Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0021] The specific implementation of the present invention will be described in detail below in conjunction with specific embodiments.
[0022] Such as Figure 1~3 Shown is a structural diagram of a soil sampling device for environmental monitoring provided by an embodiment of the present invention, including a flow diversion mechanism and a sampling mechanism, and the flow separation mechanism is driven up or down by a power cylinder 8 for being driven by the power cylinder When descending, it opens outwards to squeeze and shunt the stones; the sampling mechanism includes a sampling cylinder 4 a...

The invention is applicable to the technical field of soil sampling, and provides a soil sampling device for environmental monitoring. The device comprises a shunt mechanism driven by a power cylinderto move up or down and used for expanding outwards to extrude and shunt stones when driven by the power cylinder to move down; and a sampling mechanism, the sampling device comprises a sampling barrel and a driving mechanism for driving the sampling barrel to move upwards or downwards, the sampling barrel comprises a plurality of arc-shaped sheets and splicing and inserting sheets; the pluralityof arc-shaped sheets are encircled into a cylindrical barrel structure through splicing and inserting sheets; the arc-shaped parts and the splicing and inserting parts are connected in an occlusion manner through the convex parts and the concave parts; the soil sampler disclosed by the invention has the beneficial effects that during sampling, the flow dividing block and the inserting pile can firstly move downwards to break soil, and then the flow dividing block is opened outwards, so that stones, broken bricks and the like are extruded outwards, then the sampling cylinder is used for sampling, and a complete soil sample can be obtained.
Description
technical field [0001] The invention relates to equipment related to environmental monitoring, in particular to a soil sampling device for environmental monitoring. Background technique [0002] With the development of the current society, the discharge of various sewage and wastes will not only cause water pollution and air pollution, but also when the soil contains too many harmful substances, exceeding the self-purification ability of the soil, it will cause the composition, structure and function of the soil Changes occur, microbial activities are inhibited, and harmful substances or their decomposition products gradually accumulate in the soil, which will cause soil pollution and endanger our safety. In order to detect the degree of soil contamination, soil sampling is required. [0003] In actual sampling, if there are stones, broken bricks, etc. on the surface of the sampling soil, it will be difficult for the sampling cylinder to drill into the soil, and forced dril...
