Drilling machine

Abstract

The invention provides a drilling machine. A gear bank is meshed with gear teeth on a power outputting shaft of a motor; a secondary drill bit fixing rack is fixedly arranged on a shell rack; a secondary drill bit gear on a secondary drill bit is meshed with a gear on a main drill bit; the gear bank is fixed on the shell rack through a gear bank fixing rack; a steel wire lifting rope is arranged on a ground rack; the ground rack is connected with the shell rack through the steel wire lifting rope; and the shell rack is provided with a pure water sprayer and a mud pumping opening. The drilling machine has the advantages that the drilling machine can be used for drilling holes instead of manual operation, occupational injury can be avoided, the drilling machine is high in drilling efficiency, simple in structure and convenient to implement, investment on labor and materials can be reduced, and the construction time is saved. When the drilling machine runs, the pure water sprayer can spray water to wet ash generated in a drilling process so that the ash is stirred into mud, and the mud can be pumped away from the mud pumping opening.

Description

technical field [0001] The invention belongs to the field of drilling, and in particular relates to a drilling machine. Background technique [0002] In the prior art, when some places need to use holes for construction, they are usually drilled manually. Such a punching method is single, with low efficiency and poor effect. When large-scale production is required, due The operating physical strength of personnel is limited, and work-related injuries are prone to occur. Now there are punching machines, but the cost of fastener punching machines is too high and the structure is too complicated. For the current installation and renovation of water pipes for small towns and rural residents, roadways need to be excavated. Ditching in the courtyard is done, which is labor-intensive and time-consuming, and also affects the traffic of residents, and the construction efficiency is still very low. Contents of the invention [0003] Aiming at the above-mentioned prior art, ...
