Description

Technical Field

[0001] This utility model relates to soil samplers, and in particular to portable soil samplers for crop cultivation, belonging to the field of crop cultivation technology. Background Technology

[0002] Soil sampling is crucial in agriculture, primarily for assessing soil nutrient status, physical properties, and health. Analyzing soil samples reveals the content of nutrients such as nitrogen, phosphorus, and potassium, as well as indicators like pH and organic matter content. This information helps farmers develop scientific fertilization plans, avoiding over- or under-fertilization, improving fertilizer utilization, and reducing environmental pollution. Furthermore, soil sampling can detect harmful substances such as heavy metals and pesticide residues, assess soil health, prevent crop diseases, and ensure the safety and quality of agricultural products. Long-term soil monitoring data can also guide crop rotation systems and soil improvement measures, promoting sustainable agricultural development.

[0003] In the prior art, such as the utility model with application number 202321002275.X, a soil sampler is disclosed. In order to solve the problems of traditional shovel heads being of a one-piece structure, which are time-consuming and laborious to remove soil, and the easy retention of soil on the inner wall of the shovel head, making it inconvenient to clean and affecting the convenience of the sampler, a split sampling structure is designed. The shovel head consists of a fixed shovel and a split shovel. When in use, the fixed shovel and the split shovel are assembled and used. When removing soil samples, the fixed shovel and the split shovel can be separated. This facilitates soil sample collection and cleaning, avoids soil residue, and prevents it from affecting the next sampling, thereby improving the collection of sample images for use.

[0004] The above-mentioned applications still have shortcomings:

[0005] Although the shovel head adopts a detachable design, it is inconvenient to install and remove the shovel head, and it is not convenient to apply downward pressure when inserting it. In addition, after the shovel head is separated, the soil sample has a certain moisture and will stick to the inner wall of the fixed shovel, making it impossible to quickly loosen and remove the sample.

[0006] To address these issues, a portable soil sampler for crop cultivation was designed. Utility Model Content

[0007] The main purpose of this invention is to provide a portable soil sampler for crop cultivation to solve the problems mentioned in the background art.
