Description

Technical Field

[0001] The present invention relates to the technical field of exploration and sampling, and more particularly to a geological and mineral exploration and sampling device. Background Art

[0002] Mineral exploration, also known as ore deposit exploration, is a geological process conducted within legally required areas, applying effective exploration techniques and methods to provide reliable ore reserves and necessary geological, technical, and economic data for mines. During mineral exploration, soil sampling is necessary.

[0003] A Chinese patent document (CN118150233B) discloses a soil testing device for geological survey engineering, which states in the specification that "it includes a drive box, a support part, the support part is used to support, fix and shock-absorb the entire running device, the support part includes armrests fixedly installed on both sides of the drive box for taking and placing the device, the lower side of the drive box is fixedly installed with a support box, and the four sides of the support box are fixedly installed with shock-absorbing components for supporting and shock-absorbing the entire device. The advantages are: the present invention can simultaneously take multiple samples of the soil around the sampling point without repeated sampling, thereby improving the detection efficiency of the device, and the device can separately detect the water content and sand content of multiple samples to avoid mutual interference between the two tests and affect the detection data. At the same time, the device takes out samples without manpower, effectively avoiding sample contamination caused by human factors, and improving the accuracy of the detection data." However, in actual use, there is still a problem that the equipment is easily damaged and damaged when taking soil samples, affecting the accuracy of the sample data and the service life of the equipment.

[0004] Most common soil sampling equipment currently available on the market uses a drilling operation principle, whereby a high-speed rotating drill bit is used to drill and sample the soil. However, in practical applications, this technical solution has two significant drawbacks: First, during the drilling operation, the intense friction between the drill bit and the soil layer instantly generates high temperatures, which damages the drill bit; second, during soil sample extraction, existing devices generally lack an effective stratification and isolation mechanism. Soil samples from different depths are easily cross-mixed during the ascent process, seriously affecting the precise determination of the vertical distribution characteristics of the soil profile in subsequent laboratory analysis. In view of this, we propose a geological and mineral exploration sampling device. Summary of the Invention

[0005] The purpose of the present invention is to provide a geological and mineral exploration sampling equipment to solve the technical problems that the existing soil sampling equipment generates heat due to friction with the ground during drilling, thereby affecting the quality of the soil sample and shortening the life of the drill bit, and soil at different depths is easily mixed when discharged, thereby reducing the accuracy of the detection data.

[0022] Compared with the prior art, the present invention has the following significant improvements:

[0023] 1. The present invention is designed with a punching assembly, a humidifying assembly, and an inner cylinder assembly. When sampling, the driver runs forward at a low speed. At this time, the first and second handles need to be grasped to maintain the stability of the device during sampling. At the same time, the water pump is started. When the driver runs, the inner cylinder assembly will rotate accordingly and synchronously drive the punching assembly to rotate. At this time, the device is squeezed downward, gradually extending into the ground. The inner cylinder assembly will collect soil samples. As the punching assembly and inner cylinder assembly move downward, the elastic assembly contacts the ground and continues to contract under pressure. At this time, the elastic assembly will open the humidifying assembly, causing the humidifying assembly to gradually discharge liquid as the punching assembly penetrates deeper. After the drilling is completed, the device needs to be taken out and the drive needs to be run in reverse at high speed. The drilling component is extended and locked, so that the inner cylinder component gradually extends and discharges the spiral blades and soil. The device will discharge liquid according to the depth of the drilling process. On the one hand, it can reduce the temperature of the drilling component and the inner cylinder component during operation, avoid damage due to overheating, and ensure the safety of the device. On the other hand, humidifying the soil can reduce the difficulty of sampling. After sampling, the sample can be discharged by simply running the drive in reverse, and the spiral blades can avoid cross-mixing of the samples, ensuring the accuracy of the device's detection and collection of soil sample data.

