Next, the detailed structure of the second upper transport apparatus 320 and the power transmission structure to the second upper transport apparatus 320 will be described. Power is transmitted from the small wheel 121 of the second finishing device 120 to the second upper conveying device 320 through the transmission device 150. [
8, 10, and 11, the transmission 150 includes a chain 151, a drive sprocket 152, a driven sprocket 153, and a cover member 154. [ The driving sprocket 152 is fixed to the rotating shaft 163 together with the engraved wheel 121. The follower sprocket 153 is pivoted to the rotation axis 155 which extends rearwardly in parallel with the rotation axis 163 as the right rear side of the drive sprocket 152. The chain 151 is wound on the drive sprocket 152 and the driven sprocket 153.
The chain 151, the drive sprocket 152, and the driven sprocket 153 are covered by a cover member 154 having a substantially rectangular shape. A cylindrical first power transmission pipe 156 having a rotating shaft 163 inserted thereinto is protruded from the lower side of the front side of the cover member 154. The transmission 150 is supported by the second finishing device 120 through the first transmission pipe 156. In addition, a cylindrical second electric power pipe 157 having a rotating shaft 155 inserted therein is provided at the upper rear portion of the cover member 154. The second upper transfer device (320) is supported on the transmission (150) via the second transmission pipe (157).
As shown in Figs. 8 and 10 to 13, the second upper carrying apparatus 320 includes a rotary plate 321, a plurality of (four) tines 322, 322, 322, 322, an upper plate 323, (324). The rotary plate 321 is formed in a substantially disc shape. The rotating shaft 155 is fitted in the central portion of the rotating plate 321 and is fixed to the rotating plate 321. One end portion (bases) 322a, 322b of a tapered tine 322 at a predetermined interval (approximately 90 degrees) in the circumferential direction around the rotation axis 155 at the radially outer end of the rotation plate 321, 322a) are pivotally supported. The base portions 322a and 322a of the tines are projected toward the opposite side of the rotary plate 321 as the axial direction of the support shaft 322c.
The upper plate 323 and the lower plate 324 are plate members having a plate surface larger than the rotary plate 321. The upper plate 323 is disposed above the rotation plate 321 so as to be substantially parallel to the rotation plate 321 when viewed from the side. The lower plate 324 is disposed below the rotating plate 321 so as to be substantially parallel to the rotating plate 321 when viewed from the side. The rotary shaft 155 is inserted into the center of the upper plate 323 and the lower plate 324. The upper plate 323 is fastened to the lower plate 324 by bolts 325 and 325.
A guide member (a first guide member 323a, a second guide member 323b, and a third guide member 323c) for guiding a base portion 322a on one side (upper side) of the tine 322 is provided on the lower surface of the upper plate 323, ) Is formed. The first guide member 323a is a part of the outer circumferential edge (right side) of the upper plate 323 and protrudes in the shape of a band toward the rotating plate 321 so as to follow its outer circumference. The second guide member 323b protrudes in the shape of a strip toward the direction of the rotary plate 321 so as to have a slightly inner circumference than the outer peripheral edge and to have a substantially circular arc shape. The third guide member 323c protrudes from both ends of the second guide member 323b in the direction of the long side toward the direction of the rotating plate 321 in a cylindrical shape. The second guide member 323b and the third guide member 323c are disposed at positions where one base portion 322a of the tine member 322 is in sliding contact with the tine member 322 when the tine member 322 rotates.
