Retractable spray shield for agricultural use

In combination, an agricultural spray machine, an agricultural spray boom, and a retractable spray shield for agricultural use,

• the agricultural spray machine having:
• a drive train;
• a liquid tank;
• and
• a pump receiving a liquid held within said liquid tank;
• the agricultural spray boom having:
• a boom arm extending at least in part in a direction transverse to a forward direction of travel of said agricultural spray machine;
• and
• at least one spray nozzle suspended from said boom arm and in fluid communication with said pump;
• the retractable spray shield for agricultural use having:
• a liquid barrier film;
• a storage tube configured to receive and store said spray shield, said storage tube having
• a storage tube bottom and a storage tube length, said storage tube length defining a storage tube longitudinal axis,
• a unit holder having a length defining a unit holder longitudinal axis parallel to said storage tube longitudinal axis, said unit holder supporting said liquid barrier film, and
• a pintle defining an axis of rotation transverse to said storage tube longitudinal axis and coupling said unit holder to said storage tube, said pintle configured to allow said unit holder to pivot about said pintle relative to said storage tube;
• at least one strain relief spring opposing rotation of said unit holder about said pintle relative to said storage tube;
• a deployment drive rotating said liquid barrier film relative to said storage tube between a first stored position adjacent to said storage tube and a second deployed position more perpendicular to said storage tube;
• and
• a boom arm coupler adapted to couple said retractable spray shield to said agricultural spray boom and simultaneously locate said liquid barrier film adjacent to and in a spray pattern of said at least one spray nozzle when said liquid barrier film is in said second deployed position.
