Rock core splitting sampler for geological mineral drilling

Abstract

The invention discloses a rock core splitting sampler for geological mineral drilling. The rock core splitting sampler comprises a discharging shell and a base, wherein the discharging shell is connected with the base through an opening and closing assembly, the discharging shell is in a hollow cylindrical shape, the bottom end of the discharging shell is provided with a waste groove, the axis direction of the waste groove is consistent with the axis direction of the discharging shell, the waste groove is communicated with the interior of the discharging shell, a pushing assembly is arranged at one axial end of the discharging shell, a long cutting hole longitudinally penetrating through the end wall of the top end of the discharging shell is formed in the top end of the discharging shell, a cutting sheet is arranged in the long cutting hole, the center position of the cutting sheet is axially connected with the output shaft of a cutting motor, and the cutting motor is connected with the base through an adjusting assembly. According to the invention, the whole splitting operation is completed in the discharging shell, so that dust generated in the splitting process is prevented from falling into the atmosphere to pollute the environment, and stone chippings are prevented from splashing out to injure operators.

Description

technical field [0001] The invention relates to the field of geological drilling, in particular to a core splitting sampler for geological and mineral drilling. Background technique [0002] In geology, the cylindrical rock samples drilled with ring bits and other coring tools are called cores. Cores are important physical geological data for studying and understanding underground geology and mineral conditions. In geological and mineral exploration, when the core is used for analysis and research, it is usually necessary to split the core, half of which is used for sampling and testing to understand and analyze the geological conditions, and the other half is sealed for sample preservation. [0003] When splitting and sampling the rock core, a large amount of dust and splashed stone debris will be generated. While polluting the environment, the splashed stone debris will easily cause damage to the cutting personnel and pose a threat to the life safety of the cutting person...
