DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, a method for renovating a weedy ground 10 according to the present invention will be described with reference to the drawings.

[0014] Figure 1 is a photograph of the ground 10 before renovation. Before renovation, the ground 10 was overgrown with weeds 100. If the weeds 100 were removed in this state, many unevenness would remain on the surface of the ground 10, causing drainage problems such as a worsening of the water gradient and the formation of puddles and mud after rainfall.

[0015] As described above, the renovation method for the ground 10 overgrown with weeds 100 can be composed of a cutting step, a shredding step, a root cutting and mixing step, a first leveling step, a second leveling step, a compaction step, a finishing step, and a spraying step. Each step will be described in detail below.

[0016] <Harvesting step> In the mowing step, weeds 100 that have grown on the ground 10 are mowed and collected by a mower 20. The mower 20 may be a riding type as shown in FIG. 2, or it may be a brush cutter. It is desirable to mow the weeds 100 so that the height is about 1 cm to 10 cm. The mowed weeds 100 can be collected and carried outside the ground 10. This roughly completes the upper layer of the above-ground portion of the ground 10.

[0017] <Shredding step> After the weeds 100 have been cut, roots remain in the soil on the ground 10, and leaves and stems of the weeds 100 remain on the surface of the ground 10. These remaining roots, leaves, and stems are then chopped into mince pieces by a spiral cutter 30 to remove the weeds. The spiral cutter 30 can be attached to the rear of a tractor 25, as shown in Figure 3(a).

[0018] As shown in Fig. 3(b), the spiral cutter 30 has blades 31 arranged in a spiral shape. The blades 31 are attached to a ring-shaped frame 32. The spiral cutter 30 is provided with a rotating shaft 33, which is driven by power received from the drive shaft of the tractor 25 to rotate the spiral cutter 30.

[0019] The spiral cutter 30 is preferably configured so that the blade 31 penetrates the surface soil of the ground 10 by, for example, about 1 cm to 3 cm, and the leaves, stems, and roots remaining on the ground 10 are chopped into mince pieces and mixed into the surface soil.

[0020] <Root cutting and stirring step> Next, as shown in FIG. 4(a), the ground 10 is tilled by a tractor 25 equipped with a tailor attachment 40. The tailor attachment 40 may have a plurality of tiller tines 41 attached to a rotating shaft 42, as shown in FIG. 4(b). The illustrated tiller tines 41 are so-called hatchet tines. The rotating shaft 42 is driven by power received from the drive shaft of the tractor 25, causing the tailor attachment 40 to rotate.

[0021] The tailor attachment 40 is preferably capable of penetrating deeper into the surface soil than the spiral cutter 30. The depth of penetration of the tiller tines 41 into the surface soil is, for example, approximately 3 cm to 10 cm, preferably approximately 3 cm to 5 cm. This allows the leaves, roots, and stems that were chopped into mincemeat in the chopping step to be further chopped, and also cuts into the roots remaining underground, completing the weeding process. The chopped and root-cut weeds are then further stirred and mixed with the surface soil by the tiller tines 41. The tailor attachment 40 can also soften the surface soil.

[0022] <Unevenness correction> The root cutting and mixing step causes the surface of the ground 10 to become uneven. Therefore, unevenness leveling is performed to correct the unevenness and elevation differences on the surface of the ground 10. In this embodiment, the unevenness leveling step is configured to include a first unevenness leveling step and a second unevenness leveling step. However, the unevenness leveling step may be either one of them, or may be performed by another method.

[0023] <First step of leveling unevenness> The first unevenness leveling step is a step in which the ground mat 50 is towed by the tractor 25 to level the unevenness, as shown in FIG. 5(a). The ground mat 50 can be made of a flexible mesh member 51 made by weaving resin, string, metal wire, etc., as shown in FIG. 5(b). One end of the mesh member 51 is attached to a support rod 52. The support rod 52 is provided with a U-shaped angle 53, and a wire 54 is hung on the angle 53, and the mesh member 51 is attached to the tractor 25 so that it makes good contact with the ground 10.

[0024] Then, by towing the ground mat 50 with a tractor 25 as shown in Figure 5(a), the mesh member 51 roughly corrects unevenness and elevation differences in the surface soil, leveling the unevenness. Because the mesh member 51 is flexible, it can smoothly move along the surface of the ground 10, allowing for effective correction of unevenness.

[0025] The stems, leaves and roots of weeds get caught on the mesh member 51 and float to the soil surface, so the floating weeds can be collected and disposed of as needed.

[0026] <Second unevenness correction step> The second unevenness leveling step can be performed by towing a planer cutter 60, which is made of steel materials 62 assembled into a rectangular frame, with a tractor 25, as shown in FIG. 6(a). As shown in FIG. 6(b), the planer cutter 60 has U-shaped angles 67 attached to the left and right sides of one side of a rectangular frame 61, and a wire 68 hung on the angle 67, so that it can be towed by the tractor 25. It is also possible to hang the wire on the corner of the rectangle. To prevent the planer cutter 60 from floating up, it is desirable to place a weight 69 on the rear side.

