Description

Technical Field

[0001] This invention relates to the field of geographic information monitoring technology, and in particular to a sample collection device for geographic remote sensing mapping. Background Technology

[0002] A sample collection device for geographic remote sensing mapping is mainly used for ground verification sample collection during the remote sensing mapping process. It can perform standardized and efficient sampling of objects such as soil, vegetation, and surface materials, providing reliable field samples for remote sensing interpretation, data calibration, and geographic monitoring. The device is adaptable to various complex terrain environments such as mountains, deserts, and farmland, ensuring sample integrity and collection accuracy, reducing interference from external factors on sample quality, and improving the matching degree between remote sensing data and field information. It is easy to operate and carry, meeting the needs of long-term continuous field operations. It is widely applicable to scientific research and engineering projects such as resource surveys, ecological monitoring, and land surveying, effectively improving the accuracy and efficiency of geographic remote sensing mapping.

[0003] In practical use, existing devices suffer from uncontrollable sampling depth and mixing of samples from different depths, resulting in samples that cannot accurately reflect the geographical features of each soil layer and depth, thus affecting the matching degree of remote sensing mapping data. Moreover, samples are easily contaminated by external dust and rainwater, and are prone to sticking and deterioration, leading to distorted test results and difficulties in sample preservation. Therefore, a sample collection device for geographic remote sensing mapping is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as uncontrollable sampling depth, mixing of samples from different depths leading to inaccurate reflection of geographical features of each soil layer and depth, thus affecting the matching degree of remote sensing mapping data, and the susceptibility of samples to external dust and rainwater contamination, as well as the tendency of samples to stick together and deteriorate, resulting in distorted detection results and difficulty in sample preservation. Therefore, this invention proposes a sample collection device for geographic remote sensing mapping.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sample collection device for geographic remote sensing mapping includes a main body. A lifting mechanism is fixedly connected to the upper part of the main body. A sampling cylinder is fixedly connected to the upper part of the lifting mechanism. A sealing shell is fixedly connected to the bottom of the sampling cylinder. The sampling shell is fixedly connected to the upper part of the sampling cylinder. A second motor is disposed on the upper part of the sampling shell. A second threaded rod is disposed at the output end of the second motor. A connecting block is threadedly connected to the second threaded rod. A connecting rod is fixedly connected to the lower part of the connecting block. The connecting rod is slidably connected to the sampling cylinder. A sealing drill bit is fixedly connected to the bottom of the connecting rod. A sealing shell is provided inside the sealing shell. The device has a sealing mechanism. During use, the sealing drill bit is placed at the bottom of the sealing housing and forms an integral part therewith. At this time, the lifting mechanism is activated to control the sampling cylinder and the sealing housing to move downwards and drill into the ground. After drilling to the specified depth, the second motor is activated, which drives the sealing drill bit to move upwards and enter the sampling cylinder. Then, the lifting mechanism controls the sampling cylinder to continue to move downwards, thereby achieving sampling at the specified depth. After sampling is completed, the sealing mechanism closes the bottom of the sealing housing to prevent the external environment from affecting the sample. The bottom of the sealing housing is provided with a conical connecting seat, which can form a conical structure with the sealing drill bit, thereby effectively drilling through the ground.

[0006] The above technical solution further includes: The sampling housing is fixedly connected to a first slide rail, and a connecting block is slidably connected to the upper part of the first slide rail.

[0007] The sealing mechanism includes a third motor disposed on one side of the sealing housing. The output end of the third motor is provided with a first gear, which meshes with a second gear. The second gear is rotatably connected to the sealing housing.

[0008] The upper part of the second gear is fixedly connected to the second slide rail, and the upper part of the second slide rail is slidably connected to the slider. The side of the slider away from the second slide rail is fixedly connected to the sliding baffle. The sliding baffle is slidably connected to the sealing shell. There are several sliding baffles, sliders and second slide rails. The sliding baffle has a better sealing effect after being closed, and can effectively isolate the sample from contact with the external environment.

