Description

Technical Field

[0001] This utility model relates to the field of crop cultivation technology, and in particular to a plant lamp for cultivating crop seedlings with adjustable lighting range. Background Technology

[0002] Light environment is one of the essential physical environmental factors for plant growth and development. Controlling plant morphology through light quality regulation is an important technology in protected cultivation. Plant lights simulate the principle that plants need sunlight for photosynthesis, providing supplemental lighting or completely replacing sunlight.

[0003] Chinese patent discloses an adjustable plant grow light (authorization announcement number CN221222577U). By setting an automatic adjustment mechanism, adjustable plant grow lights of the same length can be configured according to needs, improving applicability. Adjustment can be completed without disassembly, and the adjustment steps are simple and quick. By using two drive motors to extend and retract the two auxiliary lamp bodies, they can be adjusted individually or synchronously according to the illumination range, improving the efficiency of adjustment and rapid adjustment of the illumination range.

[0004] According to the above references, the device uses an open-type automatic adjustment mechanism to adjust the horizontal position of the auxiliary light. Although this can adjust the overall lighting range of the plant grow light, foreign objects such as dust and insects can easily adhere to the exposed surface of the automatic adjustment mechanism, which increases the adjustment resistance of the automatic adjustment mechanism. Furthermore, since the plant grow light is usually located directly above the crops, the staff need to remove the crops below and climb up to maintain it, which also increases the maintenance burden on the staff.

[0005] Therefore, a plant lamp with adjustable illumination range for cultivating crop seedlings is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a plant light for cultivating crop seedlings with adjustable lighting range in order to solve the above-mentioned problems. This solves the problem that existing plant lights for cultivating crop seedlings with adjustable lighting range have poor self-protection performance and require high maintenance frequency.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a plant lamp for cultivating crop seedlings with adjustable illumination range, comprising: a main lamp, two auxiliary lamps, and two adjustment mechanisms. The two auxiliary lamps are staggered on both sides of the main lamp. The adjustment mechanism includes a horizontal adjustment component fixedly connected to one end of the main lamp, and an angle adjustment component fixedly connected to the auxiliary lamp is fixedly connected to one end of the horizontal adjustment component.

[0008] Preferably, the horizontal adjustment component includes a mounting cylinder fixedly connected to one end of the main lamp. A threaded column is rotatably connected inside the mounting cylinder. An internal threaded cylinder, which is fixedly connected to the angle adjustment component, is threadedly connected to the surface of the threaded column. A flexible protective sleeve is fixedly connected between the mounting cylinder and the angle adjustment component and is fitted onto the surface of the internal threaded cylinder. The flexible protective sleeve can always cover and enclose the portion of the internal threaded cylinder extending outside the mounting cylinder and can expand and contract accordingly. This can prevent external dust, insects, and other impurities from falling onto the surface of the internal threaded cylinder, allowing the internal threaded cylinder to move with low resistance in the mounting cylinder. This solves the problem that existing adjustable-range plant lights for cultivating crop seedlings have poor self-protection performance and require high maintenance frequency.

[0009] Preferably, the flexible protective sleeve is in the shape of a corrugated cylinder and is made of fluororubber material, which can improve the flexibility and corrosion resistance of the flexible protective sleeve and extend its service life.

[0010] Preferably, a first servo motor is fixedly connected to one end of the threaded column. The first servo motor is fixedly connected to one end of the mounting cylinder. This allows the horizontal illumination range of the auxiliary lamp to be adjusted electrically, making the adjustment operation easier and more stable.

[0011] Preferably, the surface of the internally threaded cylinder is provided with a guide groove, and a guide strip that is fixedly connected to the mounting cylinder is slidably connected inside the guide groove. The number of guide grooves and guide strips is the same and not less than four. The guide grooves and guide strips are distributed in a ring around the axis of the internally threaded cylinder. The guide strips prevent the internally threaded cylinder from rotating through the guide grooves, so that the internally threaded cylinder can smoothly drive the angle adjustment component to move horizontally.

[0012] Preferably, the angle adjustment assembly includes a mounting box fixedly connected to one end of the internal threaded cylinder, one end of the flexible protective sleeve fixedly connected to the mounting box, a worm gear rotatably connected inside the mounting box, a worm wheel rotatably connected to the mounting box on the surface of the worm gear, an L-shaped rotating shaft fixedly connected to the inner side of the worm wheel, one end of the L-shaped rotating shaft extending to the outside of the mounting box and fixedly connected to the auxiliary lamp, and a sealing ring fitted onto the surface of the mounting box. The sealing ring can elastically seal the connection between the L-shaped rotating shaft and the mounting cylinder without affecting the rotation of the L-shaped rotating shaft, thereby reducing the rotational resistance of the auxiliary lamp in angle adjustment and making the adjustment of the illumination angle smoother.

[0013] Preferably, the surface of the L-shaped shaft is fixedly connected to a turntable that is fixedly connected to the mounting box. The turntable is positioned between the sealing ring and the worm gear. This reduces the probability of the L-shaped shaft rotating downwards, allowing the L-shaped shaft to operate smoothly.

[0014] Preferably, a second servo motor is fixedly connected to one end of the worm gear, and the second servo motor is fixedly connected to the surface of the mounting box. This allows the illumination angle of the auxiliary lamp to be adjusted electrically, making the adjustment operation easier and more stable.

[0015] The beneficial effects of this utility model are:

[0016] 1. The flexible protective sleeve can always cover and enclose the portion of the inner threaded cylinder that extends outside the mounting cylinder, and can expand and contract accordingly. This can prevent external dust, insects and other impurities from falling onto the surface of the inner threaded cylinder, allowing the inner threaded cylinder to move with low resistance in the mounting cylinder. This solves the problem that the existing plant lights for cultivating crop seedlings with adjustable lighting range have poor self-protection performance and high maintenance frequency.

