<p>A machine to distribute a mixture of more than one material, the mixing of the various components taking place in the machine itself, has a frame with tractor hitching points (2) and a hopper (3). A partition (4) surmounted by a hinged plate (6) divides the hopper. At the bottom of the hopper is a line of openings (8 & 8'), for each compartment (7, 7'), shut or partially shut by slides (9). Distributor wheels (10) in housing (11) are driven at an adjustable speed and feed the materials into a small hopper (12) for feeding into ducts (14) connected to a fan (15) through ducts (16), constricted at a point (17) just before the hopper outlet orifice (13), causing a lowering of pressure which sucks the material out of the hopper (12). The main hopper may have several sub-division.</p> |
