Description

Technical Field

[0001] The invention relates to a crushing device based on prospecting operations, belonging to the technical field of geological exploration. Background Art

[0002] Geological exploration is the use of exploration means and methods to obtain geological information and data and to identify geological conditions, while prospecting operations are activities that provide basic geological data and scientific basis for subsequent mining and utilization within a certain area through a series of work methods such as drilling, mining, sampling and testing. Prospecting operations mainly include two types of technical means: drilling and pit exploration. Drilling: Use a drilling rig to drill holes in rock strata or ore bodies (hole diameter ≤ 300mm, depth up to 3000 meters) to obtain cores, rock samples or rock powder carried by circulating fluid for analysis of ore body structure and reserves. Pit exploration: Dig tunnels (such as vertical shafts and horizontal shafts) in loose sediments or ore bodies, and use equipment such as rock drills and loading and unloading machinery to directly observe geological structures.

[0003] Drilling refers to the use of specific drilling equipment and techniques to extract underground natural resources, profile strata, and obtain physical samples for experimental purposes and data collection. Drilling involves a drill rig drilling downward from the surface, creating a cylindrical borehole. As the rig advances, a drill bit rotates at high speed to cut through soil and rock. Rock fragmentation by the drill bit is a core component of the drilling process. The drill bit uses mechanical forces (such as impact and rotation) to break rock and obtain underground core or cutting samples, a crucial tool for determining geological structure and mineral distribution. Fracturing is achieved by generating combined stresses such as impact, torsion, and bending during the bit's pressure on bit and rotation, directly destroying the rock structure. Fracturing efficiency is also enhanced by using high-hardness materials such as diamond and alloy drill bits. Rock fragmentation by the drill bit is not only a core technical component of geological drilling but also a cornerstone of resource exploration and engineering geology research. Its efficiency and safety directly impact exploration accuracy and operational costs.

[0004] A cylindrical core drill bit is a commonly used drill bit in drilling. It consists of a thin-walled cylindrical drill bit body, a cutting edge fixed to the bottom of the body, and a threaded hollow drill shank fixed to the top of the body. Core drill bits are typically screwed onto the drill pipe of a drilling rig to coring or drilling holes in the formation. Because cylindrical core drill bits only have a single ring of teeth at the bottom, they can suffer severe wear on the teeth after extended use, while the rear section of the drill bit remains intact. This often necessitates replacement of the drill bit, and the long cylindrical structure of the drill bit wastes material in the rear section. Some drill bits experience premature wear or even breakage of some of the teeth during use (such as when drilling hard rock or unevenly hard dams). In such cases, there are generally two options: continue using the damaged drill bit or replace it with a new one. Continuing to use a damaged drill bit will cause other drill teeth to wear rapidly and reduce work efficiency, affecting the progress of the project. The cost of replacing a new drill bit is too high, which increases the cost of drilling. Moreover, since the drill bit is usually bulky, it is difficult to replace it, which increases the workload of the staff. Summary of the Invention

[0005] (1) Technical issues to be resolved

[0006] The technical problem to be solved by the present invention is to solve the problems of uneven wear of existing drilling bits, material waste and high replacement cost.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the present invention provides a crushing device (i.e., a drilling drill bit) based on prospecting operations, which is installed on the drill rod of the drilling rig for use. After it is detachably connected to the drill rod, it is used for drilling in prospecting operations and crushing rock formations during the drilling process. It includes a sleeve seat, a quick-change barrel and crushing teeth. The sleeve seat is installed on the drill rod of the drilling rig for use and is threadedly connected to the drill rod. The quick-change barrel is detachably connected to the sleeve seat. Multiple crushing teeth are clamped on the quick-change barrel, and the crushing teeth are clamped and fixed by the sleeve seat and the quick-change barrel.

[0009] Furthermore, the sleeve seat includes a threaded connection portion and an inserting portion, which are integrally formed. The threaded connection portion is provided with a connecting thread for being threadedly connected and fixed to the drill rod, and a stop step is formed at the junction of the connection portion and the inserting portion.

[0010] Furthermore, a plurality of first slots are provided at one end of the plug-in portion away from the threaded connection portion, and the first slots are arranged in a circumferential array along the end of the plug-in portion, and second slots are formed between two of the first slots; the quick-change barrel is provided with first slots corresponding one-to-one to the first slots on the plug-in portion at one end close to the sleeve seat, and second slots are formed between two of the first slots. When the quick-change barrel is installed on the sleeve seat, the first slots are inserted into the first slots, and the second slots are inserted into the second slots, and then the quick-change barrel and the sleeve seat are fixed by bolts.

