Description
Technical field
The present invention relates to the radiator dedusting of agricultural machinery, engineering machinery etc., exclusion device more particularly to a kind of radiators
Automatic dust removing apparatus.
Background technology
At present due to the more sundries of the working environment of agricultural machinery, engineering machinery etc., dust, during the work time its
The radiator of engine easily by blockings such as sundries or dusts, cause engine radiating bad in addition damage engine and its
His component influences the normal work of engine or other component.Existing dust collector of engine radiator is by adjusting wind
Fan steering come blow down be attached to radiator either the sundries of other component, dust so that radiator or other component energy
Enough normal works, will not further damage engine.However, existing farm engine radiator dust-extraction unit or needs
Wind direction or design structure complexity are adjusted manually, react insensitive.
If China Patent No. is 200820089739.4, a kind of entitled practicality for the fan of adjustable wind direction on engine
New patent discloses the following contents：The axle sleeve of sharf can be fixed by being equipped on fan fixed disc, every group two, axle sleeve,
One with fluted, another without groove, blade is equipped with the axis that can be inserted into axle sleeve, and the top of axis, which is equipped with, can lock fan directional
Hole, block axis with lock pin and generate reversed wind, blow the sundries on engine water tank off.But the shortcomings that structure is to need to come manually
Wind direction is adjusted, not only poor practicability, is also easy to cause security incident.
If Chinese Patent Application No. is 201410653034.0, a kind of entitled farm engine water tank automatic dust removing apparatus
