The technical scheme that its technical problem that solves the utility model adopts can also be:

The left end of caput is the semicircle capitiform, the left end of caput housing is the hemisphere that has boss, rod body and blast pipe elasticity cylindrical body for curling, rigid backbone is a rigid disc, there is the centre bore of fixed center blast pipe at the center of disk, return air hole is arranged around the centre bore, vibrating rotator is that left end has groove side and wears cylinder jaggy, axial eccentric part at vibrating rotator has 3---5 return air holes, have in the side of vibrating rotator and the caput boss axial notch that is complementary, in the axial notch of vibrating rotator, sealing plate is installed.

The beneficial effects of the utility model are:

1, be power source with the high-pressure blast, solved the explosion-proof problem in the construction of colliery, simple in structure, easy to maintenance, prolong 2 times application life.

2, monomer weight of the present utility model has only 3.6kg, greatly reduces working strength of workers, and construction cost reduces by 20% on year-on-year basis.
