Workers use a sampling rod to obtain samples, place them in a storage box, and then repeat the process. This sampling method not only consumes a lot of manpower and resources, but also may lead to grains carrying biological pests entering the country due to human negligence, thereby endangering my country's ecological security.

The first transmission plate 6, fixed by the transmission component, will drive the transmission component to rotate. When the transmission component rotates, it will drive the connecting column 10 to move. The connecting column 10, fixed by the sliding plate 11, will drive the sliding plate 11 to move. The sliding plate 11, fixed by the sampling rod 13, will drive the sampling rod 13 to move, thereby achieving the effect of automatic sampling of grain.

[0020] Reference Figure 1 , Figure 2 and Figure 5 The outer wall of the support frame 3 is provided with a lifting assembly. The inner wall of the lifting assembly is threadedly connected to a threaded rod 20. The inner wall of the lifting assembly is slidably connected to a support column 16.

[0022] Working principle: The first motor 1 is started to drive the turntable 2 to rotate, which in turn drives the first fixed column 4 and the second fixed column 5 to rotate. When the first fixed column 4 contacts the transmission block 12, it will drive the transmission block 12 to move, which in turn drives the sliding plate 11 to move. When the sliding plate 11 moves, it will drive the connecting column 10 to move. When the connecting column 10 moves, it will slide through the sliding groove 9 on the inner wall of the second transmission plate 8, which will further drive the second transmission plate 8 to rotate. When the second transmission plate 8 rotates, it will drive the first transmission plate 6 to rotate. When the first fixed column 4 disengages from the transmission block 12, the second fixed column 5 will contact the first transmission plate 6 and drive the first transmission plate 6 to rotate on the outer wall of the third fixed column 7, which will then drive the second transmission plate 8 to rotate. At this time, the second transmission plate 8 will drive the sliding plate 11 to move in the opposite direction. Through the rotation of the first fixed column 4 and the second fixed column 5, the extension and retraction of the sampling rod 13 can be automatically adjusted to achieve the effect of automatically collecting grain samples.

[0023] The second motor 19 is started to drive the threaded rod 20 to rotate. When the threaded rod 20 rotates, it drives the threaded block 14 to move up and down, which in turn drives the collar 15 to move up and down on the outer wall of the support column 16. Since the threaded block 14 is fixedly connected to the support frame 3, the up and down movement of the threaded block 14 will drive the support frame 3 to move up and down, thereby achieving the effect of adjusting the height of the sampling rod 13, enabling it to collect grain samples at different heights, and providing a more comprehensive and accurate sample basis for grain quality testing and other work.
