FIG. The rotating means by the bearing 37 is preferable because the boom 3 having the spray nozzle 2 can be easily rotated manually and has excellent operability, but in the present invention, rotating means other than the bearing 37 can be used. For example, with the screws and nuts used to fix the boom 3 to the base 16 being loosened, the boom 3 is moved from the 0 degree state (the state shown in FIGS. 1A and 1B) to 90 degrees. For example, the boom 3 is fixed to the base 16 at a position of 90 degrees by tightening screws and nuts after being rotated to a state (states (a) and (b) in FIG. 5).

  Further, the boom 3 is rotated by using a flexible material such as a plastic hose for the introduction pipe 11 and the supply pipe 13 so that the length of the hose can follow the rotation of the boom 3. This can be done easily by adjusting the shape.

  As shown in FIG. 5, by rotating the boom 3, the direction of the longitudinal direction of the boom 3 can be changed to the traveling direction of the self-propelled work carriage 7. The device can be easily run. For example, in a state as shown in FIG. 1, a liquid spraying device that could not enter or exit the house due to the length of the boom 3 can be moved or moved between the houses by rotating the boom 3 as shown in FIG. 5. It becomes possible. Thus, since the liquid spraying device of this embodiment is convenient to handle, not only can the efficiency of the liquid spraying operation in the house be improved, but also the usability of the liquid spraying device can be improved.

As shown in a frame surrounded by a dotted line, the boom 3 is divided at both ends of the folding portion, and each of the divided booms has a structure connected by a hook 38. The sliding bracket 39 is a jig used to mechanically connect the booms divided at the folding position to each other in a state before the boom is folded, and is a groove provided on at least one side surface of the boom 3. Has the function of sliding. Accordingly, it is possible to prevent the behavior and position deviation of the boom from being folded at the time of spraying the liquid. When the boom 3 is folded, the boom 3 can be folded by sliding the slide-type metal fitting 39 to one of the divided booms.

  As a folding mechanism of the boom 3 used in the present invention, a joint can be used in addition to the above-described hinge 38. Examples of the joint include a joint having a bellows type structure in which a female concave portion and a male convex portion are provided at both ends, and the middle between both ends can be bent. Further, the boom 3 is divided into a plurality of parts, and a female concave part and a male convex part are provided at both ends, and both ends are inserted. In that case, in order to prevent the plurality of booms divided when the boom is folded, for example, a method of inserting a spring-type connection chain into the plurality of divided booms can be employed.

  In this embodiment, it is preferable to use a flexible hose or pipe 14 connected to the spray nozzle 2 so that the boom 3 can be easily folded. In addition, as shown in FIG. 6, hot water or chemicals are provided by individually installing hoses or pipes 14 according to the length of the divided boom and connecting individual supply pipes 13 to the respective hoses or pipes 14. It is also possible to adopt a method of supplying In that case, the hose or the pipe 14 need not be particularly flexible, and may be mechanically fixed to the divided boom.

  In the present invention, there are one or more means for folding the boom 3 at a desired position. Here, the boom folding means is used not only when moving or moving the liquid spraying apparatus, but also when the length of the boom arm can be adjusted according to the scale of the house and the spraying range.
