    • The disclosure relates to a sugar cane harvester having a pair of contra-rotating cutters to cut cane at its base and to lift the cane cut-ends first onto a conveyor which delivers the cane through de-trashing devices and then to a pair of rollers which draw the cane from the conveyor and propel it into the open end of a container against an adjustable barrier disposed along the container from said open end. The barrier is positioned to suit the length of the cane being harvested and cutters are provided to cut the cane tops from the stalks where they protrude at the open end of the conveyor to separate the tops from the stalks.
    • 本公开涉及一种甘蔗收割机,其具有一对反向旋转刀具,以在其底部处切割甘蔗并且将拐杖切割端首先提升到输送机上,该输送机通过脱砂装置输送甘蔗,然后到达一对辊 其从输送机牵引甘蔗并将其推进到容器的开口端中,抵靠来自所述开口端的容器设置的可调节屏障。 隔离物定位成适合正在收获的手杖的长度,并且提供切割器以从茎秆上切割拐杖顶部,其中它们在输送机的开口端处突出以将顶部与茎分离。

    • A portable tool (41) for determining diameters and lengths along fallen trees (stems). The tool (41) includes callipers (2,3) for measuring diameters at positions along the stem and a tape measure (5) for measuring distance along the stem. In use, spinning lasers (57) are used to set up datum planes (51) either vertically beside the stem or horizontally above the stem. The tool (41) is also provided with a laser sensor (13) so that distance may be determined from the stem to the datum (51) to enable the curvature of the log to be determined. Each of the measuring devices on the tool (41) provide a visual display of their measurements and encoders (9,26) provide an electronic signal representative of the measurements to a computer (19) on the tool (41). Software running on the computer (19) uses these measurements to "paint" a picture of the stem and, using data relating to the value and current desirability of various lengths and qualities of logs, determines the optimum cutting positions along the stem to maximize the value of the logs from the stem.
    • 一种用于确定沿着树木(茎)的直径和长度的便携式工具(41)。 工具(41)包括用于测量沿着杆的位置处的直径的卡钳(2,3)和用于测量沿着杆的距离的卷尺(5)。 在使用中,旋转激光器(57)用于在杆上垂直地设置或者竖直地在杆上方设置基准平面(51)。 工具(41)还设置有激光传感器(13),使得可以从杆到基准(51)确定距离,以使得能够确定原木的曲率。 工具(41)上的每个测量装置提供它们的测量和编码器(9,26)的视觉显示,以将表示测量的电子信号提供给工具(41)上的计算机(19)。 在计算机上运行的软件(19)使用这些测量来“绘制”茎的图片,并且使用与日志的各种长度和质量的价值和当前期望值有关的数据来确定沿茎的最佳切割位置以最大化 来自茎的日志的值。
