Greenhouse rolling device

Abstract

The invention provides a greenhouse rolling device and relates to a rolling device for a greenhouse. The invention aims to provide the greenhouse rolling device which has the advantages of simple structure and convenience in use, and can prevent curtain rolling ropes from being wound in a disorder manner. The greenhouse rolling device provided by the invention comprises a rope rolling shaft (1), a plurality of curtain rolling ropes (2) wound on the rope rolling shaft, and a curtain (3), and further comprises a plurality of rope guide devices (4), wherein each rope guide device comprises a shaft sleeve (5) with a step hole; a rope guide cylinder (6) is arranged on the outer lateral wall of each shaft sleeve; a digging rope (9) is arranged on each rope guide cylinder; the other end of the digging rope is fixed below the rope guide cylinder; each curtain rolling rope and each digging rope are connected by using a 8-shaped pendant (10); a cylindrical rolling pendant (12) is further arranged and can be rolled or unrolled together with the curtain under the effect of the curtain rolling ropes; and a sunshade, rainproof and snow-proof cover (17) is arranged above the rope rolling shaft.

Description

technical field [0001] The invention relates to a rolling screen device, in particular to a rolling screen device for a greenhouse. Background technique [0002] The existing greenhouse roller blind device usually uses a motor to drive the input shaft of the reducer, and the output shaft of the reducer then drags the rolling shaft installed on the frame to rotate. The cords move synchronously to draw up or spread out the curtains used to cover the greenhouse. In the process of retracting or spreading the curtain, due to various reasons, the length of the curtain cord is often deviated, causing the cord to be broken by the cord during the process of retracting or spreading, or the cord cannot be stretched. Spread out evenly. For this reason, people sometimes use their hands to directly adjust the curtain-retracting rope that is wound into a ball on the roller blind shaft. People's fingers, sleeves, clothes corners, hair, palms, etc. are twisted on the equipment, causing se...

Problems solved by technology

In the process of retracting or spreading the curtain, due to various reasons, the length of the curtain cord is often deviated, causing the cord to be broken by the cord during the process of retracting or spreading, or the cord cannot be stretched. spread out evenly

For this reason, people sometimes use their hands to directly adjust the curtain-retracting rope that is wound into a ball on the roller blind shaft. Twist people's fingers, sleeves, clothes corners, hair, palms, etc. on the equipment, causing serious casualties, and causing pain and great economic losses to the parties and their families

In addition, when it is necessary to lay anti-rain and snow plastic sheets on the surface of the greenhouse in rainy and snowy weather, due to the inconsistent degree of tightness of the curtain ropes, it is necessary to adjust the position of the curtain ropes, which also increases the labor intensity of the relevant personnel.

During the use of the existing greenhouse roller blind device, when the curtain cloth is rolled out and completely rolled out, due to the light weight of the curtain cloth, it is easy to be blown up by the wind and cannot play the role of greenhouse insulation.

Furthermore, when the curtain is spreading downward, due to the light weight of the curtain, it is easy to get stuck halfway and cannot be rolled out smoothly.
