Description

Technical Field

[0001] The present invention relates to the technical field of soil and rock drilling, and particularly to an excavation device for geological exploration. Background Art

[0002] Geological exploration is to penetrate deep underground through mechanical tools or excavation operations to understand the underground geological conditions. Especially in areas with scarce surface outcrops, complex lithological changes or complex geological structures, it is impossible to comprehensively understand the underground situation solely by ground observation. Therefore, it is necessary to rely on geological exploration equipment to obtain geological information and data in the deep underground. The application of such drilling equipment can effectively improve the exploration efficiency and accuracy, and provide data support for further geological research and resource exploitation.

[0003] When the drill bit of a geological exploration excavation device encounters hard substances during drilling, the drill bit makes a hard contact with the substances, resulting in huge frictional and impact forces. When these forces act on the surface of the drill bit, they quickly wear the cutting edges on its surface, leading to serious wear and abrasion on the surface of the drill bit, and even deformation or fracture may occur. At the same time, the drill bit continues to rotate driven by the motor, and the rotational force provided by the motor fails to effectively break through the hard substances. The rotational movement of the drill bit cannot achieve efficient cutting, but instead exacerbates the damage at the contact point of the drill bit due to the concentrated action of the forces. The hard collision of the drill bit causes the drilling to be blocked, and the continuous high-intensity impact and friction further increase the load of the drill bit, resulting in a rapid decline in its cutting performance, and damage is inevitable. Summary of the Invention

[0014] Compared with the prior art, the present invention provides a digging device for geological exploration, having the following beneficial effects:

[0015] 1. For the digging device for geological exploration, by using the connection mechanism, when the drill bit encounters a hard substance, the reaction force received by the drill bit increases violently. At this time, the reaction force received by the drill bit increases the mutual contact force between the limit block and the limit groove. The side surface of the limit block is an inclined surface. At this time, under the action of the increased mutual acting force, the limit block compresses the spring and part of it retracts into the inner wall of the connection head. At this time, the limit block rotates relative to the insertion column, and the limit block rotates on the annular groove, thereby preventing the force of the driving motor from being continuously transmitted to the drill bit. This design can effectively control the rotation of the drill bit when encountering hard objects, and avoid damage to the drill bit due to its inability to withstand excessive reaction force.

[0016] 2. For the digging device for geological exploration, by using the connection mechanism, the inner wall of the connection head on the drill bit is inserted into the insertion column. After the inclined surface on the limit block abuts against the insertion column, under the action of the first spring, the limit groove on the insertion column is clamped with the limit block. When disassembly is required, pull the movable handle, and the movable handle drives the limit block, so that the limit block is no longer clamped with the limit groove, and the drill bit can be quickly disassembled, playing a role in quick connection and disassembly.

[0017] 3. For the digging device for geological exploration, by using the energy absorption mechanism, when the drill bit encounters a hard substance, the drill bit will vibrate under the action of the reaction force. The drill bit will receive a reaction force, causing the drill bit to vibrate, driving the base to vibrate, and the base drives the second spring to be stretched, playing a buffering role, reducing the vibration of the machine body and the impact force received by the drill bit, thereby improving the stability of the equipment and extending its service life.

[0018] 4. For the digging device for geological exploration, by using the guiding mechanism, when the drill bit moves downward, the surface of the drill bit will abut against the rolling balls. Under the action of the third spring, the drill bit moves stably vertically downward. The rolling balls play a role in reducing friction, avoiding deviation or inclination of the drill bit during drilling, and ensuring the accuracy and efficiency of drilling.

Detailed implementation manner

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1 - Figure 10, a mining device for geological exploration, comprising: a base 1, a drill bit 53 for drilling into underground rock formations during geological exploration; a vertical support base 2 disposed on the top of the base 1, the vertical support base 2 being used to support and stabilize the vertical structure of the device, ensuring the stability of the entire device during operation; a manual lifting mechanism 3 disposed on the outer wall of the vertical support base 2, the manual lifting mechanism 3 being used to manually lift the drill bit 53 upward, mainly to provide a way to manually adjust the vertical height of the drill bit 53, facilitating the adjustment of the drilling depth as needed.

