Description

Technical Field

[0001] This utility model belongs to the field of agricultural facility technology, specifically, it relates to a multi-span shading greenhouse. Background Technology

[0002] Traditional greenhouses mostly use a single-span structure, which has problems such as low space utilization and inconvenient adjustment of the shading system.

[0003] Utility model CN212813143U discloses a rapidly assembleable multi-span greenhouse, including a first column and a second column symmetrically positioned to the right of the first column. The top of the first column is bolted to the bottom of a first connecting member, and the top of the second column is bolted to the bottom of a second connecting member. A crossbeam is bolted between the first and second connecting members. Arched rods with an arc structure are connected to the upper inner sides of both the first and second connecting members via assembly tubes. In this utility model, the various components of the greenhouse are installed and disassembled via connecting members and assembly members, facilitating operation and reducing worker workload. The assembly members include connecting plates and adjusting plates, with a sunshade cloth between them. The connecting plates can be extended and retracted via a drive wheel, and the connecting plates also drive multiple adjusting plates for easy extension and retraction.

[0004] However, the aforementioned patents still have the following problems: their shading devices are usually fixed or manually adjustable. Although the manual adjustment mode is an improvement over the manual operation of traditional single-span greenhouses, it still suffers from low efficiency in unfolding / retracting the shading net. When a rapid adjustment of the shading state is required, manual operation cannot meet the timeliness requirements, especially in the face of sudden weather changes, making it difficult to react quickly and inconvenient to use.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0029] Working principle: The retractable structure includes a first retractable section and a second retractable section. In the first retractable section, the top of the support column 10 has a first fixed plate 16, and the tops of the two sets of second fixed plates 28 have sliding grooves 36. The slider 35 slides in the sliding grooves 36 and is connected to a moving plate 34 at the top. One side of the moving plate 34 is connected to one side of the first fixed plate 16. In the second retractable section, the top of the second fixed plate 28 has a third fixed plate 29 and a fourth fixed plate 30. One side of the third fixed plate 29 is equipped with a servo motor 31, and the other side is connected to a threaded rod 32. The output shaft of the servo motor 31 is connected to one end of the threaded rod 32 through a coupling. One side of the fourth fixed plate 30 is connected to a rotating rod 33. One end of the threaded rod 32 is fixed to one end of the fourth fixed plate 30. The moving plate 34 is connected to a threaded sleeve 37, and the threaded rod 32 is inside the threaded sleeve 37. The servo motor 31 is started to drive the threaded rod 32 to rotate, causing the threaded sleeve 37 to rotate on the outer wall of the threaded rod 32. This drives the moving plate 34 to move, causing the slider 35 to slide in the slide groove 36, which in turn drives the first fixed plate 16 to move, thereby realizing the raising and lowering of the sunshade cloth. There are two sets of first positioning plates 17 on one side of the outer wall of the first fixed plate 16, with first limiting holes 18 inside, and limiting bolts 19 installed in the holes. There are four sets of first sunshade cloths 25 at the top of the canopy column 10, and one set of first waterproof cloth 20 is connected to each end (a total of eight sets). Two sets of second positioning plates 21 are fixed inside the first waterproof cloth 20, with second limiting holes 22 inside. The second positioning plates 21 are snapped between the two sets of first positioning plates 17, and the limiting bolts 19 are inserted through the first limiting holes 18 and the second limiting holes 22, limiting the second positioning plates 21 within the two sets of first positioning plates 17. The first sunshade cloths 25 are fixed by the two sets of first waterproof cloths 20, and the first sunshade cloths 25 are raised and lowered by moving the first fixed plate 16. The top of the four sets of first waterproof cloth 20 is fixed with two sets of rubber rods 23, and the top of the rubber rods 23 is fixed with rubber caps 24. The rubber caps 24 are fixed by the rubber rods 23. The top of the other four sets of first waterproof cloth 20 is fixed with second sunshade cloth 26, and two sets of third limiting holes 27 are opened at the top. Rubber rods 23 are sleeved in the third limiting holes 27. The second sunshade cloth 26 is sleeved between the two sets of rubber covers 24. A set of first connecting plates 11 and a set of second connecting plates 12 are fixed to the outer wall of the canopy column 10. A first fixing rod 13 is fixed between each set of first connecting plates 11 and second connecting plates 12. A set of second fixing rods 14 and a set of arc-shaped fixing rods 15 are fixed between every two sets of second connecting plates 12 (a total of six sets of second fixing rods 14 and six sets of arc-shaped fixing rods 15). The first and second connecting plates are fixed through the canopy column 10, and then the first and second fixing rods and arc-shaped fixing rods 15 are fixed by them. The second waterproof cloth 38 is pasted on one side of the outer wall of the second fixing plate 28. The bottom is tightly attached to the top of the movable plate 34. A plastic cloth 39 is placed between the two sets of second waterproof cloths 38. The second waterproof cloth 38 covers the side of the canopy frame, and the plastic cloth 39 covers the top of the canopy frame.
