Description

Technical Field

[0001] This invention relates to the field of seedling supplemental lighting technology, and more particularly to an intelligent supplemental lighting device for vegetable greenhouse seedling cultivation. Background Technology

[0002] In the current seedling stage of greenhouse vegetables, insufficient sunlight or rainy weather often leads to uneven light exposure and weak stems in the seedlings.

[0003] Existing greenhouse supplemental lighting mostly uses fixed installation, resulting in a relatively singular illumination direction. When the lights need maintenance or replacement, the fixed connection structure also increases the disassembly and assembly time.

[0004] In this situation, a swing-type supplementary lighting structure is usually used to expand the coverage of the supplementary lighting. However, when the swing component is switching back and forth for a long time, the reliability of the driving structure and the stability of the lamp holder connection must also be taken into account.

[0005] Furthermore, when using mechanical contact to suppress seedling etiolation, if only a pressing component is provided without a straightening and yielding structure to match the pressing stroke, the seedling is prone to bending or lodging during the pressing process. However, if independent drive mechanisms are used to control pressing and straightening, the number of drive components will increase and the timing of the two actions will become more complex.

[0006] Therefore, it is necessary to provide a vegetable greenhouse seedling cultivation device that can utilize the same reciprocating power to establish the timing sequence of uprighting, pressing down, and automatic retraction and reset, while also taking into account swing supplemental lighting and rapid maintenance of lamps. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent supplemental lighting cultivation device for vegetable greenhouse seedlings, in order to solve the problems of unstable coordination between the straightening action and the pressing stroke during mechanical seedling pressing, as well as the single illumination direction of the supplemental light and the inconvenience of maintenance and disassembly.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A smart supplemental lighting cultivation device for vegetable greenhouse seedlings includes a greenhouse, a first mounting beam, a second mounting beam, and a cultivation frame set inside the greenhouse. The greenhouse is equipped with a supplemental lighting component for providing additional light to the seedlings. The greenhouse is also equipped with a seedling pressing and straightening component, which includes a straightening frame, a straightening roller, a first limiting groove plate, a third slider, a third spring, a slide rail, a first electric push rod, a fourth slider, a connecting rod, a second limiting groove plate, a fifth slider, a sliding rod, a pressing block, a wedge block, a limiting rod, a slider box, a fourth spring, a second electric push rod, a seedling pressing frame, a seedling pressing roller, and a mounting shaft.

[0010] The slide rail is installed on the side wall of the greenhouse, the fourth slider is slidably connected to the slide rail, the telescopic end of the first electric push rod is connected to the fourth slider; the second electric push rod is installed below the fourth slider, its telescopic end is connected to the seedling pressing frame, the two ends of the mounting shaft are fixed to the two sides of the seedling pressing frame, and the seedling pressing roller is rotated and sleeved on the mounting shaft.

[0011] The second limiting groove plate is installed on the side wall of the greenhouse. The fifth slider is slidably disposed in the second limiting groove plate and fixedly connected to the slide rod. The two ends of the connecting rod are respectively hinged to the fourth slider and the upper end of the slide rod. A third slider is slidably disposed in the first limiting groove plate. A third spring is disposed between the third slider and the bottom wall of the first limiting groove plate. The straightening frame is fixedly connected to the third slider. Several straightening rollers are rotatably disposed on the straightening frame.

[0012] The slider box is fixed to the side wall of the straightening frame, the wedge block is fixedly connected to the limiting rod, the limiting rod passes through the slider box and is slidably connected to the slider box, the fourth spring is set between the wedge block and the slider box, the lower end of the sliding rod is provided with a wedge end that cooperates with the wedge block, and the pressing block is set at the end of the movement path of the wedge block.

[0013] When the first electric push rod drives the fourth slider to reciprocate, the pressing roller moves along the top of the cultivation frame with the fourth slider. At the same time, the fourth slider drives the sliding rod to move via the connecting rod. The wedge end of the sliding rod drives the straightening frame to move along the first limiting groove plate through the wedge block. When the wedge block moves to the pressing block, it overcomes the elastic force of the fourth spring and retracts into the slider box, so that the straightening frame is reset under the action of the third spring.

[0014] Preferably, the straightening frame is arranged around the outer periphery of the cultivation frame, and a number of straightening rollers are arranged at intervals along the straightening frame. The pressing roller is located above the cultivation frame, and the second electric push rod is used to adjust the working height of the pressing roller relative to the cultivation frame.

[0015] Preferably, both the first limiting groove plate and the second limiting groove plate are arranged vertically, and the first electric push rod serves as a common reciprocating power source for the horizontal operation of the pressing roller and the lifting action of the straightening frame, so that the straightening action of the straightening frame is coordinated with the pressing stroke of the pressing roller.

