However, in such a combine, the guide plate is fixedly attached to the outlet of the cross-flow fan, so that the cross-flow fan sucks to the rear of the fuselage (the sorting part) The sorting air that flows substantially linearly toward the rear part contacts the guide plate inclined in the left-right direction at the outlet of the cross-flow fan, and this guide plate obstructs the suction wind speed. As a result, the direction of air flow from the front to the rear of the sorting air in the sorting section changes, resulting in poor sorting due to wind sorting of the mixture, third loss, dust retention and accumulation, etc. was there.
Accordingly, an object of the present invention is to adjust the direction of installation of the direction plate according to the amount of the mixture (grain) in the sorting unit, thereby making it possible to adjust the suction air speed of the cross-flow fan, and sorting by wind sorting in the sorting unit. The object is to provide a combine with improved efficiency.

  For this reason, the invention according to claim 1 includes a harvesting unit that harvests cereals, a threshing unit that threshs cereals harvested by the harvesting unit, and a selection unit that sorts the grains threshed by the threshing unit. And the sorting unit wind-sorts the mixture containing the grains falling through the chaff sheave and the grain sieve from the cereal plate arranged at the front part of the sorting unit into the first and second items. For supplying the sorting air for adjusting the air volume according to the amount of the mixture based on the detection information by the means for detecting the amount of the mixture; The cross flow fan for sucking the sorting wind from the tang is arranged, and the outlet is obtained by changing the wind direction of the sorting wind and wind-selecting the mixture by the wind sorting. Equipped with a direction plate that discharges waste in one direction outside the machine In that combine, the direction plate, depending on the amount of mixture is detected by the detecting means, characterized in that it comprises freely movable.

  According to a third aspect of the present invention, in the combine according to the first aspect, the direction plate rotates in conjunction with the opening / closing of the Kara shutter based on the amount of the mixture detected by the detecting means. To do.

  According to the first aspect of the present invention, there is provided a reaping part for reaping cereals, a threshing part for threshing cereals harvested by the reaping part, and a selection part for selecting the grains threshed by the threshing part. The sorting unit is arranged at the front part of the sorting unit for wind-sorting the mixture containing the grains falling from the cereal plate and passing through the chaff sieve and the grain sieve into the first and second ones. From the tang which supplies the sorting air by adjusting the air volume according to the amount of the mixture based on the detection information by the detecting means of the amount of the mixture, and from the tang which is located behind the tang and located at the outlet at the rear of the sorting section. And a cross-flow fan for sucking the sorted air, and changing the wind direction of the sorted air at the discharge port so that the exhaust gas obtained by wind-selecting the mixture by wind sorting is sent in one direction outside the machine. In a combine comprising a direction plate to be discharged, the direction plate Since it is movably provided according to the amount of the mixture detected by the detecting means, the direction plate is slid according to the detection information by the detecting means of the mixture amount, and the suction air direction of the discharge port is changed, so that the selection by the cross flow fan is performed. By adjusting the suction speed of the wind and efficiently sorting the mixture according to the amount of the mixture in the sorting section, it is possible to surely remove dust and generated dust. Therefore, it is possible to provide a combine in which the suction air speed of the cross-flow fan is adjusted according to the amount of the mixture in the sorting unit and the sorting efficiency by the wind sorting in the sorting unit is improved.

  According to the second aspect of the present invention, the direction plate moves up and down in conjunction with the opening and closing of the red pepper shutter based on the amount of the mixture detected by the detecting means. When the air volume is increased, the direction plate is lowered (stored) to reduce the obstruction of the air path at the discharge port, and the suction speed of the air to be selected by the cross-flow fan can be increased. It is possible to efficiently wind-sort the mixture and reliably remove the dust and generated dust by suction. In contrast to the above, when the amount of grain in the sorting unit is small, the opening of the red pepper shutter is reduced, and the sorting air volume is reduced, the sorting air path at the outlet is raised by raising the direction plate. Can be reduced, the suction wind speed of the sorting wind by the cross-flow fan can be lowered, and the grains that can be sorted and collected can be prevented from being discharged out of the machine. Therefore, it is possible to provide a combine that can adjust the suction air speed of the cross-flow fan in conjunction with the hot air shutter that adjusts the air volume of the hot air, and improves the sorting efficiency by the wind sorting of the sorting section.

