Abstract:
1. A scraping apparatus assembly for use with a pressure cleaning assembly comprising a pressure cleaning wand and a nozzle for emitting a fluid to remove debris from a planar work surface, the scraping apparatus assembly comprising: a scraping blade fabricated of a planar material, the scraping blade comprising a scraping section located at a first end thereof and a planar mounting section located at a second, opposite end thereof, the scraping blade defined having a first material edge and a second material edge, wherein the first material edge and a second material edge are located opposite one another, the scraping section having a linear blade edge formed along the first material edge thereof and the planar mounting section extending inward from the second material edge, wherein the linear blade edge comprises a chisel edge, said chisel edge extends generally perpendicular to a longitudinal axis of the scraping blade; a scraping apparatus spacer block having a pipe connection section provided along an upper portion of the scraping apparatus spacer block that is parallel to a longitudinal axis of the pressure cleaning wand and a planar blade-engaging receiving surface provided on a lower portion of the scraping apparatus spacer block that is oriented tangential to a radial direction of the pressure cleaning wand, wherein the scraping apparatus spacer block provides a spatial arrangement between the pipe connection section and the planar blade receiving surface for maintaining the wand and the scraping blade in spaced-apart relationship to one another; wherein the scraping blade planar mounting section is removably assembled to the planar blade-engaging receiving surface locating the second material edge proximate a respective end of the planar blade-engaging receiving surface and oriented with the blade edge extending forward from the scraping apparatus space block, wherein the assembly between the scraping blade planar mounting section and the planar blade-engaging receiving surface orients the scraping blade tangentially to the radius of the pressure cleaning wand; wherein the pipe connection section is configured to be connected with the pressure cleaning assembly; and wherein, during use, the spacer block maintains the planar blade between the wand nozzle and the planar work surface, the planar surface of the scraping blade is oriented tangentially to the radius of the pressure cleaning wand, and the scraping edge of the scraping blade is oriented substantially perpendicular to the longitudinal axis of the pressure cleaning wand.
