[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can sense the temperature change of the fill light through the design of the ether liquid in the heat absorbing tube and the pusher. When the temperature of the fill light rises above 35 degrees, the ether liquid vaporizes and expands in volume, pushing the pusher to move in the direction of the guide block. Due to the linkage between the pusher and the roller, the roller rolls under the guidance of the arc surface of the guide block, driving the heat absorbing tube and the fill light to rotate ninety degrees around the central axis of the fixed axis.

[0018] 2. The present invention realizes automatic height adjustment of the fill light by cooperating with the winding shaft and the lifting rope in the lifting device. As the winding shaft rotates, the lifting rope is wound up, and the connecting member gradually rises along the lifting groove, so that the height of the fill light is adjusted accordingly. This automatic lifting function ensures that the fill light can provide the best lighting height for the plants at different growth stages, so that the height of the fill light can be automatically adjusted according to the growth needs of the plants, optimizes the lighting angle and intensity distribution, improves the lighting efficiency, and is conducive to the healthy growth of the plants.

[0019] 3. In the present invention, the elastic action of spring three ensures the stable working state of connector one and connector two during the lifting process. The arc surface and straight surface design of the limit block enable connector one to smoothly push the limit block into the limit groove during the rising process, and reset under the action of spring three to support connector one. This design avoids equipment failure caused by unstable lifting and lowering, and improves the reliability and stability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0035] Reference Figures 1 to 4 In an embodiment of the present invention, a light-filling device for growing fruit and vegetable seedlings comprises: a light-filling lamp 3, a rotating device 2 is provided on the light-filling lamp 3 to drive the light-filling lamp 3 to rotate so that multiple groups of light-filling lamps 3 work alternately, a lifting device 4 is provided on the rotating device 2 to increase the height of the rotating device 2 and the light-filling lamp 3 when the rotating device 2 drives the light-filling lamp 3 to rotate, two groups of lifting devices 4 are provided, symmetrically distributed on both sides of the rotating device 2, and each group of lifting devices 4 is provided with a support frame 1 to support the entire device;

[0036] The rotating device 2 includes a fixed shaft 21 that is rotatably arranged with the lifting device 4, and a synchronous plate 22 is rotatably connected to the fixed shaft 21. The cross section of the synchronous plate 22 is a symmetrical T-shaped. The synchronous plates 22 are provided with six groups, and the side ends of the synchronous plates 22 are fixedly connected with heat absorbing tubes 23. The heat absorbing tubes 23 are provided with three groups. Each group of heat absorbing tubes 23 is fixedly connected with a group of synchronous plates 22 on both sides. The bottom end of the heat absorbing tube 23 is fixedly connected to the fill light 3. A pusher 24 is slidably inserted in the heat absorbing tube 23, and the pusher 24 has a group of round plates and a group of straight rods. The circular plate in the pusher 24 abuts against the inner wall of the heat absorbing tube 23, and ether 25 liquid is arranged between the circular plate in the pusher 24 and the bottom end of the heat absorbing tube 23. The top end of the straight rod in the pusher 24 penetrates the heat absorbing tube 23 and is rotatably connected with a roller 26. A guide block 27 is fixedly connected to the side end of the fixed shaft 21, and the guide block 27 is located at the lowest point of the fixed shaft 21. The roller 26 abuts against the guide block 27. There are three groups of guide blocks 27, and each group of guide blocks 27 is arranged between two groups of synchronous plates 22. The guide blocks 27 are comma-shaped.

[0037] Among them, when the temperature of the fill light 3 rises to more than thirty-five degrees due to long-term use, the ether 25 liquid is vaporized, causing the volume of the ether 25 to expand, thereby pushing the pushing member 24 to move in the direction of the guide block 27. Since the abutting surface is an arc surface and the heat absorption tube 23 is fixedly connected to the synchronous plate 22, a thrust is generated between the roller 26 and the guide block 27, and under the guidance of the arc surface of the guide block 27, the roller 26 rolls along the arc surface of the guide block 27, thereby driving the heat absorption tube 23 to move. Since the heat absorption tube 23 and the synchronous plate 22 are fixedly connected, the synchronous plate 22 and the heat absorption tube 23 thereon and the fill light 3 are rotated ninety degrees around the central axis of the fixed shaft 21.

