  And each communication part 68G and 69F of the 1st sorting case 68 and the 2nd sorting case 69 functions as a collection part which collects the grain after sorting to the grain tank 8.

  The suction fan 71 operates by suction when the power from the engine 3 transmitted to the processing cylinder 64 is transmitted through a belt transmission type transmission mechanism 73 and driven by the power. The other end of the first duct 70 is connected to the suction port 71 a of the suction fan 71. As a result, the suction port 71 a of the suction fan 71 is communicated with the inside of the first sorting case 68 and the inside of the second sorting case 69 via the first duct 70. A second duct 72 is connected to the discharge port 71 b of the suction fan 71. The second duct 72 guides the discharge from the discharge port 71 b of the suction fan 71 toward the discharge port 67.

  From the above configuration, the first sorting case 68 is supplied with a processed product having a high content of single-grained grains that have been suitably threshed by the rotation drive of the handling cylinder 27 and leaked from the receiving net 28. The second sorting case 69 is supplied with a processed product whose grain has been promoted by re-threshing processing by the first re-threshing device 60 or the second re-threshing device 63.

  Then, due to the suction action of the suction fan 71, outside air is introduced into the first sorting case 68 from the intake port 68a of the cylindrical portion 68B and the intake holes 68b of the outside air introduction portion 68D. In the first sorting case 68, the outside air from the intake port 68a becomes a swirling flow that rises toward the first duct 70 while swirling along the inner surface of the first sorting case 68, and each intake hole 68b. The outside air from the air passes through the central portion of the first sorting case 68 and rises in a straight line toward the first duct 70. For the second sorting case 69, outside air is introduced into the second sorting case 69 from the intake port 69a of the cylindrical portion 69B and the intake holes 69b of the outside air introducing portion 69D. Inside, the outside air from the intake port 69a becomes a swirl flow that rises toward the first duct 70 while swirling along the inner surface of the second sorting case 69, and the outside air from each intake hole 69b is second sorted. The upward flow rises linearly through the center of the case 69 toward the first duct 70.

  That is, due to the suction action of the suction fan 71, the inner surfaces of the respective sorting cases 68 and 69 are directed from the lower part thereof toward the upper first duct 70 inside the first sorting case 68 and the second sorting case 69. A whirlwind that blows along the sway is generated.

  Thereby, in the 1st selection case 68, the processed material with much content of the single grain from the threshing apparatus 6 is made into the tangent with respect to the cylindrical part 68B by the 1st guide duct 68E and the 2nd guide duct 68F. The grains having a large specific gravity are directed toward the inner surface side of the first sorting case 68 by the centrifugal action of the swirling flow generated in the first sorting case 68 along the inside. When the sawdust is directed toward the center of the first sorting case 68, it is sorted into grains having a large specific gravity and sawdust having a low specific gravity. And the grain with a large specific gravity flows down along the inner surface of the first sorting case 68 by its own weight without receiving the action of the upward flow passing through the center of the sorting case 259. On the other hand, sawdust having a low specific gravity rides on the upward flow and blows up through the center of the first sorting case 68 and passes through the first duct 70, the suction fan 71, and the second duct 72 to the discharge port 67. Guided.

  In the second sorting case 69, the processed product in which the unigraining of the grains from the first rethreshing device 60 and the second rethreshing device 63 is promoted is guided along the tangent to the cylindrical portion 69B by the guide duct 69E. Due to the centrifugal action of the swirling flow generated inside the second sorting case 69, the grains having a large specific gravity are directed toward the inner surface of the second sorting case 69, and the shavings having a small specific gravity are used. By moving toward the center side of the second sorting case 68, the grains are sorted into grains with a large specific gravity and sawdust with a small specific gravity. The grain having a large specific gravity flows down along the inner surface of the second sorting case 69 by its own weight without receiving the action of the upward flow passing through the center of the sorting case 259. On the other hand, sawdust having a low specific gravity rides on the upward flow and blows up through the center of the second sorting case 69, passes through the first duct 70, the suction fan 71, and the second duct 72 to the discharge port 67. Guided.

