Ocean seabed rock sampling and collecting device with crushing structure

The utility model relates to the technical field of ocean detection, in particular to an ocean seabed rock sampling and collecting device with a crushing structure, which comprises a device main body and a second connecting plate, a motor is mounted on the surface of the inner wall of one side of the device main body, and the output end of the motor is fixedly connected with a rotating rod; and the surface of the bottom end of the rotating rod is connected with a clamping mechanism. According to the rock sampling device, the clamping mechanism and the breaking mechanism are arranged, the clamping mechanism is favorable for clamping the rock needing to be sampled and conveniently determining the target rock needing to be sampled when the rock needs to be sampled, and the breaking mechanism is favorable for clamping the target rock needing to be sampled when the two groups of clamping blocks are used for clamping the rock needing to be sampled; rock clamped by the two sets of clamping blocks is knocked and smas
