Description

Technical Field

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

[0002] Geological exploration equipment refers to specialized mechanical equipment used in fields such as geological surveys, mineral resource exploration, and engineering geological investigation. Its core function is to obtain underground geological information through physical, chemical, or mechanical means, providing data support for resource development, engineering construction, and geological research.

[0003] The existing equipment is not convenient for stratifying the sampled soil. The sampled soil is mixed together, making it impossible to compare the soil quality results at different depths. The exploration accuracy is not high enough. Furthermore, the height of the drill rod cannot be adjusted as needed to meet the requirements for extracting soil samples at different depths. It is not flexible enough to use and it is not convenient to clean the drill rod after sampling.

[0004] The existing patent (publication number: CN222162484U) discloses a high-precision exploration device. This utility model features a drilling mechanism where the main body of a small backpack geological drill rig, the feed tube A, and the sampling tube B can be connected and disassembled. The length of the sampling drill rod can be adjusted by changing the number of feed tubes A to meet the needs of extracting soil samples at different depths, making it more flexible to use. The feed ports of feed tubes A and B are opened sequentially to extract and separate the soil from each tube for testing, avoiding soil mixing inside the drill rod. This allows for layered testing of soil samples to understand the soil conditions at different depths, resulting in higher exploration accuracy.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the sampling tubes A and B proposed in these patents are quite long. When sampling tubes A and B are connected, they cannot precisely match the sampling depth required for geological exploration, thus making it impossible to accurately control the sampling depth and affecting the accuracy of the geological exploration results.

[0006] Therefore, a geological exploration device with adjustable drilling depth is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a geological exploration device with adjustable drilling depth, which can solve the problem in the existing patent that the length of sampling pipe A and sampling pipe B is too long, and when sampling pipe A and sampling pipe B are connected, they cannot meet the sampling depth required for geological exploration, thus making it impossible to accurately control the sampling depth and affecting the accuracy of geological exploration results.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a geological exploration device with adjustable drilling depth, comprising a backpack-type geological drilling rig body, wherein a first drill rod and several second drill rods are provided at the bottom of the backpack-type geological drilling rig body, a positioning mechanism is provided on the surface of the first drill rod, and a limit mechanism is provided on both sides of the top of the positioning mechanism, and scale lines are opened on the surface of the first drill rod, wherein the number of scale lines is several and evenly distributed on the surface of the first drill rod;

[0009] The positioning mechanism includes a positioning ring, four scrapers, and two sliders. The two sliders are fixedly connected to the front and rear sides of the inner wall of the positioning ring, respectively. The scraper is fixedly connected to the slider on the side closest to the slider. The positioning ring is movably fitted onto the surface of the first drill rod.

[0010] Preferably, the limiting mechanism includes a threaded post, an anti-slip pad, and a limiting block. The threaded post is threadedly connected to the inside of the limiting block. The side of the anti-slip pad near the threaded post is fixedly connected to the threaded post, and the side of the anti-slip pad near the first drill rod is in close contact with the surface of the first drill rod.

[0011] Preferably, the first drill rod has grooves on both the front and rear sides, and the slider is slidably connected inside the grooves.

[0012] Preferably, the bottom of the positioning ring is fixedly connected to a scraper ring, the surface of the scraper ring is in movable contact with the surface of the first drill rod, and the bottom of the scraper ring is chamfered.

[0013] Preferably, the surface of the scraper block is in active contact with the inner wall of the groove, and both the scraper block and the scraper ring are made of white cast iron.

[0014] Preferably, the bottoms of both the first drill rod and the second drill rod are fixedly connected to threaded sleeves, and the top of the inner wall of the second drill rod is provided with a threaded groove, and the threaded sleeve is threadedly connected to the threaded groove.

[0015] Preferably, a raised ring is fixedly connected to the top of the second drill rod, and a rubber sealing gasket is fixedly connected to the top of the raised ring. A slot is provided at the bottom of the first drill rod, and the raised ring is movably inserted into the inside of the slot.

[0016] Preferably, the positioning ring is made of stainless steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting a positioning mechanism, allows the positioning ring to be locked at a suitable position on the surface of the first drill rod by observing the scale groove. This ensures that the length of several connected second drill rods, plus the length from the bottom of the first drill rod to the bottom of the positioning ring, matches the required drilling depth. During drilling, when the first and second drill rods enter the ground and the bottom of the positioning ring contacts the ground, the required drilling depth is reached, achieving precise control of the drilling depth. This solves the problem in existing patents where the lengths of sampling pipes A and B are too long, and when they are connected, they cannot precisely match the sampling depth required for geological exploration, thus affecting the accuracy of geological exploration results.

