It is to be noted that the cutting input shaft 17 is actuated by a rotational force equal to or less than the torque set by the torque limiter 104 to prevent the cutting blade 32 and the like from being damaged.

  The counter gear case 99 is provided with a feed chain tuning mechanism 112 having a planetary gear type transmission structure that connects the feed chain drive shaft 103 to the selection input shaft 82. The rotational output of the sorting input shaft 82 is shifted in proportion to the rotational speed of the cutting transmission shaft 101 by the feed chain tuning mechanism 112 and transmitted to the feed chain drive shaft 103. That is, by operating the feed chain 6 via the feed chain tuning mechanism 112, the feed chain is secured while ensuring the minimum rotational speed (constant rotational speed from the low-speed constant rotational gear 109) necessary for conveying the cereal. The cereal conveyance speed of 6 can be changed in synchronization with the vehicle speed.

  Next, the conveyance speed control of the vertical conveyance chain 34 as the cereal conveyance means of this embodiment will be described. FIG. 7 is a functional block diagram of the conveyance speed control means of the vertical conveyance chain 34, and includes a work controller 282 such as a microcomputer having a ROM storing a control program and a RAM storing various data. As shown in FIG. 7, on the input side of the work controller 282 configured by a microcomputer, a work switch 273 that detects the driving of the threshing device 5 and the like, and the cereal of the culm pulling device 223 ) Or the culm sensor 287 for detecting the culm (harvested culm) of the culm transporting device 224, the vehicle speed sensor 285 for detecting the moving speed of the traveling machine body 1, and the mowing rotation for detecting the rotational speed of the mowing input shaft 17. Sensor 288, conveyance speed setting dial 262 that adjusts the output rotation speed of the vertical conveyance drive electric motor 92 (operation speed of the vertical conveyance chain 34) steplessly, and the minimum output rotation speed of the vertical conveyance drive electric motor 92 ( A low speed rotation setting device 266 as a minimum rotation number setting device for setting a minimum operation speed of the vertical conveyance chain 34, and a maximum output rotation number (vertical conveyance chain 34) of the electric motor 92 for vertical conveyance driving. A high-speed rotation setting device 267 as a maximum rotation number setting device for setting the maximum operation speed), a vertical conveyance rotation sensor 312 for detecting an output rotation number of the vertical conveyance driving electric motor 92, and an auxiliary conveyance driving electric motor 93. An auxiliary conveyance rotation sensor 313 that detects the output rotation speed is connected.

  As shown in FIG. 7, on the output side of the work controller 282, a vertical conveyance driver 302 for operating the vertical conveyance drive electric motor 92 and an auxiliary conveyance driver 303 for operating the auxiliary conveyance drive electric motor 93 are connected. Yes. An electric motor 92 for vertical conveyance driving and a vertical conveyance driver 302 are connected to a generator 89 driven by the engine 14, and the electric motor 92 for vertical conveyance driving is configured to be operable by using the generator 89 as a power source. Further, the auxiliary transport driving electric motor 93 and the auxiliary transport driver 303 are connected to the generator 89, and the auxiliary transport driving electric motor 93 is configured to be operable by using the generator 89 as a power source.

  That is, based on the detection result of the cutting rotation sensor 288 and the set value of the conveyance speed setting dial 262, the output rotation speeds of the vertical conveyance driving electric motor 92 and the auxiliary conveyance driving electric motor 93 are automatically controlled. While the output rotation speeds of the vertical transport driving electric motor 92 and the auxiliary transport driving electric motor 93 are automatically controlled, the operator manually operates the transport speed setting dial 262 so that the vertical transport driving electric motor 92 and the auxiliary transport driving electric motor are operated. By changing the output rotation speed of the motor 93, the conveyance speed of the vertical conveyance chain 34 and the conveyance speed of the auxiliary stock former conveyance chains 35 and 36 can be adjusted. The automatic control is performed between the minimum rotation speed set by the low speed rotation setting device 266 and the maximum rotation speed set by the high speed rotation setting device 267, and the vertical conveyance driving electric motor 92 and the auxiliary conveyance driving electric motor. The output rotation speeds of 93 are associated with each other and can be changed. Therefore, the output rotational speed of the vertical transport driving electric motor 92 and the output rotational speed of the auxiliary transport driving electric motor 93 are changed in synchronization.

