Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to a high-strength cement paste mixing device. Background Technology

[0002] High-strength cement typically refers to cement with a strength grade of C60 or higher. This type of cement achieves high values ​​in 28-day compressive strength tests, making it ideal for construction projects requiring heavy loads or high strength. High-strength cement is widely used in various construction projects demanding high strength, such as bridges, highways, and high-rise buildings. In these projects, high-strength cement provides stronger support and stability, ensuring the safety and durability of the structures.

[0003] Before high-strength cement can be used in large quantities, it needs to undergo standard tests for water content, setting time, and volume stability caused by free calcium oxide. Before these standard tests, cement paste needs to be prepared. According to current building materials industry standards, cement paste is prepared using low-speed mixing. After the cement paste preparation experimental device runs for 120 seconds, it is paused for 15 seconds. During this pause, the adhering substances on the mixing blades and container of the cement paste preparation experimental device need to be scraped off. Due to the short pause time, it is usually impossible to completely remove the adhering substances from the mixing blades. In addition, the mixer container must be cleaned after each measurement of cement standard consistency and setting time in the laboratory. Because high-strength cement has strong setting properties, manual cleaning is difficult to completely remove residues from the mixing pot and blades, which will affect the subsequent test results. The testing process is not only time-consuming and labor-intensive, but also inefficient. Furthermore, cement itself is corrosive, and prolonged direct contact with it can irritate the skin of operators, posing a health hazard. Utility Model Content

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 7As shown, this utility model discloses a high-strength cement paste mixing device, including a frame 100 and a mixing mechanism 300. The frame 100 is equipped with a lifting adjustment component 200, which includes a lifting plate 210 slidably connected to the frame 100 in the vertical direction. A mixing pot 400 is detachably mounted on the lifting plate 210. The mixing mechanism 300 includes a drive component 310, the output end of which has a quick connector 320 detachably connected to a mixing blade 330. The lower end of the mixing blade 330 can extend into the mixing pot 400. Specifically, in this embodiment, during the mixing test operation, the drive component 310 is activated, and power is transmitted from the drive component 310 to the quick connector 320 at the output end, causing the connected mixing blade 330 to rotate at high speed. The lower end of the mixing blade 330 extends into the mixing pot 400 to agitate the cement slurry inside. Through the continuous tumbling and shearing motion of the mixing blade 330, the components of the cement slurry are thoroughly mixed. After 120 seconds of agitation, a 15-second pause is taken. During this pause, the mixing blade 330 can be quickly detached from the quick-connect coupling 320, which allows for easy and quick removal of cement slurry and other contaminants from the blade. The removed contaminants are then placed back into the mixing pot to ensure the accuracy and effectiveness of subsequent mixing tests. After the mixing test, the mixing blade 330 is removed again using the detachable quick-connect coupling 320 and replaced with a component specifically designed for cleaning the mixing pot 400, such as a cleaning brush or steel brush 120. Then, the drive assembly 310 is activated to clean the interior of the mixing pot 400, removing any remaining cement slurry. The detachable connection between the quick connector 320 and the stirring blade 330 overcomes the limitations of traditional stirring devices where cleaning the stirring blade 330 is inconvenient. During brief pauses in the stirring test, the stirring blade 330 can be quickly disassembled for cleaning, eliminating the need to wait for the equipment to completely stop or perform complex disassembly operations, significantly saving time and improving work efficiency. Furthermore, timely cleaning of any adhering substances on the stirring blade 330 helps maintain its performance, reducing the possibility of adhering substances affecting the stirring effect and ensuring the accuracy and stability of each stirring test. After the stirring test, the stirring blade 330 can be easily replaced with other components to clean the mixing vessel 400. This design avoids the tediousness and difficulty of manually cleaning the mixing vessel 400 in traditional methods, improving the efficiency and quality of cleaning, ensuring the interior of the mixing vessel 400 is clean and tidy, fully preparing it for the next stirring test, and also helping to extend the service life of the mixing vessel 400.The aforementioned rapid cleaning methods for the mixing blades 330 and the mixing bowl 400 make the cleaning of the entire high-strength cement paste mixing unit more efficient and convenient. This reduces the increased maintenance costs and shortened service life caused by cleaning difficulties, improves the overall performance and reliability of the equipment, and provides strong support for the mixing tests and production of high-strength cement paste.

