This utility model discloses an adjustable negative pressure boiler slag sampling device. A plug is installed at the open end of an elliptical cross-section sampling container, which is eccentrically connected to the container via an eccentric rotating shaft. The elliptical cross-section sampling container is fixedly connected to a pull ring handle unit via a spoon handle. The pull ring handle unit includes an opening and closing linkage mechanism and a limit adjustment mechanism. The opening and closing linkage mechanism includes a pull ring, a connecting shaft, and a return spring. The connecting shaft is installed inside the hollow spoon handle, with one end connected to the pull ring and the other end connected to the eccentric rotating shaft. The return spring is sleeved on one end of the connecting shaft, which has a raised guide shaft. The limit adjustment mechanism is located at one end of the spoon handle and has an oblique spiral guide groove. The raised guide shaft is slidably installed within the spiral guide groove. This utility model features a simple and stable process, improves sampling efficiency, and is adaptable to different negative pressure intensities, effectively preventing slag from being sucked back under negative pressure.
