Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a soil sampling device for deep soil sampling. Background Art

[0002] At present, the collection and sampling of soil samples is the foundation of soil science research and geological exploration, and provides a material basis for the determination of the physical and chemical properties of soil samples. There are many methods for soil sampling. One method is to use a spiral drill rod to drill into the ground for sampling. In this way, the upper soil and the lower soil will be mixed together, especially for situations where deep sampling is required, and the soil sampling is inaccurate; there is also a method of impacting the sampling tube, inserting the sampling tube into the soil layer, and then bringing out the soil sample through the inside of the sampling tube. This method is not easy to insert into deeper soil layers, especially when the upper soil layer is affected by stones and other debris. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a soil sampling device for deep soil sampling. First, a hollow spiral drill rod is used to drill into the soil layer to avoid the influence of stones and other debris in the upper layer of the soil. Then, the undisturbed soil sampling tube is moved downward in the deep soil layer to allow the undisturbed soil sampling tube to obtain undisturbed soil samples in the deep soil layer to avoid the soil in the upper layer and the soil in the lower layer of the soil sample from mixing together. Then, the hollow spiral drill rod is moved up a distance to allow an arc groove to extend from the bottom of the hollow spiral drill rod. The shading soil sampling mechanism and the shading soil holding mechanism cooperate to complete the relatively closed collection and sampling of deep soil samples underground, thereby improving the accuracy of deep soil sample collection and avoiding excessive influence on the soil samples when the soil samples are held above the ground. The problems in the background technology can be effectively solved.

[0004] To achieve the above object, the present invention provides the following technical solution: a soil sampling device for deep soil sampling, comprising a soil deep drilling mechanism, the soil deep drilling mechanism comprising a drilling platform, the middle part of the drilling platform is rotatably connected to the top of a hollow spiral drill rod, and further comprising: The undisturbance soil sampling mechanism comprises a sampling hollow column, wherein the sampling hollow column is inserted in the hollow spiral drill rod, the bottom end of the sampling hollow column is connected to the top end of the undisturbance soil sampling cylinder, and a slide cylinder is vertically slidably installed in the undisturbance soil sampling cylinder; A light-shielding soil sampling mechanism is mounted on the slide cylinder and the sampling hollow column; The shading soil containing mechanism is installed in the slide cylinder.

[0005] Furthermore, the top of the sampling hollow column is connected to the hollow column lifting assembly, the bottom end of the undisturbed soil sampling cylinder is connected to the soil cutting and penetration assembly, the outer side of the undisturbed soil sampling cylinder is provided with a clamping hole, and the top of the slide is connected to the slide lifting assembly, the bottom end of the slide is connected to a cone, and the side of the slide is provided with a taking and placing groove.

[0006] The drill rod lifting assembly is installed on sampling vehicles such as engineering vehicles and pickup trucks. The drill rod lifting assembly is used to drive the hollow auger rod to move up and down through the drilling platform, and the power assembly is used to drive the hollow auger rod to rotate. The hollow auger rod descends during the rotation process to drill a hole on the ground and bring the soil below the ground to the ground. As the hollow auger rod drills into the soil layer, the bottom end of the sampling hollow column and the undisturbed soil sampling barrel in the undisturbed soil sampling mechanism also enter the soil layer. In this process, the bottom end of the sliding barrel closes the bottom end of the undisturbed soil sampling barrel, and the cone promotes the soil in the center of the bottom of the hollow auger rod to move around and finally is taken away upward by the thread of the hollow auger rod. After the hollow auger rod penetrates into the required depth, the drill rod lifting assembly and the power assembly stop working, and the sliding barrel lifting assembly drives the sliding barrel to move upward in the undisturbed soil sampling barrel until it stops when the bottom end of the sliding barrel corresponds to the top of the undisturbed soil sampling barrel, and then the hollow column lifting assembly drives the sampling hollow column relative to The hollow auger rod descends, and the sampling hollow column drives the undisturbed soil sampling tube to descend, and the deep undisturbed soil sample enters the undisturbed soil sampling tube. After the undisturbed soil sample fills the undisturbed soil sampling tube, the hollow column lifting assembly stops working, and the sampling work of the undisturbed soil sample is realized through the undisturbed soil sampling tube. The setting of the card hole one is convenient for installing the wrench tool and rotating the undisturbed soil sampling tube, so as to facilitate the disassembly and assembly of the undisturbed soil sampling tube at the bottom of the sampling hollow column. The setting of the soil cutting deep component is convenient for breaking the soil at the bottom of the undisturbed soil sampling tube, so that the undisturbed soil sampling tube is easier to descend in the deep soil and allow the deep soil to enter the undisturbed soil sampling tube. The light-shielding soil sampling mechanism can allow the deep soil sample to enter the light-shielding soil holding mechanism as the sampling hollow column rotates, and the soil sample is encapsulated in the deep soil position through the light-shielding soil holding mechanism, so as to avoid the soil sample being affected by the soil sample being placed above the ground, and reduce the influence of too much air or sunlight on the soil sample on the ground.

[0007] Furthermore, the hollow column lifting assembly includes a hydraulic cylinder, a connecting plate and a hollow column bearing. The top of the sampling hollow column is rotatably connected to one end of the connecting plate through the hollow column bearing, and the bottom of the other end of the connecting plate is fixedly connected to the top of the hydraulic cylinder, and the bottom of the hydraulic cylinder is fixedly connected to the top of the drilling platform. When the hydraulic cylinder is shortened, the sampling hollow column is driven to descend relative to the hollow spiral drill rod through the connecting plate, and when the hydraulic cylinder is extended, the sampling hollow column is driven to rise relative to the hollow spiral drill rod through the connecting plate. The setting of the hollow column bearing allows the sampling hollow column to rotate relative to the hollow spiral drill rod.

