Description

Technical Field

[0001] This invention relates to the field of exploration equipment, and more particularly to a circumferential rock magnetic exploration device. Background Technology

[0002] A rock magnetic exploration device is a tool used to measure the magnetic characteristics of underground rocks. It primarily obtains information about geological structure and mineral resources by measuring the magnetic field of underground rocks.

[0003] Existing magnetic rock exploration involves placing the rock on a testing platform and then using a magnetic probe to measure the rock according to a predetermined path or arrangement. However, since the magnetic probe is moved manually, it is easy for it to deviate from the predetermined path, affecting the accuracy of the magnetic rock exploration.

[0004] Therefore, a circular rock magnetic exploration device has now been developed that enables the magnetic probe to move along a circular track, preventing the magnetic probe from deviating from the circular path and improving exploration accuracy. Summary of the Invention

[0005] To overcome the shortcomings of existing rock magnetic exploration methods, which rely on manual movement of the magnetic probe, which can easily cause the probe to deviate from its intended path and affect the accuracy of the rock magnetic exploration, this invention provides a circular rock magnetic exploration device that allows the magnetic probe to move along a circular track, preventing it from deviating from the circular path and improving exploration accuracy.

[0006] The technical implementation of the present invention is as follows: a circumferential rock magnetic exploration device, comprising a tailstock, an I-shaped ridge, support legs, a spool, a torsion spring, a rope, a front arc, a rotating fan mechanism, and a lateral displacement mechanism. The upper part of the tailstock is connected to the I-shaped ridge, and the front and rear parts of the I-shaped ridge are each connected to two support legs. A spool is rotatably connected to each support leg. A torsion spring is connected between each spool and the adjacent support leg. A rope is wound around each spool. The rear side of the I-shaped ridge is connected to the front arc. A rotating fan mechanism capable of rotation is provided on the I-shaped ridge, and a lateral displacement mechanism capable of lateral displacement is provided on the rotating fan mechanism.

[0007] Optionally, the rotating fan mechanism includes a fan-shaped frame, a sweeping rail, an instrument cover, a magnetic prospector, and a probe head. Both sides of the I-beam ridge are slidably connected to fan-shaped frames, and the ropes are connected to adjacent fan-shaped frames. A sweeping rail is slidably connected to the right fan-shaped frame, and the sweeping rail can slide onto the left fan-shaped frame. An instrument cover is slidably connected to the sweeping rail, and a magnetic prospector is snapped onto the instrument cover. A probe head is connected to the rear of the magnetic prospector, and the probe head contacts the sweeping rail, engaging the magnetic prospector with the instrument cover. Then, according to the rock exploration requirements, the sweeping rail moves on the fan-shaped frame, driving the magnetic prospector to move, allowing the probe head to explore the rock.

[0008] Optionally, the lateral shifting mechanism includes a motor, a main shifting gear, a rack, a secondary shifting gear, and a first belt. The motor is connected to the front of the sweeping rail, and the main shifting gear is connected to the output shaft of the motor. Racks are connected to both the front and rear of the sector frame. The secondary shifting gear is rotatably connected to the rear of the sweeping rail. The rear racks mesh with the secondary shifting gears, and the front racks mesh with the main shifting gears. The main shifting gear and the secondary shifting gear are connected by a first belt through a pulley. When the motor is started, the main shifting gear is driven to rotate, causing the main shifting gear to mesh with the rack.

[0009] Optionally, it also includes a fixing mechanism, which includes an arc clamp, peripheral teeth and a return spring. The arc clamp is slidably connected to the front of the I-beam ridge, and peripheral teeth are connected to the front of the fan-shaped frame. The peripheral teeth are engaged with the arc clamp. A return spring is connected between the I-beam ridge and the arc clamp. When it is necessary to move the fan-shaped frames away from each other, the arc clamp is pulled forward, and the return spring contracts, causing the arc clamp to disengage from the peripheral teeth.

[0010] Optionally, it also includes a handle, with a handle connected to the front side of the middle of the arc clamp plate.

