Description

Technical Field

[0001] This application relates to the field of mixer technology, and in particular to a multifunctional cement paste mixer. Background Technology

[0002] A cement paste mixer is used to mix cement and water according to standard specifications to form a uniform experimental paste. It is used to determine the standard consistency and setting time of cement and to make stability test blocks. It is an essential and indispensable piece of equipment for cement plants, construction companies, relevant professional colleges and research institutions' cement laboratories.

[0003] A cement paste mixer typically includes a body on which mixing blades, transmission components, and a lifting platform are installed. A mixing bowl is mounted on the platform. The conventional installation method is that the platform has an installation groove, and the bottom of the mixing bowl has an installation column that plugs into the installation groove. The installation column is directly inserted into the installation groove to connect the mixing bowl and the platform.

[0004] However, in the actual mixing process, as the cement paste becomes more and more viscous with the stirring action, the viscous cement paste easily drives the mixing pot to rotate, and the relative motion trajectory between the mixing pot and the mixing blades is disrupted. At this time, the mixing effect of the mixing blades on the cement paste becomes worse, and there is a significant deficiency. Utility Model Content

[0005] To improve the mixing effect of cement paste, this application provides a multifunctional cement paste mixer.

[0006] The multifunctional cement paste mixer provided in this application adopts the following technical solution:

[0007] A multifunctional cement paste mixer includes a body, on which a mixing assembly, a tray, and a mixing pot are mounted. The tray has an installation groove, and the bottom surface of the mixing pot has an installation column that engages with the installation groove. A fastening assembly is installed within the installation column, including a connecting plate. The tray and the installation column have sliding grooves that slidably engage with the connecting plate, the sliding grooves being parallel to the radial direction of the installation column. The connecting plate has a cavity, and fastening plates are slidably connected to opposite sides of the cavity. Openings communicating with the cavity are formed on the outer surfaces of the connecting plate and the installation column. Fastening grooves that engage with the fastening plates are formed on the inner sidewall of the installation groove. An operating component is provided on the connecting plate to drive the fastening plates into the fastening grooves.

[0008] By adopting the above technical solution, when installing the mixing pot, the mounting column is first inserted into the mounting groove, and then the plug-in plate is aligned with the sliding groove on the support plate and inserted. After the plug-in plate is inserted into the sliding groove of the mounting column, the worker drives the two fastening plates to move synchronously toward the opening and insert them into the fastening groove through the operating component. With the plug-in cooperation of the fastening plates and the fastening groove, the relative rotation between the mounting column and the mounting groove is restricted, thereby effectively reducing the possibility of the mixing pot rotating during the mixing process, ensuring that the mixing blades fully mix the cement paste according to the predetermined trajectory, and improving the mixing effect of the cement paste.

[0009] Optionally, the operating component includes an operating rod rotatably connected within the plug-in plate, a gear coaxially mounted on the operating rod, the gear rotatably mounted within the cavity, and a rack plate meshing with the gear, corresponding one-to-one with the two fastening plates, the rack plate being mounted on the corresponding fastening plate.

[0010] By adopting the above technical solution, the worker rotates the operating lever, which drives the gear to rotate synchronously in the forward or reverse direction. The gear drives the two meshing rack plates to move in a direction away from or close to each other. The movement of the gear drives the two fastening plates to slide in the cavity and synchronously insert or disengage from the fastening groove, thereby realizing the fixing and disassembly of the plug-in plate. This setting realizes the synchronous movement of the two plug-in plates and improves the convenience of worker operation.

[0011] Optionally, a limiting groove is provided on the inner sidewalls opposite to the cavity, and a limiting block is provided on the fastening plate to slide in the limiting groove. When the limiting block moves to the end of the limiting groove near the fastening groove, the fastening plate is fully inserted into the fastening groove. When the limiting block moves to the other end of the limiting groove, the end face of the fastening plate is flush with the outer end face of the plug-in plate.

[0012] By adopting the above technical solution, the sliding fit between the limiting groove and the limiting block provides guidance and limit for the sliding of the fastening plate, reducing the possibility of the fastening plate deviating or getting stuck in the cavity, thereby ensuring that the fastening plate can be smoothly inserted into the fastening groove or retracted to the initial position. At the same time, the limiting groove restricts the working stroke of the fastening plate, preventing the fastening plate from detaching from the plug-in plate due to excessive rotation of the operating lever by the worker, thus improving the stability of the mixing pot installation and disassembly process.

[0013] Optionally, the end of the operating lever extends to the outer surface of the plug-in plate and is coaxially provided with a handwheel.