[0008] Furthermore, the slide tube lifting assembly includes an inner fixed frame, an electric lifting telescopic rod and an arch frame, the top of the slide tube is fixedly connected to the arch frame, the top of the arch frame is fixedly connected to the bottom end of the electric lifting telescopic rod, and the top end of the electric lifting telescopic rod is installed on the inner wall of the sampling hollow column through the inner fixed frame. The inner fixed frame is used to install the electric lifting telescopic rod, and when the electric lifting telescopic rod is extended or shortened, it can drive the slide tube to move up and down relative to the undisturbed soil sampling tube by driving the arch frame.

[0009] Furthermore, the soil cutting and penetration component includes a soil cutting ring, an internal threaded sleeve and a second clamping hole. The inner diameter of the soil cutting ring is the same as the inner diameter of the undisturbed soil sampling barrel, and the outer diameter of the bottom end of the soil cutting ring is smaller than the outer diameter of the top end. The top of the soil cutting ring is connected to the internal threaded sleeve, and the outer side of the internal threaded sleeve is provided with a second clamping hole. The internal threaded sleeve is threadedly connected to the bottom end of the undisturbed soil sampling barrel. The internal threaded sleeve makes it convenient for the soil cutting ring to be installed at the bottom of the undisturbed soil sampling barrel. Since the outer diameter of the bottom end of the soil cutting ring is smaller than the outer diameter of the top end, a conical ring structure is formed, which is easier to break the soil and is beneficial for the undisturbed soil sampling barrel to move downward in the deep soil layer. As the undisturbed soil sampling barrel and the soil cutting ring move downward, the deep soil samples enter the undisturbed soil sampling barrel. Since the soil samples entering the undisturbed soil sampling barrel are relatively complete and have no major deformation, it is convenient for researchers to study. The setting of the second clamping hole makes it convenient to insert the wrench tool and to rotate the soil cutting ring and the internal threaded sleeve, thereby facilitating the disassembly and assembly of the soil cutting ring at the bottom of the undisturbed soil sampling barrel.

[0010] Furthermore, the light-shielding soil sampling mechanism comprises an arc groove 1, an arc groove 2, an arc stop edge, a rotating shaft, an arc scraper plate, a scraper blade, a soil sample guide groove, a scraper control motor, a hollow column rotation component and a hollow column rotation locking component. The side of the sampling hollow column is provided with an arc groove 1, the side of the slide cylinder is provided with an arc groove 2, the arc groove 2 is arranged corresponding to the arc groove 1 up and down, the top inner side of the arc groove 2 is provided with an arc stop edge, and the arc One end of the second through groove is rotatably connected to a vertical rotating shaft, the part of the rotating shaft located in the second circular arc through groove is fixedly connected to one end of a circular arc scraper plate, the other end of the circular arc scraper plate is provided with a scraping blade, and a soil sample guide groove is opened on the inner side of the circular arc scraper plate, the top of the rotating shaft is fixedly connected to the output shaft of the scraping control motor, the scraping control motor is installed on the top of the slide cylinder, the top of the sampling hollow column is installed with a hollow column rotating assembly, and the hollow column rotating locking assembly is installed on the hollow column rotating assembly.

[0011] The hollow column rotation locking assembly is used to lock the hollow column rotation assembly and the connecting plate together. The hollow column rotation assembly is used to drive the sampling hollow column to rotate. When a light-shielding soil sampling mechanism is needed to take samples in deep soil, the drill rod lifting assembly first drives the hollow auger rod to move upward in the soil. At the same time, the hydraulic cylinder is quickly shortened, allowing the sampling hollow column to descend faster than the hollow auger rod. At this time, the relative height of the sampling hollow column in the soil remains unchanged, while the hollow auger rod moves upward in the soil. As a result, the bottom of the sampling hollow column extends from the bottom end of the hollow auger rod, allowing the arc through groove to be located below the bottom end of the hollow auger rod. Since the bottom end of the sliding cylinder has corresponded to the top of the undisturbed soil sampling cylinder when sampling with the help of the undisturbed soil sampling cylinder, when the bottom end of the sliding cylinder corresponds to the top of the undisturbed soil sampling cylinder, the arc The first slot coincides with the second arc slot, and the scraping control motor drives the rotating shaft to rotate counterclockwise. The rotating shaft drives the arc scraper plate to extend from the second arc slot and the first arc slot, so that the scraping blade at the end of the arc scraper plate contacts the inner wall of the soil hole made by the hollow spiral drill rod. With the help of the hollow column rotating assembly, the sampling hollow column is driven to rotate clockwise, and the scraping blade scrapes off the soil sample on the inner wall of the soil hole, and the soil sample falls into the slide cylinder along the soil sample guide groove. After the sampling hollow column rotates one circle clockwise, it stops. The hollow column rotation locking assembly locks the hollow column rotation assembly, so that the sampling hollow column can no longer rotate relative to the hollow spiral drill rod. Then the scraping control motor drives the rotating shaft to rotate clockwise, and the arc scraper plate retracts into the second arc slot, and the arc stop edge limits the arc scraper plate, so that the arc scraper plate is completely in the second arc slot and stops in time.

