Description

Technical Field

[0001] The utility model relates to the field of off-season vegetable greenhouses, and in particular to an off-season vegetable planting greenhouse. Background Art

[0002] Vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It allows people to eat off-season vegetables. Generally, vegetable greenhouses use bamboo or steel structure frames, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growth of vegetables inside, making the greenhouse have a good thermal insulation effect.

[0003] Most of the existing vegetable planting greenhouses use manual laying of plastic sheets, which is inefficient. In case of strong winds and rain, the plastic film in the greenhouse needs to be quickly recovered, but the manual operation is slow. Some vegetable greenhouses in the prior art can also perform plastic film rolling operations, but the subsequent plastic film laying operations still require manual operation, and the plastic film will have wrinkles during the rolling process, which the existing technology cannot effectively solve. After a long period of rolling operation, such wrinkles will cause the strength of the plastic film at that location to become low.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The reduction motor is installed on the outer side of the side mounting plate at the front end, and the output end of the reduction motor is connected to the front end center of the plastic sheet taking-up and releasing roller on the same side. The transmission gear has two parts respectively rotatably installed on the outer side of the side mounting plate at the rear end and are respectively connected to the two transmission cable taking-up and releasing shafts on the same side.

[0008] As a preferred technical solution of the present utility model, the two transmission gears are of the same model and mesh with each other.

[0009] As a preferred technical solution of the utility model, two plastic sheet perforations are arranged inside the longitudinal positioning beam, and the internal dimensions of the two plastic sheet perforations are adapted to the width of the plastic sheet.

[0026] In this embodiment, the off-season vegetable planting greenhouse is used as a planting unit, and the length can be freely assembled according to needs.

[0027] Among them, the operation of splicing multiple units can adapt to the covering operation of different planting environments, and each greenhouse is independent of each other and as a whole. The greenhouse in that position can be selected according to the needs for recycling or lowering operations.

[0028] In this embodiment, the two transmission gears 45 are of the same model and mesh with each other.

[0029] The design of the transmission gear 45 can ensure that the plastic sheets 2 on both sides use the same driving source, thereby ensuring that the plastic sheets 2 on both sides are rolled up or lowered at the same speed.

[0030] In this embodiment, two plastic sheet through-holes 9 are arranged inside the longitudinal positioning beam 3 , and the inner dimensions of the two plastic sheet through-holes 9 are adapted to the width of the plastic sheet 2 .

[0031] In this embodiment, the part of the transmission cable 7 away from the plastic sheet retracting and releasing mechanism 4 slides and fits on the lower rail surface of the guide rail 5, and the other end of the transmission cable 7 passes through the inner side of the bottom end of the arched side bracket 1 and docks with the inside of the plastic sheet retracting and releasing mechanism 4.

[0032] In this embodiment, the plastic sheet taking-up and releasing mechanism 4 includes a side mounting plate 41, a plastic sheet taking-up and releasing roller 42, a transmission cable taking-up and releasing shaft 43, a reduction motor 44 and a transmission gear 45. The side mounting plate 41 has two front and rear ends installed at the bottom of the longitudinal positioning beam 3. The plastic sheet taking-up and releasing roller 42 is symmetrically arranged between the front and rear ends of the side mounting plates 41. The transmission cable taking-up and releasing shaft 43 has four parts respectively connected to the two ends of the two plastic sheet taking-up and releasing rollers 42. The transmission cable taking-up and releasing shaft 43 is rotatably connected to the side mounting plate 41 on the same side. The reduction motor 44 is installed on the outer side of the side mounting plate 41 at the front end. The output end of the reduction motor 44 is connected to the front end center of the plastic sheet taking-up and releasing roller 42 on the same side. The transmission gear 45 has two parts respectively rotatably installed on the outer side of the side mounting plate 41 at the rear end and are respectively connected to the two transmission cable taking-up and releasing shafts 43 on the same side.

[0033] Among them, the reduction motor 44 inside the plastic sheet retracting and unwinding mechanism 4 is started, thereby driving the plastic sheet retracting and unwinding rollers 42 on both sides and the transmission cable retracting and unwinding shafts 43 at both ends to rotate synchronously, thereby unscrewing the plastic sheet and simultaneously performing a winding operation on the transmission cables 7 on both sides. During the winding process, the transmission cables 7 on both sides pull the docking slide bar 6 to slide downward inside the guide rails 5 on both sides, thereby allowing the released plastic sheet 2 to be pulled out from the plastic sheet perforations 9, and finally fully unfolded to cover the entire outer side of the arched side bracket 1 to form a protection. When the plastic sheet 2 is no longer needed, it is only necessary to reversely start the plastic sheet retracting and unwinding mechanism 4, and drive the plastic sheet retracting and unwinding rollers 42 and the transmission cable retracting and unwinding shafts 43 at both ends to rotate synchronously in the opposite direction through the reduction motor 44, thereby performing a winding operation on the plastic sheet and simultaneously performing a releasing operation on the transmission cables 7 on both sides until the docking slide bar 6 slides to the top of the guide rails 5 on both sides.

[0035] The design of multiple guide wheels 8 can ensure that the transmission cable 7 can be closer to the top, thereby avoiding interference between the transmission cable 7 and people walking inside.

[0036] In specific applications, select the appropriate number of greenhouses for assembly according to actual planting needs.

[0037] After assembly is completed, the reduction motor 44 inside the plastic sheet retracting and unwinding mechanism 4 can be started, thereby driving the plastic sheet retracting and unwinding rollers 42 on both sides and the transmission cable retracting and unwinding shafts 43 at both ends to rotate synchronously, thereby unscrewing the plastic sheet and simultaneously reeling the transmission cables 7 on both sides. During the reeling process, the transmission cables 7 on both sides pull the docking slide bar 6 to slide downward inside the guide rails 5 on both sides, thereby the released plastic sheet 2 can be pulled out from the inside of the plastic sheet perforations 9, and finally fully unfolded to cover the outside of the entire arch side bracket 1 to form protection. When the plastic sheet 2 is no longer needed, it is only necessary to start the plastic sheet retracting and unwinding mechanism 4 in the reverse direction, and drive the plastic sheet retracting and unwinding rollers 42 and the transmission cable retracting and unwinding shafts 43 at both ends to rotate synchronously in the reverse direction through the reduction motor 44, thereby reeling the plastic sheet and simultaneously releasing the transmission cables 7 on both sides until the docking slide bar 6 slides to the top of the guide rails 5 on both sides.
