Abstract
An automated concrete block machine including a mold cavity, a feedbox driven between retracted and extended positions and depositing concrete in the mold cavity when at the extended position, a cutoff bar, and a drive system coupled to and driving the cutoff bar in a direction of movement of the feedbox such that a distance between at least a portion of the cutoff bar and a top of the mold varies so that the cutoff bar removes varying amounts of concrete deposited in the mold cavity so that a depth of concrete remaining in at least a portion of the mold cavity varies so as to be unevenly distributed in a desired fashion in the direction of movement of the feedbox.
Claims15
An automated concrete block machine comprising:
- a mold including a mold cavity;
- a feedbox driven between retracted and extended positions and depositing concrete in the mold cavity when at the extended position;
- a cutoff bar;
- and
- a drive system coupled to and driving the cutoff bar in a direction of movement of the feedbox such that a distance between at least a portion of the cutoff bar and a top of the mold varies so that the cutoff bar removes varying amounts of concrete deposited in the mold cavity so that a depth of concrete remaining in at least a portion of the mold cavity varies so as to be unevenly distributed in a desired fashion in the direction of movement of the feedbox.
A concrete block machine comprising:
- a mold including a mold cavity;
- a feedbox driven between refracted and extended positions and depositing concrete in the mold cavity;
- at least one track which is fixed relative to the mold, wherein a distance between the track and a top of the mold varies in a direction of movement of the feedbox;
- and
- a cutoff bar, including a moveable cutoff element, which is driven such that the moveable cutoff element follows the at least one track and removes varying amounts of concrete deposited in the mold cavity so that a depth of concrete in portions of the mold cavity corresponding to the moveable cutoff element vary in a desired fashion in a direction of movement of the feedbox.
