Be equipped with the fringe end sensor 195 that detects by the fringe end position of the paddy stalk of supplying with 125 conveyances of carrying device on support frame 190.Pair of sensors arm 196A, 196B have been equipped with on fringe end sensor 195.Pair of sensors arm 196A, 196B configure to separate the mode of placing at given interval on the stalk length direction in the fringe front side of the paddy stalk by supplying with 125 conveyances of carrying device.And fringe end sensor 195 will be outputed to by the fringe end position of pair of sensors arm 196A, the detected paddy stalk of 196B and utilize in the control device 197 that microcomputer forms.In control device 197, be equipped with and processed the control module 197A that depth adjustment is used, this control module is based on the output of fringe end sensor 195, and the action of the electromotor 191 of control and regulation unit 187 makes the length of fringe front side of the paddy stalk of the inside that supplies to threshing apparatus 104 fix.Control module 197A is by controlling the action of electromotor 191, make to maintain the strain that is positioned at the paddy stalk and do the sensor arm 196B that the sensor arm 196A of side detects the fringe front side of paddy stalk and be positioned at the fringe front side of paddy stalk and can't detect the state of the fringe front side of paddy stalk, thereby make the length of fringe front side of the paddy stalk of the inside that supplies to threshing apparatus 104 fix.
Although the diagram of omission, a pair of sensor arm 196A, 196B constitute the position change on the stalk length direction that can carry out integratedly with respect to the paddy stalk of supplying with 125 conveyances of carrying device.Then, by this position change, the side change is done to the strain of paddy stalk in the position of two sensors arm 196A, 196B, the paddy stalk of threshing apparatus 104 can be processed thus the shallow processing side that depth adjustment shortens to the fringe end length of the paddy stalk that makes the inside that supplies to threshing apparatus 104.In addition, by the position with two sensors arm 196A, 196B, to the strain of paddy stalk, do the side change, the paddy stalk of threshing apparatus 104 can be processed depth adjustment to the elongated depths reason side of the fringe end length of the paddy stalk that makes the inside that supplies to threshing apparatus 104.
Figure 10～Figure 12, Figure 15 and shown in Figure 16, equipped the action bars 198 that can carry out the position alter operation of pair of sensors arm 196A, 196B on fringe end sensor 195.Action bars 198 configures on the position of the close Drive Section 102 that is set in fringe end sensor 195.Thus, just can operating operation bar 198 in Drive Section 102, can regulate the paddy stalk of threshing apparatus 104 and process the degree of depth.
As Figure 17, Figure 18 and shown in Figure 22, in reaping part 103, middle nearside divider 121C is configured between groove diameter d a, the db of paddy stalk by left and right packer 172A, 172B in the left and right width of section 127.
By this configuration, by left and right dial in carrying device 124A, 124B with harvested paddy stalk to the paddy stalk during by section 127 conveyance, can prevent that this paddy stalk from crossing middle nearside divider 121C and moving.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 contact; thus; can avoid: the conveyance posture confusion that is caused the paddy stalk by this contact is cause; shelling, easily occur residual in the neat variation by supplying with carrying device 125 fringe front side during to threshing apparatus 104 conveyance with the paddy stalk in the shelling of threshing apparatus 104 is processed, namely the grain rate of recovery is low.
in addition, as mentioned above, left and right 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 offside in the inclination attitude at rear the closer to the center side on the left and right directions of reaping part 103, and become the inclination attitude of lifting on rear portion, in addition, these packers 172A, the posture of 172B is the inclination attitude of lifting on rear portion, thus, in the situation that make reaping part 103 be positioned at operating area, for the middle nearside divider 121C that is flat-hand position or approximate horizontal posture, assistant's side the closer to its conveyance direction, more therefrom nearside divider 121C departs from upward.Thus; can prevent from dialling in paddy stalk nearside divider 121C in the paddy stalk passes through in section 127 to contact of conveyance by section 127 to the paddy stalk by dial in carrying device 124A, the 124B of left and right; low as the grain rate of recovery of cause of the confusion of conveyance posture that as a result, can stop the paddy stalk that causes take this contact.
Figure 24 is the approximate vertical view of the major part of expression 4 ridge harvesting states, and Figure 25 means the approximate vertical view of the major part of 3 ridge harvesting states.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 is away from left and right one side of Drive Section 102 sides) 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 minute careless top 121Aa of left straw-distributing unit 121A and left side.In addition, be arranged in the right part 113Ba of the crawler belt 113B that the crawler belt 113B of the right straw-distributing unit 121B of 103 right-hand end (left and right one sides of reaping part 103 Drive Section 102 sides) of reaping part and right side (Drive Section side) is configured so that on right side under minute careless top 121Ba state that right outside side is protruded a little to car body of right straw-distributing unit 121B, the position of right part 113Ba on the car body left and right directions of minute careless top 121Ba of right straw-distributing unit 121B and the crawler belt 113B on right side is approximately consistent.