[0012] Furthermore, the hollow column rotation assembly includes a top plate, a locking bolt, a lever and an extended slot. The top outer peripheral side of the sampling hollow column is fixedly sleeved with the top plate, and a plurality of lever slots are provided in a circular array on the outer peripheral side of the top plate. One end of the lever is inserted into each lever slot, and an extended slot is provided at the other end of the lever. The top edge of the top plate is threadedly connected with a locking bolt at a position corresponding to the lever slot, and the locking bolt presses against the corresponding lever. The locking bolt facilitates the stable connection between the lever and the top plate, and the sampling hollow column is conveniently rotated with the help of the lever, so that the sampling hollow column can be rotated relative to the hollow spiral drill rod. If the resistance is too large to rotate the sampling hollow column, the extension rod can be inserted into the extended slot at the end of the lever, so as to facilitate the rotation of the sampling hollow column.

[0013] Furthermore, the hollow column rotation locking assembly includes a protrusion, a sliding column, a pull ring, a spring and a clamping column. The side of the top plate is fixedly connected with a protrusion, the sliding hole of the protrusion is vertically slidably connected with a sliding column, the top of the sliding column is fixedly connected with a pull ring, the bottom of the sliding column is fixedly connected with a clamping column, the column section of the sliding column between the protrusion and the clamping column is sleeved with a spring, and the top of the connecting plate is provided with a circular clamping groove that cooperates with the clamping column. The spring pushes the sliding column to descend relative to the protrusion, so that the clamping column at the bottom of the sliding column can be clamped with the circular clamping groove on the connecting plate. When the sampling hollow column needs to be rotated, the sliding column is pulled up with the help of the pull ring to overcome the elastic force of the spring, so that the clamping column is separated from the circular clamping groove, and the sampling hollow column can be rotated at this time.

[0014] Furthermore, the light-shielding soil holding mechanism includes an open light-shielding bottle and a light-shielding bottle sealing component. The open light-shielding bottle is placed in the slide cylinder, and the horizontal position of the bottle mouth at the top of the open light-shielding bottle is lower than the bottom of the second arc groove. The light-shielding bottle sealing component is installed on the top of the slide cylinder. The soil sample falls into the slide cylinder along the soil sample guide groove and finally falls into the open light-shielding bottle. The soil sample is held by the open light-shielding bottle. The light-shielding bottle sealing component seals the top of the open light-shielding bottle. When the drill rod lifting assembly drives the drill platform to rise and let the hollow spiral drill rod and the sampling hollow column return to the ground, the open light-shielding bottle can be taken away by means of the take-and-place groove on the side of the slide cylinder. Since the open light-shielding bottle is closed and light-shielded at this time, the influence of air disturbance or light on the ground on the soil sample in the open light-shielding bottle can be avoided, and a more accurate soil sample can be sampled. Among them, the bottom of the take-and-place groove is higher than the bottom of the slide cylinder, so as to prevent the open light-shielding bottle from easily escaping from the take-and-place groove inside the slide cylinder.

[0015] Furthermore, the light-shielding bottle sealing assembly includes a closed electric telescopic rod, a pressing plate, a clamping block, a rubber cover, a limit support ring and a rubber convex edge. The closed electric telescopic rod is installed at the top center of the slide tube, the telescopic end of the bottom of the closed electric telescopic rod is fixedly connected with the pressing plate, the bottom center of the pressing plate is fixedly connected with the clamping block, the clamping block is clamped with the top clamping groove of the rubber cover, the rubber cover is arranged correspondingly to the top bottle mouth of the open light-shielding bottle, and the top outer peripheral side of the rubber cover is integrally connected with the rubber convex edge, and the top inner peripheral side of the slide tube is provided with a limit support ring, and the limit support ring supports the bottom of the rubber convex edge. The rubber cover is used to close the top of the open light-shielding bottle after the soil sample is placed in the open light-shielding bottle. Before the cover is closed, the rubber cover will not fall due to gravity or vibration due to the support of the limiting support ring on the rubber convex edge and the clamping connection of the clamping block and the clamping groove. After the soil sample is placed in the open light-shielding bottle, the closed electric telescopic rod is extended, and the rubber cover is driven to descend through the pressing plate. At this time, the rubber convex edge is deformed and passes over the limiting support ring. During this process, due to the clamping connection of the clamping block and the clamping groove, the rubber cover is still stably located at the lower side of the pressing plate, and the closed electric telescopic rod continues to extend, finally allowing the rubber cover to plug the top bottle opening of the open light-shielding bottle. Then the closed electric telescopic rod is shortened, and since the friction force between the rubber cover and the open light-shielding bottle is greater than the friction force between the clamping block and the clamping groove, the clamping block is separated from the clamping groove, and the rubber cover remains on the top of the open light-shielding bottle to close the top of the open light-shielding bottle, and the rubber convex edge cooperates with the rubber cover to better seal the top bottle opening of the open light-shielding bottle.

