Description

Technical Field

[0001] This application relates to the field of mineral soil sampling technology, and in particular to a detection and sampling device for mining operations. Background Technology

[0002] Ore grade is commonly used to measure the value of ore, but the composition of gangue (useless minerals or minerals with very low content of useful components that cannot be utilized) and the amount of harmful impurities in the same effective ore also affect the ore value. Ore testing includes other metals / semi-metals / non-metals / rare earth elements (grade identification), phase analysis (XRD test), particle size analysis, compressive strength test, and Mohs hardness. Regardless of the type of test, ore sampling is required first.

[0003] One type of sampling device involves first drilling the soil layer at the sampling point using a drill bit, and then using the sampling device to take soil samples.

[0004] However, different drilling tools are required for drilling in different soil layers, and then sampling tools are used to collect samples, which makes the operation cumbersome and time-consuming. Utility Model Content

[0005] To reduce the problems of cumbersome operation and low sampling efficiency during sampling, this application provides a detection and sampling device for mining operations.

[0006] This application provides a detection and sampling device for mining operations, employing the following technical solution:

[0007] A mining detection and sampling device includes a support plate and further includes:

[0008] The motor is fixedly mounted inside the support plate;

[0009] A drilling shaft, the upper end of which is fixedly connected to the output shaft of the motor.

[0010] A transmission shaft, which is rotatably connected to the drilling shaft via a driving component;

[0011] A guide barrel is sleeved on the outer periphery of the conveyor shaft, and the upper end of the guide barrel is fixedly connected to the lower end of the support plate.

[0012] A collection box is fixedly disposed around the guide barrel, and the guide barrel is connected to the conveyor shaft;

[0013] A drill bit, which is detachably connected to the lower end of the drill shaft via a fastener.

[0014] By adopting the above technical solutions, the rotation speed and force of the drill shaft can be precisely controlled by a motor, thereby ensuring the depth and uniformity of sampling during drilling and improving sampling accuracy. Meanwhile, the detachable drill bit design facilitates the replacement of different specifications or types of drill bits to adapt to sampling needs under different geological conditions and different drilling scenarios. The rotatable connection between the conveyor shaft and the drill shaft, as well as the connection between the guide bucket and the conveyor shaft, allows samples obtained during drilling to directly enter the collection bin via the conveyor shaft, eliminating the need for manual collection and thus increasing sampling efficiency.

[0015] Optionally, the driving element includes:

[0016] A gear, which is fixedly disposed on the outer periphery of the drill shaft;

[0017] A rack is circumferentially fixed on the inner circumferential side of the transmission shaft, and the rack meshes with the gear.

[0018] By adopting the above technical solution, the meshing of gears and racks enables the transmission shaft to rotate synchronously when the drilling shaft rotates, thereby ensuring that the sample can smoothly enter the guide bucket and be transported to the collection box through the transmission shaft during the drilling process, thus improving the sampling efficiency.

[0019] Optionally, the drill shaft is an electrically operated telescopic rod.

[0020] By adopting the above technical solution, the drill shaft is an electrically operated telescopic rod, which enables precise control and adjustment of drilling depth, improving the flexibility and adaptability of drilling operations. The use of an electrically operated telescopic rod makes operation more convenient, reduces the time and labor intensity of manual adjustments, and enhances the automation level of the equipment, thereby increasing work efficiency.

[0021] Optionally, the drill bit has a vertically provided limiting groove at its upper end, a horizontally provided mating groove around the limiting groove, a horizontally provided snap-fit ​​groove at the bottom of the mating groove, and a horizontally provided mounting groove at the end of the drill shaft away from the support plate. The fixing component includes:

[0022] A telescopic column, one end of which is fixedly installed at the bottom of the mounting groove;

[0023] A fixing block is fixedly connected to the end of the telescopic column away from the mounting groove;

[0024] An electric control switch is disposed on the upper end of the support plate and is electrically connected to the telescopic column.

[0025] By employing the above technical solution, and through the combined use of the limiting groove, mating groove, and snap-fit ​​groove, the precise positioning and secure installation of the drill bit on the drill shaft can be ensured. The telescopic function of the telescopic column allows the fixing block to easily engage or disengage from the drill bit's snap-fit ​​groove. When it is necessary to replace the drill bit, the drill bit can be quickly disassembled and installed simply by controlling the telescopic column's extension and retraction via an electronic switch.

