Description

Technical Field

[0001] This application relates to the field of seed cultivation technology, and more specifically, to a light regulation device for seed cultivation. Background Technology

[0002] Seeds occupy the very top of the agricultural production chain, serving as the most basic and crucial means of production in agriculture, and forming the foundation for human survival and development. Increasing grain production and income is the fundamental way to ensure national food security. Grain production is inseparable from seeds, and the seed industry, at the starting point of the entire agricultural industry chain, significantly influences and even determines crop yield and quality.

[0003] However, existing seed cultivation boxes use light bulbs to simulate light in order to ensure that the seeds are exposed to light. For example, Chinese patent application number CN202222412918.X discloses a seedling device for vegetables. This method sets a light bulb inside the box, but the position of the light bulb is fixed and cannot simulate the movement of natural light. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a light regulation device for seed cultivation, which aims to improve the problems mentioned in the background art.

[0005] This application provides a light adjustment device for seed cultivation, including a box, in which multiple layers of cultivation trays are arranged, and multiple tracks are arranged in the box. Each track is movably connected to a lamp holder, and a strip lamp is arranged on the lamp holder. Each cultivation tray is correspondingly provided with one strip lamp. A translation mechanism is arranged on the outer wall of the box, and the translation mechanism is magnetically coupled to the lamp holder.

[0006] In one specific implementation, the translation mechanism includes a carriage and a lead screw. The carriage is provided with a magnet that is magnetically coupled to each of the lamp holders. The lead screw is rotatably connected to the housing and threadedly connected to the carriage.

[0007] In one specific implementation, the translation mechanism further includes a motor, which is mounted on the housing, and the output end of the motor is fixedly connected to the lead screw.

[0008] In one specific implementation, the translation mechanism further includes a guide rod, which is fixedly connected to the housing, and the slide is slidably connected to the guide rod.

[0009] In the above process, the motor drives the lead screw to rotate, which in turn drives the carriage to slide along the guide rod. This allows all the lamp holders and strip lights inside the box to move from the east side of the box to the west side, thus simulating the effect of the sun rising in the east and setting in the west.

[0010] In one specific implementation, a roller is rotatably connected to the lamp holder, and a groove adapted to the roller is provided on the track.

[0011] In the above implementation process, the lamp holder is secured to the track by rollers and can roll laterally along the track with small movement damping so that it can be driven to translate by the carriage.

[0012] In one specific implementation, the track is hollowed out, and a partition is provided at the hollowed-out position. The magnet is magnetically connected to the lamp holder through the partition.

[0013] In the above implementation process, the track is made of aluminum alloy. To reduce the resistance to magnetic force, plastic partitions are set in the hollowed-out parts of the track, and corresponding through slots are also opened on the box. This can shorten the distance between the magnet and the lamp holder and ensure the magnetic attraction effect.

[0014] In one specific implementation, a conductive strip is fixedly connected to the track, and an elastic brush is provided on the lamp holder to abut against the conductive strip.

[0015] In the above process, the power supply is connected to the conductive strip, and the lamp holder is pressed against the conductive strip through the brush to provide power to the strip light.

[0016] In one specific implementation, the strip light is a light strip composed of multiple LED beads.

[0017] In the above implementation process, LEDs can be selected from multiple color temperatures to simulate the color temperature of nature. It should be noted that, if necessary, a logic driving circuit can be set in the strip light so that the bright spot of the strip light can move on the strip light, similar to the effect of a marquee. This combination of the translation of the strip light can better simulate the trajectory of the sun in a day.

[0018] Compared with the prior art, the beneficial effects of this application are: a strip light is set for each layer of the cultivation tray inside the box, and a translation mechanism is set outside the box to drive all the light holders and strip lights inside the box to move from the east side to the west side of the box through magnetic coupling, thereby simulating the effect of the sun rising in the east and setting in the west, so as to better adapt to the cultivation of seeds; this can maintain the airtightness of the box, make full use of the space inside the box, and avoid the problem of easy failure of the translation mechanism in the humid and hot environment inside the box.

