Device for forming concrete specimens

A device for forming concrete specimens comprising:

• concrete feeding means (2) comprising a discharge mouth (20);
• support means (3) suitable for supporting at least a first and/or a second form, said discharge mouth (20) and the force of gravity directing the concrete flowing out of the feeding means (2) towards said support means (3);
• first vibrator means (5) suitable for generating the vibration of at least the contents of the first and/or second form;
• the concrete feeding means comprising a tank that is intended for containing the concrete and which acts as a storage unit;
• the support means (3) comprising a first and a second zone (31, 32) that are suitable for supporting respectively the first and second form;
• said feeding means (2) and said support means (3) being reciprocally movable so as to assume at least a first and a second configuration;
• in the first configuration said discharge mouth (20) and gravity directing the outflowing concrete towards said first zone (31), in the second configuration said discharge mouth (20) and gravity directing the concrete flowing out of the feeding means (2) towards said second zone (32);
• the feeding means (2) comprising dosing means (9) for dosing the amount of concrete to allow to flow through the discharge mouth (20);
• the tank of the feeding means (2) comprising:
• i) an exit opening (83) for the concrete which is connectable to said discharge mouth (20) through a conduit (84), the exit opening (83) for the concrete lying at one end of the conduit (84);
• ii) a lower bottom (82) which is raisable and lowerable with respect to the exit opening (83);,
• in at least one configuration the exit opening (83) being at a greater height than the lower bottom (82);
• the dosing means (9) comprising means (85) for raising/lowering the bottom (82) of the tank.
