[0002] Concrete pump truck is a kind of equipment widely used in modern construction, can efficiently transport concrete from mixer to the specified position of construction site. It is transported to remote, high-rise or difficult-to-reach place by high-pressure pumping system, greatly improves construction efficiency, especially in large-scale construction projects. However, with the concrete pumping work, the pipeline inside is often affected by coarse granular material, impurities etc. in concrete, and the phenomenon of blockage occurs, affects construction efficiency, and even causes equipment damage and project delay.

[0003] The existing pipeline anti-blocking structure usually relies on simple filter device or grid screening system to prevent larger granular material from blocking the pipeline. However, with the size difference of granular material in concrete pouring process, especially the appearance of larger particles, the traditional structure is difficult to completely avoid their deposition or jam in the pipeline, leading to great difficulty in cleaning later, and even manual disassembly of the pipeline, increasing the time and cost of construction.

[0004] Once the existing anti-blocking structure is blocked, the cleaning process usually needs to rely on manual operation, and the steps of disassembling the pipeline and cleaning the material are not only time-consuming and laborious, but also very easy to cause damage to the pipeline, affecting the later use. This cleaning method does not have good flexibility and efficiency, and frequent disassembly and assembly increase the maintenance cost of equipment and the labor intensity of workers.
