Problems solved by technology

[0009] This patent samples by arranging a plurality of adjacent sampling inner cylinder sections. In fact, when it is necessary to sample soil at different heights at a certain place, since the single inner cylinder section at the bottom needs to sequentially penetrate through the For the soil to be sampled above, this process is extremely easy to cause cross-contamination of samples collected at various depths, and the representativeness is poor, which makes the error of the test results too large and cannot accurately reflect the actual situation of the research soil layer

Embodiment 1

[0048] Embodiment 1 discloses a power part 2 of an intelligent soil stratified sampling device, which at least includes: a sampling pipe body 1 and a power part 2 arranged on the sampling pipe body 1 .

[0049] According to a preferred embodiment, as figure 1 As shown, the sampling pipe body 1 is provided with a collection pipe 3, and the collection pipe 3 is uniformly provided with at least one collection bin 4 along the axial direction. Closing device 6, when the sampling pipe body 1 moves into the soil under the action of the power part 2, the central processing device 7 can generate a signal for controlling the opening and / or closing of the opening and closing device 6 according to the collected soil parameters of the sensor 5. Acquire the Signal.

[0050] Preferably, the central processing device 7 may be electrically connected to the switching device 6 and the sensor 5 through built-in wires. Preferably, the central processing unit 7 and the wireless communication modu...

Embodiment 2

[0070] This embodiment discloses an intelligent layered soil sampling method. In the case of no conflict or contradiction, the whole and / or part of the content of the preferred implementations of other embodiments can be used as a supplement to this embodiment.

[0071] According to a preferred embodiment, the method at least includes a sampling tube body 1 and a power part 2 arranged on the sampling tube body 1, a collecting tube 3 is arranged in the sampling tube body 1, and at least one collecting tube 3 is uniformly arranged in the axial direction. The bin 4 and the sampling pipe body 1 are provided with at least one sensor 5 and an opening and closing device 6 corresponding to the collection bin 4 .

[0072] According to a preferred embodiment, soil layered sampling method comprises at least:

[0073] S1: Obtain and collect soil parameters through the sensor 5 and transmit them to the central processing device 7,

[0074] S2: when the collected soil parameters are within...

Embodiment 3

[0092] Such as figure 2 As shown, the intelligent layered soil sampling device at least includes a sampling pipe body 1 . The sampling device comprises at least a cutting head 10 . The sampling device comprises at least one collection bin 4 . Preferably, a plurality of collection bins 4 are arranged adjacently in sequence along the length direction of the sampling device. The cutting head 10 forms a soil channel allowing the sampling pipe body 1 to pass through during the non-sampling period. The way the cutting head 10 forms the soil channel can be manual or electric. The sampling device is configured to form a soil channel through the cutting head 10 to allow the sampling pipe body 1 to pass through during non-sampling period, so as to place the collection bin 4 at a designated position in the soil channel. The cutting head 10 is driven by an external force to drill down into the soil until the collection bin 4 is placed at a designated position in the soil channel. Th...

Abstract

The invention relates to intelligent soil stratified sampling equipment, comprising a sampling pipe body and a power unit arranged on the sampling pipe body, a collecting pipe is arranged in the sampling pipe body, the collecting pipe is uniformly provided with at least one collecting bin in the axial direction, the sampling pipe body is provided with at least one sensor corresponding to the collecting bin as well as an opening and closing device, under the condition that the sampling pipe body moves into soil under the action of the power unit, a central processing unit can generate an acquisition signal, used for controlling the opening and closing device to be opened and / or closed, according to soil parameters acquired by the sensor. The intelligent soil stratified sampling equipment provided by the invention has the advantage that a sensor and an opening and closing device are correspondingly arranged on each collecting bin in the collecting pipe, parameters, used for physical analysis, of target soil can be accurately and effectively acquired by virtue of the sensor, the effect that each collecting bin can accurately collect target soil in a preset soil parameter interval is guaranteed, and the effect that parameters, used for the physical analysis, of soil in each collecting bin are different or can not be partially coincided is guaranteed.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to an intelligent soil layered sampling device and method. Background technique [0002] Soil environment monitoring refers to the determination of environmental quality (or pollution degree) and its changing trend through the determination of representative values ​​of factors affecting soil environmental quality. The so-called soil monitoring refers to soil environmental monitoring, which generally includes technical content such as point sampling, sample preparation, analysis method, result characterization, data statistics and quality evaluation. Among them, the rocks on the earth's surface undergo weathering and gradually break down into loose mineral particles of various sizes (called parent materials). Soil is formed and evolved under the comprehensive action of various soil-forming factors such as parent material, climate, organisms, topography, and time. The compos...
