It comprises a wind turbine consisting of a cylindrical drum of horizontal axis, provided with an inlet aperture connected to a vacuum and loading chamber. On the distal face of said chamber, the inlet is reduced to two outlets to the outside of which are connected individual suction hoses. The lower part of the chamber forms a ramp at whose lower end there is an outlet connected to the inlet of a filter pump to which the air from the tangential outlet of the turbine is reconveyed. The section of this outlet has a sudden reduction which subsequently widens. In the expansion zone, a vacuum is produced which discharges the material to be transported via a hose. <IMAGE> |
