The generator 81 is connected to the engine 80 and is driven by the rotation of the engine 80 being transmitted.
A battery 82 is provided at the right rear end of the machine body 2. The battery 82 is electrically connected to the generator 81 and can store the electric power generated by the generator 81.

Below, the power transmission of the combine 1 is demonstrated.
The combine 1 supplies the power of the engine 80 to the traveling unit 10, the threshing unit 30, the sorting unit 40 (excluding the red pepper 42a), the grain storage unit 50, and the waste processing unit 60 via a power transmission system including a transmission. These parts are driven by the power of the engine 80.
Moreover, the combine 1 is the electric motor (three-phase alternating current motor) 91a and 92a regarding each part (the reel 21, the cutting blade 22, the PF auger 23, and the FH conveyor 24) of the cutting part 20, and the Karatsu 42a of the selection part 40. • Driven by the power of 93a, 94a, and 95a (see FIG. 5).

  Next, the configuration of the electric motors 91a, 92a, 93a, 94a, 95a and peripheral devices will be described.

  As shown in FIG. 4, during normal travel (when the engine 80 is rotating), the generator 81 is driven by the engine 80 to generate AC power. This AC power is converted into DC power by the inverter 83. The DC power is converted into AC power by inverters 192, 193, and 194 and supplied to the electric motors 92a, 93a, and 94a, respectively. Further, the DC power is adjusted in voltage by the DC-DC converter 84, converted into AC power by the inverters 191 and 195, and supplied to the electric motors 91a and 95a, respectively. Therefore, when the power consumption is less than the generated power, the reel 21, the cutting blade 22, the PF auger 23, the FH conveyor 24, and the red pepper 42 a are driven by the power from the generator 81, and surplus power is stored in the battery 82. Further, when the power consumption is greater than the generated power, the battery 82 also supplies power.

  When the engine 80 is stopped, the electric power stored in the battery 82 is supplied to the electric motors 91a, 92a, 93a, 94a, and 95a via the inverters 191, 192, 193, 194, and 195, respectively. Therefore, when the engine 80 is stopped, the reel 21, the cutting blade 22, the PF auger 23, the FH conveyor 24, and the red pepper 42 a are driven by the electric power from the battery 82.

As shown in FIG. 5, operating devices 71, 72, 73, 74, and 75 and inverters 191, 192, 193, 194, and 195 are connected to the control device 100.
The control device 100 receives the signals from the operation tools 71, 72, 73, 74, and 75, thereby controlling the inverters 191, 192, 193, 194, and 195 to control the electric motors 91a, 92a, 93a, 94a, and 95a. Manipulate the rotation of. Thereby, the control apparatus 100 controls operation | movement of the reel 21, the cutting blade 22, the PF auger 23, the FH conveyor 24, and the Kara 42a.

Conventionally, the power of the engine has been configured to be transmitted to each part of the cutting unit and the tang through a plurality of transmission belts and pulleys.
On the other hand, the combine 1 according to the present embodiment includes the electric motors 91 a, 92 a, and the electric motors 91 a, 92 a, and the parts of the cutting unit 20 (the reel 21, the cutting blade 22, the PF auger 23, and the FH conveyor 24) and the Kara 42 a of the sorting unit 40. 93a, 94a and 95a are connected to each other, and each part of the cutting unit 20 and the carp 42a are individually driven by the power of the electric motors 91a, 92a, 93a, 94a and 95a. Thereby, parts for connecting to the engine, such as a conventionally used transmission belt and transmission pulley, can be deleted, and a power transmission system to the cutting unit 20 and the tang 42a can be simplified. Further, regarding each part of the cutting unit 20 (reel 21, cutting blade 22, PF auger 23, and FH conveyor 24) and the tang 42a of the sorting unit 40, the power transmission system is different from the power transmission system with the engine 80. Therefore, regardless of the engine 80, the output shafts of the electric motors 91a, 92a, 93a, 94a, and 95a can be rotated to facilitate maintenance and adjustment.

  In addition, the combine 1 has a power source (electric motors 91a, 92a, 93a, 94a, and 95a) for the parts that should be adjusted in rotation speed according to the work situation (each part of the cutting unit 20 and the tang 42a). By providing this, each rotational speed is configured to be adjustable. And about the site | part (threshing part 30 and the generator 81) which require a fixed rotational speed, the engine 80 is used as a power source. Thus, the combine 1 is improving workability | operativity by providing multiple types of power sources in consideration of the characteristic of each part.

  As shown in FIG. 2, the combine 1 is provided with electric motors 91 a, 92 a, 93 a, and 94 a in the cutting unit 20, and a battery 82 at the rear end of the machine body 2 (behind the grain storage unit 50). This is because the center of gravity of the combine 1 is biased forward by providing the electric motors 91 a, 92 a, 93 a, and 94 a in the cutting unit 20, but the weight balance before and after the combine 1 is provided by providing the battery 82 at the rear end of the machine body 2. This is to suppress the deviation of the center of gravity. Thereby, the posture of the combine 1 can be stabilized.

Thereby, it becomes possible to transmit the rotation of the electric motor 95a for tangling to the tangling 42a without using a pulley, a belt member or the like, and it is possible to make the power transmission system to the tangling 42a compact.

A reduction gear 95b is provided between the output shaft 95d of the red pepper electric motor 95a and the rotary shaft 42d of the red pepper 42a. The speed reducer 95b is composed of, for example, a planetary gear mechanism and is accommodated in a case 95e. The rotation of the output shaft 95d of the red pepper electric motor 95a is decelerated by the speed reducer 95b and then transmitted to the red collar 42a, thereby driving the red collar 42a. By providing the speed reducer 95b, it is possible to obtain low speed and high torque with a small motor.
In this way, the red pepper drive device 95 generates power for driving the red pepper 42a by the red pepper electric motor 95a and the speed reducer 95b.

Thereby, it is possible to suppress the protrusion amount (protrusion of the red pepper drive device 95) that the red pepper drive device 95 protrudes laterally from the body 2. In this embodiment, the red pepper electric motor 95a protrudes to the outside (left side) of the side plate 45. However, the present invention is not limited to this. 95a may also be arranged on the inner side (right side) of the side plate 45. Thereby, it is possible to further suppress the allowance for the drive device 95 for red pepper.

  The combine 1 is configured so that when the fuselage side cover 5 is attached to the side of the fuselage 2 (outside the side plate 45), the tangling drive device 95 does not get in the way by suppressing the allowance for the drive device 95 for red pepper. ing.

In the above embodiment, the red pepper drive device 95 is composed of the red pepper electric motor 95a and the speed reducer 95b.
