  Next, the threshing device 3 and the sorting device 4 will be described in more detail. In the following description, threshing will be described as “threshing C”, grain as “grain G”, and sawdust as “sawdust S”.

  FIG. 3 shows the threshing device 3 and the sorting device 4. FIG. 4 shows the structure of the sorting device 4. FIG. 5 shows a situation where the sorting device 4 is sorting the grains G. In the figure, the direction in which the grain G which is the threshing C and the sawdust S, etc. moves is shown. In the figure, the direction of the wind flow by the fan 421 is shown.

  First, the threshing apparatus 3 will be described.

  As described above, the threshing device 3 includes the handling cylinder 31 and the receiving net 32. The handling drum 31 threshs the cereal by rotating. Moreover, the handling drum 31 conveys the cereal by rotating. The receiving net 32 supports the cereals conveyed by the handling cylinder 31 and drops the cereal C to the sorting device 4.

  The handling cylinder 31 mainly includes a center shaft 311, an impeller 312, and a tooth bar 313. In the main barrel 31, an impeller 312 is disposed at the front end portion of the center shaft 311, and a plurality of tooth bars 313 are disposed behind the impeller 312 around the center shaft 311.

  The center shaft 311 is a long and straight structure. The center shaft 311 supports the impeller 312 and the tooth bar 313. The center shaft 311 supports the impeller 312 at the front end portion, and supports the plurality of tooth bars 313 from the center portion to the rear end portion. The center shaft 311 has a front end portion and a rear end portion that are rotatably supported by the case 314.

  The impeller 312 is a structure in which a spiral blade 312b is formed. The impeller 312 scrapes the cereal that has been fed by the rotor 25. In other words, the impeller 312 rotates to take in the cereals that have been fed by the rotor 25 and send them back. The impeller 312 is not limited to the structure including the spiral blade 312b, and may be a structure including a plurality of blades.

  The tooth bar 313 is a structure in which a plurality of handle teeth 313t are attached in parallel at predetermined intervals. The tooth bar 313 threshs the cereal meal sent out by the impeller 312. That is, when the tooth bar 313 rotates, the tooth cereal sent out by the impeller 312 is swallowed and the cereal C is dropped. The tooth bar 313 is not limited to a structure including a plurality of handle teeth 313t, and may be a structure that supports a helical rotor. Further, instead of forming a cylindrical rotating body by the plurality of tooth bars 313, a structure in which a plurality of handle teeth 313t are provided on one cylindrical member may be used.

  The receiving network 32 is mainly composed of a network body 321. In the receiving net 32, the net body 321 is arranged so as to cover the lower side of the rotating body constituted by the plurality of tooth bars 313.

  The net 321 is a structure in which a plurality of wires 321w are stretched in parallel at a predetermined interval. The net body 321 supports the culm that is swallowed by the tooth bar 313. Moreover, the net body 321 drops the cereal C from the gap into the sorting device 4. Note that the left end and the right end of the net 321 are supported by the case 314 in a detachable manner.

  Next, the sorting device 4 will be described.

  As described above, the sorting device 4 includes the swing device 41 and the blower device 42. The swinging device 41 sorts the grain G by sifting the cereal cereal C. The blower 42 sorts the grain G by blowing away the sawdust S and the like contained in the cereal C.

  The oscillating device 41 mainly includes a feed pan 411, a chaff sheave 412, a stroller 413, and a separator 414. In the present swinging device 41, a chaff sheave 412 is disposed behind the feed pan 411, and a stroller 413 is disposed behind the chaff sheave 412. Further, a separator 414 is disposed above the chaff sheave 412.

  The feed pan 411 is a structure that is widely flat. The feed pan 411 receives the threshing C that has fallen from the receiving net 32. Further, the feed pan 411 swings back and forth, and moves the cereal C on the feed pan 411 while moving backward. At this time, the threshing C is spread evenly in the left-right direction by the fins 411f attached obliquely.

