AI Technical Summary
Existing drilling rigs used for coalfield geological exploration often have residual soil on the drill bit after drilling, which affects their use and makes replacement and storage inconvenient.
A drilling rig comprising a frame, a drilling mechanism, and a cleaning mechanism has been designed. The frame is equipped with a swivel for mounting different drill bits. The cleaning mechanism uses a sliding plate and a guard plate in conjunction with a high-pressure nozzle to clean the drill bits. The sliding plate is driven by a hydraulic cylinder, and the guard plate is adjusted by a drive assembly to form a cylindrical structure, thereby enabling cleaning and convenient replacement of the drill bits.
This ensures that no soil residue remains after the drill bit is used, and facilitates drill bit replacement and storage, thereby improving drilling efficiency and the convenience of equipment maintenance.

[0002] A coalfield is a sedimentary basin or tectonic unit that was formed during geological history, contains relatively abundant coal resources, and has a certain scale. It is the basic geological unit where coal resources are located, and is usually composed of coal-bearing strata, coal seams, and related geological structures.
[0003] Coalfield exploration is the work of understanding the resource conditions of a mine, such as coal reserves, geological conditions of the mine area, coal seam occurrence conditions, hydrogeological conditions, coal type and quality.
[0004] In the process of geological exploration in coalfields, drilling rigs are usually required. When using existing drilling rigs for coalfield geological exploration, the drilling rig and drill bit are usually used to carry out geological exploration and sampling operations. However, due to the different actual conditions in different coalfields, various different drill bits are usually required.
