The utility model relates to a direct-pushing-type columnar soil sampler with scales, belonging to soil collection instruments in soil research. The direct-pushing-type columnar soil sampler is simple in structure and convenient to operate and consists of a sampling tube, a supporting frame, a mud pushing rod with the scales, a mud pushing sheet with the scales, a mud sampling handle and a mud pushing handle. The direct-pushing-type columnar soil sampler can be used for collecting hard upland soil and bottom mud of water-near regions. By utilizing the scales on the mud pushing rod, the depth of collected soil samples can be fast and accurately judged according to the raising height of the mud pushing handle in a sampling process, and the collected samples can maintain the features of columnar mud samples at the collection depth. When the collected soil samples are segmented, the collected soil samples are pushed out by utilizing the mud pushing rod according to the required length and the scales on the mud pushing rod and are cut along a lower hole edge of the sampling tube, the soil structure is not damaged, and an independent ruler does not need to be equipped, so that the direct-pushing-type columnar soil sampler has good practical values in research on the soil and the bottom mud of water-near regions of rivers and lakes.
