Description

Technical Field

[0001] The utility model relates to the technical field of geological mineral resources, in particular to a sampling device capable of sampling at different depths. Background Art

[0002] Geological minerals refer to all natural minerals or rock resources buried underground (or distributed on the surface or weathered or deposited) that can be used by humans. Minerals can be divided into metals, non-metals, combustible organic and other categories. They are non-renewable resources. Mineral exploration is a practical geology that studies the geological conditions of mineral formation and distribution, the occurrence laws of ore deposits, the characteristics of ore body changes, and the most effective methods for identifying and evaluating industrial ore deposits. It is highly comprehensive, practical, economic and policy-oriented, belongs to the category of economic geology, and is a comprehensive manifestation of geological science and economic science.

[0003] Different sampling tools are suitable for different soil types. In order to obtain qualified soil samples, appropriate sampling tools and methods should be selected according to the requirements for soil sample quality grade and soil type. Drilling sampling refers to the method of using a drill to sample underground or core samples in mines, which is more common in underground mining or downhole drilling.

[0004] General geological and mineral sampling requires sampling of soil or rock layers at different depths. However, the current sampling device has a relatively simple structure and uses a single drill bit and sampling tube for drilling and sampling. This makes it impossible to sample geological and mineral samples at different depths at the same time. Repeated disassembly and installation of the sampling tube will increase the sampling cost and the workload of the operator. In view of this, we propose a sampling device that can sample at different depths. Summary of the invention

[0026] In one embodiment of the utility model, the sampling assembly 4 includes an asynchronous reduction motor 41, the asynchronous reduction motor 41 is fixedly installed on the top of the N-shaped frame 3, a screw rod 42 is rotatably installed between the N-shaped frame 3 and the bottom plate 1, and the bottom output end of the asynchronous reduction motor 41 is fixedly connected to the top of the screw rod 42. When the asynchronous reduction motor 41 is started, the screw rod 42 is rotated between the N-shaped frame 3 and the bottom plate 1. A threaded block 43 is threadedly installed on the outer side of the screw rod 42, and the side wall of one end of the threaded block 43 slides and fits the inner wall of the N-shaped frame 3. The threaded block 43 is threadedly installed on the outer side of the screw rod 42. A rectangular plate 44 is fixedly installed at the other end of the block 43, and the outer wall of the end of the rectangular plate 44 away from the threaded block 43 slides and fits the inner wall of the N-shaped frame 3, so that the threaded block 43 drives the rectangular plate 44 to move up and down. Further, a limit rod 5 is fixedly installed between the bottom plate 1 and the top of the N-shaped frame 3, and the arc-shaped outer wall of the limit rod 5 slides and fits the arc-shaped inner wall of the rectangular plate 44. A fixed column 45 is fixedly installed at the bottom of the rectangular plate 44, and a side plate 46 is fixedly installed on the outside of the fixed column 45, so that the fixed column 45 drives the side plate 46 The side plate 46 moves up and down. When sampling is to be performed, the side plate 46 moves downward to the target height. A hydraulic rod 47 is fixedly installed at the bottom of the side plate 46. A sampling motor 48 is fixedly installed at the bottom of the hydraulic rod 47. Further, the side plate 46, the hydraulic rod 47, the sampling motor 48, the sampling barrel 49 and the drill bit 410 are arranged in three groups, and the three groups of side plates 46, hydraulic rods 47, sampling motors 48, sampling barrels 49 and drill bits 410 are arranged in a circular array with equal spacing, with the center of the circular cross section of the fixed column 45 as the center of the array. 410 is connected with the inside of the sampling barrel 49, so that different groups of hydraulic rods 47 are started respectively, so that the sampling motor 48 moves downward to different heights. The sampling barrel 49 is fixedly installed on the output end at the bottom of the sampling motor 48 through fasteners, and a drill bit 410 is fixedly installed on the bottom of the sampling barrel 49. Therefore, by cooperating with the sampling barrel 49 and the drill bit 410, geological and mineral samples at different depths can be sampled simultaneously. It is worth noting that there are multiple groups of sampling barrels 49 at the bottom of a single group of sampling motors 48, which are connected head to tail through fixings.

[0027] In one embodiment of the utility model, the lubrication assembly 8 includes a triangular block 81, a triangular block 81 is fixedly installed on the top of the rectangular plate 44, and an L-shaped block 82 is fixedly installed on the outer wall of the triangular block 81. Further, when the rectangular plate 44 moves upward, the triangular block 81 and the L-shaped block 82 are driven to move upward synchronously. An oil storage barrel 83 is clamped inside the top of the N-shaped frame 3, and a cylinder 84 is slidably installed inside the bottom end of the oil storage barrel 83. The cylinder 84 is hollow inside, and the top is closed, and the bottom is provided with an opening. The cylinder 8 The outer side of the bottom end of the L-shaped block 82 is fixedly connected to the center of the fixed block 85. Furthermore, a thin rod 86 is fixedly installed on the top of the fixed block 85, and a disc block 87 is fixedly installed on the top of the thin rod 86. The bottom of the disc block 87 fits the lower surface of the top of the N-shaped frame 3, so that the top of the L-shaped block 82 will be close to and press the fixed block 85 upward, so that the thin rod 86 slides upward inside the top of the N-shaped frame 3. A tight spring 88 is sleeved on the outer side of the thin rod 86, so that the tight spring 88 is compressed and deformed. Further, the L-shaped block 82 2. Two groups of thin rods 86 and close springs 88 are provided, and the two groups of L-shaped blocks 82, thin rods 86 and close springs 88 are symmetrically arranged at both ends of the fixed block 85, so that the cylinder 84 can move up and down more stably.

On the contrary, when the L-shaped block 82 moves downward, the clamping spring 88 restores its deformation, so that the cylinder 84 is reset, and the lubricating oil in the oil storage barrel 83 will not flow out.

[0028] Working principle: When the asynchronous reduction motor 41 is started, the screw rod 42 rotates between the N-shaped frame 3 and the bottom plate 1, so that the threaded block 43 drives the rectangular plate 44 to move up and down, thereby cooperating with the fixed column 45 to drive the side plate 46 to move up and down. When sampling is to be carried out, the side plate 46 moves downward to the target height, thereby starting different groups of hydraulic rods 47 respectively, so that the sampling motor 48 moves downward to different heights, thereby cooperating with the sampling tube 49 and the drill bit 410, geological and mineral samples of different depths can be sampled at the same time. Furthermore, when the rectangular plate 44 moves upward, it drives the triangular block 81 and the L-shaped block 82 to move upward synchronously, so that the top of the L-shaped block 82 will be close to and move toward the target height. The upper extrusion fixing block 85 causes the thin rod 86 to slide upward inside the top end of the N-shaped frame 3, and the clamping spring 88 is compressed and deformed, so that the cylinder 84 moves upward inside the bottom end of the oil storage barrel 83, so that the oil inlet groove 89 enters the oil storage barrel 83, so that a part of the lubricating oil enters the cylinder 84, and then drips into the inclined groove 810 through the opening at the bottom end of the cylinder 84, thereby lubricating the screw rod 42, and then reducing the effect of the reduced sampling efficiency caused by the jamming of the threaded block 43 due to rust. On the contrary, when the L-shaped block 82 moves downward, the clamping spring 88 recovers its deformation, so that the cylinder 84 is reset, and the lubricating oil in the oil storage barrel 83 does not flow out.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
