Driven by the hydraulic cylinder 1, the drill bit position is close to the ground, and at the same time, the motor body 2 and the adjusting device 5 are started again, so that the drill bit composed of the components starts to rotate at high speed, and the ground is drilled in an exploratory manner until the required hole size and depth are drilled. At this time, when the reamer is used for auxiliary work of geological exploration and sampling, the diameter of the hole expanded by the reamer can be better adjusted according to the actual use situation, so that the reamer can meet the different needs of users, expand the application range of the reamer, better sample relevant geological samples, and improve the work efficiency of geological exploration.

[0030] Reference Figures 1 to 8As shown, in this embodiment: the adjusting device 5 includes an assembly tube 51, which is rotatably connected to the surface of one side of the motor body 2, and the output end of the motor body 2 is fixedly connected to a hydraulic telescopic rod 52, and the output end of the hydraulic telescopic rod 52 is fixedly connected to a fixed head 53, and the end of the assembly tube 51 away from the motor body 2 is fixedly connected to an assembly frame 54, and one side of the assembly frame 54 is located at the inner wall position of the assembly tube 51 and is rotatably connected to a fixed frame 56, and the fixed head 53 is adapted to the inner wall size of the fixed frame 56, and one end of the fixed frame 56 is fixedly connected to a screw 55, and the surface of the assembly frame 54 is slidably connected to a slider 57, and the slider 57 is threadedly connected to the arc surface of the screw 55, and the two sides of the surface of the slider 57 are rotatably connected to adjusting rods 58, respectively, and the assembly frame 54 is Two rotating holes 59 are respectively provided on both sides of the surface, and the inner walls of the two rotating holes 59 are rotatably connected with rotating rods 510 respectively. One end of the rotating rod 510 and the adjusting rod 58 are respectively fixedly connected with mounting blocks 511, and the surface of the mounting block 511 is fixedly connected with a drill plate 512. The inner wall of the assembly tube 51 is fixedly connected with a fixing ring 514, and the inner wall of the fixing ring 514 is fixedly connected with a number of uniformly distributed anti-slip protrusions 513. Two fixing plates 515 are fixedly connected to the surface of the motor body 2, and the surfaces of the two fixing plates 515 are respectively provided with reinforcement holes 516 on the sides close to each other. Two first electric telescopic rods 517 are fixedly connected to the arc surface of the assembly tube 51, and the output ends of the two first electric telescopic rods 517 are respectively connected to the surfaces of the two fixing plates 515. When drilling a hole on the ground for geological exploration using a borehole reamer, firstly, the mounting frame 3 of the borehole reamer is installed at the ground position for geological sampling, and then the hydraulic telescopic rod 52 of the adjusting device 5 is started to extend the hydraulic telescopic rod 52 until the fixed head 53 fixedly connected on the output end of the hydraulic telescopic rod 52 is inserted into the inner wall of the fixed frame 56 at one end of the screw 55, and then the two first electric telescopic rods 517 on the surface of the assembly tube 51 are started to insert the ends of the first electric telescopic rods 517 into the reinforcing holes 516 on the fixing plate 515 on the motor body 2, and then the motor body 2 is started to rotate the hydraulic telescopic rod 52 on the output end, thereby rotating the screw 55, because the slider 57 is on the assembly frame 54. The slider 57 slides downward, causing the adjusting rod 58 on the slider 57 to rotate, thereby driving the two rotating rods 510 on both sides of the assembly frame 54 to rotate in the rotating holes 59 on the assembly frame 54. At this time, the arc plate 527 on the mounting block 511 rotates, thereby adjusting the distance between the two drill plates 512. After the distance adjustment is completed, the hydraulic telescopic rod 52 is retracted to insert the fixed head 53 into the inner wall of the fixing ring 514 on the inner wall of the assembly pipe 51. At the same time, the first electric telescopic rod 517 is started to disengage its output end from the reinforced hole 516 on the fixing plate 515. Then, the hydraulic cylinder 1 on the mounting frame 3 is started. Driven by the hydraulic cylinder 1, the drill position is brought close to the ground. At the same time, the motor body 2 is started again.The drill bit composed of the components starts to rotate at high speed, and performs exploration-style drilling on the ground until the required hole size and depth are reached. At this time, when the reamer is used for auxiliary work of geological exploration sampling, the diameter of the hole expanded by the reamer can be better adjusted according to the actual usage, so that the reamer can meet the different needs of users, expand the scope of application of the reamer, better sample relevant geological samples, and improve the work efficiency of geological exploration.

