Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a protective cover for an agricultural engine radiator. Background Art

[0002] An agricultural engine radiator is a device installed on agricultural machinery or vehicles to dissipate heat. Its function is to dissipate the heat generated by the engine during operation, keeping the engine running within the appropriate operating temperature range, thereby ensuring normal operation of the engine and extending its service life.

[0003] A protective cover is usually installed on the engine's radiator tank to protect the radiator tank. The existing Chinese patent with authorization announcement number CN220909807U discloses an engine radiator protective cover. The screen is installed on a mounting frame, and a sealing strip is provided on the front opening of the mounting frame to ensure the sealing effect, that is, to ensure the heat dissipation effect of the radiator tank. The screen is fixed by a pressing frame, which makes replacement of the screen convenient and quick. A retaining frame is provided outside the mounting frame to protect the screen from external damage. Depending on the design and model of the protective cover, the corresponding mounting accessories are used, usually using screws or clips to fix the protective cover to the radiator. Ensure that the screws are securely tightened, but most protective covers are hollow inside and are easily deformed and damaged when subjected to external impact, affecting normal use. Furthermore, the protective cover adopts a closed design, which makes it difficult to observe when docking the protective cover with the base, and is prone to deviation and misalignment.

[0004] In summary, the current agricultural engine radiator protective cover still has the following defects during installation and use at the user end:

[0005] (1) Most protective covers are hollow inside and are prone to deformation and damage when subjected to external impact, affecting normal use;

The cover body 1 and the base 2 are integrated into a whole through a welding process. The cover body 1 is a hollow structure and a vent is provided on the outer side for heat dissipation. The base 2 can be connected to the radiator base by bolts through the holes opened at the bottom. When assembling, the splicing seat 311 is fixed to the inner side of the cover body 1 by the splicing bolts 312 and does not contact the radiator. The support arms 314 can rotate and deflect around the splicing seat 311 as the center of the circle, and form a frame structure at the bottom of the cover body 1 through the connected branch beams 316 and the main beam 313, so that the cover body 1 is not easily deformed or damaged when subjected to external force impact.

[0040] The heat sink 4 includes a metal pick 41, which is arranged on the inner side of the base 2. A dustproof net 42 is provided between the metal pick 41 and the cover 1. The dustproof net 42 is fixedly installed on both sides of the base 2 by assembling bolts 43. The metal pick 41 is made of elastic metal. The dustproof net 42 is clamped with the base 2 through the metal pick 41 and the assembling bolts 43, and the dustproof net 42 blocks external dust and impurities from entering the cover 1, thereby ensuring the stable operation of the radiator.

When installing it with the radiator seat, by unfastening The locking engagement of the removal protrusion 325 with the U-shaped slot 322 allows the spring 324 to resume its extension, pushing one end of the push rod 323 to protrude from the positioning guide rail 321, and locking the protrusion 325 with the U-shaped slot 322 again, thereby fixing the protruding length of the push rod 323 in the positioning guide rail 321, thereby facilitating the positioning rotary cylinder 326 to be fixed to the radiator seat through the threaded engagement screws provided by itself, so that when the base 2 is in a closed state, the radiator seat is accurately positioned, and the dustproof net 42 made of elastic metal is locked with the assembly bolts 43 to complete the locking engagement of the dustproof net 42 with the base 2, so that the dustproof net 42 blocks external dust and impurities from entering the cover body 1, and corresponds to the vent in the cover body 1 through the heat dissipation holes 44, thereby ensuring air exchange inside the cover body 1 and ensuring stable operation of the radiator.
