It can speed up the sampling work, greatly reduce the damage to vegetation and protect the environment. The backpack drill integrates all the necessary equipment in a backpack, which is convenient for one person to transport. It is very suitable for use in geological exploration, power exploration, traffic detection, arch lining sampling, geological disaster exploration and professional academic research.

[0003] After searching, the applicant found that a Chinese patent disclosed "a geological sampling backpack drilling rig", and its publication (announcement) number is "CN 115949342 B".

[0050] For details, please refer to the attached manual. Figure 3 The present application provides two core tubes 3, which are arranged in half. In this way, when any one of the core tubes 3 is severely corroded, it can be conveniently replaced. At this time, there is no need to replace the two core tubes 3 simultaneously, thereby reducing the loss of materials. At the same time, since both core tubes 3 can be replaced, the service life of the entire tube body is also extended.

[0051] Reference Manual Attached Figure 4 , by rotating the control bolt 6 inside the assembly groove 4 on one core tube 3, while rotating the control bolt 6, the gear ring 10 inside the transmission groove 9 drives the remaining retaining bolts 8 to rotate, so that when one end of the control bolt 6 is connected and fixed with the second assembly hole 11 on the other core tube 3 through the first assembly hole 5, the remaining retaining bolts 8 will also synchronously pass through the corresponding first assembly hole 5 and connect with the second assembly hole 11 on the other core tube 3. At this time, the two core tubes 3 can be conveniently fixed, and the entire connection process is simple, and only a single operation is required;

[0052] Reference Manual Attached Figure 4 When it is necessary to observe the materials drilled inside the two coring tubes 3, the two coring tubes 3 can be conveniently separated by simply rotating the control bolt 6 in the opposite direction according to the above-mentioned operation of fixing the two coring tubes 3. The whole operation process is simple and convenient.

[0053] Embodiment 2:

[0054] Reference Manual Attached Figure 5A thickening layer 13 is fixedly installed at the bottom of the outer sleeve 2, and a guide tube 14 is fixedly installed at the bottom of the two core tubes 3. The length of the guide tube 14 is equal to the length of the thickening layer 13. A heat insulation layer 15 is fixedly installed at one end of the top of the outer sleeve 2, and the inside of the heat insulation layer 15 is adapted to the outside of the retaining portion 12;

[0055] Reference Manual Attached Figure 5 The retaining portion 12 includes a gear groove 1201 formed on the outer wall of the core tube 3, and the outer sleeve 2 and the surface of the heat insulation layer 15 are provided with intersecting retaining holes 1202. A high temperature resistant motor 1203 is fixedly installed in the inner cavity of the heat insulation layer 15.

Figure 5 , 6 , when the two combined coring tubes 3 need to be placed in the inner cavity of the outer sleeve 2, it is only necessary to first insert the two combined coring tubes 3 into the inner cavity of the outer sleeve 2. Before insertion, the gear grooves 1201 on the two coring tubes 3 need to be aligned with the control gear 1205, and then the high temperature resistant motor 1203 inside the thermal insulation layer 15 is started. The high temperature resistant motor 1203 can use an asynchronous motor and must have an automatic locking function. At this time, the high temperature resistant motor 1203 can drive the control gear 1205 to rotate through the control rod 1204. In this way, when the control gear 1205 engages with the gear grooves 1201 on the two coring tubes 3, the two coring tubes 3 can be automatically driven to be introduced into the inner cavity of the outer sleeve 2. After the catheters 14 on the two outer sleeves 2 are externally inserted into the inner cavity of the thickening layer 13, as the thickening layer 13 blocks the two coring tubes 3, the high temperature resistant motor 1203 can be turned off, thereby realizing the convenient assembly of the two coring tubes 3 and the outer sleeve 2;

[0057] Reference Manual Attached Figure 6 The high temperature resistant motor 1203 can also drive in reverse, thereby driving the two core tubes 3 to be conveniently separated from the outer casing 2, and the entire disassembly and assembly process is simple, which further improves the user's efficiency in assembling the two core tubes 3 and the outer casing 2 before drilling and separating the two core tubes 3 and the outer casing 2 before drilling.
