By this configuration, by about dial in carrying device 124A, 124B with harvested paddy stalk to the paddy stalk during by portion 127 conveyances, can prevent this paddy stalk cross in nearside divider 121C and moving.The result; cross the situation of middle nearside divider 121C compares with the paddy stalk; can make the dried side of strain of this paddy stalk be difficult to nearside divider 121C in the contact; thus; can avoid: the conveyance posture confusion that is caused the paddy stalk by this contact is a cause; by supplying with the neat variation of carrying device 125 with the fringe front side of paddy stalk when threshing apparatus 104 conveyances, it is residual that shelling takes place in the shelling of threshing apparatus 104 is handled easily, and promptly the grain rate of recovery is low.

In addition, as mentioned above, about dial in carrying device 124A, 124B, reaping part 103 is positioned under the state of operating area, these dial in transport mechanism 171A, the posture of 171B is that the center side on the left and right directions of reaping part 103 is offside in the inclination attitude at rear, and become the inclination attitude of lifting on the rear portion, in addition, these packers 172A, the posture of 172B is the inclination attitude of lifting on the rear portion, thus, reaping part 103 is positioned under the situation of operating area, for the middle nearside divider 121C that is flat-hand position or approximate horizontal posture, the closer to assistant's side of its conveyance direction, therefrom nearside divider 121C departs from upward more.Thus; can prevent by about dial in carrying device 124A, 124B to the paddy stalk is dialled in conveyance by portion 127 paddy stalk the paddy stalk by contact in the portion 127 in nearside divider 121C; as a result, can stop the confusion of the conveyance posture of the paddy stalk that causes with this contact is the grain rate of recovery low of cause.

Figure 24 is the approximate vertical view of the major part of expression 4 ridges harvesting job state, and Figure 25 is the approximate vertical view of the major part of expression 3 ridges harvesting job state.As Figure 12, Figure 13, Figure 24 and shown in Figure 25, the crawler belt 113A that is arranged in the left straw-distributing unit 121A of left-hand end (reaping part 103 away from Drive Section 102 sides about a side) of reaping part 103 and left side (away from a side of Drive Section 102) is configured so that the position consistency of left part 113Aa on the car body left and right directions of the crawler belt 113A in the careless top 121Aa of branch of left straw-distributing unit 121A and left side.In addition, under the state that the right part 113Ba that is arranged in the crawler belt 113B that the crawler belt 113B of the right straw-distributing unit 121B of 103 right-hand end (reaping part 103 Drive Sections 102 sides about a side) of reaping part and right side (Drive Section side) is configured so that on the right side protrudes to the outside, the car body right side a little from the careless top 121Ba of the branch of right straw-distributing unit 121B, the position of right part 113Ba on the car body left and right directions of the crawler belt 113B on careless top 121Ba of the branch of right straw-distributing unit 121B and right side is approximately consistent.

That is, about crawler belt 113A, 113B on left and right directions, separate given interval and dispose, make the tip spacing in their the cross-car outside can carry out maximum 4 ridges to gather in the operation width W of reaping part 103 of conveyance bigger than constituting from L.Thus, distance between the rut of crawler belt 113A, 113B about can increasing can not cause because of the elongated steering behaviour that causes of the ground contact length of each crawler belt 113A, 113B is low, can improve the performance wet Tanaka.

In addition, the crawler belt 113A in left side, consistent on left and right directions by the careless top 121Aa of position and the branch of left straw-distributing unit 121A that makes its left part 113Aa, the crawler belt 113A in left side can not divide careless top 121Aa to protrude to the car body left side from this.Thus, when the left-external side of body 101 exists the outside, the left and right sides of the periphery harvesting of standing crop Cx or body 101 to have the operation traveling of central authorities' harvesting etc. of standing crop Cx, Cy, crawler belt 113A on the left of can preventing presses to step on and is positioned at its left-external side standing crops Cx nearby, perhaps Zuo Ce crawler belt 113A splashes the generation of the first-class problem of its left-external side standing crops Cx nearby with mud, can avoid stepping on and spatter the low of operating efficiency that mud causes because of pressure.

On the other hand, the crawler belt 113B on right side, approximately consistent on left and right directions by the position that makes its right part 113Ba with the careless top 121Ba of the branch of right straw-distributing unit 121B, there is standing crop Cx in the outside, the left and right sides at body 101, when central authorities' harvesting of Cy waits the operation traveling, make the careless top 121Ba of branch of right straw-distributing unit 121B by the crop Cb in the operation width between the outer crop Cy of rightmost crop Cb in the operation width of reaping part 103 and the operation width adjacent if set with this crop Cb, the crawler belt 113B that can prevent the right side presses the generation step on the problem that is positioned at its right outside standing crops Cy nearby etc., can avoid stepping on the low of the operating efficiency that causes because of pressure.

In addition, the length L z that the careless top 121Ba of the branch from right straw-distributing unit 121B of the crawler belt 113B on right side protrudes to the outside, the car body right side, only being required to be the crawler belt 113B that can prevent the right side presses and to step on the length that is positioned at the outside, car body right side standing crops Cy nearby and get final product, for example, from with the plantation of the crop C relation of Sc at interval, can be set at all lengths such as Lz=1/3*Sc or Lz=1/4*Sc, but preferred Lz≤1/6*Sc.So it is short more that this protrudes length L z, the crawler belt 113B that can suppress the right side more splashes the outside, car body right side standing crops Cy nearby with mud, can prevent to spatter the low of operating efficiency that mud causes.On the contrary, it is long more that this protrudes length L z, and then crawler belt 113A in the left and right sides apart from long more, can improve the performance wet Tanaka between the rut of 113B.

That is, when the operation traveling of periphery harvesting or central authorities' harvesting etc., can constitute crawler belt 113A, 113B about can preventing stepped on or standing crops Cx, Cy are spattered comprehensive harvesting of mud to the pressure of standing crops Cx, Cy specification.

