Drawings
Fig. 1 is a schematic structural view of the present utility model. In the figure: the sampling device comprises a sampling tip cone 1, an external thread 2, a one-way valve 3, a connecting pipe body 4, a handle 5, an internal thread 6 and a sampling structure 7.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Embodiments of the present utility model are intended to be within the scope of the present utility model as defined by the appended claims.
Referring to fig. 1, it is shown that: the utility model provides a portable soil sampling instrument of no disturbance, it includes sampling point awl 1, check valve 3, links body 4, handle 5, internal thread 6 and sampling structure 7, the one end of linking body 4 with sampling point awl 1 between threaded connection, the other end with sampling structure 7 between threaded connection, the body both sides of linking body 4 install handle 5, the body front end of linking body 4 be provided with check valve 3.
The bottom of the sampling tip cone 1 is provided with an external thread 2, and both ends of the connecting pipe body 4 are provided with internal threads 6. The front end of the connecting pipe body 4 is a circular pipe with internal threads and can be connected with the tail part of the sampling tip cone 1,
the tail part of the connecting pipe body 4 also adopts an internal thread design, and can be used for directly connecting the connecting sampling structure 7.
The tail part of the sampling tip cone 1 is a circular tube with external threads and is combined with the circular tube; the front end of the connecting pipe body 4 is a circular pipe with internal threads and can be connected with the tail part of the sampling tip cone 1,
the connecting pipe body 4 adopts a reducing structure, the front end is of a circular pipe structure matched with the sampling tip cone 1, and the rear end is of a cylindrical structure matched with the sampling structure 7. The purpose of reducing is mainly to enable front soil to smoothly slide into a sampling structure connected at the rear after entering a large space, so that the purpose of undisturbed sampling is realized.
