Abstract

The utility model relates to a scale removing machine for impacting and removing scale which oxidizes iron scale at high temperature on the surface of a rolled steel billet, which is provided with a height adjustment mechanism of a water collecting pipe; the end part of the water collecting pipe is arranged in a slide block of the mechanism; an anti-splash closed mechanism of the water collecting pipe surrounds the water collecting pipe into a closed space; a protection board of the water collecting pipe is covered on the water collecting pipe and is connected with a rotary crank arm of which the upper end is fixed to a support frame mechanism and the lower end is connected with a shaft end extending from an air cylinder; the air cylinder is connected with a pneumatic control cabinet driven by an air source or a power supply. The utility model has the advantages that the utility model improves the environment of technological operation, solves the problem that an injection mechanism of the water collecting pipe can not follow the thickness of the steel billets and the striking strength of injection water flows to automatically adjust the height, and avoids the phenomena that high-pressure water bloom generated by lifting edges of the rolled steel billet or generated during the work of the water collecting pipes mutually erodes to oxidize the iron scale and to damage the water collecting pipes.
