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

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

That is, crawler belt 113A, 113B of left and right separate given interval to configure in the lateral direction, make the tip spacing outside their cross-car larger than the working width W being configured to the reaping part 103 that can carry out maximum 4 ridges harvesting conveyances from L.Thereby, it is possible to increase the rut spacing of crawler belt 113A, 113B of left and right, the elongated steering behaviour caused of ground contact length because of each crawler belt 113A, 113B can not be caused low, the performance wet Tanaka can be improved.

In addition, the crawler belt 113A in left side, by making the position of its left part 113Aa consistent in the lateral direction with point careless top 121Aa of left straw-distributing unit 121A, the crawler belt 113A in left side can not protrude on the left of car body from this point of careless top 121Aa.Thus, the left-external side of body 101 exist standing crop Cx periphery harvesting or body 101 the left and right sides outside exist standing crop Cx, Cy central authorities harvesting etc. operation traveling time, can prevent the crawler belt 113A in left side pressure from stepping on the standing crops Cx be positioned near its left-external side, or mud is splashed the generation of the first-class problem of standing crops Cx near its left-external side by the crawler belt 113A in left side, can avoid because the low of the operating efficiency that mud causes is stepped on and spattered to pressure.

On the other hand, the crawler belt 113B on right side, by making the position of its right part 113Ba approximately consistent in the lateral direction with point careless top 121Ba of right straw-distributing unit 121B, standing crop Cx is there is outside the left and right sides of body 101, during the operation travelings such as central authorities' harvesting of Cy, if the crop Cb in the working width between the crop Cy in point working width of careless top 121Ba by reaping part 103 that setting makes right straw-distributing unit 121B outside rightmost crop Cb and the working width adjacent with this crop Cb, can prevent the crawler belt 113B on right side pressure from stepping on the generation of the problem being positioned at standing crops Cy near its right outside side etc., can avoid because pressure steps on the low of the operating efficiency caused.

In addition, the length Lz protruded to the right outside side of car body from point careless top 121Ba of right straw-distributing unit 121B of the crawler belt 113B on right side, only be required to be the length that can prevent the crawler belt 113B on right side pressure from stepping on the standing crops Cy be positioned near the right outside side of car body, such as, from and the relation of plantation interval Sc of crop C, can the various length such as Lz=1/3*Sc or Lz=1/4*Sc be set as, but preferred Lz≤1/6*Sc.So length Lz is shorter for this protrusion, the crawler belt 113B on right side more can be suppressed mud to be splashed standing crops Cy near the right outside side of car body, can prevent from spattering the low of the operating efficiency that mud causes.On the contrary, length Lz is longer for this protrusion, then the rut spacing of left and right crawler belt 113A, 113B is longer, can improve the performance wet Tanaka.

That is, when the operation traveling of periphery harvesting or central authorities' harvesting etc., the specification of comprehensive harvesting that can prevent crawler belt 113A, 113B pressure to standing crops Cx, Cy of left and right from stepping on or standing crops Cx, Cy to be spattered to mud can be formed.

Further, the crawler belt 113B that also can configure right side makes, and point careless top 121Ba of its right part 113Ba and right straw-distributing unit 121B is consistent in the lateral direction, or divides careless top 121Ba closer to body inner side than right straw-distributing unit 121B.In addition, also the crawler belt 113A in left side can be configured, make its left part 113Aa than point careless top 121Aa of left straw-distributing unit 121A closer to body inner side, and, the standing crops Cx be positioned near car body left-external side is stepped on the crawler belt 113A in left side pressure can be prevented, and suppress to spatter in the scope of mud to standing crops Cx, also can configure and make its left part 113Aa than point careless top 121Aa of left straw-distributing unit 121A closer to car body left-external side.

As shown in figure 24, 3 nearside divider 121A ~ 121C configurations make, when the operation traveling of harvesting 4 ridge culture thing C, relative for right straw-distributing unit 121B crop C is adjusted position, between the harvesting track Cz making crop Cy outside the working width on the right side that rightmost crop Cb is adjacent with this crop Cb in the working width of its point of careless top 121Ba by reaping part 103 or crop, when the side of the crop Cb in working width is other, middle nearside divider 121C is by becoming 2 ridge culture thing Cc of the medial side on the left and right directions in the working width of its effective object, the centre position of Cd or roughly centre position, and, left straw-distributing unit 121A is by between the harvesting track Cz of the crop Cx outside the working width in leftmost crop Ca in the working width of reaping part 103 and the left side adjacent with this crop Ca or crop, than their centre position closer to the position of the crop Ca in working width.

Namely, when the operation traveling of 4 ridge harvestings, front lower place because being positioned at Drive Section 102 being made adjust position from a point careless top 121Ba of the high right straw-distributing unit 121B of Drive Section 102 visibility makes near its right cross side passing through to be positioned at the rightmost crop Cb of working width, thus for because of away from Drive Section 102 from the low left straw-distributing unit 121A of Drive Section 102 visibility and middle nearside divider 121C, their visual confirmation need not be carried out, can pass through from the suitable position of the planting location departing from crop C, these nearside dividers 121A can be avoided, 121C pushes over or presses and steps on crop C.

