Description

[Detailed Description of the Invention] The present invention is capable of removing soil and other foreign objects (stone blocks, etc.) of a certain size or larger from debris generated during road construction, building foundation work, etc.
This relates to a device that separates and divides into sections.

In general, "residues generated during road construction, building foundation work, etc."
It is a mixture of earth and sand, earth lumps, stone blocks, concrete lumps, asphalt lumps, etc., and its viscosity and water content ratio vary, and its properties are extremely uneven, so it cannot be reused as is. It is extremely difficult.

If you try to separate these residues using a conventional fixed bar type or net sorting machine, if the viscosity and moisture are low, it will be divided into fine sediment below the mesh size and other types. Although it is relatively easy to separate soil clods that are larger than a mesh size, they become knotted products together with other foreign substances and cannot be separated.

Furthermore, if the viscosity or moisture content increases, most of the remaining raw material will turn into lumps and pass over the nodal surfaces, or will stick to the openings of the nodal surfaces and cause clogging. etc., and the animal no longer functions as a herd.

The present invention improves this and performs knotting using a conventional splitting machine.
These inseparable residues are divided into adjacent joints of joint surfaces configured with apertures of a certain appropriate size, and the dividing bars are shifted in phase by 180 degrees and repeated circular motions alternately to prevent clogging. If a foreign object (stone lump, etc.) that is larger than the opening of the sorting bar is found, a scale crusher with rotating blades is installed on the grain surface, and the crusher is separated. By supporting it on a fixed frame through an elastic member that precompresses toward the surface, the shikon is crushed into muscle products, and when foreign matter comes, this crusher overcomes the precompressing force of the elastic member. This makes it possible to send the foreign matter out onto the nodal surface and remove it as a nodal product without shattering the foreign matter that escapes above the nodal surface.

Next, an embodiment of the device of the present invention will be described based on the drawings.

1 and 2 indicate adjacent nodes and dividing bars in the present invention, and the openings of a certain appropriate size also constitute a node surface.

These adjacent striations and dividing bars 1, 2 that make up this nodal surface follow the rotation of the drive shafts 5, 5' via eccentric bearings 3, 3', 474', and move vertically parallel to the direction of movement of the raw material. The continuous repeating of circular motion in a plane with a phase shift of 1800 degrees is shown in the order of 1, 0, m, W in Figure 4.

The drive shafts 5, 5' are mounted on bearings 7, 7' of the fixed frame side plate 6.
The electric motors 8, 8' and the tuning mechanism 9 provide rotational movement in the direction of the arrow shown in FIG. Kakumine crusher 1, its rotary blade 11 is jointed, dividing bar, 2
The drive shaft 13 and arm 14, which are inserted between the frame side plate 61 and the bearing 12, are rotated by an electric motor 15 in the direction of the arrow shown in FIG. 2 through a drive mechanism (not shown) of the device.

In addition, this crusher 10 has a structure in which the arm 14 of the drive mechanism of the device is provided with an adjustable pre-compression using a spring 16, which is an elastic member, so that if a force greater than the given sub-compression is applied, To do this, lift this spring 16, rotate it around the drive shaft 13 above the surface of the muscle, and knot it.
It is configured to move upward away from the dividing bar, 2. What is shown in FIG. 5 shows a modified embodiment,
This figure shows the use of an outer frame 17 and an inner frame 18 so that adjacent joints and dividing bars of the grizzly deck or bar deck can be moved alternately. Grizz IJ bars 2, 2, . Grizzrivers 1, 1, . . . are attached via 4, 4'. and drive shafts 5, 5'
An outer frame 17 and an inner frame 18 are attached to each of the eccentric parts shifted by 1800 degrees, and the drive shafts 5 and 5' are driven from motors 8 and 8' via couplings 21 and 21r. The outer frame i7 and the inner frame 18 are moved alternately, and the adjacent bars are accordingly moved alternately. 9 indicates a tuning chain.

This embodiment has the feature that the bearing part can be simplified, and if a crusher is disposed on the surface of the shaft in the same manner as described above, the same function can be achieved.

Now, as shown in Figure 2, dump trucks, bulldozers,
A clod of soil (machine) is thrown in from a loading path c on a concrete wall b using a suitable loading machine a such as a power shovel or backhoe.
The raw material residue with high viscosity and high water content containing foreign matter (stone lumps, etc.) is divided into rings without clogging by the above-mentioned movement of the separating bars 1 and 2, and is separated while moving forward. Sent out.

Next, by the rotating blades 11 of the crusher 10, which has the above-mentioned structure and function, and which is installed at an appropriate position on the upper part of this sorting bar, 2, the souls of the warriors are crushed and made into Tsurushita products, which are then cut into pieces. It falls into the hopper e under the sorting machine, ages, and the sorting bar,
When a foreign object f with a block size of 2 or more comes, these foreign objects f! However, without being crushed, the spring 16 is lifted to escape the scale crusher 10, and the scale is sent out onto the nodal surface, where it is discharged and removed outside the grand wall g as a nodal product. Therefore, by performing the above-mentioned functions, this device is most suitable for removing foreign matter larger than a certain size from raw materials containing soil clods and foreign matter that cannot be treated with conventional knotting and separating machines. There is.

In addition, even when handling raw materials with high viscosity and high water content, this device has far superior performance compared to conventional sorting machines in that it can strain and separate without clogging. can demonstrate.