  Further, as shown in FIG. 7, a culm length sensor 289 that detects the culm length of the culm supplied to the threshing device 5 through the vertical transport chain 34 and the auxiliary stock former transport chains 35 and 36 is input to the work controller 282. Connected to the side. A handling depth adjustment motor 94 that changes the posture of the vertical conveyance chain 34 is connected to the output side of the work controller 282. That is, at the grain culm inheriting portion between the feed end side of the vertical conveying chain 34 and the feed start end side of the feed chain 6, the handling depth adjusting motor 94 is rotated forward or reverse based on the detection result of the cocoon length sensor 289. Operates and moves the feed end side of the vertical conveying chain 34 by the handling depth adjusting motor 94 in the cocoon length direction of the cereal and maintains the length of the tip side of the culm inserted in the threshing device 5 at a constant level. Depth control is performed (see FIG. 4). With the handling depth control, the feed end side of the vertical conveyance chain 34 moves in the left-right direction, and enters and leaves the traveling machine body 1. The feed end side of the vertical conveying chain 34 protrudes toward the outside of the traveling machine body 1 when the culm is long and retreats toward the inside of the traveling machine 1 when the culm is short.

  In addition, the structure provided with the threshing device 5 which needs to be always driven at a constant rotational speed to maintain the threshing / sorting performance, in other words, the transmission structure in which the output of the constant rotational speed from the engine 14 is transmitted to the threshing device 5. Therefore, since the engine 14 is operated so as to maintain a substantially constant rotational speed at the maximum output state, the generator 89 can be driven at an optimal rotational speed by the output from the engine 14. That is, the proper output of the generator 89 necessary for the operation of the vertical transfer driving electric motor 92 and the auxiliary transfer driving electric motor 93 is reliably maintained, thereby cutting the stock of the cereal planted in the field. The electric motor 92 for longitudinal conveyance driving and the electric motor 93 for auxiliary conveyance driving can be operated at a suitable constant rotational speed.

  Next, FIG. 8 is a flowchart of the conveyance speed control. With reference to FIG. 8, the conveying operation | work of the harvested grain mash which operates the electric motor 92 for a vertical conveyance drive and the electric motor 93 for an auxiliary conveyance drive is demonstrated. When the work switch 273 is on (S1yes) and the grain sensor 287 is on (S2yes), the detected value of the vehicle speed sensor 285, the detected value of the cutting rotation sensor 288, and the set value of the conveyance speed setting dial 262 are Read (S3). The conveyance speed (vehicle speed synchronization speed) of the vertical conveyance chain 34 is calculated from the detection value of the vehicle speed sensor 285, the detection value of the cutting rotation sensor 288, and the setting value of the conveyance speed setting dial 262 (S4). Therefore, the operator can manually change the conveyance speed setting dial 262 to arbitrarily change the rotation speeds of the vertical conveyance drive electric motor 92 and the auxiliary conveyance drive electric motor 93. For example, even in a cutting operation under special conditions such as a cutting operation of cereals lying in the field, the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 (the rear tip transfer tine 38) are moved at a speed adapted to the cutting operation. Can operate.

  Further, during the harvesting operation for harvesting the cereals planted in the farm field, the rotational speed of the harvesting input shaft 17 detected by the harvesting rotation sensor 288 increases as the moving speed of the traveling machine body 1 is accelerated. In this case, the output rotation speed of the vertical conveyance driving electric motor 92 detected by the vertical conveyance rotation sensor 312 or the output rotation speed of the auxiliary conveyance driving electric motor 93 detected by the auxiliary conveyance rotation sensor 313 is determined by the cutting input shaft. It becomes relatively lower than the number of revolutions of 17, and the stock side of the grain straw transported by the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is delayed, and the tip side is in a transport posture leading. On the contrary, when the traveling speed of the traveling machine body 1 is reduced, the output rotational speed of the vertical transport driving electric motor 92 or the auxiliary transport driving electric motor 93 is relatively higher than the rotational speed of the cutting input shaft 17. When it becomes, it will be in the conveyance attitude | position which the stock side of the grain straw conveyed by the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36 precedes, and the tip side delays.

