依据其机械动作的不同，分为正铲、反铲、抓斗、拉铲。
According to the different mechanical action, it can be divided into front shovel, backhoe, grab and dragline.
挖掘机正铲铰装于斗杆端部，经过油缸驱动，作业时挖掘力由下向上，挖掘轨迹常呈弧线，适于开挖停机面以上的沙土、碎石、煤矿等作业。
The excavator is hinged on the end of the stick and driven by the oil cylinder. The excavation force is from the bottom to the top, and the excavation track is usually in an arc, which is suitable for excavation of sand, gravel, coal mine and other operations above the shutdown surface.
挖掘机反铲：与斗杆连杆铰接，经过油缸驱动，作业时挖掘力由上向下，挖掘轨迹呈圆弧线，适于开挖停机面以下的土层、砂石、煤矿等施工作业。
Backhoe of excavator: it is hinged with the stick rod and driven by the oil cylinder. During the operation, the excavation force is from top to bottom, and the excavation track is in a circular arc. It is suitable for the excavation of soil layer, sandstone, coal mine and other construction operations below the shutdown surface.
挖掘机抓斗似贝壳形，应用液压油缸驱动抓斗似贝壳的张合来抓取物料或是绳索卷扬垂直依自重切入物料机械抓取；普通应用于建筑基坑挖掘、深坑挖掘及煤、沙、坭、碎石等较松懈物料的装载，特别适用于沟或受限制的空间的一侧停止挖掘或装载。
The grab of excavator is similar to the shell shape, and the hydraulic oil cylinder is used to drive the grab like the shell to grab the material or the rope winch is used to cut into the material vertically according to the self weight and grab the material mechanically; it is generally used in the excavation of building foundation pit, deep pit excavation and the loading of loose materials such as coal, sand, clay and gravel, especially suitable for the excavation or loading of one side of ditch or restricted space.
挖掘机拉铲呈畚箕形，有齿座板与斗齿。作业时将铲斗掷于挖掘面上,铲齿借自重切入土层，然后经过引索拉曳铲斗挖掘，挖满后由提升索将斗提起，经过转向台转向调理卸土点，铲斗翻转卸土。可挖停机面以下的土壤，但挖掘精度差。
The dragline of excavator is dustpan shaped, with tooth base plate and bucket teeth. During the operation, the bucket shall be thrown on the excavation surface, the shovel teeth shall cut into the soil layer by self weight, and then the bucket shall be pulled by the guide cable for excavation. After the excavation is full, the bucket shall be lifted by the lifting cable, and the bucket shall be turned to adjust the unloading point through the steering platform, and then the bucket shall be turned over for unloading. The soil below the shutdown surface can be excavated, but the excavation accuracy is poor.
挖掘机挖斗按构造材质性能分为：规范型挖斗、增强型挖斗、岩石型挖斗。
According to the structure and material properties, the excavator bucket can be divided into standard type bucket, reinforced type bucket and rock type bucket.
规范型挖斗资料选用国产高强度构造钢Q345B，规范斗特性:斗口面积较大，具有较大的堆装面，因而具有较高的装满系数；节省作业时间，效率高。适用环境普通黏土的挖掘和沙、土、砾石的装载等轻作业环境。
The standard bucket is made of high-quality and high-strength structural steel Q345B. The characteristics of the standard bucket are as follows: the bucket mouth has a large area and a large stacking surface, so it has a high filling coefficient; the operation time is saved and the efficiency is high. It is suitable for the excavation of common clay and the loading of sand, soil and gravel.
增强型挖斗是在规范型挖斗的根底上对高应力和易损部位采用高强耐磨钢资料停止制造和补强；易损部位齿座板和侧刃板资料选用国产高强度耐磨钢NM360，板材加厚，延长运用寿命。继承了规范斗的一切优点并较大的进步了强度和耐磨性。适用环境为挖掘硬土、碎石、砾石的装载等重载作业。
The reinforced type bucket adopts the high-strength wear-resistant steel data for the high stress and vulnerable parts on the base of the standard type bucket to stop the manufacturing and reinforcement; the tooth base plate and side edge plate data for the vulnerable parts adopt the domestic high-quality high-strength wear-resistant steel NM360, which thickens the plate and prolongs the service life. It inherits all the advantages of the standard bucket and greatly improves the strength and wear resistance. The applicable environment is heavy load operation such as excavation of hard soil, gravel, gravel loading, etc.
