FIELD: agriculture.

SUBSTANCE: devices for agricultural spraying. The lid (10) is designed to seal the opening (101) of the container (100), which is defined by the edge (102) of the opening. The cover (10) includes an air channel (11) containing a first hole (12) centred on a first axis (15) in an axial direction and for communicating with the interior of the container (100) on a first side (16) of the first hole (12) along first axis (15). The first hole (12) further includes a hole edge (17) forming a valve seat (18) on the first side (16) of the first hole (12). The air channel also contains at least one second hole (13), through which the first hole (12) is configured to communicate with the external space of the container (100) on the second side (19) of the first hole (12), which is located opposite the first side (16) along the first axis (15), the float (14), configured to move, by floating on the surface of the liquid contained in the container (100), from the opening position to the closing position of the first hole (12), in which the float (14) pressed against the valve seat (18), with the float (14) thus forming a valve. The air passage (11) further includes at least one damper (20) through which the first hole (12) and the second hole(s) (13) communicate with each other on the second side (19) of the first hole (12). The system for equipping an agricultural machine contains a container (100) for a liquid, such as a plant protection product or liquid fertilizer, and the above-described cover (10).
