Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a sampling method for geological exploration and mapping. Background Art

[0002] Geological and mineral exploration and mapping is also called geological and mineral mapping. It is the general term for all mapping work involved in the exploration of geological and mineral resources and the preparation of exploration results maps. The commonly used sampling equipment for geological and mineral exploration and mapping is a drilling rig, which is used to drill holes and take samples with a sampling drill bit. Most sampling drills are relatively heavy, and in the process of geological and mineral exploration and mapping, the road conditions are mostly poor, making it inconvenient and laborious to carry and turn over the sampling drill. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN216645918U, a geological and mineral exploration, surveying and sampling equipment, includes: a drill body, a sampling drill rod, a base, a slot, a handle, a hanging ring, a shoulder strap, a hook, and a hanging block; the sampling drill rod is connected to the output shaft at the bottom of the drill body through a coupling; two bases are provided on the front side of the lower end of the drill body, and the two bases are bolted to the drill body, and a slot is opened on the opposite ends of the two bases; a handle is fixed on the left and right sides of the upper end of the drill body by bolts; a hanging ring is threadedly connected to the middle position of the top of the drill body; a shoulder strap is provided on the front side of the drill body; the utility model improves a geological and mineral exploration, surveying and sampling equipment, has the advantages of reasonable structure, convenient carrying and turnover of the drill body, relatively labor-saving, convenient installation and disassembly, and convenient use of a shoulder strap, thereby effectively solving the problems and shortcomings of the existing device.

[0004] Although the equipment in the above documents can be conveniently carried and used for drilling in geological exploration, it still has obvious defects in actual use, such as: Although the device is convenient to carry, it can only perform the single function of drilling. After drilling a deeper hole each time, the staff cannot easily take out a part of the sample from the bottom of the hole again. An additional sampling tool is required. This tool usually has a certain length requirement, which is not convenient for the staff to carry and will make the whole sampling process cumbersome: Therefore, a sampling device for geological survey and mapping that can drill holes and also conveniently take samples is now designed to solve such defects.

Beneficial Effects

[0016] The present invention provides a sampling method for geological survey and mapping. Compared with the existing technology, it has the following beneficial effects: (1) The sampling method for geological survey and mapping uses a material unlocking mechanism and a drilling sampling mechanism in combination. The two mechanisms can be arranged so that when in use, the cylinder is first used to push the auger blade down to drill holes, and then the circular frame is raised to complete the docking with the sampling tube. After the circular frame is lowered again, the sampling tube can take out the sample in the hole. After the sample is taken out, the linkage between the structures can be used to move the material receiving box to the bottom of the sampling tube for material holding. The whole process is effective and quick, reducing the operation of the staff and facilitating use.

[0017] (2) The sampling method for geological survey and mapping is to install a driven rod and an auger blade inside a sampling tube, and install a gear plate on the surface of the driven rod to cooperate with a toothed ring, and use it in conjunction with a bevel block and a rectangular flat groove. The arrangement of these structures enables the cylinder to first descend alone to drill and punch holes, and then the driven rod can be connected to the sampling tube by power after rising, and then descend again to take samples. The whole process is quick and convenient, and does not require staff to dock the equipment, and can effectively take out samples from deep in the hole.

[0018] (3) The sampling method for geological exploration and mapping is to install a transverse rod and a first bevel gear at the rear of the side platform, and use it in combination with a threaded tube, a threaded rod and an arc-shaped pressure plate. The arrangement of these structures can utilize the lifting and lowering of the side sliding rod to make the arc-toothed plate drive the two first bevel gears to rotate, thereby allowing the arc-shaped pressure plate to descend a certain distance, so that the subsequent L-shaped plate frame can rise and reset to separate the inclined surface block from the rectangular flat groove, making it convenient to discharge the sample and carry out the next drilling work.

[0019] (4) The sampling method for geological survey and mapping is to install a return frame plate on the inner side of the sliding groove, and to arrange a tooth plate that can be raised and lowered inside the return frame plate, and to use it in conjunction with a second gear cylinder. The arrangement of these structures can, after the button is triggered, use the second gear cylinder to move the material receiving box to the bottom of the sampling cylinder to hold the material, and after the material is held, use the weight of the sample to press down the tooth plate to separate it from the second gear cylinder, so that the return frame plate rebounds and resets, making it convenient for the staff to take the material.

DETAILED DESCRIPTION

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-11 The present invention provides a technical solution: a sampling method for geological exploration and mapping, which specifically comprises the following steps: S1. Equipment movement: Move the material unlocking mechanism 1 to a specified position and fix it; S2, geological drilling: after the position is fixed, the cylinder 201 in the drilling sampling mechanism 2 is started to push the second motor 203 and the auger blade 207 down to perform drilling; S3, structural docking: after drilling is completed, the cylinder 201 is started to rise, so that the gear plate 208 and the tooth ring 205 are meshed to complete the docking; S4, geological sampling: after the structural docking is completed, the cylinder 201 pushes the sampling tube 204 down to take samples; S5, sample placement: After the sampling is completed, the sampling tube 204 rises and discharges the sample inside to the inner side of the receiving box 127.

