Contaminated soil sampling equipment

Abstract

The invention discloses contaminated soil sampling equipment, and relates to the technical field of soil sampling devices. The equipment comprises a base, a mounting frame, an L-shaped block, a compression spring, a fixed rod, a screw rod, a first servo motor, a moving block, a sampling pipe, a connecting rod, a first gear, a second servo motor, a second gear, a first mounting block, an impeller,a second mounting block, an annular pipe, a first cavity, a first annular rack, a first rotating shaft, a third gear, a crawler belt, a second cavity, a second annular rack, a second rotating shaft, afourth gear, a crushing knife, a reset spring, a fixed block, a contact, a filter screen, a first magnet, a first electromagnet, a second magnet, a second electromagnet, a switch, a movable rod and asliding block. Movement of the sampling pipe is stopped when the crushing knife makes contact with a hard object, collision between the sampling pipe and the hard object is avoided, the working effect of the device is guaranteed, the supporting effect of the device is improved in the sampling work process, and the stability of the sampling pipe in the movement process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of soil sampling devices, in particular to a contaminated soil sampling device. Background technique [0002] 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 soil, which will endanger human health. The extent is soil pollution. In the process of soil pollution improvement, soil sampling must be carried out first, followed by pollution source analysis. Firstly, it is necessary to understand the soil quality deep in the soil in order to carry out comprehensive restoration of the soil. Soil sampling equipment is usually used to sample contaminated soil. [0003] Existing polluted soil sampling equipment usually needs to take the sampling tube deep into...

Problems solved by technology

[0003] The existing polluted soil sampling equipment usually needs to take the sampling tube deep into the ground for sampling. When there are hard objects such as stones buried underground, the sampling tube will easily be damaged when it collides with it, which will affect the working effect of the device.
