Description

TECHNICAL FIELD

[0001] The utility model belongs to engineering machinery technical field, especially a bulldozer front face device. BACKGROUND

[0002] A bulldozer is a heavy engineering machinery widely used in earthwork engineering, construction and road construction. Its main function is to push, move and level the land or other materials. The bulldozer is usually equipped with a large flat plate (called a bulldozer plate) which can be lifted and tilted by a hydraulic system to adapt to different working needs. In engineering construction, the bulldozer is an important earthwork machinery, and its main function is to move and level the soil. However, the bulldozer often faces various external environmental challenges when working on site, especially when working on uneven ground, obstacles such as stones and gravel frequently appear.

[0003] The front face of the bulldozer is usually the location of its engine and important components, so once the front face is hit, the consequences may not only be cosmetic damage, but also may cause failure of the engine and other critical components. This not only increases the cost of maintenance and repair, but also may delay the construction progress and affect the efficiency of the entire project. The existing design of the bulldozer front face has deficiencies in impact resistance and protection performance, often unable to effectively absorb and disperse the impact force generated by the collision. This limits the adaptability and safety of the bulldozer in complex site environments. Therefore, how to enhance the impact resistance of the bulldozer front face and improve its reliability in harsh working conditions has become a problem to be solved in the current engineering machinery field.
