Description

Technical Field

[0001] The utility model relates to the technical field of cultivation and planting, in particular to a multi-span rain shelter for cultivation. Background Art

[0002] The multi-span rain shelter is a commonly used facility in agricultural production, especially for fruit tree planting. It can reduce disease infection, improve fruit setting rate, and improve fruit quality. The reasons for using a multi-span rain shelter in cultivation are to control environmental factors, improve economic benefits, and expand the planting range, etc.

[0003] Reducing disease infection is mainly reflected in that the multi-span rain shelter can effectively prevent rainwater from directly attacking the leaves and fruits of fruit trees such as grapes, significantly reducing the incidence of diseases caused by a humid environment.

[0004] For different crop varieties, the rain shelter will adopt a partial or full rain sheltering method. Among them, the partial method mainly shelters rain through the ceiling on the top of the rain shelter, and usually no shielding objects are set around the rain shelter. While the full rain shelter will use a film to enclose the whole rain shelter to achieve a full rain sheltering effect, while ensuring light transmittance. Both methods require separate construction of the rain shelter, resulting in the possible need to demolish the original rain shelter when dealing with different crops. Therefore, a multi-span rain shelter for cultivation is proposed, which can replace the partial or full rain sheltering method without completely demolishing the original rain shelter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1

[0037] A multi-span rain shelter for cultivation, including an installation frame 1. A plurality of arc-shaped brackets 2 are evenly fixed at the upper end of the installation frame 1. A ceiling 4 is arranged outside the arc-shaped brackets 2, and the arc-shaped brackets 2 can further support the ceiling 4. Moreover, a connecting rod 21 is fixed between the plurality of arc-shaped brackets 2 to improve the support stability of the arc-shaped brackets 2.

[0038] At both sides of the upper end of the installation frame 1, clamping grooves are respectively opened. At the same time, at both sides of the lower end of the ceiling 4, docking plates 41 are respectively fixed. The ceiling 4 is clamped with the clamping grooves of the support sleeves 32 through the docking plates 41 to assemble the ceiling 4 and the installation frame 1. A positioning frame is slidably connected inside the installation frame 1, and the docking plates 41 can be fixed through the positioning frame to keep the ceiling 4 and the installation frame 1 stable after assembly.

[0039] Specifically, the positioning frame includes a sliding plate 7 and a plurality of inserting plates 71. The sliding plate 7 is slidably connected inside the installation frame 1. The plurality of inserting plates 71 are arranged at equal intervals at one end of the sliding plate 7 close to the docking plate 41. Moreover, a plurality of inserting holes are opened inside the docking plate 41, and the number of inserting holes is the same as the number of inserting plates 71. After the sliding plate 7 slides, the inserting plates 71 can be inserted into the inserting holes of the docking plate 41 to complete the fixation between the ceiling 4 and the installation frame 1.

[0040] Furthermore, installation boxes 8 are respectively arranged at both inner ends of the installation frame 1. Three rotating rods 81 are rotatably connected inside the installation boxes 8. There is a distance between the three rotating rods 81 and they do not contact each other. Moreover, the three rotating rods 81 are all threadedly connected with the inside of the sliding plate 7. When the rotating rods 81 rotate, the whole positioning frame can be driven to slide. A round rod 84 is rotatably connected at one end of the installation box 8 away from the installation frame 1, and the round rod 84 is fixed to one rotating rod 81. Among them, tooth rings 82 are fixed at the outer ends of the three rotating rods 81. A transmission belt 83 is arranged outside the three tooth rings 82. Moreover, a plurality of tooth blocks are evenly arranged inside the transmission belt 83. The transmission belt 83 is meshed with the three tooth rings 82 through the tooth blocks arranged on its inner side. When the round rod 84 is rotated to drive one rotating rod 81 to rotate, the transmission belt 83 can transmit the rotation of the tooth rings 82, so that the three rotating rods 81 rotate simultaneously, and then the whole positioning frame slides.

[0041] When using the ceiling 4 for rain and sun shading, first place the ceiling 4 at the outer end of the arc-shaped bracket 2. After the docking plate 41 is clamped with the card slot of the mounting frame 1, rotate the round rod 84. Under the driving action of the transmission belt 83 on the toothed ring 82, the three rotating rods 81 rotate simultaneously, so that the sliding plate 7 drives the positioning frame to slide as a whole towards the side close to the docking plate 41. When the insertion plate 71 is inserted into the insertion hole of the docking plate 41, the installation of the ceiling 4 and the mounting frame 1 is completed. At this time, rain and sun shading can be carried out through the ceiling 4.

[0042] Embodiment 2

[0043] Based on Embodiment 1, when it is necessary to use a film for sun shading and heat preservation, first reverse the round rod 84. Under the driving action of the transmission belt 83 on the toothed ring 82, the three rotating rods 81 rotate simultaneously. At this time, the positioning frame slides as a whole towards the side away from the docking plate 41. When the insertion plate 71 completely disengages from the inside of the slot of the docking plate 41, the ceiling 4 can be removed from the mounting frame 1. Then, lay the film on the outer surface of the arc-shaped bracket 2, and straighten the edges of the film to both sides so that the film fits as closely as possible to the outer surface of the arc-shaped bracket 2. Subsequently, put a part of the film into the card slot of the mounting frame 1. At this time, rotate the round rod 84. After the positioning frame is reset, the insertion plate 71 can press the film tightly in the card slot of the mounting frame 1, maintaining the stretched state when the film fits as closely as possible to the outer surface of the arc-shaped bracket 2, making the outer surface of the film flat and reducing the accumulation of rainwater.

[0044] Embodiment 3

[0045] Based on Embodiment 1, a number of support sleeve rods 3 are respectively arranged on both sides of the lower end of the mounting frame 1. The support sleeve rods 3 play a role in supporting the whole rain shelter. The support sleeve rods 3 are set as a telescopic structure, so that while supporting the rain shelter, the height can also be adjusted. A bottom plate 5 is fixed at the bottom of the support sleeve rod 3, and a number of insertion rods 51 penetrate through the inside of the bottom plate 5. By inserting the insertion rods 51 penetrating through the bottom plate 5 into the ground, the whole rain shelter can be installed at the required position.

[0046] Specifically, the support sleeve rod 3 includes a support column 31 and a support sleeve 32. The support column 31 is fixed at the upper end of the bottom plate 5, and the support sleeve 32 is slidably connected to the inside of the support column 31, and one end of the support sleeve 32 is fixed to the mounting frame 1. By the sliding of the support sleeve 32 inside the support column 31, the whole support sleeve rod 3 is set as a telescopic structure, so as to adjust the height position of the mounting frame 1 and the arc-shaped bracket 2. And a plug pin 6 is arranged at the connection between the support column 31 and the support sleeve 32 to fix the position of the support sleeve 32 after sliding.

[0047] Further, a number of docking grooves 321 are equidistantly formed on each of the opposite surfaces of every two symmetric support sleeves 32, and insertion holes are formed on each of the opposite surfaces of every two symmetric support columns 31. A latch pin 6 is slidably connected in each insertion hole. After the support sleeve 32 is slid to the required height, the docking groove 321 is aligned with the insertion hole on the corresponding support column 31, and then the latch pin 6 is respectively engaged with the docking groove 321 and the insertion hole on the support column 31 to complete the fixation of the support sleeve 32 after the adjustment of its position.
