The utility model relates to the technical field of soil
moisture infiltration instruments, in particular to a monitoring device for measuring
grassland soil
moisture infiltration rate, which comprises an inner ring and an outer ring, a protective cover is arranged at the bottom ends of the inner ring and the outer ring, a first annular groove and a second annular groove are arranged on the protective cover, the inner ring is connected with the first annular groove in an inserting manner, and the second annular groove is connected with the outer ring in an inserting manner. The outer ring is connected with the second annular groove in an inserted mode, the bottom end of the inner ring and the bottom end of the outer ring are each connected with an
insertion ring in an inserted mode, the bottom end of the inner ring and the bottom end of the outer ring are each connected with an installation ring in a welded mode, the bottom ends of the
insertion rings are provided with blade feet with triangular bottom end sections in a welded mode, and the inner ring and the outer ring are provided with measuring structures. The inner ring and the outer ring are more easily inserted into
grassland soil through the design of the wall breaking structure, the installation resistance is reduced, the installation efficiency of the inner ring and the outer ring is improved, meanwhile, the inner ring and the outer ring are convenient to take, and the transfer convenience of the inner ring and the outer ring is improved.
