BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust suction truck for sucking and collecting dust stored in a dust container, for example.

[0002]

2. Description of the Related Art Conventionally, a dust suction wheel of this type is equipped with a suction device and a dust storage tank for storing the dust sucked by the suction device, and is formed on the upper surface and front end of the dust storage tank. The base end of the suction pipe is connected to the inlet, and the dust is stored in the dust storage tank from the suction pipe through the inlet by suction by the suction device.

A dust compressing / discharging plate is provided in the dust storage tank so as to be slidable back and forth. At the upper part of the dust compressing / discharging plate, there is formed a chute part for guiding the dust sucked into the dust storage tank through the base end part of the suction pipe to the rear side together with the inertia force due to the suction. At this time, by disposing the dust compressing / discharging plate at a position where the chute portion faces the base end portion of the suction pipe, the dust sucked through the suction pipe is blown to the rear end portion of the dust storage tank by the chute portion. Was there.

If the dust in the dust storage tank is full or if the dust is accumulated to some extent, the dust compression / discharge plate is slid back and forth to compress the dust in the dust storage tank. Further, when discharging dust, the dust compressing / discharging plate is slid to the rear of the dust storage tank and discharged from the rear end of the dust storage tank.

[0005]

However, in the above-mentioned conventional apparatus, if the length of the dust storage tank is increased so that a large amount of dust can be stored, the distance from the front end to the rear end of the dust storage tank becomes long. Therefore, even if the chute is used, it is impossible to fly the dust from the front end portion to the rear end portion of the dust storage tank, and as a result, the dust is accumulated in the middle portion of the dust storage tank, which reduces the filling efficiency. It was necessary to frequently perform the compression of the dust by the invited dust compaction and discharge plate.

[0006]

The garbage suction truck of the present invention comprises:
A garbage storage tank mounted on the vehicle frame and having an opening / closing door at the rear, a suction pipe having a base end portion continuously connected to substantially the center of the upper surface of the garbage storage tank, and a suction device for making the waste storage tank negative pressure, It is slidably provided from the foremost position to the rearmost position in the dust storage tank, and is placed immediately before the base end of the suction pipe when dust suction starts, so that the space behind it is full. When the dust is compressed, it is arranged at the foremost position, and at the time of dust compression, the dust compression and discharge plate is provided that slides between the foremost position and an appropriate intermediate position of the dust storage tank.

[0007]

First, when the dust suction is started, the dust compressing / discharging plate is arranged immediately in front of the base end of the suction pipe, and in this state, the dust is sucked by the suction device to be located behind the dust compressing / discharging plate. Collect the garbage in the second half of the tank. And
When the latter half of the dust container is filled with dust, the dust compressing / discharging plate is slid forward and disposed at the foremost position, and the dust is accommodated in the space created by the movement to the foremost position. After that, when this space is filled with dust, the dust compressing / discharging plate is appropriately reciprocally slid between the frontmost position and an appropriate middle position of the dust storage tank to remove dust accumulated in this portion. It is pushed into the second half of the storage tank and compressed together with the dust existing in the second half, thereby creating a space in the first half of the dust storage tank and storing the dust in this space.

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.
And a water task rubber 12 provided in the suction passage 11.
A blower 13 provided in the suction passage 11 on the atmosphere open side of the water task rubber 12, a silencer 15 provided in the suction passage 11 on the air open side of the blower 13, the water task rubber 12 and the blower 13. Suction passage 11 between
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 are made to have a negative pressure.

The suction tube 30 has a base end connected to the upper surface and substantially the center of the dust storage tank 20 and a swirl tube 31 rotatably provided around a vertical axis, and the swirl tube 31.
A flexible tube 32 connected to the flexible tube 32, a tilt tube 33 connected to the flexible tube 32 and vertically tiltable, and a telescopic tube 35 connected to the tilt tube 33 and capable of expanding and contracting in a horizontal direction, The flexible tube 36 is connected to the expandable tube 35, and the tip portion 37 is connected to the flexible tube 36. Reference numeral 38 is a support member for supporting the tip portion 37.

The dust storage tank 20 is constructed such that a rear end opening of the dust storage tank 20 can be freely opened and closed by an opening / closing door 21 which opens rearward around an upper edge, and a dust compressing / discharging plate 22 is slid in the front / rear direction. It is movably arranged.

The dust compressing / discharging plate 22 is shown by a chain double-dashed line in FIG. 2 by a telescopic cylinder 23 connected between the front surface of the dust compressing / discharging plate 22 and the front wall 20a of the dust container 20. It is possible to slide between the front position A1 and the rearmost position A2 shown by the one-dot chain line.

On the upper part of the dust compressing / discharging plate 22, a chute portion 22a for guiding the dust sucked into the dust storage tank 20 through the base end portion of the suction pipe 30 to the rear side together with the inertial force due to the suction. When the dust suction is started, the dust compressing / discharging plate 22 is arranged at a position A3 where the chute portion 22a faces the base end portion of the suction pipe 30, so that the dust is sucked through the suction pipe 30. The incoming dust is thrown to the rear end of the dust storage tank 20 by the chute portion 22a.

