摘要： One or more techniques and/or systems are disclosed for automatically adjusting conditioning rollers of a windrower implement, such as those used to condition hay and other windrowed crops. Adjustments can be made on the fly to rollers used to condition the crop based on several factors such as the condition of the crop, the density, speed, header conditions, and more. Sensors can be used to detect the crop's and others' conditions, and automatic adjustments can be made, such as the distance between conditioning rollers, and/or the pressure applied by the rollers, to meet a desired crop condition for the windrows.

摘要： A conditioning roller assembly includes two conditioning rollers which are rotatably mounted on associated bearing arrangements, and a holder which includes a first holder component and a second holder component that are connected together by a hinge and a spring arrangement for providing a pre-tensioning of the conditioning rollers. The first holder component is releasably connected to the first bearing arrangement, the second holder component is releasably connected to the second bearing arrangement, and the conditioning rollers, with the bearing arrangements, are detachable in each case from the components without the holder being disassembled.

摘要： A conditioner assembly in an agricultural implement for conditioning cut crop material includes a top roll and a bottom roll rotatably supported by a pair of lateral side walls. The top roll is arranged relative to the bottom roll to define a roll gap therebetween for conditioning the cut crop material as the cut crop material passes therethrough. A stabilizing link extends between each of the lateral side walls and the top roll for pivotally coupling the top roll to the conditioner frame, and an adjustment mechanism extends between each of the lateral side walls and the top roll. The adjustment mechanism is selectively and remotely actuatable to automatically pivot the top roll toward and away from the bottom roll, thereby decreasing and increasing the roll gap for optimally conditioning different types and volumes of cut crop material received by the agricultural implement.

摘要： A crop conditioning device for an agricultural harvesting machine. The crop conditioning device includes a frame, a first conditioning roll, and a second conditioning roll. The crop conditioning device also includes a tension member operably connected to the second conditioning roll. The tension member is configured for applying a tension force on the second conditioning roll. The crop conditioning device also includes a tension actuator operably connected to the tension member. The tension actuator is configured for adjusting the tension force applied by the tension member. The crop conditioning device also includes a pair of control rods respectively connected to the pair of lateral ends of the second conditioning roll. The crop conditioning device also includes a pair of roll-gap actuators respectively and operably connected to the pair of control rods. The pair of roll-gap actuators are configured for pivoting the second conditioning roll to adjust the roll gap.

摘要： A forming shield arrangement configured for a windrowing work vehicle is supported for movement by a support structure. The forming shield arrangement is configured to at least partly shape a windrow of a crop material. A method of operating the forming shield arrangement includes receiving, by a processor of a control system from a memory element, a stored position setting that corresponds to a position of the forming shield arrangement relative to the support structure. The method also includes processing, by the processor, a positioning control signal based, at least in part, on the stored position setting. Moreover, the method includes changing, with an actuator, the position of the forming shield arrangement according to the positioning control signal.

摘要： A system and computer-implemented method for sensing an amount of free water in cut crop material and automatically adjusting an operating parameter of a mower conditioner to optimize the amount of free water. A sensor located at the exit of a conditioning mechanism measures an actual free water content value of the material as it exits the conditioning mechanism, a processor compares the actual value to maximum and minimum values, and if the actual value is outside this range, automatically adjusts an operating parameter, such as a gap between pairs of conditioning rollers, a pressure exerted by the rollers, or a speed of the mower conditioner, to optimize the actual value. Another sensor may be located at the entrance of the conditioning mechanism. The processor may take into account an operator-selectable value weighting the actual free water content versus a dry down time when adjusting the operating parameter.

摘要： A conditioner unit (6) for conditioning an agricultural crop material comprises a pair of rolls (20a, 20b) configured for rotation in opposite directions and providing a nip (22) through which crop material passes. An adjusting mechanism (31) is provided for adjusting a pressing force applied by the rolls (20a, 20b) to the crop material as it passes through the nip. The adjusting mechanism (31) includes at least one hydraulic actuator (30) connected to at least one of the rolls (20a, 20b) and a hydraulic circuit (33) that supplies hydraulic fluid to the actuator (30), the hydraulic circuit being configured so that in a first operational mode the rolls (20a, 20b) are pressed towards one another and in a second operational mode the rolls (20a, 20b) are pushed apart to provide a gap between the rolls.

摘要： An impeller conditioner for an agricultural mowing machine includes a rotor, an attachment device located on the rotor, a tine device pivotally attached to the rotor between a first end and a second end of the tine device via the attachment device, and a positioning device located on one of the rotor and the attachment device. The positioning device include a tapered portion which restricts the tine device in a first position to have less lateral movement than the tine device in a second position. The first position can be an operational position and the second position can be a non-operational position.

摘要： A tubular for processing crops can include a body having an outer surface and protrusions extending outwardly from the outer surface. The protrusions can be arranged in bands that are spaced apart along the outer surface to define gaps therebetween that form grooves extending around a circumference of the body. Each band of protrusions can be positioned offset with respect to at least one adjacent band of protrusions such that the protrusions form a spiraling configuration around a longitudinal axis of the body.
