  Next, the swing selection mechanism will be described in detail with reference to FIG. The swing sorting board 52 includes sorting side plates 52a and 52a arranged on both left and right sides and a pre-sorting plate 52b arranged on the front side. On the swing sorter 52, a feed pan 71 and a chaff sheave 72 are arranged in order from the front side, and a glen sieve 73 is arranged below the chaff sheave 72. Both of these are attached to the left and right sorting side plates 52a and 52a, respectively. Further, a Strollac 74 is attached to the downstream side (rear end side) of the chaff sheave 72. The attachment of the Strollac 74 will be described in detail later.

  The pre-sorting plate 52b of the swinging sorter 52 is provided in an obliquely downward inclined posture with the upper end side inclined forward. In front of the swing selection board 52, a swing drive shaft 75 and a crank rod 76 driven by power from the engine 20 are provided as a swing mechanism, and are attached to the rear end side of the crank rod 76. The support plate 76a is fixed to the front side of the pre-sorting plate 52b of the swing sorting plate 52. As the swing drive shaft 75 rotates, the swing sorter 52 is configured to reciprocate from the diagonally lower front to the diagonally upper rear through the crank rod 76 and the support plate 76a. A guide body (not shown) for guiding the reciprocating movement of the swing sorting plate 52 is provided at a portion near the rear end of the left and right sorting side plates 52 a of the swing sorting plate 52.

  The sorting air from the tang fan 53 is formed so as to move from the lower front side of the Glen sheave 73 toward the upper rear side of the Glen sheave 73.

The processed product) falls on the second conveyor 56 and the second basket 56a. The second sorted product taken out by the second conveyor 56 is returned to the upper surface side of the feed pan 71 via the second reducing cylinder 58 and re-sorted.

  In addition, due to the specific gravity sorting action of the chaff sheave 72 and the wind selection of the sorting wind from the tang fan 28, the grain on the upper layer side (heavy material) of the degranulated product moves to the lower layer side and leaks early from the chaff sheave 72. Will do. The specific gravity sorting action of the chaff sheave 72 is facilitated by the sorting wind from the tang fan 28, and the sorting processing capacity (sorting accuracy) is improved.

  Relatively light debris on the upper surface side of the chaff sheave 72 and stroller 74 is sucked into the suction port 61a on the front side of the dust exhaust fan 61 and is discharged out of the machine from the dust exhaust port 61b on the rear side of the dust exhaust fan 61. Will be. Further, relatively heavy sawdust that has moved from the downstream side (rear side) of the chaff sheave 72 to the upper surface side of the stroller 74 is discharged from the third port 60 on the rear end side of the swing sorter 52 to the outside. It will be. As shown in FIG. 3, the sheet material 64 is attached so as to hang down from the lower part of the dust exhaust fan 61 toward the upper side of the stroller 74, and the suction performance of relatively light sawdust to the suction port 61 a is achieved.

  Note that the sorting air from the Kara fan 53 is sucked into the dust exhaust suction port 61a of the dust exhaust fan 61 and discharged from the dust exhaust port 61b, or moved to the rear of the traveling machine body 1 from the third port 60. The sawdust, dust, etc. in the crushed material from the handling cylinder 51 are discharged from the rear part of the traveling machine body 1 toward the field.

  Next, attachment of the Strollac 74 will be described with reference to FIGS. A rack base material 80 for attaching a Strollac 74 is provided at the rear end portion of the chaff sheave 72 of the swing sorter 52. The rack base material 80 has a plate shape that is long to the left and right, and the left and right ends of the rack base material 80 are bent, and the left and right sorting side plates 52a and 52a of the swing sorter 52 are respectively bolted 80a and nut 80b. It is attached.

  In the Strollac 74, a plurality of Strollack pieces 77a which are long in the front-rear direction and whose upper end side is formed in a substantially waveform in a side view are arranged in the left-right direction. More specifically, the front end sides of the two strolac pieces 77a are connected by the substrate portion 78, thereby forming a U-shaped stroller body 77 in plan view. The Strollac body 77 is formed by bending one steel plate so as to be U-shaped in plan view, thereby forming two Strollac pieces 77a in parallel and connecting the front end sides of each Strollac piece 77a. The portion is a substrate portion 78. Further, the upper end side of the substrate portion 78 is bent in a tongue shape toward the rear (in a direction away from the rack base material 80), and a reinforcing piece 83 is formed.

  Reinforcing ribs 82 that are continuous with the substrate portion 78 and the two strolac pieces 77a and 77a are formed at a substantially central portion in the vertical direction of the strollac body 77. The reinforcing rib 82 is recessed so that the outside opens. That is, the reinforcing ribs 82 provided on the board portion 78 are formed so as to protrude away from the rack base material 80 side, and the reinforcing ribs 82 provided on both the strolac pieces 77a and 77a face the inside of the U shape. The protrusion is formed. The substrate section 78 and the left and right Strollac pieces 77a, 77a have a section modulus that is increased by recessing the reinforcing rib 82, and the strength is improved.

