Embodiment 1
[0027] A kind of coupling type soil sampling pipe provided in this embodiment has a structure such as figure 2 and image 3 As shown, it includes a sampling tube 1, a matching tube 4 and a sampling head 5. The sampling tube 1 adopts a non-smooth surface, and its upper end is provided with a screw device 10 along the axial direction. The sampling tube 1 and the matching tube 4 have The extended groove, the matching pipe 4 is movable and fixed on the sampling pipe 1, so that the two grooves are relatively arranged to form a cavity, and the PVC pipe 2 is arranged inside the cavity; the sampling head 5 is connected to the lower end of the sampling pipe 1 by threads, The inner contour of the sampling head 5 is an inverted cone structure, and its diameter is smaller than that of the sampling pipe 1, so that the sampling pipe head 5 and the sampling pipe 1 form an inward convex structure, and at the same time, the sampling head 5 communicates with the PVC pipe 2 inside the cavity. ...

The invention relates to an oppositely assembled soil sampling tube which is convenient to dismantle and has a manpower saving effect. The soil sampling tube comprises a sampling tube body, an oppositely assembled tube and a sampling head, wherein the sampling tube body and the oppositely assembled tube comprise grooves which extend along the length direction; the oppositely assembled tube is movably fixed on the sampling tube body, so that the two opposite grooves form a cavity; a polyvinyl chloride (PVC) tube is movably arranged inside the cavity; the sampling head is fixedly arranged at the lower end part of the sampling tube body and communicated with the PVC tube. The oppositely assembled soil sampling tube is ingenious in conception, and simple in structure; the contact area of the sampling tube body and a sampling soil column is effectively reduced by an inwards convex structure formed by an inverted cone-shaped sampling head and the sampling tube body, the frictional resistance of the sampling tube body and the sampling soil column is reduced, and thus the collection of the soil column is facilitated. The soil sampling tube is convenient to dismantle and high in sampling efficiency, and labor force of an operator can be effectively saved.
Description
technical field [0001] The invention relates to a coupling type soil sampling tube, in particular to a coupling type soil sampling tube which is easy to disassemble and saves manpower. Background technique [0002] The implementation of precision agriculture mainly includes three links: collection of farmland information, information management and decision-making, and variable operation. The development of precision agriculture is supported by the rapid and accurate acquisition and processing of farmland spatial distribution information. The link of farmland information collection is an important basis for the implementation of precision agriculture. However, the backwardness of field information collection technology has become one of the main obstacles to the implementation of precision agriculture. Therefore, the development of field information collection technology is the premise and basis for the development of precision agriculture. Among them, the rapid and accurate...
