Description

[0001] The present invention relates to a roof type chemical liquid spray device,

[0001] The present invention relates to a ceiling-shaped chemical liquid spraying apparatus, and more particularly, to a ceiling-shaped chemical liquid spraying apparatus, in which a drive motor is reversed within a certain angle range, The present invention relates to a ceiling-shaped chemical liquid spraying apparatus.

Generally, the term "chemical liquid spraying apparatus" refers to an apparatus for spraying a liquid substance having a weak liquid including water mainly through pressure. Various principles have been adopted for spraying a chemical liquid of such a chemical liquid spray apparatus.

The most basic method of the above-described chemical liquid spraying apparatus is that the chemical liquid is directly pumped by the pump and the chemical liquid is sprayed by the nozzles at the end, but it is difficult to spray a fine chemical liquid Problems and difficulty in spraying over a large area.

In another method of the above-described chemical liquid spraying apparatus, there is a method in which the chemical liquid inside the chemical liquid tank is sucked by the pressure difference between air passing through the venturi tube at a high speed and injected together with air. In this case, There is a disadvantage in that the ratio of the chemical liquid sprayed together is not constant and the user can not easily control the ratio.

On the other hand, when cultivating crops throughout the year regardless of the season in the house, the insecticide, which is an insect repellent and the nutrient for the nutrition of the crops, is sprayed continuously to increase the productivity.

However, as described above, the pest control work for the crops in the enclosed house is a troublesome and time-consuming operation because the chemical solution is sprayed while carrying a heavy atomizer on the back of the user. Particularly, in the summer season, the temperature in the house rises, causing the operator to suffer pain in the control work.

In addition, the above-described prior art techniques can be applied to a small amount of crop when spraying a tank containing a chemical solution on the back, but it takes a long time to inject the sprayed liquid into a large amount of crops. There is a disadvantage that the spray liquid must be carried on the back for a long time.

In addition, in the case of using the chemical liquid as described above, when the chemical liquid is supplied and used, it must be sprayed on the crop while carrying the sprayer having the spray nozzle, so that the chemical liquid penetrates the human body through the skin or the respiratory system, Serious problems have been raised.

At this time, the detecting portions 170 and 170a are formed on the line formed by one of the pin coupling grooves 152 and 152a from the center of the angle adjusting rings 150 and 150a. This facilitates calculation of the angle between the two detectors 170 and 170a to be adjusted.

1, 4 and 5, the detection sensor 190 detects presence or absence of the detection unit 170 in the proximity of the detection units 170 and 170a in the configuration of the drive motor rotation control means described above. As shown in the figure, the detection units 170 and 170a of the angle adjustment rings 150 and 150a are installed on the upper surface of the lower case 122, So that the forward and reverse drive of the drive motor 180 is performed.

4, the forward rotation of the support shaft 110 is performed in accordance with the forward driving of the drive motor 180, so that the lower end of the support shaft 110 is fixed to the upper end fixing ring 140 of the support shaft 110 When the detecting unit 170 on the angle adjusting ring 150 is moved to the front side of the detecting sensor 190, the detecting sensor 190 detects the detecting unit 170a.

When the presence or absence of the detection unit 170 is detected by the detection sensor 190 as described above, the drive motor 180 is driven in the reverse direction according to the detection signal to rotate the support shaft 110 in the reverse direction, When the detection unit 170a on the upper side angle adjustment ring 150a is moved to the front side of the detection sensor 190 while the reverse rotation of the detection unit 170 is being performed and the presence or absence of the detection unit 170a is detected by the detection sensor 190 The drive motor 180 is again driven in the forward direction.

When the drive motor 180 is driven through the application of the power as described above, the support shaft 110 and the chemical liquid sprayer 10 are rotated forward by the forward rotation of the drive motor 180, . At this time, if the one side detecting unit 170 or 170a is moved to the front side of the detecting sensor 190 and the presence or absence is detected, the driving motor 180 is rotated in the reverse direction.

Accordingly, as the drive motor 180 is rotated in the reverse direction as described above, the support shaft 110 and the chemical liquid sprayer 10 are also rotated in the reverse direction, thereby spraying the chemical liquid. At this time, if the other detector 170a or 170 is moved to the front of the sensor 190 and the presence or absence is detected, the drive motor 180 is rotated forward.
