Control work in agriculture is an important part, and it is known that it plays a crucial role in quality and yield of fruit trees harvested in fruit growing.

Generally, such a control work is based on a method in which a worker carries a personal transporting agent and distributes the agent in a small-sized plantation site. In a large-scale plantation site, a sprayer is mounted on a power source such as an automobile to rapidly spray the agent.

On the other hand, the uniformity of the spraying liquid, that is, the degree of uniformity of the chemical liquid sprayed on the leaves, stalks and pillars of fruit trees is a very important factor in the control work. However, according to the conventional spreader in which the chemical solution is sprayed at a uniform jetting speed irrespective of the distance, there is a difference in the degree of application of the chemical solution, that is, uniformity of application depending on the gap with the spreader, But also has a decisive influence on the growth of the plant.

Further, according to the conventional spraying apparatus for spraying the chemical liquid at a uniform rate, there is a problem that a part of the chemical liquid does not reach the fruit water and is wasted when the distance from the fruit water to be sprayed is long.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a space-regulating-type chemical solution dispensing apparatus capable of uniformly applying a chemical solution to fruit water to be sprayed and minimizing waste of unnecessary chemical solution.

According to the present invention, the above-mentioned object can be accomplished by a dispenser comprising: a dispensing part for dispensing a chemical solution supplied from a chemical solution storage part; An elevating part moving up and down to adjust the height of the jetting part; One end is connected to the lifting unit, the other end is connected to the injector, interval adjusting unit for adjusting the separation interval from the lifting unit to the spacing adjustable chemical liquid spray apparatus comprising a Is achieved by

A sensing unit sensing a distance between the dispensing unit and the object to be dispensed; And a controller for receiving the measured distance from the sensing unit and adjusting a distance between the object and the dispensing unit.

In addition, the control unit may control the injection speed of the chemical liquid from the injection unit.

In addition, the spraying unit is rotatably connected to the end of the gap adjusting portion, a pair of spraying boom to inject the chemical liquid toward different directions to form a slope; And a spray boom pivot member configured to adjust a rotation angle between the gap controller and the spray boom.

In addition, the pair of jet boats may include a first jet boom unit and a second jet boom unit, which rotate independently of each other.

The second angle portion may include a first gear coupled with the first rotating boom unit so as to cooperate integrally with the first rotating boom unit; And a second gear coupled to an end of the second rotating boom bar so as to be engaged with the first gear so that the second rotating boom bar interlocks with the first rotating boom bar.

According to the present invention, there is provided a space-regulating-type chemical liquid spraying apparatus capable of maintaining a constant distance from the fruit water by actively controlling the distance between the spraying target fruit and water.

In addition, by sensing the separation distance from the fruit number and spraying the chemical solution at the optimum speed, unnecessary chemical solution can be prevented from being wasted, and the chemical solution can be uniformly applied to the fruit water.