Similarly, on the upper surface of the lower plate 324, guide members (a first guide member 324a, a second guide member 324b, and a third guide 324b) for guiding the other base 322a of the tine 322 Member 324c) is formed. The first guide member 324a is a part of the outer peripheral edge (right side) of the lower plate 324 and protrudes in the shape of a band toward the rotating plate 321 so as to follow the outer periphery thereof. The second guide member 324b protrudes in the shape of a band toward the direction of the rotary plate 321 so as to be slightly arc-shaped and slightly arc-shaped than the outer peripheral edge. The third guide member 324c protrudes in a cylindrical shape from both ends of the second guide member 324b in the direction of the long side toward the direction of the rotating plate 321. [ The second guide member 324b and the third guide member 324c are disposed at positions where one base portion 322a of the tine 322 comes into contact with each other when the tine member 322 rotates. The first guide member 324a is connected to the first guide member 323a, the second guide member 324b is connected to the second guide member 323b, and the third guide member 323c is connected to the third guide member 324c in plan view. The width between the first guide members 323a and 324a is set larger than the width of the tines 322 in the axial direction of the rotary shaft 155 so as to pass through the tines 322. [
With this structure, the driving sprocket 152 of the transmission device 150 is rotated by the rotation of the engaging ring 121, and the driven sprocket 153 is rotated through the chain 151 wound around the driving sprocket 152 . The rotary shaft 155 is rotated in accordance with the rotation of the driven sprocket 153. When the rotary shaft 155 of the second upper conveying device 320 rotates, the rotary plate 321 rotates. The tines 322 mounted on the rotary plate 321 are rotated about the support shaft 322c of the tines 322 when the base portions 322a and 322a come into contact with the third guide members 323c and 324c, (321). As a result, the distal end portion 322b of the tine 322 protrudes outward (protrudes in a substantially radial direction) more than the first guide members 323a and 324a. The base portions 322a and 322a of the tines 322 move between the first guide members 323a and 324a and the second guide members 323b and 324b so that the protruded state of the tines 322 is maintained. Thereafter, when the base portions 322a and 322a of the tines 322 are not in contact with the second guide members 323b and 323b, the tip portion 322b of the tines 322 is tilted relative to the first guide members 323a and 324a And the tines 322 are housed without protruding toward the outer side.
It is also possible that the end of the curved portion 173 conveyed to the second upper conveying apparatus 320 is conveyed while being in contact with the edge of the power transmission apparatus 150. That is, the cover member 154 of the transmission device 150 may also be configured to also serve as a guide lever between the curves to be transported.
As described above, the pretensioner 4 of the seventh preparatory combine 1 according to the embodiment of the present invention includes the standing device 40, the finishing device 100, the cutting device 50 and the conveying device 60, The quenching apparatus 100 of the combine 1 of the combine 1 is provided with a pair of right and left quadrants 111 and 112 and a quadrangular belts 113 and 114 and a pair of curved portions 171 A first sub-unit 110 for scraping the first sub-frame 172 and a second sub-unit 170 for scraping one of the three sub-grooves 173 of the three right and left central portions by a single sub- A third finishing apparatus (not shown) for scraping the remaining two troughs 174 and 175 of the three left and right center sides with the apparatus 120, a pair of left and right small-diameter wheels 131 and 132, And a fourth finishing device 140 for scraping two left troughs 176 and 177 with a left and a right pair of right and left roughing wheels 141 and 142 and finishing belts 143 and 144, 2 < / RTI > device 120 and the single < RTI ID = 0.0 > The single engraving wheel and the adjacent engraving wheel 131 of the third engraving device 130 are engaged with each other and the conveying device 60 interlocks with the curved portion 171 A second upper conveying device 320 for conveying the end of the curved portion 173 scraped by the second finishing device 120, A third upper conveying device 330 for conveying the ends of the curved portions 174 and 175 scraped by the third finishing device 130 and a third upper conveying device 330 for conveying the curled portions 176 and 177 scraped by the fourth finishing device 140, And a fourth upper conveying device 340 for conveying the end of the second upper conveying device 320 to the second upper conveying device 320. The fourth upper conveying device 340 is configured to convey the power from the third interlace device 130 to the second upper conveyance device 320 through the second interlace device 120 .
Accordingly, the power transmission structure to the second upper transport apparatus 320 is installed above the second finishing apparatus 120. That is, in the vicinity of the confluence portion where the grooves of the respective tributaries during conveyance by the conveyance device 60 are joined together, specifically, the vicinity of the lower conveyance device 200 In the vicinity of the confluence portion 182 where the bottom side of the curved portion during conveyance joins or near the confluence portion 192 where the ends of the curved portion during conveyance by the upper conveyance device 300 are joined. Therefore, it is possible to simplify the structure in the vicinity of the merging portion and to suppress clogging of the merging portion in the vicinity of the merging portion. In addition, the power transmission structure can be simplified in the second upper conveying device 320.
Since the upper portion of the one concave section 173 is conveyed, the power required for driving the second upper conveying apparatus 320 is minimized. That is, the second upper transfer device 320 can be sufficiently driven even when the power is transmitted from the small gear wheel 131 through the small gear wheel 121 and the transmission device 150 as in the present embodiment.
