[0002] The collection of geographic information for national land space planning is a process of using a variety of advanced technical means to obtain all kinds of geographic information data for national land space in an all-round way. Among them, soil, as a key component of national land space, has characteristics such as type, texture, fertility and carrying capacity, which are of great significance to many aspects of national land space planning. In agricultural land planning, it determines the suitable planting area and variety selection of crops; in terms of ecological protection, it is related to the suitability of habitats for rare species and the maintenance of ecosystem functions; for the layout of construction land, it affects the stability of building foundations and the feasibility of development. In order to lay a solid foundation for the scientific and reasonable implementation of national land space planning, soil collection is required for national land space planning.

[0003] The ring knife soil sampler is one of the most commonly used soil sampling tools at present. Its operation process is as follows: first manually drill the ring knife soil sampler into the soil until it reaches the predetermined depth, then carefully pull it out, then remove the ring knife and the matching semi-cylinder. At this time, the soil remaining in the ring knife can be used as a test sample. However, during the use of this traditional soil sampler, each link relies on manual operation, which not only consumes a lot of time, but also requires the operator to exert a lot of physical strength, and the efficiency needs to be improved urgently.

[0004] After searching, it was found that an automatic soil sampler is disclosed in the announcement number: CN113405837B, which includes a cart, on which is provided a soil-breaking device for removing the surface soil layer, a soil-taking device for taking out soil samples, and a driving device for driving the soil-breaking device and the soil-taking device to move downward; the cart includes a base plate, a rotating disk rotatably connected to the upper side of the base plate, a rotating shaft rotatably connected to the middle of the rotating disk, the rotating shaft is fixedly connected to the base plate, two fixed frames are arranged at intervals on the outer side of the upper side of the rotating disk, the fixed frame is connected to a sliding frame along the vertical sliding connection, and the sliding frame is connected to an insert block on the side facing the axis of the rotating shaft; the soil-breaking device and the soil-taking device are respectively mounted on the two sliding frames; the driving device includes a driving cylinder and a driving block connected to the driving cylinder, and a slot for the insert block to be inserted is arranged on one side of the driving block.

[0009] Preferably, the rotating assembly further comprises a protruding layer and a limiting layer, the outer wall of the protruding layer is fixedly connected to the shaft of the mounting seat, and one end of the limiting layer is fixedly connected to the outer wall of the mounting frame.

[0010] Preferably, an opening is provided on the surface of the vehicle body, an annular mounting piece is fixedly connected to the inside of the opening, a plurality of guide frames distributed in an annular shape are provided on the outside of the opening, and the bottom end of the guide frame is fixedly connected to the upper surface of the vehicle body.

[0011] Preferably, an insertion rod is provided through the surface of the mounting member, the outer side wall of the insertion rod is connected to a rod member via an axis rotation, the top end of the rod member is connected to an inclined plate via an axis rotation, the top end of the inclined plate is connected to a fixed plate via an axis rotation, and the bottom end of the fixed plate is fixedly connected to the upper surface of the mounting member.

[0012] Preferably, a spring 1 is sleeved on the outer wall of the insertion rod, and the spring 1 is located above the mounting piece.

[0013] Preferably, a second spring is arranged inside the piston cylinder, and a notch is opened on one side of the piston cylinder.

[0014] Preferably, the sample arrangement assembly also includes a U-shaped sliding member, the bottom end of the sliding member is slidably connected to the upper surface of the vehicle body, the upper surface of the vehicle body is fixedly connected to a driving motor, the driving end of the driving motor is fixedly connected to a lead screw, the other end of the lead screw is rotatably connected to the upper surface of the vehicle body, and the outer wall of the lead screw penetrates and is threadedly connected to the lower side wall of the sliding member.

[0015] Preferably, a trapezoidal support layer is fixedly connected to the interior of the sliding member, and an L-shaped pushing rod is fixedly connected to the lower side wall of the sliding member.

