[0002] In modern agricultural production, solar greenhouses play a crucial role. Solar greenhouses mainly rely on sunlight to increase the indoor temperature to meet the growth needs of crops. The rolling up and down operations of the heat preservation quilts or straw curtains in the greenhouse are crucial for temperature regulation and light control in the greenhouse.
[0003] Traditional solar greenhouse rolling curtain devices are divided into two categories. One is the rope - rolling type rolling curtain machine. During the unfolding process, the power source mainly relies on the self - gravity of the heat preservation quilt and the rolling curtain shaft, and it is easy to have phenomena such as stagnation in the gentle area of the shed surface. During the rolling - up process, the heat preservation quilt is rolled up by the process of lifting the rope gathered under the heat preservation cup, and the heat preservation quilt is not easy to be rolled tightly. The other is the self - walking type rolling curtain machine on the shed surface. The self - walking type rolling curtain machine on the shed surface drives the rolling curtain shaft to realize the unfolding and rolling - up operations of the heat preservation quilt. There are interval gaps in the heat preservation quilt at the connection position in the middle of the greenhouse. One side of the rolling curtain machine is drivingly connected to one side of the rolling curtain shaft, and one side of the rolling curtain shaft is stressed, and the stress is uneven. After multiple rolling curtain operations, the rolling curtain shaft is prone to deviation, which not only affects the normal use of the greenhouse, but also is easy to damage the greenhouse structure and crops. Therefore, a solar greenhouse rolling curtain device is proposed to solve the above problems. Content of the Utility Model

A baffle 23 is rotatably connected to the top of the wall 1. A rotating shaft 7 is fixedly connected to the inside of the baffle 23. A torsion spring 14 is sleeved on the outside of the rotating shaft 7. Under the action of the torsion spring 14, the baffle 23 can be closely attached to the heat preservation quilt 5. A support assembly is fixedly connected to the top of the wall 1, which is used to support the rolling curtain to prevent it from falling. Arc-shaped tracks 2 are fixedly connected to both the left and right sides of the wall 1. A fixing seat 10 is fixedly connected to the top of the wall 1. Both ends of the rotating shaft 7 are rotatably connected to the middle of the fixing seat 10. The baffle 23 is in contact with the surface of the heat preservation quilt 5, which is used to roll up the heat preservation quilt 5.
[0033] Refer to Figure 4 and Figure 5 , The support assembly includes a second fixing plate 16. The second fixing plate 16 is fixedly connected to the top of the wall 1.