  The chaff sheave 412 is a structure in which a plurality of sheave plates 412p are attached in parallel at predetermined intervals. The chaff sheave 412 filters the cereal C that has been sent from the feed pan 411. That is, the chaff sheave 412 is swung back and forth, and sifts the cereal crop C sent from the feed pan 411. Thereby, the sawdust etc. S mixed in the cereal C can be lifted and separated from the grain G. In this way, the chaff sheave 412 sorts the grains G from the cereals C (referred to as “fine sorting”). In addition, after the fine selection, the cereal C (only the grain G) is passed through the sieve net 415 and then guided to the first flow grain plate 431 and falls to the top 43. Further, the threshing C remaining on the chaff sheave 412 moves rearward and is sent to the stroller 413.

  The Strollac 413 is a structure in which a plurality of rack plates 413p are attached in parallel at predetermined intervals. The Strollac 413 filters the cereal cereal C sent from the chaff sheave 412. That is, the Strollac 413 swings back and forth, and sifts the cereals C sent from the chaff sheave 412. Thereby, relatively large sawdust S and the like mixed in the cereal C can be supported and separated from the grain G. In this way, the Strollac 413 performs sorting (referred to as “fine sorting”) of the grain G from the cereal C. In addition, the cereal C after the fine selection (the grain G and a small number of small swarf S or the like S) is guided to the second cereal plate 441 and falls to the second bowl 44. Further, the threshing C remaining on the Strollac 413 moves rearward and is discharged to the outside.

  The separator 414 is a structure in which countless holes are provided in a wide flat plate material. The separator 414 filters the cereal C that has fallen from the receiving net 32. That is, the separator 414 swings back and forth to screen the cereal C that has fallen from the receiving net 32. Thereby, comparatively large sawdust S etc. mixed in the cereal C can be caught and separated from the remaining cereal C. Thus, the separator 414 removes relatively large swarf and the like S from the cereal crop C (referred to as “rough sorting”). Incidentally, the cereal C after the coarse selection (the grain G and a large number of small sawdusts S) falls directly to the chaff sheave 412. Further, the cereal cereal C remaining on the separator 414 moves rearward and falls to the stroller 413.

  Then, the chaff sheave 412 sifts the cereal C that has fallen from the separator 414 together with the cereal C sent from the feed pan 411. As described above, the cereal C after the fine sorting (only the grain G) passes through the sieve net 415 and is then guided to the first flow grain plate 431 and falls down to the top 43. Further, the threshing C remaining on the chaff sheave 412 moves rearward and is sent to the stroller 413.

  In addition, the Strollac 413 sifts the cereal C that has fallen from the separator 414 together with the cereal C sent from the chaff sheave 412. As described above, the cereal C after the fine sorting (the grain G and a small number of small swarf S or the like S) is guided by the second cereal board 441 and falls to the second bowl 44. Further, the threshing C remaining on the Strollac 413 moves rearward and is discharged to the outside.

  The blower 42 is mainly composed of a fan 421 and a fan case 422. In the air blower 42, a fan 421 is disposed below the feed pan 411, and a fan case 422 is disposed so as to cover the fan 421.

  The fan 421 is a structure in which a plurality of fan plates 421p are attached at predetermined angles. The fan 421 sends wind toward the chaff sheave 412 and the stroller 413, and blows off the dust S and the like. In other words, the fan 421 blows away the sawdust etc. S on the chaff sheave 412 and the sawdust S dropped from the chaff sheave 412 by rotating and sending out the wind. Further, the fan 421 rotates to send out the wind, thereby blowing away the waste dust S on the Strollac 413 and the waste S falling from the Strollac 413. Thereby, comparatively small swarf etc. S mixed in the cereal C can be blown away and separated from the grain G. Thus, the fan 421 selects the grain G from the cereal cereal C. In addition, the cereal C after sorting (only the grain G) is guided to the first cereal board 431 and falls to the most ridge 43. Alternatively, the cereal C after sorting (the grain G and a small number of small swarf S or the like S) is guided by the second cereal board 441 and falls to the second bowl 44.

  The fan case 422 is a structure formed by bending a plate material. The fan case 422 covers the fan 421 and guides the wind sent out by the fan 421 in a predetermined direction. More specifically, the fan case 422 branches the wind sent out by the fan 421 into four, and guides them in a predetermined direction.

  Here, the direction in which the wind flows will be described in detail.

  The air blower 42 includes an upper guide 423. The upper guide 423 branches the wind sent out by the fan 421 upward, and causes one to be along the upper surface of the chaff sheave 412 and the other to be along the lower surface of the chaff sheave 412. Thereby, the sawdust S etc. on the chaff sheave 412 and the stroller 413 can be blown off. Further, sawdust and the like S that have fallen from the chaff sheave 412 and the stroller 413 can be blown off. Furthermore, the sawdust etc. S on the sieve net 415 can be blown off.

