Deep independent soil monitoring and sampling device

Abstract

The invention discloses a deep independent soil monitoring and sampling device. The device comprises a lifting cylinder, a power cavity is formed in the upper portion of the lifting cylinder and is in through connection with an inner cavity of the lifting cylinder through a through hole, and the top wall of the inner cavity of the power cavity is fixedly connected with a hydraulic cylinder. The bottom end of a telescopic rod on the hydraulic cylinder penetrates through the through hole and is rotationally connected with a sampling barrel matched with the lifting barrel through a bearing seat; the bottom end of the sampling barrel is fixedly connected with a soil breaking cone matched with the lifting barrel; one side end of the sampling barrel is connected with the sampling hole in a penetrating manner, and the outer side of the sampling barrel is sleeved with a pushing sleeve matched with the lifting barrel; the pushing sleeve is in threaded connection with the lifting cylinder, a rotating disc is arranged above the lifting cylinder and fixedly connected with the lifting cylinder through a plurality of connecting rods, and a plurality of handles are evenly arranged on the outer circle face of the rotating disc. The whole sampling work is very simple, wherein the deep soil can be directly and independently sampled, so that the quality of a soil sample can be ensured, and the accuracy of later detection and analysis is ensured.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a deep independent soil monitoring and sampling device. Background technique [0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by urban sewage, sludge, and manure. When there are too many harmful substances in the soil and exceed the self-purification capacity of the soil, the composition, structure and function of the soil will change, the microbial activities will be inhibited, and the harmful substances or their decomposition products will gradually accumulate in the s...

Problems solved by technology

We will use soil sampling devices to understand some soil pollution situations, but we will encounter some problems when using sampling devices. For example, some sampling devices can only sample shallow soil when using them. For deeper or profile Layered soil sampling is time-consuming and laborious. At the same point, the shallow layer must be sampled first, and then the deep soil sampled. It is difficult to sample the deep soil separately. The sampling work is very troublesome, and it is easy to confuse the shallow sample soil with the deep layer. sample soil