  Further, the substrate portion 78 is provided with a reinforcing rib 82, so that a concave portion 82 a that opens toward the rack base material 80 is formed at a substantially central portion in the vertical direction of the substrate portion 78. Mounting holes 81 are formed through the substrate portion 78 at two locations above and below the recess 82a (see FIG. 6). Bolts 85 are inserted into the mounting holes 81 from the rack base material 80 side, and the Strollac body 77 is fastened to the rack base material 80 by the bolts 85 and nuts 85a (see FIG. 7). Thus, since the front end side (feed start end side) of the plurality of Strollac bodies 77 is fastened to the rack base material 80, the rear end side (feed end side) of the Strollac body 77 is a free end. The material is cantilevered by 80. In the rack base material 80, a plurality of Strollac bodies 77 are arranged side by side in the left-right direction.

  As the swing sorter plate 52 swings, the Strollac body 77 reciprocates from the front diagonally downward to the rear diagonally upward and swings in the front-rear direction and the vertical direction. Since the material 80 is cantilevered, the feed end side of the Strollack piece 77a can swing in the left-right direction. In this embodiment, as shown in FIGS. 5 and 7, a weight 84 for resonating the rack base material 80 is provided on the front surface of the rack base material 80 as a vibrating body 90 that swings the Strollac piece 77 a in the left-right direction. It is stuck.

  The mass of the weight 84 is selected according to the natural frequency of the rack base material 80. If the rack base material 80 is caused to resonate with the swing of the swing sorting plate 52 by fixing the weight 84, the resonance of the rack base material 80 is transmitted to each Strollac piece 77a. As shown in FIG. 5, since the left and right ends of the rack base material 80 are fixed to the left and right sorting side plates 52a of the swing sorter 52, respectively, the left and right sides of the rack base material 80 are resonated when the rack base material 80 resonates. The central part of the direction bends back and forth. Accordingly, the rear end sides of the plurality of Strollac pieces 77a that are cantilevered by the rack base material 80 are largely swung in the left-right direction. As a result, the shaking action by the Strollac 74 is comprehensively enhanced, and the sorting performance can be improved.

  As shown in FIG. 5, the upper end portion of the rack base material 80 is bent rearward to form a flange portion 87. The upper portion of the substrate portion 78 of the Strollac body 77 is covered by the flange portion 87. As a result, it is possible to greatly reduce the inconvenience that clogs or the like are clogged between the base end portion 78 of the Strollac body 77 and the rack base material 80 (gap between the fastening portions).

  As described above, the Strollac 74 and the rack base material 80 vibrate not only in the front-rear direction and the vertical direction but also in the left-right direction due to the resonance of the rack base material 80. Therefore, these materials have excellent strength and toughness. It is desirable to select a material, and a material having high strength against repeated loads such as spring steel, high-tensile steel plate, resin, rubber, etc. is suitable. Further, the Strollac body 77 is bolted to the rack base material 80 at a plurality of locations to make it difficult for stress to be concentrated at the fixing location between the Strollac 74 and the rack base material 80.

  As a form for vibrating the Strollac 74 in the left-right direction, the first embodiment described above can be variously modified. 8 and 9 show a second embodiment. In the second embodiment, a weight 84 is attached to the rear end side of each Strollac piece 77a as the vibrating body 90. FIG. The weight 84 is disposed so as to be unbalanced by the plurality of Strollac pieces 77a. The weights 84 may be arranged at different positions for each Strollac piece 77a, or may be unbalanced by making the weights of the weights 84 different.

  If the weights 84 are arranged in an unbalanced manner on the Strollac 74, the mass of the plurality of Strollack pieces 77a becomes unbalanced, so that each Strollack piece 77a can be swung in the left-right direction at different periods or different displacements. As a result, the shaking action of the stroller 74 can be improved and the sorting performance can be enhanced. In addition, since the weight 84 is attached to the rear end side, which is the free end of the Strollac piece 77a, it is possible to effectively induce left-right oscillation in the Strollack piece 77a.

  FIG. 10 shows a third embodiment. In the third embodiment, similarly to the first embodiment, the weight 84 is attached so as to resonate the rack base material 80 as the vibrating body 90. In this embodiment, the rack base material 80 is formed in a flat plate shape, and the front and rear ends of the rack base material 80 are sandwiched by two brackets 86 and fastened by bolts 86a and nuts 86b. It is fixed with bolts 88a and nuts 88b. By adopting a structure in which the left and right ends of the flat rack base material 80 are sandwiched between the brackets 86 in this way, vibration in the left-right direction of the Strollac 74 becomes difficult to be transmitted to the other parts of the swing sorter 52, and noise is reduced. Occurrence etc. can also be suppressed.

