[0021] Working principle: When the automatic lifting device for grain sampling in a container is needed, the first motor 3 starts, driving the first rotating wheel 4 to rotate.

The second rotating wheel 6 is connected to the threaded rod 8, thus driving the threaded rod 8 to rotate. Furthermore, the rotation of the threaded rod 8 drives the lifting plate 9 to rise and fall.

In terms of work efficiency, when the sampling needle 20 needs to be rotated to adjust its angle, the servo motor 11 is started, which drives the first gear 12 to rotate. Subsequently, the rotation of the first gear 12 drives the second gear 13 to rotate. After that, the hydraulic cylinder 14 is started, which drives the push plate 15 to slide.