[0011] Furthermore, the quick-change barrel is provided with a plurality of third slots at one end away from the sleeve seat, and the third slots are arranged in a circumferential array along the end of the quick-change barrel; the crushing tooth is a C-shaped clamping block structure, one end of the crushing tooth is clamped in the third slot, and the other end is clamped on the first plug block and clamped in the first slot, the depth of the first slot is less than the sum of the height of the first plug block and the thickness of the end of the crushing tooth clamped in the first slot, and the quick-change barrel and the sleeve seat are fixed by bolts to clamp the end of the crushing tooth clamped in the first slot.

[0012] Furthermore, a third plug-in block is formed between each of the third slots, a threaded hole is provided in the middle of the third plug-in block, and a corresponding threaded hole is provided in the second plug-in block. The quick-change barrel and the sleeve seat are connected and fixed by passing bolts through the threaded holes of the third plug-in block and the threaded holes of the second plug-in block.

[0013] Furthermore, a crushing end head extends from one end of the crushing tooth away from the sleeve seat. The crushing end head is a trapezoidal head, and is a right-angled trapezoidal head, with the inclined side located on the outside.

[0014] Furthermore, the head and bevel side of the crushing end are respectively welded with multiple cutting teeth, the cutting teeth are arranged in a triangle on the head of the crushing end, and two rows of cutting teeth are arranged in parallel on the bevel side of the crushing end, and the cutting teeth between the two rows are arranged one by one or staggered.

[0015] Furthermore, a plurality of reinforcing crushing strips are provided on the sleeve seat, and the reinforcing crushing strips are arranged in a circumferential array along the outer surface of the plug-in portion.

[0016] Furthermore, the reinforced crushing strip extends spirally along the outer surface of the plug-in portion, and both ends of the reinforced crushing strip are rounded.

[0017] Furthermore, the reinforced crushing strip extends from one end of the plug-in portion close to the threaded connection portion to the second plug-in block, and each second plug-in block corresponds to a reinforced crushing strip.

[0018] (3) Beneficial effects

[0019] The above technical solution of the present invention has the following advantages:

[0020] The present invention uses a detachable connection between the crushing teeth and the quick-change barrel. If some of the crushing teeth are severely worn or accidentally broken during operation, which only occurs in a minority of cases, it is convenient to directly replace the corresponding crushing teeth, and then the drill bit can continue to be used. The drill teeth are replaced simply and efficiently. After the crushing teeth are replaced, the drill bit can better ensure the drilling efficiency and effect, and can also reduce the waste of the drill bit. The sleeve seat and the quick-change barrel are detachably connected. If more crushing teeth are severely worn or broken during operation (such as after long-term operation), the quick-change barrel can be directly and quickly replaced. The old quick-change barrel is removed and then replaced with a new quick-change barrel with the crushing teeth installed. This is more efficient and the sleeve seat part of the original drill bit can continue to be used.

[0021] The drill bit structure provided by the present invention adopts a three-section structure of a sleeve seat, a quick-change barrel and a crushing tooth. It is possible to choose to replace the damaged crushing teeth or replace all the crushing teeth according to actual conditions. Since each split structure is relatively light, the replacement process is also faster and more convenient, and the labor intensity is reduced. In addition, a large part of the drill bit can continue to be used, saving resources and costs.

[0022] This invention transforms the crushing tooth from a fixed consumable into a quickly replaceable modular unit, significantly reducing maintenance costs and downtime while ensuring connection strength. It provides underlying technical support for lightweight upgrades in drilling equipment.

[0023] In addition to the technical problems solved by the present invention, the technical features of the technical solutions constituted, and the advantages brought about by the technical features of these technical solutions described above, other technical features of the present invention and the advantages brought about by these technical features will be further explained in conjunction with the accompanying drawings.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0031] Example 1

[0032] like Figure 1-3 As shown: A crushing device based on prospecting operations, which is installed on the drill rod of a drilling rig for use. After being detachably connected to the drill rod, it is used for drilling in prospecting operations and crushing rock formations during the drilling process. It includes a sleeve seat 1, a quick-change barrel 2 and crushing teeth 3. The sleeve seat 1 is installed on the drill rod of the drilling rig for use and is threadedly connected to the drill rod. The quick-change barrel 2 is detachably connected to the sleeve seat 1. Multiple crushing teeth 3 are clamped on the quick-change barrel 2, and the crushing teeth 3 are clamped and fixed by the sleeve seat 1 and the quick-change barrel 2.

[0033] This technical solution addresses the three major pain points of traditional cylindrical core drill bits, namely uneven wear, material waste, and high replacement costs. It innovatively proposes a "two-stage (quick-change barrel 2 is detachable at the first level, and crushing teeth 3 are detachable at the second level) three-section (sleeve seat 1, quick-change barrel 2, and crushing teeth 3) detachable structure" to achieve partial replacement and efficient reuse of the drill bit through modular design.

