Abstract
A machine for spraying a liquid for the treatment of plants and soils includes a nozzle fed by a pump and a pipe. The nozzle projects the liquid to be sprayed against the central portion of a rotary thrower. A collector in the form of a sector of a ring is fixed along the periphery of the rotary thrower without contact with it, so as to intercept the liquid projected except within an angle .theta.. The liquid intercepted by the collector is collected in a receiver and returned to the tank of the machine.
