Description

Technical Field

[0001] The utility model relates to the technical field of loader engine protection, in particular to a loader engine protection structure. Background Art

[0002] A loader is a heavy mechanical equipment used for moving and loading materials; they are usually used in construction sites, ports, warehouses, mines and other places to handle various types of goods and materials, such as soil, sand, gravel, ore, etc. When a loader is used nowadays, an engine protection mechanism is usually used to protect the engine from damage and ensure the reliable operation of the loader.

[0003] A Chinese patent with announcement number CN217023682U discloses a protective device for a loader drive engine. The loader drive engine and the protective box are designed as an integrated whole. By opening heat dissipation vents on both sides of the protective box and cooperating with a heat sink and a plurality of heat dissipation fins, the loader has a good heat dissipation effect when traveling. When passing through a flooded section of road, two sealing cover plates are lowered to seal the engine to prevent accumulated water from flooding into the engine and causing damage, and the protective performance is good. However, it is difficult to adjust the angle of the heat dissipation fins during use of the existing device, which may result in limited heat dissipation efficiency. Under different working conditions, the heat dissipation requirements may change, and the inability to adjust the angle may result in the inability to effectively adapt to these changes, thereby affecting the heat dissipation effect. At the same time, it is difficult to achieve a more precise heat dissipation effect. The fixed-angle heat dissipation fins increase the limitations of the existing device. Summary of the invention
