The present invention relates to a film coating apparatus for performing a mulching cultivation technology, and more particularly, to a film coating apparatus that allows the operator to immediately recognize whether the vinyl or paper film is exhausted while using the film coating apparatus.

Recently, the use of pesticides has been announced to be harmful to the human body, the damage caused by the use of pesticides continues to continue. In response, the necessity for organic farming without pesticides is being emphasized, and the growing method of organic farming is becoming more and more popular. In addition, the Ministry of Agriculture and Forestry is promoting the Integrated Insect Pest Management Measure (IPM), which reduces pesticide use by 30% by 2004 and 50% by 2010, and the spread of eco-friendly cultivation technology that meets IPM technology measures is becoming important.

In response to the necessity of reducing the use of pesticides in rice farming, an eco-friendly cultivation method using no pesticides in rice or other crops is currently being developed, and various methods are being implemented.

One of these environmentally friendly cultivation methods is mulching cultivation technology.

In general, when the crop is grown, the material covering the surface of Gyeonggi soil is called mulch, and the farming method using the mulch is called mulching. In the past, rice straw, barley straw, grasses, etc. were used as mulching materials. Recently, vinyl films and paper films such as polyethylene and polyvinyl chloride are used. Mulching is carried out for the purpose of preventing soil erosion, maintaining soil moisture, controlling temperature, controlling weeds, preventing soil infectious germs, and preventing soil contamination.In recent years, mulching has been used to increase the temperature and to suppress the growth of weeds. .

In Korea, mulching cultivation technology is applied to the cultivation of crops including potatoes, radishes, onions, and fruits such as citrus fruits. Mulching cultivation technology has contributed greatly to the growth promotion and fruit yield increase in the cultivation of these, and furthermore, it is being applied to the cultivation of mushrooms and horticultural plants, and its scope of application is expanding day by day.

Conventional film coating apparatus is used to be mounted on a rice transplanter or a tractor, and serves to coat the film (including vinyl, paper) on the field or paddy field according to the movement of the rice transplanter. The film coating device coats the film in a wide field or paddy field using a film of about 1.5 ~ 2m width, and the film coating device coats the film one by one.

However, the film coating apparatus is generally mounted on the back of the rice transplanter or the tractor, the operator has a problem that it is difficult to check the film coating process from time to time because the operator operates while looking at the front. The operator may not be able to continue working without knowing that the film is exhausted, or may distract the operator without having to have the worker check the state of the film at all times. This inconvenience may lead to an accident during work, and may cause a reduction in the efficiency of the film coating apparatus.

The present invention is to solve the above problems, an object of the present invention is to provide a film coating apparatus that the driver of the rice transplanter and tractor can easily grasp whether the coating film is exhausted.
