  The remote control operation unit 30 has an operation panel 31 on the surface, and an operation button 32 which is an operation switch there. The operation button 32 forms the number required for operation of the agricultural machine mounted on the tractor. The remote control operation unit 30 includes a transmission unit that wirelessly transmits a signal generated by operating the operation button 32. Further, if necessary, a wireless reception function can be added to form a transmission / reception unit. Note that a side surface of the remote control operation unit 30 has a gradient portion 33 that forms a gradient in a direction in which the area decreases toward the surface. This can be formed using, for example, a draft angle of resin.

  On the other hand, a battery storage unit 35 is provided on the back surface of the remote control operation unit 30, and the battery 201 is stored in the recess as a shape. The battery 201 can store a necessary number. In addition, the inner surface of the battery storage unit 35 has a plurality of contacts 35 a that contact the positive electrode terminal and the negative electrode terminal of each battery 201. In FIG. 1, three batteries 201 are housed side by side in the vertical direction, and the contacts 35a are provided on the upper and lower inner surfaces. Further, the battery storage unit 35 is installed in a lower part than the center on the back surface of the remote control operation unit 30.

  Further, the cover 36 can be mounted near the outside (rear side) of the battery storage part 35, and the battery storage part 35 in which the battery 201 is stored can be covered with the cover part 36a. A packing 37 can be attached along the periphery between the cover 36 and the battery storage unit 35.

Further, the cover 36 can be firmly fixed to the remote control operation unit 30 by fixing with the fixing screw 38. In FIG. 1, the fixing portion 36 b is disposed on the lower side of the cover 36. In addition, when the cover 36 is attached, the back surface of the remote control operation unit 30 is substantially flat.

  With these configurations, the power source of the remote control operation unit 30 can be provided by the battery 201.

  FIG. 2 shows one embodiment when the power connection component is mounted by the remote control device for agricultural machinery of the present invention, (a) is a side view before connection of the power connection component, and (b) is a power connection component. A side view of the connected state, (c) is a rear view of the state where the power supply connection components are connected.

  When the battery 201 has run out in the state of FIG. 1, the operator removes the cover 36 from the remote control operation unit 30, removes the battery 201, and instead connects the power connection component 40 to remove the battery from the tractor. Enables power supply. Thereby, the operation by the remote control operation unit 30 can be continued.

  The power connection component 40 includes a battery storage side connection portion 41, a cover portion 42, a harness portion 43, a power connector 44, a wiring 45, and an external connector 46. The battery housing side connection portion 41 and the cover portion 42 form a main body portion 49 of the power supply connection component 40.

  The battery storage side connection portion 41 is a portion that is inserted into the battery storage portion 35 and has a contact 41 a that contacts the contact 35 a of the battery storage portion 35 on the side surface. The contact 41a is provided at a position in contact with the contact 35a necessary for supplying power. For this reason, there are at least a plurality of contacts 41a. For example, when the battery 201 is connected in series, the positions of the two contacts 41a at the end and end of the series (if there are three batteries, the left and right and top and bottom are (Symmetry position).

  The cover part 42 is formed integrally with the battery storage side connection part 41 and is formed wider than the battery storage side connection part 41. The battery storage part 35 is replaced with the battery storage side connection part 41 in place of the cover 36. It covers everything. For this reason, the battery storage side connection part 41 has a step part 42 a to the outside from the cover part 42. When the packing 80 is attached to the stepped portion 42a, the packing 80 is interposed between the cover portion 42 and the remote control operation portion 30 along the periphery of the battery storage portion 35 side. Thereby, a waterproof and dustproof function can be exhibited. Further, a converter 48 described later is built in the main body 49. The cover part 42 has a certain thickness as required.

  The fixing portion 47 is formed so as to extend on the same plane as the cover portion 42, and is fixed with a fixing screw 38 in the same manner as the cover 36, so that the main body portion 49 is remote-controlled while covering the battery storage portion 35 with the cover portion 42. The operation unit 30 can be firmly fixed via the packing 80.

  The harness portion 43 is a harness having wiring for electrically connecting the main body portion 49 and the power connector 44. The connection part 43a of the harness part 43 is connected to the cover part 42, and the connection part 43a protrudes outward (back side) so as not to interfere with the remote control operation part 30 (so that the cover part 42 can be covered). .

