[0002] The light-controlled flowering and fruiting device is an agricultural technology that uses artificial light sources to adjust the light conditions of plants in order to promote flower bud differentiation, flowering and fruit development. It is widely used in facility agriculture, greenhouse planting and scientific research.

[0003] However, existing light-controlled flowering and fruiting devices often cannot provide light to plants from all angles and are not suitable for plants of different heights and sizes.

[0004] Therefore, it is necessary to provide a light-controlled flower and fruit promoting device to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problems of existing light-controlled flowering and fruiting promotion devices being unable to provide plants with comprehensive light and being unsuitable for plants of different heights and sizes, this utility model provides a light-controlled flowering and fruiting promotion device.

[0006] The light-controlled flowering and fruiting promotion device provided by this utility model includes: a top plate; an outer annular plate fixedly installed at the bottom of the top plate; an inner annular plate fixedly installed at the bottom of the top plate; multiple supplementary lighting mechanisms located at the bottom of the top plate for providing light to the plants; a spacing adjustment mechanism installed at the bottom of the top plate for adjusting the spacing between the multiple supplementary lighting mechanisms; and multiple angle adjustment mechanisms installed on the spacing adjustment mechanism for adjusting the angles of the multiple supplementary lighting mechanisms.

[0007] Preferably, the spacing adjustment mechanism includes: a plurality of screws rotatably mounted on the inner annular plate and rotatably connected to the outer annular plate; a plurality of sliding plates threaded onto the plurality of screws; a first servo motor fixedly mounted on the top plate; a rotating shaft rotatably mounted on the top plate and fixedly connected to the output shaft of the first servo motor; a driving bevel gear fixedly mounted at the bottom end of the rotating shaft; and a plurality of driven bevel gears fixedly mounted on the plurality of screws at one end close to each other and meshing with the driving bevel gear.

[0008] Preferably, a plurality of limiting rods are fixedly installed on the inner annular plate, and the plurality of limiting rods are fixedly connected to the inner wall of the outer annular plate, and the plurality of limiting rods are slidably connected to the plurality of sliding plates respectively.

[0009] Preferably, the angle adjustment mechanism includes: a U-shaped plate fixedly installed at the bottom of the sliding plate; a horizontal shaft rotatably installed on the inner wall of the U-shaped plate; a rotating plate fixedly sleeved on the horizontal shaft; and a second servo motor fixedly installed on one side of the U-shaped plate and connected to the horizontal shaft.

[0010] Preferably, the supplementary lighting mechanism includes: an arc-shaped plate fixedly installed at the bottom of the rotating plate; and multiple red light tubes, multiple blue light tubes, and multiple far-red light tubes installed on the arc-shaped plate.

[0011] Preferably, a plurality of crossbars are fixedly installed on the top plate, a plurality of sleeve plates are fixedly installed on the plurality of crossbars at opposite ends, a plurality of positioning bolts are threaded onto the plurality of sleeve plates, and a support rod is slidably installed on the plurality of sleeve plates.

[0012] Preferably, a base plate is fixedly installed at the bottom end of each of the plurality of support rods, an anchor rod is provided on each of the plurality of base plates, and a controller is installed on the top plate.

[0013] Compared with related technologies, the light-controlled flowering and fruit-promoting device provided by this utility model has the following beneficial effects:

[0014] This invention provides a light-controlled flowering and fruiting promotion device. Multiple supplemental lighting mechanisms provide comprehensive illumination to the plant. By controlling the light duration to simulate the natural photoperiod, it influences the plant's photosensitive pigments, thereby inducing flowering. A spacing adjustment mechanism allows for adjustment of the spacing between the multiple supplemental lighting mechanisms, and multiple angle adjustment mechanisms allow for adjustment of their angles. This makes the device suitable for plants of different sizes and shapes. A first servo motor drives multiple screws to rotate via a shaft, a driving bevel gear, and multiple driven bevel gears. The rotation of these screws causes multiple sliding plates to move closer or further apart, which in turn moves the multiple supplemental lighting mechanisms closer or further apart, thus adjusting the spacing between the mechanisms. Multiple limit rods can further limit the movement of the supplemental lighting mechanisms. Multiple sliding plates provide guidance and limit positioning. A second servo motor drives a horizontal axis to rotate, which in turn drives a rotating plate. The rotation of the rotating plate allows adjustment of the angle of the supplemental lighting mechanism. Red light tubes promote flowering and fruit ripening (activating photosensitive pigment Pfr), while blue light tubes enhance photosynthesis, regulate stomatal opening, and influence flower bud quality. Far-red light tubes can reverse the red light effect, delaying or inhibiting flowering. Loosening multiple positioning bolts allows for height adjustment of multiple sleeve plates, thereby adjusting the height of multiple supplemental lighting mechanisms. Tightening multiple positioning bolts fixes the height of multiple supplemental lighting mechanisms. The device is supported by a base plate, which is fixed to the ground by anchor rods. The device is operated and controlled by a controller. Attached Figure Description