[0038] Reference Figure 5 The guide block 27 has a mounting groove 271 at the side end, and a stopper 272 is slidably inserted in the mounting groove 271. The contact end of the stopper 272 and the roller 26 has a straight surface on one side and an arc surface on the other side. A group of rollers 26 located at the lowest point of the fixed shaft 21 abuts against the straight surface of the stopper 272. A spring 1 273 is fixedly connected to the top of the stopper 272. One end of the spring 1 273 is fixedly connected to the top of the mounting groove 271. A telescopic rod 241 is fixedly connected to the bottom end of the pusher 24. One end of the telescopic rod 241 is fixedly connected to the top of the fill light 3. A spring 242 is sleeved on the outside of the telescopic rod 241. One end of the spring 242 is fixedly connected to the bottom end of the pusher 24. The other end of the second spring 242 is fixedly connected to the top of the fill light 3. When the fill light 3 rotates, the ether 25 in the heat absorption tube 23 of the next group of fill light 3 becomes liquid again due to long-term cooling. At this time, the second spring 242 is no longer under force and restores its original length, thereby pulling the pushing member 24 to reset and move to the top of the seedling box 11. During the movement, the roller 26 on the heat absorption tube 23 connected to the next group of fill light 3 abuts against the arc surface on the block 272 and pushes the block 272 to move upward until the fill light 3 moves to the top of the seedling box 11. The block 272 is reset under the action of the first spring 273, so that the roller 26 abuts against the straight surface of the block 272.

[0039] The above scheme is adopted: the arc surface design of the guide block 27 can guide the roller 26 to roll along a fixed path, ensuring that the fill light 3 can accurately and smoothly rotate ninety degrees when the temperature rises, thereby avoiding instability or deviation of the fill light 3 during movement. Through the coordinated use of the telescopic rod 241 and the spring 242, the pusher 24 can be automatically reset after the fill light 3 rotates, so that it returns to the initial position and prepares for the next push, which helps to maintain the long-term stable operation of the equipment.

[0040] Reference Figure 6 to Figure 7A seedling box 11 is fixedly connected to the side end of the support frame 1. The support frame 1 is provided with two groups, which are symmetrically distributed on both sides of the seedling box 11. A lifting groove 12 is opened at the top of each group of support frames 1. The lifting groove 12 runs through the support frame 1 from top to bottom. A limiting groove 13 is opened at the side end of the lifting groove 12. There are multiple groups of limiting grooves 13, which are symmetrically distributed on both sides of the lifting groove 12. A group of limiting blocks 14 are slidably inserted in each group of limiting grooves 13. The bottom end of the limiting block 14 is an arc surface and the top end is a straight surface. One end of each group of limiting blocks 14 is fixedly connected to a spring three 15, and one end of the spring three 15 is fixedly connected to the inner wall of the limiting groove 13. A sliding groove is opened at the side end of the support frame 1 16, two groups of sliding grooves 16 are provided, which are symmetrically opened on both sides of the support frame 1. During the rising process of the connecting member 42, the connecting member 42 is connected with the arc surface of the limit block 14, and the limit block 14 is pushed to retract into the limit groove 13, so that the connecting member 42 moves to the top of this group of limit blocks 14. At this time, the limit block 14 is reset under the action of the spring three 15 to support the connecting member 42. Since the winding shaft 48 is plugged into the limit bar 47, the winding shaft 48 rotates together, and the lifting rope 412 is wound on the winding shaft 48. As the lifting rope 412 is wound, the connecting member 42 gradually rises along the lifting groove 12, and the spring four 46 is forced to shrink, and during the rising process, the push rod 414 pushes the winding shaft 48 to move along the direction of the limit strip 47 until the connecting piece 14 abuts against the arc surface of the limit block 14 above it, and pushes the limit block 14 to retract into the limit groove 13, so that the connecting piece 14 moves to the top of this group of limit blocks 14. At this time, the limit block 14 is reset under the action of the spring three 15 to support the connecting piece 14. At the same time, the push rod 414 pushes the winding shaft 48 out of the range of the limit strip 47. At this time, the spring four 46 is no longer restricted by the lifting rope 412, restores its original length, and pushes the connecting piece 2 44 to move upward. During the upward movement, the lifting rope 412 pulls The winding shaft 48 rotates to release the wound lifting rope 412 until the connecting piece 44 moves to the limit block 14 located above the original position of the connecting piece 44. At this time, the distance between the connecting piece 1 42 and the connecting piece 2 44 is restored to its initial state. When the winding shaft 48 rotates to release the lifting rope 412 wound thereon, the synchronous plate 22 drives the winding shaft 48 to rotate, causing the elastic rope 49 deformed and wound on the extension rod 41 to return to its initial state, so that the groove on the inner side of the winding shaft 48 that matches the limit strip 47 corresponds to the limit strip 47, and pulls the winding shaft 48 to reset, so that the limit strip 47 is plugged into the winding shaft 48.

