It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, one embodiment of the present invention is: the utility model provides a shot-blasting machine top sealing device, includes shot-

blasting chamber

1, and 1 openly installs door leaf 2 through the hinge in shot-blasting chamber, and roof 3 is installed at 1 top in shot-blasting chamber, offers on the roof 3 to be used for the current breach 4 of lifting hook, is located all slide on the roof 3 of the breach 4 left and right sides and be equipped with closing plate 5, two arcwall face 6 has been seted up to one side that closing plate 5 is relative, and arcwall face 6 is the S-shaped structure, two arcwall face 6 on the closing plate 5 cooperatees and seals breach 4, arbitrary first recess 7 has been seted up on the upper portion of arcwall face 6 of closing plate 5, is equipped with sealed pad 8.

Specifically, the sealing gasket 8 is fixed on the inner wall of the first groove 7 by adhesive bonding through a sealant.

Through the arcwall face 6 of seting up the S-shaped structure in 5 relative complex one sides of closing plate, the stroke distance that the dust was escaped by sealed face has been increased to seal 8 setting on the upper portion of arcwall face 6, because the shot in the shot-blasting chamber 1 can not get into sealed face, avoided sealed 8 that seal to receive the impact of shot, sealed not fragile, prolonged sealed life who fills up, the leakproofness is good, can effectively avoid the dust in the shot-blasting chamber to escape.
