Has been.

  That is, the sorting units 48A, 48B, 48C, and 48D are detachably attached to the swinging sorter 29, but different types of sorting units 48B and 48C can be alternatively attached to the same fixed plate 49. It is. The configuration of the sorting units 48A, 48B, 48C, 48D will be described later.

First, configurations other than the sorting units 48A, 48B, 48C, and 48D will be described.
The Glen pan 41 is formed in a wave shape that is continuous with a mountain and a valley whose back side is sharp in a side view. While the sorting wind is generated and the swinging sorter 29 is moving back and forth, the glen pan 41 receives the processed material falling from the handling chamber 19 via the receiving net 23 and performs this processing. An object is caused to flow backward by a back and forth swinging action. In this backward flow process, the processed material is stratified vertically by the difference in specific gravity, and the processed material on the lower layer side having a higher specific gravity falls downward, while the processed material on the upper layer side having a lower specific gravity is applied to the chaff sheave 42. Take over.

  The chaff sheave 42 is configured by arranging a plurality of plate-like fins 42a extending in the left-right direction in front and rear. The fin 42a is formed of a movable fin 42a that can swing back and forth, and the fixed plate 49 is disposed behind the movable fin located at the rearmost end.

  The fixed plate 49 is fixed to the side frames 36 and 36 in a state where the fixed plate 49 is inclined obliquely forward and downward in a side view, whereby the fixed plate 49 is one of the frame bodies of the swinging sorter 29 together with the side frames 36. Part.

  The plurality of movable fins 42a arranged in the front-rear direction are attached and fixed to the support shaft 42b in the left-right direction that is pivoted between the side frames 36, 36 so as to be rotatable about the axis. Is mounted and supported between the side frames 36 and 36 so as to be swingable back and forth, integrally with the support shaft 42b on its upper end side. Then, the opening between the front and rear adjacent fins 42a, 42a is changed by swinging the movable fin 42a back and forth, thereby adjusting the opening of the chaff sheave 42.

  The plurality of movable fins 42a are grouped into a plurality of fin groups 53A, 53B, 53C, and 53D, and each fin group 53A, 53B, 53C, and 53D includes a plurality of adjacent (four or five in the illustrated example). It is comprised by the fin 42a. Specifically, the four fin groups 53A include a group of the fins 42a on the foremost end side, a group of the fins 42a on the rearmost end side, and two groups of front and rear fins 42a sandwiched between the groups of the two fins 42a. , 53B, 53C, and 53D.

  Each fin group 53A, 53B, 53C, 53D has a connecting plate 42c in the front-rear direction that connects all the fins 42a constituting itself, and an open / close arm 54 that performs a swinging operation of the fins 42a constituting the fin group 53A, 53B, 53C, 53D. Is provided.

  The connecting plate 42c connects the lower end portions of the plurality of fins 42a so as to be pivotable back and forth, and maintains the same swinging posture of the connected fins 42a. The connecting plate 42c includes the fin group 53A, Since it is provided for each of 53B, 53C, and 53D, the forward / backward swing posture of the fin 42a is controlled in units of the fin groups 53A, 53B, 53C, and 53D.

  The upper and lower ends of the open / close arm 54 are fixed to the support shaft 42b of one fin 42a constituting the fin group 53A, 53B, 53C, 53D. Therefore, the open / close arm 54 is pivoted back and forth integrally with the support shaft 42b (fin 42a) in a state of extending downward from the support shaft 42b, and the fin groups 53A and 53B are operated by the back-and-forth swing. , 53C and 53D are swung back and forth together.

  A contact roller 56 is provided at the lower end portion of the open / close arm 54 so as to be freely rotatable, and a single lower side of the contact roller 56 is in contact with the contact roller 56 of the plurality of open / close arms 54. One cam plate 57 extending in the front-rear direction, a gear mechanism 58 that moves the cam plate 57 back and forth, a motor (actuator) 59 that drives the cam plate 57 to move back and forth via the gear mechanism 58, and the front and rear of the cam plate 57 A potentiometer 61 is provided as position detecting means for detecting the position.

  The contact position of each contact roller 56 with the cam plate 57 is changed depending on the front and rear position of the cam plate 57, and the change of the contact position causes the open / close arm 54 to swing back and forth, and the fin groups 53A and 53B. , 53C, 53D change the posture of the fins, and the opening degree of the chaff sheave 42 is optimally controlled.

  On the upper end surface of the cam plate 57, a plurality of cam portions 57a, 57b, 57c, and 57d that are in contact with the contact rollers 56 of a plurality of opening and closing arms 54 that are arranged in the front and rear are arranged in the front and rear. Specifically, a cam portion (first cam portion) 57a that comes into contact with the contact roller 56 of the opening / closing arm 54 for the first fin group, which is the frontmost fin group, and the second fin group from the front. The cam portion (second cam portion) 57b that contacts the contact roller 56 of the second fin group opening / closing arm 54 and the third fin group opening / closing arm 54 that is the third fin group from the front. The cam portion (fourth cam portion) 57c that contacts the roller 56 and the contact roller 56 of the opening / closing arm 54 for the fourth fin group that is the frontmost fin group (the third cam portion) 57c. ) 57d are sequentially arranged from the front side in this order.

