Apparatus for painting an ice surface of rink

摘要

Apparatus for spraying an ice surface with a white paint comprises a trailer having a tank carried on the trailer, a pump and a boom having a plurality of spray nozzles. The tank has a large opening in the top for receiving bags of paint pigment. The pump is a high capacity pump which generates a flow rate significantly greater than necessary to supply the nozzles. The excess is returned to the tank through a jet mixing system including four arms each having a pair of jet nozzles. A mixing wand is also provided which receives mixed materials from the pump for the jet nozzle for stirring within the tank. The nozzles are closely spaced so as to generate an overlapping spray pattern. The nozzles generate a fine mist and are directed slightly upwardly and rearwardly.
