Swamp land fixed-point sampling device for geological survey

Abstract

The invention provides a swamp land fixed-point sampling device for geological survey, and relates to the field of geological exploration. The swamp land fixed-point sampling device for geological survey comprises a sampling disc, the upper end of the sampling disc is fixedly connected with a limiting pipe, an inner groove of the limiting pipe is fixedly connected with a positioning rod, the outer surface of the positioning rod is sleeved with a dense pressing ball, the upper portion of the limiting pipe is fixedly connected with a pressure pumping cylinder, the outer surface of the pressure pumping cylinder is sleeved with a shell supporting cylinder, and the two sides of the shell supporting cylinder are slidably connected with extrusion buckles. The sides, close to each other, of the extrusion buckles are in contact connection with a shrinkage mechanism, and the shrinkage mechanism is fixedly connected with the shell supporting cylinder and located between the pressure pumping cylinder and the shell supporting cylinder. According to the swamp land fixed-point sampling device for geological survey, collected mud is thrown into a bearing body through rotation of the mud throwing disc, samples enter a specific place to be stored, the bearing body can change the storage space through the mass of the samples in the bearing body, the effect of quantitative storage change during sampling is achieved, and the effect of separated storage of multiple times of sampling is achieved.

Description

technical field [0001] The invention relates to the field of geological survey, in particular to a swamp fixed-point sampling device for geological survey. Background technique [0002] Geological survey is based on natural science and earth science, with geological survey, general survey and exploration of mineral resources, geological structure and geological background of major projects as the main object, and geological, geophysical and geochemical technology , mathematical geological methods, remote sensing technology, testing technology, computer technology, etc. as a leading engineering field serving the national economic construction. [0003] In the process of geological survey, it is necessary to sample various topographical surveys. However, sampling in swamps is more difficult. Since the samples are all mud and cannot be stacked, and fixed-point sampling needs to travel to and from the swamp to increase the workload and risk factor, so a fixed-point sampling meth...
