Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural planting, and in particular relates to a sunshade net for a greenhouse. Background Art

[0002] At present, agricultural greenhouses are used more and more widely in agricultural planting. Since the surface of the agricultural greenhouse is only covered with a layer of plastic film, although it can play a good role in heat preservation, it cannot block the sunlight, especially in the hot summer. Due to the strong ultraviolet rays, it is easy to cause damage to the crops in the greenhouse. In order to solve the problem of strong light exposure, people mostly use sunshade nets to cover the surface of the greenhouse film to block the strong light. However, the existing sunshade nets are mainly covered on the surface of the greenhouse manually, which is not only difficult to operate, but also the covered sunshade nets are not easy to retract, so that the amount of sunlight received by the greenhouse cannot be adjusted.

[0003] To this end, a sunshade net for agricultural greenhouses with a bulletin number of "CN216532899U" includes a greenhouse body, a winding mechanism and a support frame, a traction plate is symmetrically arranged between the two support frames, one side of the traction plate is fixedly connected to the sunshade net, both ends of the traction plate are fixedly connected to sliders, and one side of the support frame is provided with a slideway that slides with the slider; a column is fixed to the inner side of the support frame, a groove connected to the slideway is opened in the column, a driving motor is fixed in the groove, a screw is fixed to the output shaft of the driving motor, a lifting block that slides with the screw thread is slidably connected in the groove, and a traction rope is symmetrically fixed on the top of the lifting block, and the other ends of the two traction ropes are fixedly connected to adjacent sliders respectively. It is not only convenient to cover the sunshade net on the surface of the greenhouse, but also the area of ​​the greenhouse covered by the sunshade net can be adjusted, thereby adjusting the amount of sunlight received by the greenhouse.

[0004] However, for the above-mentioned sunshade net for agricultural greenhouses, although the support frames are respectively arranged at the two ends of the greenhouse body and fixedly connected to each other, and the winding mechanism is fixedly installed between the two support frames and respectively arranged on both sides of the greenhouse body, there are still the following obvious defects during use: the support frames arranged at both ends of the greenhouse body are installed and fixed as an integrated structure. When the support frames are installed, they are not designed as a combined structure and cannot be quickly installed on the greenhouse body by manual labor. The installation of the support frames must be completed by lifting equipment, which will cause the support frames to scratch and damage the film covering the greenhouse and the main frame during the lifting process.
