Description

Technical Field

[0001] This invention relates to the field of plant cultivation rack technology, specifically a height-adjusting and telescopic device for plant cultivation racks. Background Technology

[0002] Plant cultivation racks are devices specifically designed for plant growth. Through multi-layered structures and environmental control systems, they optimize space utilization and provide suitable growing conditions, and are widely used in scientific research, agricultural production, and home gardening.

[0003] Currently, most existing plant cultivation racks adopt a fixed structure design. Not only is the height and position of each cultivation layer fixed, but the light source arranged on it is also a fixed design. During the plant cultivation process, different varieties of plants and different growth cycles have different environmental requirements, especially the requirements for light intensity. Therefore, the adaptability of the fixed structure cultivation rack is limited. Although some plant cultivation racks can adjust the position of the light source, they are mostly independent structures. Their arrangement in the cultivation layer not only occupies the height of the planting space, but the individual height adjustment of the light source configured on each layer further increases the production cost of the cultivation rack. The individual adjustment during operation is also relatively troublesome, increasing the workload of the staff. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides an integrated lifting and telescopic adjustment device for plant cultivation racks. By setting a drive mechanism to adjust the height of each cultivation layer in the rack, and with each switching component moving synchronously during the operation of the drive mechanism, the light sources in each cultivation layer can be automatically and synchronously adjusted, avoiding the inconvenience of manual adjustment of existing light sources, reducing the workload. Furthermore, by combining existing light sources with the support mechanism, the configuration structure is optimized, reducing the space occupied in planting and lowering the manufacturing cost of the equipment. Each switching component can be flexibly adjusted, allowing the light source in each cultivation layer to be independently adjusted, further ensuring the adaptability of the equipment and solving the problems mentioned in the background art.

[0023] 2. The combination of light source and support mechanism optimizes its configuration structure, reduces the occupation of planting space, lowers the manufacturing cost of the equipment, and allows each switching component to be flexibly adjusted. Furthermore, the light source in each cultivation layer can be independently extended and retracted, further ensuring the adaptability of the equipment.

[0024] 3. Each substrate tray in the cultivation layer can be individually raised and lowered by the corresponding pushing mechanism to meet the cultivation needs of plants with different cultivation requirements in individual planting spaces on the same cultivation rack.

[0025] 4. When the light source in the support mechanism is extended or retracted, the cleaning component is driven to move synchronously, thereby cleaning the top of each lamp in the light source, reducing the amount of dust adhering to it, ensuring the heat dissipation and light efficiency of each lamp in the light source, and extending its service life.

[0038] Please see Figures 1-2 In this embodiment of the invention, a plant cultivation rack with integrated lifting and telescopic adjustment device includes a cultivation rack composed of multiple support members 1, and a cultivation layer disposed on the cultivation rack. The cultivation layer also includes multiple layers, which are linearly distributed longitudinally on the cultivation rack. The three-dimensional cultivation of plants is realized through the arrangement of each cultivation layer.

[0039] The cultivation layer includes a support mechanism 2 set on the cultivation rack. A substrate tray 3 for cultivating plants is placed on the top of the support mechanism 2. A pushing mechanism 4 for adjusting the height of the substrate tray 3 is installed at the bottom of the support mechanism 2. The pushing mechanism 4 can adjust the height of the substrate tray 3 over a short distance, improving the adaptability of the equipment.

[0040] The space between two adjacent support mechanisms 2 is a planting space for plant growth. The cultivation rack is also equipped with adjustment components for adjusting the support mechanism 2. The adjustment components include scissor-type parts 5 and drive mechanism 6. There are multiple scissor-type parts 5, which are arranged in pairs and located on both sides of the support mechanism 2, and are used to connect the two adjacent support mechanisms 2. The drive mechanism 6 is used to drive the height adjustment of the support mechanism 2.

