[0039] See also Figures 1 to 4As shown, the embodiment of the present application provides an automatic sunshade system for horticultural crop cultivation, including a shading mechanism and a driving device 2. The shading mechanism includes a sunshade frame 1 and multiple sunshade mechanisms 3. The sunshade frame 1 includes multiple beams 11, and each of the beams 11 is arranged in parallel and at intervals; each beam 11 corresponds to a sunshade mechanism 3, and the sunshade mechanism 3 includes a sunshade curtain 31, a winding device 32 and a linkage mechanism. Each of the winding devices 32 is connected to the linkage mechanism, and one end of each sunshade curtain 31 is connected to a corresponding beam 11 and the other end is connected to a corresponding winding device 32. The driving device 2 is connected to the beam 11. The driving device 2 can drive the winding device 32 to reciprocate in a direction perpendicular to the beam 11 through the linkage mechanism. The sunshade curtain 31 can be wound on the winding device 32 or extended out of the winding device 32.

[0040] The automatic sunshade system for horticultural crop cultivation of the patent application, when in use, the driving device 2 moves in one direction to drive the winding device 32 to move away from the beam 11 connected to the sunshade mechanism 3, and then under the pull of the winding device 32, the sunshade curtain 31 is extended from the winding device 32 and unfolded between adjacent beams 11, thereby increasing the shielding area to shield the sunlight. If the shielding is to be released, the driving device 2 is operated to drive the winding device 32 to move in the direction of the beam 11 connected to the sunshade mechanism 3, and the sunshade curtain 31 is wound on the winding device 32, thereby reducing the shielding area and increasing the sunlight exposure.

[0041] In a possible implementation, the driving device 2 includes a motor 21 and a gear 22, and the linkage mechanism includes a transmission gear rod 13. The motor 21 is connected to the beam 11, the gear 22 is transmission-connected to the output end of the motor 21, the transmission gear rod 13 is transmission-connected to the gear 22, and the winding device 32 is arranged on the transmission gear rod 13.

The support roller can not only provide support force for the transmission gear rod 13, but also because the design of the roller changes the sliding friction into rolling friction, the friction force is smaller and the required pulling force is smaller, which protects both the equipment and the motor 21.

[0045] In a possible implementation, each of the transmission gear rods 13 includes a sawtooth segment 131 and two connecting rod segments 132, and the sawtooth segment 131 is transmission-connected to the gear 22. The length of the sawtooth segment 131 is equal to the spacing between the beams 11, and the two connecting rod segments 132 are respectively arranged at both ends of the sawtooth segment 131, and the connecting rod is supported on the support roller. The sawtooth segment 131 is used to connect with the gear 22, and drives the entire transmission gear rod 13 to move through transmission. The connecting rod segment 132 is not provided with sawtooth, has a relatively smooth surface, and has a small contact friction with the support roller, so it is not easy to be damaged.

The sawtooth segment 131 is provided above the gear 22 to ensure the stability of the transmission connection through its own weight, so that the drive shaft 14 and the gear 22 will bear a large weight, and the support seat is provided to ensure that the drive shaft 14 and the gear 22 can bear such a large weight.

[0048] In a possible embodiment, two groups of shielding mechanisms are included, and the two groups of shielding mechanisms are arranged on the upper and lower sides of the driving device 2.

The driving shaft 14 is provided with a circle of passive gear ring at the position passing through the gear support seat 9. The output shaft of the motor 21 is connected to the passive gear ring through the gear 22. The driving shaft 14 is driven to rotate clockwise or counterclockwise by controlling the rotation direction of the motor 21. The two groups of gears 22 can rotate with the driving shaft 14, and then drive the transmission gear rod 13 to reciprocate. There are two groups of driving devices 2, which are arranged in parallel up and down. Each group of driving devices 2 has two groups of gears 22 and two transmission gear rods 13, and share the same motor 21 and driving shaft 14. Due to the different positions of the gears 22, the transmission directions of the transmission gear rods 13 of the two groups of driving devices 2 are opposite. At the same time, the sunshade curtain 31 is switched to a state of shielding sunlight or a state of not shielding sunlight. The setting of the double-layer sunshade curtain 31 can ensure that the light received by the plant canopy is more uniform in the three modes of double-layer, single-layer and no sunshade.

[0049] Furthermore, a bearing is provided between the gear support seat 9 and the driving shaft 24 to reduce friction.

The columns 12 support the cross beam 11 to provide space for planting crops below, and the connecting beam 13 connects adjacent columns 12 to provide support force, so that the structure of the entire sunshade frame 1 is more stable.

The environmental monitoring sensor 7 can monitor the environmental conditions of the planting area in real time, such as temperature, light intensity, rain intensity, wind force, etc. The monitored environmental conditions are then sent to the intelligent control box 8, which determines and calculates the area that should be shaded by the sunshade curtain 31 according to the environmental conditions, and then the intelligent control box 8 controls the driving device 2 to shade or release the shade according to the calculation results.

[0053] In a possible implementation, the winding device 32 includes a central axis, a coil spring and a shell, and a curtain outlet is arranged on the shell along the length direction of the shell.