Thus, when the serious lodging of the C of crop, easily and reliably each nearside divider 121A ~ 121B can being adjusted position to corresponding on the suitable position of crop C, can prop up by the efficiency paddy stalk that carries out raising apparatus 122A, 122B of each nearside divider 121A ~ 121B and left and right well.

In addition, because middle nearside divider 121C is by being positioned at centre position or the roughly centre position of 2 crops Cc, the Cd of the center side on the left and right directions of working width, therefore, it is possible to the paddy stalk making to import to 2 ridge culture thing Ca, Cc in the framework propping up framework 126A in left side and the paddy stalk of 2 ridge culture thing Cb, Cd that imports in the framework propping up framework 126B on right side are located at directly over middle nearside divider 121C, on the symmetrical position of paddy stalk passage 127, the paddy stalk that can make to become its left and right object similarly shortens from the distance of paddy stalk passage 127.

Thus, make left and right prop up the paddy stalk of the crop C importing 2 ridges in framework 126A, 126B respectively while, middle nearside divider 121C is away from the centre position of 2 crops Cc, Cd of the center side be positioned on the left and right directions of working width, can prevent import left and right the paddy stalk of any one propped up in framework 126A, 126B unnecessarily elongated from the distance of paddy stalk passage 127, left and right any one dial in carrying device 124A, 124B paddy stalk conveyance efficiency reduce.In addition; any one dial in the conveyance of the paddy stalk of carrying device 124A, 124B and produce unnecessary delay of left and right can be prevented; can prevent: due to the confusion of the conveyance posture of the paddy stalk that is cause with this delay; neat variation on front side of fringe when paddy stalk being transported to threshing apparatus 104 by supply carrying device 125; when the shelling process of threshing apparatus 104, shelling easily occurs to remain, namely the grain rate of recovery is low.

And, due to left straw-distributing unit 121A by the left side that is positioned at the leftmost crop Ca of working width laterally near, when the operation traveling of harvesting 4 ridge culture thing C, all the time following needs are had: position adjustment is carried out to a point careless top 121Ba of right straw-distributing unit 121B, near the right side making it pass through to be positioned at the rightmost crop Cb of working width is horizontal.

Thus, when the operation traveling of harvesting 4 ridge culture thing C, each nearside divider 121A ~ 121C can be made all the time reliably by relative to the above-mentioned correct position of crop C, result, the raising of workability when can realize the operation traveling of harvesting 4 ridge culture thing C.

As shown in figure 25, 3 nearside divider 121A ~ 121C configurations make, when the operation traveling of harvesting 3 ridge culture thing C, right straw-distributing unit 121B is adjusted position relative to the harvesting track Cz of the crop on right side, make its point of careless top 121Ba by above the harvesting track Cz of the crop on the right side adjacent with rightmost crop Cb in the working width of reaping part 103 when, middle nearside divider 121C is by 2 crop Cb than the center side be positioned on the right side of the working width becoming its effective object and left and right directions, the crop Cb on the right side between Cc is closer to the position of the crop Cc of the center side on left and right directions, and, left straw-distributing unit 121A is by the centre position between the harvesting track Cz of the crop Cx outside the working width in leftmost crop Ca in the working width that becomes the reaping part 103 of its effective object and the left side adjacent with this crop Ca or crop or roughly centre position.

Namely, when the operation traveling of 3 ridge harvestings, front lower place because being positioned at Drive Section 102 being made adjust position from a point careless top 121Ba 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, thus for because of away from Drive Section 102 from the low left straw-distributing unit 121A of Drive Section 102 visibility and middle nearside divider 121C, their visual confirmation need not be carried out, can pass through in the suitable position of the planting location leaving crop C, these nearside dividers 121A, 121C can be avoided to push over or press and step on crop C.

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

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

Thus, the conveyance efficiency dialled in when 3 ridge paddy stalks are dialled in conveyance to paddy stalk passage 127 by carrying device 124A, 124B improved by left and right can be crossed.In addition; any one dial in the conveyance of the paddy stalk of carrying device 124A, 124B and produce unnecessary delay of left and right can be prevented; can prevent: due to the confusion of the conveyance posture of the paddy stalk that is cause with this delay; neat variation on front side of fringe when paddy stalk being transported to threshing apparatus 104 by supply carrying device 125; when the shelling process of threshing apparatus 104, shelling easily occurs to remain, namely the grain rate of recovery is low.

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

In addition, as the concrete configuration of 3 nearside divider 121A ~ 121C of the position relationship for meeting above-mentioned 3 nearside divider 121A ~ 121C and crop C, the relation between left and right between Sa, Sb and the plantation interval Sc of crop C of 3 nearside divider 121A ~ 121C, the configuration of the configuration of Sa=Sb=1.75*Sc, Sa=Sb ≒ 1.75*Sc can be thought of as, or Sa ≒ 1.75*Sc under Sa > Sb and the configuration of Sb ≒ 1.75*Sc, or Sa is less than Sa ≒ 1.75*Sc under Sb and the configuration etc. of Sb ≒ 1.75*Sc.And, when the operation traveling of harvesting 4 ridge culture thing C, left straw-distributing unit 121A and the spacing distance La of the leftmost crop Ca being positioned on the right side of it horizontal working width is preferably made to be greater than right straw-distributing unit 121A and the spacing distance Lb of rightmost crop Cb being positioned at working width horizontal on the left of it.

