Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coal seam exploration, and particularly relates to a coal seam exploration sampling storage device. BACKGROUND

[0002] In the field of coal resource exploration and development, coal sampling and its subsequent storage and transportation play a crucial role. This process not only requires accurate extraction of representative coal samples from complex coal seam structures according to established specifications and requirements for subsequent detailed analysis, testing, and identification, but also must ensure the integrity and original characteristics of the coal samples are not damaged during storage and transportation. As a direct carrier of key information such as coal classification, coal quality characteristics, variation rules, and process performance in the mining area or minefield, the importance of coal samples is self-evident. Therefore, designing and applying efficient and safe coal sampling storage boxes has become an integral part of the coal exploration technology system.

[0003] Traditional coal sampling storage box designs often focus on maximizing storage space utilization and improving coal sample protection performance. Typically, the interior of the storage box is divided into multiple storage cavities or slots with diameters close to the diameter of the coal sample. This design aims to optimize in two ways: first, by accurately matching the size of the coal sample, it can effectively reduce space waste during storage, allowing a single storage box to hold more coal samples, thereby improving the efficiency and cost-effectiveness of exploration operations; second, close size adaptation helps to limit the movement of coal samples during transportation, avoiding physical damage or composition changes caused by unnecessary collisions between the coal sample and the box, ensuring the complete preservation of the original characteristics of the coal sample. However, this extreme pursuit of space utilization and coal sample protection mechanism poses a significant challenge to the removal of coal samples. In the narrow storage cavity, it is often difficult for operators to directly access the coal sample, and even with auxiliary tools, factors such as limited visibility and operating space can lead to a time-consuming and labor-intensive coal sample removal process with high safety risks, especially finger injuries and other accidents.

[0004] In view of this pain point, the industry has made some improvement attempts, such as the design of a coal seam exploration sampling storage box shown in CN221069039U patent. The design installs an arc-shaped sampling plate in the storage tank, and is matched with a lifting bracket and a rectangular notch structure, aiming to simplify the coal sample taking process, while using rubber pads to enhance sealing and protection effects, and opening a cylindrical groove at the bottom of the storage tank to accommodate different shaped coal samples. This design alleviates the problem of difficult coal sample removal to some extent, and improves the convenience and safety of operation. However, in actual application, there are still some limitations: for example, although the arc-shaped sampling plate can closely fit the storage tank, reducing shaking, but after long-term storage or under complex transportation conditions, the aging and deformation of the rubber pad may affect the sealing performance; the design of the lifting bracket is convenient for lifting, but it is still awkward to operate in a narrow space, especially for small or irregularly shaped coal samples, the difficulty of taking out is still great; in addition, although the rectangular notch structure provides additional operating space, it may also become a hidden danger for coal sample debris accumulation, affecting the cleanliness and analysis accuracy of subsequent coal samples. Practical new type content
