Abstract

Discloed is a hole digging machine anchored by means of driving of a lifting motor. The hole digging machine comprises an outer shell (8), the driving motor (9) and a hole digging drilling rod component (6) driven by the driving motor (9). The driving motor (9) is arranged in the outer shell (8) and is in power connection with a splined hole in a driving sleeve portion (61) of the hole digging drilling rod component (6) in an axial sliding mode through a fixedly-connected spline rod (91). The driving sleeve portion (61) of the hole digging drilling rod component (6) is fixedly connected with a drilling rod portion (62) of the hole digging drilling rod component (6) through a gradually-shrinking connecting portion (612). An axial extending spline is arranged on the peripheral face of the driving sleeve portion (61) and used for matching an axial extending spline groove in the inner peripheral wall of a barrel (71) of an outer thread sleeve component (7).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a hole digging machine driven and anchored by a lifting motor. 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. ...
