    摘要： In a forage harvester, a shear bar is adjusted relative to the knives of a rotating cutterhead by selectively energizing first and second motors to move one or the other end of the shear bar toward the cutterhead. A vibration sensor senses vibration of the shear bar and controls a circuit to deenergize an energized motor when vibration is induced in the shear bar. The vibration may be caused by impact of the cutterhead knives on the shear bar (a true hit) or by random noise (detected as a false hit). To discriminate between false hits and true hits, an energized motor is stopped when a first hit (true or false) is detected. A timer is set to time an interval at least as great as the time it takes the cutterhead to make one revolution, and during this interval the vibration sensor is repeatedly sampled to determine if a second hit has occurred. If a second hit is detected during the interval the first hit is assumed to be a true hit. If a second hit is not detected during the interval then the first hit is assumed to be a false hit and the deenergized motor is restarted.

    摘要翻译： 在饲料收割机中，通过选择性地激励第一和第二电动机使剪切杆的一端或另一端朝向刀头移动，相对于旋转刀架的刀来调整剪切杆。 振动传感器感测剪切杆的振动，并且当在剪切杆中产生振动时，控制电路对通电电动机通电。 振动可能是由于刀刀在剪切杆上的冲击（真正的撞击）或随机噪声（被检测为假命中）引起的。 为了区分虚拟命中和真实命中，当检测到第一次命中（真或假）时，通电电机停止。 定时器被设置为至少与刀头进行一圈的时间相同的时间间隔，并且在该间隔期间，重复采样振动传感器以确定是否发生了第二次命中。 如果在间隔期间检测到第二次命中，则第一次命中被假定为真实命中。 如果在间隔期间未检测到第二次命中，则第一次命中被假设为假命中，并且重新启动断电马达。

    摘要： A forage or picking harvester unit includes a cylindrical cutter followed by an impeller fan with a crushing device in the path between the cutter and the fan. In the cylindrical cutter, the cutting wheel shaft is arranged perpendicularly relative to the shaft of the impeller fan. The crushing device is formed of crushing rollers with the roller axes extending parallel to the cutting wheel shaft. The crushing rollers are positioned in the path of the material flowing from the cylindrical cutter into the impeller fan. The circumferential surfaces of the crushing rollers are fluted in the direction parallel to the roller axes. The fluted surfaces form alternating teeth and recesses so that the circumferential surfaces of the crushing rollers can intermesh.

    摘要： In a forage cutter, a cutting wheel is rotatably mounted within a housing. For an angular portion of the wheel relative to the housing, its outer circumferential periphery is positioned adjacent to a backing wall of the housing. Alternating knives and blades are attached to the cutting wheel about its circumferential periphery with the knives coacting with a stationary cutting plate to cut forage material introduced into the housing. After the material is cut it is carried downwardly to a space where it is crushed and the crushed material is moved upwardly by the blades on the cutting wheel to an outlet passageway. The crushing space is provided by diverging the backing wall outwardly from the outer circumferential periphery of the cutting wheel. Following the crushing space, the backing wall converges inwardly toward the outer circumferential periphery of the cutting wheel. The outlet passageway follows the inwardly converging backing wall in the direction of rotation of the cutting wheel. The crushing action is afforded by cooperating crushing rollers or by a crushing roller cooperating with a friction surface.

    摘要： In a forage harvester having a rotatable cutterhead and adjacently-positioned shearbar, an upper rear feed roll is mounted above and forwardly of the shearbar for pivotal movement relative to an upper front feed roll by a pair of arms which interconnect the rolls. A tensioning assembly is coupled to each of the arms. An actuatable latching mechanism is connecting to the tensioning assembly and movable to a first position for placing the tensioning assembly in a first condition in which the rear feed roll is biased toward a lower operative position adjacent the cutterhead and shearbar. The latching mechanism is also movable to a second position for placing the tensioning assembly in a second condition in which the bias on the rear feed roll is relaxed, whereby the rear feed roll may now be pivotally moved relative to the front feed roll to an upper inoperative position generally above the front feed roll and remote from the cutterhead and shearbar to thereby expose and render the shearbar readily accessible for servicing.
