The upper end of the sampling cylinder 1 is also equipped with a pushing assembly. The push plate 12 is slidably installed inside the sampling cylinder 1, and the movement of the push plate 12 is controlled by the elastically set frame plate 13. The spring 16 pushes the sleeve plate 14 to move upward so that the push plate 12 is at the upper end of the inner cavity of the sampling cylinder 1 under normal conditions, so as to avoid affecting the soil collection of the sampling cylinder 1. After the sampling cylinder 1 is taken out, the personnel can push the push handle 15 to control the frame plate 13 to descend, and the push plate 12 to squeeze out the soil, so as to realize the rapid discharge of the soil and improve the work efficiency.
