Embodiment 1

[0031] like figure 1 as shown, figure 1 Schematic diagram of the structure of the collection device provided by the embodiment of the present invention.

[0032] An embodiment of the present invention provides a multi-layer collection device for cultivated land soil samples, including: a housing 1 and a drive motor 2 arranged above the housing 1, refer to figure 1 and figure 2 As shown, the inner middle part of the housing 1 is provided with a soil collection chamber 3, and the soil collection chamber 3 is equipped with a rotating rod 4 whose top end is in transmission connection with the drive motor 2 and whose bottom end extends out of the housing 1. The soil collection chamber 3. A helical blade 5 is installed on the rotating rod 4 below the top opening, and the rotating rod 4 rotates under the drive of the drive motor 2. The helical blade 5 provided on it can collect soil and transport the soil upward along the soil collection chamber 3.

[0033] In order to realize so...

Embodiment 2

[0037] In addition to the soil collection and layered storage provided by the above embodiments, the embodiment of the present invention also includes gas collection and layered storage corresponding to the soil. The specific scheme is as follows:

[0038] An air suction pump 10 is also arranged above the casing 1, and a gas collection chamber 11 is opened between the inside of the casing 1 and the outside of the soil collection chamber 3, and a top end and an air suction pump 10 are installed in the gas collection chamber 11. It is connected with the suction pipe 12 whose bottom end protrudes from the shell 1; under the action of the suction pump 10, the suction pipe 12 can collect gas from the head of the collection device and transport the gas upward along the suction pipe 12.

[0039]In order to realize gas storage, a plurality of gas collection boxes 13 arranged up and down are installed in the gas collection chamber 11, and the gas extraction pipes 12 are arranged through...

Embodiment 3

[0045] Different from the above-mentioned embodiments, the soil collection box 7 and the gas collection box 13 of this embodiment are all provided with a sampling port 16, which is convenient for taking out samples therefrom after the soil and gas sampling work is completed, such as the sampling of the soil collection box 7 The port 16 is an opening for taking out the soil on the side wall of the soil collection box 7 , and the sampling port 16 of the gas collection box 13 is an air outlet valve that runs through the gas collection box 13 .

[0046] Further, the housing 1 and the soil collection chamber 3 are cylindrical structures, and the soil collection chamber 6 and the gas collection chamber 11 are separated by partitions 21 between the inside of the housing 1 and the outside of the soil collection chamber 3. For example, the space between the inside of the shell 1 and the outside of the soil collection chamber 3 is equally divided by the partition plate 21, that is, the s...

Abstract

The invention relates to the technical field of land sampling, in particular to a farmland soil sample multi-layer collecting device and method.The device comprises a shell and a driving motor arranged above the shell, and a soil collecting cavity is formed in the middle of the inner side of the shell; a rotating rod of which the top end is in transmission connection with the driving motor and the bottom end extends out of the shell is mounted in the soil collecting cavity; a spiral blade is mounted on the rotating rod below the top opening of the soil collecting cavity; a soil collecting cavity is formed between the inner side of the shell and the outer side of the soil collecting cavity, a top opening of the soil collecting cavity is communicated with the top opening of the soil collecting cavity, a plurality of soil collecting boxes which are arranged up and down are installed in the soil collecting cavity, and the bottom ends of the soil collecting boxes are connected with a bottom plate through electric hinge mechanisms which are opened and closed downwards. According to the collecting device, the soil collecting box with the electric hinge mechanism is adopted, so that layered storage of soil at different depths is facilitated, mixing of soil at other depths is avoided, and the accuracy of a detection result can be ensured.

Description

technical field [0001] The invention relates to the technical field of land sampling, in particular to a multi-layer collection device and collection method for cultivated land soil samples. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, industrialization, and agriculturalization, the environmental problems associated with the rapid development of soil and economy have become increasingly prominent. Due to improper operation or management in the production process, more and more soils have suffered Heavy metal pollution, soil heavy metal pollution is concealed, lagging and long-term. Heavy metals enter plants through the root system, and the growth of plants is inhibited. Heavy metal pollution will also directly or indirectly endanger industrial and agricultural production and human health. Therefore, pollution Soil governance is imminent. [0003] In the measurement and research of soil, it is necessary ...
