A device for sweeping volcanic ash on lawn was designed and its capability has been tested. This lawn sweeper was installed above a conveyor belt on which artificial lawn was pasted. The ash was uniformly scattered on the lawn using a hopper, conveyed at a constant velocity to the lawn sweeper and swept by it. The lawn sweeper is composed of small air jets and an air flow in a channel above the lawn. The former lift up the volcanic ash from the lawn and the latter conveys it to the dust collector. In these experiments, the lawn velocity, i. e., scavenging speed, the velocity of air flow in the channel, the air jet velocity and the arrangement of the blow tubes are altered, and the rates of collection are examined. The effect of these conditions on the rates of collection, and the optimal conditions for a high rate of collection and uniform scavenging are clarified.
