Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a bucket that is attached to a power shovel or the like, and is used to reduce the size of concrete blocks that are created after crushing structures such as reinforced concrete, and dirt and stones that are created during civil engineering work. Regarding the separation bucket to be separated.

Conventional technology Occurs after dismantling structures such as reinforced concrete.
Concrete slabs, etc., are never discarded; by separating them into large and small chunks, only large chunks are discarded, and small concrete chunks can be used as secondary products instead of earth and sand for land leveling, or recycled as recycled aggregate. This is currently being done by making holes in the bottom of buckets that are attached to power shovels, etc.

It is known to separate concrete blocks, soil and stones into large and small pieces. However, since it falls from the bottom, it is separated at the same place it was scooped up, which is very inconvenient when it is desired to separate it at another place. In addition, when separating with this bucket, separation is performed at the bottom of the bucket, but since it is difficult to shake concrete lumps, soil and stones, etc. in the bucket, small lumps and dirt that have risen to the top of the bucket had the disadvantage that it could not fall through the hole in the bottom of the bucket, and separation was not complete.

Problems to be Solved by the Invention The present invention provides a separation bucket that allows concrete lumps, soil, and stones to be scooped up with a bucket, moved as they are, and then easily separated into large and small pieces at an appropriate predetermined location. This is what we are trying to provide.

Means for Solving the Problems The present invention provides a portion 1i on the back of the bucket that communicates with the bucket.
It was constructed so that llll chambers were connected.

Scoop up concrete lumps, soil and stones, etc. using the action bucket 1~,
By moving the bucket to the separation section and then tilting the bucket to the -F position, the concrete lumps and debris are transferred to the separation chamber provided at the back of the bucket. By shaking, small concrete lumps and stones fall from the separation chamber, and large pieces of concrete are separated from small lumps and stones.

Embodiment Figure 1 is a side view of an embodiment of the present invention, Figure 2 (a)
is the left side view in Figure 1, Figure 2 (1) is the left side view in Figure 1 when the closing plate is installed, and Figure 3 is the left side view in Figure 1.
The right side view in the figure, and FIG. 4 is a bottom view.

1a and Ib are bucket attachment members, and the bucket attachment members 1a and 1b are fixed to the main plate 2 constituting the bucket 3 by welding or the like. And bucket attachment members 1a, 1b
is rotatably attached to an arm 9 of a hydraulic construction machine such as a power shovel via bins 1a-1 and 1b-1.

At the tip of main plate 2, that is, at the entrance of the bucket? 12 claws 7
is provided to facilitate scooping up concrete lumps, etc. into the bucket. Further, an opening 6 is provided diagonally above the back of the main plate 2, and this opening 6 communicates with the bucket, and a separation chamber 4 with a depth is provided diagonally above the back of the bucket 3 for welding, etc. It is fixed to the main plate 2 by. The separation chamber 4 is formed by a grid having holes 5 of a predetermined size, and has a structure that allows the separation of large and small concrete lumps, etc., and is also welded to the bucket attachment members 1a and 1b.

FIG. 2(b) is a diagram in which a closing plate 8 is attached to close the opening 6. When there is no need to separate concrete blocks etc. into large and small pieces, by attaching the closing plate 8 to this opening 6, The scooped-up concrete lump or the like can be transported to a truck or the like while being accommodated in the bucket 3. In addition,
In the above embodiment, the closing plate 8 is attached to the main plate 2 with screws or the like, but it may be provided inside or on the outside of the bucket 3 as a sliding or rotating opening/closing plate.

Next, the operation of this embodiment will be described.

With the closing plate 8 removed from the opening 6, the bucket 3 is moved to a desired position by the operation of the //-mu 9, and a concrete lump or the like is scooped into the bucket 3.

Then, the bucket 3 is moved by the arm 9 to a place where large and small concrete lumps, etc. are to be separated, and at that point, the inlet of the bucket 3 is tilted upward, that is, the separation chamber 4 is placed below the bucket 3. , Concrete blocks, etc. will be brought into Separation All 4. In the process of flowing concrete into the separation chamber 4, it is separated into large and small pieces by the hole 5 of the separation chamber 4, and the small pieces fall, but the bucket 3 is shaken as necessary. By moving the separated "all-white" concrete 1 to 1 and dropping small lumps from the hole 5 of the separation chamber 4, large and small concrete lumps, etc. are separated. The large concrete lump remaining in the separation chamber 4 is then transported to a predetermined location, such as a truck, and is discharged by directing the inlet of the bucket 3 downward.

Furthermore, when conveying concrete that does not require separation, the opening 6 is closed with a closing plate 8 to prevent concrete lumps from entering the separation chamber 4.

In the above embodiment, a separation chamber was provided at the back of the bucket, and no holes were provided at the bottom of the bucket for separating concrete blocks, but holes may also be provided at the rear of the bottom of the bucket. For example, a separation hole may be provided on the separation chamber side of the bottom of the bucket so as to be continuous with the separation chamber about 1'3 to 174 degrees from the bottom of the bucket 1.

Effects of the Invention The present invention has one separation chamber on the back of the bucket! l! By tilting the bucket and moving the concrete lumps, etc. to the separation chamber, the concrete lumps, etc. were separated into ICs.
Compared to conventional buckets with holes in the bottom, which require separation work only at the point where concrete lumps, etc. are to be scooped up, separation work can be done at any location.
In addition, since concrete lumps, soil, and stones can be moved between the bucket and the separation 7, separation can be carried out efficiently and work efficiency can be greatly increased. In addition, compared to transporting concrete blocks etc. in 1 bucket to the equipment installed in 11 locations, the effect is that special equipment is not required and it can be separated using a simple method. have Roughly speaking, if separation is not required, r11 is used to prevent concrete 1, lumps, etc. from entering the separation chamber.
Since it is possible to attach a chain plate, in that case, by attaching a closing plate, it is possible to reliably transport the concrete in the bucket to the specified location. There is a wide roar.