[0016] Preferably, the sample arrangement assembly also includes a semi-circular collecting plate and a supporting plate, the top end of the collecting plate is rotatably connected to the outer wall of the sliding member via a torsion spring shaft, the bottom end of the supporting plate is fixedly connected to the upper surface of the vehicle body, and extension layers are fixedly connected to both sides of the collecting plate.

[0017] Working principle: When it is necessary to collect soil information for national land space planning, push the vehicle body to the sampling point, start the electric slide and sampling motor, the sampling motor drives the sampling barrel to rotate, the sampling barrel drives the coring drill to rotate and break the soil, and the electric slide drives the sampler to gradually rotate deep into the ground, and collect the soil inside the sampling barrel. After the sampling is completed, the electric slide runs in reverse to control the sampling barrel to rise out of the ground, completing the collection of soil information for national land space planning.

[0018] The sampling tube passes through the guide frame when it descends, so that the sampling tube is vertically limited by the guide frame to prevent the sampling tube from deflecting during sampling. The sampling motor is not operated until the sampling tube passes through the guide frame to prevent the sampling tube from shaking when rotating and being unable to pass through the guide frame. At the same time, the guide frame with an inclined upper end helps the device to be tilted, and the coring drill bit can also slide through the guide frame along the inclined upper end of the guide frame. Then the coring drill bit passes through the opening and the mounting piece and is inserted into the soil. The coring drill bit passes through the mounting piece, and the inclined plate is pushed to rotate by the coring drill bit. The rotation of the inclined plate pushes the insertion rod down through the rod and is inserted into the soil, which helps to maintain the stability of the device during sampling.

[0019] After the sampling is completed, the electric slide drives the mounting frame to rise until the extrusion rod touches the limit seat and moves downward, and the extrusion rod drives the sampler to rotate to a horizontal state when it moves downward, so that the sampling tube can rotate horizontally automatically, which is convenient for taking out the soil sample and receiving the discharged soil sample later. Then the driving motor is operated to drive the lead screw to rotate, so that the sliding part gradually moves toward the sampling tube, and the supporting layer moves to the bottom of the sampling tube to support the sampling tube, which is beneficial to maintain the stability of the sampling tube. When the sliding part moves, it drives the pushing rod to insert into the interior of the piston tube and push the piston plate 2 to move, thereby gradually squeezing the gas inside the piston tube through the pipeline and transporting it to the interior of the sampling tube, and the gas gradually pushes the piston plate 1 to move toward the mouth of the sampling tube, and gradually and automatically pushes the soil sample out, so as to realize the automatic discharge of the soil sample.

[0020] Initially, the collecting plate is kept vertical by gravity, thereby reducing the overall volume of the device. When the sliding part moves toward the sampling tube, the collecting plate moves synchronously, and when the supporting plate blocks the extension layer, the collecting plate automatically rotates to a horizontal state when passing through the supporting plate, so that the soil samples discharged from the sampling tube can be temporarily stored, making it convenient for the collectors to process the soil samples.

[0021] The present invention provides a device for automatically collecting geographic information of national land space planning. It has the following beneficial effects: 1. The present invention uses an electric slide to cooperate with a sampler to take out a cylindrical soil sample, and when the sampler rises, the sampling tube is driven to rotate horizontally through a rotating assembly. The sample inside the sampling tube can be gradually removed through the cooperation of a sample arrangement assembly and a piston plate, thereby realizing automatic discharge of the soil sample. There is no need to disassemble the sampler for sampling, reducing manual operations, realizing automated soil sample sampling and arrangement, facilitating collection personnel to collect soil samples of different depths and layers, and improving the accuracy, convenience and diversity of soil information collection for national land space planning.

[0022] 2. The present invention guides and limits the descending sampling tube through the guide frame to prevent the sampling tube from deflecting and affecting the sampling during sampling. When the sampler descends, it drives the insertion rod to be inserted into the soil, which helps to improve the stability of the sampler during sampling.

[0023] 3. The present invention supports the sampling tube horizontally through the support layer to prevent the sampling tube from shaking during sampling, which affects the collectors' taking of soil samples. The soil samples gradually squeezed out of the sampling tube can be temporarily stored through the collecting plate, which is convenient for the collectors to select and preserve samples.

