ABSTRACT:
A grain turner (101)of the present invention is adapted for use with a grain dryer having an inner dryer wall (7) and an outer dryer wall (9) spaced therefrom and defining a vertically extending grain path (11) therebetween. A grain turner (101) of the present invention is disposed within the grain path for exchanging (turning) grain from the inner portion of the grain path to the outer portion of the grain path and vice versa and for exchanging grain widthwise within the grain path. The grain turner comprises a vertical wall (109) disposed between the inner and outer dryer walls. The grain turner further has at least one pair inclined plates (119, 125) with one of the plates (119) being on the inside of the vertical wall and with the other of the inclined plates (125) being on the outside of the vertical wall. Plate (119) is inclined downwardly in a first widthwise direction and the other of the inclined plates is inclined downwardly in the opposite widthwise direction. The lower end of the first inclined plate (119) extends downwardly and outwardly so as to deliver grain flowing downwardly thereon to a location within the grain path substantially beneath the second inclined plate (125). The lower end of inclined plate (125) extends downwardly and inwardly so as to deliver grain to a location within the grain path substantially beneath the first inclined plate. In this manner, the grain flowing down the first inclined plate is turned from the inside to the outside of the grain path and the grain flowing down the second inclined plate is turned from the outside to the inside of the grain path. Further, the grain flowing down the inclined plates is rotated about a substantially vertical axis within the grain path so as to effect the widthwise exchange of grain from one width location to another as the grain is turned.
A method of turning grain is also disclosed.
