DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 , the utility model provides a technical solution:

[0025] A film rolling device, comprising

[0026] The top frame 1 is made of metal and is arranged on the top of the entire greenhouse;

[0027] The support frames 2 are symmetrically welded on both sides of the top frame 1, and the support frames 2 are equidistantly arranged along the length direction of the top frame 1, thereby forming the frame structure of the entire greenhouse with the top frame 1. In the technical solution of this embodiment, the support frames 2 are arc structures, and a total of five groups of support frames 2 on each side are provided, and the specific number can be set according to the actual length of the greenhouse;

[0028] The winding roller 4 is arranged on the support frames 2 on both sides and has the functions of rotation and movement. The winding roller 4 rotates on itself and moves along the support frames 2 to realize the retraction and release of the greenhouse film 7; first driving wheels 5 are arranged at both ends of the winding roller 4, and the first driving wheels 5 adopt a gear structure. The first driving wheel 5 is meshed with the racks 3 on the support frames 2 at the front and rear ends. When the winding roller 4 moves along the support frames 2 under the action of the driving device, the winding roller 4 has a self-rotation movement under the action of the rack 3; blocks 6 for limiting the position of the greenhouse film 7 are arranged at both ends of the winding roller 4. By setting the blocks 6, the greenhouse film 7 is not easy to deviate during the winding process; a slider is arranged at the lower part of the block 6, and the slider is slidably connected to the support frame 2. By setting the slider, the winding roller 4 can move closely along the support frame 2, thereby ensuring that the first driving wheel 5 can mesh smoothly with the rack 3;

[0029] A greenhouse film 7 is wound on a winding roller 4, and one end of the greenhouse film 7 is fixedly connected to the top frame 1;

[0030] The motor 8 is fixedly arranged at one end of the top frame 1, and a brake is integrated on the motor 8. The brake is used to brake the motor 8 so that the rollers 4 on both sides can stop at any position on the support frame 2 (for mold opening and ventilation) to avoid automatic falling; the main shaft of the motor 8 is connected to the power input end of the reducer 9, and the power output end of the reducer 9 is connected to the drive shaft 15. The reducer 9 is rotatably provided with an input shaft 10 and an output shaft 11. The input shaft 10 and the output shaft 11 are respectively connected to the main shaft of the motor 8 and the drive shaft 15. The input shaft 10 and the output shaft 11 are respectively provided with a second drive wheel 12 and a third drive wheel 13. The second drive wheel 12 and the third drive wheel 13 are connected through a drive belt 14. A plurality of drive shafts 15 are arranged along the length direction of the top frame 1 through a bracket 16, and adjacent drive shafts 15 are axially connected through a coupling 17. Each drive shaft 15 is provided with a first reel 18 and a second reel 19, and

[0031] The belt 20 is wound around the first reel 18 and the second reel 19, and the other end of the belt 20 is connected to the top frame 1 after passing around the reel 4. Since the belt 20 is wound around the reel 4, when the reel 4 is winding the greenhouse film 7, the belt 20 can exert pressure on the greenhouse film 7, thereby achieving that the greenhouse film 7 can be tightly wound on the reel 4;

[0032] It can be seen from the above structural description that: by arranging multiple groups of drive shafts 15 on the top frame 1, and the adjacent drive shafts 15 are connected by couplings 17, the length of the entire drive shaft 15 can be greatly extended, and it can be suitable for agricultural greenhouses with longer lengths; at the same time, two reels are arranged on each group of drive shafts 15, and the two reels can respectively drive the rollers 4 on both sides to move under the action of the winding belt 20, so that one group of driving devices can be used to retract and release the greenhouse films 7 on both sides, avoiding the need to adapt two groups of driving devices, and greatly reducing the application cost;

[0033] The utility model also provides an agricultural greenhouse, comprising the above-mentioned film rolling device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
