Power can be supplied to each device from the motor 83d for waste processing unit. Thus, the waste disposal processing unit 60 is configured to supply power from the waste disposal processing unit motor 83d. However, the exclusion processing unit motor 83d may be a plurality of motors, and power may be supplied to each device from separate motors.

  Therefore, in the combine 1, when power is supplied from the second engine 80 to the generator 81, power is generated by the generator 81, and the power generated by the generator 81 is charged in the battery 82. When the electric power charged in the battery 82 is converted from DC power to AC power by each inverter of the inverter group 84 and supplied to each motor of the motor group 83, each motor is activated. At this time, the rotation speed of each motor in the motor group 83 is controlled by each inverter in the inverter group 84.

  The motor rotation number detection means 97 detects the rotation speed of each motor in the motor group 83, and the respective motors are controlled by the control means 90 based on these detected values. Changed to be a number. As a result, the input shaft of the apparatus in each working unit is rotated at a predetermined rotational speed. However, instead of detecting each motor rotation speed, it is also possible to detect the rotation speed of the input shaft of the apparatus in each working unit and control each motor by the control means 90 based on the detected value.

  In addition, the output power of the generator 81 is detected by the generator output detection means 89, the remaining charge amount of the battery 82 is detected by the remaining charge detection means 91, and the second engine 80 is controlled based on these detected values. Controlled by the means 90 and the second ECU 85, the rotational speed of the second engine 80 is changed. Specifically, the second engine 80 is controlled in the following flow, and its operating state is changed.

  That is, as shown in FIG. 4, in the state where the first engine 70 and the second engine 80 are operated, the remaining charge of the battery 82 is first detected by the remaining charge detection means 91 (S1), and the detected value Whether or not C0 exceeds the first set value C1 is determined by the control means 90 (S2). The first set value C1 is set in advance as a threshold for determining the start of charging of the battery 82.

  As a result of this determination, if the detected value C0 exceeds the first set value C1, the second engine 80 is stopped by the control means 90 and the second ECU 85 (S3). In this case, since the battery 82 is sufficiently charged and each motor of the motor group 83 is operable, the second engine 80 and thus the generator 81 are stopped.

  If the detected value C0 is equal to or less than the first set value C1, then control A is performed (S4). As shown in FIG. 5, in the control A, first, the control means 90 determines whether or not the detected value C0 exceeds the second set value C2 (S5). The second set value C <b> 2 is smaller than the first set value C <b> 1, and is set in advance to a value that can store a certain amount of power in the battery 82 and supply power to each motor in the motor group 83.

  As a result of this determination, if the detected value C0 is equal to or smaller than the second set value C2, the second engine 80 is operated (S6). On the other hand, if the detection value C0 exceeds the second set value C2, it is determined based on the detection result of the threshing state detection means 94 whether or not the threshing state is in operation (S7).

  If the result of this determination is that it is not a threshing state, it is determined that a non-harvesting operation is in progress, and the second engine 80 is stopped by the control means 90 and the second ECU 85 (S8). In this case, since each motor of the motor group 83 can operate under a certain condition, the second engine 80 and thus the generator 81 are stopped.

  If it is a threshing state, it is determined whether or not it is a cutting state in which the cutting unit 20 is operating (S9). As a result of this determination, if it is in the cutting state, it is determined that the harvesting operation is being performed, and the second engine 80 is activated (S6). In this case, it is determined whether or not the detection value of the generator output detection means 89 exceeds a predetermined value. If the detection value is equal to or less than the predetermined value, the second engine 80 is rotated by the control means 90 and the second ECU 85. It is supposed to operate to increase the number.

  If not in the cutting state, based on the detection value detected by the supply guide position detecting means 96, the supply guide 32 is in either the working position p1 that is the cutting work position or the non-working position p2 that is the handling work position. Is determined (S10). If the result of this determination is that the supply guide 32 is in the operating position p1, the second engine 80 is operated (S6).

  On the other hand, if the supply guide 32 is in the non-operating position p2, it is determined that the handling operation is being performed, and the second engine 80 is stopped by the control means 90 and the second ECU 85 (S8). In this case, since each motor including the threshing unit motor 83a can be operated under a certain condition, the second engine 80 and thus the generator 81 are stopped.