[0024] 4. The present invention squeezes piston plate 2 by pushing the rod, so that the gas in the piston cylinder enters the interior of the sampling cylinder, and then piston plate 1 gradually pushes the sample inside the sampling cylinder out of the sampling cylinder, and realizes automatic cleaning of the interior of the sampling cylinder, which is beneficial to reduce the residue of soil samples.

The upper surface of the vehicle body 1 is provided with a sample arrangement component 8, and the sample arrangement component 8 includes a piston cylinder 801, and the bottom end of the piston cylinder 801 is fixedly connected to the upper surface of the vehicle body 1. A piston plate 802 is slidably provided inside the piston cylinder 801. One side of the piston cylinder 801 is connected to the air inlet end 7 through a pipeline, and the pipeline is used for gas transportation.

The highest rising point of the electric slide 2 is fixed, and under theoretical conditions, the sampler 4 can be driven to rotate to a horizontal position, and the descending point of the electric slide 2 can be flexibly adjusted according to the sampling depth, so as to facilitate the collection of soil samples at different depths.

[0029] Specifically, the electric slide 2 is used to adjust the height of the sampler 4, the sampler 4 is used to rotate and punch holes on the ground for sampling, the mounting frame 3 is used to rotate and support the mounting seat 41, the sampling tube 42 is used to store soil samples, and the guide column 54 is used to limit the moving direction of the pull rope 53.

At this time, by pushing the piston plate 2 802 to move to the other side of the piston tube 801, the gas inside the piston tube 801 is squeezed into the interior of the sampling tube 42, thereby pushing the piston plate 1 6 to move toward the tube mouth of the sampling tube 42, and then the soil sample inside the sampling tube 42 is squeezed out horizontally, realizing the rapid discharge of the sample, so that the sample can be easily taken out without disassembling the sampler 4.

[0030] Please see attached Figure 5 A sampling motor 43 is fixedly connected to the upper surface of the mounting seat 41, and a connecting layer 44 is fixedly connected to the upper inner wall of the sampling tube 42. The driving end of the sampling motor 43 passes through the mounting seat 41 and is fixedly connected to the upper surface of the connecting layer 44. A vent 45 is provided on the surface of the connecting layer 44. A coring drill bit 46 is fixedly connected to the bottom end of the sampling tube 42. A mechanical sealing structure is fixedly provided at the intersection of the mounting seat 41 and the sampling tube 42 for sealing the connection between the mounting seat 41 and the sampling tube 42 to prevent air leakage. A packing seal or a mechanical sealing structure is fixedly provided at the intersection of the mounting seat 41 and the driving end of the sampling motor 43 for sealing the intersection of the mounting seat 41 and the driving end of the sampling motor 43 to prevent air leakage. The packing seal and the mechanical sealing structure belong to the prior art and will not be described herein. The control module is electrically connected to the sampling motor 43 for controlling the sampling motor 43.

[0031] Specifically, the mounting seat 41 is used to fix the sampling motor 43, the sampling motor 43 is used to drive the connecting layer 44 to rotate, the connecting layer 44 rotates to drive the sampling tube 42 to rotate, the sampling tube 42 rotates to drive the coring drill bit 46 to rotate, the coring drill bit 46 is used to drill cylindrical soil samples, and the vent 45 is used to maintain the circulation of the internal space of the sampling tube 42.

[0032] Please see attached Figure 4 The rotating assembly 5 further includes a protruding layer 55 and a limiting layer 56 . The outer wall of the protruding layer 55 is fixedly connected to the shaft of the mounting seat 41 , and one end of the limiting layer 56 is fixedly connected to the outer wall of the mounting frame 3 .

[0033] Specifically, when the sampler 4 is vertical, the raised layer 55 and the limiting layer 56 are staggered, and when the sampler 4 rotates horizontally, the limiting layer 56 blocks and limits the raised layer 55 that rotates with the sampler 4 to prevent the sampling tube 42 from rotating excessively.

