Method for controlling a self-propelled construction machine to account for identified objects in a working direction
A self-propelled construction machine has an image capturing unit for capturing an image of the terrain, a display unit on which the captured image is displayed, and a data processing unit. In the displayed image, objects that are relevant to the building project, for example manhole covers, water inlets or curbs, are identified and a spatial data set containing information regarding the position of the identified objects in a reference system which is independent of the movement of the construction machine is determined from the image data of the capturing unit. The construction machine is then controlled in order to carry out translational and/or rotational movements on the terrain and/or to install a structure on the terrain or to alter the terrain on the basis of the spatial data set. As a result, the previously identified objects can be taken into account in the building project.
GROUND COMPACTOR
A ground compactor for compacting ground material (10), comprising at least one compactor roller (22) rotatable on a machine frame about a roller rotation axis (W) substantially orthogonal to a longitudinal direction (L) of the compactor and a vertical direction (H) of the compactor and extending substantially in a transverse direction (Q) of the compactor, with an edge processing device (24) associated therewith for processing a side edge (38) of compacted ground material (10), wherein the edge processing device (24) comprises an edge processing disk (26) rotatably supported on a disk carrier (30) about an edge processing rotation axis (K), characterized in that the edge processing rotation axis (K) is set or can be set at a first angle of incidence (W1) with respect to the transverse direction (Q) of the compactor in the longitudinal direction (L) of the compactor.
METHODS AND DEVICES FOR PROVIDING REAL-TIME ASPHALT DENSITY AND MOISTURE CONTENT PREDICTION WITH GROUND PENETRATING RADAR
Methods, apparatus, and storage medium for providing real-time asphalt density and/or moisture content prediction with ground penetrating radar. A method includes using raw data from a ground penetrating radar sensing an asphalt concrete at a location; processing the raw data to obtain processed data; determining an asphalt density of the asphalt concrete at the location based on the processed data according to an asphalt density prediction model; determining a compaction status of the asphalt concrete at the location based on the asphalt density and a target compaction threshold; and outputting the compaction status of the asphalt concrete at the location to an operator for determining whether to continue or stop compacting the asphalt concrete at the location. In another method, moisture content for cold recycling and existing asphalt concrete pavement is predicted in real-time from using raw from data of ground penetrating radar mounted on a vehicle.
Thermoelectric power generation on a paving machine
An electrically powered paving machine includes a hopper; a screed assembly; a conveying system; one or more batteries configured to power the electrically powered paving machine; a plurality of thermoelectric generators electrically connected to the one or more batteries; a potential thermal energy conversion device electrically connected to the one or more batteries; and processing circuitry. Additionally, the electrically powered paving machine controls charging the one or more batteries using electrical energy generated by one or more of the plurality of thermoelectric generators and the potential thermal energy conversion device.
GRADING ATTACHMENT FOR WORK MACHINE
A grading attachment for a work machine includes a frame defining a front end and a rear end and a roller rotatably coupled to the frame proximal to the front end of the frame. The roller defines an outer surface. The grading attachment includes a scraper assembly coupled to the frame proximal to the front end of the frame. The scraper assembly is offset to an axis of rotation of the roller. The scraper assembly includes a first scraper plate extending along the axis of rotation. The first scraper plate includes a first end surface that is proximal to the outer surface of the roller. The scraper assembly also includes a second scraper plate coupled to the first scraper plate and extending along the axis of rotation. The second scraper plate includes a second end surface that is proximal to the outer surface of the roller.
Impact compactor
The invention relates to an impact compactor which includes a first part on which at least one non-round compactor drum is rotatably mounted; and a second part which is connected to, and movable relative to, the first part. The impact compactor also includes a damping arrangement which is connected between the first and second parts and which is configured to provide a damping function for the relative movement between the first and second parts. The damping arrangement includes an outer tubular member which defines a non-circular inner channel/passage; a non-circular inner shaft member which defines a first axis of rotation and which is positioned, at least partially, in the channel/passage defined by the outer tubular member; and at least one wedge formation which is wedged between the shaft member and the tubular member. The wedge formation is at least partially resiliently deformable and is configured to resist/oppose relative rotation between the shaft member and the tubular member about the first axis of rotation. One of the members is connected to the first part, while the other member is connected to the second part.
