Description

Technical Field

[0001] The invention relates to the technical field of soil layer rock drilling, in particular to an excavation device used for geological exploration. Background Art

[0002] Geological exploration is to go deep underground through mechanical tools or excavation to understand the underground geological conditions. Especially in areas with sparse surface outcrops, complex rock changes or complex geological structures, ground observation alone cannot fully understand the underground conditions. Therefore, geological exploration equipment is needed to obtain geological information and data deep underground. The application of this type of drilling equipment can effectively improve exploration efficiency and accuracy, and provide data support for further geological research and resource exploitation.

[0003] When the drill bit of geological exploration and excavation equipment encounters hard materials during the drilling process, the drill bit and the material will have a hard collision, causing huge friction and impact force. When these forces act on the surface of the drill bit, they quickly wear out the cutting edge on its surface, causing serious wear and abrasion on the surface of the drill bit, and even deformation or breakage. At the same time, the drill bit continues to rotate under the drive of the motor. The rotational force provided by the motor fails to effectively break through the hard material. The rotation of the drill bit cannot achieve efficient cutting. On the contrary, the concentrated force at the contact point of the drill bit aggravates the damage. The hard collision of the drill bit causes drilling to be obstructed. The continuous high-intensity impact and friction further increase the load on the drill bit, causing its cutting performance to decline rapidly and damage is inevitable. Summary of the invention

[0014] Compared with the prior art, the present invention provides an excavation device for geological exploration, which has the following beneficial effects: 1. The excavation equipment used for geological exploration is arranged by a connecting mechanism. When the drill bit encounters a hard material, the reaction force on the drill bit increases violently. At this time, the reaction force on the drill bit increases the mutual resistance between the limit block and the limit groove. The side of the limit block is an inclined surface. At this time, under the action of the increased interaction force, a part of the limit block compression spring is retracted into the inner wall of the connector. At this time, the limit block and the plug-in column rotate relative to each other, and the limit block rotates on the annular groove, thereby preventing the force of the drive motor from continuing to be transmitted to the drill bit. This design can effectively control the rotation of the drill bit when encountering a hard object, and avoids damage to the drill bit due to inability to withstand the reaction force when it is too large.

[0015] 2. The excavation equipment used for geological exploration utilizes a connection mechanism to connect the inner wall of the connector on the drill bit with the plug-in column. After the inclined surface on the limit block contacts the plug-in column, the limit groove on the plug-in column is engaged with the limit block under the action of a spring. When disassembly is required, the movable handle is pulled, and the movable handle drives the limit block, so that the limit block is no longer engaged with the limit groove, so that the drill bit can be quickly disassembled, which plays a role in quick connection and disassembly.

[0016] 3. The excavation equipment used for geological survey is set up with an energy-absorbing mechanism. When the drill bit encounters a hard material, the drill bit will vibrate under the action of a reaction force. The drill bit will be subjected to a reaction force, causing the drill bit to vibrate, driving the base to vibrate. The base drives the spring 2 to be stretched, which plays a buffering role, reduces the vibration of the body and the impact force on the drill bit, thereby improving the stability of the equipment and extending its service life.

[0017] 4. The excavation equipment used for geological exploration utilizes a guide mechanism. When the drill bit moves downward, the surface of the drill bit will resist the ball bearing. Under the action of spring three, the drill bit is stably moved vertically downward. The ball bearing reduces friction, preventing the drill bit from shifting or tilting during the drilling process, thereby ensuring the accuracy and efficiency of drilling.

[0023] 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.

[0024] 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.

