Embodiment approach

[0051] As a specific embodiment of the present invention, the No. 1 block 22 is movably embedded with the No. 2 block 25, and the side of the No. 1 block 22 close to the drill bit 23 is provided with an end-to-end endless steel rope 221; The second block 25 and the position near the top of the drill bit 23 are fixedly connected with the endless steel rope 221 .

[0052] During work, the No. 1 block 22 internal activities are embedded with the No. 2 block 25, and the side of the No. 1 block 22 near the drill bit 23 is provided with an annular steel rope 221, and the annular steel rope 221 can move in the No. 1 block 22 but will not Break away from the No. 1 block 22; and the No. 2 block 25 and the position near the top of the drill bit 23 are fixedly connected with the annular steel rope 221; , so the ring-shaped steel rope 221 is pulled, and the ring-shaped steel rope 221 is fixedly connected with the top of the second block 25, so the ring-shaped steel rope 221 drives the mov...

specific Embodiment approach

[0053] As a specific embodiment of the present invention, the second block 25 is provided with a cavity 251 near the side wall of the drill bit 23 .

[0054] During work, this setting makes the inner diameter of the bottom of the cylindrical No. 2 block 25 smaller than the inner diameter of the cavity 251, and then when the sample enters the cavity 251, the sample in the cavity 251 is not easy due to the blocking of the end of the No. 2 block 25. Leakage ensures the stability of sampling by the sampling unit 2 and enables the sample to be taken out smoothly.

[0055] As a specific embodiment of the present invention, the ends of the No. 1 block 22 and the No. 2 block 25 away from the inside of the drill body 21 are provided with inclined surfaces.

[0056] During work, the end of No. 1 block 22 and No. 2 block 25 away from the inside of drill body 21 is provided with a slope, and in the process of drill bit 23 drilling into the ground, that is, when the drill bit 23 is not pul...

Abstract

The invention belongs to the technical field of mineral exploration and particularly relates to mineral geological exploration equipment. The equipment comprises a support and a sampling unit, wherein the sampling unit comprises a drill body, a first block, a drill bit and a pull rod; when the drill body reaches a proper depth; the drill body and the drill bit are controlled to stop rotating; at the moment, the pull rod is pulled, so the drill bit moves upwards in the first block, and the device is suitable for mineral geology with high moisture, high viscosity and softness; at the moment, the sample can enter the drill body by rotating the drill body or moving the drill body downwards, and then the sampling unit is taken out from the soil; sampling of mineral geological samples is completed; in this way, drilling and sampling are integrated, the sampling unit can conduct sampling at a specific depth in the sampling process, and a problem that samples are polluted by soil at other depths is avoided.

Description

technical field [0001] The invention belongs to the technical field of mineral exploration, in particular to a mineral geological exploration equipment. Background technique [0002] Geological and mineral exploration is based on advanced geological science theory, on the basis of a large number of field geological observations and collection of relevant geological data, using comprehensive geological means and methods such as geological survey, geophysical and chemical exploration, drilling engineering, etc., to obtain reliable geological and mineral resources. Information materials; including the identification of mineral reserves, ore quality, mining, selection, smelting and processing conditions, and technical and economic evaluation of ore deposits, so as to provide a basis for mine design and construction. [0003] Geological and mineral exploration is inseparable from drilling core sampling. In the process of most mineral geological sampling; if the sample layer is lo...
