The present invention relates to a snow cultivation apparatus using a surface heating sheet, and more specifically, the heating device of the snow cultivation apparatus is installed in the interior of the cultivation vessel is a heat-efficient cultivation of the surface heating sheet having a high thermal efficiency and excellent waterproofing The installation and maintenance of the heating apparatus for the easy to do, not only to reduce the heating cost, but also to increase the heating efficiency, and to control the internal temperature of the soil, the present invention relates to a snow-cultivation device using a sheet heating sheet. .

The high-altitude cultivation device is a device for cultivating crops at a position higher than the surface of the ground, and is used for growing seedlings of general vegetables or fruits, but is mainly used for cultivating strawberries.

Strawberries grew well at relatively low temperatures and became income crops in winter. However, because the height of the crops is low, all the cultivation work is laid down, so labor intensity is higher than other crops, and the harvesting and growing periods require a lot of labor. Accordingly, the use of the snow-cultivation device that can be cultivated in a comfortable posture by the operator is currently increasing the productivity.

Such a high-altitude cultivation apparatus generally generates heat in order to support a support installed in the ground at a predetermined height, a cultivation container fixed to the support and a predetermined thickness of soil, and to maintain a constant temperature of the soil cultivated in the cultivation container. It consists of a heat generating mechanism, which is disclosed in Korean Patent Laid-Open Publication No. 1999-63345, "Culture Cultivation Equipment", Japanese Unexamined Patent Publication No. 2000-0035431 "Auxiliary equipment for snow cultivation and snow cultivation device".

Here, the high temperature cultivation device is a certain height away from the ground, the heat inside the cultivation vessel can be easily released to the outside as it is exposed to the atmosphere, the soil temperature inside the cultivation vessel in which the crop is growing is below a certain temperature due to the external emission of heat If the temperature is lowered or the soil temperature is not kept constant and irregularly varied, crops cannot grow properly. Therefore, a heat insulating material such as styrofoam is installed in the cultivation container to minimize the release of heat. However, since there is a limit to keep the internal temperature of the soil of the high-altitude cultivation device with only insulation material, the heating device is installed as described above, even if the soil is deprived of heat by supplying heat to the soil of the cultivation container, the soil grows. Maintain the proper temperature continuously.

Conventional snow cultivation apparatus is installed in a plastic house or greenhouse in most cases, the snow cultivation apparatus by heating the atmosphere of the plastic house or greenhouse above a certain temperature by using a heating device generally installed in a plastic house or greenhouse Soil indirectly receives heat from the greenhouse in a greenhouse or greenhouse to maintain a constant temperature. However, in the case of supplying heat to the snow cultivation apparatus using the heating device already installed in the vinyl house or greenhouse, the heating cost is significantly increased as the volume of the vinyl house or greenhouse increases, and the soil is stored in the plastic house. The heating efficiency was low because it was indirectly heated by the atmosphere of the greenhouse.

There is an advanced heating device that has a separate heating device installed in the cultivation container to supply heat directly to the soil inside the cultivation container, but a heating wire with a large power consumption is used as a heating device, or hot water or hot The heating cost was still high and the heating efficiency was not so high as the circulation pipe for temperature control using steam was used. In addition, the heating device made of the heating wire or the temperature control circulation pipe has a complicated configuration, which is cumbersome for installation and maintenance, and inconvenient.

In addition, in order to further promote the growth of high-growing crops, it was necessary to appropriately control the internal temperature of the soil.

Therefore, the present invention improves the problems of the prior art, by using a planar heating sheet as a heating device using a new type of surface heating sheet that can be easily installed and maintained for the heating device for heating of snow cultivation It is an object of the present invention to provide a dredging apparatus.

In particular, it is an object of the present invention to provide a snow-cultivation apparatus using a new type of surface heating sheet that is not only to reduce the heating cost, increase the heating efficiency, but also to easily control the internal temperature of the soil.

According to a feature of the present invention for achieving the above object, the present invention is a support that is placed at a certain height from the ground, a cultivation container fixed to the support and a certain amount of soil is laid, the cultivation container is installed in the temperature of the soil In the conventional chiller cultivation device consisting of a heating device for maintaining a constant, the heating device comprises one or more plane heating sheet in the form of a flat plate of a predetermined length; A temperature sensor installed at a predetermined depth inside the soil; A temperature controller connected to the temperature sensor and the planar heating sheet to control an internal temperature of the soil; It is made into the soil inside the cultivation container is installed in a row or a plurality of rows, the planar heating sheet is a heating layer in which copper wire, polyethylene terephthalate nonwoven layer and conductive carbon black layer is laminated in order, and the heating layer of A linear low density polyethylene film layer, a polyethylene terephthalate nonwoven fabric layer, and a linear low density polyethylene film layer on the upper surface of the upper insulating layer, and a linear low density polyethylene film layer, a polyethylene terephthalate film layer, and a linear layer on the lower surface of the heating layer The low-density polyethylene film layer is made of a lower insulating layer laminated in order to have excellent waterproofness, and the separation between the copper wire and the laminated insulating layer does not occur, it is characterized in that the occurrence of sparks.
