Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and 2, a soil collection device for environmental monitoring comprises a collection cylinder 1, an internal thread cylinder 2, a sampling rod 3 and a drill bit 4; the two ends of the collecting cylinder 1 are open and the interior of the collecting cylinder is hollow, and an internal thread cylinder 2 is arranged at the front section of the inner cavity of the collecting cylinder 1; the sampling rod 3 comprises a thread section 30 and a spiral section 31, the thread section 30 is in threaded connection with the internal thread cylinder 2, and a spiral blade 32 is arranged on the spiral section 31;
the bottom end of the spiral section 31 is connected with the drill bit 4, the top end of the spiral section 31 is connected with the bottom end of the thread section 30, and a certain distance is reserved between the top end of the spiral section 31 and the internal thread cylinder 2;
the top end of the thread section 30 extends outwards to extend out of the inner cavity of the collecting cylinder 1, and the extending tail end is provided with an adjusting part 5; the sampling tube 1 is provided with a sampling passage 6 corresponding to the blade 32 in a penetrating way, and the sampling passage 6 is internally detachably and fixedly connected with a sample collecting part 7.
It should be noted that a certain distance between the top end of the spiral section 31 and the internally threaded cylinder 2 is necessary to ensure that the blade 32 can bring the collected sample to the sample outlet 6 during the reverse rotation.
