As shown in FIG. 1, the dust suction wheel C is
A suction device 30 and a dust storage tank 40 that stores the dust sucked by the suction device 30 are mounted.

The suction device 30 has a suction passage 31 whose one end is connected to the dust storage tank 40 and whose other end is open to the atmosphere.
And a water task rubber 32 provided in the suction passage 31
And a blower 33 provided in the suction passage 31 on the atmosphere open side of the water task rubber 32, and a silencer 35 provided in the suction passage 31 on the atmosphere open side of the blower 33.

The blower 33 is operated in response to this engine speed by driving the engine of the dust suction truck C, and the blower 33 operates to move the inside of the dust storage container 10 through the dust transport pipe 25. It is designed to be pressured.

A pressure sensor 36 for detecting a negative pressure value of the blower 33 is provided in the suction passage 31 between the water task rubber 32 and the blower 33.

The dust storage tank 40 has a rear end wall formed on an opening / closing door 41 which opens rearward around the upper end edge thereof, and a discharge plate (not shown) slidably provided in the inside thereof in the front-rear direction. ), The waste in the waste storage tank 40 is discharged to the rear of the vehicle.

The suction pipe 50 is used as the dust container 4
At the upper part of 0, a swirl pipe 51 connected to the dust storage tank 40 and rotatably provided around a vertical axis, a flexible pipe 52 connected to the swirl pipe 51, and a flexible pipe 52 are connected. In addition, an undulating pipe 53 provided so as to be capable of undulating, an extensible pipe 55 connected to the undulated pipe 53, a flexible pipe 56 connected to the extensible pipe 55, and a tip end portion connected to the flexible pipe 56. 57. Reference numeral 58 is a support member for supporting the tip portion 57, and 59 is a support frame for supporting the undulating tube 53.

In the suction pipe 50 constructed as described above, the dust suction wheel C is brought closer to the docking station 60 and stopped when the dust is sucked and transported, and the swivel pipe 51 is swung, and the undulating pipe 53 is swung. The distal end portion 57 of the suction pipe 50 can be easily connected to the docking station 60 by the expansion and contraction of the expansion pipe 55, etc., so that the dust transport pipe 25 and the dust storage tank 40 are communicated with each other.

Further, the dust suction car C is provided with a control device (not shown).

The control device receives an operation signal from each operation switch provided in an operation device (not shown) and a detection signal from the pressure sensor 36, and the detection signal from the detector is passed through the docking station 60. It is input by a connected signal cable (not shown), and based on these operation signals and detection signals, the suction device 30 and the suction pipe 50 of the dust suction truck C are operated and controlled, and the secondary valve 16 is opened and closed. Is configured to. In addition,
The control device and the operating device may be provided on the garbage storage container 10 side.

Here, the upper part of the waste container 10 is
As shown in FIG. 2, the waste pipe 2 is connected by a communication pipe 17.
It is connected to 5. That is, the lower part of the waste container 10 is communicated with the waste transport pipe 25 through the discharge port 13, and the upper part is communicated with the waste transport pipe 25 through the communication pipe 17.

An on-off valve 20 is provided in the middle of the communication pipe 17.
Is provided. The on-off valve 20 normally holds the communication pipe 17 in a closed state by the weight of the weight 22 connected to the on-off valve 20 via a connecting member 21.

The weight 22 is constructed so as to be slidable in the direction of the arrow. By adjusting the sliding position, the force acting on the open / close valve 20 changes according to the lever principle.

An air cylinder 23 is connected to the connecting member 21, and the communicating pipe 17 is opened by extending the air cylinder 23 and lifting the weight 22 upward.

The piston chamber 23a of the air cylinder 23 is open to the atmosphere, and the rod chamber 23b is connected to the dust transport pipe 25 via the throttle valve 24.
Therefore, when the dust transport pipe 25 has a negative pressure, the rod chamber 23b also has a negative pressure via the throttle valve 24, so that the pressure difference between the rod chamber 23b and the piston chamber 23a causes the rod 23c of the air cylinder 23 to move. Works in the direction of stretching. When the force for extending the rod 23c becomes larger than the force for holding the on-off valve 20 in the closed position by the weight 22, the weight 22 is lifted up and the on-off valve 20 is opened. That is, by adjusting the slide position of the weight 22, it is possible to set the opening / closing valve 20 to open when the inside of the dust transport pipe 25 has a negative pressure below a desired pressure value.

Next, the operation of the dust suction / transport device thus constructed will be described.

The dust is stored in the dust storage container 10 by charging it through the charging port 11 of the dust storage container 10.

