轮斗式挖沟机用来在Ⅰ—Ⅲ级非冻土壤上挖掘各种管道工程(如石油、电讯、城市建设、农田水利等)的沟渠。与链式挖沟机相比具有工作速度快、生产效率高、寿命长和切削力较大(因为有刚性大、强度高的环形斗轮)等优点。一、基本工作原理轮斗挖沟机属于连续式挖掘机,由拖拉机底盘和轮斗工作装置两大部分组成(图1)。机器行走、斗轮回转、铲斗连续铲挖土壤和皮带运输机排土,三个动作同时进行。斗轮11由
Bucket-type trenchers are used to dig trenches of various pipeline projects (such as oil, telecommunications, urban construction, farmland irrigation, etc.) on grade I-III non-frozen soil. Compared with the chain trencher, it has the advantages of high working speed, high production efficiency, long service life, and high cutting force (because of the large rigidity and high strength of the ring bucket). First, the basic working principle The bucket trencher is a continuous excavator, which consists of two parts of the tractor chassis and the bucket working device (Figure 1). The machine walks, the bucket wheel rotates, the shovel continuously shovels the soil, and the belt conveyer dumps soil. Three actions are performed simultaneously. Bucket Wheel 11
