Description
Technical Field
[0001] The invention belongs to the technical field of geological survey, and in particular relates to a geological survey sampling device. Background Art
[0002] Hydrogeology, as a vital branch of geology, is a scientific field that specifically explores groundwater. In the process of development, this discipline has gradually been refined into multiple sub-fields, such as regional hydrogeology, which focuses on the study of large-scale groundwater systems; groundwater dynamics, which explores the dynamic process of groundwater flow; hydrogeochemistry, which studies the formation and evolution of groundwater chemical composition; water supply hydrogeology, which is committed to ensuring a safe and reliable groundwater supply; ore deposit hydrogeology, which focuses on hydrogeological problems in mining; soil improvement hydrogeology, which explores ways to improve soil quality through groundwater management. In recent years, the research boundaries of hydrogeology have been further expanded. Its cross-integration with geothermal science, seismology, environmental geology and other fields has not only promoted the development and utilization of geothermal energy and the improvement of earthquake prediction and early warning technology, but also provided new perspectives and methods for solving environmental problems such as geological disasters and groundwater pollution, and opened up many cutting-edge research directions.
[0003] Soil is an indispensable part of nature, composed of layers of minerals of varying thickness and complex composition. Soil differs significantly from the parent material layer, not only in their external morphology, but also in all aspects of physical, chemical and mineralogical properties. With the continuous changes in the current environment, the quality and condition of soil are also receiving increasing attention. Environmental supervision agencies are responsible for sampling and testing soil to assess its health and potential risks. Unfortunately, the current soil sampling equipment is still inefficient, especially when sampling soil, it is often not convenient to further stratify the soil samples for separate analysis and preservation. This limitation not only affects the accuracy and comprehensiveness of soil testing, but also brings considerable challenges to subsequent soil research and governance work. Summary of the invention
[0004] In view of this, the present invention provides a geological exploration sampling device to solve the problem that the soil sampling equipment in the prior art is still insufficient in efficiency, especially when sampling soil, it is often inconvenient to further stratify the soil samples for separate analysis and preservation.
[0005] The technical solution adopted by the present invention is as follows:
[0006] A geological exploration sampling device comprises two columns arranged at intervals and a top plate slidably connected to the two columns, the columns are provided with a lifting device for driving the top plate to move up and down, the top plate is provided with a first motor, the output shaft of the first motor is connected to a sampling barrel through a first electromagnetic bearing, a transmission shaft is provided inside the sampling barrel, the top of the transmission shaft is connected to the output shaft through a second electromagnetic bearing, and the bottom of the transmission shaft passes through the sampling barrel and is connected to a drill bit; a plurality of feed ports connected to an inner cavity thereof are penetrated through the side wall of the sampling barrel, and the plurality of feed ports are equidistantly spaced along the axial direction of the sampling barrel, a supporting plate corresponding to the number of feed ports is further provided in the sampling barrel, each supporting plate is located below the corresponding feed port, the two columns are arranged on the supporting plate, the top of the supporting plate is penetrated with a sampling port, and a fixing device which can be inserted into the soil is provided on the supporting plate.
[0007] In this technical solution, it should be noted that, first of all, regarding the material selection, the columns and the top plate are made of high-strength, corrosion-resistant steel, ensuring the structural stability and service life of the entire device. The first motor uses the mature and reliable existing technology in the current industry. As an electromagnetic device based on the law of electromagnetic induction, the motor can not only realize the conversion or transmission of electric energy, but also efficiently convert one form of electric energy into another form of electric energy. In this solution, the output shaft of the first motor has a strong driving force, which can drive the sampling tube or the drill bit to rotate respectively. The electromagnetic bearing adopts the existing technology. When the electromagnetic bearing is started, the electromagnetic bearing can use the electric field force and the magnetic field force to separate one axis from another axis, so that one axis cannot drive the other axis to rotate. When the electromagnetic bearing is turned off, the electromagnetic bearing connects one axis with another axis, so that one axis can drive the other axis to rotate. Specifically, when the drill is drilling, the first electromagnetic bearing is in the starting state and the second electromagnetic bearing is in the closing state, that is, the main shaft of the first motor will not drive the sampling barrel to rotate, but will drive the transmission shaft to rotate. When the sampling barrel is needed for soil sampling, the first electromagnetic bearing is closed and the second electromagnetic bearing is started, that is, the motor will drive the sampling barrel to rotate, but will not drive the transmission shaft to rotate. When the present scheme is implemented, the first motor and the lifting device are first started, and the lifting device will stably drive the top plate and the sampling barrel and the drill bit thereon to descend until they are close to the target soil layer. Subsequently, the first motor starts to work, and its output shaft rotates clockwise, and the transmission shaft and the drill bit are driven to rotate through the second electromagnetic bearing (the second electromagnetic bearing is closed, and the first electromagnetic bearing is started), and the drill bit gradually penetrates into the soil while rotating. When the sampling barrel reaches the specified depth in the soil, the