While the vehicle is running, the inside of the pipe line 10 illuminated by the light 21b is monitored by the CCD camera 21a.
When a large dust such as an empty can or empty bottle is found in the pipeline 10 while being monitored by a monitor arranged outside the pipeline 10, the cylinder 18 is extended and the suction is performed. The nozzle 17 is swung upward to the retracted position (see the solid line), the air cylinder 46 for lifting the scooping member is extended, and the scooping member 41 is lowered. Then, as the pipeline cleaning device advances, large dust 47 on the pipeline 10
Comes into the position shown by the solid line in FIG. Then, the scooping member lifting air cylinder 46 is contracted to raise the scooping member 41 to the rising position shown by the two-dot chain line in FIG. 1 to scoop up the large dust 47. Then, the large-sized waste 47 is stored in the storage unit 4
It goes into the inside of 2 and is accommodated in the accommodation part 42. in this way,
According to this embodiment, it becomes possible to collect large-sized dust that could not be collected conventionally.

Next, regarding the lowering operation of the scooping member 41 and the retracting operation of the front and rear wheels 26a, 26b, the control function of the control device 51 for preventing the scooping member 41 from being damaged will be described with reference to FIG.

As described above, the control device 51 is provided with the scooping member 4 only after the bulging of the front and rear wheels 26a and 26b is completed, that is, between the suction pipe 14 and the pipe line 10.
The solenoid valve 57 connected to the scooping member lifting air cylinder 46 is controlled so as to start the scooping of the scooping member 41 only after the space for descending 1 is secured. Therefore, when the front and rear wheels 26a and 26b have not been completely extended and there is not secured a space between the suction pipe 14 and the conduit 10 for the scooping member 41 to descend, the scooping member Since 41 does not descend, it is possible to prevent the scooping member 41 from being pressed against the conduit 10 and being damaged. The control device 51 and the solenoid valve 57 constitute a scooping member control means.

On the other hand, the wheel operation block of the control device 51 determines in step S11 whether or not the wheel storage command switch is turned on. When it is determined that the wheel storage command switch is turned on, the process proceeds to step S12, When it is determined that the wheel storage command switch is not turned on, step S
Return to 11.

In step S12, it is judged whether or not the picking member rising completion signal output from the above-mentioned picking member operation block is detected. When it is judged that the picking member rising completion signal is detected, the process proceeds to step S13, and the picking member is picked up. When it is determined that the member rising completion signal is not detected, the process returns to step S11.

The scooping member lifting completion signal is sent from the scooping member operation block 3 seconds after the scooping member lifting command switch 54 of the control device 51 is pressed, that is, after the scooping member 41 is completely lifted. It is designed to be output to the wheel operation block. In step S13, the control device 51 controls the solenoid valve 56 to start contracting the wheel overhang storage air cylinder 37 and start storing the front wheel 26a and the rear wheel 26b.

Next, in step S14, the output of the wheel bulging completion signal is stopped.

As described above, the control device 51 is arranged so that the above-mentioned front and rear ends only when the lifting of the scooping member 41 is completed.
The solenoid valve 56 connected to the wheel storage air cylinder 37 is controlled so as to start storing the rear wheels 26a and 26b. Therefore, when the lifting of the scooping member 41 is not completed, the front and rear wheels 26a and 26b are not stored, so that the scooping member 41 can be prevented from being pressed against the conduit 10 and damaged. The control device 51 and the solenoid valve 56 constitute wheel control means.