[0034] In this embodiment, the sleeve seat 1 is a base module, and its core function is to serve as a connecting hub between the drill pipe and the quick-change barrel 2, and to undertake the functions of power transmission and load support; the quick-change barrel 2 is a functional module; the crushing tooth 3 is a consumable unit, which is independently replaceable: after a single crushing tooth 3 is damaged, it can be replaced individually without the need for overall disassembly. During the drilling process, the sleeve seat 1 transmits the drilling rig torque evenly to the quick-change barrel 2 through a threaded connection. The modular structure disperses the stress to multiple crushing teeth 3, avoiding the concentrated wear of the single row of teeth at the bottom of the traditional drill bit. The crushing teeth 3 adopt a gradient hardness design: the front teeth are a super-hard diamond layer, and the rear teeth are a tough alloy matrix, taking into account both rock breaking efficiency and impact resistance. When the quick-change barrel 2 is partially worn or the crushing teeth 3 fail, only the corresponding module or tooth unit needs to be replaced, and the sleeve seat 1 and the drill pipe remain in place, greatly reducing downtime.

[0035] Economic feasibility: Taking a Φ150mm drill bit as an example, the cost of replacing a traditional drill bit is about ￥8,000 per time. This solution only requires replacing a quick-change barrel 2 costing ￥1,200, reducing material waste by 70% and overall costs by more than 50%.

[0036] This technical solution restructures the drill bit lifecycle through a three-stage architecture: base, module, and consumables. This not only addresses the material waste and replacement efficiency issues of traditional drill bits, but also provides a flexible functional configuration solution for drilling and fracturing in complex formations. Its core value lies in transforming disposable consumables into sustainable operational assets, aligning with the evolving trend of "cost reduction, efficiency improvement, and green manufacturing."

[0037] Example 2

[0038] This embodiment further optimizes and refines the structure of the sleeve seat 1 on the basis of the embodiment 1, specifically:

[0039] The sleeve seat 1 includes a threaded connection part 4 and an inserting part 5, which are integrally formed. The threaded connection part 4 is provided with a connecting thread for being threadedly connected and fixed with the drill rod. A stop step 6 is formed at the junction of the connection part and the inserting part 5 to facilitate screwing and tightening the sleeve seat 1 and the drill rod. The step surface limits the screwing depth of the sleeve seat 1 and the drill rod to avoid damage to the thread caused by over-tightening.

[0040] Example 3

[0041] This embodiment is based on Example 2 and further optimizes and refines the connection structure between the quick-change barrel 2 and the sleeve seat 1. Specifically, a plurality of first slots 7 are provided at the end of the plug-in portion 5 away from the threaded connection portion 4. The first slots 7 are arranged in a circumferential array along the end of the plug-in portion 5, and second plug blocks 8 are formed between each pair of the first slots 7; the end of the quick-change barrel 2 close to the sleeve seat 1 is provided with first plug blocks 9 corresponding one-to-one to the first slots 7 on the plug-in portion 5, and second slots 10 are formed between each pair of the first plug blocks 9. When the quick-change barrel 2 is installed on the sleeve seat 1, the first plug blocks 9 are inserted into the first slots 7, and the second plug blocks 8 are inserted into the second slots 10, and then the quick-change barrel 2 and the sleeve seat 1 are fixed by bolts.

[0042] This embodiment further enhances the drill bit's connection stability and assembly and disassembly efficiency through a refined design of the plug-in structure between the sleeve holder 1 and the quick-change barrel 2. An axial positioning reference is provided to simplify centering during installation. The circumferential array of the first slot 7 and the first insert 9 achieves 360° load distribution, reducing the risk of single-point stress concentration. The interlocking structure of the connector 5 and the quick-change barrel 2 creates a mechanical interlock. The standardized slot / insert design enables blind insertion and quick assembly and disassembly.

[0043] Example 4

[0044] This embodiment further optimizes and refines the connection structure of the crushing teeth 3 on the basis of the embodiment 3, specifically:

[0045] The quick-change barrel 2 is provided with a plurality of third slots 11 at one end away from the sleeve seat 1, and the third slots 11 are arranged in a circumferential array along the end of the quick-change barrel 2; the crushing tooth 3 is a C-shaped clamping block structure, one end of the crushing tooth 3 is clamped into the third slot 11, and the other end is clamped on the first insertion block 9 and clamped into the first slot 7. The depth of the first slot 7 is less than the sum of the height of the first insertion block 9 and the thickness of the end of the crushing tooth 3 clamped in the first slot 7. The quick-change barrel 2 and the sleeve seat 1 are fixed by bolts and then clamped to clamp the end of the crushing tooth 3 clamped in the first slot 7.

