Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of soil gas collection, in particular to an automatic soil gas collection device. Background Technique
[0002] Soil gas refers to various gas mixtures existing in the soil. They mainly come from the atmosphere, but some are also produced by biochemical processes in the soil. Soil air is an important part of the soil and is of great significance to plant growth and soil formation. Soil gas collection is an important means to obtain soil environmental information in fields such as environmental monitoring, geological exploration, and construction engineering. Soil gas collection usually uses a soil gas sampler, which generally consists of a special drill bit and a sampling tube. There is one or more openings on the sampling tube. The sampler collects gas samples in the soil by inserting the drill bit into the soil and pushing it to a certain depth.
[0003] However, when the existing sampler is in use, since the drill bit is inserted into the soil manually, when the collection depth is relatively deep, it will consume a lot of physical strength of the staff. And when collecting gas, some soil may be inhaled, which will cause pollution to the inside of the sampler. Content of the Utility Model
[0004] The purpose of the utility model is to provide an automatic soil gas collection device to solve the problems put forward in the above background technique.
