Description

  The present invention repels and sucks up the sediment between the artificial turf, and separates and collects unnecessary powdery soil and reusable mesh sand from this sediment, and only the sorted mesh sand is used as new mesh sand between the grasses. The present invention relates to a hand truck for reducing and spraying separation sand that can be used for collecting and separating artificial sediment between artificial turf.

  In general, in artificial turf coats (omni coats) and artificial turf grounds with good water permeability, the sliding resistance when dry and wet by rain, water spray, etc., and the normal turf coat sliding condition should be made almost equal. In order to reduce the burden on the legs and legs of the athlete without affecting the bounce and rolling of the ball when playing tennis, etc. The fine sand such as crushed sand obtained by pulverizing olivine is uniformly sprayed and filled.

  This fine sand is generally a magnesium-rich, rounded, irregular appearance with a smooth texture consisting of a group of magnesium-iron silicate minerals that crystallize in an orthorhombic system. It usually has a simple crystal phase, and is a collective form of double cones, column faces, and table faces, gloss is glassy, color is olive green, hardness is Mohs hardness meter 6.5-7, specific gravity is 3.3 In 3.4, it increases as the iron content increases. In general, the filling amount of the sand between the turf is uniformly distributed to a height of 90% (about 17 mm) of the height of the artificial turf (about 19 mm).

  However, in all-weather courts and artificial turf grounds laid with artificial turf, a large amount of unnecessary powdery soil and dust fly and accumulate between the artificial turf from surrounding fields, unpaved roads and wilderness, etc. Cause clogging phenomenon, clogging phenomenon in the open granulated ascon under artificial turf, worsening drainage, and frequent use of artificial turf due to repeated usage The dust becomes concrete and hardens, and the coat itself becomes hard like clay and an untouched coat, which causes an essential and big problem that it is no longer usable as a loan coat.

  There are various proposals for solving the problem of such an artificial turf coat. For example, as in Patent Document 1 below, the height can be adjusted in the horizontal direction, and the cylindrical shape has protrusions on the outer peripheral surface. Or using a traveling machine provided with a cylindrical rotating body, while propelling the protrusions of the rotating body against the sand layer of the artificial grass with sand, running the traveling machine on the field of artificial grass with sand, A method for collecting sand-containing artificial lawn is known in which sand is removed and removed with a vacuum cleaner, and then the artificial lawn is peeled off from the ground and removed.

Separately from this, as shown in Patent Document 2 below, a nozzle that injects water obliquely downward and rearward with respect to the ground is provided at the front opening of the box-type machine frame that can be traveled. The sand and water that has been scooped up by the scooping member that scoops up the sand that has been blown up from the opening together with the water is stored in the storage chamber in the machine frame, and the water in the storage chamber is sucked up and circulated to the nozzle. Lawn sand removers equipped with a pump are also well known.
JP 2001-336111 A Japanese Patent Publication No. 6-97885

  In the conventional example of the above-mentioned Patent Document 1, when removing the artificial grass containing sand laid on the ground on which a large amount of unnecessary powdery soil has been deposited, the soil on which a large amount of powdered soil has accumulated is removed by vacuuming between the artificial turf in the ground laid state. After that, this removed artificial turf is peeled off from the ground again to remove and collect the artificial turf with sand, and in this conventional example, only the surface layer between the turf is the part where a lot of powdery soil is accumulated. From the viewpoint that the lower layer sand has no powder soil and can be reused, the artificial turf in which the lower layer sand remains after removing only the surface layer sedimentary soil from the artificial turf laid on the ground in advance. This is a method for collecting artificial lawn with sand that can be peeled off and collected again.

  The conventional example of Patent Document 2 is a spray width of a separately prepared mesh sand spreader that is used after removing the mesh sand when repairing damaged areas such as artificial grass and golf course green. This is a lawn sand remover used to scoop up and remove pre-sealed sand together with water.

