DEVICE AND METHOD FOR CHANGING CLEANING SHOE SHAKER ARM ANGLE
FIG3 is an isometric view of the detailed view of FIG2
As best shown in FIG3, the bracket 136 includes a vertical portion 140 that is fixed to the side 112 of the shoe 104, a slanted upwardly extending portion 142 that depends from the vertical portion 140, and a downwardly extending portion 144 that depends from and extends orthogonally to the slanted portion 142. The slanted upwardly extending portion 142 is oriented tangentially to the arc trajectory 'T' of the end 110 of the rocker arm 106 that is connected to the shoe 104. An acute interior angle C (FIG2) is formed between the slanted portion 142 and the vertical portion 140. The portion 142 is also slanted with respect to a horizontal plane running along the top side of the shoe 104 by an angle D. The vertical portion 140 is orthogonal to the horizontal plane. A plurality of thru-holes 146a-146d (referred to either individually or collectively as hole(s) 146) are disposed through the portion 142. The holes 146 are aligned and evenly spaced apart in a row along an axis E (FIG3) running through the center of the portion 142. The holes 146 are each sized to receive a fastener 138. Using the holes 146 and the fasteners 138, the bearing 134 may be positioned at different locations on the mounting surface 143. Holes 146a and 146c are used together as shown to receive the two fasteners 138 attached to the bearing 134 in a first location of the bearing 134. Alternatively, the holes 146b and 146d may be used together to receive the two fasteners 138 attached to the bearing 134 in a second location of the bearing 134. More holes 146 may be disposed along the length of the portion 142 providing more positioning options for the bearing 134 on the portion.

['1. A cleaning system (100) for a combine harvester having an adjustable throwing angle, the cleaning system comprising: a shoe (104) for holding a sieve of the cleaning system; a mounting surface (143) disposed on the shoe (104); and a rocker arm (106) either movably or removably connected to the mounting surface (143), characterized in that  the rocker arm (106) being configured to be mounted to the mounting surface (143) at at least two different locations on the mounting surface (143), each location resulting in a different throwing angle (A) of the shoe (104) of the cleaning system (100).']
