[0002] When conducting geological exploration, it is necessary to obtain rocks and minerals at different depths and store them separately so that these samples can be tested and the parameters of the rocks and minerals at that depth can be obtained.

[0003] Because rock and minerals are relatively hard, it is inconvenient to excavate and sample them manually. Therefore, many mechanized sampling devices have appeared on the market. For example, a Chinese patent with a patent authorization announcement number of CN210422604U discloses an automatic deep rock sampling device for geological exploration, which includes a drilling barrel, a rotating shaft, a mounting barrel, a rotating motor and a mounting block. A drilling port is arranged at one end of the drilling barrel, a drilling thread is arranged on the outer side of the drilling barrel, a plurality of slurry outlet holes are arranged at the upper end of the drilling barrel, and the central position of the upper end of the drilling barrel is fixedly connected to the rotating shaft, etc. For example, a Chinese patent with a patent authorization announcement number of CN215296722U discloses a geological exploration sampling device, which includes a lifter, the lifter includes a first sleeve, a rotating gear assembly and a lifting rack assembly are installed inside the first sleeve, a drill bit is installed at the lower end of the lifter, and the drill bit rotates to drill underground when the lifter provides downward pressure, and the drill bit includes a spiral rod.

[0004] Whether it is the miniaturized sampling device provided by the above-mentioned patent or other types of miniaturized sampling devices, it is inconvenient for the drilling device to be lowered during the sampling process, because the hardness of the rock is relatively large, and the weight of the sampling device cannot meet the demand for the drilling device to be lowered.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 7 , Fig. 9As shown, a rock core sampling device for geological exploration includes a support frame 1, a motor 2, a transmission rod 4 and a drill 5. The support frame 1 includes a first disk 13, a vertical rod 11 and a threaded rod 12. A first through hole 18 is provided in the middle of the first disk 13. The diameter of the first through hole 18 is larger than the outer diameter of the drill 5. The vertical rod 11 is vertically fixed above the first disk 13. The lower end of the threaded rod 12 is inserted into the first disk 13 through a bearing connection, and the vertical rod 11 and the threaded rod 12 are located on the same diameter. In addition, a plurality of ear plates are provided on the first disk 13. After the location of the drilling sampling is determined, the drill bit carried is installed on the output shaft of the motor 2, and a plurality of holes are drilled on the surface of the rock and the mineral, and an expansion bolt is buried in each hole. After the expansion bolt is installed, the first disk 13 is placed on the rock and the mineral, and the ear plate is sleeved on the expansion bolt, and a nut is threadedly sleeved on the upper end of the expansion bolt. Under the action of the nut, the first disk 13 is stably placed relative to the rock and the mineral. After the first disk 13 is stably placed, heavy objects can be piled on it (when expansion bolts cannot be set, heavy objects can also be set to force the device to be stably placed), such as a battery that can be carried, and other ores can also be placed on the first disk 13. In short, the support frame 1 is stably placed, and the battery provides power for the operation of the motor 2. A horizontal plate 21 is arranged above the first disk 13, one end of the horizontal plate 21 is sleeved on the vertical rod 11, and the other end is threadedly sleeved on the threaded rod 12. Therefore, when the threaded rod 12 rotates, the horizontal plate 21 can be controlled to rise and fall, and the motor 2 is inverted, and the output shaft is connected through the horizontal plate 21 through a bearing, that is, the rise and fall of the horizontal plate 21 can control the rise and fall of the motor 2. After the cross plate 21 is stably installed on the support frame 1, the transmission rod 4 is installed on the output shaft of the motor 2, and then the drill 5 is installed at the lower end of the transmission rod 4. In order to facilitate the disassembly of the transmission rod 4, the motor 2 and the drill 5, a second polygonal column 22 is fixedly provided on the lower end of the transmission rod 4 and the output shaft of the motor 2, and a second polygonal groove 41 is provided on the upper end surface of the transmission rod 4 and the upper end surface of the top shaft of the drill 5. The second polygonal column 22 is connected by bolts and inserted into the second polygonal groove 41. Therefore, the motor 2 can drive the drill 5 to rotate at a high speed under operation. At the same time, the staff can rotate the threaded rod 12 to control the cross plate 21 to drive the motor 2, the transmission rod 4 and the drill 5 to descend, so as to drill holes in the rock. The explorers carry two types of drillers 5, one is set as a drill barrel structure (with a drainage hole 51 on the top), and the other is set as a spiral structure. The driller 5 with a spiral structure can continuously drill holes within the length of a transmission rod 4. The driller 5 with a drill barrel structure cannot continue to work after being filled with ore. Therefore, it can be used to obtain relatively complete ore.

[0029] Because it is necessary to drill ores at different depths for detection, multiple transmission rods 4 are provided. In order to facilitate changing the number of transmission rods 4 according to the drilling progress, the length of the transmission rod 4 is smaller than the length of the threaded rod 12 and the vertical rod 11. This arrangement avoids the disassembly and assembly of the transmission rod 4 due to its long length.

[0030] like Figure 3 As shown, in order to facilitate the staff to control the rotation of the threaded rod 12, a rotating wheel 17 is provided at the upper end of the threaded rod 12, and the staff can control the rotation of the threaded rod 12 by rotating the rotating wheel 17. In addition, in order to facilitate the disassembly of the cross plate 21 and the threaded rod 12, a first polygonal groove 15 is provided on the upper end surface of the threaded rod 12, and a first polygonal column 16 is provided in the middle of the rotating wheel 17. The first polygonal column 16 is connected by bolts and inserted into the first polygonal groove 15. When the motor 2 and the cross plate 21 need to be disassembled, the rotating wheel 17 can be removed from the upper end of the threaded rod 12 after rotating the bolts to release the restriction of the rotating wheel 17 and the threaded rod 12.

