[0002] In the procedures of geological exploration and engineering quality inspection, it is usually necessary to use coring to collect samples and tests, so as to collect geological information and engineering quality information. In the coring process, the most important tool is the coring drill, which is usually composed of a driving component and a drilling component, and plays a very important role in the coring operation.

[0003] However, during the sampling process of the existing coring drill, the drill body is in direct contact with the core, and the rotating drill body is likely to drive the core to rotate together. Since the elastic deformation performance of the rock and concrete texture is poor, it is easy to cause the core to break and damage the sample. In addition, after coring, the core in the drill body cannot be pushed out, which is inconvenient to collect the core. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a water-proof rock and soil coring drill comprises a shell 1, both sides of the shell 1 are fixedly connected with handles 2, the inner side of the shell 1 is fixedly connected with a motor 3, and both sides of the bottom of the shell 1 are fixedly connected with fixed blocks 4, the bottom of the shell 1 is provided with a coring mechanism 5, the coring mechanism 5 comprises a connecting block 6, the bottom top of the connecting block 6 is fixedly connected to the shell 1, and the bottom of the connecting block 6 is fixedly connected to an isolating tube 7, the bottom of the motor 3 is fixedly connected to a limit key 8, the outer side of the limit key 8 is fixedly connected to a spur gear 9, the outer side of the spur gear 9 is meshedly connected to three planetary gears 10, the tops of the three planetary gears 10 are rotatably connected to the connecting block 6, and the bottoms of the three planetary gears 10 are rotatably connected to the isolating tube 7, one side of the three planetary gears 10 are meshedly connected to a gear ring 11, the outer side of the gear ring 11 is fixedly connected to a drill body 12, the bottom of the drill body 12 is fixedly connected to a cutter head 13, and both sides of the gear ring 11 are meshedly connected with bolts 17.

[0023] In this embodiment, the top inner side of the isolation cylinder 7 is rotatably connected to bevel gear 14, the bottom of bevel gear 14 is meshedly connected to push plate 15, the outer side of push plate 15 is slidably connected to the inner side of the isolation cylinder 7, the top of bevel gear 14 is meshedly connected to bevel gear 2 16, and one end of bevel gear 2 16 is rotatably connected to one side of the isolation cylinder 7.

[0024] The push plate 15 can be driven to move up and down by the bevel gear 14, so as to push the bottom of the core out of the isolation tube 7, so as to facilitate the removal of the core. When sampling, the drilling tool penetrates the sample and a complete core sample can be obtained.

[0025] In this embodiment, a T-shaped protrusion is provided on the top of the bevel gear 14, and a cylindrical protrusion is provided on the bottom of the bevel gear 14, and a thread is provided on the outer side of the cylindrical protrusion.

[0026] The bevel gear 14 can be connected to the isolation cylinder 7 through the protrusion on the top, so that the bevel gear 14 will not fall off.

[0027] In this embodiment, a circular protrusion is provided on one side of the bevel gear 16 , and a hexagonal hole is provided on one side of the circular protrusion of the bevel gear 16 .

[0028] The bevel gear 2 16 is connected to the isolation cylinder 7 via a circular protrusion, so that the bevel gear 2 16 can only rotate in the original position.

[0029] In this embodiment, two slide grooves are formed on the inner wall of the isolating cylinder 7, and a circular protrusion is formed on the inner wall of one side of the isolating cylinder 7, and a through circular hole is formed at one end of the circular protrusion.

[0030] The isolation cylinder 7 limits the moving direction of the push plate 15 through the sliding groove and constrains the freedom of movement of the push plate 15.

[0031] In this embodiment, screw holes are formed on both sides of the gear ring 11 , and round holes are formed on both sides of the top of the drill body 12 .

[0032] One end of the two bolts 17 passes through the drill body 12 in sequence and is connected to the gear ring 11 , thereby fixing the drill body 12 .

[0033] In this embodiment, a circular protrusion is provided on the top of the push plate 15, and a screw hole is opened on the top of the circular protrusion.

[0034] When the bevel gear 14 rotates, the push plate 15 can be driven to move through the action of the thread, and the push plate 15 can move up and down along its own axis.

[0035] It should be noted that the utility model is a water-proof rock and soil coring drill, which can protect the rock core and reduce fracture when in use. The specific implementation method is to start the motor 3, and the motor 3 will drive the limit key 8 and the spur gear 9 to rotate together. When the spur gear 9 rotates, it will drive the three planetary gears 10 to rotate together through the meshing action between the gears. The planetary gear 10 is restricted by the connecting block 6 and the isolation cylinder 7, and can only rotate in the original position after being driven by the spur gear 9;

[0036] When the three planetary gears 10 rotate, the gear ring 11 will be driven to rotate together. When the gear ring 11 rotates, the two bolts 17 will be driven to rotate together. Since the drill body 12 is restricted by the bolts 17 and is fixed on the outside of the gear ring 11, the bolts 17 will transfer the force to the drill body 12 when it moves. When the drill body 12 rotates, it will drive the cutter head 13 at the bottom to rotate together.

[0037] By aligning the bottom of the cutter head 13 with the top of the sample and pressing downward, the cutter head 13 breaks the contact part with the sample. As the cutter head 13 extends into the sample, the drilled core will enter the interior of the isolation tube 7. Since the isolation tube 7 isolates the core from the drill body 12, the friction and impact on the core are reduced, thereby protecting the core from breaking and making the sampling more complete. When the cutter head 13 penetrates from the top of the sample to the bottom, a complete core will be obtained.

[0038] During the sampling process, mud and sand may enter between the outer wall of the core and the inner wall of the isolation tube 7, making it difficult to remove the core from the core drilling tool. The existing core drilling tool may cause the core to break by hitting the drill bit. At this time, the push plate 15 can assist in removing the core. The specific implementation method is to rotate the two bolts 17 to move the two bolts 17 away from the drill body 12 until they are in meshing contact with the gear ring 11, thereby releasing the fixation of the drill body 12.

[0039] At this time, the drill body 12 is moved toward the bottom, the drill body 12 is removed from the coring drill, and then the bevel gear 16 is rotated. The bevel gear 16 is limited by the isolation tube 7, so it can only rotate in the original position, and the bevel gear 14 is driven to rotate together with the rotation. When the bevel gear 14 rotates, the push plate 15 is driven to move along its own axis through the meshing action of the thread, and the moving direction of the push plate 15 can be controlled by rotating the bevel gear 16 in different directions.

[0040] The push plate 15 is controlled to move toward the bottom by the bevel gear 16. During the movement, the push plate 15 pushes the core to move to the outside of the isolation tube 7. When the bottom of the core moves out of the isolation tube 7, the staff can slowly take out the core to avoid the core from breaking. After the core is taken out, the bevel gear 16 is rotated in the opposite direction to reset the push plate 15, and the drill body 12 is cleaned and reinstalled on the outside of the gear ring 11 through the bolt 17, waiting for the next use;

[0041] By providing the coring mechanism 5, the core can be protected during the coring process to prevent the high-speed rotating drill body 12 from contacting and hitting the core and causing it to break, thereby keeping the core sample intact and facilitating the collection of complete sample information. By providing the push plate 15, the bottom of the core can be pushed out from the inside of the isolation tube 7, making it easier for the staff to take out the core and avoiding damage to the core caused by hitting and dropping the drill bit.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
