Below, B describes to link mechanism.

As Fig. 1, Fig. 3, Figure 15 and shown in Figure 16, this link mechanism B is constructed as follows: the guide member 51 that will be formed with the slotted hole 50 of guiding usefulness is arranged on secondary shearing device 14 1 sides, the linked axis of guide that is directed part 52 of guiding of the conduct that can move freely along slotted hole 50 is arranged on harvesting conveyer 3 one sides, and, can remove the handover operation spare 53 that freely switches between the mode of operation in combined operation state that restricted guidance axle 52 moves along slotted hole and the interlock that allows the axis of guide 52 to move and be installed on the guiding piece 51 along slotted hole.

Specifically, shown in Fig. 2～4, the carrying case 11A across central elevator frame 13A among three elevator platform 13A, 13B, the 13C and connecting gear 11 is equipped with link gear B, and this link gear has the guide member 51 of the long chi shape on the above-below direction.As shown in Figure 6, the bottom of guide member 51 is installed on the handle fulcrum 54, and handle fulcrum 54 is fixed on the central elevator frame 13A.

As shown in Figure 3, guide member 51 is the slightly 51A of guiding function portion of コ shape with the section that is positioned at upside, and the connection support portion 51B that is positioned at the angle tubular of downside links into an integrated entity, as Figure 15 and shown in Figure 16, the 51A of guiding function portion is that the U-steel that section that the both sides by the 51a of wall portion of central authorities have side plate 51b, a 51b slightly is コ shape constitutes, and the 51a of wall portion of central authorities goes up the slotted hole 50 that forms along the vertical direction.

Leading section can be free to slide in the slotted hole 50 of guide member 51, is horizontally installed on the axis of guide that is directed part 52 on the traveling machine body, is fixed on the horizontal sidepiece of carrying case 11A.Outer being with on the leading section of this axis of guide 52 as the resin liner guide 56 that slips guiding piece, described resin liner guide 56 has a ring annular groove 55, is embedded in by the inner edge portion with the slotted hole 50 of guide member 51 in the annular groove of lining guide 56 and guides the axis of guide 52.

Guide member 51 has handover operation spare 53, can remove between the mode of operation in combined operation state that restricted guidance axle 52 moves along slotted hole 50 and the contact that allows the axis of guide 52 to move along slotted hole 50 freely to switch.Then, when handover operation spare 53 is switched to the contact mode of operation, handover operation spare 53 limit the axis of guides 52 the interlock on the slotted hole 50 be accompanied by with desired location P harvesting conveyer 3 on lift operations mobile, and in order to be switched at handover operation spare 53 under the state of combined operation state, allow the axis of guide 52 to move with position P to setting to contact from the state that the rising direction of operating to harvesting conveyer 3 moves, handover operation spare 53 can backboard change position and is returned to the combined operation state.

Supplementary notes, handover operation spare 53 is being supported by guide member 51, can remove between the mode of operation in combined operation state and interlock and freely swing, and the effect by spring 57 makes at combined operation state and interlock to be removed under the mode of operation and can both be maintained fixed because of elastic potential energy.

That is to say, as shown in figure 15, handover operation spare 53 is that bar is bent into slightly zigzag shape, top has manual operation unit 53a, the bottom has the qualification service portion 53b that acts on the axis of guide 52, manual operation unit 53a and limiting between the service portion 53b connects by relay 53c, is fixedly mounted in manual operation unit 53a and the carriage 58 that limits between the service portion 53b is supported on the fixed part 59 of guide member one side rotationally, makes the carriage 58 can be along the swing of body lateral shaft core X3 axle.Carriage 58 general curved become the L font, are provided with spring 57 between the end of swing one side of carriage 58 and the spring-loaded portion 60 on the guide member 51.

The manual operation unit 53a of described handover operation spare 53 is arranged on, and human pilot is stretched out one's hand manipulable locational at lift-launch Drive Section 6.

Manual operation handover operation spare 53, the words that surpass the clockwise direction swinging operation of dead point in Figure 15, just switched to combined operation state (state that the solid line among Figure 15 is represented), then the position (contact status of the corresponding link mechanism B of this state) of trying hard to keep and being held in the combined operation state by the elastic potential of spring 57.Manual operation surpasses the words of the counter clockwise direction swinging operation of dead point in Figure 15, remove mode of operation (state that the dotted line among Figure 15 is represented) with regard to having switched to interlock, then the position (the interlock disarm state of the corresponding link mechanism B of this state) of trying hard to keep and being held in interlock releasing mode of operation by the elastic potential of spring 57.