When the dust stored in the dust container 10 is sucked and transported as described above, first, the dust suction wheel C is moved to the docking station 60 and stopped, and the suction pipe 50 is operated. By connecting the tip portion 57 to the docking station 60 and operating the blower 33 with the secondary valve 16 open, while introducing outside air (secondary air) into the waste container 10 from the introduction pipe 15, Along with this secondary air, the dust in the dust container 10 is discharged through the discharge port 13, the dust transport pipe 25, the docking station 60,
It is suction-transported to the dust storage tank 40 via the suction pipe 50.

At the stage of normal dust suction and transportation as described above, the opening / closing valve 20 is in the closed position and holds the communication pipe 17 in a closed state.

When the dust group in the dust storage container 10 tries to pass through the discharge port 13 at the same time during the dust suction transportation, the dust is blocked in the discharge port 13,
Introducing pipe 15 provided above and adjacent to the outlet 13.
Is also blocked by the dust located above the dust that has blocked the discharge port 10, whereby the dust transport pipe 25
The inside is further negatively pressured than when carrying out normal garbage transportation. In this way, the inside of the dust transport pipe 25 is made negative pressure, and the inside of the dust transport pipe 25 is below a predetermined pressure value (for example, A shown in FIG.
When the pressure value at the point becomes −1000 mmAq or less), the check of the throttle valve 24 opens and the rod chamber 2 of the air cylinder 23
The negative pressure is applied to 3b, whereby the rod 23c of the air cylinder 23 extends against the weight of the weight 22, and the opening / closing valve 20 is opened to open the communication pipe 17.

As a result, the inside of the dust storage container 10 is made to have a negative pressure via the communication pipe 17, and due to the action of this negative pressure, the outside air is compared with the dust having the discharge port 13 blocked via the introduction pipe 15 in a stored state. The dust is introduced into the dust storage container 10 through a space between the upper flexible dusts, and is sucked from the upper part of the dust storage container 10 to the dust transport pipe 25 via the communication pipe 17.

As a result, the dust in the dust storage container 10 is sucked up in the dust storage container 10, and this action also sucks up the dust clogging the discharge port 13 to loosen the clogging. And outlet 1
When the dust clogged in 3 is loosened, the discharge port 13 is opened again, so that the dust is again sucked into the dust transport pipe 25 through the discharge port 13.

When the normal dust suction / transportation is performed in this way, the pressure value in the dust transport pipe 25 also becomes equal to or higher than the predetermined pressure value, and accordingly, the rod chamber 23 of the air cylinder 23.
The pressure value of b also increases and the rod chamber 23b and the piston chamber 23
Since the pressure difference with a becomes small, the weight of the weight 22 causes air to gradually flow into the rod chamber 23b while being throttled by the throttle valve 24.
c gradually shrinks, the on-off valve 20 closes, and the communication pipe 17 is closed.

As described above, even if dust is clogged in the discharge port 13 during dust suction and transportation, the clogging can be automatically removed to continue the dust suction operation, and the communication pipe 17 can be used as the dust transport pipe 25. It is opened by the on-off valve 20 only when the inside pressure becomes equal to or lower than the predetermined pressure value, and is closed during the normal dust suction / transportation. Therefore, there is a loss of transport energy due to the opening of the communication pipe 17 during the normal dust suction / transport. Therefore, it is possible to efficiently suck and transport dust.

In this example, one garbage storage container 10 is used.
I explained about what installed the garbage storage container 10
It is also possible to install a plurality of waste storage containers 10 at appropriate positions and connect these waste storage containers 10 to the waste transport pipe 25.

FIG. 3 shows another embodiment of the above-mentioned waste container.

In this dust storage container 10, the opening / closing valve 20 provided in the communication pipe 17 is configured to be openable / closable by the rotary solenoid 70. The dust transport pipe 25 is provided with a pressure sensor 71 for detecting the pressure inside the dust transport pipe 25. When the detected value by the pressure sensor 71 becomes equal to or lower than a predetermined pressure value as in the above embodiment. First, the rotary solenoid 70 is operated to open the on-off valve 20.

The other operations are the same as those in the above-mentioned embodiment, and the description thereof will be omitted.

If it is Aq or more, the process proceeds to step S8.

In step S8, this difference is 3000 mmAq.
If it is determined to be 3000 mmAq or more, it is recognized that a large amount of dust is present in a portion of the dust storage container 10 below the connecting portion of the introduction pipe 15b, and step S2 is performed.
Then, the operation of steps S2 to S7 described above is performed. If it is not more than 3000 mmAq, step S

If 0 mmAq or more, the process proceeds to step S12.

In step S12, this difference is 3000 mm.
If it is 3000 mmAq or more by judging whether it is Aq or more, it is recognized that a large amount of dust is present in a portion of the dust storage container 10 below the connecting portion of the introduction pipe 15c, and step S
