Soil sampling and detecting equipment

Abstract

The invention relates to soil sampling and detecting equipment, which comprises a sampling cylinder, wherein a soil sampling arc groove is arranged inside the sampling cylinder, and is movably fixed on the sampling cylinder through a rotation shaft, the rotation shaft is controlled by a rotation shaft rod, the bottom portion end of the soil sampling arc groove is provided with an arc notch, the arc notch is just corresponding to the horizontal plane on the bottom portion, and one sampling cylinder side away from the rotation shaft end is provided with a material outlet. Compared to the soil sampling and detecting equipment in the prior art, the soil sampling and detecting equipment of the present invention has the following advantages that the whole machine structure is simple, the volume is small, the transportation is convenient, the sampling process is convenient, the whole sampling process is mechanically controlled without additional assistance by hands, the time is saved, and the manpower resources are saved.

Description

technical field [0001] The invention relates to soil quality sampling and testing equipment, which belongs to the technical field of sampling and testing equipment. Background technique [0002] Soil quality sampling and detection is one of the important basic tasks for scientific and technological workers engaged in environmental and ecological research. Accurate and appropriate collection of soil or sediment at different depths is directly related to the accuracy of related research and the reliability of data. The soil quality sampling detection structure in the prior art is complicated, and it is inconvenient to carry after sampling, and auxiliary sampling needs to be performed by hand during the sampling process, which wastes time and human resources. [0003] The device is mainly aimed at mineral soils with low organic matter content, and it is difficult to cut the solid organic matter layer or plant root system of organic soils. Although some samplers with small diame...

The soil sampling and detection structure in the prior art is complicated, it is inconvenient to carry after sampling, and auxiliary sampling needs to be performed by hand during the sampling process, which wastes time and human resources

[0003] The device is mainly aimed at mineral soils with low organic matter content, and it is difficult to cut the solid organic matter layer or plant root system of organic soils. Although some samplers with small diameters can barely be inserted into the soil, the sampling volume is small, and the characteristics of the soil profile are difficult to distinguish. Due to the large contact area of ​​the larger sampler with the soil surface, the insertion resistance also increases, and the compression of the soil during sampling is inevitable. Even if the soil is inserted, the gravity of the soil sample is much greater than the friction of the pipe wall. It is difficult to take out the soil sample completely, therefore, it is difficult for the existing soil sampling device to obtain the undisturbed soil, and the sampling error is significant