  The detection value of the vertical conveyance rotation sensor 312 (and auxiliary conveyance rotation sensor 313) is read (S5), the conveyance speed of the vertical conveyance chain 34 (and auxiliary conveyance chains 35 and 36) calculated in step 4 and the vertical conveyance rotation sensor. Whether the conveyance speed of the vertical conveyance chain 34 should be increased (S6) by comparing with the detected value (actual conveyance speed) of the 312 (auxiliary conveyance rotation sensor 313), or the conveyance speed of the vertical conveyance chain 34 is decelerated. Judgment is made (S11). When it is determined that the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 should be increased (S6yes), the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is increased. Speed control is executed (S7). As a result, the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is accelerated in proportion to the moving speed of the traveling machine 1, and the vertical transport chain 34 and the auxiliary transport chains 35 and 36 are operated at a speed synchronized with the vehicle speed. In addition, the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 does not become too slow compared with the moving speed of the traveling machine body 1, and the cereals transported by the vertical transport chain 34 and the auxiliary transport chains 35 and 36 Therefore, the stocker side is not delayed and the tip side is not preceded, so that clogging of the cereals in the middle of transportation or disturbance of the transportation posture of the cereals during transportation can be prevented, and the vertical transportation chain 34 and the auxiliary transportation chain 35 can be prevented. , 36 can be improved.

  When the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is increased by the speed increasing control (S7), the maximum operation of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 of the high-speed rotation setting device 267 is achieved. The speed set value is read (S8). It is determined that the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 are operating at high speed because the transfer speeds of the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 coincide with the maximum operating speed set value of the high-speed rotation setting device 267. When this is done (S9yes), constant rotation control of the vertical transfer chain 34 and the auxiliary transfer chains 35, 36 is executed (S10). Even if the traveling speed (vehicle speed) of the traveling machine body 1 is further increased, the vertical conveyance chain 34 is set to the set value of the high-speed rotation setting device 267 by the constant rotation control (S10) of the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36. In addition, the conveyance speed of the auxiliary conveyance chains 35 and 36 is maintained. That is, since the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36 are operated at a speed equal to or lower than the rotation speed set by the high-speed rotation setting device 267, the traveling speed (vehicle speed) of the traveling machine body 1 is increased. Even at an extremely high speed, the transport speed of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 does not become too high, and the vertical transport chain 34 (vertical transport driving electric motor 92) and the auxiliary transport chains 35 and 36 ( It is possible to prevent the auxiliary transport driving electric motor 93) from operating in an overloaded state, and to reduce disturbances in the transport posture of the cereal or damage to the vertical transport chain 34 and the auxiliary transport chains 35 and 36.

  On the other hand, during the harvesting operation for harvesting the cereals planted in the field, the rotational speed of the harvesting input shaft 17 detected by the harvesting rotation sensor 288 is reduced by reducing the moving speed of the traveling machine body 1. In this case, the output rotational speed of the vertical transport driving electric motor 92 (auxiliary transport driving electric motor 93) detected by the vertical transport rotation sensor 312 (auxiliary transport rotation sensor 313) is higher than the rotational speed of the cutting input shaft 17. Thus, the stock posture side of the grain straw transported by the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is preceded, and the tip side is delayed.

  The rotational speed of the cutting input shaft 17 is compared with the output rotational speed of the vertical transport driving electric motor 92 or the auxiliary transport driving electric motor 93, and the vertical transport driving electric motor 92 or the auxiliary transport driving electric motor 93 is decelerated. When it is determined that it is necessary to operate (S11yes), the vertical conveyance driver 302 is subjected to deceleration control, and deceleration control is performed to decelerate the conveyance speed of the vertical conveyance chain 34 or the auxiliary conveyance driving electric motor 93 ( S12). As a result, the decelerating control (S12) reduces the conveying speed of the vertical conveying chain 34 in proportion to the moving speed (vehicle speed) of the traveling machine body 1, and can operate the vertical conveying chain 34 at a speed synchronized with the vehicle speed. The conveying speed of the vertical conveying chain 34 or the auxiliary conveying chains 35, 36 does not become too fast compared to the moving speed of 1, and the posture of the cereals conveyed by the vertical conveying chain 34 or the auxiliary conveying chains 35, 36 is It is possible to prevent clogging of the cereals in the middle of transportation or disturbance of the transportation posture of the cereals during transportation, and the like, and the transportation of the vertical transportation chain 34 and the auxiliary transportation chains 35 and 36 without leading the head side and delaying the tip side. Performance can be improved.

