Description

  The present invention relates to a ground leveling dragonfly for leveling soil and sand on the ground of a baseball field or an athletic field.

  Conventionally, ground leveling dragonflies have been used for leveling soil and sand on the grounds of baseball fields and athletic fields. For example, a conventional ground leveling dragonfly disclosed in Patent Document 1 has a leveling plate (dragonfly plate) fixed at a substantially right angle to a rod-shaped handle. In the dragonfly of this Patent Document 1, a comb-like portion for scoring the ground is provided on the side of the leveling plate, and a smoothing portion for smoothing the ground is provided on the side opposite to the side of the leveling plate. The base plate is made of wood and the comb-shaped part is made of metal. The wood constituting this leveling board is natural wood.

JP 2002-143360 A

  However, if the conventional leveling board (dragonfly board) that smoothes the ground smoothly is worn out in contact with the ground and is gradually scraped, which will destroy the ground leveling registration mark itself? The ground leveling plate (dragonfly plate) must be replaced and the worn leveling plate (dragonfly plate) must be discarded, and the discarded part cannot be regenerated, resulting in unilateral consumption of natural resources.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a ground leveling dragonfly that suppresses the depletion of natural resources such as natural wood and considers the natural environment.

  The ground leveling dragonfly according to claim 1 is characterized in that the rake plate that scratches the ground or the dragonfly plate that smoothes the ground is formed of an artificial tree.

  The ground leveling dragonfly according to claim 2, wherein the artificial tree is extruded by kneading paper mills discharged in the process of manufacturing paper at a paper mill and waste plastics discharged from a household or business office and pulverized It is characterized by being molded.

  The ground leveling dragonfly according to claim 3 is characterized in that the artificial tree can be reused as a rake plate and a dragonfly plate by reprocessing and remolding.

  According to the invention of the present application, an artificial tree is used as a rake board that scratches the ground or a dragonfly board that smoothes the ground, and the papermaking jar and households and business establishments that are discharged in the process of manufacturing the paper at the paper mill Because it is extruded and kneaded with waste plastic that has been discharged and pulverized, etc., and can be recycled and reused, it suppresses the depletion of natural resources such as natural wood and considers the natural environment can do.

It is a perspective view showing an example of a ground leveling dragonfly according to the present invention. It is a perspective view which shows the lower surface of the register mark for ground leveling. 1 is a perspective view showing an example of a rake-shaped ground leveling dragonfly according to the present invention. FIG. It is a perspective view which shows the lower surface of the rake-shaped ground leveling register mark.

  The ground leveling dragonfly in the present embodiment performs leveling of soil or sand on the ground of a baseball field or an athletic field. FIG. 1 is a perspective view showing an example of a ground leveling dragonfly according to the present invention. FIG. 2 is a perspective view showing a lower surface of the ground leveling dragonfly.

  Hereinafter, description will be made with reference to FIGS. 1 and 2. 1 and 2 includes a rod-shaped handle 12, a substantially rectangular plate-shaped register mark plate 20, and the like. The handle 12 has a column 16 or a cylinder, and a bracing plate 14 in which a bottom piece 14a is folded back in a triangular shape is fixed by bolts 16 from the lower end portion of the outer peripheral surface upward. The handle 12 and the bracing plate 14 are made of wood or metal (iron may be used but aluminum is preferable from the viewpoint of weight reduction).

  A registration mark plate 20 is attached to the lower side of the bottom piece 14 a of the bracing plate 14 with bolts 18 at a right angle to the handle 12. The registration mark plate 20 is a substantially rectangular plate material, and an upper portion at the center in the longitudinal direction is cut so as to be squeezed by the width of the bottom piece 14a of the bracing plate 14, and an attachment portion 24 is formed. And the attachment part 24 is being fixed to the bottom piece 14a of the bracing board 14 in the state which the registration mark board 20 extended sideways. The corner opposite to the handle 12 on the lower surface of the leveling portion 22 extending to the side of the registration mark plate 20 is chamfered, and the lower surface on the handle 12 side is the leveling surface 26.

