Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of mineral exploration and material extraction, specifically to an open-pit mine geological exploration device. Background Technology

[0002] In open-pit mining, geological surveying is a crucial step in identifying mineral distribution and assessing resource reserves. The accuracy of the survey data directly impacts mining plan design and resource utilization efficiency. Analysis of strata samples at different depths can effectively determine ore layer thickness, ore grade, and geological structure, providing a scientific basis for safe production and rational resource development. Currently, open-pit geological surveying relies heavily on manual sampling using simple tools such as hammers and chisels. While these tools are easy to operate, they have significant drawbacks in practical application. Due to their fixed length and singular force application, they can only collect surface or shallow soil and rock samples, making it difficult to penetrate hard rock layers or dense soil layers and obtain deep geological samples.

[0003] The lack of deep geological information can lead to incomplete survey data, potentially overlooking hidden mineral layers or misjudging geological structures, increasing the uncertainty of subsequent mining operations. Furthermore, collecting deep samples using simple tools requires repeated manual chiseling, which is not only labor-intensive and inefficient but also prone to safety hazards due to rock fracturing. In addition, manual sampling makes it difficult to guarantee the integrity and representativeness of samples, potentially affecting the reliability of test results and hindering a comprehensive understanding of the open-pit mine's geological conditions.

[0004] Therefore, given the limitations of traditional tools in obtaining deep samples, developing an open-pit mine geological exploration device that can effectively collect geological samples from deeper locations has become an urgent need to improve exploration accuracy and ensure the scientific nature of resource development. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide an open-pit mine geological exploration device, which solves the technical problem in the prior art that, due to the fixed tool length and single force mode, it can only collect rock and soil samples from the surface or shallow layers, and it is difficult to break through the barrier of hard rock layers or dense soil layers, thus making it impossible to obtain deep geological samples.

[0006] According to one aspect, at least one embodiment of this disclosure provides an open-pit mine geological exploration apparatus, comprising:

[0007] A base frame and an upright frame, wherein the upright frame is fixed to the base frame;

[0008] A drilling assembly is mounted on the base frame and the upright frame;

[0009] A support assembly is disposed outside the base frame and the upright frame;

[0010] The drilling assembly includes a top frame mounted on the vertical frame, a drive motor mounted on the top frame, a rotating shaft at the output end of the drive motor, spiral blades on the rotating shaft, and a collection cover on the base frame.

[0011] As a further technical solution, the collecting cover is fitted outside the spiral blade, and a discharge hopper is provided on the top of the collecting cover. One end of the discharge hopper is inclined downward, and a screw is vertically rotatably connected inside the upright frame.

[0012] As a further technical solution, a pair of guide rods are provided inside the upright frame, and the top frame is vertically slidably connected to the guide rods. The top frame and the screw are connected by a threaded connection, and a crank handle is provided at the lower end of the screw.

[0013] As a further technical solution, the support component includes several rectangular openings, all of which are opened on the surface of the base frame. A notch is opened on one side of each rectangular opening, and a flip plate is rotatably connected to the rectangular opening via a pin.

[0014] As a further technical solution, the bottom of the flip plate is provided with several buried poles, and the four corners of the side surface of the upright frame are provided with casters, which are omnidirectional casters that can turn freely.

[0015] As a further technical solution, a conical block is provided at the lower end of the rotating shaft, and the surface of the conical block has a spiral structure.

[0016] As a further technical solution, the maximum rotation angle of the flip plate via the rotation axis is 180°.

[0017] As a further technical solution, a battery pack is installed on the base frame, and the battery pack is linearly connected to the drive motor.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the drilling assembly, through a composite drive design, solves the problem of traditional tools' difficulty in obtaining deep samples. The helical blades and conical block work together to easily penetrate hard rock layers, while the guide rod ensures vertical drilling and avoids deviation. The screw and handle work together to control the drilling depth, and the sample is systematically extracted through the collection hood, ensuring its integrity. This design overcomes shallow-layer limitations, enabling the collection of deep geological samples, improving the comprehensiveness of survey data, while reducing manual labor intensity and adapting to the complex geological environment of open-pit mines.

[0020] 2. In this disclosure, the support components, through a flexible fixing and moving design, solve the problem of poor stability of the device in complex terrain. The flip-up plate drives the buried insertion rod to be quickly anchored, and multi-point support prevents swaying during drilling; the casters enable flexible movement to adapt to the rugged roads of the mining area. The retractable structure combines stability and portability, and can switch modes without additional tools, improving surveying efficiency and ensuring stable operation on soft or sloping ground, thus guaranteeing the accuracy of sample collection.

