Problems solved by technology

[0002] With people's increasing awareness of environmental protection, soil remediation is the top priority of the current environmental protection task. In the early stage of soil remediation, environmental protection evaluation units need to evaluate the pollution degree of the soil to be remediated, and then the remediation work cannot be avoided. For the sampling work in the early stage, most of the current samplers can only sample the surface or shallow layers for this type of sampling structure, but for the sampling of deep layers or specified depths, of course, the extraction of soil samples still faces the problem of efficiency, some small The device is also conceived, but it is always impossible to obtain a soil sample while ensuring a high excavation rate when taking soil, and then the work efficiency is low and cannot meet the current needs. In summary, there are many problems in the current soil taking device. Defects

Abstract

The invention discloses a soil sampling device. The soil sampling device comprises a sampling barrel, a transmission chamber, telescopic rods, a sampling pipe, and a material blocking mechanism; the transmission chamber is fixedly arranged on the upper end of an annular fixing block; the lower end of the annular fixing block is provided with four groups of telescopic rods; the movable ends of thetelescopic rods are connected with the annular fixing block through hinge joint; the fixed ends of the telescopic rods are connected with a fixing plate through hinge joint; the sampling pipe is connected with the internal side of the sampling barrel through slide connection; a sampling chamber is arranged on the internal side of the sampling pipe; the material blocking mechanism is arranged in the sampling chamber, and comprises a sleeve barrel, a threaded rod, a fan-shaped blocking plate, a connecting rod, and a rotating joint. The soil sampling device is novel in design; the four groups oftelescopic rods can be used for realizing mobile positioning of the transmission chamber, and realizing vertical sampling; sampling accuracy is increased; adopted tapered projections are contacted with the ground, so that the friction between the soil sampling device and the ground is increased, and stability is improved; the material blocking mechanism is adopted, so that soil excavated rate is increased greatly.
