Abstract

The invention discloses a handheld excavating device, and relates to the technical field of construction equipment. The handheld excavating device aims to improve the construction speed of a manual hole digging pile, reduce the labor intensity of workers, and improve construction safety. An electromotor drives a drill rod to rotate through a reducer to carry out digging and breaking on a soil layer, and broken soil is lifted along a cylinder under the action of compressed air, and is discharged through the outlet of the side face of the cylinder. The handheld excavating device is suitable for the construction of the manual hole digging pile.

Description

technical field [0001] The invention relates to a construction machine tool, in particular to a hand-held excavator for manual hole-digging pile construction. Background technique [0002] A large number of artificial hole-digging piles are used in the foundation piles of many large-scale projects such as housing construction, bridge engineering, and power transmission and transformation projects (electric towers). Use shovel and other tools to excavate, and when encountering hard soil layers, use hammers and drills to break them. The spoils are loaded in buckets, and vertically lifted out of the wellhead by human gallows or small winches. Manual excavation is not only slow and inefficient, but also has high labor intensity and poor safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art, and provide a hand-held excavator, which can increase the construction speed of...
