Intake manifold, exhaust manifold, cooling fan 16
d, a flywheel 16e, and the like. As shown in FIG. 5, the intake manifold is the engine 16
It communicates with the air cleaner 46 fixed on the upper surface,
The air cleaner 46 is provided at the upper edge rear portion 3 of the radiator support frame 38.
Air is sucked from the space on the outer surface side of the radiator support frame 38 through the through hole i formed in 8a and the intake pipe 47. The engine cooling fan 16d
Is mounted on the front surface side of the cylinder block 16a and is configured to rotate about a rotation center axis 48 that is substantially aligned with the center of the ventilation opening 45a at the rear end of the shroud 45.

As shown in FIG. 5, a bracket 49 for fixing the related parts of the engine 16 and other parts is fixed to the U-shaped support rod member 39. In the illustrated example, the intake pipe 47, the fuel filter 50, electrical components (controller, regulator,
(A relay, a timer, etc.) is fixed, and a bendable band 52a made of metal and a pipe insertion metal fitting 52b are fixed to the U-shaped support rod member 39 to fix the step surface 21 of the control section 9. The breather pipe upright portion 53 of the fuel tank provided below is held in position by a bendable band 52a, and the tip of the upright portion 53 is bent in an inverted U shape so that its tip is inside the pipe insertion fitting 52b. It is designed to be inserted into the hole from above. Although not shown, the U-shaped support rod member 39 supports electric wires that connect the parts in the engine room and electric wires that are laid between the engine room ER and the side columns 25, if necessary. It is made to let you.

Further, as shown in FIGS. 5 and 6, an oil cooler 54 for cooling the working oil of hydraulic equipment such as the mission device 17 is arranged inside the outer side wall 36 and on the outer side of the radiator mounting frame 38. It is set up. Similar to the radiator 42, most of the oil cooler 54 except the upper part and the lower part is made into the ventilation range part h1, and is fixed to the radiator support frame 38 via the brackets 55, 55.
The oil cooler 54 is located in the ventilation range h of the radiator 42 when viewed from the side of the machine body, and the engine cooling fan 16d
It is better to position it off the rotation center axis 48, and in the illustrated example, it is positioned off the front and the oil passage of the ventilation range part h1 is oriented vertically.

Next, the operation of the main part of the combine described above will be described. When the engine 16 is started, the engine cooling fan 16d is interlocked and rotated. By the rotation of the fan 16d, the outside air flows inward from the air inlet b of the outer surface wall portion 32. This inflowing air reaches the inside of the shroud 45 through the oil cooler 54 and the ventilation range parts h, h1 of the radiator 42 through the outer vertical surface part 32a and the inner vertical surface part 32c of the outer side wall part 32, and the engine cooling fan. After passing through 16d, it is delivered to the engine 16 side.

The air flowing in this manner is used for the oil cooler 5
4 and the radiator 42, when they pass through the ventilation range h, h1, they act to remove the heat of the hydraulic oil and the engine cooling water flowing in the ventilation range h, h1 and the hot air around the engine 16 to another place. Acts to carry away.

Since the rotational speed of the engine cooling fan 16d increases as the distance from the rotation center shaft 48 increases, the ventilation capacity increases as the distance from the rotation center shaft 48 increases, and therefore the ventilation range h of the radiator 42 increases. In the shroud 45, the farther from the rotation center shaft 48 of the fan 16d, the higher the velocity of the air flowing by the fan 16d becomes.

Under such an air flow condition, since the oil cooler 54 is located in a place where the air flow velocity is high,
It will exhibit a great cooling capacity. Engine 1
For maintenance and inspection of 6, the engine room ER needs to be opened. In such a case, the positioning means j that fixes the upper wall portion 19a of the seat column 19 to the side column 25 is used. The seat column 19 is released from the positioned state by operating it. Thereafter, the seat column 19 and the outer side wall 39 are pivotally displaced outward about the front-rear axis 35 via the hinges 34, 34. As a result, the seat column 19 and the outer surface wall portion 32 are displaced independently of the radiator mounting frame 38 and the U-shaped support rod member 39, and the upper surface, front surface, and side surface of the engine room ER are largely opened.

FIG. 8 shows a modification of the above embodiment.
At this time, A is a view of the inside of the engine room ER as seen from the front,
B is the figure which looked at the engine room ER from the outer side of the outer side wall part 32.

In this modified example, the oil cooler 54 directly faces the air inlet b formed in the outer side wall 32 of the engine room ER and the ventilation range h of the radiator 42 fixed to the radiator mounting frame 38. It is arranged in the range k. At this time, it is preferable that the hydraulic oil in the ventilation range h1 of the oil cooler 54 flow vertically. Assuming that the oil cooler 54 does not exist,
When observing the air flow by the engine cooling fan 16d, the air inlet b of the outer side wall 32 and the radiator 42
Since the area k directly facing the ventilation range h is a location with less resistance to this air flow, the air flow velocity here is higher than the other ventilation range parts.

Under such a circumstance, the presence of the oil cooler 54 at the facing range point k means that the oil cooler 5 is present.
4 increases the cooling capacity of the radiator 42 and also contributes to the optimization of the cooling action of the radiator 42 by making the air flow velocity in the ventilation range h of the radiator 42 uniform.

Conventionally, an air flow guide plate m as shown by an imaginary line is provided in the facing area k to make the air flow velocity in the ventilation area h of the radiator uniform.
According to the present invention, the air flow guide plate m can be made uniform without the need.

Also, by fixing the wiring between parts in the engine room and the wiring that extends from the outside of the engine room to the inside of the side column along the U-shaped support rod member, it is possible to support these wires in an orderly manner. it can. Further, fixing the parts to the U-shaped support rod member can reduce the number of members for fixing the parts, and can reduce the trouble of assembling and disassembling around the engine.

According to the third aspect of the present invention, the parts related to the engine can be supported easily and conveniently via the U-shaped support rod member, and the wiring can be provided on the support rod member. Since the wiring is present above the engine when the is fixed, it is possible to effectively prevent the situation where the engine oil water falls onto the wiring.

According to the fourth aspect, the cooling capacity of the oil cooler can be improved by cooling the oil cooler by the air flow at a high speed.

According to the fifth aspect of the present invention, the air inlet formed in the outer side wall of the engine room and the ventilation range of the radiator fixed to the radiator mounting frame are located in the confronting range. Since the air flow is restricted by the oil cooler, it is possible to prevent the speed of the air flow from increasing in the facing area, which can improve the cooling capacity of the oil cooler and the ventilation range of the radiator. The cooling action of the radiator can be optimized by making the overall air flow velocity uniform.
