  Here, the basic operation of the agricultural machine 1 will be described with reference to FIG. 4. When the power on / off button 42 of the remote control operation unit 41 is turned on by a push operation (step 1), the power is turned on as a manual mode. The power-on display lamp 61 is turned on (step 2). In this manual mode, the operating parts 4, 13, 27 and 29 are operated corresponding to the pressing operation only while the operating button is being pressed. When the finger is released from the activation button and the pushing operation of the activation button is released, the operation units 4, 13, 27, and 29 are stopped.

  When the mode switching button 55 of the remote control operation unit 41 is turned on by a push operation (step 3), the mode is switched to the automatic mode, and the automatic mode display lamp 62 is lit while the power-on display lamp 61 is lit. (Step 4). In this automatic mode, once the operation button is pushed (one push operation), it operates until the operation parts 4, 13, 27, 29 are set in advance.

  In such an automatic mode, when, for example, one arbitrary operation button is turned on by a pushing operation during the operation of the operation parts 4, 13, 27, 29 (step 5), The operation parts 4, 13, 27, 29 are stopped in an emergency based on the control of the control means 33 (step 6), and an emergency such as a danger can be avoided. In addition, when the operation parts 4, 13, 27, and 29 are emergency stopped, the automatic mode is automatically switched to the manual mode.

  Next, with reference to FIG. 5, the closing operation | movement of the action | operation parts 4 and 29 of the agricultural working machine 1 is demonstrated concretely.

  After the power on / off button 42 is turned on (step 11), when the mode switching button 55 is turned on (step 12), the automatic mode is set (step 13).

  In the automatic mode, when the left and right folding working units 4 are simultaneously closed (step 14), the close button 52 is turned on by a push operation by one push (step 15). When the close button 52 is turned on, normally, the left and right extension rakes 29 are closed and the folding operation is not performed, and then the left and right hydraulic cylinders 5 are contracted to simultaneously close and fold the left and right folding working units 4. A state is reached (step 16). That is, when the close button 52 is pressed once, the left and right extension rakes 29 are rotated until they are in a non-folding state, and then are rotated until the folding work unit 4 is in a folded state.

  When only the left folding work unit 4 is closed, the left selection button 53 and the close button 52 are simultaneously turned on by a push operation by one push (step 17). When the left selection button 53 and the close button 52 are turned on, normally, the left extension rake 29 is closed and the folding operation is not performed. Thereafter, the left hydraulic cylinder 5 is contracted, so that only the left folding work unit 4 is operated. Is closed and folded (step 18).

  When only the right folding work unit 4 is closed, the right selection button 54 and the close button 52 are simultaneously turned on by a push operation by one push (step 19). When the right selection button 54 and the close button 52 are turned on, normally, the right extension rake 29 closes and the folding non-operating state occurs, and then the right hydraulic cylinder 5 contracts, so that only the right folding working unit 4 Is closed and folded (step 20).

  In any of the steps 16, 18 and 20, the extension rake 29 or the folding working unit 4 is in the middle of the closing operation, and one arbitrary operation button among the plurality of operation buttons, for example, When the close button 52 is turned on by a push operation by one push (step 21), the extension rake 29 or the folding work unit 4 during the closing operation is stopped in an emergency (step 22), and an emergency such as a danger occurs. It can be avoided (step 23). In addition, after the extension rake 29 or the folding work unit 4 is stopped in an emergency, the automatic mode is automatically switched to the manual mode even if the mode switching button 55 is not operated.

  In addition, after the closing operation of the extension rake 29 is finished, the center earthing lock means 13 and the side earthing lock means 27 may be operated before the folding work unit 4 starts the closing action.

  On the other hand, in the manual mode (step 24), for example, when the left selection button 53 and the close button 52 are simultaneously turned on by a push operation by one push (step 25), both the buttons 52 and 53 are pushed. Only during that time, the left hydraulic cylinder 5 contracts, and the left folding working unit 4 performs the closing operation (step 26). For example, when the left extension rake closing button 44 is turned on by a push operation by one push (step 27), the left extension rake 29 performs a closing operation only while the button 44 is being pushed (step 27). 28). Further, for example, when the right extension rake closing button 46 is turned on by a push operation by one push (step 29), the right extension rake 29 performs a closing operation only while the button 46 is being pushed (step 29). 30). For example, when the right selection button 54 and the close button 52 are simultaneously turned on by a push operation by one push (step 31), the right hydraulic cylinder 5 is contracted only while both the buttons 52 and 54 are being pushed. As a result, the right folding work unit 4 performs the closing operation (step 32).

  In any of steps 26, 28, 30 and 32, if the pushing operation is released by releasing the finger (step 33), the extension rake 29 or the folding work unit 4 during the closing operation is emergency stopped. However, an emergency such as danger can be avoided (step 35). In the manual mode, an emergency does not occur, and if the push operation is performed for a predetermined time, the closing operation of the extension rake 29 and the folding work unit 4 is completed (step 36).

  As described above, according to the agricultural machine 1, the remote control operation unit 41 includes the mode switching button 55 that is pushed when switching between the manual mode and the automatic mode. Therefore, a wide range of users can use the same remote control operation unit 41, and when the operation button is pushed during the operation of the operation units 4, 13, 27, 29 in the automatic mode, the operation unit 4, Since 13, 27 and 29 are in an emergency stop, the safety is excellent.

  In addition, when the operating parts 4, 13, 27, 29 are in an emergency stop, the automatic mode is automatically switched to the manual mode, so that the operation of the operating parts 4, 13, 27, 29 after the emergency stop may be confused. Absent.

  In addition, regarding the safe operation unit, for example, the extension rake 29, in the manual mode, even if the pushing operation is canceled halfway, the extension rake 29 may be operated until the preset rake 29 is set in advance. .

  Moreover, it is not limited to the folding type scraping device (agricultural working machine) provided with the folding working unit (actuating unit) 4, for example, a working unit that performs embankment / spreading that moves between the forward working position and the backward working position. The present invention can also be applied to a return-type coater provided.

  Furthermore, the drive source for rotating the folding working unit 4 is not limited to the hydraulic cylinder 5, but may be an electric motor or the like.

  Further, even when the power on / off button 42 or the mode switching button 55 is pushed during the operation of the operation unit in the automatic mode, the operation unit may be brought to an emergency stop.

  Further, when the remote control unit 41 has only the power-on display lamp 61, the power-on display lamp 61 may be turned on in the manual mode, and the power-on display lamp 61 may blink in the automatic mode.
