In addition, a first handle 103 is further disposed at the upper end of the outer wall of the first sampling tube 100.
The transmission part is arranged in the first sampling barrel 100 and comprises a bearing 201, a connecting rod 202, a fixing plate 203 and a transmission rod 204, the connecting rod 202 is connected to the lower surface of the outer ring of the bearing 201, the fixing plate 203 is connected to the bottom end of the connecting rod 202, the bottom end of the transmission rod 204 is inserted into the bore of the inner ring of the bearing 201 and is fixedly connected with the inner ring of the bearing 201, the upper end of the transmission rod 204 penetrates through the sealing plug 101 and is in threaded connection with the sealing plug 101, and it is obvious from fig. 1 and fig. 3 that a section of thread line 2041 is arranged at the upper end of the transmission rod 204 and is used for being matched with a. In addition, a second handle 205 is arranged on the top of the transmission rod 204.
Two ends of the hinge rod 300 are respectively hinged with a fixing seat, wherein one fixing seat is fixed on the inner wall of the sealing plate 500, and the other fixing seat is fixed on the lower surface of the fixing plate 203; as can be seen from fig. 5 and 6, the fixing base comprises 2 supporting plates 601 and 1 polish rod 602, and the 2 supporting plates 601 are connected together through the polish rod 602. The hinge rod 300 is hinged to the fixing base in a manner that two ends of the hinge rod 300 are respectively provided with a hinge hole 301 matched with the polish rod 602, and the polish rod 602 is inserted into the hinge holes 301. In addition, in order to prevent the hinge rod 300 from touching the side wall of the first sampling tube 100 during the soil sampling process, the fixing seat on the sealing plate 500 is arranged at the middle upper part of the sealing plate 500 and close to the middle part of the sealing plate 500; the fixing seat on the fixing plate 203 is arranged at the middle position from the circle center to the periphery of the fixing plate 203.
The second sampling tube 400 is a hollow structure with an open upper end, and the upper end of the second sampling tube 400 is screwed on the lower end of the first sampling tube 100. The bottom of the second sampling tube 400 extends downward in a conical shape.
In the embodiment, a stop ring 206 is fixed on the transmission rod 204, and the stop ring 206 is located at the top of the thread line 2041. The upper end of the outer wall of the sealing plate 500 is provided with a limiting plate 501. The outer wall of the first sampling barrel 100 is provided with scale marks 104.
