In recent years, however, there has been a demand for further downsizing (compacting) of the combine, but the following problems have been encountered in the case where the grain passing reduction vessel is disposed so as to intersect with each other when viewed from the side as in the combine of Patent Document 1. That is, as described above, since the grain passing and reducing tubes are intersected with each other when viewed from the side, it is necessary to widen the interval between the threshing device and the grain tank by an amount occupied by the space in the right and left width directions of the both cylinders. Therefore, there is a problem in that it is difficult to cope with the above-mentioned demand for compactness because the side width dimension of the combine must be made larger than the left-right width dimension of the threshing device and the grain tank.
However, in the structure of Patent Document 1, the transfer and dispersion of the second water returned from the reprocessing apparatus is mainly performed by the oscillating motion of the oscillating screening unit. Due to the relationship between the opening direction of the reprocessing device and the rotation direction of the reprocessing motion coin, the rotation of the reprocessing motion does not contribute much to dispersing the two objects on the swinging screen. Because of this, the second item from the reprocessing apparatus is liable to deviate right under the discharge port of the reprocessing apparatus. Furthermore, the debris thrown away by the swinging of the threshing device is more likely to fall off toward one side of the downstream side of the swinging motion rotation than the left and right center portions of the swinging motion-detecting screen. Therefore, in the swing sorting half, the grains and the second article tend to be concentrated and deposited on one side near the downstream side of the swing motion (near the direct lower side of the swinging mouth), and the ability to sort out the debris and the second swirl in the swinging- And there was a possibility of causing the third row or poor selection.

Therefore, it is possible to secure a sufficient distance for the second article to move within the apparatus for reprocessing (re-threshing), thereby improving the reprocessing function of the second article by the reprocessing operation.
According to the invention of claim 2, the grazing device and the second reducing device are arranged longitudinally in the forward and rearward order of the graining device and the second reducing device between the gravity tank and the grain tank, And the second reducing apparatus, the reprocessing apparatus is positioned so as to overlap the area of the feed chamber of the threshing apparatus when viewed from the side, so that the width of the toning apparatus, the second reducing apparatus, The space occupied can be reduced, and the grain machine, the second reducing device and the reprocessing device can be arranged compactly between the trolley and the grain tank. Therefore, it is possible to enlarge the space occupied in the left and right width directions of the above-described threshing device and the above-mentioned grain tank without enlarging the lateral width direction of the combine, and the threshing ability and the grain storage ability can be improved without increasing the size of the combine.
Further, as described above, since the reprocessing device is positioned so as to overlap the area of the feed room of the threshing device when viewed from the side between the gravity device and the second reducing device, the second processed product It is possible to return smoothly into the feed chamber of the threshing device without scattering it with no operation. Therefore, it becomes possible to secure a sufficient distance for the second item to be processed while being sorted in the above-described threshing device, and to contribute to improvement of the sorting ability of the combine.
According to a third aspect of the present invention, the lower part of the reprocessing device communicates with the threshing device through a second burner, and is provided at a front side of a supporting frame for supporting a supporting net on a side wall of the threshing device, It is possible to smoothly guide and discharge the processed second object from the discharge port of the second burner to the front side in the trolley without sputtering the treated second burner. Therefore, it is possible to suppress the possibility that the processed second article is locally deposited, for example, in the vicinity of the second burned-out portion, and further contributes to improvement of the sorting capability of the combine.

Therefore, the sorting process can be performed while suppressing the husking or smashing of the second water subjected to the treatment by the collision with the above-mentioned tumbling or the like. In addition, the second burning part formed to have a narrower left and right width toward the front is extended forward by using a clearance space between the threshing device and the grain machine. Therefore, it is possible to distribute the processed second material in the threshing device widely and to discharge it. Further, since the second burning discharge portion is inclined to approach the threshing device as it goes downward, the second burned material that has been treated smoothly through the second burning discharge portion can be guided from the lower portion of the reworking device.

For this reason, each of the treated teeth and each of the receiving teeth is required to have a function of grinding and untwisting the clay kernel and the stack of rice straw, so that the second water conveying function becomes unnecessary. Therefore, the respective processing teeth and each of the receiving teeth can be made to have a simple structure without reducing the re-processing (re-treading) capability.
According to the invention of claim 7, since each of the receiving teeth protrudes to the outer surface side of the reprocessing device and constitutes the strength member of the reprocessing device, It also plays a role. Therefore, the rigidity of the reprocessing apparatus can be improved.

Therefore, it is possible to smooth the succession of the second water from the second reducing device to the reprocessing device, to prevent the stay at the time of succession, and to prevent the clogging between the second reducing device and the reprocessing device . It is also possible to reliably prevent the rotation of the scraper plate from interfering with the succession of the second water when the second item is conveyed to the reprocessing apparatus side through the upper conveying port. Therefore, the second object can be transferred smoothly in the reprocessing apparatus. In addition, it is possible to suppress the winding and detachment of the straw debris from the relationship between the presence of the scraper plate and the guide / insertion direction of the second water to the upper portion of the reprocessing.
According to the invention of claim 9, since the scraper plate extends from the upper inner surface to the lower inner surface of the reprocessing apparatus, and a plurality of processing teeth are attached to the scraper plate at a position lower than the upper transfer port, It is possible to stably support the respective processed teeth while suppressing the winding and demolding of the straw debris into the whole of the reprocessed copper.

