Description

Automatic spreader for artificial turf {auto spreader for artificial turf}

The present invention relates to an automatic grass laying device for artificial turf, and more particularly, to an automatic grass laying device for artificial turf for automatically filling granule-shaped filler on the turf of artificial grass.

In general, artificial turf is formed of a carpet of artificial turf in the form of grass and is installed in an indoor garden where natural grass is impossible to grow, or in an outdoor area facing the north side of a high-rise building with extremely limited sunshine time, or emotionally beautiful scenery. It is installed indoors or outdoors for landscaping or landscaping. In addition, artificial turf is widely used as a substitute for natural grass that can protect the body of athletes exercising on the playground. Such artificial turf is transported in rolls and installed in a wide area such as a playground.

When explaining the installation process of the artificial turf in more detail, the worker carries the artificial turf in the form of a roll according to the grass layout (specifications and drawings), arranged in order on the ground and spread out in order. Then, the overlapped artificial turf and the edges of adjacent artificial turf overlap each other, and then, the overlapped edge is sewn and connected. In order to sew the artificial turf, two sewing machines, compressors, forklifts, tractors, air hoses and lead wires, eight carpet tongers, one sewing thread, one air hose, one line and sewing aid, and one forklift driver A total of 13 personnel, including transport personnel, are mobilized.

Here, the sewing process in more detail, in order to sew a grass pile of artificial turf so that the turf pile is not caught on the sewing line first, and then using the forceps so that the sewing line comes out uniformly. In the state that pulled artificial turf on both sides, move sewing machine in order toward sewing machine in order to sew. Then, when the whole sewing is completed, the reverse side is sewn again to perform the double sewing work, straightening the overlapping artificial grass straight and then ironing work using a roller so that the sewing line is not displayed.

Thus, when artificial turf is connected by sewing work, a line (fouling line, foreluner line, etc.) is attached to the artificial turf using a hot melt machine, and the granular filler is filled in the artificial turf. This filling process is completed by the first line work (1) the pile of artificial turf laid down with a brush, and (2) the bottom filling layer (silica layer) and the middle filling layer (1: 1) in the ratio of the filling material (2) After forming silica sand + rubber chip) and upper filling layer (rubber chip), and (3) suppressing the flow of upper filling layer (rubber chip) and fabbing so that the ball is not directed (work to make exposed pile into multiple strands) Is carried out.

Here, the upper, middle and lower filling layers described above (4) after the filler is evenly spread over the entire artificial turf using a sprayer, and (5) each filling layer using a brush so that the silica sand is evenly filled between the piles. (6) and flattened by scraping the upper part of the packed layer with a brush. At this time, the filling layer flow operation by the brush is performed every time the filler is laid to form each filling layer. This packed bed flow operation is typically repeated about 3 to 15 times for each bed. That is, the packed bed flow operation is repeated about 9 to 45 times when performed in three layers.

However, the above-mentioned filling material filling operation is not only very difficult to work because all the work is performed by a manual work by the operator, and there is a problem that the air is long because the above-described work steps (1) to (6) must be carried out without exception. In particular, the packed bed flow operation has a problem that the air is further extended because it has to be repeated several dozen times for each packed bed.

In addition, when the filling layer of artificial turf flows or scraps, the area of the artificial turf installed in the playground is large, so that many workers need to be mobilized. Since flattening is performed, there is a problem that the level of the filling layer is not uniform, and there is also a problem that the bristles are damaged by the brush.

The present invention has been made to solve the problems of the prior art as described above, while automatically standing the turf of the artificial turf lying while moving along the artificial turf installed on the ground and automatically filling the granule-shaped filler in the turf. The purpose is to provide an automatic spreading device for artificial turf that can be.

In particular, the turf of artificial turf can stand up to the wind pressure, and in addition to the acceleration of the filling of the filler to be filled in the turf to wind pressure, and moreover for artificial turf that can flow the turf filled with the filler to wind pressure The purpose is to provide an automatic spreading device.

In addition, another object of the present invention is to provide an automatic grass laying device for artificial turf that can adjust the filling amount of the filler to be filled in the turf.

In addition, it is possible to equalize the upper portion of the filler to a set height, and furthermore to provide an automatic laying device for artificial turf that can finally flatten the edge-side filling material accumulated by being pushed to the upper edge of the filler during the flattening process Another purpose.

