Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a towed vessel, and more particularly, to a vessel which can be carried by a power shovel or a wheel loader to transport earth and sand, materials, and equipment.

[0002]

2. Description of the Related Art For example, in road paving work, dump trucks transport materials such as earth and sand and pavement boards to a construction site. However, depending on the situation at the site, the construction site is narrow, and the dump vehicle passes to the construction site. There are things you can't do. In such a case, it is necessary to temporarily place the materials and equipment at the construction site and manually transport the materials and equipment to the construction site.

When excavated soil is carried out from a construction site, excavated earth and sand is scooped by a bucket of a power shovel or a wheel loader, put into a dump truck carrier and carried out by a dump vehicle, but the construction site is narrow. If the dump truck cannot pass through to the construction site, it is necessary to manually transport the excavated soil to the dump truck and put it into the loading platform.

[0004]

However, manually transporting materials and equipment to a construction site or manually transporting excavated earth and sand into a dump truck carrier not only imposes a heavy burden on the worker, but also increases the burden on the operator. However, it is not preferable in terms of safety.

[0005] In view of the above problems, it is an object of the present invention to make it possible to transport materials and equipment without relying on humans even at construction sites where dump vehicles cannot pass.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, they can use a power shovel or a wheel loader even in a narrow construction site where a dump vehicle cannot pass. In many cases, the present invention has been completed by paying attention to the fact that materials and equipment can be transported by using such a power shovel or a wheel loader.

That is, a towable vessel according to the present invention is a towable vessel that is capable of carrying works such as materials and equipment by being towed by a power shovel or a wheel loader, and is connected to the power shovel or the wheel loader. A trolley provided so that it can be provided and a box shape with an open upper surface. A mounting position that can accommodate and hold the work centering on the upper part of the front wall surface, and the accommodated work can be discharged forward by its own weight. It is characterized by comprising a vessel main body rotatably supported by the carriage between a tilt position and a driving means for rotating the vessel main body between a mounting position and a tilt position.

One of the features of the present invention is that the trolley is pulled by a power shovel or a wheel loader, and the vessel body mounted on the trolley is tilted so that the work accommodated in the vessel body can be discharged forward by its own weight. It is in. As a result, even in a narrow space where a dump vehicle cannot pass, if there is a space where a power shovel or wheel loader can pass, the vessel of this example is towed by a power shovel or wheel loader to remove materials, equipment, excavated earth and sand, etc. It can be transported without human intervention.

The vessel body may be supported by any structure as long as the vessel body can be rotatably supported on the carriage. However, since it is necessary to withstand the load in the vessel body, the carriage has columns on both sides of the front edge. It is preferable to adopt a structure in which the vessel body is extended upward and a rotating shaft is attached to the upper ends of the left and right columns to rotatably support the vessel body.

That is, the bogie is constructed by connecting left and right L-shaped frames by a reinforcing frame and mounting wheels on horizontal portions of the left and right L-shaped frames, and has a rotating shaft at the upper end of the L-shaped frame. It is preferable to extend and support in the direction, and to support the upper end portion of the front wall of the vessel body on the rotating shaft.

The driving means may be any means as long as the vessel body can be rotated. A hydraulic cylinder is used, and the lower end of the hydraulic cylinder is swingably supported on the bogie, and the upper end is swung to the opening side edge of the vessel body. When freely supported, the vessel body can be rotated using the hydraulic pressure of a power shovel or a wheel loader.

It is preferable that the excavated earth and sand can be transferred directly from the vessel body to the bed of the dump vehicle without manual operation. Therefore, it is preferable that the opening front edge of the vessel body is set to the height of the loading platform of the dump vehicle at the inclined position.

Further, when the vessel body is tilted by the hydraulic cylinder, the vessel body can be repeatedly tilted due to the function of the hydraulic cylinder. Therefore, when the front wall of the vessel main body is formed in a sieve shape, it is possible to sort the work.

That is, the front wall of the vessel body is formed in a sieve shape on which a work smaller than a desired size can be dropped, and the work can be sorted by repeatedly swinging the vessel body near the tilting position by a hydraulic cylinder. Is good.

The height of the loading platform varies depending on the type and size of the dump vehicle to be used, and the height at which the work is introduced into the vessel body and the height at which the work must be discharged may differ depending on the working condition. Therefore, it is preferable that the height of the vessel body can be appropriately changed. That is, it is preferable to provide a lifting mechanism for raising and lowering the vessel body on the bogie.

For example, the bogie comprises an upper frame formed by connecting left and right L-shaped frames with a reinforcing frame, a lower frame supporting a wheel, and a lower frame supporting the wheels, and a lower frame mounted on the lower frame with respect to the lower frame. And an elevating mechanism for raising and lowering the upper frame. The upper end of the L-shaped frame of the upper pedestal extends horizontally to support a pivot axis, and the pivot axis supports the upper end portion of the front wall of the vessel body. Good.