first motor is started again. At this time, due to the action of the second electromagnetic bearing, the transmission shaft remains stationary, and the sampling barrel rotates clockwise with the output shaft driven by the first electromagnetic bearing (the first electromagnetic bearing is closed, and the second electromagnetic bearing is started). This rotation mode enables the feed ports at different heights on the sampling tube to sequentially introduce soil at different depths into the corresponding support plate, thereby realizing accurate collection of soil samples. In summary, in the present invention, through the designed lifting device, sampling tube, drill bit, first motor, and multiple feed ports and support plates with clever layout, the device can efficiently and accurately perform sampling operations on soil at different depths. In particular, due to the setting of the first electromagnetic bearing and the second electromagnetic bearing, it is ensured that the drill bit can rotate freely to break the soil while the sampling tube remains stable and does not rotate during the process of the device going deep into the soil. Because in the process of going deep into the soil, the non-rotation of the sampling tube can effectively reduce the possibility of non-target layer soil being mistakenly introduced into the sampling tube due to accidental contact with the feed port, thereby greatly improving the accuracy and purity of the sampling. When the sampling tube accurately reaches the specified depth of the soil, the sampling tube starts to rotate through the drive of the first motor. At this time, the drill bit remains stationary and no longer participates in the rotation action.This ingenious combination of rotation and stillness enables the sampling tube to smoothly and accurately introduce the soil at the target depth into the support plate through the feed port, completing effective sampling of soil at different depths. The entire process ensures the accuracy of sampling.
[0008] Preferably, the support plate is rotatably connected to the transmission shaft and the sampling barrel respectively.
[0009] In this technical solution, it should be noted that since the support plate is rotatably connected to the drive shaft and the sampling tube respectively, the support plate will not rotate when the sampling tube rotates for sampling. Therefore, the soil will fall on the top of the support plate more evenly, and there will be no excessive accumulation of soil at a certain position of the support plate. Secondly, after the sampling is completed, the staff can also remove the soil from various positions on the support plate by rotating the support plate.
[0010] Preferably, a receiving groove is provided at the bottom of each of the feed ports, a baffle is provided at the feed port for closing the feed port, the bottom of the baffle is connected to the bottom of the receiving groove by a first spring, sliders are provided at both ends of the baffle, a slide groove cooperating with the slider is provided on the sampling tube, the slider is slidably embedded in the slide groove, a mounting groove is provided at one end of the slider facing the inner cavity of the sampling tube, an insert block is slidably embedded in the mounting groove, one end of the insert block is connected to the bottom of the mounting groove by a second spring, and the other end extends out of the mounting groove, and the part of the insert block extending out of the mounting groove is an arc-shaped surface; a socket for inserting the insert block is provided on the slide groove, and when the baffle closes the feed port, the arc-shaped surface of the insert block is inserted into the socket.
[0011] In this technical solution, it should be noted that when the sampling tube goes deep into the soil for sampling, its feed port is very susceptible to being squeezed and invaded by the surrounding soil, causing soil from non-target layers to mix into the sampling tube, affecting the accuracy and purity of the sampling. Therefore, this solution cleverly designs a baffle device to effectively close the feed port during the soil drilling process. The specific principle is: in the initial state, the feed port is open, the baffle is located in the receiving slot, and the insert block is also located in the installation slot due to the limit of the slide slot. After that, the staff pulls the baffle upward to move the slider upward in the slide slot. When the installation slot is relative to the position of the socket, the insert block is inserted into the socket through the elastic force of the second spring, thereby fixing the baffle and completing the closure of the feed port. After that, the staff can start the first motor to implement the drilling work of the drill bit.
[0012] Preferably, a push block is slidably embedded in the socket, one end of the push block contacts the plug block in the socket, and the other end extends out of the sampling tube. A transmission structure is provided on the transmission shaft, and when the sampling tube rotates, the push block is pushed into the socket through the transmission structure.
[0013] In this technical solution, it should be noted that, after the sampling tube reaches the specified depth position in the soil accurately, it needs to rely on its own rotation to cut and collect soil samples. In this process, the feed port that was previously tightly closed by the baffle must be opened in time to ensure that the soil can smoothly enter the sampling tube. To this end, this solution conceives a set of transmission structures to work in coordination with the rotation of the sampling tube. Specifically, when the sampling tube starts to rotate, this rotational force will be transmitted to the push block through the transmission structure, and the push block will be pushed into the socket. As the push block goes deeper, it contacts the part of the socket that originally stuck the plug block, and gradually squeezes the plug block out of the socket and pushes it back into the installation slot. After this action is completed, the limiting effect of the socket on the plug block is immediately released. At this time, the first spring, using its own accumulated tension, gently pulls the baffle back from the closed position until the baffle falls steadily into the limiting slot. With the movement of the baffle, the feed port is automatically and smoothly opened, preparing for the subsequent soil sampling work. During the entire process, all components work in coordination, smoothly and efficiently.
