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 constituted by a microcomputer, a work switch 273 that detects the drive of the threshing device 5 and the like, and the culm (uncut grain culm) of the culm pulling device 223. Alternatively, a culm sensor 287 that detects the culm (cut culm) of the culm conveying device 224, a vehicle speed sensor 285 that detects the moving speed of the traveling machine 1, and a rotative rotation sensor that detects the rotational speed of the chopping input shaft 17. 288, a conveyance speed setting dial 262 for steplessly adjusting the output rotation speed of the vertical conveyance drive electric motor 92 (the operation speed of the vertical conveyance chain 34), and the minimum output rotation speed (vertical rotation 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 operating speed of the transfer chain 34 and a maximum output rotation number (vertical transfer chain 34) of the electric motor 92 for vertical transfer driving. It connects the high speed setter 267 as the highest rotational speed setter for setting a maximum operating speed).

  Further, on the input side of the work controller 282, a manual forward switch 268 for manually operating the vertical transfer driving electric motor 92 and the tip transfer driving electric motor 93 in the cutting cereal conveying direction by manual operation, and the cutting cereal conveying direction In contrast, a manual reverse switch 269 that activates only the vertical transfer driving electric motor 92 by manual operation in a direction opposite to that of the vertical transfer drive, and a harvesting shift switch 270 that switches and operates the harvesting shift actuator 291 by manual operation (low speed, neutral, high speed operation). A constant rotation switch 271 for switching the constant rotation actuator 292 by manual operation (low speed constant rotation, neutral, high speed constant rotation operation) and a vertical conveyance rotation sensor for detecting the output rotation number of the electric motor 92 for vertical conveyance drive 312 and auxiliary conveyance for detecting the output rotation speed of the electric motor 93 for driving the tip conveyance And it connects the rolling sensor 313.

  As shown in FIG. 1, a pinch cover 246 provided with a pinch 245 for holding the harvested cereal by pressing the feed chain 6 is provided. The pinch cover 246 is disposed above the left side surface of the threshing device 5. An engine stop switch 247 that urgently stops the engine 14, a manual forward rotation switch 268, and a manual reverse rotation switch 269 are provided on the front end side of the outer side surface of the pinch cover 246. The engine stop switch 247, the manual forward rotation switch 268, or the manual reverse rotation switch 269 is operated from the left outer side of the traveling machine body 1 so as to execute a handling operation or a removal operation for clogged cereals. . As shown in FIG. 1, even if the manual forward rotation switch 268 and the manual reverse rotation switch 269 are provided on the harvesting left side cover 248 of the harvesting device 3, it is the same as the case where the switches 268 and 269 are provided on the pinching cover 246. In addition, while observing the clogged portion of the cereal, the manual forward rotation switch 268 or the manual reverse switch 269 can be operated to perform the operation of removing the culm.

  As shown in FIG. 7, the output side of the work controller 282 is connected to a vertical conveyance driver 302 that operates the vertical conveyance drive electric motor 92 and a tip conveyance driver 303 that operates the tip conveyance drive electric motor 93. 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. In addition, the tip transport driving electric motor 93 and the tip transport driver 303 are connected to the generator 89, and the tip transport driving electric motor 93 is 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 setting value of the conveyance speed setting dial 262, the output rotation speed of the vertical conveyance driving electric motor 92 is automatically controlled. During automatic control of the output rotation speed of the vertical conveyance drive electric motor 92, the operator manually operates the conveyance speed setting dial 262 to change the output rotation speed of the vertical conveyance drive electric motor 92 and The conveyance speed can be adjusted. The automatic control correlates the output rotation speed of the electric motor 92 for longitudinal conveyance drive 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. Can be changed.

  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 tip transfer driving electric motor 93 is reliably maintained, so that the roots of the cereal planted in the field can be cut. The vertical transfer driving electric motor 92 and the tip transfer driving electric motor 93 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 a tip 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). When the cutting input shaft 17 is operating below the set torque of the torque limiter 104, that is, when the cutting device 3 is not stopped (S4no), the detected value of the vehicle speed sensor 285, the detected value of the cutting rotation sensor 288, Then, the conveyance speed (vehicle speed synchronization speed) of the vertical conveyance chain 34 is calculated from the set value of the conveyance speed setting dial 262 (S5). Therefore, the operator can manually change the rotation speed of the vertical transfer driving electric motor 92 by manually operating the transfer speed setting dial 262. For example, even in a cutting operation under special conditions such as a cutting operation of cereals lying on the field, the vertical conveyance chain 34 can be operated at a speed adapted to the cutting operation.

