s3, hammering the quadrangular prism (5) again, enabling the quadrangular prism (5) to descend to the height of one sampling box (24) to cut off the sampled soil, withdrawing the sampling box (24) to the storage box (29), starting the double-head hydraulic cylinder (20) in the moving plate (6), driving the two clamping plates (23) to clamp the quadrangular prism (5), and enabling the second motor (17) to rotate reversely to pull the quadrangular prism (5) out of the soil to finish the sampling process;
s4, after the moving plate (6) continuously moves upwards to be separated from the quadrangular prism (5), the double-head hydraulic cylinder (20) on the turntable (4) is started, the quadrangular prism (5) is clamped through the clamping plate (23), the first motor (18) is started to drive the turntable (4) to rotate clockwise 90 degrees, the quadrangular prism (5) is made to be horizontal, the control switch is closed, the spring (28) resets, the push plate (25) is pushed to push soil in the sampling box (24) into the corresponding collecting box (12), and the collecting process is completed.