  In other words, the first sorting case 68 is a sorting unit that performs wind sorting processing by wind on the processed product from the threshing device 6, and the second sorting case 69 is from the first rethreshing device 60 and the second rethreshing device 63. This sorter performs a wind power sorting process by a whirlwind, and by the wind wind sorting process by the whirlwind in each of the sorting sections 68 and 69, a grain having a large specific gravity can be accurately sorted and allowed to flow down.

  Then, the second transport mechanism 245 transports the processed material leaked from the latter half of the receiving network 228 and the processed material flowing down from the dust sending port 242 toward the cyclone sorting device 207, thereby causing the latter half of the receiving network 228 to move. Compared with a case where a dedicated transport mechanism for the processed material leaked from the section and a dedicated transport mechanism for the processed material flowing down from the dust feed port 242 are provided, the structure and cost of the transport device 243 is simplified. Can be reduced.

  In addition, since the conveying device 243 does not protrude from the threshing device 206 to the rear side of the vehicle body, the overall length of the vehicle body can be shortened. Transport can be facilitated.

  As shown in FIGS. 10 to 15, the cyclone sorting device 207 is configured by arranging a sorting case 259, a dust exhaust duct 260, a suction fan 261 as an exhaust fan, and the like in the right rear half of the body frame 201. Yes.

The second communication port 259b is formed so as to open toward the left front side of the vehicle body on the upper side of the first cylindrical portion 259B. The third communication port 259c is formed so as to open toward the right rear of the vehicle body at the upper end portion of the first cylindrical portion 259B above the second communication port 259b.

  The first communication port 259a is connected to the lower side of the first cylindrical portion 259B and the discharge port 250a formed at the upper end portion of the first transporting conveyor 250, which is the transfer terminal portion of the first transfer mechanism 244. A first communication duct 262 as a first communication part is provided. On the upper side of the first cylindrical portion 259B, the second communication port 259b and the discharge port 255a formed at the upper end portion of the second transporting conveyor 255 serving as the transfer terminal portion of the second transfer mechanism 245 are connected in communication. A second communication duct 263 as a second communication part is provided. One end portion of the dust discharge duct 260 is connected to the upper end portion of the first cylindrical portion 259B using the third communication port 259c.

  The first communication duct 262 is formed so as to guide the processed product conveyed by the first conveying conveyor 250 to the first communication port 259a of the first cylindrical portion 259B along a tangent to the first cylindrical portion 259B. Has been. The second communication duct 263 is formed so as to guide the processed product conveyed by the second conveying conveyor 255 to the second communication port 259b of the first cylindrical portion 259B along a tangent to the first cylindrical portion 259B. Has been. The dust discharge duct 260 guides the waste sorted inside the sorting case 259 to flow out from the third communication port 259c of the first cylindrical portion 259B along a tangent to the first cylindrical portion 259B, and It forms so that it may guide toward the suction inlet 261a of the suction fan 261 after outflow.

  The first communication duct 262 is formed with a first intake port 262a for primary intake that enables the introduction of outside air into the sorting case 259. The second communication duct 263 is formed with a second intake port 263a having an opening area smaller than that of the first intake port 262a for primary intake that enables introduction of outside air into the sorting case 259. A plurality of second cylindrical portions 259D and second conical portions 259E are formed so that a slit-shaped gap 259G is formed between them for secondary intake that allows introduction of outside air into the sorting case 259. Bolts are connected via spacers 259H. The second conical portion 259E is formed with a large number of intake holes 259d for tertiary intake that allows the introduction of outside air into the sorting case 259.

  The third cylindrical portion 259F is formed so that the inside of the sorting case 259 communicates with the inside of the grain tank 208. Thereby, the 3rd cylindrical part 259F functions as a collection part which collects the grain after sorting to grain tank 8.

  The suction fan 261 operates by suction when the power from the engine 203 transmitted to the feed chain 233 is transmitted through the power distribution mechanism 237 and the like and is driven by the power. The other end of the dust exhaust duct 260 is connected to the suction port 261 a of the suction fan 261. As a result, the suction port 261 a of the suction fan 261 is communicated with the inside of the sorting case 259 through the dust discharge duct 260.

