An auxiliary tool for studying geological sedimentary facies

Abstract

The invention provides an auxiliary tool for learning geologic sedimentary facies, and relates to a learning auxiliary tool. A chemical reagent guiding device is arranged at the upper end of a holdingrod, a through hole which penetrates through the holding rod is formed in the holding rod, and a chisel shovel and a sampling shovel are arranged at the lower end of the holding rod, and chisel shovel and the sampling shovel are detachable and replaceable. The chisel shovel is composed of a connecting head, a connecting plate and a column-shaped shovel. A connecting plate is arranged at the lowerend of the connecting head, and the column-shaped shovel is arranged at the lower end of the connecting plate. The sampling shovel is composed of a connecting head B, a plurality of vertical plates and a plurality of inclined plates. A rotating rod is arranged at the lower end of a reset spring. A drill bit is arranged at the lower end of the rotating rod. The auxiliary tool for learning the geologic sedimentary facies can help students safely and conveniently to collect surface rock and mineral samples as well as deep underground rock and mineral samples and massive rock and mineral samples,is more conducive to students observing the structure, color and form of rock and mineral samples and displacement, fault and other bedding characteristics, so that support is provided for students to analyze regional geological information and sedimentary facies information.

Description

technical field [0001] The invention relates to a learning tool, in particular to an auxiliary tool for studying geological sedimentary facies. Background technique [0002] It is well known that field geological practice, as an important practical part of geological teaching, is not only an extension of classroom theory teaching, but also an important test method for teaching effect, which plays a significant role in improving students' comprehensive quality and promoting the close integration of theoretical knowledge and practice. important role. Structural geology field practice is a very important link in the practical teaching of resource exploration engineering. It not only plays an important role in the consolidation and understanding of students' geological knowledge, or the basic training of field geological work, but also cultivates practical ability and It is one of the effective ways for innovative oil and gas exploration and development talents.

Problems solved by technology

[0004] In the field practice of structural geology, tools for geological practice are necessary for students to collect rock and mine samples. However, most of the tools for geological practice carried by students are geological hammer, geological compass, magnifying glass, multi-purpose shovel, hydrochloric acid, etc., among which When collecting rock ore samples, tools such as hammers and shovels are mainly used. The current geological practice tools are single and simple in structure, which is not much different from the common hammers or shovels in daily life. There is no special design for geological practice to collect rock ore. There are many problems in the process of geological practice with traditional tools such as hammers and shovels:

[0005] (1) It can only be collected for the soil on the surface of the stratum, and cannot collect rock ore samples in deep underground areas

In some soft or loose areas, you can use a shovel to collect rock ore samples. When collecting in hard rock areas, you need to chisel the surface rock with a hammer to collect some fragments or crushed rock samples, while crushed or small Granular rock and mine specimens not only cause damage to rock and mine specimens, but also are very inconvenient for students to observe bedding characteristics such as rock structure, color, shape, displacement, faults, and sedimentary facies, which is not conducive to the analysis and observation of geological conditions for students In addition, if it is necessary to collect deep underground rock and mineral samples, traditional geological tools will be stretched. However, collecting deep rock and mineral samples is very necessary in geological learning. Students can analyze them better by collecting enough rich rock and mineral samples For the texture characteristics of rock formations, traditional geological tools with simple structures cannot help students obtain rock and mineral samples that are larger in size and suitable for observing bedding characteristics, as well as rock and mineral samples with richer and more complete vertical geological structure information on the surface

[0006] (2) At present, in geological practice, tools such as Luoyang shovel are also used to collect rock and mineral samples. However, when Luoyang shovel is collected deep underground, the shovel is pulled out after mashing and then mixed materials such as soil are taken out, which are generally sample debris. , and can only observe deep soil information, cannot obtain rock information, and cannot meet the needs of geological learning for the analysis and interpretation of structural features and the acquisition of information on the formation and distribution of various resources on the surface

[0007] (3) There are potential safety hazards when the hammer hits, students are easily injured and gravel is splashed, which is easy to injure other students

[0008] To sum up, in the face of the current colleges and universities' continuous emphasis on geological field practice teaching, the traditional tools for geological practice cannot help students collect complete rock and mine samples to learn geological related knowledge well, and there is an urgent need for a special tool for geological practice. A tool for collecting rock and mine specimens to help students learn geological phenomena and sedimentary facies in field geological practice areas
