BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for collecting latent topsoil used for slope planting.
[0002]
[Prior art]
As one of the slope revegetation methods to create a revegetation base on the slope, organic base materials such as park compost and growth base materials such as black soil are prepared and sprayed onto the slope with an air-mixing sprayer. Aside from this, the revegetation method using latent surface soil (deposition layer, surface layer, and earth and sand contained therein) before cutting has been known for a long time.
[0003]
The revegetation method, which uses this potential topsoil as a vegetation base, is expected to recover the local ecosystem because the buried seeds and soil microorganisms contained in the topsoil are effectively used. It is effective as a material to restore the local environment. In addition, the effective use of local soil is desired to be actively adopted as a trend.
[0004]
In order to collect this potential topsoil, conventionally, for example, the topsoil on the slope was scraped up so as to wipe between existing trees by human power.
[0005]
[Problems to be solved by the invention]
Such a manual collection work is not only a slope work but also an existing tree, so it is not easy and requires a lot of work and is not good. For this reason, there is almost no greening method using latent topsoil. On the other hand, it is possible to scrape by a machine such as a backhoe, but existing trees become obstacles and there is a limit to the slope of the slope where the machine can be used, so mechanization can only be performed within a limited range.
[0006]
The object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, easily collect potential topsoil even on an inclined surface where existing trees exist, improve workability of topsoil collection, and use latent topsoil as a vegetation base material The purpose of the present invention is to provide a topsoil collecting device that can easily realize the revegetation method to be used, can effectively use locally generated sediment and resources, and can respond to recent demands.
[0007]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view showing a first embodiment of a topsoil collecting device of the present invention, FIG. 2 is a front view of the same, FIG. 3 is a side view of the same, and a topsoil collecting device of the present invention is provided with a topsoil container 2. A material hose 3 is connected to the provided blower type suction machine 1, a suction nozzle 4 is provided at the tip of the material hose 3, and a topsoil loosening means is attached to the suction nozzle 4.
[0012]
This topsoil loosening means is constituted by an air injection device in the first embodiment, and this suction nozzle 4 comprises a plurality of, in the illustrated example, a hollow ring-shaped body 6 provided with eight air injection ports 5 at appropriate intervals. The air supply hose 8 was connected to the hollow ring-shaped body 6. The air injection port 5 is set at an angle such that air is injected toward the center of the suction nozzle 4.
[0013]
Then, a trumpet-shaped cover 7 is attached from the outer peripheral edge of the ring-shaped body 6 toward the front.
[0014]
Next, a method for collecting the latent surface soil (sediment layer, surface layer, and earth and sand contained therein) using the surface soil collecting apparatus will be described. FIG. 11 shows the first example. The topsoil collecting device is brought into the site, the suction machine 1 is installed at an appropriate place, the material hose 3 is extended, and the suction nozzle 4 at the tip is set to the potential of the slope 9. Apply to topsoil 12. Then, the air injection device is operated to inject air from the air injection port 5 through the air supply hose 8 and spray it onto the latent topsoil 12 of the slope 9.
[0015]
Thereby, since the soil and the porous material which are tightened are also loosened, they are easily sucked from the suction nozzle 4. In this way, the material is sucked from the slope 9 while loosening the material, and the sucked material is conveyed through the material hose 3 and collected in the accommodating portion 2. In this case, the air injection port 5 is directed toward the center of the suction nozzle 4, and a cover 7 is attached to the tip of the suction nozzle 4, so that the topsoil loosened by the injected air scatters around. There is nothing, and the suction nozzle 4 is surely collected.
[0016]
Such a collection operation only needs to move the suction nozzle 4 and the material hose 3 along the slope, so that the existing tree 10 growing on the slope 9 can be swept between them. It is also not limited by the slope of the slope.
