DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4, A temperature control box for agricultural seedling raising, including a sealing cover 1. A sealing plate is arranged on the back of the sealing cover 1. The thickness of the sealing plate matches the distance from the side of the seedling raising bottom plate 16 close to the sealing cover 1 to the back of the sealing cover 1. Setting the sealing plate can ensure that the temperature will not be transmitted to the bottom of the temperature control box body 3 when the sealing cover 1 is closed, avoiding temperature loss. One side of the sealing cover 1 is fixedly connected to one end of a hinge 2, and the other end of the hinge 2 is fixedly connected to one side of the temperature control box body 3. The bottom inner wall of the temperature control box body 3 is fixedly connected to the bottom of a motor 4. The output shaft at the top of the motor 4 is fixedly inserted into the center of a driving gear 5. The teeth on one side of the outer circumferential surface of the driving gear 5 mesh with the teeth on one side of the outer circumferential surface of a driven gear 6. The center of the driven gear 6 is fixedly sleeved with the bottom of a limiting column 7. One side of the middle part of the limiting column 7 is provided with an anti - detachment ring. The outer diameter of the anti - detachment ring is larger than the diameter of the limiting column 7, and the inner diameter of the anti - detachment ring matches the diameter of the limiting column 7. Setting the anti - detachment ring can prevent the limiting column 7 from detaching from the fixed platform 8 during rotation. The middle part of the limiting column 7 is rotatably inserted into the middle part of the fixed platform 8. A bearing is arranged in the middle part of the fixed platform 8. The outer circumferential surface of the bearing is fixedly connected to the inner circumferential surface of the middle part of the fixed platform 8, and the inner circumferential surface of the bearing is fixedly connected to the outer circumferential surface of the middle part of the limiting column 7. Setting the bearing can reduce the rotational friction between the limiting column 7 and the fixed platform 8 and improve the rotational efficiency. The bottom of the fixed platform 8 is fixedly connected to the bottom inner wall of the temperature control box body 3.

[0027] The upper surface of the fixed platform 8 is fixedly connected to the bottom of a limiting ear plate 9. The number of the limiting ear plates 9 is six. Two of the limiting ear plates 9 are evenly arranged as a group on the upper surface of the fixed platform 8. Setting six ear plates 9 is convenient for supporting the driving arm 13, enabling the driving arm 13 to stably control the movement of the seedling raising bottom plate 16. The top of the limiting ear plate 9 is rotatably sleeved with one end of a central rotating rod 10. The middle part of the central rotating rod 10 is fixedly inserted into the center of a worm gear 11. The teeth on the outer circumferential surface of the worm gear 11 mesh with the grooves on the outer circumferential surface of a worm 12. The bottom of the worm 12 is fixedly sleeved with the top of the limiting column 7.

[0028] One side of the middle part of the central rotating rod 10 is fixedly inserted into one end of a driving arm 13. The end of the driving arm 13 far from the central rotating rod 10 is rotatably connected to the bottom of a damping rotating rod 14. The top of the damping rotating rod 14 is rotatably connected to the bottom of a positioning seat 15. The top of the positioning seat 15 is fixedly connected to the lower surface of the seedling raising bottom plate 16. A positioning square groove is arranged on the top of the seedling raising bottom plate 16. The thickness of the positioning square groove is one - half of the thickness of the seedling raising bottom plate 16. Setting the positioning square groove can prevent the seedlings inside from bumping against the inner wall of the temperature control box body 3 when the temperature control box accidentally shakes. One side of the seedling raising bottom plate 16 is fixedly connected to one end of a limiting slider 17. The other end of the limiting slider 17 is slidably connected to a limiting sliding groove 18 arranged inside the temperature control box body 3.

[0029] All the electrical components mentioned in this article are electrically connected to an external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control purposes.

[0030] During use, insert the seedling tray into the positioning square groove in the seedling raising bottom plate 16, start the motor 4 to drive the driving gear 5 to rotate, and then drive the driven gear 6 to rotate, causing the limiting post 7 at the axis of the driven gear 6 and the worm 12 at the top of the limiting post 7 to rotate. Thereby driving the worm gear 11 meshing with the worm 12 to rotate, causing the central rotating rod 10 at the axis of the worm gear 11 to rotate under the limitation of the limiting ear plate 9, thereby controlling the driving arm 13 on the central rotating rod 10 to rotate clockwise and counterclockwise. When the driving arm 13 rotates counterclockwise and closes, through the transmission of the damping rotating rod 14, the limiting sliders 17 on both sides of the seedling raising bottom plate 16 slide upward under the limitation of the limiting sliding grooves 18, thereby driving the seedling raising bottom plate 16 to move upward and reducing the distance between the seedling raising bottom plate 16 and the inner wall of the top of the temperature control box body 3. When the driving arm 13 rotates clockwise and unfolds, control the seedling raising bottom plate 16 to move downward to increase the distance between the seedling raising bottom plate 16 and the inner wall of the top of the temperature control box body 3. The internal space size of the temperature control box can be steplessly adjusted according to the height of the seedlings, so as to adapt to the height of seedlings in different growth periods, and at the same time avoid excessive energy consumption.