[0025] The energy absorbing mechanism 6 includes a level 61 and a corner column 62. The level 61 is arranged on the inner wall of the base 1. The level 61 is used to detect whether the base 1 is in a horizontal state. In the excavation equipment for geological exploration, ensuring the level of the equipment is crucial to the accuracy and stability of the drilling operation. The level 61 can provide real-time inclination data to help the operator adjust the posture of the equipment to ensure the accuracy of the drilling process and avoid the deflection or instability of the drill bit 53 caused by the tilt of the equipment, thereby improving the working efficiency and accuracy. The side of the corner column 62 is fixedly connected with a bottom support column 63, and 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 to the bottom support column 63, so that the adjacent corner columns 62 are relatively fixed, so that the corner columns 62 form a sliding connection constraint relationship with the base 1, so that the base 1 can slide up and down stably, and the top of the corner column 62 is fixedly connected with a top limit plate 65, so that the highest position of the upward movement of the base 1 is limited, and the inner wall of the corner column 62 is threadedly connected with The second threaded rod 66 has a movable support block 67 rotatably connected to its bottom, and a spiral positioning rod 68 is fixedly connected to the bottom of the movable support block 67. Rotating the second threaded rod 66 drives the movable support block 67 to move downward, and the movable support block 67 drives the spiral positioning rod 68 to move downward and plug into the ground. When the movable support block 67 continues to move downward, the level of the base 1 can be adjusted by adjusting the length of contact between the movable support block 67 of different parts and the ground. The level meter 61 is used to observe whether the adjustment is in place. The outer wall of the movable support block 67 is slidably connected to the inner wall of the corner column 62, and one end of the 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 to the base 1. When the drill bit 53 drills into a hard part, the drill bit 53 will be subjected to 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, which plays a buffering role, reduces the vibration of the machine body and the impact force on the drill bit 53, thereby improving the stability of the equipment and extending its service life.

[0026] The guide mechanism 7 includes a hollow fixed block 71, which is fixedly connected to the top of the base 1. One end of a spring three 72 is fixedly connected to the inner wall of the hollow fixed block 71, and the other end of the spring three 72 is fixedly connected to a reciprocating block 73. The outer wall of the reciprocating block 73 is provided with a ball 74. The outer wall of the reciprocating block 73 is slidably connected to the inner wall of the hollow fixed block 71. The guide mechanism 7 is provided with three groups, and the three groups of guide mechanisms 7 are arranged in a circular array around the drill bit 53, so that under the action of the spring three 72, the reciprocating block 73 and the ball 74 evenly resist the outer wall of the drill bit 53, thereby improving the stability of the drill bit 53 and preventing the drill bit 53 from being offset or damaged due to uneven pressure.

[0027] In summary, when the excavation equipment for geological exploration is used, the inner wall of the connector 54 on the drill bit 53 is plugged into the plug-in column 55, and after the inclined surface on the limit block 511 contacts the plug-in column 55, the limit groove 57 on the plug-in column 55 is engaged with the limit block 511 under the action of the spring 1 510. 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 engaged with the limit groove 57, so that the drill bit 53 can be quickly disassembled, which plays the role of quick connection and disassembly.

[0028] The driving motor 51 is turned on to drive the active disk 52 to rotate, and the active disk 52 drives the plug-in column 55 to rotate. The limit groove 57 on the plug-in column 55 abuts against the limit block 511. The limit block 511 is tightly abutted against the limit groove 57 under the action of the spring 1 510, so that the limit block 511 drives the connector 54 and the drill bit 53 to rotate to perform drilling. When the drill bit 53 encounters a hard material, the reaction force on the drill bit 53 increases violently. At this time, the reaction force on the drill bit 53 causes the limit block 511 and the limit groove 57 to mutually abut against each other. The resistance force increases, and the side of the limit block 511 is an inclined surface. At this time, under the action of the increased interaction force, the limit block 511 compresses the spring 1 510 partly retracted into the inner wall of the connector 54. At this time, the limit block 511 rotates relative to the plug-in column 55 and slides in the annular groove 56, thereby preventing the force of the drive motor 51 from continuing to be transmitted to the drill bit 53. This design can effectively control the rotation of the drill bit 53 when encountering hard objects, and avoids the drill bit 53 from being damaged due to being unable to withstand the reaction force when it is too large. The rotation of the threaded rod 1 58 drives the inner connecting plate 59 to approach and move away from the limit block 511, so that the compression amount of the spring 1 510 between the limit block 511 and the inner connecting plate 59 is adjusted, which plays a role in adjusting the force of the spring 1 510 squeezing the limit block 511, and different settings are made for different drill bits 53.

[0029] When the drill bit 53 encounters a hard material, the drill bit 53 will vibrate under the action of a reaction force, and the drill bit 53 will be subjected to a reaction force, causing the drill bit 53 to vibrate, driving the base 1 to vibrate, and the base 1 drives the spring 2 69 to be stretched, which plays a buffering role, reducing the vibration of the body and the impact force on the drill bit 53, thereby improving the stability of the equipment and extending its service life.

[0030] When the drill bit 53 moves downward, the surface of the drill bit 53 will contact the ball 74. Under the action of the spring three 72, the drill bit 53 is stably moved vertically downward. The ball 74 reduces friction and prevents the drill bit 53 from deflecting or tilting during the drilling process, thereby ensuring the accuracy and efficiency of drilling.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
