The discharge push rod 4 passes through the handle 2 and is fixedly connected to the discharge plate 3. Soil sampling handles 21 are fixedly installed on both sides of the upper end of the handle 2. Discharge handles 41 are fixedly connected to both sides of the upper end of the discharge push rod 4. Sliding grooves are opened on both sides of the handle 2. The discharge handles 41 are slidably set in the sliding grooves. A fixing part 5 is installed on the upper end of the discharge push rod 4. The fixing part 5 is detachably connected to the handle 2.
[0030] Specifically, a discharge plate 3 is installed inside the soil sampling cylinder 1, and the discharge plate 3 is fixedly connected to the discharge push rod 4. The discharge push rod 4 is slidably installed inside the handle 2. When sampling soil, the soil sampling cylinder 1 is pressed down by holding the soil sampling handle 21 to insert the soil sampling cylinder 1 into the soil to a suitable depth. After the soil sampling is completed, the soil sampling cylinder 1 is placed on the container holding the soil. By pushing the discharge handle 41, the discharge plate 3 slides and pushes the soil in the soil sampling cylinder 1 into the container.
[0031] In this way, by setting up the unloading plate 3 and the unloading push rod 4, it is convenient to pour out the soil after the soil is taken from the soil sampling cylinder 1. At the same time, the unloading through the unloading plate 3 reduces the amount of soil residue in the soil sampling cylinder 1, and reduces the possibility of mixing with other soils during the next soil sampling, which may interfere with the judgment of the soil condition.
[0032] In some feasible configurations, the soil sampling cylinder 1 is cylindrical, the handle 2 and the unloading push rod 4 are tubular, and the unloading disc 3 is disc-shaped. A silicone ring is provided between the outer side of the unloading disc 3 and the inner side of the soil sampling cylinder 1 to facilitate cleaning.