  When the main body 49 is attached to the remote control operation unit 30, the back surface of the remote control operation unit 30 is flat as when the cover 36 is connected. And the connection part 43a of the harness part 43 protrudes to the outer side (back side), and the harness part 43 is extended toward the lower side from there.

  The power connector 44 is a connector that can be connected to a connection portion from a power source included in the tractor. For example, it is possible to connect to a power supply connection portion 12a as an external power supply connected from a battery 11 included in the tractor 1 described later in FIG. At this time, when the connecting portion 12a of the tractor 1 conforms to the Nichiko standard, the power connector 44 can have a connector shape defined by the Nichiko standard.

  The wiring 45 is a wiring branched from the power connector 44 separately from the wiring of the harness portion 43, and is connected to the external connector 46.

  The external connector 46 is a connector for connecting to another output device. By making it the same as the shape in the power supply connection part 12a from the power supply which the tractor 1 has, it can connect to the connector of the output device which can be connected to the power supply connection part 12a.

  FIG. 3 is a schematic diagram showing a circuit state of the power supply connection component in the first embodiment of the remote control device for agricultural machinery according to the present invention. The battery 11 of the tractor 1 is connected to the converter 48 in the main body 49 through the external power supply harness 12 and the harness 43 connected thereto. The converter 48 converts the voltage A on the battery 11 side into a voltage B that matches the remote control operation unit 30. And it connects to the remote control operation part 30 via the contact 41a which the battery storage side connection part 41 has, and the contact 35a of the battery storage part 35. For example, 12 V, which is the voltage A of the battery 11, is converted to 4.5 V, which is the voltage B of the remote control operation unit 30. The voltage B of 4.5V is an example assuming a case where three dry batteries are connected in series.

  FIG. 4 is a schematic plan view showing an example of an arrangement of a tractor and a farm machine to which the remote controller for a farm machine according to the present invention is applied. The present invention can be applied to an agricultural machine 2 that is attached to the tractor 1 and performs agricultural work. The tractor 1 has a battery 11, and the agricultural machine 2 has a wireless transmission / reception unit 21, a control unit 22, and an actuator 23. The battery 11 can be used as a power source for the tractor 1.

  An external power supply harness 12 is connected to the battery 11, and the tip of the battery 11 is a power supply connection portion 12a via a switch 12b. The power supply connection part 12a can connect a power supply to an external apparatus. The switch 12b can be shared with the engine start switch of the tractor 1. For example, the switch 12b can be configured as a key switch that is turned on when a key for engine start is rotated. Thereby, useless power consumption when the work by the tractor 1 is not performed can be prevented. In addition, the shape of the connector 12a can be made into the connector shape prescribed | regulated by the Nichiko standard, for example.

  When the battery 201 is used as the power source of the remote control operation unit 30, the power connection part 40a is not directly used and the power connection part 12a of the external power harness 12 is directly connected to the connector 25a of the work machine side harness 25. The For this reason, it is possible to operate the devices on the farm work machine 2 side such as the wireless transmission / reception unit 21, the control unit 22, and the actuator 23 by using the battery 11 as a power source.

  On the other hand, when the battery 201 is not used as the power source of the remote control operation unit 30, the power connection component 40 is connected to the remote control operation unit 30. The power connection portion 12 a of the external power harness 12 is connected to the power connector 44 of the power connection component 40. On the other hand, the external connector 46 of the power connection component 40 is connected to the connector 25 a of the work machine side harness 25. For this reason, it is possible to operate the remote control operation unit 30 and the devices on the farm work machine 2 side such as the wireless transmission / reception unit 21, the control unit 22, and the actuator 23 using the battery 11 as a power source.

  When the operator operates the remote control operation unit 30, an operation signal from the remote control operation unit 30 is sent to the wireless transmission / reception unit 21, and the control unit 22 activates the actuator 23. A specific example of the actuator 23 will be described later. In addition, information from the control unit 22 may be transmitted from the wireless transmission / reception unit 21 to the remote control operation unit 30 as necessary.

  FIG. 5 is a rear view showing an example of a farm machine to which the remote controller for a farm machine according to the present invention is applied. FIG. 6 is a front view showing an example of a farm machine to which the farm machine remote control device of the present invention is applied. The farm work machine 2 in FIGS. 5 and 6 is a scraping work machine 50 provided with a folding mechanism, and the input shaft 51 side is attached to the tractor 1 and power from the tractor 1 is input via the input shaft 51 to cover The scratching work is performed by rotating the scratching claw inside the 52 and the first leveling body 53. An example of the actuator 23 will be described using the scraping work machine 50.

