FIG. 3 is an enlarged view of the receiving unit 20 in FIG. In the first embodiment, portions different from the conventional example described in FIG. 17 will be described, and the same portions are denoted by the same reference numerals.

  The operation transmission unit 10 includes a wireless transmission unit 11, a battery 12, a charger 13, a wired priority switching circuit 14, a switch 15, and a connection unit 16. The switch 15 is a switch operated by an operator, and various switches are employed according to the operation content. The wireless transmission unit 11 wirelessly transmits an electrical signal generated by operating the switch 15. The battery 12 is a battery that supplies power for transmission or the like of the wireless transmission unit 11. The connection unit 16 is a connection unit such as a connector that can connect the connection unit 30 a of the wired connection harness 30. The wired priority switching circuit 14 is a circuit for recognizing that when the wired connection harness 30 is connected, canceling the transmission of the wireless transmission unit 11, and switching to wired communication by the wired connection harness 30. The charger 13 is a charger for charging the battery 12 with electric power from the wired connection harness 30 when the wired connection harness 30 is connected.

  The receiving unit 20 includes a wireless receiving unit 21, a battery 22, and a connecting unit 20a. The wireless reception unit 21 receives a signal transmitted from the wireless transmission unit 11 wirelessly. The battery 22 is installed as necessary, and necessary power is supplied to the wireless reception unit 21. In addition, the connection unit 23 c of the reception unit power supply harness 23 may be connected to the connection unit 20 a so that power is supplied from the battery 130. In this case, necessary power is supplied to the wireless reception unit 21 without the battery 22. Moreover, the radio | wireless receiving part 21 is connected to the receiving part harness 24 which has the connection part 24a.

  Next, a procedure for changing from the conventional wired system shown in FIG. 17 to the wireless system according to the first embodiment will be described. The operation unit 200 is replaced with the operation transmission unit 10. The connection harness 210 is removed because it is not used. And the connection part 100a of the control harness 100 and the connection part 24a of the receiving part 20 are connected. When the power is supplied from the battery 130 instead of the battery 22, the receiving unit power harness 23 of the receiving unit 20 is connected to the receiving unit 20, and the connecting unit 23 a of the receiving unit power harness 23 is connected to the connecting unit 131 a of the battery harness 131. And the connection part 23 b of the receiver power supply harness 23 is connected to the connection part 100 b of the control harness 100.

  Next, the operation will be described. When the operator operates the switch 15 of the operation transmission unit 10 to operate the output device 110, an operation signal generated by the operation is transmitted from the wireless transmission unit 11 to the wireless reception unit 21 of the reception unit 20 wirelessly. The operation signal received by the wireless reception unit 21 is sent to the control unit 120 through the reception unit harness 24 and the control harness 100. Then, based on this operation signal, the output device 110 is controlled through the control harness 100 under the control of the control unit 120.

The operation transmitting unit 10 is arranged on the tractor 1 side, and the operator can operate the switch 15 while getting on the tractor. On the other hand, by arranging the receiving side system such as the receiving unit 20 and the control unit 120 on the work machine 2 side, the connection harness 210 for operation is not necessary. And the power supply at that time can use the battery of the tractor 1 as the battery 130 as it is. Further, when the wireless function breaks down or when the battery 12 of the operation transmission unit 10 runs out, the wired connection harness 30 (two-dot chain line) is connected. Furthermore, when the power of the receiving unit 20 is taken from the battery 130 instead of the battery 22, the receiving unit power harness 23 (two-dot chain line) is connected.

  In addition, when obtaining power from the battery 130, the power from the battery 130 can be stably obtained in the receiver 20 by connecting the receiver power harness 23 as described above. A configuration in which the power of the power source is obtained from the connection portion 100a of the control harness 100 is also conceivable. In this case, the receiver power supply harness 23 is not provided, and the connection part 131a of the battery harness 131 and the connection part 100b of the control harness 100 are directly connected. Since the connection part 100a of the control harness 100 and the connection part 24a of the reception part harness 24 are connected, the power of the reception part 20 is supplied from the battery 130 via the battery harness 131, the control harness 100, and the reception part harness 24. Can be obtained. This configuration can also be applied to Example 2 described later.

The extension rake opening / closing device 60 rotates the extension rake 61 up and down around the rotation shaft 61a via the control bar 62 and the wire 63 as the internal motor rotates, and determines whether to use the extension rake 61 or not. Can be selected. The earthing unit 66 can adjust the earthing by controlling the vertical movement of the rake 65 through the earthing part 67 and the like by the rotation of an internal motor.

  The electric hydraulic cylinder 56, the extension rake opening / closing device 60 (motor), and the earthing unit 66 (motor) can be operated as the output device 110, and efficient farming work can be performed.

  FIG. 7 is a wiring diagram of the remote control system according to the second embodiment. FIG. 8 shows an enlarged view of the transmitter 40 in FIG. In the second embodiment, parts different from the conventional example and the first embodiment described in FIG. 17 will be described, and the same portions are denoted by the same reference numerals.

