Sediment, weeds, etc. are mixed and turned into mud, and this sludge not only clogs gutters and cross pipes, but also emits a bad odor, so it is necessary to collect it regularly. Conventionally, a vacuum suction vehicle shown in FIG. 3 has been used as a vehicle for collecting, transporting, and discarding the sludge. In this vacuum suction vehicle 1, a tank 2 is fixed to the rear portion of the vehicle body, and the front upper portion of the tank 2 is connected to a suction port 7 of a blower 6 via a pipe 3, a cyclone 4 and a separator 5. A lid 8 that can be opened and closed is provided at the rear of the tank 2, and a mud suction hose 9 is connected to the lid 8 side. When the sludge A in the gutter 10 is collected, the blower 6 is operated to keep the tank 2 at a negative pressure and the tip of the mud suction hose 9 is put into the gutter 10 to make the sludge A hose. It is collected in the tank 2 through the tank 9. After a predetermined amount of sludge A is stored in the tank 2, the sludge A is transported to a disposal site and the lid 8 is opened.
Sludge A is discarded by inclining the tank 2.

経済性に劣るという問題がある。In the above prior art, the sludge A is collected by inserting the tip of the mud suction hose 9 into the gutter 10. In the gutter 10, the sludge A and the wastewater B are collected. Therefore, at the time of collection, not only the sludge A but also the waste water B is collected in the tank 2 through the mud suction hose 9.
Therefore, when the collected wastewater B is discarded together with the sludge A at the disposal site, a bad smell is generated by the wastewater B, and the permeated wastewater B pollutes groundwater. Further, since the collected wastewater B is stored in the tank 2, the sludge A corresponding to the amount cannot be stored in the tank 2. As a result, the vacuum suction truck has to travel back and forth between the work site and the waste site many times,
There is a problem of poor economic efficiency.

A drainage hole is formed in the sludge container, and a drainage port connected to a tank of a vacuum suction car via a drainage channel is provided at a lower side of a cavity formed between the tank body and the sludge container, and a tip is provided. The mud suction passage having the opening is connected to the sludge container.

るものである。With the above construction, the tank body is in a negative pressure state because it communicates with the tank of the vacuum suction car through the drainage channel. When the tip of the mud suction path is put in a gutter or the like, sludge and waste water are stored in the sludge container through the mud suction path. The sewage reaches the cavity through the drain hole and is drained to the tank of the vacuum suction car through the drainage channel. The sludge from which the sewage has been separated is to be disposed of after disposal by opening the opening / closing part after transportation.

洞部21に流出させるようにしてもよい。Next, the operation of the above configuration will be described. The tank 2 of the vacuum suction car 1 and the drain port 26 of the tank body 12 are connected by a drain hose 27 in advance at the work site. In addition, a mud suction hose 29 having its tip placed in the side groove 10 is connected to the mud suction pipe 28 in advance. When the blower of the vacuum suction wheel 1 is operated, the inside of the tank 2 becomes a negative pressure, and the air inside the tank body 12 is sucked by this negative pressure, so that the inside of the tank body 12 also becomes a negative pressure. Therefore, the sludge A and the wastewater B in the gutter 10 are accommodated in the sludge container 17 through the mud suction path 31. Of the sucked sludge A and wastewater B, the wastewater B is separated from the sludge A through the drainage holes 24 formed in the side plate 19 and then flows into the cavity 21 and collects at the bottom of the tank body 12. Further, the wastewater B flows into the hollow portion 21 through the drain hole 24A formed in the side plate 19A and the rear hole 23 separated from the sludge A, and collects at the bottom of the tank body 12. The dirty water B collected at the bottom of the tank body 12 is stored in the tank 2 through the drain port 26 and the drain hose 27 due to the pressure difference. Therefore, the sludge A is the sludge container.
17 is stored in the tank 2, while the dirty water B is stored in the tank 2. When a predetermined amount of sludge A is stored in the sludge container 17 in this way, the work is interrupted, the drain hose 27 is disconnected from the tank 2 side, and the mud suction hose 28 is removed. After this sludge A
Is transported to the disposal site with the tank body 12, and the opening / closing plate
The opening 14 is opened to show the opening 13, and the tank body 12 is inclined and the sludge A is discarded. On the other hand, the dirty water B stored in the tank 2 is returned to the gutter 10 again by opening the lid 8. In addition, while sucking the sludge A, the manhole of the sludge container 17
The air in the sludge container 17 may be allowed to flow out to the cavity 21 through the manhole 32 of the sludge container 17 by horizontally rotating the lid of the container 32 and slightly opening it.

るために、廃棄時の作業性を高めることができる。As described above, in the above embodiment, the tank body 12 having the opening / closing plate 14 and capable of being sealed is fixed to the vehicle 11, and the sludge container 17 having a bottom is provided inside the tank body 14.
Is provided with a large number of drainage holes 24, 24A in the sludge storage body 17, and a vacuum type via a drainage pipe 27 on the lower side of the cavity 21 formed between the tank body 12 and the sludge storage body 17. A drainage port 26 connected to the tank 2 of the suction wheel 1 is provided, and a mud suction pipe 28 to which a mud suction hose 29 is further connected is communicated with the sludge storage body 17, and the vacuum suction wheel 1 of the vacuum suction wheel 1 is previously connected via the drain hose 27. When the tank main body 12 is communicated with the tank 2 to bring the tank main body 12 into a negative pressure state, and the tip of the mud suction hose 29 is put into the gutter 10, sludge A and waste water B are put into the sludge container via the mud suction hose 29.
Store in 17. On the other hand, the sewage B reaches the cavity 21 through the drainage holes 24, 24A, and therefore the sludge A is stored in the sludge container 17, and the sludge A is transported together with the tank body 12 and then the opening / closing plate 14 is opened. Only sludge A can be opened and discarded. Therefore, since it is possible to prevent only the sludge A in the gutter 10 from being discarded at the waste site and the waste water B at the waste site, the waste water B causes a bad odor at the waste site, and the permeated waste water B contaminates the groundwater. You can eliminate the risk of being Further, since the collected sewage B is stored in the tank 2, the sludge A corresponding to the amount can be stored in the tank main body 12, and as a result, the vehicle 11 does not go back and forth between the work place and the waste site many times. Excellent economy. Further, the bottom plate of the sludge container 17
Since 18 is provided so that the rear side becomes low and the width between the pair of left and right side plates 19 is also widened at the rear side, the sludge A always moves to the opening 13 side, and thus the tank 13 When the body 12 is tilted, the sludge A can be discharged smoothly. Further, the side plate 19A is attached to the opening / closing plate 14, and at the same time when the opening / closing plate 14 is opened, the rear part of the sludge container 17 is opened, so that the workability at the time of disposal can be improved.

Various modifications are possible, such as enabling the opening, or opening the top of the sludge container without providing the top plate. Further, a plurality of vehicle-mounted vacuum sludge separators may be arranged for one vacuum suction vehicle so that work can be performed continuously.
