Two mounting plates 11 are fixedly installed on the inner wall of one side of the power bin 2 close to the greenhouse main body 1, and a flattening component is arranged between the two mounting plates 11 to prevent the sunshade cloth 5 from being wrinkled when rolled up.

[0028] In this embodiment, when the sunshade cloth 5 needs to be cleaned, the self-locking motor 3 is started to drive the winding roller 4 to rotate, and the winding roller 4 drives the sunshade cloth 5 to be gradually wound up. At the same time, the winding roller 4 drives the driving gears 6 at both ends thereof to rotate, and the two driving gears 6 respectively drive the corresponding driven gears 9 meshing therewith to rotate, and the driven gears 9 respectively drive the upper and lower slave rotating rods 7 to rotate, and the slave rotating rods 7 drive the cleaning brush 8 to rotate, and the cleaning brush 8 gradually cleans the dust and dirt on the upper and lower surfaces of the sunshade cloth 5 to avoid clogging the gaps in the sunshade cloth 5, thereby affecting the ventilation effect in the greenhouse.

[0029] Among them reference Figure 4-Figure 7 It can be seen that in the present application, the leveling component includes an arc roller 12, the two ends of the arc roller 12 are rotatably mounted on the outer surfaces of the opposite sides of the two mounting plates 11, the outer surface of the arc roller 12 is against the upper surface of the sunshade cloth 5, the outer surface of the end of the arc roller 12 away from the self-locking motor 3 is fixedly mounted with a first pulley 13, the outer surface of the end of the winding roller 4 away from the self-locking motor 3 is fixedly mounted with a second pulley 14, a belt 15 is sleeved between the outer surface of the first pulley 13 and the outer surface of the second pulley 14, the inner wall of the greenhouse body 1 is fixedly mounted with a support frame 16, and the front surface of the greenhouse body 1 Guide plates 17 are fixedly installed on both sides, and a counterweight rod 19 is slidably installed between the outer surfaces of the opposite sides of the two guide plates 17.

[0030] In this embodiment, when the sunshade cloth 5 needs to be rolled up, the self-locking motor 3 is started, the self-locking motor 3 drives the winding roller 4 to rotate, and the winding roller 4 drives the sunshade cloth 5 to be gradually rolled up. At the same time, the winding roller 4 drives the second pulley 14 to rotate, and the second pulley 14 drives the first pulley 13 to rotate through the belt 15, and the first pulley 13 drives the arc roller 12 to rotate. The arc roller 12 has a certain curvature, and the curved surface of the arc roller 12 is against the upper surface of the sunshade cloth 5. The rotation direction of the arc roller 12 is opposite to the moving direction of the sunshade cloth 5. When the arc roller 12 rotates, the arc roller 12 passes through the curved surface against the sunshade cloth 5 to move the sunshade The cloth 5 continuously applies tension to expand on both sides, so that the sunshade cloth 5 remains tight, thereby preventing the sunshade cloth 5 from wrinkling; a counterweight rod 19 is fixedly installed at the bottom of the sunshade cloth 5, and both ends of the counterweight rod 19 are arranged in the guide holes 18 on the guide plate 17.

When the sunshade cloth 5 needs to be unfolded, the self-locking motor 3 reverses, and the winding roller 4 drives the sunshade cloth 5 to unfold gradually. The counterweight rod 19 is driven by gravity to unfold the sunshade cloth 5 along the guide hole 18, thereby shading the greenhouse main body 1.

[0031] It should be noted that the utility model is a greenhouse shading device. When in use, the self-locking motor 3 is started, the self-locking motor 3 drives the winding roller 4 to rotate, and the winding roller 4 drives the sunshade cloth 5 to be gradually wound up. At the same time, the winding roller 4 drives the driving gears 6 at both ends thereof to rotate, and the two driving gears 6 respectively drive the corresponding driven gears 9 meshing therewith to rotate, and the driven gears 9 respectively drive the upper and lower slave rotating rods 7 to rotate, and the slave rotating rods 7 drive the cleaning brush 8 to rotate, and the cleaning brush 8 gradually cleans the dust and dirt on the upper and lower surfaces of the sunshade cloth 5 to avoid clogging the gaps in the sunshade cloth 5, thereby affecting the ventilation effect in the greenhouse.

The arc roller 12 has a certain curvature, and the curved surface of the arc roller 12 is against the upper surface of the sunshade cloth 5. The rotation direction of the arc roller 12 is opposite to the moving direction of the sunshade cloth 5. When the arc roller 12 rotates, the arc roller 12 continuously applies tension to the sunshade cloth 5 to expand on both sides through the curved surface that is against the sunshade cloth 5, so that the sunshade cloth 5 remains tight, thereby preventing the sunshade cloth 5 from wrinkling.

[0033] When the sunshade cloth 5 needs to be unfolded, the self-locking motor 3 reverses, and the winding roller 4 drives the sunshade cloth 5 to be gradually unfolded. The counterweight rod 19 at the bottom of the sunshade cloth 5 moves downward due to gravity, and the counterweight rod 19 drives the sunshade cloth 5 to be unfolded downward along the guide hole 18, thereby shading the greenhouse main body 1.
