Description

Cart House Sprayer

The present invention relates to a trolley sprayer for a vinyl house, and more particularly, to a product that improves the disadvantages of the existing automotive pesticide sprayer and the disadvantages of a general power pesticide sprayer sprayed on the back. In the case of spraying pesticides, the present invention relates to a chemical sprayer for a plastic house cart equipped with a free nozzle stand and a driving engine so that it can be sprayed easily and quickly.

In recent years, facility cultivation of crops is increasing to supply fresh crops regardless of season. Among them, vinyl houses have been used for cultivating crops for a long time.

Such a vinyl house is made of a predetermined shape and covered with a film for the vinyl house on the frame installed on the ground to cultivate crops by making the environment inside the vinyl house suitable for growing crops regardless of the season.

Conventionally, there has been a pesticide spraying truck that sprays pesticides on crops while traveling in paddy fields or fields, but the nozzle spraying stand is extended to the left and right to suit a wide range of agricultural lands, which is not suitable for a plastic house. Although it was applied to spray on crops by manually spraying on the back and moving paddy fields or field heads, there was a disadvantage that the worker was easily tired when working over a large area for a long time. In addition, the manual spraying method by humans has a risk of pesticide damage due to pesticides or inhaling pesticides to workers, and has been very cumbersome because the spray is continuously supplied with pressure for spraying pesticides. .

In addition, although a patent for a spraying vehicle for spraying chemicals on crops is registered in Korean Patent Publication No. 96-67, it is a self-propelled chemical spraying vehicle that uses a crawler to move by radio control. In a large area, there was a disadvantage that effective spraying was not performed.

Therefore, an object of the present invention is to solve the problems of the prior art as described above can be easily sprayed while driving the wheelbarrow in a plastic house, freely up and down, left and right so as to achieve a sufficient spreading effect It is an object of the present invention to provide a trolley sprayer for a plastic house having a moving spray nozzle stand and a moving nozzle.