岩石型挖斗底部增加加固板；增加侧护板；装置防护板，在挖斗的底部采用双圆弧设计，以增加踵部的接地间隙，减轻磨损；在与斗杆衔接处采用间隙可调理套安装；选用瑞典HARDOX超高强度耐磨钢，使产品寿命延长了几倍；斗齿用岩石专用斗齿。使产品的牢靠性高、挖掘性能更好、经济性更为突出。适用环境：土中混有较硬石块、次坚石、风化石的挖掘；坚石、爆破后的矿石的装载等重作业。
The bottom of the rock type bucket is provided with reinforcement plate, side guard plate, and protection plate. The double arc design is adopted at the bottom of the bucket to increase the ground clearance of the heel and reduce the wear. The gap adjustable sleeve is adopted at the joint with the bucket rod for installation. The Swedish HARDOX ultra-high strength wear-resistant steel is selected to prolong the product life by several times. The bucket tooth is specially used for rock. So that the product has high reliability, better mining performance and more prominent economy. Applicable environment: excavation of hard rock, secondary hard rock and aeolian fossil mixed in soil; loading of hard rock and blasted ore and other heavy operations.
挖掘机挖斗按工况功用作用还分为土方斗、岩石斗、松土斗、水沟斗、筛搏斗、抓斗、清洁斗、倾斜斗等。
According to the working conditions, the excavator bucket can also be divided into earth bucket, rock bucket, loose bucket, ditch bucket, sieve bucket, grab bucket, cleaning bucket, tilt bucket, etc.
土方斗：普通用于粘土的挖掘和沙、土、砾石的装载等轻作业环境。斗口面积较大，具有较大的堆装面，因而具有较高的装满系数；俭省作业时间，效率高。
Earth hopper: it is generally used for excavation of clay and loading of sand, soil and gravel. The bucket mouth has a large area and a large stacking surface, so it has a high filling coefficient; the operation time is saved and the efficiency is high.
岩石斗：用于土中混有较硬石块、次坚石、风化石的挖掘；坚石、爆破后的矿石的装载等重作业。强度耐磨钢，挖掘性能更好、经济性更为突出。
Rock bucket: it is used for excavation of hard rocks, secondary hard rocks and wind fossils in the soil; loading of hard rocks and ores after blasting and other heavy operations. The strength and wear-resistant steel has better digging performance and more outstanding economy.
松土斗：用于硬土或是冻土施工作业，普通有单齿或多齿，斗齿尖利，容易破土。
Loose soil bucket: it is used for hard soil or frozen soil construction. Generally, it has single or multiple teeth. The bucket teeth are sharp and easy to break.
水沟斗：适用于各种外形沟渠的开挖，沟渠开挖一次成形，无需修整，作业效率高。
Ditch bucket: it is suitable for the excavation of all kinds of ditches. The excavation of the ditch takes shape at one time without trimming, and the operation efficiency is high.
筛搏斗：适用于别离较松懈物料的挖掘，挖掘与别离一次完成，普遍用于市政、农业、林业、水利、土石方工程。
Screen fight: it is suitable for excavation of loose materials. Excavation and separation are completed at one time. It is widely used in municipal, agricultural, forestry, water conservancy and earth rock works.
抓斗：垂直抓取，适用于建筑地基的基坑挖掘、深坑挖掘及煤、沙、坭、碎石等那些较松懈物料的装载等，特别适用于沟或受限制的空间的一侧停止挖掘或装载。
Grab: vertical grab, suitable for foundation pit excavation, deep pit excavation and loading of loose materials such as coal, sand, clay, gravel, etc., especially suitable for stopping excavation or loading on one side of ditch or restricted space.
清洁斗及倾斜斗：适用于斜坡等平面的修整及河道、水沟的大容量清淤、清洁工作，其中倾斜斗能经过油缸来改动清洁斗的倾斜角度，大大进步工作效率。
Cleaning bucket and inclined bucket: it is applicable to the trimming of slopes and other planes, and the dredging and cleaning of rivers and ditches with large capacity. The inclined bucket can change the inclined angle of the cleaning bucket through the oil cylinder, greatly improving the working efficiency.
