[Operation of the invention]
[Invention of Claim 1]
The chemical spraying device sprays a chemical solution for sterilization, disinfection, and the like while moving along plants such as strawberries and other crops that are cultivated in a tall or fence-like manner.

  When the upper telescopic fold is extended and the lower telescopic fold is contracted, the first arm and the second arm are substantially V-shaped with the upper portion opened. Accordingly, the chemical spraying means attached to the first arm and the second arm, respectively, is also substantially V-shaped with the top open when viewed from the front of the chemical spraying apparatus, and the chemical is obliquely below the plants on both sides of the chemical spraying apparatus. Sprayed on. See FIG.

  When the upper telescopic folds are contracted and the lower telescopic folds are extended, the first arm and the second arm are in an inverted substantially V shape with the bottom opened. Accordingly, the chemical spraying means attached to the first arm and the second arm, respectively, has an inverted substantially V shape with the bottom opened as viewed from the front of the chemical spraying apparatus, and the chemical is oblique to the plants on both sides of the chemical spraying apparatus. Scattered upward. See FIG.

  The first arm and the second arm are set to have a substantially C shape or an inverted substantially C shape with an appropriate angle when viewed from the front of the chemical spraying device by appropriately expanding and contracting the upper and lower extension rods. It is also possible.

  Furthermore, it is not always necessary to expand and contract the upper and lower telescopic folds symmetrically. It is also possible to set the first arm and the second arm at different angles when viewed from the front of the chemical liquid spraying device by expanding and contracting the upper and lower telescopic folds separately to the left and right.

  When the upper telescopic rod and the lower telescopic rod are expanded and contracted in the same manner, the first arm and the second arm are in a vertical state parallel to each other. Accordingly, the chemical solution spraying means attached to the first arm and the second arm are also in a vertical state parallel to each other, and the chemical solution is sprayed horizontally on the plants on both sides of the chemical solution spraying device. See FIG. 6 and FIG.

  The distance between the first arm and the second arm is adjusted while maintaining the first arm and the second arm in a vertical state parallel to each other by extending and contracting the upper and lower extension rods in the same manner. It is also possible.

  Needless to say, the chemical liquid may be sprayed only by the chemical liquid spraying means of either the first arm or the second arm.

  As described above, with respect to plants such as strawberries and other crops cultivated in the form of tall cultivation or in the shape of a fence, the first arm and the second arm are set at a desired angle when viewed from the front of the chemical spraying device, or The chemical solution can be sprayed in a state of being perpendicular to each other and having a desired interval.

[Invention of claim 2]
By rotating the first arm and the second arm in the vertical direction about the horizontal axis of the left and right direction of the carriage as the center of rotation, the chemical solution spraying means is viewed in the longitudinal direction of the chemical solution spraying device when viewed from the side of the chemical solution spraying device. Can be set to angle. See FIG. For example, the chemical solution spraying means can be used in a desired forward tilt posture.

[Invention of claim 3]
The support arm can be set to a desired angle in the front-rear direction of the chemical solution spraying device as seen from the side of the chemical solution spraying device by extending and contracting the support arm telescopic hooks. When the support arm is set to a desired angle in the front-rear direction of the chemical liquid spraying device, the first arm and the second arm also have a desired angle in the front-back direction of the chemical liquid sprayer. In other respects, the invention of claim 3 has the same function as the invention of claim 2.

[Invention of claim 4]
Since each expansion / contraction hook is formed by connecting a plurality of links via a connecting pin, it can expand and contract.

[Invention of claim 5]
The chemical liquid is branched and supplied to each chemical liquid spraying means via a chemical liquid supply hose connected to a chemical liquid supply source, and then sprayed.
