摘要： Under the control of a microprocessor first and second motors alternately drive first and second ends of a shear bar for adjusting the position of the shear bar relative to cutter head. The shear bar is adjusted so that it is substantially parallel to the cutter head even though the cutter head and shear bar may not be parallel at the time the adjustment is initiated. A knock sensor is provided for sensing impacts between the cutter head and shear bar, the knock sensor output signal being converted to a digital value for controlling the adjusting sequence. A knocker is provided for inducing vibrations in the shear bar to thereby test the operability of the knock sensor and its output circuitry. The sensitivity of the adjustment system to the output of the knock sensor is set automatically before an adjustment sequence begins to account for variations in the knock sensor, its output circuitry, and "noise" vibrations induced in the shear bar by normal machine operation.

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： An agricultural baler for forming and wrapping cylindrical packages of crop material. The baler includes a sledge assembly moveable between a starting position and full bale position. A plurality of rollers on the sledge assembly cooperate with an apron to define a bale forming chamber. Wrapping is accomplished via a system that includes a dispensing mechanism carried on the sledge assembly for dispensing sheet material, such as net or the like, into the bale forming chamber whereupon it is wrapped circumferentially around a formed cylindrical package of crop material as it is rotated in the chamber. The net wrapping system includes means for controlling the position of the dispensing mechanism relative to the sledge assembly by continuously sensing its position.

摘要： In a forage harvester having a motor driven sharpening stone driven back and forth along a path parallel to the axis of a rotating cutterhead to sharpen the knives of the cutterhead, and a door which normally prevents access to the knives, a control circuit is provided for controlling the opening of the door, the movement of the sharpening stone to sharpen the knives, and the closing of the door after the knives have been sharpened. The circuit is controlled by switches located at an operator's control panel and accessible to the operator while he is in the driver's seat of the harvester so that the operator does not have to leave his driving position to accomplish the knife sharpening operation. The circuit includes visual indicators located on the control panel for indicating the status of the circuit during the entire operation. The circuit includes a sensor circuit for sensing the rate of rotation of the cutterhead, the sensor circuit preventing knife sharpening from taking place unless the cutterhead is rotating at a rate greater than the rate required for proper sharpening of the knives.

摘要： A forage harvester having an automatic grinding mechanism for the knives of the cutterhead, the grinding mechanism comprising a carriage carrying grinding means and being reciprocated back and forth across the cutterhead in the griding mode by endless drive means. The carriage is coupled to the endless drive means by a coupling member which is attached to the endless drive means chain and pivotally attached to the carriage. The coupling member is shaped and dimensioned such that the pivot axis of the connection to the carriage is substantially coaxial with the axis of rotation of each of the two sprockets which define the extent of the two runs of the endless drive means when the connection of the coupling member to the chain passes around that sprocket in moving from one run of the chain to the other. The drive means is provided with control means having means for commanding the termination of the grinding mode, and carriage-position-sensing means operable to deenergize the drive means at the end of the grinding mode such as to dispose the carriage in substantially the same home position at the end of each grinding mode irrespective of the position of the carriage at the instant of commanding termination of the grinding mode.

摘要： An improved tine and tine connection device for removably connecting a tine to a pick-up reel tine bar in an agricultural harvesting machine. The improved tine incorporates an elastomeric portion interconnecting the tine fingers and the tine bar which enables limited tines movement relative to the tine bar. The elastomeric portion may also be shaped to fit around the tine bar enabling the elastomeric portion to also function as the tine mount. The tine mount is configured to enable installation by hand or using only simple tools and, once installed, provide sufficient connection strength to retain the tine in position during reel operation.
