Abstract
A screed assembly includes an auger, a cylinder, and a vibratory screed. The screed assembly may be included in an undercarriage. The undercarriage may be coupled to a carriage. The carriage may travel along a length of a framework. One or more sensors may be used to determine height information of the screed assembly relative to a surface to be paved. One or more actuators may be used to selectively adjust the height of the screed assembly based on the height information.
Claims22
A screed assembly configured to finish a working surface of concrete in a plurality of transverse passes, comprising:
- an auger configured for rotation around a first rotational axis, the auger configured to shift an excess portion of the concrete in a paving direction forward of a current transverse pass;
- a cylinder configured for rotation around a second rotational axis, the second rotational axis offset from the first rotational axis, the cylinder including a front surface offset behind a front surface of the auger relative to the paving direction, the cylinder configured to compact the working surface;
- and
- a vibratory screed mounted behind the cylinder, the vibratory screed having a rear surface offset behind a rear surface of the cylinder relative to the paving direction, the vibratory screed configured to provide a final finishing of the working surface.

An undercarriage assembly, comprising:
- an upper beam;
- a screed assembly comprising:
- an auger configured for rotation around a first rotational axis, the auger configured to shift an excess portion of concrete of a working surface in a paving direction forward of a current transverse pass;
- a cylinder configured for rotation around a second rotational axis, the second rotational axis offset from the first rotational axis, the cylinder configured to compact the working surface;
- and
- a vibratory screed mounted behind the cylinder, the vibratory screed configured to provide a final finishing of the working surface after compaction by the cylinder;
- and
- a forward mast and a rearward mast, each including an inner mast portion and an outer mast portion;
- wherein both the forward mast and the rearward mast couple the upper beam with the screed assembly for adjusting a distance between the upper beam and the screed assembly.
6 more elements
A finisher machine comprising:
- a framework configured to be positioned transversely to a working surface of concrete, the framework configured to travel in a paving direction coincident to the working surface;
- a carriage configured to travel along a substantial length of the framework in a plurality of finishing passes in a transverse direction to the paving direction;
- an undercarriage mounted to the carriage, the undercarriage comprising:
- a screed assembly, the screed assembly configured to finish a portion of the working surface in each of the plurality of the finishing passes;
- and
- at least one actuator, the at least one actuator configured to adjust a height of the screed assembly relative to the working surface;
- wherein during a finishing pass of the plurality of finishing passes the carriage is configured to move the screed assembly from an initial finishing position on the framework to a final finishing position on the framework for finishing a portion of the working surface between the initial finishing position and the final finishing position;
- wherein between the plurality of finishing passes the at least one actuator is configured to raise the screed assembly such that the screed assembly does not interfere with the working surface, the carriage is configured to move the screed assembly from the final finishing position on the framework to the initial finishing position on the framework, and the at least one actuator is configured to lower the screed assembly;
- wherein the screed assembly comprises:
- an auger configured for rotation around a first rotational axis, the auger configured to shift an excess portion of the concrete in the paving direction forward of the finishing pass;
- a cylinder configured for rotation around a second rotational axis, the second rotational axis offset from the first rotational axis, the cylinder configured to compact the working surface;
- and
- a vibratory screed mounted behind the cylinder;
- the vibratory screed configured to provide a final finishing of the working surface after compaction by the cylinder.