  According to the third aspect of the present invention, the direction plate rotates in conjunction with the opening and closing of the red pepper shutter based on the amount of the mixture detected by the detecting means, so that the amount of grain in the sorting unit is large and the red pepper shutter is opened. When the air flow is increased, the direction plate is rotated to a position substantially parallel to the air flow direction of the air to reduce the obstruction of the air flow at the discharge port, and the cross flow fan selects the air flow. The suction speed of the wind can be increased, and the mixture can be efficiently screened, and the dust and generated dust can be reliably removed by suction. Contrary to the above, when the grain amount in the sorting unit is small, the opening of the red pepper shutter is reduced, and the sorting air volume is reduced, the direction plate is tilted in the left-right direction with respect to the wind direction of the sorting wind. By doing so, it is possible to increase the obstruction of the sorting air path at the discharge port, reduce the suction speed of the sorting wind by the cross flow fan, and prevent the grain that can be sorted and collected from being discharged out of the machine. Therefore, it is possible to provide a combine that can adjust the suction air speed of the cross-flow fan in conjunction with the hot air shutter that adjusts the air volume of the hot air, and improves the sorting efficiency by the wind sorting of the sorting section.

It is possible to prevent scattering to the barrel supply start end portion 161, guide to the dust feed valve 124 side, and guide to the end portion side of the handling chamber 121. And conventionally, the grain etc. which have been scattered to the barrel supply start end portion 161 can be collected, and the loss can be reduced.

  Next, a specific configuration of the direction plate that is movably provided in conjunction with opening and closing of the red pepper shutter depending on the grain amount of the sorting unit will be described. FIG. 6 is a schematic diagram of the left side of the tang, FIG. 7 is a linkage diagram of the tang and the mixture amount detecting means, FIG. 8 is a schematic diagram of the left side of the cross flow fan and the cross flow fan, and FIG. FIG. 10 is a schematic rear view of the left side of the fan, FIG. 10 is a schematic rear view of the direction plate in FIG. 9, FIG. 11 is a schematic rear view of the direction plate showing lifting by the motor, and FIG. FIG. 13 is a schematic diagram of the back of the plate, FIG. 13 is a diagram of the linkage between the red shutter and the direction plate, and FIG. 14 is a schematic diagram of the back of the vicinity of the discharge port showing the direction plate that can rotate.

  First, as shown in FIG. 6, the above-described Karatsu 132 has a support shaft 212 installed in the left-right direction in the fan casing 211, and a large number of fans 213 are radially attached to the peripheral surface of the fan support shaft 212. By rotating the support shaft 212 with a motor (not shown) or the like, the fan 213 is rotated, and the air sucked from the intake port 214 opened to the left side of the fan casing 211 is blown rearward as a selection air, The mixture leaked into the sorting unit 130 is wind sorted.

  Further, for example, as shown in FIG. 7, one or a plurality of thermostud type wind speed sensors or the like as the mixture amount detecting means 215 are provided from the upper front of the first conveyor 141 to the vicinity of the upper portion of the second conveyor 142. The mixture amount detecting means 215 is connected to the controller C while being disposed. The mixture amount detection means 215 is not limited to the thermostud type wind speed sensor described above, and the mixture amount detection means 215 by an appropriate method can be installed at an appropriate position.

  Next, the fan casing 211 of the carp 132 is pivotally supported by a support shaft 218 whose axis is directed in the left-right direction via a support piece 217 via a support piece 217, which adjusts the opening amount of the air inlet 214. The red pepper shutter 216 is rotatable in the vertical direction. An arm 219 is attached to the support shaft 218, and the arm 219 is connected to the motor 221 via a wire 220 or the like. The motor 221 is connected to the controller C.

