Description

Technical Field

[0001] The present invention relates to the technical field of exploration devices, and in particular to a distributed exploration device for geological and mineral resources. Background Art

[0002] Mineral resources are a collection of minerals and useful elements buried underground, formed by geological mineralization, and with utilization value. They include oil, coal, metals, limestone, etc. Mineral resources are an important material basis for the survival and development of human society, and are also an important guarantee for national security and economic development.

[0003] Mastering the real and accurate basic data of mineral resources can provide an important basis for formulating national resource strategies, plans and policies, thereby ensuring the country's economic security and sustainable development. However, most mineral resources are hidden deep underground and require the help of equipment for detailed exploration, such as a distributed exploration device for geological mineral resources with a publication number of CN218956154U in the prior art.

[0004] The core component of the exploration device in the prior art is the drill bit, which is used to drill holes and take samples of the soil and rock layers below the ground. During the drilling process, the motor drives the drill bit to rotate at high speed, and the operator needs to hold the handle to fix the motor. If the motor is not fixed, the drill bit will not move while the motor rotates by itself. Therefore, the operator needs to use his own strength to resist the resistance of the drill bit during rotation while holding the handle with both hands, which is very laborious.

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

[0037] 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.

[0038] See also Figure 1-10 The present invention provides a technical solution: a distributed exploration device for geological mineral resources, comprising a drill bit 5, a driving motor 10 capable of driving the drill bit 5 to rotate is provided on the top of the drill bit 5, the model of the driving motor 10 is YB2-132S-4H, the rated power of the motor is 540W, the rated voltage is 660V, the rated current is 360A, and it is an explosion-proof asynchronous motor, suitable for various places, especially for environments with explosion-proof requirements, a motor box 1 is provided on the top of the drill bit 5, the driving motor 10 is fixed on the inner wall of the motor box 1, and the front and rear sides of the motor box 1 are inlaid with heat dissipation nets;

[0039] Support components 3 are provided on both sides of the motor box 1, and the two support components 3 are symmetrically arranged on the left and right. The support components 3 include a telescopic rod 301 hinged at the outer end of the motor box 1, and the length of the telescopic rod 301 can be adjusted automatically. A supporting handle 302 is fixedly provided at one end of the telescopic rod 301 away from the motor box 1. By adjusting the length of the telescopic rod 301, the distance between the supporting handle 302 and the motor box 1 can be adjusted.

[0040] During the drilling process, the drill bit 5 is driven by the driving motor 10 to rotate, and the drill bit 5 contacts the ground. During the high-speed rotation, a hole is drilled in the ground to collect soil samples and then explore the mineral resources. The driving motor 10 is fixed inside the motor box 1. Therefore, the motor box 1 needs to be fixed during the drilling process to keep it still. Therefore, support components 3 are set on both sides of the motor box 1. The operator holds the supporting handle 302 and then fixes the motor box 1 through the telescopic rod 301 to prevent it from rotating. The telescopic rod 301 can be extended and retracted to adjust the distance between the supporting handle 302 and the motor box 1. The farther the distance, the greater the torque, and the more effort is saved when resisting the resistance of drilling. The torque during the supporting process is increased to reduce the force required during the supporting process, thereby achieving the purpose of saving effort.

[0041] In this embodiment: the supporting assembly 3 further includes a hinged piece 303 fixedly arranged at the outer end of the motor box 1, and a clamping plate 304 is fixedly arranged at one end of the telescopic rod 301 facing the motor box 1, and the hinged piece 303 is located inside the clamping plate 304 and is rotatably connected to the inner wall of the clamping plate 304, so that it can be freely unfolded or folded;

[0042] The hinge plate 303 is provided with an inner pin hole 306 which passes through the hinge plate 303, and the splint 304 is provided with an outer pin hole 305 which passes through the splint 304. The splint 304 can be inserted with a positioning pin after overlapping with the outer pin hole 305. When the two overlap, the telescopic rod 301 is perpendicular to the motor box 1, and the positioning pin can limit the rotation of the splint 304. The positioning pin needs to be pulled out before folding the telescopic rod 301.

