Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and more particularly to a soil detection device based on satellite remote sensing. Background Art

[0002] Soil monitoring refers to determining the environmental quality (or pollution level) and its changing trend by measuring the representative values ​​of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical contents such as sampling, sample preparation, analysis methods, result representation, data statistics and quality evaluation.

[0003] For example, the existing detection device has patent number 201611197363.4, and its name is a patent for an exercise-type soil sampling device. Its sampling method requires manual rotation of the corresponding mechanism to achieve sampling, and then the sampling device needs to be manually removed for testing. After the test, the soil needs to be manually discharged. The operation process is relatively complicated and inefficient. The device cannot automatically clean the inner surface of the sampling device, which makes it easy to cross-infection when sampling again, thereby affecting the accuracy of the device's detection.

[0048] A rectangular opening 77 is provided on the lower surface of the rectangular box body 1, a fixed tube 78 is installed on one side of the rectangular opening 77, a sliding rod 79 is installed on the inner surface of the fixed tube 78, a U-shaped fork 80 is installed on one end of the sliding rod 79, the U-shaped fork 80 corresponds to the position of the triangular baffle 22, a rectangular block 81 is installed on the other end of the sliding rod 79, and a long through hole 82 is provided on the side surface of the rectangular block 81; a support rod 83 is installed on the side surface of the rectangular box body 1, an L-shaped connecting rod 90 is installed on one end of the support rod 83, the L-shaped connecting rod 90 is hinged to the support rod 83, a pin 84 slidably connected to the long through hole 82 is installed on the lower end of the L-shaped connecting rod 90, a spring sheet 85 is installed on the upper end of the L-shaped connecting rod 90, a limiting block 86 is installed on one end of the spring sheet 85, and a tension spring 87 is installed between the side surface of the L-shaped connecting rod 90 and the support rod 83, and the swinging action of the L-shaped connecting rod 90 can prevent the rotating cylinder 11 from falling automatically.

[0049] A tire 88 is mounted on the outer surface of the spoke motor 73 .

[0050] A remote sensing antenna 89 is installed at one end of the upper surface of the rectangular box 1, and satellite remote sensing can be achieved through the remote sensing antenna 89.

[0051] In this embodiment, a battery is installed inside the rectangular box 1. The battery can provide energy for the electrical appliances of the entire device. A controller is installed on the upper end of the steering rod 71 to facilitate the operation of the control device. The spoke motor 23 belongs to the prior art, similar to the driving motor of an electric car. This motor can drive the movement of the entire device. When soil detection is required, the steering rod 71 is manually pushed while the spoke motor 73 is controlled to rotate. This operation can realize the flexible movement of the device. The support of the roller bracket 72 and the bearing 470 can make the device turn stably. Two moving wheels 68 are provided on the other side of the rectangular box 1. The moving wheels 68 combined with the spoke motor 73 can provide a stable center for the device.

[0052] When the device moves to the designated position, the controller controls the electric telescopic rod 29 to extend, and the extension of the electric telescopic rod 29 directly drives the metal ball 32 at the telescopic end to move downward until the metal ball 32 is stuck in the annular groove 26. Figure 8 As shown, at this time, the U-shaped fork 80 is inserted into the lower end of the rotating cylinder 11, as shown in FIG. Fig.15 As shown, the falling of the rotating cylinder 11 is prevented. Due to the action of the compression spring 1 31, the telescopic end of the electric telescopic rod 29 and the connecting ring 24 are in a connected state. When docking, the electric telescopic rod 29 can be inserted into the bearing 3 25 more easily through the action of the guide plate 74. At this time, the controller controls the stepper motor 1 9 to rotate. The rotation of the stepper motor 1 9 directly drives the gear 2 10 to rotate. The rotation of the gear 2 10 directly drives the gear 1 8 to rotate. Through the connection mode of the fixed block 2 7, the rotating cylinder 11 can be directly driven to rotate. The rotation of the rotating cylinder 11 drives the connecting ring 24 and the limit ring 27 to rotate. When the rectangular notch 28 on one side of the limit ring 27 overlaps with the limit block 86; the L-shaped connecting rod 90 is stretched by the tension spring 87, and the entire L-shaped connecting rod 90 rotates counterclockwise, as shown in FIG. Fig.13 and Fig.14 , the lower end of the L-shaped connecting rod 90 drives the sliding rod 79 and the U-shaped fork 80 to slide to one side, at which time the U-shaped fork 80 is separated from the rotating cylinder 11, and the rotating cylinder 11 can move downward by the extension of the electric telescopic rod 29 again. While moving downward, the stepper motor 9 indirectly drives the triangular baffle 22 and the drill bit 23 to rotate and drill toward the surface; after drilling to a certain depth, the stepper motor 9 rotates in the opposite direction by a certain angle to make the adjusting cylinder 15 and the rotating cylinder 11 produce relative movement. While the relative movement is in progress, one end of the connecting rod 18 will swing at a certain angle along the trajectory of the arc groove 20, so that the fan-shaped rubber plate 21 changes from an open state to a closed state as shown in FIG. Figure 3 to Figure 2 The state of the electric telescopic rod 29 is prevented from falling when it rises. At this time, the electric telescopic rod 29 contracts and drives the connecting ring 24 to rise. In the process of soil sampling, the number of rotations of the stepping motor 9 is a full circle. This method can make the rectangular notch 28 and the limit block 86 in a misaligned state, which is convenient for the connecting ring 24 to interfere with the limit block 86 when it rises. When the connecting ring 24 contacts the spring sheet 85, the L-shaped connecting rod 90 will not move due to the elasticity of the spring sheet 85. When the adjusting cylinder 15 moves to the top of the sliding rod 79, it is affected by the rebound of the spring sheet 85, and the elastic force is greater than the pulling force of the tension spring 87. At this time, the U-shaped fork 80 is inserted into the triangular baffle 22 to drag the rotating cylinder 11 again. At this time, the sampling is completed;