  Further, even when the second engine 80 is stopped as a result of the control as described above, it is determined at any time whether or not the detection value C0 detected by the remaining charge detection means 91 exceeds the third set value. . If the detection value C0 is equal to or less than the third set value, the second engine 80 is forced to operate. The third set value is smaller than the second set value C2, and is set to a necessary minimum value for operating each motor of the motor group 83 or a value slightly larger than that.

  The handling operation is performed in a state where the traveling unit 10 is not operated, that is, the traveling of the combine 1 is stopped and the cutting unit 20 is not operated. From this, when the supply guide 32 is set to the non-operation position p2, it is determined that the handling operation is being performed as described above, and the first engine 70 is stopped by the control means 90 and the first ECU 75. Is possible. In this case, during the handling operation, the first engine 70 can be appropriately stopped to reduce fuel consumption, and vibration and noise can be reduced.

  As mentioned above, the combine 1 which concerns on one Embodiment of this invention is the threshing part 30 which threshs the traveling part 10 which makes an airframe drive | run, the cutting part 20 which reaps the grain cocoon, and the mash which has been cut by the cutting part 20; The sorting unit 40 for sorting the grains threshed by the threshing unit 30, the grain processing unit 50 for storing or discharging the grains sorted by the sorting unit 40, and the waste after threshing by the threshing unit 30 A first engine 70 that supplies power to the traveling unit 10 and the reaping unit 20, a threshing unit 30, a sorting unit 40, a grain processing unit 50, and a waste processing.

When the engine speed of the second engine 80 is controlled and the detected value C0 detected by the remaining charge detecting means 91 exceeds the first set value C1 set to start charging the battery 82, the second engine 80 is to be stopped.

  Thus, power can be supplied from the first engine 70 to the traveling unit 10 and the reaping unit 20 to operate these working units, and the threshing unit 30, the sorting unit 40, and the cereal from the motor group 83. Power can be supplied to the grain processing unit 50 and the waste processing unit 60 to operate each of these working units. Therefore, the first engine 70 and the second engine 80 are small and have a small displacement so that the fuel consumption can be reduced.

  In addition, the second engine 80 can be efficiently controlled according to the working state, that is, appropriately stopped according to the situation without operating wastefully. Therefore, the fuel consumption can be reduced by making the second engine 80 small and having a small displacement. In addition, since power is supplied from the motor group 83 to the working units other than the traveling unit 10 and the cutting unit 20, these working units can be stably operated, and work efficiency can be improved.

Is the non-operation position p2, the second engine 80 is stopped.

  Thereby, when the handling operation is performed by moving the supply guide 32 to the non-operation position p2, the second engine 80 may not be operated more than necessary while each motor of the motor group 83 is operable. It becomes possible. Therefore, during the handling operation, the second engine 80 can be appropriately stopped to reduce fuel consumption, and vibration and noise can be reduced.

Which position is present can be detected.

  A motor rotation number detection means 194 comprising a rotation sensor or the like is provided. Specifically, as the motor rotation speed detection means 194, a traveling section motor rotation speed detection means 194a and a reaping section motor rotation speed detection means 194b are provided. The motor speed detection means 194 can detect the motor speed of the corresponding first motor group 173. From this detection value, the traveling speed, the cutting speed, and the like can be detected.

  Control means 190 is provided. The control means 190 includes a central processing unit (CPU) that executes various arithmetic processes, a read-only memory (ROM) that stores control programs, and a readable / writable memory that temporarily stores various programs and data. (RAM) or the like.

  Control means 190 is also connected to first ECU 175. In addition, the control means 190 is connected to each motor of the first motor group 173 via an inverter of the first inverter group 174 corresponding thereto. Specifically, the control unit 190 is connected to the traveling unit motor 173a via the inverter 174a and to the cutting unit motor 173b via the inverter 174b.

  Then, when the speed change lever is operated, the set travel speed is detected by the set travel speed detection means 109 based on the operation, and the travel section motor 173a is controlled by the control means 190 based on the detected value. The operating state is changed. That is, when the operation of the speed change lever in the speed increasing or deceleration direction is performed, the traveling unit motor 173a is operated so as to have a preset rotational speed set in advance according to the operation of the speed change lever. The However, a switch or the like can be used instead of the lever as a means for performing the shifting operation.

