摘要： In a combine harvester, a microprocessor controls the adjustment of the cleaning sieve or sieves and/or chaffer sieve or sieves in response to information keyed into a keyboard by the combine operator. If the actual setting of a device (sieve or chaffer) is greater than the desired setting the device is first fully opened and maintained in that position for a predetermined period of time to allow foreign objects and crop material to clear itself from the device by normal combine operation. This avoids damage to the control linkage, sieve slats, and so forth. After the device is fully opened and maintained open for the predetermined interval of time it then closes beyond the desired setting by some predetermined amount after which the device is opened to the desired setting. This arrangement insures that the approach to the final adjustment is always made as the device is being opened, thereby allowing for compensation of play or backlash in the mechanical linkages which adjust the device.

摘要： An axial flow combine having a forward elevating conveyor leading to the feeder house in which beating rotors coact with stationary concave grates and also includes augers on the forward ends of the rotors to insure positive feed of crop material from the elevating conveyor to the rotors. The invention includes feed divider vanes extending in the direction of feed of the crop material from the elevating conveyor to the rotors and are fixedly positioned upon a ramp extending beneath the augers to divide the oncoming material fed to each auger into two streams to minimize the tendency for the material, such as tough long straw experienced in rice, to be formed into spiral rope-like configurations incident to being transformed from linear feed direction by the elevating conveyor to lateral spiral motion, caused by the augers, for delivery between the rotors and grates for threshing the material.

摘要： A cleaning apparatus for a combine harvester is disclosed wherein the grain pan and chaffer sieve are mounted for pivotal leveling movement about both a transversely extending axis and a longitudinally extending axis. The grain pan and chaffer sieve are mounted in a subframe pivotally supported by a shaker shoe such that the subframe is pivotable about a longitudinally extending axis relative to the shaker shoe, which in turn is pivotally supported on the combine main frame for pivotal movement about a transversely extending axis. A pair of inclinometers disposed to sense the inclination of the combine are utilized to control the flow of hydraulic fluid to hydraulic actuators arranged to pivotally move the shaker shoe and the subframe in response to a sensing of a non-horizontal inclination by the inclinometers. A combination of the fore-and-aft and transverse pivotal movements permits the grain pan and chaffer sieve to be maintained in an overall horizontal orientation irrespective of the attitude of the combine main frame.

摘要： A cleaning apparatus for a combine harvester is disclosed wherein the grain pan and chaffer sieve are mounted in a subframe pivotally supported by a shaker shoe for a laterally tilting movement about a fore-and-aft extending axis. The shaker shoe is connected to an eccentric drive to effect a generally fore-and-aft shaking action to convey threshed grain thereon in a rearward direction. The pivotal movement of the subframe relative to the shaker shoe is accomplished through the use of a hydraulic cylinder interconnecting the shaker shoe and the subframe to permit a lateral leveling of the grain pan and chaffer sieve when the combine is operated under sidehill conditions. An inclinometer is utilized to control the flow of hydraulic fluid to the hydraulic cylinder to permit the subframe to be leveled in response to a sensing of a non-horizontal transverse inclination by the inclinometer.

摘要： The adjustment of operating parameters such as the sieve opening, concave opening, chaffer opening, rotor speed and/or fan speed is/are accomplished under the control of a microprocessor operating in response to the striking of keys on a keyboard. The combine harvester operator may select a particular parameter for adjustment by striking a key corresponding to that parameter. The desired setting of the selected parameter is then keyed into the keyboard and an ADJUST key struck to activate the adjustment process. Alternatively, the operator may strike a key corresponding to the crop to be harvested, a further key corresponding to the ambient moisture level of the crop, and then the ADJUST key. In this case the microprocessor reads from a stored table the values for adjusting all parameters so as to obtain a satisfactory sample and a maximum yield for the crop being harvested. The microprocessor sends signals to actuators for adjusting the various parameters and transducers sense the various parameters and provide information to the microprocessor for determining when the parameters have been adjusted to the selected values. A visual display is provided so that the operator may monitor the parameters and also observe entries keyed in at the keyboard.
