BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of cutting artificial turf in a laid state and discarding it, and a cutting device used therefor.

[0002]

2. Description of the Related Art In recent years, sports facilities have been enhanced as the sports population has increased. Traditionally, surface materials for sports facilities were mainly clay, anzker and natural grass. However, such natural surface materials are difficult to maintain, and in the case of natural grass, the pain caused by playing is so severe that it is not possible to use it frequently. Therefore, many artificial all-weather surface materials have been developed and constructed. In particular, sand-containing artificial turf has been laid on tennis courts, soccer and baseball grounds for more than a dozen years due to its durability and aesthetics, and has also been laid on the rooftop and other places as gateball courts. These sand-containing artificial grasses have been used very well and are still expanding, but there are many coats that are reaching the end of their lives due to aging, such as partial wear, fatigue, and discoloration. In many cases, they are replaced with new sand-containing artificial grass, but the problem is the disposal method. Artificial grass with sand is generally difficult to cut,
Lifting with a crane to drop the sand, then cutting the artificial grass and discarding it, removing the sand little by little from the end and removing it, then cutting, or plowing the artificial grass with sand, then sucking the sand, The method of removing the sand, cutting the artificial turf and discarding it is taken. However, on the rooftop, it may not be possible to use a crane, and the work environment and surrounding environment may deteriorate even on a general ground, and it is not always possible to use these methods anywhere.
Further, since it is difficult to dispose, the method of repairing an artificial lawn in Japanese Patent Laid-Open No. 5-156603 proposes a method of using old artificial grass as a base layer and laying new artificial grass on it. While this is temporarily effective, it is not a universal method and is not universal. In the end, it will be necessary to remove all of them, and at the same time as stacking, it will take time and effort to adjust incidental equipment such as nets.

SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned problems all at once, and is economical, and a method for cutting artificial turf for safely removing it without deteriorating the working environment and the surrounding environment, and a method therefor. The purpose of the present invention is to provide a cutting device for use in.

[0004]

The present invention adopts the following means in order to solve the above-mentioned problems.

That is, the method for cutting artificial turf according to the present invention is as follows:
When cutting the artificial turf in a laid state, after the cut portion of the artificial turf is floated from the floor, the floating portion is cut with a cutter, and the artificial used for that The lawn cutting device is provided with a mechanism (A) for slightly lifting the laid artificial grass, a disc cutter (B), and a self-propelled mechanism (C) capable of moving forward while cutting, and these (A) to (C). The main body of which mechanism has a drive mechanism
It is characterized in that it is provided on one side of (D).

[0006]

According to the present invention, as a result of diligent study on a method of removing and discarding used artificial grass, especially sand-containing artificial grass, the artificial grass is used in an extremely wide state. Cutting is the first decision. However, if the cutting can be done in the laid state, the work including the subsequent processing can be extremely simplified. However, artificial grass, especially sand-containing artificial grass, cannot be cut in the sand-containing state with a normal blade. Therefore, we used a grinder type disc cutter and succeeded in cutting it finely. In order to conveniently use such a disc cutter, the artificial grass, which is the object to be cut, is lifted from the floor to a distance that the disc cutter does not reach, and when it is applied to the cutter, the cutting is performed extremely smoothly. be able to.

The sand used in the sand-containing artificial grass is not particularly limited, and may be natural silica sand, soil, antucar, etc., or a mixture of plastic or glass beads, or 100% plastic or glass. These beads do not hinder the idea of the present invention.

The artificial turf is generally laid on the asphalt concrete of the roadbed, soil hardened with concrete or a soil improving material, and the like. Alternatively, an underpad may be sandwiched in between to enhance the cushioning property. Polyethylene or polypropylene foam for the underpad,
Styrene butadiene rubber foam, vinyl chloride foam, nitrile butyl rubber foam, etc. are used.

In the case of construction of artificial turf, especially sand-containing artificial turf, these are likewise laid and not entirely adhered. However, the seams are partially coated with adhesive on both sides of a tape-like sheet, one of which is bonded to artificial grass and the other of which is bonded to the roadbed to prevent peeling of the seams. When the underpad is not used, the artificial turf members are similarly bound with the above-mentioned tape for the purpose of preventing the joint portion of the artificial turf from peeling off, and the other surface is fixed to the roadbed.

