[0021] The utility model makes further illustration through specific embodiment combining with drawings below, but not to limit the utility model, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be contained in the protection scope of the utility model. Embodiment

[0022] The portable soil sampling device provided by the embodiment comprises a drill cylinder 1 arranged vertically and having an opening downward, and the top of the drill cylinder 1 is in a sealed structure, and preferably, the bottom of the drill cylinder 1 is provided with a plurality of sawteeth. Figure 1 The drill cylinder 1 is used for inserting into soil, and the sawteeth can make the drill cylinder 1 more easily inserted into soil, and in the process of insertion, soil can enter the inside of the drill cylinder 1, so that the purpose of sampling soil is achieved.

[0023] As shown in Figure 1 and Figure 4 , a sleeve 5 is arranged vertically outside the drill cylinder 1, and the outer diameter of the drill cylinder 1 is smaller than the inner diameter of the sleeve 5.

[0024] As shown in Figure 1 and Figure 4 , a limiting ring 2 is sleeved on the upper end of the drill cylinder 1, and the inner side wall of the limiting ring 2 is fixed on the outer side wall of the drill cylinder 1.

[0025] As shown in Figure 1 and Figure 3 , the top and bottom of the limiting ring 2 are provided with connecting assemblies for fixing the sleeve 5; the connecting assemblies comprise external threads, and the external threads are arranged on one end of the sleeve 5 with an opening; the top and bottom of the limiting ring 2 are provided with annular grooves, and the annular grooves are provided with internal threads for threadedly cooperating with the external threads. Figure 1 According to the orientation in , one end of the sleeve 5 with an opening is the lower end of the sleeve 5, and because the external threads are arranged on the lower end of the sleeve 5, when the external threads on the sleeve 5 are in contact with the internal threads in the annular groove on the top of the limiting ring 2, the lower end of the sleeve 5 can be fixed in the annular groove on the top of the limiting ring 2, so that the sleeve 5 is fixed in the upward direction of the drill cylinder 1; then by operating the sleeve 5 to move, the drill cylinder 1 can be driven to move, so that the drill cylinder 1 can be moved into soil; thus, by the design of the sleeve 5, the drill cylinder 1 can be more easily and conveniently operated to enter soil to achieve the purpose of convenient sampling. Figure 3The bottom of the limiting ring 2 is provided with an annular groove, and the annular groove is internally threaded. When the sampling is completed, the sleeve 5 is removed from the internal thread at the top of the limiting ring 2, and then the sleeve 5 is turned over with the opening upward. Therefore, the external thread at the upper end of the sleeve 5 can be screwed on the internal thread at the bottom of the limiting ring 2. When the sleeve 5 is fixed in the annular groove at the bottom of the limiting ring 2, because the inner diameter of the sleeve 5 is larger than the outer diameter of the drill cylinder 1, the sleeve 5 can be sleeved on the drill cylinder 1. Through the design that the sleeve 5 is sleeved on the outer side of the drill cylinder 1, the sleeve 5 can be stored on the outer side of the drill cylinder 1. After the sampling is completed or before the sampling, the sleeve 5 is conveniently stored. Compared with the sleeve 5 being installed at the top of the drill cylinder 1, the occupied area of the sleeve 5 can be reduced, so that the sleeve 5 and the drill cylinder 1 are conveniently carried during carrying, and thus the carrying burden is reduced.

[0026] In the implementation, the connecting assembly can also be replaced by a screw. A convex ring is sleeved on the end of the sleeve 5 with the opening. The convex ring is provided with a threaded hole that is in threaded cooperation with the screw hole. The top and the bottom of the limiting ring 2 are provided with threaded blind holes that are in threaded cooperation with the threaded hole. Then the screw is screwed into the threaded hole and the threaded blind hole, so that the sleeve 5 is fixed on the limiting ring 2.

[0027] As shown in Figure 1 and Figure 2 , the sleeve 5 is provided with a through hole 4 for the foot to pass through. The through hole 4 is in left-right communication, so that the through hole 4 is in internal-external communication on the left side and the right side of the sleeve 5. In use, the foot is stepped into the two through holes 4. When the foot is stepped down, the sleeve 5 is driven to move downward, so that the drill cylinder 1 is driven to move downward. Therefore, when the drill cylinder 1 is working, the drill cylinder 1 can be more easily pushed into the soil.

