Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a fixed-depth excavator for outdoor soil detection and sampling. Background Art

[0002] Soil testing is the process of conducting a series of experiments and analyses on soil samples to determine the physical properties, chemical composition and biological characteristics of the soil. This includes testing of soil texture and structure, pH value, nutrient content, organic matter content, and the content of heavy metals and harmful substances. Comprehensive soil testing can provide important references for agricultural production, horticultural management and environmental protection, help formulate appropriate soil management and remediation strategies, improve soil quality, protect the environment, and increase crop yields and quality.

[0003] Currently, soil is usually dug up with a shovel and a portion of the soil is selected as a sample. Although this method is simple, soil from multiple depths may be mixed together during the shoveling process, resulting in contaminated or unrepresentative samples. This may affect the accuracy of sampling a specific soil layer, especially when the soil characteristics at a specific depth need to be studied. Utility Model Content

This ensures that the sampling head will not deviate or move during the sampling process, thereby avoiding the mixing of soils at different depths.

[0015] One-time deep sampling: Since the excavator can accurately control the depth of the sampling head, users can collect soil samples at a specific depth in one operation. This fixed-depth sampling method not only saves time and labor, but also ensures the consistency and comparability of sampling.

[0016] Reliable data results: By ensuring that the sampling depth and location are accurate, the technical solution provides high-quality soil samples.
