Paver Having Dowel Bar Inserter with Automated Dowel Bar Feeder |
摘要 |
A paver for laying down a strip of concrete and inserting therein dowel bars parallel to the strip. A dowel bar inserter orients the bars and places them into the concrete. A pair of transport chains transverse to the travel direction extends across a width of the inserter. Pairs of generally L-shaped opposing cups hold the bars so that they can drop downwardly from the cups towards the strip. The chains move in a single direction. A dowel bar holding magazine, above the chains, stores bars, and gravitationally moves the bars towards the chains for pick-up by cups as the chains move the cups past a bar loading station. Elastic bands extend about a bar engaging surface defined by a wheel and resiliently bias the bars moving along the chain turn-around section against the wheel. |
