When the door 16 is opened, the edge of the long hole 27a located on the free end side of the swing arm 27 comes into contact with the restriction pin 28, thereby restricting the swing of the door 16 in the opening direction. To do.

  The door frame 21 is made of metal having two grooves 21a and 21b integrally formed on the inner peripheral edge thereof, and is configured to support the door panel 22 by the grooves 21a and 21b.

  The door panel 22 is composed of two upper and lower panel bodies 22A and 22B, and flat glass is adopted for each of the panel bodies 22A and 22B.

  The upper panel body 22A is fitted into the outer groove 21a of the door frame 21 so as to be slidable in the vertical direction through a seal member 21A housed in the groove 21a. That is, the outer groove 21a in the door frame 21 is formed so as to function as a guide groove that supports the upper panel body 22A so as to be slidable in the vertical direction.

  The upper part of the upper panel body 22A can be opened and closed by sliding the upper panel body 22A from the inside of the cabin, and is engaged with a locked part 21B provided on the upper part of the door frame 21. An operating tool 29 that functions as a locking tool that enables the panel body 22A to be fixedly held in the closed position is provided.

  That is, in the cabin 9, the door 16 is provided with a slide-opening-type right side window 33, whereby, for example, a weed divider 34 positioned at the right end of the cutting and conveying device 3 is planted with a cocoon. When performing a harvesting operation at the time of being positioned appropriately between the cereals and a line-up operation for positioning the rightmost divider 34 at an appropriate position with respect to the planted culm, the upper panel body 22A is If the right side window 33 is fully opened by sliding operation downward, and the front side of the vehicle body is looked into from the fully opened right side window 33, the positional relationship of the divider 34 on the right end with respect to the planted cereals and straws Can be easily and accurately grasped, and this makes it possible to easily and efficiently perform harvesting work and alignment work at the shore.

  In addition, when the door 16 is provided with the sliding open / close-type right side window 33, the door frame 21 is also used as a sash, and the upper and lower panel bodies 22A and 22B are also used as a window panel. The number of points can be reduced, and accordingly, the weight of the vehicle body can be reduced, the productivity can be improved, and the cost can be reduced.

  The door frame 21 functions as a sash, so that the right side window 33 having a larger opening area can be provided as compared with a case where a sash is provided on the door panel 22, for example. In addition, since the notch 22a is formed in the upper panel body 22A facing the door handle 30, when the upper panel body 22A is opened, the lower end of the panel body 22A becomes the outer door. The handle 30 is displaced to enter between the door frame 21 and the outer door handle 30, thereby increasing the opening area in the maximum open state compared to the case where the notch 22 a is not formed. be able to. As a result, it is easier to look out from the right side window 33 to the outside of the vehicle, and the outside of the vehicle on the door side in a wider range can be easily seen from the right side window 33.

  In addition, since it is not necessary to provide a sash or the like at a position inside the door frame 21, the door frame 21, the door handles 30, 31 and the like are obstructed when the outside of the door is visually observed from inside the cabin. Moreover, most of the door frame 21 is superposed on the door receiving surface 14B of the cabin frame 14 and has a small adverse effect when the outside of the door side is visually observed from inside the cabin. As a result, the outside of the vehicle on the door side can be accurately observed in a wider range even from inside the cabin. As a result, for example, a truck in which the single-grained grains stored in the grain tank 6 are stopped at the shore When performing the grain discharging operation to be discharged to the cargo bed etc., it is possible to easily adjust the width of the straw.

  As shown in FIGS. 1, 2, and 5 to 9, the engine 11 is mounted on the vehicle body frame 1 in an anti-vibration manner with its output shaft 35 facing left and right, and a belt-type transmission on the right side. A cooling fan 37 that is rotationally driven in a certain direction by the power from the output shaft 35 that is transmitted via the mechanism 36 is provided, and the radiator 12 is erected on the right side of the cooling fan 37.

  The engine cover 10 is provided with an opening 38A for taking in outside air on the right side wall 38 facing the radiator 12, and is equipped with a dust net 39 for preventing inflow of dust from the opening 38A into the engine room.

  As shown in FIGS. 5 to 9, the transmission mechanism 36 includes an output pulley 40 that rotates integrally with the output shaft 35 of the engine 11, and a first input that rotates integrally with the input shaft 42 of the generator 41 disposed on the left side of the engine 11. The pulley 43, the second input pulley 46 that rotates integrally with the pump shaft 45 of the water pump 44 disposed in the front upper part of the engine 11, and a transmission belt 47 that is swung around the pulleys 40, 43, 46, etc. Has been.

  The cooling fan 37 can be slid in the direction along the longitudinal direction of the support pins 49 via the four support pins 49 to the rotating body 48 fixed to the pump shaft 45 together with the second input pulley 46. 7 wind generators equipped with a hook-shaped hub 50 and extending radially outward from the outer periphery of the hub 50 in conjunction with the sliding operation of the hub 50 so as to be possible. The rotating body 48 and each of the wind-up blades 51 are linked via a linkage member 52 so that the blades 51 are switched between the intake posture and the exhaust posture.

  In the intake posture of each of the wind blades 51, as the cooling fan 37 is driven to rotate, cooling air flowing from the dust screen side toward the engine side is generated, and clean outside air after dust removal by the dust screen 39 is used for cooling. To the engine 11 and the radiator 12.

  In the exhaust posture of each of the wind blades 51, as the cooling fan 37 is driven to rotate, a dust wind that flows from the engine side toward the dust net is generated, and the dust attached to the dust net 39 is blown out of the vehicle. Eliminated.