As shown in Figure 12,13 and Figure 17, the posture that nearside divider 121A, 121B of left and right form point careless tool 151A, the 151B making them is the inclination attitude of the body inner side being located car body left and right directions the closer to rear vehicle side.Thereby, it is possible to make the easier central authorities on the left and right directions of working width of crop Ca, the Cb at the both ends, left and right of the working width being positioned at reaping part 103 close.

As shown in Figure 10 ~ Figure 13 and Figure 15 ~ Figure 18, the leading section of the left and right directions of reaping part 103 is equipped with and parts careless bar 199A on the left side, part careless bar 199B on the right side and be arranged in this point careless bar 199C parting careless bar 199A on the left side and part the central authorities on the left and right directions of careless bar 199B on the right side.

As shown in Figure 10, Figure 12, Figure 13 and Figure 15, part the left side that careless bar 199A is equipped in reaping part 103 on the left side, make it pass through shake, posture conversion can be carried out between the effect posture tilted to left outside side's mode of stretching out of body 101 and the storage posture erected being retracted into body side.Further, be switched to effect posture by careless bar 199A will be parted on the left side, the standing crops Cx of the left-external side being present in body 101 can be stoped to the lodging in body inner side direction.

Figure 26 is the stereogram of the major part of the mounting structure representing point careless terminal part side parting careless bar 199A on the left side.As shown in Figure 10, Figure 12, Figure 13, Figure 15 and Figure 26, part careless bar 199A on the left side and its point of careless top portion 199a joltily can be linked to by the 1st linking part 200 part on the left side on careless tool 151A.In addition, the projecting end 201a of the connecting rod 201 stretched out from this point of careless terminal part side can be joltily linked on the support component 136 of reaping part 103 by the 2nd linking part 202.

1st linking part 200 parts L-shaped bracket 203 on careless tool 151A on the left side by being welded in and being formed by the connecting pin 204 that point careless top portion 199a parting careless bar 199A on the left side can joltily be linked on this bracket 203, and makes connecting pin 204 close to the left side parting careless tool 151A on the left side.

2nd linking part 202 by be welded in support component 136 bracket 205, the projecting end 201a of connecting rod 201 joltily can be linked to the connecting pin 206 on this bracket 205 and the maintaining body 207 of the posture parting careless bar 199A on the left side can be kept to form.And, effective utilize left side prop up the space that the position, dead astern of the left end on framework 126A exists, configuration makes to be positioned at than the 1st linking part 200 closer to the center side on the left and right directions of reaping part 103, and than the left part 113Aa of the crawler belt 113A in left side closer to the center side on the left and right directions of body 101.

Maintaining body 207 is configured to, bracket 205 defines the elongated hole 205a of the arc-shaped centered by connecting pin 206, after bolt 208 is inserted through this elongated hole 205a, the outer Compress Spring 209 in side, top is inserted through at this bolt 208, screw togather a pair nut 210, under the effect of Compress Spring 209, by crimping projecting end 201a and the bracket 205 of connecting rod 201, while allowing the shake operation between effect posture and storage posture carrying out parting on the left side careless bar 199A along elongated hole 205a, the posture carrying out parting on the left side careless bar 199A keeps.

By above-mentioned structure, even if the 2nd linking part 202 formed in the large-scale mode being equipped with maintaining body 207, when the posture parting careless bar 199A on the left side is switched to storage posture, when the crop C making the left part of reaping part 103 be positioned at Bian Duigeng limit, the ridge carries out the operation traveling of gathering in etc. in situation, other objects such as the 2nd linking part contact ridge can be avoided and be out of shape.This is being formed in the field of lower ridge by concrete block etc., prevent from causing in the distortion of the 2nd linking part 202 because contacting this concrete block especially effective.

In addition, the inclination attitude being located the center side on the left and right directions of reaping part 103 the closer to the rear portion side of reaping part 103 by the shake axle center P parting careless bar 199A on the left side at the center of the connecting pin 204 of the 1st linking part 200 and the connecting pin 206 of the 2nd linking part 202, therefore compared with the posture shake axle center P parting careless bar 199A on the left side is set as along the fore-and-aft direction of reaping part 103, can reduce by part on the left side careless bar 199A receive posture and effect posture between carry out shake operation time operation angle, the operability parting careless bar 199A on the left side can be improved.

Figure 27 is the vertical view that display parts that careless bar 199A is switched to the major part of the state of storage posture on the left side.As shown in Figure 13 and Figure 27, part careless bar 199A on the left side to be configured to, in its storage posture, under its point of careless terminal part 199b is positioned at left end side than reaping part 103 state closer to the center side on the left and right directions of body 101, its point of careless terminal part 199b is approximately consistent with the position of left end side on car body left and right directions of reaping part 103.

