Tobacco screening is with vibrations sieve

The utility model aims at providing a tobacco screening is with vibrations sieve, aim at solve traditional sieve pipe tobacco degree of consistency when filtering and do not reach the problem that all requires, which comprises a substrate, set up a mesh on the base plate, mesh type of being rectangle structure, the one end downwardly extending of mesh is equipped with the hyoplastron, the hyoplastron is the rectangle and its projected area on the base plate equals the half the of mesh area, the orientation and the discharge gate of hyoplastron belong to opposite direction, its arris of one end relative with the hyoplastron on the mesh forms the arc arris for the arc, this arc arris for use hyoplastron lower extreme mid point on the base plate projective point as the circular arc in the centre of a circle, form the structure that hyoplastron lower extreme mid point equals to this arc arris department each point distance, the utility model discloses simple structure equals that the assurance keeps length even f
