[0002] Concrete is an essential material for construction, mainly composed of cement, sand and gravel. During the mixing process, it needs to be stirred by a stirring device in order to evenly mix the various raw materials. Existing concrete mixing devices for construction do not have a cleaning function, because the concrete will stick to the inner wall of the mixing tank. When it is not used, the concrete will solidify on the inner wall of the mixing tank, which will affect the quality of the concrete when it is used again.

By setting a cleaning structure, after use, the connecting rod is pulled out and connected to the threaded head through a nut. After the connection, the motor is started, so that the connecting rod drives the scraper seat to rotate through the annular bar, and the concrete on the inner wall of the mixing tank can be scraped off to avoid residue and avoid affecting the secondary use after the concrete solidifies. The cleaning is more convenient and quick, and the convenience of later maintenance is improved.

[0004] When the stirring device in the above application cleans the inner wall of the mixing tank, the motor is started by sliding the connecting rod and connecting it with the threaded head using a nut, so that the motor drives the scraper seat to rotate through the connecting rod, thereby scraping off the concrete residue on the inner wall of the mixing tank; however, there is no limiting structure between the scraper seat and the annular bar in the above application, so the scraper seat and the annular bar are easily separated, and at this time, the inner wall of the mixing tank cannot be cleaned well.