  Therefore, each of the conventional examples only removes the sand filled between the turf at the time of the artificial turf facility such as an artificial turf coat or a ground and a large amount of dust and dirt accumulated over time between the turf, Collect and collect earth and sand containing unnecessary powdery soil and reusable mesh sand, and only reusable separated mesh sand cannot be reduced and sprayed again between the court and ground grass as spray sand. Requires a total of two traveling equipment and other equipment for spraying special sand, which is cumbersome, inconvenient and cumbersome in all aspects of equipment management, transportation distribution, sales purchase, use inspection, etc. In addition to its poor nature, there is an essential and big problem that it is extremely disadvantageous in terms of price.

  In order to eliminate the problems of each of the conventional examples, after passing through a sand and sand suction machine that sucks the accumulated sediment between artificial turf splashed with a roll-shaped rotating brush from the hood, and a lower pipe of a T-shaped pipe connected to the discharge port A dust separation filter for passing the dust in the earth and sand provided in the pipe together with the exhaust flow, an exhaust filter bag for storing powder in communication with the rear pipe, and the separation sand blocked by the filter through the lower pipe After that, a skirt for preventing dust splattering around the opening to be sprayed with the remaining exhaust flow and a prime mover for driving the rotary brush to rotate are mounted on a single carriage, and the sediment deposited between the artificial turf is collected. There is not yet a handcart that can reduce and dispose of the sorted sand at the place where it is collected and removed.

  This invention separates and collects only the reusable separated sand between the artificial grass while separating and collecting the earth and sand containing a large amount of unnecessary powdered soil and the reusable sand with the equipment mounted on one truck. The purpose is to enable reduction spraying as new mesh sand.

  The object of the present invention described above is provided in the rear pipe through the earth and sand suction machine for sucking the sediment between the artificial turf repelled by the roll-shaped rotating brush from the hood and the lower pipe of the T-shaped pipe connected to the discharge port. A dust sorting filter that allows the dust in the soil to pass together with the exhaust flow, a dust filter exhaust filter bag that is disposed in communication with the rear pipe, and a fraction that flows down with the remaining exhaust flow in the lower pipe before the filter. This can be achieved by mounting a skirt for preventing the scattering of the sand from being scattered and a prime mover for rotationally driving the rotating brush on each cart.

  Further, the object of the present invention is to provide a sediment suction machine for sucking artificial turf accumulated sediment repelled with a roll-shaped rotating brush from a hood, and a T-tube lower pipe connected to the discharge port in a rear pipe. A dust sorting filter that allows the dust in the soil to pass together with the exhaust flow, a dust filter exhaust filter bag that is disposed in communication with the rear pipe, and a fraction that flows down with the remaining exhaust flow in the lower pipe before the filter. It could also be achieved by mounting a diffusion box for the mesh sand, a skirt for preventing dust scattering provided around the lower opening, and a prime mover for rotationally driving the rotating brush, respectively.

  More specifically, a roll-type rotating brush that repels and removes the sediment accumulated between the artificial turf on the front side of the handcart is pivoted horizontally, and the hood collects the repelled sediment by this brush. After projecting from the hood, the earth and sand protruding from the hood are piped so as to be sucked by the earth and sand suction machine arranged at the front part of the shelves of the carriage, and then passed through the lower pipe of the T-shaped pipe connected to the rear outlet. A fine mesh powder separation filter that allows only unnecessary powdery soil and exhaust flow in the soil to be separated and passed through the pipe, and reusable mesh sand larger and heavier than the powdery soil is separated into the lower pipe together with the remaining exhaust flow. An exhaust filter bag for collecting and collecting unrequired dust is collected and connected to the rear pipe that has passed through this filter, while the reusable sand after separation that flows down the lower pipe in front of the filter is disposed in the lower part. Open diffusion box inside After removing the sediment from the mesh sand spraying opening in the mesh skirt for preventing dust scattering suspended at the bottom of the cart while diffusing a large amount of mesh sand by colliding with the remaining exhaust flow and making it turbulent It is configured to be able to reduce and spread as new sand between the turf, and an electric motor for rotationally driving the rotating brush and the earth and sand suction machine is mounted on the handcart, and a power supply cord to the electric motor is connected from the carriage It was also possible to achieve it by extending.

