Description

DETAILED DESCRIPTION OF THE INVENTION The present invention makes it possible to expand the spraying range by moving a sprayer such as a spraying nozzle by moving a moving cable, and is suitable for agricultural, snow melting, cooling, industrial, and fishery applications. This invention relates to a spraying device that can be used in a wide range of industrial fields.

Conventionally, various types of spraying devices have been provided in which a sprayer such as a spraying nozzle is configured to move. For example, a chemical dispersion device as described in Utility Model Publication No. 1100/1973, or
There are automatic watering devices such as those described in the publication.

The former is a mobile vehicle that is equipped with a rotating wheel movable along the frame on a frame that can be used for a track such as a frame that extends from one end to the other in the greenhouse. A jet pipe is attached to the mobile vehicle in a removable manner, and a hose is hung between a rotary wheel provided facing the side end of the frame and a hose winding mounted on a traveling vehicle located outside the greenhouse. A part of the stretched cable is fixed, and a flexible tube is connected to the squirt tube, which is wound around the hose and communicates with a supply source of medicine, etc.; A guide rail is provided at the top of the tank so that the sprinkler rolling wheel casing can be moved by an electric motor housed inside.
This electric motor rotates in a timed manner in conjunction with a timer clock, and a forward/reverse rotation device is installed in parallel to rotate the electric motor back and forth, and when the electric motor is rotating, it is attached to the bottom of the water sprinkler rolling casing. The structure is such that water is sprayed into the germination tank from a fountain pipe to cool the germination heat of the bean sprouts.

However, in both of these spraying devices, a mobile vehicle equipped with a spout pipe and a water rolling vehicle casing equipped with a spout pipe can be moved back and forth above the bean sprout germination tank in the greenhouse via tracks and guide rails. In order to reliably support these tracks and guide rails, which are quite heavy, the framework and supports must be made sturdy, and the greenhouse itself must also be constructed to be quite sturdy. There were some difficulties, such as the need for reinforcement. Moreover, the structure of the device itself is complicated and the entire device is large-scale. Therefore, the installation work of the device becomes quite troublesome, and the burden of equipment costs increases, resulting in disadvantages such as poor economic efficiency.

Therefore, in the present invention, a driving side mechanism A having a driving pulley 1 is disposed above one end of the spraying place, and a driven side mechanism A having driven pulleys 5 and 6 above the other end of the spreading place. Mechanism B is arranged, an endless annular moving cable 10 is wound under tension around the driving pulley 1 of the driving side mechanism A and the driven pulleys 5 and 6 of the driven side mechanism B, and the spreader 12 is wound around the moving cable 10.
Attach the dispersion body 11 comprising
1, the tip of a hose 13 that supplies the spray liquid is connected to the moving cable 10, and the hose 13 is suspended from the moving cable 10 via the hose support ring 14, so that the rotational force of the driving pulley 1 driven by the driving mechanism A is transferred to the moving cable. 10, the movable cable 10 rotates, and the hose 13 can follow the dispersing body 11, which can freely move back and forth between the driving mechanism A and the driven mechanism B as the movable cable 10 moves. The above-mentioned difficulties can be solved by forming the movable cable 10 as follows, and adding a loosening prevention mechanism C that can prevent the movable cable 10 from hanging down due to the weight of the dispersion body 11 and the like.

Hereinafter, the present invention will be explained with reference to illustrated examples.

The spraying device of the present invention comprises a driving pulley 1 driven and rotated by a motor, and intermediate pulleys 2 and 3 rotatably supported above and below the driving pulley 1 at appropriate intervals. A is disposed above one end of the spraying area via a support 4, and is provided with driven pulleys 5 and 6 rotatably supported vertically at appropriate intervals. B
is placed above the other end of the spraying area via a support 4. Then, the driving pulley 1 of the driving side mechanism A
An endless annular moving cable 10 is wound under tension around the intermediate pulleys 2, 3 and the driven pulleys 5, 6 of the driven side mechanism B, and a spreading body 11 is provided with a spreading device 12 as appropriate on the moving cable 10. is attached in a fixed manner, the tip of a hose 13 for supplying the spray liquid to the sprayer 12 is connected to this sprayer 11, and the hose 13 is suspended from the movable cable 10 via a hose support ring 14. There is. That is,

By the way, the moving cable 10 is connected to the driving side mechanism A.
As the distance between the movable cable 10 and the driven mechanism B increases, the sag increases, so a loosening prevention mechanism C is provided to prevent the movable cable 10 from sagging. That is, the loosening prevention mechanism C in FIG.
The upper moving cable 10 is always pulled up by the upper moving cable 10 to prevent loosening of the moving cable 10, and the loosening prevention mechanism C in FIG. Mechanism B
The moving cable 1 is moved by the guide car 17 arranged approximately in the center of the
0 to prevent the moving cable 10 from hanging down.
The loosening prevention mechanism C in the figure has an intermediate wheel 18 on which two cables can be hung approximately in the center of the driving side mechanism A and the driven side mechanism B, and the intermediate wheel 18 and the driving side mechanism It is divided into a moving cable 19a that is wrapped around A, and a moving cable 19b that is wrapped around the intermediate wheel 18 and driven side mechanism B,
It is formed to prevent the moving cables 19a, 19b from hanging down. In the embodiment described above, two sets of scatterers 11 are required as shown in FIGS. 5 and 6, respectively. In addition, the loosening prevention mechanism C in FIG. Multiply by 24 to move cable 10
It is formed in such a way as to prevent it from sagging. In the figure, 25 is a running pulley that is rotatably supported by the dispersing body 11 and runs freely on the movable cable 10, and 26 is a fixed part that connects the dispersing body 11 and the movable cable 10.

The hose 13 is designed to prevent bending or twisting of the hose 13 itself from cutting off the supply of the spray liquid midway, and is designed so that it can smoothly follow the movement of the spray body 11. There is. Furthermore, the sprayer 12 installed on the sprayer 11 is configured to automatically rotate using the reaction force generated by spouting the spray liquid, so that a good spraying condition can be obtained over a wide area. A rotary sprayer may be used, or a spray nozzle may be used, and the number and installation position of the spray nozzles will be determined depending on the purpose of use, etc. to achieve the best spraying condition of the spray liquid. It's fine if it's something like that.

In addition, as shown in FIG. 2, the present invention arranges the moving cables 10 in a plane substantially parallel to each other, and transmits the rotational force of the motor of the drive side mechanism A through the drive shaft 20 connected by the connection joint 21. The transmission is transmitted to the driving side mechanism A1 which is not equipped with a motor, and all the moving cables 10 are moved.The spraying liquid is forcibly sent to the hose 13 by a pump or the like, and the spraying liquid is transmitted to the moving cable 10
It is also possible to form the sprayer 12 of the sprayer 11 attached to each sprayer to spray the powder, and in this way it becomes possible to spread the powder over a wide range.

Therefore, the spraying device of the present invention has a driving side mechanism A that includes a driving pulley 1 above one end of the spraying location.