[0034] Please see attached Figure 3 -Attached Figure 7 An opening 9 is provided on the surface of the vehicle body 1, and an annular mounting member 10 is fixedly connected to the inside of the opening 9. A plurality of guide frames 11 distributed in an annular shape are provided on the outside of the opening 9. The bottom end of the guide frame 11 is fixedly connected to the upper surface of the vehicle body 1. An insertion rod 12 is provided through the surface of the mounting member 10. The outer wall of the insertion rod 12 is connected to a rod 13 through an axis rotation. The top end of the rod 13 is connected to an inclined plate 14 through an axis rotation. The top end of the inclined plate 14 is connected to a fixed plate 15 through an axis rotation. The bottom end of the fixed plate 15 is fixedly connected to the upper surface of the mounting member 10. A spring 16 is sleeved on the outer wall of the insertion rod 12. The spring 16 is located above the mounting member 10.

[0035] Specifically, the opening 9 is used for the sampler 4 to pass through, and the guide frame 11 is composed of an inclined section on the upper side, a vertical section on the middle side, and a connecting section on the lower side. The inclined section is used to guide the core drill 46 to move through the opening 9 when the ground is rugged and the vehicle body 1 cannot be level. The distance between the two vertical sections is the same as the outer diameter of the sampling tube 42. The vertical section is used to limit the sampling tube 42 to prevent the sampling tube 42 from deflecting during sampling. When the vehicle body 1 is moving, the sampling tube 42 can also be controlled to be inserted into the guide frame 11 to maintain stability. The mounting member 10 is used to install the insertion rod 12 and the inclined plate 14. The mounting member 10 The inner diameter of the sampling tube 42 is larger than the outer diameter of the sampling tube 42. The spring 16 is used to elastically support the insertion rod 12 so that the bottom end of the insertion rod 12 is higher than the bottom end of the moving wheel. When the sampling tube 42 descends and passes through the mounting member 10, the bottom end of the inclined plate 14 is pushed to rotate downward. The downward rotation of the inclined plate 14 drives the bottom end of the rod 13 to move downward, and pushes the insertion rod 12 to move downward, so that the bottom end of the insertion rod 12 is lower than the moving wheel and is automatically inserted into the soil, thereby improving the stability of the device during sampling. After the sampling tube 42 rises and leaves the mounting member 10, the elastic force of the spring 16 pushes the insertion rod 12 up and out of the soil.

[0036] Please see attached Figure 8 A spring 803 is arranged inside the piston cylinder 801 , and a notch 804 is opened on one side of the piston cylinder 801 .

[0037] Specifically, spring 2 803 is used to apply elastic force to piston plate 2 802, so that when the external force on piston plate 2 802 disappears, spring 2 803 drives piston plate 2 802 to return to its original position close to notch 804, thereby sucking the gas inside the sampling cylinder 42 back into the piston cylinder 801, so that piston plate 1 6 moves again to the upper area of ​​the sampling cylinder 42 to return to its original position, thereby achieving repeated use. Notch 804 is used for the push rod 809 to be inserted into the interior of the piston cylinder 801.

[0038] Please see attached Figure 8 -Attached Fig. 9 The sample arrangement component 8 also includes a U-shaped sliding member 805, the bottom end of the sliding member 805 is slidably connected to the upper surface of the vehicle body 1, the upper surface of the vehicle body 1 is fixedly connected with a driving motor 806, the driving end of the driving motor 806 is fixedly connected with a lead screw 807, the other end of the lead screw 807 is rotatably connected to the upper surface of the vehicle body 1, the outer wall of the lead screw 807 passes through and is threadedly connected to the lower side wall of the sliding member 805, the interior of the sliding member 805 is fixedly connected with a trapezoidal supporting layer 808, the lower side wall of the sliding member 805 is fixedly connected with an L-shaped pushing rod 809, the top end of the supporting layer 808 is maintained on the same horizontal plane as the bottom end of the sampling tube 42 in a horizontal state, the bottom end of the pushing rod 809 is aligned with the center of the notch 804, and the control module is electrically connected to the driving motor 806 for controlling the driving motor 806.