  The transmission unit 40 includes a wireless transmission unit 41 and a battery 42, and is connected to a transmission unit harness 43 having a connection unit 43a at an end. The wireless transmission part 41 transmits the operation content by the operation part 200 with a wireless signal. The battery 42 is a power source for supplying power to the wireless transmission unit 41 and the operation unit 200.

  Next, a procedure for changing from the conventional wired system shown in FIG. 17 to the wireless system according to the second embodiment will be described. The operation unit 200 is used as it is. The connection harness 210 is removed because it is not used. The connection part 43 a of the transmission part harness 43 is connected to the connection part 201 a of the operation part harness 201. And the connection part 100a of the control harness 100 and the connection part 24a of the receiving part 20 are connected. When the power is supplied from the battery 130 instead of the battery 22, the receiving unit power harness 23 of the receiving unit 20 is connected to the receiving unit 20, and the connecting unit 23 a of the receiving unit power harness 23 is connected to the connecting unit 131 a of the battery harness 131. And the connection part 23 b of the receiver power supply harness 23 is connected to the connection part 100 b of the control harness 100.

  Next, the operation will be described. When the operator operates the switch 203 of the operation unit 200 for operating the output device 110, the operation signal is sent to the wireless transmission unit 41 of the transmission unit 40 through the operation unit harness 201. Then, the wireless transmission unit 41 transmits the wireless signal to the wireless reception unit 21 of the reception unit 20. The operation signal received by the wireless reception unit 21 is sent to the control unit 120 through the reception unit harness 24 and the control harness 100. Based on the operation signal, the output device 110 is controlled by the control unit 120 through the control harness 100. The power required at that time is transmitted from the battery 130 to the output device 110 and the control unit 120 through the battery harness 131 and the control harness 100 (via the reception unit power supply harness 23 when the reception unit power supply harness 23 is connected).

  On the other hand, when the wireless function breaks down or when the battery 42 of the transmission unit 40 runs out, the transmission unit 40 and the reception unit 20 are removed, and the connection harness 210 that has been conventionally used is connected to the connection unit 201a of the operation unit harness 201. The part 210 a is connected and connected to the connection part 100 a of the control harness 100 and to the connection part 210 b of the connection harness 210. Accordingly, if the switch 203 of the operation unit 200 is operated, a wired operation can be performed through the connection harness 210 as in the conventional case. In addition, you may connect directly the connection part 201a of the operation part harness 201, and the connection part 100a of the control harness 100, without passing through the connection harness 210. FIG.

  FIG. 9 shows an example of the overall configuration when the remote control system of the second embodiment is applied to a farm machine. The operation unit 200 is arranged on the tractor 1 side, and an operator can operate the switch 203 while getting on the tractor. On the other hand, by arranging the receiving side system such as the receiving unit 20 and the control unit 120 on the work machine 2 side, the connection harness 210 for operation is not necessary. And the power supply at that time can use the battery of the tractor 1 as the battery 130 as it is. Further, when the wireless function breaks down or when the battery 42 of the transmission unit 40 runs out, the connection harness 210 (two-dot chain line) is connected. In FIG. 9, the connection portion 201 a of the operation unit harness 201 and the connection portion 100 a of the control harness 100 may be directly connected without using the connection harness 210. Furthermore, when the power of the receiving unit 20 is taken from the battery 130 instead of the battery 22, the receiving unit power harness 23 (two-dot chain line) is connected.

  4 and 9 in each of the above embodiments, the battery 130 has been described as the battery of the tractor 1. However, the present invention is not limited to this, and the battery 130 is installed on the work machine 2 side or installed on the work machine 2. It is also possible to use a generator. In this case, since the battery 130, the output device 110, and the control unit 120 are installed on the same work machine 2 side, a harness for connecting them can be simplified.

  FIG. 10 shows a wiring diagram in the remote control system of the third embodiment. FIG. 11 shows an enlarged view of the operation transmitter 10 'in FIG. FIG. 12 shows an example of the overall configuration when the remote control system of the third embodiment is applied to a farm machine. Example 3 demonstrates a different point from Example 1, and the same code | symbol is attached | subjected to the same location. In the third embodiment, the operation transmitter 10 'can be supplied with power from an external power source of the tractor.

  The external power supply harness 70 is a harness (wiring) having one end connected to the battery 130 included in the tractor and the other end serving as a connector of the connection portion 70a. Thereby, only when the switch 71 is turned on, the power of the battery 130 is supplied to the connecting portion 70a side. The switch 71 can be shared with the engine start switch of the tractor 1. For example, the switch 71 can be configured as a key switch that is turned on when a key for engine start is rotated. As a result, power can be supplied when the key switch (engine start switch) of the tractor is ON, and the connecting portion 70a can be connected to various devices as an external power source. The shape of the connection part 70a can be made into the connector shape prescribed | regulated by the Nichiko standard, for example.