[0043] Since the telescopic rod 301 is hinged to the outer end of the motor box 1 through the hinge piece 303 and the clamp plate 304, when in use, the telescopic rod 301 needs to be rotated to be perpendicular to the motor box 1. At this time, the outer pin hole 305 and the inner pin hole 306 coincide with each other, and the positioning pin can be inserted to fix the telescopic rod 301. After use, the positioning pin can be pulled out and the telescopic rod 301 can be rotated downward to be close to the motor box 1, so that the supporting component 3 can be folded up without taking up too much space and is easy to transport.

[0044] In this embodiment: a cover plate 11 is provided on the top of the motor box 1 by bolts, the output shaft of the driving motor 10 extends to the bottom of the motor box 1 and is fixedly provided with a connecting shaft 13, a protective cover 12 is provided at the bottom end of the motor box 1, and a plurality of blades 14 are fixedly provided at the outer end of the connecting shaft 13, and the blades 14 are located inside the protective cover 12, and the protective cover 12 can prevent personal injury caused by the rotating blades 14.

[0045] The connecting shaft 13 is driven to rotate at high speed by the driving motor 10, and the blades 14 are driven to rotate. After the blades 14 rotate, they drive the air flow to generate wind force, and the wind blows vertically downward toward the ground. During the drilling process, the generated debris reaches the ground and accumulates on the ground. The wind force can blow away the accumulated debris to prevent the debris from clogging the hole entrance and making it difficult to discharge the subsequent debris.

[0046] In this embodiment: the bottom end of the connecting shaft 13 extends to the bottom of the protective cover 12, the bottom end of the connecting shaft 13 is provided with a sleeve 9 through a sealed bearing sleeve, the bottom end of the sleeve 9 is rotatably connected with a sampling pipe 4 through a sealed bearing, the top of the sampling pipe 4 is communicated with the inside of the sleeve 9, a plurality of connecting arms 15 are provided between the sampling pipe 4 and the connecting shaft 13, the connecting arms 15 connect the connecting shaft 13 and the sampling pipe 4 so that the two can rotate synchronously, a negative pressure hose with a valve is fixedly provided on the rear side of the sleeve 9, one end of the negative pressure hose is connected to a sample container, and the inside of the sample container maintains a negative pressure state under the action of a negative pressure pump state, the model of the negative pressure pump is PCF5015N, the flow rate of the negative pressure pump is 15 / Min, the maximum output pressure is 100Kpa, the vacuum degree is 50Kpa, the working voltage is 24V, the load current is less than 0.5A, and it can work in an environment of 0-100℃. The PCF5015N negative pressure pump has the characteristics of high flow, high pressure, and high temperature resistance. It does not pollute the working medium, is maintenance-free, can operate continuously for 24 hours, allows the medium to be rich in water vapor, and can be installed in any direction. It is suitable for a variety of industrial and scientific research fields. The sample container uses a sealed cylinder with an inner diameter of 60-100mm and a height of 1.5-2m.

[0047] The soil sample during the drilling process is sucked into the sampling pipe 4, and under the action of negative pressure, it moves upward along the sampling pipe 4 into the sleeve 9, and is finally sucked into the sample container along the negative pressure hose, completing the collection of the soil sample. The connecting shaft 13 and the sampling pipe 4 are connected to each other through the connecting arm 15, so the connecting shaft 13 drives the sampling pipe 4 to rotate without affecting the collection and transportation of the soil sample.

[0048] In this embodiment: the bottom end of the sampling pipe 4 is fixedly connected to the top end of the drill bit 5, and a spiral blade 16 is fixedly provided at the outer end of the sampling pipe 4. The spiral blade 16 has a conveying function after rotation, and can convey the debris generated during the drilling process to the ground. Two sampling holes 17 are opened at the outer end of the sampling pipe 4. The diameter of the sampling pipe 4 is smaller than the diameter of the drill bit 5. The hole drilled on the ground by the exploration device forms a conveying channel. The high-speed rotating spiral blade 16 transports the debris generated during the drilling process upward along the hole to the ground. At the same time, under the action of negative pressure, a part of the debris is sucked into the sampling pipe 4 through the sampling holes 17, so as to collect soil samples.