[0041] The above scheme is adopted: by opening a limit groove 13 at the side end of the support frame 1, and the limit block 14 slidably inserted inside it, as well as the elastic action of the spring three 15, the connecting piece 1 42 and the connecting piece 2 44 can be supported and positioned to ensure the accuracy and stability of the height adjustment. The bottom end of the limit block 14 is an arc surface and the top end is a straight surface, so that during the rising process of the connecting piece 1 42, the limit block 14 can be smoothly pushed into the limit groove 13, and reset under the action of the spring three 15 to support the connecting piece 1 42.

[0042] Reference Figure 8The lifting device 4 includes a connector 42 that is slidably plugged into the lifting groove 12. The connector 42 is composed of two groups of circular plates, a group of through shafts, and a group of connecting cylinders. The through shafts penetrate the lifting groove 12 and are rotatably connected to the lifting groove 12, and the bottom ends of the through shafts abut against the straight surfaces of the two groups of limit blocks 14. The two groups of circular plates are symmetrically distributed on both sides of the support frame 1 and are fixedly connected to the through shafts. One side of one group of circular plates is fixedly connected to the connecting cylinder. The fixed shaft 21 is plugged into the connecting cylinder and is rotatably connected to the connecting cylinder. The end face of the connecting cylinder is fixedly connected to the synchronous plate 22. One side of the other group of circular plates of the connector 42 is fixedly connected with an extension Rod 41, the outer side of the extension rod 41 is provided with a connecting piece 43, and the connecting piece 43 is rotatably connected with the extension rod 41, the connecting piece 43 is C-shaped, and the two ends of the connecting piece 43 are respectively slidably connected with a group of sliding grooves 16, and a connecting piece 44 is arranged above the connecting piece 42. The connecting piece 44 is composed of two groups of circular plates and a group of through shafts, wherein the through shaft passes through the lifting groove 12 and is slidably connected with the lifting groove 12, and the bottom end of the through shaft abuts against the straight surface of the other two groups of limit blocks 14, and the two groups of circular plates are symmetrically distributed on both sides of the support frame 1 and are fixedly connected with the through shaft. One side of a group of circular plates in the connecting piece 44 is fixed A connecting piece 45 is connected, and the connecting piece 45 is C-shaped. Both ends of the connecting piece 43 are slidably connected to a group of sliding grooves 16 respectively. The bottom end of the connecting piece 45 is fixedly connected to a spring 46, and one end of the spring 46 is fixedly connected to the connecting piece 43. The side end of the extension rod 41 is fixedly connected to a limit strip 47. Four groups of limit strips 47 are arranged and distributed in a cross shape on the side end of the extension rod 41. The side end of the extension rod 41 is rotatably connected to a winding shaft 48, and the winding shaft 48 is slidably plugged with the limit strip 47. One end of the winding shaft 48 is fixedly connected to an elastic rope 49, and one end of the elastic rope 49 is fixedly connected to the connecting piece 43. Four groups of elastic ropes 49 are arranged, which are evenly distributed at one end of the winding shaft 48. The end face of the extension rod 41 is fixedly connected with a baffle 410. One end of the linkage member 45 is fixedly connected with a pull rope rod 411. The side end of the pull rope rod 411 is fixedly connected with a lifting rope 412.