[0016] Compared with the prior art, the soil sampling device for deep soil sampling has the following beneficial effects: 1. The drill rod lifting assembly is used to drive the hollow spiral drill rod up and down through the drilling platform. The power assembly is used to drive the hollow spiral drill rod to rotate. The hollow spiral drill rod descends during the rotation process to drill a hole on the ground. The hollow spiral drill rod is first used to drill into the soil layer to avoid the influence of stones and other debris in the upper layer of the soil. 2. The slide tube lifting assembly drives the slide tube to move upward in the undisturbed soil sampling tube until the bottom end of the slide tube corresponds to the top of the undisturbed soil sampling tube and stops. Then the hollow column lifting assembly drives the sampling hollow column to descend relative to the hollow spiral drill rod. The sampling hollow column drives the undisturbed soil sampling tube to descend. The deep undisturbed soil sample enters the undisturbed soil sampling tube. After the undisturbed soil sample fills the undisturbed soil sampling tube, the hollow column lifting assembly stops working. The sampling work of the undisturbed soil sample is realized through the undisturbed soil sampling tube. 3. The drill rod lifting assembly drives the hollow auger rod to move up in the soil. At the same time, the hydraulic cylinder shortens rapidly, allowing the sampling hollow column to descend faster than the hollow auger rod. At this time, the relative height of the sampling hollow column in the soil remains unchanged, and the hollow auger rod moves up in the soil. As a result, the bottom of the sampling hollow column extends from the bottom end of the hollow auger rod, allowing the arc through groove to be located below the bottom end of the hollow auger rod. At this time, the light-shielding soil sampling mechanism and the light-shielding soil holding mechanism cooperate to complete the relatively closed collection and sampling of deep soil samples underground, thereby improving the accuracy of deep soil sample collection and avoiding excessive influence on the soil samples when they are placed above the ground.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 13 The present embodiment provides a technical solution: a soil sampling device for deep soil sampling, comprising a soil deep drilling mechanism 2, the soil deep drilling mechanism 2 comprising a drill rod lifting assembly, a drill platform 27, a drill rod bearing 28 and a hollow spiral drill rod 29, the drill rod lifting assembly is equipped with a drill platform 27, the middle part of the drill platform 27 is rotatably connected to the top of the hollow spiral drill rod 29 through the drill rod bearing 28, and the top of the hollow spiral drill rod 29 is connected to a power assembly; The drill rod lifting assembly includes a mounting frame 21, a column 22, a lead screw 23, a lifting control motor 24, a lead screw nut 25, a lifting plate 26, and a vehicle body mounting plate 213. The mounting frame 21 is fixedly connected to the column 2, and the mounting frame 21 is rotatably connected to the vertical lead screw 23 through a bearing. The side of the drilling platform 27 is fixedly connected to the lifting plate 26, and the lead screw nut 25 is embedded and installed on the lifting plate 26. The lead screw nut 25 is matched with the lead screw 23. The guide hole on the lifting plate 26 is slidably connected to the column 22, and the top of the lead screw 23 is fixedly connected to the output shaft of the lifting control motor 24. The control motor 24 is installed on the top of the mounting frame 21, and two vehicle body mounting plates 213 are fixedly connected to the side of the mounting frame 21. The two vehicle body mounting plates 213 can be installed on sampling vehicles such as engineering vehicles and pickup trucks with the help of mounting bolts. The lifting control motor 24 drives the lead screw 23 to rotate clockwise, and the threaded action of the lead screw 23 and the lead screw nut 25 drives the lifting plate 26 to descend along the column 22, thereby driving the drilling platform 27 and the hollow spiral drill rod 29 to descend. The lifting control motor 24 drives the lead screw 23 to rotate counterclockwise, which can drive the drilling platform 27 and the hollow spiral drill rod 29 to rise.

[0020] The power assembly includes a driven gear 210, a drilling motor 211, and a driving gear 212. The top of the hollow spiral drill rod 29 is fixedly sleeved with the driven gear 210, and the drilling motor 211 is installed on the drilling platform 27. The output shaft of the drilling motor 211 is fixedly connected with the driving gear 212, and the driving gear 212 is meshed with the driven gear 210. When the drilling motor 211 works, the hollow spiral drill rod 29 is driven to rotate through the transmission of the driving gear 212 and the driven gear 210.

[0021] It also includes a non-disturbance soil sampling mechanism 3, a light-shielding soil sampling mechanism 4 and a light-shielding soil containing mechanism 5; The undisturbed soil sampling mechanism 3 comprises a sampling hollow column 31, a undisturbed soil sampling tube 35, a slide tube 310, a cone 311, a clamping hole 312, a take-and-put through slot 316, a hollow column lifting assembly, a slide tube lifting assembly and a soil cutting deep assembly. The sampling hollow column 31 is inserted into the hollow spiral drill rod 29, the top of the sampling hollow column 31 is connected to the hollow column lifting assembly, and the bottom of the sampling hollow column 31 is threadedly connected to the undisturbed soil sampling tube 35. The top of the undisturbed soil sampling cylinder 35 is connected to a soil cutting component at the bottom end, a clamping hole 312 is provided on the outside of the undisturbed soil sampling cylinder 35, a slide cylinder 310 is vertically slidably installed in the undisturbed soil sampling cylinder 35, the upper and lower ends of the slide cylinder 310 are both closed, and the top of the slide cylinder 310 is connected to a slide cylinder lifting component, the bottom end of the slide cylinder 310 is integrally formed with a cone 311, and a take-in and put-out slot 316 is provided on the side of the slide cylinder 310; The hollow column lifting assembly includes a hydraulic cylinder 32, a connecting plate 33 and a hollow column bearing 34. The top of the sampling hollow column 31 is rotatably connected to one end of the connecting plate 33 through the hollow column bearing 34. The bottom of the other end of the connecting plate 33 is fixedly connected to the top of the hydraulic cylinder 32. The bottom of the hydraulic cylinder 32 is fixedly connected to the top of the drilling platform 27. When the hydraulic cylinder 32 is shortened, the sampling hollow column 31 is driven to descend relative to the hollow auger rod 29 through the connecting plate 33. When the hydraulic cylinder 32 is extended, the sampling hollow column 31 is driven to rise relative to the hollow auger rod 29 through the connecting plate 33. The setting of the hollow column bearing 34 allows the sampling hollow column 31 to rotate relative to the hollow auger rod 29.

