In order to solve the problem that the drill bit is prone to tilt when drilling the soil layer, resulting in the drilling position being prone to deviation, and the drilling equipment does not have a shock-absorbing buffer structure, the continuous vibration during the drilling process is likely to cause equipment damage, which is not conducive to people's use, the prior art application number is 202220577712.X The patent can be applied, including a box body, the inner wall of the box body is fixedly connected with a fixed plate, the interior of the box body is provided with a lifting mechanism, and the top of the lifting mechanism is installed with a first motor. Although it can improve or even completely solve the above-mentioned disadvantages, during the actual construction operation, since the overall work of the drill bit structure requires a large number of workpieces, including some with large mass, and the construction area is basically outdoors, the natural conditions are relatively harsh, and the ground is mostly uneven. The movement and displacement of the drilling drill bit requires multiple workers to apply force to move it, which is very troublesome and laborious. When it slips out of the hand, it will cause local damage to the drill bit and injuries to the workers. The practical performance needs to be strengthened. Summary of the invention

The movement and displacement of the drilling drill bit requires multiple workers to apply force to move it, which is very troublesome and laborious. When the drill bit slips out of the hands, it may cause local damage to the drill bit and injuries to the workers, and the practical performance needs to be improved.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drilling drill bit specially used for geotechnical exploration and drilling construction that is easy to move, comprising a machine body, a bottom plate is provided below the machine body, a plurality of damping telescopic rods are evenly fixedly connected to the upper surface of the bottom plate, the top ends of the damping telescopic rods are fixedly connected to the lower surface of the machine body, a compression spring is sleeved on the outer side of the damping telescopic rod, the upper and lower ends of the compression spring are respectively fixedly connected to the contact surface of the machine body and the bottom plate, and a convenient moving unit is provided on the front and rear surfaces and the left and right sides of the bottom plate;

[0011] Compared with the prior art, the utility model has the following beneficial effects: the portable special drilling drill bit for geotechnical exploration and drilling construction has the following advantages over the traditional technology:

[0012] Through the cooperation between the machine body, the base plate, the damping telescopic rod, the compression spring and the easy-to-move unit, the staff applies a lateral pushing force to the machine body, so that the rollers in contact with the ground can roll, which can reduce the force required for the movement of the machine body. When encountering a depression in the ground during the travel process, the rollers on the front side of the lower moving direction will sink into the depression in the ground. Maintaining the pushing force on the machine body can make the triangular bracket rotate around the round rod, and the rollers at the top can rotate downward and press against the road surface above the depression. At this moment, continuing to maintain the forward pushing force can make the rollers move out of the depression in the ground more easily, which can reduce the force required for the machine body to move on uneven road conditions and greatly reduce the frequency required to lift the machine body, so as to reduce the chance of local damage to the machine body and injury to staff.

[0013] Through the coordination among the machine body, base plate, damping telescopic rod, compression spring and convenient moving unit, the machine body is moved to a relatively flat ground before drilling operation. The staff applies force to rotate the threaded disk to move the screw rod and anchor rod downward. With the continuous rotation of the threaded disk, the anchor rod can be inserted into the ground to enhance the stability of the machine body during subsequent operation. During the operation of inserting the anchor rod into the ground, there is no need for the staff to knock the top of the anchor rod with a hammer, which can avoid strong vibration of the machine body and facilitate the subsequent proper operation and use of the volume.

The front and rear surfaces of the bottom plate 2 are provided with convenient moving units 5 on the left and right sides, and the convenient moving units 5 include a support plate 501, a cavity block 502, a round rod 503, a triangular bracket 504, a roller 505, a vertical cylinder 506, a threaded disk 507, a screw rod 508, an anchor rod 509, a slide groove 510 and a slider 511. Multiple support plates 501 are fixedly connected to the left and right sides of the front and rear surfaces of the bottom plate 2, the lower surface of the support plate 501 is fixedly connected to the cavity block 502, the front surface of the cavity block 502 is fixedly connected to the round rod 503, the front side of the outer wall of the round rod 503 is rotatably connected to the triangular bracket 504, and the round rod 503 is connected to the bottom plate 2 through a dustproof bearing. The triangular bracket 504 is rotatably connected, so that the triangular bracket 504 can rotate around the round rod 503 as the center. A roller 505 is provided at each convex corner of the triangular bracket 504. The roller 505 is rotatably connected to the triangular bracket 504 through a pin rod, and the roller 505 can roll. The upper surface of the support plate 501 is rotatably connected to a vertical cylinder 506, and the vertical cylinder 506 is rotatably connected to the support plate 501 through a dustproof bearing. The top of the vertical cylinder 506 is fixedly connected to a threaded disk 507, and the inner wall of the threaded disk 507 is threadedly connected to a screw rod 508. The bottom end of the screw rod 508 is fixedly connected to an anchor rod 509. The outer wall of the anchor rod 509 is vertically provided with a slide groove 510 on both sides. The interior of the slide groove 510 is slidably clamped with a slider 511, and the slider 511 can slide inside the slide groove 510. The bottom plate 2 can slide up and down, but cannot move left and right, front and back, which can improve the stability of the anchor rod 509 when it moves up and down.

[0023] The drilling drill bit is easy to move for geotechnical exploration and drilling construction. During use, the staff applies a lateral pushing force to the body 1, so that the roller 505 in contact with the ground can roll, which can reduce the force required for the movement of the body 1. When encountering a depression in the ground during the movement, the roller 505 on the front side of the lower moving direction will sink into the depression in the ground. Maintaining the pushing force on the body 1 can make the triangular bracket 504 rotate around the round rod 503, so that the top roller 505 can rotate downward and press against the road surface above the depression. At this moment, continuing to maintain the forward pushing force can make the roller 505 move out of the depression in the ground more easily, which can reduce the force required for the body 1 to move on uneven road conditions. After the machine body 1 is moved to a relatively flat ground, the thrust required for moving the machine body 1 is stopped. Before drilling, the staff applies force to rotate the threaded disk 507. Due to the threaded connection between the threaded disk 507 and the screw rod 508, and the sliding limit of the slider 511 on the slide groove 510, the screw rod 508 and the anchor rod 509 can move downward. With the continuous rotation of the threaded disk 507, the anchor rod 509 can be inserted into the ground, so as to enhance the stability of the machine body 1 during subsequent operation. During the operation of inserting the anchor rod 509 into the ground, there is no need for the staff to hold a hammer to knock on the top of the anchor rod 509, so as to avoid strong vibration of the machine body 1, which is conducive to the subsequent proper operation and use of the volume 1, and the practical performance is enhanced.