[0041] When the drive mechanism 6 is running, it adjusts the scissor pieces 5 on the bottom support mechanism 2, thereby adjusting the height of the upper cultivation layer. With the cooperation of each scissor piece 5, the adjustment of each cultivation layer is realized, and due to the setting of the scissor pieces 5, the adjustment height between each cultivation layer is consistent.

[0042] Please see Figures 2-4 and Figure 10In this embodiment of the invention, the driving mechanism 6 includes a base plate 61, a motor 62, a rotating shaft 63, a worm gear 64, a switching component 65, a bidirectional lead screw 66, a toothed chain 67, a worm wheel 68, and a pushing plate assembly 69. The base plate 61 is disposed on the cultivation rack, the motor 62 is mounted on the base plate 61, the rotating shaft 63 is disposed on the output end of the motor 62, the worm gear 64 is fixedly connected to the bottom end of the rotating shaft 63, and the switching component 65 includes multiple components that are linearly distributed longitudinally on the rotating shaft 63, and the switching component 65 corresponds one-to-one with the support mechanism 2.

[0043] Multiple guide bars are provided on the outer ring of the rotating shaft 63 along the circumferential direction. The switching component 65 is slidably connected to the rotating shaft 63, so that when the motor 62 is running, it drives the rotating shaft 63 to rotate, thereby synchronously driving the various switching components 65 and the worm gear 64 to move.

[0044] Since the switching component 65 is slidably connected on the rotating shaft 63, the switching component 65 slides synchronously on the rotating shaft 63 when the height of each culture layer is adjusted.

[0045] There are two bidirectional lead screws 66, which are symmetrically arranged in the cultivation rack. The two bidirectional lead screws 66 are linked by a toothed chain 67 to ensure that the two bidirectional lead screws 66 move synchronously.

[0046] The worm gear 68 is mounted on the left-side double-acting lead screw 66, and the worm gear 68 meshes with the worm 64 for transmission. The push plate assembly 69 includes two parts, which are movably connected to the corresponding double-acting lead screw 66, and the push plate assembly 69 is connected to the corresponding support mechanism 2.

[0047] When the worm 64 moves, it drives the double-acting lead screw 66 on the left side through the worm wheel 68. Under the action of the toothed chain 67, the two double-acting lead screws 66 move synchronously, thereby causing the push plate assembly 69 on them to move. In this way, with the cooperation of the scissor piece 5, the height of each cultivation layer can be adjusted.

[0048] Please see Figures 2-3 In this embodiment of the invention, the support member 1 includes four members arranged in a matrix, and the support member 1 is composed of an L-shaped rod 11 and a pad 12, wherein the pad 12 is integrally disposed on the inner wall of the L-shaped rod 11.

[0049] The pad 12 is used to support the bottom layer of the culture layer, thereby improving the stability of the culture layer on the culture rack.

[0050] Please see Figure 2 and Figures 5-9In this embodiment of the invention, the support mechanism 2 includes a frame 21, a pad 22, guide members 23 and a lighting component 24. The pad 22 is integrally disposed on the inner shell wall of the frame 21 and is used to support the substrate tray 3. There are four guide members 23, which are respectively disposed at the four corners of the frame 21. The four guide members 23 are disposed to adapt to the corresponding support members 1, thereby ensuring the stability of the movement of the culture layer.

[0051] The guide component 23 includes an L-shaped plate 231 that is fixedly connected to the outside of the corner of the frame 21 by bolts. A guide plate 232 is installed on the L-shaped plate 231 by fastening bolts. The guide plate 232 is slidably connected to the L-shaped rod 11. The bottom guide plate 232 not only contacts the corresponding pad 12, but is also fixedly connected to the L-shaped rod 11 by bolts, thereby locking the position of the bottom cultivation layer.

[0052] The lighting assembly 24 includes a slide rail 241, a light source, a reciprocating screw 244, a sliding frame 245, and a cleaning assembly. The slide rail 241 includes two slide rails, which are symmetrically arranged on the bottom shell wall of the pad 22. The light source is movably connected to the symmetrical slide rails 241. The reciprocating screw 244 is located above the light source, and both ends of the reciprocating screw 244 pass through the corresponding side walls of the pad 22 and the frame 21, respectively. An adjustment handle is installed on the right end of the reciprocating screw 244.

