  The threshing sorting apparatus according to claim 1 is arranged so that the movable fin at the lower end is located on the lower side from the tip of the first flow plate, and thus the chopped rice cake that has fallen from the gap between the movable fin and the fixed fin The second thing such as sawdust can be guided to the second mouth without being guided to the first mouth by the first flow plate, and the second thing can be prevented from being mixed into the first thing. . Therefore, the threshing sorting apparatus according to claim 1 can increase the sorting rate of the processed products.

  The threshing sorting apparatus according to claim 2 has a protruding portion protruding toward the fixed fin side on the upper lower side of the movable fin at the lower end, so that the sorting wind of the blower fan passing between the fins The amount of passing air is reduced, the scattering of the second object placed on the movable fin and the fixed fin can be reduced, and the sorting rate of the processed object can be increased.

  In the threshing / sorting device according to the third aspect, the fixed fin is provided with a protruding portion that protrudes toward the adjacent fixed fin, so that the flow rate of the selection air of the blower fan passing between the fixed fins is reduced. The scattering of the second object placed on the fixed fin can be reduced and the sorting rate of the processed object can be increased.

  Hereinafter, a threshing sorting apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the description, the upper side or the upper side refers to the upstream side of the swing sorter 10 in the grain transfer direction, that is, the left side in FIG. Further, the lower flow or the lower side refers to the downstream side of the swing sorting body 10 in the grain transfer direction, that is, the right side in FIG.

  1 and 2, the threshing sorter 1 mainly receives a handling chamber 2 in which a handling cylinder 6 is housed, and a processed product (grain containing a mixture) dropped from the handling chamber 2 to swing the processed product. The swinging sorter 10 that sorts while moving, the tang fan 11 as a blower fan that blows the sorting air toward the swinging sorter 10, and the processed material leaked from the swinging sorter 10 are the second mouth and 1 And a first flow plate 37 that separates into a number gate and guides the flow down. The swing sorter 10 includes upper and lower chaff sheaves 18 and 19 as a two-stage upper and lower leakage sorter unitized between the left and right side plates 10b. The chaff sheave may be one stage. Moreover, you may provide 3 steps | paragraphs or more of the upper and lower sides.

  The threshing sorter 1 further includes a threshing feed chain 3 that transports the stalks along the handling chamber 2, a waste transporting device 5 that transports the threshed stalks to the post-processing unit 4, and the handling of the handling chamber 2. A first receiving net 7 in which the processed product threshed in the cylinder 6 leaks, and a processing cylinder 8 that performs a single grain processing on the processed product that has reached the end of the handling chamber 2 without leaking from the first receiving net 7; The second receiving net 9 for letting the processed material that has been made into a single particle through the processing cylinder 8, the first spiral 12 provided in the first port 61 for collecting the first item, and the second port for collecting the second item No. 2 spiral 13 provided in 62, No. 2 selection fan 14 for blowing the No. 2 selection wind on the lower side of No. 2 spiral 13, a dust discharge chamber 15 provided above the terminal portion of the swing sorter 10, The dust exhaust chamber 15 is provided with a dust exhaust fan 16 that is rotatably mounted.

  The oscillating sorter 10 has a oscillating flow plate 17 that sequentially conveys the processed material leaked from the first receiving net 7 to the lower side, and a layered sort (specific gravity) of the processed material at the lower end of the oscillating flow plate 17. The upper and lower chaff sheaves 18 and 19 to be sorted), the Glen sheave 20 that sifts and sorts the processed material leaked from the upper and lower chaff sheaves 18 and 19 with a net member, and the straw rack 21 disposed on the lower side of the lower chaff sheave 19. And the like. The swing sorting body 10 is supported in the sorting chamber S so as to be swingable, and continuously swings back and forth at a predetermined cycle by a drive mechanism (a crank mechanism, a cam mechanism, etc.) not shown. Yes.

  On the lower side of the swing sorting body 10, a pair of left and right handles 10a made of a U-shaped plate are provided by welding. The handle 10a is provided to make it easy to hold the swing sorting body 10 when the swing sorting body 10 is taken in and out (detached).

