The dipper arm of the excavator is also called the eagle beak arm, which is named after its shape and structure resemble the "eagle beak". Dipper arm play a huge role in the excavation of weathered fossil engineering projects. Compared with the traditional breaking hammer operation, the rock arm working with the ripper has obvious advantages of high efficiency, low loss and low maintenance.
Dipper arm are front-end equipment of excavators, which are usually designed, produced and installed by manufacturers according to the size of the excavator. Therefore, the models of excavator Dipper arm are customized on demand.
1 main purpose
The dipper arm of the excavator is also called the eagle beak arm, which is specially designed for the processing of weathered rock and shale. Under normal circumstances, the ripper with the standard arm cannot work, and the working efficiency of the breaker is relative to that of the ripper. Low, unable to meet engineering needs and create greater profits. The work of the dipper arm , because the overall arm is shortened and heavier, can greatly increase the excavation force of the excavator, and can overcome the harsher working environment.
2 Design process
1.The design engineer will first use 2D and 3D software to assist in designing the design drawing of the dipper arm. At the same time, the design system will be used to simulate the actual action of the excavator to ensure that the designed product is feasible and has good operational performance.
2.Production engineers will carry out stress analysis, material selection, technical and technological planning and design work according to the drawings. After completing the above steps, start cutting, cutting, welding, polishing and painting, and finally complete the complete set of procedures for the dipper arm of the excavator.
3 Precautions for purchase
1.The working conditions of the excavator are very bad, so there are quite high requirements for the material of the dipper arm of the excavator. Normally, formal manufacturers will use new high-strength steel for production. Priority materials include high-strength steel HG785, strength manganese steel Q345 or Q550D, etc. Similar steel materials are stable, solid and durable, and become the first choice for large-scale engineering machinery manufacturing materials;
2.The choice of dipper arm needs to be customized according to the size of the excavator. At the same time, concrete and iron sand will be added to the large and small arms to increase the excavator's digging strength during the modification of the dipper arm, which can overcome the harsher working environment.
