Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a combined drilling rod for mineral exploration. Background Technology

[0002] Drilling machines are indispensable equipment in the mining process. They are core tools in geological drilling, mineral resource exploration, and engineering surveying, and their performance directly affects drilling efficiency, cost, and safety.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222207822U, which discloses a combined drill rod for a mining drilling machine. The drill rod includes a first drill rod, a second drill rod, and a drill bit. The first drill rod is mounted on top of the second drill rod, and the drill bit is fixedly connected to the bottom of the second drill rod. An installation assembly is provided on the first drill rod, comprising an installation rod and two positioning sliders. Through the cooperation of the installation rod, the two positioning sliders, two limiting plates, a connecting plate, and two springs, the two positioning sliders slide laterally within their corresponding positioning grooves, thus limiting the installation rod. The two limiting plates reset under the action of the two springs, thereby facilitating the limiting and fixing of the two positioning sliders.

[0004] When the above-mentioned device is in use, after the first drill rod and the second drill rod are fixed, due to the limitation of the limit plate, if disassembly is required, it is necessary to release the positioning slider limit through the hole sealed by the sealing plate. If groundwater and mud and sand are present during the drilling process, they will inevitably enter the hole, which will lead to the problem of disassembly difficulties. Utility Model Content

[0005] The purpose of this utility model is to provide a combined drilling rod for mineral exploration to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined drilling rod for mineral exploration, comprising a core rod one and a core rod two, wherein the core rod one and the core rod two are arranged opposite to each other, and both the core rod one and the core rod two are hexagonal prisms. The same connecting component is installed at the ends of the core rod one and the core rod two that are close to each other. The connecting component includes a connecting column coaxially fixed to one bottom end of the core rod one, and the connecting column is also set as a hexagonal prism. The outer wall of the top of the core rod two is provided with a receiving groove adapted to the connecting column. The connecting column is provided with a horizontally arranged mounting hole, and a limiting structure is installed inside the mounting hole. The limiting structure includes a fixing screw, a spring, a mounting block, a moving screw, a clearance hole, and a reinforcing ring.

[0007] As a further preferred embodiment of this technical solution, a threaded groove is provided on both sides of the inner wall of the mounting hole at the bottom of the connecting column. The fixing screw is threaded into one of the threaded grooves. The spring is fixedly connected to the outer wall of the fixing screw on the side near the second core rod. The end of the spring away from the fixing screw is fixedly connected to a mounting block. The mounting block is slidably connected inside the threaded groove. The moving screw is rotatably connected to the outer wall of the mounting block on the side away from the spring and forms a transmission engagement with the other threaded groove. The clearance hole is opened inside the second core rod and is set directly opposite the moving screw. A reinforcing ring is coaxially fixed to the outer edge of the bottom outer wall of the first core rod. A clearance groove adapted to the reinforcing ring is opened on the outside of the second core rod.

[0008] After connecting the two core rods, ensure a strong enough seal between the moving screw and the clearance hole to effectively prevent external mud and sand from contacting the moving screw and spring, thus improving practicality. Grasp core rod two and align its top receiving groove with the bottom connecting post of core rod one, and align the clearance hole inside core rod two with the mounting groove inside the bottom connecting post of core rod one. Then, fully insert the connecting post into the receiving groove. At this point, the moving screw will be directly facing the clearance hole. Use a wrench to twist the moving screw, causing it to move outward along the mounting groove inside the connecting post. Then, the moving screw passes through the clearance hole at the top of core rod two and enters the clearance hole of its outer tube. The positions of core rod one and core rod two will be restricted, and this design also ensures that the moving screw will not detach from the outside. Disassembly is simple; just twist the moving screw in the opposite direction. Even if impurities enter the mounting groove of the connecting post, the obscured fixing screw can be removed for easy cleaning.

[0009] As a further preferred embodiment of this technical solution, an annular groove is provided on the outer circumference of the movable screw near the clearance hole, and a rubber sleeve is bonded inside the annular groove. The rubber sleeve and the clearance hole are interference fit.