  The material of the dragonfly board 20 is an artificial wood, which is made by kneading paper slag (paper sludge) discharged in the process of manufacturing paper at a paper mill and waste plastics pulverized and discharged from households and business establishments. It has been molded. Paper sludge is a short fiber basket that does not become recycled paper that is discharged when recycling used paper or paper packs in a paper mill. Waste plastic is recycled plastic that is recycled from plastic containers and plastic packing materials that are collected separately by the local government. As an artificial tree using paper sludge or waste plastic which is this waste material, for example, there is ECOPARMA / Eco Palma (registered trademark) manufactured by Suzuyo Corporation. When an artificial tree is actually used as the registration mark plate 20, it is processed into the shape of the registration mark plate 20 as described above by cutting and cutting.

  When this ground leveling dragonfly 1 is used, the leveling surface 26 of the registration mark plate 20 is rubbed against the ground to level the ground smoothly. The material and shape of the handle 12 and the bracing plate 14 are not limited. And while ground maintenance is repeated, naturally the leveling ground 26 of the registration mark plate 20 becomes worn and it becomes difficult to level the ground. In this case, the registration mark plate 20 may be replaced with a new one. Then, the registration mark plate 20 that has been worn out and removed is reused as the registration mark plate 20 by reprocessing and remolding (not only the registration mark plate 20 but also a rake plate 30 to be described later). Possible). For this reason, as the artificial tree of the registration mark board 20, a material that can be recycled and reused is preferable, and the above-mentioned ECOPARMA / Eco Palma is possible.

  The ground leveling dragonfly 1 to which the dragonfly plate 20 is attached smoothes the ground surface, but there is also a so-called “gully” that scratches the ground surface. The ground leveling register mark 2 shown in FIGS. 3 and 4 corresponds to the gully. FIG. 3 is a perspective view showing an example of a rake-shaped ground leveling dragonfly according to the present invention. FIG. 4 is a perspective view showing a lower surface of the rake-shaped ground leveling dragonfly.

  In the ground leveling dragonfly 2 shown in FIGS. 3 and 4, the handle 12 and the bracing plate 14 are the same. A rake plate 30 is attached to the lower side of the bottom piece 14 a of the bracing plate 14 with bolts 18 at right angles to the handle 12. The rake plate 30 is a substantially rectangular plate material, and a plurality of square pyramid rake portions 34 are cut side by side on the lower surface in a lying state. A horizontally long flat plate portion of the rake plate 30 is fixed to the bottom piece 14 a of the bracing plate 14. The material of the rake plate 30 is the same as that of the registration mark plate 20 described above.

  When using the ground leveling dragonfly 2, the ground is scraped so that the tip of the rake portion 34 of the rake plate 30 is rubbed against the ground. The material and shape of the handle 12 and the bracing plate 14 are not limited. As the ground maintenance is repeated, the rake portion 34 of the rake plate 30 is naturally worn or chipped, making it difficult to scratch the ground. In this case, the rake plate 30 is replaced with a new one. You just have to do it. The rake plate 30 removed due to wear or chipping is reused as the rake plate 30 by reprocessing and re-molding (not only the rake plate 30 but also the dragonfly plate 20 can be reused). ). For this reason, the artificial wood of the rake board 30 is preferably a recyclable and reusable material, and the above-mentioned ECOPARMA / Eco Palma is possible.

  According to the ground leveling dragonflies 1 and 2 having such a structure, an artificial tree is used for the rake plate 30 for scratching the ground or the dragonfly plate 20 for smoothing the ground, and the artificial tree manufactures paper in a paper mill. It is made by extruding and molding paper mills that are discharged from the factory and waste plastic that has been discharged and pulverized from homes and offices, and can be recycled and reused. It can control the depletion of resources and consider the natural environment.

  As described above, according to the present invention, it is possible to provide a ground leveling dragonfly that suppresses the depletion of natural resources, such as natural wood, and considers the natural environment.
