[0047] tensioner arm 85 extends setting from discharging power shaft 31 1 sides at fore-and-aft direction, and is installed in and discharges at base end side on the columnar fulcrum shaft 87 of power shaft 31 concentric arrangement, can be around the direction rotation up and down of this fulcrum shaft.Fulcrum shaft 87 can be supported on the scaffold on the organism frame 2 freely rotatably, so that can be with respect to discharging power shaft 31 rotations.And tensioner arm 85 is connected with the discharge clutch switch 91 as operated from a distance mechanism on being arranged on running operation portion 15 through actuator, can be rotated by driving this actuator rotation.

[0048] actuator for example, as present embodiment, is made of motor 92, is configured in the top of discharging clutch 36, and is installed on the mount pad 93.This mount pad 93 is provided with in the mode of extending at fore-and-aft direction, and at the rear portion, between shelling portion 5 and tanker 8, is supported in rotationally from the organism frame 2 on the upright abutment wall that is provided with through fulcrum shaft 94.That is, front and back one side of mount pad 93 by hinged on organism frame 2.And, such as described later in the front portion of the installation motor 92 of mount pad 93, and extend the spring part 95 that is provided with from the top and be connected.In the front portion of this mount pad 93, dispose motor 92 with driving shaft 92a in the mode that the axis direction (left and right directions) identical with discharging power shaft extends, but arm 96 one are installed in rotatably on this driving shaft 92a.

[0049] and, between this motor 92 and discharge clutch 36, as bindiny mechanism, set the connecting rod 97 that for example constitutes in the mode of extending by bar or bar etc. at above-below direction, distolateral thereon connecting portion 97a is connected with the driving shaft 92a of motor 92 through arm 96, at the connecting portion 97b of its lower end side, sell with the middle part of the tensioner arm 85 of discharging clutch 36 and be connected.In addition, set the discharge clutch switch 91 above motor 92, this discharge clutch switch 91 and motor 92 are electrically connected by distribution etc.Discharge clutch switch 91 and constitute in conjunction with the fluctuation formula switch of side and clutch separation side etc., be configured in the running operation portion 15 by possessing clutch.In addition, the formation of actuator and discharge clutch switch is not special the qualification, and actuator also can be hydraulic cylinder or solenoid etc., and discharging clutch switch also can be press button etc.

[0050] in such structure, if discharge clutch switch 91 be carried out bulldozing operation to clutch in conjunction with side, then around rotation counterclockwise, connecting rod 97 is above arm 96 is pulled to the driving shaft 92a of motor 92 in Fig. 4.And, being moved upward by this connecting rod 97, tensioner arm 85 rotates upward, and idler roller 84 moves to the direction of pushing tightening belt 83.Thus, tightening belt 83 obtains tension force, becomes tensioning state, and discharging clutch 36 becomes bonding state, and power is passed to the discharge power shaft 31 of cereal grain-discharging device 30 from the output shaft 21 of engine 20.At this,, can adjust by spring part 95 by the tensioning situation of the tightening belt 83 of idler roller 84 tensionings.

[0051] opposite, be carried out bulldozing operation to the clutch separation side if discharge clutch switch 91, then the driving shaft 92a of motor 92 is rotating around clockwise direction in Fig. 4, and connecting rod 97 is pushed to the below through arm 96.And, moving downwards by this connecting rod 97, tensioner arm 85 rotates downwards, and idler roller 84 moves to the direction of leaving tightening belt 83.Thus, tightening belt 83 can not obtain tension force, becomes relaxed state, and discharging clutch 36 becomes released state, and power can not be delivered to the discharge power shaft 31 of cereal grain-discharging device 30 from the output shaft 21 of engine 20.Like this, discharge clutch switch 91 with CD-ROM drive motor 92, discharge the combination or the lock out operation of clutch 36, can cut off or connect from output shaft 21 to discharging the power that power shaft 31 transmits by operation.

[0052] and then, in combine 1, make and as described abovely be connected with motor 92 as actuator as the discharge clutch switch 91 of operated from a distance mechanism, by operating this discharge clutch switch 91, CD-ROM drive motor 92, carry out combination or lock out operation as the discharge clutch 36 of belt tension clutch, in this structure, sometimes can not discharge the combination or the lock out operation of clutch 36 because of the fault of electrical system or motor 92 itself etc., but with manual-operating mechanism via above-mentioned connecting rod 97, the bindiny mechanism of formation such as motor 97 itself and spring part 95 described later is connected on the discharge clutch 36, by operating this manual-operating mechanism, also can be manually to carry out the combination or the lock out operation of clutch 36.

