A boom main body 2, in which a telescopic boom 1 that can be extended and contracted in a plurality of stages is retractably provided, is attached to a sprayer main body (not shown) which is movable and has a chemical solution tank. The telescopic boom 1 includes a first-stage boom 1a that can be stored in a boom body 2, and a second-stage boom 1b that can be stored in the first-stage boom 1a.
Jet pipes 4 and 5 each having a plurality of jet ports 3 are arranged in the first and second stage booms 1a and 1b, respectively.
For example, the conventional device in which the jet pipe 5 and the chemical tank are connected is hung on a hose roller 6 that is pivotally supported at the tip of the first stage boom 1a of the telescopic boom 1, and the base is connected to the chemical tank. The tip of a normal flexible hose 7 is connected to the base of the jet pipe 5 of the second boom 1b, and the second boom 1b connects to the first boom 1a.
When stored in the first boom 1a, the hose 7 is also bent via the hose roller 6 and is stored in the first stage boom 1a.

ない。 Figure 2 shows a device based on this invention with two telescopic booms.
This is a schematic side view showing what has been done to a boom sprayer that is extendable and retractable in stages. In the drawing, 10 is a boom body that is equipped with a chemical tank (not shown) and that is attached to a sprayer body that is movable on wheels. A telescopic boom 11 that is extendable and retractable in two stages is attached to the boom main body 10 so that it can be stored within the boom main body 10. The telescopic boom 11 includes a first-stage boom 11a that is storably mounted on the boom body 10, and a second-stage boom 1 that is storably mounted inside the first-stage boom 11a.
1b. And the boom body 10,
The first-stage boom 11a and the second-stage boom 11b are provided with jet pipes 13, 14, and 15, respectively, in which a plurality of jet ports 12 capable of spraying a chemical solution are arranged at appropriate intervals. In the boom sprayer constructed in this way, for example, the jet pipe 15 and the chemical liquid tank are connected by the device according to this invention, and the chemical liquid is supplied to the nozzle 1.
2, as shown in FIG. 2, base end struts 16, 18 and distal end struts 17 are installed at the base end and distal end of the boom main body 10 and the first stage boom 11a of the telescopic boom 11, respectively. , 19 are erected while being reinforced by reinforcing members 16a, 17a, 18a, 19a, and these base end supports 16,
Wires 20 and 21, which serve as rail means, are installed in a stretched state between the wires 18 and the tip supports 17 and 19, respectively. and these wires 20,2
1 have coiled coil hoses 22 and 23, respectively.
are telescopically suspended, and the coil hoses 22, 23
are connected to each other, and the coil hose 22
The base end of the coil hose 23 is connected to a chemical liquid tank via a pressure feeding means (not shown), and the distal end of the coil hose 23 is connected to the base end of the jet pipe 15. With these configurations, the jet pipe 15 is connected to the chemical tank, the first stage boom 11a is housed in the boom body 10, and the second stage boom 11b is connected to the first stage boom 11.
Even when stored in the coil hose 22, 2
3 are contracted in the proximal direction along the wires 20 and 21, respectively, and are not bent. Note that the jet pipe 14 attached to the first stage boom 11a can be connected to the chemical tank by connecting it to the base end of the coil hose 23, and even in this case, the first stage boom can be connected to the boom. When housed in the main body 10, the coil hose 22 is contracted along the wire 20, and the coil hose 22 is not bent.
