Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and particularly relates to a sampling drill for geological exploration. Background Art

[0002] Geological exploration is an industry specialized in geophysical exploration, geological survey, mineral resource exploration, groundwater exploration, etc. The main purpose is to reveal the underground geological structure, mineral distribution, and groundwater resources, providing basic geological data and scientific basis for resource development and environmental protection. A sampling drill is an essential mechanical equipment in geological exploration, which is used to insert a sampling pipe deep into the ground to achieve sampling of geological layers at a certain depth.

[0003] The currently used sampling pipe is composed of an outer sampling pipe and an inner sampling pipe. The outer sampling pipe is sleeved outside the inner sampling pipe and is used to enter the ground under impact force, while the inner sampling pipe is used for storing geological samples. In order to increase the sampling depth, external threads and internal threads are respectively provided at the upper and lower ends of the sampling pipe for connecting and extending the sampling pipes. Currently, after the sampling pipe is impacted into the ground by the sampling drill, it is necessary for workers to erect the inner sampling pipe and the outer sampling pipe and then connect them through threads. Due to the large weight of the sampling pipe, it requires multiple people to sleeve the inner sampling pipe and the outer sampling pipe together, then erect them and align the threads for rotational connection, which is laborious and has low efficiency. Therefore, a sampling drill for geological exploration is needed to solve the above problems. Summary of the Invention

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] Please refer to Figures 1-7 , the present invention provides the following technical solutions:

[0026] A sampling drill for geological exploration, comprising a machine body 1, crawler traveling mechanisms 2 installed on the left and right sides of the machine body 1, and a lifting carriage 3 hinged to the front side of the machine body 1. A hydraulic cylinder 4 for driving the rotation of the lifting carriage 3 is installed on the machine body 1. The hydraulic cylinder 4 can rotate the lifting carriage 3 to a vertical state for facilitating geological sampling. A hydraulic vibratory hammer 5 is installed on the lifting carriage 3 for hammering a sampling pipe to make the sampling pipe enter the geology. A storage component 6 is installed on the side wall of the lifting carriage 3, and the storage component 6 is used for quickly storing and removing a sampling outer pipe 8 and a sampling inner pipe 9.

[0027] The storage component 6 includes mounting frames 61 installed on the upper and lower sides of the lifting carriage 3, a rotating shaft 62 rotatably connected between the two mounting frames 61, and end baffles 63 installed on the upper and lower sides of the rotating shaft 62. A support plate 64 is installed on the lower side of the rotating shaft 62. A plurality of "U"-shaped grooves are formed in the support plate 64. The support plate 64 is used for supporting the bottom of the sampling outer pipe 8, so that the sampling inner pipe 9 extends to the outside of the lower end of the sampling outer pipe 8. A first motor 65 for driving the rotation of the rotating shaft 62 is installed on the mounting frame 61. The rotation of the rotating shaft 62 can switch the positions of the sampling pipes on the storage component 6.

[0028] A clamping control mechanism 66 for quickly fixing and removing the sampling pipe is installed in the middle of the rotating shaft 62; the clamping control mechanism 66 includes a housing 661 installed on the rotating shaft 62, a plurality of fixed claws 662 installed in the housing 661, and a telescopic rod 663 slidably connected in the housing 661. The rotating end of the fixed claw 662 is connected with an incomplete gear 664. A rack 665 meshing with the incomplete gear 664 is installed on the telescopic rod 663. The telescopic movement of the telescopic rod 663 can drive the fixed claws 662 on both sides thereof to rotate to achieve clamping or loosening; a control frame 666 is vertically slidably connected in the housing 661. A limiting protrusion is arranged at the upper end of the control frame 666. A groove corresponding to the protrusion is arranged on the telescopic rod 663. The cooperation between the limiting protrusion and the groove can position the telescopic rod 663, so that the fixed claws 662 keep clamping the sampling outer pipe 8. A control block 667 is arranged at the bottom of the control frame 666. A driving inclined surface is arranged on the control block 667. When an electric claw 762 contacts and presses the driving inclined surface, the control frame 666 can slide upward to release the positioning state of the telescopic rod 663, so that the sampling pipe is convenient to remove.