[0027] 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.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A geological exploration device with adjustable drilling depth includes a backpack-type geological drilling rig body 1. The bottom of the backpack-type geological drilling rig body 1 is provided with a first drill rod 2 and several second drill rods 4. The surface of the first drill rod 2 is provided with a positioning mechanism 3. Limiting mechanisms 9 are provided on both sides of the top of the positioning mechanism 3. The surface of the first drill rod 2 is provided with scale lines 6. The number of scale lines 6 is several and they are evenly distributed on the surface of the first drill rod 2.

[0030] The positioning mechanism 3 includes a positioning ring 301, four scrapers 302 and two sliders 303. The two sliders 303 are fixedly connected to the front and rear sides of the inner wall of the positioning ring 301, respectively. The scraper 302 is fixedly connected to the slider 303 on the side closest to the slider 303. The positioning ring 301 is movably sleeved on the surface of the first drill rod 2.

[0031] In this embodiment: when the first drill rod 2 is connected to several second drill rods 4 through the threaded sleeve 7 and the threaded groove 12, if there is a deviation between the total length and the required drilling depth, the scale line 6 on the surface of the first drill rod 2 can be observed, and the positioning ring 301 can be slid up and down along the slide groove 8 to adjust it to the target position. After adjusting to the target position, the threaded column 901 of the limiting mechanism 9 is rotated, and the anti-slip rubber pad 902 presses the surface of the first drill rod 2, locking the position through friction. At this time, the total length of the second drill rods 4 plus the distance from the bottom of the first drill rod 2 to the bottom of the positioning ring 301 is the set drilling depth. The backpack-type geological drilling rig body 1 drives the first drill rod 2 and the second drill rod 4 to drill into the formation. When the bottom of the positioning ring 301 contacts the ground, it indicates that the preset depth has been reached, and the machine is immediately stopped to achieve precise control of the drilling depth. At the same time, the top protrusion ring 10 of the second drill rod 4 cooperates with the bottom slot 13 of the first drill rod 2, and the rubber sealing gasket 11 prevents external mud from seeping into the internal sample through the threaded connection when the first drill rod 2 and the second drill rod 4 are pulled out, thus affecting the accuracy of the sample. This solves the problem in the existing patent that the length of the sampling tube A and sampling tube B is too long, and when the sampling tube A and sampling tube B are connected, they cannot meet the sampling depth required for geological exploration, which makes it impossible to accurately control the sampling depth and affects the accuracy of the geological exploration results.

[0032] Specifically, such as Figure 3As shown, the limiting mechanism 9 includes a threaded post 901, an anti-slip pad 902, and a limiting block 903. The threaded post 901 is threadedly connected to the inside of the limiting block 903. The side of the anti-slip pad 902 near the threaded post 901 is fixedly connected to the threaded post 901, and the side of the anti-slip pad 902 near the first drill rod 2 is in close contact with the surface of the first drill rod 2.

[0033] In this embodiment: the positioning ring 301 is quickly locked and released by the cooperation of the threaded post 901, the anti-slip pad 902 and the limiting block 903. When the threaded post 901 is rotated, the anti-slip pad 902 can press the surface of the first drill rod 2, and the elastic deformation of the rubber material generates friction to ensure that the positioning ring 301 does not slip during drilling.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the front and rear sides of the first drill rod 2 are provided with grooves 8, and the slider 303 is slidably connected inside the grooves 8.

[0035] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, the bottom of the positioning ring 301 is fixedly connected to the scraper ring 5, the surface of the scraper ring 5 is in movable contact with the surface of the first drill rod 2, and the bottom of the scraper ring 5 is chamfered.

[0036] In this embodiment: the sliding groove 8 on the surface of the first drill rod 2 and the sliding block 303 inside the positioning ring 301 provide a precise moving track for the positioning ring 301, ensuring that it is smoothly adjusted along the axis of the first drill rod 2. The scraper ring 5 at the bottom of the positioning ring 301, through the chamfer design, can efficiently scrape away the mud and impurities adhering to the surface of the first drill rod 2 during the movement of the positioning ring 301, reducing the moving resistance of the positioning ring 301. The linkage design between the scraper ring 5 and the sliding groove 8 prevents the positioning ring 301 from contacting and getting stuck with the mud when sliding up and down.

