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： A telescopic rollover protective structure for use with an orchard tractor is disclosed wherein the protective member is operatively engaged with a counterbalancing spring to offset the weight thereof and to facilitate the movement of the protective structure between raised and lowered positions. A locking mechanism is connected to the mounting frame and engageable with the movable protective member to restrict movement thereof when the locking mechanism is engaged therewith. The counterbalancing system includes a compression spring concentrically mounted on a telescopic rod housed within the hollow protective member legs.

摘要： An implement, such as a cutterbar on an agricultural harvesting machine, is automatically position-controlled to maintain a reference position relative to the ground surface. The implement is mounted so that it may be raised, lowered or tilted and the control is such that tilting movements are preceded by, or are carried out concurrently with, a raising or lowering movement when one end of the implement is at the reference position and the other end is between the reference position and the ground surface. Manually operated UP and DOWN switches not only control up and down movements of the implement but also inhibit and restore automatic control of implement positioning. A set/reset switch enables manual selection of a predetermined reference position or the selection of the present implement position as the reference position.

摘要： An agricultural harvesting machine having a cutting element movably supported thereon is provided with a height sensor including a transmitter and a receiver mounted for movement with the cutting element. The transmitter directs bursts of sound waves in the range of about 5 KHz toward the ground and echoes of the bursts are picked up by the receiver, the elapsed time between transmission and reception being an indication of the height of the cutting element above the ground. To distinguish between echoes of the bursts and environmental noise picked up by the receiver, the bursts are encoded by transmitting them in pairs, the bursts of a pair being of fixed duration and separated by a fixed interval of time. The duration of each signal and the time spacing between signals is checked and if they are not of the correct duration or are not separated by the fixed interval of time they are rejected as noise. The time between transmission and reception of a burst is measured to provide an indication of the height of the cutting element. The measured height is compared with a reference or desired height and the difference value is used to control movement of the cutting element to the desired height.

摘要： In a leaf loading method, leaves are picked up from the ground by operating a rotary beater and a rotary broom. The leaves are then delivered between the beater and the broom by rotating the beater and the broom in opposite directions. Next, the leaves are guided from between the beater and the broom toward an auger disposed rearwardly of the broom. Finally, the leaves are transferred from the auger into a thrower by rotating the auger and then the leaves are discharged by operating the thrower.

摘要： A bale forming method for use with round balers is disclosed. Typically round balers are operated in a manner whereby crop material is fed into only one side of the bale forming chamber at a time. The disclosed method includes positioning a round baler so that crop material is fed into the right side of the bale forming chamber, generating a signal in a first indicator light in response to a predetermined expansion of the bale forming chamber, repositioning the round baler so that crop material is fed into the left side of the bale forming chamber, and generating a signal in a second indicator light in response to a further predetermined expansion of the bale forming chamber.

摘要： A bale shape monitoring system for round balers includes first and second indicator lights, and bale shape monitor apparatus for alternately generating signals in the indicator lights in response to predetermined expansion of the baling chamber of round balers. Typically round balers are operated in a manner whereby crop material is fed into only one side of the baling chamber at a time. The signals generated in the indicator lights are used by the operator of a round baler as an indication of when to weave the baler to feed crop material into the other side of the baling chamber. Proper use of the disclosed system prevents the formation of poorly shaped bales while reducing operator fatigue.

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.
