Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention mainly relates to fruit trees such as pears, grapes, kiwis and the like, as well as fruit trees such as tangerines, apples, cherries and plums, which are to be sprayed.
The present invention relates to a micro sprinkler automation system suitable for multipurpose use such as prevention of frost damage, prevention of sea breeze damage, prevention of volcanic ash, and irrigation.

[0002]

2. Description of the Related Art Conventionally, three types of systems, such as a manual spraying system, a speed sprayer system and a sprinkler system, have been employed for the above-mentioned applications. During the summer months when work is required, workers must wear poorly ventilated cutlers and masks to avoid chemical injury, and because of heavy labor, it is difficult for some people to hate this and quit. This is the current situation.

[0003] On the other hand, the method using a speed sprayer has the advantage that the adhesion of chemicals and the like to the back of the leaves is good because the tree branches are swung by the wind pressure generated by the blower. However, there is a problem that the driver is harmed by spraying a relatively large amount of medicine for a long time, and it is difficult to secure the driver. It has also been pointed out that the soil of the field is compacted by the wheel pressure of the speed sprayer.

[0004] Next, in the conventional general sprinkler system, it has been pointed out that, when spraying on a tree to be sprayed, the chemical adhesion to the back of the leaf is considerably poor. That is,
The conventional sprinkler method is ineffective, especially for controlling pests, which usually adhere to the back of leaves.

[0005]

SUMMARY OF THE INVENTION Here, the present invention is intended to make up for the disadvantages of the conventional systems, to eliminate the adverse effects of pesticides as much as possible, and to improve the effect of multipurpose use including prevention of frost damage. An object of the present invention is to provide a micro-sprinkler system which is a low-pressure, low-water-volume type, in which a required amount of pesticide can be applied for a long time, and a control effect by vertical movement can be greatly improved.

[0009]

According to the structure of the present invention having the above-described structure, the wire drum is periodically rotated forward and reverse at a predetermined speed via the driving means, whereby the wire drum is rotated. According to the configuration of claim 2, the slider moves up and down along the column as the wire rope constituting the wound closed circuit moves, and according to the configuration of the wire rope wound around the upper pulley. Then, the spray head moves up and down, so that, for example, a control agent is forcibly pumped from the supply source and ejected from the spray head in a timely manner, and the spray is uniformly applied to the front and back of the leaves of the tree to be sprayed.

The slider 2 moves up and down along the column 1. Therefore, the riser 5 fixed to the slider 2
The height of the jet head 6 changes due to the up and down movement of the riser. By appropriately selecting the height relationship with respect to the trees to be scattered, etc. A spraying liquid such as a liquid can be evenly spread on the front and back of a leaf to be sprayed.

As a practical problem, as shown in FIGS. 9 and 10, the pulley 3 guides the circumferential groove 3 for hanging the other end 9b of the wire rope 9 and the main wire rope 53 as shown in FIGS. Passing through the guide 55 provided on the top of the support column 1 is effective in preventing the wire rope 9 and the main wire rope 53 from entanglement.

[0024]

According to the micro sprinkler system of the present invention having the above-described structure, the drive means B sets a desired rotation speed and normal / reverse rotation timing, so that a relatively large field can be obtained. However, it is possible to spray chemicals at the same time evenly, and to spread the chemicals uniformly on the front and back of the leaves to be sprayed while reducing the amount of required chemicals, eliminating the contamination of the surrounding environment, and saving labor. It is possible to do.