  A through hole (not shown) of the rack base material 80 through which the bolt 86a is inserted may be formed in a long hole shape that is long in the left-right direction. With this configuration, the rack base material 80 itself can be displaced in the left-right direction, so that vibration of the stroller 74 in the left-right direction can be further promoted.

  Further, the fourth embodiment shown in FIG. 11 is an application of the third embodiment, and a rubber-like member 91 is interposed as an elastic body between the rack base material 80 and the bracket 86. The rubber-like member 91 amplifies the vibration in the front-rear direction of the rack base material 80, and accordingly, the vibration in the left-right direction of the stroller 74 is increased, so that the sorting performance of the stroller 74 is improved. Further, the rubber-like member 91 absorbs the vibration in the front-rear direction of the rack base material 80 and is difficult to be transmitted to the other part of the swing sorter 52, and the generation of noise and the like can also be suppressed. Instead of the rubber-like member 91, another elastic body such as a disc spring or a spring spring may be used.

  FIG. 12 shows a fifth embodiment. A concave portion 82a is formed on the rack base material 80 side by providing a reinforcing rib 82 on the substrate portion 78 of the Strollac body 77. In this embodiment, the vibrating body 90 can be moved inside the concave portion 82a. A simple weight 84 is arranged. More specifically, a filling material 93 is filled in the recess 82 a, and a cavity 92 is formed inside the filling material 93 for movably storing a weight 84.

  Further, the base plate portion 78 of the Strollack body 77 is fastened to the rack base material 80 with bolts 85 and nuts 85a. A disc spring 94 is disposed as an elastic body between the bolts 85 and the nuts 85a. As the rack base material 80 vibrates in the front-rear direction, the weight 84 moves in the cavity 92, and the movement of the weight 84 induces vibration in the left-right direction of the stroller 74. In addition, because the elastic force of the disc spring 94 promotes left-right vibration of the stroller 74, the vibration action of the stroller 74 can be greatly improved. Instead of the disc spring 94, another elastic body such as a spring spring or a rubber-like member may be used.

  Moreover, it cannot be overemphasized that the various embodiment mentioned above may be implemented in arbitrary combinations.

  As described above, the combine 100 of the present embodiment includes the harvesting device 3 that harvests the cereal, the threshing device 5 that threshs the harvested cereal, and the swing sorter 52 that sorts the threshing material from the threshing device 5. A stroller 74 disposed on the swing sorter 52. The feed end side of the Strollac 74 is provided with a vibrating body 90 that can swing in the left-right direction, and the feed end side of the Strollac 74 is shaken in the left-right direction by the swinging movement of the swing sorting board 52. It is configured to move. Accordingly, the Strollac 74 swings in the same direction as the swing movement of the swing sorting board 52 and also swings in the left-right direction, so that the swinging action of the Strollack 74 is enhanced. As a result, the sorting performance in the Strollac 74 is improved, so that even if there is a large amount of processed material transferred to the Strollack 74, it is possible to quickly filter and sort the soot and soot. This loss can be greatly reduced.

  Further, a Strollac 74 is disposed between the left and right sorting side plates 52a of the swing sorter 52 via a rack base material 80, and the feed start end side of the Strollack 74 is cantilevered by the rack base material 80, and the vibrating body 90 A weight 84 for resonating the rack member 80 is attached, and the feed end side of the stroller 74 is swung in the left-right direction by the resonance of the rack member 80. By adjusting the mass of the weight 84, the rack base material 80 can be easily resonated, so that the sorting performance at the Strollac 74 can be improved by a simple specification change.

  Further, the Strollac 94 includes a plurality of Strollack pieces 77a arranged in the left-right direction, and a weight 84 is attached to the feed end side of the Strollack piece 77a as the vibrating body 90, and the weight 84 is unbalanced with the plurality of Strollack pieces 77a. Is arranged. Therefore, the feed end side of each Strollac piece 77a can be vibrated unbalanced with a different vibration period or different displacement amount in the left-right direction by the weight. That is, the sorting performance in the Strollac 74 can be improved by a simple specification change in which the weight 84 is attached to the Strollack piece 77a. Further, since the weight 84 is arranged on the feed end side, which is the free end side of the Strollack piece 77a, it is possible to efficiently generate the left-right vibration in the Strollack piece 77a.

  In addition, since the swinging motion of the swing sorter 52 is transmitted to the Strollac 74 via the elastic body 91 (94), it is possible to change the specification simply by interposing the elastic body 91 (94). The swing motion of the swing sorter can be amplified by the elastic body 91 (94) and transmitted to the stroller 74. Further, by selecting the elastic body 91 (94), it is possible to easily adjust the strength of the vibration operation of the Strollac 74 and to select the swing range in the left-right direction.