  In order to rotate the rotating brush and the earth and sand suction machine, a prime mover such as an internal combustion engine that does not require a power supply cord may be used, and the hood, earth and sand suction machine, T-shaped tube, dust classification filter, and exhaust A pair of right and left filter bags may be individually arranged. In this case, a pair of left and right sewable sands flowing through the pair of left and right T-shaped pipes in front of the filter together with the remaining exhaust flow. A large amount of sand is further blasted by opposing jetting from both sides into the diffusion box through a flexible pipe, and causing the above-mentioned sand to collide with the exhaust flow in front of each other in the diffusion box to cancel the flow velocity. The handcart may be provided with a pair of left and right front wheels and a pair of left and right caster rear wheels, and the skirt may be formed of a flexible material.

Since the present invention employs the above-described means, the following effects can be obtained.
According to the first to fourth aspects of the present invention, the apparatus for repelling and removing the artificial interstitial soil with a large amount of powdered soil by repelling, removing unnecessary powdered soil from the suctioned sand and sand. Since one handcart is equipped with equipment that separates and collects available sand, and equipment that reduces and recycles only reusable sorted sand as artificial sand between the artificial turf that has been removed. By simply moving a handcart to the artificial turf surface, it separates and removes the dust in the sediment between the artificial turf and the reusable mesh sand, while removing only the reusable mesh sand. The new artificial sand between the removed artificial turf can be reduced and sprayed with good workability, it is easy to handle in all aspects such as equipment management, transportation distribution, sales purchase, use inspection, etc. There is an effect.

  In the invention of claim 5 according to the present invention, in addition to the above-mentioned effects, the hood, the earth and sand suction device, the T-shaped tube, the powder soil separation filter, and the exhaust filter bag are individually arranged on the left and right sides, respectively. The earth and sand deposited on the sand can be removed as widely as possible, and the effect of widening the reduction spread of the mesh sand can be added, and the pair of left and right T-shaped tubes as in the invention of claim 6 of the present invention. The separated sand that flows down the lower pipe is jetted from both sides into the diffusion box through the pair of left and right flexible pipes together with the remaining exhaust flow, and the above-mentioned sand is collided with the exhaust flow in front of each other in this diffusion box. By turbulent flow while canceling out the flow rate, a large amount of sand and exhaust flow can be diffused better, and the sand is further improved between the artificial turf with earth and sand removed. The effect of reducing spraying It could be added to.

  In the invention of claim 7 in the present invention, since the hand cart is provided with a pair of left and right front wheels and a caster rear wheel, it is possible to add an effect that the traveling direction of the hand cart can be easily changed while grounding the front wheel, Further, if the skirt is formed of a flexible material as in the invention of claim 8, the lower side of the skirt can rub the turf surface flexibly, so that one of the factors hindering the progress of the handcart can be reduced and the turf surface can be reduced. The effect of not hurting can be added.

  As an example of the best basic form of the present invention, as shown in FIGS. 1 to 4, earth and sand that sucks from artificial turf accumulated sand repelled by a roll-shaped rotating brush 2 pivotally supported on a carriage 1 from a hood 3. Suction machine 4, dust filter 6 that passes through the lower pipe 5 </ b> A of the T-shaped pipe 5 connected to the discharge port 4 </ b> A and passes through the dust in the earth and sand provided in the rear pipe 5 </ b> B together with the exhaust flow, and the rear pipe 5 </ b> B. 2 and the rotation around the opening 10 as shown in FIG. 2 for spraying the fractionated sand blocked by the filter 6 together with the remaining exhaust flow through the lower pipe 5A. The artificial skirt 9 according to the present invention is provided by mounting the skirt 9 for preventing the scattering of sand provided around the brush 2 and the motor M for rotationally driving the rotating brush 2 and the earth and sand suction device 4 respectively on one carriage. Reduction and spraying of fractionated sand that can also be used for recovery of interstitial sediment. I was able to configure the truck press. When there is a lot of accumulated powdered soil, a lower open diffusion box 8 is provided between the lower pipe 5A and the opening 10 for diffusing the mesh sand together with the exhaust flow.

