Description

Technical Field

[0001] The present invention relates to the technical field of geographic information collection, and particularly relates to a geographic information collection device based on territorial spatial planning. Background Art

[0002] During territorial spatial planning, a geographic information collection device is 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 the publication number CN116879530B discloses a surveying and mapping geographic information data collection tool and its usage method. In the above prior art, an insertion tube is inserted into the soil, and the threaded sleeve is moved to different depths through the operation of the conveyor belt, so as to collect data information of soils at different depths through the threaded sleeve. In addition, during the collection process, the soil is dispersed by a dispersing needle to prevent the detection probe from being damaged due to too hard soil.

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

When the compression cylinder is pulled out of the ground, the switch housing is opened to take out the compressed soil.

[0009] Preferably, the ground - inserting component includes a ground - inserting cylinder, an elastic part one and a movable part; The ground - inserting cylinder is installed on the sampling component; one end of the elastic part one is installed inside the ground - inserting cylinder, its other end is connected to the movable part, and the outside of the movable part is connected to the triangular plate.

[0010] Preferably, the driving component includes a conical plate and a round hole; The conical plate is installed at the bottom end of the lifting plate, the round hole is opened on the triangular plate; the conical plate is inserted into the ground - inserting cylinder, squeezing the movable part to move, so that the triangular plate extends out of the ground - inserting cylinder.

[0013] Preferably, the water replenishing mechanism includes a spraying assembly, a water tank, a first pipe, a check valve, a piston cylinder, and a piston shaft; Both the water tank and the piston cylinder are installed on the lifting plate.

[0015] Compared with the prior art, the above technical solutions of the present invention have the following beneficial technical effects: After moving the bottom plate to the designated position and placing it on the ground, then the driving mechanism drives the lifting plate to descend, thereby driving the lifting part at the bottom end of the second rod to descend. When the sliding rod on the rotating plate descends to the bottom along the guide groove, it starts to drive the sampling cylinder and the compression cylinder to be inserted into the ground for sampling. The soil enters the inner cavity of the compression cylinder. At this time, the distance between the lifting plate and the bottom plate is reduced, thereby driving the piston shaft to rise in the inner cavity of the piston cylinder, and conveying the water in the inner cavity of the piston cylinder from the second pipe to the spraying pipe, and then spraying the water into the soil in the inner cavity of the compression cylinder through the nozzle, increasing the water content of the soil, thereby enhancing the stability of the subsequent compressed soil.

[0016] When the distance between the bottom plate and the lifting plate is reduced, the conical plate enters the inner cavity of the ground insertion cylinder, and pushes the movable part towards the triangular plate through the conical plate, thereby causing the triangular plate to extend out of the inner cavity of the ground insertion cylinder. Subsequently, the ground insertion cylinder is inserted into the ground. Since the triangular plate is triangular, the ground insertion cylinder is not subject to too much resistance when being inserted into the ground. When the ground insertion cylinder is inserted into the ground, the stability of the sampling cylinder and the compression cylinder inserted into the ground is improved, and the sampling cylinder and the compression cylinder are prevented from shifting when being inserted into the ground.

[0017] 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. Furthermore, the sliding rod on the rotating plate rises along the guide groove. Furthermore, the rotating plate rotates around the center of the lifting part. After the lifting part and the rotating plate form a sealed circular plate, it rises along the guide groove to compress the soil in the inner cavity of the compression cylinder tightly into a block. At this time, due to the resistance of the triangular plate, the collecting cylinder and the compression cylinder will not be pulled out. When the compression is complete, the conical plate rises and the triangular plate contracts into the inner cavity of the ground insertion cylinder. Subsequently, the collecting cylinder and the compression cylinder are pulled out of the ground. Then the switch housing is opened, and the tightly formed soil is taken out, thus avoiding the looseness of the soil and the inconvenience during sampling. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0020] Embodiment 1, as Figures 1-12 shown, a geographic information collection device based on territorial space planning proposed by the present invention includes a bottom plate 1, a water replenishing mechanism, a compression mechanism, and a driving mechanism.

