Description

Technical Field

[0001] The present invention relates to the technical field related to field storage of soil samples, and in particular to a field storage device for soil samples for geochemical exploration. Background Art

[0002] Geochemical exploration is an investigative method that discovers various types of geochemical anomalies by systematically measuring the geochemical properties of natural materials; natural materials can be rocks, gossans, soil, water, stream sediments, glacial deposits, plants or gases. The geochemical properties measured primarily focus on elemental content. The purpose of geochemical exploration has always been to locate mineral deposits through clues from geochemical anomalies. The application of geochemical exploration is gradually expanding, not only for prospecting but also providing valuable data for addressing environmental pollution, agriculture, animal husbandry, endemic diseases, and various geological issues. The Greater Khingan Range forest belt is a crucial component of my country's "Two Screens and Three Belts" ecological security strategy. Its northern section, the Songling District, is currently a vacant area for ecological geological surveys. Identifying the elemental content and spatial distribution patterns in the soil within this area will provide fundamental support for ecological protection and restoration in the region, necessitating soil sampling surveys in areas such as the Greater Khingan Range. Field soil sampling is typically stored in brown glass bottles, and after storage, the soil is often placed directly into portable cloth bags or storage boxes. However, during field travel, the bags often jostle with movement, causing sample bottles to collide with each other and easily break, thus affecting subsequent soil testing.

[0018] Furthermore, the sample bottle placement groove 8 is provided with a receiving plate 13 for receiving sample bottles in sliding connection therewith, and a connecting rod 15 perpendicular to it is provided at the bottom center of the receiving plate 13. One end of the connecting rod 15 extends to the stop groove 12 and is installed with a cold air baffle ring 16, which is sealed with the stop groove 12; a first spring 17 is sleeved on the connecting rod 15, and the first spring 17 is located between the bottom wall of the receiving plate 13 and the bottom wall of the sample bottle placement groove 8; a plurality of air inlet holes 14 that pass through the top and bottom are opened on the top surface of the receiving plate 13.

[0019] Furthermore, the protective mechanism includes a plurality of hinge shafts 18 arranged in the middle and lower part of the driving square groove 10, and the hinge shaft 18 is rotatably connected to the driving square groove 10.

At this time, the receiving plate 13 is pressed down synchronously, thereby compressing the first spring 17, and at the same time, through the connecting The connecting rod 15 presses down the cold air baffle ring 16, thereby making the cold air baffle ring 16 completely disengage from the stop groove 12. At this time, the cold air is injected into the sample bottle placement groove 8 through the cold air through hole 11, and then the sample bottle is stored at a low temperature; the synchronous receiving plate 13 moves downward to drive the first driving rod 20 that is always in contact with it to swing around the hinge shaft 18 as the center, and then compresses the second spring 22 until the receiving plate 13 contacts the stop block 21, and the box cover 2 is completely buckled; when the first driving rod 20 rotates, the second driving rod 23 swings synchronously, and then the clamping plate 24 and the first sponge pad 25 gradually tilt the sample bottle first, and then the four clamping plates 24 and the first sponge pad 25 gradually strengthen the clamping of the sample bottle, so that it is always in a stable state to avoid collision and damage; wherein the first spring 17 and the second spring 22 can reset the clamping plate 24 and the receiving plate 13 when the box cover 2 is opened to take out the sample bottle.
