Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for high-standard farmland construction. Background Art

[0002] High-standard farmland construction refers to the comprehensive transformation and improvement of land through modern agricultural technology and management methods to ensure the stability and efficiency of agricultural production. In such farmland construction, the role of soil sampling devices is crucial because it can provide decision support for farmland management and ensure that soil quality meets the construction requirements of high-standard farmland.

[0003] According to the Chinese patent authorization announcement: CN217638090U, a high-standard farmland construction soil sampling device is disclosed, which includes a sampling tube and a support rod screwed on the top of the sampling tube, two symmetrically distributed handles are fixedly installed on the top of the support rod, and a cone head that can fit the inner wall of the sampling tube and move up and down is installed inside the sampling tube. The top of the cone head is fixedly connected with a core rod, and a nut sleeve is fixedly installed on the inner side of the top of the support rod; by arranging a cone head that can move up and down inside the sampling tube, the cone head is located at the bottom and moves downward without soil entering the sampling tube. After reaching the specified depth, the cone head is moved downward. Lift the head upward and continue to push the sampling tube downward to achieve the effect of sampling the soil at a specific depth. It is relatively simple for this device to probe into the soil layer and can take samples in a targeted manner to avoid contamination of the sampled soil. However, the soil sampling device still has shortcomings. After some soil sampling devices sample the soil, some soil still remains on the inner wall of the sampling tube. It is inconvenient to clean the inner wall of the sampling tube. The sampling tube is usually made of steel and is easily corroded by long-term contact with the soil. When the sampling tube is corroded, rust will release metal ions, which may contaminate the soil sample. The next time the soil is sampled, the accuracy of the sampling result may be affected.

[0017] 2. In the utility model, through the auxiliary sampling mechanism, when the user takes samples, he needs to take out the sample in the sampling tube, and put the two ends of the sampling tube on the fixed plate one and the fixed plate two respectively. The user starts the motor, and the motor drives the screw rod to slide the movable support. As the movable support slides, the connecting bent rod can drive the extrusion plate to move at the bottom of the limiting horizontal plate. The extrusion plate squeezes the conical push plate in turn, and the squeezed conical push plate drives the knocking arc plate to knock the bottom end of the sampling tube, thereby loosening the soil inside it, making it convenient for the user to take out a complete soil sample.
