As a Bulldozer Manufacturer, share with you. Bulldozer is an earthmoving engineering machine capable of excavating, transporting and abandoning rock and soil. It is widely used in open-pit mines. For example, it is used for the
construction of dumping grounds, leveling of automotive dumping grounds,
accumulation of scattered ore rocks, leveling work flat plates and construction sites. It is used not only for auxiliary work but also for main mining work.
For example stripping and mining of sand deposits, traction and boosting of
scrapers and plows, and other earthmoving machinery to reduce the stripping step
height when there is no transportation mining method.
China Bulldozer is a major machine for earthmoving engineering machinery. It is divided into two types of crawler and tire according to the walking mode. Because there are fewer tire bulldozers. This article mainly describes the structure and working principle of crawler bulldozers. The basic operations of bulldozer excavation are: A. soil shovel B. soil transport C. soil unloading. Crawler Dozer is mainly composed of engine, transmission system, work equipment, electrical parts, cab and hood. Among them, the mechanical and hydraulic transmission systems include torque converters, coupling assemblies, planetary gear-type power shift transmissions, central transmissions, steering clutches and steering brakes, final transmissions, and travel systems. Bulldozers use mechanical transmission or hydraulic mechanical transmission systems with torque converters. A few also use hydraulic transmission systems. The power output mechanism drives the working pump, variable-speed torque-variable hydraulic system variable-speed pump, steering brake hydraulic system steering pump in the hydraulic system of the working device by means of gear transmission and spline connection; the sprocket represents the final transmission mechanism of the two-stage spur gear transmission (Including left and right final drive assemblies); track system including track assembly, trolley frame and suspension assembly.
Way of walking
Bulldozers can be divided into two types, crawler and tire. Tracked bulldozers have large traction, low ground pressure (0.04 to 0.13 MPa), strong climbing ability, but low driving speed. Tired bulldozers have high driving speed, flexible maneuverability, short operating cycle time, convenient transportation and transfer, but small traction force, and are suitable for situations that require frequent site changes and field work.
Transmission crawler bulldozer
It can be divided into two types: general type and special type. The universal type is a model that is produced according to standards and is widely used in earthwork. The special type is used in specific working conditions, including wetland bulldozers and marshland bulldozers that use triangular wide track pads to reduce the ground specific pressure, amphibious bulldozers, underwater bulldozers, cabin bulldozers, unmanned bulldozers, high prototypes and high Bulldozers operating in wet conditions.
