Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to an adjustable-angle supplemental lighting device for crop planting. Background Technology

[0002] In modern agricultural production, sunlight is one of the key factors affecting crop growth, development, and yield. Natural sunlight is limited by season, weather, and geographical conditions. Especially in greenhouses, polytunnels, or indoor growing environments, insufficient or uneven sunlight can lead to slow crop growth, reduced quality, and even yield reduction. Therefore, artificial lighting technology has become an important component of modern agriculture, especially protected agriculture.

[0003] Existing supplemental lighting devices are usually fixed or hinged to supports above crops. As crops grow, their height changes. If the supplemental lights are too far from the crops, the light gradually weakens with increasing distance, making it difficult for them to provide effective supplemental lighting. If the supplemental lights are too close to the crops, they also become ineffective as the crops grow taller than them. Therefore, there is a need for a supplemental lighting device that can be adjusted in height to provide supplemental lighting for crops from different angles. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a novel adjustable-angle supplemental lighting device for crop cultivation. This device allows for the adjustment of the height of the supplemental light using a reel, a locking mechanism, and a suspension wire, thereby providing supplemental lighting to crops according to their growth. It is simple, efficient, safe, reliable, and easy to operate.

[0005] This utility model is achieved through the following technical solution: providing an adjustable-angle supplemental lighting device for crop planting, including a planting trough with a support frame; a reel is mounted on the support frame, the reel is connected to the support frame via a latch, a suspension line is wound on the reel, and a supplemental light is mounted on the end of the suspension line away from the reel; the height of the supplemental light is adjusted by the reel, latch, and suspension line, thereby providing supplemental lighting to the crops according to their growth.

[0006] As an optimization, the locking mechanism includes a spiral spring, a ratchet, and a spring-loaded self-locking mechanism. The spiral spring is coaxially mounted on the reel, with its two ends connected to the reel and the bracket, respectively. The ratchet is coaxially fixed to the reel, and the spring-loaded self-locking mechanism is mounted on the bracket. The ratchet and the spring-loaded self-locking mechanism are compatible, and their movement trajectories intersect. When the fill light is pulled down, the hanging line drives the reel to rotate, the spiral spring contracts, and after the fill light is released, the ratchet and the spring-loaded self-locking mechanism lock the reel. When the fill light is pulled down again, the spring-loaded self-locking mechanism disengages from the ratchet, the spiral spring relaxes, and the reel rotates in the opposite direction under the action of the spiral spring, causing the hanging line to drive the fill light upward. Thus, the height of the fill light can be easily adjusted through the spiral spring, ratchet, and spring-loaded self-locking mechanism.

[0007] As an optimization, a base is provided at the end of the suspension line away from the reel, and the supplementary light is mounted on the base; the illumination angle of the supplementary light can be adjusted by rotating the supplementary light on the base.

[0008] As an optimization, the base and the fill light are provided with sliding holes, and an oil-filled rotating shaft slides through the sliding holes. One end of the rotating shaft is connected to the base through a return spring, and a baffle is provided at the end of the rotating shaft away from the base. The baffle is located inside the fill light, and the size of the baffle is larger than the diameter of the sliding hole. The rotating shaft and the return spring increase the friction between the base and the fill light, preventing the fill light from rotating on the base.

[0009] As an optimization, the base is provided with several limiting grooves arranged around the axis of the sliding hole, and the fill light is provided with limiting protrusions that are adapted to the limiting grooves, and the movement trajectories of the limiting grooves and the limiting protrusions intersect; the limiting grooves and the limiting protrusions increase the friction between the base and the fill light, preventing the fill light from rotating on the base.

[0010] As an optimization, the support is equipped with a horizontally extending slide rail, on which a slider slides, and a spool and a locking buckle are located on the slider; the horizontal spacing between the supplementary light and the crops can be adjusted by the slide rail and the slider.

[0011] The beneficial effects of this utility model are as follows: the height of the supplementary light can be adjusted by means of a reel, a locking buckle, and a suspension line, thereby providing supplementary lighting to crops according to their growth; pulling down the supplementary light causes the suspension line to rotate the reel, the spiral spring to contract, and after releasing the supplementary light, the ratchet and the spring-loaded self-locking mechanism lock the reel; pulling the supplementary light again causes the spring-loaded self-locking mechanism to disengage from the ratchet, the spiral spring to relax, and the reel to rotate in the opposite direction under the action of the spiral spring, while the suspension line drives the supplementary light to move upward; thus, the height of the supplementary light can be easily adjusted by means of the spiral spring, ratchet, and spring-loaded self-locking mechanism; the illumination angle of the supplementary light can be adjusted by rotating the supplementary light on the base; and the horizontal distance between the supplementary light and the crops can be adjusted by means of a slide rail and a slider.

