Description

Technical Field

[0001] This application relates to the field of agricultural planting equipment technology, and in particular to an adjustable lighting frame for tomato planting. Background Technology

[0002] In greenhouse agriculture, sunlight is one of the key factors affecting tomato growth. Currently, many existing lighting systems in tomato cultivation are fixed structures, making it difficult to adjust the light distance according to plant height. This fails to meet the light intensity requirements of tomato plants at different growth stages, impacting fruit quality and yield. Furthermore, the fixed and unadjustable positions of the light lamps lead to uneven light exposure, hindering photosynthesis. Therefore, there is an urgent need for an adjustable lighting system for tomato cultivation. Utility Model Content

[0003] This application provides an adjustable lighting frame for tomato cultivation. The frame is equipped with an electric cylinder and a servo motor. Through the control of the electric cylinder and the servo motor, the height and horizontal position of the light lamps can be adjusted bidirectionally to meet the light intensity requirements of tomato plants at different growth stages, ensure the light effect of tomatoes, and improve the fruit quality and yield of tomatoes. The servo motor drives the screw to rotate in the forward or reverse direction, which in turn drives the screw sleeve on the screw to move laterally, adjusting the lateral position of the light lamps, improving the uniformity of light, and helping tomatoes to promote photosynthesis.

[0004] This application provides an adjustable lighting frame for tomato cultivation, comprising: a support cylinder and a base. The support cylinder comprises two cylinders, which are symmetrically fixed to the base. Each support cylinder includes an outer cylinder and an inner cylinder, with the inner cylinder fitted inside the outer cylinder. An electric cylinder is installed at the bottom of the outer cylinder, and the output end of the electric cylinder is connected to the bottom of the inner cylinder. A bearing seat is fixedly installed at the top of each of the two inner cylinders, and a screw passes through the two bearing seats. A servo motor is connected to one end of the screw. Several threaded sleeves are evenly fitted on the screw. A plate is welded to the side wall of each threaded sleeve, and a light is installed below the plate. A ring is welded to the bottom of each threaded sleeve, and each ring is movably fitted onto the same crossbar. The two ends of the crossbar are fixed to the opposite side walls of the two support cylinders.

[0005] Furthermore, a U-shaped seat is welded to the top of the support cylinder, and the bearing seat is fixed inside the U-shaped seat.

[0006] Furthermore, a limiting plate is provided on each of the opposite side walls inside the outer cylinder.

[0007] Furthermore, a base plate is welded to the bottom of the inner cylinder, and the cross-sectional area of ​​the base plate is larger than the cross-sectional area of ​​the bottom of the inner cylinder.

[0008] Furthermore, the lighting is LED, with several lighting lights connected in strings.

[0009] Furthermore, the screw sidewall is provided with external threads, and the inner wall of each screw sleeve is provided with internal threads.

[0010] As can be seen from the above technical solution, this application provides an adjustable lighting frame for tomato cultivation, including a support cylinder and a base. The support cylinder comprises two cylinders, symmetrically fixed to the base, which is fixed in the tomato planting area. The two support cylinders are symmetrically fixed on both sides of the base, facilitating the illumination of the tomatoes planted below by the light lamps on the screws at the top of the support cylinders. Each support cylinder includes an outer cylinder and an inner cylinder, with the inner cylinder fitted inside the outer cylinder. An electric cylinder is installed at the bottom of the outer cylinder, with its output connected to the bottom of the inner cylinder. Both electric cylinders are connected to a power source. Simultaneous activation of both cylinders causes the connected inner cylinder to rise and fall, adjusting the height of the support cylinder and thus the vertical height of the light lamps, meeting the light intensity requirements of tomato plants at different growth stages. A bearing seat is fixedly installed at the top of each of the two inner cylinders, with a screw threaded through each bearing seat. A servo motor is connected to one end of the screw, which is connected to a power source. Forward rotation of the servo motor drives the screw to rotate forward, and reverse rotation drives the screw to rotate backward. Several... Each screw sleeve has a rotating screw that engages with the internal thread of the sleeve's inner wall through the external thread on its sidewall, driving the sleeve to move laterally. Each sleeve has a plate welded to its sidewall, with a light lamp installed below the plate. A ring is welded to the bottom of each sleeve, and these rings are movably fitted onto a crossbar. The crossbar's ends are fixed to the opposite sidewalls of two support cylinders. Several light lamps are connected in series by wires, providing power. When these light lamps are turned on, they supplement the tomato plants with light. The lateral movement of the sleeves causes the light lamps below the welded plates on their sidewalls to move laterally as well. Adjusting the lateral position of the light lamps, guided by the rings on the sleeve's sidewalls and the crossbar, ensures smooth movement of the light lamps, improving the uniformity of light exposure to the tomato plants and promoting photosynthesis. Through the control of an electric cylinder and a servo motor, the height and horizontal position of the light lamps can be adjusted bidirectionally to meet the light intensity requirements of tomato plants at different growth stages, ensuring effective light exposure and improving fruit quality and yield.