That is, crawler belt 113A, the 113B of left and right separates given interval and configures on left and right directions, makes 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 conveyances larger than constituting from L.Thus, can increase the rut spacing of crawler belt 113A, the 113B of left and right, can not cause because 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 with minute careless top 121Aa of left straw-distributing unit 121A by the position that makes its left part 113Aa, the crawler belt 113A in left side can not protrude in left side from careless top 121Aa of this minute to car body.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 the crawler belt 113A in left side splashes mud the generation of the first-class problem of its left-external side standing crops Cx nearby, 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 with minute careless top 121Ba of right straw-distributing unit 121B by the position that makes its right part 113Ba, 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, if set minute careless top 121Ba make right straw-distributing unit 121B by the crop Cb in the operation width between rightmost crop Cb in the operation width of reaping part 103 and the outer crop Cy of the operation width adjacent with this crop Cb, the crawler belt 113B that can prevent right side presses the generation step on the problem that is positioned at its right outside side 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 minute careless top 121Ba from right straw-distributing unit 121B of the crawler belt 113B on right side protrudes to the right outside side of car body, only being required to be the crawler belt 113B that can prevent right side presses and to step on the length that is positioned at the right outside side of car body standing crops Cy nearby and get final product, for example, relation from the plantation interval Sc with crop C, can be set as all lengths such as Lz=1/3*Sc or Lz=1/4*Sc, but preferred Lz≤1/6*Sc.So it is shorter that this protrudes length L z, the crawler belt 113B that more can suppress right side splashes the right outside side of car body standing crops Cy nearby with mud, can prevent from spattering the low of operating efficiency that mud causes.On the contrary, it is longer that this protrudes length L z, left and right crawler belt 113A, and the rut spacing of 113B is longer, can improve the performance wet Tanaka.
That is, when the operation traveling of periphery harvesting or central authorities' harvesting etc., can form crawler belt 113A, the 113B that can prevent left and right and the pressure of standing crops Cx, Cy be stepped on or standing crops Cx, Cy are spattered the specification of comprehensive harvesting of mud.
And the crawler belt 113B that also can configure right side makes, and its right part 113Ba is consistent on left and right directions with minute careless top 121Ba of right straw-distributing unit 121B, perhaps than minute more close body inner side of careless top 121Ba of right straw-distributing unit 121B.In addition, also can configure the crawler belt 113A in left side, make its left part 113Aa than minute more close body inner side of careless top 121Aa of left straw-distributing unit 121A, and, press to step at the crawler belt 113A that can prevent left side and be 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 configure and make its left part 113Aa than minute more close car body left-external side of careless top 121Aa 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 position, make between the harvesting track Cz of the outer crop Cy of the operation width on the right side that in the operation width of careless top 121Ba of its minute by reaping part 103, rightmost crop Cb is adjacent with this crop Cb or crop, in 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 the 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.
namely, when the operation traveling of 4 ridge harvestings, near making because of the front lower place that is positioned at Drive Section 102 and adjusting from minute careless top 121Ba of the high right straw-distributing unit 121B of Drive Section 102 visibilities the right cross side that position makes its rightmost crop Cb by being positioned at the operation width, 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, in the situation that the serious lodging of the C of crop, can be easily and reliably each nearside divider 121A～121B is adjusted position to corresponding on the suitable position of crop C, can efficiency carry out well the paddy stalk of raising apparatus 122A, the 122B of each nearside divider 121A～121B and left and right and prop up.
In addition, due to middle nearside divider 121C 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, 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 left side and import 2 ridge culture thing Cb, Cd in the framework of propping up framework 126B on right side be located at middle nearside divider 121C directly over, across the paddy stalk by on the symmetrical position of section 127, can make becomes the paddy of its left and right object stalk and similarly shortens from the distance of paddy stalk by section 127.
