Engineering geological exploration sample sampling device

Abstract

The invention provides an engineering geological exploration sample sampling device which comprises a driving frame, a sleeving hole is formed in the driving frame, a driving rod is rotationally connected in the sleeving hole, a driving motor is arranged on the driving frame, the driving rod is fixedly connected to the output end of the driving motor, a limiting frame is arranged on the driving frame, and two mounting plates are symmetrically arranged on the limiting frame; two limiting assemblies are symmetrically arranged on the limiting frame, each mounting plate is connected with the limiting frame through the corresponding limiting assembly, a sample barrel is connected between the two mounting plates, a first sample storage groove, a second sample storage groove, a third sample storage groove and a fourth sample storage groove are formed in the sample barrel, a sampling barrel is arranged at the bottom of the sample barrel, and the sampling barrel is communicated with the sample barrel. A drill bit is buckled on the driving rod, spiral teeth are arranged on the circumferential outer wall of the drill bit, and the drill bit is arranged in the sampling barrel and the sample cylinder. According to the invention, a plurality of equivalent to-be-detected samples can be directly formed during geological exploration sampling, manual sample separation after geological exploration sampling is not needed, and later operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of geological exploration sampling devices, in particular to a sample sampling device for engineering geological exploration. Background technique [0002] The major of hydraulic environment is the major of hydrology and engineering geology. Hydrogeology began to develop from the search and utilization of groundwater sources, and gradually carried out theoretical research around practical applications. Engineering geology is the investigation, research, solution and human activities and various projects. The science of construction-related geological problems. The major of hydraulic environment can work in engineering geological survey and design, water conservancy and hydropower survey and design, urban and rural construction planning, road traffic survey and design, mining enterprises, environmental monitoring and land and resources management. [0003] In the hydraulic environment, it includes environmen...

Problems solved by technology

[0006] The purpose of the present invention is to provide a sample sampling device for engineering geological survey, to solve the problem of the existing geological survey sampling device proposed in the above background technology, after the geological crushing is carried out by means of a crushing structure, the broken items are manually selected and stored, and When sampling after geological survey, it is necessary to manually separate the brought back samples to be inspected, and then form multiple equal samples to be inspected. The whole process is cumbersome and inconvenient for later operations.