Thus, part careless bar 199A on the left side, in its storage posture, under its point of careless terminal part 199b is positioned at left part 113Aa than the crawler belt 113A in the left side state closer to the center side on the left and right directions of body 101, its point of careless terminal part 199b is approximately consistent with the position of left part 113Aa on car body left and right directions of the crawler belt 113A in left side.

Namely, storage posture is switched to by careless bar 199A will be parted on the left side, point careless terminal part 199b that can make to part on the left side careless bar 199A is positioned at left part 113Aa than the left-hand end of reaping part 103 and the crawler belt 113A in left side closer to the center side on the left and right directions of body 101, thus, the entirety parting careless bar 199A on the left side can be made than the body inner side of left outside side closer to car body left and right directions of seizing transport mechanism 131 on both sides by the arms, and wherein this seizes the left part 113Aa of transport mechanism 131 than the crawler belt 113A in left side on both sides by the arms closer to car body left-external side.Result, the left outside side of seizing carrying device 131 on both sides by the arms with point careless terminal part 199b geometric ratio parting careless bar 199A on the left side closer to the left outside side of car body situation compared with, the left and right width of entirety parting the combine that careless bar 199A is switched under storage posture state on the left side can be diminished, the storage to garage etc. can be improved.

Parting careless bar 199A formation on the left side makes under its storage posture, and its point of careless terminal part 199b transports path 188 closer to car body upper side than the paddy stalk of supply carrying device 125.Thus, even if by under parting state that careless bar 199A is switched to storage posture on the left side, paddy stalk can be transported to threshing apparatus 104 when not contacting point careless terminal part 199b parting careless bar 199A on the left side by supply carrying device 125.

That is, even if carrying out operation traveling by parting on the left side under careless bar 199A is switched to the state of receiving posture, the paddy stalk transported by supply carrying device 125 can be avoided to contact point careless terminal part 199b parting careless bar 199A on the left side.As a result, can avoid: due to the confusion of conveyance posture of the paddy stalk that is cause with this contact and the neat variation on front side of the fringe caused, when the shelling process of threshing apparatus 104, shelling easily occurring remains, and namely the grain rate of recovery is low.

And, by part on the left side careless bar 199A be switched to storage posture state under, due to the entirety that parts careless bar 199A on the left side than the left outside side of seizing carrying device 131 on both sides by the arms of threshing apparatus 104 closer to the body inner side direction on car body left and right directions, therefore under carrying out the situations such as operation traveling on limit, the ridge, car body can be made to carry out operation traveling closer under the state of ridge, more easily carry out left straw-distributing unit 121A and the position of the crop C on limit, the ridge is adjusted.As a result, the workability on limit, the ridge can be improved.

In addition; for the crop C of the less short stalk of worry that stalk length is about 65 ~ 75cm, lodging; be switched to storage posture and make to part careless bar 199A on the left side by careless bar 199A will be parted on the left side and do not act on its fringe end; can avoid making grain depart from paddy stalk because parting point grass effect of careless bar 199A to the paddy stalk of crop C on the left side; as a result, grain organic efficiency can be improved.This is particularly effective when gathering in the long-grained nonglutinous rice etc. of easy threshing.

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

Thus, by the effect of dialling in of respectively propping up pawl 159A, 159B in guidance field Aa1, Ab1 of each raising apparatus 122A, 122B of left and right to raising apparatus 122A, 122B lodging of another side thus the paddy stalk of the crop C becoming to report to the leadship after accomplishing a task from visual angle, car body front on the car body front of propping up region Aa1, Ab1 of each raising apparatus 122A, 122B pass through in point grass effect of point careless bar 199C, prop up region Aa1, Ab1 towards corresponding raising apparatus 122A, 122B separate to the left and right.

Result, the paddy stalk of gathered in crop C can be avoided because of respectively propping up the dialling in effect of pawl 159A, 159B and intersect at the car body front side propping up region Aa1, Ab1 of each raising apparatus 122A, 122B from visual angle, car body front and entwine in guidance field Aa1, Ab1 of each raising apparatus 122A, 122B, the crop paddy stalk that can prevent from it from entwining causing to prop up efficiency beneath or prop up bad generation.

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

Thus, framework 126B is equipped with prop up region Ab2 is positioned at compared with the situation of the 2 ridge raising apparatus that the mode for the right side of Drive Section side is formed with propping up of right side, can make from the sight line in Drive Section 102 pairs of car body fronts better, can improve from the visibility that waits of the operation in Drive Section 102 pairs of car body fronts ground.

Raising apparatus 122A, 122B of left and right are formed corresponding to the mode of the width propped up of the paddy stalk on maximum 2 ridges to make their the left and right width W a, the Wb that prop up region Aa2, Ab2.In addition, upper prop up pawl 159A, the 159B be equipped with of raising apparatus 122A, 122B of left and right defines the corresponding wider length propping up region Aa2, Ab2.

Thus, when raising apparatus 122A, 122B of carrying out left and right prop up the operation traveling of 4 ridges harvestings of the paddy stalk on 2 ridges all the time respectively, can prevent paddy stalk by left and right correspondence prop up region Aa2, Ab2 time resistance exceed permissible range.As a result, when carrying out the operation traveling of 4 ridge harvestings, the paddy stalk that smoothly and well can carry out left and right raising apparatus 122A, 122B is propped up.