[0022] The slide tube lifting assembly includes an inner fixed frame 37, an electric lifting telescopic rod 38 and an arch frame 39. The top of the slide tube 310 is fixedly connected to the arch frame 39. The top of the arch frame 39 is fixedly connected to the bottom of the electric lifting telescopic rod 38. The top of the electric lifting telescopic rod 38 is installed on the inner wall of the sampling hollow column 31 through the inner fixed frame 37. The inner fixed frame 37 is used to install the electric lifting telescopic rod 38. When the electric lifting telescopic rod 38 is extended or shortened, it can drive the slide tube 310 to move up and down relative to the undisturbed soil sampling tube 35 by driving the arch frame 39.

[0023] The soil cutting and penetration component includes a soil cutting ring 36, an internal threaded sleeve 313 and a second clamping hole 314. The inner diameter of the soil cutting ring 36 is the same as the inner diameter of the undisturbed soil sampling tube 35, and the outer diameter of the bottom end of the soil cutting ring 36 is smaller than the outer diameter of the top end. The top of the soil cutting ring 36 is integrally formed with the internal threaded sleeve 313, and the outer side of the internal threaded sleeve 313 is provided with a second clamping hole 314. The internal threaded sleeve 313 is threadedly connected to the bottom end of the undisturbed soil sampling tube 35. The internal threaded sleeve 313 facilitates the installation of the soil cutting ring 36 at the bottom of the undisturbed soil sampling barrel 35. Since the outer diameter of the bottom end of the soil cutting ring 36 is smaller than the outer diameter of the top end, a conical ring structure is formed, which is easier to break the soil and facilitates the downward movement of the undisturbed soil sampling barrel 35 in the deep soil layer. As the undisturbed soil sampling barrel 35 and the soil cutting ring 36 move downward, the deep soil samples enter the undisturbed soil sampling barrel 35. Since the soil samples entering the undisturbed soil sampling barrel 35 are relatively complete and have no major deformation, it is convenient for researchers to study. The setting of the second clamping hole 314 facilitates the insertion of the wrench tool and the rotation of the soil cutting ring 36 and the internal threaded sleeve 313, thereby facilitating the disassembly and assembly of the soil cutting ring 36 at the bottom of the undisturbed soil sampling barrel 35.

[0024] The soil cutting and penetrating assembly further includes a gap retaining ring 315, and the outer peripheral side of the top of the soil cutting ring 36 is integrally connected with the gap retaining ring 315. The upper side of the gap retaining ring 315 is in close contact with the ground of the hollow auger rod 29, and the outer diameter of the gap retaining ring 315 is smaller than the outer diameter of the bottom end of the hollow auger rod 29. The gap retaining ring 315 is used to block the bottom of the gap between the hollow auger rod 29 and the sampling hollow column 31, so as to prevent the soil from entering between the hollow auger rod 29 and the sampling hollow column 31 when the hollow auger rod 29 and the sampling hollow column 31 move downward in the soil layer.

[0025] Specifically, the upper and lower ends of the undisturbed soil sampling tube 35 are respectively provided with external threaded sleeves, the external threaded sleeve at the lower end of the undisturbed soil sampling tube 35 is threadedly connected to the internal threaded sleeve 313, and the external threaded sleeve at the upper end of the undisturbed soil sampling tube 35 is threadedly connected to the inner side of the bottom end of the sampling hollow column 31; The undisturbed soil sampling barrel 35 is composed of a semi-circular plate 351, a positioning hole 352, and a positioning column 353. There are two semi-circular plates 351, and three positioning columns 353 are equidistantly arranged on one side of each semi-circular plate 351. Three positioning holes 352 are equidistantly opened on the other side of each semi-circular plate 351. The two semi-circular plates 351 cooperate with the positioning holes 352 and the positioning columns 353 to form the main body of the undisturbed soil sampling barrel 35. The external threaded sleeves at the upper and lower ends of the undisturbed soil sampling barrel 35 can be divided into two halves along with the two semi-circular plates 351.

[0026] Since the two semicircular arc plates 351 can be separated, the undisturbed soil sample in the undisturbed soil sampling tube 35 can be taken out more easily, thereby avoiding deformation of the soil sample when the soil sample is poked out from one end of the undisturbed soil sampling tube 35 .

[0027] The light-shielding soil sampling mechanism 4 is installed on the slide 310 and the sampling hollow column 31; The shading soil containing mechanism 5 is installed in the slide cylinder 310 .