  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 that case, the output rotational speed of the vertical transport driving electric motor 92 detected by the vertical transport rotation sensor 312 is relatively lower than the rotational speed of the cutting input shaft 17, and the cereal grains transported by the vertical transport chain 34. The stock market side is late and the tip side is in a transport posture. Conversely, when the traveling speed of the traveling machine 1 is reduced and the output rotational speed of the vertical transport driving electric motor 92 becomes relatively higher than the rotational speed of the cutting input shaft 17, the vertical transport chain 34 It becomes a conveyance posture in which the stock side of the cereal bowl conveyed by is preceded and the tip side is delayed.

  The detection value of the vertical conveyance rotation sensor 312 is read (S6), and the conveyance speed of the vertical conveyance chain 34 calculated in step 5 is compared with the detection value (actual conveyance speed) of the vertical conveyance rotation sensor 312. It is determined whether the transport speed of the transport chain 34 should be increased (S7) or the transport speed of the vertical transport chain 34 should be decreased (S12). When it is determined that the transport speed of the vertical transport chain 34 should be increased (S7yes), speed increase control for increasing the transport speed of the vertical transport chain 34 is executed (S8). As a result, the conveyance speed of the vertical conveyance chain 34 is accelerated in proportion to the movement speed of the traveling machine body 1, and the vertical conveyance chain 34 can be operated at a speed synchronized with the vehicle speed. 34 is not too slow, the posture of the cereals conveyed by the vertical conveying chain 34 is delayed on the stock side and the tip side is not preceded, and the cereals are clogged or being conveyed during the conveyance. Therefore, it is possible to prevent the vertical posture of the vertical conveying chain 34 from being disturbed.

  When the conveyance speed of the vertical conveyance chain 34 is increased by the speed increase control (S8) described above, the maximum operating speed setting value of the vertical conveyance chain 34 of the high-speed rotation setting device 267 is read (S9). When the conveyance speed of the vertical conveyance chain 34 matches the maximum operating speed setting value of the high-speed rotation setting device 267 and it is determined that the vertical conveyance chain 34 is operating at high speed (S10yes), the vertical conveyance chain 34 is kept constant. The rotation control is executed (S11). Even if the moving speed (vehicle speed) of the traveling machine body 1 is further increased, the conveyance speed of the vertical conveyance chain 34 is maintained at the set value of the high-speed rotation setting device 267 by the constant rotation control (S11) of the vertical conveyance chain 34. . That is, since the vertical conveyance chain 34 is configured to operate at a speed equal to or lower than the rotational speed set by the high-speed rotation setting device 267, even when the moving speed (vehicle speed) of the traveling machine body 1 is extremely high, The conveying speed of the vertical conveying chain 34 and the auxiliary conveying chains 35 and 36 does not become too fast, and the vertical conveying chain 34 (the electric motor 92 for vertical conveying drive) can be prevented from operating in an overloaded state. It is possible to reduce the disturbance of the transport posture or damage to the vertical transport chain 34.

  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 that case, the output rotational speed of the vertical transport driving electric motor 92 detected by the vertical transport rotation sensor 312 is higher than the rotational speed of the cutting input shaft 17, and the stock side of the cereals transported by the vertical transport chain 34 is Prior to that, the tip side is delayed.

  When the rotational speed of the cutting input shaft 17 is compared with the output rotational speed of the vertical transport driving electric motor 92, it is determined that the vertical transport driving electric motor 92 needs to be decelerated (S12yes). Deceleration control is performed to decelerate the conveyance driver 302 and decelerate the conveyance speed of the vertical conveyance chain 34 (S13). As a result, the conveyance speed of the vertical conveyance chain 34 is decelerated in proportion to the moving speed (vehicle speed) of the traveling machine body 1 by the deceleration control (S13), and the vertical conveyance chain 34 can be operated at a speed synchronized with the vehicle speed. The transport speed of the vertical transport chain 34 does not become too fast compared to the movement speed of 1, and the posture of the cereals transported by the vertical transport chain 34 is not delayed by the head side and the tip side is delayed. It is possible to prevent clogging of grain halves on the way or disturbance of the conveyance posture of corn straw during conveyance, and the conveyance performance of the vertical conveyance chain 34 can be improved.

