TRUCK TIRE WASHER COMPOSED OF HYDRO-BLASTING AND SPRAY NOZZLES

摘要

A truck tire washer composed of hydro-blasting and spray nozzles is provided to wash off dirt adhered on the tire with increased spraying power by blasting water which contains compressed air to the surface of the tire, using the conventional water spray washing method as well. A main piping(WP1,WP2,WP3) and a plurality of branch pipes(WP4) are arranged to an underwater pump(21) installed within a pit(P) of a truck tire washer, in suitable intervals from the center of the tire washer towards a tire(01) for the supply of wash water(W) and air, wherein a hydro-blaster(33) is assembled at the end of the branch pipes. A compressor(31) and an air tank(32) are installed around the tire washer, connecting air pipes(AP1,AP2,AP3) and branch pipes(AP4) of the blaster. The hydro-blaster allows a connector nipple of a water hose and a connector nipple of an air hose to be joined, forming an acute angle, so that the surface of the tire is hit by the wash water by an ejector effect created by high-speed compressed air. A conventional tire washer of water spray type is used as well with a lateral water spray pipe(22) installed between a longitudinal water spray pipe on the left and right sides of tire washer connected to the underwater pump, and rollers.
