ABSTRACT:
An apparatus for transporting loose tobacco material includes a transporting belt, equipped with a vibratory sub-assembly with independent driving elements and a feeding channel placed over the transporting belt. The vibratory sub-assembly has the form of at least two separate vibratory portions, each having at least one roller with eccentric elements and symmetrically arranged counterweights. Each of the vibratory portions has separate adjusting elements to provide independent adjustment of the magnitude and direction of vibration amplitude vector, and also has separate adjusting elements providing independent adjustment of the frequency of the transporting belt vibrations, independently of speed of the transporting belt. An additional belt conveyor having vibratory portions is mounted over the transporting belt.