Handover operation spare 53, when the contact mode of operation, pass the through hole 61,61 of the last formation of side plate 51b, 51b of the both sides of guide member 51, the edge that touches the upside of through hole 61 is fixed, and is moved upward along slotted hole 50 thereby restriction is positioned at the axis of guide 52 of downside.Under this state, secondary shearing device 14 and harvesting conveyer 3 are linked together, make secondary shearing device 14 and then carrying case 11A liftings.

Handover operation spare 53 switches to the words that mode of operation is removed in interlock, lifting along with carrying case 11A, the axis of guide 52 can be free movable along the slotted hole 5 of guide member 51, secondary shearing device 14 just and the descending operation of carrying case 11A separate, lifting independently, secondary shearing device 14 and carrying case 11A are connected releasing.

According to this structure, such as, as shown in figure 18, the axis of guide 52 is when being positioned at the upper side of contact desired location P (state that (b) of Figure 18 shows), even mistakenly handover operation spare 53 is switched to combined operation state (state that (c) of Figure 18 shows), to gather in conveyer 3 puts down, secondary shearing device 14 ground connection,, the axis of guide 52 moves with respect to guide member 51, turns back to contact desired location P's, shown in Figure 18 (d), handover operation spare 53 is directed to axle and 52 pushes, backboard change position flexibly, and the axis of guide 52 turns back to interlock desired location P.The axis of guide 52 turns back to after the contact desired location P, because the elasticity of spring 57, switch piece 53 automatically restores to contact mode of operation (state that (e) of Figure 18 shows).

On the described guide member 51 limited part 62 is set, for limiting the rising mobile boundary of the axis of guide 52 along with harvesting conveyer 3, the installation site of limited part 62 on guide member 51 is to regulate along the long side direction of slotted hole 50.

By above-mentioned limited part is set, even handover operation spare 53 is switched to contact and removes mode of operation, if will gather in conveyer 3 is lifted to more than the setting height, mobile be limited of the axis of guide 52 in slotted hole 50, the axis of guide 52 and guide member 51 interlocks, secondary shearing device will rise along with the last lift operations of harvesting conveyer 3.

The result, handover operation spare 53 is switched to interlock remove mode of operation, the rising body makes the fringe end of 9 harvestings of main shearing device upright stalk stalk, and secondary shearing device 14 is set in lower position makes it cut off the stem end of upright stalk stalk, when gathering in operation like this, when carrying out steering operation,, the words that conveyer 3 is raised significantly will be gathered in even handover operation spare 53 is not switched to linkage status near ridge, secondary shearing device 14 also can and then rise, and avoids and the contacting of bottom surface.

Then, by adjusting the installation site of limited part 62 with respect to guide member 51 along the long side direction of slotted hole 50, limited part 62 begins effect, can readjust harvesting conveyer 3 to suitable relative lifting position according to the operation situation.

The bottom of guide member 51 is provided with 2 place's shaft sleeve part 64 of diverse location on the above-below direction, and handle fulcrum 54 is installed on the shaft sleeve part 64 with embedding, by change shaft sleeve part 64, can adjust the relative position of guide member 51 with respect to secondary shearing device 14.

Like this, also can pass through the position of the bottom of variation guide member 51, change the relative body lifting position of setting the harvesting conveyer 3 that limited part limited.

In addition, the bottom of the slotted hole 50 that on guide member 51, forms, be formed with when assembling 50a of big footpath hole portion for embedding usefulness that axle sleeve guide 56 is installed, even drop to greatest extent but will gather in conveyer 3, the axis of guide 52 can not move downwards from interlock desired location P, can not move to the 50a of big footpath hole portion.

When the harvesting operation, as shown in Figure 1, remove mode of operation by handover operation spare 53 being switched to interlock, make link gear B switch to the interlock disarm state.Then, when crossing the ridge walking, as shown in figure 19,, just the motor-driven B of contact can be switched to linkage status by handover operation spare 53 is switched to the combined operation state.

During operation, because link mechanism B has been switched to the interlock disarm state, secondary shearing device 14 is followed the limit lifting with the ground contact edge in harvesting, and the configuration height that is positioned at the rear of main shearing device 9 and main shearing device 9 is equal height roughly, does not gather in effect.

Then, when crossing the ridge walking, as shown in figure 19, for fear of with the contacting of ridge, will gather in conveyer 3 and raise significantly, make and rise to the non-job position that rises, if but link gear B were switched to linkage status, after harvesting conveyer 3 would be risen to the non-job position that rises, by the interlock effect of link gear B, secondary shearing device 14 contacts with ridge so can prevent secondary shearing device 14 because harvesting conveyer 3 is lifted.