Fig. As described above, the threshing device 5 is provided with the tilting action 51, the swinging-sorting plate 52, the tuyet fan 53, and the defrosting fan 61. A feed chamber 173 partitioned by a front partition wall 174 and a rear partition wall 175 is provided above the swinging and sorting tray 52 of the threshing device 5. [ The swash plate 51 is located between the front and rear partition walls 174 and 175 and the swash plate rotation shaft 158 is rotatably supported on both the partition walls 174 and 175. [ A feed port 176 is formed below the front partition wall 174 to feed the end of the cutting gap between the feed chain 6 and the feed chain 6 at the lower part of the rear partition wall 175, And a hungry spout 177 for discharging the end of the end of the cut straw (discharge straw) is provided.
A support frame 178 surrounding the roughly lower half of the rake 51 is attached to the side of the feed chamber 173 remote from the feed chain 6 (on the side of the grain tank 7) A crimp net 60 is laid down. The front and rear lengths of the support frame 178 are set shorter than the front and rear lengths of the supply chamber 173, that is, the arrangement intervals of the front and rear partition walls 174 and 175. The supporting frame 178 of the embodiment has the front portion attached to the front partition wall 174 side and the rear portion disposed in the middle chamber 173 away from the rear partition wall 175 side. Therefore, an opening space opened rearwardly and downwardly is formed between the support frame 178 and the rear partition wall 175, and the opening space serves as a hung hole 177 in the rear portion of the middle chamber 173.
In this case, the tip end side of the cut-away curved portion sandwiched and conveyed by the feed chain 6 enters from the supply port 176 located below the front partition wall 174 into the supply port 173, 60, and is discharged from the hatch opening 177 located below the rear partition wall 175 toward the hung chain 62.

The straw rack 186 is disposed at the rear side of the chaff sheave 184. A hung plate 187 is provided below the hung hole 177 on the upper surface side of the chaff sheave 184. On the rear side of the hung plate 187, a plurality of body lines 188 for guiding the debris to the rear and toward the center of the body are attached.
The grains which have been thrown by the sweep 51 and leaking from the crimp net 60 fall on the feed pan 183 of the oscillating screening tray 52 which reciprocates and are swinged (sorted by gravity) (184). The grains on the chaff sheave 184 are swung by the chaff sheave 184 itself and receive a sorting air flowing rearward from the tuyere pan 53. [ The decolorized grains are separated into grains and straw debris by such sway sorting and balloon interaction.
The feed fan 183 of the embodiment has a plate shape inclined rearwardly obliquely downward from the front right side (the front portion near the curling tank 7) toward the rear left portion (the rear portion near the feed chain 6) . The debris that has been tilted by the ramp 51 by the inclined surface is rolled (spread) toward the feed chain 6 on the feed fan 183.
The first articles dropped from the chaff sheave 184 and the grain sheave 185 are gathered at the position of the first conveyor 55 while the dust therein is removed by the air flow from the tuyere pan 53. [ The second item that could not pass through the chaff sheave 184 and the grain sheave 185 drops from the straw rack 186 and is collected at the position of the No. 2 conveyor 56 at the rear of the No. 1 conveyor 55. Further, the relatively light straw crumb on the chaff sheave 184 is sucked into the evacuation fan 61 and discharged out of the apparatus through the suction discharge port 189 formed at the rear thereof. The relatively heavy straw debris on the chaff sheave 184 is discharged to the outside of the apparatus through the swinging outlet 190 (the so-called third row) formed on the rear side of the swinging and sorting plate 52 via the straw rack 186.
(4). Wind structure of selective wind
Next, referring to Fig. 7, a wind path structure of a sorting wind to be supplied from the tug fan 53 to the chives sheave 184 will be described. Here, the torn air fan 53 of the embodiment is configured to be rotationally driven in the counterclockwise direction in Fig. The fan case 200 of the tuyere fan 53 is provided with a primary air passage 201 for supplying the grain air to the grain sheave 185 and the No. 1 conveyor 55 at the tuyere fan 53, A first pre-air passage 202 for supplying a selective air of the tuyere fan 53 to the upper surface side of the chaff sheave 184 from between the rear end side and the front end side of the chaff sheave 184, A second pre-air passage 203 for supplying the air to the till fan 53 is formed on the lower surface of the chaff sheave 184 from between the front-end side of the chaff sheave 184 and the grain fan 191 on the front side.
The primary air passage 201 is formed in such a manner that the sorting air from the tuyeres fan 53 is moved from the front lower side to the rear upper side of the grain sheave 185 via the upper surface side of the main airfoil 204. The primary air passage 201 described above is so formed that the selective air from the tuyere fan 53 is moved from the front side to the rear side of the No. 1 conveyor 231 via the lower side of the main airfoil 204 have. That is, the curling and the dust falling from the grain sheave 185 to the No. 1 conveyor 55 are blown by the selective wind from the tuyere fan 53.
The first pre-air passage 202 is arranged so that the selective wind from the tuyere fan 53 passes through the upper surface side of the pre-wind deflector 205 installed on the swinging-screening tray 52 from the front side to the rear side on the upper side of the chaff sheave 184 Respectively. That is, when the debris falling from the elevation 51 to the upper surface of the feed fan 183 through the crimp net 60 falls from the rear end side of the feed fan 183 to the front end side of the chaff sheave 184, (53).
The second pre-air passage 203 is formed so that the sorting wind from the tuyere fan 53 is moved from the front side to the rear side of the grain pan 191 via the lower side of the pre-wind deflector 205. In other words, the second pre-air passage 203 is formed so as to move the sorting wind from the tug fan 53 from the front lower side of the chaff sheave 184 toward the rear upper side of the chaff sheave 184. That is, the grain air and the dust falling from the chaff sheave 184 to the grain pan 191 and the grain sheave 185 are blown by the selective wind from the tuyere fan 53.
