As shown in figure 13, the 9th driver as group standing grain auger conveyor driving section of harvesting portion described later transmission mechanism Structure 126 is linkedly linked with auger conveyor by movable sprocket 35.That is, the 9th transmission mechanism 126 is by located at harvesting described later The auger conveyor drive sprocket 140 and auger conveyor of countershaft 125 is by wound coil conveyer driving-chain between movable sprocket 35 141 and formed.142 is the tension adjustment portion of the tensile force of adjustable screw conveyer driving-chain 141.According to harvesting countershaft 125 → Auger conveyor drive sprocket 140 → auger conveyor driving-chain, 141 → auger conveyor is by 35 → bolt of movable sprocket S2 → chain Wheel holds piece 34b → shaft hub 34a → extended portion 27a/ rotation 27 → auger conveyors of fulcrum main body 28 and transmits revolving force.

In addition, as shown in figure 13, the tenth transmission mechanism as winder driving section of harvesting portion described later transmission mechanism 150 and the 11st transmission mechanism 127 linkedly links with winder drive sprocket 36.That is, the tenth transmission mechanism 150 is by dialling Standing grain wheel driving movable sprocket 36 and the first winder are wound the first winder driving-chain 152 and are formed between movable sprocket 151.11st Transmission mechanism 127 by the second axially mounted on winder of movable sprocket 151 via the winder of relay axis 156 and first by being driven Second winder of movable sprocket 153 and the winder fulcrum 157 for being installed on winder 23 is wound second group between movable sprocket 154 Standing grain wheel driving-chain 155 and formed.Piece 34b → shaft hub 34a is held by 35 → bolt of movable sprocket S2 → sprocket wheel according to auger conveyor The winder of 36 → the first winder driving-chain of → extended portion 27a/ rotation 27 → winder of fulcrum drive sprockets 152 → the first By 151 → relay axis of movable sprocket, 156 → the second winder drive sprocket, 153 → the second winder driving-chain, 155 → the second groups of standing grain Wheel transmits revolving force by 157 → winder of movable sprocket 154 → winder fulcrum 23.

Now, for example, when excessive load (load) is acted on auger conveyor main body 28, sprocket wheel holds piece 34b and spiral shell Axis of the rotation conveyer by movable sprocket 35 around rotation fulcrum 27 carries out relative displacement, carries to linking both bolt S2 acting shears Lotus, but when the effect shear-type load exceed bolt S2 permission shearing force when, bolt S2 is cut off, sprocket wheel hold piece 34b and Auger conveyor is released by the link of movable sprocket 35.That is, when its boundary torque is exceeded to torque limiter T2 effects, (restriction turns Square) load when, torque limiter T2 play a role releasing transmission power.

Here, the boundary torque (torque-limiting) of torque limiter T2 by with the direction of the axis vertical take-off of bolt S2 on The product of the shearing force of effect and the distance from the center of rotation fulcrum 27 to the position for acting on the shearing force is tried to achieve, many being configured with It is their summation during individual bolt S2.In present embodiment, by allowing, shearing force and inner/outer circumference concentric circles C1, C2's is arbitrary The summation of the torque of each bolt S2 that the product of radius is tried to achieve is boundary torque (torque-limiting), than the boundary torque (torque-limiting) Big load is acted on when dialling standing grain auger conveyor 26 or winder 23, and the larger load is from group standing grain auger conveyor 26 or dials Standing grain wheel 23 to whole bolt S2 are transmitted, and are become shear-type load and acted on all of bolt S2, all of bolt S2 with Cut off in the direction of the axis vertical take-off.Then, torque limiter T2 plays its function, releases from engine 18 to group standing grain spiral transferring Send the transmission power of the rotary driving force of device 26 and winder 23.

In addition, the quantity by increasing or reducing bolt S2 of the ground regulating allocation on inner/outer circumference concentric circles C1, C2, energy Enough change the function of torque limiter T2.For example, by configuring multiple bolt S2 on the concentric circles C2 of periphery, increase boundary torque Greatly, on the other hand, by configuring a small amount of bolt S2 on inner circumferential concentric circles C1, boundary torque can be reduced.Additionally, by The position setting periphery concentric circles more outward more all than periphery concentric circles C2, configures bolt S2 on the periphery concentric circles, it is also possible to Increase boundary torque.