In addition, define the corresponding wider length propping up region Aa2, Ab2 owing to making respectively to prop up pawl 159A, 159B, can prevent from propping up in wider formation in region Aa2, Ab2 of propping up the dead band that pawl 159A, 159B do not act on paddy stalk.As a result, make that raising apparatus 122A, 122B's of left and right respectively prop up while region Aa2, Ab2 define the width of allowing that 2 ridge paddy stalks pass through, reliably can carry out raising apparatus 122A, 122B propping up paddy stalk of left and right.

And, no matter be when the operation traveling of 3 ridge harvestings or when the operation traveling of 4 ridge harvestings, only make to supply its left and right width W a propping up region Aa2 of raising apparatus 122A in the left side giving 2 ridge paddy stalks to define the width propped up of corresponding maximum 2 ridge paddy stalks all the time, further, it is propped up pawl 159A and can be configured to the corresponding wider length propping up region Aa2.

As shown in Figure 11, Figure 14 and Figure 16 ~ Figure 18, the right part that cutting knife driving device 170 is configured at intermediate member 135 makes to be positioned at the right-hand end of reaping part 103.Thus, the harvested paddy stalk caused when the center side be provided to by cutting knife driving device 170 on the left and right directions of reaping part 103 can be prevented to be wound in the undesirable of cutting knife driving device 170, and cause when cutting knife driving device 170 is provided to the left-hand end of reaping part 103 only when there is the operation traveling of the higher periphery harvesting of the operation frequency of standing crop Cx in the left outside side of body 101 this standing crops Cx to be wrapped on cutting knife driving device 170 undesirable.

In addition, the position kept left being configured on reaping part 103 because making supply carrying device 125 makes to dial in the threshing apparatus 104 of the paddy stalk being transported to paddy stalk passage 127 on the left of car body and supply conveyance, the cutting knife driving device 170 that weight ratio is larger is provided to the right-hand end of the heavier reaping part 103 in left side, can improve the left-right balance of reaping part 103.

The right-hand end of reaping part 103 is configured with the lid 211 of the metallic plate covering cutting knife driving device 170.Lid 211 utilizes two bolts 212 of the upside among 3 bolts 212 right straw-distributing unit 121B being attached to the right part of intermediate member 135, with the right part parting careless bar 199B on the right side and be jointly attached to intermediate member 135.

Thus, when there is the operation traveling of central authorities' harvesting of standing crops Cy in the right outside side of body 101, owing to parting careless bar 199B and lid 211 on the right side, the right lateral standing crops Cy of this car body can be avoided to be wound on cutting knife driving device 170.

In addition, with bolt by right straw-distributing unit 121B, part careless bar 199B on the right side and cover 211 situations being linked to the right part of intermediate member 135 respectively and compare, can assembleability be improved.And, when carrying out the replacing parting careless bar 199B and lid 211 on the right side, while can preventing right straw-distributing unit 121B from unloading completely from the right part of intermediate member 135, carry out their replacing.

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

And, dial in carrying device 124A, 124B in left and right, when left and right dial in transport mechanism 171A, 171B by rubber dial in belt 174A, 174B carry out paddy stalk dial in conveyance and paddy stalk before acting on harvesting, protuberance 174a, 174b of dialling in belt 174A, 174B are out of shape because of the intensity of the paddy stalk before harvesting, by this distortion, until before gathering in this paddy stalk, this paddy stalk can not be dialled in conveyance to paddy stalk passage 127.In addition, by operation traveling now, the paddy stalk before harvesting is bent to car body front.

Therefore, when the paddy stalk of press-bending like this arrives the harvested position of reaping apparatus 123 and is gathered in, while harvesting, sometimes under getting back to the reactivation of straight state from bending to the state in car body front, jump out to the car body front side dialling in transport mechanism 171A, 171B away from left and right, leave the conveyance region dialling in transport mechanism 171A, 171B of left and right, be scattering into the front of reaping apparatus 12.

If there is such phenomenon, what the paddy stalk being scattering into the front of reaping apparatus 12 was imported successively by the conveyance region dialling in transport mechanism 171A, 171B to the left and right along with operation traveling follow-up does not receive harvested cereal culm by the harvested position of getting back to reaping apparatus 12, and its strain is done side and again gathered in together with the paddy stalk do not gathered in.

If there is the secondary harvesting of such paddy stalk; then the bar of paddy stalk is long becomes not neat; not neat by this is cause; neat variation on front side of fringe when paddy stalk is transported to threshing apparatus 104; so; shelling easily occurs when the shelling process of threshing apparatus 104 remain, result, easily causes the low of grain organic efficiency.

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

The posture dialling in transport mechanism 171A, 171B of setting left and right if so, then multiplely moving knife 168 and dead knife 169 can make its linearly continuous arrangement in the lateral direction by being arranged above reaping apparatus 123, can make straight line transport path 214A, 214B relative to linearity arrangement in the lateral direction respectively can moving knife 168 and dead knife 169 harvested position and be positioned at roughly along the state of harvested position.