[0032] The manual lifting mechanism 3 includes a fixed platform 31 slidably connected to the outer wall of the vertical support base 2. A bottom driving wheel 32 is rotatably connected to the inner wall of the vertical support base 2, and a top driving wheel 33 is rotatably connected to the inner wall of the vertical support base 2. The top driving wheel 33 and the bottom driving wheel 32 are connected by a chain 34. The chain 34 is fixedly connected to the outer wall of the fixed platform 31. The shaft of the top driving wheel 33 is fixedly connected to a large turntable 35. When the large turntable 35 is rotated, the large turntable 35 drives the top driving wheel 33 to rotate. The top driving wheel 33 drives the chain 34, and the chain 34 drives the fixed platform 31 to move up and down, so as to achieve the manual lifting of the drill bit 53, facilitating the operator to adjust the height of the device as needed for drilling operations. The design of this structure can ensure the smoothness and stability of the manual lifting process and can conveniently adjust the position of the drill bit 53 according to the exploration needs.

[0033] The electric lifting mechanism 4 includes a winding roller 41, which is rotatably connected to the top of the base 1. A stepper motor 42 is fixedly connected to the top of the base 1. The output shaft of the stepper motor 42 is connected to the shaft of the winding roller 41 through a driving belt 43. One end of a pull rope 44 is fixedly connected to the winding roller 41, and the other end of the pull rope 44 is fixedly connected to a hook 45. The pull rope 44 passes through the top of the vertical support seat 2, and the stepper motor 42 is turned on. The stepper motor 42 drives the winding roller 41 to rotate through the driving belt 43. The winding roller 41 drives the pull rope 44, and the pull rope 44 drives the hook 45 to move up and down. The hook 45 is fixed to the top of the driving motor 51, so that the driving motor 51 can move up and down stably.

[0034] The connecting mechanism 5 includes a driving motor 51, which is fixedly connected to the top of the fixed platform 31. The output shaft of the driving motor 51 is fixedly connected to the active disk 52. The top of the drill bit 53 is fixedly connected to the connecting head 54. The bottom of the active disk 52 is fixedly connected to the plug-in column 55. The outer wall of the plug-in column 55 is provided with an annular groove 56. The outer wall of the plug-in column 55 is provided with a limiting groove 57. The inner wall of the connecting head 54 is threadedly connected to a threaded rod 58. The outer wall of the threaded rod 58 is rotatably connected to an inner connecting plate 59. The outer wall of the inner connecting plate 59 is fixedly connected to one end of a spring 510. The other end of the spring 510 is fixedly connected to a limiting block 511. The outer wall of the limiting block 511 is fixedly connected to a movable handle 512. The movable handle 512 It is slidably connected to the inner connecting plate 59, and the movable handle 512 is slidably connected to the connecting head 54. Pulling the movable handle 512 causes the limit block 511 to move toward the direction of the inner connecting plate 59, so that the limit block 511 no longer engages with the limit groove 57, thereby achieving a quick disassembly effect. The inner connecting plate 59 is slidably connected to the inner wall of the connecting head 54, and the top of the limit block 511 is provided with an inclined surface. When the plug-in column 55 is inserted into the connecting head 54, the plug-in column 55 contacts the inclined surface of the limit block 511, so that the limit block 511 squeezes the spring 1 510, so that after the limit block 511 is retracted into the connecting head 54, it engages with the limit groove 57 under the action of the spring 1 510, thereby achieving a quick engagement effect. The outer wall of the limit block 511 is slidably connected to the inner wall of the connecting head 54.

[0035] The energy absorption mechanism 6 includes a spirit level 61 and corner columns 62. The spirit level 61 is arranged on the inner wall of the base 1. The spirit level 61 is used to detect whether the base 1 is in a horizontal state. In the excavation equipment for geological exploration, ensuring the horizontality of the equipment is crucial for the accuracy and stability of the drilling operation. The spirit level 61 can provide real-time inclination data to help the operator adjust the posture of the equipment to ensure the accuracy during the drilling process and avoid the deviation or instability of the drill bit 53 caused by the inclination of the equipment, thereby improving the operation efficiency and accuracy. The side of the corner column 62 is fixedly connected with a bottom support column 63. The outer wall of the bottom support column 63 is fixedly connected with an intermediate connecting plate 64. Both sides of the intermediate connecting plate 64 are fixedly connected with the bottom support column 63, so that adjacent corner columns 62 are relatively fixed, forming a sliding connection constraint relationship between the corner columns 62 and the base 1, enabling the base 1 to slide up and down stably. The top of the corner column 62 is fixedly connected with a top limiting plate 65, restricting the highest position of the upward movement of the base 1. A second threaded rod 66 is threadedly connected to the inner wall of the corner column 62. The bottom of the second threaded rod 66 is rotatably connected with a movable support block 67. The bottom of the movable support block 67 is fixedly connected with a spiral positioning rod 68. Rotating the second threaded rod 66 drives the movable support block 67 to move downward. The movable support block 67 drives the spiral positioning rod 68 to move downward and insert into the ground. When the movable support block 67 continues to move downward, the horizontality of the base 1 can be adjusted by the different lengths of the contact between different parts of the movable support block 67 and the ground. Observe whether the adjustment is in place through the spirit level 61. The outer wall of the movable support block 67 is slidably connected with the inner wall of the corner column 62. One end of a second spring 69 is fixedly connected to the inner wall of the bottom support column 63, and the other end of the second spring 69 is fixedly connected with the base 1. When the drill bit 53 drills into a hard part, the drill bit 53 will receive a reaction force, causing the drill bit 53 to vibrate, driving the base 1 to vibrate. The base 1 drives the second spring 69 to be stretched, playing a buffering role, reducing the vibration of the machine body and the impact force received by the drill bit 53, thereby improving the stability of the equipment and extending its service life.

