    • A mechanism (25, 40) for changing the cutting angle of the cutterbar (20) on a crop harvesting machine (10), such as a mower-conditioner orwindrower, relative to the ground (G) is disclosed wherein the cutting angle can be changed while the harvesting machine (10) is being operated. This on-the-go adjustment mechanism includes a hydraulic cylinder (40) positioned as the top link between the frame (12) of the harvesting machine and the header (15) in which the cutterbar (20) is mounted. Changes in the length of the hydraulic cylinder (40) effect a pivotal movement of the header (15) aboutthe lower links (27) interconnecting the frame (12) and the header (15) to change the angle of the cutterbar (20) relative to the ground (G). By connecting the cutting angle adjustment cylinder (40) to the hydraulic circuitforthe header lift cylinders (32) and by sizing the bore of the angling cylinder (40) such that its stroke is activated prior to activation of the lift cylinders (32), the cutterbar cutting angle can be varied from the operator's seat through manipulation of the hydraulic control lever for the header lift system while the machine is in motion cutting crop. An adjustment bracket (50) is provided with variousstop settings to control the range of the adjustment of the cutting angle obtainable through manipulation of the angling cylinder (40).

    • A harvester (10) which uses a rotary style cutter bed (30) has a series of rotary cutters (32a-32j) extending across the path of travel of the machine and rotatable about individual upright axis. Part of the cutter bed (30) is a flat gear case (34) containing a train of intermeshed spur gears (35) that serve to distribute power between the cutters above the gear train. Each end of the gear case (34) has a hollow, gearless extension welded thereto which supports at least one additional outboard cutter that receives its driving power exteriorally of the gear case (34). One embodiment uses a mechanical drive to bring power to the upright shaft of the cutter having the first spur gear so that the cutters with gears receive all their power from the driven cutter. The outboard cutters not having gears are driven by exterior, over-the-top drive mechanism coupled with the shafts of the first and last geared cutters, such drive mechanism alternatively taking the form of timing belts (120).
    • 使用旋转式切割床(30)的收割机(10)具有跨越机器的行进路径延伸的一系列旋转切割器(32a-32j),并可围绕单独的竖直轴线旋转。 切割床(30)的一部分是平坦齿轮箱(34),其包含一系列相互啮合的正齿轮(35),用于在齿轮系上方的切割器之间分配动力。 齿轮箱(34)的每个端部具有焊接到其上的中空的无齿轮延伸部,其支撑至少一个附加的外侧切割器,其接收其在齿轮箱(34)的外部的驱动力。 一个实施例使用机械驱动器向具有第一正齿轮的切割器的立式轴驱动力,使得具有齿轮的切割器从驱动的切割器接收所有的动力。 不具有齿轮的外侧切割器由外部驱动,顶部驱动机构与第一和最后一个齿轮刀具的轴联接,该驱动机构交替地采取同步皮带(120)的形式。

    • A crop harvester (10) of the rotary cutter bed type has a series of rotary cutters (32a-32j) extending across the path of travel of the machine and rotatable about individual upright axes. The cutter bed (30) extends in opposite directions beyond the ends of a central discharge opening (102) to the conditioner rolls. Cutters (32a; 32b; 32i; 32j) located outboard of the opening direct cut crop materials along the front of the cutter bed (30) until the opposite extremities of the discharge openings are reached, whereupon pairs of cooperating, oppositely rotating cutters in front of the opening function to propel the crop material rearwardly with the main flow of cut materials. Alternative forms of conveying means (292; 296; 306) are provided in association with the outboard cutters (32a; 32b; 32i; 32j) for moving the cut crop centrally without the use of augers or other additional gathering mechanism behind the row of cutters.

    • A crop harvester (10) is provided with a rotary type cutter bed (30) in which a series of rotary cutters (32a-32j) extend across the path of travel of the machine for rotation about individual upright axes. A hydraulic drive for the cutter bed includes a variable volume pump (210) driven by the output shaft of an engine (208) associated with the harvester. The operating circuit of the hydraulic drive pumps oil through the circuit at a certain rate of flow, depending upon the engine speed and the position of a swash plate (260) within the pump. A control circuit communicating with the operating circuit (228) is capable of sensing load in the operating circuit tending to lug down and reduce the speed of the engine (208), which would normally reduce the flow rate and hence the cutter speed. However, in response to detecting such increased load, the control circuit compensates by adjusting the position of the swash plate (260) so as to correspondingly pump more oil at the lower engine speed, thus maintaining the cutter speed essentially constant.
    • 作物收割机(10)设置有旋转式切割床(30),其中一系列旋转切割器(32a-32j)跨过机器的行进路径延伸以围绕各个直立轴线旋转。 用于切割床的液压驱动器包括由与收割机相关联的发动机(208)的输出轴驱动的可变容积泵(210)。 液压驱动器的操作电路根据发动机转速以及泵内的斜盘(260)的位置,以一定的流速通过电路泵送油。 与操作电路(228)通信的控制电路能够感测到操作电路中的负载倾向于下降并降低发动机(208)的速度,这通常会降低流量并因此降低切割器速度。 然而,响应于检测到这种增加的负载,控制电路通过调节斜盘(260)的位置来补偿,以相应地在较低的发动机转速下泵送更多的油,从而保持刀具速度基本恒定。