[0027] FIG. 6(c) is a cross-sectional view of the planer cutter 60. The planer cutter 60 can be configured, for example, by arranging equal-legged (L-shaped) steel members 62 in an inverted L shape, assembling them into a rectangular frame with the vertical members on the outer periphery, and bolting 64 a flat blade member 63 to the outer periphery of the vertical portions of the steel members 62. Using high-tensile steel for the blade member 63 reduces wear. Furthermore, bolting 64 for the blade member 63 makes it easy to replace the blade member 63 when it wears. It is preferable to reinforce the bent portion of the L-shaped steel member 62 with build-up welding 65 to prevent it from opening. It is also preferable to attach a reinforcing plate 66 or the like to the corners where the steel members 62 intersect.

[0028] By towing the planer cutter 60 configured as described above with the tractor 25, the unevenness and elevation differences on the surface of the ground 10 that have been roughly leveled by the first leveling are further corrected. In the case of the planer cutter 60 of Figure 6(c), the front blade member 63 of the rectangular frame type scrapes away the soil in the higher parts, and the rear blade member 63 presses and levels it, thereby performing the leveling of unevenness in an appropriate manner.

[0029] Furthermore, the stems, leaves and roots of the weeds are caught by the blade member 63 and float to the soil surface, so the floating weeds can be collected and disposed of as needed.

[0030] <Compaction step> After the unevenness leveling step, the ground 10 is subjected to rolling compaction as shown in Figure 7(a). The rolling compaction can be performed by a roller compactor 70. The roller compactor 70 can be equipped with a wide tire roller 71 that has a wide, flat circumferential surface. In this case, as shown in Figure 7(b), it is desirable to use a wide tire roller 71 with a right-angled corner on the contact surface. This prevents the soil from piling up during rolling.

[0031] By performing compaction, the leveled ground 10 becomes almost flat.

[0032] <Finishing step> After the compaction step, a finishing step is preferably performed. In the finishing step, the ground 10 is finished using a tractor 25 equipped with a finishing tool 80, as shown in FIG. 8(a). As shown in FIG. 8(b), the finishing tool 80 can include a wire rake 81 having a number of downwardly facing wires 82 arranged in the width direction, a flat rake 83 having a number of wavy tooth members 85 formed on the underside of a flat plate 84 extending in the width direction, and a brush 86 having resin bristles 87 planted below a base 88 extending in the width direction. Note that the rake is not limited to a combination of the wire rake 81 and the flat rake 83. Furthermore, the finishing tool 80 can be configured to include all of the wire rake 81, the flat rake 83, and the brush 86 to more effectively finish the ground 10, but it is sufficient to include at least one of them.

[0033] The finishing jig 80 has a wire rake 81 at the front, a flat rake 83 behind it, and a brush 86 at the rear, and is pulled by the tractor 25 so that the wire 82, tooth member 85, and bristles 87 come into contact with the ground 10. In this way, the compacted ground 10 is lightly loosened by the wire 82, and the final height adjustment is made by the tooth member 85, and fine irregularities are smoothed out by the bristles 87 of the brush 86, resulting in a flat finish.

[0034] <Spraying step> Finally, a chemical agent is sprayed on the surface of the ground 10 as shown in Figure 9. Examples of the chemical agent include a soil stabilizer 90 and a herbicide 91.

[0035] Examples of soil stabilizer 90 include granules whose main ingredients are magnesium chloride, magnesium oxide, or calcium chloride, or a liquid obtained by dissolving these in water. Spraying soil stabilizer 90 can promote soil aggregation on ground 10, suppress dust generation and freezing, and improve drainage. Soil stabilizer 90 is not limited to the above ingredients. If soil stabilizer 90 is a granule, for example, as shown in Figure 9, a spreader 92 can be attached to tractor 25, and soil stabilizer 90 can be loaded into spreader 92 and sprayed onto ground 10. If it is a liquid, it can be sprayed using a hose 93, similar to herbicide 91 described below.

[0036] Furthermore, the herbicide 91 can be, for example, a chemical with a high salt concentration. The herbicide 91 can also be sprayed in the form of granules or liquid. The herbicide 91 is not limited to the above-mentioned components. Spraying the herbicide 91 can suppress the emergence of new weeds. If the herbicide 91 is a liquid, it can be sprayed using a hose 93, for example, as shown in Figure 9. If the herbicide 91 is a granule, it can be sprayed using a spreader 92, as with the soil stabilizer 90 described above.

[0037] By spraying the chemicals, the renovation work on Ground 10, which was overgrown with weeds, will be completed.

[0038] As described above, according to the ground 10 renovation method of the present invention, by using a series of steps consisting of a cutting step, a shredding step, a root cutting and mixing step, a first unevenness leveling step, a second unevenness leveling step, a compaction step, a finishing step, and a spraying step, weeds 100 are removed from the surface and soil of the ground 10, the ground is leveled, dust generation and freezing are suppressed for a long period of time, drainage is improved, and the ground 10 is in good condition where weeds 100 are less likely to grow.

[0039] The above description of the embodiment is for the purpose of explaining the present invention, and should not be construed as limiting the invention described in the claims or narrowing its scope. Furthermore, the components of the present invention are not limited to the above embodiment, and various modifications are possible within the technical scope described in the claims.

[0040] It should be understood that the devices used in each step are merely examples. The dimensions and shapes are also merely examples and do not limit the present invention. Although a baseball field is shown as the ground 10, it may be a soccer field, tennis court, softball field, or the like.

[0041] If there is not enough soil on Ground 10, more soil can be brought in as needed. [Explanation of symbols]