Thus, make left and right prop up framework 126A, 126B in import respectively the paddy stalk of crop C on 2 ridges 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 in framework 126A, 126B that can prevent from importing left and right is unnecessarily elongated by the distance of section 127 from the paddy stalk, any paddy stalk conveyance Efficiency Decreasing of dialling in carrying device 124A, 124B of left and right.In addition; can prevent from producing unnecessary delay in any conveyance of the paddy stalk of dialling in carrying device 124A, 124B of left and right; can prevent: due to the confusion of the conveyance posture of the paddy stalk take this delay as cause; by the neat variation of supplying with carrying device 125 fringe front side during to threshing apparatus 104 conveyance with the paddy stalk; when the shelling of threshing apparatus 104 is processed, shelling occurs easily residual, namely the grain rate of recovery is low.
And, the left side of leftmost crop Ca due to 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: minute careless top 121Ba to right straw-distributing unit 121B carries out the position adjustment, 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 all the time each nearside divider 121A～121C reliably by the above-mentioned correct position with respect to crop C, result, the raising of the workability in the time of can realizing the operation traveling of gathering in 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, with the harvesting track Cz adjustment position of right straw-distributing unit 121B with respect to the crop on right side, make in the situation of careless top 121Ba of its minute by the harvesting track Cz top of the crop on the right side that in the operation width with reaping part 103, rightmost crop Cb is adjacent, middle nearside divider 121C is 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 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 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 the outer crop Cx of the operation width in leftmost crop Ca and the left side adjacent with this crop Ca or crop or centre position roughly.
Namely, when the operation traveling of 3 ridge harvestings, to make because of the front lower place that is positioned at Drive Section 102 from minute careless top 121Ba adjustment position 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 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 in the situation that 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 position to for the suitable position of crop C, can efficiency carry out well the propping up of paddy stalk of raising apparatus 122A, the 122B of each nearside divider 121A～121B and left and right.
In addition, right side due to 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 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 by the distance of section 127 from the paddy stalk by the paddy stalk of the crop Ca in section 127 left side farthest.
Thus, can cross conveyance efficiency while improving by the dialling in carrying device 124A, 124B 3 ridge paddy stalks are dialled in conveyance to the paddy stalk by section 127 of left and right.In addition; can prevent from producing unnecessary delay in any conveyance of the paddy stalk of dialling in carrying device 124A, 124B of left and right; can prevent: due to the confusion of the conveyance posture of the paddy stalk take this delay as cause; by the neat variation of supplying with carrying device 125 fringe front side during to threshing apparatus 104 conveyance with the paddy stalk; when the shelling of threshing apparatus 104 is processed, shelling occurs easily residual, namely the grain rate of recovery is low.
In addition, centre position between crop Cx outside leftmost crop Ca due to left straw-distributing unit 121A by in the operation width and the operation width in left side or the harvesting track Cz of crop or centre position roughly, 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 well its effective object from the minimum left straw-distributing unit 121A of Drive Section 102 visibilities, 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 relationship that is used for meeting above-mentioned 3 nearside divider 121A～121C and crop C, the relation between the Sc of the plantation interval of Sa, Sb and crop C between left and right of 3 nearside divider 121A～121C, can be thought of as the configuration of Sa=Sb=1.75*Sc, the configuration of Sa=Sb ≒ 1.75*Sc, the perhaps configuration of Sa ≒ 1.75*Sc and Sb ≒ 1.75*Sc under Sa＞Sb, perhaps Sa is less than configuration of Sa ≒ 1.75*Sc under Sb and Sb ≒ 1.75*Sc etc.And, when the operation traveling of harvesting 4 ridge culture thing C, preferably make the spacing distance La of left straw-distributing unit 121A and the leftmost crop Ca that is positioned at the horizontal operation width in its right side 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, the posture that nearside divider 121A, the 121B of left and right form minute careless tool 151A, the 151B that make them is the 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, left and right 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 minute careless bar 199C 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 outside side's mode of stretching out to body 101 and be retracted into the body side erect take between posture and carry out the posture conversion.And, be switched 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 minute careless terminal part side 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 the careless top 199a of section of its minute can joltily be linked to and part on the left side on careless tool 151A by the 1st linking part 200.The stretching out end 201a and can joltily be linked on the support component 136 of reaping part 103 by the 2nd linking part 202 of the connecting rod 201 that will stretch out from careless terminal part side of this minute in addition.
The 1st linking part 200 forms by being welded in the L font carriage 203 that parts on the left side on careless tool 151A and parting the connecting pin 204 that minute careless top 199a of section of careless bar 199A can joltily be linked on this carriage 203 on the left side, and makes connecting pin 204 close to the left side that parts careless tool 151A on the left side.
