Description

Technical Field

[0001] This utility model relates to the technical field of ore sampling equipment, specifically a sampling device for mining geological exploration. Background Technology

[0002] Mining geological exploration is a crucial foundational task in the early stages of mineral resource development. Its core objective is to determine the occurrence, distribution patterns, and mining value of mineral resources in the target area through systematic geological surveys and research, providing a scientific basis for subsequent mine design, development, and safe production. This process typically includes regional geological surveys, mineral prospecting, detailed exploration and investigation of mineral deposits, and resource reserve assessment.

[0003] In mining geological exploration, accurately obtaining representative rock samples is a crucial step in mineral resource assessment. Traditional mine sampling methods, limited by mine height, require grooved sampling. During this process, operators use a saw blade to cut four crisscrossing grooves into the rock wall, then manually hammer the sample within the grooved area to separate it from the bedrock. However, the impact load from hammering can easily cause microcracks or even complete fragmentation of the rock sample, severely affecting its integrity. Fragmented rock samples cannot accurately reflect the mineral composition and structural characteristics of the original rock, reducing the reliability of exploration data. Therefore, a new sampling device for mining geological exploration is needed to meet these requirements. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a propulsion component and a lifting component. After cutting four longitudinal and transverse grooves, the main body of the sampling device is placed at the grooves. The propulsion component inserts the propulsion base and rock sample lifting plate into the bottom groove. The lifting component then applies stress to the rock sample within the grooves. Under this stress, the portion of the rock sample that cannot be cut through the grooves fractures, causing the rock sample to fall onto the lifting plate, thus achieving complete separation of the rock sample. Compared to the traditional hammering method, this method achieves rock sample separation through controllable mechanical stress, avoiding the rock sample fragmentation problem caused by impact loads from hammering. This effectively improves the integrity and reliability of the sampling. The rock sample is then removed from the grooves and transferred to a collection box for direct collection, avoiding the need to pick up broken stones. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figures 1-5 This utility model provides a technical solution: a sampling device for mining geological exploration, including a sampling device body 1; to solve the problem that the saw blade can only cut four grooves (longitudinal and transverse), and the internal connection points need to be struck with a hammer to break the rock sample, which easily leads to the fragmentation of the rock sample and sample loss, a shell 2 is fixedly installed on the sampling device body 1. The sampling device body 1 has a collection box slot 3 for placing a collection box. A propulsion base 201 is slidably installed on the shell 2. A rock sample lifting plate 202 is raised and lowered on the propulsion base 201. The shell 2 has a propulsion mechanism inside. The method describes the propulsion components for the propulsion base 201 and the rock sample lifting plate 202. The propulsion base 201 is equipped with a lifting component for lifting the rock sample lifting plate 202. After cutting four longitudinal and transverse grooves in the mine wall, the target rock sample is located within the closed area enclosed by the four grooves. The main body 1 of the sampling device is placed at the groove, and the propulsion components insert the propulsion base 201 and the rock sample lifting plate 202 into the bottom groove. The lifting components then apply stress to the rock sample within the groove. Under the action of stress, the parts of the rock sample that cannot be cut through the groove fracture, thereby achieving complete separation of the rock sample. Compared with the traditional hammering method, this method achieves rock sample separation through controllable mechanical stress, avoiding the problem of rock sample fragmentation caused by impact loads generated by hammering, and effectively improving the integrity and reliability of sampling.

[0017] To feed the propulsion base 201 and the rock sample lifting plate 202 into the bottom groove, the propulsion assembly includes a propulsion motor 204. A propulsion motor groove 205 is provided at the bottom of the housing 2, and the propulsion motor 204 is fixedly installed in the propulsion motor groove 205. A propulsion screw 206 is fixedly installed at the output end of the propulsion motor 204. A sliding groove connector 207 is fixedly installed at the bottom of the propulsion base 201, and the sliding groove connector 207 is slidably installed in the propulsion motor groove 205. A propulsion screw hole 208 is provided on the sliding groove connector 207, and the propulsion screw 206 is installed in the propulsion screw hole 208. The propulsion screw hole 208 has threads, and the propulsion screw 206 is connected to the propulsion motor. The screw thread in the screw hole 208 is screwed into place, aligning the push base 201 and the rock sample lifting plate 202 with the groove below. The push motor 204 drives the push screw 206 to rotate. Under the screwing action of the push screw 206 and the push screw hole 208, the rotation of the push screw 206 causes the sliding groove connector 207 to slide in the push motor groove 205, thereby driving the push base 201 to move. The push base 201 drives the rock sample lifting plate 202 to move. During the movement, the rock sample lifting plate 202 inserts into the groove at the bottom. Then, the push motor 204 rotates in the opposite direction, driving the push base 201, the rock sample lifting plate 202 and the rock sample out of the groove.

