DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator dustproof device for a working vehicle having a dustproof net on a front surface of a radiator of an engine.

[0002]

2. Description of the Related Art Conventionally, in a work vehicle such as a tractor, a detachable dustproof net for preventing clogging of the radiator is provided on a front surface of a radiator mounted on a front portion of a vehicle body.
There is known a configuration in which dust such as straw chips, grass nuts, and other dust and insects that are forcibly sucked into the radiator by a radiator fan is captured by the dustproof net.

[0003]

However, when the engine (radiator fan) is stopped, a part of the dust trapped in the dust-proof net falls and accumulates in the lower front part of the radiator. Also, when removing and cleaning the dust-proof net, dust attached to the dust-proof net may fall and accumulate in the lower front part of the radiator. Then, it is difficult to remove the dust that has accumulated as described above because the working space is narrow due to components such as an air cleaner and a battery disposed around the front side of the radiator. In addition, the dust remaining without being removed is wound up by the suction action of the radiator fan again, and has repeatedly been viciously cycled to adhere to the dustproof net.

[0004]