  In such a configuration, when the amount of grain (mixture amount) leaked to the sorting unit 130 is large, these grains prevent the backward flow of the sorting wind from the Karatsu 132, so that the entire mixture is sorted. The necessary wind power is insufficient. Therefore, the controller C operates the motor 221 based on the detection information that the mixture amount detection means 215 detects that the selected air volume is small at the installation position, and the front end of the arm 219 is illustrated via the wire 220. 7, the rear portion of the red pepper shutter 216 is rotated around the support shaft 218 in the clockwise direction when viewed from the left side, and the air flow of the sorting wind in the red pepper 132 is increased. The red pepper shutter 216 can be configured to open at an angle corresponding to the grain amount between the closed position c and the fully opened position d based on the detection information of the mixture amount detection means 215. Therefore, the red pepper 132 can maximize the air flow rate by rotating the red pepper shutter 216 to the position d.

  Contrary to the above, when the amount of the mixture leaked to the sorting unit 130 is small and the sorting wind from the red pepper 132 blown backward is strong due to less shielding by the grains, the sorting and recovery in the mixture Even the grain that should be scattered will be scattered and discharged by the strong sorting wind, resulting in third loss. For this reason, the controller C operates the motor 221 based on the detection information that the mixture amount detection means 215 detects that the selected air volume is large at the installation position, and the front end of the arm 219 is connected via the wire 220. By rotating downward, the rear portion of the red pepper shutter 216 is rotated counterclockwise when viewed from the left side about the support shaft 218, and the rotary shutter 216 is rotated in the closing direction. To prevent third loss and so on. Note that the red pepper shutter 216 can be configured to close at an angle corresponding to the amount of the mixture between the position c and the position d based on the detection information of the detection means 215.

  The configuration of the sorting unit 130 that can adjust the air flow rate of the sorting wind generated from the tang ridge 132 as described above is a well-known technique described in, for example, Japanese Patent Application Laid-Open No. 2004-65247. As described above, even if the tangential shutter 216 is fully opened and the air flow of the sorting air is increased in accordance with the amount of the mixture in the sorting unit 130, the sorting air sucked by the cross flow fan 140 is removed from the outlet 200 by the sorting air. Since the contact is made with the direction plate 205 inclined in the left-right direction with respect to the wind direction, the suction wind speed of the sorting wind by the cross flow fan 140 is decelerated at the discharge port 200. As a result, it is not possible to exhaust a part of the sorting air blown from the Kara 132 at the discharge port 200, and the flow of the sorting wind from the front to the rear changes in the sorting unit 130, resulting in convection and the like. As a result, the sorting efficiency of the sorting unit 130 has deteriorated, such as stagnation and dust that cannot be removed by suction and remain. Therefore, the present invention has an exhaust flow by the cross flow fan 140 on the suction side of the sorting air, in addition to the configuration of the Kara 132 that makes it possible to adjust the air flow rate according to the amount of the mixture leaked to the sorting unit 130 as described above. The suction wind speed (suction air volume) can be adjusted by the direction plate 205.

  First, as shown in FIGS. 4 and 8 to 9, the crossflow fan 140 is disposed at the rear end of the sorting unit 130 and inside the discharge port 200 at the rear of the machine body. This cross flow fan 140 has a horizontally long shape in the left-right direction, and is installed with the rotating shaft 204 mounted on the left and right side walls 205. A plurality of wind generating plates 206 are provided on the outer peripheral surface of the cross flow fan 140 substantially in parallel in the left-right direction.

  Further, above the cross flow fan 140, the cross flow fan 140 is covered from above, the upper fan casing 201, and the cross flow fan 140 also below the rear part of the cross flow fan 140 so as to cover from below, A lower fan casing 202 having a tongue 203 connected to the front is fixedly attached with left and right ends attached to the left and right side walls 205, respectively. The lower fan casing 202 also serves as a shielding plate. The lower fan casing 202 is caused to collide with the lower fan casing 202 by causing the mixture containing the grains scattered by the sorting unit 130 to the lower side of the rear cross flow fan 140 by the sorting wind. It is guided into the dynamic sorting device 131.

