The utility model adopts the technical proposal that: a soil detection sampling device comprises a sampling cylinder, a sampling column and a sleeve; the two ends of the sampling cylinder are open, the outer surface of the sampling cylinder is provided with a helical blade, the upper part of the inner wall of the sampling cylinder is provided with a helical guide groove, the lower part of the inner part of the sampling cylinder is a smooth inner wall, and the upper end of the sampling cylinder is fixedly connected with a turntable; the sampling column is a threaded column, threads are arranged on the outer surface of the other cylindrical parts of the sampling column except the smooth part at the upper end of the sampling column, the lower end of the sampling column is a conical head, the smooth part at the upper end of the sampling column is fixedly connected with a handle, and a sleeve is sleeved on the handle; the spiral guide groove in the sampling tube is matched with the thread of the sampling column, and the sampling column is spirally inserted in the sampling tube in a connection state.
Further, the helical blade of the outer surface of the sampling tube is arranged at the lower part of the sampling tube, and the end part of the lower end of the sampling tube is in a shape of a cone frustum.
Further, the inner diameter of the smooth inner wall part of the lower part of the sampling cylinder is equal to the outer diameter of the thread of the sampling column.
Further, the sleeves sleeved on the sampling column handle are a series of sleeves with different length and size.
Furthermore, the turntable on the sampling tube is fixedly connected with the upper part of the sampling tube through a cylindrical rib.
Furthermore, the anti-skid sleeves are uniformly arranged on the rotating disc ring column at intervals.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model adopts the spiral drilling to sample, which saves labor and time; the sampling tube is screwed with the sampling column and then inserted into soil, the sampling column is screwed in twice when the sampling tube is drilled to a certain depth, the purity of the sample is ensured, and the detection accuracy is improved.
2. Whole structure operation range is little, avoids moving a worker on a large scale, and convenient quick acquisition soil sample.
3. Simple structure, convenient operation, the sampling tube includes the sampling column, conserves the sample in the sampling tube between the sampling column screw thread after the sample, guarantees not drop or by secondary pollution with the process sample that whole structure took out from soil.
4. The sleeve that the sampling post upper end cup jointed is equipped with the model of different length, can choose for use as required, and convenient quick sample.
5. The first precession and the second precession of the whole mechanism are both through a spiral structure, and a sample with a harder barrier sampling point can be drilled with smaller force.
6. The lower end of the sampling tube is in a cone frustum shape, so that the sampling tube can be conveniently drilled into the sampling tube during sampling. The sampling tube upper end is the carousel, and when the sampling tube bored into certain degree of depth, when the sample column secondary precession, the carousel can prevent that the sampling tube from continuing to give the sample column holding power when deep into soil.
