[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0021] See Figure 1 This application provides a portable exploration and sampling device, including a support frame 1, a main rod 2, and a sampling head 3. The support frame 1 includes a support body 11 and a lifting assembly 12. The lifting assembly 12 is connected to the bottom end of the support body 11. The main rod 2 is movably connected to the support body 11. The top of the support body 11 is provided with a drive motor 4. The top end of the main rod 2 is connected to the output end of the drive motor 4 through a coupling. The sampling head 3 is connected to the bottom end of the main rod 2 through a connecting assembly 5.

[0022] See Figures 2-3 Specifically, the landing assembly 12 includes a landing plate 121 and a mating groove 122 formed on the bottom side of the support body 11. The landing plate 121 is disposed in and rotatably connected to the mating groove 122. A rotating shaft 123 is connected to the bottom end of the landing plate 121, and the rotating shaft 123 is rotatably connected to the side wall of the mating groove 122. The landing plate 121 rotates with the mating groove 122 via the rotating shaft 123, facilitating the entry and exit of the landing plate 121 into and out of the mating groove 122.

[0023] See Figures 2-3 Specifically, the landing plate 121 has a fixing hole 124 in the middle and a slot 125 at the top. The fixing hole 124 is connected to a fixing member 126. A buckle 127 is provided in the mating groove 122, and the buckle 127 is engaged with the slot 125. After the buckle 127 and the slot 125 are engaged, the landing plate 121 can be stored and fixed in the mating groove 122, reducing the overall size of the device. During sampling, the fixing member 126 is installed into the fixing hole 124 to fix the landing plate 121 to the ground, thereby forming a more stable support.

[0024] See Figure 3 Specifically, the bottom end of the support base 1 is provided with a receiving groove 128, which is located within the mating groove 122. The receiving groove 128 contains an accessory box 129. The receiving groove 128 is used to place the accessory box 129, and the accessory box 129 is used to store the fastener 126.

[0025] See Figure 4Specifically, the sampling head 3 is a hollow cylindrical structure. The bottom end of the sampling head 3 is provided with cutting saw teeth 31, and the inner and outer walls of the cylinder are provided with threaded teeth 32. The threaded teeth 32 can reduce the resistance of the soil layer to the sampling head 3 during sampling and reduce the load on the device.

[0026] See Figure 4 Specifically, the connecting assembly 5 includes a connecting plate 51, which is disposed at the bottom end of the main rod 2. An installation head 52 is fixedly connected to the connecting plate 51. An internal threaded hole 53 is provided in the installation head 52. A threaded connector 54 is provided at the top of the sampling head 3. The threaded connector 54 is connected to the internal threaded hole 53 by threaded engagement.

[0027] The working principle of this utility model:

[0028] When the device is not in use, the fastener 126 is stored in the accessory box 129, and the accessory box 129 is placed in the receiving slot 128. Then, all the landing plates 121 are snapped into their corresponding mating slots 122, and the landing plates 121 are fixed by the buckles 127 and the slots 125, thus completing the storage and assembly of the landing assembly 12, reducing the outward volume of the frame and improving the neatness of the device. Afterward, the sampling head 3 is removed from the mounting head 52 to reduce the weight of the device and facilitate carrying.

[0029] When the work is required upon arrival at the destination, the sampling head 3 is inserted into the mounting head 52. Then, the lifting plate 121 is pulled out from the mating groove 122, the fixing piece 126 is removed, and the fixing piece 126 is assembled into the fixing hole 124. The fixing piece 126 is driven into the ground until the lifting plate 121 is fixed to the ground, thus forming a more effective support. Then, the drive motor 4 is started to drive the main rod 2 to rotate, which drives the sampling head 3 to drill into the ground. During this process, the resistance is reduced by the threaded teeth 32 set on the inner and outer walls of the sampling head 3, and the inner spiral pattern can stabilize the soil sample that has entered the sampling head 3 and prevent the soil sample from falling out, thus completing the sampling.

[0030] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
