Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator cover for an engine in a combine or a harvester.

[0002]

In the engine cover of the combine, an intake hole for sucking outside air sucked and ventilated to the radiator of the engine is formed. Since a large amount of dust and the like is contained, the straw dust and dust are removed from the outside air sucked into the engine cover to reduce the amount of the straw dust and the like sucked into the radiator, thereby reducing the engine cooling effect. Is to increase.

[0003]

According to the present invention, an engine 1 is provided.
Radiator intake cover 3 that guides intake air to radiator 2
In the lower part on the inside, a wind shield plate 6 having an air intake hole 5 arranged so as to form a ventilation passage 4 at an appropriate interval is provided, and a cleaning gutter 8 having a cleaning hole 7 at the bottom at the lower end inside the wind shield plate 6. A radiator cover, such as a combiner, provided with a guide plate 9 and a guide port 10 which are provided at the lower end portions of the ventilation passage 4 and the wind shield plate 6 so as to guide dust to flow down to the cleaning gutter 8. Configuration.

[0004]

According to the rotation of the radiator fan, outside air is sucked from the radiator intake cover 3 through the ventilation passage 4 to the radiator 2 through the intake hole 5 of the wind shield plate 6. The wind speed of the ventilation path 4 is reduced by the resistance of the wind shield plate 6 passing through the intake hole 5, so that straw dust, dust, and the like contained in the suction wind fall to the bottom and are guided by the guide plate 9 to be blocked by the guide plate 9. The air flows down from the guide port 10 at the lower end of the wind plate 6 into the cleaning gutter 8 inside. A cleaning hole 7 is provided at the bottom of the cleaning gutter 8 and is discharged downward.

As described above, between the radiator 2 and the radiator intake cover 3 that covers the outside air intake section, the wind shield plate 6 is provided.
Since the lower end inclined guide plate 9, the guide port 10, the cleaning gutter 8, and the like of the air passage 4 are disposed, dust is removed by lowering the outside air to be sucked and decreasing the flow velocity.
The configuration is simple, and clogging of dust such as straw waste in the radiator 2 can be reduced. Further, the suction force on the outer surface of the radiator intake cover 3 is also weakened, so that the suction of straw chips and the like is reduced, and the cooling effect of the engine 1 can be maintained high.

At the rear part of the vehicle body 12, a grain tank 31 for receiving and storing threshing and sorting grains taken out from the graining machine 30 of the threshing device 17, and grains sent backward from a delivery auger 32 at the bottom of the grain tank 31 Vertical auger 33 for receiving and frying, and a horizontal auger 35 for transporting the grains inherited from the vertical auger 33 and discharging the same through a discharge port 34 at the tip.
And the like. 37
Is a transport cover that covers the grain culm transport device 18.

A radiator intake cover 3 is provided outside an engine room 38 covered by the engine cover 28. A driver's seat 29 is mounted on an upper portion of the engine cover 28 as a seat floor 39, and an intake box 41 accommodating an air cleaner 40 is provided at a rear portion. 42
Is a radiator fan, which is arranged outside the engine 1, and further, a radiator 2 is arranged outside this. The radiator intake cover 3 is provided outside the engine cover 28 and forms an intake network 43 in an upper portion, and a lower portion connects the radiator 2 to an outer surface of a radiator room 44 in the interior.

A lower portion of the radiator intake cover 3 is provided with a wind shield plate 6 having an intake port 5 so as to cover the outer surface of the radiator room 44. The wind shield plate 6 and a lower portion 45 of the radiator intake cover 3 are provided. The air passage 4 is formed at an appropriate interval between the air passages 4 and so that the outside air sucked from the upper intake network 43 is sucked from the air passage 4 into the radiator room 44 through the intake holes 6 of the wind shield plate 6.

A long guide opening 10 is formed at the lower end of the wind shield plate 6 so as to extend between the front and rear ends. The dust that has descended down the guide 4 is guided by the guide plate 9 to the guide opening 10. At the lower end of the wind shield plate 6 on the radiator room 44 side, a cleaning gutter 8 for receiving dust flowing down from the guide opening 10 is formed, and a cleaning hole 7 is formed at the bottom of the cleaning gutter 8 to flow down. Let the dust fall. Reference numeral 46 denotes a handle of an armrest provided at a front upper portion of the radiator intake cover 3.

Is rotated by the wind, the outside air is guided from the intake network 43 to the ventilation path 4, and flows to the radiator room 44 through the intake hole 5 of the wind shield plate 6 and the partial guide opening 10. At this time, since the outside air descends from the upper intake network 43 to the lower intake port 5, the dust reaches the upper surface of the inclined guide plate 9 below the ventilation path 4 by this downward force, and flows down the guide port 10 to the cleaning gutter 8. In addition, the intake port 5 of the wind shield plate 6 is separated from the cooling air sucked into the radiator room 44, and the dust adsorbing force at the intake network 43 and the intake port 5 is reduced to enhance the dust separation and dust removal effect. be able to.
