An agricultural soil pollution degree detection device

Abstract

The invention discloses an agricultural soil pollution degree detection device, which relates to the technical field of soil detection. The agricultural soil pollution degree detection device includes a cylinder body, the bottom of the cylinder body is equidistant and circumferentially hinged with three support legs, and the top of the cylinder body is movable with a storage handle, and the left and right sides of the cylinder body are respectively fixed and installed. There are soil liquid phase detectors and soil gas phase detectors, and there are opening and closing plates under the soil liquid phase detectors and soil gas phase detectors. The two opening and closing plates are respectively hinged on the left and right sides of the cylinder and penetrate the inner wall of the cylinder. . The agricultural soil pollution degree detection device, through the setting of the sampling mechanism, can complete the sampling work of different depths of soil in the process of inserting and pulling out the soil layer in a single time, and can effectively avoid the intermixing of soil at different depths from affecting the detection accuracy However, the sampling mechanism can effectively crush and store solidified soil clods during the sampling process.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to an agricultural soil pollution degree detection device. Background technique [0002] my country is a big country in the production and use of pesticides. The long-term excessive and simple application of chemical fertilizers has deteriorated the physical properties of the soil, polluted the land and changed its original use. Excessive accumulation of nitrate and phosphate in the soil will flow into rivers, lakes and other waters with water, which will cause eutrophication of water body. As a result, it has a serious impact on the ecological environment, and even threatens the normal life and health of residents. Soil detection methods generally include gas chromatography, ASF soil detection method, high performance liquid chromatography and X-ray fluorescence spectrometry. The above methods all need to be tested by soil sampling. In order to solve the disadvantages of lo...

Problems solved by technology

However, the degree of soil pollution is different at different depths underground. Therefore, when sampling soil at different depths, it is necessary to insert and pull out the sampling device multiple times to complete the sampling of soil at different depths. During the process, the contact part between the sampling device and the soil needs to be cleaned after each sampling, so as to avoid the situation that the soil at different depths is mixed with each other and affect the accuracy of the test. Although this sampling method is more efficient than laboratory testing , but there are still defects that affect the detection accuracy and efficiency
