Abstract
A bell packer comprises of a rotating member combinable to a pallet for rotating the pallet, a vibrator for providing oscillatory motion, and a vibrating member engaged with the vibrator positioned apart from the rotating member for vibrating the pallet. A hopper for storing concrete slurry has an opening to a first auger and a second auger that convey the concrete slurry toward the shaft so that the concrete slurry falls to the center of a mold. A drive assembly comprises of a pair of motors configured for counter-rotation of a pair of concentric shafts with each having a gear and pulley linked by a belt wherein the pulleys are concentric with each other and the counter-rotating shafts.

A bell packer for a packerhead machine, the bell packer comprising:
- a rotating member combinable to a pallet for rotating the pallet;
- a vibrator for providing oscillatory motion;
- and
- a vibrating member engaged with the vibrator positioned apart from the rotating member for vibrating the pallet, such that rotating member is substantially isolated from vibration from the vibrating member.
A packerhead machine with a drive mechanism for rotating a shaft with a plurality of compacting rollers that compact concrete slurry in a mold, the packerhead machine comprising:
- a hopper for storing concrete slurry with an opening underneath;
- a first auger positioned on one side of the opening underneath the hopper and a second auger positioned on the other side of the opening underneath the hopper, the first auger and the second auger extending longitudinally to the shaft to deliver concrete slurry from the hopper to the shaft so that the concrete slurry falls into the mold.
A drive assembly for driving a counter-rotating roller head and long bottom for a packerhead machine, the drive assembly comprising:
- a first motor;
- a second motor;
- a first transmission engaged with the first motor;
- a second transmission engaged with the second motor;
- a first shaft engaged with the first transmission for rotating one of the roller head and the long bottom in a first direction;
- and
- a second shaft concentric with the first shaft for rotating the other of the roller head and the long bottom in a second direction.