  The air blowing device 42 includes a lower guide 424. The lower guide 424 branches the wind sent out backward by the fan 421, directs one to the chaff sheave 412 through the sieve net 415, and directs the other along the first cereal plate 431 to the strolac 413. Thereby, the sawdust S etc. on the chaff sheave 412 and the stroller 413 can be blown off. Further, sawdust and the like S that have fallen from the chaff sheave 412 and the stroller 413 can be blown off. Furthermore, the sawdust etc. S on the sieve net 415 can be blown off. The first cereal plate 431 is installed from the first basket 43 provided below the chaff sheave 412 toward the stroller 413. For this reason, the wind which flows along the 1st flow grain board 431 is gradually strengthened, and reaches | attains the stroll back 413 (refer * mark of FIG. 7).

  The characteristic points of the sorting device 4 according to this embodiment will be described below.

  In the combine 100, the feed pan 411 is disposed below the front side of the handling cylinder 31 (see FIGS. 3 and 5). For this reason, the cereal C falling on the feed pan 411 is considered to be less contaminated with S and the like S. This is due to the fact that the cereal buds are not squeezed so much at the front side of the barrel 31. Such characteristics also apply to other common combines.

  On the other hand, the separator 414 is disposed from the lower center of the handling cylinder 31 to the lower rear part (see FIGS. 3 and 5). For this reason, it is assumed that the cereal C falling on the separator 414 is often mixed with S or the like S. This is due to the fact that the cereals are considerably sown at the stage from the center to the rear side of the barrel 31. Such characteristics are also applicable to other general combines.

  In addition, the separator 414 is arranged on the rear upper side of the feed pan 411 (see FIGS. 3, 4, and 5). Specifically, the separator 414 is attached behind the rear end portion of the feed pan 411 (see arrow B in FIG. 5) and above the upper surface portion of the feed pan 411 (FIG. 5). Arrow H). Therefore, in the present swinging device 41, a passage P through which the shed grain C passes from the feed pan 411 to the chaff sheave 413 is configured even though the separator 414 is disposed above the chaff sheave 412.

  Thus, the sorting device 4 has a structure in which the chaff sheave 412 is disposed behind the feed pan 411 and the separator 414 is disposed above the chaff sheave 412. The separator 414 is disposed on the rear upper side of the feed pan 411, thereby forming a passage P through which the grain removal C passes from the feed pan 411 to the chaff sheave 412. As a result, the cereal C that falls on the feed pan 411 (the cereal C with less mixing of sawdust and the like S) can be sent to the chaff sheave 412 without being subjected to rough sorting by the separator 414. The falling cereal C (the cereal C having a large amount of S, such as sawdust) can be sent to the chaff sheave 412 after being roughly sorted by the separator 414. Therefore, it is possible to improve the grain sorting speed while maintaining high grain G sorting accuracy.

  In the present swing device 41, the separator 414 has a structure in which an infinite number of square holes are provided in a wide flat plate material (referring to a so-called punching plate: see FIG. 6A), but the present invention is not limited to this. Absent. For example, the structure (refer FIG. 6 (B), FIG.6 (C), FIG.6 (D)) which provided the countless round hole, the triangular hole, and the rhombus hole may be sufficient. Further, a structure in which a metal wire is knitted (refers to a so-called crimp net or the like) may be used.

  Next, other characteristic points of the sorting device 4 according to this embodiment will be described.

  FIG. 6 shows the structure of the separator 414. FIG. 7 shows the attachment position of the sieve line 414S.

  In the present sorting apparatus 4, the separator 414 has a structure in which a sieve wire 414S is installed at the rear part thereof.

  The sieve line 414S is a structure in which a plurality of spikes 414s are formed in parallel at a predetermined interval. The sieving line 414S filters the cereal crop C sent from the mesh part 414M of the separator 414. That is, the sieving line 414S swings back and forth, thereby further sifting out the cereal crop C sent from the mesh part 414M of the separator 414. Thereby, comparatively large sawdust S etc. mixed in the cereal C can be caught and separated from the remaining cereal C. Thus, the sieve line 414S removes relatively large swarf and the like S from the cereal crop C (referred to as "rough sorting"). Incidentally, the cereal C after the coarse selection (the grain G and a large number of small sawdusts S) falls directly to the chaff sheave 412. Further, the threshing C remaining on the sieve line 414S moves rearward and falls to the stroller 413.