  The upper and lower chaff sheaves 18 and 19 are each unitized and arranged vertically with a predetermined interval. The grains transferred to the lower side from the oscillating flow plate 17 are subjected to the first layered sorting at the upper chaff sheave 18, then dropped onto the lower chaff sheave 19, and subjected to the second layered sorting on the lower chaff sheave 19. After that, it falls on the Glen sieve 20. Thus, since the threshing sorter 1 performs the two-stage layered sort by the upper and lower chaff sheaves 18, 19, the sorting accuracy and the sorting efficiency can be improved. In the present embodiment, the grain leaked from the lower chaff sheave 19 is further screened by the grain sieve 20, but the grain sieve 20 is not necessarily required.

  The Chinese fan 11 is housed in a fan case 22 and blows a selection wind toward the swinging sorter 10 from three blower openings 22a, 22b, 22c formed in the lower part thereof. The three air vents 22a, 22b, and 22c are arranged in the vertical direction, and the upper air vent 22a communicates with the upper side of the sorting air passage formed between the upper chaff sheave 18 and the lower chaff sheave 19. The middle air vent 22b is in communication with the upper side of the sorting air passage formed between the lower chaff sheave 19 and the glen sieve 20. The lower air blowing port (main sorting air passage air outlet) 22 c communicates with the upper side of the sorting air passage formed between the Glen sheave 20 and the first spiral 12.

  In this manner, when the three air outlets 22a, 22b, and 22c are arranged, the wind flows between the upper chaff sheave 18 and the lower chaff sheave 19, between the lower chaff sheave 19 and the Glen sheave 20, and between the Glen sheave 20 and the first spiral 12, respectively. Since the sorting is performed, the threshing sorting apparatus 1 can improve the sorting accuracy and sorting efficiency of the processed material.

  As shown in FIGS. 3 and 4, the upper and lower chaff sheaves 18, 19 include a plurality of movable fins 41, 51 and fixed fins 42, 52, 53 that are arranged in parallel at a predetermined interval in the upper and lower chute directions. . Each of the fins 41, 42, 51, 52, 53 is inclined to the lower side, and the grains are transferred from the gaps between the fins while the processed material is transferred to the lower side as the swinging sorter 10 swings. It is designed to leak.

  Since the upper side of the sorting air passage formed between the upper and lower two-stage chaff sheaves 18 and 19 is connected to the air outlet 22a of the Kara fan 11 (FIG. 1), the sorting that flows between the upper and lower two-stage chaff sheaves 18 and 19 is performed. Wind (a strong wind that has not passed through the lower chaff sheave 19) can easily pass through the upper chaff sheave 18. As a result, a strong wind blows from the upper chaff sheave 18 (so-called air curtain), which may not disturb the transfer of the processed material, but also a strong wind blowing from the upper chaff sheave 18 hits the processed material in the processing chamber 2. There is also the possibility of reducing the threshing accuracy.

  Therefore, in the threshing / sorting device 1 of the present embodiment, a bent portion 41b is formed at the upper end portion of the movable fin 41 constituting the upper chaff sheave 18 so as to suppress the blowing of the sorting wind. Specifically, the upper end portion of the movable fin 41 is bent to the lower side. In this way, even if the upper side of the sorting air passage formed between the upper and lower two-stage chaff sheaves 18 and 19 communicates with the air blowing port 22a of the Kara fan 11, the blowing of the sorting air in the upper chaff sheave 18 can be suppressed. it can. As a result, the transfer of the processed material on the upper chaff sheave 18 is not hindered, or the processed material in the handling chamber 2 is not adversely affected, and good wind sorting is performed between the upper and lower chaff sheaves 18 and 19. Can do.

  The lower end 18a of the upper chaff sheave 18 is a line L connecting the upper end 22ca of the lower air blowing port (main sorting air outlet) 22c, which is the outlet of the main sorting wind, and the upper part 15a of the dust chamber 15. It is located on the better side. In this way, the upper chaff sheave 18 does not affect the flow of the main sorting air, so that the main sorting air can be well blown and the sorting accuracy can be improved.

