The outer wall of the guide rod 41 slides with the sliding cavity 32, and the front and rear ends of the guide rod 41 are slidably connected with the guide rail 22 through the sliding column 43, so that when the top guide rod 41 is subjected to an upward pulling force, it can slide stably along the sliding cavity 32 and the guide rail 22, so that the curtain 42 can be unfolded and moved on the roof 12, and the light area of ​​the roof 12 is controlled as needed, thereby improving the efficiency of seedling cultivation and planting.

[0043] Among them, the outer wall of the sliding column 43 is fixed with a reinforcing rope 44, and the upper and lower adjacent sliding columns 43 are connected by the reinforcing rope 44, so that when the upper guide rod 41 is subjected to tension, the lower sliding column 43 and guide rod 41 can be pulled by the reinforcing rope 44 to reduce the tension on the curtain 42 and improve the structural stability and life of the curtain 42.

[0044] For further information, please refer to Figure 4 The counterweight assembly 5 includes a counterweight block 51, a frame plate 52, a slide groove 53 and a pull rope 54. The outer wall of the counterweight block 51 is slidably installed in the slide cavity 32. The frame plate 52 is vertically fixed to the left side of the counterweight block 51. The frame plate 52 is provided with two places, and a slide groove 53 is formed between adjacent frame plates 52, so that the counterweight block 51 can slide up and down along the second frame body 31 and the slide cavity 32. The weight of the counterweight block 51 is greater than the overall weight of the control assembly 4. The inner wall of the slide groove 53 is fixed to the second frame body 31, the bottom of the pull rope 54 is fixed to the counterweight block 51, and the top of the pull rope 54 is fixedly connected to the guide rod 41, so that when the tension on the guide rod 41 is cancelled, the counterweight block 51 can pull the bottom guide rod 41 downward through the pull rope 54, so that the guide rod 41 is reset after being stressed, so that the curtain 42 is reset.

[0045] Furthermore, the retractable assembly 6 includes a winding disk 61, a retractable rope 62 and a driving assembly. The winding disk 61 is rotatably installed on the outside of the shed body 11, the top of the retractable rope 62 is fixed to the guide rod 41, and the bottom of the retractable rope 62 is wound on the winding disk 61. The winding disk 61 is driven to rotate by the driving assembly, so that when the curtain 42 needs to be unfolded, the winding disk 61 can be rotated by the driving assembly to apply force to the guide rod 41 through the retractable rope 62 to drive the guide rod 41 to move upward. When it is not needed, the winding disk 61 is reset and reversed, so that the guide rod 41 is reset by the gravity of the counterweight block 51.

[0046] Specifically, the driving assembly includes a ring gear 71, a gear 72, a motor 73 and a mounting seat 74. The ring gear 71 is coaxially fixed to the outside of the winding disk 61, the outside of the gear 72 is meshed with the ring gear 71, the output shaft of the motor 73 is fixed to the gear 72, and the motor 73 is fixed on the mounting seat 74, and the mounting seat 74 is fixed to the outside of the shed body 11. During implementation, the gear 72 is driven to rotate by the motor 73, so that the ring gear 71 drives the winding disk 61 to rotate synchronously, thereby meeting the retraction and release work of the retractable rope 62.

[0047] Among them, a sticking plate 33 is fixedly provided on the second frame 31, and the bottom side of the retracting rope 62 is slidably connected to the sticking plate 33. The top height of the sticking plate 33 is lower than the sliding cavity 32 to avoid blocking the sliding of the guide rod 41, and there is a gap between the bottom of the sticking plate 33 and the roof 12, so that the retracting rope 62 can avoid sliding on the roof 12 when being retracted and causing wear to the roof 12, and at the same time, it can also improve the convenience of retracting and releasing the retracting rope 62.

[0048] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will not explain the control method and wiring arrangement in detail.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
