[0002] In road maintenance and repair work, concrete mixing tanks are key equipment. A large amount of concrete often remains on their inner walls due to mixing operations. If not cleaned in time, it will not only affect the quality of subsequent mixing operations, but may also cause equipment damage due to concrete caking.

[0003] The interior of the concrete mixing tank on the existing repair device is mostly lacking a mechanism that can scrape and clean the concrete slag remaining on the inner wall of the tank body, resulting in reliance on manual handheld tools to scrape and clean the residual concrete slag inside the tank body, which is not only troublesome and inefficient, but also poses a safety hazard. In addition, although some concrete mixing tanks are equipped with a mechanism for scraping and cleaning the residual concrete slag, most of them lack a spray flushing mechanism used in conjunction with the scraping and cleaning mechanism, resulting in it being difficult to thoroughly and effectively clean the residual concrete slag relying solely on the scraping and cleaning mechanism. Summary of the invention

[0004] In view of this, the present invention provides a directionally movable pavement concrete repairing device to solve the problem that there is a lack of a mechanism inside the concrete mixing tank that can scrape and clean the concrete slag remaining on the inner wall of the tank body, resulting in reliance on manual handheld tools to scrape and clean the residual concrete slag inside the tank body, which is not only troublesome and inefficient, but also poses a safety hazard.