  The movable fins 41 and 51 constituting the upper and lower chaff sheaves 18 and 19 can be adjusted in fin angle. In accordance with the fin angle adjustment, gap adjustment between the fins (hereinafter referred to as fin opening adjustment) is performed. For example, the type of processed material (for example, rice, wetting material, wheat, etc.), the amount of processed material on the oscillating flow plate 17 and the upper and lower chaff sheaves 18 and 19, the air volume and wind speed in the sorting air passage, the vehicle speed of the combine, etc. The fin opening is adjusted accordingly. In the threshing sorting apparatus 1 of the present embodiment, the fin opening adjustment mechanisms 23 and 24 of the upper and lower chaff sheaves 18 and 19 are individually provided in order to make it possible to adjust the fin opening of the upper and lower chaff sheaves 18 and 19. . In this way, the opening degree of the upper chaff sheave 18 and the lower chaff sheave 19 can be individually adjusted, and the opening degree of various patterns can be adjusted. As a result, the threshing / sorting device 1 of the present embodiment makes it possible to adjust a wide range of opening, and improve the selection accuracy and efficiency, compared to the case where the upper and lower chaff sheaves 18 and 19 are linked to adjust the opening. be able to.

  Next, the fin opening adjustment mechanisms 23 and 24 will be described with reference to FIGS. The movable fins 41 and 51 constituting the upper and lower chaff sheaves 18 and 19 can be rotated about the rotation shafts 25 and 35 as rotation centers. The rotation shaft 35 is provided on the left and right side plates 54 of the unitized lower chaff sheave 19 (FIG. 8), which will be described later. The rotation shaft 25 is provided on left and right side plates (not shown) of the upper chaff sheave 18 that is unitized in the same manner as the lower chaff sheave 19.

  The movable fins 41, 51 are linked by a linkage rod 26, 36 with a predetermined number as a set, and rotate in conjunction with the rotation of the same set of movable fins 41, 51. The upper chaff sheave 18 according to the present embodiment includes three movable fins 41 that are linked and operated as one set, and one fixed fin 42. The lower chaff sheave 19 includes 19 tiltable movable fins 51 that are linked and operated as four groups (units of 4 to 6 sheets), one fixed fin 53 on the upper side, and two lower fins. It is composed of a fixed fin 52. The number of fins is not limited to the number in the present embodiment.

  In FIG. 4, the fin opening adjusting mechanism 24 of the lower chaff sheave 19 is slidable in the upper and lower direction along the arm 27 fixed to each pair of rotating shafts 35 and the side plate 10 b of the swing sorter 10. A drive plate 28, a motor 29 for forcibly sliding the drive plate 28, and a fin opening sensor 30 for detecting the position of the drive plate 28 are provided.

  The arm 27 is provided with a rotatable roller 27a at the tip, and is pulled upward by a spring (not shown) so that the roller 27a contacts the cam piece 28a of the drive plate 28. The drive plate 28 is supported so as to be slidable in the left-right direction in FIG. 4 by fitting a long hole 28b to a pair of guide pins 10c projecting side by side in the upper-lower direction of the side plate 10b. The drive plate 28 has a rack 28c formed on the upper side. The motor 29 has a speed reduction mechanism, and the drive plate 28 is forcibly slid by forward / reverse driving of a pinion gear 29a meshing with the rack 28c. The fin opening sensor 30 is composed of, for example, a potentiometer, and a detection arm 30a fixed to the sensor shaft is press-engaged with a part of the drive plate 28 to detect the position of the drive plate 28.

  As described above, the fin opening adjustment mechanism 24 of the lower chaff sheave 19 is an electric type that changes the opening of the movable fin 51 in accordance with the drive of the motor 29. When the motor 29 is driven, the drive plate 28 slides and the arm 27 rotates. The arm 27 is provided on the rotation shaft 35 of the movable fin 51. For this reason, as the arm 27 rotates, the movable fin 51 also rotates. As a result, the opening degree of the movable fin 51 is changed. When the opening degree of the movable fin 51 is changed, the fin opening degree sensor 30 detects a change in the opening degree of the movable fin based on the position detection of the drive plate 28.

