A Wide Flow Asphalt Weighing and Spraying System

Abstract

The invention relates to the field of road building engineering machinery in particular to low-content asphalt mixture production equipment of an asphalt mixing station.The low-content asphalt mixture production equipment mainly solves the problems that an asphalt-macadam mixture which is quite low in asphalt content cannot be produced through a common asphalt mixing station, and the effect that both common asphalt concrete and the asphalt-macadam mixture can be produced through the same asphalt mixing station is achieved.The low-content asphalt mixture production equipment mainly comprises an asphalt supplying system, a weighing system, an asphalt sprinkling system and a control system, and a double-flow asphalt supplying system which can supply two different flows is adopted as the asphalt supplying system; the weighing system weighs materials output by the asphalt supplying system; a double-flow asphalt sprinkling system which can sprinkle two different flows is adopted as the asphalt sprinkling system; the control system controls asphalt supply of the asphalt supplying system and asphalt sprinkling of the asphalt sprinkling system according to output signals and material distribution commands of the weighing system.

Description

technical field [0001] The invention relates to the field of road construction machinery, in particular to the asphalt supply, weighing and spraying technology of an asphalt mixing station. Background technique [0002] With the rapid development of traffic, road grades are constantly improving, and asphalt gravel is used more and more in high-grade roads. Asphalt macadam pavement has good flatness, high strength, low vehicle noise, long life, and lower cost than hot-mix asphalt mixture, so it is used more and more in expressways, trunk roads and urban roads. In order to reduce the impact of rigid and semi-rigid roadbed cracks on the road surface, more and more designs are made to use asphalt macadam to lay the foundation surface of heavy traffic roads. Especially in road maintenance, the use of asphalt gravel sealing technology to repair road cracks, repair slight ruts on the road surface, improve the smoothness of the road surface, prolong the service life of the road sur...

AI Technical Summary

Problems solved by technology

Therefore, most of the asphalt macadam mixing machines are small and medium-sized mixers without grading machines, which cannot control the mixing quality of asphalt macadam mixture.
