Abstract
Description
Technical Field
[0001] This application relates to the technical field of vegetable cultivation, specifically a ventilation device for vegetable greenhouses. Background Technology
[0002] Vegetable cultivation is an agricultural activity involving multiple stages. From seed selection to final harvest, each step has a significant impact on the growth and yield of vegetables. When planting crops, workers usually use greenhouses to grow vegetables, and the ventilation performance of the greenhouse is very important. When carrying out ventilation, ventilation devices are often used.
[0003] A search revealed that patent CN220493756U discloses a ventilation device for vegetable greenhouses. This device uses a motor to drive an adjusting block to rotate, which in turn moves an adjusting rod up and down. The first connecting block connected to the adjusting rod then drives the second connecting rod up and down, and the moving block rotates the louvers. This solves the problem that existing ventilation devices cannot be shut off when ventilation is not needed. It also prevents external pests and rainwater from entering the interior. A solar panel is installed at the top of the outer shell to provide solar power, thus improving the energy efficiency of the device.
[0004] However, during long-term use of the ventilation device, the outer casing cannot be quickly removed and the louvers replaced, which affects the ventilation performance inside the greenhouse. In view of this, we propose a ventilation device for vegetable greenhouses. Utility Model Content

When the ventilation fan 32 is damaged after long-term use, the push rod 35 can be manually pushed so that the push rod 35 enters the connecting plate 33 along the damping spring 34, so that the staff can remove the connecting plate 33 from the air box 30. After disassembly, the ventilation fan 32 can be quickly removed from the mounting base 31 for replacement.
[0035] Reference Figure 2 and Figure 4 In one aspect of this embodiment, two fixing members 2 are provided, and the two fixing members 2 are respectively installed at both ends of the bellows 30. The fixing member 2 includes a moving groove 20, and a moving rod 21 is fixedly installed inside the moving groove 20. A plurality of fixing cones 22 for fixing effect are slidably connected to the surface of the moving rod 21.
