沥青喷嘴高度自动控制装置
摘要：
本实用新型涉及一种沥青喷嘴高度自动控制装置，包括基座和安装在基座上的控制器，所述基座下端设置有喷洒杆，所述喷洒杆通过安装在基座上的固定杆一和固定杆二与基座连接，所述基座上且位于喷洒杆两侧位置分别安装有高度传感器一和高度传感器二，所述基座上安装有用于带动喷洒杆升降的液压缸一和液压缸二，所述喷洒杆上设置有喷嘴；所述控制器与高度传感器一、高度传感器二、液压缸一和液压缸二连接，所述高度传感器一、高度传感器二将检测到的高度变化信号反馈给控制器，所述控制器发出控制信号给液压缸一和液压缸二。本实用新型能够实现沥青喷嘴随路况的变化、车载的高度变化自动升降，提高了沥青喷洒的均匀性和洒布精度，保证了施工质量。
摘要（英）：

The utility model relates to an automatic altitude control device for a bitumen nozzle, which comprises a base and a controller installed on the base, wherein the lower end of the base is provided with a spraying rod; the spraying rod is connected with the base through a first fixed rod and a second fixed rod which are installed on the base; and a first altitude sensor and a second altitude sensor are respectively installed on the base and positioned at both sides of the spraying rod. A first hydraulic cylinder and a second hydraulic cylinder which are used for driving the lifting of the spraying rod are installed on the base; the spraying rod is provided with a nozzle; the controller is connected with the first altitude sensor, the second altitude sensor, the first hydraulic cylinder and the second hydraulic cylinder; altitude change signals detected by the first altitude sensor and the second altitude sensor is fed back to the controller; and the controller emits control signals to the first hydraulic cylinder and the second hydraulic cylinder. The utility model can realize that the bitumen nozzle can be automatically lifted according to the changes of road conditions and loading altitudes; the uniformity and the distribution precision of the bitumen nozzle are improved; and the construction quality is ensured.