And the crawler belt 113B that also can dispose the right side makes that its right part 113Ba is consistent on left and right directions with the careless top 121Ba of the branch of right straw-distributing unit 121B, perhaps than the more close body inner side of the careless top 121Ba of the branch of right straw-distributing unit 121B.In addition, also can dispose the crawler belt 113A in left side, make its left part 113Aa than the more close body inner side of the careless top 121Aa of the branch of left straw-distributing unit 121A, and, crawler belt 113A on the left of can preventing presses to step on and is positioned at car body left-external side standing crops Cx nearby, and suppress in the scope of spattering mud to standing crops Cx, also can dispose and make its left part 113Aa than the more close car body left-external side of the careless top 121Aa of the branch of left straw-distributing unit 121A.

As shown in figure 24,3 nearside divider 121A～121C configurations make, when the operation traveling of harvesting 4 ridge culture thing C, the relative crop C of right straw-distributing unit 121B is adjusted the position, between crop Cy that the operation width on the right side that the interior rightmost crop Cb of the operation width that makes it divide careless top 121Ba to pass through reaping part 103 is adjacent with this crop Cb is outer or the harvesting track Cz of crop, under the situation on the side side of the crop Cb in the operation width, middle nearside divider 121C is by 2 ridge culture thing Cc of the medial side on the left and right directions in the operation width that becomes its effective object, the centre position of Cd or centre position roughly, and, in the operation width of left straw-distributing unit 121A by reaping part 103 between the harvesting track Cz of outer crop Cx of the operation width in leftmost crop Ca and the left side adjacent with this crop Ca or crop, position than the crop Ca in the more close operation width in their centre position.

Promptly, when the operation traveling of 4 ridges harvesting, will because of the front lower place that is positioned at Drive Section 102 make adjust the right cross side that the position makes its rightmost crop Cb by being positioned at the operation width from the careless top 121Ba of the branch of the high right straw-distributing unit 121B of Drive Section 102 visibilities near, thus for because of away from Drive Section 102 from the low left straw-distributing unit 121A of Drive Section 102 visibilities and nearside divider 121C, needn't carry out their Visual Confirmation, can pass through from the suitable position of the planting location that departs from crop C, can avoid these nearside dividers 121A, 121C pushes over or presses and step on crop C.

Thus, under the situation of the serious lodging of the C of crop, can be easily and reliably each nearside divider 121A～121B is adjusted the position to corresponding on the suitable position of crop C, can efficient carry out well each nearside divider 121A～121B and about the paddy stalk of raising apparatus 122A, 122B prop up.

In addition, because middle nearside divider 121C is by the centre position of 2 crop Cc, Cd of the center side on the left and right directions that is positioned at the operation width or centre position roughly, during the paddy stalk that therefore can make the paddy stalk of 2 ridge culture thing Ca, Cc in the framework of propping up framework 126A that imports to the left side and import 2 ridge culture thing Cb, Cd in the framework of propping up framework 126B on right side is located at nearside divider 121C directly over, across the paddy stalk by on the portion 127 symmetrical positions, can make becomes the paddy of its left and right sides object stalk and similarly shortens from the distance of paddy stalk by portion 127.

Thus, make about the paddy stalk of propping up the crop C that imports 2 ridges among framework 126A, the 126B respectively in, middle nearside divider 121C is away from the centre position of 2 crop Cc, Cd of the center side on the left and right directions that is positioned at the operation width, any paddy stalk of propping up among framework 126A, the 126B about can preventing to import is unnecessarily elongated from the distance of paddy stalk by portion 127, and any paddy stalk conveyance efficient of dialling in carrying device 124A, 124B of the left and right sides reduces.In addition; can prevent to produce unnecessary delay in any conveyance of the paddy stalk of dialling in carrying device 124A, 124B of the left and right sides; can prevent: owing to be the confusion of conveyance posture of the paddy stalk of cause with this delay; by supplying with the neat variation of carrying device 125 with the fringe front side of paddy stalk when threshing apparatus 104 conveyances; it is residual when the shelling of threshing apparatus 104 is handled shelling to take place easily, and promptly the grain rate of recovery is low.

And, since the left side of the leftmost crop Ca of left straw-distributing unit 121A by being positioned at the operation width laterally near, when the operation traveling of harvesting 4 ridge culture thing C, following needs are arranged all the time: careless top 121Ba carries out the position adjustment to the branch of right straw-distributing unit 121B, make its right side by being positioned at the rightmost crop Cb of operation width laterally near.

Thus, when the operation traveling of harvesting 4 ridge culture thing C, can make each nearside divider 121A～121C all the time, result, the raising of the operation during the operation traveling that can realize gathering in 4 ridge culture thing C reliably by with respect to the above-mentioned correct position of crop C.

As shown in figure 25,3 nearside divider 121A～121C configurations make, when the operation traveling of harvesting 3 ridge culture thing C, with the harvesting track Cz adjustment position of right straw-distributing unit 121B with respect to the crop on right side, make its divide careless top 121Ba by with the operation width of reaping part 103 under the situation of harvesting track Cz top of crop on the adjacent right side of rightmost crop Cb, in nearside divider 121C by than being positioned at the right side that becomes the operation of its effective object width and 2 crop Cb of the center side on the left and right directions, the position of the crop Cc of the center side on the more close left and right directions of crop Cb on the right side between the Cc, and, centre position in the operation width of the reaping part 103 of left straw-distributing unit 121A by becoming its effective object between the harvesting track Cz of outer crop Cx of the operation width in leftmost crop Ca and the left side adjacent or crop or centre position roughly with this crop Ca.

