[0002] Soil sampling is an important step in soil analysis and evaluation in many fields such as agriculture, environmental science, geology, etc. Traditional soil samplers usually use simple digging or drilling methods, but their use effect is not ideal under certain terrain conditions, such as slopes. Due to the inclined and unstable characteristics of slope terrain, traditional samplers often encounter problems such as soil slippage, incomplete sampling, or damage to the slope during the soil sampling process.

[0003] In addition, traditional samplers often require greater force or special operating skills when taking samples, which not only increases the difficulty of operation, but may also cause physical harm to the sampler. In order to solve the above problems, we propose a soil sampler for soil testing that solves the problem of difficult soil collection on slopes, aiming to overcome the shortcomings of traditional samplers and provide a more convenient, efficient and accurate solution for soil sampling.
