Abstract
The invention relates to a device for spraying a sprayable product on plants which includes turbine having a substantially vertical axis, preferably disposed between the side frames of a chassis, which conveys air via a channel that passes under a reservoir of sprayable product to emerge behind the latter via a horizontal outlet or a vertical outlet. Energy loss due to a change in direction of the air is thus minimized and yet very simple and lightweight mechanisms for driving the turbine are obtained.
