[0025] As Figure 2 、 Figure 3 and Figure 4As shown in the figure, the sunshade assembly 24 includes a winding and unwinding roller 241 rotatably installed in the inner cavity of the greenhouse main body 10. A sunshade cloth 242 is wound around the surface of the winding and unwinding roller 241. One side of the sunshade cloth 242 away from the winding and unwinding roller 241 sequentially penetrates through the box body 21 and a housing 15 and extends between the two brackets 22. A fixing rod 243 is fixedly installed on one side of the sunshade cloth 242 between the two brackets 22. A connecting rod 244 is installed through the inside of the fixing rod 243. Transmission gears 245 are sleeved on both sides of the surface of the connecting rod 244. The transmission gears 245 are meshed and connected with the toothed plate 23; A first motor 246 is arranged on one side of the bracket 22. The output end of the first motor 246 penetrates through the bracket 22 and is connected with one of the transmission gears 245;

[0026] In this embodiment, when the first motor 246 works, it drives the transmission gear 245 and the connecting rod 244 to rotate synchronously. While the transmission gear 245 is rotating, the fixing rod 243 automatically pulls the sunshade cloth 242 through the meshing of the toothed plate 23 and the transmission gear 245, covering and shading the top of the greenhouse main body 10;

[0027] In this embodiment, a driven bevel gear 247 is fixedly installed on the surface of one end of the winding and unwinding roller 241.

The top of the support roller 2404 is in contact with the bottom of the sunshade cloth 242; It can support the sunshade cloth 242 when it moves, avoiding the situation that the sunshade cloth 242 rubs against the housing 15 when it moves, resulting in damage to the sunshade cloth 242;

[0030] Strip-shaped holes 2405 are formed at the tops on both sides of the housing 15. One side of the sunshade cloth 242 away from the winding and unwinding roller 241 penetrates through the strip-shaped holes 2405 and extends between the two brackets 22. One-way bearings are installed between the driven bevel gear 247 and the winding and unwinding roller 241 and between the connecting rod 244 and the transmission gear 245, and the one-way bearings are installed on both sides of the surface of the connecting rod 244.

[0031] When the utility model shades the main body 10 of the greenhouse, the first motor 246 works to drive the transmission gear 245 and the connecting rod 244 to rotate synchronously. While the transmission gear 245 is rotating, the fixed rod 243 automatically pulls the sunshade cloth 242 through the engagement between the toothed plate 23 and the transmission gear 245 to cover and shade the top of the main body 10 of the greenhouse. When the sunlight is weak, the staff turns on the second motor 248 to work. The second motor 248 drives the winding and unwinding roller 241 to turn through the meshing connection between the driving bevel gear 249 and the driven bevel gear 247, and the sunshade cloth 242 can be wound up.
