Description

Technical Field

[0001] The utility model relates to the technical field of concrete truck cleaning, in particular to a cleaning device for a concrete transport truck. Background Art

[0002] Concrete is widely used in the construction industry due to its excellent durability, cost-effectiveness and versatility. Concrete trucks, often called mixer trucks, are one of the key equipment used to transport concrete from the mixing plant to the construction site. These transport vehicles are equipped with a rotating mixing drum to ensure that the concrete remains uniform and prevents solidification during transportation. Once the concrete begins to solidify, it is very difficult to remove, so the cleaning of concrete mixer trucks is crucial. If the residual concrete in the mixing tank is not cleaned up in time, it may solidify, thereby affecting the capacity and mixing efficiency of the mixing tank, or even causing mechanical failure. More importantly, keeping the equipment clean avoids potential quality issues, as old, uncleaned concrete residues may be mixed into new batches of concrete, affecting its performance.

[0003] The cleaning of concrete mixer trucks is usually done by manpower. In order to clean the inner wall of the concrete mixing tank, workers need to enter the circular storage tank for physical cleaning. In this process, since the wall of the mixing tank is curved, workers need to rotate the mixing tank while cleaning to ensure that the cleaning operation covers all areas in the tank. This cleaning process is not only complicated and inefficient, but also easily leads to areas that are not cleaned due to work fatigue and misoperation.

[0004] What is more serious is that this cleaning method has safety hazards. During the cleaning process, the solidified or semi-solidified concrete attached to the tank top or tank wall may fall off due to the cleaning operation or the rotation of the tank body, which is a great safety threat to the personnel working in the tank.

[0005] Therefore, those skilled in the art have proposed a cleaning device for a concrete transport vehicle. Utility Model Content