The finishing apparatus 100 may further include a single finishing wheel 121 of the second finishing apparatus 120 and a plurality of finishing wheels 130 of the third finishing apparatus 130 engaged with the single finishing wheel 121. [ 112, 132, 141, and 142. In this case, the thickness of the ring gear 131 is set larger than the thickness of the other engraved wheels 111, 112, 132, 141,
This makes it difficult for the single engaging wheel of the second interleaving device and the engraving wheel of the third interleaving device to be disengaged from each other. That is, in the case where there is a pair of the small-diameter wheels 131 and 132 in the sintering apparatus 100 like the third small-size unit 130, when a pair of small- The symmetry in the left and right is distorted, so that the power transmission from one of the smaller-diameter wheels 131 to the other of the smaller-diameter wheels 132 does not occur. On the other hand, in the case where there is only a single minor wheel 121 like the second finishing apparatus 120, when a narrow gap is conveyed while being conveyed, even a single minor wheel 121 is distorted. However, There is a possibility that the meshing is released and the power transmission from the meshing wheel 131 to the single meshing wheel may be hindered. However, since the single engaging wheel 121 and the engaging wheel 131 are thicker than the other engaging wheels 111, 112, 132, 141 and 142, the engaging becomes difficult to be released. Therefore, it is possible to reliably transmit the power from the small wheel 130 of the third prime mover 130 to the single small wheel 121 of the second prime mover 120, and further to the second upper conveyor 320 It can be reliably transmitted from the third interleaving device 130 through the second interleaving device 120. [
The quadrature detector 100 may further include a pair of right and left quadrature wheels 131 and 132 of the first quadrant wheel 121 and the third quadrant 130 of the second quadrature detector 120, Are arranged at positions higher than the pair of right and left small wheel 111 and 112 and the pair of left and right small wheel 141 and 141 of the first sub-unit 110 of the first sub-
The left and right pair of right and left small wheels 131 and 132 of the first small-diameter driving unit 121 and the right small-diameter unit 130 of the third small- It is possible to avoid the interference with the pair of the small wheels 111 and 112 and narrow the gap therebetween. A pair of left and right pair of right and left small wheel rings 131 and 132 and a pair of left and right pair of right and left pair of right and left small wheel rings 131 and 132 of the third small- It is possible to avoid the interference with the small wheel 141, At the same time, in the finishing apparatus 100, the single finishing belt 122 of the second finishing apparatus 120 and the pair of right finishing belts 133 and 134 of the third finishing apparatus 130 are disposed in the first finishing apparatus The pair of right and left narrowing belts 113 and 114 and the pair of right and left narrowing belts 143 and 144 of the fourth finishing unit 140 are positioned at a higher position. Accordingly, as in the above-described case, the single finer belt 122 of the second finishing apparatus 120 and the pair of right and left finer belts 133 and 134 of the third finishing apparatus 130 and the first finishing apparatus 110 The pair of right and left narrowing belts 113 and 114 can be prevented from interfering with each other. A pair of right and left pairs of the right and left quenching belts 133 and 134 and the pair of left quadrants of the fourth quadrant unit 140 of the third quenching unit 130 and the single quenching belt 122 of the second quenching unit 120, It is possible to avoid the interference with the quenching belts 143, Therefore, it is possible to narrow the spacing of the adjacent interleaving devices in the left and right directions, and to compact the mounting portion of the interleaving device, that is, the preheating portion 4.
The right side of the third finishing device 130 and the second finishing device 120 are disposed side by side in the left and right sides of one of the adjacent finishing wheels 131 of the third finishing device 130, So that power is transmitted to the single small wheel 121 of the vehicle. Accordingly, the motive power is equally allocated to the two small-diameter wheels 121 and 132 arranged side by side on both right and left sides of the small-diameter wheel 131 in the small- Therefore, the loads on the respective engraving wheels 121, 131, and 132 are dispersed, so that the failure rate of the second and third finishing devices 120 and 130 can be reduced.
