[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1

[0029] Reference Figure 1 to Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a drilling rig, which can achieve the effect that artificial propulsion can be adjusted according to actual conditions under complex or unpredictable geological conditions, and reduce the risk of the drill bit 102d being stuck, including: a slide rail 102b is arranged at the upper end of the fixed seat 101, and the slide rail 102b is in the shape of a "U", and a positioning slider 102c is slidably connected therein, and a sliding frame 102a is fixedly connected to the lower end of the positioning slider 102c, and the sliding frame 102a is slidably connected to the inner side of the fixed seat 101 through the positioning slider 102c, and the sliding frame 102a is used to fix the drill bit 102d, so that the sliding frame 102a is driven to move by sliding the positioning slider 102c, thereby realizing the movement of the drill bit 102d;

[0030] A plurality of grooves are provided on the other side surface of the slide rail 102b, each groove represents a scale 102g, and a measuring bar 102f is provided at the rear end of the positioning slider 102c. By observing the scale 102g corresponding to the measuring bar 102f, the drilling depth of the drill bit 102d at this time can be judged, so that adjustments can be made according to actual conditions to reduce the risk of the drill bit 102d getting stuck.

[0031] Specifically, the fixing seat 101 is connected to the base 202 via a connecting sleeve 201, and rollers 203 are provided at the four corners of the base 202. The rollers 203 make the drilling rig more flexible during installation and adjustment, and can be quickly fine-tuned to ensure that the drilling rig is in the best working condition.

[0032] Example 2

[0033] Reference Figure 3 to Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a support unit 200 for a drilling rig, which solves the problem of poor stability of the roller 203 when the drilling rig is working, including four groups of "L"-shaped connecting frames 204c arranged inside the base 202, and connecting rods 205a are rotatably connected between the four groups of connecting frames 204c, and a transmission gear 205b and a connecting crank 205d are fixedly connected to the connecting rod 205a.

[0034] Furthermore, a worm 204b is rotatably connected to the base 202 via a rotating shaft 302b at the inner center position of the base 202, the tooth pitches of the four transmission gears 205b are all adapted to the worm 204b, and are meshedly connected to the worm 204b, and a motor 204a is arranged in the connecting sleeve 201, and the output end of the motor 204a passes through the upper surface of the base 202 and is connected to the worm 204b, so that under the drive of the motor 204a, the worm 204b rotates and drives the four transmission gears 205b to rotate at the same time.

[0035] Among them, through grooves 205c are formed on the front and rear surface of the base 202. The positions of the through grooves 205c are aligned with the four groups of connecting cranks 205d. While the transmission gear 205b rotates upward, it drives the connecting rod 205a to rotate. Then, the connecting rod 205a drives the connecting crank 205d to rotate downward. With the rotation between the connecting cranks 205d, the bottom of the support 301c on the support feet 205e installed at the other ends of the connecting cranks 205d will contact the ground. The support 301c is in a "C" shape and is slidably connected inside the transmission groove 301a. With the continuous rotation of the connecting crank 205d, the bottom of the support feet 205e will contact the ground and exert a downward pressure on the ground, thereby lifting the drilling rig to the required height. The bottoms of the four groups of support feet 205e serve as support points to evenly distribute the ground pressure, thereby stably fixing the drilling rig and ensuring that it will not displace or tilt during operation.

[0036] Embodiment 3

[0037] Refer to Figure 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a drilling rig, which solves the problem that the device is prone to tilt on soft soil. It includes the drilling rig in the above embodiment. The support 301c is in a "C" shape, and a return spring 301b is arranged inside it. The other end of the return spring 301b is fixedly connected to the inner bottom of the transmission groove 301a. The bottom of the support 301c exerts a downward pressure on the ground, so that the support 301c slides upward, resulting in the deformation of the return spring 301b being stretched, thereby storing elastic potential energy. When the connecting crank 205d moves upward and the downward pressure exerted by the bottom of the support 301c on the ground disappears, the return spring 301b will push the support 301c to reset.

[0038] Furthermore, at one side position of the support 301c at the inner bottom of the transmission groove 301a, two vertical plates 302a are arranged. A rotating shaft 302b is arranged between the two vertical plates 302a. A rotating gear 302c is fixedly connected to the outside of the rotating shaft 302b between the two vertical plates 302a. And a rack 301d is arranged at a position on the outside of the support 301c aligned with the rotating gear 302c. The rack 301d meshes with the rotating gear 302c, which enables the support 301c to drive the rotating gear 302c to rotate clockwise or counterclockwise when moving vertically upward or downward.

[0039] Among them, a first bevel gear 303a is provided on the outside of the rotating shaft 302b at one side of the vertical plate 302a, and a drilling rod 303b is rotatably connected to the bottom of the support leg 205e, and a second bevel gear 303c is provided on the upper end of the drilling rod 303b protruding from the transmission groove 301a. The first bevel gear 303a and the second bevel gear 303c are meshingly connected, and the part of the drilling rod 303b exposed at the bottom of the support leg 205e is spiral. During the drilling process, the soil is cut by rotation, which makes it easier to penetrate the ground, provide better grip, reduce the slippage of the drilling rod 303b in the soil, and achieve the effect of improving stability.

[0040] When in use, the motor 204a drives the worm 204b to rotate, and at the same time drives the four sets of transmission gears 205b to rotate, and the four sets of connecting cranks 205d rotate downward at the same time, exerting downward pressure on the ground. This pressure is transmitted to the ground through the bracket 301c. Because the bracket 301c is connected to the support foot 205e through the return spring 301b, the bracket 301c cannot be used as a support point. Under the factor of the device's own gravity, the bracket 301c will move vertically upward, and at the same time, the rack 301d set on one side drives the rotating gear 302c to rotate. Driven by the rotating shaft 302b, the first bevel gear 303a drives the second bevel gear 303c to rotate, driving the drilling rod 303b to cut the soil, providing additional stability by increasing the contact area and friction, and then the bottom of the support foot 205e contacts the ground, so as to provide secondary reinforcement to the device.
