摊铺机刮板传动链的主要功能是将在摊铺机料斗中的物料传送到熨平板前端的螺旋分料器的凹槽内,再由螺旋分料器将物料向两端输送,实现摊铺机对物料的摊铺。传送到螺旋分料器凹槽内的物料的高度需控制在一定范围内。如果凹槽内物料高度太低,则会引起螺旋布料不均匀,进而影响摊铺效果和效率;而如果物料高度太高,则会加大牵引负载,增加发动机功率消耗,长期运转会增大设备损耗。料位控制元件多采用两种结构形式:一种为机械式料位传感器,另一种为超声波传感器。前者控制的灵敏度低,但价格
The main function of the paver scraper drive chain is to transfer the material in the paver hopper to the groove of the spiral distributor at the front end of the screed and then deliver the material to both ends by the spiral distributor, Paving the material paving. The height of the material conveyed to the groove of the spiral distributor needs to be controlled within a certain range. If the height of material in the groove is too low, it will cause uneven spiral cloth, thus affecting the paving effect and efficiency; and if the material height is too high, it will increase the traction load, increase engine power consumption, long-term operation will increase the equipment loss. Level control components and more use of two structural forms: one for the mechanical level sensor, and the other for the ultrasonic sensor. The former control of low sensitivity, but the price