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

In addition, the paddy stalk just gathered in by reaping apparatus 123 can be made promptly to dial in conveyance to paddy stalk passage 127 by dial in carrying device 124A, 124B of left and right, as a result, dial in carrying device 124A, the 124B that can improve left and right dial in conveyance efficiency to paddy stalk.

As shown in Figure 17 and Figure 22, dial in carrying device 124A, 124B in left and right, guide member 173A, 173B are equipped with from the end of the left and right of reaping part 103 to straight line guide portion 173a, the 173b that the pivot of packer 172A, 172B of the left and right of correspondence extends.Each straight line guide portion 173a, 173b are formed as the horizontal linearity of vertical car body fore-and-aft direction.

Thus, straight line guide portion 173a, the 173b of guide member 173A, 173B of left and right, when operation traveling, act on the paddy stalk before harvesting, and this paddy stalk can be prevented to be bent to car body front.As a result, the paddy stalk of this press-bending can be avoided to become scattered about the front of reaping apparatus 12 when gathering in by the reactivation from press-bending state and gathered in by secondary.

As shown in Figure 12 and Figure 23, supply carrying device 125 to set it from the mode that visual angle, car body front overlaps with Drive Section 102 transport posture to transport top portion 125b.Thus, by being formed reaping part 103 with the specification of 2 framework 4 ridge harvestings, make the position consistency of left part 113Aa on car body left and right directions of point careless top 121Aa of left straw-distributing unit 121A and the crawler belt 113A in left side, and point careless top 121Ba of right straw-distributing unit 121B is roughly consistent with the position of right part 113Ba on car body left and right directions of the crawler belt 113B on right side, then relative to the paddy stalk passage 127 of the pars intermedia be positioned on the left and right directions of car body 101, the conveyance top portion 125b of supply carrying device 125 can be made to be positioned on the position in the dead astern of the paddy stalk passage 127 that directly can receive the paddy stalk after by paddy stalk passage 127.

That is, can obtain transporting structure in the supply that do not carry out the auxiliary carrying device of transfer to the handing-over of paddy stalk between carrying device 124A, 124B and supply carrying device 125, that be suitable for gathering in 2 framework 4 ridges the reaping part 103 that specifications are formed of dialling in of left and right.

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

Supply carrying device 125 increases the tiltangleθ d from straight line conveyance path 216 to car body left and right directions that seize the straight line conveyance tiltangleθ c from path 215 to car body left and right directions of transport mechanism 182 and fringe end relative to car body fore-and-aft direction locking transport mechanism 183 dry relative to the strain of car body fore-and-aft direction, makes recess 102a conveyance top portion 125b being entered Drive Section 102.

Thus, compared with Drive Section 102 not being formed the situation of recess 102a, the side, portion, conveyance top of supply carrying device 125 can be made close to Drive Section 102, the length on the car body fore-and-aft direction of supply carrying device 125 can be shortened thus, the total length of combine can be shortened.

In addition, along with the side, conveyance top of supply carrying device 125 is closer to Drive Section 102, thus, the action bars 198 that the treating depth that the support frame 190 of supply carrying device 125 is equipped with regulates is also closer to Drive Section 102, as a result, the operation to the action bars 198 that treating depth regulates can more easily be carried out from Drive Section 102.

Further, if increase supply carrying device 125 relative to tiltangleθ c, θ d of car body fore-and-aft direction to car body left and right directions, then supply carrying device 125 and dial in transport mechanism 171A near left side.Therefore, the strain of paddy stalk transported by supply carrying device 125 is done and is dialled in transport mechanism 171A on the left of side contacts, causes the conveyance posture of paddy stalk chaotic.

Therefore, as shown in Figure 10, Figure 11, Figure 14 ~ Figure 16 and Figure 18, in this combine, the height and position dialling in transport mechanism 171A in left side is configured to than right side to dial in transport mechanism 171B lower.Thus; can prevent the strain of the paddy stalk transported by supply carrying device 125 from doing dialling in transport mechanism 171A and causing the conveyance posture of its paddy stalk chaotic on the left of side contacts; can prevent: be cause by this confusion; neat variation on front side of fringe when paddy stalk being transported to threshing apparatus 104 by supply carrying device 125; when the shelling process of threshing apparatus 104, shelling easily occurs to remain, namely grain organic efficiency is low.

In addition, if the transport mechanism 171A that dials in left side is configured to 2 ridges use, and increase supply carrying device 125 relative to tiltangleθ c, θ d of car body fore-and-aft direction to car body left and right directions, then the paddy stalk that framework 126A gathers in propped up in left side is transported with roughly U-shaped by dialling in transport mechanism 171A and the supply carrying device 125 in left side.Therefore, become this roughly U-shaped conveyance paddy stalk conveyance direction switching place paddy stalk passage 127 on, side is done in the strain of this paddy stalk the tendency of significantly shaking because of centrifugal force.

Therefore, as shown in Figure 10, Figure 11, Figure 15 ~ Figure 19 and 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, depart to car body rear side from paddy stalk passage 127 by making extended part 134, between extended part 134 and intermediate member 135, define and can allow that side is passed through, that front and back width is larger transferring path 217 is done in the strain of paddy stalk that carrying device 124A, 124B transfer to supply carrying device 125 of dialling in from left and right.

