A roll-up device for a sunshade net on the outer wall of a glass greenhouse

Abstract

The invention relates to a greenhouse technology, in particular to a winding device for a sunshade net of a glass greenhouse external wall. The winding device comprises a drive shaft, winding pipes and winding ropes. The drive shaft is a through shaft which is formed by connecting a large-diameter drive shaft (1) with a small-diameter drive shaft (2), and the sunshade net is divided into a long net and a short net. The bottom end of the long net is wound around the long net winding pipe, and the bottom end of the short net is wound around the short net winding pipe above an obstacle. The winding pipe wound around the large-diameter drive shaft is wound around the long net winding pipe (8) so that the long net winding pipe (8) can be lifted, and the winding pipe wound around the small-diameter drive shaft is wound around the short net winding pipe (8') so that the short net winding pipe (8') can be lifted. The winding device has the advantages that the mode that two sets of drive devices are adopted for the long net and the short net in the prior art is changed into the mode that the diameter-variable drive through shaft is arranged; only one set of drive device is adopted for unified control, the large-diameter through shaft and the small-diameter through shaft of the diameter-variable through drive shaft are arranged, and although the lengths of the wound nets are different at a period, the long net winding pipe and the short net winding pipe can wind and lift the nets to top points at the same time; the mechanism arrangement is simplified, equipment and investment are saved, the occupied space is reduced, and operation and control are easy.

Description

[0001] Technical field: [0002] The invention relates to greenhouse technology, in particular to a roll-up device for a glass outer wall greenhouse sunshade net. [0003] Background technique: [0004] Greenhouses with hollow glass exterior walls need to be equipped with sunshade nets rolled out at regular intervals outside the exterior walls to control indoor light and temperature changes. The defect of the prior art is that when there is an obstacle on the outer wall of the greenhouse, such as a gate opened on the wall, in order to leave a gate, the sunshade net at this time is divided into two parts, and the upper part corresponding to the gate is a short net, and the rest is a short net. It is a long net that can be placed on the ground. When the net is rolled, the length of the net is different and the distance traveled is different. Therefore, the driving shaft for winding the rope cannot be a through shaft, but can only be set in sections. A set of drive shafts and dri...

Problems solved by technology

The defect of the prior art is that when there is an obstacle on the outer wall of the greenhouse, such as a gate opened on the wall, in order to leave a gate, the sunshade net at this time is divided into two parts, and the upper part corresponding to the gate is a short net, and the rest is a short net. It is a long net that can be placed on the ground. When the net is rolled, the length of the net is different and the distance traveled is different. Therefore, the driving shaft for winding the rope cannot be a through shaft, but can only be set in sections. A set of drive shafts and drive devices is specially set up, and a set of drive shafts and drive devices are respectively set on the rest of the two sides of the door, which increases equipment and investment, takes up more space, and is cumbersome to control
