Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a self-propelled sandbag forming machine for forming sandbags while collecting sand on site.

[Conventional technology]

Conventionally, sandbags have been widely used for flood control, weirs for river works, flood control of roads, and the like. Sandbags cannot be created and stockpiled, but are made when needed. for that reason,
In the event of a disaster, etc., it is required to create a large amount quickly.

Most sandbags are made manually,
Digging earth and sand and filling sandbags are labor intensive, so labor saving is desired.

Although there are few commercial sandbag production machines, the one shown in Fig. 6 is used in part.

In this sandbag forming machine, a sandbag mounting cylinder 104 is provided at a discharge port of a hopper 102 installed on a base frame 101 through a sand-sand meter 103, and sandbags 106 on a sandbag bag holder 105 are filled with sand and sand. is there. A plurality of sandbag receivers 105 are provided on the rotary table 107, and a bag tying device 108 for tying the mouth portions of the sandbags 106 and a conveyor 109 for unloading sandbags are provided at predetermined indexing rotation positions. .

According to this, it is possible to automatically perform the operations from supplying the sandbags to the sandbags 106, binding the sandbags 106, and carrying out the sandbags. Further, it is portable and can be loaded and transported on a large truck together with the base frame 101.

[Problems to be solved by the device]

The conventional example shown in FIG. 6 does not include the earth and sand collecting means and the self-propelled means, and therefore has the following problems (a) to (c).

(A) The size is increased to improve efficiency.

That is, since there is no means for collecting earth and sand, it is necessary to collect earth and sand from the ground with another shovel loader or the like and put it into the hopper 102. In this case, although the soil collection range is wide to some extent, it does not have a self-propelled means and cannot be easily moved.
The transportation distance up to 2 may be long, and it takes time to transport. If the hopper 102 is made large so that a large amount of earth and sand can be stored, the sandbag can be efficiently created without lowering the operation rate even if it takes a long time to transport. However, since the hopper 102 is upsized, the sandbag forming machine is upsized as a whole.

(B) Truck transportation is difficult.

Due to this large size, a large truck is required for transportation, and it cannot be transported by the normally used 2t truck. Therefore, it may not be possible to arrange a truck in an emergency such as a disaster. Moreover, a device such as a crane is required to load and unload the truck, which is inconvenient for loading and unloading.

(C) Limitation of installation position on site.

Since it is large and requires a device such as a crane for installation, it may not be possible to install it in an efficient position on site. This also reduces work efficiency.

The purpose of this device is to avoid heavy labor of workers,
It is an object of the present invention to provide a sandbag making machine which is compact and can efficiently make sandbags, is convenient for transportation to the site, and can be easily brought to a necessary place on the site.

[Means for solving the problem]

The sandbag forming machine of the present invention is one in which a hopper and a sand collecting device are mounted on a self-propelled trolley. The hopper has a discharge port for discharging earth and sand into the sandbag. The earth and sand collecting device excavates earth and sand and puts it in a hopper.

[Action]

While collecting the sand with the sand collecting device and putting it in the hopper, the sandbag is filled from the hopper with the sandbag to form the sandbag. Since the earth and sand collecting device and the hopper are mounted on the self-propelled device, the earth and sand collecting device and the hopper can be freely moved to an efficient place for collecting the sand and supplying the created sandbag. Transport to the site is carried on a truck or the like.