The 2nd linking part 202 is by the carriage 205 that is welded in support component 136, form 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 framework 126A in left side, configuration makes the center side that is positioned at than on the left and right directions of the 1st more close reaping part 103 of linking part 200, 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, at the circular-arc slotted hole 205a that has formed on carriage 205 centered by connecting pin 206, after bolt 208 was inserted this slotted hole 205a, the embedding Compress Spring 209 outside the top side of inserting at this bolt 208, screw togather a pair of nut 210, under the effect of Compress 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 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 formed in the large-scale mode that has been equipped with maintaining body 207, be switched to while 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. in situation, can avoids other object such as the 2nd linking part contact ridge and be out of shape.This is especially effective aspect the distortion that prevents from causing because contacting this concrete block the 2nd linking part 202 in by concrete block etc., forming the field of lower ridge.
In addition, the axle center P that shakes that parts careless bar 199A on the left side at the connecting pin 204 by the 1st linking part 200 and the connecting pin 206De center 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 as 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 can improve with parting careless bar 199A on the left side taking in posture and the effect operation angle while shaking operation between posture the operability that parts careless bar 199A on the left side.
Figure 27 shows that parting careless bar 199A on the left side is switched to the vertical view of the major part of the state of taking in posture.As Figure 13 and shown in Figure 27, parting careless bar 199A on the left side constitutes, take in posture at it, under its minute, careless terminal part 199b was positioned at than the state of the center side on the left and right directions of the more close body 101 of the left end side of reaping part 103, the position of left end side on the car body left and right directions of careless terminal part 199b of its minute and reaping part 103 was approximately consistent.
Thus, part careless bar 199A on the left side, take in posture at it, under careless terminal part 199b of its minute was positioned at than the state of 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, the position of left part 113Aa on the car body left and right directions of the crawler belt 113A in careless terminal part 199b of its minute and left side was approximately consistent.
Namely, be switched to and take in posture by parting careless bar 199A on the left side, a minute careless terminal part 199b who 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 than the body inner side of the more close car body left and right directions of left outside side 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.Result, seize the left outside side's of the more close car body of left outside side of carrying device 131 situation on both sides by the arms compares with minute careless terminal part 199b geometric ratio that parts careless bar 199A on the left side, the left and right width that parts careless bar 199A on the left side and be switched to the integral body of taking in the combine under posture state can be diminished, can improve the taking in property to garage etc.
Part careless bar 199A formation on the left side and make under it takes in posture, its minute, careless terminal part 199b was than the paddy stalk conveyance path 188 more close car body upper sides of supplying with carrying device 125.Thus, even be switched under the state of taking in posture will part careless bar 199A on the left side, can be by supplying with carrying device 125 with the paddy stalk in the situation that do not contact part careless bar 199A on the left side minute careless terminal part 199b to threshing apparatus 104 conveyances.
That is,, even be switched under the state of taking in posture and carry out the operation traveling will part careless bar 199A on the left side, can avoid being parted on the left side by the paddy stalk contact of supplying with 125 conveyances of carrying device minute careless terminal part 199b of careless bar 199A.As a result, can avoid: the neat variation of the fringe front side that causes due to the confusion of the conveyance posture of the paddy stalk take this contact as cause, it is residual when the shelling of threshing apparatus 104 is processed, shelling to occur easily, namely the grain rate of recovery is low.
And, be switched under the state of taking in posture will part careless bar 199A on the left side, due to the integral body that parts 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 outside side of seizing carrying device 131 on both sides by the arms of threshing apparatus 104, therefore carry out on limit, the ridge in 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, more easily carry out the position adjustment of left straw-distributing unit 121A to the crop C on limit, the ridge.As a result, can improve workability on limit, the ridge.
In addition; be the crop C of the less short stalk of the worry of about 65～75cm, lodging for stalk length; be switched to and take in posture and make and part careless bar 199A on the left side and do 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 because parting careless bar 199A on the left side to minute grass effect of the paddy stalk of crop C; as a result, can improve the grain organic efficiency.Particularly effective during this long-grained nonglutinous rice etc. in the easy threshing of harvesting.
As Figure 10～Figure 13 and Figure 15～shown in Figure 17, in minute careless bar 199C in the leading section of reaping part 103C, during being arranged on, setting divide careless tool 151C between connecting member 167, the centre position on the roughly left and right directions of raising apparatus 122A, 122B about being located at.
