In this embodiment, when the hydraulic oil is input from the hole on the top of the third hydraulic housing 201a-2a, the pressure in the third hydraulic housing 201a-2a increases. When the liquid in the third hydraulic housing 201a-2a reacts against the second hydraulic pressure When the pressure of the adjusting core 201a-2d is greater than the elastic force of the second spring 201a-2e on the second hydraulic adjusting core 201a-2d, the second hydraulic adjusting core 201a-2d is pushed out of the first hydraulic adjusting core 201a-2b, and then the liquid can enter in the lifting leg 201b; when the hydraulic oil is output from the hole on the top of the third hydraulic housing 201a-2a, the pressure in the third hydraulic housing 201a-2a decreases.

In this embodiment, when the operator puts the seabed surface rock and soil sampling device into the sea, he needs to use a steel cable to hang the seabed surface rock and soil sampling device and make it slowly fall into the relatively flat seabed. When the sampling device falls into the seabed, you only need to turn on the hydraulic pump 202a to suck the hydraulic oil into the hydraulic tank 202b. At this time, the first hydraulic shell 201a-1a, the second hydraulic shell 201a-1b and the third hydraulic shell 201a-2a The pressure decreases, and the first hydraulic rod 201a-1c is lifted under the liquid pressure in the second hydraulic shell 201a-1b, driving the connecting seat 201a-1d to move upward, and then driving the first connecting plate 101c and the second connecting plate 101d to open. open, causing the first grab bucket 101a and the second grab bucket 101b to open; when the first grab bucket 101a and the second grab bucket 101b open to the maximum, the liquid pressure in the third hydraulic shell 201a-2a will increase the pressure in the hydraulic pump. 202a continues to increase until the pressure of the liquid in the third hydraulic housing 201a-2a on the first hydraulic adjustment core 201a-2b is greater than the elastic force of the first spring 201a-2c on the first hydraulic adjustment core 201a-2b. A hydraulic adjustment core 201a-2b is pulled into the third hydraulic shell 201a-2a, so that the liquid can flow out of the lifting leg 201b; the leg 201b contracts, causing the first grab bucket 101a and the second grab bucket 101b to shovel into the seabed rock and soil. until the leg 201b shrinks to its shortest position.

It should be noted that after the first grab bucket 101a and the second grab bucket 101b have shoveled the seabed rock and soil, the operator can control the hydraulic pump 202a to reverse to discharge the hydraulic oil out of the hydraulic tank 202b. At this time, the first hydraulic pump 202a The pressure in the shell 201a-1a, the second hydraulic shell 201a-1b and the third hydraulic shell 201a-2a decreases, and the first hydraulic rod 201a-1c drops under the liquid pressure in the second hydraulic shell 201a-1b, driving the connection The seats 201a-1d move downward, thereby driving the first connecting plate 101c and the second connecting plate 101d to close, so that the first grab bucket 101a and the second grab bucket 101b close; when the first grab bucket 101a and the second grab bucket 101b are completely After closing, the liquid pressure in the third hydraulic housing 201a-2a will continue to decrease under the action of the hydraulic pump 202a, until the pressure of the liquid in the third hydraulic housing 201a-2a on the second hydraulic adjustment core 201a-2d is greater than the second hydraulic pressure regulating core 201a-2d. When the spring 201a-2e exerts its elastic force on the second hydraulic adjustment core 201a-2d, the second hydraulic adjustment core 201a-2d is pushed out of the first hydraulic adjustment core 201a-2b, and then the liquid can enter the lifting leg 201b; the leg 201b extends length, so that the first grab bucket 101a and the second grab bucket 101b leave the seabed rock and soil until the leg 201b extends to its longest point; at this time, the operator can use the steel cable to pull the seabed surface rock and soil sampling device back to the sampling ship, Complete sampling.
