When the operation of the unloader 6 is detected by this sensor, the electric fan 56 is You may comprise so that it may drive.

  The operation direction of the radiator fan 53 is set so as to always rotate in the direction in which the cooling air is sucked when the engine E is operated (see FIG. 5), and when the electric fan 56 is not driven, The upper cooling air sucked into the dustproof case 13 passes through the condenser 55 and the electric fan 56 and is supplied to the upper portion of the radiator 52. The lower cooling air sucked into the dustproof case 13 passes through the oil cooler 57 and is supplied to the lower portion of the radiator 52. As a result, the cooling air is supplied to the condenser 55, the oil cooler 57, and the radiator 52, and these can be cooled well.

When the discharge clutch lever 21 is operated to the engaged position and the unloader 6 is operated, this operation is detected by the discharge lever sensor 61 and the control device 62 operates the electric fan 56, whereby the intake air of the radiator fan 53 is detected. The air inside the dust-proof case 13 is sent to the outside of the aircraft against the air flow. For this reason, the air sent to the outside of the machine body passes through the condenser 55 and is sent out of the machine body from the dust screen 14, and dust such as straw attached to the outer surface of the dust network 14 is blown off by the wind pressure. 14 air flow is good.
Further, when the grain is discharged by the operation of the unloader 6, a large amount of dust is generated. Therefore, when the unloader 6 is operated, the electric fan 56 is continuously operated to generate the grain. It is possible to satisfactorily suppress the inconvenience that dust that adheres to the dust net 14.

  In particular, since the condenser 55 is arranged in parallel with the upper part outside the radiator 52, the inconvenience that the air heated by the condenser 55 is sent to the entire cooling surface of the radiator 52 is prevented. Further, since the air conditioner 29 is arranged at the upper part of the cabin C, the heat medium pipe 58 arranged between the air conditioner 29 and the condenser 55 is compared with the condenser 55 arranged at the lower part of the radiator 52. Shortening the length is also realized.

  Furthermore, in this combine, since the hydraulic equipment that sends oil to the oil cooler 57 is arranged below the traveling machine body 2, for example, the oil pipe is compared with the oil cooler 57 that is arranged above the radiator 52. A reduction in the length of 59 is also realized.
