BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to a vacuum working vehicle capable of efficiently sucking an object to be sucked such as sludge and dirt.

[0002]

2. Description of the Related Art For example, sludge and filth accumulate on the bottom of sewers, gutters, sewage tanks, and the like. These objects to be sucked such as sludge and filth are sucked by a vacuum working vehicle having a well-known configuration. Has been processed later. Conventionally, the vacuum hose of such a vacuum working vehicle has been manually moved.However, as the vacuum working vehicle has become larger, the diameter of the vacuum hose has been increased. It was difficult to move the hose manually.

For this reason, in recent years, as shown in FIG. 3 of a configuration explanatory view, for example, a bendable work arm 52 composed of a boom 52a and an arm 52b supported by a crawler type traveling vehicle 51 so as to be able to move up and down. A vacuum work vehicle having a free-end vacuum hose 53 along its side is used. Therefore, the vacuum hose 53 is moved to a predetermined position by raising and lowering and bending the working arm 52, and suction objects such as sludge and dirt are sucked from the suction port 53a at the tip thereof.

[0004]

However, a vacuum working vehicle in which a vacuum hose is provided along the side of a working arm of a traveling vehicle is only a primary one, and the tip of the vacuum hose is free. Since the arm itself is in the way, it is difficult for the driver or the like to adjust the suction port to the position of the object to be suctioned.

Accordingly, an object of the present invention is to provide a vacuum working vehicle capable of reliably sucking an object to be sucked by positioning a suction port at a suction position of the object to be sucked.

[0006]

According to the present invention, if the working arm has a function as a vacuum tube, the suction port at the tip thereof can be adjusted to the position of the object to be sucked. It is thought that the working arm itself does not get in the way as in.

Therefore, the main feature of the vacuum working vehicle according to the present invention is that it has a suction port 7a at its tip for sucking an object to be sucked, and a bending portion through a flexible hose 8 at a bending portion. The free vacuum tube 5 is raised and lowered by the traveling vehicle 1 and the vertical axis is used as a fulcrum.
Ing freely supported, the distal end of the vacuum tube 5, as well as attaching a pivotable raking allowed ingredients 9 raking causes the object to be sucked object to the suction port side, the proximal side, to suck the object to be sucked object Suction source flexible hose 10 communicating with the suction device
Is connected.

[0008]

According to the vacuum work vehicle according to the present invention, the vacuum tube 5, supported Rutotomoni, the vertical axis is freely bent because of through the flexible hose 8 in the bent portion
By swinging as a point , the suction port 7a is moved to a target position, and the scraping tool 9 is swung, so that an object to be suctioned such as sludge or dirt can be scraped and sucked in the direction of the suction port 7a. In addition, the vacuum tube 5 does not extend along the side of the working arm as in a conventional vacuum car, and the working arm itself is a vacuum tube 5. Therefore, when moving the vacuum tube 5,
Is not in the way.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vacuum working vehicle according to an embodiment of the present invention will be described below with reference to FIG. 1 of a side view thereof and FIG. 2 of a plan view thereof. The traveling vehicle 1 includes a crawler-type traveling trolley 2 and a driver's seat 3 having a driving source mounted thereon, and has the same configuration as a so-called well-known mini excavator body. Things. The traveling vehicle 1 having the above configuration
At the front of the driver's seat 3, a vacuum tube 5, which will be described later, is pivotally attached to a swing frame 4 supported by a vertical axis P _{1 so as} to swing freely via a horizontal base axis P _2. have been, the vacuum tube 5 is configured to be undulating derricking cylinder C _1.

The vacuum tube 5 is mainly composed of
A first vacuum tube 6 and a pair of horizontal tube connecting shafts P ₃ provided at the distal end of the first vacuum tube 6 so as to be swingable,
A second vacuum tube 7 communicates between a distal end portion and a proximal end portion of the first vacuum tube 6 via a flexible hose 8, and the second vacuum tube 7 is connected to the first vacuum tube 6. It adapted to be swung by the swinging cylinder C ₂ is pivotally straddling and.

More specifically, the first vacuum tube 6
Fig. 2 shows that a steel pipe is bent into a "U" shape and
As shown in, have bent to the proximal end side to avoid the traveling vehicle 1, in this position, base bracket 6a which is pivotally attached to the proximal shaft P ₂ is attached, on both sides of the tip second tip bracket 6b are projected to support the vacuum tube 7 via a pair of the tube connecting shaft P _3.

The second vacuum tube 7 has a suction port 7a at its tip for sucking sludge and dirt. And that the distal end portion is pivotally attached swingably by ingredients 9 a horizontal take-shifting tool support shaft P ₄ were raking, tool 9 so this raking, this and straddling the second vacuum tube 7 It is configured to be swung by the take shifting device actuating cylinder C ₃ to be pivoted.

That is, as can be understood from the above description, the vacuum tube 5 of the vacuum working vehicle in this embodiment is configured as if it were a working arm of a conventional hydraulic shovel. On the other hand, a suction source flexible hose 10 is connected to a base end of the first vacuum tube 6, and a distal end of the suction source flexible hose 10 communicates with a suction device (not shown). In addition, what is provided in front of the traveling vehicle 2 is a discharge plate 2.
This is a, which functions as an outrigger for preventing the traveling vehicle 1 from overturning.

The operation of the vacuum working vehicle having the above-described structure will be described below. The vacuum tube 5 supported by the traveling vehicle 1 so as to be able to move up and down is provided with a flexible hose 8 at a bending portion. It is bent freely by the operation of the C _2, and by undulations by actuation of derricking cylinder C _1, moves the suction port 7a of the tip in a position of interest.

Next, by operating the raking device operating cylinder C ₃ to swing the raking device 9, the suction port 7 a
When the suction device is operated by squeezing an object to be sucked such as sludge or filth in the direction of the arrow, the object to be sucked passes through the second vacuum tube 7, the flexible hose 8, the first vacuum tube 6, and the suction source flexible hose 10. Suction by the suction device. Of course, during the suction of the object to be suctioned, the scraper 9 is operated as needed.

In the work of sucking an object to be sucked,
Unlike a conventional vacuum work vehicle, a vacuum hose is not provided along the side of the work arm, and the work arm itself constitutes the vacuum tube 5, so that the vacuum tube 5 is obstructed when moving. In addition to being able to easily move the suction port 7a to the position of the object to be suctioned, the object to be suctioned is scraped toward the suction port 7a by the scraper 9, so that the object to be suctioned is Aspiration can be performed with high efficiency.

In the above, the case where the traveling vehicle 1 has the crawler-type traveling vehicle 2 has been described as an example. However, it is not particularly necessary that the traveling vehicle 2 is a crawler-type traveling vehicle. The technical idea according to the present invention can also be applied to a traveling vehicle having.

[0018]

As described above, according to the vacuum working vehicle of the present invention, the suction port of the vacuum tube is freely moved to the target position, and the scraper is swung to the direction of the suction port. The vacuum tube is not along the side of the working arm, unlike a conventional vacuum car, and the working arm itself is attached to the vacuum tube. Since the vacuum tube does not hinder the moving operation, there is a great effect related to the improvement of the efficiency of the suction operation in that the object to be suctioned can be sucked with high efficiency.
