Hole digging machine with rainproof and dustproof functions

Abstract

The invention relates to a hole digging machine with rainproof and dustproof functions. The hole digging machine comprises an outer casing (8), a driving motor (9) and a hole digging drill rod component (6), wherein the hole digging drill rod component (6) is driven by the driving motor (9); the top of the outer casing (8) is provided with a protective cover (18); a fixing rod (17) is arranged inside the protective cover (18) and is fixedly connected with the top of the outer casing (8); the protective cover (18) is integrally in a herringbone shape, and is used for preventing the outer casing (8) from oxidative corrosion due to getting wet by rainwater, and the rainproof and dustproof effects are achieved; the driving motor (9) is arranged in the outer casing (8), and is in axial and slidable power connection with a spline hole formed in a driving sleeve part (61) of the hole digging drill rod component (6) through a fixedly connected spline rod (91); and the driving sleeve part (61) of the hole digging drill rod component (6) is fixedly connected with a drill rod part (62) of the hole digging drill rod component (6) through a gradually reducing connecting part (612).

Description

technical field [0001] The application relates to the field of construction machinery, in particular to a rain-proof and dust-proof 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...

[0004] This method tends to increase equipment cost and use cost

[0005] And some machinery in other fields will not be well suited for the digging operation in the above situation

Moreover, the flexibility of the equipment used for its operation is poor, and it is difficult to adapt to different construction conditions and requirements.
