An automatic rolling shutter device for agricultural greenhouses

Abstract

The invention discloses an automatic roller blind device for agricultural greenhouses, which relates to the technical field of agricultural equipment, and mainly solves the problem that when laying straw curtains on agricultural greenhouses, because the straw curtains are relatively soft, the two ends of the curtains are laid unevenly during laying. There is a large gap, which affects the heat preservation of the agricultural greenhouse. This device mainly includes the agricultural greenhouse body. One side of the agricultural greenhouse body is equipped with a limit mechanism, a rainproof mechanism, an indicating mechanism, a controller, an automatic roller shutter mechanism, and a gap covering The mechanism drives the rotating shaft to rotate through the deceleration motor, and stretches the roller blind shaft to move through the transmission belt, which is convenient for laying and rolling up the covering straw. When the roller blind shaft moves, the roller blind shaft can be oriented through the arc slide , to ensure the flatness of both sides of the covering grass curtain, and the supplementary grass curtain on the rotating shaft can also be pulled to move, and it is laid between the gaps covering the grass curtain. The beneficial effect of the invention is that the laid straw curtains are smoother, more comprehensively laid, and have better thermal insulation effect.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an automatic rolling shutter device for agricultural greenhouses. Background technique [0002] In order to ensure the temperature in the agricultural greenhouse in winter, it is necessary to lay straw curtains outside the agricultural greenhouse. Because the straw curtain itself is heavy, the area of ​​the agricultural greenhouse is also relatively large. Manual laying will not only waste a lot of manpower and material resources, but also reduce work efficiency. relatively low. [0003] In the prior art, for example, the patent number is CN201821118598.4, and the patent name is a patent for a blueberry cultivation greenhouse automatic rolling machine device, which mainly uses the cooperation of the first servo motor, screw, screw and moving block to utilize the screw The rotation drives the moving block to move, thereby driving the second belt pulley to move, whi...
