[0002] The shield machine, whose full name is shield tunnel boring machine or full-section tunnel boring machine, is a tunnel boring machine that uses the shield method. The construction method of the shield machine is that the tunnel boring machine lays the supporting segments of the tunnel while excavating. The machine has the characteristic of completing the tunnel in one excavation, and it completes the entire process from excavation, advancement, and propping up.

[0003] At present, when shield machines are operating in clay, sticky sand and other strata, the debris is usually transported by belts. As the shield excavation extends, a thick layer of debris will be retained on the belt surface. However, it is currently difficult to clean the surface of the shield machine belt. The debris remaining on the belt surface will affect the subsequent transportation of the debris by the belt, and the debris is easy to fall inside the tunnel when the belt is running, which will cause pollution to the working environment. Therefore, those skilled in the art provide a shield machine belt cleaner to solve the problems raised in the above background technology. Utility Model Content