[0011] Optionally, it also includes a continuing mechanism, which includes a compression spring, a pressing bar, a fixed column, a mounting column, an external moving gear, an angle end gear, a lower housing, a second belt, and a starting pulley. The pressing bars are slidably connected to the upper front of the sector frame, and each pressing bar is connected to a compression spring via a pressing spring. The pressing bars are in contact with each other. Multiple fixed columns are connected to the front of each sector frame, and the pressing bars are in contact with these fixed columns. A mounting column is connected to the upper middle of the arc clamp plate. An external moving gear is connected to the upper part of the motor output shaft. The tailstock has two sections on the left and right sides. The upper side is connected to the lower shell. The lower shells on opposite sides are rotatably connected to corner gears. The lower shells on opposite sides are rotatably connected to starting wheels. The starting wheels mesh with the adjacent peripheral teeth. The starting wheels and the adjacent corner gears are connected by a second belt through a pulley. When the sweeping rail moves to the outermost end of the fan-shaped frame, the main moving gear pushes the extrusion bar to move. The fixed column limits the extrusion bar. The compression spring contracts, causing the extrusion bar to press the mounting column forward, which in turn moves the arc clamp forward and disengages from the peripheral teeth.

[0012] Optionally, it also includes a flushing mechanism, which includes a mounting base, a water pipe and a nozzle. Multiple mounting bases are connected to the upper side of the fan-shaped frame, and water pipes are connected between adjacent mounting bases. A nozzle is connected to the rear side of each water pipe. The water pipe is fixed by the mounting base, and water is then supplied to the water pipe so that water is sprayed from the nozzle onto the rock.

[0013] Optionally, it also includes a sample placement mechanism, which includes a half-disc and a central rotating disk. The half-disc is connected to the front side of the middle of the front arc, and the central rotating disk is rotatably connected to the half-disc. The rock sample is placed on the central rotating disk of the half-disc, and the angle of the central rotating disk is adjusted according to the rock sample detection needs.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention connects the magnetic probe with the instrument cover, and then moves the sweeping rail on the fan-shaped frame according to the rock exploration requirements, thereby moving the magnetic probe and enabling the probe head to explore the rock. This achieves the effect of enabling the magnetic probe to move along the circular track, avoiding the magnetic probe from deviating from the circular path, and improving the exploration accuracy.

[0015] 2. This invention starts a motor, which drives the main shift gear to rotate, causing the main shift gear to mesh with the rack. At the same time the main shift gear rotates, the secondary shift gear rotates through the first belt drive. The secondary shift gear meshes with the rack, causing the sweeping rail to slide on the sector frame. This achieves the effect of enabling the sweeping rail to move automatically, saving manpower and improving detection efficiency.

[0016] 3. This invention moves the arc clamp forward, causing the return spring to contract and disengage the arc clamp from the outer teeth. After the sector frame is adjusted, the return spring rebounds, causing the arc clamp to reset and re-engage with the outer teeth. This achieves the effect of fixing the sector frame and preventing its movement from affecting the magnetic prospector's detection path.

[0017] 4. The present invention drives the outer gear to rotate on the lower housing by meshing with the corner gear. Then, through the second belt drive, the starting wheel rotates and meshes with the outer gear, thus enabling the sector frame to move outward, which facilitates the expansion of the magnetic prospector's detection path.