  When the conveyance speed of the vertical conveyance chain 34 is decelerated by the above-described deceleration control (S13), the minimum operating speed setting value of the vertical conveyance chain 34 of the low-speed rotation setting device 266 is read (S14). When it is determined that the vertical transport chain 34 is operating at a low speed because the vertical transport chain 34 operates at a low speed, the transport speed of the vertical transport chain 34 matches the minimum operating speed setting value of the low speed rotation setting device 266 (S15yes), constant rotation control (S11) of the vertical conveyance chain 34 is executed. Therefore, even if the moving speed (vehicle speed) of the traveling machine body 1 is further decelerated, the conveyance speed of the vertical conveyance chain 34 is maintained at the set value of the low-speed rotation setting device 266 by the constant rotation control (S10) of the vertical conveyance chain 34. The That is, since the vertical conveyance chain 34 can be operated at a speed equal to or higher than the rotational speed set by the minimum rotational speed setting unit 266, even when the traveling speed (vehicle speed) of the traveling machine body 1 is extremely slow, The conveyance speed does not become too slow, the cereals during conveyance can be prevented from being clogged, and the conveyance performance of the vertical conveyance chain 34 can be maintained.

  Furthermore, during the cutting operation in which the above-described acceleration control (S8), constant rotation control (S11), and deceleration control (S13) 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 at high speed is executed for an initial setting time (for example, about 10 seconds). The vertical conveyance chain 34 is operated at a higher speed than the constant rotation control (S10) in which the conveyance speed of the vertical conveyance chain 34 is maintained at the set value of the high-speed rotation setting device 267. Therefore, it is possible to prevent spillage or clogging from occurring at the conveyance end side (grain culm transfer part) of the vertical conveyance chain 34 or the like.

  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.

  Next, referring to FIG. 8, the vertical conveyance drive electric motor 92 and the tip conveyance drive electric motor 93 are operated to remove the cereals clogged in the conveyance start end side and during conveyance of the vertical conveyance chain 34. The removal operation of the clogged cereal meal is described. In a state where the work switch 273 is not turned on (S1no), or in a state where the culm sensor 287 is not turned on (S2no), or during the cutting operation, a load higher than the set torque of the torque limiter 104 is generated, and the cutting device is caused by overload. 3 is stopped, when the harvested cereals are jammed in the transport path of the vertical transport chain 34 (S4 yes), the operator sitting on the driver's seat 12 performs an operation to stop the traveling crawler 2 and the harvester 3. Thereafter, the operator moves to the left side of the traveling machine body 1 provided with the manual forward rotation switch 268 and the manual reverse rotation switch 269.

  When the operator turns on the manual forward rotation switch 268 while visually checking the harvested culm jammed in the transport path of the vertical transport chain 34 (S16 yes), the trimming stop control is executed (S17), and the trimming shift actuator 291 is performed. Is maintained at the cutting shift output OFF position (neutral position), and the constant rotation actuator 292 is maintained at the constant rotation output OFF position (neutral position). In this case, only the reaping device 3 is stopped and maintained, and the threshing device 5 and the feed chain 6 are operated at a substantially constant speed by the power from the engine 14. That is, when the manual operation is turned on (S16yes), the cutting stop control and the manual rotation control are executed in a state where the threshing device 5 and the feed chain 6 are continuously operated. Therefore, the vertical conveyance chain 34 can be operated by operating the manual forward rotation switch 268 while confirming the clogging status of the cereals or the conveyance status of the cereals. The vertical conveying chain 34 can be operated only for the time required to remove the clogging cereals on the conveying start end side or during the conveying of the vertical conveying chain 34.

  In the manual rotation control, when the manual forward rotation switch 268 is turned on (S16yes), the vertical conveyance driving electric motor 92 and the tip conveyance driving electric motor 93 are operated, and the vertical conveyance driving electric motor 92 performs the vertical conveyance chain. 34 operates in the cutting grain haul conveyance direction, and the rear-tip conveying tine 38 operates in the mowing grain haul conveying direction by the electric motor 93 for driving the tip movement. Therefore, the harvested culm on the feed start end side of the vertical transport chain 34, which is the grain merging portion of the right stock transport chain 33R and the left stock transport chain 33L, or the harvested culm in the middle of the transport of the vertical transport chain 34 is sent. It is transported toward the end side. As a result, it is possible to remove the cereal straw that is clogged during the conveyance start end side of the vertical conveyance chain 34 or during the conveyance.

