SCRAPER BAR FOR A SCRAPER BLADE OF A ROAD MILLING MACHINE
The invention relates to a scraper bar (20) for a scraper blade (68) of a road milling machine, having a carrier (10) that comprises a front side and a rearward installation surface (17), the carrier (10) comprising a cutting-element receptacle (13), cutting elements (30) being held, serially arranged along a longitudinal axis (L) extending in a width direction of the carrier (10), on or in the cutting-element receptacle (13), and the cutting elements (30) comprising a cutting edge (35.1) that transitions indirectly or directly into a rake surface (35). In order to improve the working result, provision is made according to the present invention that at least for some of the cutting elements (30), the cutting edge (35.1) is set at least locally not parallel to the longitudinal axis (L).
Devices, systems, and methods related to extracting infill from artificial turf
A machine for extracting infill from artificial turf includes a first conveyor forming an inclined surface having movable tracks to engage and move a length of artificial turf from a first end to a second end of the machine. A rake disposed on the first end of the machine may include teeth configured to engage an underside of the turf for feeding onto the first conveyer. The machine may also include a first roller disposed above the first conveyor, where the first roller is movable to apply a downward force to a top surface of the first conveyor. The machine may further include a second roller on the second end of the machine, where the second roller includes protrusions that agitate the turf for assisting in removing infill. The machine may also include a second conveyor to receive infill removed from the turf for discharge from the machine.
PAVER STONE, BRICK AND BLOCK EXTRACTION TOOL
An apparatus for extracting a paver stone, and the like from a preset position, including a pair of lifting plates having a body containing one or more lifting aid insertion openings at one end, and at an opposing end, a blade portion having substantially concave tabs with tab edges formed along a pair of slots terminating in one or more of stress relief openings between the body and the blade, wedging a first blade between the paver and a first adjacent paver and wedging a second blade at an opposing end of a paver and a second adjacent paver, substantially compressing the tabs storing spring energy in the blades, pushing the tab edges below the bottom plane of the paver, releasing the stored spring energy thereby substantially decompressing and re-forming the tabs such that the tab edges contact and engage the underside of the paver to be extracted.
Tennis court playing surface removal device
A machine-mountable device facilitates removal of the cushioning acrylic and rubber layers overlying the concrete/asphalt base of tennis courts. The device includes: an attachment bracket, a support beam, a support plate, a scraper, and a stopper bar. The attachment bracket is configured to mount the device to any of one of several different transport machines (e.g., a loader, or forklift). The support beam is fixedly secured to the attachment bracket, and the support plate is secured to the support beam. The elongated scraper has a length between 12 and 20 inches, but is preferably between 14 and 15 inches, and optimally is about 16 inches long. The 16 inch scraper is releasably mounted to the support plate, and centered between the ends of the attachment bracket. The scraper removes the layers above the base, while the stopper bar causes the removed layers to simultaneously/automatically roll up like a carpet.
ROAD STRUCTURE, CORROSION-RESISTANT CONDUCTIVE SHEET USED FOR THE ROAD STRUCTURE, AND METHOD FOR PEELING OFF ASPHALT LAYER
A road structure, an asphalt layer of which is peeled off by electromagnetic induction heating, includes a non-thermoplastic base layer, an asphalt layer located above the base layer, a conductive sheet between the base layer and the asphalt layer, a first bonding layer that bonds the conductive sheet and the base layer; and a second bonding layer that bonds the conductive sheet and the asphalt layer. The conductive sheet is configured to generate heat based on electromagnetic induction. At least the first bonding layer is a thermoplastic bonding layer configured to be softened by the heat.
