Abstract:
A rotary combine is disclosed to include a wheel-supported main frame supporting, among other components, a cylindrically shaped rotor and a grain bin having sides and a bottom for the temporary storage of crop material treated by the combine. A support structure supported by the main frame overlying the rotor and including a lower portion having a semi-circular surface partially surrounding the upper longitudinal half of the rotor and including an upper portion having two inclined surfaces meeting to form an inverted-V shaped surface extending, in spaced-apart relationship, along and above the semi-circular surface and comprising at least a portion of the bottom surface of the grain bin.
Abstract:
For establishing proper clearance between adjacent parts of a combine harvesting machine spacers are provided which create a clearance between housing parts of the combine. The clearance produces a gap which is to be controlled in terms of its extent. To control the extent of the gap, a flap member of flexible material is used. The flap member provides for control of airflow through the machine after proper clearances are established.
Abstract:
An air cleanout system is provided for a grain unloader tube for a harvesting apparatus. The unloader tube has an auger therein and a plurality of air nozzles located at least partially within the unloader tube. The air nozzles have air outlets directed substantially longitudinally within the tube to deliver air into the tube to effect cleaning of grain and residue from the unloader tube. A pressurized air manifold is flow-connected to the plurality of air nozzles. The air nozzles comprise nozzle housings that penetrate a wall of the unloader tube, the housings having a tapered profile in an upstream direction within the tube to minimize resistance to grain flow through the tube during normal unloading operation. The nozzles are arranged longitudinally spaced apart along the tube. The nozzles of the plurality can be sequentially operated in a direction along the tube from an upstream end toward a tube outlet.
Abstract:
A cleanout configuration is provided for a grain compartment on a harvesting apparatus. The grain compartment has walls that form a trough, and a vertically arranged auger that is supported on an auger casting located in a sump at a bottom of the trough. Wall portions, in the form of a unitary casting with the auger casting are adjacent to the auger casting and comprise cleanout openings covered by removable covers. The openings are in a grate pattern. The unitary casting can be a bridge member, which supports all, or a substantial amount of the weight of the unitary casting and the auger.
Abstract:
Apparatus for lifting a cotton receiving basket of a cotton harvester above a frame thereof including a plurality of upstanding fluid lift cylinders disposed at spaced locations around the basket, each of the lift cylinders has a cylinder body including an outer surface having a vertical extent at least equal to a maximum height that the basket is to be lifted above the frame, each of the cylinder bodies being fixedly mounted to the frame and the cylinders having extendable rods attached to the basket such that when the rods are moved telescopically upwardly the basket is lifted relative to the frame; and at least one lateral support bracket fixedly mounted to the basket and engaged with the outer surface of one of the cylinder bodies for moving therealong in engagement therewith when the basket is lifted for preventing lateral movement of the basket relative to the one of the cylinder bodies.
Abstract:
A pressurized air cleaning system is provided for a harvesting apparatus having a grain tank for holding harvested crop. The cleaning system can include an air manifold and tubing network for receiving pressurized air and distributing the pressurized air to an outlet port near to the grain tank of the harvesting apparatus. The outlet port is located and configured for connecting a short portable air cleaning hose and wand to be wielded by an operator to clean the grain tank. The air manifold and tubing network can also include an outlet port near to the header, and/or next to the straw chopper, both accessible from grade level. The cleaning system can include air cleaning nozzles, fixed in position on the harvesting apparatus and connected to the network, the nozzles directing air streams onto hard-to-access areas of the harvesting apparatus. The nozzles can be located inside the grain compartment along the horizontal augers and in the unloader tube.
Abstract:
Rigid cover panels of the cover for grain storage tubes on combines, harvesting machine, are preferably fabricated of double-wall plastic to limit weight of the cover while providing desired strength and rigidity. The rigid cover panels can be pivoted about top edges of an underlying grain tank whereby the cover panels function as a height extension of the underlying tank, thus to increase the grain-carrying capacity of the tank. Flexible transition panels are preferably mounted to the rigid cover panels to bridge spaces between edge regions of the rigid cover panels when the rigid cover panels are raised to their upright, tank-extending orientations. A preferably single underlying actuator in the tank, in combination with mechanical linkages, can simultaneously raise all the rigid cover panels, all the flexible transition panels, and the discharge end of a clean grain elevator which discharges grain into the tank.
Abstract:
A folding door or gate arrangement and method of operation thereof for a mobile cotton harvesting machine including a tiltable cotton module builder. In one embodiment, folding door or gate arrangement includes primary and secondary folding door segment pivotal between a folded or closed position in at least partially closing relation to an open end of the module builder and an unfolded or open position at least substantially parallel to a floor thereof, and a door driver arrangement connected between the primary door segment and the secondary door segment including a pivoting link element that facilitates pivotally moving the secondary door segment while the module builder is pivoted to an unloading position without exerting binding or potentially damaging loads against the door segments or the drivers to provide a straight inclined path for unloading or loading cotton onto of from a surface lower than the module builder. Folding door arrangements are also disclosed which work in concert with rearward movement and tilting of the of module builder.
