s3, when the collection cylinder (1) enters an underground set position, the controller controls the lifting motor (40) to start, and the lifting motor (40) drives the lifting screw rod (401) to rotate, so that the sampling box (42) moves along the lifting screw rod (401); when the sampling box (42) moves to the set position of the lifting screw rod (401), the start and stop motor (44) is controlled by the controller to be started, and the second crown gear (440) on the start and stop motor (44) is utilized to drive the second worm (441) to rotate, so that the baffle (14) is separated from the sampling groove (13); finally, the controller controls the sampling motor (43) to start, the first crown gear (430) on the sampling motor (43) is utilized to drive the first worm (431) to rotate, so that the adjusting sleeve (41) pushes the sampling box (42) and the lifting screw rod (401) to move to one side of the sampling groove (13) under the action of the driving toothed plate (410), and finally the sampling box (42) enters the beach geological soil to collect samples;
s4, after the sample collection is finished, the sampling box (42) and the lifting screw rod (401) are taken out of the collecting cylinder (1) at the same time, and the sample in the sampling box (42) is transferred.
10. The mudflat geological monitoring sample collection device according to claim 3, characterized in that the upper end of the support plate (20) is provided with a balancing weight (22).
