DEVICE AND METHOD FOR CHANGING CLEANING SHOE SHAKER ARM ANGLE
FIG6 depicts a side elevation view of a cleaning system of a combine according to yet another alternative embodiment
FIG6 depicts a fourth exemplary embodiment of a cleaning system. The fourth embodiment is substantially similar to the first embodiment with the exception that the bracket 136 is omitted and replaced by a series of holes 600 (e.g., six holes) that are disposed in the side 112 of the shoe 104. The holes 600 are aligned along the arc trajectory 'T' of the end 110 of the rocker arm 106. In use, the end 110 of the rocker arm 106 could be mounted to two of those six holes 600 using fasteners 138 such that the throwing angle A of the rocker arm 106 is maintained at the first predetermined angle. Alternatively, the end 110 of the rocker arm 106 could be mounted to two different holes of the six holes 600 such that the throwing angle A of the rocker arm 106 is maintained at the second predetermined angle.

['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).', '3. The cleaning system of claim 1 or 2,  characterized in that  the rocker arm (106) includes two opposed ends (108, 110), one opposed end (110) being releasably connected to the mounting surface (143), and the other opposed end (108) being connected to a fixed point on the combine harvester.']