  Specifically, as shown in FIGS. 1 to 4, the earth and sand accumulated by elastically entering the artificial turf on the front side of the hand cart 1 having a width of about 1 m is splashed forward and removed. An electric roll-shaped rotating brush 2 having a diameter of about 25 cm and a width of about 1 m is pivotally supported by a pivot 2A, and a pair of left and right front thin hoods 3 for collecting earth and sand splashed by the brush are directed forward to the cart 1 Flexible so that the earth and sand protruding from each hood 3 can be sucked by the left and right earth and sand suction machines 4 with built-in motors (electric motors and engines) arranged in front of the shelf 1A of the cart 1 Although the pipe P is used as the earth and sand suction machine 4, a general crushed stone suction machine which is usually called “dust collector” at the construction site is used as the earth and sand suction machine 4 in the present invention.

  Next, as shown in the respective drawings, in the pair of left and right rear pipes 5B through the lower pipe 5A of the T-shaped pipe 5 respectively connected to the discharge ports 4A of the pair of left and right earth and sand suction machines 4, about 20 Only about 80% unnecessary dust and about 50% exhaust flow are separated and passed, and about 80% of the reusable sand that is larger and heavier than the powder soil has about 50% remaining exhaust flow. A fine mesh perforated disk, a tough round wire mesh, or a mesh tray, which is separated and flowed down into the lower pipe 5A, is vertically installed with a powder soil sorting filter 6 having a diameter of about 12 cm. An exhaust filter bag 7 called a normal bag filter that collects and collects unsorted powder is provided in communication.

  On the other hand, the mesh sand flowing down in the lower pipe 5A of each T-shaped pipe 5 in front of the filter 6 is jetted oppositely from the holes on both sides into the diffusion box 8 through the flexible pipe P together with the remaining exhaust flow. In this diffusion box 8, the above-mentioned sand is collided with the exhaust flow in front of each other to make a turbulent flow while canceling out the flow velocity, thereby diffusing a large amount of sand and spreading the bottom of the cart 1 in the above figures. From the mesh sand spraying opening 10 which is widely opened in the rubber flexible skirt 9 suspended in the manner described above, the diffusion flow velocity is further reduced so that it can be sprayed downward. The weak exhaust turbulence is caused by the lower side of the skirt 9 and the turf. By letting it escape through the gap with the surface, it could be configured to be reduced and sprayed as new eye sand between the turf after removing the sediment.

  However, when there is little dust in the sediment deposited between the artificial turf, even if the rotating brush 2 and the sediment suction machine 4 are rotated weakly, the classified sand while removing the soil in the sediment. In this case, the diffusion box 8 can be omitted, and an opening 10 for directly spraying the separation sand blocked by the filter together with the remaining exhaust flow through the lower pipe as shown in FIG. 1 is provided, and a skirt 9 for preventing sand scattering is suspended around the periphery thereof as shown in FIG.

  Further, in order to rotationally drive the rotating brush 2 and the earth and sand suction machine 4, an electric motor M is mounted on the carriage 1 as shown in the above drawings, and a power feeding cord to the electric motor is extended from the carriage 1 to artificial grass. The rotary brush 2 and the earth and sand suction device 4 may be driven to rotate by an internal combustion engine that does not require a power supply cord, or connected to a commercial power source installed at a court management office or the like.

  In addition, the part shown by the code | symbol 1B in each said figure is the hand handle projected from the rear part of the trolley | bogie 1, the part shown by the code | symbol 1C * 1D is the front wheel and caster rear wheel of the trolley | bogie 1, and the part shown by the code | symbol P is about 12 cm in internal diameter. The portion indicated by the reference numeral B is a transmission belt.