[0039] Specifically, the driving motor 806 is used to drive the lead screw 807 to rotate, the lead screw 807 is used to drive the sliding member 805 to slide on the vehicle body 1, and the sliding member 805 is used to drive the support layer 808 and the push rod 809 to move. When the sampling tube 42 rotates horizontally, due to the influence of itself and the weight of the sample, it cannot be guaranteed that it will have a certain inclination in the horizontal state. Therefore, the support layer 808 is moved to the bottom of the sampling tube 42 to support it, thereby helping it to maintain the horizontal level and improve the stability during sample arrangement. The inclined surface of the trapezoidal support layer 808 is used to guide the core drill 46 when passing through. The coring drill bit 46 moves to avoid motion interference between the sampling tube 42 in an actual tilted state and the support layer 808. When the push rod 809 moves toward the piston tube 801 and gradually inserts into the interior of the piston tube 801, a thrust is applied to the piston plate 802 to push the piston plate 802 to move to achieve gas delivery, and the sample is gradually squeezed out from the interior of the sampling tube 42 to achieve automatic sample discharge. The speed of sample discharge can be adjusted by controlling the rotation speed of the drive motor 806, and it can be flexibly adjusted according to the needs of the collector to avoid the discharge speed being too fast and affecting the collection operation of the collector.

[0040] Please see attached Figure 8The sample arrangement assembly 8 also includes a semi-circular collecting plate 810 and a supporting plate 811. The top of the collecting plate 810 is rotatably connected to the outer wall of the sliding member 805 through a torsion spring shaft, and the bottom end of the supporting plate 811 is fixedly connected to the upper surface of the vehicle body 1. Extension layers 812 are fixedly connected to both sides of the collecting plate 810. The inner diameter of the collecting plate 810 is the same as the outer diameter of the sampling tube 42. When the collecting plate 810 is kept horizontal, the inner wall fits the outer wall of the horizontal sampling tube 42.

[0041] Specifically, the collecting plate 810 is fitted with the sliding member 805 through the torsion force of the torsion spring shaft, which is used to reduce the shaking amplitude of the collecting plate 810 when the device moves, and at the same time reduce the overall space occupied by the device. When the collecting plate 810 is horizontal, the bottom end of the extension layer 812 and the top end of the support plate 811 are in the same horizontal plane. When the sliding member 805 moves, it drives the collecting plate 810 to move, and the movement of the collecting plate 810 drives the extension layer 812 to move. The extension layer 812 is blocked by the support plate 811, so that the extension layer 812 rotates along the support plate 811 to the horizontal. The horizontal rotation of the extension layer 812 will synchronously drive the collecting plate 810 to rotate horizontally, and then the collecting plate 810 can temporarily store the samples gradually discharged from the sampling tube 42, so that the collectors can collect soil samples of different depths and layers conveniently, and improve the accuracy, convenience and diversity of soil information collection in national land space planning.

[0042] Please see attached Fig.10 A spring telescopic rod 17 is provided on one side of the extension layer 812. The top of the spring telescopic rod 17 is fixedly connected to an L-shaped fixed bracket 18. The bottom end of the fixed bracket 18 is fixedly connected to the upper surface of the vehicle body 1. The spring telescopic rod 17 consists of an upper cylinder, a lower rod body slidably connected to the upper cylinder, and a spring member inside the upper cylinder. The bottom end of the upper cylinder is higher than the top of the extension layer 812 to avoid affecting the rotation of the extension layer 812. The bottom end of the lower rod body is lower than the top of the extension layer 812.

[0043] Specifically, the extension layer 812 in a vertical state can be limited by the spring telescopic rod 17, so that when the device moves on a rough road, the extension layer 812 and the collecting plate 810 are limited to avoid excessive shaking. When the extension layer 812 rotates horizontally, it pushes the spring telescopic rod 17 to contract to avoid motion interference.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