[0014] Preferably, a first guide surface is provided on one side of the push block, the first guide surface is inclined, a first right-angle surface is provided on the side of the push block away from the first guide surface, the first right-angle surface is perpendicular to the jack; one end of the transmission structure is connected to the transmission shaft, and the other end extends to one side of the first guide surface along the radial direction of the transmission shaft. The transmission structure includes a fixed rod, the fixed rod is a cavity structure, a telescopic block is provided inside the fixed rod, one end of the telescopic block is connected to the inside of the fixed rod through a third spring, and the other end extends outside the fixed rod, a second guide surface is provided on one side of the telescopic block, the second guide surface is inclined, and the second guide surface faces the first right-angle surface of the push block, and a second right-angle surface is provided on the side of the telescopic block away from the second guide surface, the second right-angle surface is perpendicular to the fixed rod.
[0015] In this technical solution, it should be noted that the portion of the push block extending out of the socket is in the shape of a right triangle, the inclined surface of the right triangle is the first guide surface, and one of the portions in contact with the first guide surface is the first right-angled surface, and the portion of the telescopic block extending out of the fixed rod is also in the shape of a right triangle, the inclined surface of the right triangle is the second guide surface, and one of the portions in contact with the second guide surface is the second right-angled surface; since the first guide surface is an inclined surface, when the first guide surface is subjected to opposite pressure, the pressure will be decomposed through the inclined surface in the direction toward the socket, thereby causing the push block to be pressed into the socket. Similarly, since the second guide surface is an inclined surface, when the second guide surface is subjected to opposite pressure, the pressure will be decomposed through the inclined surface in the direction toward the fixed rod, thereby causing the push block to be pressed into the fixed rod; secondly, in this solution, since the first right-angled surface and the second right-angled surface The angle surfaces are all vertical surfaces. Therefore, when the first right-angle surface is subjected to an opposite thrust, the push block will not move. Similarly, when the second right-angle surface is subjected to an opposite thrust, it will not move either. Based on the above principle, this scheme combines the first guide surface, the second guide surface, the first right-angle surface and the second right-angle surface together so that each surface can cooperate with each other. The specific principle is: in the initial state, the feed port is open, the baffle is located in the storage groove, and the insert block is also located in the installation groove due to the limit of the slide groove. Afterwards, the staff pulls the baffle upward to move the slider upward in the slide groove. When the installation groove is relative to the position of the socket, the insert block is inserted into the socket through the elastic force of the second spring, thereby fixing the baffle and completing the closure of the feed port. Afterwards, the staff starts the first motor and the lifting device, and the lifting device will stably drive the top plate and the sampling tube and drill bit thereon to descend until they approach the target soil layer. Subsequently, the first motor starts working, and its output shaft rotates clockwise. The first motor starts working, and its output shaft rotates clockwise, driving the transmission shaft and the drill bit to rotate through the second electromagnetic bearing (the second electromagnetic bearing is closed, and the first electromagnetic bearing is started). The drill bit gradually penetrates into the soil while rotating. When the transmission shaft rotates clockwise, the fixed rod on the transmission shaft will also rotate clockwise. At this time, the second guide surface of the telescopic block on the fixed rod will continuously touch the first right-angle surface of the push block. In this process, the first right-angle surface will press the telescopic block into the fixed rod, and the push block will not be pressed into the socket, so that the baffle always closes the feed port. When the sampling tube reaches the specified depth in the soil, the first motor is started again. At this time, due to the action of the second electromagnetic bearing, the transmission shaft remains stationary, and the sampling tube rotates clockwise with the output shaft driven by the first electromagnetic bearing (the first electromagnetic bearing is closed and the second electromagnetic bearing is started). When the sampling tube rotates clockwise, the first guide surface of the push block will first touch the second right-angle surface of the telescopic block, so that the push block is pushed into the socket. As the push block goes deeper, it contacts the part of the socket where the plug block was originally stuck, and gradually squeezes the plug block out of the socket and pushes it back into the installation groove.After this action is completed, the limiting effect of the socket on the plug block is immediately released. At this time, the first spring uses its own accumulated tension to gently pull the baffle back from the closed position until the baffle falls steadily into the limiting groove. Subsequently, when the sampling tube rotates, the surrounding soil can be introduced into the supporting plate inside the sampling tube.
[0016] Preferably, a scraper is further provided on the feed port, one end of the scraper is hinged to one side of the feed port, the scraper is connected to the sampling tube via a fourth spring, and the scraper is located on the inner side of the baffle.
[0017] In this technical solution, it should be noted that when the sampling tube rotates, after the baffle retracts into the receiving groove, the baffle releases the limit on the scraper, and the scraper expands outward through the action of the fourth spring, thereby being able to guide the soil around the sampling tube into the sampling tube.
[0018] Preferably, the fixing device comprises a hinged rod, one end of which is hinged to the support plate, the other end of which is provided with a screw, which is threadedly connected to the hinged rod, and a plug is provided at the bottom of the screw.
