Rock coring machine

Abstract

The invention discloses a rock coring machine, which comprises a base, a holder, a lifting bracket, a drilling assembly, a first power unit, and a second power unit; the holder is arranged on the base, and is used for holding a rock to be cored; relative to the base, the lifting bracket is liftably supported on the base; the drilling assembly is rotatably arranged on the lifting bracket, and is used for coring the rock; the first power unit and the second power unit are respectively fixed on the lifting bracket, and the first power unit and the second power unit can be switched to be transmissively connected to the drilling assembly, so that one of the power units is chosen to supply driving force to the drilling assembly. Because the rock coring machine has a manual power mode and an electric power mode, in the absence of power supply, the rock coring machine can ensure that the work of rock coring can be carried out. Moreover, the rock coring machine is small, disassemblable and convenient to move for operation, and in particular, the rock coring machine is applicable to the work of field rock coring. Because of the characteristics of the invention, the rock coring machine can be widely applied in geological exploration works, such as early-stage exploration of oil and gas fields, regional geological mapping, geophysical and geochemical sampling, palaeomagnetic sampling and geological disaster prevention.

Description

technical field [0001] The invention relates to the technical field of geological survey equipment, in particular to a rock coring machine. Background technique [0002] In the field of geological survey, geologists need to collect information in rocks when analyzing strata, and at this time they will encounter rock coring work. A rock coring machine is required for rock coring work. [0003] At present, most of the rock coring machines used by researchers are relatively large and heavy machines, and most of them use electricity or fuel oil. If geological workers want to carry out coring work in the field, this coring machine is not easy to carry, and in the absence of electricity and fuel, the coring machine cannot work, which will undoubtedly bring great difficulties to the workers. At present, the coring bits carried by the coring machine are generally relatively large, and the cores taken out are naturally relatively large. Sometimes such large-diameter cores cannot me...

Problems solved by technology

If geologists want to carry out coring work in the field, this kind of coring machine is not easy to carry, and in the absence of electricity and fuel, the coring machine cannot work, which will undoubtedly bring great difficulties to the workers

At present, the coring bits carried by the coring machine are generally relatively large, and the cores taken out are naturally relatively large. Sometimes such large-diameter cores cannot meet the requirements of project research. For example, core CT analysis requires small and thin cores. The smaller the diameter, the more precise the analysis results
