Portable grain handling bin

In combination,

• a batch type grain dryer including
• a frame, a plurality of wheels defining an axis of travel of the dryer and means for raising and lowering the wheels relative to the frame for supporting the frame on an underlying ground surface;
• an upright vessel on the frame having means for circulating grain in the vessel;
• means for heating grain in the vessel and evaporating moisture therefrom;
• means for circulating air through the vessel;
• means for discharging grain from the vessel;
• and
• means for delivering grain into the vessel comprising a ground supported loading hopper and a conveyor for transporting grain from the hopper into the vessel;
• and
• a portable grain bin trailer independent o the batch type grain dryer including
• a frame having a front end and a rear end, a plurality of wheels defining an axis of travel of the bin, a trailer hitch on the front frame end defining a forward path of movement of the grain bin trailer, and means for raising and lowering the wheels relative to the frame for supporting the frame on an underlying ground surface;
• an elongate bin carried by the frame and having a length dimension parallel to the axis of travel and substantially greater than a width dimension a nd a geometric center at an intersection of a centerline parallel to the length dimension and a centerline parallel to the width dimension, including
• a front end adjacent the frame front end and a rear end adjacent the frame rear end,
• an upright end wall on the rear bin end comprising the rear terminus of the trailer, and
• a bottom dump assembly located between the geometric center of the bin and the rear end of the bin, the bottom dump assembly being located immediately above the loading hopper and the first end of the bin being juxtaposed to the drying vessel, the bottom dump assembly comprising a plurality of spaced stationary slats providing a plurality of spaced first openings therebetween, a movable gate comprising a plurality of movable slats providing a plurality of spaced second openings therebetween and means for moving the gate from a first position wherein the first and second openings are aligned to a second position where the second slats close the fist openings, the first slats being triangular in cross-section having an upwardly facing apex and a horizontal base, the horizontal bases being coplanar, the second slats being coplanar and abutting the horizontal bases.

A portable grain bin comprising

• a frame, a plurality of wheels and means of raising and lowering the wheels relative to the frame;
• a bin carried by the frame and including
• first and second ends,
• a bottom dump assembly, located substantially closer to the first end than to the second end, comprising a plurality of spaced stationary first slats, triangular in cross section having upwardly facing apices and horizontal coplanar bases, providing a plurality of spaced first openings therebetween, a movable gate comprising a plurality of movable coplanar second slats abutting the first slat bases and providing ac plurality of spaced second openings therebetween and means for moving the gate from a first position where the first and second openings are aligned to a second position where the second slats close the first openings,
• a downwardly convergent bottom wall having an opening merging with the bottom dump assembly and an upper end,
• a pair of spaced upright side walls extending between the first and second bin ends and merging with the bottom wall upper rend,
• a first inclined end wall on the first bin end merging with the bottom wall upper end and defining a first angle with the vertical, and
• a second end wall on the second bin end merging with the bottom wall upper end and defining a second angle with the vertical much smaller than the first angle.
