The utility model discloses a multifunctional soil sampling suite, and relates to the technical field of soil detection, the multifunctional soil sampling suite comprises a soil
shovel cylinder and a multifunctional soil sampling mechanism, the upper side of the soil
shovel cylinder is provided with the multifunctional soil sampling mechanism, through the arrangement of the multifunctional soil sampling mechanism, when the multifunctional soil sampling suite needs to be used, a cylinder top limiting block and a detachable cover are buckled with each other; when the soil
shovel cylinder is used, force can be transmitted through the buckling state of the detachable cover and the cylinder top limiting block, and when the soil shovel cylinder collects desired soil, the detachable cover can be taken down, so that the soil in the soil shovel cylinder is taken out relatively completely, damage to soil layering after soil collection is reduced, and the soil shovel cylinder is convenient to use. The detachable cover and the
barrel top limiting block can be limited and fixed through the
barrel top connecting buckle and the top cover connecting buckle through the connecting bolts, and the problem that when the soil shovel
barrel is taken out, the soil shovel barrel falls into the soil due to the fact that the buckle fixing capacity between the detachable cover and the barrel top limiting block is insufficient is solved.
