[0002] Concrete is an important building material, typically made by mixing cement, sand, gravel, and water in a specific ratio. After hardening, it possesses properties such as pressure resistance, water resistance, and fire resistance. It is mainly used in the construction of building structures, foundations, underground structures, enclosure structures, and roofs. During concrete preparation, a mixer is used to mix various raw materials such as cement, sand, and gravel to process them into concrete of a suitable consistency.

[0003] During operation, a concrete mixer rotates its drum by accumulating material, thus mixing, tumbling, and dispersing various materials inside. However, existing mixers make it inconvenient to clean the inside of the drum promptly, hindering repeated operation. Therefore, this paper proposes a concrete mixer that is easy to clean in a timely manner to solve the aforementioned problems. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a concrete mixer that is easy to clean in a timely manner, including a support frame 1, a first servo motor 2 inside the support frame 1, and an output shaft on the first servo motor 2. The other end of the output shaft is connected to a fixed frame 3, and a rotating block is provided on the other side of the fixed frame 3. The other end of the rotating block is inserted into another set of support frames 1. A motor 4 is provided inside the fixed frame 3, and an output shaft is provided on the motor 4. A mixing tank 5 is provided at the other end of the output shaft, and sliders are provided on the outer walls of both sides of the mixing tank 5. The sliders are respectively inserted into the fixed frame 3.

[0020] Furthermore, the fixed frame 3, under the action of the first servo motor 2, forms a rotating structure with the support frame 1 through the output shaft and the rotating block. The mixing tank 5, under the action of the motor 4, also forms a rotating structure within the fixed frame 3 through the output shaft. Thus, the motor 4 can drive the mixing tank 5 to rotate so as to mix various concrete raw materials. At the same time, the first servo motor 3 can drive the mixing tank 5 to rotate so as to load and unload various concrete raw materials.

[0021] The fixed frame 3 has an electric push rod 6 located inside the front end, and the electric push rod 6 has a telescopic arm 7. Hollow rods 8 are located above and below the electric push rod 6 on the fixed frame 3, and telescopic rods 9 are inserted inside the hollow rods 8. The other end of the telescopic arm 7 and the telescopic rod 9 are connected to the concave fixed frame 10.

[0022] Furthermore, under the action of the electric push rod 6, the concave fixing frame 10 forms a horizontal pushing structure with the fixing frame 3 through the telescopic arm 7, hollow rod 8, telescopic rod 9, thereby adjusting the insertion position of the nozzle 16 under the action of the electric push rod 6, thus ensuring that the nozzle 16 can be inserted into the mixing tank 5 to rinse its inner wall.

[0023] The concave fixing frame 10 has a second servo motor 11 inside, and one end of the output shaft of the second servo motor 11 is connected to the rotating shaft 12 through a coupling. The other end of the rotating shaft 12 is inserted into the concave fixing frame 10, and the rotating shaft 12 has a fixing plate on its outer wall. It should be noted that the electrical equipment in this device is connected to the power supply equipment through a power cord, and its working status is monitored in real time by a controller, so as to ensure that the device can work normally.

[0024] Furthermore, under the action of the second servo motor 11, the water inlet pipe 13 forms a rotating structure with the concave fixing frame 10 through the rotating shaft 12, thereby facilitating timely cleaning of the mixing tank 5 through the rotatable nozzle 16 assembly while avoiding affecting the normal operation of the mixing tank 5.

[0025] A water inlet pipe 13 is inserted through the fixed plate, and one end of the water inlet pipe 13 is connected to the water source through a water pump. The other end of the water inlet pipe 13 is spirally connected to a spiral tube 14. A connector is provided on the spiral tube 14, and a spray arm 15 is provided on the connector. Multiple sets of spray nozzles 16 are evenly provided on the spray arm 15.

[0026] Furthermore, the inner wall of the water inlet pipe 13 is provided with threads that fit with the outer wall of the spiral pipe 14, and the water inlet pipe 13 forms a communication structure with the nozzle 16 through the spiral pipe 14 and the spray arm 15, so that the nozzle 16 assembly can be installed and removed through the spiral pipe 14, thereby facilitating timely cleaning of the mixing tank 5 through the nozzle 16 assembly.

[0027] Working principle: Before using the concrete mixer 5, which is designed for easy and timely cleaning, the spiral tube 14 can be spirally installed onto the water inlet pipe 13 to facilitate the subsequent timely driving of the nozzle 16 assembly. After the concrete mixing is completed, the mixing drum 5 can be rotated by the first servo motor 2 to unload the mixed concrete. After unloading, the mixing drum 5 can be rotated to a horizontal position by the first servo motor 2, and the rotating shaft 12 can be rotated by the second servo motor 11 to rotate the nozzle 16 to the feed inlet of the mixing drum 5, thereby spraying water onto the mixing drum 5. The mixing drum 5 is initially cleaned by rotating. After initial cleaning, the first servo motor 2 drives the drum 5 to rotate again to treat the wastewater inside. After wastewater treatment, the electric push rod 6 is activated. The electric push rod 6 drives the nozzle 16 assembly to move horizontally through the telescopic arm 7, hollow rod 8, and telescopic rod 9, so that the nozzle 16 can penetrate into the mixing drum 5 to rinse the inner wall of the mixing drum 5, thereby ensuring the cleanliness of the mixing drum 5 so that the mixing drum 5 can be used for subsequent mixing. This is the usage process of the concrete mixer that is easy to clean in a timely manner.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