[0018] To apply stress to the rock sample within the groove, causing controlled fracture separation between the rock sample and the bedrock within the groove, the lifting assembly includes a lifting motor 209, which is fixedly mounted on a propulsion base 201. A lifting screw 210 is fixedly mounted on the output end of the lifting motor 209 and rotatably mounted on the propulsion base 201. A limiting slide bar 211 is fixedly mounted on the propulsion base 201. A screw assembly 212 and a slide bar assembly 213 are fixedly mounted on the rock sample lifting plate 202. The lifting screw 210 is installed within the screw assembly 212, and the limiting slide bar 211 is installed within the slide bar assembly 213. The screw assembly 212 has a thread, and the lifting screw 210 is screwed into the thread of the screw assembly 212. The slide rod assembly 213 can slide along the limiting slide rod 211. The lifting motor 209 drives the lifting screw 210 to rotate. Under the screwing action of the lifting screw 210 and the screw assembly 212, the rotation of the lifting screw 210 drives the screw assembly 212 to move upward, thereby lifting the rock sample lifting plate 202 upward and applying stress to the rock sample in the groove. Under the action of stress, the part that cannot be cut in the groove will break, thereby achieving complete separation of the rock sample. The separated rock sample falls on the rock sample lifting plate 202.

[0019] A push plate 203 is slidably installed on the side of the outer shell 2. The collection box slot 3 and the push plate 203 are located on the two sides of the outer shell 2 respectively. A push rod 214 is slidably installed on the side of the outer shell 2. The push rod 214 is fixedly installed on the push plate 203. After the rock sample is removed from the groove, the push plate 203 transfers the rock sample into the collection box by pushing the push rod 214.

[0020] The working principle is as follows: When performing groove sampling in the mine, the weathered layer is first cleaned on the mine wall, and then four grooves are cut in both directions. The width of the grooves is slightly larger than the sum of the thickness of the propulsion base 201 and the rock sample lifting plate 202. The main body 1 of the sampling equipment is placed against the groove, and the propulsion base 201 and the rock sample lifting plate 202 are aligned with the groove below. The propulsion motor 204 drives the propulsion screw 206 to rotate. Under the rotation of the propulsion screw 206 and the propulsion screw hole 208, the rotation of the propulsion screw 206 causes the sliding groove connector 207 to slide in the propulsion motor groove 205, thereby driving the propulsion base 201 to move. The propulsion base 201 drives the rock sample lifting plate 202 to move. During the movement of the rock sample lifting plate 202, it inserts into the bottom groove, and the lifting motor lifts it. 209 drives the lifting screw 210 to rotate. Under the rotational action of the lifting screw 210 and the screw assembly 212, the lifting screw 210 rotates and drives the screw assembly 212 to move upward, thereby lifting the rock sample lifting plate 202 upward and applying stress to the rock sample in the groove. Under the action of stress, the part that cannot be cut in the groove will break, thereby achieving complete separation of the rock sample. The separated rock sample falls on the rock sample lifting plate 202, and then the propulsion motor 204 rotates in the opposite direction, driving the propulsion base 201, the rock sample lifting plate 202 and the rock sample to move out of the groove. After reaching the limit position, the push rod 214 on the side is pushed, so that the push plate 203 pushes the rock sample on the rock sample lifting plate 202 and pushes the rock sample into the collection box slot 3. The collection box slot 3 is pre-placed with a collection box.

[0021] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
