Abstract

The invention provides a hole digging machine realizing anchoring through being driven by an air pressure cylinder. The hole digging machine comprises an outside casing (8), a driving motor (9) and a hole digging drill pipe component (6), wherein the hole digging drill pipe component (6) is driven by the driving motor (9); the driving motor (9) is arranged inside the outside casing (8) and is in axially gliding power connection with a spline hole formed in a driving sleeve part (61) of the hole digging drill pipe component (6) through a fixedly connected spline rod (91); the driving sleeve part (61) of the hole digging drill pipe component (6) is fixedly connected with a drill pipe part (62) of the hole digging drill pipe component (6) through a gradually reduction connecting part (612); and an axial extending key is arranged on the outer peripheral surface of the driving sleeve part (61) and is used for being matched with an axial extending key slot formed in the inner peripheral wall of a tube body (71) of an external threaded 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 pneumatic cylinder. 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 we...