  The electro-hydraulic cylinder 56 can be expanded and contracted so that the rotation mechanism 57 is actuated to fold the side working portion 55 inward (as shown on the left side in FIG. 6) to shorten the entire width of the scraper 50. . The extended leveling body driving device 60 rotates the extended leveling body 61 around the rotation shaft 61a via the arm 62 and the wire 63 and rotates the extended leveling body 61 outward by rotating the internal motor. You can choose whether to fold inward. The second leveling body driving device 66 rotates the second leveling body 65 via the second leveling body link means 67 and rotates the second leveling body 65 so as to be fixed at the lower side. It is possible to select whether to make a normal scraping state in which the rotation is not fixed.

  The electric hydraulic cylinder 56, the extended leveling body driving device 60 (or its motor), and the second leveling body driving device 66 (or its motor) can be operated as an actuator 23 by operating the remote control operation unit 30.

  In addition, as an example of the actuator 23, it is not limited to a scraper working machine, but can be widely applied as long as it is an actuator used in a farm working machine that is attached to a tractor and performs farming work.

The installation can be performed using a plurality of mounting holes 140, and a method such as hooking the first mounting hole 141 to the hook is also conceivable. Further, it may be attached to the back portion 110 with a magnet or a double-sided tape.

  The notch portion 130 formed in the holder 100 is a hole for discharging when the soil adhering to the remote control operation unit 30 accumulates in the holder 100. It is possible to prevent the remote control operation unit 30 from becoming unremovable due to the dirt accumulated in the interior and water from being accumulated in the holder. It is possible to easily discharge soil and water by installing a plurality of notches 130 on the side. In the example of the figure, it is formed on both sides between the back surface part 110 and the side part, and the first notch part 131, the second notch part 132, and the third notch part 133 are formed on both sides from the upper side. . The lowermost third notch 133 can be enlarged to easily discharge the accumulated soil.

Further, the second protrusion 162 is hooked and stopped in the middle of the gradient portion 33 on the lower lateral surface of the remote control operation unit 30.

  When the operator takes out the remote control operation unit 30 from the holder 100 from the state of FIG. 8, the operator grasps the remote control operation unit 30 near the upper lateral side surface 152 having a low height and pulls it out from the holder 100 to the surface side. At this time, the first projection 161 and the second projection 162 are pushed along the slope portion 33 and slightly deformed by the elasticity of the upper side surface portion 151 and the lower lateral side surface portion 154, and the first projection 161 and the first projection The remote control operation unit 30 can be pulled out over the two protrusions 162. Simultaneously, the harness part 43 is taken out from the groove | channel 170 currently opened to the surface side. Further, when the remote control operation unit 30 is mounted on the holder 100, it can be mounted over the first projection 161 and the second projection 162 due to the elasticity of the upper side surface portion 151 and the lower lateral side surface portion 154.

  In FIG. 8, the case where the power supply connection component 40 is connected to the remote control operation unit 30 has been described for installation in the holder 100, but the case where the power supply connection component 40 is not connected to the remote control operation unit 30 (battery 201. The remote control operation unit 30 can be held by the holder 100 even when the is attached). As can be seen from FIG. 8, the remote control operation unit 30 can be attached to the holder 100 even in a configuration in which the harness portion 43 and the connection portion 43 a do not exist.

  FIG. 9 is a schematic diagram showing a circuit state of the power supply connection component in the second embodiment of the remote control device for agricultural machinery according to the present invention. The second embodiment has a configuration in which a capacitor 85 is added to the power supply connection component 40, and the rest is the same as the first embodiment.

  Capacitor 85 is connected in parallel with converter 48, and is connected to a circuit closer to remote controller operation unit 30 (on the side opposite to battery 11) than converter 48. The capacitor 85 is disposed in the main body 49 of the power connection component 40 and can store a certain amount of electrical energy.

  By having the capacitor 85, the capacitor 85 is charged when the power supply connecting component 40 is connected to the power supply (battery 11). In a state where the power connection component 40 is not connected to a power source, the remote control operation unit 30 can be used for a certain period of time using the capacitor 85 as a power source.