  Thus, the separator 414 has a structure in which the sieve wire 414S is installed at the rear part thereof. As a result, for the cereal C (the cereal C in which large amounts of S and the like S are mixed) sent from the mesh part 414M of the separator 414, rough selection can be performed using the sieve line 414S. Therefore, it becomes possible to improve the selection accuracy of the grain G.

  In the sorting apparatus 4, the sieve line 414S is detachable, but the present invention is not limited to this. For example, a portion corresponding to the sieve line 414S may be integrally formed.

  In addition, the sieving line 414S of the sorting device 4 is fixed to the mesh part 414M of the separator 414 on the front side (see arrow F in FIG. 7) of the first cereal plate 431. And as for the sieve line 414S, the spike 414s is extended in the back side rather than the terminal 431e of the 1st flow grain board 431 (refer arrow B of FIG. 7). In other words, the sieve line 414 </ b> S is arranged so that the spike 414 s intersects the perpendicular line L passing through the end 431 e of the first flow grain plate 431.

  In this way, the sieve line 414S is installed such that only the tip portion of the spike 414s protrudes rearward from the end 431e of the first flow grain plate 431. Thereby, among the cereal C sent from the net part 414M of the separator 414, the cereal C containing relatively small swarf etc. S falls to the chaff sheave 412 and the relatively larger swarf etc. S About the cereal C containing, it falls to the Strollac 413. Therefore, it becomes possible to improve the selection accuracy of the grain G.

  Furthermore, other characteristic points of the sorting device 4 according to the present embodiment will be described.

  FIG. 8 shows a structure for attaching the separator 414. FIG. 9 shows each state when the attachment position of the separator 414 is changed.

  In the sorting device 4, the feed pan 411, the chaff sheave 412, and the stroller 413 are supported by the side frame 416. The separator 414 is also supported by the side frame 416.

  The side frame 416 is disposed in parallel to the front-rear direction of the combine 100. The side frame 416 is provided with a plurality of bolt holes 416b along the front-rear direction, and a bracket 417 is attached using the bolt holes 416b and the rivet bolts 416B (FIGS. 8B and 8). (See (C)). That is, the bracket 417 is fixed to the side frame 416.

  The bracket 417 is a structure generally called “L-shaped angle”. The bracket 417 is fixed in a state where one plane is in contact with the side frame 416, so that the other plane 417p becomes horizontal. The bracket 417 is provided with a plurality of bolt holes 417b on a horizontal plane 417p, and a separator 414 is attached using the bolt holes 417b and bolts 417B. That is, the separator 414 is fixed to the bracket 417.

  By the way, in this sorter 4, a total of four round holes 414h are provided at one end of the separator 414 (see FIG. 8A), and a total of twelve bolt holes 417b are provided in the plane 417p of the bracket 417. It has been. The round holes 414h and the bolt holes 417b are equally spaced from each other. Therefore, the mounting position of the separator 414 is moved to the front side by overlapping the round hole 414h of the separator 414 with the bolt hole 417b in front of the bracket 417 and tightening the bolt 417B (FIG. 9A). The distance D is shifted to the front side from the standard position S shown in FIG. On the contrary, the mounting position of the separator 414 is moved to the rear side by overlapping the round hole 414h of the separator 414 with the bolt hole 417b after the bracket 417 and tightening the bolt 417B (FIG. 9 ( The distance D is shifted rearward from the standard position S shown in A): see FIG. 9C).

  Thus, the separator 414 has a structure in which the mounting position can be adjusted in the front-rear direction. Thereby, the attachment position of the separator 414 can be changed according to the kind of crop. Therefore, the sorting accuracy of the grain G and the sorting speed of the grain can be improved.