[0024] 2. The present invention also designs a humidifying component and an elastic component. When the driver runs forward at a low speed, the driving shaft below it will drive the screw to rotate. Since the screw is located in the nut, the screw will drive the limit block and the inner cylinder to rotate through the nut and the drill rod. Since the inner cylinder is connected to the punching cylinder, the punching cylinder will punch holes in the ground when the driver runs forward at a low speed. As the punching position goes deeper, the extrusion plate contacts the ground and continuously pushes the first elastic telescopic rod to contract. At this time, the mounting block will drive the positioning frame and the sealing rod to move upward through the sleeve and the slide cylinder, so that the liquid in the liquid outlet pipe enters the drain pipe and is quickly discharged along the exposed nozzle. As the drilling progresses, the liquid first The elastic telescopic rod remains in a contracted state due to the downward pressure applied, so that the liquid can be continuously discharged, ensuring that the liquid continues to moisten the soil during the drilling process to avoid loss of the drilling barrel and difficulty in drilling due to overheating, thereby protecting the drilling efficiency. Since drilling inevitably requires moistening the soil to reduce soil strength, it is necessary to ensure liquid discharge when using the device, and reduce soil hardness by humidifying the soil, thereby protecting the service life of the drilling barrel, drill rod and spiral blades. The cooperation between the sleeve and the slide can ensure that the drainage pipe and the liquid outlet pipe can rotate with the drilling barrel without affecting the height movement of the sealing rod, thereby ensuring the stability of the device during use.

[0025] 3. The present invention also designs the inner cylinder assembly, the punching assembly and the connecting assembly. When the driver runs in reverse at high speed, the counterweight block will be discharged under the action of centrifugal force and dock with the gap of the docking block. At this time, the punching cylinder is locked, and the inner cylinder, the limit block and the drill rod are difficult to rotate, while the screw rod will continue to rotate. The thread on the surface of the screw rod can quickly discharge the drill rod and the spiral blade out of the inner cylinder along the limit groove. At this time, the soil sample collected in the gap of the spiral blade will also be discharged together. In this way, the device can quickly discharge the collected soil sample, further reducing the difficulty of using the device. Moreover, with the design of the spiral blade, cross-mixing of the sample soil can also be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figures 1 to 8 As shown, the present invention relates to a geological mineral exploration sampling device, comprising a driver 11, a punching cylinder 251 and a spiral blade 267, and further comprising:

[0044] The driving mechanism 1 includes a driver 11, a first handle 12 connected to the driver 11, a second handle 13 and a water pump 14, wherein the water pump 14 is located below the driver 11 and the second handle 13 is arranged on one side of the driver 11; and the sampling mechanism 2 includes a water tank 21, a guide tube 22 arranged below the water tank 21, a connecting component 23 connected to the guide tube 22, an elastic component 24, a punching component 25, an inner cylinder component 26 arranged in the punching component 25, and a humidifier connected to the elastic component 24. Component 27, wherein the humidifying component 27 is connected to the water tank 21, the elastic component 24 is located outside the punching component 25, and the punching component 25 is located below the connecting component 23. By designing the punching component 25, the humidifying component 27 and the inner cylinder component 26, when sampling, the driver 11 runs forward at a low speed. At this time, the first handle 12 and the second handle 13 need to be grasped to maintain the stability of the device when sampling. At the same time, the water pump 14 is started. When the driver 11 is running, the inner cylinder component 26 will rotate accordingly and synchronously drive the punching component 2 5 rotates, squeezing the device downward so that it gradually extends into the ground. The inner cylinder assembly 26 collects soil samples. As the punching assembly 25 and the inner cylinder assembly 26 move downward, the elastic assembly 24 contacts the ground and continues to contract under pressure. At this time, the elastic assembly 24 activates the humidifying assembly 27, causing the humidifying assembly 27 to gradually discharge liquid as the punching assembly 25 penetrates deeper. After drilling is completed, the device needs to be removed and the driver 11 is reversed at high speed. The punching assembly 25 extends and locks, causing the inner cylinder assembly 26 to gradually extend and discharge the spiral blades 267 and soil. During the drilling process, the device discharges liquid according to the depth of the drilling. On the one hand, it can reduce the operating temperature of the punching assembly 25 and the inner cylinder assembly 26, prevent them from being damaged by overheating, and ensure the safety of the device. On the other hand, humidifying the soil can reduce the difficulty of sampling. After sampling is completed, the driver 11 only needs to be reversed to discharge the sample. The spiral blades 267 can prevent cross-mixing of the samples, thereby ensuring the accuracy of the soil sample data collected by the device.

[0045] The top of the driver 11 is fixedly connected to the first handle 12, and one side of the driver 11 is fixedly connected to the second handle 13. The water pump 14 is fixedly connected to the bottom of the driver 11. The water tank 21 is an annular cylinder. The bottom of the water tank 21 is connected to the top of several diversion tubes 22 through a valve. By providing a valve under the water tank 21, the device can stop the discharge of liquid when the soil hardness is low or after the soil is moistened, thereby improving the controllability of the device.