In this case, among the grains moved to the upper surface of the chaff sheave 184, the straw debris (light weight) on the lower side of the dehydrated material near the upper surface of the chaff sheave 184 is conveyed to the upper side by the selective air, The amount of straw crumbs to be dropped is reduced. Further, the grains (heavy matter) on the upper layer side of the debris are moved to the lower side by the specific gravity selecting operation of the chaff sheave 184 and the balloon of the screening wind from the tearing fan 53, and are led from the chivesheet 184 at an early stage. The specific gravity separating action of the chaff sheave 184 is promoted by the sorting wind from the tuyere fan 53 to improve the sorting performance (sorting accuracy).
The selective air from the primary air passage 201, the first pre-air passage 202 and the second pre-air passage 203 is sucked into the above-described discharge fan 61, 189, or discharged from the swing outlet 190. As a result, straw debris and dust in the debris are discharged from the back of the thresher housing 180 to the outside of the apparatus.
(5). Detailed structure of No. 2 reducing device and reprocessing device
Next, the detailed structure of the No. 2 reducing apparatus and the re-processing apparatus 59 will be described with reference to Figs. 6 to 12. Fig. The second reducing device composed of the reducing cylinder 58 and the reducing conveyor 160 is for returning the second piece after the threshing and sorting to the threshing device 5. On the conveying end side of the No. 2 reducing device (reducing cylinder 58), there is provided a reprocessing device 59 for reprocessing the No. 2 product. The reduction cylinder 58 is supported along the outer surface of one side wall of the thresher housing 180 (in the embodiment, the right side wall 180a) in a longitudinally inclined posture slightly forward. The reduction conveyor 160 is rotatably disposed in the reduction cylinder 58. (Lower end side) of the reducing conveyor 160 is connected to the conveying end portion protruding outward from the right side wall 180a of the thresher housing 180 among the No. 2 conveyor 56 so as to transmit power.
As shown in Figs. 6 to 11, an aqueous case 210 is disposed on the outer surface of the right side wall 180a of the thresher housing 180. As shown in Fig. And the lower end side of the reduction cylinder 58 is connected to the upward opening side of the water system case 210. [ The reducing cylinder 58 and the grain cylinder 57 are arranged between the threshing device 5 and the grain tank 7 so as to extend in the longitudinal direction. In this case, they are arranged in such a manner as to extend parallel to each other in the order from the front side in the forward direction of the traveling base 1 to the valley cylinder 57 and the reduction cylinder 58.
The right end side of the second shaft 211 of the No. 2 conveyor 56 and the lower end side of the reduction shaft 212 of the reduction conveyor 160 are respectively rotated (rotated) by the bearing 210 So that it is supported as much as possible. The right end side of the second shaft 211 and the lower end side of the reduction shaft 212 are connected via a bevel gear mechanism 213. The transfer end side (upper end side) of the reduction shaft 212 is rotatably supported on a case body 231 of the drive case 230 that covers the transfer longitudinal section (upper end surface) of the reduction cylinder 58. The second item dropped from the straw rack 186 to the second conveyor 56 is transferred from the second conveyor 56 to the reduction conveyor 160. [ The second item transferred to the reduction conveyor 160 is re-processed from the reduction conveyor 160 by the raking out blade 214 provided on the conveying end side of the reduction shaft 212 (161). In addition, the reduction conveyor 160 of the embodiment is configured to be rotationally driven in the counterclockwise direction around the reduction shaft 212 in Fig.
The conveying end side of the reducing cylinder 58 and the right side wall 180a of the thresher housing 180 communicate with each other through the reprocessing device 59 and the second burning unit 215. The reprocessing device 59 is attached to the conveying end side of the reducing cylinder 58 and is disposed between the valley cylinder 57 and the reducing cylinder 58 so as to be located on the side of the feed chamber 173 of the threshing device 5 Are arranged so as to overlap with each other. The reprocessing device 59 is provided with a reprocessing case 216 constituting its outer shape and a reprocessing copper 161 rotatably disposed around the longitudinal axis in the reprocessing case 216. As shown in Figs. 10 and 11, the reprocessing shaft 217, which is the rotation shaft of the reprocessing copper 161, and the reduction shaft 212, which is the rotation shaft of the reduction conveyor 160, extend in parallel. The reprocessing operation 161 of the embodiment is performed in the counterclockwise direction around the reprocessing shaft 217 in FIG. 12 through the pulley / belt transmission mechanism 233 in the drive case 230 Rotation direction].
A second burning part 215 for guiding the second burned product is connected from the reprocessing case 216 to the threshing device 5 below the front part of the reprocessing case 216. 9, 10 and 12, the right side wall 180a of the thresher housing 180 is provided at a lower side of the ramp rotation shaft 158 and at a lower side than the rear side frame 218 of the support frame 178 A communication hole 219 is formed so as to open upwardly and downwardly with respect to the lower surface of the swash plate 51 when viewed from the side in the front portion. The second burner 215 is connected to the outer surface of the right side wall 180a (the side on the side of the grain tank 7) so as to cover the communication hole 219 of the right side wall 180a from the outside.