[0029] Another side wall of the lifting carriage 3 is provided with a pipe fitting continuation assembly 7. The pipe fitting continuation assembly 7 is used to remove the sampling outer pipe 8 and the sampling inner pipe 9 from the storage assembly 6, and extend the lower end of the sampling inner pipe 9 out of the sampling outer pipe 8, and then automatically continue the connection of the sampling outer pipe 8 and the sampling inner pipe 9 to reach the corresponding sampling depth. The pipe fitting continuation assembly 7 includes a linear slide 71 installed on the side bracket of the lifting carriage 3, a mounting plate 72 installed at the output end of the linear slide 71 through a bracket, and support rings 73 installed at the upper and lower ends of the mounting plate 72. A rotary frame 74 is rotatably connected inside the support ring 73. The rotary frame 74 is a cylindrical structure with an opening on the side. A rotary drive mechanism 75 for driving the rotary frame 74 to rotate is installed on the mounting plate 72. The rotary drive mechanism 75 includes a toothed ring 751 key-connected to the rotary frame 74, a second motor 752 installed on the mounting plate 72, and a driving gear 753 installed at the output end of the second motor 752. The driving gear 753 meshes with the toothed ring 751 to drive the rotary frame 74 to rotate, so as to drive the rotation of the sampling pipe.

[0030] Two sets of continuation clamping mechanisms 76 are installed inside the rotary frame 74. The two sets of continuation clamping mechanisms 76 are distributed up and down inside the rotary frame 74. The continuation clamping mechanism 76 on the lower side inside the rotary frame 74 is used to clamp the sampling inner pipe 9, and the continuation clamping mechanism 76 on the upper side inside the rotary frame 74 is used to clamp the sampling outer pipe 8; the continuation clamping mechanism 76 includes a connecting rod 761 vertically installed on the inner wall of the rotary frame 74 and an electric claw 762 slidably connected to the connecting rod 761. A return spring 763 for driving the electric claw 762 to move upward for reset is installed on the connecting rod 761; the vertically movable setting of the continuation clamping mechanism 76 can enable the sampling pipe to move downward when threadedly connected, so that the sampling pipe can be smoothly threadedly connected.

[0031] The working process of the present invention is as follows:

[0032] When geological exploration sampling is required, first place the sampling pipe into the storage assembly 6, place the sampling inner pipe 9 into the sampling outer pipe 8, so that the bottom of the sampling outer pipe 8 is located on the support plate 64, and the bottom of the sampling inner pipe 9 is located on the end baffle 63 below the rotating shaft 62. Push the sampling outer pipe 8 towards the clamping control mechanism 66, so that the sampling outer pipe 8 squeezes the telescopic rod 663. The telescopic rod 663 drives the fixed claw 662 to rotate through the rack 665 and the incomplete gear 664, realizes the clamping of the sampling outer pipe 8, and enables the control frame 666 to position the telescopic rod 663, thereby completing the storage of the sampling pipe.

[0033] Drive the sampling drill rig to the sampling location. The hydraulic cylinder 4 drives the lifting carriage 3 to rotate to the sampling state. The linear slide 71 drives the mounting plate 72 to move towards the storage assembly 6, and makes the connecting clamping mechanism 76 on the upper side of the rotating frame 74 contact and press against the inclined surface of the control block 667. The control frame 666 moves upward, causing the fixed claw 662 to release the sampling outer tube 8. The connecting clamping mechanisms 76 on the upper and lower sides inside the rotating frame 74 respectively clamp the sampling outer tube 8 and the sampling inner tube 9, and move to directly below the hydraulic vibratory hammer 5. The hydraulic vibratory hammer 5 moves downward and contacts the top of the sampling tube. The connecting clamping mechanism 76 disengages. The hydraulic vibratory hammer 5 applies a downward force to the sampling tube, causing the sampling tube to enter the ground.

[0034] After the first section of the sampling tube enters the ground, the first motor 65 drives the rotating shaft 62 to rotate, causing the next sampling tube to enter the tube-taking position. The pipe fitting connection assembly 7 removes the sampling tube and moves it to the position directly below the hydraulic vibratory hammer 5. The electric claw 762 on the lower side inside the rotating frame 74 releases the sampling inner tube 9, allowing the sampling inner tube 9 to be threadedly connected to the sampling inner tube 9 that has already entered the ground under the action of gravity. The electric claw 762 clamps the sampling inner tube 9 again. The second motor 752 drives the rotating frame 74 to rotate, causing the sampling inner tube 9 to rotate for threaded connection. After the connection of the sampling inner tube 9 is completed, the electric claw 762 on the lower side inside the rotating frame 74 releases, and the electric claw 762 on the upper side also releases, allowing the sampling outer tube 8 to fall under the action of gravity and be threadedly connected to the sampling outer tube 8 below. The rotating frame 74 rotates again to achieve the threaded connection of the sampling outer tube 8. The hydraulic vibratory hammer 5 continues to impact. Repeating this operation can achieve sampling of deep geology.