Promptly, when the operation traveling of 3 ridges harvesting, to make that adjusting the position from the careless top 121Ba of the branch of the high right straw-distributing unit 121B of the visibility of Drive Section makes it pass through the top of the harvesting track Cz on right side because of the front lower place that is positioned at Drive Section 102, thus for because of away from Drive Section 102 from the low left straw-distributing unit 121A of Drive Section 102 visibilities and nearside divider 121C, needn't carry out their Visual Confirmation, can pass through in the suitable position of the planting location that leaves crop C, can avoid these nearside dividers 121A, 121C pushes over or press and step on crop C.

Thus, even under the situation of the serious lodging of the C of crop, can be easily and reliably right straw-distributing unit 121B and middle nearside divider 121C are adjusted the position to for the suitable position of crop C, can efficient carry out well each nearside divider 121A～121B and about the propping up of paddy stalk of raising apparatus 122A, 122B.

In addition, since the right side of middle nearside divider 121C by the crop Cc of the center side on the left and right directions that is positioned at the operation width laterally near, therefore can make the paddy stalk of 2 ridge culture thing Ca, Cc in the framework of propping up framework 126A that imports to the left side and import to paddy stalk in the paddy stalk of 1 ridge culture thing Cb in the framework of propping up framework 126B on right side, that off normal directly over middle nearside divider 121C the shortest from the paddy stalk by the distance of portion 127 by the paddy stalk of the crop Ca in portion 127 left side farthest.

Thus, can cross raising by about dial in carrying device 124A, 124B with the conveyance efficient of 3 ridge paddy stalks when the paddy stalk is dialled in conveyance by portion 127.In addition; can prevent to produce unnecessary delay in any conveyance of the paddy stalk of dialling in carrying device 124A, 124B of the left and right sides; can prevent: owing to be the confusion of conveyance posture of the paddy stalk of cause with this delay; by supplying with the neat variation of carrying device 125 with the fringe front side of paddy stalk when threshing apparatus 104 conveyances; it is residual when the shelling of threshing apparatus 104 is handled shelling to take place easily, and promptly the grain rate of recovery is low.

In addition, because leftmost crop Ca and the centre position harvesting track Cz of the crop Cx operation width in left side outside or crop between or the roughly centre position of left straw-distributing unit 121A by in the operation width, when the operation traveling of harvesting 3 ridge culture thing C, can make from the minimum left straw-distributing unit 121A of Drive Section 102 visibilities be located in its sphere of action, on the planting location position farthest of the crop C of its effective object.

Thus, when the operation traveling of harvesting 3 ridge culture thing C, can make the crop C that acts on its effective object from the minimum left straw-distributing unit 121A of Drive Section 102 visibilities well, can prevent more reliably that left straw-distributing unit 121A is positioned on the planting location of crop C of effective object.

In addition, concrete configuration as 3 nearside divider 121A～121C of the position relation that is used to satisfy above-mentioned 3 nearside divider 121A～121C and crop C, 3 nearside divider 121A～121C between left and right every the plantation of Sa, Sb and the crop C relation between the Sc at interval, can be thought of as Sa=Sb=1.75*Sc configuration, Configuration, perhaps under Sa＞Sb And

Configuration, perhaps Sa is less than under the Sb

And

Configuration etc.And, when the operation traveling of harvesting 4 ridge culture thing C, the spacing distance La that preferably makes left straw-distributing unit 121A and the leftmost crop Ca that is positioned at the horizontal operation width in its right side is greater than the spacing distance Lb of right straw-distributing unit 121A with the rightmost crop Cb that is positioned at operation width horizontal on the left of it.

As Figure 12,13 and shown in Figure 17, about nearside divider 121A, 121B constitute and to make their posture of the careless tool 151A of branch, 151B be inclination attitude the closer to the offside body inner side in the car body left and right directions of rear vehicle side.Thus, can make the easier central authorities on the left and right directions of operation width of crop Ca, Cb at both ends, the left and right sides of the operation width that is positioned at reaping part 103 close.

As Figure 10～Figure 13 and Figure 15～shown in Figure 180, be equipped with on the leading section of the left and right directions of reaping part 103 and parted careless bar 199A on the left side, parted careless bar 199B on the right side and be arranged in the careless bar 199C of branch that this parts careless bar 199A on the left side and parts the central authorities on the left and right directions of careless bar 199B on the right side.

As Figure 10, Figure 12, Figure 13 and shown in Figure 15, part the left side that careless bar 199A is equipped in reaping part 103 on the left side, make it by shaking, the effect posture that can tilt in the left foreign side mode of stretching out to body 101 and be retracted into the body side erect take in and carry out the posture conversion between the posture.And, switch to the effect posture by parting careless bar 199A on the left side, can stop the lodging of the standing crops Cx of the left-external side that is present in body 101 to the body inner side direction.

Figure 26 parts the stereogram of major part of mounting structure of the careless terminal part side of branch of careless bar 199A on the left side for expression.As Figure 10, Figure 12, Figure 13, Figure 15 and shown in Figure 26, part careless bar 199A on the left side and divide the careless top 199a of portion can joltily be linked to it to part on the left side on the careless tool 151A by the 1st linking part 200.In addition, will divide stretching out end 201a and can joltily being linked on the support component 136 of reaping part 103 of connecting rod 201 that careless terminal part side stretches out from this by the 2nd linking part 202.

The 1st linking part 200 constitutes by being welded in the connecting pin 204 that L font carriage 203 that parts on the left side on the careless tool 151A and the careless top 199a of portion of the branch that will part careless bar 199A on the left side can joltily be linked on this carriage 203, and makes connecting pin 204 approach to part on the left side the left side of careless tool 151A.

The 2nd linking part 202 is by the carriage 205 that is welded in support component 136, constitute the maintaining body 207 that end 201a can joltily be linked to the connecting pin 206 on this carriage 205 and can keep parting on the left side the posture of careless bar 199A that stretches out of connecting rod 201.And, effectively utilize the space that exists on the position, dead astern of propping up the left end on the framework 126A in left side, configuration makes and to be positioned at than the center side on the left and right directions of the 1st linking part 200 more close reaping parts 103, and than the center side on the left and right directions of the more close body 101 of left part 113Aa of the crawler belt 113A in left side.