  That is, the opening degree of each fin group 53A, 53B, 53C, 53D is adjusted by the shape of each cam part 57a, 57b, 57c, 57d, and each cam part 57a, 57b, 57c, 57d is horizontal. The lower step surface and the upper step surface, and an inclined surface inclined upward toward the rear so as to connect the lower step surface and the upper step surface.

  When the contact roller 56 is in contact with the lower step surface of the cam portion so as to be able to rotate back and forth, the movable fin 42a is swung to the lowest position, and the opening between the movable fins 42a is maximized. When the contact roller 56 is in contact with the upper stage surface so as to be freely rotatable back and forth, the movable fin 42a is swung to the uppermost position, the opening between the movable fins 42a is minimized, and the cam surface is inclined. When the contact roller 56 is in contact with the front and rear, the movable fin 42a swings back and forth due to the back and forth movement of the cam plate 57, and the opening between the movable fins 42a increases and decreases.

  For this reason, in each cam part 57a, 57b, 57c, 57d, the position of the upper step surface, the lower step surface, and the inclined surface and the inclination degree of the inclined surface are set in advance, so that the chaff sheave is set to each front and rear position of the cam plate 57. It is possible to obtain an optimum opening of 42. Incidentally, each open / close arm 54 is always urged toward the corresponding cam portion by providing a torsion coil spring 55 as an elastic member, and the contact state between the two is always kept good.

  As described above, the opening degree of the chaff sheave 42 can be easily changed by the back and forth movement of the plurality of movable fins 42 a, and the amount of air that the sorting wind blows up to the upper side of the swinging sorter 29 by changing the opening degree of the chaff sheave 42. The amount of leakage of the processed material is adjusted. Specifically, when the connecting plate 42c is operated to swing forward, the opening of the chaff sheave 42 is narrowed and the processed material is difficult to drop downward. By operating the connecting plate 42c to swing backward, the chaff sheave 42 is moved. The opening can be widened and the processed material can be easily dropped.

  While the sorting wind is generated and the swing sorting body 29 is moving back and forth, the processed material on the chaff sheave 42 taken over from the grain pan 41 is dropped by the swing action and the wind sorting action of the sorting wind. And those to be handed over to a stroller formed by a sorting unit 48C described in detail later.

Next, the configuration of the sorting units 48A, 48B, 48C, 48D will be described.
As shown in FIGS. 3 and 4, the first sorting unit 48A includes two fixed fins 62 and 71, a plurality of movable fins 63 arranged in parallel in the front and rear directions, and a plurality of Strolacks arranged in parallel on the left and right. 64 is unitized.

  Specifically, a pair of left and right connecting bodies 66 and 66 that are respectively fixed to the rear mounting holes 51 of the left and right side frames 36 and 36 and extend in the front-rear direction, and the plurality of movable fins 63 are connected to the left and right connecting bodies 66. , 66 are provided with the same number of support shafts 67 as the movable fins 63 that are swingably supported, and the support shafts 67 are configured substantially the same as the support shaft 42b described above. In addition, one fixed fin 62 is bolted to the front side of the movable fin 63 in an inclined state.

  The plurality of movable fins 63 constitute a fin group 53E, and the fin group 53E is configured in substantially the same configuration as the above-described connection plate 42c, together with a connecting plate 68 in the front-rear direction that connects the movable fins 63 to each other. An opening / closing arm 54 with a contact roller 56 that is configured to be substantially the same as the above-described opening / closing arm 54 and that swings the movable fin 63 back and forth is attached.

  The contact roller 56 of the first sorting unit is in contact with a plate-like extended cam plate (interlocking mechanism) 69 extending in the front-rear direction on the side surface of the cam plate 57 of the side frame 36 from above. The extension cam plate 69 has a plurality of (three in the illustrated example) connection holes 70 in the front-rear direction on the front end side, and is detachably connected to the rear end side of the cam plate 57 with bolts. Therefore, it is configured to move back and forth integrally with the cam plate 57.

  Further, a cam portion 69 a having the same shape as the cam plate 57 is formed at the rear upper end of the extension cam plate 69. Note that the cam plate 57 and the extension cam plate 69 may be connected by pin fixing. In this case, by providing a buffer material in the connection hole 70 used for connection, wear of the connection portion, noise, and the like are reduced. Can be reduced.

  As a result, the contact position between the contact roller 56 of the open / close arm 54 and the cam portion 69a is changed depending on the longitudinal position of the extension cam plate 69, and the change of the contact position causes the open / close arm 54 to swing back and forth. The opening degree of the movable fins 63 constituting the fin group 53E is controlled. In addition, in the extension cam plate 69, the contact point between the contact roller 56 and the cam portion 69a is changed by selecting which connection hole 70 is connected to the cam plate 57, and the fin group 53E rotates. You can adjust the timing.

