The invention discloses a sampling device for soil leaching liquid, comprising a box body, wherein a first cavity and a second cavity are opened inside the box body, a lift plate is arranged inside the first cavity, and a container is arranged on the upper end of the lift plate A filter cup is slidably connected to the inside of the container cup, a side door is rotatably connected to the side wall of the filter cup, an inner shaft is rotatably connected to the inside of the filter cup, an outer shaft is sleeved on the outer side wall of the inner shaft, and the inner shaft is connected to the outer shaft. There are a plurality of stirring rods on the outer side wall of the filter cup, and filter screens are arranged inside the filter cup and located at the lower ends of the inner shaft and the outer shaft. The invention can make the stirring rod quickly rotate through the reverse rotation of the inner shaft and the outer shaft. Stir the soil and deionized water evenly, and through the reverse rotation of the stirring rod, the flow of the deionized water is made more rapid, so that the elements inside the soil are quickly separated from the soil particles under the impact of the water flow and then dissolved into the deionized water. water, so that the extraction of the soil leaching solution is more sufficient. |