  Next, as shown in FIGS. 9 to 10, the upper part in the discharge port 200, as shown in FIGS. 9 to 10, is attached to the upper part with welding or a fastener such as a bolt. Three directional plates 205 in the drawing are projected downward. The direction plate 205 is inclined with respect to the wind direction of the sorting wind flowing from the front to the rear in the sorting unit 130 by tilting the front portion of the direction plate 205 to the left side of the body and the rear portion to the right side of the body. .

  The number of directional plates 205 installed is not limited as described above, but it is preferable to install a plurality of directional plates 205 in order to reliably change the wind direction of the sorting wind. In that case, the respective direction plates 205 are installed substantially in parallel at equal intervals.

  Next, as shown in FIGS. 11 to 12, each direction plate 205 has a double structure of an external direction plate 205 a and an internal direction plate 205 b that can move up and down in the external direction plate 205 a up and down. Is done. For example, as shown in FIG. 11, the inner direction is set in the concave portion 207 of the external direction plate 205a having a concave portion 207 in the rear view and having a concave portion 207 inside as shown in FIG. A plate 205b is fitted. The height of the external direction plate 205a may be about 1/4 of the height of the discharge port 200. Further, when the internal direction plate 205b is protruded most downward (the lower end of the internal direction plate 205b is at the position a), the lower end of the internal direction plate 205b is the center of the height of the discharge port 200. It is set as the internal direction board 205b which has the height of the grade located in the vicinity. Further, the height of the external direction plate 205a is such that when the internal direction plate 205b is accommodated most deeply (the lower end of the internal direction plate 205b is at the position b), the lower end of the internal direction plate 205b is the lower end of the external direction plate 205a. You may make it the height which is located in.

  In addition, a motor M1 connected to the controller C shown in FIG. 13 is installed on the upper fan casing 201, and in the recess 207, between the motor M1 and the upper end of the internal direction plate 205b, the motor An arm 208 that can be expanded and contracted is connected by M1. The installation of the motor M1 is not limited to the position described above.

  Here, when the cereals harvested by the harvesting unit 7 are conveyed to the threshing unit 4 and the mixture containing the grains threshed by the threshing unit 4 leaks to the sorting unit 130, the amount of the mixture as described above If there is a large amount, the controller C activates the motor 221 based on the detection information that the mixture amount detection means 215 detects that the selected air volume is small at the installation position, and the front end of the arm 219 is connected via the wire 220. By rotating upward, the red pepper shutter 216 rotates about the support shaft 218 in the clockwise direction when viewed from the left side, and the red pepper shutter 216 is opened at an appropriate angle to increase the air flow rate of the sorting wind in the red pepper 132. .

  At this time, the controller C operates the motor M1 together with the motor 221 to slide the arm 208 upward. For this reason, the internal direction plate 205b is accommodated in the recess 207 of the external direction plate 205a, and the lower end of the internal direction plate 205b rises to an appropriate position toward the position b.

  As a result, in the discharge port 200, the internal direction plate 205b protruding downward from the external direction plate 205a is accommodated in the concave portion 207 of the upper external direction plate 205a, so that the direction plate 205 contacts the sorting air. Even if the area is small and the external direction plate 205a is inclined to the left and right with respect to the wind direction of the sorting wind, the height of the external direction plate 205a is low, so there is less obstruction of the air path for changing the wind direction of the sorting wind. As a result, the suction air speed of the cross flow fan 140 increases. The internal direction plate 205b is raised in proportion to the appropriate position between the position a and the position b according to the opening degree of the red shutter 216 based on the detection information of the mixture amount detecting means 215, The plate 205 can be made high according to the grain amount. Therefore, the crossflow fan 140 has the maximum suction wind speed by sliding the lower end of the internal direction plate 205b to the position b.

  With such a configuration, when the red pepper shutter 216 is opened to increase the air flow rate of the red pepper 132 in accordance with the increase in the grain amount of the sorting unit 130, the internal direction plate 205b is moved upward in conjunction with the rotation of the red pepper shutter 216. Can be accommodated in the external direction plate 205a and the suction air speed of the cross flow fan 140 can be increased, so that the selected air blown by the Kara 132 can be sucked more by the cross flow fan 140. Maintaining the flow of the sorting wind from the front to the rear in the sorting unit 130 to prevent the occurrence of convection, and reliably sucking and removing the dust and dust to improve the sorting efficiency of the sorting unit 130 Can do.

