The end of the transport pipe 16 is extended to a docking station 30. The docking station 30 is detachably connected to a suction pipe 60 of a garbage truck C described later.

Next, a brief description will be given of a dust collection vehicle C for sucking and collecting the dust stored in the container body 10 of the dust storage container, and a dust collecting operation by the dust collection vehicle C.

The refuse collection vehicle C has a suction device 40 and a refuse storage chamber 50 for storing refuse sucked from the container body 10.

The suction device 40 is composed of a blower (not shown) or the like, and the operation of the suction device 40 reduces the pressure in the container body 10 and the dust storage chamber 50.

The garbage storage chamber 50 is provided with an opening / closing door 51 whose rear end wall is opened rearward about an upper end edge by an opening / closing cylinder (not shown), and is slidably discharged in the garbage storage chamber 50 in the front-rear direction. A plate (not shown) is provided, and the dust stored in the dust storage chamber 50 is dumped to the rear of the vehicle by sliding the discharge plate backward by the expansion and contraction movement of a discharge cylinder (not shown). .

A base end of a suction pipe 60 is connected to an upper portion of the dust storage chamber 50, and a distal end of the suction pipe 60 is hung at a rear portion of the dust storage chamber 50. The suction tube 60 has a base portion that is configured to be pivotable, a horizontal portion that is configured to be able to expand and contract, and undulate freely. These operations connect the distal portion to the docking station 30.

The refuse collection vehicle C is provided with a control device (not shown) including a microcomputer and the like. This control device and the container main body 10 side of the refuse storage container 1 are connected via a docking station 30 by a signal cable (not shown).

The control device detects signals from the above-mentioned detectors of the container body 10, a pressure detector (not shown) for detecting a negative pressure value in the container body 10 or the refuse storage chamber 50 by operating an operation device (not shown). Of the suction device 40, the input gate 12, the discharge gate 17, and the secondary valve 22 based on the
The opening and closing operation of the suction pipe 60 is controlled, and each operation of the suction pipe 60 is controlled.
