Sorting cylinder for seeds and other grains
First Claim
1. A sorting cylinder for seeds and other grains, comprising:
- a horizontal calibrating cylinder;
first, second, third and fourth supporting rolls for supporting said calibrating cylinder, said first and second rolls being arranged on opposite ends of said calibrating cylinder;
a stationary machine casing surrounding said calibrating cylinder, said casing having a longitudinal side, an inlet for receiving material to be sorted and means for leading off fractions thereof and a detachable longitudinal side wall wherein said calibrating cylinder further comprises a running ring and a driving ring, said driving ring having a circumferential keyway at an end on a driving side thereof and wherein said fourth supporting roll further comprises a driving wheel frictionally engaged with said keyway, said driving wheel having a correspondingly wedge-shaped profile for enabling the calibrating cylinder to be freely lifted off upwardly and to be mounted and dismounted through said longitudinal side of said machine casing wherein said driving ring has a laterally disposed circular-cylindrical running surface and said first supporting roll is arranged on the driving side and has a circular-cylindrical supporting surface such that the running surface rests on said first supporting roll;
a cleaning device for cleaning said calibrating cylinder wherein said calibrating cylinder and said cleaning device utilize said driving ring as a joint driving element and wherein said cleaning device further comprises a transmission wheel having a corresponding wedge profile for cooperative engagement with said running wheel;
U-shaped guide means fastened to said machine casing and within which said cleaning device is guided in a displaceable manner relative to said calibrating cylinder; and
sliding means located on first and second ends of said cleaning device and which is inserted into said guiding means.

Abstract
A sorting cylinder for seeds and other grains with a horizontal, driven calibrating cylinder (11) resting on rolls (22, 23, 24, 25) and with a stationary machine casing (1) surrounding the calibrating cylinder (11) which has an inlet (4) for the material to be sorted and a mechanism (5, 6, 7) to lead off the fractions as well as a detachable longitudinal side wall (41, 42). In order to simplify storage and to facilitate the exchangeability also for untrained operating personnel, the calibrating cylinder (11) freely rests on four supporting rolls (22, 23, 24, 25) and at least one of the four supporting rolls (24; 25) is designed as a driving wheel (25). The calibrating cylinder (11) can be freely lifted off towards the top or can be mounted and dismounted through a longitudinal side (41, 42) of the machine casing (1).
