AUTOMATICALLY REGULATED HEATING SYSTEM FOR PAVING SCREED

摘要

An automatic heating system is for a screed assembly of a paving vehicle, the screed assembly including a screed plate (5). The heating system includes an electric heater connected with the screed assembly and having a heating element (13) disposed proximal to the screed plate (5). The heater is configured to apply thermal energy to the screed plate (5) when current flows through the heating element (13). An electric power supply (14) is mounted on either the paving vehicle or the screed assembly and is connected with the heater. The power supply (14) is configured to generate electrical current flow through the heating element (13). Further, a control system is connected with the screed assembly and electrically connected with the heater. The control system is configured to automatically adjust current flow through the heating element (13) so as to regulate the temperature of the screed plate (5). Preferably, the control system includes a temperature sensor, an actuator and a microprocessor.
