Description

Technical Field

[0001] The present invention relates to the technical field of geographic information collection, and in particular to a geographic information collection device based on national land space planning. Background Art

[0002] When planning national land space, geographic information collection devices are needed to collect geographic information. Generally, the soil in a designated area is collected, and then the collected soil is analyzed to obtain the geographic information of the designated area.

[0003] The Chinese invention patent with announcement number CN116879530B discloses a surveying and mapping geographic information data collection tool and its use method. The above-mentioned existing technology inserts a deep-drilling cylinder into the soil, and moves the threaded sleeve to positions of different depths through the operation of the conveyor belt, so that data information of soil at different depths can be collected through the threaded sleeve. In addition, during the collection process, the soil is broken up by breaking up the needle to prevent the detection probe from being damaged by the soil being too hard.

[0004] However, when the soil is relatively loose, the collected soil may become loose when placed in a container such as a collection box, resulting in the loss of the soil sample. This may cause the weight of the soil sample to not reach the required amount, and because the soil is relatively loose, it is inconvenient for the staff to take the soil sample out of the collection device.

[0027] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0028] After the bottom plate is moved to the designated position, it is placed on the ground. The driving mechanism then drives the lifting plate down, which in turn drives the lifting part at the bottom end of rod two to descend. When the slide bar on the rotating plate descends to the bottom along the guide groove, it starts to drive the collection tube and the compression tube into the ground to start sampling. The soil enters the inner cavity of the compression tube. At this time, the distance between the lifting plate and the bottom plate is reduced, which drives the piston shaft to rise in the inner cavity of the piston tube, and transports the water in the inner cavity of the piston tube from tube two to the spray pipe. Then, the water is sprayed into the soil in the inner cavity of the compression tube through the nozzle, which increases the water content of the soil, thereby enhancing the stability of the soil after subsequent compression.

[0029] When the distance between the bottom plate and the lifting plate is reduced, the conical plate enters the inner cavity of the ground insertion tube, and the movable part is pushed toward the triangular plate through the conical plate, so that the triangular plate extends out of the inner cavity of the ground insertion tube, and then the ground insertion tube is inserted into the ground. The triangular plate is triangular, so that the ground insertion tube does not encounter much resistance when it is inserted downward into the ground. When the ground insertion tube is inserted into the ground, the stability of the collection tube and the compression tube in inserting into the ground is improved, and the collection tube and the compression tube are prevented from offsetting when inserted into the ground.

[0030] After the sampling is completed, the driving device is started to drive the threaded rod to rotate, so that the lifting plate rises along the threaded rod and rod one, the lifting plate drives rod two to rise, and rod two drives the lifting part to rise, thereby causing the sliding rod on the rotating plate to rise along the guide groove, and then causing the rotating plate to rotate at the center of the lifting part, so that the lifting part and the rotating plate form a sealed circular plate, and then rise along the guide groove to compress the soil in the inner cavity of the compression cylinder into blocks. At this time, due to the resistance of the triangular plate, the collection cylinder and the compression cylinder will not be pulled out. After full compression, the conical plate rises and the triangular plate shrinks to the inner cavity of the ground-inserted cylinder. Then the collection cylinder and the compression cylinder are pulled out of the ground, and then the switch shell is opened to take out the tightly blocked soil, thereby avoiding the loosening of the soil, which leads to inconvenience in sampling.

DETAILED DESCRIPTION

[0044] Example 1, as Figures 1-12 As shown, the present invention proposes a geographic information collection device based on national land space planning, which includes a base plate 1, a water replenishment mechanism, a compression mechanism, and a driving mechanism.