[0053] At this time, the electric telescopic rod 29 is retracted again, so that the metal ball 32 is separated from the connecting ring 24 and retracted to the top. Fig. 9As shown, the controller controls the stepper motor 2 34 to rotate, so that the vertical cylinder 1 38 rotates to the top of the rotating cylinder 11, as shown in FIG. Fig.19 As shown, at this time, the electric telescopic rod 29 extends and supports the circular baffle 40 and slides downward. The sliding of the circular baffle 40 drives the humidity sensor 44 to be inserted into the soil in the rotating cylinder 11 through the center of the sliding ring 33 for detection. The detection item designed this time is soil humidity. According to actual needs, the humidity sensor 44 is replaced with a corresponding sensor. After the detection is completed, the electric telescopic rod 29 shrinks to the top, the circular baffle 40 is expanded by the compression spring 43, and the humidity sensor 44 is reset. At this time, the detection is completed, and the detected data is transmitted to the soil detector 45 through the connecting line 91, and the remote sensing antenna 89 realizes satellite remote sensing;

[0054] After the detection is completed, the soil needs to be discharged. The controller first controls the stepper motor 19 to rotate in the opposite direction. Since the U-shaped fork 80 can clamp the main rotating cylinder 11, the rotating cylinder 11 and the adjusting cylinder 15 can move relative to each other, which indirectly opens the fan-shaped rubber plate 21 to facilitate the discharge of the soil. Then, the stepper motor 234 is controlled to rotate, so that the vertical cylinder 246 rotates to the top of the rotating cylinder 11. Fig. 20 As shown, at this time, the electric telescopic rod 29 is extended and pushes the sliding plate 48 to slide downward. The sliding plate 48 slides downward and drives the hollow sealing rod 52 to move downward. The lower end of the hollow sealing rod 52 pushes the sliding ring 33 to move downward. This structure prevents the hollow sealing rod 52 from directly contacting the soil, thereby ensuring the cleanliness of the lower end of the hollow sealing rod 52. The structure of the lower end of the hollow sealing rod 52 is three protruding points, and there are gaps between the points, such as Fig.12 As shown, the shaded part is the contact part, and the secondary structure facilitates the discharge of water. When the sliding ring 33 moves to the lowest end, the soil discharge is completed; the controller controls the suction pump 57 to work so that the water in the water tank 56 is input into the hollow sealing rod 52 through the suction pump 57 and the water pipe 55, and is sprayed out from the water permeable hole 53 to wash the inner surface of the rotating cylinder 11, and the waste water flows out through the gap at the lower end of the hollow sealing rod 52 and the circular hole in the center of the sliding ring 33, so as to achieve the purpose of cleaning; then the electric telescopic rod 29 is retracted to the top, and the compression spring 3 51 rebounds to reset the hollow sealing rod 52;

[0055] After cleaning is completed, the controller controls the stepper motor 2 34 to rotate at a certain angle, such as Fig.21As shown, the vertical cylinder 3 58 is moved to the top of the rotating cylinder 11. At this time, the controller controls the electric telescopic rod 29 to extend and drive the moving plate 60 and the sealing tube 63 to slide downward. When the sealing tube 63 moves to the lower end of the rotating cylinder 11, the controller controls the hot air blower 66 to work. The hot air blower 66 heats the air and transmits it to the sealing tube 63 through the air pipe 65. The hot air is discharged through the air outlet 64 and blows to the inside of the rotating cylinder 11 to dry the inside of the rotating cylinder 11. At this time, the inside of the rotating cylinder 11 remains clean. After drying for a certain period of time, the electric telescopic rod 29 shrinks to the top, and the controller controls the stepping motor 2 34 to rotate, so that the vertical cylinder 1 38 is reset as shown in FIG. Fig.18 As shown; the operation of the entire process is now completed.