[0053] The adjustment handle allows for manual adjustment of the reciprocating lead screw 244 in the lighting assembly 24;

[0054] The light source includes lamps 242 and traction belts 243. The lamps 242 include multiple lamps, which are laterally linearly distributed below two slide rails 241 and are movably connected to the slide rails 241.

[0055] The lamp 242 includes a lamp body and a base. There are two bases, which are respectively disposed at the front and rear ends of the lamp body. The two bases are slidably connected to the corresponding slide rails 241, thereby ensuring the ease of adjustment of the lamp 242.

[0056] The traction belt 243 also includes multiple belts, arranged in pairs and symmetrically distributed front and back. The two adjacent lamps 242 are connected by the traction belt 243. The two rightmost traction belts 243 are fixed to the corresponding inner wall of the frame 21 by screws at the ends away from the corresponding lamps 242.

[0057] When the traction belt 243 is connected to the lamp 242, its end is fixedly connected to the corresponding carrier by rivets. The rightmost lamp 242 is connected to the frame 21 by the traction belt 243 configured on it, which ensures the stability of each lamp 242 after it is spread out.

[0058] Limit blocks are installed on the right ends of both slide rails 241 by bolts to ensure the neatness of the arrangement of each lamp 242 on the slide rail 241 after it is retracted, so as to facilitate subsequent unfolding operations.

[0059] When there are few plants in the substrate tray 3 in the planting space, arrange these plants on the right side of the substrate tray 3, and then close the lamps 242 in the corresponding lighting components 24. The external controller can reduce the light intensity of each lamp 242 in the cultivation layer, thereby reducing energy consumption while ensuring the light needs of these plants.

[0060] The sliding bracket 245 is movably connected to the reciprocating lead screw 244, and both ends of the sliding bracket 245 are connected to the two seats of the leftmost lamp 242. There are various ways to connect the sliding brackets 245, and in this embodiment, screw connection is used.

[0061] The cleaning assembly includes a cleaning brush 246 and an adjustment plate 247. There are two cleaning brushes 246, which are symmetrically distributed above the lamp 242. The two ends of the cleaning brushes 246 are slidably connected to the corresponding inner walls of the frame 21.

[0062] The inner walls on both sides of the frame 21 are provided with sliding grooves, and two sliders are slidably connected in the sliding grooves. The cleaning brush 246 is composed of a brush and a round rod. There are two round rods, which are located on both sides of the brush. The end of the round rod away from the brush is fixedly connected to the corresponding slider.

[0063] A movable block is threaded onto the reciprocating screw 244, and two adjusting plates 247 are also included, which are respectively movably connected to the top of the corresponding cleaning brush 246 by pins, and the ends of the two adjusting plates 247 away from the corresponding cleaning brush 246 are respectively movably connected to the movable block by pins.

[0064] The reciprocating lead screw 244 has two sets of reciprocating threads, one set for adjusting the moving block and the other set for adjusting the sliding frame 245;

[0065] When the reciprocating screw 244 moves, the moving block on it moves accordingly. Due to the connection between the two adjusting plates 247 and the corresponding cleaning brushes 246, there is a restraining force on the moving block. When the reciprocating screw 244 moves, the moving block on it moves linearly. The adjusting plates 247 cause the two cleaning brushes 246 to move accordingly, thereby cleaning the dust and other substances attached to the top of each lamp 242.

[0066] The pushing mechanism 4 includes an electric push rod 41, a frame plate 42, and a pushing rod 43. There are two electric push rods 41, which are symmetrically arranged on the bottom sides of the pad plate 22. The frame plate 42 is fixedly connected to the output ends of the two electric push rods 41. There are four pushing rods 43, which are respectively arranged at the top four corners of the frame plate 42, and the top of the pushing rod 43 passes through the corresponding pad plate 22.

