Abstract

PURPOSE:To prevent the rise of temperature in an engine room by arranging a radiator in the rear part of an engine and forming a cooling air suction port on a bonnet on an operation part side in comparison with a radiator and arranging a cooling fan of front blow-out type in the front part of the engine. CONSTITUTION:A clutch 4 is connected to an operation part 3 side in the rear part of an engine 2 mounted onto a machine frame 1, and a radiator 5 is arranged in the upper part of the clutch 4. Further, a cooling water pump 6 is arranged in the front part of the engine 2. Further, on the front side of the engine 2, a partitioning wall 9 is erected from the machine body frame 1, and a fan shroud 10 is formed integrally onto the partitioning wall 9, and a cooling fan 11 of front blow-out type is arranged inside the fan shroud 11. By revolving the cooling fan 11 in the state where a bonnet 16 is closed, cooling air is sucked from the cooling air suction ports 20 opened in the upper surface part and the right and left side surface parts of an operation part 3 side in comparison with the radiator 5 in the bonnet 16.

Compared to a structure in which the radiator and cooling fan are placed at the front of the engine and cooling air is sucked in from the front of the bonnet,
The above-mentioned structure is preferable because the hot air from the radiator does not flow toward the driving section, but the cooling air that passes through the radiator from the side of the bonnet's driving section and enters the engine room becomes hot and enters the engine room. It was easy for the fuel to accumulate in the upper part of the engine room, causing the temperature inside the engine room to rise easily.

The feature of the present invention is that the engine cooling structure of the tractor is configured as follows. In other words, ■ A radiator is placed at the rear of the engine, a cooling air inlet is provided in the bonnet area closer to the driving section than the radiator, and a bulkhead with a fan shroud is installed at the front of the engine, and the fan shroud is installed at the front of the engine. A front-blowing type cooling fan is arranged inside the engine, and in addition to the above, an exhaust pipe is installed and connected between the muffler fixed to the engine and the upper part of the bulkhead. Its functions and effects are as follows.

When configured as in (2) above, outside air flows as cooling air from the cooling air intake port into the engine room through the radiator due to the suction action of the cooling fan. The cooling air flows near the engine and is discharged forward from the cooling fan. Further, since the fan shroud that enhances the suction effect of the cooling fan is provided on the partition wall that also enhances the suction effect, the support structure of the fan shroud, etc. can be simplified.

As described above, while maintaining the advantage that the hot air from the radiator does not flow toward the driving part, the cooling fan forcibly discharges the cooling air (hot air) from the radiator that may remain in the engine room. As a result, it is possible to suppress the temperature rise in the engine compartment, and the cooling air (hot air) from the radiator directly hits the engine body and attached layers and takes away heat, so the overall engine Cooling efficiency can be increased.
