[0013] 1. For this mud suction device for oil exploitation, by arranging a mud-water separation mechanism, both the feed pipe and the water outlet pipe are externally connected to pipelines. When the suction pump is started, the suction force of the suction pump creates a negative pressure inside the box body, sucking the mud into the inside of the feed pipe.

Then the flowing water enters the connecting pipe from the funnel, then enters the suction pump, and finally is discharged from the water outlet pipe. When the motor is started, the motor drives the first transmission rod, the second transmission rod, the third transmission rod and the front rotating rod to rotate through gear transmission.

[0014] 2. For this mud suction device for oil exploitation, by arranging a mud discharging mechanism, the silt falls inside the box body and drops into the inside of the groove. When the output shaft of the motor rotates, it drives the rotating column to rotate. The groove with silt rotates to the lower side, and the silt is discharged from the mud outlet, so that the silt inside the box body can be discharged to prevent it from accumulating inside the box body.

[0015] 3. For this mud suction device for oil exploitation, by arranging a cleaning mechanism, some silt adheres to the inner side wall of the box body and will not slide off. In this way, the valve is rotated to adjust the moving direction of the flowing water. The flowing water enters the water delivery pipe, then enters the inside of the annular pipe, and then sprays out from the spray heads, so that the inside of the box body can be cleaned.

A scraper 23 is fixed in front of the funnel 19 inside the box body 6. The feed pipe 11 and the water outlet pipe 31 are both externally connected to the pipeline, and the pump 18 is started.