[0067] The substrate tray 3 has slots at the four corners of its bottom. These slots correspond to the push rods 43. When the electric push rod 41 moves the frame plate 42 upward, the push rods 43 on it move accordingly. The top of the push rod 43 extends into the corresponding slot, thereby improving the stability of pushing the substrate tray 3 upward.

[0068] The outer walls on both sides of the frame 21 are integrally provided with slide bar groups. Each slide bar group has two slide sleeves symmetrically connected in the front and back. Each slide sleeve has a protruding rod welded to its outer wall.

[0069] The scissor-type component 5 includes a support rod and a center pin. There are two support rods, which are staggered and movably connected by the center pin. Each support rod is movably connected to a corresponding protruding rod.

[0070] Please see Figures 2-4 and Figures 8-11 In this embodiment of the invention, the base plate 61 is fixedly connected to the top of the two support members 1 on the left by bolts, and a bracket is rotatably connected above the worm gear 64 by a bearing. The bracket is connected to the bottom support mechanism 2.

[0071] The stability of the rotating shaft 63 and the worm gear 64 is ensured by the configuration of the base plate 61 and the bracket.

[0072] The front and rear ends of the two bidirectional lead screws 66 are rotatably connected to the inner wall of the corresponding L-shaped rod 11 via bearings. The push plate assembly 69 is composed of two push plates, each of which is threadedly connected to the corresponding bidirectional lead screw 66, and the top of the push plate is fixedly connected to the corresponding sliding sleeve at the bottom layer by screws.

[0073] When the bidirectional lead screw 66 rotates, the push plates threaded onto it move accordingly, thereby driving the displacement adjustment of the sliding sleeve in the bottom support mechanism 2.

[0074] The switching component 65 includes a sleeve 651 that is slidably connected to the rotating shaft 63. A splicing plate is rotatably connected to the outer shell wall of the sleeve 651 via a bearing. The right side of the splicing plate is fixedly connected to the corresponding frame 21 by bolts.

[0075] When each cultivation layer is raised or lowered, the corresponding switching component 65 is adjusted in height on the rotating shaft 63 via the splicing plate;

[0076] Below the splicing plate is a main bevel gear 652 located on the outer shell wall of the sleeve 651. Above the main bevel gear 652 is a driven bevel gear 653 that meshes with it. The main bevel gear 652 is larger than the driven bevel gear 653, thus forming a deceleration motion between it and the driven bevel gear 653. This, in conjunction with the worm gear 64 and the worm wheel 68, ensures the consistency of the height adjustment between the lighting component 24 and the cultivation layer.

[0077] A sleeve 654 is installed on the side wall of the bevel gear 653. A drive shaft is slidably connected inside the sleeve 654. The sliding connection between the sleeve 654 and the drive shaft allows the sleeve 654 to drive the drive shaft to rotate synchronously when it rotates, and ensures the sleeve 654 can extend and retract on the drive shaft to meet the needs of adjustment.

[0078] The right end of the drive shaft is connected to the corresponding reciprocating lead screw 244 via a coupling 655. A straight plate 656 is rotatably connected to the outer ring shell wall of the sleeve 654 via a bearing. The top of the straight plate 656 is slidably connected to the corresponding splicing plate. A threaded rod 657 is rotatably connected to the side wall of the splicing plate via a bearing.

[0079] The straight plate 656 has a hole, and an inner threaded ring is installed in the hole. The inner threaded ring is threadedly connected to the threaded rod 657.

[0080] By adjusting the threaded rod 657, the threaded plate 656 connected to it is linearly displaced, thereby driving the sleeve 654 to slide on the transmission shaft, causing the corresponding bevel gear 653 to move and disengage from the corresponding main bevel gear 652, making it convenient to adjust the lighting component 24 in the cultivation layer individually.

