Abstract

This design is related to Utility Model Registration No. 089160 (Registered on July 29, 1995, Practical New Generation Author, Hwang Woo Sung), 'Greenhouse Insulating Fabric'.

Heat Seed Seedlings Facility Seedlings are digging in the seedlings and burying the heat line. It is a ground heating method that arranges the heating line on the heat cover which must be covered in the middle of the day. It is planted in December ~ March, so it digs the ground to maintain the temperature. There is a lot of manpower consumed and frequent disconnection, which leads to lost money.

The felt or nonwoven fabric which is currently used as a thermal insulation cover has problems such as moisture absorption, ventilation, dust generation, and too heavy, so it is used as a thermal insulation cover by covering the thermal insulation with a cotton film. (2) and (4) in Fig. 3 are obtained by using a chemical cotton (cacheiron) or a vegetal cotton pad as a cotton pad and covering the paper pad [Fig. 2] (1) and (5) to control the temperature of the connection of the coated heating wire of (3) to the temperature controller of the arrangement (7) between the cotton of (2) and (4) ) Is an agricultural film. Put the cotton inside which the heating wire is embedded in the film made by both sides of the barrel, fold the both ends (6), and finish with the compression device such as the fixing device and the high frequency adhesive machine.

On the inner side, fix the film with a compression device such as a fixing device (6) at appropriate intervals to prevent the flow of the heating wire and prevent the film from fluttering.

This design reduces the manpower to dig up the soil, and the conventional formula has a large heat loss due to heat generation in the underground part, and it evaporates the moisture in the seedbed soil, Is a simultaneous heating system with a coating, and forms a warm temperature film, and at the same time, the inside heat is confined, and the inside is dried, and the heat is raised to the upper heat as in nature.

Description

Electrical warming cover {.

Korea's agriculture is cultivated in cold winter from December to March, and it grows in spring with lots of sunshine time in 3 ~ 5 month, and it needs to harvest more before the rainy season to improve quality and quantity. do.

Conventionally, in order to cultivate in the cold winter, dig the ground and put leaves and rice straw. Rice straw was transferred to the inside of 20cm and the moisture content was 70 ~ 80%, and the seedlings were planted in which the soil was heated and covered with the soil. After that, the styrofoam was used instead of the heat-generating material and the styrofoam box was raised in parallel with the seedling growing.

At present, the thermal grave facility is to dig the ground and flatten it so that it can arrange the heating line, then lay the trees on both sides of the grave and make a uniform heat flow by arranging narrow lines on both sides and spreading the soil and soil. It takes a lot of manpower because of the detailed work. In addition, the heating wire frequently breaks during wiring, during seedling seeding, and during seeding, and fails to recover the sown seeds when the seedling is broken. And you can not use it again.

The thermal insulation cover in our country uses a felt or covers several layers of nonwoven fabric, but it has a problem of high heat conductivity due to moisture absorption, low heat insulation through cold air, dust generation, and moisture absorption.

[Configuration and Effect of Design]

[Fig. 3] The cotton of (2) and (4) is controlled by using a light cotton pad and (3) arranging the heating wire and connecting it to the temperature controller.

Based on the heating line, the cotton is thinned inward to cover the top surface to induce heat generation, and the outer part is thickened to increase the thermal insulation.

Use a film made from both sides of the outer surface, put the cotton with the heating wire in it, fold it at both ends (6) press the tape with a compression device like a fixing device or attach it with high frequency to maintain the temperature inside It forms a temperature film and it is wrapped in film to remove the moisture that is generated, so that the thermal insulation is increased.

In order to prevent the flow of the heating wire arranged inside the insulating cover and to prevent the film from fluttering, it is fixed with a compression button such as a fixing device.

As shown in [Fig. 2], when the seedling is coated, there is no inconvenience of arranging the heating wire in the ground, and the heating action is performed simultaneously with the coating.

(7), it keeps the proper temperature at night even at a low temperature of 13 ~ 15 ℃ and keeps the heat inside it warm.

If hot wire is placed in the ground, it is often necessary to dispose of the seedlings in the arrangement, seedling of the seedlings or to break the line when recovering the line in the soil. With this design, the heating wire is arranged in the cotton so that the impact is less and safe. In addition, although the seedling was heated up under the ground until now, it was heated underground, so that the wetness was excessively generated, and the seedlings were softly grown due to the excessive humidification. However, since the heat insulating cover covering the upper part was heated, As well as suitable for plant physiology and nursery is grown.
