DETAILED DESCRIPTION

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] See attached Figure 1 -Attached Figure 5 A soil sampling device includes a drilling device 200, which is used to drill holes in a predetermined soil surface to loosen the surrounding soil and thus achieve soil sampling; during the drilling process, a reaction force is generated on the device, resulting in poor stability of the device, especially when drilling on a slope surface, the entire device is prone to shaking, affecting the drilling and subsequent soil sampling operations.

[0025] In order to solve the above problems, a supporting device 100 is arranged on the outside of the drilling device 200, and the supporting device 100 here includes a first supporting frame 110, a second supporting frame 120 rotatably connected to the inside of the first supporting frame 110, and the drilling device 200 is installed at the lower end of the second supporting frame 120. The side wall of the first supporting frame 110 is fixed with a third supporting frame 130 located on the outside of the drilling device 200. The cross-section of the third supporting frame 130 is U-shaped, and a supporting assembly 400 is arranged at the U-shaped opening of the third supporting frame 130. The supporting assembly 400 is rotatably connected to the side wall of the first supporting frame 110, and a torsional elastic member is installed at the rotating connection.

[0026] The above-mentioned torsion elastic member can be selected as a torsion spring, through which the supporting assembly 400 as a whole can be in a state of contraction toward the inside; during the drilling operation, both ends of the U-shaped third supporting frame 130 are in contact with the slope surface to achieve support; at the same time, the supporting assembly 400 on the lower inclined side is pressed against the ground, which has a stable supporting effect. The combination of the third supporting frame 130 and the supporting assembly 400 can maintain the stability of the first supporting frame 110 and the second supporting frame 120 located in the middle position, thereby ensuring the stability of the drilling device 200 during the drilling process, assisting manual positioning, reducing the workload of staff, ensuring the safety of the drilling operation, and also improving the efficiency of the drilling operation and subsequent soil sampling.

[0027] Please refer to the attached Figure 2 Specifically, the bearing assembly 400 here includes a first bearing plate 410 rotatably connected to the first bearing frame 110, and an elastic rotating joint 420 is arranged on the side of the first bearing plate 410 away from the first bearing frame 110, and a second bearing plate 430 is fixed to the rotating end of the elastic rotating joint 420. The above-mentioned elastic rotating joint 420 can be selected as a combination of a positioning frame, a positioning shaft and a torsion spring. The second bearing plate 430 can further improve the bending state of the first bearing plate 410, so that the bottom surface of the second bearing plate 430 can be completely in contact with the ground, so as to increase the support area and further ensure the stability of the inclined support.

[0028] Please refer to the attached Figure 4 Here, a limit assembly 500 located on the rotation path of the first carrier plate 410 is installed on the side wall of the first carrier frame 110. The limit assembly 500 limits the rotation range of the first carrier plate 410, allowing the limit assembly 500 to rotate within a predetermined range, which can avoid the overall flipping exceeding a predetermined angle and ensure that the first carrier plate 410 is in a predetermined tilted state. By pressing down the first carrier plate 410, the first carrier plate 410 can be automatically unfolded, thereby improving the layout efficiency.

[0029] Furthermore, the first supporting plate 410 is rotatably connected to the first supporting frame 110 through a rotating sleeve 510, and the limiting assembly 500 includes a first limiting protrusion fixed to the side wall of the rotating sleeve 510, a second limiting protrusion 520 fixed to the first supporting frame 110 is provided on the first side of the first limiting protrusion, and a limiting sleeve 530 fixed to the second supporting frame 120 is provided on the second side of the first limiting protrusion. The first supporting frame 110 and the second supporting frame 120 can be driven and controlled by a motor, and the first supporting frame 110 can maintain a relatively consistent slope with the third supporting frame 130; at the same time, the second supporting frame 120 can be driven and controlled to be in a horizontal state, so that the drilling device 200 is in a vertical state and drills downward, avoiding the application of a reaction force toward the outside to the drilling device 200, further ensuring the stability of the drilling construction, reducing the difficulty of soil sampling and further improving the efficiency of soil sampling.

[0030] See attached Figure 3 Specifically, the drilling device 200 includes a drilling shaft 220 and a driving device 240 for controlling the rotation of the drilling shaft 220. A drilling casing 210 is sleeved on the outer side of the drilling shaft 220. The drilling casing 210 also includes a telescopic element 230 for controlling the linear movement of the drilling casing 210. During the drilling process, the driving device 240 controls the drilling shaft 220 to drive the drilling casing 210 to rotate continuously. At the same time, during the rotation process, the telescopic element 230 controls the drilling casing 210 to extend toward the soil direction to achieve drilling sampling of the soil. In order to ensure that the above structure is During normal operation, a linkage groove 221 is opened on the surface of the drilling shaft 220, and a linkage protrusion located in the linkage groove 221 is opened on the inner wall of the drilling casing 210 to ensure that the drilling casing 210 and the drilling shaft 220 can rotate synchronously during the extension and retraction process; and a rotating connecting piece 250 is installed on the surface of the drilling casing 210, and the lower end of the rotating connecting piece 250 is rotatably connected to the upper surface of the drilling casing 210, and the telescopic element 230 is fixedly connected to the surface of the rotating connecting piece 250, so that the extension and retraction of the drilling casing 210 during rotation can be controlled by the telescopic element 230.

[0031] Furthermore, a negative pressure dust suction device 300 is installed on the side wall of the supporting component 400 toward the drilling device 200. The negative pressure dust suction device 300 includes a negative pressure hood, a telescopic part for controlling the telescopic movement of the dust suction hood, and a rotating element for controlling the rotation of the telescopic part. Through the cooperation of the telescopic part and the rotating element, the negative pressure hood can be moved toward the direction of the drilling hole to automatically sample the soft soil on the surface, thereby reducing the burden of soil sampling on the staff, realizing automatic soil sampling and collection, and improving the efficiency of soil sampling.

[0032] A drone sampling device includes the soil sampling device mentioned above and also includes a flying device 600. The flying device 600 is detachably connected to the soil sampling device. The drone sampling device can be used in complex unmanned areas, and is particularly suitable for sampling on a soil surface with a certain inclination. The specific sampling process is as follows: first, the soil sampling device is installed on the lower end of the flying device 600, and the flying device 600 carries the soil sampling device to fly to a predetermined inclined surface. At the same time, one side of the bearing component 400 is controlled to face a lower inclined side. In the process of the soil sampling device being fitted with the ground, it is automatically unfolded under the action of squeezing, and can play a good supporting role from below. At the same time, the drilling device 200 can be electrically controlled to deflect, so that the drilling device 200 is in a vertical state to drill holes in the soil, thereby ensuring stability during the drilling sampling process.

[0033] Through the above-mentioned settings, it is possible to carry out soil sampling in remote and harsh environments and realize automated sampling operations, which greatly improves the efficiency of soil sampling by staff; by setting up an automatically unfolded supporting component 400 and adjusting the drilling direction of the drilling device 200, the continuous stability of the soil sampling process is ensured.

[0034] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