[0046] The water tank 21 is connected to the connecting assembly 23 through several guide tubes 22. The bottom of the water tank 21 is fixedly connected to the top of the elastic assembly 24, and the elastic assembly 24 is fixedly connected to the humidifying assembly 27. The top of the humidifying assembly 27 is connected to the bottom of the connecting assembly 23. The punching assembly 25 is located below the connecting assembly 23. The inner wall of the punching assembly 25 is fixedly connected to the inner cylinder assembly 26. The driving shaft below the driver 11 is fixedly connected to the inner cylinder assembly 26. The punching assembly 25 is sleeved on the outside of the driving shaft below the driver 11. The water tank 21 is fixedly connected to the outside of the water pump 14, and the water pump 14 is connected to the water tank 21. When the driver 11 runs in reverse at a low speed, the first handle 12 and the second handle 13 need to be pulled upward until the part of the device extended into the soil is taken out. Since the punching assembly 25 and the inner cylinder assembly 26 are in a rotating state, the difficulty of removing the device is reduced, and the discharge of liquid can play a humidifying and lubricating effect, further reducing the resistance when removing the device.

[0047] The connecting component 23 includes a sleeve 231, a plurality of liquid inlet holes 232 are provided on the top of the sleeve 231, a movable groove 233 is provided in the sleeve 231, and a limit plate 234 is slidably connected in the movable groove 233. The limit plate 234 is annular, and the cross section of the limit plate 234 is T-shaped. The shape of the limit plate 234 is adapted to the shape of the movable groove 233, and a plurality of liquid outlet holes 235 are provided below the limit plate 234. The inner wall of the sleeve 231 is fixedly connected to a plurality of docking blocks 236. The top of the sleeve 231 is connected to the bottom of the water tank 21 through a plurality of flow guide pipes 22, and the bottom of the limit plate 234 is connected to the humidifying component 27 through a plurality of liquid outlet holes 235. The elastic component 24 includes four first elastic telescopic rods 241, and the bottom ends of the four first elastic telescopic rods 241 are fixedly connected to the mounting block 242. The bottom end of the first elastic telescopic rod 241 is connected to the mounting block 242 through the mounting block 242. The connecting rod 243 is fixedly connected, and the bottom ends of the four connecting rods 243 are fixedly connected to the same extrusion plate 244. The extrusion plate 244 is annular and is located outside the punching assembly 25. The top end of the first elastic telescopic rod 241 is fixedly connected to the bottom of the water tank 21. The first elastic telescopic rod 241 is fixedly connected to the humidifying assembly 27 through the mounting block 242. Since the sliding sleeve 231 is fixed to the water tank 21 through the guide tube 22, and the limit plate 234 slides inside it, when the discharge pipe 275 rotates together with the punching cylinder 251, the limit plate 234 will rotate in the sliding sleeve 231, ensuring that the liquid outlet pipe 276 can be connected to the water tank 21 through the sliding sleeve 231, and the sliding sleeve 231 is in a fixed state, so that when the driver 11 runs at high speed, the docking block 236 will fix the punching cylinder 251, which is convenient for the discharge of the drill rod 265 and the spiral blade 267, thereby improving the automation of the device.

[0048] By providing a groove on the outside of the punching cylinder 251 and arranging the drainage pipe 275 and the liquid outlet pipe 276 inside the groove, it is possible to avoid excessive contact between the soil and the drainage pipe 275 and the liquid outlet pipe 276 during the punching process, thereby preventing excessive wear of the drainage pipe 275 and the liquid outlet pipe 276, thereby ensuring the service life of the device. At the same time, by extending the drainage pipe 275 deep into the ground, liquid can be discharged in real time, thereby humidifying the soil while sampling, reducing the difficulty of sampling and improving the efficiency of the device.

[0049] Since the equipment needs to be pressed down during the drilling process, the device is pushed to continue drilling into the soil to complete the sampling process. During the downward movement and drilling process, the mounting block will drive the positioning frame and the sealing rod to move upward through the sleeve and the slide, so that the liquid in the liquid outlet pipe enters the drain pipe and is quickly discharged along the exposed nozzle, thereby reducing the difficulty of using the device, ensuring that liquid is discharged during drilling, and moistening the surrounding soil, ensuring the efficiency of the drilling process and the service life of the equipment.