  For example, when the operator wants to use the remote control operation unit 30 away from the driver seat of the tractor 1, the worker cannot move beyond the length of the harness unit 43. At this time, even if the power connection component 40 is removed from the power connection 12 a of the external power harness 12, the remote control operation unit 30 can be used for a certain period of time, and the actuator 23 can be operated. For example, this is effective when the agricultural machine 2 is being washed or when it is desired to confirm the operation of the actuator 23 of the agricultural machine 2 after getting off the tractor 1. Although it depends on the capacity of the capacitor 85, it can be several minutes to several tens of minutes as the fixed time that can be used here.

  10A and 10B are diagrams showing a third embodiment of the remote control device for agricultural machinery according to the present invention, where FIG. 10A is a front view showing the operation panel 31 of the remote control operation unit 330, and FIG. It is a schematic rear view including the block diagram of the remote control operation part 330 at the time, and (c) shows a schematic rear view including a block diagram when the power connection component 340 which is a DC adapter is mounted instead of the battery 201. Compared with the first and second embodiments, the third embodiment has a configuration in which control based on connection determination of power connection components is added, and a voltage detection unit 311 is added. In the third embodiment, portions added to the first embodiment and the second embodiment and different portions will be described, and the same portions as the first embodiment and the second embodiment are denoted by the same reference numerals.

  As shown in FIG. 10A, the operation panel 31 of the remote control operation unit 330 includes a power button 32a, an operation button 32b, and an indicator lamp 318. These configurations can also be applied to the remote control operation unit 30 of the first and second embodiments.

  The power button 32a is provided on the upper portion of the operation panel 31, and by pressing the button, the power source of the remote control operation unit 330 can be turned from OFF (off) to ON (on) or from ON to OFF. At this time, it is also possible to turn on the power by pressing it for a certain period of time (for example, within a few seconds) so that the power is not turned on by mistake.

  The operation button 32b is a switch for operating a device on the farm work machine 2 side such as the actuator 23 of the farm work machine 2, and a plurality of buttons are arranged as necessary. For example, the safety can be enhanced by operating the actuator 23 only while the operation button 32b is being pressed.

  The indicator lamp 318 is disposed at an easily understandable position on the operation panel 31, and is disposed beside the power button 32a in FIG. The indicator lamp 318 can be applied to notify the power supply state, communication state, and battery capacity. Specific examples will be described later.

  As shown in FIGS. 10B and 10C, the remote control operation unit 330 includes a voltage detection unit 311, a remote control operation unit control unit 312, a transmission / reception unit 315, and a wiring 316.

  The voltage detection unit 311 detects a voltage between the contact point 41a of the battery 201 and the power supply connection component 340. That is, in the state of FIG. 10B in which the battery 201 is mounted in the battery storage unit 35 of the remote control operation unit 330, the (output) voltage of the battery 201 is detected via the wiring 316. If it is in series, the voltage between the ends of the series is detected. If it is in parallel, the voltage between the batteries 201 is detected. Further, in the state of FIG. 10C in which the power supply connection component 340 is mounted on the battery storage unit 35 of the remote control operation unit 330 (output between the contacts 41a of the battery storage side connection unit 41 corresponding to the battery 201). ) The voltage is detected via the wiring 316. The voltage detection unit 311 can be configured by an IC or a resistor, for example.

  The remote control operation unit control unit 312 is configured by a CPU or the like, and controls the remote control operation unit 330. The remote control operation unit control unit 312 performs control of FIG. 11 described later based on the voltage detected by the voltage detection unit 311. In addition, control is performed to transmit a signal by the operation button 32 from the transmission / reception unit 315. The voltage detection unit 311 may be configured in the remote control operation unit control unit 312.

  The transmission / reception unit 315 wirelessly transmits an operation signal from the operation button 32 to the wireless transmission / reception unit 21 on the farm work machine 2 side. Further, if necessary, it is also possible for the transmission / reception unit 315 to wirelessly receive information from the control unit 22 from the wireless transmission / reception unit 21 and send the information to the control unit 312 for remote control operation unit.

  The power connection component 340 has the same shape as the power connection components 40 of the first and second embodiments. However, as described later, the voltage between the contacts 41a (B in FIGS. 3 and 9) is changed to the voltage by the battery 201. Set to be larger. The rest is the same as the power supply connection component 40.