[0045] The driving mechanism is mounted on the base plate 1, and a lifting plate 4 is mounted on the driving end;

[0046] The water replenishing mechanism is installed on the lifting plate 4 and is used to replenish water into the collected soil;

[0047] The compression mechanism is mounted on the lifting plate 4;

[0048] The compression mechanism includes a compression component, a sampling component, a ground insertion component, a driving component, a locking component, a guide groove 12 and a triangular plate 18; the compression component is installed at the bottom of the lifting plate 4 and the bottom end extends to the bottom end of the sampling component; the sampling component is located below the lifting plate 4; the guide groove 12 is opened on the sampling component, and the compression component is slidably connected to the guide groove 12; the ground insertion component is installed on the sampling component and is used to insert the sampling component into the ground so that the sampling component is not easily pulled out; the triangular plate 18 is installed in the ground insertion component; the driving component is installed at the bottom end of the lifting plate 4 and is used to be inserted into the ground insertion component to drive the triangular plate 18 to move; the locking component is installed on the ground insertion component to lock the driving component; the sampling component is inserted into the ground to collect soil, and the ground insertion component is also inserted into the ground at the same time. Then the driving mechanism drives the lifting plate 4 to rise and drives the compression component to compress the soil in the sampling component and then bring the sampling component out of the ground.

[0049] The guide groove 12 consists of an inclined section and a vertical section. The vertical section is located above the inclined section. When the slide bar 9 on the rotating plate 8 moves along the inclined section, it will drive the rotating plate 8 to rotate in the inner cavity of the lifting part 7. After the lifting part 7 and the rotating plate 8 form a sealed circular plate, it will rise along the vertical section and squeeze the soil in the inner cavity of the compression cylinder 13 into blocks.

[0050] There are two guide grooves 12 , which are respectively opened on both sides of the inner wall of the collection tube 11 .

[0051] The compression assembly includes a rod 2 6, a lifting part 7, a rotating plate 8, a sliding rod 9 and a tapered block 10;

[0052] Rod 2 6 is installed at the bottom end of the lifting plate 4, and the lifting part 7 is installed at the bottom end of rod 2 6. The rotating plate 8 is movably connected in the lifting part 7. The sliding rod 9 is installed on the rotating plate 8, and the rotating plate 8 is slidably connected in the guide groove 12; the lifting part 7 drives the rotating plate 8 to rise, and the rotating plate 8 rotates along the guide groove 12 and out of the inner cavity of the lifting part 7 with the central axis of the lifting part 7, so that the lifting part 7 and the rotating plate 8 form a sealed circular plate.

[0053] The conical block 10 is a conical body. When the rod 2 6 drives the lifting part 7 to descend, and the lifting part 7 drives the collecting tube 11 to descend, the soil will enter the inner cavity of the collecting tube 11 and the compression tube 13 along the cone shape of the conical block 10.

[0054] The sampling assembly includes a collection tube 11, a compression tube 13, a switch housing 14, a bolt 25 and a threaded groove 26;

[0055] The compression cylinder 13 is located at the bottom end of the lifting plate 4, the collection cylinder 11 is installed at the bottom end of the compression cylinder 13, the guide groove 12 is opened on the inner wall of the collection cylinder 11, the compression cylinder 13 is rotatably connected to the switch housing 14, the switch housing 14 is rotatably connected to the bolt 25, the compression cylinder 13 is provided with a threaded groove 26, and the bolt 25 is threadedly connected to the threaded groove 26; the compression assembly compresses the soil in the inner cavity of the compression cylinder 13. When the compression cylinder 13 is pulled out of the ground, the switch housing 14 is opened to take out the compressed soil.

[0056] When sampling, the bolt 25 on the switch housing 14 is screwed into the threaded groove 26 to lock the switch housing 14. After sampling, the bolt 25 is unscrewed to open the switch housing 14. Then the staff takes out the soil from the inner cavity of the compression cylinder 13.

[0057] The second rod 6 is installed on the side of the top of the lifting part 7 away from the switch housing 14. Through the arrangement of the second rod 6, after the soil in the inner cavity of the compression cylinder 13 is squeezed into blocks, the second rod 6 will not affect the soil in the blocks.

[0058] The compression cylinder 13 is located above the guide groove 12 , so that the lifting portion 7 and the rotating plate 8 rise to squeeze the soil in the inner cavity of the compression cylinder 13 .