  In addition, the first sorting unit 48A is configured such that a mounting plate 72 that is inclined obliquely is fixed to the rear side of the fin group 53E of the coupling body 66, and a stroller 64 is mounted on the mounting plate 72. . Specifically, the front end side of each of the plurality of rack plates 64a extending in the front-rear direction and aligned in the left-right direction is fixed to the fixed fin 71 that is long in the left-right direction by welding or the like, thereby forming the strola rack 64. The Strollac 64 is provided with a mounting pin (P button) 50 projecting from the mounting plate 72 of the first sorting unit 48 </ b> A toward the rear lower side and having a screw formed on the outer periphery. It is attached by being inserted through the drilled insertion hole and fastened and fixed with a nut.

  The first sorting unit 48A configured as described above can be detachably attached to the side frame 36 side by bolting the connecting body 66 to the rear side attachment hole 51 on the side frame 36 side.

  As shown in FIG. 3, the second sorting unit 48B includes a front fin 73a extending to the left and right that is fixed to the fixing plate 49 provided on the side frame 36, and a cylindrical spacer 74 on the rear side of the front fin 73a. And rear fins 73b fixed with bolts. The second sorting unit 48B having the above configuration is detachably attached to the side frame 36 side by attaching the front fin 73a to the fixing plate 49 using the attachment pin 50 described above.

  As described above, according to the swing sorter shown in FIGS. 3 and 4, the chaff sheave 42 in which the processed material is less likely to fall compared to the Strollac 64 can be extended further to the rear side than the first guide 46. It is possible to reduce the amount of the processed material that falls on the second spiral 34 and is reduced and conveyed. In other words, the first item is selected as much as possible in the first selection operation, and the amount of processed material reduced and transported by the second spiral 34 is reduced, so that even if some grain remains, it is discharged outside the machine. Therefore, when sorting processed products having relatively large grains such as soybeans, the problem of the grains becoming easily soiled can be avoided if they are reduced and conveyed and passed through the threshing unit 17 and the sorting unit 18 again. Further, even a processed product that has a large number of second products and whose reduction path is easily clogged can be smoothly selected without clogging the second helix 34 or the like.

  The mounting plate 72 may have a configuration in which an extension chaff sheave (not shown) made up of a plurality of fins is attached in place of the Strollac 64. According to this, the chaff sheave 42 is extended to the rear end side of the swing sorter 29.

  As shown in FIG. 5, the third sorting unit 48C is a unit by fixing the front end sides of a plurality of rack plates 76 extending in the front-rear direction and arranged in the left-right direction to fixing fins 77 that are long in the left-right direction by welding or the like. It is a standardized Strollac. The third sorting unit 48C configured as described above is detachably attached to the side frame 36 side by attaching the fixing fins 77 to the fixing plate 49 using the mounting pins 50 described above.

  As shown in FIG. 5, the fourth sorting unit 48D has a configuration in which an auxiliary chaff portion 78 and an auxiliary rack portion 79 are integrally unitized. Specifically, the auxiliary chaff portion 78 includes a plurality of auxiliary fins 78a that extend in the left-right direction and are arranged in the front-rear direction, and a pair of long long in the front-rear direction that connects the plurality of auxiliary fins 78a by fixing the left and right ends of the auxiliary fins 78a. The connecting body 78b. The auxiliary rack portion 79 is formed by fixing a front end of a plurality of auxiliary rack plates 79a which are formed longer than the rack plate 76 and are arranged on the left and right sides to a fixed fin 81 which is an auxiliary fin 78a disposed at the rear end. Yes.

  The fourth sorting unit having the above configuration can be detachably attached to the side frame 36 by fixing the connecting plate 78b to the lower attachment hole 52 on the side frame 36 side.

  As described above, according to the swing sorter shown in FIG. 5, the processed material that has dropped from the chaff sheave 42 can be collected most by the spiral 33, and the processed material that has not dropped by the chaff sheave 42 can be compared with the fins 42a. Accordingly, the second spiral 34 is actively treated with a bellows etc. via the rack plate 76 of the third sorting unit 48C, the auxiliary rack plate 79 of the fourth sorting unit 48D, etc. Can be recovered and transported in a reduced amount, so it is suitable mainly for sorting rice and wheat.

  Next, based on FIG. 6, a different point from the example mentioned above about the other example of a 1st selection unit is demonstrated.

  FIG. 6 is a side view of the main part of the swing sorting body showing the configuration of another example of the first sorting unit. The first sorting unit 48E includes a plurality of extension fins 81a that extend in the left-right direction and are arranged in the front-rear direction, and a pair of connection bodies 81b that are long in the front-rear direction, and the first selection unit 48E includes an extension fin 81a disposed between the pair of connection bodies 81b. Both ends are fixed to the connecting body 81b side by welding or the like to form a unit.

  That is, the first sorting unit 48E may be configured such that the opening degree of the extension fin 81a cannot be adjusted. According to this configuration, the strength of the first sorting unit can be improved, and the number of parts can be reduced to reduce the cost.
