Description

[0002] With the rapid development of national highway construction, traditional highway construction machinery is no longer able to meet the technological innovation requirements for rapid, efficient, and safe highway construction. In particular, existing cement slurry spraying vehicles, many of which are modified agricultural vehicles, are bulky and cannot be directly towed. Furthermore, loading cement onto these cement slurry spraying vehicles relies on manual labor, which presents significant constraints and safety risks.

[0003] Chinese patent publication number CN201981471U discloses a cement spraying machine, comprising a mixing tank, a stirrer, a generator, a liquid pump, a spray head, and a chassis.

However, when this technical solution is used, the injected slurry is prone to the presence of hardened lumps. Directly mixing it with water not only makes it difficult to mix, but also easily clogs the liquid pump, reducing spraying efficiency. Furthermore, the spray head's spray position requires manual adjustment, reducing ease of use and work efficiency.

[0004] For this reason, a cement spraying machine is proposed.
