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 crush concrete lumps generated after crushing structures such as reinforced concrete, and dirt and stones generated during civil engineering work. Concerning a separation bucket for separating.

Conventional technology Concrete lumps etc. generated after dismantling reinforced concrete structures etc. are not completely discarded, but by separating large and small lumps, only large lumps are discarded, and small concrete lumps are used as secondary products instead of earth and sand for land preparation. It is currently being used for other purposes or as recycled aggregate. For this reason, it is known that in a bucket attached to a power shovel or the like, concrete lumps, earth and stones, etc. can be separated into large and small pieces by providing holes in the bottom of the bucket. 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. Furthermore, when separation is carried out in the bucket, separation is performed at the bottom of the bucket, but since it is difficult to shake and move concrete lumps, soil, etc. It had the disadvantage that it could not fall through the hole in the bottom and separation was not complete.

Problems to be Solved by the Invention The present invention uses a separating bucket that can be moved in the same state as it is scooped up with a bucket, and then easily separated into large and small pieces of concrete lumps, soil and stones at an appropriate predetermined location. This is what we are trying to provide.

Means for Solving the Problems The present invention is configured such that a separation chamber communicating with the bucket is connected to the back of the bucket.

Function By scooping up concrete lumps, soil and stones, etc. with the bucket, moving the bucket to the separating section, and then tilting the bucket upward, the concrete lumps and soil and stones are moved to the separation chamber provided at the back of the bucket, and the movement In addition, if necessary, shake the bucket several times to allow small concrete lumps and dirt to fall from the separation chamber, and separate large lumps from small lumps and dirt.

Embodiment FIG. 1 is a side view of an embodiment of the present invention, FIG. 2a is a left side view in FIG. 1, and FIG. 2b is a left side view in FIG. 1 when the closing plate is attached. FIG. 3 is a right side view of FIG. 1, and FIG. 4 is a bottom view.

Reference numerals 1a and 1b denote bucket mounting members, and the bucket mounting members 1a and 1b are fixed to the main plate 3 of the bucket 3 by welding or the like. The bucket mounting members 1a and 1b have pins 1a-1 and 1b- attached to the arm 9 of a hydraulic construction machine such as a power shovel.
It is rotatably attached via 1.

A plurality of claws 7 are provided at the tip of the main plate 2, that is, at the entrance of the bucket, to facilitate scooping up concrete lumps and the like into the bucket. Also, main plate 2
An opening 6 is provided diagonally above the back of the
This opening 6 also communicates with the bucket bag, and a deep separation chamber 4 is fixed to the main plate 2 by welding or the like, diagonally above the back of the bag bag 3. 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. 2b is a diagram in which a closing plate 8 is attached to close the opening 6, and when there is no need to separate concrete lumps etc. into large and small pieces, by attaching the closing plate 8 to this opening 6, it is possible to scoop up Concrete lumps and the like can be transported to a truck or the like while being accommodated in the bucket 3. 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 bag 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,
By operating the arm 9, the bucket 3 is moved to a required position, and a lump of concrete 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 blocks etc. are to be separated,
Tilt the entrance of Bucket 3 upwards on the spot,
That is, by arranging the separation chamber 4 to be below the bucket 3, concrete blocks and the like are carried into the separation chamber 4. In the process of the concrete lumps flowing into the separation chamber 4, they are separated into large and small pieces by the holes 5 of the separation chamber 4, and the small ones fall. The concrete lumps, etc. are separated into large and small pieces by moving the lumps and dropping smaller lumps from the holes 5 of the separation chamber 4. The large concrete mass remaining in the separation chamber 4 is then transported to a predetermined location, such as a truck, and discharged by directing the inlet of the bucket 3 downward.

Further, when transporting a concrete lump that does not need to be separated, the opening 6 is closed with a closing plate 8 to prevent the concrete lump from entering the separation chamber 4.

In the above embodiment, a separation chamber was provided at the back of the bucket, and no hole was provided at the bottom of the bucket for separating concrete lumps, etc., but holes may also be provided at the rear of the bottom of the bucket. For example, place about 1/3 of the bottom of the bucket on the separation chamber side of the bottom of the bucket.
A hole for separation may be provided in a continuous manner with the separation chamber by about 1/4.

Effects of the Invention The present invention has a separation chamber connected to the back of the bucket, and makes it possible to separate concrete lumps by tilting the bucket and moving the concrete lumps, etc. to the separation chamber. Compared to conventional buckets, which perform separation work only at the location where concrete lumps, etc., are scooped up, separation work can be performed at any location, and concrete lumps, dirt, etc. can be separated between the bucket and the separation chamber. can be moved, separation can be carried out efficiently and work efficiency can be greatly increased. Also, compared to transporting concrete blocks etc. in buckets to a specially installed separation device at another location, special equipment is not required.
Moreover, it has the effect of being able to be separated by a simple method. Furthermore, if separation is not required, a closing plate can be installed to prevent concrete lumps from entering the separation chamber. It has a wide range of uses, as it can transport concrete blocks, etc., to a designated location.
