Description

TECHNICAL FIELD The present invention relates to a maintenance device for artificial turf laid on a ground or the like.

When artificial turf laid on a ground or the like is used for a long period of time, piles may lie down or become buried in fillers such as rubber chips and sand due to tread pressure and aging deterioration. In addition, moss, mold, and mites can grow on the artificial turf, making it unsanitary. In addition, the filling material hardens and causes clogging, and debris such as pile scraps, hair, cloth scraps, paper, bird droppings, grass, and wood chips are mixed between the piles, resulting in puddle formation.

For this reason, artificial grass needs regular maintenance. For example, in Patent Document 1, a ferromagnetic material is used as part of the filling material, and a magnetic field is applied to the artificial turf to agitate the filling material and loosen hardening.

JP-A-10-237815

Of the above problems, hardening of the filler can be prevented by using a ferromagnetic material as the filler, but other problems cannot be solved.

FIG. 3 is an explanatory diagram of the state of the artificial turf after maintenance indicated by the circled portion B in FIG.

Hereinafter, the maintenance device 10 for the artificial turf 60 of the present invention will be described with reference to the drawings.

The artificial turf 60 is laid on the ground 70 as shown in FIG. 2 and 3, the artificial turf 60 is formed by planting piles 62 on a base cloth 61. Between the piles 62, rubber chips, cork chips, urethane (resin) chips and sand (Fig. A filling material 63 such as indicated by a middle numeral 64 and referred to as "rubber chips, sand grains, etc." is filled. The artificial turf 60 has been used for a long time, and as shown in the encircled portion A in FIG. Garbage 80 and 81 such as feces, grass, and pieces of wood adhere to or become entangled with the artificial turf 60. - 特許庁Also, the filling material 63 is wavy.

Such an artificial turf 60 requires maintenance to raise the ends of the piles 62, remove the dust 80 and 81, and even out the wavy filling material 63.例文帳に追加

The maintenance device 10 for the artificial turf 60 of the present invention is designed so that the above maintenance can be carried out by equipment mounted on one carriage 12 .

1, the maintenance device 10 is configured by mounting a rake portion 20, a sweeper portion 30 and a brush portion 40 on a truck 12. A coupler 13 is attached to the front end of the truck 12. can be connected to a tractor (not shown).

The carriage 12 is equipped with rollers 14 in the front and rear, and can run on the artificial turf 60 by being pulled by a tractor (running rightward in FIG. 1). The height of the rollers 14 can be adjusted with respect to the carriage 12, so that the height of the rake portion 20 and the like with respect to the artificial turf 60 can be adjusted as appropriate.

<Rake part 20>
A rake portion 20 for plowing up the pile 62 is formed at the front end of the carriage 12 . The rake portion 20 is formed long in the width direction of the carriage 12, and is configured by arranging a plurality of claws 21 extending downward in the width direction as shown in FIG. The rake part 20 is configured to receive power from the drive shaft 50 of the tractor and vibrate left and right (the power transmission mechanism is not shown). In the illustrated embodiment, the claw 21 once extends rearward from the frame 22 of the rake portion 20, and the tip thereof is bent downward. As a result, the claws 21 can be bent in the front-rear direction, so that the claws 21 can be prevented from sticking into the artificial lawn 60 and being damaged when the truck 12 is driven. In addition, it is desirable that the rake portion 20 can swing up and down.

<Sweeper part>
Behind the rake section 20, a sweeper section 30 having a suction mechanism 31 for sucking dust 80 and 81 is provided. In this embodiment, the sweeper part 30 is provided with a rotating brush 35 below the sucking mechanism 31, and the rotating brush 35 scrapes up the dust 80, 81 and the rubber chips, sand grains, etc. Of the collected dust 80 and 81, only the relatively light dust 80 is vacuum-sucked by the suction mechanism 31. - 特許庁Of the dust 80 and 81 raked up by the rotating brush 35, relatively heavy dust 81, rubber chips, sand grains and the like 64 are not sucked up by the sucking mechanism 31, but are moved to the sieve behind the rotating brush 35 by their own weight. It is sieved in the part 38 and the dust 81 is recovered.

First, the rotating brush 35 will be described. The rotating brush 35 has a shaft portion 35a that is elongated in the width direction of the carriage 12 and is journalled, and a brush 35b that is planted on the peripheral surface of the shaft portion 35a. The shaft portion 35a is linked to a joint means 37 provided at the front end of the carriage 12 by a power transmission mechanism comprising sprockets 36, 36 and a chain 36a. The joint means 37 is connected to the drive shaft 50 of the tractor and allows the shaft portion 35a to rotate. It is desirable that the power transmission mechanism has a clutch mechanism so that the rotation direction of the rotating brush 35 can be switched between normal and reverse.

The rotating brush 35 rotates a directional brush 35b along the running direction of the truck 12, as indicated by an arrow in the figure. As a result, the rotating brush 35 scrapes up the dust 80 and the like backward.

The suction mechanism 31 is arranged above the rotating brush 35 . The suction mechanism 31 can be exemplified by a vacuum motor 32 having a suction port 32 a directed toward a rotating brush 35 . The vacuum motor 32 can be a reversed blower, for example. A dust case 34 is placed on the carriage 12 , and the dust case 34 is connected to a discharge port 32 b of the vacuum motor 32 by a pipe 33 .

A sieve portion 38 is provided behind the rotating brush 35 . The sieving unit 38 is illustrated as two-stage sieves 38a and 38b. The upper sieve 38a is desirably arranged to vibrate back and forth by receiving power from the drive shaft 50, for example (the power transmission mechanism is not shown). As a result, even clumped dust 81 can be broken up to some extent. The lower sieve 38b screens the dust 81, rubber chips, sand grains, etc. 64 that have passed through the upper sieve 38a. The rear end of the upper sieve 38a is flat so that the upper sieve 38a does not clog and overflow. The meshes of the sieves 38a and 38b are preferably coarse enough to allow rubber chips, sand grains, etc. 64 to pass through, but not to allow dust 81 such as relatively large pieces of wood to pass through.

