Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, in particular to a groove sampling equipment for geological and mineral exploration. Background Art

[0002] Grooving is a commonly used sampling method in the field of geological exploration. Generally, a regular long groove of corresponding size is chiseled on the surface of the ore body along its thickness direction, and the chiseled fragments are the samples obtained.

[0003] The traditional grooving method is generally done manually by relevant personnel, which is time-consuming and labor-intensive. Nowadays, grooving sampling can be carried out with the assistance of tools, which is more convenient and more efficient. For example, a sampling device for geological exploration and mapping based on the grooving method is disclosed in the prior art with publication number CN217930903U.

[0004] The sampling device in the prior art generally needs to use two cutting wheels to open two narrow slits on the ore body according to the set width, and then take out the ore body between the two narrow slits as a sample. The internal space of the sampling slot opened by this grooving method is narrow and the connection between the sample and the ore body is tight, so sampling is inconvenient. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a groove sampling device for geological and mineral exploration to solve the problem of inconvenience in sampling caused by narrow internal space of the sampling groove and tight connection between the sample and the ore body in the prior art.

[0006] The present invention is achieved through the following technical solutions:

[0007] A notching sampling device for geological and mineral exploration comprises a motor box, a fixed arm is fixedly arranged on the front side of the motor box, a cutting assembly is arranged on one side of the fixed arm, a driving motor for driving the cutting assembly is fixedly arranged on the inner wall of the motor box, and the driving motor and the fixed arm are connected by a belt structure;

[0008] The cutting assembly includes a fixed shaft rotatably connected to the fixed arm, the cross section of the fixed shaft is rectangular, and a plurality of transversely arranged cutting wheels are sleeved on the outer end of the fixed shaft, so that the cutting wheel sleeved on the outer end thereof can be driven to rotate by the rotation of the fixed shaft, and a pad is provided between two adjacent cutting wheels, the pad is sleeved on the outer end of the fixed shaft, and the diameter of the pad is smaller than the diameter of the cutting wheel. After the cutting wheel rotates, it contacts the surface of the ore body and cuts it. Since there are a plurality of cutting wheels on the outer end of the fixed shaft, a plurality of narrow grooves will be cut on the surface of the ore body, and the two outermost narrow grooves are the boundaries of the sampling groove;

[0009] Two grinding wheels are provided on the outer end of the fixed shaft, and the outer ends of the grinding wheels are inclined surfaces. All the cutting wheels are located between the two grinding wheels. The two grinding wheels are respectively fitted with the two outermost cutting wheels, and the grinding wheels are in the shape of a truncated cone. As the cutting deepens, the outer ends of the two grinding wheels will contact the two boundaries of the sampling groove, and the inner walls of the two sides of the sampling groove that were originally perpendicular to the ore body will be ground into a slope shape, making the opening of the sampling groove wider.

[0010] Furthermore, a limiting plate is fixedly provided on the outer end of the fixed shaft, a pressing plate is sleeved on the outer end of the fixed shaft, and two grinding wheels are located between the pressing plate and the limiting plate and are respectively fitted with the pressing plate and the limiting plate;

[0011] An end plate is provided at one end of the fixed shaft away from the fixed arm through bolts, and a plurality of bolts for fixing the pressure plate are provided on the end plate through threads. After the bolts are tightened, one end of the bolts rests on the pressure plate, thereby applying pressure to the pressure plate, thereby clamping and fixing the cutting wheel, pad and grinding wheel. All the cutting wheels, pads and grinding wheels are clamped between the pressure plate and the limit plate. According to different sampling requirements, the number of cutting wheels and pads can be adjusted automatically.

[0012] Furthermore, a removable cover is provided at one end of the motor box away from the fixed arm, and a heat dissipation net is embedded in the end of the motor box facing the fixed arm, so that the drive motor is enclosed inside the motor box and heat dissipation is facilitated. The motor box protects the drive motor and increases the service life of the drive motor.

[0013] Furthermore, a handle is fixedly provided on the top of the motor box, and a plurality of buttons for controlling the driving motor are fixedly provided on the outer end of the handle, so that the motor can be conveniently controlled while being held in the hand.

