Seed treater and conveying apparatus

An apparatus for simultaneously conveying seed and applying

• a liquid chemical treatment to it, comprising, in combination,
• an elongated auger tube having opposite inlet and discharge ends, seed supply means adjacent the inlet end thereof, an applicator opening through said tube at a position spaced downstream from said seed supply means and an auger rotatably supported therein, said auger comprising an elongated center shaft and brush flighting extending outwardly from said center shaft,
• an applicator for depositing liquid chemical treatment on the seed conveyed through the auger tube, said applicator comprising,
• an upright tank having a discharge opening at the lower end thereof,
• means for supporting said tank relative to said auger tube such that said discharge opening is in communication with said applicator opening,
• a first valve means between said discharge opening of said upright tank and said auger tube for regulating the flow of liquid chemical into said auger tube,
• a second electrically controlled valve means between said discharge opening of said upright tank and said auger tube which is normally closed but which is opened upon the actuation of said auger,
• selectively actuatable motor means operably connected to said auger for rotating said auger;
• said second valve means being electrically connected to said motor means so as to open upon actuation of said motor and so as to close upon deactivation of said motor.
