Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

The melon and vegetable greenhouse ventilation device shown in fig. 1, 2 and 3 comprises a greenhouse body, wherein the greenhouse body comprises a supporting framework 1 and a plastic film 2 sleeved outside the supporting framework 1, a slide rail 3 is fixedly mounted outside the plastic film 2, a ventilation opening 4 is formed in the slide rail 3, a ventilation mechanism 5 for adjusting the ventilation size is mounted in the ventilation opening 4, namely the ventilation mechanism 5 is limited by the slide rail 3, so that the ventilation mechanism 5 is more stable during adjustment, the ventilation size is convenient to adjust, specifically, the ventilation mechanism 5 comprises a threaded rod 6 and a wind-blocking film 10, the threaded rod 6 is arranged outside the plastic film 2, a bearing seat rotatably connected with the threaded rod 6 is sleeved outside the threaded rod 6, the bearing seat penetrates through the plastic film 2 and is connected with the supporting framework 1, namely the threaded rod 6 can rotate in the vertical direction outside the plastic film 2, the threaded rod 6 is externally sleeved with a first connecting rod 7 and a second connecting rod 8 which are in threaded connection with the threaded rod, the second connecting rod 8 is connected with the first connecting rod 7 through two sliders 9, the two sliders 9 are fixedly connected through a wind shielding film 10, the sliders 9 are arranged on the sliding rails 3 and are in sliding connection with the sliding rails, when the sliders 9 are matched with the sliding rails 3, the wind shielding film 10 is tightly attached to the plastic film 2, preferably, the area of the wind shielding film 10 is larger than that of the ventilation openings 4, so that the sealing performance during non-discharging can be ensured, when discharging is needed, the threaded rod 6 is rotated, due to the matching of the sliding rails 3 and the sliders 9, the first connecting rod 7 and the second connecting rod 8 synchronously ascend or descend under the rotation of the threaded rod 6, the wind shielding film 10 and the wind discharging openings 4 are staggered, the stable adjustment of the size of discharging is realized, and only the threaded rod 6 needs to be rotated, convenient operation, when letting out wind mouth 4 and set up when a plurality ofly moreover, can realize adjusting a plurality of sizes of letting out wind mouth 4 simultaneously, adjust efficiently.