[0009] The lifting mechanism includes a lifting housing fixedly connected to the upper part of the main body of the device, a first motor is provided on one side of the lifting housing, and a lifting component is provided at the output end of the first motor.

[0010] The lifting assembly includes a first transmission wheel located at the output end of a first motor, the first transmission wheel being driven by a transmission belt, the transmission belt being driven by a second transmission wheel, and the second transmission wheel being rotatably connected to the lifting housing.

[0011] The upper part of the second transmission wheel is fixedly connected to a first threaded rod, the first threaded rod is threadedly connected to a movable plate, and a sampling cylinder is fixedly connected to one side of the movable plate.

[0012] The movable plate is fixedly connected to a limiting block on the side away from the sampling cylinder, the limiting block is slidably connected to a limiting rod, and the limiting rod is fixedly connected to the lifting housing.

[0013] The present invention has the following beneficial effects: 1. In this invention, during the use of the device, the sealing drill bit is set at the bottom of the sealing shell and forms an integral part with the conical connecting seat, thereby effectively breaking the ground under the drive of the lifting mechanism. When the sampling tube and the sealing shell are drilled to the preset depth, the second motor is started to drive the sealing drill bit to move upward, thereby being retracted into the sampling tube. Then, the lifting mechanism is controlled to drive the sampling tube to move downward, thereby allowing sampling at a specified depth, effectively avoiding the mixing of soil samples from different layers. Moreover, after the sampling is completed, the sliding baffle can be moved by starting the third motor, thereby sealing the bottom of the sealing shell and effectively isolating the soil sample from the influence of the external environment.

[0014] 2. In this invention, during the use of the device, the first motor can be started to drive the moving plate to move up and down, and the movement of the moving plate can drive the sampling cylinder and the sealing shell to move, thereby controlling the drilling depth of the sampling cylinder and the sealing shell. At the same time, the sampling cylinder and the sealing shell can be recycled after sampling is completed. Moreover, the limiting rod set at the rear end of the moving plate can also ensure that the sampling cylinder and the sealing shell are recycled. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 like Figures 1-6 As shown, a sample collection device for geographic remote sensing mapping includes a main body 1. A lifting mechanism is fixedly connected to the upper part of the main body 1. A sampling cylinder 6 is fixedly connected to the upper part of the lifting mechanism. A sealing shell 7 is fixedly connected to the bottom of the sampling cylinder 6. A sampling shell 4 is fixedly connected to the upper part of the sampling cylinder 6. A second motor 5 is provided on the upper part of the sampling shell 4. A second threaded rod 17 is provided at the output end of the second motor 5. A connecting block 16 is threadedly connected to the second threaded rod 17. A connecting rod 15 is fixedly connected to the lower part of the connecting block 16. The connecting rod 15 is slidably connected to the sampling cylinder 6. A sealing drill bit 8 is fixedly connected to the bottom of the connecting rod 15. A sealing shell 7 is provided inside the sealing shell 7. The sealing mechanism is used in the device. During use, the sealing drill bit 8 is set at the bottom of the sealing housing 7 and forms an integral part with it. At this time, the lifting mechanism is activated to control the sampling cylinder 6 and the sealing housing 7 to move down and drill into the ground. After drilling to the specified depth, the second motor 5 is activated. The second motor 5 drives the sealing drill bit 8 to move up and into the sampling cylinder 6. Then, the lifting mechanism controls the sampling cylinder 6 to continue to move down, thereby achieving sampling at the specified depth. After sampling is completed, the sealing mechanism closes the bottom of the sealing housing 7 to prevent the external environment from affecting the sample. The bottom of the sealing housing 7 is provided with a conical connecting seat. The connecting seat can form a conical structure with the sealing drill bit 8, thereby effectively drilling through the ground.