  In other words, the cooling fan 37 is driven by the sliding operation of the hub 50 to generate cooling air that flows from the dust-proof mesh side toward the engine side along with its rotation, and the exhaust that flows from the engine side toward the dust-proof mesh side. It is configured to be switched to an exhaust state that generates a dust wind.

  The operation of the operation mechanism 53 causes the hub 50 to be slid and operated between an intake position where each of the wind blades 51 switches to the intake posture and an exhaust position where each of the wind blades 51 switches to the exhaust posture.

  The operation mechanism 53 operates the electric motor 54 provided on the back surface of the engine cover 10 so that the hub 50 is slid between the intake position and the exhaust position by the operation of the electric motor 54 and the hub 50 via the bearing 55. The shift fork 56 attached thereto is operated and linked through a sector gear 57, a push-pull wire 58, and the like, and includes a push spring 59 that urges the hub 50 toward the intake position.

  As shown in FIG. 10, the operation of the electric motor 54 is controlled by a control device 60 configured with a microcomputer or the like.

  In the control device 60, the detection information of the threshing clutch sensor 61 that detects the operating state of the threshing clutch (not shown) that intermittently transmits power from the engine 11 to the threshing device 4, and the swing angle of the sector gear 57 are evoked. The detection information of the angle sensor 62 composed of a rotary potentiometer that is detected as the attitude angle of the blades 51, the detection information of the opening / closing sensor 63 that detects the opening / closing state of the entrance / exit 14A, and the like are input. A cooling state in which the operation state of the cooling fan 37 is switched to an appropriate state by controlling the operation of the electric motor 54 and switching and holding the attitude of each of the wind blades 51 based on detection information, a control program stored in advance, or the like. The switching control is executed as one of the control operations.

  The cooling state switching control will be described. The control device 60 always determines the operating state of the threshing clutch based on the detection information from the clutch sensor 61, and when the operating state of the threshing clutch is in the cut-off state, the threshing device. 1st cooling control suitable at the time of non-working, such as traveling traveling where 4 is not driven, and when the operation state of the threshing clutch is a connection state, the 2nd cooling control suitable at the time of work which drives threshing device 4 Execute.

  In the first cooling control, based on the detection information from the angle sensor 62, the operation of the electric motor 54 is controlled so that the attitude of each of the wind blades 51 is switched to the intake attitude, and the operating state of the threshing clutch is The operation state of the cooling fan 37 is maintained in the intake state until the connection state is switched.

  In other words, since clean outside air after dust removal by the dust screen 39 is always supplied to the engine 11 and the radiator 12 for cooling when the dust screen 39 is unlikely to be clogged, the efficiency is suitable for non-work. Good engine cooling.

  On the other hand, in the second cooling control, on the basis of the detection information from the angle sensor 62 and the count value of the built-in timer, first, during the first set time (for example, 3 minutes) set in advance, The operation of the electric motor 54 is controlled so that the posture is switched and held in the intake posture, and the intake state maintenance control for maintaining the operation state of the cooling fan 37 in the intake state is executed. After the first set time has elapsed, During the second preset time (for example, 10 seconds), the operation of the electric motor 54 is controlled so that the posture of each wind blade 51 is switched to the exhaust posture and the operation state of the cooling fan 37 is changed. Exhaust state maintenance control for maintaining the exhaust state is executed, and thereafter, intake state maintenance control and exhaust state maintenance control are executed alternately.

  In other words, when the dust-proof mesh 39 is easily clogged, clean outside air after dust removal by the dust-proof mesh 39 is supplied to the engine 11 and the radiator 12 for cooling while automatically cleaning the dust-proof mesh 39. Therefore, efficient engine cooling suitable for work that can avoid a decrease in cooling capacity due to clogging of the dust screen 39 can be performed.

  By the way, in the second cooling control, while the opening / closing state of the entrance / exit 14A is always monitored based on the detection information from the opening / closing sensor 63 and the closed state of the entrance / exit 14A is detected, as described above, the angle Based on the detection information from the sensor 62 and the count value of the timer, the intake state maintenance control and the exhaust state maintenance control are alternately executed. When the open state of the entrance / exit 14A is detected, the timer is reset and the entrance / exit 14A Until the closed state of the vehicle is detected, only the intake state maintenance control is executed. Then, the intake of the intake port 14A is detected based on the detection information from the angle sensor 62 and the count value of the timer. The state maintaining control and the exhaust state maintaining control are executed alternately in that order.

  That is, the control device 60 is configured to function as the restricting means 64 that restricts the operation of the cooling fan 37 so that the exhaust state of the cooling fan 37 does not appear as the opening state of the entrance / exit 14A is detected. As a result, the exhaust state of the cooling fan 37 appears when the entrance / exit 14A is open, so that the dust adhering to the dustproof net 39 is blown away by the exhaust air from the engine side. It is possible to avoid the inconvenience of inflowing into the cabin from the entrance / exit 14A in the open state, and as a result, a comfortable state in which dust blown off from the dustproof net 39 does not flow into the cabin. Can be maintained.

  Based on the detection of the open / close sensor 63, the control device 60 turns off the interior lamp 65 while detecting the closed state of the entrance / exit 14A, and controls the interior lamp 65 while detecting the open state of the entrance / exit 14A. The interior light blinking control for turning on is executed as one of the control operations.

  As shown in FIG. 2, the open / close sensor 63 is switched to an ON state by being pressed as the door 16 that opens and closes the entrance / exit 14A reaches the closed position, and as the opening operation from the closed position is performed. It consists of an on / off switch that switches to the off state when the pressing operation is released.