[0021] like Figure 1 and Figure 2 The lock 4 shown includes a spiral spring 401, a ratchet 402, and a spring-loaded self-locking mechanism 403. The spiral spring 401 is coaxially mounted on the pulley 3, and its two ends are connected to the pulley 3 and the bracket 2, respectively. The ratchet 402 is coaxially fixed to the pulley 3.

The axes of the spiral spring 401 and the ratchet 402 extend in the horizontal direction.

[0022] Pull down the supplementary light 7, the suspension line 5 drives the reel 3 to rotate, the spiral spring 401 contracts, until the supplementary light 7 reaches the designated height. Release the supplementary light 7, the reel 3 rebounds under the action of the spiral spring 401, the ratchet 402 and the rebound self-locking mechanism 403 lock the reel 3, the reel 3 stops rotating, and the supplementary light 7 stays at the designated height; turn on the supplementary light 7 to provide supplementary lighting for the crops; after the crops grow to a certain height, the height of the supplementary light 7 needs to be adjusted; pull the supplementary light 7 again, the rebound self-locking mechanism 403 disengages from the ratchet 402, the spiral spring 401 relaxes, the reel 3 rotates in the opposite direction under the action of the spiral spring 401, the suspension line 5 drives the supplementary light 7 to move upward; until the suspension line 5 is completely wrapped around the reel 3.

[0023] like Figures 1-4 The end of the suspension line 5 away from the reel 3 is provided with a base 6, and the supplementary light 7 is mounted on the base 6; the supplementary light 7 has a cylindrical structure and extends in the horizontal direction.

[0024] Rotate the fill light 7, which rotates on the base 6, and adjust the illumination angle of the fill light 7.

[0025] like Figures 2-4 The base 6 and the supplementary light 7 shown are provided with sliding holes. An oil rotating shaft 8 slides through the sliding holes. One end of the rotating shaft 8 is connected to the base 6 through a return spring 9. A baffle 10 is provided at the end of the rotating shaft 8 away from the base 6. The baffle 10 is located inside the supplementary light 7, and the size of the baffle 10 is larger than the diameter of the sliding hole.

[0026] Rotate the fill light 7, and the fill light 7 will rotate on the base 6. The return spring 9 will press the rotating shaft 8 and the base 6. The rotating shaft 8 will pull the base 6 and the fill light 7 together through the baffle 10. The fill light 7 will be fixed on the base 6. Adjust the illumination angle of the fill light 7.

The fill light 7 will be engaged with the base 6 through the limiting protrusion 12 and the limiting groove 11.

[0029] like Figure 1 and Figure 2The bracket 2 shown is provided with a slide rail 13 extending in the horizontal direction, and a slider 14 is slidably mounted on the slide rail 13. The spool 3 and the lock 4 are located on the slider 14. The spool 3 is rotatably mounted on the slider 14. The axis of the slide rail 13 and the axis of the supplementary light 7 are perpendicular to each other.

[0030] Push the slider 14, and the slider 14 slides on the slide rail 13. The slider 14 drives the spool 3 and the lock 4 to slide on the slide rail 13. The spool 3 drives the supplementary light 7 to slide along the slide rail 13 axially through the suspension line 5 until the supplementary light 7 and the crops are adjusted to the specified distance in the horizontal direction.

[0031] In actual production, the slider 14 is pushed, and slides on the slide rail 13. The slider 14 drives the thread wheel 3 and the locking buckle 4 to slide on the slide rail 13.

The supplementary light 7 is pulled down, and the suspension line 5 drives the thread wheel 3 to rotate, and the spiral spring 401 contracts until the supplementary light 7 reaches the specified height. The supplementary light 7 is released, and the thread wheel 3 rebounds under the action of the spiral spring 401. The ratchet 402 and the spring-loaded self-locking mechanism 403 lock the spool 3, stopping its rotation and the supplementary light 7 stops at the designated height. The supplementary light 7 is then turned on to provide supplementary lighting for the crops.

The supplementary light 7 is pulled again, causing the spring-loaded self-locking mechanism 403 to disengage from the ratchet 402, and the spiral spring 401 to relax. The spool 3 rotates in the opposite direction under the action of the spiral spring 401, and the suspension line 5 drives the supplementary light 7 upward until the suspension line 5 is completely wrapped around the spool 3.