[0021] The driving mechanism is installed on the bottom plate 1, and a lifting plate 4 is installed on the driving end; The water replenishing mechanism is installed on the lifting plate 4 and is used to replenish water into the collected soil; The compression mechanism is installed on the lifting plate 4; The compression mechanism includes a compression assembly, a sampling assembly, a ground insertion assembly, a driving assembly, a locking assembly, a guide groove 12, and a triangular plate 18; the compression assembly is installed at the bottom of the lifting plate 4 and the bottom end extends to the bottom end of the sampling assembly; the sampling assembly is located below the lifting plate 4; the guide groove 12 is opened on the sampling assembly, and the compression assembly is slidably connected with the guide groove 12; the ground insertion assembly is installed on the sampling assembly and is used to make the sampling assembly not easy to be pulled out after being inserted into the ground; the triangular plate 18 is installed inside the ground insertion assembly; the driving assembly is installed at the bottom end of the lifting plate 4 and is used to drive the triangular plate 18 to move inside the inserted ground insertion assembly; the locking assembly is installed on the ground insertion assembly and is used to lock the driving assembly; the sampling assembly is inserted into the ground to collect soil, and at the same time the ground insertion assembly is also inserted into the ground. Subsequently, the driving mechanism drives the lifting plate 4 to rise, driving the compression assembly, compacting the soil in the sampling assembly tightly, and then taking the sampling assembly out of the ground.

[0022] The guide groove 12 is composed of an inclined section and a vertical section. The vertical section is located above the inclined section. When the sliding rod 9 on the rotating plate 8 walks along the inclined section, it will drive the rotating plate 8 to rotate inside the cavity of the lifting part 7. When the lifting part 7 and the rotating plate 8 form a sealed circular plate, it then rises along the vertical section to squeeze the soil in the cavity of the compression cylinder 13 tightly into a block.

[0023] There are two guide grooves 12 in total, and the two guide grooves 12 are respectively opened on both sides of the inner wall of the collection cylinder 11.

[0024] The compression assembly includes a rod two 6, a lifting part 7, a rotating plate 8, a sliding rod 9, and a tapered block 10; The second rod 6 is installed at the bottom end of the lifting plate 4. The bottom end of the second rod 6 is installed with a lifting part 7. The rotating plate 8 is movably sleeved in the lifting part 7. A sliding rod 9 is installed on the rotating plate 8. The rotating plate 8 is slidably connected in the guide groove 12. The lifting part 7 drives the rotating plate 8 to rise. The rotating plate 8 rotates out of the inner cavity of the lifting part 7 along the guide groove 12 and 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.

[0025] The conical block 10 is a conical body. When the second rod 6 drives the lifting part 7 to descend and the lifting part 7 drives the collecting cylinder 11 to descend, the soil will enter the inner cavities of the collecting cylinder 11 and the compression cylinder 13 along the cone of the conical block 10.

[0026] The sampling assembly includes a collecting cylinder 11, a compression cylinder 13, a switch housing 14, a bolt 25 and a threaded groove 26; The compression cylinder 13 is located at the bottom end of the lifting plate 4. The collecting 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 collecting cylinder 11. The switch housing 14 is rotatably connected to the compression cylinder 13. The bolt 25 is rotatably connected to the switch housing 14. The threaded groove 26 is opened on the compression cylinder 13. 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.

[0027] During 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 screwed out, so that the switch housing 14 is opened, and then the staff takes out the soil in the inner cavity of the compression cylinder 13.

[0028] The second rod 6 is installed on the side of the top end of the lifting part 7 away from the switch housing 14. Through the setting 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 formed soil blocks.

[0029] The compression cylinder 13 is located above the guide groove 12, so that the lifting part 7 and the rotating plate 8 rise to squeeze the soil in the inner cavity of the compression cylinder 13.

[0030] The ground insertion assembly includes a ground insertion cylinder 15, a first elastic member 16 and a movable part 17; The ground insertion cylinder 15 is installed on the sampling assembly. One end of the first elastic member 16 is installed in the ground insertion cylinder 15, and the other end thereof is connected to the movable part 17. The outer side of the movable part 17 is connected to a triangular plate 18. The movable part 17 is Z-shaped.

[0031] The first elastic member 16 is composed of a second spring and a telescopic rod.

[0032] The driving assembly includes a conical plate 19 and a circular hole 20; 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 inserting tube 15 , and the movable part 17 is pressed to move, so that the triangular plate 18 extends out of the ground inserting tube 15 .

[0033] When the conical plate 19 is inserted into the ground-inserting 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 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.

[0034] The locking assembly includes a spring 1 21, a rod 3 22, a pull ring 23 and a rotating wheel 24; 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, and 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.

[0035] The driving mechanism includes a driving device 2, a threaded rod 3 and a rod 5; The driving device 2 is a servo motor.

