MULTI-PURPOSE HIGHWAY CONSTRUCTION DEVICE

A multi-purpose highway construction device. The thickness of lime laid on a highway can be adjusted by adjusting the thickness of the lime output on a conveyor belt (6) and a speed ratio of the lime output speed to the traveling speed of a machine frame (1). The two adjustment modes are used to work together so that the adjustable range of the thickness of the lime laying is large. The two adjustment modes are linked together for adjusting. The scale of the thickness of lime powder laid on the dial (16) is determined according to a transmission ratio and the height adjustment of a thickness baffle plate (7), and the effect of precisely adjusting the laying thickness of the lime powder can be achieved. The adjustment of both the thickness baffle plate (7) and the speed ratio is unlimited, thereby ensuring the laying thickness accuracy of the lime, and the adjustability thereof is strong. The two adjustment modes can be alternatively carried out by means of a power shaft (13), the linkage is good, and it is ea