Maintaining body 207 constitutes, formed on carriage 205 with connecting pin 206 is the circular-arc slotted hole 205a at center, after bolt 208 was inserted this slotted hole 205a, the embedding compression spring 209 outside the top side of inserting at this bolt 208, screw togather a pair of nut 210, under the effect of compression spring 209, stretch out end 201a and carriage 205 by crimping connecting rod 201, allow part the effect posture of careless bar 199A on the left side along slotted hole 205a and take between the posture shake operation in, the posture that parts careless bar 199A on the left side keeps.

By above-mentioned structure, even the 2nd linking part 202 is constituted in the large-scale mode that has been equipped with maintaining body 207, switch to when taking in posture in the posture that parts careless bar 199A on the left side, when the left part that makes reaping part 103 is positioned at the operation traveling of the crop C on limit, the ridge being gathered in limit, the ridge etc. under the situation, can avoids other object such as the 2nd linking part contact ridge and be out of shape.This is being formed in the field of lower ridge by concrete block etc., prevent because of contacting aspect the distortion that this concrete block causes the 2nd linking part 202 especially effective.

In addition, the axle center P that shakes that parts careless bar 199A on the left side at the center of the connecting pin 204 by the 1st linking part 200 and the connecting pin 206 of the 2nd linking part 202 is inclination attitude the closer to the offside center side on the left and right directions of reaping part 103 of the rear portion side of reaping part 103, therefore be set at along the posture of the fore-and-aft direction of reaping part 103 and compare with the axle center P that shakes that will part careless bar 199A on the left side, can reduce to improve the operability that parts careless bar 199A on the left side with parting careless bar 199A on the left side taking in posture and the effect operation angle when shaking operation between the posture.

Figure 27 shows to part the vertical view that careless bar 199A switches to the major part of the state of taking in posture on the left side.As Figure 13 and shown in Figure 27, parting careless bar 199A on the left side constitutes, take in the posture at it, divide careless terminal part 199b to be positioned under the state than the center side on the left and right directions of the more close body 101 of the left end side of reaping part 103 at it, it divides the position of left end side on the car body left and right directions of careless terminal part 199b and reaping part 103 approximately consistent.

Thus, part careless bar 199A on the left side, take in the posture at it, divide careless terminal part 199b to be positioned under the state than the center side on the left and right directions of the more close body 101 of left part 113Aa of the crawler belt 113A in left side at it, it divides the position of left part 113Aa on the car body left and right directions of crawler belt 113A in careless terminal part 199b and left side approximately consistent.

Promptly, switch to and take in posture by parting careless bar 199A on the left side, the careless terminal part 199b of the branch that parts careless bar 199A on the left side is positioned at than the center side on the left and right directions of the more close body 101 of left part 113Aa of the crawler belt 113A in the left-hand end of reaping part 103 and left side, thus, can make the integral body that parts careless bar 199A on the left side the body inner side than the more close car body left and right directions of left-external side end of seizing transport mechanism 131 on both sides by the arms, wherein this seizes transport mechanism 131 on both sides by the arms than the more close car body left-external side of the left part 113Aa of the crawler belt 113A in left side.The result, seize the situation of the more close car body of the left-external side end left side foreign side of carrying device 131 on both sides by the arms compares with the careless terminal part 199b of the branch that parts careless bar 199A on the left side geometric ratio, can diminish parting the left and right sides width that careless bar 199A switches to the integral body of taking in the combine under the posture state on the left side, can improve taking in property garage etc.

Part careless bar 199A formation on the left side and make that under it takes in posture it divides careless terminal part 199b than the paddy stalk conveyance path 188 more close car body upper sides of supplying with carrying device 125.Thus, even switch under the state of taking in posture will parting careless bar 199A on the left side, can by supply with carrying device 125 with the paddy stalk under the situation that does not contact the careless terminal part 199b of the branch that parts careless bar 199A on the left side to threshing apparatus 104 conveyances.

That is,, can avoid parting on the left side the careless terminal part 199b of branch of careless bar 199A by the paddy stalk contact of supplying with 125 conveyances of carrying device even switch to and carry out the operation traveling under the state of taking in posture will parting careless bar 199A on the left side.As a result, can avoid: the neat variation of the fringe front side that causes owing to the confusion of conveyance posture that with this contact is the paddy stalk of cause, it is residual when the shelling of threshing apparatus 104 is handled shelling to take place easily, and promptly the grain rate of recovery is low.

And, switch under the state of taking in posture will parting careless bar 199A on the left side, owing to part the integral body of careless bar 199A on the left side than the body inner side direction on the more close car body left and right directions of the left-external side end of seizing carrying device 131 on both sides by the arms of threshing apparatus 104, therefore carry out on limit, the ridge under the situation such as operation traveling, can make under the state of the more close ridge of car body and carry out the operation traveling, the easier position adjustment of carrying out left straw-distributing unit 121A to the crop C on limit, the ridge.As a result, can improve operation on limit, the ridge.

In addition; crop C for the short stalk that stalk length is about 65～75cm, the worry of lodging is less; switch to and take in posture and make that part careless bar 199A on the left side does not act on its fringe end by parting careless bar 199A on the left side; can avoid making grain break away from the paddy stalk to careless the acting on of the branch of the paddy stalk of crop C because of parting careless bar 199A on the left side; as a result, can improve the grain organic efficiency.This is particularly effective when the long-grained nonglutinous rice etc. of the easy threshing of harvesting.

As Figure 10～Figure 13 and Figure 15～shown in Figure 17, the careless bar 199C of middle branch is in the leading section of reaping part 103C, during being arranged on, setting divide careless tool 151C to linking between the parts 167 centre position on the roughly left and right directions of raising apparatus 122A, 122B about being located at.

