Concrete mold cleaning machine for e.g. concrete block, has units to displace high pressure fluid projection unit or support unit in plane, where projection unit has nozzle projecting fluid in direction forming non zero angle with plane

摘要

The machine has a support unit (4) to store a mold, and a projection unit (5) to project a high pressure fluid on the mold. Displacement units (6, 7) displace the projection unit or support unit in a plane. The projection unit has a nozzle (9) projecting the fluid in a direction forming a non zero angle with the plane. A unit changes the orientation of the projection direction of the nozzle.
