Abstract

The invention discloses a hole digging machine which comprises an external shell (8), a driving motor (9) and a hole digging drill rod assembly (6). The hole digging drill rod assembly (6) can be driven by the driving motor (9), the driving motor (9) is arranged in the external shell (8) and is axially slidably in power connection with a spline hole in a driving sleeve (61) of the hole digging drill rod assembly (6) by a fixedly connected spline rod (91), the driving sleeve (61) of the hole digging drill rod assembly (6) is fixedly connected with a drill rod (62) of the hole digging drill rod assembly (6) by a gradually reducing connecting portion (612), and axial extending keys are arranged on the outer peripheral surface of the driving sleeve (61) and are used for being matched with axial extending key slots in the inner peripheral wall of a sleeve (71) of an externally threaded sleeve assembly (7).

Description

technical field [0001] The application relates to the field of construction machinery, specifically a hole digging machine. Background technique [0002] In some construction sites, such as garden construction, road construction and building construction, some hole digging operations are often required, and a hole digger is needed in this case. [0003] Hole digging operations are often carried out on soil floors. Some existing hole digging machines need to be manually controlled in the case of small-scale construction, and in the case of large-scale construction, they need to be controlled by a mechanical arm to provide the mechanical force for pressing down and make the pressing down follow the depth of the hole. And keep the pressure on. [0004] This way tends to increase equipment cost and use cost. [0005] And some machinery in other fields will not be suitable for the digging operation of above-mentioned situation well. Moreover, the equipment used for its operat...