[0010] As a further preferred embodiment of this technical solution, a conveying assembly is installed on the outside of both the first core rod and the second core rod. The conveying assembly includes an outer tube that is slidably connected to the outside of the first core rod, and a spiral blade is fixedly connected to the outer circumference of the outer tube.

[0011] As a further preferred embodiment of this technical solution, a horizontally arranged connecting bolt is slidably inserted into the outer circumference of the outer tube, and a threaded hole adapted to the connecting bolt is opened inside the core rod.

[0012] If the outer tube becomes unusable due to damage during use, the connecting bolts can be turned with a wrench. The connecting bolts will then move outward along the threaded hole they mate with. At this point, the outer tube will not be restricted and can be removed for replacement. It does not need to be completely discarded, which helps to save resources.

[0013] As a further preferred embodiment of this technical solution, a horizontally arranged protective ring is fixedly connected to the outer circumference of the outer tube, and the end of the connecting bolt is exactly inside the protective ring.

[0014] As a further preferred embodiment of this technical solution, a drill bit is connected to one end of the bottom of the second core rod via a tapered wire.

[0015] This utility model provides a combined drill pipe for mineral exploration, which has the following advantages:

[0016] (1) By setting up a connecting component, this utility model ensures that the sealing of the moving screw and the clearance hole is strong enough after the connection of the two core rods is completed, effectively preventing external mud and sand from contacting the moving screw and the spring, which is beneficial to improving practicality. Grasp the second core rod so that the receiving groove at its top is aligned with the connecting post at the bottom of the first core rod, and align the clearance hole inside the second core rod with the mounting groove inside the connecting post at the bottom of the first core rod. Then, fully insert the connecting post into the receiving groove. At this time, the moving screw will be facing the clearance hole. Use a wrench to turn the moving screw so that it moves outward along the mounting groove inside the connecting post. Then, the moving screw passes through the clearance hole at the top of the second core rod and enters the clearance hole of its outer tube. The positions of the first core rod and the second core rod will be restricted. This design also ensures that the moving screw will not fall out of the outside. When disassembling, simply turn the moving screw in the opposite direction. Even if impurities enter the mounting groove of the connecting post, the fixed screw that is covered can be removed for easy cleaning.

[0017] (2) By setting up a transmission component, if the outer tube is damaged and cannot be used due to use, the connecting bolt can be turned with a wrench. The connecting bolt will then move outward along the threaded hole that it mates with. At this time, the outer tube will not be restricted and can be removed for replacement. It does not need to be completely discarded, which is conducive to saving resources. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a combined drilling rod for mining exploration includes a core rod 1 and a core rod 2. The core rod 1 and the core rod 2 are arranged opposite to each other, and both core rod 1 and the core rod 2 are hexagonal prisms. The same connecting component 4 is installed at the ends of the core rod 1 and the core rod 2 that are close to each other. The connecting component 4 includes a connecting post 402 coaxially fixed to one end of the bottom of the core rod 1, and the connecting post 402 is also set as a hexagonal prism. The outer wall of the top of the core rod 2 has a receiving groove 401 adapted to the connecting post 402. The connecting post 402 has a horizontally set mounting hole inside, and a limiting structure is installed inside the mounting hole. The limiting structure includes a fixing screw 403, a spring 404, a mounting block 405, a moving screw 406 (which can be made of tungsten cobalt alloy to avoid damage due to shear force during use), an avoidance hole 408, and a reinforcing ring 409.

[0025] A threaded groove is provided on both sides of the inner wall of the mounting hole at the bottom of the connecting column 402. The fixing screw 403 is threaded into one of the threaded grooves. The spring 404 is fixedly connected to the outer wall of the fixing screw 403 near the core rod 2. The end of the spring 404 away from the fixing screw 403 is fixedly connected to the mounting block 405. The mounting block 405 is slidably connected inside the threaded groove. The moving screw 406 is rotatably connected to the outer wall of the mounting block 405 away from the spring 404 and forms a transmission engagement with the other threaded groove. The clearance hole 408 is opened inside the core rod 2 and is set directly opposite the moving screw 406. A reinforcing ring 409 is coaxially fixed to the outer edge of the bottom outer wall of the core rod 1. A clearance groove adapted to the reinforcing ring 409 is opened on the outside of the core rod 2.