[0028] When in use, the drill rod lifting assembly is installed on a sampling vehicle such as an engineering vehicle or a pickup truck. The drill rod lifting assembly is used to drive the hollow auger rod 29 to move up and down through the drilling platform 27. The power assembly is used to drive the hollow auger rod 29 to rotate. The hollow auger rod 29 descends during the rotation process to drill a hole on the ground and bring the soil below the ground to the ground. As the hollow auger rod 29 drills into the soil layer, the bottom end of the sampling hollow column 31 in the undisturbed soil sampling mechanism 3 and the undisturbed soil sampling cylinder 35 also enter the soil layer. During this process, The bottom end of the slide cylinder 310 closes the bottom end of the undisturbed soil sampling cylinder 35, and the cone 311 promotes the soil at the bottom center of the hollow auger rod 29 to move around, and is finally carried upward by the threads of the hollow auger rod 29. After the hollow auger rod 29 penetrates to the required depth, the drill rod lifting assembly and the power assembly stop working, and the slide cylinder lifting assembly drives the slide cylinder 310 to move upward in the undisturbed soil sampling cylinder 35 until the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35, and then the hollow column lifting assembly drives the sampling hollow The column 31 descends relative to the hollow auger rod 29, and the sampling hollow column 31 drives the undisturbed soil sampling tube 35 to descend, and the deep undisturbed soil sample enters the undisturbed soil sampling tube 35. After the undisturbed soil sample fills the undisturbed soil sampling tube 35, the hollow column lifting assembly stops working, and the sampling of the undisturbed soil sample is achieved through the undisturbed soil sampling tube 35. The setting of the clamping hole 312 is convenient for installing the wrench tool and rotating the undisturbed soil sampling tube 35, so as to facilitate the undisturbed soil sampling tube 35 at the bottom of the sampling hollow column 31. The disassembly and assembly, and the setting of the soil-cutting deep component facilitate the bottom of the undisturbed soil sampling tube 35 to break the soil, allowing the undisturbed soil sampling tube 35 to descend more easily in the deep soil, allowing the deep soil to enter the undisturbed soil sampling tube 35, and the shading soil sampling mechanism 4 can rotate with the sampling hollow column 31 to allow the deep soil sample to enter the shading soil holding mechanism 5. The soil sample is sealed in the deep soil position through the shading soil holding mechanism 5, avoiding the soil sample being affected by being placed above the ground, and reducing the impact of excessive air or sunlight on the soil sample on the ground.

[0029] For example 2, please refer to Figures 1 to 13 , This embodiment provides a technical solution: a soil sampling device for deep soil sampling. This embodiment is a further explanation of the structure of the first embodiment; The light-shielding soil sampling mechanism 4 includes an arc groove 1 41, an arc groove 2 42, an arc stop 43, a rotating shaft 44, an arc scraper plate 45, a scraper blade 46, a soil sample guide groove 47, a scraper control motor 48, a hollow column rotating assembly and a hollow column rotating locking assembly. The side of the sampling hollow column 31 is provided with an arc groove 1 41, and the side of the slide cylinder 310 is provided with an arc groove 2 42. The arc groove 2 42 is arranged corresponding to the arc groove 1 41 up and down, and the top inner side of the arc groove 2 42 is provided with an arc stop 43. The arc groove 2 One end of the shaft 42 is rotatably connected to a vertical shaft 44, and the part of the shaft 44 located in the arc groove 42 is fixedly connected to one end of an arc scraper plate 45, and the other end of the arc scraper plate 45 is provided with a scraping blade 46, and the inner side of the arc scraper plate 45 is provided with a soil sample guide groove 47, and the top of the shaft 44 is fixedly connected to the output shaft of a scraper control motor 48, and the scraper control motor 48 is installed on the top of the slide 310, and a hollow column rotating assembly is installed on the top of the sampling hollow column 31, and a hollow column rotating locking assembly is installed on the hollow column rotating assembly.

[0030] The hollow column rotation locking assembly is used to lock the hollow column rotation assembly and the connecting plate 33 together. The hollow column rotation assembly is used to drive the sampling hollow column 31 to rotate. When the light-shielding soil sampling mechanism 4 is used to sample in deep soil, the drill rod lifting assembly first drives the hollow auger rod 29 to move upward in the soil. At the same time, the hydraulic cylinder 32 is quickly shortened to allow the sampling hollow column 31 to descend faster than the hollow auger rod 29. At this time, the sampling hollow column 31 is in the soil. The relative height remains unchanged, while the hollow auger rod 29 moves upward in the soil, thereby, the bottom of the sampling hollow column 31 extends from the bottom end of the hollow auger rod 29, so that the arc through groove 1 41 is located below the bottom end of the hollow auger rod 29. Since the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35 when sampling with the aid of the undisturbed soil sampling cylinder 35, when the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35, the arc through groove 1 41 and the arc The second through groove 42 overlaps and corresponds, and the scraping control motor 48 drives the rotating shaft 44 to rotate counterclockwise. The rotating shaft 44 drives the arc scraping plate 45 to extend from the arc through groove 2 42 and the arc through groove 1 41, so that the scraping blade 46 at the end of the arc scraping plate 45 contacts the inner wall of the soil hole made by the hollow spiral drill rod 29. With the help of the hollow column rotating assembly, the sampling hollow column 31 is driven to rotate clockwise, and the scraping blade 46 scrapes off the soil sample on the inner wall of the soil hole, and the soil sample falls into the slide along the soil sample guide groove 47. 310, after the sampling hollow column 31 rotates one circle clockwise, it stops, and the hollow column rotation locking assembly locks the hollow column rotation assembly, so that the sampling hollow column 31 can no longer rotate relative to the hollow spiral drill rod 29, and then the scraping control motor 48 works to drive the rotating shaft 44 to rotate clockwise, and the arc scraper plate 45 retracts into the arc groove 2 42, and the arc stop edge 43 limits the arc scraper plate 45, so that the arc scraper plate 45 is completely in the arc groove 2 42 and stops in time.