That is, the upper portion of the rear portion of the second burner 215 communicating with the lower portion of the front portion of the reprocessing case 216 serves as the second inlet 215a of the treated water. The discharge port 215b of the second burning port 215 is connected to the communication hole 219 located on the lower side of the right rotation axis 158 of the right side wall 180a and in front of the rear frame 218 of the support frame 178, On the back side of the crimp net 60 and on the upper side of the feed fan 183 (the front side in the threshing device 5). Therefore, when viewed from the side, the front end side of the discharge port 215b of the second burner 215 is located on the feed fan 183. [ Further, as viewed from the side, the rear end side of the discharge port 215b of the second burner 215 is located on the chaff sheave 184. The second burning portion 215 itself is positioned lower than the nipple rotation shaft 158 and is positioned forward of the rear subframe 218 of the support frame 178 as is clearly shown in Figs.
As shown in FIGS. 8 to 12, the outer shape of the second burner 215 is formed in a funnel shape that diverges forward and diagonally downward, and the right and left sides of the thresher housing 180 180a. The double burner 215 is disposed so as to partially overlap (wrap) the lengthwise portion of the barrel 57 when viewed from the side. That is, the second burner 215 is positioned between the right side wall 180a of the thresher housing 180 and the middle portion of the valley barrel 57.
The second item succeeded to the reprocessing cycle 161 is reprocessed (re-throttled) by the rotational drive of the reprocessing copper 161 and is supplied to the back side of the crimp net 60 via the second- (Toward the front side in the threshing device 5) of the fan 183. Particularly, in the embodiment, the outer shape of the second burner 215 is formed in a funnel shape that slopes downward forward, and is inclined so as to approach the right side wall 180a of the thresher housing 180 as it goes forward and downward And the reprocessed copper 161 is driven to rotate in the counterclockwise direction around the reprocessing shaft 217 in Fig. 12, so that the processed second is discharged from the valley cylinder 57 in the second burner 215, And is discharged from the upper right side of the feed fan 183 located on the front side of the thresher housing 180 toward the upper left side along the inclined inner surface of the vicinity of the thresher housing 180 (see FIG. 12). On the other hand, in Fig. 8 and Fig. 9, the grains that have been tumbled below the swing 51 rotating in the clockwise direction are scattered from the upper left side of the feed pan 183 toward the upper right side.
That is, the scattering direction of the molten material from the rake 51 (the direction from the feed chain 6 side toward the grain tank 7 side) and the scattering direction of the second water from the second burning discharge section 215 ) Toward the feed chain 6 side) intersect near the left and right central portions of the feed fan 183. Therefore, it is possible to collide the grain and the second grain in the vicinity of the right and left central portions of the feed pan 183 and to disperse them, and the grains and the grain can be dispersed in the right side (near the right lower portion of the second grain discharging portion 215) It is possible to prevent the second material from being concentrated and deposited. Also, the grains and the second material, which are pivoted from the feed pan 183 to the chaff sheave 184, can be diffused (dispersed) in the lateral direction of the chaff sheave 184, thereby improving the screening efficiency.
As shown in Figs. 10 to 12, the reprocessing case 216 constituting the reprocessing apparatus 59 is connected to the right side wall 180a of the thresher housing 180 by means of a bolt or the like from the outside, (Box) shape. The upward opening side of the reprocessing case 216 is covered with a drive case 230 for relaying the rotational power of the reduction conveyor 160. A second burner 215 for covering the communication hole 219 of the right side wall 180a from the outside is fixed to the bottom of the front portion of the reprocessing case 216 by welding or the like. The upper side of the rear portion of the reprocessing case 216 is fixed to the opening end side of the U-shaped cover 220 surrounding the outer circumferential side of the scraping blade 214 on the conveying end side of the reducing shaft 212 by bolts and nuts Respectively. A U-shaped cover 220 is fixed to the lower end of the U-shaped cover 220 by welding or the like, with a tubular flange 221 passing through a reduction shaft 212. A ring portion protruding downward from the tubular flange 221 is fitted on the conveying end side of the reducing cylinder 58. The case body 231 of the drive case 230 is bolted to the upper end of the U-shaped cover 220 and the upper end of the reprocessing case 216. A transfer end of the reduction shaft 212 is rotatably supported on a portion of the case body 231 on the U-shaped cover 220 side.
As shown in Figs. 10 and 12, the opening end side of the U-shaped cover 220 on the conveying end side of the reducing cylinder 58 communicates with the upper side of the rear portion of the reprocessing case 216. [ In other words, the opening end side of the U-shaped cover 220 and the upper side of the rear part of the reprocessing case 216 are connected through the upper conveying port 222. The second item transferred to the reduction conveyor 160 is transferred into the reprocessing case 216 on the reverse U-turn when viewed from the side via the upper transfer port 222. [ The peripheral walls 216a and 220a of the upper conveyance port 222, that is, the peripheral wall of the U-shaped cover 220 facing the grain tank 7 on the side of the grain tank 7, The portions 216a and 220a (the portion along the flow direction of the second water) are arranged in a straight line along the common tangent line TL extending over the inner circumference of the reprocessing case 216 and the U- It is held against the prize. The combination of the configuration and the reprocessing copper 161 that is rotationally driven in the counterclockwise direction in Fig. 12 makes it possible to reduce the conveying force by the scraping blade 214 to a very small extent And is smoothly conveyed to the side of the reprocessing case 216 along the peripheral walls 216a and 220a of the upper conveying port 222. [
As shown in Figs. 9, 10 and 12, in the inner surface of the reprocessing case 216 in the vicinity of the threshing device 5, A downwardly inclined guide plate 241 is fixed by welding or the like. A shielding plate 242 for closing the portion of the upper conveying passage 222 near the threshing unit 5 (the inner surface of the U-shaped cover 220 in the vicinity of the threshing unit 5 in the embodiment) (See FIG. 12). The second item transferred to the upper side of the reprocessing case 216 drops around the reprocessing copper 161 in the counterclockwise direction of FIG. 12, The second item returned to the inner side of the vicinity of the guide plate 241 is not returned to the upper conveying port 222 but hits the lower surface of the guide plate 241 and is guided to the lower side of the reprocessing case 216. Even if the second item passes through the position of the guide plate 241, the presence of the shielding plate 242 in the upper conveyance port 222 is reduced by the second water reducing chamber 58 (U-shaped cover 222) Lt; / RTI > Therefore, the presence of the guide plate 241 and the shielding plate 242 mutually complement each other, so that the second article discharged from the reducing cylinder 58 (U-shaped cover 222) toward the reprocessing case 216 It can smoothly and properly fall down from the upper side to the lower side of the reprocessing case 216 without being returned to the reducing cylinder 58 side.
