As a further scheme of the utility model, a screw rod penetrates through the bottom of the sampling tube, a screw hole is formed in the center of the upper surface of the fixing seat, and the screw rod is in threaded fit with the screw hole.

As a further scheme of the utility model, the top end of the screw rod is fixedly connected with a piston in the sampling tube, and the piston is adaptively matched with the inner wall of the sampling tube.

As a further scheme of the utility model, a groove is formed in the outer surface of the screw, and a convex strip matched with the groove is arranged on the contact surface of the sampling tube and the screw.

As a further scheme of the utility model, a handle is fixedly connected between the two connecting sleeves, and the handle is arranged in a shape of .

The beneficial effects of the utility model are as follows:

the method has the advantages that the soil is collected by adopting a mode of rotating and collecting the rotating roller, people only need to push the rotating roller to rotate through the handle, the aim of collecting a plurality of soil samples in saline-alkali soil is fulfilled, and compared with the traditional mode of sampling one by one, the method is quicker and more convenient, and is very suitable for places with large soil component differences, such as saline-alkali soil, and the practicability is high;

through setting up the sampling structure, run through a screw rod with recess in the bottom of sampling tube, consequently screw rod itself can't rotate, so sampling tube accessible screw rod is connected with the fixing base, and the screw rod can promote the inside removal of piston at the sampling tube, and then can conveniently release the soil of gathering, be convenient for release the soil, reached the effect of taking out the soil fast, it is convenient to use.

Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-4, a saline-alkali soil sampler comprises a rotary roller 1, shaft rods 2 are respectively arranged at two ends of the rotary roller 1, connecting sleeves 3 are respectively connected to the outer parts of the two shaft rods 2, which are close to one end, in a rotating manner, a plurality of sampling structures 5 are arranged on the outer parts of the rotary roller 1, each sampling structure 5 comprises a fixing seat 6 and a sampling tube 7, and each sampling tube 7 is arranged at the end of the fixing seat 6.

In this embodiment, the bottom of the sampling tube 7 is penetrated by a screw rod 8, a screw hole 9 is provided at the center of the upper surface of the fixing seat 6, and the screw rod 8 is in threaded fit with the screw hole 9.

The screw rod 8 can be fixedly connected with the sampling tube 7 and the fixed seat 6.
