Description

Technical Field

[0001] The utility model relates to the technical field of soil collection, in particular to a soil sampling unmanned aerial vehicle for hilly and mountainous areas. Background Art

[0002] Collecting soil and detecting its physical and chemical properties can provide a scientific basis for soil improvement, soil erosion control, environmental monitoring, etc. Traditional soil sampling methods mainly rely on manual soil drilling, which consumes a lot of resources and has a very low sampling efficiency. Moreover, it is inevitable to cause damage to the local natural ecology during the process of reaching the sampling point. In addition, some sampling points are distributed in deep mountains, steep cliffs, and remote areas, which are inaccessible by manpower alone and it is difficult to complete the soil collection work. If these sampling points are abandoned, the results will be deviated.

[0003] As disclosed in the utility model with the authorization announcement number CN221199036U, an automatic soil collection device based on an unmanned aerial vehicle has a simple structure, scientific and reasonable design. The soil sampling device can extend into the soil and take out a sample with a certain thickness, and can sample the soil on slopes.

[0004] The following problems still exist when this prior art is in use:

[0005] The device is provided with a liftable unmanned aerial vehicle bracket to support the unmanned aerial vehicle body. However, in actual use, when sampling on the ground with complex environments such as hilly and mountainous areas, the ground may be uneven. When the unmanned aerial vehicle bracket lands on such a ground, it may cause the unmanned aerial vehicle body to tilt, thereby reducing the stability of the unmanned aerial vehicle body. Moreover, there are wild grasses growing on the ground of the hills. When the gripper claws of the device are in use, they may grasp on the leaf stems of the wild grasses and cannot directly contact the ground, thus unable to effectively support the unmanned aerial vehicle body. And during subsequent sampling, the vibrations generated by the electrical components of the device during driving may cause the unmanned aerial vehicle body to roll over, thereby reducing the stability of the device during use. Summary of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a soil sampling unmanned aerial vehicle for hilly and mountainous areas. Through a lifting component, two ground inserting rods at the bottom surface of the unmanned aerial vehicle body can be lowered. When continuously lowered, the ground inserting rods can be inserted into the ground. The ground inserting rods inserted into the ground can greatly increase the grip of the unmanned aerial vehicle body, thereby increasing the stability of subsequent sampling. And by setting a rotating component, the two ground inserting rods can be driven to rotate, and then the soil where the ground inserting rods are inserted into the ground can be broken, so that the ground inserting rods are exposed in the external space, preventing the ground inserting rods from being inserted too firmly into the ground and causing the unmanned aerial vehicle body to be unable to take off.

[0007] To solve the above technical problems, the present utility model provides the following technical solution: A drone for soil sampling in hilly and mountainous areas, comprising a drone body. A protective shell is fixedly connected to the bottom surface of the drone body. A plurality of ground insertion rods are symmetrically arranged inside the protective shell.

The bottom end of the lifting rod is fixedly connected to the lifting block. The screw rod penetrates through the inside of the lifting block. The ground insertion rod is fixedly connected to the bottom surface of the lifting block.

[0009] Preferably, a first motor is installed on the bottom surface of the two rotating blocks. The output ends of the two first motors are respectively connected to the two screw rods. The bottom ends of the two screw rods are fixedly connected with limit blocks.

[0010] Preferably, the rotating assembly is composed of a driven gear, a driving gear, a belt, and a connecting rod. The two driven gears are rotatably arranged on the bottom surface of the drone body. The bottom surface of the driven gear is fixedly connected to the rotating block.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the following combines specific embodiments to further elaborate the utility model. However, the following embodiments are only the preferred embodiments of the utility model, not all. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the utility model.

