Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, and particularly relates to a sampling device for geological exploration. Background Technique

[0002] Geological exploration is a work of investigating and researching geological conditions such as rocks, stratigraphic structures, minerals, groundwater, landforms, etc. in a certain area. Through geological exploration, we can understand geological information such as underground resource distribution, geological structures, and seismic activities, provide guidance for resource development, provide guarantee for engineering construction, and provide a basis for environmental protection. When conducting geological exploration, it is necessary to obtain geological samples from underground, so a sampling device for geological exploration is required.

[0003] However, for the existing sampling device for geological exploration, the extension pipe used to connect the drill bit is generally fixed, which is difficult to increase the drilling depth of the drill bit and cannot well meet the drilling requirements under different geological conditions. Moreover, if the soil quality in the drilling area is relatively loose, it will be difficult for the drill bit to drive the extension pipe to rise by itself and break away from the drill hole. At this time, it is necessary for the staff to pull it out manually, which has a large labor intensity and is not convenient to operate.

[0004] To solve this technical problem, the utility model proposes a sampling device for geological exploration. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a sampling device for geological exploration, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A sampling device for geological exploration includes a drill bit, an extension pipe is arranged at the upper end of the drill bit, material taking channels are opened in both the drill bit and the extension pipe, material taking pipes are connected in both the drill bit and the extension pipe, track grooves are opened at the outer ends of the drill bit and the material taking pipes, a rotating ring is slidably connected to the outer end of the extension pipe, a track block is connected inside the rotating ring, a turbine is arranged at the outer end of the track block, fixing rings are rotatably connected to the upper and lower ends of the rotating ring, a support rod is connected to the side end of the fixing ring, a servo motor is connected to the side end of the support rod, a worm is connected to the driving end of the servo motor, connection grooves are opened at the upper ends of both the drill bit and the extension pipe, and a connecting plate is connected to the lower end of the extension pipe.

[0008] Preferably, a spiral blade is arranged at the outer end of the drill bit, the material taking channel penetrates through the drill bit and the extension pipe, and the material taking pipe is slidably connected in the material taking channel.

[0009] Preferably, the track block is slidably connected in the track groove, the worm is meshed with the turbine, a support frame is connected to the side end of the support rod, an anti-slip plate is arranged at the lower end of the support frame, anti-slip grooves are formed at the lower end of the anti-slip plate, and a control box is arranged at the upper end of the support rod.

[0010] Preferably, a baffle is connected to the lower ends of the drill bit and the extension pipe, the baffle is located in the material taking hole channel, and the length of the baffle in the material taking hole channel is the same as the pipe thickness of the material taking pipe.

[0011] Preferably, the connecting plate is slidably connected to the outer end of the connecting groove, threaded holes are formed in both the connecting plate and the connecting groove, and the two threaded holes are aligned and communicated, and can be connected by bolts.

[0012] Preferably, a clamping plate is arranged at the lower end of the support rod, anti-slip grooves are formed on the inner side of the clamping plate, and the clamping plate is located at the outer end of the extension pipe and can be connected to its outer surface.

[0013] Preferably, a first telescopic cylinder is connected inside the support rod, the driving end of the first telescopic cylinder is connected to a second telescopic cylinder at the lower end, the second telescopic cylinder is located at the lower end of the support rod, and the driving end of the second telescopic cylinder is connected to the side end of the clamping plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, by arranging a drill bit, an extension pipe and a rotating ring, starting the servo motor will drive the worm at the driving end to rotate. The rotation of the worm acts on the turbine, which will drive the rotating ring to rotate in the fixed ring. The rotation of the rotating ring will drive the extension pipe and the drill bit to rotate through the action of the track block and the track groove, so that the drill bit can drill into the ground and drive the extension pipe to move down. When the extension pipe is about to fall off from the rotating ring, another extension pipe can be connected to this extension pipe through the connecting groove and the connecting plate to extend the drilling depth of the drill bit. By connecting multiple extension pipes, the drilling depth of the drill bit can be continuously increased, and by combining multiple extension pipes into different lengths, the drilling requirements under different geological conditions can also be adapted. The device has a simple structure and is easy to operate, can adjust the drillable depth of the drill bit, and helps to improve the drilling efficiency.

[0016] In the utility model, by arranging a clamping plate, after the sampling is completed, reversing the servo motor can make the drill bit rotate in the reverse direction. If the soil quality in this area is good, the drill bit can directly push out the extension pipe. If the soil in this area is relatively loose, at this time, through the cooperation of the first telescopic cylinder, the second telescopic cylinder and the clamping plate, the extension pipe can be pulled out little by little, avoiding the situation that when the drill bit encounters loose terrain, it is difficult to take out and requires manual extraction by workers.

