ABSTRACT:
A grain cup for use with the conveyor belt of a grain elevator includes two oppositely disposed, flat side panels which are perpendicularly joined with a flat rear panel. Joined between the two side panels and extending upwardly from the base of the rear panel is a forward panel which has two separately curved portions. A first portion is of a part-cylindrical shape having a constant curvature about a first axis and the forward panel includes a leading edge having a constant curvature about a second axis. The second portion is also part-cylindrical and has a constant curvature about a third axis. This third axis being at an acute angle relative to the first axis. The grain cup is fabricated as a single integral member out of polyethylene and includes a series of vent holes in the leading panel and adjacent the rear panel for facilitating the scooping of grain into the cup.