[0019] In this technical solution, it should be noted that wheels are provided at the bottom of the pallet, which facilitates the movement of the pallet. Secondly, in order to fix the pallet in this solution to ensure the stability of the sampling tube during sampling, the present application also provides a hinged rod, a screw rod and a plug. When the pallet reaches the specified position, the hinged rod is rotated to expand the hinged rod, thereby increasing the coverage area of the pallet, and then the screw rod is rotated so that the screw rod drives the plug to move downward, and the plug is gradually inserted into the soil to fix the pallet.
[0020] Preferably, the support plate is made of iron, and a magnet is provided at one end of the hinged rod facing the support plate.
[0021] In this technical solution, it should be noted that when the support plate does not need to be fixed, the hinge rod is fixed to the support plate by the magnetic force of the magnet.
[0022] Preferably, a hand ring is provided on the top of the screw.
[0023] In this technical solution, it should be noted that the setting of the wristband makes it convenient for workers to rotate the screw.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0025] 1. In the present invention, the device can efficiently and accurately sample soil at different depths through the designed lifting device, sampling barrel, drill bit, first motor and multiple feed ports and support plates with clever layout. In particular, due to the arrangement of the first electromagnetic bearing and the second electromagnetic bearing, it is ensured that the drill bit can rotate freely to break the soil while the sampling barrel remains stable and does not rotate during the process of the device penetrating into the soil. Because the sampling barrel does not rotate during the process of penetrating into the soil, it can effectively reduce the possibility that non-target layer soil is mistakenly introduced into the sampling barrel due to accidental contact with the feed port, thereby greatly improving the accuracy and purity of the sampling. When the sampling barrel accurately reaches the specified depth of the soil, the sampling barrel starts to rotate through the drive of the first motor. At this time, the drill bit remains stationary and no longer participates in the rotation. This clever combination of rotation and stillness enables the sampling barrel to smoothly and accurately introduce the soil at the target depth into the support plate through the feed port, completing the effective sampling of soil at different depths. The whole process ensures the accuracy of sampling.
[0026] 2. In the present invention, a baffle device is cleverly designed to effectively close the feed port during the soil drilling process. The specific principle is: in the initial state, the feed port is open, the baffle is located in the receiving slot, and the insert block is also located in the installation slot due to the limit of the slide slot. After that, the staff pulls the baffle upward to make the slider move upward in the slide slot. When the installation slot and the plug hole are in relative positions, the insert block is inserted into the plug hole through the elastic force of the second spring to fix the baffle, thereby completing the closure of the feed port. After that, the staff can start the first motor to implement the soil drilling work of the drill bit;
[0027] 3. In the present invention, a transmission structure is conceived, which is intended to work in coordination with the rotation of the sampling barrel. Specifically, when the sampling barrel begins to rotate, this rotational force will be transmitted to the push block through the transmission structure, and the push block will be pushed into the socket. As the push block goes deeper, it contacts the part of the socket that originally stuck the plug block, and gradually squeezes the plug block out of the socket and pushes it back into the installation slot. After this action is completed, the limiting effect of the socket on the plug block is immediately released. At this time, the first spring, using its own accumulated pulling force, gently pulls the baffle back from the closed position until the baffle falls steadily into the limiting slot. With the movement of the baffle, the feed port is automatically and smoothly opened, preparing for the subsequent soil sampling work. During the whole process, the various components work together smoothly and efficiently;
[0028] 4. In the present invention, the first guide surface, the second guide surface, the first right-angle surface and the second right-angle surface are combined together so that the surfaces can cooperate with each other, so that when the sampling tube is working, the baffle can automatically return to the storage groove;
[0029] 5. In the present invention, when the baffle is retracted into the receiving groove, the baffle releases the limit on the scraper, and the scraper is expanded outward by the action of the fourth spring, thereby being able to guide the soil around the sampling tube into the sampling tube;
[0030] 6. In the present invention, since the support plate is rotatably connected to the transmission shaft and the sampling tube respectively, the support plate will not rotate when the sampling tube rotates to take samples, so the soil will fall on the top of the support plate more evenly, and there will be no excessive accumulation of soil at a certain position of the support plate. Secondly, after the sampling is completed, the staff can also take out the soil at various positions on the support plate by rotating the support plate;
[0031] 7. In the present invention, a hinged rod, a screw rod and a plug are provided. When the support plate reaches the specified position, the hinged rod is rotated to expand the hinged rod, thereby increasing the coverage area of the support plate. Then, the screw rod is rotated to drive the plug to move downward, and the plug is gradually inserted into the soil to fix the support plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Example 1