Thus; in paddy stalk passage; even if the strain of paddy stalk is done side and is significantly shaken because of centrifugal force; also can prevent the strain of this paddy stalk from doing the external part of side contacts extended part 134; the confusion of the conveyance posture of the paddy stalk brought by this contact can be prevented and neat variation on front side of the fringe of the paddy stalk caused; shelling easily occurs in the shelling process of threshing apparatus 104 remain, namely the grain rate of recovery is low.

In addition, configure extended part 134 to be located at than the left end side of paddy stalk passage 127 closer to reaping part 103.Thus, in paddy stalk passage 127, can prevent the strain of the paddy stalk significantly shaken because of centrifugal force from doing the external part of side contacts extended part 134 more reliably, the low of the grain rate of recovery caused because of this contact can be prevented more reliably.

Further, guide member 173A, 173B of dialling in carrying device 124A, 124B of forming left and right make the strain of the paddy stalk by paddy stalk passage 127 to be done side direction supply carrying device 125 and guide, and, the guiding terminal portion 173c of the guide member 173A in left side is fixed on support component 136, and the guiding terminal portion 173d of the guide member 173B on right side is fixed on the projecting end of extended part 134.

Thus, in paddy stalk passage 127, even if the strain of paddy stalk is done side and is significantly shaken because of centrifugal force, also effectively can prevent it from shaking by the guide member 173B on right side, the strain of this paddy stalk can be done side by guide member 173A, 173B of left and right rapidly and reliably transfer to that the strain of supply carrying device 125 is dry seizes on both sides by the arms in transport mechanism 182.As a result, can prevent because shifting the bad and paddy stalk blocking that causes or badly making the conveyance posture of paddy stalk chaotic and the grain rate of recovery that causes low because shifting.

As shown in Figure 15, Figure 18 and Figure 22, above linking part 135A, be equipped with gripper shoe 218 from the external part of extended part 134 to intermediate member 135, it is caught from below and supports and dials in from left and right the lower end of paddy stalk that carrying device 124A, 124B transfer to supply carrying device 125.

Thereby, it is possible to make to do side from the strain dialling in the paddy stalk that carrying device 124A, 124B shift to supply carrying device 125 of left and right more easily become neat.As a result, become neat on front side of the fringe of paddy stalk, in the shelling process of threshing apparatus 104, shelling residual being difficult to occurs, and can improve the grain rate of recovery.

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

So, by utilize light weight can free elastic deformation resin come shaping curtain-shaped cover member 420, be configured to can according to the air quantity of the sorting wind sent here from the rearward dust-exhausting port 427 of winnower winnowing machine 410 make curtain-shaped cover member 420 rearward increase shake.

Specifically describe, under the air quantity of winnower winnowing machine 410 is set to maximum state, the shield 421 be hung on the support component 422 of curtain-shaped cover member 420 significantly rearward bends, the bottom rearward top shake of shield 421, and significantly opening between dust discharge aulaeum 428, stalk bits are discharged outside machine.

In shield 421, owing to crossing slit 419 that half portion cut off by above-below direction except outer lower side, upper end and defining the plate-like portion 421a of multiple little width in the direction of the width, plate-like portion 421a from the stronger place of the wind of winnower winnowing machine 410 is corresponding to its air quantity, the place that rearward amount of bow compares wind less is larger, define the opening corresponding to air quantity, tier pole can be discharged outside machine with the opening amount corresponding to air quantity, compare than the masking device not cutting slit in the past, treatment effeciency is higher.

In the light hours that shelling treating capacity diminishes, slow down to export that the air quantity of winnower winnowing machine 410 is died down.Now, curtain-shaped cover member 420 closes dust-exhausting port 427 automatically covering, if comprise the stalk bits of the not recoverable grain of retracting device 400C from front supply, then this grain and stalk bits are encountered on curtain-shaped cover member 420, and the heavier grain of proportion drops in screen box 416.Even if the stalk bits that proportion is lighter have encountered curtain-shaped cover member 420, also along with the sorting wind supplied from winnower winnowing machine 410 is by between curtain-shaped cover member 420 and screen box 416, be directed to rear.So, when low discharge, even if bounce-back grain will be discharged outside machine, also can stop from dust-exhausting port discharge and lead in screen box 416 by crested parts 420, the third time loss of discharging from dust-exhausting port 427 can be reduced.

[another way 1 of the 4th embodiment]

In the embodiment shown, the one piece of plate body be connected integratedly in the direction of the width by top forms shield 421, but also can form shield 421 by the plate body (plate-like portion) being arranged side by side multiple little width blocked from top to bottom in the direction of the width.

[another way 2 of the 4th embodiment]

In the embodiment shown, with the soft vinyl chloride resin of free elastic deformation forming shield 421, but when the plate body of the little width by blocking from top to bottom forms shield 421, shield 421 can be formed with the plate body of the vinyl chloride of hard or other elastic deformation difficulty, and the mode being maintained given angle posture when non-operation by the force application part of helical spring etc. rotatably supports each plate body around transverse axis, corresponding to the pressing force that stalk is considered to be worth doing when operation, the mode that each plate body separately rotates around transverse axis is formed.

