易于调整挖坑深度的挖坑机
本技术涉及一种易于调整挖坑深度的挖坑机。
技术介绍
挖坑机以拖拉机、挖掘机或汽油机为动力源进行挖坑,让人从繁重的体力劳动解放出来。目前挖坑机广泛应用于植树造林、栽种果林等,其可快速挖坑,动力强劲,操作舒适,劳动强度低。以拖拉机、挖掘机为动力源的挖坑机,体型庞大,不适合在山地、丘陵、沟壑区植树造林或施肥,手提式的挖坑机体型较小、便于携带,便于在山地、丘陵、沟壑区植树造林或施肥,但手提式的挖坑机长时间使用时,需人力搬运,挖坑时需人使劲下压机器才能进行挖坑,长时间作业人的体力消耗太大,无法长时间操作,影响工作的效率。目前的手提式挖坑机挖坑深度基本固定,当遇到栽种不同的苗木时,一般需要更换钻头,更换钻头费时费力,降低工作效率。