As shown in Figs. 6 to 12, the reprocessing copper 161 for reprocessing (re-throttling) the secondary product has a longitudinal reprocessing shaft 217 extending in parallel with the reducing shaft 212 Respectively. The lower end of the reprocessing shaft 217 is rotatably supported on the bottom plate of the reprocessing case 216. [ The upper end side of the reprocessing shaft 217 is rotatably supported on a portion of the case body 231 of the drive case 230 on the side of the reprocessing case 216 side. At least the upper portion of the reprocessing shaft 217 is provided with a scraper plate 224 for preventing the second piece (such as straw scraper) from wrapping around the reprocessing shaft 217. The scraper plate 224 of the embodiment extends from the upper inner surface to the lower inner surface of the reprocessing case 216 and is inspected to rotate integrally with the reprocessing shaft 217. 12, the length R in the radial direction of the scraper plate 224 (the length from the center of the reprocessing shaft 217 to the side end outside the radius of the scraper plate 224) Is set to about half of the radius of the processing case 216 as viewed in a plane.
With the above arrangement, when the second item is transferred to the side of the reprocessing case 216 through the upper transfer port 222, the outer circumferences of the peripheral walls 216a, 220a of the upper transfer port 222 and the scraper plate 224 It is possible to surely prevent the rotation of the scraper plate 224 from interfering with the succession of the second water because the second item is guided and inserted toward the gap between the side end portions. Therefore, the second item in the reprocessing case 216 can be succeeded very smoothly. It is also possible to suppress the winding and de-embedding of straw debris from the relationship between the presence of the scraper plate 224 and the guide / feed direction of the second water to the upper portion of the reprocessing copper 161 (upper portion of the reprocessing shaft 217).
A plurality of second processing teeth 225 which stir the second material inherited from the reduction conveyor 160 and a plurality of second processing teeth 225 which are formed of a spiral formed in the form of a spiral are formed in the scraper plate 224 on the reprocessing shaft 217, (Two in the embodiment) discharging / discharging the second item from the lower conveying port 223 of the reprocessing case 216 communicating with the inlet 215a of the second burning unit 215, And a blade 226. A conveying body 243 is provided at a position of the scraper plate 224 that is opposed to the upper conveying port 222. A plurality of No. 2 processing teeth 225 are radially arranged at a position lower than the upper conveying port 222 of the scraper plate 224. [ On the inner surface side of the reprocessing case 216, receiving teeth 227 are attached so as to pass between two sets of the second processing teeth 225. That is, in the reprocessing case 216, a scraper plate 224, a pair of conveying augers 243, a plurality of No. 2 processing teeth 225, a plurality of receiving teeth 227 and two discharge blades 226 are accommodated.
In the embodiment shown in Figs. 9 to 11, the group of the No. 2 processing teeth 225 and the receiving teeth 227 are positioned between the two transfer ports 222, 223 in the reprocessing case 216. Two discharge blades 226 are placed on the lower conveying port 223 of the reprocessing case 216. The upper and lower lengths Lu and Ld of the upper transfer port 222 and the lower transfer port 223 and the vertical length Lc between the transfer ports 222 and 223 are substantially the same (Lu? Ld? Lc). Each receiving tooth 227 is integrally provided in the reprocessing case 216 so as to protrude to the outer surface side of the reprocessing case 216 and forms a strength member of the reprocessing case 216.
The second item transferred into the reprocessing case 216 through the upper conveying port 222 by the scraping blade 214 of the reduction conveyor 160 drops down from the upper side of the reprocessing case 216 (Such as peeling of the clogged grain or rubbing of straw crumbs) by the teeth 97 and the receiving teeth 100. The processed second item transferred to the lower side of the reprocessing case 216 is discharged from the lower delivery port 223 toward the inclined inner surface of the second burning port 215 by the discharge blade 98.
As shown in Figs. 8 to 11, a driving case 230 is attached to the upper end side of the reducing cylinder 58 (U-shaped cover 220) and the upper opening side of the reprocessing case 216. [ The drive case 230 includes a plate-shaped case body 231 and a case lid 232 detachably covering the case body. A pulley / belt transmission mechanism 233 for transmitting the rotational power of the reduction conveyor 160 to the reprocessing copper 161 is disposed on the case main body 231.
