Abstract: PURPOSE:To prevent such a possibility that dust or the like blown off in time of reversing a fan might flow into the side of a driver's seat from occurring by installing a means selecting the fan and a guide member guiding air out of the inner part of a bonnet in reversion of the fan to the ground side in the outside part of an intake part of the bonnet. CONSTITUTION:A fresh air passage C interconnecting an interspace between a dustproof net 20 and a radiator 8 in a bonnet 6 and the inner part of an upper bonnet 28 is formed by a partition plate 31. In addition, a guide member 35 being made up in a box from with a ceiling part at the machine body upper side, a longitudinal wall part and a plane part and, formed with an opening 35a at the machine body underside (ground side) is clamped to an outer part of the dustproof net 20 in the bonnet 6. With this constitution, in the reversion of a fan 9, dust or the like stuck to a surface of the radiator 8 and the dustproof net 20 of the bonnet 6 is blown away by a blowoff action of the fan 9. The dust or the like blown off is made so as not to flow into the side of a drive's seat owing to the guide member.

Abstract: PURPOSE:To improve cooling efficiency of a radiator by making a normally and reversely rotating state of a radiator fan alternately switchable and operable in an automatic manner, and constituting it so as to change the ratio of both states of normal and reverse rotations automatically according to a water temperature in a radiator. CONSTITUTION:When a first winding member 23 is in a normal rotation position A of a switching member 16 in case of a motor 24, power of a first driving belt 14 drives an input pulley 9a and a fan into normal rotation, taking in the outside air via a normal rotating pulley 17 and a second driving belt 19. In addition, when the first winding member 23 is rotated counterclockwise by the motor 24, and the switching member 16 is rockably operated to a reverse rotation position, the drive of the first driving belt 14 drives the input pulley 9a and the fan into reverse rotation via a reverse rotation pulley 18 and the second driving belt 19, thereby blowing off dust on a radiator surface or the like. In this connection, during both normal and reverse rotation positions, any power will in no case flow into the fan at all. When the selector member 16 is rockably operated to both normal and reverse rotation positions, or a difference between radiator water temperature and the setting temperature is large enough, by way of example, the setting time of the normal rotation position is set to be short but the setting time of the reverse rotation position is set to the side where it is lengthened.

Abstract: PURPOSE:To provide a grain culm transparting structure for preventing occurrence of unthreshed grain culm while suppressing increase in threshing operation load to the minimum limit by installing a whole culm throwing device, an extremely short culm detecting means and a threshing depth adjusting mechanism in the midst of a grain culm transporting passageway. CONSTITUTION:A whole culm throwing device 16 freely changeable from a transporting state for sending reaped grain culm to a state wherein holding of reaped grain culm at the foot side is released and the whole grain culm is thrown into a thresher 2 is installed in the midst of a grain culm transporting passageway for threshing treatment. An extremely short culm detecting means S3 for discovering so short length of transported grain culm that the grain culm can not be threshed is laid in the midst of a transporting passageway toward the thresher 2. A controlling means for changing the whole culm throwing device 16 from a holding and transporting state to a whole culm throwing state after elapse of a given transportation time of reaped grain culm moving from the set position of the extremely short culm detecting means S3 to the whole culm throwing device 16 when the extremely short culm detecting means S3 becomes a detecting state in a state of a threshing depth adjusted mechanism M1 controlled in the deepest threshing side is laid.
