[0002] At present, the soil quality will deteriorate after Astragalus is planted, and quality monitoring is needed. During monitoring, it is necessary to use a soil sampling device to sample the soil, and then analyze and study the sampling.

[0003] The existing sampling device still has the following deficiencies when used:

[0004] One is that although the existing device is provided with a pushing structure, the soil in the sampling tube can be pushed out by the pushing structure, but when the pushing structure is damaged, it is inconvenient to take out the soil in the sampling tube; the existing structure for pushing the soil in the sampling tube mostly adopts a threaded drive, and the entire pushing process wastes time. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sampling device for detecting the soil quality of an Astragalus membranaceus planting area, so as to solve one problem: although the existing device is provided with a pushing structure, the soil in the sampling tube can be pushed out by the pushing structure, but when the pushing structure is damaged, it is inconvenient to take out the soil in the sampling tube; the existing structure for pushing the soil in the sampling tube mostly adopts a threaded drive, and the entire pushing process wastes time.

[0006] The purpose and efficacy of the sampling device for detecting soil quality in an astragalus planting area of ​​the present invention are achieved by the following specific technical means:

[0007] A sampling device for detecting soil quality in an astragalus planting area includes a main body plate; a sampling tube is welded to the bottom of the main body plate, the sampling tube is a cylindrical tubular structure, and sampling holes are arranged in an array on the outer wall of the sampling tube, and the sampling holes are circular hole structures.

[0008] Furthermore, a cleaning assembly is installed in the main body plate, and the cleaning assembly consists of a seat body, a connecting block, a stop block, a limiting groove, a screw, a threaded rod and a cleaning block. A concave seat body is welded on the top surface of the main body plate, and a hexagonal connecting block is slid on the seat body. A limiting groove is provided on the front end surface of the connecting block, and a screw is threadedly connected to the seat body, and the rear end of the screw is inserted into the limiting groove.

[0009] Furthermore, a threaded rod is threadedly connected to the connecting block, and one lower end of the threaded rod is rotated on the cleaning block, which slides in the sampling tube, and the outer wall of the cleaning block contacts the inner wall of the sampling tube.

[0010] Furthermore, a stopper is welded on the bottom end face of the connecting block. The stopper is a rectangular plate-shaped structure. The top face of the stopper contacts the top face of the inner wall of the base body. When the top face of the stopper contacts the top face of the inner wall of the base body, the screw is aligned with the limiting groove on the cleaning block.

[0011] Furthermore, two handles are symmetrically welded on the top of the main body plate, and the two handles together constitute the driving part of the sampling cylinder.

[0012] Furthermore, an auxiliary groove is provided at the bottom of the sampling tube, and the auxiliary groove is a tapered groove structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present application, by setting up the sampling holes, on the one hand, since the sampling holes are arranged in an array, the soil at different positions can be sampled; on the other hand, after the sampling is completed, the soil needs to be discharged from the sampling tube. During the process of removing the soil, if the resistance is too large, a cylindrical rod can be inserted into the sampling hole to crush the soil in the sampling tube, and the soil can be conveniently taken out of the sampling tube.

[0015] In the present application, through the setting of the cleaning component, on the one hand, when cleaning the sample in the sampling barrel, it is sufficient to directly rotate the threaded rod. Under the drive of the threaded rod, the cleaning block moves downward, and at this time the soil in the sampling barrel can be pushed out of the sampling barrel through the cleaning block; on the other hand, when it is necessary to quickly remove the residue in the sampling barrel, it is sufficient to directly loosen the screw and then push the threaded rod downward. Compared with the existing device, the present device can be cleaned by two different methods, and the structure is flexible. BRIEF DESCRIPTION OF THE DRAWINGS

After the sampling is completed, hold the two handles 3 and pull it upwards. After the sampling tube 2 is pulled out of the soil, samples are taken from the sampling holes 201. Since the sampling holes 201 are arranged in an array, soil at different positions can be sampled. After the sampling is completed, the soil needs to be discharged from the sampling tube 2. During the process of removing the soil, if the resistance is too large, a cylindrical rod can be used to insert Go to the sampling hole 201 to crush the soil in the sampling tube 2, and then the soil can be easily taken out of the sampling tube 2; when cleaning the sample in the sampling tube 2, just rotate the threaded rod 406, and under the drive of the threaded rod 406, the cleaning block 407 moves downward. At this time, the soil in the sampling tube 2 can be pushed out of the sampling tube 2 through the cleaning block 407; when it is necessary to quickly remove the residue in the sampling tube 2, just loosen the screw 405 and then push the threaded rod 406 downward.