Thus, thereby minute grass effect of minute careless bar 199C the effect of dialling in of respectively propping up pawl 159A, 159B in guidance field Aa1, the Ab1 of each raising apparatus 122A, 122B by left and right and the paddy stalk of the crop C that becomes to report to the leadship after accomplishing a task from the positive visual angle of car body to raising apparatus 122A, the 122B lodging of another side on car body the place ahead of propping up regional Aa1, Ab1 of each raising apparatus 122A, 122B pass through, separate to the left and right towards prop up regional Aa1, the Ab1 of corresponding raising apparatus 122A, 122B.
Result, the paddy stalk that can avoid the crop C that gathers in is because the car body front side of propping up regional Aa1, Ab1 of the effect of dialling in of respectively propping up pawl 159A, 159B in guidance field Aa1, the Ab1 of each raising apparatus 122A, 122B at each raising apparatus 122A, 122B intersects and entwine from the positive visual angle of car body, can prevent its crop paddy stalk of causing of entwining to prop up efficiency beneath or prop up bad generation.
, as Figure 12, Figure 13, Figure 17, Figure 21 and shown in Figure 22, on 2 ridges that propping up of right side is equipped with on framework 126B, with raising apparatus 122B, form and make it prop up regional Aa2 to be positioned at left side away from Drive Section 102.
Thus, equipped to prop up regional Ab2 and be positioned at as 2 ridges that the mode on the right side of Drive Section side forms and compare with the situation of raising apparatus with propping up on framework 126B of right side, 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.
Raising apparatus 122A, the 122B of left and right so that their the left and right 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.In addition, upper prop up pawl 159A, the 159B that is equipped with of raising apparatus 122A, the 122B of left and right formed the corresponding wider length of propping up regional Aa2, Ab2.
Thus, when the raising apparatus 122A, the 122B that carry out left and right propped up respectively the operation traveling of 4 ridges harvestings of paddy stalk on 2 ridges all the time, the resistance in the time of can preventing the paddy stalk by the regional Aa2 of propping up of left and right correspondence, Ab2 surpassed permissible range.As a result, when carrying out the operation traveling of 4 ridges harvestings, can be smoothly and the paddy stalk that carries out well left and right raising apparatus 122A, 122B prop up.
In addition, owing to making, respectively prop up pawl 159A, 159B and formed the corresponding wider length of propping up regional Aa2, Ab2, can prevent from propping up pawl 159A, 159B and not acting on the dead band of paddy stalk wider formation in propping up regional Aa2, Ab2.As a result, respectively prop up regional Aa2, the Ab2 of raising apparatus 122A, the 122B of left and right have been formed when allowing the width that 2 ridge paddy stalks pass through, can carry out reliably raising apparatus 122A, 122B the propping up the paddy stalk of left and right.
And, no matter be when the operation traveling that gather on 3 ridges or when the operation traveling of 4 ridges harvestings, only make its left and right width W a that props up regional Aa2 of raising apparatus 122A in the left side of having supplied with all the time 2 ridge paddy stalks form the width of propping up of corresponding maximum 2 ridge paddy stalks, and it props up pawl 159A can constitute the corresponding wider length of propping up regional Aa2.
As Figure 11, Figure 14 and Figure 16～shown in Figure 180, the right part that cutting knife driving device 170 is disposed at intermediate member 135 makes the right-hand end that is positioned at reaping part 103.Thus, can prevent that cutting knife driving device 170 is provided to the harvested paddy stalk that causes in the situation of the center side on the left and right directions of reaping part 103 is wound in the undesirable of cutting knife driving device 170, and cutting knife driving device 170 is provided to cause in the situation of 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 be wrapped in undesirable on cutting knife driving device 170.
In addition, supply with carrying device 125 and be disposed on the position that keeps left on reaping part 103 to make and dial in conveyance and supply with conveyances by the paddy stalk of section 127 to the threshing apparatus 104 in car body left side to the paddy stalk because making, 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 and right balance of reaping part 103.
Configured the lid 211 that covers the metallic plate system of cutting knife driving device 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, with the right part that parts careless bar 199B on the right side and jointly be attached to intermediate member 135.
Thus, while having the operation traveling of central authorities harvestings 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, can avoid the right lateral standing crops Cy of this car body to be wound on cutting knife driving device 170.
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 respectively the right part of intermediate member 135 of covering, can improve assembleability.And, part on the right side in the situation of 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, while also having the operation traveling of central authorities harvestings of standing crops Cy in the right outside side of body 101, the lateral surface 213a of body side frame 213 is played as guide surface the standing crops Cy of the right outside side of car body is directed to the right lateral effect of car body.As a result, can with minute careless bar 199B together, stop and be present in the lodging of the right lateral standing crops Cy of body 101 to body inner side.
