Description

Technical Field

[0001] The utility model relates to the technical field of geophysical exploration, in particular to a sampling device for analyzing the density of rocks in geophysical exploration. Background Technique

[0002] Geophysical exploration, abbreviated as geophysical prospecting, refers to detecting formation lithology, geological structures and other geological conditions by studying and observing the changes of various geophysical fields. Since different rock strata media that make up the earth's crust often have differences in density, elasticity, conductivity, magnetism, radioactivity, and thermal conductivity, these differences will cause local changes in the corresponding geophysical fields. By measuring the distribution and change characteristics of these physical fields and analyzing and studying in combination with known geological data, the purpose of inferring geological properties can be achieved.

[0003] For example, a sampling device for analyzing the density of rocks in geophysical exploration with the patent publication number of CN210269499U can artificially control the temperature and pressure in the sealed box by setting a pressure booster, a temperature changer and a displacement sensor in the sealed box, and the displacement sensor can measure and record the rock volume under different pressures and different temperatures, so as to achieve the purpose of measuring the true density of rocks deep in the earth's crust on the ground.

[0004] Although the above device can achieve the purpose of measuring the true density of rocks deep in the earth's crust on the ground by setting a pressure booster, a temperature changer and a displacement sensor in the sealed box, it cannot sample the rocks. The above device is used for the work after rock sampling. Before analyzing the rock density, it is necessary to sample the rock and soil to provide the corresponding rock materials for density measurement. Traditional rock collection is carried out by manual pressing or pushing, which is laborious, prone to fatigue after a long time, and prone to accidents, endangering the safety of workers. Therefore, we propose a new sampling device for analyzing the density of rocks in geophysical exploration. Content of the Utility Model

The U-shaped plates 602 are located on the top of the base 5. Sliding grooves 609 are provided at the left and right ends inside the U-shaped plates 602, and the moving seats 610 are arranged inside the sliding grooves 609.

[0033] The top ends of the threaded rods 607 penetrate through the U-shaped plates 602 and are connected to cam wheels 606. The cam wheels 606 are located on the left and right sides of the top of the U-shaped plates 602. A top plate 604 is installed above the cam wheels 606. A driving motor 605 is installed on the left side of the top of the top plate 604. The output end of the driving motor 605 is connected to the left cam wheel 606. The cam wheels 606 are connected by a transmission belt 603. Shading plates 608 are installed on the front and back sides of the bottom of the top plate 604.

[0034] As Figure 2As shown, it should be noted that: the driving motor 605 drives the cam wheel 606 to rotate. The cam wheel 606 is fixedly connected to the threaded rod 607. During the rotation of the cam wheel 606, the right cam wheel 606 is driven to rotate through the transmission belt 603. During the rotation of the cam wheel 606, the threaded rod 607 is driven to rotate.
