WEEDER

摘要

PROBLEM TO BE SOLVED: To provide a weeder capable of effectively weeding by injecting superheated steam and high-temperature combustion exhaust gas from the tip of a steam-injecting hose. SOLUTION: This weeder has a movable body 2 which is integrally formed from a water tank 4 and a boiler 5 for generating the steam. The steam- injecting hose 3 is attached to the boiler 5 of the movable body 2. The steam- injecting hose 3 has a double-cylinder structure comprising an inner cylinder and an outer cylinder so that the superheated steam is injected from the tip of the inner cylinder and the high-temperature combustion exhaust gas is injected from the tip of the outer cylinder.