And, dial in carrying device 124A, 124B in left and right, in the situation that left and right dial in transport mechanism 171A, 171B by rubber system dial in belt 174A, 174B carry out the paddy stalk dial in conveyance act on the harvesting before the paddy stalk, 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, until before gathering in this paddy stalk, this paddy stalk can not dialled in conveyance to the paddy stalk by section 127.In addition, by the operation traveling of this moment, the paddy stalk before 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 state to the state in car body the place ahead from bending, jump out to the car body front side of dialling in transport mechanism 171A, 171B away from left and right, leave the conveyance zone of dialling in transport mechanism 171A, 171B of left and right, be scattering into the place ahead of reaping apparatus 12.
If such phenomenon occurs, 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 again.
If the secondary harvesting of such paddy stalk occurs; 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 conveyance with the paddy stalk; so; when the shelling of threshing apparatus 104 is processed, shelling occurs easily residual, result, easily cause the low of grain organic efficiency.
So, as Figure 17, Figure 18, Figure 22 and shown in 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 constitute them with respect to car body fore-and-aft direction, identical to tiltangleθ a, the θ b of car body left and right directions.In addition, set the posture of dialling in transport mechanism 171A, 171B and supply carrying device 125 of left and right, make angle theta A between the straight line conveyance path 214B that dials in transport mechanism 171B on the straight line conveyance path 214A that dials in transport mechanism 171A in left side and 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 supply carrying device 125.
Set if so the posture of dialling in transport mechanism 171A, 171B of left and right, but by a plurality of moving knife 168 of alignment arrangements above reaping apparatus 123 and dead knife 169, make its linearity ground continuous arrangement on left and right directions, but can make 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.
Thus; dial in carrying device 124A, the 124B that can effectively suppress left and right act on paddy stalk before harvesting by reaping apparatus 123, can effectively suppress to act on the low of the grain organic efficiency that causes of paddy stalk before harvesting because of dial in carrying device 124A, the 124B of left and right.
In addition, can make the paddy stalk that just gathered in by reaping apparatus 123 dial in carrying device 124A, the 124B by left and right promptly to the paddy stalk, by section 127, dial in conveyance, dial in carrying device 124A, the 124B that as a result, can improve left and right dial in conveyance efficiency to the paddy stalk.
As Figure 17 and shown in Figure 22, left and right dial in carrying device 124A, 124B, be equipped with the straight line guide portion 173a, the 173b that extend to the pivot of packer 172A, the 172B of the left and right of correspondence from the end of the left and right of reaping part 103 on guide member 173A, 173B.Each straight line guide portion 173a, 173b form the horizontal linearity of vertical car body fore-and-aft direction.
Thus, straight line guide portion 173a, the 173b of guide member 173A, the 173B of left and right when the operation traveling, act on the front paddy stalk of harvesting, can prevent that this paddy stalk is bent to car body the place ahead.As a result, can avoid the paddy stalk of this press-bending become scattered about the place ahead of reaping apparatus 12 and by secondary, gathered in by the reactivation from the press-bending state when harvesting.
As shown in Figure 12 and Figure 23, supply with carrying device 125 and set its conveyance posture with the conveyance top 125b of section from the mode that the positive visual angle of car body overlaps with Drive Section 102.thus, form reaping part 103 by the specification with 2 framework 4 ridge harvestings, make the position consistency of left part 113Aa on the car body left and right directions of the crawler belt 113A that divides careless top 121Aa and left side of left straw-distributing unit 121A, and the position of right part 113Ba on the car body left and right directions of minute careless top 121Ba of right straw-distributing unit 121B and the crawler belt 113B on right side is roughly consistent, the paddy stalk with respect to the pars intermedia on the left and right directions that is positioned at car body 101 passes through section 127, the conveyance top 125b of section that supplies with carrying device 125 is positioned at can directly receives by on the position of paddy stalk by the dead astern of section 127 of paddy stalk by the paddy stalk after section 127.
That is, can access auxiliary carrying device, the supply conveyance structure that be suitable for the reaping part 103 that forms with 2 framework 4 ridges harvesting specifications of handing-over of paddy stalk not being carried out transfer of dialling between carrying device 124A, 124B and supply carrying device 125 in left and right.
The recess 102a that the conveyance top 125b of section of Drive Section 102 formation permissible feed carrying device 125 on the leading section of the conveyance top 125b of section with supplying with carrying device 125 overlaps in the positive visual angle of car body side plate 115 enters.