  When using the battery 201 as a power source, the remote control operation unit 330 has a function of turning on the standby mode or turning off the power after a certain time in order to reduce the power consumption of the battery. An example in this case is shown in S110 to S118 of FIG. Here, in the standby mode or when the power is turned off, the actuator 23 cannot be moved immediately even if the operation button 32 of the remote control operation unit 330 is pressed. If the power is off, the power needs to be turned on again. If the power is in the standby mode, control for canceling the standby mode is required, and a certain time is required. The configuration of the remote control operation unit 330 other than that described in the third embodiment is the same as that of the remote control operation unit 30 described with reference to FIGS.

  FIG. 11: is a flowchart which shows the control in Example 3 of the remote control device for agricultural machines of this invention. The control of FIG. 11 is performed by the remote control operation unit control unit 312.

  First, when control is started (S101), it is determined whether or not the power connection component 340 is connected to the remote control operation unit 330 (S102). The determination in S102 may be performed after the power button 32a is pressed. The determination in S102 will be described later. As a result, if it is determined that the power connection component 340 is connected, the remote control operation unit 330 is turned on (S103), and the DC adapter mode is set (S104).

  This state is the same as the state (S111) immediately after the battery 201 is turned on by the power button 32a. Also, on the agricultural machine 2 side, when the wireless transmission / reception unit 21 and the control unit 22 are OFF, information is received from the transmission / reception unit 315 and these are turned ON. In this state, continuous communication is performed between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the agricultural machine 2 side. At this time, if the operation button 32b is operated, the actuator 23 can be immediately operated with good response. During this control, unlike S111 described later, the standby mode is not entered. For this reason, it is necessary to set the control of S103 and S104 as control different from the control of S111.

  On the other hand, as another control method, there is a control method in which the DC adapter mode is continued while using the control of S110 to S113 described later. As one of the standby mode conditions, when the operation button 32 is not operated for a certain period of time, the standby mode is entered. Instead of the signal input by operation of the operation button 32 at a time interval shorter than the certain time, the power signal The control which gives the signal etc. is added and it does not shift to standby mode. In the case of a power signal, for example, a signal having a time shorter than the reaction time is given by continuing to press the power button 32a, and the power is not turned off by this signal, and the standby mode is entered. To prevent.

  Further, this state is maintained while it is determined that the power connection component 340 is connected to the remote control operation unit 330 (S105). If it is determined that the power supply connection component 340 is not connected to the remote control operation unit 330, the power supply of the remote control operation unit 330 is turned off (S106). This is the same as the state of S118 in which the power button 32a is turned off when the battery 201 is mounted, and communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side is not performed.

  The determinations in S102 and S105 described above are performed based on the voltage detected by the voltage detection unit 311. In general, a battery has a certain width with respect to a rated (nominal) voltage. For example, if the displayed rated voltage is a battery of DC 1.5V, the actual voltage may have a maximum of about 1.7V, and the voltage will drop according to use and drop below 1.0V. It is.

  Here, the voltage between the contacts 41a of the power supply connection component 340 is set to a voltage within the effective voltage operable by the remote control operation unit control unit 312 and higher than the assumed voltage of the battery 201. Thus, when this voltage is detected by the voltage detection unit 311, the remote control operation unit control unit 312 can determine whether or not the power supply connection component 340 is connected due to the difference in voltage.

  For example, when three 1.5V batteries 201 are connected in series and the rated voltage is 4.5V, the actual maximum voltage of the battery is 1.7 (V) × 3 = 5.1 (V ) Is assumed. At this time, if a voltage higher than 5.2 (V) or the like is output between the contacts 41a of the power connection component 340, the voltage of the battery 201 and the voltage of the power connection component 340 can be distinguished. . That is, the maximum voltage output by the assumed battery 201 <the voltage output between the contacts 41a of the power supply connection component 340.

  Further, the remote control operation unit control unit 312 may be operated at any of the above voltages. For example, in the above-described example, it is sufficient to operate in the range up to about 10V.

  If the remote controller operation unit 330 is continuously turned on by the DC adapter mode of S104, the operator can immediately operate the output device such as the actuator 23 with the operation button 32b. At this time, since it is connected to the power source of the tractor 1 by the power connection component 340, power can be secured from the battery 11 or the like, so that the capacity is larger than that of the battery 201, and the problem of power consumption is reduced.

