technical field

The utility model relates to the technical field of thermal insulation for vegetable greenhouses, in particular to a built-in folding covering device for a solar greenhouse.

Background technique

In cold regions, existing solar greenhouses are still covered with grass curtains and tarpaulins for insulation. The disadvantage is that manual operation is cumbersome, labor-intensive, and time-consuming; during mechanical operation, due to the heavy load, long wheelbase, and easy breakage of the shaft, it may also be out of sync during operation, causing the insulation layer to be laid down or wound; especially in In rainy and snowy weather, these conditions are more serious due to the dampness of straw curtains and tarpaulins.

When in use, the retraction and release of the thermal insulation sheet is controlled by the control mechanism. When recycling, first disconnect the thermal insulation sheet from the vertical curtain, then retract the thermal insulation sheet, and hang it on the load-bearing steel wire rope or slide rail in a folded shape; when retracting, first fold the thermal insulation sheet near the high-end part, and then fold the low-end part, No damage to crops on the low end.

The utility model has the advantages of:

1. The utility model is easy to operate, which can solve the labor-intensive and time-consuming problems of retracting and unwinding the tarpaulin, and reduce labor intensity.

2. The air layer between the built-in tarpaulin of the present invention and the light-transmitting layer of the greenhouse plays the role of isolation and heat preservation, which can more effectively keep plants warm.

3. The utility model has a built-in tarpaulin, which avoids damage to the tarpaulin caused by sunlight, rain and snow, and prolongs the service life.

4. It is convenient to improve the air quality in the greenhouse. Long-term airtight insulation in the greenhouse in winter will reduce the air quality in the greenhouse. When the sun is sufficient during the day, use the tarpaulin to cover the crops, open the ventilation window to exchange the air between the tarpaulin and the light-transmitting layer with the fresh air from the outside, and then close the ventilation window to use sunlight to heat the air between the tarpaulin and the light-transmitting layer Air, and then open the tarpaulin; the crops are not in direct contact with the cold air when ventilating in the greenhouse, which protects the normal growth of the crops and the health of the workers.