  The suction fan 261 is arranged and set so that the discharge port 261b is located at the rear end of the vehicle body, and is oriented so that the discharge from the discharge port 261b is discharged toward the rear of the vehicle body.

  From the above configuration, a processed product having a high content of single-grained grains that have been threshed appropriately by the rotational drive of the barrel 227 and leaked from the first half of the receiving net 228 is supplied to the lower portion of the sorting case 259. Is done. The upper part of the sorting case 259 leaks or flows down from the latter half of the receiving net 228 or the dust feed port 242 without leaking from the first half of the receiving net 228, and the grain is rethreshed by the rethreshing device 254. A processed product with a high content of sawdust is promoted.

  Then, due to the suction action of the suction fan 261, the outside air flows into the first intake port 262a of the first communication duct 262, the second intake port 263a of the second communication duct 263, the gap 259G of the sorting case 259, and each intake hole 259d. Are introduced into the sorting case 259, and outside air from the first intake port 262 a and outside air from the second intake port 263 a are exhausted while turning along the inner surface of the sorting case 259. Ascending flow that rises toward the dust duct 260, and the upward air from which the outside air from the gap 259 </ b> G and the outside air from each intake hole 259 d rise linearly toward the dust duct 260 through the center of the sorting case 259. It becomes.

  In other words, due to the suction action of the suction fan 261, whirling is generated in the sorting case 259 while turning along the inner surface of the sorting case 259 from the lower part toward the upper dust discharge duct 260.

  Thereby, in the lower part of the sorting case 259, the processed product with a large content of single grains from the threshing device 206 is sorted along the tangent to the first cylindrical portion 259B by the first communication duct 262. 259 is guided to be supplied to the inside of the 259, and by the centrifugal action of the swirling flow generated in the inside, the grains having a large specific gravity are directed to the inner surface side of the sorting case 259, and the sawdust having a small specific gravity is fed to the sorting case 259. By going to the center side, it is sorted into grains with high specific gravity and sawdust with low specific gravity. And the grain with large specific gravity flows down along the inner surface of the sorting case 259 by its own weight without receiving the action of the upward flow passing through the center of the sorting case 259. On the other hand, the sawdust having a low specific gravity rides on the upward flow and blows up through the center portion of the sorting case 259, and then follows the tangent line from the third communication port 259c of the first cylindrical portion 259B to the first cylindrical portion 259B. Then, the air is guided by the dust discharge duct 260 and discharged from the discharge port 261b of the suction fan 261 toward the rear of the vehicle body via the dust discharge duct 260 and the suction fan 261.

  In the upper part of the sorting case 259, the processed material having a high content of sawdust from the threshing device 206 is supplied to the inside of the sorting case 259 along the tangent to the first cylindrical portion 259B by the second communication duct 263. As a result of the centrifugal action of the swirling flow generated in the interior, the grains having a large specific gravity are directed to the inner surface side of the sorting case 259 and the shavings having a small specific gravity are directed to the center side of the sorting case 259. , Sorted into grains with high specific gravity and sawdust with low specific gravity. And the grain with large specific gravity flows down along the inner surface of the sorting case 259 by its own weight without receiving the action of the upward flow passing through the center of the sorting case 259. On the other hand, the sawdust having a low specific gravity rides on the upward flow and blows up through the center portion of the sorting case 259, and then follows the tangent line from the third communication port 259c of the first cylindrical portion 259B to the first cylindrical portion 259B. Then, the air is guided by the dust discharge duct 260 and discharged from the discharge port 261b of the suction fan 261 toward the rear of the vehicle body via the dust discharge duct 260 and the suction fan 261.

  In other words, the sorting case 259 is a sorting unit that performs wind-power sorting processing by whirlwind on the processed product from the threshing device 206, and the grain that has been made into a single grain in the sorting region on the lower side near the grain tank 208 in the sorting unit 259 By supplying a processed product having a large grain content, a large number of grains having a large specific gravity can be quickly dropped by themselves toward the inside of the grain tank 208. In addition, by supplying a processed material having a high content of sawdust to the upper sorting area near the dust duct 260 in the sorting unit 259, a large amount of sawdust having a small specific gravity is supplied to the dust duct 260. It can be quickly raised and discharged from the discharge port 261b of the suction fan 261 toward the rear of the vehicle body via the dust discharge duct 260.

