The invention provides a wind-releasing device and a wind-releasing component, and relates to the technical field of plant breeding devices. The wind-releasing device comprises a wind-shielding cloth,a support frame, a cloth-rolling rod and a rotating mechanism. The wind-shielding cloth is connected on the support frame, and the lower end of the wind-shielding cloth can be rolled up along the support frame to ventilate the greenhouse; the cloth-rolling rod is connected at the lower end of the wind-shielding cloth, and the cloth-rolling rod can roll the wind-shielding cloth upwards along the lower end of the wind-shielding cloth; one end of the rotating mechanism is connected on the support frame, and the other end of the rotating mechanism is connected to the cloth-rolling rod; when the rotating mechanism is running, the cloth-rolling rod can be driven to rotate, and the wind-shielding cloth is intertwined around the cloth-rolling rod. The technical problems in the prior art are solved, for example, the plastic film is lapped on the side of the greenhouse and the fixing mode of the greenhouse is insecure, and the plastic film is easy to tear in windy weather. The wind-shielding cloth is connected on the support frame through the rotating mechanism, and the cloth-rolling rod is driven to curl the wind-shielding cloth by the running of the rotating mechanism, so that the purposeof ventilation in the greenhouse is achieved.
Description
technical field [0001] The invention relates to the technical field of plant cultivation devices, in particular to an air release device and an air release assembly. Background technique [0002] The vegetable greenhouse is a frame-covered structure with thermal insulation performance. Using the vegetable greenhouse to plant vegetables, people can eat vegetables that are out of season. The vegetable greenhouse mainly adopts the framework of bamboo structure or steel structure, which is covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. [0003] In the above-mentioned prior art, during the growth of seeds in the vegetable greenhouse, most of the dry weight of the plant comes from photosynthetic products. During the day, in the greenhouse, due to the photosynthesis of veg...
