Abstract
A grain cleaner is taught including features for facilitating maintenance and repair of the cleaner over previous grain cleaners. In particular, the 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.
Claims38
A grain cleaner comprising a main 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 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.
A grain cleaner comprising a main 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 permit flow of the grain away from the grain cleaning means, at least at least a portion of the grain cleaning means being mounted on a support frame moveably mounted to the main framework such that the grain cleaning means can be moveable between a first position and a second position on the main framework of the grain cleaner.
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, an auger being disposed in the grain outlet, the auger including a trough and an auger, the trough being mounted to permit the trough to be pivoted to empty its contents by gravity.
A grain cleaner comprising a framework, a grain inlet, a screen separator drum having a long axis and supported by the framework to be rotatable about its long axis, a channel extending to conduct materials from the screen separator drum to an indent cylinder assembly, the indent cylinder assembly having a long axis and including an indent cylinder and an auger flight extending therethrough, the indent cylinder and auger flight being supported by the framework and the cylinder being rotatable about the long axis of the assembly and a grain outlet to conduct materials away from the auger flight, a second auger flight being disposed in the grain outlet, the second auger flight including a trough and an auger, the trough being mounted to permit it to be pivoted to empty its contents by gravity.
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 at least one indent cylinder assembly, the indent cylinder assembly including an indent cylinder having an inner surface formed with a plurality of indentations formed thereon, the indent cylinder being formed of a sheet of material wrapped and releasably secured into a cylindrical form and mounted about an inner frame.
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 including a grain inlet for permitting a flow of grain into the air separator box, a grain outlet positioned below the grain inlet such that 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 at the flow of grain between the grain inlet and the grain outlet, a waste material outlet from the air box and a baffle positioned between the grain outlet and the waste material outlet.
