A dust dispersion apparatus, comprising: a support (K) for supporting a receptacle (Q) containing dust, the receptacle (Q) having a leading edge and at least one wall; an exit (B); a feeding tube (J) that communicates with the outlet (B), the feeding tube (J) structured and arranged to deliver dust from the receptacle (Q) to the outlet; and a receptacle impact device which has a plurality of stable positions and comprising a movable mounted three-lobe wheel (N) with a central axle protruding on one or more sides, the wheel is axially constrained by rods protruding from a lower surface of the apparatus or a fragment thereof, in which the grooves in these rods can restrict or limit the total movement of the wheel axle and can also allow it to move up and down vertically, the wheel can be free to rotate and also move up and down in the grooves and can be prevented from moving axially substantially or from side to side, a spring (O) is positioned to cause a thrust of each side of the axle so that it causes thrust of the three-lobe wheel upwards and to push the impact member of the receptacle to a stable position, the three-lobe wheel (N) positioned within the support such as a receptacle is inserted lo (Q) on the front edge support of the same contacts a wheel lobe that causes the wheel (N) to move from an initial starting position and compresses the spring, storing energy in it, causes a maximum spring compression, after which the additional insertion of the receptacle (Q) causes the receptacle impact device to release the stored energy in a sudden rotation of the wheel which causes a wheel lobe to impact the receptacle, the device of impact of receptacle is further configured such that, then the withdrawal of the receptacle from the holder of the impact member of the receptacle is left in a position that resembles the initial starting position such that the impact device is ready for insertion of another receptacle or a new one. |