Supply with carrying device 125 and increase with respect to dried straight line conveyance path 216 d of the tiltangleθ to the car body left and right directions that seize straight line conveyance path 215 c of the tiltangleθ to the car body left and right directions of transport mechanism 182 on both sides by the arms and lock transport mechanism 183 with respect to the fringe end of car body fore-and-aft direction of the strain of car body fore-and-aft direction, make the recess 102a that the conveyance top 125b of section is entered Drive Section 102.
Thus, compare with the situation that does not form recess 102a on Drive Section 102, can make the nearly Drive Section 102 of conveyance top section side joint of supplying with carrying device 125, can shorten thus the length on the car body fore-and-aft direction of supplying with carrying device 125, 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 action bars 198 that the processing depth adjustment that is equipped with on the support frame 190 of supply carrying device 125 is used is more close Drive Section 102 also, as a result, can more easily carry out the operation of the action bars 198 that the processing depth adjustment is used from Drive Section 102.
And,, if increase to supply with carrying device 125 with respect to tiltangleθ c, the θ d of car body fore-and-aft direction to the car body left and right directions, supply with carrying device 125 and dial in transport mechanism 171A near left sides.Therefore, by what the side contacts left side was done in the strain of the paddy stalk of supplying with carrying device 125 conveyances, dial in transport mechanism 171A, cause the conveyance posture of paddy stalk chaotic.
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 right side to dial in transport mechanism 171B lower.Thus; can prevent from doing the dialling in transport mechanism 171A of side contacts left side and causing the conveyance posture of its paddy stalk chaotic by the strain of the paddy stalk of supplying with carrying device 125 conveyances; can prevent: by this confusion, be cause; by the neat variation of supplying with carrying device 125 fringe front side during to threshing apparatus 104 conveyance with the paddy stalk; when the shelling of threshing apparatus 104 is processed, shelling occurs easily residual, namely the grain organic efficiency is low.
In addition, if the transport mechanism 171A that dials in left side constitutes 2 ridges use, and increase to supply with carrying device 125 with respect to tiltangleθ c, the θ d of car body fore-and-aft direction to the car body left and right directions, left side props up paddy stalk the dialling in transport mechanism 171A and supplying with carrying device 125 with roughly U font conveyance by left side that framework 126A gathers 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 section 127 becoming this, and side is done in the strain of this paddy stalk the tendency of because of centrifugal force, significantly shaking.
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 section 127 from the paddy stalk, between extended part 134 and intermediate member 135, formed the strain that carrying device 124A, 124B transfer to the paddy stalk of supplying with carrying device 125 dialled in that can allow from left and right and done that side is that pass through, transferring path 217 that the front and back width is larger.
Thus; pass through in section 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 is brought by this contact and the neat variation of the fringe front side of the paddy stalk that causes; shelling easily occurs residual in the shelling of threshing apparatus 104 is processed, namely 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 the more close reaping part 103 of section 127.Thus, at the paddy stalk,, by in section 127, the external part of the dried side contacts extended part 134 of strain of the paddy stalk that significantly shakes because of centrifugal force can be prevented more reliably, the low of the grain rate of recovery that causes because of this contact can be prevented more reliably.
Further, the guide member 173A, the 173B that dial in carrying device 124A, 124B that form left and right make and supply with carrying device 125 guiding with by the paddy stalk, by the strain of the paddy stalk of section 127, doing side direction, and, the 173c of guiding terminal section of the guide member 173A in left side is fixed in support component 136, and the 173d of guiding terminal section of the guide member 173B on right side is fixed in the end of stretching out of extended part 134.
Thus, pass through in section 127 at the paddy stalk, even the strain of paddy stalk is done side and is significantly shaken because of centrifugal force, can prevent effectively by the guide member 173B on right side that also it from shaking, the strain of this paddy stalk can be done guide member 173A, 173B rapid strain dried seize in transport mechanism 182 of also reliably transferring to supply carrying device 125 of side by left and right.As a result, can prevent because shifting that the bad paddy stalk that causes stops up or because shifting the low of the bad chaotic grain rate of recovery that causes of conveyance posture that makes the paddy stalk.
As shown in Figure 15, Figure 18 and Figure 22, above linking part 135A, equipped gripper shoe 218 from the external part of extended part 134 to intermediate member 135, it is caught and supports from below from dial in carrying device 124A, the 124B of left and right and transfers to the lower end of the paddy stalk of supplying with carrying device 125.
Thus, can make from dial in carrying device 124A, the 124B of left and right and more easily become neat to the dried side of the strain of the paddy stalk of supplying with carrying device 125 transfers.As a result, the fringe front side of paddy stalk becomes neat, and residual being difficult to of shelling occurs in the shelling of threshing apparatus 104 is processed, and can improve the grain rate of recovery.
