Description

[Detailed Description of the Invention] The present invention relates to a new power shovel attachment for removing sand, etc.

A power shovel is equipped with various attachments, and by replacing these attachments, various functions can be achieved.

However, among the conventionally known power shovel attachments, there is no attachment suitable for efficiently removing dirt and the like accumulated on a surface where an obstacle exists at a low position from the surface.

For example, if a belt conveyor for carrying earth and sand is installed with a small gap between the ground and the ground, if a power shovel with a packet-type attachment is used to remove the earth and sand that accumulates under the belt conveyor, the packets will be removed from the belt conveyor. This causes problems such as the packets cannot be removed sufficiently and the packets come into contact with the belt conveyor and destroy the belt conveyor.

The present invention provides a flat, scattered sand removal structure having a vertically long and planar bottom plate, and also provides an attachment to the arm of a power shovel located above and at the rear of the sand removal surface.

This provides a power shovel attachment that solves the above problems.

That is, the present invention is a power shovel attachment having a flat, scattered sand removal structure having at least a vertically elongated and flat bottom surface, and a mounting tool at the rear portion of the sand removal surface.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to these drawings.

FIG. 1 is a plan view showing a typical embodiment of the power shovel attachment of the present invention, and FIG. 2 is a side view thereof.

Moreover, FIG. 3 is a perspective view showing another typical aspect.

The power shovel attachment 1 of the present invention is characterized in that it has a flat, scattered sand removal structure 2 having at least a vertically elongated and flat bottom surface, and that it has a mounting tool 3 at the rear of the sand removal surface.

Since the sand removal structure 2 has a vertically long and flat bottom plate and is flat, it can be inserted into a narrow gap.

Therefore, by attaching it to the arm of a power shovel using the attachment 3 located at the rear of the sand removal surface, it is possible to efficiently remove dirt and the like accumulated on the surface where the obstacle is present at the low position.

In the present invention, the sand removal structure 2 is not particularly limited as long as it has a flat, scattered shape with at least a vertically long and flat bottom plate.

For example, it can basically be composed of a flat plate, but side plates 4 of an appropriate height are provided on both sides of the plate to prevent the scooped earth and sand from overflowing or to provide strength. It is preferable.

Further, if necessary, a reinforcing material may be attached to further strengthen the structure.

The length of the sand removal structure 2 may be appropriately determined according to its intended use.

For example, when removing earth and sand accumulated under the belt conveyor, the length is generally determined to be slightly longer than the width of the belt conveyor.

As long as the power shovel attachment of the present invention has the above-mentioned sand removal structure and the attachment is present on the rear part of the sand removal surface, known structures may be applied to the other structure without particular limitation.

For example, as shown in FIG. 1, a structure in which the attachment 3 to the arm is simply attached to the rear of the sand removal structure 2, or a structure in which the attachment 3 to the arm is simply attached to the rear of the sand removal structure 2, as shown in FIG. It is preferable to have a structure in which the

FIG. 4 is a diagram showing a state in which the power shovel attachment 1 of the embodiment shown in FIG. 1 is attached to the arm 6 of the power shovel to remove soil accumulated under the belt conveyor.

A shows a state in which the earth and sand under the belt conveyor is scooped out by a power shovel, and B shows a state in which the scooped out earth and sand is returned onto the belt conveyor 7.

As described above, the power shovel attachment of the present invention has a characteristic not found in conventional power shovel attachments, such as being able to efficiently remove earth and sand from a surface where an obstacle exists at a low position from the main surface.