In the embodiment, the drive pulley 234 is fixed to the projecting end of the transfer ending side of the reduction shaft 212 supported on the case body 231. Similarly, a driven pulley 235 is fixed to the protruding end of the transporting end side of the reprocessing shaft 217 supported on the case body 231. An endless belt 236 is wound around these two spur gears 234 and 235. The endless belt 236 is configured to adjust tension by means of a tension roller 237. The operation of the pulley / belt transmission mechanism 233 causes the reprocessing copper 161 to rotate counterclockwise around the reprocessing shaft 217 in FIG. 12 ) In the direction of rotation). The case lid 232 is bolted to the case body 231 while covering the pulley / belt transmission mechanism 233 from above. When the bolt is loosened and the case lid 232 is removed, the pulley / belt transmission mechanism 233 is exposed on the case body 231. The power transmission mechanism from the reduction conveyor 160 to the reprocessing copper 161 is not limited to the pulley-to-belt transmission mechanism 233 described above, and may be a sprocket-type or gear-type.
According to the above-described structure, when the uncut portion of the package is cut by the cutting device 3 and the cutaway portion supplied from the cutting device 3 is tramped by the trolling device 5, The grain is selected by the oscillating screening unit 52. The sizing as the first item selected by the oscillating screening unit 52 is collected in the grain tank 7 by the No. 1 conveyor 55. When the mixture of the curled grains and straw crumbs as the second item selected by the oscillating screening unit 52 drops onto the second conveyor 56, the second item is conveyed from the second conveyor 56 to the reduction conveyor 160 And transferred from the reduction conveyor 160 into the reprocessing case 216. [
The second item introduced into the interior of the reprocessing case 216 from the conveying end side (upper end side) of the reduction conveyor 160 by the scraping blade 214 passes through the No. 2 processing tooth 225 and the receiving tooth 227 And then discharged to the upper surface of the feed pan 183 from the second burning section 215 by the discharge blade 226 to be transferred to the swinging discriminating section 52 (the process of separating the stuck grains, ). ≪ / RTI > Therefore, the curved grains remaining in the No. 2 conveyor fall down to the No. 1 conveyor (55) and are then carried into the grain tank (7). The straw scraps in the second pot are discharged to the outside of the apparatus from the suction discharge port 189 or the swing discharge port 190 of the discharge fan 61 via the upper surface of the chaff sheave 184.
In addition, the No. 2 conveyor 56, the reduction conveyor 160, and the reprocessing copper 161 always rotate in conjunction with each other, but the number of revolutions is different. In the embodiment, the reduction conveyor 160 is rotated at a higher speed than the second conveyor 56, and the reworked copper 161 is rotated at a higher speed than the reduction conveyor 160. That is, the amount of conveyance per unit time of the reduction conveyor 160 is made larger than the conveyance amount per unit time of the No. 2 conveyor 56, and the amount of conveyance per unit time of the reprocessing copper 161 Thereby preventing the second item from being clogged during the conveyance in the reduction conveyor 160 or the reprocessing copper 161. [
(6). Drive structure of the oscillating screening panel
Next, the drive structure of the oscillation screening unit 52 will be described with reference to Figs. 13 (a) and 13 (b). As shown in Fig. 13 (a), a pair of left and right support bosses 251 are bolted to the lower surface side of the rear part of the swinging and sorting plate 52 in a downwardly protruding posture. A guide roller 253 is rotatably mounted on one end side (left and right outside) of the roller shaft 252 in the transverse direction inserted and fixed to the boss portion of each support boss body 251. The left and right guide rollers 253 are supported so as to be capable of rolling on the rear guide rails 182 corresponding thereto. The other end side (right and left inner side) of each roller shaft 252 is rotatably supported on one end side in the front-rear direction of the swing link 254 through a bearing member (not shown). A longitudinally intermediate portion (reciprocating shaft portion 162y described later) of the swing shaft 162 is rotatably supported on the other end side of the swing link 254 in the front-rear direction through a bearing member 255. [
The pivot shaft 162 is for converting the rotational motion of the pivot shaft 162 into the reciprocating motion of the pivot discriminating board 52 and is mounted over the left and right side walls 180a and 180b of the thruster housing 180 . The pivot shaft 162 of the embodiment includes a first rotating shaft portion 162x supported by the left side wall 180b of the thresher housing 180 and a second rotating shaft portion 162x supported by the right side wall 180a of the thresher housing 180. [ And a reciprocating shaft portion 162y connecting the both rotary shafts. As shown in Fig. 13, the axis centers (rotation centers) of the two rotary shafts 162x and 162z are positioned on the same axis. The axial center of the reciprocating shaft portion 162y is extended in a substantially parallel state in an eccentric state with respect to the axial center (rotation center) of the both rotary shafts 162x and 162z. A rotation power from the airflow fan shaft 156 is transmitted to the protruding end side (the support shaft portion 162x1 described later) protruding outward from the thresher housing 180 at the first rotary shaft portion 162x via the electric belt 257 A drive input pulley 256 is fixed.
Each of the rotary shaft portions 162x 162z is constituted by a shaft portion 162x1 162z1 serving as a center of rotation and a boss portion 162x2 162z2 integrally formed thereon. The left and right end sides of the reciprocating shaft portion 162y are inserted into the respective boss portions 162x2 (162z2). The boss portion 162x2 of the first rotating shaft portion 162x and the distal end side of the reciprocating shaft portion 162y are detachably connected by a key 258 and a pin 259. [ A slit 260 (notch groove) communicating with the boss hole of the boss portion is formed in the boss portion 162z2 of the second rotary shaft portion 162z. The second rotary shaft portion 162z and the reciprocating shaft portion 162y are connected so as not to be pulled out by the welding using the slit 260 in a state where the distal end side of the reciprocating shaft portion 162y is inserted into the boss portion 162z2 (a) and Fig. 13 (b), respectively. Therefore, the pivot shaft 162 of the embodiment is configured to be separable into two members by the set of the first rotary shaft portion 162x, the reciprocating shaft portion 162y, and the second rotary shaft 162z, 162 are easily separated from each other. In this case, there is an advantage that the maintenance work such as replacement of the bearing member 255 that axially supports the pivot shaft 162 is easy.
