Top ends at coupling shaft 5 is fixed with top bucket dish 7.

In frame 1, offer pilot hole 6, in the interior sliding plug of pilot hole 6, have guide pole 18, in the bottom of guide pole 18, be fixed with described vacuum (-tight) housing 9.

The course of work of the present utility model is as follows:

A, steel drum put in place;

B, vacuum (-tight) housing 9 are descending under the drive of vacuum (-tight) housing lift cylinder 11;

The piston rod of c, top bucket cylinder 3 stretches out, and crimping of steel drum position is pressed onto O-ring seal;

D, by vacuumizing in 12 pairs of steel drum buckets of vacuum-pumping pipeline in bucket, by covering outside the interior and steel drum perimeter of 14 pairs of vacuum (-tight) housings of the outer vacuum-pumping pipeline of interior bucket 9, vacuumize simultaneously;

While vacuumizing in steel drum bucket, need open the first vacuum pump 19 and the first Pneumatic reversal valve 21, vacuum tightness in steel drum bucket is evacuated to 50Pa, after setting value, close the first Pneumatic reversal valve 21;

While vacuumizing outside the interior steel drum of vacuum (-tight) housing 9 perimeter, need open the second vacuum pump 20 and the 3rd Pneumatic reversal valve 23, the tenth Pneumatic reversal valve 30, the second vacuum pumps 20 employing rotary-vane vaccum pumps, the outer vacuum tightness of bucket in cover is evacuated to 1500Pa; After setting value, close the 3rd Pneumatic reversal valve 23, the tenth Pneumatic reversal valve 30;
