Place the core tube 105 with the core on the second clamping bracket 208. The core tube 105 presses the second clamping plate 209. Subsequently, drive the first clamping bracket 201 to slide on the rotating bracket 102. When the first clamping bracket 201 is in contact with the core tube 105, the core tube 105 squeezes the first clamping plate 203 and the sliding column 202. The second clamping plate 209 clamps the core tube 105 through the deformation restoring force of the third spring 210. The first clamping plate 203 and the sliding column 202 clamp the core tube 105 through the deformation restoring force of the first spring 204.

The first clamping bracket 201 and the second clamping bracket 208 drive the core tube 105 to approach the limit rod 111. The limit rod 111 pushes out the core inside the core tube 105. At the same time, the wiping cloth 108 wipes the inner wall of the core tube 105. While pushing out the sample, drive the electric cylinder 103 to work. The electric cylinder 103 drives the sliding frame 104 to move. The sliding frame 104 drives the rotating bracket 102 to rotate on the base 109. The rotating bracket 102 drives the core tube 105 towards the recycling box 101. Gravity causes the core in the core tube 105 to fall. Drive the cam 205 to rotate. The cam 205 drives the shock plate 206 to reciprocate on the first clamping bracket 201. The shock plate 206 knocks on the first clamping bracket 201. The first clamping bracket 201 drives the core tube 105 to vibrate, increasing the speed at which the core sample falls.