[0016] Preferably, the seedling pressing and straightening component is provided in six sets, and is respectively arranged opposite to the corresponding cultivation frame.

[0017] Preferably, the supplementary lighting assembly includes a rotating plate, a lamp holder, a supplementary light, and a driving mechanism for driving the rotating plate to swing back and forth. The two ends of the rotating plate are respectively rotatably mounted on a first mounting beam and a second mounting beam. The lamp holder is located below the rotating plate, and the supplementary light is mounted below the lamp holder.

[0018] Preferably, the drive mechanism includes a motor, a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, a synchronous belt, two sets of missing gears, two sets of gears, a spiral spring, and a rotating rod. The motor is mounted on the side of the first mounting beam, and the output shaft of the motor is fixedly connected to the first synchronous pulley. The second and third synchronous pulleys are coaxially connected to their corresponding missing gears. The first synchronous pulley is connected to the second and third synchronous pulleys via a synchronous belt drive.

[0019] Preferably, each set of missing gears intermittently meshes with the corresponding gear. One end of the rotating rod is fixedly connected to the rotating plate, and the other end is connected to one end of the spiral spring. The other end of the spiral spring is connected to the gear. When the missing gear meshes with the gear, it drives the rotating plate to swing to one side and causes the spiral spring to store energy. After the missing gear disengages from the gear, the spiral spring releases its elastic potential energy and drives the rotating plate to swing back.

[0020] Preferably, a quick-release assembly is provided between the rotating plate and the lamp holder. The quick-release assembly includes a first limiting groove, a first spring, a first slider, a mounting cavity, a second slider, a second spring, and a second limiting groove. The first limiting groove is disposed at both ends of the lamp holder, the first slider is slidably disposed in the first limiting groove, and the first spring is disposed between the first slider and the side wall of the first limiting groove.

[0021] Preferably, the mounting cavity is disposed on the rotating plate, the second limiting groove is disposed at both ends of the mounting cavity, the second slider is slidably disposed in the second limiting groove, and the second spring is disposed between the second slider and the side wall of the second limiting groove; after the lamp holder is inserted into the mounting cavity, the first slider and the second slider abut against each other to form an elastic snap-fit, and pressing the second slider can cause the first slider to retract into the first limiting groove to release the elastic snap-fit.

[0022] The present invention has the following beneficial effects:

[0023] 1. In this invention, the first electric push rod is used as a common reciprocating power source. The fourth slider drives the pressing roller to move along the upper part of the cultivation frame. At the same time, the connecting rod drives the sliding rod to move. The wedge end of the lower end of the sliding rod cooperates with the wedge block to drive the straightening frame to move. When the wedge block reaches the pressing block position, the wedge block retracts into the slider box, and the straightening frame automatically resets under the action of the third spring.

[0024] This creates a coordinated action of straightening constraint, pressing and rolling, and yielding and resetting within a single reciprocating drive, reducing the timing deviation when pressing and straightening are performed using independent reciprocating drives, and lowering the risk of seedlings continuously bending or lodging during the pressing process.

[0025] 2. After the lamp holder is inserted into the mounting cavity of the rotating plate, the first slider and the second slider form a double-sided elastic engagement under the action of the spring. During maintenance, pressing the second slider will cause the first slider to retract and release the engagement.

[0026] This structure facilitates disassembly and assembly while utilizing elastic pre-tightening to absorb the intermittent impacts generated when the supplementary light lamp swings back and forth with the rotating plate, reducing the possibility of the lamp holder loosening under long-term swinging conditions.

[0027] 3. The supplementary lighting component utilizes the intermittent meshing of the gears to periodically store energy in the spiral spring. After disengagement, the spiral spring drives the rotating plate to swing back, thereby obtaining the reciprocating oscillation of the supplementary light under unidirectional continuous drive conditions. This reduces the commutation control and impact burden caused by frequent forward and reverse rotation of the motor, expands the scanning irradiation range of the supplementary light, and improves the uniformity of light reception in the cultivation area.

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] Reference Figure 5 , Figure 6 , Figure 12 , Figure 13 A smart supplemental lighting cultivation device for vegetable greenhouse seedlings includes a greenhouse 1, a first mounting beam 2, a second mounting beam 3, and a cultivation frame 23. The greenhouse 1 is equipped with a supplemental lighting component and a seedling pressing and straightening component corresponding to the cultivation frame 23. The seedling pressing and straightening component provides lateral support to the seedlings during mechanical pressing and automatically retracts and resets after completing its corresponding stroke.