The above object is an automatic laying device for artificial turf for placing a granule-shaped filler on the turf of artificial turf, comprising: a bogie moving on the artificial turf; A standing member installed on the trolley and providing a pressure to the turf side of the artificial turf lying thereon to stand the turf in a vertical state; And a hopper installed on the trolley together with the standing member and filling the filler with the filler and placing the filler on the turf standing up through the discharge port.

The standing member may be configured, for example, by setting air nozzles that vertically set the turf by injecting air into the turf.

The hopper further includes an acceleration air nozzle for injecting air into the discharge port to accelerate discharge of the filler.

The hopper may further include a damper having one end fixed to an inner surface of the discharge port; It is fastened to the hopper, while adjusting the opening amount of the discharge port while pressing and moving the damper; further includes a.

The present invention further includes a flow air nozzle for injecting air into the turf filled with the filler to flow the turf.

The present invention may further include a flat brush scraping an upper portion of the filler filled in the turf to flatten the upper portion of the filler.

The present invention may further include a roll brush for scraping the upper edge of the filler flattened by the flat brush and flattening the stacked filler by being pushed to the edge of the filler by the flat brush.

The present invention automatically stands up the turf of artificial turf on which the standing member is laid during the movement of the bogie, and fills the filler in the sod where the hopper stands, so that only one operator who drives the bogie can charge the filler in a wide area for a short time. have.

In addition, since the setting air nozzle ejects air to raise the turf, the damage of the turf generated by the brush can be prevented as in the prior art, and since the filler is discharged to the discharge port of the hopper by the accelerated air nozzle, the filler can be discharged quickly. In addition, the discharge port can be prevented from being blocked by the filler, and as the floating air nozzle sprays the air to flow the turf, the filler installed in the turf flows to reduce the air gap, thereby compactly filling the filler. In addition, it can be charged uniformly.

In addition, since the damper is moved by the adjustment screw to open the discharge port of the hopper, not only the amount of filling of the filling material can be easily adjusted, but also the height of the filling layer can be adjusted by adjusting the amount of laying.

In addition, the flat brush 180 is flattened by scraping the uppermost part of the filling layer when the trolley moves, so that the top of the filling layer can be automatically flattened immediately after the filling of the filling material. In addition, the roll brush has an edge 11a of the filling layer. Since the) side is continuously planarized, the top of the filling layer can be planarized to a more uniform level with certainty.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 are views showing the automatic laying device for artificial turf according to the present invention.

The automatic grass laying device 100 for artificial turf of the present invention is to vertically stand the turf 11 of the artificial turf 1 installed on the ground, and automatically install and install the filler 20 between the turf 11 that is standing. Device. The automatic grass laying apparatus 100 for artificial turf is composed of a bogie 110 and a hopper 140, and a standing member to be described later, as shown in FIGS.

The trolley 110 is configured to be movable by wheels 111 respectively provided at corner portions of the lower surface thereof. The truck 110 is provided with an engine 120 for driving. The engine 120 may be connected to the front wheel or rear wheel shaft of the trolley 110 so as to be power-transmitted by a chain or the like. In this case, the engine 120 may be implemented by a conventional internal combustion engine or a motor. In addition, the engine 120 may be connected to the front wheel or the rear wheel by a power transmission method (for example, a chain, a belt, a gear, etc.) of a conventional vehicle.

Therefore, the trolley 110 configured as described above may be moved by magnetic force on the artificial turf 1 installed on the ground.

The hopper 140 is installed on the upper surface of the bogie 110, the inside of the filler 20 made of granular silica sand and / or rubber chips is stored, the lower portion of the discharge hole 20 is discharged ( 141 is formed.

At this time, the filler 20 may be composed of a mixture chip or rubber chip made of silica sand or silica sand and rubber chips, depending on the layer is filled in the turf 11 of the artificial turf (1). For example, the hopper 140 is filled with a filler 20 made of silica sand chips when the filling layer to be filled is a lower filling layer made of silica sand chips, and when the filling layer is an intermediate filling layer made of silica sand chips and rubber chips. The filler 20 made of mixed chips is filled, and the filler 20 made of rubber chips is filled when the filling layer is an upper layer conductive layer made of rubber chips. That is, the type of the filler 20 is different depending on the type of the filling layer formed on the turf 11 of the hopper 140.

The hopper 140 has a damper 142 on the inner surface of the discharge port 141 to adjust the opening width, that is, the amount of the filler 20 discharged by adjusting the opening amount. As shown in FIG. 4, the damper 142 is bent in a substantially “Ｖ” shape and is installed to be long along the discharge port 141 of the hopper 140. At this time, the damper 142 is fixed to the inner surface of the hopper 140 as a fixing screw 143, the lower end forms a free end as shown. Accordingly, the damper 142 adjusts the opening width of the discharge port 141 while the lower end of the damper 142 moves back and forth in the hopper 140.

