Description

Technical Field

[0001] The present application relates to the field of land sampling, and in particular to a land sampling device for agricultural planning and design. Background Art

[0002] Agricultural planning and design refers to the systematic planning of agricultural land, resources, and facilities to improve production efficiency, sustainability, and economic benefits. This includes the design and arrangement of land use, crop selection, water resource management, soil improvement, facility layout, and ecological protection. Land sampling is a key step in agricultural planning and design, used to assess soil quality and characteristics to support scientific decision-making.

[0003] When taking land samples, a shovel is generally used to dig out the soil at the sampling location. However, when the shovel is digging the soil, the soil dug out is relatively loose, which makes it difficult to control the shape and size of the dug soil. The dug soil samples may be of different sizes and loose, which makes the sampled soil inconvenient to preserve and inspect, and has a certain impact on the subsequent processing operations of the sampled soil.

[0004] In view of the above-mentioned related technologies, the inventor believes that the sampled soil dug out by the shovel has the defects of varying sizes and being relatively soft. Therefore, a land sampling device for agricultural planning and design is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the limiting mechanism includes a threaded hole, which is opened in the middle of one end of a single shovel plate at the middle position, and mounting holes are opened through the middle of both sides of the shovel frame. A limiting clamp is movably installed inside the mounting hole, and one end of the limiting clamp abuts against the outer surfaces of multiple shovel plates. The upper surface of the limiting clamp extends to the inside of the threaded hole and is threadedly connected to a limiting bolt.

[0009] Preferably, a fastening bolt is installed at the opening of the outer surface of the limiting sleeve, and a fastening nut is threadedly connected to the outer surface of the fastening bolt, and one end of the fastening nut abuts against the outer surface of the limiting sleeve.

[0010] Preferably, the plurality of scraping plates are all located inside the limiting sleeve, the outer surfaces of the scraping plates abut against the inner wall of the limiting sleeve, and the scraping plates and the limiting sleeve are coupled to each other.
