Description

TECHNICAL FIELD

[0001] The utility model relates to a greenhouse technical field, especially relate to a greenhouse heat preservation quilt folding device. BACKGROUND

[0002] The existing arched shed or arc-shaped shed adopts an external heat preservation form, the heat preservation quilt thereof adopts a bottom-up winding mode, the heat preservation quilt is wound on the winding shaft and is driven by the winding motor to be wound along the roof of the greenhouse. During the day, the greenhouse needs to be lighted, and the heat preservation quilt is wound up and placed at the position of the roof ridge of the greenhouse, and at night, the heat preservation quilt is unwound.

[0003] In the existing external heat preservation form, the heat preservation quilt is exposed to the outside, and after rain and snow enter, the heat preservation quilt is easily wetted, which affects the heat preservation performance of the heat preservation quilt. The heat preservation quilt is wound on the winding shaft and unwound, and during the winding process, the winding motor and the winding shaft move along the roof in an arc together. Since the winding motor is very heavy, the winding shaft near the winding motor becomes heavier and heavier, so that the tension received by the heat preservation quilt is different, which causes the winding shaft to be not straight, the heat preservation quilt is easily deviated, and faults are prone to occur. Since the heat preservation quilt is not wound straight, in actual production, the final parking position of the wound heat preservation quilt is often away from the top of the roof ridge by a distance to prevent the heat preservation quilt from being wound too much, but this increases the shadow shielding of the heat preservation quilt on the crops in the shed, and when the heat preservation quilt is wound along the roof of the greenhouse, the rolling of the heat preservation quilt generates concentrated stress on the framework, which is easy to damage the clamping groove, and the direct contact of the heat preservation quilt with the covering material of the greenhouse also generates a certain friction on the covering material, which reduces the light transmittance and service life of the covering material.

[0004] The internal heat preservation form of the existing greenhouse shed adopts a curtain pulling structure. A light and thin heat preservation quilt is located between the curtain supporting line and the curtain pressing line and is folded or unfolded by the driving edge. The existing greenhouse curtain pulling structure is divided into a gear and rack curtain pulling system and a steel cable curtain pulling system according to the transmission mode, but the wound heat preservation quilt of the curtain pulling structure is irregularly stacked between the curtain supporting line and the curtain pressing line, and after being wound, the area is large and the light shielding is serious, which is not conducive to the growth of some light-loving crops.

[0005] The internal heat preservation form of the existing greenhouse shed also adopts a winding heat preservation structure, but is unfolded downward and wound upward by gravity, and needs an additional supporting framework, the application scene is very limited, the additional supporting framework is high in cost and serious in shading, and is not conducive to the growth of plants; the plant hanging line is usually installed in the existing greenhouse shed, and the top space of the hanging line is narrow and cannot stack the heat preservation quilt.