Thus, thereby by about guidance field Aa1, the Ab1 of each raising apparatus 122A, 122B in the effect of dialling in of respectively propping up pawl 159A, 159B and to the paddy stalk of raising apparatus 122A, the 122B of the another side lodging crop C that positive visual angle becomes to report to the leadship after accomplishing a task from car body on car body the place ahead of the regional Aa1 of propping up of each raising apparatus 122A, 122B, Ab1 by the branch grass effect of the careless bar 199C of branch, separate to the left and right towards prop up regional Aa1, the Ab1 of pairing raising apparatus 122A, 122B.

The result, the paddy stalk that can avoid the crop C that gathered in is because of the effect of dialling in of respectively propping up pawl 159A, 159B among guidance field Aa1, the Ab1 of each raising apparatus 122A, 122B intersects from the positive visual angle of car body and entwines at the car body front side of the regional Aa1 of propping up of each raising apparatus 122A, 122B, Ab1, can prevent propping up under the efficient or propping up bad generation of its crop paddy stalk of causing of entwining.

As Figure 12, Figure 13, Figure 17, Figure 21 and shown in Figure 22, constitute with raising apparatus 122B on 2 ridges that propping up of right side is equipped with on the framework 126B and to make it prop up regional Aa2 to be positioned at left side away from Drive Section 102.

Thus, having equipped to prop up that regional Ab2 is positioned on the framework 126B with propping up of right side is that 2 ridges that the mode on right side of Drive Section side constitutes are compared with the situation of raising apparatus, can make from the sight line in 102 pairs of car body the place aheads of Drive Section better, the visibility that can improve from the operation in 102 pairs of car body the place aheads of Drive Section ground etc.

About raising apparatus 122A, 122B so that their left and right sides width W a, the Wb that prop up regional Aa2, Ab2 form corresponding to the mode of the width of propping up of the paddy stalk on maximum 2 ridges.Prop up pawl 159A, the 159B of the last outfit of raising apparatus 122A, the 122B in addition, have formed the length that corresponding broad is propped up regional Aa2, Ab2.

Thus, when raising apparatus 122A, the 122B about carrying out props up the operation traveling of 4 ridges harvestings of paddy stalk on 2 ridges all the time respectively, can prevent the paddy stalk by about corresponding resistance when propping up regional Aa2, Ab2 surpass permissible range.As a result, when the operation traveling of carrying out 4 ridges harvestings, can be smoothly and the paddy stalk that carries out left and right sides raising apparatus 122A, 122B well prop up.

In addition, respectively prop up pawl 159A, 159B and formed the length that corresponding broad is propped up regional Aa2, Ab2, can prevent from the regional Aa2 of propping up of broad, Ab2, to form and prop up the dead band that pawl 159A, 159B do not act on the paddy stalk owing to make.As a result, respectively prop up regional Aa2, the Ab2 of raising apparatus 122A, the 122B about making have formed when allowing the width that 2 ridge paddy stalks pass through raising apparatus 122A, 122B the propping up the paddy stalk about can carrying out reliably.

And, no matter when being the operation traveling of gathering in or when the operation traveling of 4 ridges harvesting on 3 ridges, only make its left and right sides width W a that props up regional Aa2 of raising apparatus 122A in the left side of having supplied with 2 ridge paddy stalks all the time form the width of propping up of corresponding maximum 2 ridge paddy stalks, and it props up the length of propping up regional Aa2 that pawl 159A can constitute corresponding broad.

As Figure 11, Figure 14 and Figure 16～shown in Figure 180, the right part that cutter drive unit 170 is disposed at intermediate member 135 makes the right-hand end that is positioned at reaping part 103.Thus, can prevent with cutter drive unit 170 be provided to the harvested paddy stalk that is caused under the situation of the center side on the left and right directions of reaping part 103 be wound in the undesirable of cutter drive unit 170 and cutter drive unit 170 is provided to cause under the situation of left-hand end of reaping part 103 only have the operation traveling of the higher periphery harvesting of the operation frequency of standing crop Cx in the left foreign side of body 101 time this standing crops Cx be wrapped in undesirable on the cutter drive unit 170.

In addition, supply with carrying device 125 and be disposed on the position that keeps left on the reaping part 103 and make that dialling in conveyance supplies with conveyances by the paddy stalk of portion 127 to the threshing apparatus 104 in car body left side to the paddy stalk because of making, the cutter drive unit 170 that weight ratio is bigger is provided to the right-hand end of the heavier reaping part 103 in left side, can improve the left and right sides balance of reaping part 103.

Disposed the lid 211 that covers the metallic plate system of cutter drive unit 170 on the right-hand end of reaping part 103.Lid 211 utilizes two bolts 212 that right straw-distributing unit 121B are attached to the upside among 3 bolts 212 of right part of intermediate member 135, and parts the right part that careless bar 199B is attached to intermediate member 135 jointly on the right side.

Thus, when having the operation traveling of central authorities' harvesting of standing crops Cy in the right outer side of body 101,, can avoid the right lateral standing crops Cy of this car body to be wound on the cutter drive unit 170 owing to part careless bar 199B on the right side and cover 211.

In addition, with bolt with right straw-distributing unit 121B, part careless bar 199B on the right side and compare with 211 situations that are linked to the right part of intermediate member 135 respectively of covering, can improve assembleability.And, part on the right side under the situation of the careless bar 199B and the replacing of lid 211, can prevent that right straw-distributing unit 121B from carrying out their replacing when the right part of middle parts 135 is unloaded fully.

As Figure 11～shown in Figure 13, be positioned at the body side frame 213 of the anterior right-hand end of body 101, its first half tilts to the car body left and right directions, makes the closer to front more near the right part 113Ba of the crawler belt 113B on right side.Thus, when also having the operation traveling that the central authorities of standing crops Cy gather in the right outer side of body 101, the lateral surface 213a of body side frame 213 is played as guide surface the standing crops Cy of side outside the car body right side is directed to the right lateral effect of car body.As a result, can with minute careless bar 199B together, stop to be present in the lodging of the right lateral standing crops Cy of body 101 to body inner side.