  The threshing sorting apparatus 1 of this embodiment includes a control unit 31 configured with a microcomputer or the like so that fin opening adjustment of the lower chaff sheave 19 can be performed by automatic control. The control unit 31 is connected to a motor 29, a fin opening sensor 30, an air volume sensor 32, and the like, and performs automatic fin opening adjustment of the lower chaff sheave 19. The air volume sensor 32 detects the amount of the processed material in the swing sorting body 10 based on the air volume of the main sorting air path. For example, the control unit 31 increases the fin opening of the lower chaff sheave 19 when the amount of processed material is large and the air volume sensor value is large, and when the amount of processed material is small and the air volume sensor value is small, The fin opening degree of the lower chaff sheave 19 is reduced. The air volume sensor 32 is provided in a detection air path that communicates the main sorting air path with the outside air, and detects the air volume of the main sorting air path based on the wind speed of the outside air that flows in according to the air volume of the main sorting air path. Do.

  On the other hand, the fin opening adjustment mechanism 23 of the upper chaff sheave 18 includes an arm 33 fixed to the rotating shaft 25 of the movable fin 41 and an opening adjustment bolt 34 for fixing the arm 33 at an arbitrary angle. ing. The arm 33 is formed with an arc-shaped elongated hole 33a centering on the rotation shaft 25, and an opening adjusting bolt 34 is penetrated therethrough. When the opening adjustment bolt 34 is loosened, the opening of the movable fin 41 can be adjusted manually. Further, when the opening adjustment bolt 34 is tightened, the rotation of the movable fin 41 is restricted. In other words, the opening degree of the movable fin 41 of the upper chaff sheave 18 is adjusted when changing the type of processed material (rice, wetting material, wheat, etc.), and cannot be adjusted darkly at other times.

  Therefore, the fin opening adjustment mechanism 23 of the upper chaff sheave 18 has a structure in which the opening of the movable fin 41 can be adjusted manually without using the opening adjusting actuator, thereby avoiding an increase in cost. Further, the opening degree of the movable fin 41 of the upper chaff sheave 18 and the opening degree of the movable fin 51 of the lower chaff sheave 19 can be individually adjusted.

  By the way, the 2nd thing such as shards and sawdust that have fallen from between the movable fin 51 and the fixed fin 52 of the lower chaff sheave 19 does not fall into the 2nd spiral 13 of the 2nd port 62 (FIG. 1). There is a risk of being guided to the first spiral 12 of the first port 61 by the first flow plate 37.

  That is, the opening degree of the fixed fin 52 is set to an opening degree corresponding to the maximum opening degree of the opening adjustment range of the movable fin 51. For this reason, in the state which opened the opening degree of movable fins 51 shown to Fig.7 (a), the clearance gap between movable fins 51, the clearance gap between fixed fins 52, and the clearance gap between movable fin 51 and fixed fin 52 Are almost the same. On the other hand, in the state shown in FIG. 7B in which the processed objects are few and the opening degree of the movable fins 51 is closed, the movable fins 51 are inclined and the gaps between the movable fins 51 are narrowed. And the gap between the fixed fins 52 widen. As a result, the second object such as sawdust falling from between the movable fin 51 and the fixed fin 52 increases, and the second object guided to the first spiral 12 of the first port 61 by the first flow plate 37. Become more.

  Therefore, the opening of the fixed fin 52 can also be adjusted so that the gap between the fixed fin 52 and the movable fin 51 at the lower end does not widen. However, the fixed fin 52 has the structure of the lower chaff sheave 19, The opening cannot be adjusted.

  That is, as shown in FIG. 8, the lower chaff sheave 19 is unitized by providing a fixed fin 53, a movable fin 51, a fixed fin 52, and a strok rack 21 in order from the upper side on a pair of left and right side plates 54. Yes. The unitized lower chaff sheave 19 is easily assembled between the left and right side plates 10b by attaching the left and right side plates 54 to the left and right side plates 10b of the swing sorter 10.

