As shown in fig. 1 and fig. 2, the present embodiment provides a greenhouse top heat preservation structure, which includes a heat preservation quilt 100, a rolling rod 200, a sliding rail 300 and a driving mechanism 400, wherein the sliding rail 300 is disposed on the top of the greenhouse, the rolling rod 200 is erected on the sliding rail 300, one end of the heat preservation quilt 100 is fixed on the rolling rod 200, and the other end is fixed on the top of the greenhouse. Drive mechanism 400 includes a drive 403, a drive member 401, a driven wheel 402, and an engagement track 404; the driver 403 is in transmission connection with the winding rod 200 through the transmission member 401 and the driven wheel 402, and is used for driving the winding rod 200 to rotate bidirectionally. Driven wheel 402 may be drivingly connected to winding bar 200 via a keyway structure.

The engagement rail 404 is fixedly disposed and perpendicular to the winding bar 200. The driven wheel 402 is also meshed with the meshing track 404, so that when the driver 403 drives the driven wheel 402 to rotate through the transmission part 401, the driven wheel 402 simultaneously rolls along the meshing track 404, and the rolling rod 200 is driven to store and release the heat preservation quilt 100. When the rolling rod 200 rotates along the rolling direction, the heat preservation quilt 100 can be rolled onto the rolling rod 200, and the other end of the heat preservation quilt 100 is fixed on the top of the greenhouse, so that the heat preservation quilt 100 can pull the rolling rod 200 simultaneously when the rolling rod 200 rolls the heat preservation quilt 100, the rolling rod 200 with the heat preservation quilt 100 can move freely, and the heat preservation quilt 100 can be rolled to be smaller by the pulling force of the heat preservation quilt 100. When the winding bar 200 rotates in the unwinding direction, since the driven wheel 402 is engaged with the engaging rail 404, the driven wheel 402 drives the winding bar 200 to rotate and move along the length direction of the engaging rail 404 at the same time, thereby smoothly unwinding the quilt 100.

In this embodiment, the cross member 600 is disposed at a position near the top of the greenhouse or the top of the greenhouse, so that the slide rail 300 can be disposed at a position near the top of the greenhouse.

Of course, the sliding rails 300 and the engaging rails 404 can be disposed on the structural members of the greenhouse top, or can be directly disposed on the vertical posts 500, and can be selectively disposed as required. The plurality of beams 600 may be arranged side by side at intervals, a plurality of continuous grid spaces are formed on the top of the multi-span greenhouse, the spaces are used as areas to be insulated and covered by the heat-insulating structure 100, the heat-insulating structure is fixed in the spaces, and the grid spaces are covered after the heat-insulating structure 100 is unfolded. The setting of results such as stand 500 and crossbeam 600 of this embodiment not only makes insulation construction's installation and connection become easier, and the planning and the design of the greenhouse early stage of being convenient for, avoids the extravagant or the low condition of efficiency of construction of material in later stage, the overall cost of reducible greenhouse.

Example three. On the basis of the above embodiment, the driver 403 of the present embodiment is a motor. In order to drive winding rod 200 to rotate and move on sliding rail 300 or engaging rail 404, driving mechanism 400 includes a driving member 401 and driven wheels 402, wherein driven wheels 402 are disposed at two ends of winding rod 200 and are in driving connection with driving member 401. As the driven wheel 402 rotates, the winding rod 200 rotates. Two ends of the winding rod 200 are respectively connected with a driven wheel 402 with the same specification, and when the two driven wheels are in transmission connection with respective transmission members 401, the winding rod has a more stable operation effect.

However, as a modification of the present embodiment, the driving member 401 may be provided only on the driven wheel 402 at one end, and the driven wheel 402 at the other end may be engaged only with the engagement rail 404. It is also possible to provide a driven wheel 402, a transmission member 401 and an engaging rail 404 only at the middle position of the winding bar 200, and the driven wheel 402 and the engaging rail 404 should be provided with a larger width to ensure the lateral attitude of the winding bar 200.
