Abstract

A hole digging machine with an alarming device comprises an outside shell (8), a driving motor (9) and a hole-drilling drill rod part (6) driven by the driving motor (9). The driving motor (9) is arranged in the outside shell (8) and is in power connection with a spline hole in a driving sleeve portion (61) of the hole-digging drill rod part (6) through a spline rod (91) in fixed connection in an axially slidable manner, the driving sleeve portion (61) of the hole-digging drill rod part 96) is fixedly connected with a drill rod portion (62) of the hole-digging drill rod part (6) through a gradually-contracting connection portion (612), and an axial extending key is arranged on the outer peripheral face of the driving sleeve portion (61) and used for being matched with an axial extending key groove in an inner peripheral wall of a barrel (71) of an outer thread sleeve part (7).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a hole digging machine with an alarm device. 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 equi...
