Hydraulic milling and dredging machine is a kind of multifunctional construction machinery, its main function is to carry out digging and milling operations. The hydraulic milling machine adopts hydraulic system control, and uses the milling head attached to the hanging arm for milling. At the same time, it can also be equipped with different caliber milling head and digging bucket, which is used to carry out various digging, leveling and shaping operations. It is suitable for all kinds of corral, road, wall construction and hydraulic engineering fields under the mine hydraulic milling machine.
The working principle of hydraulic milling and digging machine is the use of hydraulic system, through the pressure of liquid to achieve the action of mechanical parts, to achieve the operation of machinery. The hydraulic system of hydraulic milling and digging machine mainly includes engine, hydraulic pump, hydraulic motor, hydraulic cylinder and dispenser and other components. The working flow of the hydraulic system: after the machine starts, the engine drives the hydraulic pump to work. The pump presses the hydraulic oil into the cylinder, and the stamping cylinder begins to produce thrust to drive the milling cutter forward. At the same time, the flow direction and pressure of hydraulic oil flow are changed through the distributor, so as to control the flow in and out and distribution of hydraulic oil, and realize the precise control of machine action. The hydraulic cylinder can control the upper and lower, left and right directions of the hanging arm at the same time to ensure the normal work of the milling cutter and the digging bucket.
Hydraulic milling and digging machine has the following advantages:
1. Powerful power: the engine power of the hydraulic milling and digging machine is large, and the hydraulic pump can provide enough power to bear greater load.
2. Flexible and reliable: the hydraulic milling and digging machine has high mobility and flexibility, and the hydraulic oil flow is controlled by the distributor operation to realize the precise control of the machine action, and the reliability is high during the operation.
3. Versatility: hydraulic milling and digging machine is a kind of multifunctional construction machinery, which can complete a variety of engineering operations such as digging, milling, water conservancy, road construction and so on.
4. Easy maintenance: the structure of hydraulic milling and digging machine is simple and easy to maintain. Engineers can maintain the machine by checking the hydraulic parts and replacing the lost parts.
In short, hydraulic milling and digging machine is a very practical engineering machinery, through the control of hydraulic oil flow to achieve the working principle, has strong power, flexible and reliable, multi-functionality and easy maintenance and other advantages, become an indispensable mechanical equipment for modern engineering construction.