[0052] like Figure 1-Figure 11As shown, an embodiment of the present invention discloses a geological exploration sampling device, comprising two columns 1 arranged at intervals and a top plate 5 slidably connected to the two columns 1, the columns 1 are provided with a lifting device for driving the top plate 5 to move up and down, the top plate 5 is provided with a first motor 6, the output shaft 9 of the first motor 6 is connected to a sampling barrel 7 through a first electromagnetic bearing 11, the sampling barrel 7 is provided with a transmission shaft 12 inside, the top of the transmission shaft 12 is connected to the output shaft 9 through a second electromagnetic bearing 13, the transmission shaft 1 2 is connected to a drill bit 8 through a sampling tube 7; the side wall of the sampling tube 7 is provided with a plurality of feed ports 15 connected to its inner cavity, and the plurality of feed ports 15 are arranged equidistantly along the axial direction of the sampling tube 7. The sampling tube 7 is also provided with a supporting plate 14 corresponding to the number of feed ports 15, and each supporting plate 14 is located below the corresponding feed port 15. The two uprights 1 are arranged on a supporting plate 34, and a sampling port 35 is arranged on the top of the supporting plate 34. A fixing device that can be inserted into the soil is provided on the supporting plate 34. It should be noted that, first of all, regarding the material selection, the uprights 1 and the top plate 5 are made of high-strength, corrosion-resistant steel to ensure the structural stability and service life of the entire device. The first motor 6 uses the mature and reliable existing technology in the current industry. As an electromagnetic device based on the law of electromagnetic induction, the motor can not only realize the conversion or transmission of electric energy, but also efficiently convert one form of electric energy into another form of electric energy. In this solution, the output shaft 9 of the first motor 6 has a strong driving force, which can drive the sampling barrel 7 or the drill bit 8 to rotate. The electromagnetic bearing adopts the existing technology. When the electromagnetic bearing is started, the electromagnetic bearing can use the electric field force and the magnetic field force to separate one axis from another axis, so that one axis cannot drive the other axis to rotate. When the electromagnetic bearing is turned off, the electromagnetic bearing connects one axis with another axis, so that one axis can drive the other axis to rotate. Specifically, when the drill bit 8 is drilling soil, the first electromagnetic bearing 11 is in the starting state, and the second electromagnetic bearing 13 is in the closing state, that is, the main shaft of the first motor 6 will not drive the sampling barrel 7 to rotate, but will drive the transmission shaft 12 to rotate. When the sampling barrel 7 is needed for soil sampling, the first electromagnetic bearing 11 is closed and the second electromagnetic bearing 13 is started, that is, the motor will drive the sampling barrel 7 to rotate, and will not drive the transmission shaft 12 to rotate. When the present solution is implemented, the first motor 6 and the lifting device are first started, and the lifting device will stably drive the top plate 5 and the sampling barrel 7 and the drill bit 8 thereon to descend until they are close to the target soil layer. Subsequently, the first motor 6 starts to work, and its output shaft 9 rotates clockwise, driving the transmission shaft 12 and the drill bit 8 to rotate through the second electromagnetic bearing 13 (the second electromagnetic bearing 13 is closed and the first electromagnetic bearing 11 is started), and the drill bit 8 gradually penetrates into the soil while rotating.When the sampling barrel 7 reaches the specified depth in the soil, the first motor 6 is started again. At this time, due to the action of the second electromagnetic bearing 13, the transmission shaft 12 remains stationary, and the sampling barrel 7 rotates clockwise with the output shaft 9 under the drive of the first electromagnetic bearing 11 (the first electromagnetic bearing 11 is closed and the second electromagnetic bearing 13 is started). This rotation method enables the feed ports 15 at different heights on the sampling barrel 7 to sequentially introduce soil at different depths into the corresponding support plate 14, thereby achieving accurate collection of soil samples. In summary, in the present invention, through the designed lifting device, sampling barrel 7, drill bit 8, first motor 6, and the cleverly arranged multiple feed ports 15 and support plates 14, the device can efficiently and accurately perform sampling operations on soil at different depths. In particular, due to the arrangement of the first electromagnetic bearing 11 and the second electromagnetic bearing 13, it is ensured that when the device penetrates into the soil, the drill bit 8 can rotate freely to break the soil, while the sampling barrel 7 remains stable and does not rotate. Because the sampling barrel 7 does not rotate during the process of penetrating the soil, the possibility of non-target layer soil being mistakenly introduced into the sampling barrel 7 due to accidental contact with the feed port 15 can be effectively reduced, thereby greatly improving the accuracy and purity of sampling. When the sampling barrel 7 accurately reaches the specified depth of the soil, the sampling barrel 7 starts to rotate through the drive of the first motor 6. At this time, the drill bit 8 remains stationary and no longer participates in the rotation action. This ingenious combination of rotation and stillness enables the sampling barrel 7 to smoothly and accurately introduce the soil at the target depth into the support plate 14 through the feed port 15, completing the effective sampling of soil at different depths. The entire process ensures the accuracy of sampling.
