[0002] When mixing ready-mixed concrete, concrete machinery is required. Concrete machinery is a type of equipment that uses machines to replace manual labor in mixing cement, sand, gravel, and water according to a specific mix ratio to produce concrete needed for construction projects and other production activities. Currently used ready-mixed concrete mixers are difficult to clean after use, requiring a significant amount of manpower and resulting in resource waste. Therefore, designing a ready-mixed concrete mixer with a cleaning function is crucial. For example:

[0003] A commercial concrete mixer with easy unloading, authorized by announcement number CN222039090U, provides the following advantages:

[0004] 1. This easy-to-unload commercial concrete mixer, through the design of a rotating assembly and a threaded slurry rod, allows concrete inside the mixing structure to enter the lifting pipe. A drive motor rotates the top connecting block, which, via a quick-release assembly, rotates the threaded slurry rod. The threaded slurry rod then lifts the concrete inside the lifting pipe, achieving convenient and quick concrete lifting and unloading, thus improving work efficiency. Furthermore, the quick-release assembly allows for easy disassembly and cleaning of the threaded slurry rod. Simply pull out the elastic insert and the limiting rod sequentially to remove the rod from the frame, detaching it from the rotating assembly surface. This facilitates easy disassembly and cleaning of the lifting structure, reducing the complexity of cleaning operations.

[0005] Based on existing solutions and actual production and processing applications, existing commercial concrete mixers have the following shortcomings, such as:

[0006] While existing commercial concrete mixers can disassemble and clean their lifting structures, it is difficult to clean the inside of the mixer, requiring a large amount of manpower and wasting resources. Therefore, this utility model provides a commercial concrete mixer with a cleaning function to solve the above-mentioned problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a commercial concrete mixer with cleaning function, including a mixing chamber 1, a top cover 2, a drive rod 3, a mixing rod body 4, a support base 5, a self-locking wheel 6, a discharge pipe 7, a handle 8, a connecting bolt 9, a protective cover 10, a feed inlet 11, a protective plate 12, a drain outlet 13, a guide pipe 14, a connection port 15, a collection pipe 16, a water inlet 17, a water inlet valve 18, a motor 19, a guide rod 20, a limiting block 21, a connecting plate 22, and a scraper body 23.

[0029] Specific examples Figure 1 and Figure 5 As shown, first place the self-locking wheel 6 provided on the lower side of the support base 5 on a horizontal ground, pull the handle 8 provided on the outside of the mixing chamber 1 so that the self-locking wheel 6 rolls on the horizontal ground. When the mixing chamber 1 reaches the appropriate position, stop pulling the handle 8. At this time, the self-locking wheel 6 is in a self-locking state. Then, align the top cover 2 with the top of the mixing chamber 1 and press it down. Friction is generated between the inner wall of the top cover 2 and the outer wall of the mixing chamber 1. The top cover 2 and the mixing chamber 1 are slidably connected until the upper surface of the mixing chamber 1 contacts the top cover 2.

[0030] After the mixing chamber 1 and the top cover 2 are engaged, the top cover 2 covers the outside of the mixing chamber 1. The diameter of the top cover 2 is larger than that of the mixing chamber 1. The connecting bolt 9 is screwed on horizontally. The connecting bolt 9 has a threaded connection on the outside. After the connecting bolt 9 is screwed on, the connection gap between the top cover 2 and the mixing chamber 1 is shortened. Both the top cover 2 and the mixing chamber 1 are threaded to the connecting bolt 9. The top cover 2 and the mixing chamber 1 are fastened together by the connecting bolt 9. A protective cover 10 is provided on the upper side of the top cover 2. The guide tube 14 extends outward from the inside of the protective cover 10. The connecting port 15 is nested on the outside of the guide tube 14. The guide tube 14 and the connecting port 15 are welded together so that the connecting port 15 is fixed on the outside of the guide tube 14, which facilitates the rapid assembly of the commercial concrete mixer.

[0031] Specific examples Figure 1 and Figure 3 As shown, the required commercial concrete raw materials are poured into the feed inlet 11 from above. The motor 19 inside the support base 5 is turned on. After the motor 19 is powered on, it drives the guide rod 20 connected to the upper side to rotate. The upper side of the guide rod 20 is connected to the drive rod 3, so that the drive rod 3 moves with the guide rod 20. The outer end of the drive rod 3 is provided with a vertically arranged mixing rod body 4, and the mixing rod body 4 is evenly spaced on the drive rod 3. The outer end of the mixing rod body 4 is provided with a scraper body 23. The mixing rod body 4 mixes the commercial concrete raw materials inside the mixing chamber 1, and the scraper body 23 mixes the raw materials adhering to the inner wall of the mixing chamber 1. The residue of the ready-mixed concrete is scraped off. A limiting block 21 passes through the upper end of the drive rod 3. A connecting plate 22 is set at an equal angle on the outside of the limiting block 21. The outer end of the connecting plate 22 is connected to the inner wall of the top cover 2. When the drive rod 3 rotates, friction is generated between the outer wall of the drive rod 3 and the inner wall of the limiting block 21. The drive rod 3 and the limiting block 21 are slidably connected. Under the action of the limiting block 21, the drive rod 3 always remains vertical. The movement direction of the drive rod 3 is limited. The mixing rod body 4 on the outside of the drive rod 3 is always in a horizontal mixing state, which makes it easy for the ready-mixed concrete mixer to limit the direction of the mixing rod.

[0032] Specific examples Figure 1 , Figure 2 and Figure 4As shown, after the ready-mixed concrete is mixed, the valve inside the discharge pipe 7 is opened. The discharge pipe 7 is located on the right side of the mixing chamber 1, allowing the mixed ready-mixed concrete to be discharged from the discharge pipe 7. When cleaning the mixing chamber 1 is required, cold water is introduced from the upper end of the water inlet 17, and the water inlet valve 18 is opened. The cold water enters the interior of the manifold 16 through the water inlet 17. The connection ports 15 are evenly spaced inside the manifold 16, allowing the cold water to be distributed through the connection ports 15. The connection ports 15 are welded to the guide pipe 14, and the cold water flows through the guide pipe 14. 4. The cold water enters the interior of the drain outlet 13 and is sprayed through the through holes opened inside the protective plate 12. After the cold water reaches the interior of the mixing chamber 1, the rotating mixing rod body 4 and scraper body 23 will drive the cold water to stir inside the mixing chamber 1. The cold water moves at high speed inside the mixing chamber 1 to clean the interior of the mixing chamber 1. After cleaning, the valve inside the discharge pipe 7 is opened to discharge the sewage, which facilitates the cleaning function of the commercial concrete mixer. This is the usage method of the commercial concrete mixer with cleaning function.