And, about dial among carrying device 124A, the 124B, about dial in transport mechanism 171A, 171B dialling under the situation of paddy stalk before conveyance acts on harvesting dialled in that belt 174a, 174b carry out the paddy stalk by rubber system, the protuberance 174a, the 174b that dial in belt 174a, 174b are out of shape because of the intensity of the paddy stalk before gathering in, by this distortion, before this paddy stalk of harvesting, this paddy stalk can not dialled in conveyance to the paddy stalk by portion 127.In addition, by the operation traveling of this moment, the paddy stalk before the harvesting is bent to car body the place ahead.

Therefore, when the harvested position of the paddy stalk arrival reaping apparatus 123 that so bends and quilt harvesting, in harvesting, sometimes getting back under the reactivation of straight condition to the state in car body the place ahead from bending, to away from about the car body front side of dialling in transport mechanism 171A, 171B jump out, the conveyance zone of dialling in transport mechanism 171A, 171B about leaving is scattering into the place ahead of reaping apparatus 12.

If such phenomenon takes place, the paddy stalk that is scattering into the place ahead of reaping apparatus 12 is accompanied by the operation traveling and to the left and right the conveyance zone of dialling in transport mechanism 171A, 171B imports successively follow-up does not receive harvested cereal culm by the harvested position of getting back to reaping apparatus 12, and side is done in its strain and the paddy stalk that do not gather in is gathered in together once more.

If the secondary harvesting of such paddy stalk takes place; then the bar length of paddy stalk becomes not neat; not neat by this is cause; neat variation in the fringe front side during to threshing apparatus 104 conveyances with the paddy stalk; so; it is residual when the shelling of threshing apparatus 104 is handled shelling to take place easily, and the result causes the low of grain organic efficiency easily.

So, as Figure 17, Figure 18, Figure 22 and shown in Figure 23, in this combine, about making dial among carrying device 124A, the 124B about dial in straight line conveyance path 214A, 214B that transport mechanism 171A, 171B constitute them with respect to car body fore-and-aft direction, identical to tiltangle a, the θ b of car body left and right directions.In addition, the posture of dialling in transport mechanism 171A, 171B and supply carrying device 125 about setting makes the straight line conveyance path 214A that dials in transport mechanism 171A in left side and the angle theta A between the straight line conveyance path 214B that dials in transport mechanism 171B on right side greater than the angle theta B between the dried straight line conveyance path 215 of seizing carrying device 182 on both sides by the arms of the straight line conveyance path 214A that dials in transport mechanism 171A in left side and the strain in the supply carrying device 125.

The posture of dialling in transport mechanism 171A, 171B about setting if so, but then its linearity ground on left and right directions is arranged continuously, but can be made the harvested position of each moving knife 168 that straight line conveyance path 214A, 214B arrange with respect to linearity on left and right directions and dead knife 169 and be positioned at roughly state along harvested position by a plurality of moving knife 168 of alignment arrangements above reaping apparatus 123 and dead knife 169.

Thus; dial in carrying device 124A, 124B about can suppressing effectively act on paddy stalk before the harvesting by reaping apparatus 123, can suppress effectively because of about dial in carrying device 124A, 124B act on the low of the grain organic efficiency that causes of paddy stalk before the harvesting.

In addition, can make the paddy stalk that just gathered in by reaping apparatus 123 by about dial in carrying device 124A, 124B promptly dial in conveyance by portion 127 to the paddy stalk, as a result, dial in carrying device 124A, the 124B about can improving dials in conveyance efficient to the paddy stalk.

As Figure 17 and shown in Figure 22, about dial among carrying device 124A, the 124B straight line guide portion 173A, the 173B that extend at the pivot that has been equipped with packer 172A, the 172B of end to about correspondence from about the reaping part 103 on guide member 173A, the 173B.Each straight line guide portion 173A, 173B form the horizontal linearity of vertical car body fore-and-aft direction.

Thus, about straight line guide portion 173A, the 173B of guide member 173A, 173B when the operation traveling, act on the paddy stalk before the harvesting, can prevent that this paddy stalk is bent to car body the place ahead.As a result, the paddy stalk that can avoid this press-bending becomes scattered about the place ahead of reaping apparatus 12 by the reactivation from the press-bending state and is gathered in by secondary when harvesting.

As Figure 12 and shown in Figure 23, supply with carrying device 125 and set its conveyance posture from the mode that the positive visual angle of car body overlaps with Drive Section 102 with the conveyance top 125b of portion.Thus, constitute reaping part 103 by specification with the harvesting of 2 frameworks, 4 ridges, make the position consistency of left part 113Aa on the car body left and right directions of crawler belt 113A in the careless top 121Aa of branch of left straw-distributing unit 121A and left side, and the position of right part 113Ba on the car body left and right directions of the crawler belt 113B on careless top 121Ba of the branch of right straw-distributing unit 121B and right side is roughly consistent, then the paddy stalk with respect to the pars intermedia on the left and right directions that is positioned at car body 101 passes through portion 127, the conveyance top 125b of portion that supplies with carrying device 125 is positioned at can directly receives by on the position of paddy stalk by the dead astern of portion 127 of paddy stalk by the paddy stalk after the portion 127.

That is, can access about dial between carrying device 124A, 124B and the supply carrying device 125 not the supply conveyance structure auxiliary carrying device, that be suitable for the reaping part 103 that constitutes with 2 frameworks, 4 ridges harvesting specification of the handing-over of paddy stalk being carried out transfer.

Drive Section 102 forms the recess 102a that the conveyance top 125b of portion of permissible feed carrying device 125 enters on the leading section of the side plate 115 that overlaps with the conveyance top 125b of portion that supplies with carrying device 125 in the positive visual angle of car body.

