 3.

[0024] Furthermore, in order to facilitate the maintenance of the mixing block 4, each mixing block 4 includes a bolt 41 and a third screw hole 31 for screwing into the top of the mixing rod 3. Then, a connecting rod 42 is provided on the top of the bolt 41, and a block 43 is provided on the top of the connecting rod 42.

[0025] Furthermore, to ensure the strength of the mixing block 4, the bolt 41 is integrally formed with the connecting rod 42 and the block 43.
