沥青洒布车在喷洒作业时,需根据喷洒施工要求更换适宜的沥青喷嘴。喷洒沥青时,沥青喷嘴线性喷口要将液态沥青喷洒成扇形,这就要求整车几十个喷嘴线性喷口与沥青洒布车前进方向保持统一夹角,以便对作业面形成双重或三重洒布。1.改进原因改进前,喷嘴管与喷嘴芯之间没有定位装置,喷嘴芯可360°自由转动,喷嘴芯线性喷口无法准确定位,操作者大都凭借经验调整喷嘴芯线性喷口与
Asphalt spray truck in the spraying operation, according to spray construction requirements to replace the appropriate asphalt nozzle. Spraying asphalt, the asphalt nozzle linear nozzle to liquid asphalt spray fan, which requires the vehicle dozens of nozzle linear nozzle and the asphalt distribution truck to maintain a uniform angle in the forward direction in order to form a double or triple on the operation of sprinkle cloth. 1. Improvement reasons Before the improvement, there is no positioning device between the nozzle tube and the nozzle core. The nozzle core can rotate 360 ° freely, and the nozzle core linear nozzle can not be positioned accurately. Most of the operators adjust the nozzle core linear nozzle and
