ABSTRACT:
A method for harvesting, transporting and storing grain utilizes small readily moved containers or bins in combination with a specially designed trailer mechanism to allow grain to be readily stored, as it is harvested, at the harvest site and then at a more convenient time transported to the place of ultimate use, sale or to centralized storage. The method utilizes a compact bin which may be stored in the field and yet be safe from weather and vermin, which may utilize additional drying mechanisms or which may utilize air drying of the grain. The bin is mounted on two permanent I-beam rails which are designed to mesh with roller trucks on a specially designed pick-up trailer. The pick-up trailer utilizes a frame having rails on which the roller trunks are carried. The trailer has a hydraulic lift mechanism to tilt the trailer to engage the leading edge of the I-beams of the bin to tilt the bin so that it can be self-loaded onto the trailer by backing the trailer underneath the bin. Guide mechanisms on the trailer centrally position the bin and the rails of the bin over the roller trucks carried by the trailer rails. A centering mechanism on the trucks also assists in correctly aligning the bin rails and the trucks. When the bin is loaded on the trailer, the trailer is lowered to the horizontal position with the bin loaded on the top of the trailer. Self latching mechanisms on the trailer engages the back edge of the bin I-beams to prevent the bin from sliding off the trailer when the trailer is in the horizontal position. Front stop mechanisms on the trailer prevent the forward motion of the bins once they have been loaded.
