Layered sampling device and method for contaminated soil in temporary storage warehouse

Abstract

The invention relates to the technical field of soil sampling, and discloses a layered sampling device and method for contaminated soil in a temporary storage warehouse. The device comprises a mounting plate, and a support is fixedly connected to the upper surface of the mounting plate; a driving motor is fixedly connected to the inner side of the support, a rotating shaft is fixedly connected tothe output end of the driving motor, and a driving gear is fixedly connected to the bottom end of the rotating shaft. According to the invention, the layered sampling device is provided with the driving motor, so when the contaminated soil needs to be sampled, an external power supply starts the driving motor to drive the rotating shaft to rotate, the rotating shaft rotates to drive the driving gear to rotate, the driving gear drives the driven gear to rotate so as to drive the drill rod to rotate, the drill rod rotates to drive the drill bit to rotate, the drill rod and the drill bit rotate,and under the matching action of a spiral part, the device is held by a hand to drill holes into soil, so soil feeding is more convenient, and the soil is simpler and more convenient to use in the subsequent collection process.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a layered sampling device and method for polluted soil in a temporary storehouse. Background technique [0002] With the rapid development of social economy and the acceleration of urbanization, environmental pollution is becoming more and more serious, which seriously damages the ecosystem. The pollution of soil and water sources has a huge impact. Therefore, soil testing projects need to sample and detect polluted soil in real time. [0003] Soil sampling devices generally obtain soil samples by inserting sampling tubes deep into the soil, but the existing soil sampling devices are inconvenient to enter the soil and take samples. Sampling, at present, only soil samples at the same depth can be collected at a single time, and multiple sampling is required, which is inefficient, increases workload and wastes time.