The hopper 140 is screwed to the adjustment screw 144, as shown in FIG. The adjusting screw 144 is in contact with one surface of the damper 142 as shown. The adjusting screw 144 is rotated to press the free end of the damper 142 to move to the inside of the hopper 140 or to return to the original position. That is, the adjusting screw 144 pushes the damper 142 while the protruding length of the hopper 140 is extended, and returns the damper 142 to its original position while the protruding length is reduced. At this time, the damper 142 returns to its original position by its own elastic force.

On the other hand, the above standing member is a member for providing a pressure to the turf 11 of the artificial turf 1 lying up to stand the turf 11 in a vertical state. For example, the standing member may be configured as a setting air nozzle 151 installed on one side of the hopper 140 as shown in an enlarged view of FIG. 3. The setting air nozzle 150 is connected to the compressor 130 installed on the upper surface of the trolley 110 to the side of the turf 11 laying the compressed air of the high pressure of the compressor 130 through the injection nozzle 151. Spray at high speed. Thus, the lying turf 11 is set vertically. Of course, the setting air nozzle 150 injects compressed air at a pressure that can stand vertically lying on the lawn 11.

The setting air nozzle 150 is preferably configured by mounting a plurality of injection nozzles 151 in the pipe. In addition, the setting air nozzle 150 has a center of the second slope, that is, 135 degrees based on FIG. 2 so that the injection nozzle 151 can vertically set the turf 11 toward the moving direction of the bogie 110. It is preferable to be inclined to an extent. In addition, the setting air nozzle 150 is preferably installed along the discharge port 141 of the hopper 140 in the width direction of the trolley 110 (the direction perpendicular to the traveling direction of the trolley) as shown in FIG. 3. .

On the other hand, the hopper 140 has an acceleration air nozzle 160 is installed therein as shown in FIG. As shown in FIG. 4, the accelerated air nozzle 160 injects the compressed air toward the discharge port 141 below. Therefore, the hopper 140 can not only discharge the filler 20 to the discharge port 141 quickly, but also can prevent the discharge hole 141 from being blocked by the filler 20 in advance.

In addition, the hopper 140 is provided with a flow air nozzle 170 having a spray nozzle 171 on the other side as shown in FIG. The floating air nozzle 170 is installed to be inclined such that the injection nozzle 171 is close to 90 degrees from the second slope with reference to FIG. The floating air nozzle 170 shakes the turf 11 filled with the filler 20 by spraying compressed air to the upper portion of the turf 11. Therefore, the filler 20 installed and filled in the turf 11 is evenly filled in the turf 11. That is, the filler 20 has a smaller pore as the turf 11 flows.

Here, the above-described flow air nozzle 170 sprays compressed air weaker than the above-described setting air nozzle 150. In particular, the flow air nozzle 170 injects compressed air with an intensity that can flow only the turf 11 while preventing the filler 70 from scattering.

On the other hand, the trolley 110, as shown in Figure 2, the plate-shaped flat brush 180 is installed behind the hopper 140. The flat brush 180 is fixed to the trolley 110 in a state in which rotation is impossible.

In addition, as shown in FIG. 2, the trolley 110 is provided with a rotary type roll brush 190 that is rotatable behind the flat brush 180. The roll brush 190 has a longer length in the width direction of the bogie than the flat brush 180, as shown in FIG.

As shown in FIG. 5, the flat brush 180 flattens the upper part of the filler by scraping the upper part of the filler filled in the turf 11 as shown in FIG. 5. As shown, the brush on the outer circumferential surface scrapes the filler edge 11a side of the artificial turf turf 11 to flatten the filler edge 11a side. In particular, the roll brush 190 finally flattens the filler 20 stacked by being pushed toward the edge 11a of the turf 11 by the flat brush 180.

Here, the roll brush 190 is connected to the engine 120 for driving the wheel 111 of the trolley 110 as a belt or a chain is rotated by the engine 120.

It describes the operation of the automatic grass laying apparatus for artificial turf according to the present invention configured as described above.

First, the artificial turf roll (not shown) wound in a roll form is laid on the ground of the playground to finish the line work, and then the artificial turf (1) of the artificial turf for each line through the trolley 110 (1) Do the laying work by moving along). That is, the automatic grass laying device 100 for artificial turf is opposite to the lying direction of the artificial turf turf 11 through the wheels 111 clouded by the engine 120 of the truck 110, as shown in FIG. Is moved in the direction.

