Description

Technical Field

[0001] The utility model relates to the technical field of rock sampling, in particular to a geological exploration rock sampling device. Background Art

[0002] The purpose of collecting rock specimens is to observe and study the structure, texture, mineral composition and their symbiotic combination of rocks, study the metamorphism and alteration phenomena of minerals, determine the names of rocks and minerals, and compare strata and rocks.

[0003] In Chinese Patent No. 202222903092.7, the utility model discloses a soil exploration sampling device, including a hand-held drill and a drill pipe. The drill pipe is installed at the output end of the hand-held drill. A sampling drill bit is assembled and connected to the lower end of the drill pipe. The lower end of the sampling drill bit is of an open design. A connecting head is spirally installed at the upper end of the sampling drill bit. The upper part of the connecting head is assembled and connected to the drill pipe. The utility model relates to the technical field of geological exploration. The lower end of the sampling drill bit is of an open design and a ring-shaped stepped boss is arranged at the bottom. A sampling core pipe is inserted into the sampling drill bit and is limited and fixed by the connecting head. The connecting head is connected to the drill pipe. Then, the sampling drill bit is drilled into the sampling position by using the hand-held drill. During the drilling process, the soil sample enters the sampling core pipe inside the sampling drill bit. After sampling, the connection between the drill pipe and the connecting head is released, the connecting head is removed, and then the sampling core pipe is taken out.

[0004] The existing hand-held geological exploration rock sampling equipment has the problems that when drilling and sampling, a downward pressing force needs to be provided for the drill pipe. For a hand-held sampling device, usually only the weight of the sampling personnel themselves can be relied on to press the drill pipe downward. For some relatively thin and light-weight operators, the drilling may be slow due to insufficient downward pressing force. And during the drilling process, the drill pipe rotates at a high speed with the rock, and the friction force is too large, generating a large amount of heat. If the heat is too high and difficult to dissipate, it will damage the drill pipe.

[0005] Therefore, a geological exploration rock sampling device is proposed for the above problems. Summary of the Utility Model

[0026] Embodiment 1

And a pressing-down assembly 3 is installed on the top of the cooling and dust removal assembly 2. During drilling, the water tank on the top can provide a downward pressure for it to assist the drill pipe to drill downward, which is convenient to improve the drilling efficiency.

[0028] As Figure 5As shown in the figure, a geological exploration rock sampling device, the downward pressing component 3 is used to provide an auxiliary downward pressing force during the drilling process, and at the same time can cool the motor. The downward pressing component 3 includes a lower pressing plate 301. A downward pressing handle 302 is fixedly connected to the side of the lower pressing plate 301. An electric motor bearing shaft 303 is rotatably connected inside the lower pressing plate 301. A high-torque servo motor 304 is installed at the top of the electric motor bearing shaft 303. Heat dissipation fins 305 are installed on the outer wall of the high-torque servo motor 304. A water storage tank 306 is closely attached to the outer wall of the heat dissipation fins 305. A water pump 307 is installed on the side of the water storage tank 306. A threaded interface 308 is connected to the end of the water pump 307. A threaded joint 309 is threadedly connected inside the threaded interface 308. And a water delivery hose 310 is connected to the end of the threaded joint 309. The water delivery hose 310 forms a communication structure with the water pump 307 through the threaded joint 309 and the threaded interface 308. The water storage tank 306 and the heat dissipation fins 305 form a snap-fit structure. And the material of the surface of the water storage tank 306 in contact with the heat dissipation fins 305 is set as an aluminum-copper alloy material. The water storage tank 306 is arranged at the top of the handheld drilling sampling device. During the drilling process, it can assist in providing a downward force, facilitating the improvement of the downward drilling efficiency. And the water storage tank 306 is snap-fitted outside the high-torque servo motor 304, and the position in contact with it is set as an aluminum-copper alloy, which is convenient for assisting the high-torque servo motor 304 to dissipate heat. The structure is simple and serves two purposes at once.

