The opening and closing assembly is arranged to limit the rotation of the inner sampling tube 2. When sampling, the inner sampling tube 2 is rotated to align the inlet port with the sampling port, so that the seed sample can enter the sampling cavity. When the sampling is completed or not performed, the inner sampling tube 2 is reversely rotated to close the sampling port, so that the seed sample at different depths cannot enter the sampling cavity, thereby improving the accuracy of the seed sample.

[0037] Closing and sampling: when the seed sample collected in the collecting bottle 4 is enough (the amount of seed sample in the collecting bottle 4 can be observed directly), the collecting bottle 4 is rotated clockwise, so that the positioning member 12 abuts against the right end of the semicircular groove 11, at this time the sampling tube 2 closes the sampling port, and then the outer sampling tube 1 is pulled out.
[0038] Sample export: after the sampling is completed, the end cap 5 is unscrewed, and the seed sample in the collecting bottle 4 is poured into the sample bag, and the sampling process is completed.