  The operation transmission unit 10 ′ has an external power supply connection unit 81 and can connect (insert) the connector of the connection unit 70 a. At this time, power is supplied from the external power source connection unit 81 into the operation transmission unit 10 ′ such as the wireless transmission unit 11 and the charger 13. In FIG. 12, the external power source is connected via the connection harness 75. This can be extended in consideration of the length of the harness of the external power source provided in the tractor. Therefore, the connector of the connection part 70a of the external power supply harness 70 and the connector of the connection part 75a of the connection harness 75 have the same shape and can be connected to the external power supply connection part 81. Further, the connection part 75 b of the connection harness 75 can be connected to the connection part 70 a of the external power supply harness 70.

  By connecting an external power source to the external power source connection unit 81 and power is supplied from the external power source, the operation transmission unit 10 ′ can be used even if the battery 12 and the charger 13 are not provided. Weight reduction can be achieved. However, if the battery 12 and the charger 13 are provided, the charged battery 12 can be used without attaching an external power supply to the external power supply connection portion 81. It is possible to connect the connecting unit 70a) to other devices. Further, the battery 12 can be easily charged by connecting an external power supply so that the battery 12 can be charged while it is supplied from the external power supply.

  FIG. 13 is a wiring diagram of the remote control system according to the fourth embodiment. FIG. 14 shows an enlarged view of the transmitter 40 'in FIG. FIG. 15 shows an example of the overall configuration when the remote control system of the fourth embodiment is applied to a farm machine. Example 4 demonstrates a different point from Example 2 and 3, and the same code | symbol is attached | subjected to the same location. In the fourth embodiment, the power of the transmission unit 40 ′ and the operation unit 200 can be supplied from the external power supply of the tractor.

  The configuration of the external power supply harness 70 is the same as that of the third embodiment. The transmission unit 40 ′ has an external power supply connection unit 82, and can connect (insert) the connector of the connection unit 70 a. At this time, the power of the external power supply is supplied from the external power supply connection unit 82 to the operation unit 200 via the wireless transmission unit 41, the transmission unit 40 'such as the battery 42, and the operation unit harness 201. In FIG. 15, the connection harness 75 is used as in the third embodiment.

  By connecting an external power source to the external power source connection unit 82 and supplying electric power from the external power source, the transmission unit 40 ′ can be used without the battery 42, and cost and weight can be reduced. However, if the battery 42 is provided, the charged battery 42 can be used without attaching an external power supply to the external power supply connection portion 82, so that the battery 42 can be carried away or connected to the external power supply (connection portion 70 a). Can be used by connecting to other devices. Further, the battery 42 can be easily charged by connecting an external power supply so that the battery 42 can be charged while it is supplied from the external power supply.

  In the third and fourth embodiments, the remote control operation system in which power on the transmission side is supplied using an external power supply as a power supply has been described. However, in addition to this, a remote control operation system in which the power of the receiving unit 20 is supplied from an external power supply You can also

  FIG. 16 shows an example of the overall configuration when the remote control system of the fifth embodiment is applied to a farm machine. In the fifth embodiment, differences from the fourth embodiment will be described, and the same portions are denoted by the same reference numerals.

  The external power supply harness 70 (the connection portion 70a) is connected to the first harness 76 (the connection portion 76b), the first harness 76 is branched in the middle, and one (the connection portion 76c) is connected to the second harness. 77 (connecting portion 77b), and the second harness 77 (connecting portion 77a) is connected to the receiving unit 20. For this reason, the receiving unit 20 is supplied with power only from the external power source when the engine start switch 71 of the tractor 1 is ON. When the receiving unit 20 is directly connected to the battery 130, the receiving unit 20 is turned on so that the receiving unit 20 can receive a radio signal, and power is always consumed. For this reason, if power is supplied to the receiving unit 20 only when the switch 71 of the tractor is ON, useless power consumption of the battery 130 can be prevented.

  Moreover, the other (the connection part 76a) where the first harness 76 is branched is connected to the connection harness 75 (the connection part 75b), and the connection harness 75 (the connection part 75a) is connected to the transmission part 40 ′. It is connected. For this reason, as in the fourth embodiment, power can be supplied from the external power supply to the transmission unit 40 ′.

  The power of the control unit 120 and the output device 110 is supplied directly from the battery 130 via the battery harness 131 and the control harness 100. However, if the capacity supplied from the external power supply is sufficient, the power is supplied via the reception unit 20. It is also possible to obtain from the external power supply harness 70 side. Further, since the receiving unit 20 obtains electric power from an external power source, the receiving unit power harness 23 is not used, and the battery harness 131 (connecting portion 131b) and the control harness 100 (connecting portion 100b) are directly connected.

  In the fifth embodiment, the difference from the fourth embodiment has been described. Similarly, a configuration in which the power source of the receiving unit 20 of the third embodiment is an external power source is also applicable.