  Since the present invention is configured as described above, when using this, first, whether the artificial turf interstitial sand is dry and smooth, randomly inspected with a hand-held brush, If the interstitial earth and sand are dry and smooth, the rotary brush 2 and the earth and sand suction machine 4 are driven to rotate by the electric motor M, and then the hand handle 1B protruding from the rear of the hand carriage 1 is provided. When the carriage 1 is pushed forward, the earth and sand accumulated between the artificial turf can be removed by repelling forward with the roll-shaped rotating brush 2 pivotally mounted on the front side of the carriage, and the earth and sand repelled by the brush 2 can be removed. While collecting with a pair of left and right hoods 3, the earth and sand protruding from each of the hoods 3 can be sucked with a pair of left and right earth and sand suction machines 4 arranged in front of the shelf 1 </ b> A of the carriage 1.

  Simultaneously with this suction, a dust sorting filter is vertically installed in a pair of left and right rear pipes 5B through a lower pipe 5A of a pair of left and right T-shaped pipes 5 respectively connected to the discharge ports 4A of the pair of left and right soil suction machines 4. 6 allows only about 20% of the undesired dust and about 50% of the exhaust flow in the earth and sand to be discharged into the exhaust filter bag 7 to collect and collect the undesired dust, and recycle larger and heavier than the dust. About 80% of the sand in the available earth and sand is bounced off by the dust classification filter 6 and flows down into the lower pipe 5A together with the exhaust flow of about 50% before that.

  The sorted sand that flows down is jetted from the holes on both sides into the diffusion box 8 through the flexible pipe P together with the exhaust flow of about 50%, so that the sand is exhausted in the diffusion box 8. A large amount of mesh sand can be diffused by causing it to collide with each other in front of each other and canceling the flow velocity, thereby diffusing a large amount of the mesh sand. From the opened mesh sand spraying opening 10, it was possible to further reduce the flow rate and to diffuse a large amount of mesh sand, and to reduce and spray a large amount of mesh sand between the artificial turf after removing the sand and sand with the rotating brush with good workability.

  When the amount of dust in the sediment deposited between the artificial turf is as low as about 10%, even if the rotary brush 2 and the sediment suction machine 4 are rotated with the operating rate reduced to about 60%, the amount in the soil is small. About 90% of the fractional sand in the earth and sand can be reduced and dispersed while removing the powdery soil. In this case, the grain sand separated by the filter 6 passes through the lower pipe 5A together with a weak exhaust flow remaining in the carriage. 1 can be directly sprayed downward between the artificial turf from the two openings 10 formed as shown in FIG.

  In the above description, an example in which the hood 3, the earth and sand suction machine 4, the T-shaped pipe 5, the dust classification filter 6 and the exhaust filter bag 7 are individually arranged on the left and right sides is described. When the amount of the powdered soil is as small as about 10%, the hood 3 in the present invention is made to have a rotating brush width, and a single earth and sand suction machine 4, a T-shaped tube 5, a powdery soil separation filter 6, and an exhaust filter bag 7 -Using only the diffusion box 8, while removing the sediment accumulated between the artificial turf, it is possible to disperse about 90% of the fractional sand in the soil between the artificial turf that has already been removed. In this case, the separation sand that flows down in the single lower pipe 5A is collided with the exhaust air flow of the remaining 50% from the hole on one side of the diffusion box 8 which is open to the opposite inner surface to reduce the flow velocity. A large amount of eyes of about 90% in the sediment deposited between artificial turf by flowing The can be better spread, fractionated eyes sand was reduced spread between turf after sediment removal from the eye sand spraying openings 10 of the carriage together with the exhaust stream weakened above.

  In addition to the artificial turf sedimentation sand removal hand truck, in addition to the artificial turf sedimentation sand removal site, for example, the sand collection / recovery separation sand particle reduction spray that is deposited on the sand before the green of the golf course, etc. It can also be used as a hand cart.