[0028] As shown in Figure 1 and Figure 3 , the sleeve 5 is provided with a first through hole that is in upward-downward communication and is away from the end with the opening. The first through hole is independently provided with a supporting rod 8. The sleeve 5 is provided with a limiting plate 7. One end of the supporting rod 8 is fixed on the limiting plate 7, and the other end of the supporting rod 8 passes through the first through hole and is located on the outer side of the sleeve 5. The sleeve 5 and the limiting plate 7 are provided with a second through hole that is in left-right communication. The second through hole is provided with a plug rod 6 for locking the limiting plate 7. The end of the sleeve 5 away from the end with the opening is Figure 1The upper end of the sleeve 5 is sealed. Since both the sleeve 5 and the limiting plate 7 have second through holes that connect the left and right sides, when one end of the insertion rod 6 passes through the second through hole on the right side of the sleeve 5 into the second through hole on the limiting plate 7, and then exits through the second through hole on the limiting plate 7 into the second through hole on the left side of the sleeve 5, the limiting plate 7 can be fixed on the sleeve 5, thus locking its position. During use, the sampling personnel manually operate the support rod 8 to move the sleeve 5 and the drill barrel 1 to the required position. To sample the soil, place the drill cylinder 1 on the soil. Hold the support rod 8 by hand while stepping into the perforation 4 on the sleeve 5. This allows you to push the drill cylinder 1 into the soil using a combination of hand and foot movements, making it easier to move. After sampling, because the insertion rod 6 is inserted into the second through hole of the limiting plate 7 and the sleeve 5, removing the insertion rod 6 from these holes allows the limiting plate 7 to move, thus moving the support rod 8 along with it. At this point, according to... Figure 3 When the sleeve 5 is fixed to the outside of the drill barrel 1, the limiting plate 7 and the support rod 8 can move into the inside of the drill barrel 1. After the insertion rod 6 is reinserted into the second through hole on the sleeve 5, the insertion rod 6 can also prevent the limiting plate 7 and the support rod 8 from falling out of the first through hole on the sleeve 5 under the action of gravity. Therefore, through the above design, it is also convenient to store the limiting plate 7 and the support rod 8, and the area occupied by the limiting plate 7 and the support rod 8 can be reduced during the carrying process, so as to achieve the purpose of convenient carrying.

[0029] like Figure 1 As shown, a first handle 9 is fixed on the support rod 8 located on the outside of the sleeve 5. The design of the first handle 9 makes it easier and more convenient to move the support rod 8.

[0030] like Figure 1 As shown, the support rod 8 is a telescopic rod, which consists of two hollow rods, an upper and a lower one. The diameter of the lower hollow rod is slightly larger than that of the upper hollow rod. The lower hollow rod has a threaded hole that is open to both the inside and outside, and a fastening screw that is threaded into the threaded hole is installed in the threaded hole. Therefore, when the upper hollow rod is inserted into the lower hollow rod, the upper hollow rod can be locked in the lower hollow rod by tightening the fastening screw. Thus, through the above design, the length of the support rod 8 can be adjusted, making it convenient for users of different heights to operate.

[0031] like Figure 3 As shown, a second handle 3 is fixed to the top of the drill barrel 1. When the sleeve 5 is stored on the outside of the drill barrel 1, the drill barrel 1 can be carried by operating the second handle 3 by hand, thus providing a certain degree of convenience during use; at the same time, this design can also be carried in a backpack.

[0032] like Figure 4As shown, the drill cylinder 1 is provided with a through slot along its length direction, which is communicated with the bottom of the drill cylinder 1, and the through slot is arranged at the front side of the drill cylinder 1. When the drill cylinder 1 is taken out from the soil, part of the soil can enter into the drill cylinder 1 to achieve the sampling purpose. At this time, the soil can be taken out from the drill cylinder 1 through the through slot.

[0033] In the specific use process: first, as shown in the orientation of Figure 1 , the first handle 9 on the supporting rod 8 is operated by hand, and the foot is stepped on the perforation 4 on the sleeve 5. Then, the soil can be taken out from the drill cylinder 1 through the through slot on the drill cylinder 1. After the sampling is completed, as shown in the orientation of Figure 3 , the sleeve 5 is disassembled from the top position of the limiting ring 2. Then, the sleeve 5 is inverted, and the sleeve 5 is sleeved on the outside of the drill cylinder 1, and the upper end of the sleeve 5 is fixed in the annular groove at the bottom of the limiting ring 2. Then, the insertion rod 6 is pulled out from the second through hole on the limiting plate 7 and the sleeve 5, so that the limiting plate 7 is not limited. The limiting plate 7 and the supporting rod 8 can enter into the drill cylinder 1 to achieve the storage purpose. Finally, the insertion rod 6 is inserted into the second through hole on the sleeve 5, so that the limiting plate 7 and the supporting rod 8 are prevented from falling out of the drill cylinder 1. In this use process, before or after use, the sleeve 5 can be stored on the outside of the drill cylinder 1, and the supporting rod 8 and the limiting plate 7 are stored in the inside of the drill cylinder 1. Therefore, the occupied area of the sleeve 5, the supporting rod 8 and the limiting plate 7 is reduced, so that the design is convenient to carry and the carrying burden is reduced.