[0026] Optionally, the conveying shaft is a spiral conveyor shaft.

[0027] By adopting the above technical solution, the spiral conveyor shaft, through its rotational motion, can continuously transport samples obtained during drilling from the drill bit to the collection box. This continuous conveying method avoids sample accumulation and blockage during the transportation process, ensuring smooth sample flow.

[0028] Optionally, a handle is provided at the upper end of the support plate.

[0029] By adopting the above technical solution and designing the handle, operators can more easily hold and control the entire device, improving ease of use and operational stability.

[0030] Optionally, the upper end of the drill bit is provided with a movable groove along the axis, and the lower end of the transmission shaft is rotatably disposed within the movable groove.

[0031] By adopting the above technical solution, a movable groove is axially provided at the upper end of the drill bit, and the lower end of the transmission shaft is rotatably set in the movable groove, which makes the connection between the drill bit and the transmission shaft more stable, and at the same time improves the rotational accuracy and stability of the drill bit, thereby ensuring the smooth progress of the sampling process and improving the quality and efficiency of sample collection.

[0032] In summary, the present invention provides a detection and sampling device for mining operations, which has at least one of the following beneficial technical effects:

[0033] 1. The rotational speed and force of the drill shaft can be precisely controlled by a motor, ensuring the depth and uniformity of sampling during drilling and improving sampling accuracy. Simultaneously, the detachable drill bit design facilitates the replacement of different specifications or types of drill bits to adapt to sampling needs under varying geological conditions and different drilling scenarios. The rotating connection between the conveyor shaft and the drill shaft, as well as the connection between the guide bucket and the conveyor shaft, allows samples obtained during drilling to directly enter the collection bin via the conveyor shaft, eliminating the need for manual collection and thus increasing sampling efficiency.

[0034] 2. The use of limiting grooves, mating grooves, and snap-fit ​​grooves ensures precise positioning and secure installation of the drill bit on the drill shaft. The telescopic function of the telescopic column allows the fixing block to easily engage or disengage from the drill bit's snap-fit ​​groove. When the drill bit needs to be replaced, the telescopic column can be extended or retracted via an electronic switch, enabling quick disassembly and installation of the drill bit.

[0042] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0043] Combination Figure 1 , Figure 2 and Figure 3This application discloses a mining detection and sampling device, including: a support plate 11, and further including: a motor 1, a drilling shaft 12, a conveying shaft 13, a guide barrel 14, a collection box 15, and a drill bit 16. The motor 1 is fixedly installed inside the support plate 11; the upper end of the drilling shaft 12 is fixedly connected to the output shaft of the motor 1, and the conveying shaft 13 is rotatably connected to the drilling shaft 12 through a driving component 2; the guide barrel 14 is sleeved on the outer periphery of the conveying shaft 13, and the upper end of the guide barrel 14 is fixedly connected to the lower end of the support plate 11; the collection box 15 is fixedly installed on the periphery of the guide barrel 14, and the guide barrel 14 is connected to the conveying shaft 13; the drill bit 16 is detachably connected to the lower end of the drilling shaft 12 through a fixing component. The upper end of the drill bit 16 is provided with a moving groove 18, and the lower end of the transmission shaft 13 is rotatably disposed in the moving groove 18. In other words, the moving groove 18 is provided so that when the lengths of the drill shaft 12 and the transmission shaft 13 are the same, the rotation of the drill shaft 12 does not affect the rotation of the transmission shaft 13.

[0044] In this embodiment, the drilling shaft 12 is cylindrical, and both the conveying shaft 13 and the guide barrel 14 are cylindrical. All three are made of rigid materials. The guide barrel 14 and the support plate 11 can be integrally formed or fixedly connected by welding or bolting; this embodiment does not impose specific limitations. The drilling shaft 12 is an electric telescopic rod. The conveying shaft 13 is a spiral conveying shaft. The length of the drilling shaft 12 can be adjusted according to usage requirements. The aggregate is square-shaped, and the aggregate box 15 can be made of rigid material or wood, as long as it can hold soil. The diameter of the drill bit 16 is the same as the diameter of the conveyor pump. It should be noted that there is a gap between the drill bit 16 and the guide barrel 14 for soil transfer. A handle 17 is provided at the upper end of the support plate 11. The handle 17 facilitates the use of the sampling device by personnel.