[0018] 5. This invention fixes the water pipe with a mounting base and then flows water into the water pipe so that the water is sprayed from the nozzle onto the rock, thereby achieving the effect of washing the rock surface and avoiding the impact of impurities on the rock surface on the detection accuracy.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0033] A type of encircling rock magnetic exploration device, such as Figure 1 , Figure 2 , Figure 3 and Figure 12As shown, it includes a tailstock 1, an I-shaped ridge 2, support legs 3, a spool 30, a torsion spring 301, a rope 302, a front arc 4, a rotating fan mechanism 5, and a side-shifting mechanism 6. The tailstock 1 is connected to the upper part of the I-shaped ridge 2. The front and rear parts of the I-shaped ridge 2 are connected to two left and right support legs 3. The support legs 3 are rotatably connected to the spools 3. The spools 30 are connected to the adjacent support legs 3 by torsion springs 301. The ropes 302 are wound around the spools 30. The front arc 4 is connected to the rear side of the I-shaped ridge 2. The I-shaped ridge 2 is equipped with a rotating fan mechanism 5. The rotating fan mechanism 5 is equipped with a side-shifting mechanism 6.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the rotating fan mechanism 5 includes a fan-shaped frame 51, a sweeping rail 52, an instrument cover 53, a magnetic prospector 54, and a probe head 55. The fan-shaped frame 51 is slidably connected to both the left and right sides of the I-beam 2. The rope 302 is connected to the adjacent fan-shaped frame 51. The sweeping rail 52 is slidably connected to the right fan-shaped frame 51. The sweeping rail 52 can slide onto the left fan-shaped frame 51. The instrument cover 53 is slidably connected to the sweeping rail 52. The magnetic prospector 54 is snapped onto the instrument cover 53. The probe head 55 is connected to the rear side of the magnetic prospector 54. The probe head 55 is in contact with the sweeping rail 52.

[0035] When using this invention, the tailstock 1 is first placed in the rock magnetic exploration area, and the I-shaped ridge 2 is supported by the support leg 3. Then, the rock is placed at the center of the front arc 4, and the magnetic probe 54 is engaged with the instrument cover 53. Then, according to the rock exploration requirements, the sweeping rail 52 is moved on the fan-shaped frame 51, which drives the magnetic probe 54 to move, so that the probe head 55 can explore the rock. This allows the magnetic probe 54 to move along the circular track, preventing the magnetic probe 54 from deviating from the circular path and improving the exploration accuracy. When it is necessary to expand the movement path, the fan-shaped frames 51 can be slid away from each other, which drives the rope 302 to extend, causing the spool 30 to rotate and the torsion spring 301 to deform, so that the sweeping rail 52 slides on one of the fan-shaped frames 51, so as to expand the movement path of the magnetic probe 54.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, the lateral shifting mechanism 6 includes a motor 61, a main shifting gear 62, a rack 63, a secondary shifting gear 64, and a first belt 65. The front part of the sweeping rail 52 is connected to the motor 61, and the output shaft of the motor 61 is connected to the main shifting gear 62. The front and rear parts of the sector frame 51 are both connected to racks 63. The rear part of the sweeping rail 52 is rotatably connected to the secondary shifting gear 64. The rear racks 63 are all meshed with the secondary shifting gear 64, and the front racks 63 are all meshed with the main shifting gear 62. The main shifting gear 62 and the secondary shifting gear 64 are connected by a first belt 65 through a pulley.

[0037] Using the lateral shift mechanism 6 of this device, the scanning rail 52 can be moved. The motor 61 is started, which drives the main shift gear 62 to rotate, so that the main shift gear 62 meshes with the rack 63. At the same time as the main shift gear 62 rotates, the secondary shift gear 64 is rotated through the first belt 65. The secondary shift gear 64 meshes with the rack 63, so that the scanning rail 52 slides on the sector frame 51. This enables the scanning rail 52 to move automatically, saves manpower, and improves detection efficiency.

[0038] like Figure 1 , Figure 4 , Figure 5 and Figure 11 As shown, it also includes a fixing mechanism 7, which includes an arc clamp 71, peripheral teeth 72, a handle 73, and a return spring 74. The arc clamp 71 is slidably connected to the front of the I-shaped ridge 2, and peripheral teeth 72 are connected to the front of the fan-shaped frame 51. The peripheral teeth 72 are engaged with the arc clamp 71. The handle 73 is connected to the front of the middle part of the arc clamp 71, and a return spring 74 is connected between the I-shaped ridge 2 and the arc clamp 71.