  When the transport speeds of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 are decelerated by the above-described deceleration control (S12), the minimum operation speed setting of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 of the low-speed rotation setting device 266 is set. A value is read (S13). The vertical transport chain 34 and the auxiliary transport chains 35 and 36 operate at a low speed, and the transport speeds of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 coincide with the minimum operating speed set value of the low speed rotation setting device 266 to perform the vertical transport. When it is determined that the chain 34 and the auxiliary transport chains 35 and 36 are operating at a low speed (S14yes), constant rotation control (S10) of the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is executed. Therefore, even if the moving speed (vehicle speed) of the traveling machine body 1 is further reduced, the vertical conveyance chain is set to the set value of the low-speed rotation setting device 266 by the constant rotation control (S10) of the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36. 34 and the conveyance speed of the auxiliary conveyance chains 35 and 36 are maintained. That is, since the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 can be operated at a speed higher than the rotation speed set by the minimum rotation speed setting device 266, the traveling speed (vehicle speed) of the traveling machine body 1 is extremely low. However, the conveyance speed of the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36 can be prevented from becoming too slow, and clogging of the grains during conveyance can be prevented, and the conveyance performance of the vertical conveyance chain 34 and the auxiliary conveyance chains 35 and 36 can be prevented. Can be maintained.

  Furthermore, during the cutting operation in which the above-described acceleration control (S7), constant rotation control (S10), and deceleration control (S12) are performed, the traveling machine body 1 reaches the headland (bump) of the field and the field When the harvesting operation for cutting the grain culm planted in the plant ends and the grain culm sensor 287 is not turned on, in other words, a small amount of culm harvested last remains in the middle of the conveyance of the vertical conveying chain 34. Sometimes (S15yes), high-speed control for operating the vertical conveyance drive electric motor 92 and the auxiliary conveyance drive electric motor 93 at high speed is executed for an initial setting time (for example, about 10 seconds) (S16). The set value of the high-speed rotation setting device 267 is higher than the constant rotation control (S10) in which the transfer speed of the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 is maintained. Actuated.

  Therefore, at the end of cutting when the amount of cereals transported by the vertical transport chain 34 and the auxiliary transport chains 35 and 36 is reduced, the vertical transport chain 34 and the auxiliary transport chains 35 and 36 operate at high speeds. It is possible to properly maintain the grain haul conveying action of the chain 34 and the grain haul conveying action of the auxiliary conveying chains 35, 36, such as on the conveying terminal side (the grain haul inheriting part) of the vertical conveying chain 34 (or the auxiliary conveying chains 35, 36). It is possible to prevent spillage or clogging. In addition, during the initial setting time (for example, about 10 seconds) in which the high speed control (S16) is executed, the cereal residue remaining in the middle of the conveyance of the vertical conveyance chain 34 is conveyed to the conveyance end side of the auxiliary conveyance chains 35 and 36. Thus, the time required to be inherited by the feed chain 6 is desirable.

  As described above, when the high-speed control (S16) is executed and a certain time (for example, about 10 seconds) has elapsed (S17 yes), the handling depth adjustment motor 94 is set to the depth regardless of the detection result of the saddle length sensor 289. Actuating to the handling side, storage control for storing the vertical conveyance chain 34 inside the traveling machine body 1 is executed (S18). Therefore, when the cutting is finished, the vertical transfer chain 34 and the auxiliary transfer chains 35 and 36 operate at a high speed for a certain period of time, so that the vertical transfer chain 34 is automatically housed inside the traveling machine body 1 for the next stroke. It changes direction, moves between fields, or runs on the road. As a result, when the cutting is finished, the operator's operation for storing the vertical conveyance chain 34 becomes unnecessary. Further, it is possible to prevent the vertical transfer chain 34 from colliding with the bank or an obstacle around the bank.

