Description

Greenhouse roller shutter device

Technical Field

The invention relates to the technical field of agricultural production, in particular to a roller shutter device of a greenhouse.

Background

The greenhouse, also called as a greenhouse, is transparent and heat-insulating and is a facility for cultivating plants. In seasons unsuitable for plant growth, the method can provide the growth period of the greenhouse and increase the yield, and is mainly used for cultivating or raising seedlings of plants like warm vegetables, flowers and trees in low-temperature seasons. In order to shade sun in the daytime and preserve heat at night, more advanced greenhouses are generally provided with a roller shutter device for covering the greenhouse with a sun-shading net or a heat preservation layer. The existing roller blind device is usually arranged at the top of a greenhouse, covering materials are curled on a roller shaft, and the covering layers are collected and released through the rotation of the roller shaft. The roller shutter device with the structure requires that the covering material has stronger tensile resistance and anti-curling capability, and some light materials with poor strength, good heat-insulating property and low price cannot be applied due to extrusion, scratch and the like, so that the production cost is greatly increased. Meanwhile, due to structural defects, the roller shutter device with the existing structure cannot lay heat-insulating materials with wider amplitude on the same scroll, a plurality of sets of scrolls are used, and joints among heat-insulating layers can influence the heat-insulating effect.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: to the problem, a greenhouse roller shutter device with a more reasonable structure is provided.

The technical solution of the invention is as follows: the utility model provides a big-arch shelter roller shutter device, includes overburden, roller, gyro wheel and rope, and the roller sets up the overburden is in the place of lift in-process, and the roller both ends are passed through the support and are fixed in the periphery of big-arch shelter, and the gyro wheel is used for propping the rope that encloses into the round and restrict the rope along the axial displacement of gyro wheel, and the rope encloses into the round on roller and gyro wheel to form "it" font bending in the south side of big-arch shelter, a plurality of rings of ropes pass through the roller and the gyro wheel encloses in the big-arch shelter periphery, the overburden is outside the big-arch shelter and is fixed on the rope, rotates through driving roller and can drive rope lift overburden.

The invention has the technical effects that: it has the advantages of reasonable structural design, low cost, convenient use, economy and durability. The rope is used as a carrier, the covering layer is pulled to lift through the rope, the middle part of the covering layer is not contacted with other parts, and the problem of scratching is avoided. The covering layer is always outside the rope and cannot be damaged by the rope and the roller shaft. The tension force does not act directly on the cover layer, there is no requirement for the strength of the cover layer, and the cover layer can be lighter and cheaper. The covering layers can be combined into a whole, no seam exists in the middle, and the heat preservation effect is better. The application of the prestressed rope on the roll shaft can ensure that the span length of the roll shaft is longer, reduce the use or not use an intermediate bracket and is more beneficial to the simplification of the structure.

Detailed Description

As shown in fig. 1 and 2, the greenhouse roller blind device comprises a covering layer 1, a roller shaft 2, a roller 3 and a rope 4, wherein the roller shaft 2 is arranged at a position where the covering layer 1 passes through in the lifting process, two ends of the roller shaft 2 are fixed on the periphery of a greenhouse 6 through a support 5, the roller 3 is used for tightly supporting the rope 4 which forms a circle and limiting the displacement of the rope 4 along the axial direction of the roller 3, the rope 4 forms a circle around the roller shaft 2 and the roller 3, the south side of the greenhouse 6 is bent in a zigzag manner, a plurality of circles of ropes 4 are surrounded on the periphery of the greenhouse 6 through the roller shaft 2 and the roller 3, the covering layer 1 is wrapped outside the greenhouse 6 and fixed on the rope 4, and the rope 4 can be driven to lift the covering layer 1 through the rotation of the driving roller shaft 2.

The greenhouse 6 is provided with underground pipe holes 7 penetrating through the south and north sides of the greenhouse 6 on the ground, rollers 3 are arranged at two ends of each underground pipe hole 7, and the ropes 4 penetrate through the underground pipe holes 7 and are wound on the roller shafts 2 and the rollers 3.

The roll shaft 2 is composed of a prestressed cable 8, a shaft tube 9 and a bearing 10, two ends of the prestressed cable 8 are respectively fixed on the supports 5, the shaft tube 9 is sleeved on the prestressed cable 8, the bearing 10 is arranged at the end part of the shaft tube 9, the bearing 10 in contact with the supports 5 adopts a thrust bearing, and the shaft tube 9 is tightly clamped between the two supports 5 through tensioning of the prestressed cable 8.

The shaft tube 9 is multi-segmented.

The length of the common greenhouse is longer, and the middle of the roller shaft can be provided with a bracket for preventing the roller shaft from collapsing. The L-shaped bracket can be added into the overlapped part of the zigzag shape from the gap which is not contacted with the covering layer, so that the L-shaped bracket is not directly contacted with the covering layer. The prestressed cable is adopted as the shaft core, so that a middle bracket can be reduced or not used, the structure is greatly simplified, and the production cost is reduced. The bottom of the covering layer can be added with some strengthening structures such as net shape which is connected with the ropes surrounding the greenhouse. The heat-insulating greenhouse is generally transparent on the south surface and the top surface, the heat-insulating masonry is arranged on the north surface, and the covering layer only needs to cover the south surface and the top surface of the greenhouse. When not in use, the covering layer is pulled to the part, which is arranged on the north side of the greenhouse and is overlapped with the rope in the shape of the Chinese character 'ji', of the greenhouse through the rope for storage. The underground pipe hole can be preset on the foundation part, and a pipe which is not easy to rust can be adopted. The roller blind can be driven by manpower or electricity, wherein the contact surface of the roller shaft positioned at the lowest part and the rope is large, and a driving wheel can be added on the pipe to be used as a driving shaft. It is also possible to provide the drive shaft separately and to drive it by providing it with a drive wheel which is wound over a large area with rope.