Figure 28 means the left surface figure of reaping part 103 of the another way of reaping part 103, and Figure 29 means the front elevation of reaping part 103 of the another way of reaping part 103.As shown in these figures, reaping part 103, by changing left straw-distributing unit 121A, can be equipped minute careless device 219 of driving type between the raising apparatus 122A that parts careless tool 151A and left side on the left side on its left end.

[another way 5 of the 4th embodiment]
In described embodiment, shown that the formed plate body of the resin material that utilizes vinyl chloride carrys out 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, be perhaps the multiple plate body on this.
By changing the overlapping block number of plate body, can change the aperture of relatively identical air quantity, having can be according to the harvesting crops 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 as the advantage of the aperture that is fit to crops condition.
[other different modes]
In the situation that utilize soft vinyl chloride etc. to form shield 421 in free strain ground, shaking under no load condition (not carrying out being come by winnower winnowing machine the state of selection by winnowing) under the state that sorting unit 400B driven by rocking back and forth, (screen box 416 is positioned in 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 forms.Thus, can be when preventing that shield 421 from being attracted by dust discharge fan 404, form gap 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 low weight load, carry out good sorting when preventing from losing for the third time.
[summary of the 4th embodiment]
As mentioned above, in the combine of this embodiment, take following structure as feature.That is:
A kind of threshing apparatus, be equipped with and shake sorting unit below threshing chamber, the below of conveyance upstream side of shaking the handled thing of sorting unit is equipped with winnower winnowing machine, provide sorting wind by this winnower winnowing machine to the dust-exhausting port in the conveyance downstream of handled thing, and be equipped with and can have covered dust-exhausting port and can change in the conveyance downstream of handled thing the curtain-shaped cover member of position, wherein curtain-shaped cover member top is hung on support component, and its below part is formed by a plurality of plate-like portions that can independently shake respectively on width.
According to this feature, in the more situation of the outer stalk bits of sorting discharge machine, due to stronger sorting wind, curtain-shaped cover member rearward retreats significantly, and dust-exhausting port is open significantly.In addition, in 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 a little the sorting air quantity of winnower winnowing machine, moving near dust-exhausting port grain also has bounce-back (takeofing) and easily is discharged from tendency outside machine, according to the 1st feature of the present invention, discharge the outer grain of machine, the parts that are masked are caught and suppressed being discharged to outside machine.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 lower side space of curtain-shaped cover member, perhaps shake or stir a plurality of each plate-like portions, outside gap discharge machine between extended plate-like portion, therefore can carry out well the recovery of grain by curtain-shaped cover member, and reduce by three losses, simultaneously in the situation that do not produce obstruction and can be discharged to well the stalk bits outside machine, can improve the efficiency of separation.
Therefore, form the below part of curtain-shaped cover member by a plurality of plate-like portions by can independently shaking respectively on width, do not hinder the discharge of stalk bits when the more high flow capacity for the treatment of capacity, and during the low discharge that treating capacity is less when turning to etc., even reduce output (sorting air quantity), because each small size plate-like portion is easily rolled or each plate-like portion of adjacency between easily produce gap, therefore when can discharging stalk well, can effectively prevent from losing 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 is connected integratedly on width, the plate-like portion that its below part is blocked about by the institute of a plurality of slits on width is formed.In another preferred embodiment, the plate-like portion of curtain-shaped cover member is consisted 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, although curtain-shaped cover member can be with the vinyl chloride formation of hard, if with soft vinyl chloride, form, be rich in softness, the sidepiece with slit is easily partly rolled, even less air quantity, only have a small amount of stalk bits also can be easy to discharge between slit, can improve the dust discharge performance.
In addition, it is also favourable making curtain-shaped cover member overlap with the plate body more than 2 to form.
Thus, for example, in the situation that heavier crop overlaps the plate body more than 2, 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 in the situation that lighter crop (for example wheat), only need reduce the coincidence piece number of plate body, perhaps do not overlap with 1 plate body, make plate body to roll and to get final product simply.Thus, can reduce lighter stalk and consider the situation that can't roll plate body and can not be discharged to be worth doing.
Industrial practicality
As mentioned above, the present invention can be used in the strain of receiving harvested cereal culm do side by feeding chain keeps, conveyance, and by the shelling tooth, the fringe front side is carried out the head feeding type combined harvester of shelling processing.And the structure of each embodiment, so long as not opposite just can being applied in same combine.