[0036] In some embodiments of this utility model, the quick connector 320 includes a sleeve 321 and a chuck 322. The upper end of the chuck 322 is fixedly connected to the output end of the drive assembly 310. The chuck 322 is threadedly connected to the sleeve 321 along the axial direction. The sleeve 321 is sleeved on the chuck 322. The lower end of the chuck 322 is provided with n jaws 3221, where n≥3. The lower end of the sleeve 321 is provided with a tapered guide portion 3211. The outer peripheral wall of the jaws 3221 abuts against the inner peripheral wall of the tapered guide portion 3211. When the chuck 322 moves along the axial direction, the tapered guide portion 3211 can control all the jaws 3221 to move closer or further apart. Specifically, in the initial state, the chuck 322 and the sleeve 321 are in a relative position, at which time the jaws 3221 are open to a large extent in their natural state. Since the chuck 322 is threadedly connected to the sleeve 321 along the axial direction, and the outer peripheral wall of the jaw 3221 abuts against the inner peripheral wall of the conical guide portion 3211, the position of the jaw 3221 is constrained by the sleeve 321 and the conical guide portion 3211. When installing the stirring blade 330 onto the quick connector 320, the connecting end of the stirring blade 330 is inserted into the middle position of the jaw 3221. Then, by rotating the sleeve 321, the sleeve 321 moves axially relative to the chuck 322. As the sleeve 321 moves upward along the axial direction, the conical guide portion 3211 of the sleeve 321 acts on the jaw 3221. Because the outer peripheral wall of the jaw 3221 abuts tightly against the inner peripheral wall of the conical guide portion 3211, the conical guide portion 3211 forces the jaws 3221 closer together, thereby tightly clamping the connecting end of the stirring blade 330, achieving a stable connection between the stirring blade 330 and the quick connector 320. In this embodiment, the grippers 3221 are made of elastic metal and can provide a certain degree of deformation. The grippers 3221 are evenly distributed in a conical shape at the lower end of the chuck 322, with gaps between adjacent grippers 3221. When it is necessary to disassemble the stirring blade 330, the sleeve 321 is rotated in the opposite direction, causing the sleeve 321 to move axially downward. At this time, the constraint effect of the conical guide portion 3211 of the sleeve 321 on the grippers 3221 changes. Under the guidance of its own elasticity and the conical guide portion 3211, the grippers 3221 move away from each other, releasing the clamping of the connecting end of the stirring blade 330, thereby easily removing the stirring blade 330 from the quick connector 320. Utilizing the threaded drive between the chuck 322 and the sleeve 321, as well as the conical guide structure, the operator can quickly install and remove the stirring blade 330 by simply rotating the sleeve 321. This quick connection and separation method greatly saves the equipment's assembly and disassembly time, improves work efficiency, and is especially suitable for work scenarios that require frequent replacement of the stirring blade 330.

[0037] In some embodiments of this utility model, the outer periphery of the sleeve 321 is provided with anti-slip texture 3212. The anti-slip texture 3212 on the outer periphery of the sleeve 321 can significantly increase the friction between the operator's hand and the surface of the sleeve 321. When the sleeve 321 is manually rotated, the anti-slip texture 3212 can prevent slippage between the hand and the sleeve 321, allowing the operator to apply force more stably and powerfully, easily rotate the sleeve 321, realize the relative axial movement between the chuck 322 and the sleeve 321, and thus smoothly complete the loading and unloading of the stirring blade 330.

[0038] In some embodiments of this utility model, a card holder 110 is provided on the frame 100, and a steel brush 120 is detachably mounted on the card holder 110. Specifically, in this embodiment, the card holder 110 is mounted on the frame 100, serving to support and position the steel brush 120. The card holder 110 and the steel brush 120 are detachably connected, and this connection can take various forms, such as snap-fit, magnetic connection, or simple plug-in connection. When the steel brush 120 is needed to clean the mixing pot 400, it can be easily removed from the card holder 110 and installed on the quick connector 320. After use, the steel brush 120 can be accurately placed back into the card holder 110 for the next use.

[0039] In some embodiments of this utility model, a cleaning mechanism 130 is also included. The cleaning mechanism 130 is provided with a cleaning pipe 131, one end of which is provided with a bamboo-joint tube segment 132, and the end of the bamboo-joint tube segment 132 is provided with a nozzle 133. Specifically, in this embodiment, when the cleaning mechanism 130 is working, water or cleaning fluid is transported through the cleaning pipe 131. The bamboo-joint tube segment 132 at one end of the cleaning pipe 131 has unique bendable and adjustable characteristics. The operator can flexibly adjust the shape and angle of the bamboo-joint tube segment 132 according to the part that needs to be cleaned, and aim the nozzle 133 at the mixing pot 400, the mixing blades 330, or other parts that need to be cleaned. Then, the water flows through the cleaning pipe 131 to the bamboo-joint tube segment 132, and finally sprays out from the nozzle 133 at the end, forming a water flow with a certain pressure and coverage area to rinse the target area and remove stains such as cement slurry adhering to it.

[0040] In some embodiments of this utility model, the drive assembly 310 includes a rotary motor 311, a reducer 312, and a planetary gear set 340. The output end of the rotary motor 311 is drivenly connected to the input end of the reducer 312; the output end of the reducer 312 is drivenly connected to the input end of the planetary gear set 340; and the output end of the planetary gear set 340 is drivenly connected to the stirring blade 330. In this embodiment, the coordinated operation of the reducer 312 and the planetary gear set 340 effectively increases the output torque. High-strength cement paste typically has high viscosity and resistance, requiring sufficiently high torque to ensure smooth stirring by the stirring blade 330. This drive assembly 310 provides strong torque, ensuring the stability and continuity of the stirring process and preventing the stirring blade 330 from stopping or jamming due to excessive resistance. The output end of the planetary gear set 340 is drivenly connected to the stirring blade 330 via a quick connector 320, allowing for quick assembly and disassembly of the stirring blade 330.