[0053] In this embodiment, the support plate 14 is rotatably connected to the transmission shaft 12 and the sampling tube 7. It should be noted that since the support plate 14 is rotatably connected to the transmission shaft 12 and the sampling tube 7, the support plate 14 will not rotate when the sampling tube 7 rotates to take samples, so the soil will fall on the top of the support plate 14 more evenly, and there will not be too much soil accumulation at a certain position of the support plate 14. Secondly, after the sampling is completed, the staff can also take out the soil at various positions on the support plate 14 by rotating the support plate 14.
[0054] Example 2
[0055] like Figure 7-Figure 11As shown, this embodiment is substantially the same as the above embodiment, except that a receiving groove 16 is provided at the bottom of each feed port 15, a baffle 10 for closing the feed port 15 is provided at the feed port 15, the bottom of the baffle 10 is connected to the bottom of the receiving groove 16 through a first spring 17, sliders 23 are provided at both ends of the baffle 10, a slide groove 24 cooperating with the slide groove 23 is provided on the sampling tube 7, the slide groove 23 is slidably embedded in the slide groove 24, and the slide 23, a mounting groove 25 is provided at one end facing the inner cavity of the sampling tube 7, and a plug block 27 is slidably embedded in the mounting groove 25. One end of the plug block 27 is connected to the bottom of the mounting groove 25 through a second spring 26, and the other end extends outside the mounting groove 25, and the portion of the plug block 27 extending outside the mounting groove 25 is an arc-shaped surface; the slide groove 24 is provided with a plug hole 28 for the plug block 27 to be inserted, and when the baffle 10 closes the feed port 15, the arc-shaped surface of the plug block 27 is inserted into the plug hole 28. It should be noted that when the sampling tube 7 penetrates deep into the soil for sampling, its feed port 15 is very susceptible to being squeezed and invaded by the surrounding soil, resulting in the mixing of soil from non-target layers into the sampling tube 7, affecting the accuracy and purity of the sampling. Therefore, this solution cleverly designs a baffle 10 device to effectively close the feed port 15 during the drilling process. The specific principle is: in the initial state, the feed port 15 is open, the baffle 10 is located in the receiving groove 16, and the insert block 27 is also located in the installation groove 25 due to the limit of the slide groove 24. After that, the staff pulls the baffle 10 upward to make the slider 23 move upward in the slide groove 24. When the installation groove 25 is relative to the position of the socket 28, the insert block 27 is inserted into the socket 28 through the elastic force of the second spring 26, so as to fix the baffle 10 and complete the closure of the feed port 15. After that, the staff can start the first motor 6 to implement the drilling work of the drill bit 8.
[0056] like Fig.11As shown, in this embodiment, a push block 22 is slidably embedded in the socket 28, one end of the push block 22 contacts the plug block 27 in the socket 28, and the other end extends outside the sampling tube 7. A transmission structure is provided on the transmission shaft 12, and when the sampling tube 7 rotates, the push block 22 is pushed into the socket 28 through the transmission structure. It should be noted that after the sampling tube 7 accurately reaches the specified depth position in the soil, it needs to rely on its own rotation to cut and collect soil samples. In this process, the feed port 15 that was previously tightly closed by the baffle 10 must be opened in time to ensure that the soil can smoothly enter the sampling tube 7. To this end, this solution conceives a set of transmission structures, which are intended to work in conjunction with the rotation of the sampling tube 7. Specifically, when the sampling tube 7 starts to rotate, the rotational force is transmitted to the push block 22 through the transmission structure, and the push block 22 is pushed into the socket 28. As the push block 22 goes deeper, it contacts the part of the socket 28 that originally stuck the plug block 27, and gradually squeezes the plug block 27 out of the socket 28 and pushes it back into the installation slot 25. After this action is completed, the limiting effect of the socket 28 on the plug block 27 is immediately released. At this time, the first spring 17, using its own accumulated tension, gently pulls the baffle 10 back from the closed position until the baffle 10 falls steadily into the limiting slot. With the movement of the baffle 10, the feed port 15 is automatically and smoothly opened, preparing for the subsequent soil sampling work. During the whole process, all components work together smoothly and efficiently.