[0036] The guiding mechanism 7 includes a hollow fixed block 71. The hollow fixed block 71 is fixedly connected to the top of the base 1. One end of a third spring 72 is fixedly connected to the inner wall of the hollow fixed block 71, and the other end of the third spring 72 is fixedly connected with a reciprocating block 73. A ball 74 is arranged on the outer wall of the reciprocating block 73. The outer wall of the reciprocating block 73 is slidably connected with the inner wall of the hollow fixed block 71. Three groups of guiding mechanisms 7 are arranged in a circular array around the drill bit 53, so that under the action of the third spring 72, the reciprocating block 73 and the balls 74 uniformly contact the outer wall of the drill bit 53, improving the stability of the drill bit 53 and preventing the drill bit 53 from deviating or being damaged due to uneven pressure.

[0037] In summary, when the excavation equipment for geological exploration is in use, the inner wall of the connector 54 on the drill bit 53 is inserted into the insertion column 55. After the inclined surface on the limit block 511 abuts against the insertion column 55, under the action of the first spring 510, the limit groove 57 on the insertion column 55 is clamped with the limit block 511. When disassembly is required, the movable handle 512 is pulled, and the movable handle 512 drives the limit block 511, so that the limit block 511 is no longer clamped with the limit groove 57, and the drill bit 53 can be quickly disassembled, playing a role in quick connection and disassembly.

[0038] The driving motor 51 is started to drive the driving disc 52 to rotate. The driving disc 52 drives the insertion column 55 to rotate. The limit groove 57 on the insertion column 55 abuts against the limit block 511. The limit block 511 tightly abuts against the limit groove 57 under the action of the first spring 510, so that the limit block 511 drives the connector 54 and the drill bit 53 to rotate for drilling. When the drill bit 53 encounters a hard substance, the reaction force received by the drill bit 53 increases violently. At this time, the reaction force received by the drill bit 53 causes the mutual abutting force between the limit block 511 and the limit groove 57 to increase. The side surface of the limit block 511 is an inclined surface. At this time, under the action of the increased mutual acting force, the limit block 511 compresses the first spring 510 and partially retracts into the inner wall of the connector 54. At this time, the limit block 511 rotates relative to the insertion column 55 and slides in the annular groove 56, thereby preventing the force of the driving motor 51 from being continuously transmitted to the drill bit 53. This design can effectively control the rotation of the drill bit 53 when encountering hard objects, and avoid damage to the drill bit 53 due to its inability to bear when the reaction force is too large. Rotating the first threaded rod 58 drives the inner connecting plate 59 to approach and move away from the limit block 511, so that the compression amount of the first spring 510 between the limit block 511 and the inner connecting plate 59 is adjusted, playing a role in adjusting the magnitude of the force exerted by the first spring 510 to squeeze the limit block 511, and setting for different drill bits 53 under different conditions.

[0039] When the drill bit 53 encounters a hard substance, the drill bit 53 will vibrate under the action of the reaction force. The drill bit 53 will receive a reaction force, causing the drill bit 53 to vibrate, driving the base 1 to vibrate, and the base 1 drives the second spring 69 to be stretched, playing a buffering role, reducing the vibration of the machine body and the impact force received by the drill bit 53, thereby improving the stability of the equipment and extending the service life.

[0040] When the drill bit 53 moves downward, the surface of the drill bit 53 will abut against the ball 74. Under the action of the third spring 72, the drill bit 53 is stably perpendicular downward. The ball 74 plays a role in reducing friction, avoiding deviation or inclination of the drill bit 53 during drilling, and ensuring the accuracy and efficiency of drilling.
