Description

Technical Field

[0001] The present application relates to the technical field of mineral exploration, and more specifically, to a casing shoe for mineral exploration casing. Background Art

[0002] Mineral exploration is a geological work that applies effective exploration techniques and methods to provide reliable ore reserves and necessary geological, technical and economic data for mine design after general survey and detailed investigation of ore deposits that have been determined to have industrial value. It is also called ore deposit exploration. However, the existing casing shoes for mineral exploration casings have poor sealing performance during actual use, and cannot effectively block the soil on the inner wall of the mine, resulting in soil entering the casing through the inside of the casing shoes. It takes a lot of time to clean the soil inside the casing shoes and the casing, which affects the efficiency of mineral exploration and is not conducive to actual use. In addition, the device cannot discharge the soil that accidentally enters the casing shoes, which easily causes a large amount of soil to accumulate inside the casing shoes. Not only does it take a lot of manpower to disassemble and clean it later, but it also affects the tightness of the connection between the casing shoes and the casing, and the casing shoes are prone to loosening, which is not conducive to safe use.

[0003] The document with prior art publication number CN 214498948 U provides a casing shoe for mineral exploration casing. The device is provided with a closing-shaped movable groove that matches the size of a sealing ball sleeve at the upper end of the baffle plate, so that the sealing ball sleeve can be tightly embedded in the movable groove at the upper end of the baffle plate, thereby improving the sealing inside the baffle plate, thereby strengthening the sealing of the device, and can effectively block the soil on the inner wall of the mine, effectively preventing the soil from entering the exploration equipment through the inside of the casing shoe, and there is no need to spend a lot of time cleaning the soil inside the casing shoe, thereby ensuring the work efficiency of mineral exploration and facilitating practical use.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: after the sealing ball sleeve is separated from the spoiler, when there are sludge particles in the sleeve, when the pressure in the tube is reduced, the spring rebounds and the sealing ball sleeve is attached to the spoiler. When there are sludge particles between the two, the sealing performance of the sealing ball sleeve and the spoiler is reduced.

[0005] In view of this, we propose a casing shoe for mineral exploration casing. Utility Model Content