[0032] like Figs. 1-3 As shown, it illustrates an open-pit mine geological exploration apparatus according to an embodiment of the present disclosure, comprising:

[0033] A base frame 1 and an upright frame 2, wherein the upright frame 2 is fixed on the base frame 1;

[0034] Drilling assembly 3, which is mounted on the base frame 1 and the upright frame 2;

[0035] Support component 4 is disposed outside the base frame 1 and the upright frame 2;

[0036] The drilling assembly 3 includes a top frame 3-1, which is mounted on the vertical frame 2. A drive motor 3-2 is installed on the top frame 3-1, and a rotating shaft 3-3 is provided at the output end of the drive motor 3-2. A spiral blade 3-4 is provided on the rotating shaft 3-3. A collection cover 3-5 is provided on the base frame 1, and the collection cover 3-5 is fitted outside the spiral blade 3-4. A discharge hopper 3-6 is provided on the top of the collection cover 3-5, and one end of the discharge hopper 3-6 is inclined downward. A screw 3-7 is vertically rotatably connected inside the vertical frame 2. A pair of guide rods 3-8 are provided inside the vertical frame 2. The top frame 3-1 is vertically slidably fitted onto the guide rods 3-8. The top frame 3-1 and the screw 3-7 are connected by a threaded connection. A crank handle 3-9 is provided at the lower end of the screw 3-7.

[0037] In some examples, a drilling assembly 3 is designed to achieve deep soil sampling. This assembly includes a top frame 3-1 at the top of a support frame 2, connected to a screw 3-7 via a guide rod 3-8. The guide rod 3-8 is vertically fixed inside the support frame 2. The top frame 3-1 is slidably fitted onto the guide rod 3-8 via a sliding sleeve. The screw 3-7 is vertically rotatably connected inside the support frame 2 via a bearing, engaging with a threaded hole in the top frame 3-1. A crank handle 3-9 at the lower end is fixed with bolts, allowing manual rotation of the screw 3-7. A drive motor 3-2 on the top frame 3-1 is fixed via a flange. The rotating shaft 3-3 at the output end extends vertically downwards, with spiral blades 3-4 welded to the shaft. The blades have sharp edges and can cut through the soil. A collection hood 3-5 on the base frame 1 is fixed via a bracket, is funnel-shaped, and fitted over the spiral blades 3-4. The discharge hopper 3-6 at the top communicates with the collection hood 3-5 and extends downwards at an angle to the outside of the base frame 1.

[0038] During operation, turning the crank handle 3-9 rotates the screw 3-7, which, through a threaded connection, drives the top frame 3-1 to descend vertically along the guide rod 3-8. The drive motor 3-2 drives the rotating shaft 3-3 and the spiral blades 3-4 to rotate at high speed. The spiral blades 3-4 descend with the top frame 3-1, drilling into the soil layer, cutting and conveying deep soil upwards. The soil rises along the spiral surface of the blades, falls into the collection hood 3-5, and slides out through the discharge hopper 3-6, completing the sampling. Reversing the handle, the top frame 3-1 drives the spiral blades 3-4 to rise, detaching from the soil layer. The guide rod 3-8 ensures smooth lifting and lowering of the top frame 3-1, preventing the spiral blades 3-4 from shifting and affecting drilling accuracy. The screw 3-7, in conjunction with the handle, precisely controls the drilling depth. The collection hood 3-5 and discharge hopper 3-6 guide the soil sample out in an orderly manner for easy collection. This component combines spiral drilling with manual lifting to achieve deep soil sampling, offering convenient operation and controllable sampling depth.

[0039] like Figs. 1-3As shown in the figure, the support component 4 in this embodiment includes several rectangular openings 4-1, all of which are opened on the surface of the base frame 1. A notch 4-2 is opened on one side of each rectangular opening 4-1. A flip plate 4-3 is rotatably connected to the rectangular opening 4-1 through a pin. Several buried rods 4-4 are provided at the bottom of the flip plate 4-3. A movable wheel 4-5 is provided at each of the four opposite corners of the side surface of the upright frame 2. The movable wheel 4-5 is a swivel wheel that can turn freely.