When performing the dust suction work with the dust suction wheel C thus constructed, after the dust suction wheel C is brought close to the docking station 5 and stopped,
By swiveling the swirl pipe 31, the entire suction pipe 30 is swung to the side of the vehicle, and the tip end portion 37 of the suction pipe 30 is swung by the tilting of the tilting pipe 33, the telescopic motion of the telescopic pipe 35, and the like.
Is connected to the docking station 5, so that the waste container 20 and the waste container 1 are communicated with each other via the connection pipe 3 and the suction pipe 30. And the on-off valve V1,
After closing V3 and opening the on-off valve V2, the blower 13 is operated to make the dust storage container 1, the connecting pipe 3, the suction pipe 30, and the dust storage tank 20 negative pressure, and then the on-off valve V3 is opened and introduced. By introducing the outside air into the dust storage container 1 through the 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 dust in the dust storage tank 20 when dust is sucked by the above-mentioned dust suction car C will be described.

First, at the start of dust suction, the dust compressing / discharging plate 22 is arranged at a position A3 where the chute portion 22a of the dust compressing / discharging plate 22 faces the base end of the suction tube 30, and in this state. The blower 13 is operated to suck dust. As a result, the garbage storage tank 20 is transferred through the suction pipe 30
The dust sucked therein is blown to the rear end of the dust storage tank 20 by the action of the chute portion 22a of the dust compression / discharge plate 22 and the inertial force due to the suction, and the dust storage tank 20
It is gradually deposited from the rear end of the.

When the space behind the dust compressing / discharging plate 22 is filled with dust, the dust compressing / discharging plate 22 is slid forward and placed at the foremost position A1, and dust is continuously sucked. ..

Here, the means for detecting that the dust is full is determined based on the negative pressure value by the pressure sensor 16 provided in the suction device 10. In other words, when the dust is full, the closed state similar to the closed state in the connection pipe 3 and the suction pipe 30 occurs, so that the pressure sensor 1
The negative pressure value detected in 6 increases. Therefore, the pressure sensor 1
When the negative pressure value of 6 exceeds a preset negative pressure value, it is determined that the dust is full, and the dust compression / discharge plate 22 may be arranged at the frontmost position A1. The means for detecting that the dust is full is not limited to the pressure sensor 16.

By disposing the dust compressing / discharging plate 22 at the frontmost position A1 as described above, dust is accumulated in the space portion generated by the movement of the dust compressing / discharging plate 22 to the frontmost position A1.

Next, when this space is filled with dust,
Move the dust compressing and discharging plate 22 from the frontmost position A1 to the position A
3, the dust accumulated in this portion is pushed into the latter half of the dust storage tank 20 and is compressed together with the dust present in the latter half, that is, the first half of the dust storage tank 20, that is, the suction pipe. A space is made forward from the base end of 30.
As a result, the dust sucked into the dust storage tank 20 via the suction pipe 30 is accumulated in the first half of the dust storage tank 20. That is, the position A3 where the chute portion 22a of the dust compressing / discharging plate 22 faces the base end portion of the suction pipe 30 is the maximum compression position of the dust compressing / discharging plate 22.

It is to be noted that the pressure sensor 16 described above detects that the front half of the dust storage tank 20 is full of dust.

By repeating the operation of compressing and storing the dust in the latter half portion of the dust storage tank 20 a proper number of times,
The dust is efficiently compressed and stored in the dust storage tank 20. Then, if it is necessary when dust cannot be compressed and stored in the latter half of the dust storage tank 20 by repeatedly compressing and storing the dust storage tank 20, the dust compression / discharge plate 22 is disposed at the forefront position A1. The garbage is stored until the first half of the storage tank 20 is full.

Here, in this example, the dust compressing and discharging plate 22 is used.
The chute portion 22a is moved rearward to a position A3 facing the base end of the suction tube 30 to compress dust, and the dust is compressed behind the position A3, that is, from the base end of the suction tube 30 to the rear. Since it is not moved, the dust in the dust storage tank 20 can be compressed while continuing the dust suction operation.

The movement control of the dust compressing / discharging 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, the opening / closing door 21 is opened upward, and the dust compression / discharge plate 22 is moved backward to the rearmost position A2 at the rear end of the dust storage tank 20. By sliding it to the garbage storage tank 2
Eject the dust inside 0.

In this example, the maximum compression position of the dust compression / discharge plate 22 is set to the chute portion 22 of the dust compression / discharge plate 22.
Although a is located at the position A3 facing the base end of the suction pipe 30, the maximum compression position by the dust compressing / discharging plate 22 is at position A3.
It may be behind 3. In this case, although the dust compression ratio can be increased, it is necessary to stop the dust suction operation when moving the dust compressing / discharging plate 22 rearward of the position A3. The reason for this is that when the dust compressing / discharging plate 22 is slid rearward of the base end portion of the suction pipe 30 in order to compress the dust during the dust suction operation, the suction pipe 30
This is because the dust that is sucked through passes through the front of the dust compression and discharge plate 22.

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

[0034]

As described above, according to the present invention, it is possible to efficiently store dust in this dust storage tank even if the length of the dust storage tank is increased so as to store a large amount of dust.
