The first driving means 30 is provided on the apparatus body 10, and the first driving means 30 can drive the detection plunger 21 to be inserted into the soil.
The detection inserted bar 21 is driven by the first driving device 30 to be inserted into soil, the soil enters the sample conveying cavity inside the detection inserted bar 21, and then soil samples obtained from different soil layers are conveyed to the sample collector 23 to be stored according to the depth change of the soil layers through the sample conveyor 22. The soil ecological environment monitoring equipment provided by the embodiment of the invention can be inserted into soil layers with different depths at one time, accurately detect the soil quality condition of each soil layer, collect and sample soil samples, and facilitate various subsequent detections.
The specific structure of the detection inserted rod 21 can adopt one of the following embodiments:
