[0002] Concrete, as one of the most important building materials in modern construction, is widely used in various civil engineering projects such as houses, bridges, roads, and tunnels. Concrete mixing equipment is an indispensable key equipment in the concrete construction process. Its main function is to uniformly mix cement, aggregates (such as sand and gravel), water, and possible admixtures in a certain proportion to obtain a stable concrete mixture.

[0003] Currently, most concrete mixing equipment relies mainly on manual cleaning after use. This involves operators using brushes or scrapers to manually clean the inner wall of the mixing drum. This method is not only labor-intensive and inefficient, but also has limited cleaning effect and is difficult to completely remove firmly attached cement residues. Utility Model Content

[0030] Example 1

[0031] As attached Figures 1 to 8 The concrete mixing equipment shown includes: a support frame 1, a mixing drum 11 fixedly installed on the top of the support frame 1, a drive motor 12 fixedly installed on the support frame 1, a mixing rod 13 provided inside the mixing drum 11, a drive shaft at the top of the drive motor 12 connected to the bottom end of the mixing rod 13, and a cleaning mechanism provided on the mixing rod 13 for cleaning cement on the inner wall of the mixing drum 11.

[0032] In this process, concrete raw materials are put into the mixing drum 11 when mixing concrete. The driving motor 12 is started to drive the mixing rod 13 to rotate and mix. One end of the support frame 1 has a reserved position for a feeding mechanism, which can be installed to feed the raw materials through the hole at the top of the mixing drum 11. After the mixing is completed, the cleaning mechanism is installed on the mixing rod 13 to clean the cement residue on the inner wall of the mixing drum 11, making the cleaning process simpler and more convenient.

[0033] Example 2

[0034] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:

[0035] The cleaning mechanism includes: a support platform 2, a mounting rod a21, a mounting rod b22, a sleeve 23, a slot 24, a connecting frame a25, a plug-in block a26, and a cleaning scraper 27. The top of the stirring rod 13 is fixedly connected to the support platform 2, the top of the support platform 2 is fixedly connected to the mounting rod a21, and the top of the mounting rod a21 is fixedly connected to the mounting rod b22. Both the mounting rod a21 and the mounting rod b22 are hexagonal in shape. Both the mounting rod a21 and the mounting rod b22 are fitted with a sleeve 23. Multiple slots 24 are opened around the sleeve 23. A connecting frame a25 is provided on one side of the slot 24. Plug-in blocks a26 are fixedly connected to both ends of the connecting frame a25 near the slot 24. The other end of the connecting frame a25 is fixedly connected to the cleaning scraper 27. The top of the mounting rod b22 is provided with a threaded hole 28, and a clamping bolt 29 is threaded inside the threaded hole 28. The top of the plug-in block a26 and the plug-in block b31 located at the bottom are fixedly connected to a pressure plate 210.

[0036] Specifically: When cleaning residual cement on the inner wall of the mixing drum 11, open the dust cover on top of the mixing drum 11, and then install the two sleeves 23 onto the corresponding mounting rods a21 and b22 respectively, ensuring that the slots 24 on the sleeves 23 correspond. The hexagonal structure of the mounting rods a21 and b22 can drive the sleeves 23 to rotate, preventing the sleeves 23 from rotating on their own, and not affecting the up-and-down movement of the sleeves 23 for easy installation and disassembly. Then, align the insertion blocks a26 at both ends of the connecting bracket a25 with the slots 24 on the two sleeves 23 and insert them into the slots 24 respectively, so that the cleaning scraper 27 fits against the inner wall of the mixing drum 11, and the pressure plate 210 can push the bottom sleeves... Press down on the sleeve 23 to prevent it from sliding up and down. Then screw the clamping bolt 29 into the threaded hole 28. The clamping bolt 29 presses down on the top plug block a26 and the sleeve 23 to prevent the connecting frame a25 from coming off. This allows the cleaning scraper 27 to rotate when the mixing rod 13 rotates. The rotating cleaning scraper 27 can scrape off the cement residue on the inner wall of the mixing drum 11, making the cleaning process simple and quick. After cleaning, unscrew the clamping bolt 29 to release the fixing of the connecting frame a25. Lift the connecting frame a25 upwards to remove the plug block a26 from the slot 24, completing the disassembly of the connecting frame a25. Then take out the cleaning scraper 27 to facilitate cleaning the cement on the connecting frame a25 and the cleaning scraper 27.

[0037] In a preferred embodiment, a connecting frame b3 is provided inside the mixing drum 11. Insert blocks b31 are fixedly connected to both ends of the connecting frame b3 near the mixing rod 13, and a mixing blade 32 is fixedly connected to one end of the bottom of the connecting frame b3.

[0038] Furthermore, when mixing is required, replace the mixing blade 32, insert the inserts b31 at both ends of the connecting frame b3 into the slots 24 on the two sleeves 23, and then screw the clamping bolts 29 into the threaded holes 28 to fix the connecting frame b3. This allows the connecting frame b3 and the mixing blade 32 to rotate when the mixing rod 13 rotates, thereby mixing the concrete. Unscrew the clamping bolts 29 to release the fixing of the connecting frame b3, and then disassemble the connecting frame b3. Remove the connecting frame b3 and the mixing blade 32 from the inside of the mixing drum 11 to facilitate cleaning the concrete on the connecting frame b3 and the mixing blade 32.

[0039] Example 3

[0040] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details:

[0041] A discharge port 4 is provided at the bottom of the mixing drum 11. A discharge platform 41 is fixedly connected to the bottom of the mixing drum 11 near the discharge port 4. A rotating groove 42 is provided between the mixing drum 11 and the discharge port 4. A baffle 43 is provided inside the rotating groove 42. Two mounting rings 44 are fixedly connected to the outside of the mixing drum 11. A rotating rod 45 is provided between the inside of the mounting rings 44. A connecting block 46 is fixedly connected to the outside of the baffle 43. The bottom end of the rotating rod 45 is connected to the top of the connecting block 46.

[0042] Specifically: When concrete needs to be discharged, the rotating rod 45 is manually rotated to one side. When the rotating rod 45 rotates, it drives the connecting block 46 and the baffle 43 to rotate. The rotating rod 45 is restricted by the mounting ring 44, so that the rotating rod 45 can only rotate in the mounting ring 44. The baffle 43 rotates out of the rotating groove 42, so that the discharge port 4 opens and the concrete flows out, falls onto the discharge platform 41 and slides down the slope to be discharged. After the discharge is completed, the rotating rod 45 is rotated back to the initial position, so that the baffle 43 rotates into the rotating groove 42 and blocks the discharge port 4 to prevent the concrete from flowing out.

[0043] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