It is also possible to arrange the engaging wheel 121 of the second engraving device 120 and the right engaging wheel 131 of the third engraving device 130 side by side so as to engage with each other, To drive the second lower conveying device (220). As a result, in the vicinity of the confluence portion where the grooves of the respective coarse fractions during conveyance by the conveyor device 60 are joined together, specifically, in the vicinity of the lower conveyor device 200 do not need to be provided in the vicinity of the confluence portion 182 where the bottom side of the curved portion during conveyance joins or in the vicinity of the confluence portion 192 where the ends of the curved portion conveyed by the upper conveyance device 300 join. Therefore, it is possible to simplify the structure in the vicinity of the merging portion and to suppress clogging of the merging portion in the vicinity of the merging portion. In addition, a power transmission device such as a drive shaft for transmitting power to the second lower conveying device 220 is unnecessary. That is, the power transmission structure to the second lower conveying device 220 can be simplified, and the number of parts can be reduced.
In the present embodiment, the squeezing apparatus 100 scrapes and feeds back three pairs of right and left curved portions on the right and left sides to the left and right sides. However, the second and third sub- The second upper transporting device 320 and the third upper transporting device 330 are exchanged between the second lower transporting device 220 and the third lower transporting device 230, It is also possible to divide the curved portion of the three right and left central portions into two for the right side and one for the left side so as to be raked and conveyed to the rear side.
Then, a plurality of right and left fine pulleys and a plurality of finishing devices having a finer belt are arranged side by side to constitute an even finishing cut portion, and a finishing device having a single finishing wheel and a finishing belt is added to the finishing portion for even finishing It is possible to easily construct a power transmission mechanism for a single interrupter by merely interlocking with a pair of right and left small wheels in a case where a single small wheel is interdigitated with each other. Further, in the case of a configuration in which power is transmitted to a lower conveying device for conveying a base of a single piece scraped from a single engraving wheel engaged with each other or to an upper conveying device for conveying the end of a thread, The power transmission structure can be simplified and facilitated.
Next, the structure of the third upper transport apparatus 330 will be described in detail.
The third upper conveying apparatus 330 includes a conveying chain 331, a plurality of tines 332, 332, ..., an upper plate 333, a lower plate 334, an auxiliary plate 335, a drive sprocket 336, 337, a tension sprocket 338, and a tension adjusting mechanism 350. One ends (bases 332a and 332a) of the tines 332, 332, ... in a substantially hexagonal shape are pivotally supported at the outer peripheral ends of the transport chain 331 at predetermined intervals. The base portions 332a and 332a of each tine are projected toward the opposite side of the transport chain 331 as the axial direction of the support shaft 332c.
The upper plate 333 is disposed above the transport chain 331 so as to be substantially parallel to the transport chain 331 when viewed from the side. The lower plate 334 is a lower portion of the conveying chain 331 and is disposed so as to be substantially parallel with the conveying chain 331 when viewed from the side. The upper plate 333 is fastened to the lower plate 334 by a bolt nut 339 or the like. The auxiliary plate 335 is extended from the rear of the lower plate 334 to the right.

[
The first guide portion 360b guides the curved portions 171, 172 and 173 conveyed to the first upper conveying device 310 (including the end conveying device 90) to the joining portion 193. The first guide portion 360b is arranged so as to be opposed to the first upper transport device 310 substantially in parallel with the first upper transport device 310 when viewed in plan.
The second guide portion 360c guides the interstices 174, 175, 176 and 177 being conveyed to the fourth upper conveying device 340 to the confluence portion 193.

In the case of the preamble portion of the conventional combine, in the case where the cutting portion has a plurality of joining portions in the lower conveying device, it is necessary to operate the clogging releasing means for each joining portion by providing the joining releasing means at each joining portion. Therefore, when the concave curtains are simultaneously clogged in a plurality of confluent portions, the operator has to operate the clogging releasing means for each confluent portion in order to remove the curtains, which is disadvantageous in that the operation becomes cumbersome. Thus, it is possible to easily remove the clogged portion in the merging portion of the lower conveying device, and to improve the maintenance and the water retention.
The upper frame 545, the intermediate frame 546, the lower frame 547, and the clogging releasing means 600 of the fourth lower conveying apparatus 240 will be described in detail.

The lower end of the disengaging pulley shaft 630 abuts against the lower bracket 612. The disengaging pulley shaft 630 is fixed to the lower bracket 612 by a bolt 632 threaded into the through hole 612a from below the lower bracket 612. [
The floating pulley shaft 640 is a turning point of the floating pulley 245. The floating pulley shaft 640 is inserted through the through hole 611c of the upper bracket 611, the floating pulley 245, and the spacer 641 in this order. The lower end of the floating pulley shaft 640 abuts the lower bracket 612. The floating pulley shaft 640 is fixed to the lower bracket 612 by a bolt 642 threaded into the through hole 612b from below the lower bracket 612. [

That is, the upper bracket 611 and the lower bracket 612 are connected by the temporary pulley shaft 630 and the floating pulley shaft 640.