  In addition, the configuration in which a single sorting unit 259 is connected to the suction fan 261 simplifies the configuration, reduces costs, and saves space compared to the case where a plurality of sorting units 259 are connected. The pressure loss in the cyclone sorting device 207 can be suppressed while achieving the reduction of the pressure.

  As a result, simplification of configuration, cost reduction, and reduction in the size of the vehicle body due to space saving of the cyclone sorting device 207, and the like, aiming to improve the sorting accuracy in the sorting unit 259 and improve the grain recovery efficiency. be able to.

  The suction fan 71 is preferably a plate fan. Although not shown, a decorative cover that covers the cyclone sorting device 207 is detachably attached to the right rear half of the body frame 201.

  As shown in FIGS. 14 to 20, in the first cylindrical portion 259 </ b> B, the second communication port 259 b is located at a position farther from the third communication port 259 c toward the upper side in the swirling direction of the workpiece than the first communication port 259 a. The layout is set as follows. As a result, it becomes easy to perform the wind sorting process by the whirlwind on the processed material from the second communication port 259b close to the dust exhaust duct 260, and as a result, the selection accuracy for the processed material from the second communication port 259b can be improved. it can.

  As shown in FIGS. 13 to 18, the processed material having a large content of single grains from the first transport mechanism 244 is diffused inside the sorting case 259 on the inner surface on the lower side of the first cylindrical portion 259 </ b> B. A first diffusion member 264 is provided. The first diffusing member 264 has a length of about ½ of the circumferential length of the first cylindrical portion 259B from the upper part of the right edge of the first communication port 259a toward the lower side in the swiveling direction of the processing object. From the upper and lower intermediate portions of the right edge of the long rib-shaped upper guide plate 264A extending along the inner surface of the cylindrical portion 259B and the first communication port 259a toward the lower side in the swiveling direction of the processed material, the first cylindrical portion From the lower portion of the right edge of the first communication port 259a and the medium rib-shaped medium guide plate 264B extending along the inner surface of the first cylindrical portion 259B, and having a length of about ¼ of the circumferential length of 259B. A short rib-shaped lower guide plate extending along the inner surface of the first cylindrical portion 259B and having a length of about 1/8 of the circumferential length of the first cylindrical portion 259B toward the lower side in the turning direction of the processed material H.264C.

  In other words, the first diffusion member 264 sorts a processed product with a high content of single-grained grains supplied from the first communication port 259a of the sorting case 259 close to the grain tank 208 to the inside of the sorting case 259. The case 259 can be appropriately diffused in the circumferential direction, and the appropriately diffused processed material can be appropriately subjected to wind power sorting processing by a whirlwind.

  As a result, the sorting case in which the processed material having a large content of single-grained grains is hard to be subjected to the wind sorting process by the whirlwind from the first communication port 259a of the sorting case 259 close to the grain tank 208. It is possible to prevent the waste from flowing into the grain tank 208 in a lump that is supplied into the interior of 259 and has a large amount of swarf between the single grains.

  As a result, it is possible to avoid a decrease in sorting accuracy due to the processed material from the first communication port 259a flowing down into the grain tank 208 in a solid state.

  Note that the number of guide plates constituting the first diffusion member 264, the extension length, the extension angle, the width dimension, and the like can be variously changed.

  As shown in FIGS. 13 to 17 and FIG. 19, the processed material having a high content of sawdust from the second transport mechanism 245 is diffused inside the sorting case 259 on the inner surface on the upper side of the first cylindrical portion 259 </ b> B. A second diffusing member 265 is provided. The second diffusing member 265 is disposed and set on the inner surface of the first cylindrical portion 259B in the vicinity of the second communication port 259b on the lower side in the swirling direction of the processing object and located on the lower side in the swirling direction of the processing object. The guide surface 265A is formed so as to be located closer to the center of the first cylindrical portion 259B and diffuse the processed material from the second communication port 259b toward the center of the sorting case 259. The guide surface 265A is formed to have a width that is larger in the vertical width than the vertical length of the second communication port 259b.

