发明名称 Concrete truck delivery chute cleaning tool
摘要 A tool for cleaning concrete truck delivery chutes. The tool comprises an elongated handle portion having a generally disc-shaped head portion carried at one end thereof. The head portion comprises a substantially semicircular rigid plate portion extending substantially perpendicular to the handle portion and configured to conform to the inner contour of a concrete truck delivery chute. A substantially semicircular flexible portion extends perpendicularly from the handle portion substantially opposite to the rigid portion and projects forwardly at an angle of approximately 45 DEG from the plane of the rigid portion. The flexible portion is configured to conform to the inner contour of a concrete truck delivery chute and tapers radially outward to form a squeegee edge to facilitate removal of water from the chute.