  If it is determined in S102 of FIG. 11 that the power connection component 340 is not connected, it is determined whether or not the power button 32a is turned on (S110). When a signal that is an ON condition by pressing the power button 32a or the like is detected, the remote control operation unit 330 is turned on (S111). Also, on the agricultural machine 2 side, when the wireless transmission / reception unit 21 and the control unit 22 are OFF, information is received from the transmission / reception unit 315 and these are turned ON. This state is a state in which continuous communication is performed between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the agricultural machine 2 side. When the power supply connection component 340 is not connected, battery use is assumed. When the battery 201 is not inserted or when the battery 201 has no capacity, the power button is not turned on, and the power source of the remote control operation unit 330 is not turned on.

  On the other hand, when the power button is turned off by pressing the power button 32a again while the power is on, the remote control operation unit 330 is turned off (S112, S118). If the power is on as it is, the standby mode condition is determined (S113), and if the condition is met, the standby mode is set (S114).

  The standby mode condition is that the communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side is changed from continuous communication to intermittent communication when the operation button 32 is not operated for a certain time. It is to switch. The intermittent communication in the standby mode performs communication at intervals as compared with the continuous communication in S111, and is, for example, an interval of several seconds to several tens of seconds. By switching to intermittent communication, the consumption of the battery 201 can be suppressed more than when continuous communication is performed.

  To return from the standby mode, when the operation button 32 is pressed during the standby mode, the communication is switched from the intermittent communication to the continuous communication of S111, and the normal operation can be performed. However, when switching to continuous communication, it takes some time, and the operator does not feel that the actuator 23 operates with good response.

  On the other hand, if the power button 32a is turned off by pressing the power button 32a again for a predetermined time or more in the standby mode, the power source of the remote control operation unit 330 is turned off (S115, S118). On the other hand, if the power is on as it is, the auto power off mode condition is determined (S116), and if the condition is met, the auto power off mode is set, and the remote control operation unit 330 is powered off (S117, S118).

  The auto power off mode condition is to set the auto power off mode when the operation button 32 is not operated for a certain period of time. This is the same as when the power is turned off by operating the power button 32a. At this time, the power source of the remote control operation unit 330 is turned off, and communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the agricultural machine 2 side is not performed. Thereby, the consumption of the battery 201 is extremely small. Further, the reception function of the wireless transmission / reception unit 21 on the farm work machine 2 side can also be turned off, and the control unit 22 may be turned off. The fixed time of the auto power off mode condition is longer than the time for shifting to the standby mode condition, and can be applied, for example, between several minutes to several hours.

  As other auto power-off mode conditions, intermittent communication between the transmission / reception unit 315 of the remote control operation unit 330 and the wireless transmission / reception unit 21 on the farm work machine 2 side is performed during standby mode (because radio waves do not reach). Auto power-off mode may be set when it is not possible for a certain period of time. This is because if it is not possible to communicate with the wireless transmission / reception unit 21 on the agricultural machine 2 side, it is assumed that the operation cannot be performed even after returning from the standby mode. The fixed time in this case is shorter than the fixed time when the operation button 32 is not operated, and is, for example, several minutes to several tens of minutes.

  To return from the auto power off mode, it is necessary to perform an ON operation by pressing the power button 32a as in S110. When the power button 32a is pressed (in some cases for a certain period of time), the remote control operation unit 330 is turned on. Also, on the agricultural machine 2 side, when the reception function of the wireless transmission / reception unit 21 and the control unit 22 are turned off, it is necessary to turn them on. For this reason, recovery from the auto power off mode takes longer to start than recovery from the standby mode.

  As another control, when the voltage of the battery 201 has dropped, the indicator lamp 318 informs the user, and when the voltage drops further, the remote controller operation unit 330 may be turned off. . This is because the capacity of the battery is lost if the voltage of the battery 201 decreases. For example, the above control is performed when a voltage of about several tens of the rated voltage drops.

  The display of the indicator lamp 318 can be notified of the state by changing the display color or by separately displaying lighting and blinking. For example, when the power source of the remote control unit 330 is ON, green is lit, when the radio transceiver unit 21 on the agricultural machine 2 side is in a range where radio waves reach, the red color is lit, and when the battery capacity is low It blinks red and turns off when the power source of the remote control operation unit 330 is OFF.