[0040] In some examples, to achieve stable support and convenient movement of the device, a support assembly 4 is designed. This assembly includes rectangular openings 4-1 evenly distributed on the surface of the base frame 1, with a rotating plate 4-3 on the inner side connected by a pin, allowing it to be rotated to a vertical position around the pin. A buried insertion rod 4-4 at the bottom is vertically welded with a sharp tip. A notch 4-2 on one side of the rectangular openings 4-1 provides space for the rotating plate 4-3 to rotate. The four corner casters 4-5 on the side surface of the upright frame 2 are fixed by brackets, employing a universal wheel structure with a braking device, allowing for free steering and locking. During the survey, the flip plate 4-3 is flipped from inside the rectangular opening 4-1 to a vertical position, so that the tip of the buried rod 4-4 faces downward. The rod is pressed into the surface soil by external force. The combined action of multiple rods firmly anchors the base frame 1 to the ground, preventing the device from shaking during drilling. When moving, the flip plate 4-3 is flipped back into the rectangular opening 4-1, the rod is retracted, the brake of the moving wheel 4-5 is released, and the device can be moved flexibly by the casters to adjust the survey position.

[0041] The rotating structure of the flip plate 4-3 allows for quick extension and retraction of the insertion rod. The notch 4-2 prevents interference with the base frame 1 during flipping. The multi-point anchoring of the buried insertion rod 4-4 enhances the stability of the device. The free-spinning casters facilitate movement in complex terrain, and the braking device ensures fixation after positioning. This component ensures stability during surveying while improving the device's portability, adapting to the complex environment of open-pit mines. The flexible extension and retraction structure balances stability and portability, allowing for switching between states without additional tools, improving surveying efficiency, ensuring stable operation on soft or sloping ground, and guaranteeing the accuracy of sample collection.

[0042] For example, such as Fig. 2 As shown, a conical block 5 is provided at the lower end of the rotating shaft 3-3, and the surface of the conical block 5 is a spiral structure.

[0043] In some examples, the surface of the conical block 5 at the lower end of the rotating shaft 3-3 has a spiral structure, which helps the rotating shaft 3-3 to drill into hard soil layers more easily. The conical design reduces the resistance to soil penetration, and the spiral structure generates cutting force when it comes into contact with the soil layer. Combined with the rotation of the rotating shaft 3-3, it quickly breaks through the surface hard soil, guides the spiral blades 3-4 smoothly into the deep layers, and improves drilling efficiency, which is especially suitable for the complex geological environment of open-pit mines.

[0044] For example, such asFig. 1 As shown, the maximum rotation angle of the flip plate 4-3 via the rotating shaft 3-3 is 180°.

[0045] In some examples, the flip plate 4-3 can rotate up to 180° via the rotating shaft 3-3, allowing for flexible switching of states. A 180° rotation allows the flip plate 4-3 to change from a horizontal storage state to a vertical working state, enabling the buried insertion rod 4-4 to be inserted vertically into the ground surface, providing stable support; a reverse rotation can retract the insertion rod, fitting it against the base frame 1 without affecting the movement of the device. This large-angle rotation design enhances the practicality of the support assembly 4.

[0046] For example, such as Fig. 1 As shown, a battery pack 6 is mounted on the base frame 1, and the battery pack 6 is linearly connected to the drive motor 3-2.

[0047] In some examples, the battery pack 6 on the base frame 1 is connected to the drive motor 3-2, providing it with power. The battery pack 6 requires no external power source, allowing the device to operate normally in open-pit mines without power supply facilities, enhancing portability. Simultaneously, the stable power output ensures the continuous operation of the drive motor 3-2, guaranteeing stable drilling force of the auger blades 3-4 and improving the continuity of exploration operations.

[0048] In actual use: The pushing device moves the entire unit to the survey point via the moving wheels 4-5, flips the flipping plate 4-3 inside the rectangular opening 4-1 to a vertical position, and inserts the buried rod 4-4 into the ground to fix the base frame 1. The drive motor 3-2 is started, and the rotating shaft 3-3 drives the spiral blades 3-4 and the conical block 5 to rotate. The crank handle 3-9 drives the screw 3-7 to rotate, causing the top frame 3-1 to descend along the guide rod 3-8. The spiral blades 3-4 drill into the soil and transport the sample upwards. The sample is collected by the collection hood 3-5 and discharged into the discharge hopper 3-6. After sampling is completed, the handle 3-9 is cranked in the opposite direction to raise the top frame 3-1, retracting the spiral blades 3-4, resetting the flipping plate 4-3, and the moving wheels 4-5 move the device to the next measurement point. The battery pack 6 provides continuous power to ensure continuous operation.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
