Excavator bucket soil material is mining, ore, mining machinery, transport and loading or unloading of vehicles to the yard.
Excavator digging bucket, bucket hinge shovel is arranged on the bucket rod end, by the arm support, the mining action from the bottom to the top, the bucket tooth trajectory often curved, suitable for excavation stop surface above the soil. Bucket backhoe excavator bucket rod is hinged with the Mining Act, usually from the top down, a circular arc tooth trace, suitable for stopping the soil excavation. Mobile Edge bucket digging shovel along the boom, boom in fixed position, the bucket tooth trajectory in a straight line, thereby obtaining a mining straight surface, suitable for excavation slope, side ditch or flat ground. Dragline bucket is a dustpan shape, the bucket bottom front bucket tooth. When working, the bucket shall be thrown out in the mining face, bucket teeth by bucket heavy cut into the earth, and then by the traction Sola bucket digging, digging by the bucket full of lifting cable filed, turntable to dumping, dumping bucket flip. Excavator bucket is the ultimate working device of excavator, because of the direct and the work site as the clay, sand and gravel contact, so the requirements of wear resistance, impact resistance. At the same time as the bucket excavator is wearing parts, general engineering excavator in an average of 8 years of use will be consumed in the 3 ~ 6 bucket, so have a wide range of accessories market.
Excavator hydraulic excavator using oil pump, hydraulic cylinder, hydraulic motor and other components for power transmission. Pressure oil pump output respectively to promote the hydraulic cylinder or motor, the mechanical part of each corresponding operation. Common is the backhoe excavator (see pictures). Backhoe working, movable arm down, as a support, a bucket rod hydraulic cylinder or hydraulic cylinder loader bucket on down below the surface and make the arc movement, mining and soil, and then lift up the arm, steering soil unloading point using the rotary motor, flip bucket dump. Because of the working site and construction object is different, the same can be configured in multiple bucket excavator, but must pay attention to matching the performance, such as to improve the excavation work efficiency enhanced models can be replaced with large rock hopper, but in order to adapt to the work in the ordinary, ordinary rock type bucket into the same volume rock bucket is carefully, so as not to damage the overall performance of the bucket rod, movable arm caused by improper use of quality problems occur.
To extend its service life, in addition to ensure sufficient strength and rigidity is also put forward higher requirements on the fatigue strength and wear resistance, usually the bucket tooth design into two parts replaced, and the body are welded together called the bucket tooth base, can be removed and replaced as part of the bucket tooth.
Implement the regular maintenance of the excavator is designed, reduce the machine failure, prolong the service life of the machine; improve the use of time; improve the work efficiency, reduce maintenance cost. |
