PROBLEM TO BE SOLVED: To enable spraying on a wide area with a high degree of freedom of spray direction, at the same time eliminating burdens and risks for a worker and ensuring stable quality of a finished sprayed surface, without relying on a skill of the worker.SOLUTION: A slope surface spray device S includes: a tilting part R3 for tilting an intermediate arm 4 relative to a boom 2; a rotary part R4 for rotating a distal arm 6 around an axis X1; a rotary part R5 for rotating the distal arm 6 around an axis X2 tilted from the axis X1 by an angle α; an expansion/contraction part R6 for expanding/contracting the distal arm 6; a tilting part R7 for tilting the distal arm; a tilting part R8 for tilting a spray direction of a nozzle 8 around an axis X3; a rotary part R9 for rotating the spray direction of the nozzle 8 around an axis X4 orthogonal to the axis x3; and a tilting part R10 for tilting the spray direction of the nozzle 8 around an axis X5 parallel to the axis X3.SELECTED DRAWING: Figure 1 |