  In this case, the fixed fins 53 and 52 serve as members that connect the pair of left and right side plates 10b of the swing sorter 10. Therefore, the fixing fins 53 and 52 are fixed to the left and right side plates 54 of the lower chaff sheave 19 by bolts and nuts 55, and are consequently fixed to the left and right side plates 10b, so that the rocking sorter 10 can withstand rocking. It has a structure. In FIG. 8, reference numeral 56 indicates bolt holes for attaching the left and right side plates 54 to the left and right side plates 10 b of the swing sorter 10. For this reason, the fixed fin 52 is fixed without adjusting the opening.

  Therefore, the threshing sorting apparatus 1 of the present embodiment is arranged such that the movable fin 51 at the lower end (right end in FIG. 7) is positioned on the lower side from the tip 37 a of the first flow plate 37, A second object such as chopped chips and sawdust dropped from a gap with the fixed fin 52 is dropped to the lower side of the first flow plate 37. With this configuration, there is almost no second object received by the first flow plate 37 and guided to the first port 61. In addition, not only the movable fin at the lower end, but also a plurality of movable fins from the lower end to the upper side may be arranged so as to be positioned on the lower side from the tip 37a of the first flow plate 37.

  Thus, the threshing / sorting apparatus 1 can prevent the second thing 62 from being mixed into the first thing, and can increase the sorting rate of the processed material.

  Further, in the state where the movable fins 51 are closed (FIG. 7B), the gap between the movable fin 51 and the fixed fin 52 is widened, so that the amount of the selection air passing through the Chinese fan 11 passing through the gap is large. Therefore, the second object placed on the movable fin 51 and the fixed fin 52 may fly up and be scattered (the third scattering occurs) due to the sorting wind. Furthermore, by disposing the movable fin 51 at the lower end (right end in FIG. 7) so as to be located on the lower side from the tip 37a of the first flow plate 37, scattering of the first grain is more likely to occur. Become.

  Therefore, the threshing sorting apparatus 1 of the present embodiment has a bent portion 51a as a protruding portion protruding toward the fixed fin 52 side on the upper lower side of the movable fin 51 at the lower end (the right end in FIGS. 7 to 9). Projected.

  With such a configuration, the gap between the movable fin 51 at the lower end and the fixed fin 52 becomes narrower than in the case where there is no bending portion 51a, and the amount of the selection air passing through the Kara fan 11 is reduced. The second object placed on the fins 51 and the fixed fins 52 is less likely to be scattered by the sorting wind. Therefore, this threshing sorter 1 can raise the sort rate of a processed material.

  Further, in order to reduce the possibility that the second object placed on the upper portion of the fixed fin 52 will fly up and scatter due to the sorting wind of the Kara fan 11 is configured as follows.

  That is, the movable fin 51 and the fixed fin 52 are arranged at equal intervals (L1). The plurality of fixed fins 52 are provided with folds 52a and 52b that protrude toward the adjacent fixed fins at the upper and lower portions. Thus, the gap (L2) between the fixed fins 52 is narrower than the arrangement interval (L1) of the fixed fins 52. Further, a bent portion 52 b is projected from the fixed fin 52 facing the movable fin 51 toward the movable fin 51. Accordingly, the gap (L3) between the movable fin 51 and the fixed fin 52 is also narrower than the arrangement interval (L1) between the movable fin 51 and the fixed fin 52.

  Therefore, the flow rate of the selection air of the tang fan 11 passing between the fixed fins 52 and between the movable fins 51 and the fixed fins 52 is reduced as compared with the case where there are no folding parts 52a, 52b, 51a. For this reason, the second thing placed on the fixed fins 52 is less likely to be scattered by the sorting wind passing between the fixed fins 52. Also, the second object placed on the movable fin 51 and the fixed fin 52 is less likely to be scattered by the sorting wind passing between the movable fin 51 and the fixed fin 52. Therefore, this threshing sorter 1 can raise the sort rate of a processed material.

  As described above, the threshing and sorting apparatus described above includes the upper and lower two-stage chaff sheave as the leakage sorting section, but a grain sheave may be used instead of the upper-stage chaff sheave.
