Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to an underground irrigation hose embedded apparatus,

The present invention relates to an underground irrigation hose burial apparatus.

Generally, the drop hose is installed for the purpose of supplying water to the crop, and the drop hose is formed with a flow path having an inlet and an outlet at regular intervals. The inlet is connected to the inner passage of the hose and the outlet is connected to the outside.

Water flowing through the internal passageway of the drop hose flows into the inlet, flows along the flow path, and is discharged to the outlet. The water discharged to the outlet is supplied to the crop, and the water is supplied to the crop by dripping at the outlet, And supplied to the crop.

On the other hand, in order to cultivate the crops using the vinyl house, it is intended to cultivate the crop regardless of the season. In particular, the crop is a crop which is affected not only by temperature but also by geothermal heat.

Therefore, in order to cultivate the crops in the vinyl house during the low temperature season, it is necessary not only to keep the temperature of the vinyl house warm, but also to maintain the warm temperature of the field itself so that the growth of the crop becomes strong and the crop can be harvested. It is ideally high and it is necessary to cool it. In order to do this, the underground cold liner hose or the drop hose is buried in the plastic house.

In the past, in order to burrow underground cooling and heating hoses or drip hoses in a plastic house, it is necessary to drill a field by using a tractor and then to bury the cooling or heating hose or drip hose. After the hiring of the cooling or heating hose or the drop hose, I had buried the air-conditioning hose or the drop hose as a burying work.

However, in the conventional method of land excavation, it takes a lot of time and manpower to bury the hose for cooling and heating or drip hose, and there is a problem that the burden on the burden of the hose for heating and cooling is high and the economic burden is increased. Especially, There is a problem in that the burial work is further delayed because the burdening work is performed in the inside.

An embodiment of the present invention is to provide an underground irrigation hose burial apparatus which is connected to a towing vehicle such as a tractor and moves along a traveling direction to automatically feed a hose into the ground.