  Contrary to the above, when the amount of the mixture leaked to the sorting unit 130 as described above is small, the mixture amount detection means 215 is based on the detection information detected that the sorting air volume is large at the installation position. The controller C operates the motor 221 to rotate the front end portion of the arm 219 downward via the wire 220, so that the rear portion of the Kara shutter 216 rotates counterclockwise around the support shaft 218 as viewed from the left side. Then, the red pepper shutter 216 is rotated in the closing direction to reduce the air flow of the sorting air in the red pepper 132.

  At this time, the controller C operates the motor M1 together with the motor 221 to slide the arm 208 downward. For this reason, the internal direction plate 205b protrudes downward from the inside of the recess 207 of the external direction plate 205a, and the lower end of the internal direction plate 205b descends to an appropriate position toward the position a.

  As a result, in the discharge port 200, the internal direction plate 205 b accommodated in the recess 207 of the external direction plate 205 a is protruded downward to increase the overall height of the direction plate 205. The area of contact with the sorting air increases, and the obstruction of the air path for changing the direction of the sorting wind increases, so that the suction air speed of the cross flow fan 140 decreases. For this reason, while the amount of the mixture in the sorting unit 130 is small, the sorting air volume from the red pepper 132 blown backward is reduced, and the suction air volume of the sorting air by the cross flow fan 140 is reduced, so that the third loss, etc. Can be reliably prevented.

  The internal direction plate 205b is lowered in proportion to the appropriate position between the position b and the position a according to the opening degree of the red shutter 216 based on the detection information of the mixture amount detection means 215, and the direction The plate 205 can be made high according to the grain amount. Accordingly, the crossflow fan 140 has the suction air velocity minimized by sliding the lower end of the internal direction plate 205b to the position a.

  In addition to the above, the internal direction plate 205b can be raised and lowered by, for example, a wire. In this case, for example, as shown in FIG. 12, concave and convex engaging portions 235 are provided in the left and right inner portions in the recess 207 in the outer direction plate 205a, and notches are formed in the upper left and right outer portions in the inner direction plate 205b. 209 is provided. The notch 209 contracts inward (inner direction plate 205b side) against the urging of the elastic member 209a such as a spring by external pressure, but when released from the external pressure, the notch 209 is restored to the original side by urging the elastic member 209a. It is set as the structure which protrudes and returns to a direction position. Further, one end of the wire 210 is attached to an appropriate position such as the upper end portion of the internal direction plate 205b, and the other end of the wire 210 is connected to the motor 221.

  With such a configuration, in the same manner as described above, the controller C operates the motor 221 to open and close the red shutter 216 according to the amount of mixture leaked to the sorting unit 130 based on the detection information of the mixture amount detecting means 215, and The same effect as described above can be obtained by sliding the wire 210 and raising and lowering the internal direction plate 205b. And when this internal direction board 205b raises / lowers, since the engaging part 235 engages with the notch 209 in the raising / lowering position suitably, it can hold | maintain in the raising / lowering position of the internal direction board 205b. The sliding amount of the wire 210 corresponds to the opening / closing angle (sliding amount of the wire 220) of the red pepper shutter 216 according to the grain amount by the mixture amount detecting means 215, so that the opening / closing angle of the red pepper shutter 216 and the internal direction Both can be operated in proportion to the elevation position of the plate 205b.

  Further, the amount of exhausted air can be adjusted by rotating the installation position of the direction plate 205. In this case, for example, as shown in FIG. 14, each direction plate 205 is rotatable in the left-right direction of the machine body by a rotation fulcrum shaft 231 provided in the middle part thereof. The pivot fulcrum shaft 231 is pivoted with its upper end protruding from the upper fan casing 201.

  In addition, each direction plate 205 has a front end portion attached to the linkage 232 at equal intervals, and the rotation fulcrum shaft 231 of any one direction plate 205 (the left-end direction plate in FIG. 13) includes An interlocking arm 233 is provided. Further, one end of the wire 234 is attached to the rear portion of the interlock arm 233, and the other end of the wire 234 is connected to the lower portion of the arm 219.

