Next, FIG. 4 to FIG. 5 show the flow of operation by operating each operation switch provided in the operation device.

First, when the power is turned on, the cable docking detector 93 determines in step S1 whether or not the signal cable 90 and the signal cable 91 are in the docking state. If the signal cable 90 and the signal cable 91 are in the docking state (the cable docking detector 93 is turned on). ) To step S2, and in step S2 it is determined whether the automatic suction switch is ON or OFF. If this automatic suction switch is ON, in step S3, for example, automatic suction suction transportation of the dust in the first dust storage container Tma is performed. Perform suction operation.

Further, in the step S1, the signal cable 9
0 and the signal cable 91 are not in the docking state (the cable docking detector 93 is OFF), the operation state of each operation switch is determined in steps S4 to S12, and each operation is performed according to the operation state of each operation switch. Done.

More specifically, when the discharging switch is turned on in step S4, the discharging operation of the dust contained in the dust storing tank 40 is started in step S13, and the opening / closing door 4 is opened.
1 to open the discharge plate to the rear,
The trash housed in 0 is compressed and dumped behind the vehicle.

The storage switch is turned on in step S5.
Then, the storage operation of the suction tube 50 is started in step S14, and the suction tube 50 is automatically stored in the storage position.

At step S6, the save switch is turned on.
Then, in step S15, an automatic retract operation for retracting the suction tube 50 from the storage position to the suction work area is started.

Further, in step S7, it is judged whether the direct suction switch is ON or OFF. If the direct suction switch is ON, in step S16, the dust around the dust suction wheel C is directly sucked by the suction pipe 50. Take action.

When the lift switch is operated "up" in step S8, the lift up operation is started in step S17, the undulating pipe 53 of the suction pipe 50 is tilted upward, and the lift switch is operated "down". In step S18, the lifting operation is started, and the undulating tube 53 of the suction tube 50 is tilted downward. The operation of "up" and "down" by the lift switch is performed, for example, by a lift switch that can be tilted left and right. That is, tilting the lift switch to the right performs an "up" operation, and tilting the lift switch to the left performs a "down" operation.

In step S9, the extension switch is "extended".
Operation to start horizontal extension operation in step S19,
When the telescopic tube 55 of the suction tube 50 is extended in the horizontal direction and the telescopic switch is operated to "shrink", step S20 is performed.
Then, the horizontal contraction operation is started, and the expansion tube 55 of the suction tube 50 is contracted in the horizontal direction. "Stretch" by this telescopic switch,
Similar to the lift switch described above, the operation of "contracting" is performed by, for example, a telescopic switch that can be tilted left and right.

When the turning switch is operated to "right" in step S10, the turning right operation is started in step S21, the turning pipe 51 of the suction pipe 50 is turned to the right side of the vehicle, and the turning switch is operated to "left". Then, in step S22, the swiveling left operation is started, and the swirling pipe 51 of the suction pipe 50 is
Turn to the left side of the vehicle. The operations of "right" and "left" by the turning switch are performed by the turning switch configured to be tiltable to the left and right, for example, like the lift switch described above.

If the discharge plate switch is operated "front" or "rear" in step S11, steps S23 and S24 are performed.
At the same time, the forward / backward movement of the discharge plate 22 is started, and when the opening / closing door switch is operated to “open” and “close” in step S12, the opening / closing operation of the opening / closing door 41 is started in steps S25 and S26.

As described above, when the signal dock 90 and the signal cable 91 are in the docking state by the cable docking detector 93 in step S1, only the automatic suction operation is performed and each operation of the suction tube 50 is prohibited. The suction pipe 50 does not accidentally come off from the docking station 60 during the automatic suction operation, and the signal cables 90 and 91 connected by the connector 92 and the air hoses 80 and 81 connected by the coupling 82 are not attached to the docking station 60. It is possible to prevent damage such as cutting and prevent leakage of dust to the outside due to the suction pipe 50 being detached from the docking station 60 during dust suction transportation.

As in this example, the air hoses 80, 8
When 1 is also connected at the docking station 60, a detector for detecting whether or not the air hoses 80, 81 are in the connected state is provided, and the detector and the cable docking detector 93 form an AND circuit. Both the detector and the cable docking detector 93 are turned off.
The suction tube 50 may be operable only when the signal cable 90 and the signal cable 91 and the air hose 80 and the air hose 81 are not connected.
