Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an excavator seat device for preventing scattering of mud and muddy water from an excavation bucket when excavating with an excavator.

[0002] For example, when excavating by a bucket type underground continuous wall method, an operation is performed in which mud and mud generated by excavation are lifted by an excavating bucket of an excavator and carried out to a carrier vehicle or the like. At that time, mud and muddy water may be scattered from the excavation bucket. Therefore, conventionally, an enclosure was constructed around the excavation site with a universal plate or sheet, and the enclosure was used to prevent the scattering of mud and muddy water.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional configuration has the following problems. In other words, since the excavation site moves with the progress of construction work, even if it is necessary to move around the mud and muddy water splash prevention enclosures each time, it is necessary to move through repeated removal and assembly. There was a problem of being there. In addition, although it is possible to prevent the particles from scattering inside the site outside the enclosure, it is not possible to prevent the particles from scattering inside the enclosure, and there is a problem that the work site becomes dirty. Furthermore, in bad weather, such as in strong winds, it was necessary to remove or reinforce the enclosure.

The present invention has been made on the basis of such a point, and its intended purpose is to easily follow the movement of the excavation site, and also to make mud and mud on-site. Another object of the present invention is to provide a seat device for an excavation bucket, which can prevent the scattering of water and can be easily handled in bad weather such as strong wind.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a seat device for an excavation bucket according to the present invention is a frame body detachably attached to the excavator body of an excavator body including an excavator body and an excavation bucket attached to a tip of the excavator body. And a sheet that is attached to the frame and covers at least the excavator of the excavator and the excavator bucket, and expands and contracts in a bellows shape according to the operation of the excavator to provide the excavator and the excavator thereof. It is characterized in that it acts so as to cover at least the excavation bucket of the bucket.

[0006]

[Action]

 The excavator seat device of the present invention is detachably attached to the excavator main body and is configured to expand and contract as the excavator moves. That is, the sheet attached to the frame is stretched or folded. Then, at least the excavation bucket of the excavator main body and the bucket is surrounded to prevent scattering of mud and muddy water from the excavation bucket. Further, when the excavation site moves, the excavator seat device automatically moves as the excavator moves.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The excavation bucket seat device according to the present embodiment is detachably attached to the excavator body of the excavator. That is, the excavator seat device 5 is detachably attached to the excavator main body 1 so as to cover the excavator main body 1 and the excavation bucket 3 attached to the tip end thereof.

The excavator seat device 5 has the following configuration. First, the main holding frame 7 is at the uppermost position, the weight frame 9 is at the lowermost position, and a plurality of holding frames 11 are arranged between the main holding frame 7 and the weight frame 9. The main holding frame 7, the weight frame 9, and the plurality of holding frames 11 form a frame body. The seat 13 is attached while being supported by the main holding frame 7, the weight frame 9, and the holding frame 11. The sheet 13 can be expanded and contracted like a bellows. Then, it is removably attached to the excavator 1 via an attachment member 15 attached to the main holding frame 7.

A guide wall 17 is installed at the excavation site 16, and the excavator main body 1 and the excavation bucket 3 are inserted into / extracted from the excavation site through the opening 19 of the guide wall 17. become. The weight frame 9 is formed to be slightly larger than the opening 19 of the guide wall 17, and is mounted on the guide wall 17 when the excavator body 1 and the excavation bucket 3 are inserted into the excavation site. It is configured to be placed.

Based on the above configuration, the operation will be described with reference to FIGS. 4 to 7. First, as shown in FIG. 4, when the excavator main body 1 and the excavation bucket 3 are suspended above the ground, the excavator seat device 5 extends the seat 13 by its own weight. 1 and the excavation bucket 3 are covered.

Next, when the excavator main body 1 and the excavation bucket 3 are inserted into the excavation site 16 through the opening 19 of the guide wall 17 for excavation, as shown in FIG. The sheet device 5 is left on the guide wall 17. That is, since the weight frame 9 is formed slightly larger than the opening 19 of the guide wall 17, the weight frame 9 comes into contact with the edge of the guide wall 17 and the sheet 13 is thereby folded. .

Next, when excavation is performed and the excavator body 1 and the excavation bucket 3 are pulled up from the excavation site 16, the sheet 13 is gradually extended as shown in FIG. The machine body 1 and the excavation bucket 3 are covered. Then, when the excavator main body 1 and the excavation bucket 3 are completely pulled up from the excavation site 16, a state as shown in FIG. 7 is obtained. In that state, the excavator is transported to the transport vehicle 21, and the excavation bucket 3 is opened there. The muddy water 23 is discharged into the carrier 21 to the extent that it is generated by excavation.

According to this embodiment, the following effects can be obtained. First, scattering of mud and muddy water from the excavation bucket 3 is reliably prevented by the seat 13 of the excavator seat device 5. At that time, the operation of the excavator is not hindered. Further, since the excavator seat device is mounted on the excavator body 1 side, even if the excavation site 16 moves, the excavator seat device 5 also automatically moves when the excavator body 1 moves. Since it has been moved, there is no need for complicated removal and assembly work as in the past, which greatly simplifies the work.

Further, since the excavator seat device 5 is configured so as to enclose the excavator body 1 and the excavation bucket 3 in the narrowest possible range, scattering of mud and muddy water at the excavation site 16 is also effectively prevented. To be done. Further, even if it scatters, it will fall into the excavation site 16 through the inner surface of the sheet 13, so that the contamination around the excavation site 16 can be minimized.

Further, since the excavator seat device 5 itself has a bellows shape, it can be folded and stored when not in use, and the storage space is small, and storage is easy. Also, the attachment / detachment to / from the excavator main body 1 can be easily performed via the attachment member 15.

The present invention is not limited to the above-mentioned one embodiment. For example, the seat may be sized to cover at least the digging bucket. Further, the structure of the frame body and the method of attaching and detaching it to the excavator body are not limited to those shown in the drawings.

[0017]

[Effect of device]

 The excavator seat device according to the present invention is detachably attached to the excavator body, so that even if the excavation site moves, the excavator body automatically moves when the excavator body moves. Therefore, complicated removal and assembly work as in the past is not necessary. Also, by expanding and contracting appropriately, the operation of the excavator will not be hindered.