  FIG. 12: shows the figure in Example 4 of the remote control operating device for agricultural machines of this invention, (a) shows the side view of the power supply connection component 440, (b) shows the front view of the power supply connection component 440, FIG. 4C is a schematic rear view including a block diagram when the battery 201 is attached to the remote control operation unit 430. In the fourth embodiment, points different from the third embodiment are described, and the same portions as those in the first to third embodiments are denoted by the same reference numerals.

  The fourth embodiment is different from the third embodiment in the control for determining the connection of the power supply component in S102 and S105 of FIG. In the fourth embodiment, the determination is based not on the voltage difference but on the connection of the contacts, and the power connection component 440 has a configuration for that purpose.

  The power connection component 440 has a plate-like contact connection member 410. The contact connecting member 410 is formed of a material (electric conductor) that conducts electricity, such as a copper plate. Contact 417 is formed inside packing 480. In FIG. 12, the contact connection member 410 is formed on the storage side (front side) surface of the cover portion 442 between the battery storage side connection portion 441 and the packing 480. The battery storage side connection part 441, the cover part 442, and the packing 480 have the same functions as the battery storage side connection part 41, the cover part 42, and the packing 80 described with reference to FIG. In order to secure the space, the shape may be changed as necessary. The power supply connection component 440 does not need to change the output voltage unlike the power supply connection component 340 of the third embodiment. The configuration of the power connection component 440 other than that described in the fourth embodiment is the same as that of the power connection component 40 described in FIG.

  The remote control operation unit 430 includes a power connection component connection confirmation input unit 411, a remote control operation unit control unit 412, a transmission / reception unit 315, a wiring 416, and a contact 417. The configuration of the remote control operation unit 430 other than that described in the fourth embodiment is the same as that of the remote control operation unit 30 described with reference to FIGS.

  The two wirings 416 are connected to two contact points 417 at their tips. The two contacts 417 have a certain distance, and are electrically connected via the contact connection member 410 when the power connection component 440 is connected to the remote control operation unit 430. For this reason, the contact connecting member 410 has a length corresponding to the distance between at least two contacts 417. Further, the two contact points 417 may be extendable and contractable by using an elastic member in the connection direction (the back surface direction of the remote control operation unit 430) so that the contact point connection member 410 can be easily connected. In FIG. 12 (c), the contact 417 is installed on the upper part of the battery storage unit 35 in the remote control operation unit 430. When the power connection component 440 is attached to the remote control operation unit 430, the contact connection member 410 has two contact connection members 410. The contact 417 is disposed at a position to which the contact 417 is connected. At this time, the two contact points 417 are also located inside the packing 480.

  The power supply component connection confirmation input unit 411 detects when the two contacts 417 are electrically connected via the contact connection member 410.

  The remote control operation unit control unit 412 is configured by a CPU or the like, and controls the remote control operation unit 430, and performs control based on information detected by the power connection component connection confirmation input unit 411. In addition, control for transmitting a signal by the operation button 32 from the transmission / reception unit 315 is also performed. The power connection component connection confirmation input unit 411 may be configured in the remote control operation unit control unit 412.

  The determination of the connection of power supply components in S102 and S105 of FIG. 11 will be described. When the battery 201 is mounted in the battery storage unit 35 of the remote control operation unit 430, the two contact points 417 are separated from each other, and nothing is interposed between them, so the power connection component connection confirmation input unit 411 is between the contact points. Do not check for energization. In this case, the remote control operation unit control unit 412 determines that the power connection component 440 is not connected. On the other hand, when the power supply connection component 440 is mounted on the battery storage unit 35 of the remote control operation unit 430, the two contacts 417 on the remote control operation unit 430 side are connected via the contact connection member 410 on the power supply connection component 440 side. The component connection confirmation input unit 411 detects energization between the contacts. In this case, the remote control operation unit control unit 412 determines that the power connection component 440 is connected.

  FIG. 13 shows a diagram of a remote control operation device for agricultural machinery according to a fifth embodiment of the present invention, where (a) shows a front view of the power supply connection component 540, and (b) shows that the battery 201 is mounted on the remote control operation unit 530. The schematic rear view including the block diagram of time is shown. In the fifth embodiment, differences from the third embodiment will be described, and the same portions as those in the first to third embodiments are denoted by the same reference numerals.