[0059] The ground insertion assembly includes a ground insertion tube 15, an elastic member 16 and a movable part 17;

[0060] one end of an elastic member 16 is installed in the ground-inserted tube 15, and the other end is connected to the movable portion 17, the outer side of the movable portion 17 is connected to the triangular plate 18, and the movable portion 17 is Z-shaped.

[0061] The elastic member 16 is composed of a spring 2 and a telescopic rod.

[0062] The drive assembly includes a conical plate 19 and a circular hole 20;

[0063] The conical plate 19 is installed at the bottom end of the lifting plate 4, and the circular hole 20 is opened on the triangular plate 18; the conical plate 19 is inserted into the ground insertion tube 15, squeezing the movable part 17 to move, so that the triangular plate 18 extends out of the ground insertion tube 15.

[0064] When the conical plate 19 is inserted into the ground insertion tube 15, the triangular plate 18 provides resistance, so that when the lifting part 7 and the rotating plate 8 press the soil upward, the collecting tube 11 and the compression tube 13 will not be pulled upward. When the lifting plate 4 drives the lifting part 7 and the rotating plate 8 at the bottom end of the rod 2 6 to rise a certain distance, the conical plate 19 rises and separates from the two movable parts 17. At this time, the elastic force of the spring 1 21 drives the rod 3 22 to be inserted into the circular hole 20 to lock the conical plate 19, ensuring that the soil compressed in the inner cavity of the compression tube 13 will not push the lifting part 7 and the rotating plate 8 open.

[0065] The locking assembly includes a spring 1 21, a rod 3 22, a pull ring 23 and a rotating wheel 24;

[0066] One end of spring 1 21 is installed in the ground insertion tube 15, and the other end thereof is installed with rod 3 22. Rod 3 22 passes through the ground insertion tube 15 and connects to the pull ring 23. A rotating wheel 24 is installed on rod 3 22. After the lifting plate 4 drives the conical plate 19 to rise, rod 3 22 drives the rotating wheel 24 to insert into the circular hole 20 to lock the conical plate 19.

[0067] The driving mechanism includes a driving device 2, a threaded rod 3 and a rod 5;

[0068] The driving device 2 is a servo motor.

[0069] The driving device 2 is installed on the top of the base plate 1, and its transmission connection threaded rod 3 is threadedly matched with the lifting plate 4. A rod 5 is installed on the base plate 1, and the lifting plate 4 and the rod 5 are movably connected.

[0070] Example 2, as Figure 1-Figure 3 、 Figure 11 and Figure 12 As shown, the present invention proposes a device for collecting geographic information based on land space planning. Compared with the first embodiment, the water replenishment mechanism of this embodiment includes a spray assembly, a water tank 27, a pipe 28, a one-way valve 29, a piston cylinder 30 and a piston shaft 31;

[0071] The water tank 27 and the piston cylinder 30 are both mounted on the lifting plate 4, and the two ends of the pipe 1 28 are respectively connected to the bottom end of the water tank 27 and the top end of the piston cylinder 30; the one-way valve 29 is mounted on the pipe 1 28; the piston shaft 31 is mounted on the base plate 1 and its large end is movably sleeved in the piston cylinder 30; the spray assembly is connected to the piston cylinder 30, and the spray section is mounted in the rod 2 6.

[0072] The water in the inner cavity of the water tank 27 can enter the piston cylinder 30 through the tube 1 28 and the one-way valve 29, while the water in the inner cavity of the piston cylinder 30 cannot enter the water tank 27 through the tube 1 28 and the one-way valve 29.

[0073] A plug is plugged into the top of the water tank 27 . When the water in the inner cavity of the water tank 27 is used up, the plug is pulled out and water is then added to the inner cavity of the water tank 27 .

[0074] When the collection cylinder 11 and the compression cylinder 13 are pulled out from the ground, the piston shaft 31 descends in the inner cavity of the piston cylinder 30, thereby drawing the water in the inner cavity of the water tank 27 into the inner cavity of the piston cylinder 30 through the pipe 1 28 and the one-way valve 29.