[0011] In summary, the beneficial effects of this application are as follows:

[0012] 1. The frame is equipped with an electric cylinder and a servo motor. Through the control of the electric cylinder and the servo motor, the height and horizontal position of the light lamp can be adjusted in both directions to meet the light intensity requirements of tomato plants at different growth stages, ensure the light effect of tomatoes, and improve the fruit quality and yield of tomatoes.

[0013] 3. The screw of the frame is equipped with multiple screw sleeves. The servo motor drives the screw to rotate in the forward or reverse direction, which in turn drives the screw sleeves on the screw to move laterally. In conjunction with the crossbar guide structure, the lateral position of the light lamp is adjusted to ensure that the light lamp moves smoothly and improves the uniformity of illumination.

[0020] As can be seen from the above technical solutions, see [link / reference]. Figures 1-2 .

[0021] Example 1:

[0022] An adjustable lighting frame for tomato cultivation includes two support cylinders 1 and a base 13. The two support cylinders 1 are symmetrically fixed to the base 13, which is fixed in the tomato planting area. The two support cylinders 1 are symmetrically fixed on both sides of the base 13, allowing the light lamps 10 on the top screws 5 of the support cylinders 1 to supplement the light for the tomatoes planted below. Each support cylinder 1 includes an outer cylinder 2 and an inner cylinder 3, with the inner cylinder 3 fitted inside the outer cylinder 2. An electric cylinder 12 is installed at the bottom of the inner cylinder 2, and its output is connected to the bottom of the inner cylinder 3. The two electric cylinders 12 are connected to an electric... The power source simultaneously activates two electric cylinders 12. The output ends of the two electric cylinders 12 drive the connected inner cylinder 3 to lift and lower, thereby adjusting the height of the support cylinder 1 and raising and lowering the vertical height of the light lamp 10 to meet the light intensity requirements of tomato plants at different growth stages. A bearing seat 4 is fixedly installed at the top of each of the two inner cylinders 3. A screw 5 passes through the two bearing seats 4. One end of the screw 5 is connected to a servo motor 11, which is connected to a power source. When the servo motor 11 rotates forward, it drives the screw 5 to rotate forward; when it rotates in reverse, it drives the screw 5 to rotate in reverse. Several threaded sleeves are evenly fitted onto the screw 5. 6. The screw 5 rotates and engages with the internal thread of the inner wall of the screw sleeve 6 through the external thread of its side wall, driving the screw sleeve 6 to move laterally. Each screw sleeve 6 has a plate 9 welded to its side wall, and a light lamp 10 is installed below the plate 9. A ring 8 is welded to the bottom of each screw sleeve 6, and each ring 8 is movably fitted onto the same crossbar 7. The two ends of the crossbar 7 are fixed to the opposite side walls of two support cylinders 1. Several light lamps 10 are connected in series by wires and connected to a power source. When the light lamps 10 are turned on, they provide supplemental light to the tomato plants. The lateral movement of the screw sleeve 6 drives the light lamp below the plate 9 welded to its side wall. The lamp 10 moves laterally, adjusting its lateral position. It is then movably connected to the crossbar 7 via the ring 8 on the side wall of the screw sleeve 6. The crossbar 7 guides the lamp 10, ensuring its smooth movement and improving the uniformity of light exposure to the tomato plants. This promotes photosynthesis in tomatoes. The vertical height and horizontal position of the lamp 10 can be adjusted bidirectionally by the electric cylinder 12 and the servo motor 11, meeting the light intensity requirements of tomato plants at different growth stages, ensuring effective light exposure, and improving fruit quality and yield.

[0023] In a preferred embodiment, a U-shaped seat is welded to the top of the support cylinder 1, and the bearing seat 4 is fixed inside the U-shaped seat, so that the screw 5 can pass through the bearing seat 4 and rotate.

[0024] In a preferred embodiment, a limiting plate 14 is provided on each of the opposite side walls inside the outer cylinder 2. The limiting plate 14 restricts the rising height of the inner cylinder 3 to prevent the inner cylinder 3 from being pushed out of the outer cylinder 2 and affecting the support stability of the support cylinder 1 on the screw 5.

[0025] In a preferred embodiment, a bottom plate is welded to the bottom of the inner cylinder 3. The cross-sectional area of ​​the bottom plate is larger than the cross-sectional area of ​​the bottom of the inner cylinder 3. The bottom plate cooperates with the limiting plate 14 so that the bottom plate is stuck below the limiting plate 14, thereby limiting the rising height of the inner cylinder 3.

[0026] As a preferred embodiment, the lighting lamp 10 is an LED lamp, and several lighting lamps 10 are connected in series, making the LED lamp more energy-efficient.

[0027] In a preferred embodiment, the screw 5 has external threads on its sidewall and each screw sleeve 6 has internal threads on its inner wall.