Supply with carrying device 125 and increase with respect to the dried straight line conveyance path 215 of seizing transport mechanism 182 on both sides by the arms of the strain of car body fore-and-aft direction and end the tiltangle d of the straight line conveyance path 216 of transport mechanism 183, make the recess 102a that the conveyance top 125b of portion is entered Drive Section 102 to the car body left and right directions to the tiltangle c of car body left and right directions with respect to the fringe end card of car body fore-and-aft direction.

Thus, compare with the situation that does not form recess 102a on the Drive Section 102, can make the nearly Drive Section 102 of conveyance top portion side joint of supplying with carrying device 125, can shorten the length on the car body fore-and-aft direction of supplying with carrying device 125 thus, can shorten the total length of combine.

In addition, along with the more close Drive Section 102 of conveyance top side of supplying with carrying device 125, thus, the also more close Drive Section 102 of action bars 198 that the processing depth adjustment that is equipped with on the support frame 190 of supply carrying device 125 is used, as a result, can carry out easilier handling the operation of the action bars 198 that depth adjustment uses from Drive Section 102.

And,, then supply with carrying device 125 and dial in transport mechanism 171A near left sides if increase to supply with carrying device 125 with respect to tiltangle c, the θ d of car body fore-and-aft direction to the car body left and right directions.Therefore, dial in transport mechanism 171A, cause the conveyance posture confusion of paddy stalk by what the side contacts left side was done in the strain of the paddy stalk of supplying with carrying device 125 conveyances.

Therefore, as Figure 10, Figure 11, Figure 14～Figure 16 and shown in Figure 180, in this combine, with the height and position of dialling in transport mechanism 171A in left side be configured to than the right side to dial in transport mechanism 171B lower.Thus; can prevent to cause the conveyance posture confusion of its paddy stalk by the dialling in transport mechanism 171A of the dried side contacts of the strain of the paddy stalk of supplying with carrying device 125 conveyances left side; can prevent: by this confusion is cause; by supplying with the neat variation of carrying device 125 with the fringe front side of paddy stalk when threshing apparatus 104 conveyances; it is residual when the shelling of threshing apparatus 104 is handled shelling to take place easily, and promptly the grain organic efficiency is low.

In addition, if the transport mechanism 171A that dials in left side constitutes 2 ridges usefulness, and increase to supply with carrying device 125 with respect to tiltangle c, the θ d of car body fore-and-aft direction to the car body left and right directions, then the left side props up paddy stalk the dialling in transport mechanism 171A and supplying with carrying device 125 with roughly U font conveyance by the left side that framework 126A is gathered in.Therefore, roughly the paddy stalk in the switching place of the conveyance direction of the paddy stalk of U font conveyance is by in the portion 127 becoming this, and side is done in the strain of this paddy stalk the tendency of significantly shaking because of centrifugal force.

Therefore, as Figure 10, Figure 11, Figure 15～Figure 19 and shown in Figure 22, in this combine, the linking part 135A of fore-and-aft direction has been installed between extended part 134 and intermediate member 135, by extended part 134 is departed to the car body rear side by portion 127 from the paddy stalk, between extended part 134 and intermediate member 135, formed can allow from about the strain that carrying device 124A, 124B transfer to the paddy stalk of supplying with carrying device 125 of dialling in do side transferring path 217 that pass through, that the front and back width is bigger.

Thus; pass through in the portion at the paddy stalk; even the strain of paddy stalk is done side and is significantly shaken because of centrifugal force; also can prevent the external part of the dried side contacts extended part 134 of strain of this paddy stalk; can prevent the confusion of conveyance posture of the paddy stalk that brings by this contact and the neat variation of the fringe front side of the paddy stalk that causes; it is residual that shelling takes place in the shelling of threshing apparatus 104 is handled easily, and promptly the grain rate of recovery is low.

In addition, configuration extended part 134 is located at than the left end side of paddy stalk by portion's 127 more close reaping parts 103.Thus, by in the portion 127, can prevent more reliably that the strain of the paddy stalk that significantly shakes because of centrifugal force from doing the external part of side contacts extended part 134, can prevent the low of the grain rate of recovery that causes because of this contact more reliably at the paddy stalk.

Further, the guide member 173A, the 173B that dial in carrying device 124A, 124B about formation makes that will do side direction by the strain of the paddy stalk of portion 127 by the paddy stalk supplies with carrying device 125 guiding, and, the 73c of guiding terminal portion of the guide member 173A in left side is fixed in support component 136, and the 73d of guiding terminal portion of the guide member 173A on right side is fixed in the end of stretching out of extended part 134.

Thus, pass through in the portion 127 at the paddy stalk, even the strain of paddy stalk is done side and is significantly shaken because of centrifugal force, can prevent that also it from shaking by the guide member 173B on right side effectively, the strain of this paddy stalk can be done side by about guide member 173A, 173B rapidly and transfer to dried the seizing on both sides by the arms in the transport mechanism 182 of strain of supplying with carrying device 125 reliably.As a result, can prevent because of shifting that the bad paddy stalk that causes stops up or because of shifting the low of the bad chaotic grain rate of recovery that causes of conveyance posture that makes the paddy stalk.

As Figure 15, Figure 18 and shown in Figure 22, above linking part 135A, equipped gripper shoe 218 from the external part of extended part 134 to intermediate member 135, its from the below catch and support from about dial in the lower end that carrying device 124A, 124B transfer to the paddy stalk of supplying with carrying device 125.

Thus, can make from about dial in carrying device 124A, 124B do to the strain of supplying with the paddy stalk that carrying device 125 shifts that side is easier to become neat.As a result, the fringe front side of paddy stalk becomes neat, and residual being difficult to of shelling takes place in the shelling of threshing apparatus 104 is handled, and can improve the grain rate of recovery.