<Brush part 40>
A brush portion 40 is formed at the rear of the carriage 12 to straighten the tip of the pile 62 and level the filling material 63. - 特許庁The brush portion 40 has a brush frame 42 arranged behind the carriage 12 , and a brush 41 is planted from the brush frame 42 toward the lower side of the carriage 12 . The brush part 40 is desirably arranged on the carriage 12 so as to be vertically swingable.

A maintenance method for the artificial turf 60 by the maintenance device 10 configured as described above will be described.

As shown in FIG. 2, the artificial turf 60 that requires maintenance has fallen piles 62, has dust 80 and 81 adhering to it, and has hardened filler 63 and is wavy. ing. The square pieces of garbage indicated by reference numeral 80 are pieces of relatively lightweight pile 62, hair, pieces of cloth, paper, bird droppings, grass, leaves, small pieces of wood, and the like. Triangular dust indicated by reference numeral 81 is relatively large and heavy dust such as large pieces of wood such as twigs and wires. Reference numeral 64 denotes rubber chips, sand grains, and the like that constitute the filler 63 .

Then, the coupler 13 of the maintenance device 10 is attached to the tractor, and the joint means 37 is connected to the drive shaft 50 . Then, the tractor is run on the artificial turf 60 to pull the maintenance device 10. - 特許庁

In the maintenance device 10 , first, the claws 21 of the rake portion 20 penetrate between the piles 62 of the artificial turf 60 and rake the piles 62 . As a result, the dust 80, 81, rubber chips, sand grains, etc. 64 buried or entangled between the piles 62 come out from the piles 62.例文帳に追加In addition, it is possible to loosen the lumped filler 63 . By laterally vibrating the rake portion 20, the pile 62 can be loosened more efficiently, and the dust 80 and the like can be raised.

By further running the tractor, the sweeper section 30 passes over the dust 80, 81, rubber chips, sand grains, etc. 64 floated on the pile 62. - 特許庁Since the sweeper section 30 has a rotating brush 35 that is rotated by the drive shaft 50 of the tractor, the rotating brush 35 sweeps out the dust 80, 81, rubber chips, sand grains, etc. 64. FIG. As indicated by the arrow in FIG. 1, the rotating brush 35 rotates along the direction of travel, thereby raking up dust 80, 81, etc., backward. Among the scraped dust 80 , 81 , rubber chips, sand grains, etc. 64 , the dust 80 that is relatively light is sucked by the suction mechanism 31 and collected in the dust case 34 .

Relatively heavy dust 81 , rubber chips, sand grains and the like 64 that are not sucked by the sucking mechanism 31 fall off the rotary brush 35 and onto the sieve portion 38 due to centrifugal force and gravitational action. Since the upper sieve 38a of the sieve unit 38 is vibrated back and forth by the drive shaft 50, even if the dust 81 is clumpy, it can be broken up. Large dust 81 that cannot pass through the mesh of the upper sieve 38a remains on the upper sieve 38a. On the other hand, rubber chips, sand grains, and the like 64 pass through the upper sieve 38a, drop into the lower sieve 38b, pass through the lower sieve 38b, and return to the artificial turf 60. In this embodiment, since the upper sieve 38a is vibrated, clogging of the upper sieve 38a is less likely to occur. Since the dust falls from the rear end of the sieve 38a to the lower sieve 38b, much dust 81 does not accumulate on the upper sieve 38a.

The rotating brush 35 also has the effect of raising the tip of the pile 62 .

The artificial turf 60 from which dusts 80 and 81 have been removed by the sweeper section 30 is then leveled by the brush section 40 . The surface of the artificial turf 60 is brushed by the brush portion 40, and the tips of the piles 62 are raised and trimmed as shown in the enlarged view 3 showing the circled portion B of FIG. Also, the filling material 63 is leveled.

By running the maintenance device 10 over the entire surface of the artificial turf 60, the maintenance of the artificial turf 60 is completed. The artificial turf 60 whose maintenance has been completed has the dust 80 and 81 removed, the ends of the piles 62 stand up, and the filler 63 is evenly leveled.

Although the maintenance of the artificial turf 60 is completed as described above, it is desirable to perform finishing maintenance in order to further align the piles 62 . For the finishing maintenance, the rotating brush 35 is rotated in the opposite direction to the direction indicated by the arrow in FIG. As a result, the artificial grass 60 can be finished in a neat state in which the tips of the piles 62 stand up and the grains are aligned.

In the present invention, the rake part 20 and the brush part 40 are arranged on the carriage 12 so as to be able to swing up and down, and are pressed against the artificial turf 60 by their own weight. The part 20 and the brush part 40 will not damage the artificial turf 60, and the rake part 20 and the brush part 40 will not be damaged.

In addition, according to the maintenance device 10 of the present invention, the rake section 20, the sweeper section 30 and the brush section 40 can be mounted on one carriage 12, so that the number of trucks to be transported can be reduced, which is environmentally friendly and transports Cost can be reduced. Furthermore, only one tractor is required to pull the maintenance device 10, and the rake part 20, the sweeper part 30, and the brush part 40 do not need to be individually mounted on the tractor, and the tractor can be moved only once. Efficiency can also be increased.

The above description of the embodiments is for the purpose of explaining the present invention, and should not be construed as limiting the invention described in the claims or narrowing the scope. Further, each component of the present invention is not limited to the above-described embodiment, and of course various modifications are possible within the technical scope described in the claims.