The regulating member 652 is formed by folding and folding in a L-shape when viewed in a plan view (FIG. 14). The regulating member 652 is erected at the rear end of the upper frame 545 and the upper frame plate 548. [ One of the bent portions of the regulating member 652 extends in a forward and backward direction that is substantially parallel to a line connecting the axial center of the pivot shaft 620 and the axial center of the floating pulley shaft 640 and is a surface abutting against the protruding portion 651b . The other bent portion of the regulating member 652 extends in the oblique left and right direction and is a surface that abuts the front surface of the grip portion 651a. As described above, the two bent portions of the regulating member 652 respectively serve as a stopper of the operation lever 651 by abutting against the projecting portion 651b or the grip portion 651a of the operation lever 651, respectively. The regulating member 652 can be used as a connecting member for connecting the upper frame 545 and the upper frame plate 548 to members such as another frame.
The pin 653 restricts rotation of the operation lever 651. The pin 653 is inserted into a pin hole 545a formed at the rear end of the upper frame 545. [ The distal end (lower end) of the pin 653 inserted into the pin hole 545a protrudes downward from the upper frame 545. [
Hereinafter, an operation mode of the clogging release means 600 configured as described above will be described.
First, a description will be given of a case in which the cutting operation is carried out by the pre-loading section 4.
14, the operation lever 651 is rotated in the clockwise direction when viewed from the plane with respect to the bracket 610, and the projections (not shown) of the operation lever 651 651b are engaged with the regulating member 652 from the right side. In this state, the pressing force is applied to the bracket 610 in the clockwise direction when viewed from the plane by the tension of the conveying chain 241. However, since the operation lever 651 is locked to the regulating member 652, the bracket 610 does not rotate in the clockwise direction when viewed from the plane, but rotates counterclockwise by a predetermined amount with respect to the upper frame 545 Position.
In this case, the separating pulley 244 is held at a position close to the merging portion 183 and the merging portion 181. Hereinafter, the position of the discrete pulley 244 is defined as a working position.
When the bracket 610 is held at a position projected to the right by a predetermined amount relative to the upper frame 545, that is, when the temporary pulley 244 is held in the working position, And the portion projecting downward from the pin hole 545a of the pin 653 abuts against the operation lever 651 from the rear side. That is, the rotation of the operation lever 651 in the counterclockwise direction is restricted by the pin 653. Thus, even when the tension of the conveying chain 241 or other external force is applied to the clog loosening means 600, the separating pulley 244 Can be kept in the working position.
Next, a description will be made of a case where the groove is clogged by the joining portion 183 or joining portion 181, and the groove is removed.
17, the operator first moves from the upper frame 545 to the pin 653 after moving to the left side room of the preloading section 4, when the clogged section between the merging section 183 and the merging section 181 is removed, ). As a result, the restriction of the rotation of the operation lever 651 is released, and the operation lever 651 becomes rotatable in the counterclockwise direction.
Next, the operator grips the grip portion 651a of the operation lever 651 from the left side of the preload portion 4 and rotates the operation lever 651 counterclockwise when viewed from the plane. As a result, the engagement between the projecting portion 651b of the operation lever 651 and the regulating member 652 is released. That is, the bracket 610 becomes rotatable in the clockwise direction when viewed from the plane.
18, the operator grips the grip 651a of the operation lever 651 while holding the operation lever 651 at the maximum rotation within the range limited by the slot 651d, (651) is pulled toward the left side of the preload section (4). Accordingly, the bracket 610 connected to the operation lever 651 through the disengaging pulley shaft 630 rotates in the clockwise direction when viewed from the plane around the rotation axis 620. [ When the bracket 610 is rotated in the clockwise direction when viewed from the plane as described above, the turning point shaft 620 serving as the turning point of the bracket 610 is positioned on the upstream side of the joining portion 181 and the joining portion 183 The separating pulley 244 is separated from the merging portion 183 and the merging portion 181. Therefore, Hereinafter, the position of the intermittent pulley 244 is defined as an intermittent position.
