The locking devices 5 are sequentially connected. Suction force generating portion of the filler 9 is a compressor 2, a jetting hose 4, d
A suction pump device 5, one end of the ejection hose 4 is connected to the ejection port of the compressor 2, and the other end of the ejection hose 4 is connected to the air inlet 51 of the air suction pump device 5.
It is connected to.

<B> Suction Nozzle The suction nozzle 31 is a cylindrical body having both ends opened. One end of the suction nozzle 31 forms a connecting flange,
A plurality of holes are formed in the flange so that bolts can pass therethrough.

<C> Bellows hose The bellows hose 6 is a tubular hose having both ends opened.
Connection flanges are formed at both ends, and a plurality of holes are formed in the flanges so that bolts can pass therethrough. The bellows hose 6 has flexibility, and the bellows hose 6
You can move the suction nozzle 31 connected to the start end freely.

<D> Air Suction Pump Device The air suction pump device 5 is constituted by connecting two cylindrical members opened at both ends as shown in FIG. One cylindrical member is formed by an ejection pipe portion 56 which is a cylinder and a flange 54c at one end of the cylinder. The other cylindrical member is formed in the suction pipe portion 55 is cylindrical body and flange 54a and the flange 54b at both ends, the bellows hose to the flange 54a
The ends of the screws 6 are connected by bolts . Flange 54b, 5
4c is provided with a plurality of holes, and the suction pipe 55
Bolts are connected to the pipe 56. Suction pipe
The flange 54b side of the portion 55 has a double structure,
An annular groove 52 is formed therebetween, and the suction pipe portion 55
The provided air injection port 51 communicates with the annular groove 52. Both
An annular groove 52 communicates between the flanges 54b and 54c.
An annular air discharge port 53 is formed. Annular air
The reason why the discharge port 53 is formed is that the discharge port 53 is connected to the air injection port 51.
The air sent through the spout hose 4 passes through the annular groove 52
Air is discharged from the air discharge port 53, and the downstream side of the air discharge port 53
(In the direction of the spouting pipe section 56)
To generate air flow, and suction by the atmospheric pressure upstream of the air discharge port.
This is to induce attractive force .

<E> Bag Body The bag body 8 is a long cylindrical body, one end of which is closed, and the other end of which is opened to form an inlet 81 for the filler 9. The bag 8 is formed of a net-like cloth having air permeability.

<F> Compressor The compressor 2 blows out from the outlet by opening and closing a switch. The ejection hose 4 is a flexible hose having both ends opened, and has an ejection port of the compressor 2 and an air injection port 51.
Are connected.

<G> Filler The filler 9 is made of crushed stone, sand or the like, and the material of the filler 9 is determined depending on the use of sandbags and the like.

[0014]

Next, a method of using the above device will be described. <B> Installation of the bag The bag 8 is temporarily provided at the sandbag installation location, and the air suction pump device 5 is inserted into the injection port 81 of the bag 8. Air suction pump
The ejection pipe portion 56 of the device 5 is attached to the bag body 8.

<B> Suction of Filler The compressor 2 is operated. The compressor 2 blows air into a blowing hose 4 connected to the compressor 2. The other end of the ejection hose 4 is connected to an air injection port 51 of the air suction type pump device 5, and air is ejected from an annular air ejection port 53, and a jet stream directed toward the ejection pipe section 56 is formed. Then, a suction force due to the atmospheric pressure is induced upstream of the air discharge port 53. For this reason, air is sucked in from the suction nozzle 31 and extends over the entire length of the bellows hose 6.
As a result, only suction force is generated. The air ejected from the annular air discharge port 53 is ejected from the ejection pipe portion 56 into the bag 8.

Then, when the suction nozzle 31 is brought close to the filler 9, the filler 9 is sucked into the suction nozzle 31, passes through the bellows hose 6, the air suction type pump device 5, and flows from the ejection pipe 56 to the bag 8. Squirted into. Since the bellows hose 6 has flexibility, the suction nozzle 31 can be freely moved, and only by bringing the suction nozzle 31 close to the filler 9,
Can be sucked filler 9. Therefore, labor for the suction operation can be saved.

<C> Filling of Filler Filler 9 is blown out of blowout pipe section 56 together with air. The air escapes from the mesh of the bag body 8 to the outside, and the filling material 9 is sequentially filled from the back part 82 of the bag body 8 to the injection port 81. After filling the bag 9 with the filler 9,
The injection pipe portion 56 is pulled out from 1 and the injection port 81 is closed. This completes the installation of one sandbag.

<D> Installation of sandbag Further, in order to install the next sandbag, a bag 8 is temporarily provided on the upper part or the side of the sandbag which has been installed, the filling material 9 is filled, and then the sandbag is installed. Go.

[0019]

Embodiment 2 As shown in FIG. 3, in this embodiment, a suction hose 3 is additionally provided to the sandbag filling device of Embodiment 1. The suction hose 3 is a flexible hose having both ends opened,
The suction port of the compressor 2 and the suction nozzle 31 are connected. Air is sucked from the suction port of the compressor 2, and the air of the suction nozzle 31 is sucked through the suction hose 3.
For this reason, the suction force of the filler 9 of the suction nozzle 31 increases.

[0020]

[Effects of the Invention] The present invention is as described above, and the following effects can be obtained. <B> The operation of filling the sandbag bag with the filler can be mechanized, and the transportation and installation of the sandbag to the construction site can be omitted, so that significant labor can be saved.

<B> According to the present invention, the filling operation can be performed quickly, and the transportation and installation of the sandbag to the construction site can be omitted, so that the construction period can be shortened.

[0022] <C> for the filler using suction force generated over the entire length of the bellows hose to the air transport, can be efficiently hose conveying to avoid clogging accident of the filler effectively. In addition, the filler can be filled into the bag body by suctioning not only granular materials such as quarries and sand but also slurry-like materials such as mud.

<D> Since the suction force is positively applied to the start end side of the bellows hose, the transfer efficiency of the filler is improved in combination with the suction operation of the filler by the air suction pump device provided at the end of the bellows hose. higher, in particular the entire length of the case and the bellows hose mass of filler is large is effective when a long.
