Classification and Function of Excavator Bucket
Excavator buckets are divided into backhoe buckets and forward buckets according to the working mode. Generally, backhoe buckets are commonly used.
According to different mechanical action principles, it is divided into forward shovel, back shovel, grab bucket and drag shovel.
According to the difference of its structure and material performance: it is divided into standard bucket, reinforced bucket and mine bucket
According to the different functions of the working conditions: it is divided into earthmoving bucket, rock bucket, soil loosening bucket, ditch bucket, grid bucket, grab bucket, cleaning bucket, tilt bucket, etc.
According to the different mechanical actions, it is divided into forward shovel, backhoe, grab bucket and dragline.
The front shovel of the excavator is hinged on the end of the stick. It is driven by the oil cylinder. During the operation, the digging force is from bottom to top. The digging track is usually an arc. It is suitable for excavating sand, gravel, coal mines, etc. above the stop surface.
Excavator backhoe: hinged to the stick linkage and driven by the oil cylinder, the digging force is from top to bottom during the operation, and the trajectory of the excavation is circular, suitable for excavation of soil layers, gravel, coal mines and other construction operations below the stop surface .
The excavator grabs a shell-like shape, and uses a liquid oil cylinder to drive the grab-like shell to open and close the material to grab the material or rope. The poplar is cut into the material mechanically according to its own weight. It is generally used for excavation of foundation pits, deep pits, and coal and sand. Loading of loose materials such as concrete, concrete, gravel, etc. is especially suitable for digging or loading on one side of a trench or restricted space.
The dragline of the excavator has a hoe shape, and has a toothed seat plate and bucket teeth. During the operation, the bucket is thrown on the digging surface, the teeth are cut into the soil layer by their own weight, and then the bucket is pulled by the puller to dig the bucket. After the digging is completed, the bucket is lifted by the hoisting rope, and the dumping point is adjusted by turning the steering table. The bucket is turned over. Unloading. The soil below the stopping surface can be dug, but the excavation accuracy is poor.
Excavator buckets are divided into standard buckets, reinforced buckets, and mine buckets according to their material properties.
The standard bucket material is made of domestic high-quality and high-strength structural steel Q345B. The characteristics of the standard bucket are: large bucket area and large stacking surface, so it has a high filling factor; saving operation time and high efficiency. Applicable environment Light clay such as excavation of clay and loading of sand, soil and gravel.
Reinforced bucket is based on the standard bucket to manufacture and reinforce high-strength and wear-resistant steel materials for high stress and vulnerable parts; the material of the seat plate and side blade of the vulnerable parts is made of domestic high-quality high-strength wear-resistant Steel NM360, the plate is thickened to extend the service life. Inherits all the advantages of the standard bucket and greatly improves the strength and wear resistance. The applicable environment is heavy-duty operations such as loading of hard soil, gravel, and gravel.
Add reinforcement plate at the bottom of the mine-type bucket; add side shields; install protective plates, use a double arc design at the bottom of the bucket to increase the ground clearance of the heel and reduce wear; the gap can be adjusted at the connection with the stick Set of equipment; the use of Swedish HARDOX ultra-high-strength wear-resistant steel, which has extended the product life several times; bucket teeth for rock teeth. Make the product high reliability, better digging performance, and more economical. Applicable environment: excavation of hard rock, sub-hard rock, weathered rock mixed in the soil; loading of hard rock, blasted ore and other heavy operations. 3G1628 Double Bevel Motor Grader Cutting Edge
Excavator buckets are also divided into earthmoving buckets, rock buckets, soil loosening buckets, ditch buckets, sieve buckets, grab buckets, cleaning buckets, tilting buckets, etc. according to the function of the working conditions. Function of Excavator Bucket
Earth bucket: Generally used for light operating environments such as clay excavation and loading of sand, soil and gravel. The bucket mouth has a larger area and a larger stacking surface, so it has a higher filling factor; saving operation time and high efficiency.Function of Excavator Bucket
Rock bucket: used for excavation of hard rock, sub-hard rock, weathered rock mixed in soil; loading of hard rock, blasted ore and other heavy operations. Strength wear-resistant steel, better excavation performance and more economical. 7D4509 11 Holes Curved Carbon Steel Boron Steel Blade
Soil loosening bucket: used for hard soil or frozen soil construction operations, generally single or multi-toothed, bucket teeth are sharp and easy to break the soil.
Water ditch bucket: suitable for the excavation of ditch of various shapes. The ditch can be excavated at one time without trimming and the operation efficiency is high. 9W6252, 9W-6252 Caterpillar Bolt On Cutting Edges
Sieve fighting: suitable for the excavation of relatively loose materials. Excavation and separation can be completed at one time. It is widely used in municipal, agricultural, forestry, water conservancy, earth-rock engineering. CAT Tractor Blade 9W2328, 9W-2328 6 Holes 5/8″ Bolts
Grab: vertical grabbing, suitable for excavation of foundation pits, deep pits, and loading of loose materials such as coal, sand, concrete, gravel, etc., especially for one side of a trench or restricted space Excavation or loading. 9J3863, 9J-3863 Caterpillar Tractor Blades
Cleaning bucket and inclined bucket: It is suitable for trimming the slope and other planes, as well as large-capacity dredging and cleaning of rivers and ditches. Among them, the inclined bucket can change the inclination angle of the cleaning bucket through the oil cylinder, which greatly improves the work efficiency. 3G2166, 3G-2166 CAT 3/4″ Holes 2FT Curved Heat Treated Grader Blade
