Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backfill material loading vehicle capable of efficiently filling a backfill material in general civil engineering work or agricultural civil engineering work for forming culverts, gutters and the like.

[0002]

2. Description of the Related Art In the construction of culverts and gutters, the work of putting backfill materials such as crushed stones and volcanic rubble into excavated trenches is carried out. The vehicle is attached to the excavation trench side at regular intervals of about 3 m while being transported, the backfill material is dropped on the ground, and workers manually enter the culvert. Also,
In the backfilling work in an urban area with a narrow construction width, a method is used in which a backing material is dropped on the ground by a dump truck in which a cargo bed is dumped in a lateral direction, and a worker manually inputs and spreads the work.

[0003]

However, among the above-mentioned prior arts, the loading operation by the crawler type small transport vehicle has a drawback that the work efficiency is poor because the vehicle is stopped at a fixed distance at a rearward position, and In the construction of a culvert, there is a disadvantage that the field is damaged because the traveling, stopping and turning operations are repeated in the field. Also, a space is required to temporarily drop the backfill material onto the ground, but if this space cannot be secured, the worker must directly insert the backfill material from the transport vehicle into the excavation trench. There is a disadvantage that work efficiency is poor.

On the other hand, in the method using a dump truck in which the loading platform is dumped in the horizontal direction, it is difficult to perform the operation of dropping the backfill material evenly while traveling, and the worker once drops the backfill material to the ground. Work efficiency is poor because of the need for charging and spreading work. In addition, there is also a disadvantage that the vehicle becomes unstable because the load applied to the vehicle at the time of dropping is offset. Each of the above methods has a disadvantage that a great deal of labor is required for the worker, and a part of the backfill material is dissipated because the backfill material is once dropped on the ground.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and has excellent work efficiency because the backfill material is directly introduced into the excavation groove while traveling along the excavation groove, and the turning operation is excellent. Without damaging the fields,
It is another object of the present invention to provide a vehicle in which a backfill material can be introduced, in which the backfill material does not dissipate at the time of loading and labor of an operator can be significantly reduced.

[0006]