At this time, the setting air nozzle 150 of the standing member is a high pressure on the grass 11 lying on one side of the hopper 140, that is, the front of the discharge port 141 through the spray nozzle 151 as shown in FIG. Blows compressed air at high speed. Therefore, the turf 11 is erected vertically by the wind pressure of the compressed air.

The hopper 140 installs the filler 20 in the turf 11 that is erected through the discharge port 141. In this case, the accelerated air nozzle 160 injects the high-pressure compressed air into the discharge port 141 inside the hopper 140 as shown in FIG. 4. Therefore, the filler 20 is installed in the turf 11 while being quickly discharged to the discharge port 141 without being blocked by the wind pressure of the compressed air.

Hopper 140 is a lower filling layer made of silica sand chips on the turf 11 while repeatedly performing three to 15 times laying work for each floor according to the filler layer characteristics of the turf 11 by the filler 20 and An intermediate filling layer made of mixed chips and an upper filling layer made of rubber chips are formed. At this time, it is preferable that the filler 20 is repeatedly installed to 2 mm or less at a time so that the turf 11 can be evenly filled. In addition, it is preferable that the intermediate filling layer is formed by mixing silica sand and rubber chips having a size of 14 to 30 of the US mesh standard. In addition, the upper filling layer is preferably installed with rubber chips of 10 to 14 sizes of the US mesh standards. Each of these filling layers is preferably filled in a volume ratio of 1: 2: 1, and the total filling amount is preferably filled at 75% or more with respect to the length of the turf 11.

Here, the above-mentioned hopper 140 is adjusted by the damper 142 is installed amount. At this time, the damper 142 opens the discharge port 141 of the hopper 140 while the lower end forming the free end moves by the rotation of the adjusting screw 144. Thus, hopper 140 lays out the filler 20 in the desired amount. Of course, the hopper 140 may adjust the height of the filling layer of the filler 20 by adjusting the amount of laying. That is, the filling layer is formed of a low height because the filling material 20 to be installed with the movement of the trolley 110 when the amount of installation of the hopper 140 is adjusted in a small amount, and the filling amount 20 when the amount of installation is largely adjusted. ) Is installed in large quantities, so the height is high.

On the other hand, the flow air nozzle 170 installed on the other side of the hopper 140 injects high-pressure compressed air at high speed to the turf 11 filled with the filler 20 through the injection nozzle 171. At this time, the turf 11 flows while shaking from side to side by the wind pressure of the compressed air. Therefore, the filler 20 filled in the turf 11 reduces the gap while being evenly charged.

On the other hand, the flat brush 180 flattens the upper portion of the filler 20 by scraping the upper portion of the filler 20 filled in the turf 11. Then, the roll brush 190 is finally flattened by scraping the upper portion of the filling material 20 that is pushed toward the edge 11a by the flat brush 180 while following the flat brush 180. Thus, the filler 20 is flattened to a set uniform height.

The automatic grass laying apparatus for artificial turf according to the embodiment of the present invention as described above automatically stands the grass wool 11 of the artificial turf 1 on which the standing member is laid during the movement of the bogie 110 and the hopper 140. Since the filling material 20 is charged to the standing grass wool 11, the filling material 20 can be charged for a short time in a wide area even with only one worker driving the truck 110.

In addition, since the setting air nozzle 150 injects air to stand up the turf 11, the damage of the turf 11 generated by the brush can be prevented as in the prior art, and the acceleration air nozzle 160 Since the filler 20 is discharged to the discharge hole 141 of the hopper 140, not only can the discharger 20 be quickly discharged, but the discharge hole 141 can be prevented from being blocked by the filler 20, and the flow air As the nozzle 170 injects air to flow the turf 11, the filler 20 installed in the turf 11 flows, thereby reducing the voids, thereby densely filling the filler 20. It can be charged evenly.

In addition, since the damper 142 moves by the adjustment screw 144 to open the discharge port 141 of the hopper 140, not only the amount of laying of the filling material 20 can be easily adjusted, but also by adjusting the amount of laying. The height of the packed bed can also be adjusted.

In addition, the flat brush 180 is flattened by scraping the uppermost part of the filling layer during the movement of the bogie 110, so that the top of the filling layer may be automatically flattened immediately after the filling of the filling material 20, and in addition to the roll brush ( 190 continuously flattens the edge 11a side of the filling layer so that the top of the filling layer can be flattened to a more uniform uniform height.
