When the screw 8 rotates, it can not only drive the rotating disk 18 to rotate synchronously through the telescopic transmission mechanism, but also drive the externally threaded tube I 12 and the externally threaded tube II 13 to rotate synchronously. Since the slide cylinder I 9, the slide cylinder II 10 and the slide cylinder III 11 all slide along the axial direction, and the screw 8 and the slide cylinder I 9, the slide cylinder III 11 are Cylinder II 10 is threadedly connected with external threaded tube I 12, and slide cylinder III 11 is threadedly connected with external threaded tube II 13, so when the screw rod 8 rotates, it will drive slide cylinder I 9, slide cylinder II 10, and slide cylinder III 11 to slide vertically, so that the sand taking cylinder 19 can continuously move downward while rotating. When the sand taking cylinder 19 rotates, the serrations at the bottom will crush the soil layer, so that the sand taking cylinder 19 can penetrate into the soil layer. Through the coordinated arrangement of the fixed cylinder 6, the screw rod 8, slide cylinder I 9, slide cylinder II 10, slide cylinder III 11, external threaded tube I 12, external threaded tube II 13 and the telescopic transmission mechanism, the long-distance transmission of the sand taking cylinder 19 can be realized, the sand and soil in deeper depths can be taken out, and the working distance of the sand taking device is improved.

[0026] Embodiment 2: Embodiment 2 is different from Embodiment 1 in that Figure 1 As shown, the support rod 2 and the fixing plate 3 are hingedly connected by a hinge. Through the hinged connection between the support rod 2 and the fixing plate 3, the bottom surface of the fixing plate 3 can be more closely fitted to the ground, so that the device can adapt to different terrains.