  When the cutting switch 102 is turned ON / OFF, the cutting unit motor 173b is controlled by the control unit 190 based on the operation, and its operating state is changed. When the reaping switch 102 is turned on, the reaping portion motor 173b is operated so as to have a preset rotational speed. This set rotational speed is set so that the cutting speed is synchronized with the traveling speed. When the cutting switch 102 is turned off, the cutting unit motor 173b is stopped. However, a lever or the like can be used instead of the switch as means for performing the cutting operation. The cutting switch 102 is included in the operation means and provided in the control unit 9. In this configuration, the cutting clutch switch 6 and the cutting clutch 25 described above are omitted.

  When the travel switch 103 is pressed, the travel unit motor 173a is controlled by the control unit 190 based on the operation, and the operating state thereof is changed. That is, when the travel switch 103 is pressed, the travel unit motor 173a is operated to rotate a certain amount. As a result, the combine 1 travels forward by a predetermined distance at a low speed when the travel switch 103 is pressed. The travel switch 103 is provided on a threshing cover or the like in the threshing unit 30 so as to be positioned in the vicinity of the supply guide 32, and can be operated by an operator who performs a handling operation.

  The motor rotation speed detection means 194 detects the rotation speed of each motor of the first motor group 173, and the respective motors of the first motor group 173 are controlled by the control means 190 based on these detection values. The number is changed to be the set rotation speed. As a result, the input shaft of the apparatus in each working unit is rotated at a predetermined rotational speed. However, instead of detecting each motor rotation speed, it is also possible to detect the rotation speed of the input shaft of the apparatus in each working unit and control each motor by the control means 190 based on the detected value.

  In addition, the output power of the first generator 171 is detected by the first generator output detection means 179, the remaining charge of the first battery 172 is detected by the first remaining charge detection means 191, and these detected values are obtained. Based on this, the first engine 170 is controlled by the control means 190 and the first ECU 175, and the rotational speed of the first engine 170 is changed. Specifically, control of the first engine 170 is performed according to the following flow, and the operating state is changed.

  That is, as shown in FIG. 8, in the state where the first engine 170 and the second engine 180 are operated, first, the remaining charge of the first battery 172 is detected by the first remaining charge detection means 191 (S21). Then, the control means 190 determines whether or not the detected value C0 exceeds the first set value C1 (S22). The first set value C1 is set in advance as a threshold for determining the start of charging of the first battery 172.

  As a result of this determination, if the detected value C0 exceeds the first set value C1, communication between the control means 190 and the first ECU 175 is performed, and the first engine 170 is stopped by the first ECU 175 (S23). . In this case, since the first battery 172 is sufficiently charged and each motor of the first motor group 173 is operable, the first engine 170 and thus the first generator 171 are stopped.

  If the detected value C0 is equal to or less than the first set value C1, then control B is performed (S24). As shown in FIG. 9, in the control B, first, it is determined by the control means 190 whether or not the detected value C0 exceeds the second set value C2 (S25). The second set value C2 is smaller than the first set value C1, and is set in advance to a value that can store power of a certain capacity in the first battery 172 and supply power to each motor of the first motor group 173.

  If the detection value C0 is equal to or smaller than the second set value C2 as a result of this determination, the first engine 170 is operated (S26). On the other hand, if the detected value C0 exceeds the second set value C2, based on the detected value detected by the supply guide position detection means 193, the supply guide 32 is at the action position p1 that is the cutting work position and the handling work position. It is determined which one of the non-acting positions p2 is present (S27).

  If the result of this determination is that the supply guide 32 is in the operating position p1, the first engine 170 is operated (S26). On the other hand, if the supply guide 32 is in the non-operating position p2, it is determined that the handling operation is being performed, and the first engine 170 is stopped by the control means 190 and the first ECU 175 (S28). In this case, since the traveling unit motor 173a can be operated under a certain condition, the first engine 170 and thus the first generator 171 are stopped.

  When the travel switch 103 is pressed during the handling operation in which the supply guide 32 is set to the non-operating position p2, the travel unit motor 173a operates so as to rotate a certain amount, and combines. 1 is assumed to travel forward at a low speed for a predetermined distance. Thereby, the stop position of the combine 1 can be changed.

  Further, even when the first engine 170 is stopped as a result of the control as described above, it is determined at any time whether or not the detected value C0 detected by the first remaining charge detection means 191 exceeds the third set value. Is done. When the detected value C0 becomes equal to or smaller than the third set value, the first engine 170 is forced to operate. The third set value is less than or equal to the second set value, and is set to a necessary minimum value for operating each motor of the first motor group 173 or a value slightly larger than that.

