The operator then activates the first cylinder 31 and the servo motor 34 so that the moving cylinder 32 and the lifting cylinder 36 move downward. The operator activates the second cylinder 51, and as the piston rod of the second cylinder 51 extends, the opening and closing angle of the grapple 42 gradually increases due to the depth of the dovetail groove 6 increasing.

When the grab 42 is about to contact the soil to be sampled, the piston rod of the second cylinder 51 is contracted at this time, and the opening and closing angle of the grab 42 is gradually reduced. The sampling portion 422 begins to collect soil until the two grapples 42 are fully closed, at which point sampling is complete.