[0049] In this embodiment: a fulcrum assembly 6 is provided on the rear side of the motor box 1, and the fulcrum assembly 6 includes a pedal 601 placed on the ground, and a plurality of anti-slip protrusions are fixedly provided on the pedal 601. A hydraulic cylinder 602 is fixedly provided on the top of the pedal 601. The model of the hydraulic cylinder 602 is 8040300-8MPa. The hydraulic cylinder has an inner diameter of 80mm, a piston rod diameter of 40mm, a piston stroke of 300mm, and a working pressure of 8MPa. The pressure is transmitted by hydraulic oil to drive the piston to move, thereby realizing various mechanical actions. A sliding hinge assembly 2 is provided on the top of the hydraulic cylinder 602 and the top of the cover plate 11.

[0050] The surveying device can use the lever structure to provide downward pressure for the drill bit 5 to drill a hole, and the fulcrum assembly 6 is supported at the fulcrum of the lever structure. The pedal 601 is located on the ground. A heavy object can be pressed on the top of the pedal 601, or a person can step on the pedal 601 to fix it to the ground. The hydraulic cylinder 602 can be extended and retracted to adjust the height of the fulcrum of the lever structure to adapt to the height of different operators.

[0051] In this embodiment: the sliding hinge assembly 2 includes a bracket 201, the bracket 201 is fixed to the top of the hydraulic cylinder 602 or the top of the cover plate 11, a connecting roller 202 is rotatably connected to the inner wall of the bracket 201, and a slot 203 penetrating the connecting roller 202 is opened on the connecting roller 202;

[0052] A fastening bolt is threadedly provided at the top of the connecting roller 202 of the sliding hinge assembly 2 at the hydraulic cylinder 602, and a plurality of balls 204 are fixedly provided on the inner wall of the slot 203 of the sliding hinge assembly 2 at the cover plate 11. The sliding hinge assembly 2 at the fulcrum assembly 6 can slide at the outer end of the lever structure to adjust the position of the fulcrum and thereby adjust the length of the lever arm.

[0053] In this embodiment: a pressure rod 7 is provided on the top of the cover plate 11, and the front end of the pressure rod 7 passes through the slot 203 of the sliding hinge assembly 2 at the cover plate 11, and the ball 204 on the inner wall of the slot 203 contacts the pressure rod 7, so the pressure rod 7 can slide relative to the sliding hinge assembly 2 while pressing down, and the sliding hinge assembly 2 at the fulcrum assembly 6 can be fixed to the outer end of the pressure rod 7 under the action of the fastening bolts, thereby fixing the position of the fulcrum, and the rear end of the pressure rod 7 extends backward and passes through the slot 203 of the sliding hinge assembly 2 at the hydraulic cylinder 602, and a U-shaped handle 8 is fixed to the rear end of the pressure rod 7, the U-shaped handle 8 can be held with both hands, and can also be carried on the shoulder, and the front-to-back spacing between the fulcrum assembly 6 and the motor box 1 is much smaller than the front-to-back spacing between the fulcrum assembly 6 and the U-shaped handle 8.

[0054] During the drilling process, the fulcrum assembly 6 can be used as a fulcrum, and the fulcrum assembly 6, the sliding hinge assembly 2, the pressure rod 7 and other components are formed into a lever structure. The operator lifts up the U-shaped handle 8 at the rear end of the pressure rod 7, and the front end of the pressure rod 7 presses down the motor box 1 as a whole, thereby providing downward pressure during the drilling process of the drill bit 5. Since the distance between the U-shaped handle 8 and the fulcrum assembly 6 is much larger than the distance between the fulcrum assembly 6 and the motor box 1, according to the principle of lever, the operator will save more effort when providing downward pressure, and it is easier to exert force by pulling the U-shaped handle 8 upward than by using the upper limbs to press down the motor box 1. At the same time, the U-shaped handle 8 can be supported on the shoulder, and the leg strength can be used to exert force upward, which can provide greater downward pressure and higher drilling efficiency.

[0055] 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.
