Title: ROAD ROLLER WITH ADJUSTABLE REFLECTION DEVICE
Abstract:
Provided is a road roller with an adjustable reflection device, comprising a frame (1), a travelling mechanism, a rolling structure, an operator cabin (2) and a control system. The travelling mechanism is provided on two sides of the frame; the operator cabin is provided above the frame; the rolling mechanism is provided at the front end of the frame; the rolling mechanism comprises a supporting frame (3) and a rolling wheel (4); telescopic rods (7) are provided on two sides above the front end of the supporting frame; and reflection mirrors (8) are provided on the telescopic rods. The control system comprises a controller, a position signal acquisition circuit, a driving circuit, a hydraulic lifting device and a motor, wherein an output end of the position signal acquisition circuit is connected to an input end of the controller; an output end of the controller is connected to an input end of the driving circuit; and an output end of the driving circuit is connected to an input end of the motor and an input end of the hydraulic lifting device respectively. With the road roller with the adjustable reflection device, the safety of road rolling work can be increased through the automatically adjustable reflection mirrors and the working efficiency is improved.