When the both rotary shafts 162x and 162z are coaxially rotated by the rotational power transmitted from the torsion fan shafts 156 via the drive input pulley 256, the reciprocating shaft portion 162y rotates about the axis of the rotary shafts 162x and 162z . The circular motion of the reciprocating shaft portion 162y is converted into a reciprocating motion along the rear guide rails 182 of both support bosses 251 via both swing links 254. As a result, the oscillation screening unit 52 reciprocates (oscillates) obliquely downward from the front or obliquely upward and backward.
(7). theorem
As clearly shown in the above description of the substrate and Figs. 10 to 12, the graining devices 57 and 159 for conveying the first item after the threshing selection to the grain tank 7 and the second item after the threshing- (58, 160) for returning the second item to the conveying end side of the second reducing device (58, 160), and the second conveying device (57, 159) and the second reducing device (58, 160) between the toning device (5) and the grain tank (7) And the first and second reducing devices 58 and 160 are arranged in the longitudinal direction in the forward and rearward directions in the order of the toners 57 and 159 and the second reducing devices 58 and 160, 5, the reprocessing device 59 is positioned so as to overlap the area of the feed room 173 of the grain device 17, It is possible to reduce the space occupied in the left and right width directions of the first and second reduction devices 57 and 159 and the second reducing device 58 and 160 and the reprocessing device 59, It is possible to arrange the gravity devices 57 and 159, the second reducing devices 58 and 160 and the reprocessing device 59 in a compact manner. Therefore, it is possible to enlarge the space occupied in the left and right width directions of the trolley unit 5 and the grain tank 7 without increasing the left and right width directions of the combine. Thus, without increasing the size of the combine, Can be achieved.
As described above, when the sidewalls are viewed between the gravity devices 57, 159 and the second reducing devices 58, 160, the re-process is performed so as to overlap the area of the supply chamber 173 of the threshing device 5, It is possible to smoothly return the second item subjected to the reprocessing (re-throttling) to the feed chamber 173 of the threshing device 5 without scattering it. Accordingly, it is possible to secure a sufficient distance for moving the processed second articles while being sorted in the threshing device 5, and it is possible to contribute to the improvement of the sorting ability of the combine.
6 and 10 and 11, the rotation axis 212 of the reduction conveyor 160 in the reduction apparatuses 58 and 160 and the rotation axis 212 of the reduction conveyor 160 The length of the reprocessing copper 161 in the direction of the rotating shaft 217 can be made long along the reduction conveyor 160 because the rotation axis 217 of the reprocessing copper 161 having the reprocessing copper 161 extends in parallel It becomes. Therefore, it is possible to secure a sufficient distance for the second article to move within the reprocessing apparatus 59 for re-processing (re-treading), thereby improving the reprocessing function of the second water by the reprocessing copper 161 It has an effect that it can be devised.
10 and 12, the lower part of the reprocessing device 59 communicates with the threshing device 5 through a second burning part 215, and the threshing device (not shown) Since the discharge port 215b of the second burning port 215 is opened in front of the support frame 218 for supporting the crimp net 60 on one side wall of the second burning port 215 From the discharge port 215b of the threshing device 5 toward the front side of the threshing device 5 (the front side of the swinging and sorting tray 52), the processed second article can smoothly be guided and discharged without being scattered have. Therefore, it is possible to suppress the possibility that the processed second article is locally deposited, for example, in the vicinity of the second burner 215, and further contributes to the improvement of the sorting ability of the combine .
As clearly shown in the above-described substrate and Figs. 6 to 11, the second item is subjected to reprocessing at the conveying end side of the second reducing apparatuses 58 and 160 for returning the second item after the threshing and sorting to the threshing apparatus 5 The lower portion of the reprocessing device 59 is connected to the second burning discharge port 59 located below the rotary shaft 158 of the ram 51 in the threshing device 5, And the bottom of the reprocessing device 59 is connected to the rear part of the rear part of the second burning part 215. Thus, It is possible to transfer the second item from the position lower than the rotation axis 158 of the ram 51 to the threshing device 5 by making it difficult for the second item to collide with the ram 51 or the crimp net 60 or the like. It is possible to suppress the debris and the disintegration of the water No. 2 which has been treated by the collision with the above-mentioned elevation (51) or the like.
As clearly shown in the above-described substrate and Figs. 10 to 12, gravity devices 57 and 159 for conveying the first item after the threshing selection to the grain tank 7 are disposed in the longitudinally extending position, And the outer shape of the second burning unit 215 is formed in a funnel shape that diverges forward downward, so that the two burning units 215 are arranged in the forward and downward directions, And the two-piece discharging portion 215 is arranged so as to partially overlap with the middle portion of the balancing device 57, 159 when seen from the side. Therefore, the width of the second discharging portion 215 is narrower toward the front The second burning-out portion 215 to be formed is extended forward by using the clearance space between the threshing device 5 and the kiln devices 57 and 159. Therefore, it is possible to disperse the processed second material in the threshing device 5 widely and discharge it. The second burning unit 215 is inclined to approach the threshing unit 5 as it goes downward. Therefore, the second burning unit 215 is smoothly processed from the lower part of the reprocessing unit 59 through the second burning unit 215 There is also an advantage that it is possible to guide dropping of the second item which is finished.