[0014] By adopting the above technical solution, the handwheel allows workers to complete the fixing operation on the outer surface of the plug plate, further improving the convenience of workers during installation and disassembly.

[0015] Optionally, the plug-in plate is provided with a locking component, which is used to restrict the rotational movement of the operating lever.

[0016] By adopting the above technical solution, after the fastening plate is inserted into the fastening groove, the worker restricts the rotation of the operating rod by locking the component, thereby locking the position of the rack plate and ensuring that the fastening plate is tightly inserted into the fastening groove. The setting of the locking component effectively reduces the possibility of the fastening plate coming out of the fastening groove due to the worker accidentally touching the operating rod or mechanical vibration, ensuring that the mixing pot is always in a stable connection state and improving the stability of the mixing process.

[0017] Optionally, the operating lever has a limiting groove along its axial direction. The locking assembly includes a locking block slidably connected to the limiting groove. The locking block is sleeved on the outer surface of the operating lever and has a square cross-section. The insertion plate has a circular groove that rotatably engages with the locking block. The inner sidewall of the circular groove has a square groove that engages with the locking block. A locking bolt is threaded onto the insertion plate. The end of the locking bolt extends into the circular groove. When the fastening plate is inserted into the fastening groove, the locking bolt pushes the locking block into the square groove. A return spring is provided in the limiting groove. In its natural state, the locking block is positioned inside the circular groove.

[0018] By adopting the above technical solution, after the fastening plate is inserted into the fastening groove, the worker tightens the locking bolt. The locking bolt overcomes the elastic force of the return spring and pushes the locking block into the square groove. Since the locking block is slidably sleeved on the outer surface of the operating rod through the limiting groove, the rotation of the operating rod is restricted after the locking block and the square groove are engaged, thereby realizing the locking function. When it is necessary to disassemble the mixing pot, the locking bolt is loosened. Under the action of the return spring, the locking block is disengaged from the square groove and moves along the limiting groove into the round groove. At this time, the rotation restriction of the locking block and the operating rod is released. The worker rotates the operating rod to make the fastening plate disengage from the fastening groove, thereby realizing disassembly.

[0019] Optionally, the outer surface of the mounting column is provided with a positioning strip, and the inner sidewall of the mounting groove is provided with a positioning groove that slides with the positioning strip. When the positioning strip is inserted into the positioning groove, the sliding grooves on the support plate and the mounting column are directly connected.

[0020] By adopting the above technical solution, workers can ensure that the sliding grooves on the support plate and the mounting column are aligned and connected through the sliding cooperation of the positioning strip and the positioning groove, thereby ensuring that the plug plate can slide smoothly in the sliding groove. This effectively avoids the problem of fastening components not working properly due to installation deviation, reduces the adjustment time during the installation process, and improves installation efficiency.

[0021] Optionally, the machine body is provided with a protective shell, and a protective door is hinged to the protective shell, with the protective door covering the outer periphery of the mixing pot.

[0022] By adopting the above technical solutions, the protective shell and protective door effectively block the splashing path of cement slurry, reduce the pollution of laboratory countertops, floors and other equipment caused by cement slurry splashing, and reduce cleaning and maintenance costs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application sets up a fastening component and an operating component. The operating component drives two fastening plates to move synchronously toward the opening and insert into the fastening groove. With the insertion and cooperation of the fastening plates and the fastening groove, the relative rotation between the mounting column and the mounting groove is restricted, thereby effectively reducing the possibility of the mixing pot rotating during the mixing process. This ensures that the mixing blades fully mix the cement paste according to the predetermined trajectory, thereby improving the mixing effect of the cement paste.

[0025] 2. By setting a locking component, after the fastening plate is inserted into the fastening groove, the worker can restrict the rotation of the operating rod by using the locking component, thereby locking the position of the rack plate and ensuring that the fastening plate is tightly inserted into the fastening groove. The setting of the locking component effectively reduces the possibility of the fastening plate coming out of the fastening groove due to the worker accidentally touching the operating rod or mechanical vibration, ensuring that the mixing pot is always in a stable connection state and improving the stability of the mixing process.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a multifunctional cement paste mixer.

[0033] Reference Figure 1 and Figure 2 A multifunctional cement paste mixer includes a body 1, on which a mixing assembly 101 and a pallet 102 are mounted. A mixing pot 103 for holding cement paste is mounted on the pallet 102. The pallet 102 is a lifting type pallet 102 that slides on the body 1. The mixing assembly 101 includes a transmission component and mixing blades. The transmission component drives the mixing blades to revolve and rotate. A transparent protective shell 104 is mounted on the body 1, and a protective door 105 is hinged to one end of the protective shell 104. The protective door 105 and the protective shell 104 cover the outer periphery of the mixing pot 103.