[0017]
4 to 6 show the second embodiment, and the basic configuration is the same as that of the first embodiment, but a jet water injection device is provided as a topsoil loosening means. The structure of the jet water jetting device is the same as that of the air jetting device, and a plurality of, in the illustrated example, a hollow ring-shaped body 14 provided with eight jet water jetting ports 13 at appropriate intervals is suctioned. A jet water supply hose 15 was connected to the periphery of the tip of the nozzle 4 and connected to the hollow ring-shaped body 14. The jet water injection port 13 is set at an angle such that jet water is injected toward the center of the suction nozzle 4.
[0018]
Then, a trumpet-shaped cover 7 is attached from the outer peripheral edge of the ring-shaped body 14 toward the front.
[0019]
The method of collecting the sloped surface topsoil using such a topsoil collecting device is the same as that of the first embodiment, but as a method of loosening the potential topsoil 12, the latent topsoil is jetted from the jet water jet 13. 12 is loosened, and the topsoil in the form of slurry is sucked by the suction nozzle 4 and conveyed to the container 2 by the material hose 3.
[0020]
7 to 10 show a third embodiment, and the basic configuration is the same as that of the first and second embodiments, but the air injection device of the first embodiment and the jet of the second embodiment are used as topsoil loosening means. In addition to the water jetting device, a crushing device provided with a plurality of crushing blades 16 around the ring-shaped body 6 (14) was provided.
[0021]
As the first example, the crushing blades 16 are arranged as shown in FIG. 8 in which a plurality of crushing blades 16 are arranged on the surface of the rotating disk 18 at appropriate intervals, and in the illustrated example, five crushing blades 16 are arranged. As shown in FIG. 10, a rotary 19 can be used.
[0022]
In the third embodiment, since the latent topsoil 12 can be scraped and crushed like a warp with the pulverizing blade 16, the shape of the hard latent topsoil 12, branches, roots, and the like can be easily sucked. It can be easily sucked from the suction nozzle 4 and is easily transported to the accommodating portion 2 by the material hose 3.
[0023]
The method of using the topsoil collecting device is not limited to the example shown in FIG. 11 described above. As a second example, the wheel 20 is attached to the lower part of the suction machine 1 as shown in FIG. In this case, the suction machine 1 can be moved freely following the movement of the suction nozzle 4, so that the collection range can be expanded.
[0024]
Further, as shown in the third example of FIG. 13, by connecting the storage portions 2 of the plurality of suction machines 1 with the material hose 3, not only the collection range is expanded, but also the storage volume of the collected latent topsoil 12 is expanded. Therefore, a large amount of potential topsoil 12 can be collected in a single collection operation.
[0025]
Further, as shown in the fourth example of FIG. 14, if the suction machine 1 is lifted by the crane 21, the suction nozzle 4 can be used even at a high place or a steep slope where it is difficult to carry in and install the suction machine 1. The potential topsoil 12 can be collected by
[0026]
The latent topsoil 12 mechanically collected in this manner is used as a vegetation base material by a greening method using an air pressure or pump pressure method or a belt conveyor method. This makes it possible to effectively use resources such as buried seeds and soil microorganisms.
[0027]
Next, a description will be given of test results of suction ability of the branch and leaf chips, earth and sand, and slurry material obtained by mixing water with these when the suction machine 1 is used. The material hose 3 had a diameter of 100 mm and a suction distance of 10.30.50 m. Moreover, the suction material was two types of branch and leaf chips (large and small) having different sizes and loam masa, and these simple substance, branch and leaf chips, loam masa and water were mixed with a stirrer. The mixing ratio of branch and leaf chips (large and small) and loam masa was 50% each by volume ratio, and the mixing amount of water was 35%.
[0028]
The measurement method of the suction capacity is the suction time of the material. As a result of the measurement, it was found that smooth suction conveyance is possible, and that the suction capacity is improved by increasing the amount of air. It was also found that the collected material can be used as a vegetation substrate.
[0029]
【The invention's effect】
