Auxiliary dust falling and crushing device for heading machine

The invention discloses an auxiliary dust falling and crushing device for a heading machine, which comprises a cutting mechanism, and the cutting mechanism comprises a connecting base fixedly mounted on a heading machine main body, a heading head arranged on the connecting base, and a water supplementing pipe arranged on the outer side of the connecting base; and the first rotating assembly comprises a first gear connected with the heading head. A second gear moves along the outer side of a first gear, blocky objects crushed by a heading head can enter the position between the heading head and a dust falling assembly, a spiral structure is arranged on the surface of the heading head and can drive the blocky objects to move backwards, the whole heading head is conical, the blocky objects are extruded and crushed through the smaller and smaller distance between the heading head and the dust falling assembly, and the dust falling efficiency is improved. Meanwhile, due to the arrangement of the protective baffle,
