Abstract

A vibrating device comprises a chamber (4) inside which a shaft (13) is mounted. At least one tubular member (23) is arranged in the chamber (4) around the shaft (13) and is free to rotate with respect to the shaft (13). The shaft (13) has a groove (16) in which a vane (20) is received. The shaft (13) further has an arrangement of ducts (15, 19) for feeding a pressurised fluid towards the vane (20) so as to move the vane (20) from a retracted position (PR), in which the vane (20) is housed in the groove (16), to an extended position (PE), in which the vane (20) protrudes from the shaft (13) to come into contact with the tubular member (23). The vibrating device (39) has a contact surface (40) and the vibrating device (39) is intended to be positioned in contact with an object at the contact surface in order to vibrate the object. The shaft (13) is mounted in a fixed position in the chamber (4), so that a longitudinal central plane (P1) of the groove (16) forms an angle (A) comprised between 20° and 25° with a plane (P2) perpendicular to the contact surface (40).

Abstract

Motor-vibrator assembly for a vibrating machine having a plurality of motor-vibrators, each having a synchronous motor and at least one eccentric mass divided into two bodies fixed to two respective free ends of the shaft of the motor. The motor-vibrator assembly comprises position sensing means to sense the angular position and the angular velocity of the shafts of the synchronous motors, electronic drive devices to operate the synchronous motors and an electronic control unit, which is configured to control the electronic drive devices based on the angular positions and on the angular velocities sensed, so that the motor-vibrator assembly generates a predetermined vibratory motion.

Abstract

An aeration apparatus to ease the emptying of a mass of powdered material from any kind of container. The apparatus comprises a vibrating membrane coupled to a device for pulling and fastening it to the container wall, so that said membrane adheres to the inner surface of the container wall. The apparatus is characterized in that the inner surface of membrane has a number of grooves shaped as radial recesses formed only on the lower half of the inner surface of the membrane itself. Each radial section of any radial recess is advantageously venturi-shaped.
