PROBLEM TO BE SOLVED: To provide a self-propelled multi-purpose work device which gathers pebbles and other foreign matter or performs a cleaning operation on a sediment surface while moving on the sediment surface in a banker of a golf course, in an open space or a sand pool of a park, a school, etc., at a beach or riverbed, in an open space of a ground, in a farm, and so on.SOLUTION: A self-propelled multi-purpose work device includes: a swing sieve body 1 which sieves sand to collect pebbles and other foreign matter. A swing sieve body 1 has a blade body 3 for scooping sand in a banker at a tip edge in a moving direction and also has a reservoir 4 for pebbles and other foreign matter at a rear edge in the moving direction. The self-propelled multi-purpose work device includes: a support structure 6 which is positioned in front of a power work vehicle 5 and supports the swing sieve body 1 in a free swing state; and an eccentric driving structure 15 which receives power from the power work vehicle 5 to swing the swing sieve body 1. The swing sieve body 1 freely rolls on the power work vehicle 5 around a rolling fulcrum as a shaft center and can freely roll in such an attitude that the swing sieve body 1 is lowered on a sediment surface, and includes an attitude control mechanism which holds the swing sieve body 1 in a horizontal attitude above the sediment surface. |
