Example (b):
as shown in fig. 1 and 2, the utility model provides an air ducting of electric excavator hydraulic oil radiator cooperates with radiator 1 and uses. The radiator 1 is provided in front of the excavator. The radiator 1 is provided with an air outlet 11 for horizontally discharging air. The air outlet 11 points to the cab, so that hot air exhausted by the radiator 1 enters the cab, and further influences the environment in the cab.
The air guide device of the hydraulic oil radiator of the electric excavator comprises an air guide cover 2. The wind scooper 2 includes a wind deflector 22 and two side plates 21 disposed on opposite sides of the wind deflector 22. The air deflector 22 and the two side plates 21 are combined into a groove shape. The side plate 21 away from the air deflector 22 is connected to the outer wall of the heat sink 1 by screws. The groove-shaped air guiding cover 2 is positioned at the air outlet 11 of the radiator 1. The gap between the air guide plate 22 and the radiator 1 is gradually reduced from the upper end to the lower end of the air guide plate 22.
The utility model discloses an when electric excavator hydraulic oil radiator's air ducting used, the hot-blast of 1 exhaust of radiator was blockked by wind scooper 2. Under the flow guiding effect of the air guide cover 2, hot air flows upwards along the air guide cover. This effectively prevents the hot air level discharged from the radiator 1 from blowing toward the cab. The environment of the cab is effectively ensured.
In the present embodiment, the heat sink 1 is provided with a drive motor 12. The tail of the driving motor 12 is provided with a heat dissipation port. The air guide plate 22 is provided with a through hole 23 in cooperation with the driving motor 12. The heat radiation port of the drive motor 12 faces the passage hole 23. This allows good heat dissipation to the drive motor 12 through the holes 23.
In this embodiment, the bottom of the air deflector 22 is provided with a discharge opening. The air deflector 22 is provided with a sealing plate 3 at the discharge outlet. The sealing plate 3 is hinged to the air deflector 22. The sealing plate 3 is connected to the outer wall of the heat sink 1 by a tension spring 4. The sealing plate 3 is tensioned to the discharge opening by a tension spring 4.
The working environment of the excavator is provided with particulate matters such as dust or broken stone. The impurities falling into the wind scooper 2 can be well discharged by arranging the discharge outlet. The sealing plate 3 is arranged to seal the bottom of the air guide cover 2, so that the influence of hot air flowing out from the bottom of the air guide cover 2 on the environment of the cab is avoided. The elasticity of the extension spring 4 is small, so that a small amount of sundries fall into the air guide cover 2, and the sealing plate 3 pulls the extension spring 4 to open the discharge opening of the sealing plate 3. Thereby facilitating the discharge of sundries. When the sundries are discharged, the sealing plate 3 is closed by the extension spring 4.
In this embodiment, the sealing plate 3 is provided with a plurality of drain holes. This enables rainwater to be discharged in time when falling to the wind scooper 2.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