Specific embodiments

[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-5 shown, a sampling device for geological exploration includes a drill bit 1. A spiral blade is provided at the outer end of the drill bit 1, so that when the drill bit 1 rotates, it can drill into the ground like a screw relying on the thread blade. When the drill bit 1 rotates in reverse, it can provide a downward thrust through the interaction between the spiral blade and the soil. An extension pipe 2 is provided at the upper end of the drill bit 1. Material taking hole channels 3 are opened in both the drill bit 1 and the extension pipe 2. The material taking hole channels 3 penetrate the drill bit 1 and the extension pipe 2. Material taking pipes 4 are connected in both the drill bit 1 and the extension pipe 2. The material taking pipes 4 are slidably connected in the material taking hole channels 3.

[0025] A baffle 16 is connected to the lower ends of the drill bit 1 and the extension pipe 2. The baffle 16 is located in the material taking hole channel 3. The length of the baffle 16 in the material taking hole channel 3 is the same as the wall thickness of the material taking pipe 4. In this way, all the material taking pipes 4 will form a round hole channel, and there will be no blockage when the soil enters the material taking pipe 4. The baffle 16 can restrain the material taking pipe 4 so that it will not move due to the friction between the two when it contacts the soil. Track grooves 5 are opened at the outer ends of the drill bit 1 and the material taking pipe 4.

[0026] The outer end of the extension pipe 2 is slidably connected with a rotating ring 6. Inside the rotating ring 6, there is a track block 7 which is slidably connected inside the track groove 5. At the outer end of the track block 7, there is a turbine 8. The upper and lower ends of the rotating ring 6 are rotatably connected with a fixed ring 9 which is used to support and restrict the rotating ring 6 so that it can only rotate but not move. The side end of the fixed ring 9 is connected with a support rod 10 which is used to support and fix the fixed ring 9. The side end of the support rod 10 is connected with a support frame 15. At the lower end of the support frame 15, there is an anti-slip plate with anti-slip grooves opened at its lower end. The anti-slip plate contacts the ground and is used to ensure the stability of the device during operation. The side end of the support rod 10 is connected with a servo motor 11. The driving end of the servo motor 11 is connected with a worm 12 which meshes with the turbine 8. At the upper end of the support rod 10, there is a control box.

[0027] Start the servo motor 11, which will drive the worm 12 at its driving end to rotate. The rotation of the worm 12 acts on the turbine 8, enabling the turbine 8 to drive the rotating ring 6 to rotate inside the fixed ring 9. In this way, the rotating ring 6 will drive the extension pipe 2 inside it to rotate through the track block 7, so that the drill bit 1 can rotate.

[0028] Both the drill bit 1 and the upper end of the extension pipe 2 are provided with connection grooves 13. The lower end of the extension pipe 2 is connected with a connecting plate 14 which is slidably connected to the outer end of the connection groove 13. Threaded holes are opened in both the connecting plate 14 and the connection groove 13, and the two threaded holes are aligned and communicated, and can be connected by bolts.

[0029] As the drill bit 1 drills into the ground, the extension pipe 2 will also gradually drill into the ground. When the extension pipe 2 is about to break away from the rotating ring 6, an extension pipe 2 can be placed at its upper end. The two extension pipes 2 can be fixedly connected together through the connection groove 13, the connecting plate 14 and bolts, so as to extend the drilling depth of the drill bit 1.

[0030] At the lower end of the support rod 10, there is a clamping plate 17 which is located at the outer end of the extension pipe 2 and can be connected to its outer surface, so as to clamp and fix the extension pipe 2. Anti-slip grooves are opened on the inner side of the clamping plate 17, enabling the clamping plate 17 to clamp the extension pipe 2 more firmly. Inside the support rod 10, there is a first telescopic cylinder 18. The lower driving end of the first telescopic cylinder 18 is connected with a second telescopic cylinder 19 which is located at the lower end of the support rod 10. The driving end of the second telescopic cylinder 19 is connected with the side end of the clamping plate 17. When the drill bit 1 cannot lift the extension pipe 2 up by its own reverse rotation, at this time, stop the servo motor 11, start the first telescopic cylinder 18 to push the second telescopic cylinder 19 downward, and then start the second telescopic cylinder 19 to push the clamping plate 17, so that the clamping plate 17 clamps and fixes the extension pipe 2. Then retract the first telescopic cylinder 18, so as to drive the extension pipe 2 to rise through the first telescopic cylinder 18. By operating like this continuously, the extension pipe 2 can be gradually lifted out of the drill hole.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