[0075] The spray assembly includes pipe 2 32, spray pipe 33 and nozzle 34;

[0076] The second tube 32 is connected to the top of the piston cylinder 30, and the bottom end of the second tube 32 extends to the second rod 6 to install a spray pipe 33, and a nozzle 34 is installed on the spray pipe 33; water is sprayed into the collected soil through the nozzle 34.

[0077] The nozzle 34 is inclined upward from the compression cylinder 13 to prevent the nozzle 34 from being blocked by soil.

[0078] In summary, in the present invention, the drawings in the specification show the state of the application after being inserted into the ground.

[0079] The piston cylinder 30 is filled with water, and then the pull ring 23 is pulled to make the rod three 22 leave the inner cavity of the circular hole 20. After the base plate 1 is placed in the specified position, the driving device 2 is started to drive the threaded rod 3 to rotate, thereby driving the lifting plate 4 engaged with it to descend along the axial direction of the threaded rod 3 and rod one 5, and then driving rod two 6 to descend. When rod two 6 descends, it drives the lifting part 7 and the rotating plate 8 to descend. When the sliding rod 9 on the rotating plate 8 moves to the bottom end along the guide groove 12, it drives the collecting cylinder 11 and the compression cylinder 13 to descend, and the collecting cylinder 11 and the compression cylinder 13 are inserted into the ground. Then the soil enters the inner cavity of the collecting cylinder 11 and the compression cylinder 13 through the conical block 10.

[0080] At the same time, the piston shaft 31 moves upward in the inner cavity of the piston cylinder 30, thereby squeezing the water in the inner cavity of the piston cylinder 30 into the spray pipe 33 through the second pipe 32, and then spraying it into the inner cavity of the compression cylinder 13 through the nozzle 34 on the spray pipe 33, thereby moistening the soil in the inner cavity of the compression cylinder 13.

[0081] At the same time, the conical plate 19 squeezes the movable part 17 of the inner cavity of the ground insertion tube 15 to move toward the direction of the triangular plate 18, and the triangular plate 18 extends out of the inner cavity of the ground insertion tube 15, and then the ground insertion tube 15 is inserted into the ground. Due to the shape of the triangular plate 18, when the ground insertion tube 15 is inserted downward into the ground, it will not affect the descent of the compression tube 13 and the ground insertion tube 15.

[0082] When the sampling is completed, the driving device 2 drives the threaded rod 3 to be reversed, so that the lifting plate 4 rises, and then drives the rod 2 6 to rise. At this time, the sliding rod 9 on the rotating plate 8 moves along the guide groove 12, driving the rotating plate 8 to rotate out of the inner cavity of the lifting part 7 with the center of the lifting part 7 as the axis, so that the lifting part 7 and the rotating plate 8 form a sealed circular plate, and because the triangular plate 18 and the ground-inserting tube 15 are inserted into the ground, the collecting tube 11 and the compression tube 13 are not easy to be pulled out. Then the lifting part 7 and the rotating plate 8 rise along the guide groove 12 to compress the soil in the inner cavity of the compression tube 13 tightly, and because the soil is moist, it has better stability after compression molding.

[0083] At the same time, the lifting plate 4 drives the conical plate 19 to rise. When the conical plate 19 is separated from the movable part 17, the elasticity of the spring 1 21 drives the rod 3 22 to be inserted into the circular hole 20, thereby limiting and locking the conical plate 19. At the same time, the elasticity of the elastic member 1 16 drives the triangular plate 18 back to the inner cavity of the ground insertion tube 15, releasing the lock of the triangular plate 18 on the ground insertion tube 15, so that the compression tube 13 can be pulled out of the ground.

[0084] Then the lifting part 7 and the rotating plate 8 pull the collecting cylinder 11 and the compression cylinder 13 out of the soil, then unscrew the bolt 25 from the thread groove 26, open the switch housing 14, and then take out the soil block in the inner cavity of the compression cylinder 13.

[0085] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