In the present invention, the adhesion of the seam portion is physically peeled off by using a knife-like raising tool at the seam portion, and then the plow-shaped or wedge-shaped artificial grass lifting mechanism is used under the artificial grass at the portion to be cut. Insert it into the stand and lift it up, and cut the floated part with a disk cutter. For cutting, a diamond cutter coated with diamond powder around the disc or a normal disc cutter in which carborundum, hard alumina, etc. are hardened with an adhesive can be used, but a self-propelled cutter is preferable because it is a work in a wide field. . The components of this self-propelled cutter equipment are a mechanism that slightly lifts the laid artificial grass and a self-propelled mechanism that can move forward while cutting with a disc cutter. The mechanism for lifting the artificial grass is to float only the object to be cut, in order not to damage the roadbed at the time of cutting, or to cut only the artificial grass and the composite of the artificial grass and the underpad. The height that can be floated may be about 3 to 5 cm, and the height that is easy to cut is selected, and it is not necessary to make it too high. Artificial grass with sand is very heavy, but it is not particularly difficult to insert a wedge-shaped object and lift it by 3 to 5 cm. This wedge is composed of two plates or has a groove, and there is a space into which the blade of the disc cutter can be inserted. The artificial turf with sand or the artificial turf structure with sand containing the underpad is cut, and the cutting progresses as the car advances. Even if the sand is contained, the sand is removed by the rotation of the disk cutter, so the cutting is not hindered. For the self-propelled type, power may be simply connected to the car, and it may be rotated by a motor so that speed control can be performed. Further, the size of the artificial grass to be cut can be a size that can be carried by hand, or a size that can be loaded on a pallet and that corresponds to the processing method. Since the sand-containing artificial grass can weigh up to 30 kg per square meter, it is preferable that the size is about 50 cm to 1 m square. If there is a forklift,
A size of about 1.5m x 2m is advantageous in work.

The present invention will be described in more detail with reference to the drawings.
FIG. 1 is a conceptual diagram of a self-propelled sand-containing artificial turf cutter, and 1 is a disc cutter portion. The disc cutter is attached to the side surface of the drive unit main body. The disk cutter can be adjusted vertically and can be fixed easily. A diamond cutter is the most suitable material, and a disk size of 10 to 50 cm is suitable. 2 is a lifting mechanism, which is a wedge. Insert this tip into the lower surface of the sand-containing artificial grass to be cut. In the case of a large flat surface, you can insert a wedge into the artificial grass containing sand with a knife and insert the wedge. The artificial turf climbs up the slope of the wedge and is cut by a disc cutter, and the cut edge is separated from the wedge. The height of the wedge is a fulcrum 4 that supports the arm of the wedge.
The height can be adjusted by rotating the part. Three
The power unit drives the cutter and the wheels for self-propelled driving. The engine and the rotation transmission device are compactly installed inside. The method for cutting artificial sand containing sand of the present invention provides a very effective and easy treatment method when discarding an artificial grass structure that is extremely heavy due to sand inclusion, and the cutting treatment uses a combination of simple mechanisms. It is intended to provide a self-propelled sand-containing artificial grass cutter that can be easily operated.

EXAMPLES The present invention will be described in more detail with reference to examples.

Example 1 Nylon sand artificial turf was laid on a tennis court, and 11 years later, it was decided to replace it. Therefore, when discarding old artificial grass, we decided to cut the sand-containing artificial grass. The cutter for cutting was manufactured by hand by using the equipment shown in FIG. 1, and the blade of the cutter was a disk-shaped diamond cutter. Using this equipment, it cut into about 1 m square at a speed of 2 m / min. Cutting was carried out over a period of 2 days with a total length of about 1,000 m, but the cutting was extremely smooth and the sharpness of the diamond cutter did not deteriorate particularly during this period. The cut artificial turf could be compactly loaded on a pallet and then loaded onto a truck very easily, which was very popular with workers.

[0014]

As described above, the method for cutting artificial sand containing sand of the present invention can change the work of removing artificial grass, which has conventionally relied on the method of handling heavy objects, to the handling of lightweight pieces, and work in adverse environments. There is a great effect that the site can be comfortably improved and the surrounding environment is not adversely affected.
