Moreover, the opening and closing lid and the rotating telescopic cylinder of the opening and closing lid are separated and the tightening device is operated to remove the dust disposal frame. When flipped,
Since the rotary telescopic cylinder is changed from two-point support to one-point support, the rotary telescopic cylinder rotates about the pivot center of the cylinder, and the position where the open / close lid is connected and locked is lost. Then, when connecting to the opening / closing lid again, there is a problem that it is necessary to carry out connection position adjustment and then connection, which makes the operation difficult.

In the reversing mechanism of the dust pushing device of the dust collecting vehicle, since the pivot portion of the dust loading device is located above the dust collecting vehicle, when the dust pushing device is inverted with this pivot portion as a fulcrum,
When the dust pushing device is lifted to a high position and the container type dust container is lowered in this state, the stability of the entire vehicle deteriorates, and when the container type dust container is attached or detached, the pillars become an obstacle. There is a problem in that the workability of loading and unloading is poor, and the outer plate is damaged due to the contact with the container-type dust container, and the appearance is impaired.

There is. That is, the dust pushing device 10 pivotally supported by the frame 3 of the dust collecting vehicle 60 via the shaft 61 has the hydraulic cylinder 63.
By the expansion and contraction operation of the
Invert between the positions indicated by the dashed lines.

The dust-pushing device 10 pivotally supported on the pedestal 3 by the shaft 61 is compressed by the hydraulic cylinder 63,
It is inverted in the clockwise direction and placed at the position indicated by the chain double-dashed line. This disengages the dust pushing device 10 and the dust storage box 4, and the upper part of the dust pushing device 10 is largely opened from the dust storage box 4. It Therefore, when the dust container 4 is attached to or detached from the gantry 3, the dust pushing device 10 does not become an obstacle.

To re-engage the dust pushing device 10 and the dust storage box 4, the hydraulic cylinder 63 is extended and the dust pushing device 10 is turned counterclockwise.

In the dust collecting vehicle 60 shown in FIG. 14, the dust pushing device 10 is pivoted downward to the rear at a position where the pivot support of the dust pushing device 10 to the pedestal 3 is low, so that the center of gravity of the dust pushing device 10 is lowered and the dust storage box 4 is lowered. The stability of the vehicle in the closed state is good, the load applied to the base of the column can be reduced, the structure on the pedestal can be simplified and the weight can be reduced, and when the dust pushing device 10 is inverted, the dust pushing force can be reduced. When the device 10 is inspected and repaired, since the hydraulic cylinder is at the most compressed position, even if oil leaks to the hydraulic cylinder, the dust pushing device does not drop, and safety during the work is secured. . Moreover, when the dust pushing device connected to the dust storing port is separated from the dust storing port, the upper side of the dust pushing device has a large opening, which facilitates the work of loading and unloading the dust storing box.