[0057] like Fig.11As shown, in this embodiment, a first guide surface 29 is provided on one side of the push block 22, and the first guide surface 29 is inclined. A first right-angle surface 30 is provided on a side of the push block 22 away from the first guide surface 29, and the first right-angle surface 30 is perpendicular to the insertion hole 28; one end of the transmission structure is connected to the transmission shaft 12, and the other end extends to one side of the first guide surface 29 along the radial direction of the transmission shaft 12. The transmission structure includes a fixed rod 20, and the fixed rod 20 is a cavity structure. A telescopic block 21 is provided in the fixed rod 20, one end of the telescopic block 21 is connected to the inside of the fixed rod 20 through a third spring 33, and the other end extends outside the fixed rod 20, a second guide surface 31 is provided on one side of the telescopic block 21, and the second guide surface 31 is inclined, and the second guide surface 31 faces the first right-angle surface 30 of the push block 22, and a second right-angle surface 32 is provided on a side of the telescopic block 21 away from the second guide surface 31, and the second right-angle surface 32 is perpendicular to the fixed rod 20. It should be noted that the portion of the push block 22 extending out of the insertion hole 28 is in the shape of a right triangle, the inclined surface of the right triangle is the first guide surface 29, and one of the first guide surfaces 29 is in contact with the first right-angled surface 30, and the portion of the telescopic block 21 extending out of the fixed rod 20 is also in the shape of a right triangle, the inclined surface of the right triangle is the second guide surface 31, and one of the second guide surfaces 31 is in contact with the second right-angled surface 32; since the first guide surface 29 is an inclined surface, when the first guide surface 29 is subjected to pressure from the opposite direction, the pressure will be decomposed through the inclined surface to the direction toward the insertion hole 28, thereby causing the push block 22 to be pressed into the insertion hole 28, and similarly, since the second guide surface 31 is an inclined surface, when the second guide surface 31 is subjected to pressure from the opposite direction, the pressure will be decomposed through the inclined surface to the direction toward the fixed rod 20, thereby causing the push block 22 to be pressed into the fixed rod 20; secondly, in this solution, since the first right-angled surface 30 and the second right-angled surface 32 are both vertical Therefore, when the first right-angled surface 30 is subjected to the opposite thrust, the push block 22 will not move. Similarly, when the second right-angled surface 32 is subjected to the opposite thrust, it will not move either. Based on the above principle, the present invention combines the first guide surface 29, the second guide surface 31, the first right-angled surface 30 and the second right-angled surface 32 together so that the various surfaces can cooperate with each other. The specific principle is: in the initial state, the feed port 15 is open, the baffle 10 is located in the receiving groove 16, and the insert block 27 is also in position due to the limit of the slide groove 24. In the installation groove 25, the staff then pulls the baffle 10 upwards, so that the slider 23 moves upwards in the slide groove 24. When the installation groove 25 is relative to the position of the socket 28, the plug block 27 is inserted into the socket 28 by the elastic force of the second spring 26, so as to fix the baffle 10 and complete the closure of the feed port 15. After that, the staff starts the first motor 6 and the lifting device, which will stably drive the top plate 5 and the sampling tube 7 and the drill bit 8 thereon to descend until they are close to the target soil layer.Subsequently, the first motor 6 starts working, and its output shaft 9 rotates clockwise. The first motor 6 starts working, and its output shaft 9 rotates clockwise, driving the transmission shaft 12 and the drill bit 8 to rotate through the second electromagnetic bearing 13 (the second electromagnetic bearing 13 is closed, and the first electromagnetic bearing 11 is started). The drill bit 8 gradually penetrates into the soil while rotating. When the transmission shaft 12 rotates clockwise, the fixed rod 20 on the transmission shaft 12 will also rotate clockwise. At this time, the second guide surface 31 of the telescopic block 21 on the fixed rod 20 will continuously touch the first right-angle surface 30 of the push block 22. In this process, the first right-angle surface 30 will press the telescopic block 21 into the fixed rod 20, and the push block 22 will not be pressed into the socket 28, so that the baffle 10 always closes the feed port 15. When the sampling tube 7 reaches the specified depth in the soil, the first motor 6 is started again. At this time, due to the action of the second electromagnetic bearing 13, the transmission shaft 12 remains stationary, and the sampling tube 7 rotates clockwise with the output shaft 9 driven by the first electromagnetic bearing 11 (the first electromagnetic bearing 11 is closed and the second electromagnetic bearing 13 is started). When the sampling tube 7 rotates clockwise, the first guide surface 29 of the push block 22 will first touch the second right-angle surface 32 of the telescopic block 21, so that the push block 22 is pushed into the socket 28. As the push block 22 goes deeper, it contacts the part of the socket 28 where the plug block 27 was originally stuck, and gradually squeezes the plug block 27 out of the socket 28 and pushes it back into the mounting groove 25. After this action is completed, the limiting effect of the socket 28 on the plug block 27 is immediately released. At this time, the first spring 17 uses its own accumulated tension to gently pull the baffle 10 back from the closed position until the baffle 10 falls steadily into the limiting groove. Subsequently, when the sampling tube 7 rotates, the surrounding soil can be introduced into the supporting plate 14 in the sampling tube 7.
[0058] Example 3
[0059] like Fig. 9 and Fig.10 As shown, this embodiment is substantially the same as the above embodiment, except that a scraper 18 is further provided on the feed port 15, one end of the scraper 18 is hinged to one side of the feed port 15, the scraper 18 is connected to the sampling barrel 7 through a fourth spring 19, and the scraper 18 is located on the inner side of the baffle 10. It should be noted that when the sampling barrel 7 rotates, after the baffle 10 retracts into the receiving groove 16, the baffle 10 releases the limit on the scraper 18, and the scraper 18 is expanded outward by the action of the fourth spring 19, thereby being able to introduce the soil around the sampling barrel 7 into the sampling barrel 7.
