Abstract

PURPOSE: To quickly and easily pack sand between artificial grass blades by arranging on the artificial grass blades a retaining plate whose front and rear are warped, and putting the retaining plate into longitudinal sliding and reciprocating motion while it is pressed downward. CONSTITUTION: Sand 2 is supplied into an opening in artificial grass blades 1 to form unevenly supplied portions. Under this condition the lower surface of a retaining plate 3 is brought into contact with the upper surface of the sand 2 and pressed downward and the retaining plate 3 is put into longitudinal reciprocating and sliding motion while pressed. Then warped front and rear parts 3', 3" supply the sand 2 to the base of the grass blades 1. Therefore, the sand 2 can be quickly and easily packed between the grass blades 1.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method and apparatus for packing sand into artificial turf.

``Prior Art'' Conventionally, artificial turf that is laid on sidewalks at golf courses, tennis courts, gateball fields, etc. is made by densely planting relatively strong artificial turf leaves made of synthetic resin on the top surface of the sheet, and the length of the turf leaves is It is used by packing sand between the grass leaves to a thickness of about 18 cm and exposing about 2 cm of the grass leaves above the packed sand. However, the sand needs to be spread onto the top of the densely planted artificial turf leaves using a scattering machine, and then packed densely and evenly into the turf leaves. This packing work is not easy and requires skilled labor and a long time.

``Problems to be Solved by the Invention'' The present invention seeks to provide a method and apparatus for quickly, uniformly and densely packing sand into the densely planted grass leaves without requiring any skill.

``Means for Solving the Problems'' The present invention provides a method for supplying sand to the artificial grass leaves that have been laid down, placing a holding plate with the front and rear sides bent in a 9-shape on the artificial grass leaves, and moving the holding plate downward. The artificial turf sand filling method and its device are characterized in that the pressing plate is slid back and forth in the pressed state at L1.

"Operation" Therefore, the synthetic resin artificial grass leaves 1 densely planted on the sheet 1 are tilted to one side by the scraper 26, and the upright grass leaves 1 and the fallen grass leaves 11a and 11a are tilted to one side.
When sand 2 is supplied to the opening, the sand 2 is filled into the opening, and other sand 2 is deposited on the upright grass blades 1, forming an uneven supply. In this state, when the lower surface of the presser plate 3 is brought into contact with the upper surface of the sand 2 and pressed downward, and slid back and forth in the front and back directions while in the suppressed state, the sled-like front and rear portions 3.3 will tilt one upright grass blade back and forth. Sand 2 is supplied to the base of the grass blade 1 which is tilted.

Also, the sand under the central lower surface of the holding plate 3 is pressed and packed into the base of the two grass blades 1. Three of these presser plates are placed in parallel in the left and right direction.
The ILI holding plates 3.3 alternately slide forward and backward, and in this state the left and right horizontal rod holding plates 3 can be moved forward at a constant speed whether on a slope or on a flat surface.

"Embodiment" A drive wheel 5 and a steering wheel 5 are provided on a chassis 6, and a machine platform 7 is supported at the bottom of the chassis 6 so as to be movable up and down along a vertical inner guide 13. (Fig. 1). A plurality of back-and-forth reciprocating sliding plates 8 are arranged side by side in the left-right direction on the machine base 7, and each has a horizontal guide guide 15.
．． 15 (Figure 2). and the adjacent sliding plate 8
．． A drive device 9 is provided at the rear of the sliding plate 8.8 for sliding the plate 8 alternately forward and backward. This drive device 9 includes a left and right drive shaft 9 rotated by a hydraulic motor 9, and eccentric cams 9a with a psychic phase difference of 180 degrees installed alternately on the drive shaft 9.
s9b and the cam 9a19b with the force of the spring 9c.
is provided so as to pull the sliding plate 8 to the rear of the machine base 7.

The front part of the sliding plate 8.8 has a horizontal axis 1 in the left and right direction, respectively.
The base of the metal fitting 11 is pivotally supported by the metal fitting 11, and the metal fitting 11 is extended forward of the machine base 7, and further downwardly bent into a shape.
The lower end of the metal fitting 11 is connected to the middle of the holding plate 3, which has the front and rear parts 3.3 bent into a warped shape. As shown in FIGS. 4 and 5, this presser plate 3 may be supported on a metal fitting 11 so as to be movable in the left-right direction around a horizontal axis 11 in the front-rear direction. A downward pressing tool 12 is formed between the shaped metal fitting 11 and the left-right horizontal rod 16 provided on the machine base 7, with a spring 12' interposed therebetween for pressing the metal fitting 11 downward. A gasoline engine 17 is mounted on the chassis 6, and a hydraulic pump 18 driven by the engine 17 is provided. By manually operating the interposed L1 i! valve 13, the rotation of the drive wheel 5σ can be kept constant and the traveling speed can be kept constant on a gently sloped surface.

During traveling, the adjacent presser plates 3.3 are alternately slid forward and backward by rotation of eccentric cams ga and gb with a phase difference of 180 degrees. The lifting and lowering of the machine base 6 is performed by a worm 20, a worm gear 21, and a screw rod 22 screwed into the worm gear 21, as shown in FIG. It may be.

Artificial turf is made of synthetic resin and artificial turf leaves 1 made of synthetic resin are densely planted on the upper surface of 1.
is slightly tilted in a certain direction (for example, backward).

On the sidewalk of a golf course, the road shoulder is slightly curved as shown in FIG.
3. If there is a slightly uneven surface in the center of the sidewalk, bend it slightly outward to fit the road shoulder.
3 is automatically adjusted up and down around the left and right horizontal axis 10,
It adapts to sloped surfaces (uneven surfaces). By lowering the machine platform 7 using the upright cylinder 14, the press plate 3 is pressed against the artificial grass blade 1 below, and the weight of the platform 6 is applied to the grass blade 1 via the pressing tool 12. Therefore, presser plate 3
can already supply sand 2 and press down the artificial turf leaves 1. In this state, the driving device 9 is operated to alternately slide the adjacent reciprocating sliding plates 8.8 back and forth, thereby reciprocating the adjacent presser plates 3.3 alternately forward and backward. It is something. 24 in the figure is a wear-resistant cloth sheet stretched on the lower surface of the presser plate 3, 25 is a sand feeder, 26 is an artificial grass leaf scraper, 27 is a steering handle, and 10 in Figure 6 is a presser foot. This is a rotating bin with a plate 3 that moves up and down.

"Effect" Since the present invention is based on the method described above, the sand 2 supplied on the artificial grass leaves 1 that are densely planted on the sheet can be quickly and easily packed between the grass leaves, and evenly packed without requiring any skill. There are benefits to be gained.

Since the present invention employs the above-described apparatus, the sand 2 supplied onto the artificial grass leaves 1 densely planted on the sheet can be quickly and easily packed evenly between the artificial grass leaves 1 without wasting any labor. Furthermore, the traveling speed can be adjusted and maintained at a constant level, and the jamming caused by the presser plate 3 can be averaged out.