[0019] The sampling housing 4 is internally fixedly connected to a first slide rail 18, and a connecting block 16 is slidably connected to the upper part of the first slide rail 18. The sealing mechanism includes a third motor 19 disposed on one side of the sealing housing 7. A first gear 20 is disposed at the output end of the third motor 19. The first gear 20 is meshed with a second gear 21. The second gear 21 is rotatably connected to the sealing housing 7. A second slide rail 24 is fixedly connected to the upper part of the second gear 21. A slider 23 is slidably connected to the upper part of the second slide rail 24. A sliding baffle 22 is fixedly connected to the side of the slider 23 away from the second slide rail 24. The sliding baffle 22 is slidably connected to the sealing housing 7. There are several sliding baffles 22, sliders 23 and second slide rails 24. After the sliding baffle 22 is closed, the sealing effect is better and it can effectively isolate the sample from contact with the external environment.

[0020] In this embodiment, during the use of the device, the sealing drill bit 8 is set at the bottom of the sealing housing 7 and forms an integral part with the conical connecting seat, thereby effectively breaking the ground under the drive of the lifting mechanism. When the sampling cylinder 6 and the sealing housing 7 drill into the preset depth, the second motor 5 is started to drive the second threaded rod 17 to rotate. The rotation of the second threaded rod 17 can drive the threaded connecting block 16 to move. During the movement of the connecting block 16, the sliding first slide rail 18 can ensure the stability of the connecting block 16 during movement. The movement of the connecting block 16 can drive the fixed connecting rod 15 to move, thereby driving the sealing drill bit 8, which is fixedly connected to the connecting rod 15, to move upward, so that it is retracted into the sampling cylinder 6. Then, the lifting mechanism is controlled to drive the sampling cylinder 6 to move downward, so that sampling can be performed at the specified depth, effectively avoiding the mixing of soil samples from different layers.

[0021] After sampling is completed, starting the third motor 19 can also drive the first gear 20 to rotate. The rotation of the first gear 20 drives the meshing second gear 21 to rotate, and the rotation of the second gear 21 can drive the slider 23 to move along the second slide rail 24, which in turn drives the sliding baffle 22 to move, thereby sealing the bottom of the sealing shell 7 and effectively isolating the soil sample from the influence of the external environment. Moreover, the sampled soil can be removed from the sampling tube 6 by controlling the downward movement of the sealing drill bit 8. This effectively improves the performance of the device.

[0022] Example 2 like Figures 1-6 As shown, the lifting mechanism includes a lifting housing 2 fixedly connected to the upper part of the main body 1. A first motor 3 is provided on one side of the lifting housing 2. A lifting assembly is provided at the output end of the first motor 3. The lifting assembly includes a first transmission wheel 9 provided at the output end of the first motor 3. The first transmission wheel 9 is driven by a transmission belt 10. The transmission belt 10 is driven by a second transmission wheel 11. The second transmission wheel 11 is rotatably connected to the lifting housing 2. A first threaded rod 12 is fixedly connected to the upper part of the second transmission wheel 11. A moving plate 13 is threadedly connected to the first threaded rod 12. A sampling cylinder 6 is fixedly connected to one side of the moving plate 13. A limit block 25 is fixedly connected to the side of the moving plate 13 away from the sampling cylinder 6. The limit block 25 is slidably connected to a limit rod 14. The limit rod 14 is fixedly connected to the lifting housing 2.

[0023] In this embodiment, during the use of the device, starting the first motor 3 can drive the first transmission wheel 9 to rotate. The rotation of the first transmission wheel 9 drives the transmission belt 10 connected to the transmission to rotate. The rotation of the transmission belt 10 drives the second transmission wheel 11 connected to the transmission to rotate. The rotation of the second transmission wheel 11 drives the first threaded rod 12 fixedly connected to rotate. The rotation of the first threaded rod 12 drives the threaded moving plate 13 to move up and down. The movement of the moving plate 13 can drive the sampling cylinder 6 and the sealing shell 7 to move, thereby controlling the drilling depth of the sampling cylinder 6 and the sealing shell 7. At the same time, the sampling cylinder 6 and the sealing shell 7 can be retrieved after sampling. Moreover, during the movement of the moving plate 13, the limiting block 25 fixedly connected at the rear end slides synchronously along the limiting rod 14, effectively ensuring the stability of the sampling cylinder 6 and the sealing shell 7 during movement.
