Classification And Function Of Excavator Bucket

According to the working mode, the excavator bucket is divided into backhoe bucket and front shovel bucket. Generally, backhoe bucket is commonly used.

According to the different mechanical action principles, it is divided into front shovel, backhoe, grab and pull shovel.

According to the performance of its structure and material, it is divided into standard bucket, reinforced bucket and mine bucket

According to different working conditions and functions, it is divided into earth bucket, rock bucket, soil loosening bucket, ditch bucket, grid bucket, grab bucket, cleaning bucket, inclined bucket, etc

According to the different mechanical actions, it is divided into front shovel, backhoe, grab and pull shovel.

The front shovel of the excavator is hinged at the end of the bucket rod and driven by the oil cylinder. During operation, the excavation force is from bottom to top, and the excavation track is often in an arc. It is suitable for excavation of sand, gravel, coal mine and other operations above the parking surface.

Excavator Backhoe: articulated with the bucket rod and driven by the oil cylinder, the excavation force is from top to bottom during operation, and the excavation track is in a circular arc. It is suitable for excavation of soil layer, sand and gravel, coal mine and other construction operations below the parking surface.

The grab bucket of the excavator is like a shell, and the hydraulic cylinder is used to drive the opening and closing of the grab bucket like a shell to grasp the materials, or the rope winding poplar is cut into the materials vertically according to its own weight for mechanical grasping; It is generally used for building foundation pit excavation, deep pit excavation and loading of loose materials such as coal, sand, mud and gravel. It is especially suitable for excavation or loading on one side of ditch or restricted space.

The dragline of the excavator is in the shape of dustpan, with tooth base plate and bucket teeth. During operation, the bucket is thrown on the excavation surface, the shovel teeth cut into the soil layer by their own weight, and then the bucket is pulled by the guide cable for excavation. After the excavation is full, the bucket is lifted by the lifting cable, the unloading point is adjusted by turning the steering table, and the bucket is overturned for unloading. The soil below the parking surface can be excavated, but the excavation accuracy is poor.

Excavator bucket is divided into standard bucket, reinforced bucket and mine bucket according to the performance of structure and material.

The standard bucket is made of domestic high-quality high-strength structural steel Q345B. The characteristics of the standard bucket are: the bucket mouth area is large and has a large stacking surface, so it has a high filling coefficient; Save operation time and high efficiency. Suitable for light operation environment such as excavation of general clay and loading of sand, soil and gravel.

The reinforced bucket is made and reinforced with high-strength wear-resistant steel materials for high stress and vulnerable parts on the basis of the standard bucket; The tooth base plate and side edge plate of vulnerable parts are made of domestic high-quality high-strength wear-resistant steel NM360, and the plate is thickened to prolong the service life. It inherits all the advantages of the standard bucket and greatly improves the strength and wear resistance. The applicable environment is excavation of hard soil, gravel, gravel loading and other heavy-duty operations.

A reinforcing plate is added at the bottom of the mining bucket; Add side guard; Install the protective plate and adopt the double arc design at the bottom of the bucket to increase the grounding clearance of the heel and reduce wear; The gap adjustable sleeve device is adopted at the connection with the stick; Sweden HARDOX ultra-high strength wear-resistant steel is selected to prolong the service life of the product several times; Bucket teeth are special bucket teeth for rocks. Make the product more reliable, better mining performance and more prominent economy. Hard rock and mixed stone excavation environment: applicable to hard rock and sub wind; Loading of hard rock and ore after blasting.

According to the working conditions and functions, the excavator bucket can also be divided into earth bucket, rock bucket, soil loosening bucket, ditch bucket, screen bucket, grab bucket, cleaning bucket, inclined bucket, etc.

Earth bucket: it is generally used in light operation environment such as clay excavation 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; Save operation time and high efficiency.

Rock bucket: used for excavation of hard stones, secondary hard stones and wind fossils mixed in the soil; Loading of hard rock and ore after blasting. High strength wear-resistant steel, better excavation performance and more prominent economy.

Soil loosening bucket: it is used for construction in hard soil or frozen soil. It generally has single or multiple teeth. The bucket teeth are sharp and easy to break the soil.

Ditch bucket: it is applicable to the excavation of ditches of various shapes. The ditch excavation is formed at one time without trimming, and the operation efficiency is high.

Screen fighting: it is applicable to the excavation of relatively loose materials. The excavation and separation are completed at one time. It is widely used in municipal, agricultural, forestry, water conservancy and earthwork projects.

Grab: vertical grab, suitable for foundation pit excavation, deep pit excavation of building foundation and loading of loose materials such as coal, sand, mud and gravel, especially for excavation or loading on one side of ditch or restricted space.

Cleaning bucket and inclined bucket: applicable to the trimming of slopes and other planes and the large-capacity desilting and cleaning of rivers and ditches. The inclined bucket can change the inclination angle of the cleaning bucket through the oil cylinder, which greatly improves the work efficiency.
