It is a top view of the liquid spraying apparatus for greenhouses of FIG. FIG. 3 is a view taken along the line VI-VI of FIG.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, the greenhouse H has a plurality of cross beams B that are horizontally provided at the same height position above the greenhouse H with mutual spacing. The liquid spraying device 1 sprays liquid while self-propelling above the greenhouse H along a pair of rails 3 supported by the cross beam B. Reference numeral 6 denotes a traveling body that runs on the rail 3, and reference numeral 8 denotes a multi-head ejection nozzle that is supported under the traveling body 3 by an elevating pole 7. The multi-head ejection nozzle 8 is connected to the liquid storage tank T outside the greenhouse H by an infusion hose 5. The infusion hose 5 is wound around the hose reel R during extension, connected to the pump P via the control valve V, and manually or automatically so as to enter or leave the greenhouse H according to the movement of the traveling body 3. It is unwound and rewound on the hose reel R.

Hereinafter, the liquid spraying device 1 will be described in more detail. As is well shown in FIGS. 2 and 3, the liquid spraying device 1 includes a pair of rail support members 2 supported on each cross beam B of the greenhouse H at intervals on the left and right, which is an extension direction thereof, and a rail support. A pair of left and right rails 3 supported at the lower part of the member 2 so as to extend horizontally in the direction orthogonal to the cross beam B, and a tank T via the infusion hose 5 while being supported by the rails 3 and running along the rails 3 by themselves. It is provided with a sprayer 4 for spraying "liquids such as pesticides sent from".

As is well shown in FIG. 3, each pair of rail support members 2 has an upper connecting portion 21 fixed to each cross beam, an arm portion 22 hanging downward from the connecting portion 21, and the arm portion 22. It is provided with a rail support portion 23 extending from the lower portion toward the other rail support member 2.

The pair of rails 3 made of steel pipe material are fixed by a U band 24 on the rail support portion 23 of each pair of rail support members 2.

The sprayer 4 has a traveling body 6 suspended from a rail 3 and a traveling body 6, an elevating pole 7 hanging from the traveling body 6, and a multi-head spray nozzle 8 supported so as to extend horizontally below the elevating pole 7. Equipped.

The traveling body 6 mounts the power supply battery 62, the drive motor 63, and the control device 64 of the drive motor 63 on the body frame 61. The control device 64 is provided with a wireless transmitter / receiver, receives a signal from a controller outside the greenhouse, starts / stops the drive motor 63, switches forward / reverse rotation, etc., and reaches the end in a preset traveling direction. It is detected by a sensor such as a damper limit switch (not shown) and a ringing signal is sent to the controller side.

A pair of left and right drive wheels 65 and driven wheels 66, which are arranged in the front-rear direction so as to roll on the rail 3, are provided at the four corners of the fuselage frame 61. The support shafts 65a and 66a of the drive wheel 65 and the driven wheel 66 are supported by bearing portions 67 provided so as to rise from the left and right side portions of the airframe frame 61 to a position higher than the rail 3 inside the pair of rails 3. Rail. The support shaft 65a of the drive wheel 65 is connected to the drive motor 63 via the transmission mechanism 68.

The elevating pole 7 hangs down from the traveling body 6 and can be expanded and contracted downward. Thereby, the height position of the multi-head spray nozzle 8 supported downward can be adjusted according to the height of the plant growing below the multi-head spray nozzle 8. The elevating pole 7 includes an upper support pipe 71 supported by the body frame 61 of the traveling body 6, and a lower support pipe 72 inserted into the support pipe 71 so as to be detachable and the support position in the vertical direction can be adjusted. The upper support pipe 71 penetrates the airframe frame 61 in the vertical direction at the upper end portion, and the lower portion protrudes downward from the airframe frame 61. Therefore, the upper portion of the lower support pipe 72 inserted into the upper support pipe 71 can be projected upward of the airframe frame 61, and the height thereof can be raised as necessary. The lower support pipe 72 is provided with an angle adjusting metal fitting 73 at the lower end.

The traveling body 6 is provided with a leg member 69 extending downward longer than the downward protruding length of the upper support pipe 71 so that the traveling body 6 can be lowered to the ground and stably arranged with the lower support pipe 72 removed. Further, the traveling body 6 can be lifted by holding the leg member 69 and easily placed on the rail 3.

A pair of multi-head spray nozzles 8 are provided below the lower support pipe 72 via the nozzle support arms 9. Each of the pair of nozzle support arms 9 is supported by the angle adjusting metal fitting 73 at the base end portion, and the extension angle in the horizontal direction can be adjusted integrally with the multi-head spray nozzle 8. By folding the nozzle support arm 9, it is configured so that entry and exit from the narrow entrance of the greenhouse H can be easily performed.

The liquid spraying device 1 can spray liquids such as pesticides and water on plants in the greenhouse H by applying various known control systems and operating the liquid spraying device 1.

For example, with the traveling body 6 mounted on the inlet side end of the rail 3, an operator outside the greenhouse H wirelessly sends a start signal from the controller to the control device 64, and opens the control valve V to pesticide or the like. The liquid is sent to the multi-head spray nozzle 8 via the infusion hose 5, and the liquid is sprayed from the multi-head spray nozzle 8 onto the plants below while the traveling body 6 is running on the rail 3. During this time, the infusion hose 5 is sequentially pulled out from the hose reel R.

When the traveling body 6 reaches the end of the rail 3, a sensor such as a damper limit switch detects this and the drive motor 63 stops, and at the same time, the controller at the operator's hand outside the greenhouse H is sounded to reach the end. Inform. In response to this, the operator closes the valve V, stops the infusion, returns to the control device 64, and issues a running command.

Similarly, when the traveling body 6 reaches the inlet side end of the rail 3, the sensor detects this and the drive motor 63 stops, and at the same time, the controller at the operator's hand outside the greenhouse H is sounded to reach the rail 3. Inform. The infusion hose 5 is automatically or manually rewound on the reel R. If necessary, the operator removes the traveling body 3 from the rail 3 and mounts it on the rail 3 in another adjacent row to perform the same spraying operation.