[0053] promptly, as shown in Figure 4, will be arranged on the top of said motor 92, and, closely dispose with discharge clutch switch 91 in running operation portion 15 as the discharge clutch lever 101 of manual-operating mechanism.Discharge clutch lever 101 and be fixed on the fulcrum shaft 102 that direction is extended to the left and right at base end side, can be around (front and back) direction rotation up and down of this fulcrum shaft.The fulcrum shaft 102 of discharging clutch lever 101 can be supported on the support member 103 that is fixed on the organism frame 2 freely rotationally, but arm 104 one are installed on this fulcrum shaft 102 rotatably.

[0054] in addition, constitute in such a way: the mount pad 93 of motor 92 is installed, as previously discussed, with at the rear portion by fulcrum shaft 94 state that supporting rotationally of direction up and down, motor 92 is installed in preceding side lower part, possesses the fastener 93a that engages with spring part 95 at preceding upper lateral part.And, between the mount pad 93 and discharge clutch lever 101 of this motor 92, disposed spring part 95 in the mode of extending at above-below direction, it is connected with the fastener 93a of mount pad 93 in lower end side, and it is connected with fulcrum shaft 102 as the discharge clutch lever 101 of manual-operating mechanism through arm 104 in upper end side.At this, because manual-operating mechanism is connected on the end with the mount pad 93 of fulcrum shaft 94 opposite sides, so the operating physical force of discharging clutch lever 101 is lowered.

[0055] in such structure, if will discharge clutch lever 101 carries out rotating operation downwards, then spring part 95 is pulled to the top through arm 104, and mount pad 93 rotates integratedly upward with motor 92, and connecting rod 97 is pulled to the top through arm 96.And, being moved upward by this connecting rod 97, tensioner arm 85 rotates upward, and idler roller 84 moves to the direction of pushing tightening belt 83.Thus, tightening belt 83 obtains tension force, becomes tensioning state, and discharging clutch 36 becomes bonding state, and kinetic force is delivered to the discharge power shaft 31 of cereal grain-discharging device 30 from the output shaft 21 of engine 20.In addition, by the tensioning situation of the tightening belt 83 of idler roller 84 tensionings, can adjust by spring part 95.

[0056] opposite, if will discharge clutch lever 101 carries out rotating operation downwards, then spring part 95 is pushed to the below through arm 104, and mount pad 93 rotates downwards integratedly with motor 92, and connecting rod 97 is pushed to the below through arm 96.And, moving downwards by this connecting rod 97, tensioner arm 85 rotates downwards, and idler roller 84 moves to the direction of leaving tightening belt 83.Thus, tightening belt 83 can not obtain tension force, becomes relaxed state, and discharging clutch 36 becomes released state, and power can not be delivered to the discharge power shaft 31 of cereal grain-discharging device 30 from the output shaft 21 of engine 20.Like this, discharge clutch lever 101, can cut off or connect from output shaft 21 to discharging the power that power shaft 31 transmits with the combination or the lock out operation of manually discharging clutch 36 by operation.

[0057] like this, with can by operated from a distance mechanism or manual-operating mechanism carry out in conjunction with or the mode of lock out operation constituted discharge clutch 36.Therefore, in combine 1, for example at the combination or the lock out operation of discharging clutch 36 usually by operated from a distance mechanism, in the time of can not using operated from a distance mechanism because of fault of electrical system or actuator itself etc., can use manual-operating mechanism to discharge the combination of clutch 36 or the mode of lock out operation can separately be used operated from a distance mechanism and manual-operating mechanism.

[0058] promptly, because if barrier waits and can not use operated from a distance mechanism to discharge the combination or the lock out operation of clutch 36 for some reason, just can not discharge the grain in the tanker 8, so, not only can not promptly dry grain, tanker 8 can not be carried out inner maintenance rotationally to the side.Therefore, by near operated from a distance mechanism, disposing manual-operating mechanism in advance, can easily keep in repair etc. with simple structure.In addition, because discharging clutch lever 101 is non-common components, so do not utilize at ordinary times, therefore, as shown in Figure 9, set in advance trim 109 in the mode that covers rod guidance approaching channel 135a and be covered with, the position of the clutch separation above turning to keeps, and can unload trim 109 and operate when improper.