  With such a configuration, similarly to the above, the controller C operates the motor 221 to slide the wire 220 and slide the arm 219 according to the amount of mixture leaking to the sorting unit 130 based on the detection information of the mixture amount detecting means 215. Is rotated to open and close the red shutter 216. At this time, the wire 234 slides according to the rotation of the arm 219. That is, the wire 234 is pulled to the arm 219 side (the Karatsu shutter 216 side) by the rotation of the arm 219 which is the direction to open the Karatsu shutter 216, thereby rotating the interlocking arm 233 clockwise as viewed from the back.

  As a result, the left end direction plate 205 is rotated from the position e toward the position f in the longitudinal direction of the machine body with the rotation fulcrum shaft 231 as the center, so that the other direction plate 205 is also connected to the left end via the linkage 233. All the direction plates 205 rotate in parallel with the direction plate 205. As a result, the wind direction of the sorting air and the arrangement of the direction plate 205 are substantially parallel, thereby reducing the contact area of the sorting air to the direction plate 205 and weakening the hindrance to the flow of the sorting air, so As the selected air volume increases from the above, the suction air speed of the cross flow fan 140 is increased, and the same effect as described above can be obtained. The direction plate 205 can maximize the suction air velocity of the cross flow fan 140 at the position f.

  Contrary to the above, the wire 234 is pushed toward the direction plate 205 by the rotation of the arm 219 which is the direction in which the red shutter 216 is closed, thereby rotating the interlocking arm 232 counterclockwise when viewed from the back. As a result, the direction plate 205 at the left end is rotated toward the position e in the left-right direction of the machine body (the rear part of the direction plate 205 is the right direction of the machine body) around the rotation fulcrum shaft 231. All the direction plates 205 rotate in parallel with the left-direction direction plate 205 via the flange 233. As a result, by using the direction plate 205 inclined in the left-right direction with respect to the wind direction of the sorting wind, the contact area of the sorting wind to the direction plate 205 is increased and the hindrance to the flow of the sorting wind is strengthened. As the selected air volume decreases, the suction air speed of the cross flow fan 140 can be reduced, and the same effect as described above can be obtained. The direction plate 205 can minimize the suction air speed of the cross flow fan 140 at the position e.

  Then, by making the sliding amount of the wire 234 proportional to the rotation amount of the arm 219, the direction plate 205 may be rotated to an inclination angle corresponding to the open / close angle of the red shutter 216. At this time, the fully open position d of the red shutter 216 is set to the position f of the direction plate 205.

  In the above description, the connection destination of the wire 234 is the arm 219. However, even if the connection destination is the motor 221, the same effect as described above can be obtained.

  Further, as described above, the direction plate 205 is opened and closed in conjunction with the opening and closing of the red shutter 216. However, the present invention is not limited to this, and the detection information of the mixture amount detection means 215 is detected. The controller C may operate the wire 234 via the motor 221 and adjust the installation angle of the direction plate 205 according to the amount of mixture leaking to the sorting unit 130 based on the above. This is effective in cases where it is not possible to adjust the air volume of the red pepper 132, or when it is desired to wind the mixture while keeping the air volume of the red pepper 132 constant, and the same effects as described above can be obtained.

  As described above in detail, the combine 1 of this example includes a harvesting unit 7 that harvests cereals, a threshing unit 4 that threshs cereals harvested by the harvesting unit 7, and a grain that has been threshed by the threshing unit 4. A sorting unit 130 for sorting, and the sorting unit 130 is arranged at the front of the sorting unit 130, and includes a mixture containing grains that fall from the flown cereal plate 135 through the chaff sheave 138 and the grain sheave 137.

It is to be prepared.

  In addition, the direction plate 205 moves up and down or rotates in conjunction with the opening and closing of the shutter 216 of the red pepper 132 based on the amount of the mixture detected by the detecting means 215.

  As described above, the direction plate 205 is provided at equal intervals with respect to the entire width of the cross flow fan 140 disposed inside the sorting waste discharge port 200.