Figure 28 is the left surface figure of reaping part 103 of the another way of expression reaping part 103, and Figure 29 is the front elevation of reaping part 103 of the another way of expression reaping part 103.As shown in these figures, reaping part 103 can be equipped the careless device 219 of branch of driving type by changing left straw-distributing unit 121A between the raising apparatus 122A that parts careless tool 151A and left side on the left side on its left end.

In described embodiment, on shield, formed slit 419, but, can not be that a shield 421 usefulness cutters are only cut off with given length as slit 419, also can cut off in the mode that forms the less slit of width.Perhaps, in another way 1, also can be set up in parallel with the state that between the plate body sheet of the little width of adjacency, forms small gap.

[another way 5 of the 4th embodiment]

In described embodiment, shown that the formed plate body of the resin material that utilizes vinyl chloride comes the example of the shield 421 of moulding curtain-shaped cover member 420, but also can 2 lamellar body weight are folded as plate body, perhaps be the multiple plate body on this.

By changing the overlapping block number of plate body, can change the aperture of identical relatively air quantity, having can be according to the harvesting crop condition of rice or wheat etc., reduces the overlapping block number of plate body during for example by getting wheat during than harvester for rice, can be set at the advantage of the aperture that is fit to the crop condition.

[other different modes]

Utilizing soft vinyl chloride etc. to form under the situation of shield 421 on free strain ground, shaking under the no load condition (not carrying out coming the state of selection by winnowing) under the state that sorting unit 400B driven by rocking back and forth by winnower winnowing machine, (screen box 416 is positioned under the situation of lower position) contacts with the parts that are installed on screen box 416 (for example straw shaker 408) with always in the bottom of shield 421, along with the mode that the sorting action shakes of shaking of screen box 416 constitutes.Thus, can be when preventing that shield 421 from being attracted by dust discharge fan 404, between the plate-like portion of the little width that shakes adjacency by screen box 416 under the job state that shakes selection by winnowing under the low weight load, form the slit, when preventing to lose for the third time, carry out good sorting.

[summary of the 4th embodiment]

As mentioned above, in the combine of this embodiment, be feature with following structure.That is:

A kind of threshing apparatus, below the shelling chamber, be equipped with and shake sorting unit, the below of conveyance upstream side of shaking the handled thing of sorting unit is equipped with winnower winnowing machine, provide sorting wind by the dust-exhausting port of this winnower winnowing machine to the conveyance downstream of handled thing, and be equipped with the curtain-shaped cover member that can cover dust-exhausting port and can change the position in the conveyance downstream of handled thing, wherein curtain-shaped cover member top is hung on the support component, and its below part is formed by a plurality of plate-like portions that can independently shake respectively on the width.

According to this feature, under the more situation of the outer stalk bits of sorting discharge machine, because stronger sorting wind, curtain-shaped cover member rearward retreats significantly, and dust-exhausting port is open significantly.In addition, under the situation that the air quantity of the sorting wind that the treating capacity of the sorting process the during rotation of body etc. is less, supply with from winnower winnowing machine reduces, curtain-shaped cover member shakes to closing direction, and the opening of dust-exhausting port narrows down.

If the shelling treating capacity reduces, even reduce output, reduce the sorting air quantity of winnower winnowing machine a little, moving near the dust-exhausting port grain also has bounce-back (takeofing) and is discharged from tendency outside the machine easily, according to the 1st feature of the present invention, discharge the outer grain of machine, the parts that are masked are caught and are suppressed outside the machine of being discharged to.In addition, curtain-shaped cover member is when top is hung at support component, its below part is formed by a plurality of plate-like portions that can independently shake respectively on width, therefore consider to be worth doing to the stalk of dust-exhausting port discharging, not only at the narrow following side space of curtain-shaped cover member, perhaps shake or stir a plurality of each plate-like portion, outside the slit discharge machine between extended plate-like portion, therefore can carry out the recovery of grain by curtain-shaped cover member well, and reduce by three losses, under the situation that does not produce obstruction, the stalk bits can be discharged to outside the machine well simultaneously, can improve the efficiency of separation.

Therefore, by form the below part of curtain-shaped cover member by a plurality of plate-like portions that can independently shake respectively on the width, when the more high flow capacity for the treatment of capacity, do not hinder the discharge of stalk bits, and when turning to etc. during the less low discharge for the treatment of capacity, even reduce output (sorting air quantity), because each small size plate-like portion is rolled easily or each plate-like portion of adjacency between be easy to generate the slit, therefore when can discharging stalk well, can prevent from effectively to lose for three times.

In order to produce effect like this, a kind of preferred embodiment in, form curtain-shaped cover member with the plate body of elastically deformable, top links to each other on width integratedly, its below part by a plurality of slits on the width about the plate-like portion that blocks formed.In another preferred embodiment, the plate-like portion of curtain-shaped cover member is made of the plate body of a plurality of little width that block from top to bottom.

In addition, also favourable with the synthetic resin formation curtain-shaped cover member of vinyl chloride system.

Thus, though curtain-shaped cover member can be with the vinyl chloride formation of hard, if constitute with soft vinyl chloride, then be rich in softness, the sidepiece with slit is partly rolled easily, even less air quantity, have only a small amount of stalk bits also can be easy to discharge, can improve the dust discharge performance between the slit.

In addition, it also is favourable curtain-shaped cover member can be overlapped with the plate body more than 2 constituting.

Thus, for example under the situation of heavier crop, the plate body more than 2 is overlapped, only need make plate body be not easy to roll and get final product.Thus, can reduce that heavier crop is rolled plate body simply and situation about being discharged from.Otherwise under the situation of lighter crop (for example wheat), only need to reduce the coincidence piece number of plate body, perhaps do not overlap, make plate body to roll simply and get final product with 1 plate body.Thus, can reduce lighter stalk and consider the situation that to roll plate body and can not be discharged to be worth doing.