[0023] Embodiment

[0024] Please refer to Figures 1-3As shown in the figure, the utility model provides a drone for soil sampling in hilly and mountainous areas, which includes a drone body 1. This device uses a drone as a commonly used sampling drone in the prior art, and will not be elaborated here. A protective shell 2 is fixedly connected to the bottom surface of the drone body 1. A hydraulic rod 14 is provided at the center inside the protective shell 2. The telescopic end of the hydraulic rod 14 is fixedly connected to an installation frame 15. Below the installation frame 15, there is a sampling cylinder 5 for sampling the soil in hilly and mountainous areas. A deflection assembly is provided between the installation frame 15 and the sampling cylinder 5. The deflection assembly is composed of a rotating rod 23, a fixed rod 22, and a deflection block 17. Among them, the fixed rod 22 is arranged inside the installation frame 15. The rotating rod 23 is inserted through the inside of the fixed rod 22, and the rotating rod 23 is fixedly connected to the fixed rod 22. The two ends of the rotating rod 23 are installed inside the installation frame 15, and the rotating rod 23 can rotate inside the installation frame 15. Thus, when the rotating rod 23 rotates, it can drive the fixed rod 22 fixedly connected to it to deflect. The bottom end of the fixed rod 22 is fixedly connected to the deflection block 17, and the bottom surface of the deflection block 17 is fixedly connected to the sampling cylinder 5. Thus, during use, the hydraulic rod 14 can drive the installation frame 15 to move downward, and the installation frame 15 drives the sampling cylinder 5 to move downward through the deflection block 17. When the sampling cylinder 5 is inserted into the soil inside the ground, the soil on the ground can be sampled. Two ear plates 24 are fixedly connected to both sides of the sampling cylinder 5, and an installation bolt 25 is inserted through the two ear plates 24, and the installation bolt 25 is connected to the deflection block 17. Thus, the ear plates 24 and the sampling cylinder 5 can be installed on the deflection block 17 through the installation bolt 25. By removing the installation bolt 25, the sampling cylinder 5 can be removed from the deflection block 17, which is convenient for the staff to pour out the soil inside the sampling cylinder 5. A second motor 16 is fixedly installed on one side of the installation frame 15 through a fixed frame, and the output end of the second motor 16 is connected to the rotating rod 23. Thus, by driving the second motor 16, the second motor 16 can drive the rotating rod 23 to rotate. When the rotating rod 23 rotates, it can drive the fixed rod 22 to deflect. When the fixed rod 22 deflects, it can drive the sampling cylinder 5 to deflect through the deflection block 17. After the soil sampling is completed, the sampling cylinder 5 can be deflected to an angle of 90° or greater than 90° with the installation frame 15, so as to prevent the soil inside the sampling cylinder 5 from falling from the opening;

[0025] When using this device, by controlling the UAV body 1, the device is landed at the designated sampling position, the hydraulic rod 14 is started, the hydraulic rod 14 drives the mounting frame 15 to move downward, the mounting frame 15 drives the deflection block 17 to move downward through the fixing rod 22, the deflection block 17 drives the sampling cylinder 5 to move downward. When the sampling cylinder 5 is inserted into the ground soil, the soil can be sampled. After sampling is completed, when the sampling cylinder 5 rises to the ground, the second motor 16 is started, the second motor 16 drives the rotating rod 23 to rotate, the rotating rod 23 drives the fixing rod 22 to deflect, the fixing rod 22 drives the deflection block 17 to deflect, and the deflection block 17 drives the sampling cylinder 5 to deflect, so that the included angle between the sampling cylinder 5 and the mounting frame 15 is 901° or greater than 90°, thereby preventing the soil inside the sampling cylinder 5 from falling from the opening of the sampling cylinder 5 during the flight of the UAV body 1;

[0026] As a further implementation manner of this embodiment, such as Figure 1 、 Figure 2 and Figure 4As shown in the figure, a plurality of ground insertion rods 9 for supporting the UAV body 1 are symmetrically arranged inside the protective case 2. The top end of the ground insertion rod 9 is connected with a lifting assembly, and the lifting assembly is composed of a rotating block 12, a lifting rod 10, a screw rod 7 and a lifting block 6. Among them, two rotating blocks 12 are symmetrically arranged inside the protective case 2, and the bottom surface of the rotating block 12 is symmetrically connected with a lifting rod 10. The bottom end of the lifting rod 10 is fixedly connected with a lifting block 6. A screw rod 7 is inserted through the inside of the two lifting blocks 6, and the screw rod 7 is threadedly connected with the lifting block 6. In this way, the lifting block 6 can be driven to move on the screw rod 7 by rotating the screw rod 7. Since the lifting rods 10 are symmetrically arranged on both sides of the screw rod 7, and both ends of the lifting rod 10 are respectively connected with the rotating block 12 and the lifting block 6. In this way, when the lifting block 6 moves, the lifting rod 10 can limit the moving direction of the lifting block 6, thereby preventing the lifting block 6 from rotating due to the rotation of the screw rod 7, ensuring the stability of the lifting block 6 during lifting. And the bottom surface of the lifting block 6 is fixedly connected with the ground insertion rod 9. In this way, when the lifting block 6 moves, the ground insertion rod 9 can be driven to move, so as to ensure that the ground insertion rod 9 is inserted into the bottom surface and ensure the stability of the UAV body 1. The bottom ends of the two screw rods 7 are fixedly connected with limit blocks 8, and the diameter of the limit block 8 is larger than that of the screw rod 7, so as to prevent the moving block from falling off the screw rod 7. The bottom surface of the two rotating blocks 12 is provided with a first motor 13, and the output ends of the two first motors 13 are respectively connected with the two screw rods 7. In this way, the screw rod 7 can be driven to rotate by driving the first motor 13. The bottom surface of the UAV body 1 is fixedly installed with an installation shell 3, and the installation shell 3 is communicated with the inside of the protective case 2. And a rotating assembly is arranged inside the installation shell 3, and the rotating assembly is composed of a driven gear 11, a driving gear 18, a belt 19 and a connecting rod 20. Among them, the two driven gears 11 are fixedly connected with the rotating block 12, and the driven gears 11 are arranged on the bottom surface of the UAV body 1 and are rotatably connected thereto. A driving gear 18 is meshed with one side of the two driven gears 11. The bottom surfaces of the two driving gears 18 are fixedly connected with a connecting rod 20. A belt 19 is connected between the two connecting rods 20 through a belt pulley. In this way, when one of the connecting rods 20 rotates, the connecting rod 20 can drive the other connecting rod 20 to rotate through the belt 19. A third motor 21 is arranged inside the installation shell 3, and the output end of the third motor 21 is connected with one of the rotating rods 23. In this way, by driving the third motor 21, one of the rotating rods 23 can be driven to rotate. A counterweight block 4 is arranged on the bottom surface of the UAV body 1. The counterweight block can make the counterweight on the bottom surface of the UAV body 1 uniform, so as to prevent the UAV body 1 from tilting during flight due to the counterweight being concentrated on one side;

