[0002] Geological exploration is to explore and detect geology through various means and methods, determine suitable bearing layers, and investigate and study the geological conditions of rock, stratum, structure, mineral resources, hydrology, and landform in a certain area. Geological exploration technology has developed from the early extensive mode relying on manual drilling and surface observation to a modern system integrating high-precision geophysical prospecting, remote sensing surveying and mapping, digital modeling, and intelligent algorithms. This evolution is characterized by multi-dimensional data integration, real-time dynamic monitoring, and artificial intelligence decision-making, aiming to break through the limitations of traditional methods in efficiency, accuracy, and adaptability to complex environments, and provide scientific support for resource development, engineering safety, and disaster prevention and control. The current technology frontier is further deepening and expanding in the direction of automated exploration equipment, multi-source heterogeneous data fusion analysis, and real-time deduction of geological processes;

[0003] The existing geological exploration drilling device with patent number CN118881300B includes a cleaning moving mechanism, which includes a load-bearing bottom plate.