  The fifth embodiment is different from the third embodiment in the control for determining the connection of the power supply component in S102 and S105 of FIG. In the fourth embodiment, the determination is based not on the voltage difference but on the pressing of the microswitch, and the power connection component 540 has a configuration for that purpose.

  The power connection component 540 has a switch contact surface 510. The switch abutment surface 510 may have a protruding shape, a flat shape, or a recessed shape as required. The switch contact surface 510 is formed inside the packing 580. In FIG. 13, it is formed on the storage side (front side) surface of the cover portion 542 between the battery storage side connection portion 541 and the packing 580. The battery storage side connection part 541, the cover part 542, and the packing 580 have the same functions as the battery storage side connection part 41, the cover part 42, and the packing 80 described in FIG. In order to secure the space, the shape may be changed as necessary. Further, the power connection component 540 according to the fifth embodiment does not need to change the output voltage unlike the power connection component 340 according to the third embodiment. The configuration of the power connection component 540 other than that described in the fifth embodiment is the same as that of the power connection component 40 described in FIG.

  The remote control operation unit 530 includes a power connection component connection confirmation input unit 511, a remote control operation unit control unit 512, a transmission / reception unit 315, a wiring 516, and a micro switch 517. The configuration of the remote control operation unit 530 other than that described in the fifth embodiment is the same as that of the remote control operation unit 30 described with reference to FIGS.

  The two wirings 516 are connected to the microswitch 517 at their respective tips. When the micro switch 517 is not pressed and turned off, the two wires 516 are not connected, and when the micro switch 517 is pushed and turned on, the two wires 516 are connected. The micro switch 517 protrudes in a direction in which the micro switch 517 comes into contact with the switch contact surface 510 (the back surface direction of the remote control operation unit 530), and when pressed by the switch contact surface 510, the front direction of the remote control operation unit 530 (the battery storage unit 35). Retracted to the back side) and turned ON. When the switch is not pushed by the switch contact surface 510, it is restored to the projecting direction by using an elastic member or the like and turned OFF. In FIG. 13B, the micro switch 517 is installed on the upper part of the battery storage unit 35 in the remote control operation unit 530, and when the power connection component 540 is attached to the remote control operation unit 530, the switch contact surface 510 is The micro switch 517 is pushed to be turned on. At this time, the microswitch 517 is also located inside the packing 580.

  The power connection component connection confirmation input unit 511 detects when the microswitch 517 is pressed and turned on to electrically connect the two wires 516.

  The remote control operation unit control unit 512 is configured by a CPU or the like, and controls the remote control operation unit 530, and performs control based on information detected by the power connection component connection confirmation input unit 511. In addition, control for transmitting a signal by the operation button 32 from the transmission / reception unit 315 is also performed. The power connection component connection confirmation input unit 511 may be configured in the remote control operation unit control unit 512.

  The determination of the connection of power supply components in S102 and S105 of FIG. 11 will be described. When the battery 201 is mounted in the battery storage unit 35 of the remote control operation unit 530, the micro switch 517 is not pressed, and the power connection component connection confirmation input unit 511 does not confirm the energization between the two wires 516. In this case, the remote controller operation unit controller 512 determines that the power connection component 540 is not connected. On the other hand, when the power connection component 540 is attached to the battery storage unit 35 of the remote control operation unit 530, the micro switch 517 on the remote control operation unit 530 side is pressed by the switch contact surface 510 on the power connection component 540 side to be turned on. The connection component connection confirmation input unit 511 detects energization between the two wires 516. In this case, the remote controller operation unit controller 512 determines that the power connection component 540 is connected.

  FIG. 14: shows the figure in Example 6 of the remote control device for agricultural machines of this invention, (a) is a side view before connecting the power supply connection component 640 to the remote control operation part 30, (b) is a remote control operation part. 30 is a side view in a state where the power connection component 640 is connected, and (c) is a rear view in a state where the power connection component 640 is connected to the remote control operation unit 30. FIG. 15 also shows a diagram in Embodiment 6 of the remote control device for agricultural machinery according to the present invention, in which (a) is a front view showing a state in which the remote control operation unit 30 to which the power connection component 640 is connected is mounted on the power holder 700. FIG. 4B is a side view of the power supply holder 700 with the remote control unit 30 to which the power supply connection component 640 is connected, and FIG.

  In the sixth embodiment, differences from the portions described mainly in FIGS. 1 to 8 (first embodiment) will be mainly described.