  In other words, the second diffusion member 265 causes the upward flow to flow from the second communication port 259b of the sorting case 259 close to the dust discharge duct 260 to the inside of the sorting case 259 with a high content of sawdust. It can be diffused moderately toward the center of the sorting case 259 that blows through, and an upward flow can be appropriately applied to the moderately diffused processed material.

  As a result, from the second communication port 259b of the sorting case 259 close to the dust discharge duct 260, the processed material having a large amount of sawdust is swung along the inner surface of the sorting case 259 that is not easily affected by the upward flow. It is possible to prevent the liquid from flowing down along the inner surface of the sorting case 259 without being affected by the upward flow.

  As a result, it is possible to avoid a reduction in sorting accuracy due to the processed material from the second communication port 259b flowing down toward the inside of the grain tank 208 along the inner surface of the sorting case 259.

  The extension length of the guide surface 265A in the second diffusion member 265, the amount of the guide surface 265A entering the center side of the first cylindrical portion 259B, the vertical width of the guide surface 265A, and the like can be variously changed.

Each guide piece 266A is formed in an arc shape extending from the inner surface side of the sorting case 259 toward the center side of the sorting case 259 while having a receding angle that tilts toward the lower side in the turning direction of the processed material. Yes.

  As a result, among the processed materials flowing down along the inner surface of the sorting case 259, the shavings having a small specific gravity are guided toward the center side of the sorting case 259 without hindering the flow of single grains having a large specific gravity. By this guiding action, the outside air introduced from each intake hole 259d of the second conical portion 259E can be more reliably acted on the sawdust having a small specific gravity, and the inner surface of the sorting case 259 can be applied. The sawdust having a small specific gravity contained in the processed material flowing down can be more suitably blown toward the dust discharge duct 260. As a result, the sorting accuracy in the sorting case 259 can be further improved.

  The number of guide pieces installed in the guide member, the shape of the guide pieces, and the like can be variously changed. For example, although not shown, each guide piece 266A is disposed from the inner surface side of the sorting case 259 to the processed material. You may form so that it may extend linearly toward the center side of the selection case 259, facing the turning direction lower side.

  Although not shown, a guide member 266 is provided on the upper portion of the second conical portion 259E to prevent the flow of single-grained grains having a large specific gravity while preventing the flow of sawdust having a small specific gravity. Instead of or may be equipped with the guide member 266.

The fall prevention member 267 has a length of about a half of the circumferential length of the first cylindrical portion 259B from the lower end of the right edge of the third communication port 259c toward the upper side in the swiveling direction of the processing object. It is formed in a long rib shape extending along the inner surface of the portion 259B.

  That is, the debris blown up to the third communication port 259c that communicates the sorting case 259 and the dust discharge duct 260 by the swirling flow or the upward flow is received by the fall prevention member 267 and guided toward the dust discharge duct 260. To come.

  As a result, dust such as sawdust contained in the processed product can be quickly discharged from the third communication port 259c of the sorting case 259 to the outside of the vehicle via the dust discharge duct 260 and the suction fan 261. As a result, the sorting efficiency in the sorting case 259 can be further improved.

  The number of the fall prevention members 267, the extension length, the extension angle, the width dimension, and the like can be variously changed.

The front-rear length of the grain tank 208 is set to a length extending from the front-rear intermediate part to the rear end part of the body frame 201. The left and right width of the grain tank 208 is set to be wide across the left and right ends of the vehicle body. The vertical length of the grain tank 208 is set to a short length such that the upper end of the grain tank 208 does not become higher than the base end portion 217A of the cutting frame 217 serving as a swinging fulcrum of the cutting conveyance device 205.

  That is, the grain tank 208 is disposed on the lower side of the vehicle body in a state of being formed in a flat rectangular shape covering substantially the entire rear half of the vehicle body. Thereby, the threshing device 206 provided in the left half of the body frame 201 is mounted on the upper left portion of the grain tank 208. The cyclone sorting device 207 provided in the right rear half part of the body frame 201 is mounted on the upper right part of the grain tank 208. Then, by mounting the cyclone sorting device 207 on the grain tank 208, the grain tank 208 is positioned below the third cylindrical portion 259F in the cyclone sorting device 7, and thus the cyclone sorting device 207 The sorting case 259 can be directly communicated with the grain tank 208, whereby the grain flowing down from the sorting case 259 flows into the grain tank 208 as it is.

