    • A cable burial system includes a cable burial tool having a base frame, a blade extending downwardly from the base frame and having a vertically oriented internal slot therein with a slot width, and a feed shoe with an arcuate feed shoe periphery and a feed shoe width less than the slot width of the blade. The feed shoe is pivotably connected to the base frame and is pivotable between a lowered position wherein the feed shoe lies within the slot, and a raised position wherein the feed shoe lies outside of the slot. The feed shoe includes a jet opening in a periphery of the feed shoe, and a source of pressurized water in an interior manifold of the feed shoe in communication with the jet opening in the periphery of the feed shoe. A guide is operable to guide a cable into the slot in contact with the feed shoe periphery when the feed shoe is in the lowered position. The guide includes a feed horn affixed to the base frame with an outlet end adjacent to the upper end of the slot and centered on the slot, and a pair of movable guide plates disposed adjacent to the upper end of the slot and centered on the slot. The guide plates are movable between a closed position centered with a first spacing sufficiently greater than the feed shoe width to permit the feed shoe to lie therebetween, and an open position having a second spacing greater than the first spacing. The cable burial tool is pivotably connected to a burial sled.
    • 电缆埋葬系统包括具有基架的电缆埋葬工具,从底座向下延伸并具有槽宽度的垂直取向的内槽的刀片,以及具有弓形进给蹄周边和进给蹄宽度的进给蹄 小于刀片的槽宽度。 馈送支架可枢转地连接到基座框架,并且可在下降位置之间枢转,其中馈送靴位于槽内,以及升高位置,其中馈送靴位于槽的外部。 进料靴包括在进料靴的周边中的喷射开口,以及供料靴的内部歧管中的加压水源,与进料靴的周边中的喷射开口连通。 当进给靴处于降低位置时,引导件可操作以将电缆引导到与供给靴周边接触的槽中。 引导件包括固定到基座的进给角,具有与槽的上端相邻的出口端并且位于槽的中心,以及一对可移动的引导板,其邻近槽的上端设置并且位于槽的中心 。 引导板可以在以足够大于进给靴宽度的第一间隔为中心的关闭位置之间移动,以允许进给爪位于其间,并且具有大于第一间隔的第二间距的打开位置。 电缆埋地工具可枢转地连接到埋地车尾。