[0041] In some embodiments of this utility model, the planetary gear set 340 includes a central gear 341, a gear ring 342, planetary gears 343, a first gear shaft 344, and a second gear shaft 345. One end of the first gear shaft 344 is connected to the output end of the reducer 312, and the other end of the first gear shaft 344 is fixedly connected to the central gear 341. The gear ring 342 is fixedly connected to the frame 100, and the planetary gears 343 mesh with the inner circumferential walls of the central gear 341 and the gear ring 342, respectively. One end of the second gear shaft 345 is connected to the planetary gears 343, and the other end of the second gear shaft 345 is connected to the quick connector 320. Through this structural design, the stirring blades 330 can revolve and rotate, achieving efficient stirring.

[0042] In some embodiments of this utility model, the lifting adjustment assembly 200 includes a slide rail 220, which is fixedly connected to the frame 100; the lifting plate 210 is provided with a groove 211 that is slidably connected to the slide rail 220. In this embodiment, the slide rail 220 and the frame 100 are fixedly connected, providing stable support and a guiding foundation for the entire lifting adjustment. The groove 211 on the lifting plate 210 is slidably connected to the slide rail 220, allowing the lifting plate 210 to slide along the slide rail 220. The mixing pot 400 is detachably mounted on the lifting plate 210. When the height of the mixing pot 400 needs to be adjusted, the lifting plate 210 is pushed up and down along the direction of the slide rail 220, thereby changing the relative position of the mixing pot 400 and the stirring blade 330 to meet different working requirements, such as adjusting the distance between the mixing pot 400 and the stirring blade 330, or when disassembling or assembling the stirring blade 330. Through the design of this structure, the sliding connection between the slide groove 211 and the slide rail 220 enables the lifting plate 210 to achieve smooth movement during lifting. This smooth sliding reduces vibration and impact, which not only improves the stability of equipment operation but also extends the service life of the equipment.

[0043] In some embodiments of this utility model, the lifting adjustment assembly 200 includes a drive shaft 230, a first bevel gear 240, a second bevel gear 250, and a drive rod 260; the drive shaft 230 is rotatably connected to the frame 100; one end of the lifting plate 210 passes through the frame 100 and is threadedly connected to the drive shaft 230; the first bevel gear 240 and the drive shaft 230 are drive-connected; the first bevel gear 240 and the second bevel gear 250 mesh; the drive rod 260 and the second bevel gear 250 are drive-connected. Specifically, in this embodiment, when the height of the lifting plate 210 needs to be adjusted, the operator rotates the drive rod 260. The drive rod 260 is drive-connected to the second bevel gear 250, so the rotation of the drive rod 260 drives the second bevel gear 250 to rotate synchronously. The second bevel gear 250 meshes with the first bevel gear 240, and the rotation of the second bevel gear 250 causes the meshing first bevel gear 240 to rotate. The direction of power is changed through the meshing transmission of bevel gears, transmitting the circular motion of the drive rod 260 to the drive shaft 230, which is perpendicular to the drive rod 260. The first bevel gear 240 is connected to the drive shaft 230, and its rotation drives the drive shaft 230 to rotate. One end of the lifting plate 210 passes through the frame 100 and is threadedly connected to the drive shaft 230. When the drive shaft 230 rotates, due to the transmission action of the thread, the lifting plate 210 moves linearly along the axial direction of the drive shaft 230, thus raising or lowering the lifting plate 210 to adjust its height. The combination of the drive rod 260, bevel gears, and threaded transmission allows for precise control of the height of the lifting plate 210. Operators can finely adjust the position of the lifting plate 210 by slowly rotating the drive rod 260 to meet the precise height requirements in different working scenarios. For example, in some experiments or production processes with strict requirements for mixing depth, the distance between the mixing pot 400 and the mixing blades 330 can be accurately adjusted to ensure consistent mixing results.

[0044] In some embodiments of this utility model, an L-shaped handle 261 is provided at one end of the drive rod 260. The unique shape design of the L-shaped handle 261 greatly improves the ease of operation for the operator. Compared with ordinary straight handles, the horizontal part of the L-shaped handle 261 provides the operator with a larger space for force application and a greater point of leverage. When it is necessary to rotate the drive rod 260 to adjust the height of the lifting plate 210, the operator can naturally grasp the horizontal part of the L-shaped handle 261 and easily rotate the handle using the strength of their arm, without having to deliberately find a suitable grip point and direction of force as with ordinary handles, making the operation process smoother and more convenient.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