[0022] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0023] Please see Figures 1-4 This application provides a light adjustment device for seed cultivation, including a housing 10. The housing 10 contains multiple layers of cultivation trays 20 and multiple tracks 30. Each track 30 is movably connected to a lamp holder 40, and each lamp holder 40 is equipped with a strip light 50. Each cultivation tray 20 has a corresponding strip light 50. A translation mechanism 60 is provided on the outer wall of the housing 10, and the translation mechanism 60 is magnetically coupled to the lamp holders 40. Specifically, each layer of cultivation tray 20 inside the housing 10 has a strip light 50. The translation mechanism 60, located outside the housing 10, drives all the lamp holders 40 and their strip lights 50 inside the housing 10 to move from the east side to the west side of the housing 10 via magnetic coupling, thus simulating the effect of sunrise and sunset, better adapting to seed cultivation. This maintains the airtightness of the housing 10, makes full use of the space inside the housing 10, and avoids the problem of the translation mechanism 60 easily malfunctioning in the humid and hot environment inside the housing 10.

[0024] Please see Figures 1-4 The translation mechanism 60 includes a slide 61 and a lead screw 62. A magnet 63 is mounted on the slide 61 and magnetically coupled to each lamp holder 40. The lead screw 62 is rotatably connected to the housing 10 and threadedly connected to the slide 61. The translation mechanism 60 also includes a motor 64, mounted on the housing 10, with its output end fixedly connected to the lead screw 62. The translation mechanism 60 further includes a guide rod 65, fixedly connected to the housing 10, with the slide 61 slidably connected to the guide rod 65. The motor 64 drives the lead screw 62 to rotate, thereby driving the slide 61 to slide along the guide rod 65. This allows all the lamp holders 40 and their strip lights 50 within the housing 10 to move from the east side to the west side of the housing 10, simulating the effect of the sun rising in the east and setting in the west.

[0025] Please see Figures 1-4 A roller 41 is rotatably connected to the lamp holder 40, and a groove adapted to the roller 41 is provided on the track 30. The lamp holder 40 is engaged on the track 30 by the roller 41 and can roll laterally along the track 30 with small movement damping so that it can be driven to translate by the carriage 61.

[0026] Please see Figures 1-4 The track 30 is hollowed out, and a partition 31 is placed in the hollowed-out area. The magnet 63 is magnetically connected to the lamp holder 40 through the partition 31. The track 30 is made of aluminum alloy. To reduce the resistance to the magnetic force, a plastic partition 31 is placed in the hollowed-out area of ​​the track 30. The housing 10 also has a corresponding through groove, which can shorten the distance between the magnet 63 and the lamp holder 40 and ensure the magnetic attraction effect.

[0027] Please see Figures 1-4 A conductive strip 32 is fixedly connected to the track 30, and a flexible brush 42 is provided on the lamp holder 40 to abut against the conductive strip 32. The power supply is connected to the conductive strip 32, and the lamp holder 40 provides power to the strip light 50 by abutting against the conductive strip 32 through the brush 42.

[0028] Please see Figures 1-4 The strip light 50 is a light strip composed of multiple LED beads. The LEDs can be selected from multiple color temperatures to simulate the color temperature of nature. It should be noted that, if necessary, a logic driving circuit can be set in the strip light 50 so that the bright spot of the strip light 50 can move within the strip light 50, similar to the effect of a marquee. This combination with the translation of the strip light 50 can better simulate the trajectory of the sun throughout the day.

[0029] The working principle of the light adjustment device for seed cultivation is as follows: the motor 64 drives the lead screw 62 to rotate, which in turn drives the slide 61 to slide along the guide rod 65. Through magnetic action, all the lamp holders 40 and their strip lights 50 in the box 10 are moved from the east side to the west side, thereby simulating the effect of the sun rising in the east and setting in the west, which is better suited to seed cultivation.

[0030] In summary, each layer of the cultivation tray 20 inside the box 10 is equipped with a strip light 50. A translation mechanism 60 is set outside the box 10 to drive all the light holders 40 and their strip lights 50 inside the box 10 to move from the east side to the west side of the box 10 through magnetic coupling, thereby simulating the effect of the sun rising in the east and setting in the west, so as to better adapt to the seed cultivation. This can maintain the airtightness of the box 10, make full use of the space inside the box 10, and avoid the problem of the translation mechanism 60 being prone to failure in the humid and hot environment inside the box 10.