[0050] The punching assembly 25 includes a punching cylinder 251, and four grooves are provided on the outer side of the punching cylinder 251. The top of the punching cylinder 251 is fixedly connected to a mounting ring 252, and a bearing 253 is provided in the mounting ring 252. The bearing 253 is clamped on the top of the punching cylinder 251. A plurality of second elastic telescopic rods 254 are fixedly connected to the outside of the mounting ring 252. The second elastic telescopic rod 254 is composed of a spring and a telescopic rod. Since its own elastic design value is greater than the pulling force generated by the counterweight block 255 when the equipment is running at a low speed, under the low-speed running condition, the pulling force of the counterweight block 255 is not enough to cause the second elastic telescopic rod 254 to displace. When the equipment switches to the high-speed running mode and the driver 11 runs at a higher speed, the situation changes. As the speed increases, the counterweight block 255 The pulling force generated by inertia gradually increases. When the pulling force exceeds the elastic force threshold of the second elastic telescopic rod 254, the second elastic telescopic rod 254 begins to gradually stretch under the action of the pulling force. As the stretching process continues, the counterweight block 255 gradually moves into the gap space formed by the multiple docking blocks 236. Since the driver 11 continues to maintain a high-speed operation state, the counterweight block 255 collides violently with the docking block 236 under the action of inertia. At this time, the second elastic telescopic rod 254 is instantly blocked by the strong friction force generated between the counterweight block 255 and the docking block 236, thereby achieving mechanical docking with the docking block 236 and forming a rigid locking state. In this locked state, the continuous rotation of the screw rod 266 will directly drive the nut 264 to generate axial displacement;

[0051] The other ends of the several second elastic telescopic rods 254 are fixedly connected to counterweight blocks 255. The shape of the counterweight blocks 255 is adapted to the shape of the gap between the two adjacent docking blocks 236. The bearing 253 is sleeved on the outside of the drive shaft below the driver 11. The horizontal position of the counterweight blocks 255 is adapted to the horizontal position of the docking blocks 236. The inner wall of the punching cylinder 251 is fixedly connected to the inner cylinder assembly 26. The humidifying assembly 27 is located in the groove opened on the outside of the punching cylinder 251. The bottom end of the punching cylinder 251 is provided with an inclined groove. By designing the humidifying assembly 27 and the elastic assembly 24, when the driver 11 is running in the forward low speed direction, the driving shaft below it will drive the screw rod 266 to rotate. Since the screw rod 266 is located in the nut 264, the screw rod 266 will drive the limit block 263 and the inner cylinder 261 to rotate through the nut 264 and the drill rod 265. And because the inner cylinder 261 and the punching cylinder 251 is connected, so the punching cylinder 251 will punch holes in the ground when the driver 11 runs forward at low speed. As the punching position goes deeper, the extrusion plate 244 contacts the ground and continues to push the first elastic telescopic rod 241 to contract. At this time, the mounting block 242 will drive the positioning frame 273 and the sealing rod 274 to move upward through the sleeve 271 and the slide 272, so that the liquid in the liquid outlet pipe 276 enters the drainage pipe 275 and is quickly discharged along the exposed nozzle 277, thereby reducing the soil hardness by humidifying the soil, thereby ensuring the service life of the punching cylinder 251, the drill rod 265 and the spiral blade 267, and the cooperation of the sleeve 271 and the slide 272 can ensure that the drainage pipe 275 and the liquid outlet pipe 276 can rotate together with the punching cylinder 251 without affecting the height movement of the sealing rod 274, thereby ensuring the stability of the device when in use.