[0031] The hollow column rotating assembly includes a top plate 49, a locking bolt 410, a lever 411 and an extended slot 412. The top outer peripheral side of the sampling hollow column 31 is fixedly sleeved with the top plate 49. The outer peripheral side of the top plate 49 is provided with a plurality of lever slots in an annular array. Specifically, there are three lever slots. One end of the lever 411 is inserted in each lever slot. The other end of the lever 411 is provided with an extended slot 412. The top edge of the top plate 49 is threadedly connected with a locking bolt 410 at a position corresponding to the lever slot. The locking bolt 410 is pressed against the corresponding lever 411. The locking bolt 410 facilitates the stable connection between the lever 411 and the top plate 49. With the help of the lever 411, the sampling hollow column 31 is conveniently rotated so that the sampling hollow column 31 can be rotated relative to the hollow spiral drill rod 29. If the resistance is too large and the sampling hollow column 31 cannot be rotated, the extension rod can be inserted into the extended slot 412 at the end of the lever 411, so as to facilitate the rotation of the sampling hollow column 31.

[0032] The hollow column rotation locking assembly includes a protrusion 413, a sliding column 414, a pull ring 415, a spring 416 and a clamping column 417. The protrusion 413 is fixedly connected to the side of the top plate 49, the sliding column 414 is vertically slidably connected in the sliding hole of the protrusion 413, the top of the sliding column 414 is fixedly connected to the pull ring 415, the bottom of the sliding column 414 is fixedly connected to the clamping column 417, the column section of the sliding column 414 between the protrusion 413 and the clamping column 417 is sleeved with a spring 416, and the top of the connecting plate 33 is provided with a circular groove that cooperates with the clamping column 417. The spring 416 pushes the slide post 414 to drop relative to the protrusion 413, so that the clamping column 417 at the bottom of the slide post 414 can be clamped with the circular groove on the connecting plate 33. When the sampling hollow column 31 needs to be rotated, the slide post 414 is pulled up with the help of the pull ring 415 to overcome the elastic force of the spring 416 and allow the clamping column 417 to disengage from the circular groove. At this time, the sampling hollow column 31 can be rotated.

[0033] For example 3, please refer to Figures 1 to 13 , This embodiment provides a technical solution: a soil sampling device for deep soil sampling. This embodiment is a further explanation of the structure of the second embodiment; The light-shielding soil containing mechanism 5 comprises an open light-shielding bottle 51 and a light-shielding bottle sealing assembly. The open light-shielding bottle 51 is placed in the slide 310. The horizontal position of the top bottle mouth of the open light-shielding bottle 51 is lower than the bottom of the arc through groove 42. The light-shielding bottle sealing assembly is installed on the top of the slide 310. The soil sample falls into the slide 310 along the soil sample guide groove 47 and finally falls into the open light-shielding bottle 51. The soil sample is held by the open light-shielding bottle 51, and the light-shielding bottle closing assembly closes the top of the open light-shielding bottle 51. When the drill rod lifting assembly drives the drilling platform 27 to rise and let the hollow spiral drill rod 29 and the sampling hollow column 31 return to the ground, the open light-shielding bottle 51 can be taken away with the help of the taking and placing groove 316 on the side of the slide 310. Since the open light-shielding bottle 51 is closed and light-shielded at this time, the influence of air disturbance or light on the ground on the soil sample in the open light-shielding bottle 51 can be avoided, and a more accurate soil sample can be sampled. Among them, the bottom of the taking and placing groove 316 is higher than the bottom of the slide 310, which prevents the open light-shielding bottle 51 from easily escaping from the taking and placing groove 316 from the inside of the slide 310.

[0034] The light-shielding bottle sealing assembly includes a closed electric telescopic rod 52, a pressing plate 53, a clamping block 54, a rubber cover 55, a limit support ring 56 and a rubber convex edge 57. The closed electric telescopic rod 52 is installed at the top center of the slide 310, and the telescopic end at the bottom of the closed electric telescopic rod 52 is fixedly connected with the pressing plate 53. The bottom center of the pressing plate 53 is fixedly connected with the clamping block 54, and the clamping block 54 is clamped with the top clamping groove of the rubber cover 55. The rubber cover 55 is arranged corresponding to the top bottle mouth of the open light-shielding bottle 51, and the top outer peripheral side of the rubber cover 55 is integrally formed with a rubber convex edge 57. A limit support ring 56 is arranged on the top inner peripheral side of the slide 310, and the limit support ring 56 supports the bottom of the rubber convex edge 57. The rubber cover 55 is used to close the top of the open light-shielding bottle 51 after the soil sample is placed in the open light-shielding bottle 51. Before the cover is closed, the rubber cover 55 will not fall due to gravity or vibration due to the support of the limit ring 56 on the rubber convex edge 57 and the clamping of the clamping block 54 and the clamping groove. After the soil sample is placed in the open light-shielding bottle 51, the closed electric telescopic rod 52 is extended, and the rubber cover 55 is driven to descend through the pressing plate 53. At this time, the rubber convex edge 57 is deformed and passes over the limit ring 56. In this process, due to the clamping of the clamping block 54 and the clamping groove, the rubber cover 5 5 is still stably located at the lower side of the pressing plate 53, the closed electric telescopic rod 52 continues to extend, and finally the rubber cover 55 blocks the top bottle mouth of the open light-shielding bottle 51, and then the closed electric telescopic rod 52 is shortened. Since the friction force between the rubber cover 55 and the open light-shielding bottle 51 is greater than the friction force between the clamping block 54 and the clamping groove, the clamping block 54 is separated from the clamping groove, and the rubber cover 55 remains on the top of the open light-shielding bottle 51 to seal the top of the open light-shielding bottle 51. The rubber convex edge 57 cooperates with the rubber cover 55 to better seal the top bottle mouth of the open light-shielding bottle 51.

