Description

[Detailed Description of the Invention] The present invention relates to a device for squeezing out moisture from the contents of a bucket of a shovel-type excavator.

A shovel type excavator is generally a mechanical device that excavates and transports earth and sand using a bucket, and its work targets are wide-ranging, including rock masses, gravel, sand, normal soil, soft soil, and mud.

Work objects with high moisture content, such as mud, should be
Various difficulties arise when removing soil from buckets and transporting it using special transport machines. That is, for example, when loaded on a truck platform, the material may flow and overflow, water may run down from gaps in the cargo platform and stain the road surface, and because of its fluidity, it cannot be transported by a belt conveyor.

For this reason, it is desirable to drain (reduce the moisture content of) workpieces with a high moisture content that have been scooped into the bucket before being discharged from the bucket.

In order to meet these demands, buckets made of perforated plates are known and are widely used, for example, as dragline buckets for collecting gravel from riverbeds. In this case, the perforated plate is a general term for a plate-like member that allows water to flow and prevents earth and sand from flowing out, and the size and shape of the holes does not matter. Therefore, for example, a plate having slits also belongs to the perforated plate in the present invention.

When excavating earth and sand with a high moisture content using a conventional bucket made of perforated plates as described above, if the object to be worked with has good internal water permeability, such as sand, most of the contained moisture will be absorbed by gravity. It flows down and out of the bucket, making it easy to handle.

However, in the case of workpieces such as clayey earth and sand that retain their moisture content inside due to capillary action, it is difficult to remove the moisture content even if the workpiece is kept in a bucket made of perforated plate. Do not drip. The moisture contained in the workpiece cannot be quickly discharged unless it is compressed and squeezed out.

The present invention was developed in view of the above-mentioned circumstances, and is intended to provide a shovel draining device that can quickly and easily squeeze out the moisture content from a workpiece with a high moisture content dug into a bucket. be.

In order to achieve the above purpose, the draining device of the present invention is provided with a lid made of a perforated plate that can be opened and closed freely on the bucket of a shovel type excavator, and a lid made of a perforated plate is installed near the center of the lid toward the inside of the bucket. When the lid is closed, the contents of the bucket are compressed by the bulge, and the water contained in the contents of the bucket, which has a high moisture content, flows out from the holes of the perforated plate member. It is characterized by being configured in such a way that it can be used.

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

1 is a bucket for a shovel, which is made of a perforated plate and is pivotally attached to the tip of an arm 2 with a bucket pin 3. 4 is a hydraulic cylinder for rotating the bucket 1.

The bucket 1 is provided with a lid 5 made of a perforated plate that can be opened and closed freely. In this embodiment, it is rotatably supported by the bucket pin 3 and is provided with a hydraulic cylinder 6 for opening and closing operations. As a result, when the hydraulic cylinder 6 is expanded or contracted, the lid 5 is opened and closed as shown by arrows A and B.

A cone 7 made of a perforated plate is attached near the center of the bucket side surface of the lid 5.

When implementing the present invention, the shape of the member attached to the bucket side surface of the lid 5 may be conical as shown in FIG. 3A, or pyramidal as shown in FIG. 3B. , it may be an irregular hemisphere as shown in FIG. 3C. In short, it is sufficient to provide a hollow member made of a porous plate (that is, water permeable) that bulges out from the inner surface of the lid 5 toward the inside of the bucket.

When soil with a high moisture content is excavated with the bucket configured as described above, when the hydraulic cylinder 6 is extended and the lid 5 is closed, the bulge made of a perforated plate (the cone 7 in this embodiment) will dig up the soil. The earth and sand are compressed and squeezed out of water. The squeezed water is poured into a bucket 1, a lid 5, or a cone 7.
Since the water flows out through the water holes, the soil remaining in the bucket solidifies and becomes easier to handle. That is,
This allows them to be stacked on the loading platform of a truck or transported on a belt conveyor, and there is no risk of soiling the road surface with dripping muddy water.

As detailed above, when the shovel drainage device of the present invention is applied, water can be quickly and easily squeezed out from the workpiece with a high moisture content excavated in the bucket, significantly reducing the subsequent soil transport work. It has the excellent practical effect of making shovel work easier, and greatly contributes to improving the efficiency and safety of shovel work.