[0014] Furthermore, a dust cover is provided above the cutting assembly, and one end of the dust cover is detachably connected to the fixed arm to shield the fragments flying during the cutting process so that they will not fly toward the operator and cause unnecessary harm. A plurality of atomizing nozzles penetrating the dust cover are fixed on the dust cover to spray cooling water to the cutting assembly and suppress dust.

[0015] Furthermore, a dust suction assembly is provided at one end of the cover plate away from the fixed arm, and the dust suction assembly includes a detachable collecting tube arranged on the cover plate, an air inlet channel is fixedly provided at the outer end of the collecting tube, and an air inlet hole is opened on the side of the air inlet channel facing the cutting assembly, and dust and air are sucked into the air inlet channel together through the air inlet hole.

[0016] Furthermore, a removable filter is provided on the inner wall of the collecting cylinder, and a fan for driving air flow is fixedly provided at one end of the collecting cylinder away from the motor box. The fan drives the air flow and discharges the air in the collecting cylinder, thereby generating negative pressure inside the collecting cylinder and thereby generating suction.

[0017] Furthermore, a bracket is fixedly provided on the rear side of the motor box, and a positioning plate is provided on the rear side of the bracket through a ball hinge. Under the connecting action of the ball hinge, the motor box can rotate in all directions relative to the positioning plate without affecting the flexibility during the sampling process. Straps are fixedly provided at both ends of the positioning plate, and the positioning plate can be tied to the waist of the operator through the straps. In this way, part of the weight of the sampling equipment is borne by the torso of the operator, and the weight borne by the arms is greatly reduced.

[0018] The beneficial effects of the present invention are:

[0019] 1. The notching sampling equipment for geological and mineral exploration has multiple cutting wheels at the outer end of the fixed shaft. The cutting wheels cut on the surface of the ore body to divide the sample into multiple strips. The connection between each independent sample and the ore body is thin and the strength of the connection is low, which is convenient for separation between the sample and the ore body.

[0020] 2. By providing grinding wheels on the two outermost cutting wheels, the outer ends of the two grinding wheels will contact the two boundaries of the sampling groove, and the inner walls of the two sides of the sampling groove that are originally perpendicular to the ore body will be ground into a slope shape, making the opening of the sampling groove wider, facilitating the operation of separating samples and making sampling more convenient.

[0021] 3. The positioning plate is bound to the operator's body by straps, and the motor box is connected to the front side of the positioning plate, so that part of the weight of the sampling device is borne by the operator's torso, and the weight borne by the arm is greatly reduced, which reduces the burden on the operator and the difficulty of operation.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0038] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0039] See also Figure 1-10 The present invention provides a technical solution: a groove sampling device for geological and mineral exploration, comprising a motor box 1, a fixed arm 9 is fixedly provided on the front side of the motor box 1, a cutting assembly 3 is provided on one side of the fixed arm 9, a driving motor 12 for driving the cutting assembly 3 is fixedly provided on the inner wall of the motor box 1, the driving motor 12 and the fixed arm 9 are connected by a belt structure transmission, and the model of the driving motor 12 is HPE50LB2;

[0040] The cutting assembly 3 includes a fixed shaft 301 rotatably connected to the fixed arm 9, the cross section of the fixed shaft 301 is rectangular, the outer end of the fixed shaft 301 is sleeved with a plurality of transversely arranged cutting wheels 304, a pad 305 is provided between two adjacent cutting wheels 304, the pad 305 is sleeved on the outer end of the fixed shaft 301, and the diameter of the pad 305 is smaller than the diameter of the cutting wheel 304;

[0041] Two grinding wheels 306 are sleeved on the outer end of the fixed shaft 301 . The outer ends of the grinding wheels 306 are inclined surfaces. All the cutting wheels 304 are located between the two grinding wheels 306 . The two grinding wheels 306 are respectively fitted with the two outermost cutting wheels 304 .

