日本一家公司研制成一种液压式树木移植机,不仅减轻了工人的劳动强度,也大大加快了移植速度。这种树木移植机安装在推土机的前部。一台钢制3立方米的挖斗安在推土机正前方,与液压铲一样的装有力臂的1.5立方米挖斗各安在推土机前方的左右。这3台挖斗交互插到树木的根下,切断一些树根再掘入,一举抱住带土的树根掘起。这样拔起的树 A Japanese company developed a hydraulic tree transplanter, not only reduce the labor intensity of workers, but also greatly speed up the transplant speed. This tree transplanter is installed on the front of the bulldozer. A 3-cubic-meter bucket of steel is placed directly in front of the bulldozer, with 1.5-cubic-meters bucket shrouds of the same strength as the hydraulic shovels, each resting on the front of the bulldozer. The three bucket interactively inserted under the roots of the trees, cut off some of the roots and then dug in one fell swoop embracing the roots of soil digging up. This uprooted tree