[0029] As Figure 4 As shown in the figure, a geological exploration rock sampling device, the cooling and dust removal component 2 is used to spray water flow at the contact position between the drill rod and the rock while drilling and sampling, cool and lubricate it, and reduce the wear of the drill rod. The cooling and dust removal component 2 includes an annular water distribution pipe 201. Nozzles 202 are installed at the bottom of the annular water distribution pipe 201. A receiving block 203 is fixedly connected to the side of the annular water distribution pipe 201. A limiting support rod 204 is fixedly connected to the bottom of the receiving block 203. And a support foot 205 is fixedly connected to the bottom end of the limiting support rod 204. A telescopic rod 206 is fixedly connected to the top of the receiving block 203. And a spring 207 is nested outside the telescopic rod 206. The nozzles 202 are arranged at equal angles at the bottom of the annular water distribution pipe 201. And the annular water distribution pipe 201 forms a communication structure with the lower pressing plate 301. The receiving block 203 forms an elastic structure with the lower pressing plate 301 through the spring 207. And there are two receiving blocks 203 symmetrically arranged about the vertical central axis of the annular water distribution pipe 201. The annular water distribution pipe 201 is wound around the outside of the rock sampling drill rod 105. And under the interaction of the spring 207 and the limiting support rod 204, it can maintain a roughly constant distance from the rock, thereby facilitating the spraying of water flow at the contact position between the drill rod and the rock, cooling the drill rod, and at the same time reducing the friction between the drill rod and the rock, which is convenient for protecting the drill rod and reducing the wear it suffers.

[0030] As shown Figure 3 in the figure, a geological exploration rock sampling device, the drilling and sampling assembly 1 is used to rotate at a high speed driven by a motor and drill into the rock for sampling. The drilling and sampling assembly 1 includes a drill pipe joint 101. A connecting clamping column 102 is fixedly connected to the side of the drill pipe joint 101, and a connecting clamping block 103 is fixedly connected to the end of the connecting clamping column 102. The outside of the connecting clamping column 102 is snap-connected with a connecting clamping groove 104, and a rock sampling drill pipe 105 is integrally connected to the outside of the connecting clamping groove 104. The rock sampling drill pipe 105 and the drill pipe joint 101 form a detachable structure through the connecting clamping column 102 and the connecting clamping groove 104, and the shape of the connecting clamping groove 104 is set in an "L" shape. The rock sampling drill pipe 105 is connected to the motor bearing shaft 303 through the drill pipe joint 101 and can be disassembled, which is convenient to replace the rock sampling drill pipe 105 with a suitable length according to the depth of the drilling and sampling required, and only needs to align the groove and rotate, and the operation is simple and convenient.

[0031] Working principle: Before sampling, water can be found near the sampling site and the water storage tank 306 can be filled. Then, the water storage tank 306 is snap-fitted outside the high-torque servo motor 304. The material of the surface where the water tank contacts the heat dissipation fins 305 is set as an aluminum-copper alloy material, which has excellent heat conduction performance. The heat generated by the high-torque servo motor 304 during operation can be transferred to the water inside the water storage tank 306 through the heat dissipation fins 305, thereby assisting the high-torque servo motor 304 in heat dissipation. Then, the threaded joint 309 is rotated and connected to the threaded interface 308;

[0032] During drilling, according to the depth of the drilling and sampling required, a rock sampling drill pipe 105 with a suitable length is selected. The top of the connecting clamping groove 104 is aligned with the connecting clamping column 102 and snapped upward, so that the connecting clamping column 102 is stuck at the end after the turn at the bottom of the L-shaped connecting clamping groove 104. The rotation direction of the motor bearing shaft 303 is opposite to the direction of the extension of the bottom turn of the connecting clamping groove 104. Therefore, the connecting clamping column 102 will not come out of the connecting clamping groove 104 during rotation;

[0033] Then, hold the downward pressing handle 302, align the rock sampling drill bit 106 with the rock to be sampled, and start the high-torque servo motor 304. The output end of the high-torque servo motor 304 drives the rock sampling drill pipe 105 to rotate through the motor bearing shaft 303 and the drill pipe joint 101, and gradually drills the rock sampling drill pipe 105 into the rock for sampling;

[0034] During drilling, start the water pump 307, and input the water inside the water storage tank 306 into the annular water distribution pipe 201 through the water delivery hose 310, and spray it onto the contact area between the rock sampling drill rod 105 and the rock through the nozzle 202. Moreover, the limit support rod 204 supports on the rock, and under the action of the top spring 207, it presses the annular water distribution pipe 201 downward, and cooperates with the limit support rod 204 to keep the annular water distribution pipe 201 at a fixed height.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