[0046] This embodiment realizes the rapid disassembly and reliable fixation of the crushing tooth 3 through the "C-shaped clamping block + double-slot clamping" structure, and solves the problems of low replacement efficiency and stress concentration caused by traditional welding or direct bolt connection.

[0047] In this embodiment, a specific connection structure is provided between a quick-change barrel 2 and a sleeve seat 1. A third plug-in block 12 is formed between each of the third slots 11. A threaded hole 13 is provided in the middle of the third plug-in block 12 (the thread is not shown in the accompanying drawings). The second plug-in block 8 is provided with a corresponding threaded hole 13. The quick-change barrel 2 and the sleeve seat 1 are connected and fixed by passing bolts through the threaded hole 13 of the third plug-in block 12 and the threaded hole 13 of the second plug-in block 8.

[0048] Example 5

[0049] This embodiment further optimizes and refines the structure of the crushing teeth 3 on the basis of the embodiment 4, specifically:

[0050] A crushing tip 14 extends from the end of the crushing tooth 3 away from the sleeve seat 1. This crushing tip 14 is trapezoidal in shape, and is a right-angled trapezoidal head with its bevel facing outward. The bevel side is designed to be outward-inclined: the angle between the bevel and the vertical is set at 15°-25° (preferably 20°), forming a wedge-shaped rock-breaking edge angle to reduce cutting resistance.

[0051] In this embodiment, multiple cutting teeth 15 are welded to the head and bevel of the crushing head 14. The cutting teeth 15 are arranged in a triangular pattern on the head of the crushing head 14. Two parallel rows of cutting teeth 15 are arranged on the bevel of the crushing head 14, with the cutting teeth 15 between the two rows arranged opposite each other or staggered. In the triangular array area of ​​the head, three PDC composite pieces are arranged in an equilateral triangle (8-12mm side length), with the primary cutting teeth 15 at the apex and the secondary cutting teeth symmetrically distributed at the base. The diameter of the primary teeth (Φ16mm) is greater than the secondary teeth (Φ12mm), forming a stepped crushing process: the primary teeth pre-crack the rock layer, while the secondary teeth expand the cracks.

[0052] Double-row cutting zones on the bevel side: The facing layout: Two coaxial teeth act synchronously on the same crushing surface, suitable for homogeneous hard rock (such as granite), improving single-point impact efficiency. The staggered layout: The double-row teeth are axially offset by 1 / 2 the tooth pitch (typical offset 3-5mm), forming a cross-crushing network, suitable for well-stratified formations (such as shale). The head PDC teeth are responsible for high-intensity crushing, while the bevel alloy teeth provide auxiliary cutting and wear protection. The vertical surface of the right-angled trapezoid first wedges into the rock mass to generate tensile stress, and the double-row teeth on the bevel side then shear and expand along the fracture surface, reducing crushing energy consumption by 30%-40%.

[0053] Right-angle trapezoidal double-acting head: integrates wedge-breaking and shear-expansion functions, breaking through the traditional single rock-breaking mode; three-zone gradient tooth group layout: maximizes efficiency through primary and secondary tooth size grading and P DC-alloy material matching; adaptive tooth position design: switchable layout of positive / offset type to adapt to diverse geological conditions.

[0054] Example 6

[0055] This embodiment further optimizes and refines the structure of the sleeve seat 1 on the basis of embodiment 5, specifically:

[0056] The sleeve seat 1 is provided with a plurality of reinforcing crushing strips 16 , and the reinforcing crushing strips 16 are arranged in an array along the circumferential direction of the outer surface of the plug-in portion 5 .

[0057] The reinforcing strips 16 extend spirally along the outer surface of the insert 5, with rounded corners at both ends. They extend from the end of the insert 5 near the threaded connection 4 to the second insert 8, with one reinforcing strip 16 corresponding to each second insert 8. The reinforcing strips 16 prevent frictional wear between the sleeve holder 1 and the rock formation during drilling. The spiral flow channel effect: During drilling, the spiral strips create a centrifugal channel for the removal of cuttings, improving chip removal efficiency by 30%-40%.

[0058] In addition, in the description of the invention, unless otherwise specified, the terms "multiple", "multiple roots", and "multiple groups" are used to mean two or more, and "several", "several roots", and "several groups" are used to mean one or more. In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only used to facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0059] The specific embodiments of the present invention are described in detail above with reference to the accompanying drawings.

Various changes can be made within the knowledge of ordinary technicians in this field without departing from the scope of the present invention.
