However, due to the solid and hard soil of dry land such as fruit forests and economic forests, traditional soil samplers are very laborious when sampling deep layers of such soils. There are disadvantages that it is difficult to take out after entering. It is also difficult to pour out the soil samples from the sampling tube, and even some soil samples will still adhere to the inner wall of the sampling tube, affecting the detection accuracy. Therefore, it is urgent to provide a new type of soil sampler to solve the above problems. Utility Model Content