[0031] Reference Figures 1 to 8 As shown, in this embodiment: the output ends of the two first electric telescopic rods 517 are respectively fixedly connected with plug plates 523, and the size of the plug plates 523 is adapted to the inner wall of the reinforcement hole 516. Through the arrangement of the plug plates 523, when the output ends of the first electric telescopic rods 517 are inserted into the reinforcement hole 516 on the surface of the fixed plate 515, the plug plates 523 can be inserted into the reinforcement hole 516. At this time, the position of the assembly tube 51 will be more stable, and the hydraulic telescopic rod 52 can better drive the rotation of the screw rod 55 to adjust the spacing between the two drill plates 512, so that the aperture adjustment of the drill position is more efficient, accurate and stable, and also improves The limiting effect formed by the combination of the fixed plate 515 and the first electric telescopic rod 517 is improved. The two sides of the surface of the drill plate 512 are fixedly connected with arc plates 527 respectively. The arc surface of the arc plate 527 is provided with a plurality of evenly distributed protrusions 528. Through the arrangement of the arc plates 527, when the drilling plate is in use, the arc plates 527 on both sides can be in contact with the ground. When the drill plate 512 is in contact with the ground material, the high-speed rotating protrusions 528 will rotate and rub against the ground soil. At this time, when exploring and drilling, the ground breaking and drilling effect can be better performed, and the use effect and practicality of the adjustment device 5 are further improved.

[0032] Reference Figures 1 to 8As shown, in this embodiment: a stabilizing ring 524 is fixedly connected to the circular arc surface of the assembly tube 51, a slide groove 522 is opened on the circular arc surface of the stabilizing ring 524, and a rotating ring 525 is rotatably connected to the inner wall of the slide groove 522, and two stabilizing plates 526 are fixedly connected to the circular arc surface of the rotating ring 525, and the two stabilizing plates 526 are respectively fixedly connected to the surface of the motor body 2. Through the arrangement of the stabilizing ring 524 and the stabilizing plates 526, when the motor body 2 drives the drilling component position of the adjustment device 5 to rotate, the rotating ring 525 fixedly connected to the stabilizing plate 526 can rotate on the inner wall of the slide groove 522 on the surface of the stabilizing ring 524 when the assembly tube 51 rotates, thereby making the position of the assembly tube 51 more stable and less prone to shaking, thereby ensuring the stability of the drilling component position of the arc plate 527, and better performing the drilling operation of geological exploration. The surface of the assembly frame 54 on both sides The second electric telescopic rod 519 is fixedly connected to the inner wall of the assembly groove 521, and the second gear 520 is fixedly connected to the output end of the second electric telescopic rod 519. The first gear 518 is fixedly connected to the arc surface of the screw 55. Through the arrangement of the second electric telescopic rod 519, the first gear 518 and the second gear 520, after the spacing adjustment of the two drill plates 512 is completed and the drill aperture is adjusted, the second electric telescopic rod 519 on the inner wall of the two assembly grooves 521 is started, so that the teeth of the second gear 520 on the output end of the second electric telescopic rod 519 are engaged with the first gear 518 on the screw 55. At this time, when the reamer is drilling, it is not easy for the screw 55 to rotate abnormally, resulting in abnormal changes in the spacing between the two arc plates 527, thereby ensuring the stable size of the drilling aperture and improving the practicality of the adjustment device 5.

[0033] Reference Figure 1 , Figure 2 and Fig. 9As shown, in this embodiment: the strengthening device 6 includes a servo motor 61, the servo motor 61 is fixedly connected to the inner wall of the assembly frame 54, the output end of the servo motor 61 is fixedly connected to a screw rod 62, the arc surface of the screw rod 62 is threadedly connected to a stabilizing rod 63, the cross-sections of the two sides of the stabilizing rod 63 are arc-shaped, the stabilizing rod 63 is slidably connected to the inner wall of the assembly frame 54, the two sides of the surface of the assembly frame 54 are respectively fixedly connected to a rotating shaft frame 64, the arc surface of the rotating shaft frame 64 is rotatably connected to a reinforcing plate 65, a stabilizing groove 66 is provided on the surface of the reinforcing plate 65 near the assembly frame 54, and the stabilizing rod 63 is engaged with the inner wall of the stabilizing groove 66. When the borehole diameter of the reamer is adjusted and the exploration drilling has not yet been carried out, the servo motor 61 inside the assembly frame 54 is first started, and the servo motor 61 will start to operate, thereby driving the screw rod 62 on the output end of the servo motor 61 to rotate, because the stabilizing The rod 63 is limited by the sliding of the assembly frame 54, so the stabilizing rod 63 will slide downward under the rotation of the screw rod 62, and in the sliding process, the two sides of the stabilizing rod 63 are in contact and squeezed with the reinforcing plates 65 on the two rotating shaft frames 64, so that the reinforcing plates 65 rotate on the arc gates of the rotating shaft frames 64 until the two ends of the stabilizing rod 63 are respectively engaged with the stabilizing grooves 66 on the surfaces of the two reinforcing plates 65. At this time, one end of the two reinforcing plates 65 will contact each other, and then the hydraulic cylinder 1 and the motor body 2 and other components are operated to perform the drilling for exploration. At this time, when the reamer is in use, it can better drill into the ground, reduce the resistance of the drill plate 512 on the adjusting device 5 when it contacts the ground, make the drilling more rapid and efficient, and also make the adjusting device 5 reduce the resistance, ensure the more normal use of the components, not prone to abnormal damage, and extend the service life of the adjusting device 5.