[0027] When further using this device, start the first motor 13. The first motor 13 drives the screw rod 7 to rotate. The screw rod 7 drives the lifting block 6 to move downward. The lifting block 6 drives the ground-inserting rod 9 to move downward. When the ground-inserting rod 9 contacts the ground, the ground-inserting rod 9 can be continuously moved downward, so that the ground-inserting rod 9 can be inserted into the soil inside the ground. After the ground-inserting rod 9 is inserted into the ground, the firmness between the UAV body 1 and the ground can be increased to a great extent, so as to prevent the UAV body 1 from tipping over and shifting during subsequent soil sampling. When the sampling is completed and the UAV needs to return, the third motor 21 can be started at this time. The third motor 21 drives one of the connecting rods 20 to rotate. The connecting rod 20 drives the other connecting rod 20 to rotate through the belt 19. The two connecting rods 20 drive the driving gear 18 to rotate. The two driving gears 18 drive the driven gear 11 to rotate. The driven gear 11 drives the rotating block 12 to rotate. The rotating block 12 drives the lifting block 6 through the telescopic rod. The lifting block 6 drives the ground-inserting rod 9 to rotate inside the soil. The ground-inserting rod 9 during rotation can break the soil inserted by the ground-inserting rod 9, so that the two groups of ground-inserting rods 9 can be exposed, thus preventing the situation that the UAV cannot take off due to the ground-inserting rod 9 being inserted too deep and too firmly into the ground;

[0028] Specific working principle: By controlling the UAV body 1, the UAV body 1 is landed at the designated sampling position. When the UAV body 1 touches the ground, the first motor 13 can be started. The first motor 13 drives the screw rod 7 to rotate, the screw rod 7 drives the lifting block 6 to move downward, the lifting block 6 drives the ground inserting rod 9 to move downward. By continuously moving the ground inserting rod 9 downward, the ground inserting rod 9 can be inserted into the ground, thereby increasing the grip of the UAV body 1 on the ground and facilitating that the UAV body 1 does not roll over during the subsequent sampling process. By starting the hydraulic rod 14, the hydraulic rod 14 drives the mounting frame 15 to move downward, the mounting frame 15 drives the deflection block 17 to move downward through the fixing rod 22, and the deflection block 17 drives the sampling cylinder 5 to move downward. When the sampling cylinder 5 is inserted into the ground soil, the soil can be sampled. After the sampling is completed, the sampling cylinder 5 is recovered to the ground, and the second motor 16 is started. The second motor 16 drives the rotating rod 23 to rotate, the rotating rod 23 drives the fixing rod 22 to deflect, the fixing rod 22 drives the deflection block 17 to deflect, and the deflection block 17 drives the sampling cylinder 5 to deflect, so that the included angle between the sampling cylinder 5 and the mounting frame 15 can be deflected to 90° or greater than 90°, thereby preventing the sample inside the sampling cylinder 5 from falling during the flight of the UAV body 1. By starting the third motor 21, the third motor 21 drives one of the connecting rods 20 to rotate, the connecting rod 20 drives the other connecting rod 20 to rotate through the belt 19, the two connecting rods 20 drive the driving gears 18 to rotate, the two driving gears 18 drive the two driven gears 11 to rotate, the driven gears 11 drive the lifting block 6 to rotate through the telescopic rod, and the lifting block 6 drives the ground inserting rod 9 to rotate. The rotating ground inserting rod 9 can break the soil inserted into the ground, so that the ground inserting rod 9 is exposed, thereby preventing the situation that the UAV body 1 cannot take off due to the ground inserting rod 9 being inserted too deep and too firmly into the ground.
