Abstract

PROBLEM TO BE SOLVED: To efficiently improve soil under a lawn surface and to raise the lawn by forming narrow holes for dethatching and aeration on the surface of the lawn lifting and lowering a lifting and lowering part while simultaneously traveling. SOLUTION: Soil under a lawn surface 7 is improved by forming marrow holes 8 and 9 on the lawn surface 7 by lifting and lowering a lifting and lowering part 1 whose holder 2 has a much tine 3 for dethatching installed in the front of the holder 2 and a side-open tine 4 for aeration installed in the rear of the holder 2 in the driving direction A to hang down, while simultaneously traveling. Moreover, the much tine 3 is preferably installed so as to hang down longer than the side-open tine 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for improving the soil on the lawn surface of a golf course, a park or the like to grow grass.

[0002]

2. Description of the Related Art As one method for improving the soil on the lawn surface, there is a method in which a fine hole is formed in the lawn surface to allow rainwater or air to penetrate into the soil or to be used as a fertilizing hole. is there.

There are also two kinds of forming means in this small hole, one is simply formed by piercing a round bar,
Others have a cylindrical shape and have a blade at the tip (lower end) and pierce the cylindrical body having a long hole on the side surface to dig up the soil in the cylindrical body to form it.

The former fine holes are mainly for the purpose of permeating water into the soil, and the latter fine holes are for the main purpose of permeating air into the soil. The rods are called muck tines for desaching, and the cylinders are called side open tines for aeration, and they are attached to the holder of the elevating part of the soil improvement machine for exclusive use, and the work of forming the fine holes is performed.

As described above, a dedicated machine is used for soil improvement on a vast lawn surface, and the dedicated machine has an elevating part that reciprocates in the vertical direction at the rear part of a self-propelled machine body,
The tines are attached to the holder of the elevating part, and the fine holes are continuously formed by the tines attached to the elevating part while traveling.

Further, since the two kinds of small holes are formed individually, that is, only one of the shunting tine for desaching or the side open tine for aeration is attached to the holder of the elevating part to perform desaching or The small holes for aeration are formed.

This is because the purpose of forming each fine hole and the tines used are different, so it was considered as a separate work, and naturally, the same place is moved twice to form each fine hole. .

[0008]

In view of the above problems, the present invention is to provide a more efficient method for improving the soil on the lawn surface, by which small holes for desaching and aeration can be formed at one time. .

[0009]

According to the method of the present invention, a shunting tine for desaching and a side open tine for aeration are provided in front of a holder of an ascending / descending portion and a side opening tine for aeration so as to hang down with respect to a moving direction. Is characterized by raising and lowering to form a small hole on the grass surface, and the muktain may be hung longer than the side open tine.

According to the present invention, since both the muck tine and the side open tine are attached to the holder of the elevating part, two kinds of fine holes can be formed on the grass surface by one step at a time by elevating. Since the front side and the side open tine are the front side and the rear side open tine with respect to the moving direction, the front side tractor tine acts to dig up the soil, thereby promoting the aeration action by the rear side open tine.

Further, since the positional relationship between the muck tine and the side open tine is fixed, two kinds of fine holes can be regularly formed and work can be performed without excess or deficiency. Further, by making the muck tine hang longer than the side open tine, the excavation action is increased and the aeration action by the side open tine is further promoted.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the method of the present invention will be described with reference to the drawings. In the holder 2 of the elevating part 1 provided at the rear part of the self-propelled machine body, in the traveling direction A of the machine body, a shunting muck-in 3 is hung vertically on the front part and a side for aeration on the rear part. The open tines 4 are installed vertically. A plurality of mute tines 3 and side open tines 4 are arranged side by side in the lateral direction.

The side open tine 4 is a cylindrical body having a blade 5 formed at the hanging lower end, has a long hole 6 for removing soil on the side surface, and excavates the soil in the piercing cylinder into the ground. Further, the muck tine 3 hangs longer than the side open tine 4, and the descent of the elevating part 1 causes the muck tine 3 to move.
Stabbed grass surface 7, then side open tine 4
Will be stabbed.

Therefore, as the machine body moves by itself, the elevating part 1 moves up and down to form the fine holes 8 and 9 for each purpose.

[0015]

As described above, according to the method of the present invention, both the work is performed at the same time while the conventional method performs the desaching and the aeration separately. By adjusting the number of side open tines installed, the ratio of each small hole can be easily selected.
It has the effect of obtaining work suitable for lawn surfaces.

Further, the excavation action of forming a small hole by press-fitting the desquating mucktaine affects the surrounding lawn surface and the soil, and promotes the action of aeration to excavate the soil by cutting the rear side open tines. However, the aeration effect is enhanced, and if the mucktaine hangs longer than the side open tines, the mucktaine will more quickly rush into the soil, further increasing the effect.
