摘要： In a combine harvester, an array of ground engaging skid shoes or feelers spans the header platform and is divided into right- and left-hand groups, each group associated with a position sensor switch. Each switch transmits to an electrohydraulic control system, a signal representative of the relative position of the skid shoe closest to the ground in its half of the platform. The combined left- and/or right-hand signals are transduced to control platform vertical adjustment and lateral tilt automatically. In one embodiment, a pair of lift cylinders, acting in unison, control platform elevation while a third cylinder is dedicated to tilt control. In other embodiments, paired lift cylinders are controllable independently, to provide both height and tilt control. Supporting the feeder conveyor lower shaft and the header main drive shaft in the laterally pivotable lower forward portion of the feederhouse permits direct transfer of crop material from the platform auger to the feederhouse conveyor and also simplifies header drive arrangements.

摘要： A combine has a feeding system, for conveying crop material from a harvesting unit to the infeed rotor of a longitudinal axial flow rotary crop processing unit, including a feeder house employing a pair of augers, mounted side by side in an enclosed housing, and contrarotating at a relatively high speed. The augers are cantilevered from a bulkhead at the inlet end of the feeder house and do not make contact with the housing. The housing cross section does not conform to the cylindrical surfaces swept by the augers and there is also space between the augers themselves so that heterogeneous material can be conveyed within the housing on all sides of the augers. Housing shape and clearances are designed so that there is a minimum of dead space in the housing and, with some assistance from fixed strippers, mounted inside the housing parallel to the axes of the augers, material is conveyed generally linearly at a speed nearly equal to the equivalent axial speed of the auger flighting. A transition housing, between the feeder house and infeed rotor casing, is shaped to minimize dead space at the point of transfer from the feeder house augers to the infeed rotor, so that the moving elements (augers and rotor) do not lose control of the material being conveyed. A feeder beater is used at the feeder house throat to strip material from the harvesting unit cross auger and assist in accelerating it in the feeder house.

摘要： In an axial flow rotary separator for a combine, radially extending spike-tooth-like blades are arranged on a rotor body in "reverse" helical arrays, that is, such that helical flighting, similarly disposed, would tend to convey crop material upstream. The helix angles defined by the arrays approximate that of the mean spiral path of conveyance of a crop material mat portion through the separator housing. Propulsion of the crop material mat thus results from a plurality of spaced and staggered engagements of small contact area. The arrays are spaced so that the rotor elements present no extensive wall or front to the crop material thus reducing the tendency to "roping" and separator plugging in tough straw conditions.
摘要翻译： 在用于组合的轴向流旋转分离器中，径向延伸的棘齿状叶片以“反向”螺旋阵列布置在转子体上，也就是说，类似地设置的螺旋形飞行倾向于将作物材料向上运送。 由阵列限定的螺旋角度近似于通过分离器壳体的作物材料垫部分的输送的平均螺旋路径的螺旋角度。 因此，作物材料垫的推进是由多个间隔开和交错的接触面积小的接合产生的。 阵列是间隔开的，使得转子元件没有对作物材料没有广泛的壁或前部，因此减少了在困难的秸秆条件下“卷曲”和分离器堵塞的倾向。

摘要： A row crop harvesting header has a main frame with a plurality of forwardly extending, independently vertically adjustable row units mounted on the frame, each row unit including a frame attached to the header frame at its rearward end and a ground engaging skid at its forward end. A pair of endless flexible conveyors are mounted on the row unit frame and have opposite, rearwardly moving, upwardly and rearwardly inclined inner runs adapted to engage the stalks of row planted crops as the machine advances and convey it rearwardly, a cutting apparatus below the forward inlet ends of the belts severing the crop material from the field as it is engaged by the conveyor. The row unit frame includes a pair of forwardly diverging members extending forwardly of the front of the conveyors to form a crop receiving throat in front of the inlet to the conveyors, and a pair of rock deflectors are attached to the opposite frame elements and include a plurality of generally fore and aft fingers disposed in the throat area, the opposite sets of fingers being laterally spaced to provide a fore and aft passage that is wide enough to permit the passage of the crop material to the conveyors but deflects larger rocks and foreign objects downwardly or causes the row unit to ride up over said objects to prevent damage to the cutting apparatus or ingestion of the objects into the conveyors.

摘要： In a rotary separator, cylindrical threshing, frusto-conical separating, and centrifugal fan sections are arranged coaxially and in tandem. A fixed grate including threshing and separating portions surrounds and generally conforms to a rotor profile. A frusto-conical collector housing encloses the forward part of the separator and feeds threshed and separated grain to a grain cleaning unit, the screen elements of which, along with the collector housing, rotate concentricaly with the grate while at the same time reciprocating axially. A stationary cylindrical housing surrounds the cleaner unit and clean grain and tailings pass centrifugally from the cleaner screens to separate annular channels, to be swept around the inside of the housing by paddles moving with the cleaner elements to tangential discharge points near the top of the separator for transfer to clean grain and tailings return augers respectively. The centrifugal fan draws air approximately axially through the cleaner unit removing chaff and other light material and also receives straw carried over the grate, for discharge downwards from the fan housing.

摘要： The feeder house of a self-propelled combine harvester carries a front-mounted gatherer which delivers crop material to a forward inlet of the feeder house which is pivotally supported by the combine separator body, and delivers crop material to an inlet of the separator. A pair of side-by-side, contra-rotating auger conveyors deliver crop material directly to the separator rotor in a relatively concentrated high-speed stream. Convergence and concentration of the harvested crop material begun by a grain platform auger is continued by a pair of transverse beaters, each including helical conveying elements, arranged in tandem ahead of and partially above the dual auger conveyors. A forward beater close to the feeder house inlet receives material directly from the platform auger and conveys it rearwardly over a floor somewhat elevated with respect to the auger conveyors and transfers it to a second beater above the forward end of the dual augers which directs it downwards into the auger conveyors. A hold-down rod, generally parallel to the axis of the conveyor augers, is provided above each auger to assist in controlling the transfer of crop material from the rear beater to the augers. Portions of the feeder house also playing an important part in the control and conveying of crop material include the floor beneath the first beater, converging ramp-like surfaces in the feeder house side walls downstream of the rear beater, and the particular spacing from the auger conveyors of the feeder housing wall portions surrounding them.

摘要： The axial flow rotary separator of a combine includes a rotor having a generally cylindrical threshing section surrounded by a fixed, non-adjustable concave or grate so as to define an annular threshing space. The rotor includes threshing bar assemblies pivoted about axes parallel to the rotor axis and spring loaded in the direction of reducing concave clearance, against adjustable stops. Setting of the stops is controlled by adjusting eyebolts mounted on the front of the rotor, accessible from the front of the combine and connected to the stops through a pivot arm assembly. In normal operation springs hold the threshing bar assemblies against the stops but the pressure of a large foreign body or an excessive flow or material entering the threshing space may overcome the spring pressure forcing the threshing bars to retract to provide necessary clearance.
