まれてきた。However, there is no problem in the case of shrub and fruit trees such as mandarin oranges in the case of stopping the conventional spraying from the central spraying section and spraying only from the left and right sides. Trees with high height such as persimmons and persimmons can be sprayed evenly on the branches and leaves in the lower part when the leaves are overgrown, but the chemical solution may not be able to reach the branches and leaves above the trees. there were. In addition, in the conventional rocking type sprayer, the spray from each nozzle is rotated in an elliptical shape, and by spraying on the leaves that are swaying by the spray, spraying on the back surface of the leaves is possible. However, in the upper part of the tree, the momentum of the spray was weakened, and the repainting on the surface of the leaves was insufficient. As a result, uneven spraying occurred on the branches and leaves above the trees. Therefore, in order to spray the upper branches and leaves of the tree overgrown with leaves, the chemical solution is sprayed upward and downward from a high position near the upper part of the tree,
There has been a demand for a control machine that eliminates the uneven spraying on the branches and leaves above the trees.

A seal groove 42c is formed in an annular shape on the contact surface of 2b, a seal member 46 is fitted into the seal groove 42c, and a seal groove 44a is similarly formed on the contact surface of the contact cylinder 44 to seal the seal. Even if the member 47 is fitted and the nozzle 1 is rotated, the chemical liquid does not leak from the space between the arm tube 45 and the fitting cylinder 42b and the contact cylinder 44, and the frictional resistance allows the chemical solution to have an arbitrary angle. I am trying to maintain it.

きる。With this structure, when spraying while traveling between trees, when the lever 54 of the upper cock 53 is switched to spray from the upper spray section F, the spray sections on the left and right are sprayed from below. It can be sprayed on the surface of the upper leaves of trees that cannot be sprayed with 17L and 17R.
Further, by loosening the knob screw 33 for fixing the extension pipe 30 and sliding the extension pipe 30 upward, spraying to a higher position is possible. By rotating it upwards as shown by the chain double-dashed line,
The drug solution can be sprayed upward, and the spray height of the drug solution can be increased. By rotating the nozzle 1 downward, the chemical liquid can be sprayed downward.

きる。Since the present invention is constructed as described above, it has the following effects. That is, by disposing the upper spraying section above the rear part of the airframe as described in claim 1, it is possible to spray from the upper part of the tree, and the spraying can be performed only by spraying from the side and the lower side with the swing spraying section. It will be possible to spray even on areas that cannot be covered, and it is possible to eliminate uneven spraying on the branches and leaves. Further, while the oscillating sprayer sprays upward and sideways, the upper sprayer sprays backward from the rear of the oscillating sprayer. There is no overlap with the flow, it does not reduce the momentum of the spray, it is possible to improve the spraying performance on the whole tree, it is possible to spray a wide range from the top to the bottom of the tree in one stroke work. The reciprocating work such as double coating can be eliminated, and the working time can be shortened.
