Abstract
A grain cleaner has an indent cylinder assembly which includes a removable cylinder. The cylinder is removed by unwrapping it from around a frame. The grain cleaner also includes at least some augers with drop away troughs. The grain cleaner also includes grain cleaning assemblies such as, for example, indent cylinders and rotary screen drums and/or grain cleaning assemblies drive systems which are mounted on framework members capable of pivoting outwardly from the machine allowing access to machinery and components positioned centrally within the grain cleaner.
Claims15
A grain cleaner comprising:
- a framework, a grain inlet for accepting a flow of grain, grain cleaning means to separate the grain from at least some of its contaminants and a grain outlet to conduct the grain away from the grain cleaning means, the grain cleaning means including an air separator box having a grain inlet for permitting a flow of grain into the air separator box, the grain inlet formed to distribute the flow of grain into a thin curtain, a grain outlet positioned below the grain inlet such that the flow of grain passing from the grain inlet can drop, by gravity, into the grain outlet, a means for generating a flow of air and directing it toward the flow of grain between the grain inlet and the grain outlet, the means for generating being adjustable to select the direction of the flow of air acting on the flow of grain, a waste material outlet from the air box, the waste material outlet positioned such that the flow of air can pass into the waste material outlet without passing again through the flow of grain and a baffle positioned between the grain outlet and the waste material outlet, the baffle being adjustable in its degree of extension into the air separator box.
A grain cleaner comprising:
- a framework, a grain inlet for accepting a flow of grain, grain cleaning means to separate the grain from at least some of its contaminants and a grain outlet to conduct the grain away from the grain cleaning means, the grain cleaning means including (a) an air separator box having a grain inlet for permitting a flow of grain into the air separator box, a grain outlet positioned below the grain inlet such that the flow of grain passing from the grain inlet can drop, by gravity, into the grain outlet, a means for generating a flow of air and directing it toward the flow of grain between the grain inlet and the grain outlet, a waste material outlet from the air box, the waste material outlet positioned such that the flow of air can pass into the waste material outlet without passing again through the flow of grain and a baffle positioned between the grain outlet and the waste material outlet;
- (b) a scalper having a tube rotatable along its long axis and including apertures disposed through its side wall, the apertures being selected to permit passage therethrough of the grain while excluding materials of size larger than the apertures and a grain hopper for directing the flow of grain against the tube's outer surface, the hopper including a wall positioned against the outer surface of the tube, the flow of grain being retained in the hopper between the wall and the outer surface of the tube until it passes through the apertures of the tube and (c) a chute extending from the scalper and converging with the waste material outlet to convey excluded materials from the scalper to the waste material outlet, the chute opening into the waste material outlet in such a way that the flow of air passing through the waste material outlet creates a vacuum in the chute and draws air from the scalper into the waste material outlet.