[0031] Example 2

[0032] like Figure 1 , Figure 2 , Figure 7 , Fig. 9As shown, a rock core sampling device for geological exploration includes a support frame 1, a motor 2, a transmission rod 4 and a drill 5. The support frame 1 includes a first disk 13, a vertical rod 11 and a threaded rod 12. A first through hole 18 is provided in the middle of the first disk 13. The diameter of the first through hole 18 is larger than the outer diameter of the drill 5. The vertical rod 11 is vertically fixed above the first disk 13. The lower end of the threaded rod 12 is inserted into the first disk 13 through a bearing connection, and the vertical rod 11 and the threaded rod 12 are located on the same diameter. In addition, a plurality of ear plates are provided on the first disk 13. After the location of the drilling sampling is determined, the drill bit carried is installed on the output shaft of the motor 2, and a plurality of holes are drilled on the surface of the rock and the mineral, and an expansion bolt is buried in each hole. After the expansion bolt is installed, the first disk 13 is placed on the rock and the mineral, and the ear plate is sleeved on the expansion bolt, and a nut is threadedly sleeved on the upper end of the expansion bolt. Under the action of the nut, the first disk 13 is stably placed relative to the rock and the mineral. After the first disk 13 is stably placed, heavy objects can be piled on it (when expansion bolts cannot be set, heavy objects can also be set to force the device to be stably placed), such as a battery that can be carried, and other ores can also be placed on the first disk 13. In short, the support frame 1 is stably placed, and the battery provides power for the operation of the motor 2. A horizontal plate 21 is arranged above the first disk 13, one end of the horizontal plate 21 is sleeved on the vertical rod 11, and the other end is threadedly sleeved on the threaded rod 12. Therefore, when the threaded rod 12 rotates, the horizontal plate 21 can be controlled to rise and fall, and the motor 2 is inverted, and the output shaft is connected through the horizontal plate 21 through a bearing, that is, the rise and fall of the horizontal plate 21 can control the rise and fall of the motor 2. After the cross plate 21 is stably installed on the support frame 1, the transmission rod 4 is installed on the output shaft of the motor 2, and then the drill 5 is installed at the lower end of the transmission rod 4. In order to facilitate the disassembly of the transmission rod 4, the motor 2 and the drill 5, a second polygonal column 22 is fixedly provided on the lower end of the transmission rod 4 and the output shaft of the motor 2, and a second polygonal groove 41 is provided on the upper end surface of the transmission rod 4 and the upper end surface of the top shaft of the drill 5. The second polygonal column 22 is connected by bolts and inserted into the second polygonal groove 41. Therefore, the motor 2 can drive the drill 5 to rotate at a high speed under operation. At the same time, the staff can rotate the threaded rod 12 to control the cross plate 21 to drive the motor 2, the transmission rod 4 and the drill 5 to descend, so as to drill holes in the rock. The explorers carry two types of drillers 5, one is set as a drill barrel structure (with a drainage hole 51 on the top), and the other is set as a spiral structure. The driller 5 with a spiral structure can continuously drill holes within the length of a transmission rod 4. The driller 5 with a drill barrel structure cannot continue to work after being filled with ore. Therefore, it can be used to obtain relatively complete ore.

[0033] Because it is necessary to drill ores at different depths for detection, multiple transmission rods 4 are provided. In order to facilitate changing the number of transmission rods 4 according to the drilling progress, the length of the transmission rod 4 is smaller than the length of the threaded rod 12 and the vertical rod 11. This arrangement avoids the disassembly and assembly of the transmission rod 4 due to its long length.

[0034] like Figure 3 As shown, in order to facilitate the staff to control the rotation of the threaded rod 12, a rotating wheel 17 is provided at the upper end of the threaded rod 12, and the staff can control the rotation of the threaded rod 12 by rotating the rotating wheel 17. In addition, in order to facilitate the disassembly of the cross plate 21 and the threaded rod 12, a first polygonal groove 15 is provided on the upper end surface of the threaded rod 12, and a first polygonal column 16 is provided in the middle of the rotating wheel 17. The first polygonal column 16 is connected by bolts and inserted into the first polygonal groove 15. When the motor 2 and the cross plate 21 need to be disassembled, the rotating wheel 17 can be removed from the upper end of the threaded rod 12 after rotating the bolts to release the restriction of the rotating wheel 17 and the threaded rod 12.

[0035] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, in order to facilitate the staff to carry the device, it also includes a second disk body 3, a threaded hole 33 is set on the second disk body 3, and a plurality of second slots 34 are set on the lower side, and a plurality of first slots 14 are set on the upper side of the first disk body 13. When the device is stored, one end of the multi-transmission rod 4 can be inserted into the first slot 14, and the plurality of transmission rods 4 are evenly distributed along the circumference of the disk body, and then the motor 2 is installed on the second disk body 3 by bolts, and the drill 5 is installed on the output shaft of the motor 2. Finally, the other end of the plurality of transmission rods 4 is inserted into the second slot 34, and the threaded rod 12 is controlled to rotate through the threaded hole 33. This arrangement can store multiple devices of the device in the space formed by the first disk body 13 and the second disk body 3, which provides convenience for the staff to move and occupies a smaller transportation space.

[0036] like Figure 4 , Figure 5 As shown, when the support frame 1 is stably installed on the surface of the rock and mineral, the second disk body 3 can also be placed below the first disk body 13. Specifically, the second disk body 3 is provided with a second through hole 31 and a limiting hole 32. The second through hole 31 is located in the middle of the second disk body 3, and multiple limiting holes 32 are evenly distributed on the edge of the second disk body 3.