[0052] The inner cylinder assembly 26 includes an inner cylinder 261, the inner wall of the inner cylinder 261 is provided with a plurality of limiting grooves 262, and a limiting block 263 is slidably connected in the plurality of limiting grooves 262, a nut 264 is fixedly connected to the upper portion of the limiting block 263, a drill rod 265 is fixedly connected to the lower portion of the limiting block 263, a screw rod 266 is connected to the inner thread of the nut 264, the bottom end of the screw rod 266 passes through the limiting block 263 and is located in the drill rod 265, a spiral blade 267 is fixedly connected to the outside of the drill rod 265, and the inner cylinder 261 is provided with a plurality of limiting grooves 262. The top of the screw rod 266 is fixedly connected to the drive shaft below the driver 11, the inner cylinder 261 is fixedly connected to the punching cylinder 251, the humidifying assembly 27 includes a sleeve 271, a slide 272 is sleeved in the sleeve 271, four positioning frames 273 are fixedly connected in the slide 272, and the four positioning frames 273 are fixedly connected to the four sealing rods 274 respectively. The four sealing rods 274 are slidably connected in the four drainage pipes 275, the drainage pipe 275 is connected to the liquid outlet pipe 276, and the four drainage pipes 275 are fixed outside. It is connected to a plurality of nozzles 277, the top of the liquid outlet pipe 276 is connected to the water tank 21, the sleeve 271 is fixedly connected to the four mounting blocks 242, the four drainage pipes 275 and the four liquid outlet pipes 276 are respectively located in the four grooves opened outside the punching cylinder 251, and by designing the inner cylinder assembly 26, the punching assembly 25 and the connecting assembly 23, when the driver 11 runs in the reverse high-speed direction, the counterweight block 255 will be discharged under the action of centrifugal force and dock with the gap of the docking block 236. At this time, the punching cylinder 251 is locked and the inner cylinder 261 is closed. , the limit block 263 and the drill rod 265 are difficult to rotate, while the screw rod 266 will continue to rotate. The thread on the surface of the screw rod 266 can quickly discharge the drill rod 265 and the spiral blade 267 out of the inner cylinder 261 along the limit groove 262. At this time, the soil sample collected in the gap of the spiral blade 267 will also be discharged together. In this way, the device can quickly discharge the collected soil sample, further reducing the difficulty of using the device. Moreover, with the design of the spiral blade 267, cross-mixing of the sample soil can also be avoided.

[0053] Working principle: A geological and mineral exploration sampling device. When in use, when the driver 11 is running in the forward low speed, it is necessary to grasp the first handle 12 and the second handle 13 to maintain the stability of the device during sampling. At the same time, the water pump 14 is started. When the driver 11 is running, the inner cylinder assembly 26 rotates accordingly, and synchronously drives the punching assembly 25 to rotate. At this time, the device is squeezed downward so that it gradually extends into the ground. The inner cylinder assembly 26 will collect soil samples. As the punching assembly 25 and the inner cylinder assembly 26 move downward, the elastic assembly 24 contacts the ground and continues to shrink under pressure. At this time, the elastic assembly 24 will turn on the humidifying assembly 27, so that the humidifying assembly 27 gradually discharges liquid as the punching assembly 25 goes deeper. After the drilling is completed, the device needs to be taken out and the driver 11 is run in the reverse high speed. The punching assembly 25 extends and locks, and the inner cylinder assembly 26 gradually extends to discharge the spiral blade 267 and the soil.

[0054] When the driver 11 is running forward at a low speed, the driving shaft below it will drive the screw rod 266 to rotate. Since the screw rod 266 is located in the nut 264, the screw rod 266 will drive the limit block 263 and the inner cylinder 261 to rotate through the nut 264 and the drill rod 265. Since the inner cylinder 261 is connected to the punching cylinder 251, the punching cylinder 251 will punch holes in the ground when the driver 11 is running forward at a low speed. As the punching position deepens, the extrusion plate 244 contacts the ground and continuously pushes the first elastic telescopic rod 241 to contract. At this time, the mounting block 242 will drive the positioning frame 273 and the sealing rod 274 to move upward through the sleeve 271 and the slide cylinder 272, so that the liquid in the liquid outlet pipe 276 enters the drain pipe 275 and is quickly discharged along the exposed nozzle 277.

[0055] When the driver 11 is running in the reverse direction at a low speed, the first handle 12 and the second handle 13 need to be pulled upward until the portion of the device extending into the soil is removed;

[0056] When the balancing weight is running at high speed, the centrifugal force when the balancing weight rotates is greater than the elastic force of the second elastic telescopic rod, so the balancing weight will be released. When the balancing weight is running at low speed, the centrifugal force is insufficient and the balancing weight will not slide out.

[0057] When the driver 11 runs in the reverse direction at high speed, the counterweight block 255 will be discharged under the action of centrifugal force and dock with the gap of the docking block 236. At this time, the punching cylinder 251 is locked, the inner cylinder 261, the limit block 263 and the drill rod 265 are difficult to rotate, and the screw rod 266 will continue to rotate. The thread on the surface of the screw rod 266 can quickly discharge the drill rod 265 and the spiral blade 267 out of the inner cylinder 261 along the limit groove 262. At the same time, the soil sample collected in the gap of the spiral blade 267 will also be discharged together.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
