Description

Technical Field

[0001] The utility model relates to the technical field of vegetable greenhouses, in particular to an automatic film rolling mechanism for high-mountain vegetable planting greenhouses. Background Art

[0002] During the process of high-mountain vegetable planting, greenhouses are needed for heat preservation in low-temperature periods, and at the same time to prevent sun exposure, rain, etc., and can also play a heat preservation role at night. At present, vegetable greenhouses generally adopt a steel frame structure, covered with plastic film or other light-transmitting materials on the outside.

[0003] After retrieval, a Chinese patent discloses a vegetable planting greenhouse (authorized announcement number CN218499686U), which includes a base frame assembly, end films, side films, a top film and a winding assembly. End films are provided at both ends of the base frame assembly, side films are provided at the lower parts on both sides of the base frame assembly, a top film is provided at the upper end of the base frame assembly, winding drums are connected to the lower ends of the side films and the top film, winding assemblies are connected to both ends of the winding drums, limit frames are provided at both ends of the base frame assembly near the winding assemblies, the base frame assembly is composed of an end face support frame, a cross tie rod and a middle support frame, and the winding assembly is composed of a sliding sleeve, a first adjusting rod, a second adjusting rod, a first locking bolt, a second locking bolt, an adjusting groove and an installation groove. Although this patented technology can be assembled according to the needs of vegetable planting, and during later replacement, local single-piece replacement can be carried out to reduce the disassembly and assembly area without affecting planting.

Two fixed strips 3 are fixedly connected between the first greenhouse side plate 1 and the second greenhouse side plate 2. A long screw 4 is rotatably connected inside one of the fixed strips 3. A U-shaped inner groove is opened inside the first greenhouse side plate 1. A U-shaped frame 8 is arranged inside the U-shaped inner groove. A plastic film 9 is fixedly connected between the U-shaped frame 8 and the inner wall of the U-shaped inner groove. The outer side of the long screw 4 is threadedly connected with the U-shaped frame 8. A watering mechanism is arranged between the first greenhouse side plate 1 and the second greenhouse side plate 2. An automatic closing mechanism is arranged inside the first greenhouse side plate 1. A stabilizing mechanism is arranged inside the fixed strip 3.

[0030] During use, by rotating the long screw 4, the U-shaped frame 8 can be driven to slide inside the fixed strip 3, and then the plastic film 9 inside the U-shaped inner groove can be gradually pulled out, so that the grower can quickly roll up and unfold the plastic film 9, and then can provide protection for vegetables and other crops before the sudden weather comes, avoiding the death of the crops, improving the productivity, and also saving a lot of manpower and material resources.

[0031] Referring to Figure 2 , the stabilizing mechanism includes a fixed rod 7 fixedly connected inside the other fixed strip 3. The U-shaped frame 8 is slidably connected with the fixed rod 7. The bottom ends of the U-shaped frame 8 are both slidably connected with the inner wall of the fixed strip 3.

[0032] During use, through the arrangement of the fixed rod 7, the U-shaped frame 8 can be made more stable during the winding process, so that the winding structure can operate stably.

[0033] Reference Figure 3 As shown in Figure 3 , the automatic closing mechanism includes an opening 17 formed inside the first greenhouse side plate 1. An installation groove is formed inside the first greenhouse side plate 1 and above the opening 17. A winding roller 13 is rotatably connected inside the installation groove. A curtain 15 is wound around the outer side of the winding roller 13. A counterweight 16 is fixedly connected to the bottom end of the curtain 15. A controller 18 is fixedly installed on the outer side of the first greenhouse side plate 1.

[0034] When a grower enters the vegetable planting greenhouse, the controller 18 can be used to control the operation of the winding roller 13. By rotating the winding roller 13, the curtain 15 wound around its outer side can be slowly lowered. When the grower comes out from the inside, the second servo motor 12 can be controlled to reverse. Also, when ventilation is required for vegetables and other crops, the opening 17 can be opened according to the above operation.

[0041] Working principle: First, the controller 18 controls the first servo motor 10 to start. Through the rotation of the long screw rod 4, the U-shaped frame 8 can be driven to slide in the fixed strip 3. And through the setting of the fixed rod 7, the U-shaped frame 8 can be more stable during the winding process, enabling the winding structure to operate stably. Furthermore, the plastic film 9 in the U-shaped inner groove can be gradually pulled out, so that the grower can quickly wind and unwind the plastic film 9. Thus, before the sudden weather comes, it can provide protection for vegetables and other crops, avoid the death of crops, improve productivity, and also save a lot of manpower and material resources.

[0042] And the outside water pump supplies water to the water pipe 5, and through the nozzle 6, the vegetables are watered. Moreover, the setting of the water pipe 5 can also provide a certain supporting force for the unfolded plastic film 9. When the grower enters the vegetable planting greenhouse, the controller 18 can be used to control the winding roller 13 to operate. Through the rotation of the winding roller 13, the curtain 15 wound around its outer side can be slowly lowered. When the grower comes out from the inside, the second servo motor 12 can be controlled to reverse. And when ventilation is needed for vegetables and other crops, the opening 17 can also be opened according to the above operations for the grower to use.