[0045] In practical use, when only sampling is required, the electric telescopic rod is retracted, meaning the length of the drilling shaft 12 is less than the length of the conveying shaft 13. The conveying shaft 13 and the guide bucket 14 are then inserted into the sampling point. The motor 1 is started, causing the drilling shaft 12 to rotate, which in turn drives the conveying shaft 13 to rotate. This allows the soil to be sampled to enter the conveying shaft 13, and then, based on the rotation of the conveying shaft 13, it is transported to the collection box 15. The guide bucket 14 prevents the soil from falling off during rotation.

[0046] When the soil at the sampling point needs to be drilled, the drill bit is fixed to the drilling shaft 12 through a fixing member, so that the detection and sampling device can drill and sample at the same time. In specific use, the electric telescopic rod is extended, that is, the length of the electric telescopic rod is greater than the length of the transmission shaft 13. The drill bit 16 is fixed to the end of the electric telescopic rod away from the motor 1 through the fixing member. Then the drill bit 16 is inserted into the sampling point, the motor 1 is started, so that the drilling shaft 12 rotates, which drives the drill bit 16 to rotate, thereby breaking the soil layer. The broken soil layer can be transported to the collection box 15 under the rotation of the transmission shaft 13, which is simple and convenient.

[0047] Combination Figure 3 Specifically, the drive component 2 includes a gear 21 and a rack 22. The gear 21 is fixedly disposed on the outer periphery of the drilling shaft 12; the rack 22 is circumferentially fixedly disposed on the inner periphery of the transmission shaft 13, and the rack 22 meshes with the gear 21.

[0048] In this embodiment, both gear 21 and rack 22 are arranged in a ring shape. The inner circumference of gear 21 is fixed to the circumference of drilling shaft 12, and the outer circumference of rack 22 is fixed to the inner circumference of conveying shaft 13. The fixing method can be integral molding, welding, or bolting. In actual use, after starting motor 1, motor 1 drives drilling shaft 12 to rotate. As drilling shaft 12 rotates, it causes the output wheel to rotate. Since rack 22 meshes with rack 22, when drilling shaft 12 drives gear 21 to rotate, gear 21 drives rack 22 to rotate, which in turn drives conveying shaft 13 to rotate, transporting the soil to collection box 15 via conveying shaft 13.

[0049] Combination Figure 4 and Figure 5 More specifically, the upper end of the drill bit 16 is vertically provided with a limiting groove 34, the periphery of the limiting groove 34 is horizontally provided with a mating groove 35, the bottom of the mating groove 35 is horizontally provided with a snap-fit ​​groove 36, the end of the drill shaft 12 away from the support plate 11 is horizontally provided with an installation groove 37, and the fixing components include a telescopic column 31, a fixing block 32, and an electric control switch 33. One end of the telescopic column 31 is fixedly provided at the bottom of the installation groove 37; the fixing block 32 is fixedly connected to the end of the telescopic column 31 away from the installation groove 37; the electric control switch 33 is provided at the upper end of the support plate 11 and is electrically connected to the telescopic column 31.

[0050] In this embodiment, the telescopic column 31 is cylindrical, the fixing block 32 is square, the limiting groove 34 is disc-shaped, the mating groove 35 is arc-shaped, and the snap-fit ​​groove 36 is located at the end of the mating groove 35 away from the through hole. The snap-fit ​​groove 36 and the mounting groove 37 have the same specifications and are used so that when the snap-fit ​​groove 36 is connected to the mounting groove 37, the fixing block 32 is embedded in the snap-fit ​​groove 36.

[0051] In practical use, when drilling is required, the electric control switch 33 is controlled to shorten the telescopic column 31 so that the fixing block 32 is in the mounting groove 37, and the drilling shaft 12 is placed in the limiting groove 34. The electric control switch 33 is then controlled to extend the telescopic column 31 so that the fixing block 32 is placed in the mating groove 35. Then, the drill bit 16 is rotated so that the side wall of the fixing block 32 abuts against the end of the mating groove 35 away from the through hole, so that the snap-fit ​​groove 36 is connected to the mounting groove 37. Then, the electric control switch 33 is controlled to extend the telescopic column 31, pushing the fixing block 32 to slide in the mounting groove 37, and embedding the fixing block 32 in the snap-fit ​​groove 36, thereby fixing the drill bit 16 and the drilling shaft 12.

[0052] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
