Abstract:
1. A hand-held device for opening and closing a discharge door, having an inner end, an outer end, and opposite sides, which is horizontally slidably mounted at the lower end of a bulk seed box with the seed box having an opening formed therein at each of the opposite sides of the discharge door adjacent the outer end thereof, the discharge door being movable between closed and open positions, comprising: a horizontally disposed generally U-shaped frame having an elongated base portion with horizontally spaced-apart first and second legs extending from the opposite ends of said base portion; each of said legs having free ends spaced from said base portion; said free ends of said legs adapted to be inserted into the openings on the seed box at the sides of the sliding discharge door; a selectively operable spreader mechanism secured to and extending between said legs adjacent said free ends thereof; an electrically powered screw actuator mechanism mounted on said frame which includes an actuator rod which is parallel to said legs and which is movable between extended and retracted positions; said actuator rod having an outer end; and discharge door engagement structure at said outer end of said actuator rod for selective engagement with the outer end of the discharge door whereby retraction of said actuator rod will cause the discharge door to be slidably moved to said open position and so that extension of said actuator rod will cause the discharge door to be moved to said closed position.
