The utility model aims to provide a soil sampling device to solve the problem that the sampling device is inconvenient to use.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a soil sampling device, includes the guide holder, the symmetry is provided with the connecting hole on the guide holder, the inboard slip of connecting hole is provided with the spliced pole, the lower extreme welding of spliced pole has the base, the guide holder has the sampling tube with the inboard grafting of base, it is provided with the lifting ring to slide on the sampling tube, the lower extreme of lifting ring is connected with the guide holder.

Preferably, the symmetry is provided with the rotation groove on the guide holder, rotates the inboard pivot of groove and is connected with the ejector pin, and the lower extreme and the base contact of ejector pin push down the ejector pin, through the downward butt base of ejector pin, with the ascending lifting of guide holder to drive lifting ring and sampling tube rebound through the guide holder, with this convenience extract the sampling tube from soil.

Preferably, the symmetry is provided with the mounting groove on the lifting ring, and the inboard slip of mounting groove is provided with the locating pin, is provided with the spring between locating pin and the mounting groove, and it is inboard to promote the locating pin through the elasticity of spring and insert the constant head tank, prevents that the locating pin from the inboard roll-off of constant head tank.

Preferably, the last symmetry of sampling tube is provided with the constant head tank, and the inboard locating pin of pegging graft of constant head tank has inserted the constant head tank inboard and fixes a position the lifting ring.

Preferably, be provided with the footboard on the sampling tube, the setting up of footboard is conveniently taken a sample with the foot in pushing the sampling tube into soil.

Preferably, a scale is arranged on the sampling tube, and the sampling depth is determined by referring to the scale.

Preferably, threaded connection has a positioning bolt on the guide holder, and positioning bolt inwards extrudes the sampling tube and fixes a position the sampling tube.

Compared with the prior art, the utility model has the beneficial effects that: when the utility model is used, the verticality during sampling can be ensured by arranging the base and the guide seat; the position of the lifting ring is adjusted by using the scale, so that the sampling depth is conveniently determined; the sampling tube is convenient to pull out from the soil by abutting the lower pressing rod against the guide seat to drive the lifting ring.