[0026] An annular groove is provided on the outer circumference of the movable screw 406 near the clearance hole 408, and a rubber sleeve 407 is bonded inside the annular groove. The rubber sleeve 407 and the clearance hole 408 are interference fit, which can fill the gap and further improve the sealing effect.

[0027] Grasp the second core rod 2 and align its top receiving groove 401 with the bottom connecting post 402 of the first core rod 1. Align the clearance hole 408 inside the second core rod 2 with the mounting groove inside the bottom connecting post 402 of the first core rod 1. Then, fully insert the connecting post 402 into the receiving groove 401. At this time, the moving screw 406 will be directly facing the clearance hole 408. Use a wrench to turn the moving screw 406 so that it moves outward along the mounting groove inside the connecting post 402. Then, the moving screw 406 passes through the clearance hole 408 at the top of the second core rod 2 and enters the clearance hole 408 of its outer tube 501. The positions of the first core rod 1 and the second core rod 2 will be restricted. This design also ensures that the moving screw 406 will not come out of the outside. When disassembling, simply turn the moving screw 406 in the opposite direction. Even if impurities enter the mounting groove of the connecting post 402, the fixed screw 403 that is covered can be removed for easy cleaning.

[0028] like Figure 1 and Figure 2 As shown, a conveying assembly 5 is installed on the outside of both core rod 1 and core rod 2. The conveying assembly 5 includes an outer tube 501 that is slidably connected to the outside of core rod 1, and a spiral blade is fixedly connected to the outer circumference of the outer tube 501.

[0029] The outer tube 501 has a horizontally set connecting bolt 502 that is slidably inserted into its outer circumference, and the core rod 1 has a threaded hole 503 that is compatible with the connecting bolt 502.

[0030] A horizontally arranged protective ring 504 is fixedly connected to the outer circumference of the outer tube 501. The end of the connecting bolt 502 is located inside the protective ring 504, which can replace the bolt 502 to bear the soil friction and prevent the bolt 502 from loosening.

[0031] If the outer tube 501 becomes unusable due to damage during use, the connecting bolt 502 can be turned with a wrench. The connecting bolt 502 will then move outward along the threaded hole 503 that it mates with. At this time, the outer tube 501 will not be restricted and can be removed for replacement. It does not need to be completely discarded, which helps to save resources.

[0032] like Figure 1 and Figure 2 As shown, the bottom end of the core rod 2 is connected to the drill bit 3 via a tapered wire.

[0033] This utility model provides a combined drill rod for mineral exploration, the specific working principle of which is as follows:

[0034] During drill rod assembly, grasp the second core rod 2 and align its top receiving groove 401 with the bottom connecting post 402 of the first core rod 1. Align the clearance hole 408 inside the second core rod 2 with the mounting groove inside the bottom connecting post 402 of the first core rod 1. Then, fully insert the connecting post 402 into the receiving groove 401. At this point, the moving screw 406 will be aligned with the clearance hole 408. Use a wrench to turn the moving screw 406, moving it outward along the mounting groove inside the connecting post 402. Finally, the moving screw 406 passes through the core rod. The clearance hole 408 at the top of the second core rod 2 enters the clearance hole 408 of the outer tube 501, which restricts the position of the core rod 1 and the core rod 2. This design also ensures that the moving screw 406 will not come out of the outside. When disassembling, simply twist the moving screw 406 in the opposite direction. Even if impurities enter the mounting groove of the connecting post 402, the fixed screw 403 that is covered can be removed for easy cleaning. The rubber sleeve 407 at the end of the moving screw 406 can also fill the gap.

[0035] If the outer tube 501 becomes unusable due to damage during use, the connecting bolt 502 can be turned with a wrench. The connecting bolt 502 will then move outward along the threaded hole 503 that it mates with. At this time, the outer tube 501 will not be restricted and can be removed for replacement. It does not need to be completely discarded, which helps to save resources.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
