[0002]

2. Description of the Related Art Conventionally, a medicine tank is placed on a carrier of a carrier,
In a chemical spraying machine for controlling, which is equipped with an engine, a pump and the like, and is equipped with a spray duct, as shown in Japanese Utility Model Laid-Open Publication No. 7-30679, it has an annular shape along the periphery of the exhaust port of the spray duct. A plurality of nozzles were provided at the site.

[0003]

However, in such a structure, when spraying a controlling agent, even if the sprayed chemical is made denser to improve the adhesion accuracy to fruit trees and the like, It is difficult to mix with the air from the spray duct because it is not smooth.In addition, even if the air volume is increased to extend the spray reach, the air blows turbulently on the downstream side immediately after the motor of the axial fan and sprays far away. In addition, it is difficult to perform the spraying, and because a large amount of the spray is transported around the blast, it is difficult to efficiently send the medicine over a long distance.

[0004]

It is intended to be able to spray, and therefore, a medicine tank, an engine, a pump and the like are provided on a carrier of a carrier, and a spraying machine is equipped with a spray duct. A flow fan is provided, a conical rectifier is provided on the downstream side of the axial flow fan, the free end of which is tapered toward the downstream side, and an annular liquid supply pipe is provided in the vicinity of the exhaust port of the spray duct. The liquid supply pipe is provided with a plurality of peripheral nozzles, and a central nozzle is provided at the center of the liquid supply pipe downstream of the rectifier, and the liquid supply pipe and the central nozzle are provided. The door is connected through a plurality of support pipes, it is obtained by constituting the liquid medicine at least one of the support pipe of the support pipe so as to supply to the central nozzle.

[0005] Another object of the present invention is as follows.
It is to be able to spray effectively by adapting to the state of the fruit tree on the side receiving the spray of the chemical and the distance to the spray duct,
For this reason, a valve device capable of stopping the supply of the chemical solution to the central nozzle is provided in the vicinity of the central nozzle, and the medicine can be sprayed only by the peripheral nozzle and the central nozzle or the peripheral nozzle.

A four-way panel switch 26 that can turn and operate the exhaust port 5a in the vertical direction while rotating about the horizontal shafts 23, 23, and the pump 4. Adjusting lever 27 which can perform the chemical amount adjusted by operating the pump motor was to deploy a control lever 28 for performing speed control of the engine 3. A rectifying body (cone) 33 serving as a conical air blowing guide body is provided from the front of the fan motor 24 so that the downstream side of the air blowing is tapered.

An annular liquid supply pipe 7 extending along the vicinity of the distal end side of the air discharge port 5a of the spray duct 5 is supported by a plurality of support pieces 29 and installed. , The surrounding nozzles 8... Protrude forward, respectively, and the liquid supply hose 19 is connected to the spray duct 5.
And is extended by being supported by the support 30 and connected to the connector 34 to communicate with the liquid supply pipe 7.

At the center of the inside of the liquid supply pipe 7 and downstream of the flow regulating body 33, three support pipes 10a, 10b, 10
c, and the inside of the liquid supply pipe 7 and the inside of the connecting body 31 are connected to each other via one of the three supporting pipes 10a. A valve device 11 for opening and closing a ball cock type valve 11b by a lever 11a is provided between the central nozzle 9 and a central nozzle 9 having a hood 32 attached to the front thereof. An electromagnetic valve type that can be remotely operated from the handle portion 15 or the like may be used. In addition, you may comprise so that a chemical | medical solution may also pass through the said support pipes 10b and 10c.

Therefore, while being moved by the transport vehicle A, the spray duct 5 swings its head in the left and right directions and changes its direction in the vertical direction, so that the medicine can be sprayed in a house, an orchard, a street tree, and the like. When the valve device 11 is opened,
The chemical solution can be ejected from each of the peripheral nozzles 8 and the central nozzle 9, and the exhaust port 5 of the spray duct 5
In addition to the chemical liquid jet from each of the peripheral nozzles 8a, a chemical liquid with a high density can be sprayed while the chemical liquid is jetted from the central nozzle 9 at the center where the wind speed is increased by the conical rectifier 33, The accuracy of adhesion to fruit trees and the like can be improved, and the agent can be efficiently sent to long distances.

As in the above embodiment, the central nozzle 9
Is projected forward from each of the peripheral nozzles 8 and the hood 32 is attached, so that the spraying of the dense chemical solution and the sending of the chemical solution over a long distance can be performed even more efficiently.

When the valve device 11 is closed, a chemical solution can be ejected only from each of the peripheral nozzles 8, so that the spraying state can be changed, and the side of the side receiving the chemical spray can be changed. It can be sprayed effectively by adapting to the state of the fruit tree and the distance to the spray duct 5. In particular, when controlling trees that are heavily damaged by insect pests, it is preferable that chemical liquid be ejected from both the peripheral nozzles 8 and the central nozzle 9.
