Embodiment Construction

[0011] Below in conjunction with accompanying drawing, describe the present invention in detail:

[0012] Technical solution: A greenhouse insulation curtain retractable device, including a counterweight 1, a roller 2, a cable 3 and a positioning mechanism 4, the two rollers are set on the roof of the greenhouse 7, and the counterweight 2 and the insulation curtain 6 pass through the cable 3 Connected, the cable 3 is hung on the roller 2, and the positioning mechanism 4 is arranged on the outer side of the vertical wall of the greenhouse.

[0013] Generally, the greenhouse is a half-slope structure, that is, the sunny side is a slope, and the other side is a vertical wall. In the present invention, the roller 2 is arranged on the top of the ridge of the greenhouse 7, that is, directly above the vertical wall, and the counterweight 1 is hung on the outside of the vertical wall. Be relaxed and comfortable. When putting down the thermal insulation curtain 6, open the positionin...

Abstract

The invention discloses a greenhouse thermal insulation curtain rolling and unrolling device, and belongs to the field of agricultural production equipment. The greenhouse thermal insulation curtain rolling and unrolling device is used for rolling and unrolling a greenhouse thermal insulation curtain. The greenhouse thermal insulation curtain rolling and unrolling device comprises a counterweight (1), a roller (2), a cable (3) and a locating mechanism (4). The roller (2) is placed at the top of a ridge of a greenhouse (7), the counterweight (1) is connected with the thermal insulation curtain (6) through the cable (3), the cable (3) is hung on the roller (2) and the locating mechanism (4) is arranged on the outer side face of a perpendicular wall of the greenhouse (7). The greenhouse thermal insulation curtain rolling and unrolling device is very convenient to use, and rolling and unrolling of the thermal insulation curtain can be controlled easily at constant speed; in addition, a brick or wood which is common in rural areas can be used as the counterweight, no much investment is needed and the investment is low.

Description

technical field [0001] The invention relates to a retractable device, in particular to a retractable device for thermal insulation curtains in greenhouses, belonging to the field of agricultural production equipment. Background technique [0002] The food basket is related to thousands of households, and a little carelessness will affect the living standards of citizens. Behind the continuous impact of new words such as "garlic you ruthless", "jiang you army" and "sugar Gaozong" are the residents' helplessness and self-deprecation in the face of rising prices.
