Design method of key structure parameters of broaden chippings distributor used in road construction

Based on mechanic analysis and experiment,the angle between the guide grooves and level,the width of the groove,the end radian of the distributor and the chippings bestrewing quality influenced by the velocity are studied.A broaden chippings distributor is designed and tested.The result shows that the bestrewing precision of the experiment machine is ±1.2%,which is better than that of the divided plane chippings distributor.5 figs,9 refs.
