Dredger dewatering mechanism

The utility model relates to the technical field of dewatering mechanisms, and discloses a dredger dewatering mechanism which comprises a first box body, a second box body is fixedly arranged on one side of the first box body, a third box body is fixedly arranged on one side of the second box body, a frame body is fixedly arranged on the other side of the first box body, and a mud inlet pipe is fixedly arranged at the upper end of the first box body. And a buffer pipe is fixedly arranged in the sludge inlet pipe, an exhaust port is fixedly formed in one side of the upper end of the third box body, and a filtering mechanism is arranged at the upper end of the exhaust port in a clamped mode. According to the device, the buffer pipe, the second box and the third box are arranged, so that the impact force of sludge is relieved, the sludge at the front end can be fully precipitated, and when the sludge is precipitated, smelly or harmful gas can be generated and is discharged into the air without being treated for
