2. Description of the Related Art Conventionally, soil has been covered on the same day to cover the surface of garbage for the purpose of preventing offensive odor and scattering of garbage at a landfill site. However, there is a problem that the soil filling operation reduces the valuable landfill volume and the soil covering work is not easy. Therefore, in recent years, chemical spraying has come to be performed as a method of replacing the function of soil covering on the same day at the landfill site of garbage.
In this case, the garbage piles removed from the garbage truck at the landfill site are leveled by a compacting machine and then sprayed with chemicals. For this chemical spraying, a spraying nozzle is fixed to the rear of the traveling direction of the self-propelled vehicle, and the spraying is performed while the self-propelled vehicle is traveling.

[0003]

As described above, the dust piles removed from the garbage collection vehicle are smoothed by a compacting machine or the like, but the traveling surface on which the self-propelled vehicle travels is
It is still uneven, and the position of the spray nozzle attached to the rear of the self-propelled vehicle moves up and down as the self-propelled vehicle travels,
There has been a problem that the distance between the nozzle and the dust surface of the dust surface fluctuates drastically, and it is not possible to spray the dust uniformly.

In addition, a place where the vehicle cannot run, for example,
There is a problem that the edges, corners and slopes of the landfill site cannot be sprayed.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to eliminate the uneven spraying due to the deviation of the nozzle position caused by the traveling of the self-propelled vehicle and to uniformly disperse the medicine, and at the same time, the self-propelled vehicle It is an object of the present invention to provide a self-propelled spraying device that can spray a drug even in a place where traveling is impossible.

The header 16 and the flexible tube 27 (see FIGS. 1 to 3).
(Not shown) are connected to each other.

In the medicine supply section 20, the foaming agent is supplied from the foaming agent tank 21 to the foaming device 26 by the pump 23, and mixed with the air supplied from the compressor 25 to foam. The chemical liquid sufficiently foamed by the foaming device 26 is supplied to the spray nozzle 14 via the header 16. On the other hand, the solidifying agent is supplied from the solidifying agent tank 22 to the pump 2

Here, in this embodiment, the foaming agent is composed of phosphoric acid, a hydrocarbon-based anionic surfactant and the like as components, and the solidifying agent is an aqueous solution of a polycondensate containing amino-based resin as a component. Further, a spiral body 45 is fitted in the auxiliary nozzle 43 if necessary. Therefore, the spraying nozzle 14 can perform the mixing and spraying of the two liquids almost simultaneously by supplying the foaming agent and the solidifying agent separately.

Next, the operation of the self-propelled spraying device configured as described above will be described with reference to FIGS. 6 to 8. First, at the landfill site, the surface of the garbage pile removed from the garbage collection car is leveled by a compacting machine. After that, the self-propelled spraying device according to the present invention is operated. FIG. 6 is an example showing a case in which a chemical is sprayed on a refuse landfill site which is uneven but has a substantially flat shape. First, the self-propelled vehicle 1 is run and stopped at a predetermined position. Next, as shown in FIG. 6 (a), while spraying the drug supplied from the drug supply unit 20 from the spray nozzle 14, the support shaft 4 is rotated in the forward and reverse directions as indicated by the arrow A, thereby spraying the drug. The nozzle 14 can be rotated about the support shaft 4 with a predetermined radius. As a result, as shown in FIG. 6B, it is possible to spray the drug on the area A ₁ in a substantially fan shape on the plane. Next, by operating the hydraulic cylinder 8 to move the tip of the arm 6 back and forth as indicated by arrow C, and by operating the rotary actuator 5 to rotate the support shaft 4 as indicated by arrow A. The chemicals are sprayed on a region A ₂ indicated by diagonal lines between the outer edge of the landfill site shown in FIG. 6B and the fan-shaped region A ₁ . Next, after the self-propelled vehicle 1 is driven, the same work is performed again, and as shown in FIG.
_3, spraying an agent to A _4.

FIG. 7 is a view showing another example in which the medicine is sprayed on the flat surface of the landfill disposal site which is made substantially flat. In this example, as shown in FIG. 7A, the support shaft 4 is rotated, the arm 6 is moved back and forth, and the headers 13 and 1 are moved.
The medicine is sprayed while rotating 6. That is, while spraying the drug supplied from the drug supply unit 20 from the spray nozzle 14 and rotating the support shaft 4 in the forward and reverse directions as shown by the arrow A, the hydraulic cylinder 8 is operated to operate as shown by the arrow C. Then, the tip of the arm 6 is moved back and forth in the axial direction of the arm 6 to spray the medicine from the spray nozzle 14. At this time, the rotary actuator 15 is operated to operate the headers 13, 1
6 is rotated slightly around the axis of the link 10 as shown by the arrow E, so that the spray nozzle 14 is moved to the position shown in FIG.
It is possible to proceed in a direction perpendicular to the paper surface in the state shown in (4), and the medicine is sprayed in a rectangular shape in the area A _{5 as} shown in FIG. 7 (b). That is, the edge portion and the corner portion can be surely sprayed. Then the area A _6, as shown in FIG. 7 (c) by performing again the same operation after running the moving vehicle 1
The drug can be sprayed on. Note that the headers 13 and 1
6 may be composed of one pipe with a partition provided in the center, or may be composed of two separate pipes.

FIG. 8 shows an example in which the slopes having the inclination angle θ are scattered. In this example, as shown in FIG. 8 (a), three operations are performed, namely, the forward / backward movement of the arm 6 indicated by the arrow C, the swing of the arm 6 indicated by the arrow B, and the swing of the link 10 indicated by the arrow D. . That is, while spraying the drug supplied from the drug supply unit 20 from the spray nozzle 14, the hydraulic cylinder 7 is operated and the arm 6 is swung in the vertical direction as indicated by the arrow B to operate the hydraulic cylinder 8. The arm 6 is moved back and forth as indicated by arrow C, and the hydraulic cylinder 11 is operated to swing the link 10 as indicated by arrow D. As a result, the spray nozzle 14 can spray the medicine from the top to the bottom or from the bottom to the top along the slope S while being substantially orthogonal to the slope S and always keeping a constant distance from the slope S.
As a result, the drug is sprayed in a rectangular shape in the area A _{7 as} shown in FIG. Next, by moving the self-propelled vehicle 1 and then performing the same operation again, the medicine can be similarly sprayed to the area A ₈ as shown in FIG. 8C. At this time, the rotary actuator 15 is operated to move the arrow E.
As shown in FIG. 8A, the headers 13 and 16 can be rotated with respect to the axis of the link 10. In the description of the embodiment shown in FIGS. 6 to 8, an example in which the self-propelled vehicle 1 is sprayed in a stopped state has been described, but the self-propelled spraying apparatus of the present invention causes the self-propelled vehicle 1 to travel. Needless to say, it can be sprayed in the state where it is laid.

[0022]

As described above, according to the present invention,
It is possible to eliminate the uneven spraying caused by the displacement of the nozzle position caused by the traveling of the self-propelled vehicle, and it is possible to uniformly spray the medicine. In addition, it is possible to easily spray the chemicals on a place where the self-propelled vehicle cannot run, such as an edge portion, a corner portion, and an inclined surface of the waste landfill site.