[0034] The worker first opens the protective door 105 and places the mixing pot 103 containing cement paste raw materials on the pallet 102. Then, the pallet 102 drives the mixing pot 103 to rise until the mixing blades extend into the mixing pot 103. The worker closes the protective door 105 and starts the transmission mechanism. The transmission mechanism drives the mixing blades to rotate and mix the cement paste. During the mixing process, the protective shell 104 and the protective door 105 intercept splashes of cement paste to prevent the cement paste from splashing out and contaminating the laboratory table. After the mixing is completed, the pallet 102 drives the mixing pot 103 to descend, causing the mixing blades to exit from the mixing pot 103. Finally, the worker opens the protective door 105, removes the mixing pot 103, and pours the cement paste into a mold for testing.

[0035] Reference Figure 2 and Figure 3The support plate 102 has an installation groove 2. The bottom surface of the mixing pot 103 is fixedly connected to an installation column 3 that is inserted into the installation groove 2. The installation column 3 is provided with a fastening component 4, which includes a plug-in plate 41. The plug-in plate 41 is square. The support plate 102 and the installation column 3 have sliding grooves 31 that are slidably engaged with the plug-in plate 41. The sliding grooves 31 are parallel to the radial direction of the installation column 3. The outer surface of the installation column 3 is fixedly connected with a positioning strip 32. The inner side wall of the installation groove 2 has a positioning groove 21 that is slidably engaged with the positioning strip 32. When the positioning strip 32 is inserted into the positioning groove 21, the sliding grooves 31 on the support plate 102 and the installation column 3 are directly connected.

[0036] When installing the mixing pot 103, the worker first inserts the mounting column 3 into the mounting groove 2 by cooperating with the positioning strip 32 and the positioning groove 21. At this time, the two sliding grooves 31 are directly connected. The worker then inserts the plug plate 41 into the connected sliding groove 31 to facilitate subsequent installation work.

[0037] Reference Figure 2 and Figure 3 The plug plate 41 has a cavity 5 inside, and fastening plates 42 are slidably connected to the upper and lower sides of the cavity 5. The outer surfaces of the plug plate 41 and the mounting post 3 are respectively provided with openings 33 for the fastening plates 42 to extend out. The inner sidewalls of the mounting groove 2 are respectively provided with fastening grooves 22 that are plugged into and cooperate with the fastening plates 42.

[0038] Reference Figure 2 and Figure 3 Each cavity 5 has a limiting groove 51 on its inner sidewall. The limiting groove 51 is parallel to the radial direction of the mounting column 3. A limiting block 421 that slides with the limiting groove 51 is fixedly connected to the fastening plate 42. When the limiting block 421 moves to the end of the limiting groove 51 near the fastening groove 22, the fastening plate 42 is fully inserted into the fastening groove 22. When the limiting block 421 moves to the other end of the limiting groove 51, the end face of the fastening plate 42 is flush with the outer end face of the insertion plate 41.

[0039] Reference Figure 2 , Figure 3 and Figure 4 An operating component 6 is provided on the plug-in plate 41. The operating component 6 includes an operating rod 61 rotatably connected inside the plug-in plate 41. The end of the operating rod 61 extends to the outer surface of the plug-in plate 41 and is coaxially fixedly connected to a handwheel 611. A gear 62 is coaxially fixedly connected to the operating rod 61. The gear 62 is rotatably disposed inside the cavity 5. Each gear 62 is meshed with a rack plate 63 corresponding to one of the two fastening plates 42. The rack plate 63 is fixedly connected to the corresponding fastening plate 42.

[0040] After the insertion plate 41 enters the sliding groove 31, the worker rotates the operating lever 61 forward. The operating lever 61 drives the two gears 62 to rotate synchronously forward. Under the guidance and limitation of the limiting block 421 and the limiting groove 51, the gears 62 drive the two rack plates 63 to move synchronously toward the opening 33. The rack plates 63 drive the two fastening plates 42 to extend synchronously from the opening 33 and insert into the fastening groove 22. When the limiting block 421 moves to the end of the limiting groove 51 near the fastening groove 22, the movement of the fastening plates 42 is blocked, and the worker stops rotating the operating lever 61. At this time, the two fastening plates 42 are tightly inserted into the fastening groove 22. With the insertion and cooperation of the fastening plates 42 and the fastening groove 22, the relative rotation between the mounting column 3 and the mounting groove 2 is restricted, thereby effectively reducing the possibility of the mixing pot 103 rotating during the mixing process, ensuring that the mixing blades fully mix the cement paste according to the predetermined trajectory, and improving the mixing effect of the cement paste.

