Thus, the vertical frame 58 is provided in front of the Glen tank 7, and the Glen tank 7 of the vertical frame 58 is provided.
Gear box 34 in front of the rear vertical frame 58 close to
Is provided, and the rotation transmitting members of the gear box 34 and the engine 48 are located on the front side of the rear vertical frame 58. Therefore, the front plate 59 of the Glen tank 7 has a minimum gap where the Glen tank 7 can rotate. And can be brought close to the rear vertical frame 58, thereby increasing the capacity of the Glen tank 7. Further, since the gear box 34 and the engine 48 are surrounded by the engine cover, the gear box 34 and the engine 48 are shut off from the Glen tank 7 side, and the intermediate wheel body 47, the endless belt 50, etc.
Prevent winding. Thus, the rotation transmission shaft member 33
Is provided substantially in parallel with the discharge spiral blade 9 of the Glen tank 7 and is positioned below the lower inclined surface 39 of the Glen tank 7 forming an angle of repose for flowing down grains. Needless to say, the upper portion is also surrounded by the lower inclined surface 39 of the Glen tank 7 at the time of the normal mowing and threshing operation, so that the adhesion of dust and the like is reduced.

And minimize the position change.

The rotation shaft 22 of the intermediate horizontal spiral blade 21
Since the input wheel 30 provided in the above and the intermediate wheel 31 fixed to the rotation transmission shaft member 33 are surrounded by the case 40, adhesion of dust, straw, etc. is prevented, and rotation transmission is reliably performed. I do. In addition, the case 40 is detachably fastened and fixed to the connection member 13 with bolts or the like, so that maintenance is facilitated. Further, the lower endless transmission belt 32 of the endless transmission belt 32 in the case 40 is formed in an arc shape by an elastic member, and one end is locked to the case 40 or the fixed portion on the connection member 13 side. Tension applying member 41
, The rotation transmission is ensured, and the transmission mechanism can be provided compactly.

Further, since the case 40 is provided on the front side of the vertical mounting shaft 42 serving as the center of rotation of the straw processing device 5 and the rotation fulcrum mounting frame 43 provided with the vertical mounting shaft 42, Even if the device 5 is rotated 90 degrees or more, there is no interference.

Further, since the gear box 34 is provided on the rear side of the engine 48, the overall length of the transmission path is shortened. That is, if the gear box 34 is provided on the front side of the engine 48, a transmission path must be provided on the front side from the output wheel body 49, and the overall length of the transmission path becomes longer, but this is prevented. The endless belt 50 between the output wheel 49 of the engine 48 and the intermediate wheel 47 of the gear box 34 is brought into contact with the tension clutch pulley 53.
The arm 54 has an inner 56 of a wire 55 for operation.
Of the wire 55 and one end of the outer 57 of the wire 55 is locked to the outer vertical frame 58 of the vertical frame 58 surrounding the engine 48. A pulley 53 is provided,
By locking the outer 57 to the vertical frame 58, the adjusting portion of the wire 55 (near the locking portion between the outer 57 and the vertical frame 58) is connected to the vertical frame 58 and the radiator 58 in side view.
The maintenance is facilitated even if the Glen tank 7 is not opened because it is located in the gap between "a" and "a".

The vertical frame 58 is located on the front side of the Glen tank 7, and the gear box 34 is provided on the front side of the rear vertical frame 58 near the Glen tank 7 in the vertical frame 58.
