Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to a forestry ecological soil sampler. Background Art

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of forests to play a protective role. It is one of the important components of the national economy. Forestry is engaged in the cultivation, protection and utilization of forest resources between humans and the biosphere through advanced science and technology and management methods, fully utilizing the multiple benefits of forests, and can sustainably manage forest resources to promote the coordinated development of population, economy, society, environment and resources. It is a basic industry and social welfare undertaking.

[0003] The balance of forestry ecological system is of vital importance, so it is necessary to regularly test forestry ecology. Soil testing is a crucial part of forestry ecological testing, and portable soil samplers are commonly used tools for soil sampling. However, when using the original forestry ecological soil sampler, it is difficult to reliably change the soil sampling depth according to the actual testing needs, which affects the test results.

[0004] Those skilled in the art have conducted research and improvements on this, such as a forestry ecological soil sampler with application number CN202121247113.3. This technical solution inserts the sampling head directly into the ground for soil sampling. After the sampling is completed, the device is pulled out and the soil sample is pushed out of the sampling head through the bulldozer assembly. However, the sampling capacity of this technical solution is limited and the sampling depth is difficult to control. For this reason, we propose a forestry ecological soil sampler.