  When the vertical transport drive electric motor 92 and the tip transport drive electric motor 93 are rotated forward by turning on the manual forward switch 268, the vertical transport chain 34 and the rear tip transport tine 38 are controlled at a constant rotation (S11). It operates at a conveyance speed slower than the minimum operation speed set value of the low speed rotation setting device 266 to be executed. Therefore, the vertical conveying chain 34 can be easily operated by an appropriate amount according to the clogging status of the cereals or the conveying status of the cereals. The vertical conveyance chain 34 can be operated by the conveyance movement amount necessary to remove the clogged cereals on the conveyance start end side or during the conveyance of the vertical conveyance chain 34. In addition, by operating the rear tip transport tine 38 along with the vertical transport chain 34 in the cutting and grain transport direction, the rear tip transport tine 38 prevents the head side of the cereal from being handled and sheds grains, It is possible to prevent the former side from being in the preceding conveying posture, and to reduce the disturbance of the conveying posture of the cereal at the feed start end of the feed chain 6 or the like.

  In the manual rotation control, when the operator turns on the manual reversing switch 269 (S16yes), the turning operation of the manual reversing switch 269 keeps the tip transport driving electric motor 93 off and the vertical transport driving electric motor 92. Only the reverse rotation operation is performed, and the vertical conveyance chain 34 is operated by the vertical conveyance driving electric motor 92 in the direction opposite to the harvested cereal conveyance direction. Therefore, the cut grain culm on the middle of feeding of the vertical conveying chain 34 or the feeding terminal side is conveyed toward the feeding start end side of the vertical conveying chain 34. As a result, it is possible to disperse and remove cereal cakes packed in the middle of conveyance of the vertical conveyance chain 34 toward the feed start end side.

  Even when the vertical conveyance drive electric motor 92 is activated by turning on the manual reverse switch 269, the vertical conveyance chain 34 operates at a conveyance speed slower than the minimum operation speed setting value of the low-speed rotation setting device 266. Therefore, the vertical conveyance chain 34 can be operated in reverse by the amount of conveyance movement necessary for removing the clogged culm during the conveyance of the vertical conveyance chain 34. Moreover, the removal operation | work of a clogging cereal needs only to reversely operate only the vertical conveyance chain 34 which pinched | interposed the stock source of the cereal, and the reverse rotation of the back tip conveyance tine 38 is unnecessary.

  As is clear from the above description and FIGS. 1, 6, 7, and 8, the traveling machine body 1 having the traveling crawler 2 as the traveling unit that is operated by the engine 14, and the cereal planted in the field A cutting blade device 222 that cuts the base, a vertical transport chain 34 as a cereal transporting means for transporting the cereal that has been cut by the cutting blade device 222, and a vehicle speed sensor that detects the moving speed of the traveling machine body 1 285, a vertical conveyance drive electric motor 92 that operates the vertical conveyance chain 34 at a vehicle speed synchronization speed synchronized with the moving speed of the traveling machine body 1 detected by the vehicle speed sensor 285, and a vertical conveyance drive electric motor. A manual forward rotation switch 268 or a manual reverse rotation switch 269 serving as a manual operation member for actuating 92 by manual operation, and the traveling crawler 2 or the cutting blade device 222 is stopped The vertical conveying drive electric motor 92 is configured to be operable by operating the manual forward rotation switch 268 or the manual reverse rotation switch 269, so that the cereal grains conveyed by the vertical conveyance chain 34 are clogged during the harvesting operation. However, it is possible to easily remove the cereals packed in the vertical conveying chain 34 in the field during the harvesting operation. Troublesome work such as disassembling the vertical transfer chain 34 can be omitted. Even if the vertical conveying chain 34 is clogged with cereals, the cereals can be easily released, the harvesting operation can be resumed smoothly, and the reaping efficiency of the cereals can be improved.

  As is clear from the above description and FIGS. 7 and 8, the manual forward rotation switch 268 or the manual reverse rotation switch 269 is disposed on the outer surface of the traveling machine body 1, while visually checking the cereal conveyance status of the vertical conveyance chain 34. Since the manual forward rotation switch 268 or the manual reverse rotation switch 269 can be operated from the outside of the traveling machine body 1, the manual forward rotation switch is checked while checking the clogging state of the cereal or the transporting state of the cereal. The vertical conveyance chain 34 can be operated by operating the H.268 or manual reverse switch 269. The vertical conveying chain 34 can be operated for the time required to remove the stuffed cereal and the cereal cereal can be easily released. Damage to the vertical transfer chain 34 can be prevented.