[0035] For other embodiments, see Figure 1 and 2 , also includes a drill rod protection mechanism 1, the drill rod protection mechanism 1 includes a fixed ear seat 11, a disassembly ear seat 12, a disassembly bolt 13, and a protective cover 14. Two fixed ear seats 11 are respectively arranged on both sides of the mounting frame 21, and disassembly ear seats 12 are also arranged on both sides of the protective cover 14 corresponding to the positions of the fixed ear seats 11. The disassembly ear seats 12 are fixedly connected to the corresponding fixed ear seats 11 by disassembly bolts 13. The protective cover 14 is installed with the help of the fixed ear seats 11, the disassembly ear seats 12 and the disassembly bolts 13. The protective cover 14 is used to protect the hollow auger rod 29 to prevent the hollow auger rod 29 from being damaged by collision during transfer and transportation, and to prevent the hollow auger rod 29 from injuring surrounding operators when rotating. When the drill rod lifting assembly drives the hollow auger rod 29 to rise to the highest position, the bottom end of the hollow auger rod 29 is flush with the bottom of the protective cover 14.

[0036] See also Figures 1 to 13 , a sampling method of a soil sampling device for deep soil sampling, comprising the following steps: Step 1: Install the drill rod lifting assembly on the sampling vehicle, the power assembly drives the hollow auger rod 29 to rotate, the drill rod lifting assembly drives the hollow auger rod 29 to move downward through the drilling platform 27, and the hollow auger rod 29 descends to the ground to drill a hole downward during the rotation process; Step 2: As the hollow auger rod 29 drills into the soil layer, the bottom end of the sampling hollow column 31 and the undisturbed soil sampling cylinder 35 in the undisturbed soil sampling mechanism 3 also enter the soil layer. During this process, the bottom end of the slide cylinder 310 seals the bottom end of the undisturbed soil sampling cylinder 35, and the cone 311 promotes the soil at the bottom center of the hollow auger rod 29 to move around, and is finally carried upward by the thread of the hollow auger rod 29; Step three, after the hollow auger rod 29 penetrates to the required depth, the drill rod lifting assembly and the power assembly stop working, the slide cylinder lifting assembly drives the slide cylinder 310 to move upward in the undisturbed soil sampling cylinder 35, and stops when the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35, and then the hollow column lifting assembly drives the sampling hollow column 31 to descend relative to the hollow auger rod 29, and the sampling hollow column 31 drives the undisturbed soil sampling cylinder 35 to descend, and the deep undisturbed soil sample enters the undisturbed soil sampling cylinder 35. After the undisturbed soil sample fills the undisturbed soil sampling cylinder 35, the hollow column lifting assembly stops working, and the sampling of the undisturbed soil sample is realized through the undisturbed soil sampling cylinder 35; Step 4: the drill rod lifting assembly drives the hollow auger rod 29 to move upward in the soil, and the hydraulic cylinder 32 is shortened to ensure that the relative height of the sampling hollow column 31 in the soil remains unchanged. The hollow auger rod 29 moves upward in the soil, and the bottom of the sampling hollow column 31 extends from the bottom end of the hollow auger rod 29, so that the arc groove 1 41 is located below the bottom end of the hollow auger rod 29. Since the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35 when sampling with the aid of the undisturbed soil sampling cylinder 35, when the bottom end of the slide cylinder 310 corresponds to the top of the undisturbed soil sampling cylinder 35, the arc groove 1 41 coincides with the arc groove 2 42; Step 5: The scraping control motor 48 drives the rotating shaft 44 to rotate counterclockwise, and the rotating shaft 44 drives the arc scraping plate 45 to extend from the arc slot 2 42 and the arc slot 1 41, so that the scraping blade 46 at the end of the arc scraping plate 45 contacts the inner wall of the soil hole made by the hollow spiral drill rod 29, and the sampling hollow column 31 is driven to rotate clockwise by the hollow column rotating assembly, and the scraping blade 46 scrapes the soil sample on the inner wall of the soil hole, and the soil sample falls into the slide cylinder 310 along the soil sample guide groove 47, and the sampling hollow column 31 stops after rotating one circle clockwise; Step six, the soil sample falls into the slide cylinder 310 along the soil sample guide groove 47 and finally falls into the open light-shielding bottle 51. The open light-shielding bottle 51 is used to hold the soil sample, and the closed electric telescopic rod 52 is extended, and the rubber cover 55 is driven down by the pressing plate 53. At this time, the rubber convex edge 57 is deformed and passes over the limit support ring 56. In this process, due to the engagement of the clamping block 54 with the clamping groove, the rubber cover 55 is still stably on the lower side of the pressing plate 53, and the closed electric telescopic rod 52 continues to extend, and finally the rubber cover 55 blocks the top bottle mouth of the open light-shielding bottle 51, and then the closed electric telescopic rod 52 is shortened. Since the friction force between the rubber cover 55 and the open light-shielding bottle 51 is greater than the friction force between the clamping block 54 and the clamping groove, the clamping block 54 is separated from the clamping groove, and the rubber cover 55 remains on the top of the open light-shielding bottle 51 to seal the top of the open light-shielding bottle 51.