[another way 3 of the 4th embodiment]

In the embodiment shown, show curtain-shaped cover member 420 and carry out shaping example to utilize the plastic material of vinyl chloride, as long as same function can be reached, synthetic rubber, plastic plate etc. that thickness is thin can be adopted.

[another way 4 of the 4th embodiment]

In the embodiment shown, shield defines slit 419, but as slit 419, can not be that one piece of shield 421 cutter is only cut off with given length, also can cut off in the mode forming the less gap of width.Or, in another way 1, also can be set up in parallel with the state forming small gap between the tabular body piece of adjacent little width.

[another way 5 of the 4th embodiment]

In the embodiment shown, show the example that the one piece of plate body utilizing the resin material of vinyl chloride to be formed carrys out the shield 421 of shaping curtain-shaped cover member 420, but can using folded for 2 pieces of lamellar body weight as plate body, or be also the multiple plate body on this.

By changing the overlapping block number of plate body, the aperture of relatively identical air quantity can be changed, having can according to the harvesting crops condition of rice or wheat etc., such as by during getting wheat than the overlapping block number reducing plate body during harvester for rice, the advantage of the aperture of applicable crops condition can be set as.

[other different modes]

When utilizing soft vinyl chloride etc. can form shield 421 to free elastic deformation, sorting unit 400B is shaken by under the state of the driving that rocks back and forth under no load condition (not carrying out the state being carried out selection by winnowing by winnower winnowing machine), with always, (when screen box 416 is positioned at bottom position) contacts with the parts (such as straw shaker 408) being installed on screen box 416 in the bottom of shield 421, and the mode that the shake sorting action along with screen box 416 is shaken is formed.Thus, can prevent shield 421 by dust discharge fan 404 attract while, form gap between the plate-like portion of the little width adjoined by the shake of screen box 416 carry out shaking the job state of selection by winnowing under lighter load under, while preventing third time loss, carry out good sorting.

[summary of the 4th embodiment]

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

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

According to this feature, when the stalk because of sorting outside discharge machine is considered to be worth doing more, due to stronger sorting wind, curtain-shaped cover member rearward retreats significantly, and dust-exhausting port is opening significantly.In addition, the treating capacity of the sorting process during rotation of body etc. is less, reducing from the air quantity of the sorting wind of winnower winnowing machine supply, curtain-shaped cover member shakes to closing direction, and the opening of dust-exhausting port narrows.

If shelling treating capacity reduces, export even if reduce, reduce the sorting air quantity of winnower winnowing machine a little, the tendency that the grain moved near dust-exhausting port also has bounce-back (takeofing) and is easily discharged outside machine, according to the 1st feature of the present invention, will grain outside discharge machine, the parts that are masked are caught and to be suppressedly discharged to outside machine.In addition, curtain-shaped cover member is while top is hung at support component, its inferior portion is formed by multiple plate-like portions that can independently shake in the direction of the width, therefore to the stalk bits of dust-exhausting port discharge, not only at the narrow underlying space of curtain-shaped cover member, or shake or stir multiple each plate-like portion, from the gap discharge machine between extended plate-like portion, therefore, it is possible to carried out the recovery of grain well by curtain-shaped cover member, and reduce by three losses, stalk bits can be discharged to outside machine well when not producing blocking simultaneously, the efficiency of separation can be improved.

Therefore, by being formed the inferior portion of curtain-shaped cover member by multiple plate-like portions that width can independently shake, the discharge not hindering stalk to consider to be worth doing when the high flow capacity that treating capacity is more, and during treating capacity is less when turning to etc. low discharge, (sorting air quantity) is exported even if reduce, because small size each plate-like portion is easily rolled or easily produce gap between adjacent each plate-like portion, therefore while can discharging stalk well, can effectively prevent from losing for three times.

In order to produce effect like this, one preferred embodiment in, with the plate body of elastically deformable formed curtain-shaped cover member, top is connected in the direction of the width integratedly, and its inferior portion is driven by slit multiple on width the plate-like portion blocked and is formed.In another preferred embodiment, the plate-like portion of curtain-shaped cover member is made up of the plate body of the multiple little width blocked from top to bottom.

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

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

In addition, it is also favourable for enabling curtain-shaped cover member be formed with the plate body of more than 2 pieces coincidence.

Thus, such as, when heavier crop, the plate body of more than 2 pieces is overlapped, only plate body need be made to be not easy to roll.Thereby, it is possible to the situation reducing heavier crop to roll plate body simply and be discharged.Otherwise when lighter crop (such as wheat), only need reduce the coincidence block number of plate body, or not overlap with 1 piece of plate body, plate body can be rolled simply.Thereby, it is possible to the situation reducing lighter stalk bits to roll plate body and can not be discharged.

Industrial practicality

As mentioned above, the present invention can be used in and the strain of receiving harvested cereal culm is done side by feeding chain maintenance, conveyance, and by shelling tooth to the head feeding type combined harvester carrying out shelling process on front side of fringe.Further, the structure of each embodiment, just can be applied in same combine so long as not contrary.
