Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning devices, in particular to a concrete drilling quick dust cleaning device. Background Art

[0002] Concrete is a general term for engineering composite materials that are cemented into a whole by cementitious materials. It refers to cement concrete obtained by mixing cement as cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. In the process of nuclear power engineering construction, in order to test the installation strength of expansion bolts, it is necessary to drill holes in the concrete. During the drilling process, in order to reduce the influence of dust on the correct installation of expansion bolts, it is necessary to clean the concrete reinforcement holes. At present, the cleaning is carried out by sending air into the reinforcement holes through a blowing pipe, which is not convenient for direct blowing on the hole wall;

[0003] In order to solve the above problems, the prior art proposes a concrete rebar hole cleaning nozzle with patent publication number CN210207260U, which is provided with a through hole on the side wall of the inner tube, so that the airflow can be sprayed outward at the through hole when the air outlet end of the inner tube is sprayed outward, and the airflow sprayed outward from the through hole can directly blow the hole wall of the rebar hole. Although it is convenient to blow directly on the hole wall, it is necessary to adjust the position of the outer sleeve on the inner tube during use to close or connect the through hole. The stability of the outer sleeve on the inner tube is poor when adjusting, and it is not convenient to limit it. It is easy to move at will during cleaning, and it needs to be adjusted manually multiple times, which will reduce the cleaning efficiency of the concrete rebar hole. Utility Model Content
