[0002] Cement: A powdered hydraulic inorganic gelling material that forms a slurry when stirred with water.

DETAILED DESCRIPTION

[0027] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 6 As shown, a cement mortar mixer of the present invention comprises a frame 3, a tank body 8, a lifting mechanism, a stirring mechanism and a discharge mechanism. The stirring mechanism is provided on the upper portion of the frame 3, the lifting mechanism is provided on the lower portion of the frame 3, the lifting mechanism is drivably connected to the tank body 8, the upper portion of the discharge mechanism is provided on the frame 3, and the lower portion of the discharge mechanism is movably connected to the tank body 8;

[0029] The unloading mechanism includes a folding cover barrel 9, a scraping wall assembly 1 and a first magnetic component 15. The folding cover barrel 9 is arranged directly above the tank body 8. The top of the folding cover barrel 9 is connected to the frame 3. The bottom of the folding cover barrel 9 is provided with the first magnetic component 15. The folding cover barrel 9 is detachably connected to the tank body 8 through the first magnetic component 15. The upper part of the scraping wall assembly 1 is connected to the frame 3, and the lower part of the scraping wall assembly 1 is slidably connected to the inner surface of the folding cover barrel 9.

[0030] The working principle of the present invention is as follows: when cement mortar and water need to be stirred and mixed during actual production and use, the cement mortar and water can be put into the tank body 8, and then the lifting mechanism is operated to make the lifting mechanism drive the tank body 8 to rise, so that the tank body 8 is set outside the stirring mechanism, and then the stirring mechanism is operated to make the stirring mechanism stir and mix the raw materials inside the tank body 8. When the stirring is completed, the first magnetic attraction member 15 can be operated to make the first magnetic attraction member 15 adsorb the top surface of the tank body 8, and then the lifting mechanism is operated to make the lifting mechanism drive the tank body 8 to rise. 8 descends while driving the folding cover tube 9 to pull down, so that the tank body 8 is separated from the stirring mechanism, and the folding cover tube 9 is covered on the outside of the stirring mechanism, and then the stirring mechanism is operated to rotate at high speed, so that the cement mortar stuck to the stirring mechanism is thrown into the inside of the tank body 8, and then the scraping component 1 can be operated to make the scraping component 1 scrape the cement mortar stuck to the inner wall of the folding cover tube 9 into the inside of the tank body 8, and then the adsorption force of the first magnetic suction component 15 on the tank body 8 is released, so that the folding cover tube 9 is retracted, and then the mixed raw materials in the tank body 8 are taken out for test block production.

[0031] Furthermore, the wall scraping assembly 1 includes a linear drive component 104, a movable ring 103 and an annular scraper 102. The linear drive component 104 is detachably connected to the upper part of the frame 3, and the movable ring 103 is movably connected inside the folding cover tube 9. The linear drive component 104 is linearly driven and connected to the movable ring 103. The annular scraper 102 is provided on the outside of the movable ring 103, and the outer side of the annular scraper 102 is in contact with the inner surface of the folding cover tube 9.

[0032] From the above description, it can be seen that when it is necessary to remove the cement mortar stuck to the inner wall of the folding cover tube 9, the position of the stirring paddle 12 on the stirring mechanism can be adjusted in advance so that there will be no interference in the subsequent scraping process. Then, the linear drive member 104 is operated to drive the annular scraper 102 to move through the moving ring 103, so that the annular scraper 102 scrapes the cement mortar on the inner wall of the folding cover tube 9 into the inside of the tank body 8.

[0033] Furthermore, the stirring mechanism includes a first rotating drive member 10, a stirring shaft 11 and a stirring paddle 12.

The first rotating drive member 10 is drivingly connected to the stirring shaft 11.

[0034] From the above description, it can be seen that when it is necessary to stir and mix the raw materials in the tank body 8, the first rotating drive member 10 can be operated, so that the first rotating drive member 10 drives the stirring paddle 12 through the stirring shaft 11 to mix the raw materials. When it is necessary to remove the cement mortar stuck on the stirring paddle 12, the tank body 8 can be separated from the stirring paddle 12 first, and the folding cover tube 9 can be covered on the outside of the stirring paddle 12. Then, the stirring paddle 12 is driven by the first rotating drive member 10 to rotate at high speed to throw the cement mortar out of the outside of the stirring paddle 12.

[0035] Furthermore, the lifting mechanism includes a second rotating drive member 2, a screw 4, a slider 5 and a lifting plate 7. A slide groove 13 is provided at the lower part of the frame 3. One side of the slider 5 is slidably connected to the inside of the slide groove 13, and the other side of the slider 5 is connected to one side of the lifting plate 7. The screw 4 is passed through the middle of the slider 5 and is rotatably connected to the frame 3. The second rotating drive member 2 is drivingly connected to the screw 4. The other side of the lifting plate 7 is provided with a placement groove adapted to the tank body 8. The placement groove is provided directly below the folding cover tube 9, and the tank body 8 is detachably connected to the placement groove.

[0036] From the above description, it can be seen that when it is necessary to stir and mix the raw materials in the tank body 8, the second rotating drive member 2 can be operated to drive the screw 4 to rotate, and then the slider 5 drives the tank body 8 to rise through the lifting plate 7, so that the tank body 8 is mounted on the outside of the stirring mechanism, and then the stirring mechanism is operated to mix the raw materials inside the tank body 8. After the stirring is completed, the second rotating drive member 2 can be operated to make the lifting plate 7 drive the tank body 8 to separate from the outside of the stirring mechanism, so that the mixed raw materials can be better taken out.

[0037] Furthermore, a second magnetic member 14 is included. The lower part of the placement slot is also provided with the second magnetic member 14, and the second magnetic member 14 is detachably connected to the bottom of the tank body 8.

[0038] From the above description, it can be seen that when it is necessary to better fix the tank body 8 to the placement groove in the lifting plate 7, the second magnetic suction component 14 can be operated to make the second magnetic suction component 14 adsorb and fix the bottom of the tank body 8, so that the raw materials inside the tank body 8 can be more stably placed on the lifting plate 7 during mixing.

[0039] Furthermore, it also includes a slide rod 101, a plurality of the slide rods 101 are provided on the movable ring 103, and a slide hole adapted to the slide rod 101 is provided on the frame 3, and the slide rod 101 is slidably connected to one of the slide holes.

[0040] From the above description, it can be seen that the movable ring 103 can slide more stably on the frame 3 through the slide rod 101, so that the annular scraper 102 can better scrape the inner wall of the folding cover tube 9.

[0041] Furthermore, it also includes a base 6, and the bottom of the frame 3 is fixedly connected to the base 6.

[0042] From the above description, it can be seen that this is conducive to more stable operation of the device.

[0043] Furthermore, it also includes a PLC controller, which is electrically connected to the lifting mechanism, the stirring mechanism and the unloading mechanism respectively.

[0044] From the above description, it can be seen that it is beneficial to adjust the parameters of the cement mortar mixer through the PLC controller, and it makes it more convenient for operators to operate the cement mortar mixer.