The space between the transport chain 241 and the transport chain 231 and the space between the transport chain 241 and the transfer chain 241 in the confluence portion 181 in the merging portion 183, The space between the chains 211 is wider than in the case where the separating pulley 244 is in the working position. This makes it possible to easily remove the clogged portion between the confluent portion 183 and the confluent portion 181.
Next, a description will be given of a case in which the clogged portion 183 or the confluent portion 181 is closed and then the position of the separating pulley 244 is returned to the working position.
When the position of the disengaging pulley 244 is returned to the work position, the operator holds the operation lever 651 while grasping the operation lever 651a of the operation lever 651 and pushes the operation lever 651 toward the right side of the preload section 4. Thus, the bracket 610 connected to the operating lever 651 is rotated in the counterclockwise direction when viewed from the plane through the disengaging pulley shaft 630. [ The operator rotates the bracket 610 until the intermittent pulley 244 returns to the working position.
Next, the operator rotates the operating lever 651 in the clockwise direction when viewed from the plane to the maximum extent within the range limited by the slot 651d. As a result, the projecting portion 651b of the operation lever 651 and the regulating member 652 are engaged.
Lastly, the pin 653 is inserted into the pin hole 545a of the upper frame 545 to restrict the rotation of the operation lever 651 in the counterclockwise direction. Thus, the separating pulley 244 can be held at the working position again.
As described above, the preliminary loading section 4 of the combine 1 according to the embodiment of the present invention includes the standing device 40, the finishing device 100, the cutting device 50, the lower conveying device 200, The lower conveying apparatus 200 of the preamplifier 4 of the combine 1 having the apparatus 300 and the vertical conveying apparatus 70 is configured so that one or two troughs of the center left side are connected to the merging section 181 , A second lower conveying device 220 for conveying one or two troughs of the center right side to the merging portion 182, and a third lower conveying device 220 for conveying one or two A fourth lower conveying device 240 for conveying the curved portion from the third lower conveying device 230 joined to the curved portion of the curved portion 181 to the merging portion 183, And the fourth lower conveying device 240 joined by the merging portion 183 and the curved portion from the second lower conveying device 220 merged into the merging portion 182 are connected to the upper conveying device 70 And the fourth lower conveying device 240 includes a merging portion 181 and an intermittent pulley 244 disposed to face the merging portion 183 And an operation for bringing the position of the separating pulley 244 close to the merging portion 181 and the merging portion 183 is carried out by the operation of bringing the position of the separating pulley 244 close to the merging portion 181 and the merging portion 183 And a clog loosening means (600) capable of changing the position between the joining portion (181) and the joining portion (183).
The distance between the merging portion 181 and the separating pulley 244 and the distance between the merging portion 183 and the separating pulley 244 are At the same time. Therefore, it is possible to make the state of being able to remove the clogged portion between the confluent portion 181 and the confluent portion 183 by one operation of changing the intermittent pulley 244 to the intermittent position, and the confluent portion 181 and It is possible to provide a simple structure without providing any clogging releasing means for each of the merging portions 183, and to improve maintenance and water retention.
The clogging releasing means 600 is rotatably provided with respect to the body of the preloading section 4 and includes a bracket 610 for rotatably supporting the intermittent pulley 244 and a bracket 610 And a holding mechanism 650 for holding the separating pulley 244 at the working position so that the turning point of the bracket 610 (the turning point shaft 620) (183).
With such a configuration, when the bracket 610 is rotated in the direction in which the bracket 610 is separated from the merging portion 181 and the merging portion 183 by disposing the turning point shaft 620 on the upstream side of the merging portion 183 The distance between the fourth lower conveyance unit 240 and the first lower conveyance unit 210 and the distance between the fourth lower conveyance unit 240 and the third lower conveyance unit 230 are smaller than the confluence unit 183, (181). Therefore, since it is located on the downstream side of the joining portion 183 in the conveying direction, it is easy to remove the clogged portion in the joining portion 181, which is likely to be clogged with a relatively large number of gaps, and maintenance and water retention can be improved.
The fourth lower conveyance device 240 is disposed on the opposite side to the operation section 9 disposed on the combine 1, that is, on the left side of the combine 1.
With this configuration, the fourth lower conveyor apparatus 240 is disposed on the side opposite to the operation section 9, whereby the clogging release means can be operated from the side opposite to the operation section 9. [ Accordingly, when the clogging releasing means is operated, the operation section 9 is not disturbed, and maintenance and water retention can be improved.
