Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a novel geological exploration drilling device. Background Technology

[0002] In geological exploration, drilling is a crucial method for obtaining underground geological samples and understanding stratigraphic structure. Traditional geological exploration drilling equipment has several shortcomings. For example, the equipment is inconvenient to move and secure; some units require large hoisting equipment for transport, and once at the work site, they are difficult to quickly and stably anchor, impacting work efficiency. Furthermore, the raising, lowering, and rotating control of the drill rod during drilling is not precise enough, affecting drilling depth and sampling quality. In addition, the soil generated during drilling easily adheres to the drill rod, increasing its weight, hindering normal raising and lowering, and potentially interfering with subsequent sample analysis; however, existing equipment lacks effective methods for cleaning the soil from the drill rod. Utility Model Content

[0003] The purpose of this invention is to provide a novel geological exploration drilling device to solve at least one of the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel geological exploration drilling device, comprising a base, wherein the base is provided with universal wheels with self-locking function around its bottom, and a fixing plate is fixedly connected to the base around its bottom, wherein threaded holes are provided through the fixing plates, and fixing screws are threadedly connected to the threaded holes, wherein a handle is fixedly connected to the top of the fixing screws, and the bottom of the fixing screws is set in a pointed cone shape.

[0005] Preferably, a U-shaped frame is fixedly connected to the top of the base, and a first motor is provided on the top of the U-shaped frame. The output end of the first motor is fitted with a reciprocating lead screw through a coupling.

[0006] Preferably, the inner cavity of the U-shaped frame is fixedly connected to a limiting rod, and a connecting plate is fitted around the outer ring of the limiting rod and the reciprocating lead screw. The top of the connecting plate is provided with a lead screw hole and a limiting hole that are compatible with the reciprocating lead screw and the limiting rod.

[0007] Preferably, a second motor is provided on the top of the connecting plate, and a drill bit is fixedly connected to the output shaft of the second motor. The connecting plate is fitted into the middle of the reciprocating lead screw and the limiting rod through the lead screw hole and the limiting hole.

[0008] Preferably, a support frame is fixedly connected to both sides of the top of the base, and a square plate is provided on one side of each of the two support frames.

[0009] Preferably, a hydraulic cylinder is provided on one side of each of the two square plates, and a scraper is fixedly connected to one side of the output end of each of the two hydraulic cylinders.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. In this utility model, the hydraulic cylinders on the support frames on both sides of the base push the mud scraper, which can clean the attached mud in time when the drill bit rises. This not only avoids mud from being brought out and polluting the working environment, but also reduces the load on the drill bit, which is conducive to the smooth raising and lowering of the drill bit, extends the service life of the drill bit, reduces equipment wear and tear costs, and also improves the working environment of the operators.

[0012] 2. In this utility model, the first motor drives the reciprocating lead screw to rotate, which, combined with the limiting rod, restricts the rotation of the connecting plate, enabling the connecting plate to move precisely up and down along the axial direction. At the same time, the second motor on the connecting plate drives the drill bit to rotate at high speed. This combination method achieves precise control of drilling depth and speed, which helps to obtain more accurate geological samples, improves the accuracy of geological exploration, and provides a reliable basis for subsequent geological analysis.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1-4The invention relates to a novel geological exploration drilling device, comprising a base 1, with self-locking casters 2 on all four sides of the base 1. Fixing plates 3 are fixedly connected to all four sides of the base 1, and threaded holes 4 are drilled through each fixing plate 3. Fixing screws 5 are threaded into each threaded hole 4, and handles 6 are fixedly connected to the tops of each fixing screw 5. The bottoms of the fixing screws 5 are all conical. This design of the casters 2 allows the device to move easily during transportation and relocation. Upon arrival at the designated work site, the self-locking function quickly fixes the device in position, preventing displacement during drilling. When the device is fixed, the operator rotates the handles 6 to screw the fixing screws 5 downwards into the ground. The conical bottoms better embed into the ground, enhancing the stability of the device and adapting to different ground conditions, such as soft soil or hard rock.

[0020] Furthermore, a U-shaped frame 7 is fixedly connected to the top of the base 1. A first motor 8 is installed on the top of the U-shaped frame 7. A reciprocating lead screw 9 is fitted onto the output end of the first motor 8 through a coupling. A limit rod 10 is fixedly connected to the inner cavity of the U-shaped frame 7. A connecting plate 11 is fitted onto the outer ring of the limit rod 10 and the reciprocating lead screw 9. The top of the connecting plate 11 has a lead screw hole 12 and a limit hole 13 that are compatible with the reciprocating lead screw 9 and the limit rod 10. When the first motor 8 starts, it drives the reciprocating lead screw 9 to rotate. Since the connecting plate 11 cooperates with the reciprocating lead screw 9 through the lead screw hole 12 and the limit hole 13 is fitted onto the limit rod 10, the limit rod 10 restricts the rotation of the connecting plate 11, so that the connecting plate 11 can only move up and down along the axial direction of the reciprocating lead screw 9 and the limit rod 10, thereby realizing the height control of the drill bit 15.

[0021] Furthermore, a second motor 14 is provided on the top of the connecting plate 11. The output shaft of the second motor 14 is fixedly connected to the drill bit 15. The connecting plate 11 is fitted into the middle of the reciprocating lead screw 9 and the limiting rod 10 through the lead screw hole 12 and the limiting hole 13. During the up and down movement of the connecting plate 11, the second motor 14 is started, driving the drill bit 15 to rotate at high speed to carry out drilling operations underground. Through the coordinated work of the first motor 8 and the second motor 14, the drilling depth and speed can be precisely controlled, improving the accuracy and efficiency of drilling operations.

[0022] Furthermore, support frames 16 are fixedly connected to both sides of the top of the base 1. A square plate 17 is provided on one side of each of the two support frames 16. A hydraulic cylinder 18 is provided on one side of each of the two square plates 17. A scraper 19 is fixedly connected to one side of the output end of each of the two hydraulic cylinders 18. During drilling, when the drill rod rises, the hydraulic cylinder 18 is activated, pushing the scraper 19 closer to the drill rod. The scraper 19 can scrape off the soil attached to the drill bit 15, preventing the soil from being carried out with the drill bit 15 as it rises, thus avoiding pollution of the working environment. It also reduces the load on the drill bit 15 and facilitates the smooth raising and lowering of the drill bit 15.

[0023] In practical implementation, the device is first moved to the designated drilling location using the casters 2. Upon arrival, the ground conditions are observed. If the ground is relatively soft, the fixing screw 5 can be screwed downwards into the ground by rotating the handle 6 until the device is stably fixed. The first motor 8 is then started, driving the reciprocating screw 9 to rotate, causing the connecting plate 11 to move downwards along the limit rod 10. The drill bit 15 is then adjusted to a suitable starting drilling position. The second motor 14 is then started, driving the drill bit 15 to rotate at high speed, and drilling operations begin. During drilling, the lifting speed and depth of the drill bit 15 can be adjusted by controlling the forward and reverse rotation and speed of the first motor 8, according to actual needs. As the drill bit 15 rises, when the drill rod approaches the position of the scraper 19, the hydraulic cylinder 18 is activated, pushing the scraper 19 towards the drill rod. The scraper 19 contacts the drill bit 15, scraping off the soil adhering to the drill bit 15. The scraped soil can be cleaned up promptly to avoid accumulation at the work site.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