  Thus, in this combine, the grain tank 208 formed in the shape of a flat rectangular body covering substantially the entire rear half of the vehicle body is disposed on the lower side of the vehicle body, and the threshing device 206 and the cyclone sorting device are disposed on the upper portion thereof.

Compared to the combine of the structure, the left and right balance of the vehicle body can be effectively improved at the start of work where the storage amount of the grain tank 208 is small.

  In addition, by effectively utilizing the entire area of the rear half of the vehicle body for the grain tank 208, the grain tank 208 is formed in a flat shape with its height kept as low as possible while sufficiently securing its capacity. As a result, although the threshing device 206 and the cyclone sorting device 207 are arranged on the upper part of the grain tank 208, the vehicle height and the center of gravity position of the vehicle body can be kept low.

  Moreover, since the grains stored in the grain tank 208 contribute to lowering the center of gravity of the vehicle body, the stability of the vehicle body increases as the amount of the grains stored in the grain tank 208 increases with the progress of work. Will be improved.

  Although illustration is omitted, the grain tank 208 is reinforced by a plurality of reinforcing members or the like so as to have high strength that enables the threshing device 206 and the cyclone sorting device 207 to be mounted. Thereby, the grain tank 208 can be used also as the strength member of the vehicle body frame 201. As a result, it is possible to simplify the configuration of the vehicle body frame 201 while ensuring high strength as the vehicle body frame 201.

  As shown in FIGS. 9 to 15, the grain carry-out device 209 includes a carry-out conveyor 268 made up of front and rear screws, a lower case 269, a screw conveyance type lifting conveyor 270, an upper case 271, and a screw conveyance type discharge.

The carry-out conveyor 268 is a grain carry-out formed in the front-rear direction at the bottom of the right end side of the grain tank 208 so that the carry-out conveyor 268 is positioned at the end of the grain tank 208 opposite to the position of the threshing device 206 in the front-rear orientation. Is provided in the guide groove 208A. Power from the engine 203 is transmitted to the carry-out conveyor 268 via a belt tension type discharge clutch 273, a left-right transmission shaft 274, a pair of bevel gears 276 provided in the transmission case 275, and the like. . The carry-out conveyor 268 is driven by the power from the engine 203 to carry the grains accumulated in the guide groove 208 </ b> A toward the feed conveyor 270 erected at the right rear end of the vehicle body. The lower case 269 allows the rear end portion of the guide groove 208 </ b> A in the grain tank 208 to communicate with the lower end portion of the lifting conveyor 270 while allowing the discharge conveyor 272 to turn. Inside the lower case 269, a pair of bevel gears 277 for interlocking the carry-out conveyor 268 and the lifting conveyor 270 are provided. The lifting conveyor 270 is linked to the carry-out conveyor 268 to lift the grains carried by the carry-out conveyor 268 toward the discharge conveyor 272. The upper case 271 allows the upper end portion of the lifting conveyor 270 to communicate with the proximal end portion of the discharge conveyor 272 while allowing the discharge conveyor 272 to swing up and down. In the upper case 271, a pair of bevel gears 278 that link the lifting conveyor 270 and the discharge conveyor 272 are provided. The discharge conveyor 272 swings up and down by the operation of the hydraulic cylinder 279, swivels together with the lifting conveyor 270 and the upper case 271 by the operation of the hydraulic motor 280, and is interlocked with the lifting conveyor 270 by the lifting conveyor 270. The transported grain is conveyed toward a discharge port 272A formed at the free end portion of the discharge conveyor 272, and discharged from the discharge port 272A to a desired discharge position set by undulation swinging operation or turning operation. To do.

  And in this combine, as above-mentioned, the right end part of the grain tank 208 used as the opposite side to the threshing apparatus 206 mounted in the upper left part of the grain tank 208 by the comparatively heavy carrying-out conveyor 268 is carried out.
