Description

[Detailed Description of the Invention] This invention relates to a forest disaster prevention sprayer for exterminating pests (for example, pine borers) parasitic on tall trees, among pest control machines used for spraying chemical solutions.

Generally, in order to exterminate pests that parasitize tall trees (such as pine borers that parasitize pine trees), chemical solutions are sprayed by helicopters. Spraying using a helicopter is effective in exterminating pests because the chemical solution can be spread almost uniformly over the entire tall tree. However, if the tall tree is adjacent to a private house, it may cause chemical damage to residents of the private house and livestock.

This idea was devised in view of the above-mentioned circumstances, and its purpose was to connect a chemical tank mounted on a mobile machine capable of driving, a spray pump connected to the chemical tank, and a spray pump connected to the spray pump. By equipping a boom with a nozzle attached to its tip and which can be raised and lowered as well as extended and retracted,
Chemical solutions can be applied almost uniformly to only the tall trees that are infested with pests, and even if there is a private house adjacent to the tall tree, the pests can be effectively removed without causing chemical damage to residents and livestock. An object of the present invention is to provide a forest disaster prevention sprayer that can exterminate.

Hereinafter, this invention will be explained in detail based on an embodiment shown in the accompanying drawings.

FIG. 1 is a side view showing the entire forest disaster prevention sprayer according to this invention. In the figure, 1 is a traveling machine that can run on wheels 2, and a cabin 3 is formed on the right side of the front part of the traveling machine 1. (shown in FIG. 2), a driver's seat 4 is disposed within the cabin 3. A chemical liquid tank 5 is arranged in the center of the traveling machine 1. The chemical tank 5 is connected to a main water supply hose 7 via a main water supply pump 6 (shown in FIG. 2), and this main water supply hose 7 is connected to a water source (not shown). The main water supply pump 6 and the chemical solution hose 7 are used to supply water from the water source into the chemical solution tank 5 when the water source is relatively close.

A boom 10 is attached to the rear of the traveling machine 1 via a bracket 9 which is rotatable about a vertical axis by a motor 8. The boom 10 can be raised and lowered about a support shaft 11' by a raising and lowering cylinder 11, and has a boom base 12 and a first inner boom that is telescopically installed inside the boom base 12, as shown in FIG. 13, second inner boom 14,

The bearing 81 has a circular reel portion 82 formed of a pipe.
is installed on the shaft. A handle 83 (shown in FIG. 14) is attached to the side of the reel part 82, and the reel part 82
2 can be manually rotated. Further, a handle 84 formed of a pipe bent upward into an L-shape is fixed to the upper part of the bearing 81. As described above, four hose reels 38 are mounted on the traveling machine 1, each having a 25 m auxiliary water supply hose 39 wound thereon. The auxiliary water supply pump 37 is carried close to the water source, and the auxiliary water supply pump 37 and the chemical solution tank 5 are connected by the auxiliary water supply hose 39. At this time, since the hose reel 38 is removable, it can be carried to any location, and the auxiliary water supply hose 39 can be connected more easily.

As described above, according to the forest disaster prevention sprayer of this invention, for example, when spraying a chemical solution on a pine tree in order to exterminate pine borers parasitic on the pine tree, the nozzle 19 attached to the tip of the boom 10 can be used. Since the chemical solution can be sprayed almost uniformly only on pines infested with pine borers, even if there is a private house adjacent to the pine forest, the pine borers can be sprayed without causing any harm to the residents or livestock. It is possible to exterminate. In addition, since the boom 10 can be raised and lowered and extended and contracted, when moving the sprayer,
It can be easily moved even on narrow forest roads. In addition, the nozzle 19 has a long distance nozzle tip 20.
Since the wide-angle nozzle tip 21 is attached, the nozzle tip to be used can be easily attached to the operation panel 32 even when working on slopes where the nozzle 19 cannot be approached even when the boom 10 is extended to its maximum extent, or when the extermination area is wide. It is possible to perform spraying operations easily by simply switching between the two positions. Further, during the above-mentioned chemical spraying operation, the nozzle 19 is rotatable around the longitudinal direction of the boom 10 and swingable in the same longitudinal direction, and furthermore, these operations can be easily performed using the operation panel 32. Therefore, it has the effect of being able to spray a chemical solution around the traveling machine 1 without having to move the traveling machine 1 each time, and its utility value is remarkable.
