【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

First, in describing the dust suction truck of the present invention, the configuration of the entire dust suction / transport system that suctions and transports dust by the dust suction truck will be described.

FIG. 1 is a configuration diagram showing an outline of a dust suction / transport system.

In FIG. 1, reference numeral 1 denotes a garbage storage container installed on a basement floor of an apartment or the like. The lower end of the chute 2 is connected to the upper portion of the dust storage container 1, and one end of the connecting pipe 3 is connected to the lower portion of the dust storage container 1. The other end of the connecting pipe 3 is extended to a docking station 5 installed at an appropriate place on the ground, and is detachably attached to the suction pipe 30 provided in the dust storage tank 20 of the dust suction truck C by an appropriate coupling. Has been done.

In the figure, reference numeral V1 is an opening / closing valve provided at the lower end of the chute 2, V2 is an opening / closing valve provided at one end of the connecting pipe 3, and V3 introduces outside air into the waste container 1. An on-off valve provided in the inlet pipe 4.

As shown in FIG. 2, the dust suction car C is equipped with a suction device 10 and a dust storage tank 20 for storing the dust sucked by the suction device 10.

The suction device 10 has a suction passage 11 whose one end is connected to the dust storage tank 20 and whose other end is open to the atmosphere, a water tank grabber 12 provided in the suction passage 11, and an atmosphere larger than the water tank grab 12. A blower 13 provided in the suction passage 11 on the opening side, a silencer 15 provided in the suction passage 11 on the atmosphere opening side of the blower 13, and a suction passage 11 between the water tank rubber 12 and the blower 13 And a pressure sensor 16 for detecting a negative pressure value by the blower 13.

Therefore, by operating the blower 13, the dust storage tank 20 and the dust storage container 1 connected to the dust storage tank 20 via the suction pipe 30, the docking station 5, and the connection pipe 3 are subjected to negative pressure. Will be changed.

The suction pipe 30 has a base end portion connected to an inlet 25 formed in the front surface and the upper surface of the dust storage tank 20, and a swirl pipe 31 rotatably provided around a vertical axis. A flexible tube 32 connected to the swivel tube 31, a tilting tube 33 connected to the flexible tube 32 and tiltable up and down, and a telescopic tube which is connected to the tilting tube 33 and is horizontally expandable and contractable. 35, a flexible tube 36 connected to the expandable tube 35, and a tip portion 37 connected to the flexible tube 36.

The dust storage tank 20 is configured such that a rear end opening of the dust storage tank 20 can be opened and closed by an opening / closing door 21 that opens rearward around an upper edge. The opening / closing door 21 is provided with a support member 21a for supporting the front end portion 37 of the suction tube 30.

A discharge plate 22 is provided inside the dust container 20 so as to be slidable in the front-rear direction.

The discharge plate 22 has two points, a front dust suction position A1 and a two-point dust suction position A1 shown by a solid line in FIG. 2 by a telescopic cylinder 23 connected between the front surface of the discharge plate 22 and the front wall 20a of the dust storage tank 20. It can slide to and from the rear discharge position A2 shown by the chain line.

The discharge plate 22 is a shoe portion for guiding the dust sucked into the dust storage tank 20 through the base end portion of the suction pipe 30 and the inlet 25 to the rear side together with the inertial force due to the suction. 22a and a dust compressing portion 22b. At the time of starting dust suction, the chute portion 22a is continuous with the base end of the suction pipe 30 through the inlet 25, that is, the dust suction position A1. By disposing the discharge plate 22 in the above, the dust sucked through the suction pipe 30 is blown to the rear end portion of the dust storage tank 20 by the chute portion 22a.

On the other hand, as shown in FIGS. 2 and 3, a base end portion of the scraping plate 26 is rotatably supported above the rear portion of the dust storage tank 20. The base end of the scraping plate 26 is connected to the rod end of the telescopic cylinder 27 via the arm 28, and the telescopic operation of the telescopic cylinder 27 causes the horizontal position to be horizontally arranged along the upper surface of the dust storage tank 20. And a discharge position where the discharge plate 22 is disposed at the discharge position A2, and the discharge plate 22 rotates to the lower portion of the chute portion 22a.