A pushing groove 415 is opened at the side end of the push rod 414, and the pushing groove 415 abuts against the side end of the winding shaft 48.

[0043] The above scheme is adopted: through the sliding connection between the reel 48 and the limit strip 47, and the fixed connection between one end of the lifting rope 412 and the reel 48, as the fill light 3 rotates, the reel 48 rotates and reels the lifting rope 412, so that the connecting piece 42 gradually rises along the lifting groove 12, and the push rod 414 pushes the reel 48 to move along the direction of the limit strip 47 to ensure the correct reeling and releasing of the lifting rope 412. This automated design reduces the complexity of manual operation and improves the convenience of using the equipment.

[0044] Reference Figures 9 to 12 A toggle switch 31 is provided at the side end of the fill light 3, one end of the connecting piece 43 is fixedly connected to the toggle plate 431, the toggle plate 431 is comma-shaped, the toggle plate 431 abuts against the toggle switch 31, and two groups of toggle plates 431 are provided, which are rotationally symmetrically distributed at both ends of the connecting piece 43. During the rotation process, the toggle switches 31 on the upper group of fill light 3 abut against a group of toggle plates 431, and under the guidance of the arc surface of the toggle plate 431, the toggle switches 31 are toggled to the other side to turn off the fill light 3, while the toggle switches 31 on the lower group of fill light 3 abut against another group of toggle plates 431, and under the guidance of the arc surface of the toggle plate 431, the toggle switches 31 are toggled to the other side to turn on the fill light 3.

[0045] The above scheme is adopted: the toggle plate 431 is used to enable the fill light 3 to automatically switch the switch according to the working status of the equipment. A toggle switch 31 is set at the side end of each group of fill lights 3. When the fill light 3 rotates, the toggle plate 431 will abut against it and guide the toggle switch 31 to the other side through its arc surface. This design ensures that during the rotation process, the previous group of fill lights 3 is automatically turned off, and the next group of fill lights 3 is automatically turned on.