[0060] like Fig.10 As shown, in this embodiment, the top of the baffle 10 is provided with an inclined surface inclined toward the inside of the sampling tube 7. It should be noted that the inclined surface has a guiding effect, and the soil on the top of the baffle 10 can be guided to the inside of the sampling tube 7.
[0061] Example 4
[0062] like Figure 1 As shown, this embodiment is substantially the same as the above embodiment, except that the fixing device comprises an articulated rod 36, one end of which is articulated with the support plate 34, and the other end of which is provided with a screw 37, which is threadedly connected with the articulated rod 36, and a plug 39 is provided at the bottom of the screw 37. It should be noted that wheels are provided at the bottom of the support plate 34, and the wheels facilitate the movement of the support plate 34. Secondly, in order to fix the support plate 34 in this solution to ensure the stability of the sampling tube 7 during sampling, the present application is also provided with an articulated rod 36, a screw 37 and a plug 39. When the support plate 34 reaches the specified position, the articulated rod 36 is rotated to expand the articulated rod 36, thereby increasing the coverage area of the support plate 34, and then the screw 37 is rotated to drive the plug 39 to move downward, and the plug 39 is gradually inserted into the soil to fix the support plate 34.
[0063] like Figure 1 As shown, in this embodiment, the support plate 34 is made of iron material, and a magnet is provided at one end of the hinge rod 36 facing the support plate 34 .
[0064] It should be noted that when the support plate 34 does not need to be fixed, the hinge rod 36 is fixed to the support plate 34 by the magnetic force of the magnet.
[0065] like Figure 1 As shown, in this embodiment, a hand ring 38 is provided on the top of the screw rod 37. It should be noted that the provision of the hand ring 38 facilitates the worker to rotate the screw rod 37.
[0066] The working principle of the present invention is:
[0067] When the support plate 34 reaches the specified position, the hinge rod 36 is rotated to expand the hinge rod 36, thereby increasing the coverage area of the support plate 34, and then the screw 37 is rotated so that the screw 37 drives the plug 39 to move downward, and the plug 39 is gradually inserted into the soil to fix the support plate 34. In the initial state, the feed port 15 is open, the baffle 10 is located in the storage groove 16, and the plug block 27 is also located in the mounting groove 25 due to the limit of the slide groove 24. After that, the staff pulls the baffle 10 upward to make the slider 23 move upward in the slide groove 24. When the position of the mounting groove 25 is relative to the position of the socket 28, the plug block 27 is inserted into the socket 28 by the elastic force of the second spring 26, so as to fix the baffle 10 and complete the closure of the feed port 15. After that, the staff starts the first motor 6 and the lifting device, and the lifting device will stably drive the top plate 5 and the sampling tube 7 and the drill bit 8 thereon to descend until they approach the target soil layer. Subsequently, the first motor 6 starts working, and its output shaft 9 rotates clockwise. The first motor 6 starts working, and its output shaft 9 rotates clockwise, driving the transmission shaft 12 and the drill bit 8 to rotate through the second electromagnetic bearing 13 (the second electromagnetic bearing 13 is closed, and the first electromagnetic bearing 11 is started). The drill bit 8 gradually penetrates into the soil while rotating. When the transmission shaft 12 rotates clockwise, the fixed rod 20 on the transmission shaft 12 will also rotate clockwise. At this time, the second guide surface 31 of the telescopic block 21 on the fixed rod 20 will continuously touch the first right-angle surface 30 of the push block 22. In this process, the first right-angle surface 30 will press the telescopic block 21 into the fixed rod 20, and the push block 22 will not be pressed into the socket 28, so that the baffle 10 always closes the feed port 15. When the sampling tube 7 reaches the specified depth in the soil, the first motor 6 is started again. At this time, due to the action of the second electromagnetic bearing 13, the transmission shaft 12 remains stationary, and the sampling tube 7 rotates clockwise with the output shaft 9 driven by the first electromagnetic bearing 11 (the first electromagnetic bearing 11 is closed and the second electromagnetic bearing 13 is started). When the sampling tube 7 rotates clockwise, the first guide surface 29 of the push block 22 will first touch the second right-angle surface 32 of the telescopic block 21, so that the push block 22 is pushed into the socket 28. As the push block 22 goes deeper, it contacts the part of the socket 28 where the plug block 27 was originally stuck, and gradually squeezes the plug block 27 out of the socket 28 and pushes it back into the mounting groove 25. After this action is completed, the limiting effect of the socket 28 on the plug block 27 is immediately released. At this time, the first spring 17 uses its own accumulated tension to gently pull the baffle 10 back from the closed position until the baffle 10 falls steadily into the limiting groove. When the baffle 10 retracts into the storage groove 16, the baffle 10 releases the limitation on the scraper 18, and the scraper 18 is expanded outward by the action of the fourth spring 19. Subsequently, when the sampling tube 7 rotates, the surrounding soil can be introduced into the supporting plate 14 in the sampling tube 7 through the scraper 18.
