Main Purpose Of Asphalt Mixing Plant
Single bucket excavator is mainly composed of the engine, chassis, transmission system, walking device and working device, rotary device, operation control system and bridge parts.
The chassis is the framework of the whole machine, it support in the walking device. In addition to the walking device, engine, transmission and in the work components are installed on the frame. Transmission system transfer the power of the engine to work device, slewing mechanism and the walking device, can be divided into mechanical drive and hydraulic transmission. Mechanical transmission is widely used in the old excavator, and modern excavators mainly adopts hydraulic transmission transmit power. Single bucket hydraulic excavator by hydraulic pump, hydraulic motors, hydraulic cylinders, control valve and hydraulic line of hydraulic components. Working device can be in accordance with the construction requirements and work object is different for replacement.
(1) Main hoisting
It is mainly composed of drum, wire rope, chain transmission, clutch and brake, etc. For is shovel, perform the bucket, the bucket rod of expansion and the bottom of the bucket of opening and closing action; Execution for backhoe bucket out and take lead (back) action; To pull a shovel, bucket elevator and opening and closing action.
(2) Slewing mechanism
Perform turntable above all in the rotary motion
(3) Luffing mechanism
The implementation of movable arm lifting movement.
(4) Changement
Turntable rotation and motion mechanism of directional movement, so that the excavation and unloading operations.
(5) Walking mechanism
Perform mechanical driving and action.
