Description

Technical Field

[0001] The utility model relates to the technical field of core sampling for mineral exploration, in particular to a storage device for drilled core samples. Background Art

[0002] In the process of developing solid mineral resources, it is necessary to use a coring drill to drill core samples of underground rocks. Laboratory analysis of the rocks is carried out to determine the geological characteristics of the area and whether there is a possibility of mineral distribution. When drilling core samples of rocks with a rock drill, the inner diameter of the rock drill is 113 mm and the depth is 20 cm. When the core samples are drilled, the sides of the core samples will be worn. In order to be able to take out a core of sufficient length, the core sample will be slightly longer.

[0003] Although existing sample storage devices have solved certain problems, they still have the following disadvantages:

[0004] The existing sample storage device places the core sample directly inside the container for storage. The length and thickness of the sample are the same, which is not uniform. The sample is prone to shaking after placement, which can easily cause the integrity of the sample to be destroyed during transportation. The existing sample storage device cannot be adjusted according to the sample to reduce the shaking of the sample during transportation. Utility Model Content

[0035] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Example 1:

[0038] like Figures 1 to 6 As shown, this embodiment proposes a storage device for drill core samples, including a shell 1, a slider 2, an adjustment mechanism 3, a control component 4, a positioning mechanism 5, an installation cavity 6, a sliding slot 7, a sealing cover 8, a connecting slot 9 and a splint 10 arranged at the front, back and both sides of the shell 1.

[0039] Among them, the interior of the shell 1 is a cylindrical space with a circular opening at the upper end. A sealing cover 8 is provided on the upper side of the exterior of the shell 1. The lower end of the sealing cover 8 is a circular sealing block that blocks the upper opening of the shell 1, and the sealing block is threadedly connected to the side wall at the top of the inner top of the shell 1. A connecting slot 9 is provided at the center position of the upper end of the sealing cover 8. A movable rod 501 that can move up and down is provided inside the connecting slot 9. A stop block 503 is fixedly connected to the upper end of the movable rod 501, and a pressure block 502 is fixedly connected to the lower end. By moving the pressure block 502 downward, a certain pressure is applied downward to the ore core sample inside the shell 1 to fix the ore core sample in the vertical direction.

[0040] In order to allow the pressing block 502 to have downward pressure, an extrusion spring 504 is placed on the outside of the movable rod 501. The extrusion spring 504 is between the upper side of the pressing block 502 and the lower side of the sealing cover 8, which squeezes the pressing block 502 downward. The stopper 503 connected to the upper end of the movable rod 501 prevents the movable rod 501 from escaping from the inside of the connecting slot 9. However, when the core sample taken out of the core tube is taken out from the inside of the core tube, the side of the sample may be scratched or affected by the internal structure of the core. The core sample may be smaller than the inner diameter of the core tube, so the core sample needs to be clamped and fixed on the side. The inner diameter of the tube is 113 mm and the length is 20 cm. When drilling cores with the drill pipe, as much as possible will be drilled to fill the interior of the drill pipe with cores. The length of the core sample taken out is greater than 20 cm. Therefore, when the extrusion spring 504 on the movable rod 501 is not squeezed and compressed, the distance between the lower side of the pressure block 502 and the upper side of the turntable 302 set on the lower side of the inner side of the shell 1 is 20 cm. After placing the sample into the interior of the shell 1, the sealing cover 8 is covered, and the pressure block 502 will be squeezed upward, and the extrusion spring 504 is compressed, which produces a certain downward pressure on the pressure block 502.

[0041] The front and back of the lower end of the inner shell 1 and the sides are provided with sliding slots 7. This application takes four sliding slots 7 as an example. A slider 2 is provided inside each sliding slot 7. The slider 2 can only slide inside the sliding slot 7. Four evenly distributed toggle slots 303 are provided on the upper side of the turntable 302. The toggle slots 303 can drive the adjusting rods 301 inside them to move closer to or away from each other by rotation. The lower end of the adjusting rod 301 and the upper side of the slider 2 are fixedly connected together. The upper end of the adjusting rod 301 is fixedly connected to a splint 10 with a fan-shaped cross-section. The splints 10 are combined into a circular shape. Driven by the adjusting rod 301, the toggle slots 303 can move closer to or away from each other to clamp the core sample placed inside the shell 1. When the four splints 10 are farthest away from each other, the inner wall of the splint 10 forms a circle with a diameter of 113 mm. After the splints 10 are close to each other, they clamp the side of the core sample.

[0042] In order to facilitate the control of the rotation of the turntable 302, an installation cavity 6 is opened inside the bottom end of the shell 1, and the interior of the installation cavity 6 and the interior of the shell 1 are connected through the internal through-connection of the sliding slot 7. The rotating shaft at the lower end of the turntable 302 extends to the interior of the installation cavity 6, and a worm gear 401 is fixedly connected to the bottom end of the rotating shaft of the turntable 302. A worm 402 is provided inside the installation cavity 6, and the two ends of the worm gear 402 are respectively connected to the front and rear rotation inside the installation cavity 6, and a control knob 403 is rotatably connected to the lower side of the external front end of the shell 1. The control knob 403 is fixedly connected to the rotating shaft at the front end of the worm gear 402. The worm gear can drive the worm gear, and the worm gear cannot drive the worm gear in turn, so that the turntable 302 can be self-positioned.

[0043] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