  As described above, in the combine 1, the first motor group 173 that supplies power to the traveling unit 10 and the cutting unit 20, that is, the traveling unit motor 173 a, the cutting unit motor 173 b, and each motor of the first motor group 173. A first battery 172 for supplying power to the battery, a first generator 171 for charging the first battery 172, a first engine 170 for operating the first generator 171, and a remaining charge of the first battery 172 are detected. The first remaining charge detection means 191, the first engine speed detection means 192 that detects the engine speed of the first engine 170, the threshing section 30, the sorting section 40, the grain processing section 50, and the waste processing section 60. A second motor group 183 that supplies power to the threshing portion, that is, a threshing portion motor 183a, a sorting portion motor 183b, a grain processing portion motor 183c, a waste disposal portion motor 183d, and a second A second battery 182 that supplies power to each motor of the data group 183, a second generator 181 that charges the second battery 182, a second engine 180 that operates the second generator 181, and a second battery 182 Second charge remaining amount detecting means for detecting the remaining charge amount, second engine speed detecting means for detecting the engine speed of the second engine 180, the first engine 170, the second engine 180, and the first motor group. 173 and control means 190 for controlling each motor of the second motor group 183, and the control means 190 is an engine of the first engine 170 based on the detected value C 0 detected by the first remaining charge detection means 191. The rotation speed is controlled, and a detection value C0 detected by the first charge remaining amount detection means 191 is set to a first set value C1 set to start charging the first battery 172. When rotating, the first engine 170 is stopped, the engine speed of the second engine 180 is controlled based on the detection value detected by the second remaining charge detection means, and the second remaining charge detection means It is also possible to stop the second engine 180 when the detected value detected by the above exceeds a first set value set to start charging the second battery 182.

  Thus, power can be supplied from the first motor group 173 to the traveling unit 10 and the reaping unit 20 to operate these working units, and the threshing unit 30 and the sorting unit can be operated from the second motor group 183. Power can be supplied to 40, the grain processing unit 50, and the waste processing unit 60, and each of these working units can be operated. Therefore, the first engine 170 and the second engine 180 are small and have a small displacement so that the fuel consumption can be reduced.

  In addition, the first engine 170 and the second engine 180 can be efficiently controlled according to the working state, that is, appropriately stopped according to the situation without operating wastefully. Therefore, the first engine 170 and the second engine 180 are small and have a small displacement so that the fuel consumption can be reduced. In addition, since power is supplied from the motor to each working unit, the working unit can be operated stably without being affected by the engine load as compared with the case where power is supplied from the engine. Efficiency can be improved.

  Moreover, in the combine 1, the action position p1 which pinches | interposes the grain straw from the cutting part 20 with the conveyance start end part of the feed chain 31 as a conveying apparatus of the threshing part 30, and guides it to the feed chain 31 side, and action position p1 A supply guide 32 capable of switching the position to the non-operation position p2 retracted from the position, and a supply guide position detection means 193 for detecting the position of the supply guide 32. The control means 190 includes first charge remaining amount detection means. When the detected value C0 detected by 191 is less than or equal to the first set value C1 and exceeds the second set value C2 that can supply power to each motor of the first motor group 173, the supply guide 32 is inoperative. The first engine 170 can be stopped at the position p2.

  Accordingly, when the handling operation is performed by moving the supply guide 32 to the non-operation position p2, the traveling unit motor 173a of the first motor group 173 can be operated, that is, the combine 1 can be traveled. It is possible to prevent the engine 170 from operating more than necessary. Therefore, the first engine 170 can be appropriately stopped during the handling operation to reduce fuel consumption, and to reduce vibration and noise.

  In the combine 1, it is also possible to provide a travel switch 103 in the vicinity of the supply guide 32 as operation means for operating the travel unit motor 173 a of the first motor group 173.

  Thus, when the operator who performs the handling operation operates the travel switch 103, the traveling unit motor 173 a is operated from the vicinity of the supply guide 32, that is, from the vicinity of the cereal supply port in the threshing unit 30, and the combine 1 travels. It becomes possible to make it. Therefore, the operator can easily drive the combine 1 by operating the travel switch 103 on the spot. For example, when there is no culm after cutting from the worker, there is corn after harvesting. The combine 1 can be moved to a place. Moreover, when discharging the waste after the processing by the waste processing unit 60 to the field, the discharged waste can be diffused and can be prevented from accumulating in one place.
