Abstract

The invention belongs to crop greenhouse production equipment, and in particular relates to a heat insulating device of a nitrogen charged air bag of a crop greenhouse. A mat covered on the top of a plastic crop greenhouse in the prior art, so that the defects of easiness to damage, short service life and high cost exist in the prior art. The outer surface of an outer layer (3) of the device provided by the invention is provided with a protective layer (1), an inner layer (9) is internally provided with air bags (4), and the inner layers of the air bags (4) are provided with air bag inner layer protective layers (10); a communicating pipe (5) is arranged between every two adjacent air bags (4); the upper part of the outer layer (3) is provided with an air bag charging pipe (2); the upper side, the left side and the right side of the outer layer (3) are provided with fixing rings (7); and the lower part of the outer layer (3) is provided with a bottom edge (6). The heat insulating device has the advantages of low cost, capability of saving time for rolling or unrolling the mat every day, rapidness in temperature rise and good heat insulation effect in winter, reduction of light saturation points, and light weakening, and is suitable for crop growth in summer, good in wind resistance and suitable for windy places.

Description

technical field [0001] The invention belongs to production equipment for crop greenhouses, in particular to a nitrogen-filled air bag heat preservation device for crop greenhouses. Background technique [0002] In order to improve the efficiency of agricultural production and enable the smooth growth of crops in cold seasons in high latitudes, protected cultivation of crops has been widely promoted, and plastic greenhouses are widely used. In the prior art, in order to maintain the temperature in the greenhouse, straw curtains are covered on the top of the plastic greenhouse for crops, covered at night, and rolled up when the temperature is high during the day. The disadvantages of the prior art are: the rewinding of the straw curtains is easy to cause damage, the service life of the straw curtains is short; the cost of agricultural production is high; and it is troublesome to use at the same time. Due to the increase in the cultivation area of ​​protected areas year by yea...