[0045] The seedling pressing and straightening assembly includes a straightening frame 24, straightening rollers 25, a first limiting groove plate 26, a third slider 27, a third spring 28, a slide rail 29, a first electric push rod 30, a fourth slider 31, a connecting rod 32, a second limiting groove plate 33, a fifth slider 34, a slide bar 35, a pressing block 36, a wedge block 37, a limiting rod 38, a slider box 39, a fourth spring 40, a second electric push rod 41, a seedling pressing frame 42, a seedling pressing roller 43, and a mounting shaft 44. The straightening frame 24 surrounds the outer periphery of the cultivation frame 23, and several straightening rollers 25 are rotatably mounted on the straightening frame 24; the seedling pressing roller 43 is located above the cultivation frame 23, and the seedling pressing roller 43 is rotatably mounted on the mounting shaft 44, the two ends of which are fixed to both sides of the seedling pressing frame 42.

[0046] The slide rail 29 is installed on the side wall of the greenhouse 1. The fourth slider 31 is slidably connected to the slide rail 29. The first electric push rod 30 is installed on one side of the slide rail 29, and its telescopic end is fixedly connected to the fourth slider 31. The second electric push rod 41 is installed below the fourth slider 31. The telescopic end of the second electric push rod 41 is connected to the seedling pressing frame 42. The working height of the seedling pressing roller 43 relative to the cultivation frame 23 can be adjusted by extending and retracting the second electric push rod 41.

[0047] The second limiting groove plate 33 is installed on the side wall of the greenhouse 1. The fifth slider 34 is slidably disposed within the second limiting groove plate 33 and is fixedly connected to the slide rod 35. One end of the connecting rod 32 is hinged to the fourth slider 31, and the other end is hinged to the upper end of the slide rod 35. When the first electric push rod 30 drives the fourth slider 31 to reciprocate, the fourth slider 31 drives the slide rod 35 to reciprocate under the constraint of the second limiting groove plate 33 via the connecting rod 32.

[0048] A third slider 27 is slidably disposed within the first limiting groove plate 26. A third spring 28 is provided between the third slider 27 and the bottom wall of the first limiting groove plate 26. The straightening frame 24 is fixedly connected to the third slider 27. The slider box 39 is fixed to the side wall of the straightening frame 24. The wedge block 37 is fixedly connected to the limiting rod 38. The limiting rod 38 passes through the slider box 39 and is slidably connected to the slider box 39. A fourth spring 40 is disposed between the wedge block 37 and the slider box 39. The lower end of the sliding rod 35 is provided with a wedge end that cooperates with the wedge block 37. The pressing block 36 is disposed at the end of the movement path of the wedge block 37. The seedling pressing and straightening assembly can be configured into six sets according to the arrangement of the cultivation frame 23.

[0049] In this embodiment, a plant height sensor can be installed below the pressing frame 42 to monitor the height of the seedlings in the cultivation frame 23 in real time. When the seedling height reaches the preset critical pressing height, the height of the pressing frame 42 is first adjusted by the second electric push rod 41 so that the pressing roller 43 is in a pressing position that matches the seedling crown. Then, the first electric push rod 30 is activated, and the fourth slider 31 moves back and forth along the slide rail 29. The pressing frame 42 and the pressing roller 43 move along the upper part of the cultivation frame 23 with the fourth slider 31. At the same time, the fourth slider 31 drives the slide rod 35 to move via the connecting rod 32. The wedge end of the lower end of the slide rod 35 engages with the wedge block 37, so that the wedge block 37 transmits the motion to the slider box 39 and the straightening frame 24 under the support of the fourth spring 40. The straightening frame 24 moves along the first limiting groove plate 26, so that the straightening roller 25 provides lateral support to the tilted seedlings when the pressing roller 43 passes through the corresponding area.

[0050] When the wedge block 37 moves to the pressing block 36, the pressing block 36 forces the wedge block 37 to retract into the slider box 39 against the elastic force of the fourth spring 40, thereby releasing the continuous drive of the wedge block 37 on the straightening frame 24. The straightening frame 24 then resets under the action of the third spring 28. Thus, one reciprocating stroke of the first electric push rod 30 enables the straightening action to form a defined mechanical coordination with the working stroke of the seedling pressing roller 43, and automatically retracts and resets at the end of the stroke, preventing the straightening frame 24 from continuously interfering with the seedlings during subsequent return strokes.