[0042] The fixed shaft 301 is driven to rotate by the driving motor 12 inside the motor box 1. The cross section of the fixed shaft 301 is rectangular. Therefore, the rotation of the fixed shaft 301 can drive the cutting wheel 304 sleeved on the outer end thereof to rotate. After the cutting wheel 304 rotates, it contacts the surface of the ore body 15 to cut it. Since there are multiple cutting wheels 304 at the outer end of the fixed shaft 301, multiple narrow grooves will be cut on the surface of the ore body 15. The space between two adjacent narrow grooves is the sample 16. Therefore, the narrow grooves divide multiple samples 16 on the ore body 15. The two outermost narrow grooves are the boundaries of the sampling groove 17.

[0043] While cutting, the two outermost cutting wheels 304 are also provided with grinding wheels 306, which are in the shape of a truncated cone. As the cutting progresses, the outer ends of the two grinding wheels 306 will contact the two boundaries of the sampling groove 17. The grinding wheels 306 rotate at high speed, which plays a grinding role, and grinds the inner walls of the two sides of the sampling groove 17 that are originally perpendicular to the ore body 15 into a slope shape, so that the opening of the sampling groove 17 is wider. After the grooving is completed, the sample 16 is cut from the root of each sample 16 and the ore body 15, and the sample 16 can be taken out;

[0044] The cutting component 3 can be used to divide the sample 16 into multiple strips. The connection between each independent sample 16 and the ore body 15 is thin and the strength of the connection is low, which is convenient for separating the sample 16 from the ore body 15. At the same time, the cross-section of the sampling groove 17 presents an inverted isosceles trapezoid shape, and the internal space of the sampling groove 17 is open, which is convenient for separating the sample 16 and makes sampling more convenient.

[0045] In this embodiment: a limit plate 302 is fixedly disposed at the outer end of the fixed shaft 301, a pressing plate 303 is sleeved at the outer end of the fixed shaft 301, and two grinding wheels 306 are located between the pressing plate 303 and the limit plate 302 and are respectively attached to the pressing plate 303 and the limit plate 302;

[0046] The end of the fixed shaft 301 away from the fixed arm 9 is provided with an end plate 307 through bolts, and the end plate 307 is provided with multiple bolts for fixing the pressure plate 303 through threads. All the cutting wheels 304, pads 305 and grinding wheels 306 are clamped between the pressure plate 303 and the limit plate 302.

[0047] The cutting wheel 304, the pad 305 and the grinding wheel 306 are mounted one by one on the outer end of the fixed shaft 301 according to the arrangement order, regularity and quantity. After the mounting is completed, the pressure plate 303 is mounted on the outermost side of the fixed shaft 301, and the cutting wheel 304, the pad 305 and the grinding wheel 306 are clamped between the limit plate 302 and the pressure plate 303. Then, the end plate 307 is fixed to the end of the fixed shaft 301 away from the fixed arm 9 by bolts, and finally, a plurality of bolts for fixing the pressure plate 303 are installed on the end plate 307. After the bolts are tightened, one end of the bolts abuts against the pressure plate 303, thereby applying pressure to the pressure plate 303, thereby clamping and fixing the cutting wheel 304, the pad 305 and the grinding wheel 306;

[0048] According to different sampling requirements, the number of cutting wheels 304 and pads 305 is adjusted automatically. The more cutting wheels 304 there are, the finer the sample 16 will be divided. At the same time, pads 305 of different thicknesses can be selected according to needs to adjust the distance between two adjacent cutting wheels 304. The thicker the pad 305 is, the thicker the thickness of each sample 16 will be after division. The distance between the two outermost cutting wheels 304 determines the width of the entire sampling slot 17.

[0049] In this embodiment: a detachable cover 13 is provided at one end of the motor box 1 away from the fixed arm 9, and a heat dissipation net 8 is embedded in the end of the motor box 1 facing the fixed arm 9, so as to enclose the drive motor 12 inside the motor box 1 and facilitate heat dissipation.

[0050] The drive motor 12 for driving the cutting assembly 3 to rotate is enclosed inside the motor box 1. The motor box 1 protects the drive motor 12 and increases the service life of the drive motor 12. At the same time, the heat generated during the operation of the drive motor 12 can be dissipated outward through the heat dissipation net 8 under the action of air.

