Abstract

PROBLEM TO BE SOLVED: To make the whole constitution of a concrete crushing/classifying equipment compact and make the equipment freely movable, in a crushing/ classifying equipment for classifying crushed concrete formed by disassembling a reinforced concrete structure into concrete rubbish (glass, ceramics) and reinforced iron bars (metal refuse). SOLUTION: The concrete crushing/classifying equipment is constituted of a bucket device 1 which is freely movable and finely crushes concrete crushed materials into crushed rubbish having particle size smaller than the desired grain size and a classifying device 10 which classifies resource materials 17 (the crushed rubbish 9) being directly fed into a hopper 11 from the bucket 2 by a classifying means and which is freely movable. In this equipment, the hopper 11 is formed in the size corresponding to the size of the bucket 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete crushing and separating apparatus for separating crushed concrete produced by dismantling a reinforced concrete structure into concrete pieces (glass, ceramics) and reinforcing bars (metal scraps).

[0002]

2. Description of the Related Art Conventionally, a large-sized apparatus for dismantling a concrete structure and crushing it has been known. There is also known a separation apparatus that separates crushed concrete crushed materials into concrete glass (glass, ceramics, etc.) and reinforcing steel (metal scrap).

[0003]

However, if a large number of concrete crushed materials are to be separated in a series using the large crushing device and the sorting device, a large plant is required. Therefore, it is inconvenient to perform the sorting operation in an arbitrary small space according to the location of the concrete structure. The concrete crushing / sorting device according to the present invention is proposed to solve such a problem.

[0004]

The gist for solving the above-mentioned problems of the concrete crushing / sorting apparatus according to the present invention is as follows.
A movable bucket device for crushing the crushed concrete into crushed pieces having a desired particle size or less; And a movable sorting device formed in a size corresponding to the size.

The separating means comprises at least a magnetic body and a cylindrical drum rotatable along an outer peripheral surface of the magnetic body, and the magnetic body extends over a required range of an inner peripheral surface of the drum. It is included that it is provided.

According to the concrete crushing / separating apparatus according to the present invention, the bucket and the separating apparatus are movable, and
Since the whole structure is small and compact, concrete is broken into crushed pieces at the place where the concrete structure is crushed, and the crushed pieces are further divided into concrete pieces (glass, ceramics) and reinforcing bars (metal scraps). And can be separated. Therefore, there is no need to transport the crushed concrete to the sorting plant.

[0007]

Next, a concrete crushing and separating apparatus according to the present invention will be described with reference to the drawings. Crushed concrete structures (concrete waste,
(For example, a particle size of about 30 cm to 50 cm)
Bucket device 1 that divides into crushed pieces of 0 to 40 mm
As shown in FIG. 1, a crusher (crusher) is provided in addition to a bucket 2 mounted on a shovel car or a shovel loader, and a hydraulic jack 3 is mounted on a shaft 4. A liner 5 to be pressed;
A receiving liner 6 disposed corresponding to the liner 5,
Consists of

[0008] A concrete gallery 7 is scooped and put between the liner 5 and the receiving liner 6, the hydraulic jack 3 is operated to extend the rod 3 a, and the liner 5 is rotated about the shaft 4 to rotate the liner 5. The concrete waste 7 is strongly pressed by 5 and the receiving liner 6, and the concrete waste 7 is sequentially crushed and divided.

Incidentally, in order to divide the concrete waste 7 into a desired particle size, an adjust plate (not shown) is provided on the liners 5, 6 to adjust the width of the discharge port.

The crushed glass 9 having a particle size of, for example, 20 mm to 40 mm is provided in the lower gap 8 with the liners 5 and 6.
Fall naturally from. The crushing waste 9 is applied to the bucket device 1
Into the hopper 11 of the sorting apparatus 10 located at the lower position.

The structure of the separation apparatus 10 will be described. As shown in FIG.
A hopper 11 having a size corresponding to the bucket 2, and a cylindrical drum 1 provided below an outlet of the hopper 11.
2, a substantially semi-cylindrical magnetic body 13 (see FIG. 3) disposed inside the drum 12, and a driving device 14 (a driving motor 14a and a belt or chain 14b for rotating the drum 12 in a certain direction). And a pulley 14c) which rotates integrally with the drum 12, a flow rate adjusting handle 15, and a separation plate 16 provided at a lower portion, and is movable. Note that the sorting apparatus 10 may be provided with a caster for movement on the lower surface. A scraper is provided on the outer peripheral surface of the drum 11 opposite to the side where the crushing waste 9 flows down to scrape off the rebar scrap adsorbed and retained on the drum surface by magnetism.

The magnetic body 13 is, for example, a permanent magnet or an electromagnet. As shown in FIGS. 3 and 4, the magnetic body 13 has a substantially semi-cylindrical magnetic body. It is arranged at a slight angle (about 20 °).

This is because, as shown in FIG. 3, the resource material 17 such as rebar scrap is dropped over the central vertex of the mountain-shaped sorting plate 16. In addition, hopper 1
To check the flow rate, etc., on the housing for mounting 1 etc.
A confirmation window or an inspection window (not shown) may be provided at an appropriate location.

The crushing waste 9 put into the hopper 11 by the separating device 10 is dropped from a lower discharge port while being adjusted by the flow rate adjusting handle 15, and is rotated by a driving device 14 in a predetermined direction. 12 is dropped on the outer peripheral surface.

By the magnetic force of the magnetic body 13 disposed close to the inner periphery of the drum 12, the resource material 17 such as rebar scraps in the crushing waste 9, as shown in FIG. Surface and the other concrete waste 18 is not adsorbed on the outer peripheral surface of the drum 12,
Natural fall to the right of 6.

When the resource material 17 crosses the vertex of the chevron-shaped disc 16, it is released from the magnetic force of the magnetic body 13 and falls naturally on the left side of the disc 16. The rebar scraps remaining on the outer peripheral surface of the drum are scraped off by a scraper.

In this manner, the concrete crushing and crushing device of the present invention in which the bucket device 1 and the sorting device 10 are movable.
It becomes a separation device, and the whole configuration is formed compactly.

[0018]

As described above, the concrete crushing / sorting apparatus according to the present invention comprises a movable bucket device for crushing concrete crushed material into crushed pieces having a desired particle diameter or less, and And the movable hopper is formed into a size corresponding to the bucket and the movable hopper is separated from the concrete structure. In that place, it has an excellent effect that it is possible to easily separate the reinforcing steel and concrete crushed waste immediately. In addition, since it is not necessary to transport the concrete waste to the sorting plant, there is an excellent effect that the construction period is shortened and the cost is reduced.

The separating means comprises at least a magnetic body and a cylindrical drum rotatable along an outer peripheral surface of the magnetic body, and the magnetic body is provided over a required range of an inner peripheral surface of the drum. So that it can be separated efficiently.
