The invention discloses a novel rapid mounting pneumatic vibrator, and relates to the field of pneumatic vibrators. At present, most pneumatic vibrators are trouble to
mount, large in gas consumptionamount, small in exciting force, short in service life, easy to damage and the like. The pneumatic vibrator comprises a base, a
machine base, a front end cover, a rear end cover, a middle shaft, an eccentric rotating inner casing
pipe and an eccentric rotating outer casing
pipe; an
air chamber and a sliding groove are formed in the center and the outer side of the middle shaft, the side, located on the front end cover, of the middle shaft is provided with a connection port for connecting the
air chamber and an air source, a side air outlet is formed in the
air chamber and leads to the slidinggroove, a sliding plate capable of closing and opening the air outlet of the air chamber is arranged in the sliding groove, a rapid mounting structure is arranged between the
machine base and the baseand can be detachably connected, the rapid mounting structure comprises a rapid positioning structure and a bolt type rapid fixing mechanism capable of turning over, and the bolt type rapid fixing mechanism can be rotatably connected to the base. According to the pneumatic vibrator, the
gas consumption amount can be effectively reduced, the exciting force is improved, and starting and exhaust effect of the vibrator can be better ensured.
