<p>The atomiser (1) comprises a tank (3) and a driven shaft (2) turned by a motor or a power take-off and mechanically connected to a pump (4), which in turn is hydraulically connected with a plurality of nozzles (5) dispensing a liquid substance for spraying on cultivations. The driven shaft (2) is also connected to an overgear (7) which is in mechanical transmission with a turbine (6) for atomising the liquid substance. The overgear (7) internally exhibits a plurality of gears (9) and includes means for engaging (8, 8', 8") for setting up a pre-engagement of gears defined by contact of a gear with another gear, each gear being part of a plurality of gears (9). Elastic means (10) are included for achieving an automatic engagement of gears, defined by an enmeshing of a gear with another gear, both gears being part of the plurality of gears (9).</p> |