  In addition, in this sorter 4, sieving line 414S makes the tip part of spike 414s jump out to the back rather than the end 431e of the first flow cereal plate 431 (regarding the end 431e of the first flow cereal plate 431) regardless of the attachment position. It protrudes to the rear side of the perpendicular L that passes through (see FIGS. 9A, 9B, and 9C). Thereby, among the cereal C sent from the net part 414M of the separator 414, the cereal C containing relatively small swarf etc. S falls to the chaff sheave 412 and the relatively larger swarf etc. S About the cereal C containing, it falls to the Strollac 413. Therefore, it becomes possible to improve the selection accuracy of the grain G.

  Next, a sorting device 4 according to another embodiment will be described.

  FIG. 10 shows a structure for attaching the separator 414. FIG. 11 shows each state when the attachment position of the separator 414 is changed.

  In the sorting device 4, the feed pan 411, the chaff sheave 412, and the stroller 413 are supported by the side frame 416. The separator 414 is also supported by the side frame 416.

  The side frame 416 is disposed in parallel to the front-rear direction of the combine 100. The side frame 416 is provided with a plurality of bolt holes 416b along the front-rear direction, and a bracket 417 is attached using the bolt holes 416b and the rivet bolts 416B (FIGS. 10B and 10). (See (C)). That is, the bracket 417 is fixed to the side frame 416.

  The bracket 417 is a structure generally called “L-shaped angle”. The bracket 417 is fixed in a state where one plane is in contact with the side frame 416, so that the other plane 417p becomes horizontal. The bracket 417 is provided with a plurality of bolt holes 417b on a horizontal plane 417p, and a separator 414 is attached using the bolt holes 417b and bolts 417B. That is, the separator 414 is fixed to the bracket 417.

  By the way, in the sorting apparatus 4, a total of four long holes 414h are provided at one end of the separator 414 (see FIG. 10A), and a total of four bolt holes 417b are provided on the flat surface 417p of the bracket 417. ing. The long hole 414h and the bolt hole 417b are equally spaced from each other. Therefore, the mounting position of the separator 414 is moved to the front side by tightening the bolt 417B by overlapping the rear end of the long hole 414h of the separator 414 with the bolt hole 417b of the bracket 417 (see FIG. 11A). The distance D is shifted forward from the standard position S shown: see FIG. On the contrary, when the front end of the long hole 414h of the separator 414 is overlapped with the bolt hole 417b of the bracket 417 and the bolt 417B is tightened, the mounting position of the separator 414 moves to the rear side (FIG. 11A). The distance D is shifted rearward from the standard position S shown in FIG. 11 (see FIG. 11C).

  Thus, the separator 413 has a structure in which the mounting position can be adjusted in the front-rear direction. Thereby, the attachment position of the separator 414 can be changed according to the kind of crop. Therefore, the sorting accuracy of the grain G and the sorting speed of the grain can be improved.

  In addition, in this sorter 4, sieving line 414S makes the tip part of spike 414s jump out to the back rather than the end 431e of the first flow cereal plate 431 (regarding the end 431e of the first flow cereal plate 431) regardless of the attachment position. Jumps out to the rear side of the perpendicular L that passes through (see FIGS. 11A, 11B, and 11C). Thereby, among the cereal C sent from the net part 414M of the separator 414, the cereal C containing relatively small swarf etc. S falls to the chaff sheave 412 and the relatively larger swarf etc. S About the cereal C containing, it falls to the Strollac 413. Therefore, it becomes possible to improve the selection accuracy of the grain G.

  Below, the feature point of the sorting apparatus 4 used for this combine 100 is demonstrated.

  In the sorting device 4, a second blower 45 can be attached between the first rod 43 and the second rod 44. Below, the air blower 42 is demonstrated as "the 1st air blower 42".

  FIG. 12 shows the sorting device 4 to which the second blower 45 is attached. In the figure, the direction in which the wind from the first blower 42 flows and the direction in which the wind from the second blower 45 flows are shown. FIG. 13 shows the mounting structure of the second blower 45.

  Even if this sorter 4 is a specification in which the presence or absence of second blower 45 is different, other components are common. This is because a vent hole 45h is provided in the case 442 for the specification to attach the second blower 45, and in the specification in which the second blower 45 is not attached, the vent hole 45h is closed by the plate 443. .

  As described above, the ventilation holes 45 h are provided in the case 442, and the ventilation holes 45 h can be closed with the plate 443. Thereby, even if it is the specification from which the presence or absence of the 2nd air blower 45 differs, another component is common. Therefore, cost can be reduced.