  As described above, the vertical conveyance drive electric motor 92 that operates the vertical conveyance chain 34, the cutting rotation sensor 288 that detects the input rotation speed to the cutting blade device 222, and the rotation speed of the vertical conveyance drive electric motor 92. And a conveyance speed setting dial 262 capable of changing the speed, and the operator manually operates the conveyance speed setting dial 262 while controlling the number of rotations of the electric motor 92 for vertical conveyance drive based on the detection result of the cutting rotation sensor 288. Since the output rotation speed of the driving electric motor 92 is changed to adjust the conveying speed of the vertical conveying chain 34, the vertical conveying chain 34 is adjusted at a speed suitable for the characteristics of the cereal planted in the field. And the conveyance performance of the vertical conveyance chain 34 can be improved. For example, even if the harvesting work is performed under special conditions such as the harvesting operation of the grain straw lying on the field, the transport speed of the vertical transport chain 34 is adjusted to a speed suitable for the harvesting work of the lying grain straw. it can. Further, for example, in a combine that sandwiches and conveys the cereal stock by the feed chain 6 and supplies it to the threshing device 5, it is possible to prevent the cereal head side from being delayed and conveyed, so the required power of the threshing device 5 or threshing Loss etc. can be reduced.

  Further, as a low speed rotation setting device 266 as a minimum rotation number setting device for setting the minimum rotation number of the electric motor 92 for vertical conveyance driving, and as a maximum rotation number setting device for setting the maximum rotation number of the electric motor 92 for vertical conveyance driving. The high-speed rotation setting device 267 is provided, and the output of the electric motor 92 for vertical conveyance drive between the minimum rotation number set by the low-speed rotation setting device 266 and the maximum rotation number set by the high-speed rotation setting device 267. Since the rotational speed can be changed, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely low, the transport speed of the vertical transport chain 34 is not too slow, and the Can prevent clogging. Further, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely high, the transport speed of the vertical transport chain 34 does not become too fast, and it is possible to prevent the transport posture of the cereals being transported from being disturbed.

  As apparent from the above description and FIGS. 1, 6, and 7, the traveling machine body 1 provided with the traveling crawler 2 as the traveling portion that is operated by the engine 14 and the root of the cereal planted in the field are cut. The vertical conveying chain 34 is operated in a combine comprising a cutting blade device 222 and a vertical conveying chain 34 as a cereal conveying means for conveying the cereals whose stock has been cut by the cutting blade device 222. A vertical conveyance drive electric motor 92 and a culm sensor 287 as an end-of-cutting sensor for detecting the end of chopping of the cereal, when the end of chopping of the cereal is detected, 34 is configured to operate at a high speed, so that the grain of the vertical transport chain 34 is increased by the high speed operation of the vertical transport chain 34 at the end of cutting when the amount of cereals transported by the vertical transport chain 34 is reduced. Appropriately to maintain the conveying action, transfer terminal end side of the vertical conveying chain 34 (grain 稈受 joints), etc. In prevents culms spillage or 稈詰Ri occurs, it is possible to improve the conveyance performance of the vertical conveying chain 34.

  As is apparent from the above description and FIGS. 4, 6 and 7, the grain depth adjusting motor 94 is provided as a handling depth adjusting means for moving the vertical conveying chain 34 in and out of the machine body. At the end, the vertical transfer chain 34 is accommodated when the vertical transfer chain 34 is operated at a high speed and a predetermined time has elapsed. Therefore, when the cutting is finished, the vertical transfer chain 34 is stored. While the vertical transfer chain 34 is stored inside the machine body, it is possible to prevent the spillage or clogging from occurring at the grain cease transfer part or the like on the conveyance terminal side of the machine. Is executed. Therefore, it is not necessary for the operator to store the vertical conveyance chain 34, so that it is possible to prevent the vertical conveyance chain 34 from colliding with the bank or an obstacle around the bank when moving between fields or traveling on the road.

  As is apparent from the above description and FIGS. 4, 6, and 7, auxiliary stock source transport chains 35 and 36 serving as auxiliary transport means for inheriting and transporting the cereal straw from the vertical transport chain 34, Since the auxiliary conveying means is configured to operate at a high speed in association with the high speed operation of the vertical conveying chain 34 at the end of cutting of the reed, the vertical conveying chain 34 and the By the high-speed operation of the auxiliary conveying means, the vertical conveying chain 34 and the auxiliary conveying means can properly maintain the cereal conveying action, and spillage or clogging occurs at the conveying terminal side (the cereal inheriting part) of the vertical conveying chain 34 or the like. Occurrence can be prevented, and the conveyance performance of the vertical conveyance chain 34 can be improved.
