Two Heads Busy (also known as multi-functional construction vehicle or backhoe loader) is a kind of construction vehicle combining the functions of excavator and wheel loader, which is able to carry out a variety of operations such as digging, loading and transporting on the construction site. The following is the working principle of two-head busy:
Power system: The two-head busy is usually powered by a diesel engine, which transmits power to the hydraulic pump and wheels through the transmission system.
Hydraulic system: The pressure oil produced by the hydraulic pump is distributed to each hydraulic actuating element, such as hydraulic cylinder and hydraulic motor, through the control valve to drive the working device and travelling device.
Working device: The working device of the two-end busy includes the moving arm, bucket rod and bucket at the digging end and the loading arm, linkage and bucket at the loading end. These parts achieve the digging and loading operation through the movement of hydraulic cylinders.
Travelling device: The travelling device of two-head busy includes driving wheel, guiding wheel, track or tyre. The wheels are driven by hydraulic motors to move the vehicle forward, backward and turn.
Operating system: The operator controls the hydraulic system by means of a joystick or button to drive the working and travelling devices to complete various operations.
Electrical System: The electrical system is responsible for providing power to the lighting, dashboard, sensors and other electronic equipment to ensure the safe and efficient operation of the vehicle.
Cooling System: The cooling system is used to maintain the normal operating temperature of the engine and hydraulic system to prevent overheating.
Lubrication system: The lubrication system provides lubricant to all moving parts, reducing wear and prolonging service life.
Safety Protection: Two Head Busy is equipped with various safety protection devices, such as overload protection, tilt protection, etc., to ensure safe operation.
In a word, the working principle of two-head busy is to realise efficient and multi-functional operation in construction site through the coordinated work of many systems, such as power system, hydraulic system, working device, travelling device, operating system, electric system, cooling system, lubrication system and safety protection.