[0037] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, the surface of the scraper block 302 is in active contact with the inner wall of the slide groove 8. Both the scraper block 302 and the scraper ring 5 are made of white cast iron.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the bottom of the first drill rod 2 and the second drill rod 4 are both fixedly connected with threaded sleeves 7, and the top of the inner wall of the second drill rod 4 is provided with a threaded groove 12, and the threaded sleeve 7 is threadedly connected to the threaded groove 12.

[0039] In this embodiment: the scraper block 302 and the scraper ring 5 are made of white cast iron. Utilizing its high hardness and wear-resistant properties, they can withstand long-term, high-frequency soil scraping, thus extending their service life. The first drill rod 2 and the second drill rod 4 are connected by the threaded sleeve 7 and the threaded groove 12 to form a standardized interface, which supports quick disassembly and assembly and the combination of multiple second drill rods 4. The total length of the second drill rod 4 can be flexibly adjusted according to the drilling depth.

[0040] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, a raised ring 10 is fixedly connected to the top of the second drill rod 4, and a rubber sealing gasket 11 is fixedly connected to the top of the raised ring 10. A slot 13 is opened at the bottom of the first drill rod 2. The raised ring 10 is movably inserted into the inside of the slot 13, and the top of the rubber sealing gasket 11 is in close contact with the inner wall of the slot 13.

[0041] Specifically, such as Figure 2 As shown, the positioning ring 301 is made of stainless steel.

[0042] In this embodiment: the protruding ring 10 at the top of the second drill rod 4 and the slot 13 at the bottom of the first drill rod 2 are inserted and fitted together, and together with the rubber sealing gasket 11, a double leak-proof structure is formed, which effectively isolates the mud from the strata at different depths from the sample when the first drill rod 2 and the second drill rod 4 are pulled up. The positioning ring 301 is made of stainless steel, which is corrosion-resistant and rust-proof, and extends its service life.

[0043] Working principle: When the first drill rod 2 is connected to several second drill rods 4 through the threaded sleeve 7 and threaded groove 12, if there is a deviation between the total length and the drilling depth required for geological exploration, the positioning ring 301 can be adjusted by observing the scale line 6 on the surface of the first drill rod 2 and sliding it up and down along the slide groove 8. The slider 303 on the inner wall of the positioning ring 301 drives the scraper 302 to move synchronously. The triangular scraper 302 scrapes away the soil in the slide groove 8, and the scraper ring 5 scrapes away the soil on the surface of the first drill rod 2, ensuring that the positioning ring 301 slides smoothly. After adjusting to the target position, the threaded column 901 of the limiting mechanism 9 is rotated to make the anti-slip rubber pad 902 press against the surface of the first drill rod 2, locking the position through friction. At this time, the total length of the second drill rod 4 plus the distance from the bottom of the first drill rod 2 to the bottom of the positioning ring 301 is the set drilling depth. During the process of the backpack-type geological drilling rig body 1 driving the first drill rod 2 and the second drill rod 4 to drill into the strata, when the bottom of the positioning ring 301 contacts the ground, it indicates that the preset depth has been reached, and the drilling should be stopped immediately. Drilling achieves precise control of drilling depth. Simultaneously, the raised ring 10 at the top of the second drill rod 4 engages with the slot 13 at the bottom of the first drill rod 2. A rubber sealing gasket 11 prevents mud at different depths from seeping into the interior of the first and second drill rods 2 and 4 through the threaded sleeve 7 and threaded groove 12 when the first and second drill rods 2 and 4 are pulled out, thus preventing it from contacting the sample and affecting the accuracy of the drilling sample. The white cast iron scraper 302 and scraper ring 5 ensure wear resistance, while the stainless steel positioning ring 301 enhances corrosion resistance and extends service life. This solves the problem in existing patents where the lengths of the sampling pipes A and B are too long, and when connected, they cannot precisely match the required sampling depth for geological exploration, thus hindering precise control of the sampling depth and affecting the accuracy of the geological exploration results. It should be noted that the backpack-type geological drilling rig body 1 is a mature technology already published, and its basic mechanism will not be elaborated here.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