[0041] Reference Figure 2 , Figure 3 and Figure 4 A limiting groove 7 is formed on the outer surface of the operating lever 61 along the axial direction. A locking component 8 is provided in the plug plate 41. Specifically, the locking component 8 includes a locking block 81 that is slidably connected in the limiting groove 51. The locking block 81 is sleeved on the outside of the operating lever 61 and has a square cross section.

[0042] Reference Figure 2 , Figure 3 and Figure 4 The end of the plug plate 41 near the handwheel 611 is provided with a circular groove 9 that rotatably engages with the locking block 81. The inner side wall of the circular groove 9 away from the handwheel 611 is provided with a square groove 10 that engages with the locking block 81. The square groove 10 is used to restrict the rotational movement of the locking block 81. When the limiting block 421 moves to the end of the limiting groove 51 near the fastening groove 22, the locking block 81 and the square groove 10 have the same cross-sectional shape.

[0043] Reference Figure 2 , Figure 3 and Figure 4 The plug plate 41 is threaded with multiple locking bolts 82 near the outer surface of the handwheel 611. In this embodiment, there are two locking bolts 82. The two locking bolts 82 are respectively set on the radial sides of the operating lever 61. The ends of the locking bolts 82 extend into the circular groove 9 and face the locking block 81. A return spring 83 is provided in the limiting groove 7. One end of the return spring 83 is fixedly connected to the inner side wall of the limiting groove 7 near the circular groove 9, and the other end is fixedly connected to the locking block 81. In the natural state of the return spring 83, the locking block 81 is set inside the circular groove 9.

[0044] After the fastening plate 42 is inserted into the fastening groove 22, the worker tightens the locking bolt 82. The locking bolt 82 overcomes the elastic force of the return spring 83 and pushes the locking block 81 out of the round groove 9 and into the square groove 10. The cross-section of the locking block 81 and the square groove 10 restricts the rotation of the locking block 81. Since the locking block 81 is slidably sleeved on the outer surface of the operating rod 61 through the limiting groove 7, the locking block 81 cannot generate relative rotational movement with the operating rod 61. Therefore, the rotational movement of the operating rod 61 is restricted, thereby fixing the position of the fastening plate 42 inserted into the fastening groove 22. This effectively reduces the possibility of the fastening plate 42 being dislodged from the fastening groove 22 due to the worker accidentally touching the operating rod 61 or mechanical vibration, ensuring that the mixing pot 103 is always in a stable connection state and improving the stability of the mixing process.

[0045] When it is necessary to disassemble the mixing pot 103, the worker loosens the locking bolt 82 to move it away from the locking block 81. Under the action of the return spring 83, the locking block 81 disengages from the square groove 10 and moves along the limiting groove 7 into the round groove 9. At this time, the rotation restriction of the locking block 81 and the operating rod 61 is released. The worker rotates the operating rod 61 in the opposite direction to make the fastening plate 42 disengage from the fastening groove 22. The fixing effect of the fastening plate 42 on the plug plate 41 disappears. The worker pulls the plug plate 41 outward to disengage it from the sliding groove 31, and finally pulls the mounting column 3 upward to disengage it from the mounting groove 2. In this way, the mixing pot 103 is disassembled.

[0046] The implementation principle of a multifunctional cement paste mixer according to an embodiment of this application is as follows: When installing the mixing pot 103, the worker first inserts the mounting column 3 into the mounting groove 2 through the cooperation of the positioning strip 32 and the positioning groove 21. At this time, the two sliding grooves 31 are directly connected. Then, the worker rotates the operating rod 61 in the forward direction. The operating rod 61 drives the two gears 62 to rotate synchronously in the forward direction. Under the guidance and limitation of the limiting block 421 and the limiting groove 51, the gears 62 drive the two rack plates 63 to move synchronously toward the opening 33. The rack plates 63 drive the two fastening plates 42 to move synchronously from the opening 33. 3. Extend and insert into the fastening groove 22. When the limiting block 421 moves to the end of the limiting groove 51 near the fastening groove 22, the movement of the fastening plate 42 is blocked, and the worker stops rotating the operating lever 61. At this time, both fastening plates 42 are tightly inserted into the fastening groove 22. With the insertion and cooperation of the fastening plate 42 and the fastening groove 22, the relative rotation between the mounting column 3 and the mounting groove 2 is restricted, thereby effectively reducing the possibility of the mixing pot 103 rotating during the mixing process, ensuring that the mixing blades fully mix the cement paste according to the predetermined trajectory, and improving the mixing effect of the cement paste.

[0047] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
