2. Description of the Related Art A horizontally elongated boom is attached to a traveling vehicle body so that both ends of the boom are largely protruded to the outside, and a spraying agent is widely spread from a plurality of nozzles provided on the boom.

[0003]

The utility poles and other obstacles on the side of the traveling vehicle body moving forward may hit the boom projecting laterally and hinder the spraying work. Boom
Since the projecting portion is configured to be folded for storage and the like, the boom on the obstacle side is folded and used in the above case. Then, the agent to be sprayed cannot be spread over a wide range. According to the present invention, the boom is provided so as to be able to move to the left and right, and by avoiding obstacles by its lateral movement, the area in which the sprayed material cannot be sprayed is reduced, and the boom overlaps on the protruding side due to lateral movement. It tries to prevent the spraying.

According to the present invention, in order to solve the above-mentioned problems, a horizontally long boom 10 having a plurality of nozzles 18 arranged side by side is arranged on a traveling vehicle body 1 so that both ends of the boom 10 largely project outward. And the boom 10 is the vehicle body 1
The nozzle 18 is provided so as to move to the left and right with respect to the horizontal direction of the boom 10, and when the nozzle 18 moves outside the position of the nozzle 18 at the outer end in the standard state, the supply of the sprayed agent in the tank 19 stops The sprayer is provided so that

[0005]

Since the present invention is constructed as described above, the plurality of nozzles 18 attached to the boom 10 widely spread the chemicals and other sprayed materials as the traveling vehicle body 1 advances. Then, when the traveling vehicle body 1 is moving forward, if there is an electric pole or other obstacle beside it and there is a possibility that it may hit the protruding boom 10, the boom 10 is moved laterally immediately before that to avoid the obstacle. , When the boom 10 has passed the side of the obstacle, move it in the opposite direction to restore it. At this time, on the opposite side of the obstacle, the boom 10 projects outward, but the nozzles 18 of this projecting portion automatically stop the spraying of the sprayed agent.

[0006]

As described above, according to the present invention, when an obstacle such as a utility pole is present during the spraying of a chemical or other spraying agent, in order to avoid the obstacle, the boom 10 provided with the nozzle 18 is provided.
Is moved to the left and right with respect to the traveling vehicle body, the area where chemicals and the like are not sprayed is small, and since the chemicals and the like are not automatically sprayed from the nozzles 18 projecting to the opposite side by the lateral movement, the front stroke or the rear stroke This has the effect that the sprayed material in the process and the sprayed material do not overlap.