Therefore, when the discharge plate 22 is arranged at the discharge position A2, the scraping plate 26 is rotated from the horizontal position to the scraping position to scrape out the dust remaining on the chute portion 22a of the discharge plate 22 rearward. You can

When performing the dust suction work with the dust suction wheel C configured as described above, the dust suction wheel C is brought closer to the docking station 5 and stopped, and then the swivel pipe 31 is swung. Then, the entire suction pipe 30 is turned to the side of the vehicle, and the tip end 37 of the suction pipe 30 is connected to the docking station 5 by tilting the tilting pipe 33, expanding and contracting the expansion pipe 35, and the like. The waste container 20 and the waste container 1 are communicated with each other via the connection pipe 3 and the suction pipe 30. Then, after closing the opening / closing valves V1 and V3 and opening the opening / closing valve V2, the blower 13 is operated to make the dust storage container 1, the connection pipe 3, the suction pipe 30 and the dust storage tank 20 negative pressure, and thereafter. By opening the open / close valve V3 and introducing the outside air into the dust storage container 1 from the introduction pipe 4, the dust in the dust storage container 1 is sucked and transported to the dust storage tank 20.

Next, the operation of collecting and discharging dust to and from the dust storage tank 20 when dust is sucked by the dust suction car C described above will be described.

First, when dust suction is started, the discharge plate 22 is arranged at the dust suction position A1 where the chute portion 22a is continuous with the base end portion of the suction pipe 30 through the introduction port 25, and the blower 13 is placed in this state. Activate it to suck dust. As a result, the dust sucked into the waste storage tank 20 through the suction pipe 30 is blown to the rear end portion of the dust storage tank 20 by the action of the chute portion 22a of the discharge plate 22 and the inertial force of the suction. The garbage collection tank 20 is gradually deposited from the rear end thereof.

Then, when the dust storage tank 20 is apparently filled with dust, the discharge plate 22 is appropriately reciprocally slid back and forth between the dust suction position A1 and a position slid rearward by a suitable distance to remove dust. Is pushed into the rear portion of the dust storage tank 20 and compressed to create a space in the front portion of the dust storage tank 20.

Here, when the discharge plate 22 is appropriately reciprocally slid between the dust suction position A1 and the position slid rearward from the dust suction position A1 as described above, it is necessary to stop the dust suction operation. is there. The reason for this is that during the dust suction operation, when the discharge plate 22 is slid rearward of the base end portion of the suction pipe 30 in order to compress the dust, the dust sucked through the suction pipe 30 is discharged. Because it will invade in front of.

Further, as means for detecting that the dust is full, judgment is made based on the negative pressure value by the pressure sensor 16 provided in the suction device 10. That is, when the dust is full, the same closed state as the closed state in the connection pipe 3 and the suction pipe 30 is brought about, so that the negative pressure value detected by the pressure sensor 16 increases. Therefore, when the negative pressure value of the pressure sensor 16 exceeds a preset negative pressure value, it is determined that the dust is full. The means for detecting that the dust is full is not limited to the pressure sensor 16.

In this way, the operation of compressing and storing the dust in the dust storage tank 20 is repeated a proper number of times, whereby the dust is efficiently compressed and the dust is stored until the dust storage tank 20 becomes full.

The movement control of the discharge plate 22 described above is performed by a control device (not shown) based on a detection signal from the pressure sensor 16 or the like.

When the dust in the dust storage tank 20 is to be discharged, after the opening / closing door 21 is opened upward, the discharge plate 22 is slid backward to the discharge position A2 at the rear end of the dust storage tank 20. By doing so, the dust in the dust storage tank 20 is discharged.

At the time of discharging the dust, the scraping plate 26 is rotated downward so that the dust collected in the shoot portion 22a is scraped backward and discharged from the rear end opening.

The dust suction car C of the present invention is not limited to sucking the dust stored in the dust storage container 1, but can also directly suck the dust from the tip of the suction pipe 30, for example.