[0046] The working principle of the present invention is as follows: when in use, first turn on a group of fill-in lights 3 located just above the seedling raising box 11 by toggling the switch 31 to illuminate the seedlings in the seedling raising box 11. As the group of fill-in lights 3 are used, the temperature of the fill-in lights 3 gradually increases, thereby heating the ether 25 liquid located between the top of the group of fill-in lights 3 and the pusher 24. When the temperature of the fill-in lights 3 increases to above thirty-five degrees, the ether 25 liquid vaporizes, causing the volume of the ether 25 to expand, pushing the pusher 24 to move upward. Since the roller 26 on the pusher 24 abuts against the arc surface of the guide block 27 and the straight surface of the stopper 272, the thrust generated during the continuous upward movement of the pusher 24 causes the roller 26 to move along the arc surface of the guide block 27 and move upward. Under the restriction of the synchronization plate 22, the fill-in light 3 connected to this group of heat absorbing tubes 23 rotates ninety degrees clockwise, and under the action of the synchronization plate 22, the other three groups of fill-in light 3 rotate synchronously, so that the next group of fill-in light 3 moves to the top of the seedling box 11. During the movement, the roller 26 on the heat absorbing tube 23 connected to the next group of fill-in light 3 abuts against the arc surface on the block 272, and pushes the block 272 to move upward until the fill-in light 3 moves to the top of the seedling box 11. The block 272 is reset under the action of the spring 273, so that the roller 26 abuts against the straight surface of the block 272, and during the rotation process, the toggle switch 31 on the previous group of fill-in light 3 abuts against a group of toggle plates 431, and under the guidance of the arc surface of the toggle plate 431, the toggle switch 31 is toggled to The other side turns off the fill light 3, and the toggle switch 31 on the next group of fill light 3 abuts against another group of toggle plates 431, and under the guidance of the arc surface of the toggle plate 431, the toggle switch 31 is toggled to the other side to turn on the fill light 3. As the fill light 3 continues to rotate, the connecting piece 42 is driven to rotate synchronously. At this time, since the winding shaft 48 is plugged into the limit bar 47, the winding shaft 48 rotates together to wind up the lifting rope 412 on the winding shaft 48. As the lifting rope 412 is wound, the connecting piece 42 gradually rises along the lifting slot 12, and the spring four 46 is forced to shrink. During the rising process, the push rod 414 pushes the winding shaft 48 to move along the direction of the limit bar 47 until the connecting piece 42 abuts against the arc surface of the limit block 14 above it and pushes The limit block 14 is retracted into the limit groove 13, so that the connecting piece 42 moves to the top of this group of limit blocks 14. At this time, the limit block 14 is reset under the action of the spring three 15 to support the connecting piece 42. At the same time, the push rod 414 pushes the winding shaft 48 out of the range of the limit strip 47. At this time, the spring four 46 is no longer restricted by the lifting rope 412, restores its original length, and pushes the connecting piece 44 to move upward. During the upward movement, the lifting rope 412 pulls the winding shaft 48 to rotate, releasing the wound lifting rope 412 until the connecting piece 44 moves to the limit block 14 located above the original position of the connecting piece 44. At this time, the distance between the connecting piece 1 42 and the connecting piece 2 44 is restored to the initial state. When the winding shaft 48 rotates to release the lifting rope 412 wound thereon,The synchronous plate 22 drives the reel 48 to rotate, causing the elastic rope 49 that is deformed and wrapped around the extension rod 41 to return to its initial state, so that the groove on the inner side of the reel 48 that matches the limit strip 47 corresponds to the limit strip 47, and the reel 48 is pulled to reset, so that the limit strip 47 is plugged with the reel 48; through the design of the ether 25 liquid in the heat absorbing tube 23 and the pushing member 24, the temperature change of the fill light 3 can be sensed. When the temperature of the fill light 3 rises to more than 35 degrees, the ether 25 liquid vaporizes and expands in volume, pushing the pushing member The pusher 24 moves toward the guide block 27. Due to the linkage between the pusher 24 and the roller 26, the roller 26 rolls under the guidance of the arc surface of the guide block 27, driving the heat absorbing tube 23 and the fill light 3 to rotate ninety degrees around the central axis of the fixed shaft 21. This automatic rotation mechanism ensures that the fill light 3 can automatically adjust its position when the temperature is too high to avoid damage to the plants caused by overheating, and enables multiple groups of fill lights 3 to work alternately, ensuring that the seedlings in the seedling box 11 can receive continuous and uniform light. The light effect of the fill light 3 is optimized through the mechanism of alternating work. The height of the fill light 3 is adjusted accordingly. The automatic lifting function ensures that the fill light 3 can provide the best lighting height for the plants at different growth stages, and the height of the fill light 3 can be automatically adjusted according to the growth requirements of the plants, thereby optimizing the lighting angle and intensity distribution, improving the lighting efficiency, and being beneficial to the healthy growth of the plants. The elastic effect of the spring three 15 ensures that the connector one 42 and the connector two 44 are in a stable working state during the lifting process. The arc surface and straight surface design of the limit block 14 enable the connector one 42 to smoothly push the limit block 14 into the limit groove 13 during the lifting process, and reset under the action of the spring three 15 to support the connector one 42. This design avoids equipment failures caused by unstable lifting and improves the reliability and stability of the equipment.
