Detailed Description

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.

In this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

As described in the background art, the conventional sampling method is that a worker peels the soil at the upper part by a shovel, and then fills the peeled soil into a collection bag by the shovel, thereby completing the sampling; however, such a collection method is complicated, and the shovel is used to peel off the upper soil layer and then fill the soil, so that the middle soil layer is easy to be polluted (particularly, the soil with the microbial inoculum is easy to be polluted, and the soil properties of the upper layer are different from those of the middle soil layer, if the soil falls into the upper thin soil during sampling, the subsequent study on the soil is easy to be interfered with), if other tools are used to fill the peeled soil layer, tools are additionally added, so that two or more tools are carried by the staff during sampling, and the burden of the staff is increased.

For the above reasons, as shown in fig. 1 to 4, the present embodiment discloses a collecting device for soil having microbial agents, comprising a collecting tube 100 and a drill bit 300 connected to the bottom of the collecting tube 100,

the collecting tube 100 is internally provided with a containing cavity 101, the outer wall of the collecting tube 100 is provided with a collecting hole 103 communicated with the containing cavity 101, one side edge of the collecting hole 103 is provided with a convex stripping part 102, and the glass part 102 extends and is convex along the tangential direction of the collecting tube, as shown in fig. 4.

In the process, the drill bit penetrates through the thin soil on the surface, and in the process of puncturing, the collecting pipe does not rotate, so that the stripping part cannot be brought into the accommodating cavity.

In order to facilitate the drainage of the soil in the receiving cavity, as shown in fig. 6 to 9, in an embodiment, a drainage hole 104 communicating with the receiving cavity 101 is formed at the bottom of the collecting tube 100, and the drill 300 is mounted to the drainage hole 104. During discharging, the drill bit is disassembled, and then the soil is poured out of the discharging hole.

In order to facilitate the insertion of the drill bit into the soil, as shown in fig. 10, in one embodiment, the drill bit 300 includes a tapered ground breaking portion through which the insertion of the drill bit into the soil is facilitated, and in order to facilitate the connection of the drill bit with the sampling tube, a connection portion 302 is provided at an upper end of the ground breaking portion, and the connection portion is inserted into the discharge hole for connection. Preferably, the connecting part is connected with the discharging hole in a threaded mode. The connecting portion is provided with external threads, and the discharging hole is provided with internal threads. To facilitate the penetration of the drill bit into the soil, in one embodiment, the tapered surface of the ground breaking portion is provided with a spiral rib 301.