[0024] The above-mentioned sampling method for geological exploration and mapping has the following more specific steps: S1. Equipment movement: Move the material holding unlocking mechanism 1 to a specified position and fix it, and align the lifting slot 112 with the position where sampling is required; S2, geological drilling: after the equipment is fixed, the cylinder 201 is started to push the circular frame 202 down, and the circular frame 202 drives the second motor 203, the driven rod 206 and the auger blade 207 to extend downward from the inside of the sampling tube 204, and at the same time, the second motor 203 is started to drive the auger blade 207 to rotate, and the auger blade 207 is drilled after it contacts the ground; S3, structural docking: after the auger blade 207 drills a hole, the cylinder 201 pulls the second motor 203, the driven rod 206 and the auger blade 207 to rise, so that the auger blade 207 retracts to the inner side of the sampling tube 204 and continues to rise until the gear plate 208 meshes with the toothed ring 205, and the cylinder 201 rises to the limit position and stops. At this time, the auger blade 207 is located at the upper part of the inner side of the sampling tube 204, and when the circular ring frame 202 rises, the side slide bar 209 will also drive the rectangular bullet frame 210, the inclined surface block 211 and the retraction box 213 to rise together, until the inclined surface block 211 is inserted into the inner side of the rectangular flat groove 107 to complete the docking, and the arc tooth plate 214 is located at the upper part of the first gear tube 110 and uses the characteristics of the sixth spring 215 to not mesh with the first gear tube 110 and drive it to rotate; S4, geological sampling: After the structural docking in step S3 is completed, the cylinder 201 is started again and pushes the ring frame 202 to descend. At this time, when the ring frame 202 descends again, it will use the docking of the inclined block 211 and the rectangular flat groove 107 to drive the L-shaped plate frame 104, the guide vertical rod 103 and the sampling tube 204 to descend together. At the same time, when the second motor 203 is started, it will use the meshing of the gear plate 208 and the toothed ring 205 to drive the sampling tube 204 to rotate together. After the sampling tube 204 contacts the ground, it rotates The sample is cut by rotating, and stops after entering the sampling tube 204. After the side sliding rod 209 follows and descends for a certain distance, the arc tooth plate 214 drives the first gear tube 110 and the traverse rod 108 to rotate. The rotation of the traverse rod 108 also drives the first bevel gear 109 to rotate, so that the second bevel gear 120 drives the threaded tube 115 to rotate under the meshing of the first bevel gear 109. After the threaded tube 115 rotates, the curved top frame 117 drives the arc pressure plate 118 to descend for a certain distance under the limitation of the vertical guide plate 119. S5, sample holding: after the sample cutting is completed and is inside the sampling tube 204, the cylinder 201 starts to push the circular frame 202 to drive the sampling tube 204 to rise, and stops after the guide vertical rod 103 rises to the limit position. At the same time, since the arc pressure plate 118 has dropped a certain distance, the inclined surface block 211 follows the L-shaped plate frame 104 to rise to the top and is squeezed by the arc pressure plate 118 from the inside of the rectangular flat groove 107 and detached. After the L-shaped plate frame 104 is raised, the button 114 is pressed. After the button 114 is pressed, the first motor 131 is started to drive the second gear cylinder 133 to rotate. When the second gear cylinder 133 rotates, it uses the engagement with the tooth plate 126 to drive the return frame plate 121 to move right, so that the material receiving box 127 is located below the sampling tube 204. Then the cylinder 201 starts to push the circular frame 202 to descend. Since the inclined surface block 211 has been aligned with the rectangular flat The groove 107 is separated, so the sampling tube 204 will not be driven to descend again at this time, only the auger blade 207 will descend alone, and the descent of the side slide bar 209 will cause the sixth spring 215 to drive the transverse rod 108 to rotate again, so that the threaded tube 115 rotates and uses the threaded rod 116 to raise and reset the arc pressure plate 118, and the descent of the auger blade 207 will push the sample inside the sampling tube 204 to fall to the inner side of the receiving box 127. When a certain amount of sample falls on the top of the lifting plate 129, the lifting plate 129 will be pressed to descend and press the L-shaped pressure plate 130 at the same time. After being pressed, the L-shaped pressure plate 130 will drive the tooth plate 126 to descend, be pulled out from the inner side of the insertion port 124 and separate from the second gear cylinder 133. Since the return frame plate 121 is no longer limited by the second gear cylinder 133 at this time, it moves left and resets under the elastic force of the second spring 123, and the entire sampling process is completed at this time.