The front end side of the discharge port 215b of the second burning port 215 as viewed from the side is connected to the front end of the threshing device 5 (see FIG. 6, FIG. 7 and FIG. 10 to FIG. 12) Since the rear end side of the discharge port 215b is located on the chaff sheave 184 of the threshing device 5, The discharge port 215b is widely opened at one side wall 180a of the threshing device 5 and the discharge port 215b of the second discharge port 215 is processed toward the feed fan 183 It is possible to efficiently guide and discharge the finished second item. Therefore, it is possible to sufficiently secure the moving distance of the processed second articles while being sorted in the threshing device 5, and it is possible to improve the sorting performance of the combine.
As clearly shown in the above-described substrate and Figs. 9 to 11, the second item is subjected to reprocessing at the conveying end side of the second reducing apparatuses 58 and 160 for returning the second item after the threshing selection to the threshing apparatus 5 Wherein the re-treating device (59) is provided with an upper conveying port (222) communicating with the second reducing device (58, 160) and a second conveying device And a plurality of receiving teeth 227 are provided between the upper conveying port 222 and the lower conveying port 223 on the inner surface side of the reprocessing device 59 On the other hand, the reprocessing copper 161 provided in the reprocessing apparatus 59 is provided with the processing teeth 225 located between the respective receiving teeth 227. In the reprocessing apparatus 59, So that the burr moves from the upper conveying port 222 toward the lower conveying port 223 Control because, the second beonmul succession from the two-time reduction device (58, 160) is able to fall by its own weight the inside of the material processing device (59). Therefore, the function of conveying the second water is not required, since only the functions of disengaging the clogged grain and loosening the rice straw bundle are provided in the respective processing teeth 225 and the respective receiving teeth 227. Therefore, the processing teeth 225 and the respective receiving teeth 227 can be formed in a simple structure without deteriorating the reprocessing ability (retreating ability).
10, the upper and lower lengths Lu and Ld of the upper transfer port 222 and the lower transfer port 223 and the lengths Ld and Ld of the two transfer ports 222, 223 are set to substantially the same dimension (Lu? Ld? Lc), the reprocessing apparatus 59 is almost divided into three halves, and the reprocessing apparatus 59 performs reprocessing It is possible to reduce the possibility that the respective processing teeth 225 and the respective receiving teeth 227 remain in the reprocessing device 59 for a long period of time while maintaining the capability of re-treading. Therefore, the clogging in the reprocessing device 59 can be suppressed, and the processed second processed product can be smoothly returned to the threshing device 5 side.
8 to 11, each of the receiving teeth 227 protrudes to the outer surface side of the reprocessing device 59, and the strength members of the reprocessing device 59 So that each of the receiving teeth 227 itself also serves as a reinforcing member for the reprocessing device 59. Therefore, it is possible to improve the rigidity of the reprocessing apparatus 59 (reprocessing case 216).
As clearly shown in the above-described substrate and Figs. 10 to 12, the second item is subjected to reprocessing at the conveying end side of the second reducing apparatuses 58 and 160 for returning the second item after the threshing and sorting to the threshing apparatus 5 (59) in the re-treating device (59), and a re-treating device (59) for re-treating the re-treated copper in the re-treating device (59) The rotation shaft 217 of the second conveying device 161 extends in parallel to the second conveying device 222 and the second conveying device 222 is connected to the second conveying device 58, The portions 216a and 220a along the second water flow direction from the apparatuses 58 and 160 to the reprocessing apparatus 59 are connected to the inner circumferences of the second reducing apparatuses 58 and 160 and the reprocessing apparatus 59 The second conveyed to the reduction conveyor 160 is conveyed along the common tangent line TL, The conveying force by the conveying end side of the reduction conveyor 160 is not reduced so much that the outer side of the radius of the reprocessing copper 161 along the portions 216a and 220a of the peripheral wall of the upper conveying passage 222 To the processing apparatus 59 side. Therefore, it is possible to smooth the succession of the second water from the second reducing apparatuses 58, 160 to the reprocessing apparatus 59, thereby preventing the stay at the time of succession and preventing the second reducing apparatuses 58, It is possible to suppress the clogging between the processing apparatus and the processing apparatus (59).
10 to 12, at least the upper portion of the rotating shaft 212 of the reprocessed copper 161 is provided with a waterproofing member (not shown) And a gap between the portions 216a and 220a along the common tangent line of the peripheral wall of the upper conveying passage 222 and the side ends outside the radius of the scraper plate 224 The rotation of the scraper plate 224 when the second item is transferred to the side of the reprocessing device 59 through the upper conveying passage 222 is the same as that of the succession of the second water It is possible to reliably avoid disturbance. Therefore, it is possible to transfer the second item in the reprocessing device 59 with very smooth movement. In addition, there is an advantage that it is possible to suppress winding and debris of the straw debris from the relationship between the presence of the scraper plate 224 and the guide / insertion direction of the second water to the upper portion of the reprocessing copper 161.
9-11, the scraper plate 224 extends from the upper inner surface to the lower inner surface of the reprocessor 59, and the upper end of the scraper plate 224, Since the plurality of processing teeth 225 are attached at a lower position than the upper conveying port 222, the presence of the scraper plate 224 prevents the winding and demolding of the straw debris to the entire reworked copper 161 It is possible to stably support each of the processing teeth 225 while suppressing the processing.