[0051] Example 2

[0052] Reference Figure 3 , Figure 4 , Figure 11 The quick-release assembly includes a first limiting groove 16, a first spring 17, a first slider 18, a mounting cavity 19, a second slider 20, a second spring 21, and a second limiting groove 22. The first limiting groove 16 is located at both ends of the lamp holder 5, the first slider 18 is slidably disposed within the first limiting groove 16, and the first spring 17 is provided between the first slider 18 and the side wall of the first limiting groove 16.

[0053] The mounting cavity 19 is disposed on the rotating plate 4, the second limiting groove 22 is disposed at both ends of the mounting cavity 19, the second slider 20 is slidably disposed in the second limiting groove 22, and a second spring 21 is provided between the second slider 20 and the side wall of the second limiting groove 22. After the lamp holder 5 is inserted into the mounting cavity 19, the first slider 18 and the second slider 20 abut against each other to form an elastic snap-fit.

[0054] In this embodiment, when installing the supplementary light 6, the supplementary light 6 along with the lamp holder 5 is inserted into the mounting cavity 19 of the rotating plate 4. The first slider 18 abuts against the second slider 20 under the action of the first spring 17, keeping the lamp holder 5 within the mounting cavity 19. When it is necessary to replace the supplementary light 6, the second slider 20 is pressed from both sides of the rotating plate 4, causing the second slider 20 to push the first slider 18 back into the first limiting groove 16. After releasing the latch between the lamp holder 5 and the mounting cavity 19, the lamp holder 5 and the supplementary light 6 can be removed.

[0055] The above-mentioned double-sided elastic snap-fit ​​structure can complete the installation and removal of the lamp holder 5 without repeatedly disassembling and assembling the threaded fasteners; when the supplementary light 6 swings back and forth with the rotating plate 4, the first spring 17 and the second spring 21 can also provide elastic pre-tightening and buffering for the snap-fit ​​position, so that the connection can adapt to the inertial impact generated by the reciprocating swing.

[0056] Example 3

[0057] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10The supplementary lighting assembly includes a rotating plate 4, a lamp holder 5, a supplementary light 6, and a driving mechanism. The two ends of the rotating plate 4 are respectively rotatably mounted on the first mounting beam 2 and the second mounting beam 3. The lamp holder 5 is located below the rotating plate 4, and the supplementary light 6 is mounted below the lamp holder 5.

[0058] The drive mechanism includes a motor 7, a first synchronous pulley 8, a second synchronous pulley 9, a third synchronous pulley 10, a synchronous belt 11, two sets of missing gears 12, two sets of gears 13, a spiral spring 14, and a rotating rod 15. The motor 7 is mounted on the side of the first mounting beam 2, and the output shaft of the motor 7 is fixedly connected to the first synchronous pulley 8; the second synchronous pulley 9 and the third synchronous pulley 10 are coaxially connected to their corresponding missing gears 12, and the first synchronous pulley 8 is connected to the second synchronous pulley 9 and the third synchronous pulley 10 by the synchronous belt 11.

[0059] Each missing gear 12 intermittently meshes with the corresponding gear 13, which is rotatably mounted on the side of the first mounting beam 2. One end of the rotating rod 15 is fixedly connected to the rotating plate 4, and the other end is connected to one end of the spiral spring 14. The other end of the spiral spring 14 is connected to the gear 13 and is located inside the gear 13.

[0060] In this embodiment, when the light sensor installed inside greenhouse 1 determines that the real-time light intensity inside greenhouse 1 is lower than the light threshold required for seedling growth, the control system automatically turns on the supplemental lighting 6 and starts the motor 7. The motor 7 drives two sets of missing gears 12 to rotate via the first synchronous pulley 8, synchronous belt 11, second synchronous pulley 9, and third synchronous pulley 10. When the missing gear 12 meshes with the corresponding gear 13, the gear 13 drives the rotating plate 4 to swing to one side through the spiral spring 14 and rotating rod 15. At the same time, the spiral spring 14 undergoes elastic deformation and stores energy. When the missing gear 12 rotates to the position where it disengages from the gear 13, the spiral spring 14 releases its elastic potential energy, causing the rotating rod 15 and rotating plate 4 to swing back. As the missing gear 12 rotates continuously, the above process is repeated periodically, causing the lamp holder 5 and the supplemental lighting 6 to swing back and forth with the rotating plate 4.

[0061] The intermittent energy storage swing structure composed of the missing gear 12 and the spiral spring 14 can make the fill light 6 swing back and forth by keeping the motor 7 in a single direction. It does not need to rely on the motor to frequently reverse to complete the return action, thus simplifying the reversing control and reducing the impact caused by frequent motor reversing. The reversing swing of the fill light 6 also expands the scanning illumination range of the lamp, which helps to reduce the local light difference caused by the fixed illumination direction.

[0062] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
