[0002] In the process of building, bridge and tunnel construction in the market, concrete is generally needed for construction. Therefore, during construction, concrete pumps are often needed to transport concrete.

[0003] A concrete pump consists of a pump body and a delivery pipe. When concrete is being transported inside the pipe, if the inside of the pipe is not cleaned initially and the pump's delivery speed is not properly selected, it will cause concrete blockage inside the pipe, affecting the overall concrete delivery efficiency.

[0004] In the existing market, generally, a dredging mechanism is provided inside the pipeline for internal dredging work. However, in the actual processing process, the length of the pipeline is not fixed according to the construction location and distance. When the dredging distance is long, a corresponding dredging mechanism is provided inside each pipeline, which not only increases the production cost of the entire pipeline, but also the dredging mechanism is provided inside each section of the pipeline, which affects the flow rate of concrete and increases the efficiency of blockage.
