Vacuum mud suction barrel

The invention discloses a vacuum mud suction barrel, and belongs to the field of mechanical equipment development. The vacuum mud suction barrel comprises a top cover, a cylinder and a bottom mud discharging door which form a cavity, a swinging arm supporting seat on the outer wall of the cylinder, a mud discharging door swinging arm with the two ends respectively connected to the bottom mud discharging door and the swinging arm supporting seat, a mud suction pipe penetrating through the outer wall of the cylinder, a lifting lug plate at the upper end of the top cover, a vacuum pump joint penetrating through the top cover, a spraying head fixing piece on the outer wall of the cylinder, and a high-pressure water spraying head connected to a spraying head. According to the vacuum mud suctionbarrel, water flow is ejected through the high-pressure water spraying head on the outer wall of the mud suction barrel, so that the soil around a buried wire pipe is slurried to form a mud-water mixture; meanwhile, the vacu
