Abstract

The invention discloses a hole digging machine with an adjustable hole digging speed. The hole digging machine 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), an electronic control device (14) is arranged on a shell of the driving motor (9), is electrically connected with the driving motor (9) and is used for controlling and regulating the rotational speed of the driving motor (9), the driving motor (9) 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), and 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).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a hole digging machine with adjustable hole digging speed. 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. More...