[0034] Reference Figure 1 , Figure 2 and Fig. 9 As shown, in the present embodiment: springs 67 are fixedly connected to both sides of the surface of the assembly frame 54, and the other end of the spring 67 is fixedly connected to the surface of the reinforcing plate 65. Through the setting of the spring 67, when the reamer is idle, the stabilizing rod 63 does not limit the position of the reinforcing plates 65. Under the action of the contraction force of the spring 67, the reinforcing plates 65 can rotate around the rotating shaft frame 64 as the axis, so that the two reinforcing plates 65 are attached to the surface of the assembly frame 54, which makes it difficult for the reinforcing plates 65 to shake or deviate, resulting in abnormal limit of the reinforcing plates 65 during use, thereby improving the actual operation and use requirements of the reinforcing device 6.

[0035] Reference Figure 1 , Figure 2 and Fig. 9As shown, in this embodiment: a bearing 69 is fixedly connected to the arc surface of the screw rod 62, the inner ring of the bearing 69 is fixedly connected to the screw rod 62, and the outer ring of the bearing 69 is fixedly connected to the inner wall of the assembly frame 54. Through the setting of the bearing 69, the servo motor 61 drives the screw rod 62 to rotate. When the position of the stabilizing rod 63 is adjusted, one end of the screw rod 62 can rotate with the assistance of the bearing 69, so that the screw rod 62 can better maintain stability during rotation, and is not prone to abnormal swinging, resulting in abnormalities of the stabilizing rod 63, thereby better reinforcing and limiting the position of the reinforcing plate 65.

[0036] Reference Figure 1 , Figure 2 and Fig. 9 As shown, in this embodiment: a protective sleeve 68 is sleeved on the arc surface of the screw rod 62, and the protective sleeve 68 is a rubber sleeve. The protective sleeve 68 is fixedly connected to the surface of the servo motor 61. Through the setting of the protective sleeve 68, when the reinforcing device 6 is in operation and the entire adjusting device 5 is deep below the ground, it will be covered by the soil produced by drilling. At this time, the protective sleeve 68 can effectively protect the output end position of the servo motor 61, so that the fine impurities such as soil impurities from the outside are not easy to enter the interior of the servo motor 61 along the gap at the output end of the servo motor 61, causing erosion and damage to the internal parts, thereby affecting the normal use of the servo motor 61, and also ensuring the normal use of the entire reinforcing device 6, and not prone to abnormalities.

[0037] Working principle: When using a borehole reamer to drill a hole on the ground for geological exploration, first, the mounting frame 3 of the borehole reamer is set up and installed at the ground location for geological sampling, and then the hydraulic telescopic rod 52 of the adjusting device 5 is started to extend the hydraulic telescopic rod 52 until the fixed head 53 fixedly connected to the output end of the hydraulic telescopic rod 52 is inserted into the inner wall of the fixed frame 56 at one end of the screw rod 55, and then the two first electric telescopic rods 517 on the surface of the assembly tube 51 are started to insert the ends of the first electric telescopic rods 517 into the reinforcement holes 516 on the fixing plate 515 on the motor body 2, and then the motor body 2 is started to rotate the hydraulic telescopic rod 52 on its output end. The slider 57 slides on the assembly frame 54, and the adjustment rod 58 on the slider 57 is rotated by sliding the slider 57 downward, thereby driving the two rotating rods 510 on both sides of the assembly frame 54 to rotate in the rotating holes 59 on the assembly frame 54. At this time, the arc plate 527 on the mounting block 511 rotates, so that the spacing between the two drill plates 512 is adjusted and changed. After the spacing adjustment is completed, the hydraulic telescopic rod 52 is retracted to insert the fixed head 53 into the inner wall of the fixing ring 514 on the inner wall of the assembly pipe 51, and the first electric telescopic rod 517 is started at the same time, so that the plug plate fixedly connected to the output end thereof is fixedly connected to the output end thereof. The second electric telescopic rod 519 on the inner wall of the two assembly grooves 521 is started at the same time, so that the teeth of the second gear 520 on the output end of the second electric telescopic rod 519 are engaged with the first gear 518 on the screw 55, and then the servo motor 61 inside the assembly frame 54 is started, and the servo motor 61 will start to run, thereby driving the screw 62 on the output end of the servo motor 61 to rotate. Because the stabilizing rod 63 will have a sliding limit effect on the assembly frame 54, the stabilizing rod 63 will slide downward under the rotation of the screw 62, and in the sliding process, the two sides of the stabilizing rod 63 are pressed against the two rotating The reinforcing plate 65 on the shaft frame 64 is in contact and squeezed, and then the hydraulic cylinder 1 on the mounting frame 3 is started. Driven by the hydraulic cylinder 1, the drill bit is positioned close to the ground, and the motor body 2 is started at the same time, so that the drill bit composed of the components begins to rotate at high speed, and the ground is drilled in an exploratory manner until the required hole size and depth are reached. At this time, when the reamer is used for auxiliary work in geological exploration and sampling, the diameter of the hole expanded by the reamer can be better adjusted according to actual usage, so that the reamer can meet the different needs of users, expand the scope of application of the reamer, better sample relevant geological samples, and improve the work efficiency of geological exploration.
