First of all, let's understand what a spreader is. As the name suggests, the vehicle we use to spray asphalt on the road surface is the spreader. It is a kind of black road construction machinery, which is the main equipment of highway, urban road, airport and port construction. When the asphalt penetration method and asphalt surface treatment method are used to build asphalt pavement or maintain asphalt or residual oil pavement, the spreader can be used to transport and distribute liquid asphalt (including hot asphalt, emulsified asphalt and residual oil). In addition, it can also supply asphalt binder to the loose soil in place and build asphalt stabilized soil pavement or pavement base. Both ordinary and intelligent models can be used, but there are differences between them
1. First of all, we look and judge from the appearance of the car body
a. Ordinary nozzle is different from intelligent nozzle. Intelligent type with small cylinder type, while ordinary type is manual handle type, which is very simple at first sight.
b. Rear working platform: intelligent type has operation box, but ordinary spreader does not.
c. The number of nozzles of spreader will be different. The number of ordinary nozzles is generally less than that of intelligent nozzles.
2. Operation differentiation:
a. One key control operation in the cab is completed to realize zero start spraying. The spray nozzle can realize one control and one control, which can accurately adjust the spraying width and density; the ordinary type of spreader can be manually adjusted and opened one by one by human, and the spraying width can be manually controlled, so the amount of oil can not be controlled.
b. The intelligent spreader has high efficiency and fuel saving after the whole operation of one person cab, while the ordinary spreader has many uncontrollable factors, low efficiency, low spraying accuracy and fuel consumption
c. The purchase price of ordinary and intelligent vehicles is higher than that of ordinary vehicles.
d. In the scope of use, ordinary spreader is used in the construction of township roads with low road quality, while intelligent spreader is widely used.