[0017] 2. The sealing ring can elastically seal the connection between the L-shaped rotating shaft and the mounting cylinder without affecting the rotation of the L-shaped rotating shaft, thereby reducing the rotational resistance of the auxiliary lamp when adjusting the angle and making the adjustment of the illumination angle smoother.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a plant light for cultivating crop seedlings with adjustable illumination range includes: a main light 100, two auxiliary lights 200, and two adjustment mechanisms 300. The two auxiliary lights 200 are staggered on both sides of the main light 100. The adjustment mechanism 300 includes a horizontal adjustment component 310 fixedly connected to one end of the main light 100, and an angle adjustment component 320 fixedly connected to the auxiliary lights 200 at one end of the horizontal adjustment component 310. Both the main light 100 and the auxiliary lights 200 are plant lights, which are electrical devices commonly used by those skilled in the art to provide light to plants. The specific specifications and models need to be selected according to the actual needs of the user, and will not be elaborated here.

[0025] like Figure 2 and Figure 3 As shown, the horizontal adjustment assembly 310 includes a mounting cylinder 311 fixedly connected to one end of the main lamp 100. A threaded post 312 is rotatably connected inside the mounting cylinder 311. An internally threaded cylinder 313, fixedly connected to the angle adjustment assembly 320, is threadedly connected to the surface of the threaded post 312. A flexible protective sleeve 314, sleeved on the surface of the internally threaded cylinder 313, is fixedly connected between the mounting cylinder 311 and the angle adjustment assembly 320. The flexible protective sleeve 314 is corrugated and made of fluororubber material. A first servo motor 315 is fixedly connected to one end of the threaded post 312, and the first servo motor 315 is fixedly connected to one end of the mounting cylinder 311. A guide groove 316 is formed on the surface of the internally threaded cylinder 313. A guide strip 317, fixedly connected to the mounting cylinder 311, is slidably connected inside the guide groove 316. The number of guide grooves 316 and guide strips 317 is the same and not less than four. The guide grooves 316 and guide strips 317 are arranged in a ring around the axis of the internally threaded cylinder 313.

[0026] When the operator needs to adjust the horizontal illumination range of the auxiliary lamp 200, the operator only needs to control the first servo motor 315 to rotate in the corresponding direction. The first servo motor 315 drives the threaded column 312 to rotate. The threaded column 312 drives the inner threaded cylinder 313 to move along the inside of the mounting cylinder 311 through rotation. During this process, the guide strip 317 prevents the inner threaded cylinder 313 from rotating through the guide groove 316, so that the inner threaded cylinder 313 can smoothly drive the angle adjustment component 320 to move horizontally. The angle adjustment component 320 drives the auxiliary lamp 200 connected to it to move horizontally until the auxiliary lamp 200 is moved to the corresponding position.

[0027] like Figure 2 and Figure 4As shown, the angle adjustment assembly 320 includes a mounting box 321 fixedly connected to one end of the internal threaded cylinder 313, one end of a flexible protective sleeve 314 fixedly connected to the mounting box 321, a worm gear 322 rotatably connected inside the mounting box 321, a worm wheel 323 rotatably connected to the mounting box 321 meshing with the surface of the worm gear 322, an L-shaped rotating shaft 324 fixedly connected to the inner side of the worm wheel 323, one end of the L-shaped rotating shaft 324 extending through to the outside of the mounting box 321 and fixedly connected to the auxiliary lamp 200, a sealing ring 325 fixedly connected to the surface of the mounting box 321 and fitted onto the surface of the L-shaped rotating shaft 324; a turntable 326 fixedly connected to the mounting box 321 and disposed between the sealing ring 325 and the worm wheel 323; a second servo motor 327 fixedly connected to one end of the worm gear 322 and fixedly connected to the surface of the mounting box 321;

[0028] When the operator needs to adjust the illumination angle of the auxiliary lamp 200, the operator only needs to manually control the second servo motor 327 to rotate in the corresponding direction. The second servo motor 327 drives the worm gear 322 to rotate, the worm gear 322 drives the worm wheel 323 to rotate, the worm wheel 323 drives the L-shaped rotating shaft 324 to rotate, and the L-shaped rotating shaft 324 drives the auxiliary lamp 200 to rotate around the axis of the worm wheel 323 until the illumination angle of the auxiliary lamp 200 is adjusted to the preset degree. During the rotation of the L-shaped rotating shaft 324, the sealing ring 325 can prevent external dust, insects and other impurities from entering the connection between the L-shaped rotating shaft 324 and the mounting cylinder 311, so as to reduce the rotational resistance of the auxiliary lamp 200 in angle adjustment and make the angle adjustment work smoother.

[0029] In use, as the horizontal adjustment component 310 adjusts the horizontal illumination range of the auxiliary lamp 200 via the angle adjustment component 320, the flexible protective sleeve 314 extends and retracts in accordance with the change in the distance between the mounting cylinder 311 and the angle adjustment component 320. The flexible protective sleeve 314 can always partially cover and enclose the portion of the inner threaded cylinder 313 that extends outside the mounting cylinder 311. This can prevent external dust, insects, and other impurities from falling onto the surface of the inner threaded cylinder 313, allowing the inner threaded cylinder 313 to move with low resistance within the mounting cylinder 311. This solves the problem that existing plant lamps for cultivating crop seedlings with adjustable illumination range have poor self-protection performance and require frequent maintenance.

[0030] It should be noted that the main light 100, auxiliary light 200, first servo motor 315 and second servo motor 327 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the main light 100, auxiliary light 200, first servo motor 315 and second servo motor 327 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
