Symmetrical down-folding type greenhouse internal thermal insulation device

Abstract

The invention relates to a symmetrical down-folding type greenhouse internal thermal insulation device. The device comprises a greenhouse body, a speed reduction motor, and thermal insulation quilts,wherein the speed reduction motor is connected to a driving synchronous pulley; the driving synchronous pulley is separately connected to a driven main synchronous pulley and a driven secondary synchronous pulley on a main belt pulley shaft and a secondary belt pulley shaft through a double cogged synchronous belt; the main belt pulley shaft and the secondary belt pulley shaft drive guiding grooved pulleys of a guiding wheel axle I and a guiding wheel axle II; the other ends of steel wire ropes on the two sides bypass the bottoms of the guiding grooved pulleys of the guiding wheel axle I and the guiding wheel axle II respectively and are fixedly connected to quilt drive hoisting devices arranged on the thermal insulation quilts on the two sides of a greenhouse respectively; the thermal insulation quilts on the two sides are pulled and spread out. According to the symmetrical down-folding type greenhouse internal thermal insulation device, grooved pulley sets are fixed to the thermal insulation quilts, and slide along guide rails; a button controls the speed reduction motor to rotate during work; a power shaft pulls the thermal insulation quilts for spreading through a drive mechanism to achieve a greenhouse internal thermal insulation function; a whole working process is efficient and simple, and is convenient for people to operate.

Description

technical field [0001] The invention relates to the technical field of greenhouses, in particular to a symmetrical downward folding type greenhouse inner heat preservation device. Background technique [0002] Greenhouses are widely used in my country's facility horticulture industry, which can provide plants with the necessary temperature and light in an environment that is not suitable for plant growth. Due to the coldness in the northern region, in order to increase the temperature in the greenhouse, it is usually necessary to add heat preservation measures to the greenhouse. At present, agricultural solar greenhouses usually focus on external insulation, and the insulation layer is covered outside the greenhouse film. However, this insulation method has poor insulation effect and is inconvenient to store and store. Moreover, once it is soaked by rain and snow, it will not only increase the thermal insulation quilt. The weight will also reduce the insulation performance....

AI Technical Summary

Problems solved by technology

However, most of the technical solutions adopted by the existing internal thermal insulation devices are to set up scaffolding again in the greenhouse. The internal thermal insulation method continues to use the external thermal insulation device, and the thermal insulation is laid from top to bottom. The operation traction is large and it is not easy for people to operate. Bloated and expensive
