The manufacturer of long arm excavators teaches you to identify the classification of excavator buckets.
According to its different mechanical principles, it can be divided into forward shovel, back shovel, grab and pull shovel.
According to its different structure and material properties, it can be divided into standard type, reinforced type and rock type.
According to the different working conditions, it can be divided into earthwork bucket, rock bucket, loosening bucket, ditch bucket, grip bucket, cleaning bucket, tilting bucket and so on.
According to the different mechanical action, it can be divided into forward shovel, back shovel, grab and pull shovel.
The front shovel hinge of excavator is installed at the end of bucket rod and driven by oil cylinder. The excavation force is from bottom to top, and the excavation track is usually arced. It is suitable for excavation of sand, gravel, coal mine and other operations above the stopping face.
Excavator backhoe: Hinged with bucket rod connecting rod, driven by cylinder, excavation force is from top to bottom, excavation track is circular arc, suitable for excavation of soil, sand, coal mine and other construction operations below the stopping surface.
Excavator grab is shell-like, hydraulic cylinder-driven grab is used to grab materials or rope hoist is used to enter material mechanical grab vertically according to self-weight; it is commonly used in excavation of foundation pit, excavation of deep pit and loading of loose materials such as coal, sand, pick and gravel, especially in ditches or restricted spaces. Stop excavation or loading on one side.
The shovel of excavator is shaped like a dustpan with teeth base plate and bucket teeth. During operation, the bucket is thrown on the excavation surface. The bucket teeth are cut into the soil layer by self-weight. Then the bucket is excavated by the pulling bucket of the fuse cable. After full excavation, the bucket is lifted by the lifting rope. After turning the turntable, the bucket is turned to the regulating unloading point, and the bucket is turned over to unload the soil. The soil below the stopping surface can be excavated, but the excavation accuracy is poor.
Excavator buckets can be divided into three types according to their structural material properties: standard type, reinforced type and rock type.
Standard bucket material is Q345B, a high quality and high strength structural steel made in China. The characteristics of standard bucket are as follows: large bucket area, large stacking surface, high filling coefficient, saving operation time and high efficiency. It is suitable for excavation of common clay and loading of sand, soil and gravel.
Enhanced bucket is to stop manufacturing and reinforcing high stress and vulnerable parts by using high-strength wear-resistant steel material on the basis of standard bucket, and high-quality high-strength wear-resistant steel NM360 is selected for the data of tooth base plate and side edge plate of vulnerable parts, which can make the plate thicker and prolong the service life. It inherits all the advantages of the standard bucket and greatly improves its strength and wear resistance. It is suitable for heavy-duty operations such as excavation of hard soil, gravel and gravel loading.
Reinforcement plate is added at the bottom of rock bucket; side guard plate is added; double arc design is adopted at the bottom of bucket to increase grounding clearance of heel and reduce wear; gap adjustable sleeve is used at the connection with bucket rod; Swedish HARDOX ultra-high strength wear-resistant steel is selected to prolong the life of product several times; Rock bucket teeth for teeth. The product has high reliability, better excavation performance and more prominent economy. Applicable environment: excavation of hard rock, sub-hard rock and weathered fossil mixed in soil; loading of hard rock and ore after blasting with equal weight.
Excavator buckets can also be divided into earthwork buckets, rock buckets, loosening buckets, ditch buckets, sieve buckets, grabs, cleaning buckets, tilting buckets and so on.
Earthwork bucket: commonly used in clay excavation and sand, soil, gravel loading and other light working environment. The bucket has a large area and a large stacking surface, so it has a higher filling coefficient, saves operation time and high efficiency.
Rock bucket: It is used for excavation of hard stones, sub-hard stones and weathered fossils mixed in soil, and loading of hard stones and ore after blasting. Strength and wear-resistant steel, better excavation performance, more prominent economy.
Loosening bucket: used for hard soil or frozen soil construction operations, usually single or multiple teeth, sharp bucket teeth, easy to break.
Ditch bucket: Suitable for excavation of all kinds of shape ditches. Ditch excavation takes shape once, no need to be repaired, and operation efficiency is high.
Screening Fighting: It is suitable for the excavation of looser separated materials, excavation and separation completed at one time, and is widely used in municipal, agricultural, forestry, water conservancy, earth and rock works.
Grab: Vertical grab, suitable for foundation pit excavation, deep pit excavation and coal, sand, pick, gravel and other loose materials loading, especially for ditches or restricted space side stop excavation or loading.
Cleaning bucket and tilting bucket: It is suitable for the modification of slopes and other planes, as well as the large-capacity silt removal and cleaning of rivers and ditches. The tilting bucket can change the tilting angle of the cleaning bucket through the oil cylinder, thus greatly improving the working efficiency.