[0051] In this embodiment: a handle 10 is fixedly provided at the top of the motor box 1, and a plurality of buttons for controlling the drive motor 12 are fixedly provided at the outer end of the handle 10, so that control can be performed conveniently during hand-held operation. During the cutting operation, the operator holds the outer end of the handle 10 to control the sampling device, so the button is fixed at the outer end of the handle 10 to facilitate operation of the button while holding the handle 10.

[0052] In this embodiment: a dust cover 2 is provided above the cutting component 3, one end of the dust cover 2 is detachably connected to the fixed arm 9 to shield the fragments flying during the cutting process, and a plurality of atomizing nozzles 14 penetrating the dust cover 2 are fixedly provided on the dust cover 2 to spray cooling water to the cutting component 3 and suppress dust.

[0053] During the cutting process, the ore body 15 will produce powdery or granular fragments due to cutting and grinding. As the cutting assembly 3 rotates, these fragments will splash, and then dust will be dispersed with the airflow. Therefore, a dust cover 2 is arranged above the cutting assembly 3. The dust cover 2 has a blocking effect. Some larger fragments will not splash toward the operator under the blocking of the dust cover 2, and will not cause unnecessary harm.

[0054] At the same time, pure cooling water can be transported to the atomizing nozzle 14 through a pipeline. The cooling water passes through the atomizing nozzle 14 to form water mist that is sprayed toward the cutting component 3. The water mist sprayed toward the cutting component 3 can cool the cutting component 3 during the cutting process. At the same time, the dust generated by the cutting can also be suppressed under the action of the water mist.

[0055] In this embodiment: a dust suction assembly 7 is provided at one end of the cover plate 13 away from the fixed arm 9, and the dust suction assembly 7 includes a detachable collecting cylinder 701 arranged on the cover plate 13, and an air inlet channel 704 is fixedly provided at the outer end of the collecting cylinder 701. The air inlet channel 704 has an air inlet hole on the side facing the cutting assembly 3, and dust and air are sucked into the air inlet channel 704 through the air inlet hole.

[0056] During the cutting process, the air inlet is facing the cutting position. During the cutting process, the cutting fragments generated enter the air inlet channel 704 through the air inlet under the action of the air flow, and then enter the collection tube 701 along the air inlet channel 704, avoiding the dust and fragments generated during the cutting process from splashing around and causing inconvenience.

[0057] In this embodiment: a removable filter 703 is provided on the inner wall of the collecting cylinder 701, and a fan 702 for driving air flow is fixedly provided at the end of the collecting cylinder 701 away from the motor box 1, and the model of the fan 702 is APB25-5-P25KN. The air inlet channel 704 and the fan 702 are respectively located on both sides of the filter 703, and the filter 703 can separate air and solid dust in the air.

[0058] The fan 702 drives the air flow to discharge the air in the collecting tube 701, thereby generating a negative pressure inside the collecting tube 701, and sucking the dust fragments generated during the cutting process into the collecting tube 701. After the mixture of air and dust fragments enters the collecting tube 701, the dust fragments are separated from the air under the action of the filter 703, and the air is finally discharged, and the dust fragments remain on the filter 703 for subsequent cleaning.

[0059] In this embodiment: a bracket 11 is fixedly provided on the rear side of the motor box 1, a positioning plate 4 is provided on the rear side of the bracket 11 through a ball hinge 5, straps 6 are fixedly provided at both ends of the positioning plate 4, and the positioning plate 4 can be tied to the waist of the operator through the straps 6.

[0060] The positioning plate 4 is placed in front of the operator's waist and abdomen, and then the positioning plate 4 is tied to the operator's body through the strap 6. The motor box 1 of the main part of the sampling device is movably connected to the front side of the positioning plate 4 through the ball hinge 5. In this way, part of the weight of the sampling device is borne by the operator's torso, and the weight borne by the arm is greatly reduced, which reduces the burden on the operator and the difficulty of operation. In addition, under the connection of the ball hinge 5, the motor box 1 can rotate in all directions relative to the positioning plate 4 without affecting the flexibility during the sampling process.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