[0039] Using the fixing mechanism 7 of this device, the sector frame 51 can be fixed. When it is necessary to move the sector frames 51 away from each other, the handle 73 is used to pull the arc clamp 71 forward, the return spring 74 contracts, and the arc clamp 71 disengages from the outer teeth 72. After the sector frame 51 is adjusted, the return spring 74 rebounds, driving the arc clamp 71 to reset, so that the arc clamp 71 and the outer teeth 72 re-engage, thereby fixing the sector frame 51 and preventing the movement of the sector frame 51 from affecting the detection path of the magnetic prospector 54. When the sector frame 51 needs to be reset, the arc clamp 71 is disengaged from the outer teeth 72, the torsion spring 301 returns to its original state, and the rope 302 is pulled back, so that the sector frame 51 is reset.

[0040] like Figure 1 , Figure 8 , Figure 9 and Figure 11As shown, it also includes a continuing mechanism 8, which includes a compression spring 81, an extrusion bar 82, a fixed post 83, a mounting post 84, an external gear 85, a corner gear 86, a lower housing 87, a second belt 88, and a starting wheel 89. Extrusion bars 82 are slidably connected to the upper front part of each sector frame 51. Each extrusion bar 82 is connected to a compression spring 81, and the extrusion bars 82 are in contact with each other. Six fixed posts 83 are connected to the front part of each sector frame 51, and the extrusion bars 82 are all connected to the fixed posts 84. The fixed column 83 is in contact with the upper part of the arc clamp 71 and the mounting column 84 is connected to the middle. The upper part of the output shaft of the motor 61 is connected to the external moving gear 85. The upper parts of the left and right sides of the tailstock 1 are both connected to the lower housing 87. The lower housing 87 is rotatably connected to the side that is far apart from each other. The lower housing 87 is rotatably connected to the side that is close to each other. The starting wheel 89 is meshed with the adjacent peripheral gear 72. The starting wheel 89 and the adjacent corner gear 86 are connected by a second belt 88 through a pulley.

[0041] Using the continuation mechanism 8 of this device, the sector frame 51 can be moved outward. When the sweeping rail 52 moves to the outermost end of the sector frame 51, the main moving gear 62 pushes the extrusion bar 82 to move. The fixed column 83 limits the extrusion bar 82, and the compression spring 81 contracts, causing the extrusion bar 82 to press the mounting column 84 forward, driving the arc clamp 71 to move forward and disengage from the outer gear 72. This causes the outer moving gear 85 to mesh with the corner gear 86, driving the corner gear 86 to rotate on the lower housing 87. Then, through the second belt 88, the starting wheel 89 rotates and meshes with the outer gear 72, pushing the sector frame 51 outward. This allows the sector frame 51 to move outward, facilitating the expansion of the magnetic prospector 54's detection path.

[0042] like Figure 1 and Figure 10 As shown, it also includes a rinsing mechanism 9, which includes a mounting base 91, a water pipe 92 and a nozzle 93. Seven mounting bases 91 are connected to the upper side of the fan-shaped frame 51, and water pipes 92 are connected between adjacent mounting bases 91. A nozzle 93 is connected to the rear side of each water pipe 92.

[0043] Using the flushing mechanism 9 of this device, the rock can be flushed. The water pipe 92 is fixed by the mounting base 91, and water is then passed into the water pipe 92 so that the water is sprayed from the nozzle 93 onto the rock, thereby flushing the rock surface and preventing impurities on the rock surface from affecting the accuracy of the detection.

[0044] like Figure 1 and Figure 10 As shown, it also includes a sample placement mechanism 10, which includes a half-plate 101 and a central rotary disk 102. The half-plate 101 is connected to the front side of the middle of the front arc 4, and the central rotary disk 102 is rotatably connected to the half-plate 101.

[0045] Using the sample placement mechanism 10 of this device, rock samples can be placed on the central rotating disk 102 of the half-receiving disk 101. Then, according to the needs of rock sample detection, the angle of the central rotating disk 102 can be adjusted by rotating it, thereby enabling the rock sample to be placed at the center of the front arc 4 and avoiding the positional deviation of the rock sample.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
