PRESSURE SENSOR FOR A SCREED PLATE APPARATUS
A screed system includes a screed plate and a plurality of pressure sensors coupled to the screed plate and configured to sense a weight of the screed plate. A method for positioning screed system includes receiving pressure information from a plurality of pressure sensors engaged with a screed plate; determining a pressure distribution across the screed plate based on the pressure information; determining, based on the determined pressure distribution across the screed plate, an angle of attack of the screed plate; and adjusting the angle of attack of the screed plate.
Automated nulling screed assembly
A screed assembly is disclosed. The screed assembly has a screed frame that includes a main screed. Attached to the main screed is a drop arm that is used to attach the screed assembly to a work machine. An actuator device of the screed assembly adjust the main screed from a neutral position to a nulled position by rotating the main screed around an axis of the pivot pin. The screed assembly may further include a controller that determines whether the main screed is in the neutral position and adjust the main screed to the nulled position by sending a null adjustment signal to the actuator device, and the actuator device moving the main screed from the neutral position to the nulled position in response to the null adjustment signal.
SCREED ASSEMBLY WITH FUNCTIONAL COUPLING BETWEEN A HEIGHT ADJUSTMENT DEVICE FOR A SCREED PLATE CARRIER AND A TILTING DEVICE FOR A SECONDARY SCREED PLATE ATTACHED TO THE SCREED PLATE CARRIER
A screed assembly for a road paver comprises a main screed and a secondary screed. The main screed comprises a main screed plate for contact with paving material. The secondary screed comprises a screed plate carrier and a secondary screed plate for contact with the paving material. The secondary screed plate is attached to the screed plate carrier so as to be tiltable about a tilting axis. The screed assembly comprises a height adjustment device configured to lower or raise the screed plate carrier relative to the main screed. The screed assembly further comprises a tilting device configured to change a tilting angle of the secondary screed plate about the tilting axis.
Side-step concrete screeding apparatus
An apparatus for screeding concrete to produce a level finished surface includes a frame assembly having a pair of spaced vertically oriented stabilization legs secured to the front end thereof supporting a generally horizontal front member. An extendable boom assembly is secured to said frame assembly at a first end and to a screed head at a second end. A side-step assembly includes an actuator with an extendable arm secured to said boom assembly to impart generally lateral motion.
A Paver
A paver mountable to a vehicle to provide propulsion and hydraulic power to the paver, wherein the paver includes: a drive system coupling for mounting the vehicle to the paver; hydraulic mounts to connect with hydraulic power from the vehicle; a solids handling assembly for receiving paving material and for delivering paving material to a paving site; a screed assembly with a screed plate which is hydraulically adjustable in extension, height and grade; wherein, paving material delivered to the paving site is shaped by the screed assembly as the paver is propelled forward to produce a paved surface.
Screed assembly comprising a work station
A screed arrangement includes a screed assembly (1) for laying a road surface (3), the screed assembly (1) configured to determine a working width (W), viewed in the working direction (R), for laying of the road surface (3). The screed arrangement further includes a working station (9) for an operator (P) mounted on the screed assembly (1). The working station (9) is mounted on the screed assembly (1) in a vibration-decoupled manner, such that the transmission of vibrations from the screed assembly (1) to the working station (9) an be reduced or prevented.
Systems, apparatuses and methods for material flow control for wide-width paving
A paving machine for wide-width paving includes a conveyor system, an auger system disposed adjacent to the conveyor system, a screed adjacent to the auger system, and sensing circuitry configured to sense paving material height at one or more of an entrance to the conveyor system and a front side of the auger system to sense or detect underflow or overflow conditions of the paving material. The sensed heights are communicated to control circuitry of the paving machine, through signals from the sensing circuitry, and control circuitry controls rate of movement of one or more of the conveyor system and the auger system.
Flexible screed
The present invention relates to a screed for a paving machine that includes a flexible smoothing plate, a vertex block a first actuator, and a second actuator. The flexible smoothing plate is provided with a longitudinal length and an outer longitudinal end. The vertex block is located on top of the flexible smoothing plate. The first actuator is connected to the outer longitudinal end and adapted to selectively adjust an elevation of the outer longitudinal end so that the outer longitudinal end of the flexible smoothing plate forms a berm by flexing about the vertex block and extending upward at an angle relative to an inner portion of the flexible smoothing plate. The second actuator is connected to the vertex block and configured to adjust the length of the berm by selectively repositioning the vertex block along the longitudinal length of the flexible smoothing plate.
Paver extension bracket device
A paver extension bracket device automates extension and retraction of a paver platform extension to correspond to and be driven by extension and retraction of a pre-existing laterally extendable paver mechanism. The device includes a bracket configured for coupling to a laterally extending paver mechanism of a paver. A post is coupled to and extends from the bracket such that said post is configured for coupling to a paver platform extension such that the paver platform extension is extended and retracted respectively by extension and retraction of the paver mechanism.
CONTROL SYSTEM FOR A ROAD PAVER
The present disclosure relates to a control system for a road paver. The control system comprises a camera system configured to generate image data of an environment of the road paver. The control system further comprises a controller electronically connected to the camera system. The controller is configured to receive the image data from the camera system, and to apply an object recognition process on the received image data to identify an edge line serving as a reference line for a mat to be laid by the road paver, and to determine a three dimensional position of the identified edge line. The controller may automatically control the road paver, and may assist an operator to control the road paver based on the identified position of the edge line.
