Seed transporter
A seed transporter for transporting seeds in their seed boxes having a frame with an upper surface for supporting the seed box. The frame has upstanding members that extend upwardly from the frame and are adapted for contacting opposite sides of the seed box and for restraining movement of the seed box when the seed box is located between the upstanding members. The upstanding members include a draw bar that is slidingly retained within the upstanding members. The draw bar includes a catch affixed to the draw bar adapted for catching a retention surface on the seed box. The draw bar is movable between a first and second position. The first position locates the catch above the retention surface and the second position locates the catch beyond the retention surface on the box.
1. A seed transporter for transporting seed boxes, said seed transporter comprising: a frame having an upper surface for supporting one of said seed boxes, said frame including upstanding members extending upwardly of said frame, said upstanding members adapted for contacting opposite sides of said seed box and restraining movement of said seed box when said seed box is located between said upstanding members, wherein two of said upstanding members are aligned laterally to form a pair and include a draw bar slidingly retained within said pair of upstanding members, said draw bar including a catch affixed to said draw bar and adapted for catching a retention surface on said box, said retention surface extending for a portion of sides of said box, said catch adjacent to said retention surface when said box is between ones of said upstanding members, said draw bar having a first position locating said catch above said retention surface and said draw bar being slidable to a second position which positions said catch laterally beyond said retention surface on said box.
2. A seed transporter as claimed in claim 1 , wherein guides are oppositely located from each other spaced transversely from said upstanding members and being adopted for locating said box in a traverse direction.
3. A seed transporter as claimed in claim 2 , wherein said draw bar is held within apertures in each of said pair of upstanding members through which said draw bar passes, said draw bar having a complementary shape to said apertures so that said draw bar is fixed from rotation.
4. A seed transporter as claimed in claim 3 , wherein said draw bar include a spring for biasing said draw bar into said second position.
5. A seed transporter as claimed in claim 4 , wherein said draw bar includes a locking mechanism for locking said draw bar into first position.
6. A seed transporter as claimed in claim 5 , wherein said locking mechanism comprises an aperture located on said draw bar and an aperture located on said frame, said apertures on said draw bar and on said frame being aligned when said draw bar is in its first position, said apertures on said draw bar and on said frame adapted for receiving a pin upon alignment thereby locking said draw bar in said first position.
7. A seed transporter as claimed in claim 6 , further comprising a discharge chute located within said upper surface and adapted for communication of agricultural product from said box to a location below said upper surface.
8. A seed transporter as claimed in claim 6 , further comprising a second pair of said upstanding members including a second drawbar slidably retained therein, said second drawbar including a second catch affixed to said second drawbar and adapted for catching a second retention surface on said box, said second drawbar being slidable between a first position in which said second catch is located above said second retention surface on said box and a second position which positions said second catch laterally beyond said second retention surface on said box.
9. A seed transporter as claimed in claim 7 , further comprising a second pair of said upstanding members including a second drawbar slidably retained therein, said second drawbar including a second catch affixed to said second drawbar and adapted for catching a second retention surface on said box, said second drawbar being slidable between a first position in which said second catch is located above said second retention surface on said box and a second position which positions said second catch laterally beyond said second retention surface on said box.
