[0002]

2. Description of the Related Art Conventionally, a net-like rug having a width of about 30 cm × 30 cm or 30 cm × 15 cm and a thickness of several millimeters has been used for growing and transplanting lawn in a field. That is, a large number of such rugs are laid side by side next to each other on a field, soil is put on the rug, and a lawn seed is sown. Then, after the lawn buds emerged to grow the lawn, the rug was peeled off together with the lawn, conveyed in a stacked state, and transplanted to another place.

[0003]

As described above, it is troublesome to grow, collect, and transplant a lawn using a large number of rugs because the number of rugs is large, and therefore the present application is intended to solve the problem. People are thinking of using long, large-area rugs in the form of strips. However, in such a state in which the rug and the lawn having a large area are rolled up, the weight becomes very heavy, which may make the handling work difficult.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a natural lawn loading and unloading apparatus capable of easily handling a heavy load of a long rug wrapped with a lawn along with a lawn. And

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention is applied to a field and soil is put on the field.
In addition, a pair of engaging portions that engage with both ends of a winding shaft for winding a rug on which lawn seeds are sown and that grows lawn, a frame in which these engaging portions are formed, and a rope for lifting the frame are provided. And a mounting portion for mounting.

[0006]

The engaging portions of the device of the present invention are engaged with both ends of the winding shaft for winding the belt-like rug together with the lawn. The frame having this engaging portion is hung up by the rope attached by the attaching portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the rug used in this example has a strip shape having a width W of 1.2 to 1.8 meters and a length L of about 20 meters. The rug 1 itself is made of nylon and is extremely flexible. By using such a flexible thing, the lawn and the rug 1 can be wound and stored or transported due to the flexibility and the vitality of the lawn itself. The mesh-like mesh of the rug 1 may have various sizes, but if it is too large, the grass roots are less likely to be entangled, and the grass may fall off when the rug 1 is wound. Conversely, if the mesh is too small, it lacks flexibility and becomes difficult to wind. Therefore, it is desirable to adopt a mesh range having a size that satisfies the above two conditions.

A downward pin 3 is fixed to the lower surface of the rug 1 as a shift preventing means. The pins 3 are provided, for example, at intervals of 2 meters in the length direction of the rug 1, and the rug 1 is placed on the field.
Prevents the grass from being cut off when it is laid.

Around the rug 1, a magic fastener 5 (registered trademark) is provided as a joint means for joining with another rug 1. The magic fasteners 5 are provided, for example, at intervals of 2 meters in the longitudinal direction of the rug 1. The rugs 1 are provided so as to face upward around the one rug 1 and downwardly around the other rug 1, and the rugs 1 are joined to each other by the magic fasteners 5 overlapping and adhering to each other.

A method of growing lawn using the rug 1 as described above will be described with reference to FIG. First, the rug 3 is laid on the soil 7 in the field. At this time, the pin 3 is pierced into the soil 7 so that the rug 1 is not displaced with respect to the soil 7 (FIG. 3A).
Further, the rugs 1 adjacent to each other are jointed with a magic fastener 5. In this way, a large area of the field is covered with the rug 1. Then, put the soil 9 on the rug 1 (Fig. 3
(B)). The soil 9 also enters the net-like mesh of the rug 1 so that the grown lawn is easily entangled with the mesh-like mesh. Next, the lawn seed 11 is sown (FIG. 3 (c)). Then, water and fertilizer are added, and the grass 13 grows after a predetermined time has passed (FIG. 3 (d)).
