Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, and more specifically, to a geological exploration core sampling device. Background Art

[0002] In geological exploration, core sampling requires the use of a split-coring method to collect cores from drilled rock and minerals, with half sent for testing and the other half retained. Existing sampling methods typically rely on manual handheld cutting machines, which are unrepresentative and aesthetically pleasing. Handheld cutting machines also offer poor safety, poor representativeness, high labor intensity, and low efficiency. Other methods also utilize a fixed catheter to cut and extract samples, but these samples easily break when dropped to the ground, making them difficult to separate. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a geological exploration core sampling device, which can automatically sort and safely collect two samples.

[0005] Furthermore, a cutting groove is provided on the side wall of the conduit, the cutting groove passes through the conduit, the cutting groove is arranged above the water leakage hole, and the cutting machine passes through the cutting groove.

[0006] Furthermore, the conduit is arranged to be inclined, and the inclination angle of the conduit is greater than or equal to 5 degrees.

[0007] Furthermore, the sample separation mechanism also includes a collecting box, and two collecting boxes are provided, and the collecting boxes are arranged on both sides of the partition plate.

[0008] Furthermore, an opening and closing plate is rotatably connected to the middle of the collection box, a spring is provided on the bottom surface of the opening and closing plate, and the spring is connected to the inner wall of the collection box.

[0009] Furthermore, a discharge plate is slidably connected to the bottom side wall of the collection box, and the discharge plate is arranged below the opening and closing plate.

[0010] Furthermore, the sample delivery mechanism also includes a guide frame, the guide frame is arranged on the equipment platform, the sliding path is arranged at the rear end of the catheter, and the propeller is slidably connected to the guide frame.

[0011] Furthermore, the thruster is in a "7" shape, and a gap is provided at the bottom of the sliding track, and the lower part of the thruster can pass through the gap.

[0012] Furthermore, the waste water bucket is arranged below the water leakage hole, and the waste water bucket is connected to the bottom of the water storage bucket through a valve pipe.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, a geological exploration core sampling device includes: an equipment platform 1, which is provided with a water leakage hole 11; a core splitting mechanism 2, which is arranged on the equipment platform 1, and includes a guide tube 21 and a cutter 22; a sample dividing mechanism 3, which is arranged in front of the guide tube 21, and includes a partition plate 31, which is arranged in the middle of the front of the guide tube 21, and the end of the partition plate 31 facing the guide tube 21 is a pointed end; a sample feeding mechanism 4, which is arranged behind the guide tube 21, and includes a sliding path 41 and a propeller 42; a dust reduction mechanism 5, which is arranged around the equipment platform 1, and includes a water storage bucket 51, a waste water bucket 52 and a water spray pipe 53.

[0023] The sidewall of the conduit 21 is provided with a cutting groove 211, which passes through the conduit 21 and is located at the centerline of the conduit 21. The cutting groove 211 is located above the leak hole 11. The cutter 22 passes through the cutting groove 211, and the bottom of the cutter 22 is located below the conduit 21. The samples taken for geological surveys are cylindrical. The sample is placed in the conduit 21 for core sampling. When the sample enters the area where the cutting groove 211 is located, the cutter 22 splits the sample in half from the middle, and the cored sample becomes a semi-cylindrical shape.

[0024] The conduit 21 is tilted, and the tilt angle of the conduit 21 is greater than or equal to 5 degrees. When splitting the sample, the sample can slide down by itself under the action of gravity, saving the operator's thrust, reducing labor intensity, and improving cutting efficiency.

[0025] The sample separation mechanism 3 also includes two collection boxes 32, which are located on either side of the partition plate 31. When the cutter 22 completes splitting the core in the guide tube 21, the split slit slides out of the guide tube 21 and contacts the tip of the partition plate 31. The tip of the partition plate 31 causes the core sample to move to both sides of the partition plate 31, separating the experimental sample and the retained sample into two different collection boxes 32. After cutting, the samples are automatically separated, eliminating the need for manual sorting, reducing manpower and improving work efficiency.

[0026] like Figure 2 As shown, the center of the collection box 32 is rotatably connected to an opening and closing plate 321. A spring 322 is installed on the bottom surface of the opening and closing plate 321, which is connected to the inner wall of the collection box 32. After the cores are separated, they fall onto the opening and closing plate 321. The weight of the cores compresses the spring 322, causing the opening and closing plate 321 to open. The opening and closing plate 321 and the spring 322 work together to reduce the impact force generated when the sample falls into the collection box 32, reducing the chance of sample breakage and preventing dust generated by the core samples from continuously dispersing. The spring 322 exerts an upward rotational force on the opening and closing plate 321. A stop plate 324 is installed in the inner wall of the collection box 32. This stop plate 324 prevents the opening and closing plate 321 from opening upward, keeping it tightly closed when no core samples are present.

[0027] The bottom side wall of the collection box 32 is slidably connected to a discharge plate 323, which is arranged below the opening and closing plate 321. When the sample splitting is completed, the collection box 32 is sent to the laboratory. When the split sample needs to be taken out, the discharge plate 323 is opened to facilitate the removal of the sample from the bottom.

[0028] To safely push the sample into the conduit 21, a sample feeding mechanism 4 is used to push the sample to be split. The sample feeding mechanism 4 also includes a guide frame 43, which is located on the equipment platform 1. A sliding path 41 is located at the rear end of the conduit 21. The sliding path 41 is a circular tube that has been split in half. The sliding path 41 and the conduit 21 have the same inclination angle. When in use, the core is placed in the sliding path 41. The sliding path 41 is away from the cutting machine 22 so that the sample can be placed safely. The bottom of the pusher 42 is slidably connected to the guide frame 43. The operator holds the lower part of the pusher 42 and pushes the sample into the conduit 21.

[0029] The pusher 42 is in the shape of a "7". The bottom of the pusher 42 slides with the guide frame 43, and the top of the pusher 42 fits with the rear end face of the core. A notch is provided at the bottom of the sliding path 41, and the lower part of the pusher 42 can pass through the notch. Thus, the pusher 42 can smoothly deliver the sample into the catheter 21, and the operator's hand can be outside the catheter 21 to complete the pushing.

[0030] A wastewater bucket 52 is located below the leak hole 11. The wastewater bucket 52 is connected to the water storage bucket 51 below via a valve pipe 54. A water spray pipe 53 is located at the bottom of the water storage bucket 51. Two water spray pipes 53 are provided, one with its outlet facing the top of the cutting groove 211 and the other with its outlet facing the top of the collection box 32. The water spray pipes 53 are driven by a water pump. During core splitting, one water spray pipe 53 sprays water onto the cut surface to prevent dust from flying. The sprayed water flows into the wastewater bucket 52 through the leak hole 11. Once dust settles at the bottom of the wastewater tank, the valve is opened to allow some of the settled water to flow into the water storage bucket 51 for secondary use, saving water resources. The wastewater bucket 52 also requires regular cleaning. When the sample falls into the collection box 32, some dust is also generated. The other water spray pipe 53 sprays water to reduce this dust.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
