[0002] In order to achieve temperature control and allow plants to grow better, agriculture upgrades greenhouses to multi-span greenhouses (multi-span greenhouses). Multi-span greenhouses have the advantages of better control of the environment, low heating costs, high land utilization, sufficient internal space, easy expansion, flexible zoning, and a high degree of automation. However, ventilation and rain and snow removal in multi-span greenhouses are difficult, and the temperature inside the greenhouse is low at night in winter. In order to ensure the temperature inside the multi-span greenhouse at night, thermal insulation blankets are usually laid on the multi-span greenhouse, and thermal insulation blankets are also added to the top and north and south sides of the greenhouse. The setting of the inner and outer double-layer thermal insulation blankets can effectively isolate the greenhouse from the outside cold air layer and ensure the temperature inside the greenhouse.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0019] like Figure 1 、 Figure 2 As shown, this embodiment provides a simple quilt driving structure suitable for a multi-span greenhouse, including a front drive assembly and a rear drive assembly installed on each arch frame 1 of the multi-span greenhouse; the front drive assembly has the same structure as the rear drive assembly, and is respectively arranged at the front and rear ends (i.e., the north and south ends) of the arch frame 1, and both include a screw quilt winding motor 2, a first fixed pulley 3, a second fixed pulley 4, a quilt rope 5, and a steel wire 6; wherein the screw quilt winding motor 2 is arranged near the top of the arch frame 1 and can be installed and fixed on the arch frame 1 through a connecting bracket (not shown); the first fixed pulley 3 and the second fixed pulley 4 are respectively arranged on the left and right sides (i.e., the east and west sides) of the arch frame 1, and the quilt rope 5 is wound around the transmission shaft of the screw quilt winding motor 3 (also called a winding bar, the size of the winding bar in this embodiment is φ48mm*3.0), one end passes around the first fixed pulley 3, and the other end passes around the second fixed pulley 4, and then the two ends are connected and the quilt rope 5 is in a taut state, forming a closed loop and the quilt rope 5 in a taut state is fixedly connected to the movable end of the unfolded thermal insulation quilt 7;

[0020] The steel wire 6 (φ8mm) is arranged horizontally along the arch frame 1 and is in a taut state; the other end of the thermal insulation quilt 7 is fixed in the shed (the specific fixing method is not limited in this embodiment, and those skilled in the art can use any existing method to fix it), and a plurality of quilt slots 8 are arranged at intervals along the longitudinal direction of the arch frame 1 at the bottom of the thermal insulation quilt 7. Hooks 9 are provided at both ends of the quilt slots 8. The hooks 9 pass through the quilt slots 8 and the thermal insulation quilt 7, and the upper ends are connected to the pulley 10; the pulley 10 at the front end of the thermal insulation quilt 7 is arranged on the steel wire 6 of the front drive assembly, and the pulley 10 at the rear end of the thermal insulation quilt 7 is arranged on the steel wire 6 of the rear drive assembly. The steel wires 6 at the front and rear ends are equivalent to the tracks of the pulley 10, and the pulley 10 always moves along the steel wire 6, thereby driving the thermal insulation quilt 7 to move.

[0021] In this embodiment, the quilt pocket slot 8 is fixedly connected to the thermal insulation quilt 7, and the hook 9 is installed on the pulley 10 by hanging.

[0022] It should be noted that in this embodiment, the quilt pocket slot 8 can directly adopt the film slot commonly used in existing greenhouses. Of course, other slots can also be used. In this embodiment, the quilt pocket slot 8 is mainly used to hold the thermal insulation quilt 7, so that the thermal insulation quilt can be folded or unfolded at the quilt pocket slot 8 when automatically controlling it.

[0023] Further, if Figure 2 As shown, in this embodiment, a gasket 11 is provided on the hook 9, and the gasket 11 is arranged on the top of the thermal insulation quilt 7. The thermal insulation quilt 7 is clamped and fixed on the hook 9 through the gasket 11 and the quilt slot 8.

[0024] The quilt driving structure provided in this embodiment is such that the thermal quilt 7 is in the unfolded state, and the length of the quilt rope 5 wound on the first fixed pulley 3 is shorter than the length of the quilt rope 5 wound on the second fixed pulley 4. When the driving screw winding motor 2 is used to retract the thermal quilt, the length of the quilt rope 5 wound on the second fixed pulley 4 is continuously shortened under the action of the transmission shaft, pulling the thermal quilt 7 and causing the pulley 10 to slide to the right along the steel wire 6. At this time, the length of the quilt rope 5 wound on the first fixed pulley 3 is continuously lengthened, compensating for the displacement difference, so that the thermal quilt can be unfolded or retracted at will under the action of the quilt rope 5.

[0025] In addition, in order to completely isolate the roof of the multi-span greenhouse from the interior of the greenhouse, when the thermal insulation blanket 7 is in the unfolded state, the end portion of the movable end of the thermal insulation blanket 7 can be manually fixed in the greenhouse so that there is no gap between the thermal insulation blanket and the roof, further ensuring the temperature in the greenhouse.

[0026] The above are specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
