Description

The present invention relates to an earth and sand conveying device suitable for carrying out and removing earth and sand generated during disasters and the like.

Conventionally, when removing earth and sand caused by a disaster, for example, it may not be possible to use heavy machinery depending on the local situation, and the work is often done manually.

The work involves digging up accumulated soil with a shovel, transferring it to sandbags or containers for transportation (excavation work), and when a certain amount has accumulated, transporting it out (transportation work), which is repeated.

However, during removal work, if there is a large amount of earth and sand that has been transferred to a container, it is difficult for one person to carry it, and two or more people are required. , workers have to repeatedly transport small amounts of soil that can only be carried by one person, which places a heavy physical burden on the workers.

Furthermore, if you are living in a house where there is not enough passageway for transportation, you will have to send containers for transportation from person to person, which not only requires a large number of people, but also requires the use of small, easy-to-carry containers such as buckets. , the amount that can be transported at one time is small, resulting in low work efficiency.

Light transport vehicles such as unicycles may be used for transportation, but they require wider passageways than when transporting by hand, making it difficult to use inside buildings, and even outdoors on steep slopes or narrow spaces. Because walkways can be dangerous, such as slips and falls, there are only a limited number of places and situations in which they can be used.

Furthermore, when transferring earth and sand to sandbags or containers for transport, there is a risk of injury from broken glass or china. The incidence will also increase.

Regarding this work, some prior art (for example, Patent Documents 1 and 2) has already been devised, but in all of them, the problem of having to do the work by multiple people and preventing injuries and accidents is to be solved. I'm taking it up.

This situation does not only affect ordinary citizens, but also the fire brigade, which is involved in similar operations immediately after a disaster when it comes to rescuing people buried in mud.

Public fire departments and the Self-Defense Forces are equipped with equipment such as conveyor belts, but they are expensive and difficult for the general public to purchase, difficult to manage, and difficult to operate. In addition to requiring knowledge, the equipment itself is large, so it actually takes more people to carry it in.

Embodiments of the earth and sand conveying device according to the present invention will be described below with reference to FIGS. 1 to 8.

The earth and sand conveying device 1 includes a gutter 2 that can be connected in the longitudinal direction by an insertion structure, a nozzle 3 that can adjust the direction of the water spout 3a to any angle and has a water volume adjustment function, and at least one of the nozzles 3. It has a support member 4 that supports the gutter 2 and is detachable at any position of the gutter 2.

The gutter 2 can include a gutter main body 2a with an open upper part, an outlet 2b having a plug-in structure, and a socket 2c having a plug-in structure. The spout 2b is provided at one longitudinal end of the gutter body 2a. The socket 2c is provided at the other longitudinal end of the gutter body 2a. The structure is such that gutters 2 of the same shape can be connected by inserting the spigot 2b into the receptacle 2c.

The spigot 2b may be a square pipe or a round pipe, and the socket 2c may be a pipe of the same shape with a diameter that allows the pipe of the spigot to be inserted. It should be noted that other structures of the insert and the socket may be used as long as the structure is an insert structure.

At one end of the gutter body 2a, there is a receiver molded along the shape of the gutter body 2a in order to prevent a step from forming when the gutter 2 is connected in the length direction and to reduce water leakage from the joint. A plate 2d is attached along the outer periphery of the gutter body 2a.

The gutter 2 can have a cross-sectional shape of a polygon, a semicircle, or a combination of a polygon and a semicircle. The gutter 2 can be formed of a thin metal or resin plate, and can be made lightweight.

The support member 4 to which the nozzle 3 is fixed is installed at any position in the longitudinal direction of the gutter 2 from the top of the gutter 2.

The support member 4 can be made into a U-shape by bending both ends of a metal plate at approximately right angles, and can be fixed to the gutter 2 with bolts 4b by attaching hexagonal nuts 4a or the like to the bent sides. The support member 4 is formed with a hole 4c into which the nozzle 3 is inserted and a hole 4d through which a bolt for fixing the nozzle 3 is passed (FIG. 8).

The nozzle 3 has a structure that allows a hose 5 to be connected to the primary side, and the water spout 3a at the tip has a universal joint structure, and the direction of the water spout 3a can be adjusted by moving it to an arbitrary angle to direct the water in any direction. Water can be sprayed.

Further, the nozzle 3 is provided with a lever-handle type ball valve 3b for adjusting the water pressure and amount to ensure the necessary water pressure and amount.

The hose 5 is connected to, for example, a water pipe or a water pipe or a hose connected to a vehicle with a pumping function (such as a fire pump truck).

When installing the gutter 2, pieces of wood, blocks 6, etc. are installed at the bottom of the gutter 2, and the slope is adjusted to match the length of the channel and the soil condition.

There are various situations in the field, and if the flow path needs to be bent, using bent members will not only make it impossible to ensure an effective flow path, but also cause safety issues if the scaffolding is unstable. It is no longer guaranteed that the work will be done properly.

In such a situation, as shown in FIG. 3, by placing the terminal end of the upstream gutter 2 on the side end of the downstream gutter 2, the flow path can be set at an arbitrary angle.

If the flow channel is long, it may be impossible to maintain the slope, but this can be resolved by installing a mud catcher such as a net at the end that can drain the water, and then installing a new flow channel with a slope. .

According to the earth and sand conveying device having the above configuration, the gutter 2 can be formed to be lightweight, so that it is easy to transport earth and sand to the site, and the plug-in structure makes it easy to assemble by connecting. Since the support member 4 supporting the nozzle 3 can be attached to any position of the gutter 2, it can be appropriately adjusted and attached to a position where earth and sand can easily flow.

By reducing or eliminating the number of people required to transport earth and sand using earth and sand conveying equipment, more people can be assigned to the excavation work, making it possible to complete the work in a shorter time compared to the current situation.

In particular, in rescue operations by fire brigade, self-defense forces, etc., it is expected that the effectiveness of saving lives will be enhanced by rescuing those in need of rescue from the earth and sand in a short time.

Next, the problem of injuries and accidents caused by reduced attention span due to worker fatigue is expected to be reduced by assigning more people to excavation work and distributing and reducing the physical burden on workers. can.

Furthermore, in aging areas, it can be expected to be effective in reducing the length of recovery work carried out by residents, which is caused by the aging and shortage of not only residents but also fire brigade members.

In addition, if not only earth and sand but also ash fall from a volcanic eruption occurs, assistance from public organizations such as disaster relief agencies cannot be expected, so if water supply equipment such as water pipes has not been damaged, assembly and Since the operating method is simple, even the general public can easily use it.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.