[0036] The driving device 2 is installed on the top of the base plate 1, and its transmission is connected to the threaded rod 3. The 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.

[0037] Embodiment 2, as Figures 1-3 , Figure 11 and Figure 12 As shown, the present invention proposes a geographic information collection device 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; The water tank 27 and the piston cylinder 30 are both installed on the lifting plate 4, and the two ends of the pipe 1 28 are respectively connected with the bottom end of the water tank 27 and the top end of the piston cylinder 30; the one-way valve 29 is installed on the pipe 1 28; the piston shaft 31 is installed on the bottom 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 installed in the rod 2 6.

[0038] 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.

[0039] A plug is inserted at the top of the water tank 27. After the water in the inner cavity of the water tank 27 is used up, the plug is pulled out, and then water is replenished into the inner cavity of the water tank 27.

[0040] When the collecting 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, so as to pump the water in the inner cavity of the water tank 27 into the inner cavity of the piston cylinder 30 through the pipe one 28 and the one-way valve 29.

[0041] The spraying assembly includes a pipe two 32, a spraying pipe 33 and a nozzle 34; The pipe two 32 communicates with the top end of the piston cylinder 30. The bottom end of the pipe two 32 extends into the rod two 6 to install the spraying pipe 33, and the nozzle 34 is installed on the spraying pipe 33; Water is sprayed onto the collected soil through the nozzle 34.

[0042] The nozzle 34 inclines upward from the compression cylinder 13, so as to prevent the soil from blocking the nozzle 34.

[0043] In summary, in the present invention, the state after the present application is inserted into the ground is shown in the accompanying drawings of the specification.

[0044] Water is filled in the piston cylinder 30. Then, the pull ring 23 is pulled to make the rod three 22 leave the inner cavity of the round hole 20. After the bottom plate 1 is placed at the designated position, the driving device 2 is started to drive the threaded rod 3 to rotate, so as to drive the lifting plate 4 engaged therewith to descend along the axial directions of the threaded rod 3 and the rod one 5, and then drive the rod two 6 to descend. When the 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 inserts the collecting cylinder 11 and the compression cylinder 13 into the ground. Subsequently, the soil enters the inner cavities of the collecting cylinder 11 and the compression cylinder 13 through the tapered block 10.

[0045] At the same time, the piston shaft 31 moves upward in the inner cavity of the piston cylinder 30, so as to squeeze the water in the inner cavity of the piston cylinder 30 into the spraying pipe 33 through the pipe two 32, and then spray it out through the nozzle 34 on the spraying pipe 33 into the inner cavity of the compression cylinder 13 to moisten the soil in the inner cavity of the compression cylinder 13.

[0046] At the same time, the tapered plate 19 squeezes the movable part 17 in the inner cavity of the ground inserting cylinder 15 to move towards the triangular plate 18. The triangular plate 18 extends out of the inner cavity of the ground inserting cylinder 15. Subsequently, the ground inserting cylinder 15 is inserted into the ground. Due to the shape of the triangular plate 18, when the ground inserting cylinder 15 is inserted downward into the ground, it will not affect the descent of the compression cylinder 13 and the ground inserting cylinder 15.

[0047] After the sampling is completed, the driving device 2 drives the threaded rod 3 to reverse, causing the lifting plate 4 to rise, and then driving the second rod 6 to rise. At this time, the slide 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. Since the triangular plate 18 and the ground-inserting cylinder 15 are inserted into the ground, it is not easy to pull out the sampling cylinder 11 and the compression cylinder 13. Subsequently, 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 cylinder 13 tightly. And because the soil is wet, after compression molding, the stability is better.

[0048] At the same time, the lifting plate 4 drives the conical plate 19 to rise. After the conical plate 19 is separated from the movable part 17, the elastic force of the first spring 21 drives the third rod 22 to insert into the circular hole 20 to limit and lock the conical plate 19. At the same time, the elastic force of the first elastic member 16 drives the triangular plate 18 back into the inner cavity of the ground-inserting cylinder 15, releasing the locking of the triangular plate 18 on the ground-inserting cylinder 15, so that the compression cylinder 13 can be pulled out of the ground.

[0049] Subsequently, the lifting part 7 and the rotating plate 8 pull out the sampling cylinder 11 and the compression cylinder 13 from the land. Then, the bolt 25 is screwed out of the thread groove 26, the switch housing 14 is opened, and then the soil block in the inner cavity of the compression cylinder 13 is taken out.

[0050] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
