PURPOSE: A grain conveyer tank is provided to adjust the proper discharge amount of grain through a discharge unit by simplifying the structure. CONSTITUTION: A grain conveyer tank consists of: a grain storage unit(2) for storing grain; a grain conveyer having a conveyer screw lengthwise in the grain storage unit; a triangular plate mounted along the conveyer screw to induce grain dropping to the conveyer screw; a discharge unit for discharging the grain on the conveyer screw; and legs(17) supporting the grain storage unit. A rotatable shaft is mounted on the triangular plate rotatably. Pinion gears(12) are fixed to both ends of the rotatable shaft to convert rotation of the rotatable shaft into vertical motion of the triangular plate. A couple of rack gears(13,13a) are engaged with both sides of the pinion gear to induce rotation of the pinion gear into vertical rectilinear motion of the rotatable shaft. Guide grooves(14) are formed on the grain conveyer tank body to move the pinion gears vertically following the rack gears. Guide rails(15,15a) are attached to the grain conveyer tank, and tracks(16,16a) are formed to slide horizontally along the guide rails. Hydraulic jacks(18) lift up or down the grain conveyer tank. The discharge amount of grain is adjusted artificially at a safe position.