[0081] The topmost cultivation layer only needs to provide light to the plants in the next cultivation layer, so there is no need to configure a substrate tray 3 and a pushing mechanism 4 on it. A cover plate 7 for covering is bolted to it. The cover plate 7 is connected to the frame 21 to ensure the lighting effect of the lighting component 24 on the plants in the next cultivation layer.

[0082] There are no plants to be cultivated below the bottommost cultivation layer, so there is no need to configure the lighting component 24, and the switching component 65 in the drive mechanism 6 does not need to consider the bottommost cultivation layer when setting it up.

[0083] The working principle of this invention is as follows: When the product is used, the plants to be cultivated are first placed in the substrate trays 3 in each cultivation layer. Then, the lighting components 24 in the support mechanism 2 in each cultivation layer need to be pre-adjusted so that the lamps 242 on them are evenly distributed.

[0084] The motor 62 in the drive mechanism 6 is started by the external controller. The operation of the motor 62 drives the rotating shaft 63 to rotate. At this time, the worm 64 and its multiple switching components 65 that are in contact with the rotating shaft 63 move synchronously. The worm 64 meshes with the worm wheel 68 to drive the corresponding bidirectional lead screw 66 to rotate. When the bidirectional lead screw 66 moves, it causes another bidirectional lead screw 66 to move synchronously through the toothed chain 67. When the bidirectional lead screw 66 rotates, the push plate group 69 connected to it moves, thereby causing the bottom sliding sleeve to move. The scissor piece 5 drives the height adjustment of each corresponding cultivation layer.

[0085] Since it is necessary to adjust the position of the corresponding lamps 242 in each lighting component 24 first, and then each switching component 65 adjusts the height of the corresponding cultivation layer, the sleeve 651 in the switching component 65 moves on the rotating shaft 63, and the rotating shaft 63 rotates synchronously, driving the sleeve 651 to rotate.

[0086] During the rotation of the sleeve 651, the main bevel gear 652 on it rotates, and the main bevel gear 652 meshes with the corresponding driven bevel gear 653 to drive the corresponding sleeve 654 to move. Then, through the transmission shaft and coupling 655, the reciprocating screw 244 of the lighting component 24 in the support mechanism 2 in the corresponding cultivation layer is driven to rotate.

[0087] During the rotation of the reciprocating screw 244, the sliding frame 245 and the moving block on it move. When the sliding frame 245 moves, it pulls the leftmost lamp 242 to the left. As the leftmost lamp 242 moves, the traction belt 243 on it pulls and adjusts the other lamps 242.

[0088] When the moving block moves, it drives the two cleaning brushes 246 to move through the adjusting plate 247, thereby cleaning the top of each lamp 242.

[0089] When each cultivation layer rises to its highest position, the lights 242 of the lighting components 24 in the support mechanism 2 of each cultivation layer are fully deployed and evenly distributed. At this time, the program in the external controller body shuts down the motor 62. Then, the staff manually rotates and adjusts the threaded rod 657 in each switching component 65. When the threaded rod 657 moves, the straight plate 656 threaded to it drives the sleeve 654 to move to the right. At this time, the sleeve 654 retracts linearly on the corresponding transmission shaft, so that the bevel gear 653 disengages from the corresponding main bevel gear 652.

[0090] According to the number of plants to be cultivated in each substrate tray 3, the corresponding lighting components 24 are adjusted. If the substrate tray 3 is basically full of plants to be cultivated, then there is no need to adjust the corresponding lighting components 24. If there are few plants to be cultivated in the substrate tray 3, arrange these plants on the right side of the substrate tray 3, and then adjust the corresponding lighting components 24.

[0091] At this time, when adjusting the corresponding lighting component 24, the corresponding reciprocating screw 244 is moved by operating the adjustment handle. Since the bevel gears 653 and the corresponding main bevel gears 652 are disengaged at this time, only the lighting component 24 in the individual cultivation layer is adjusted. When the reciprocating screw 244 moves, the sliding frame 245 and the moving block on it move accordingly, thereby adjusting each lamp 242 and the cleaning brush 246. When manually adjusting the adjustment handle, it is necessary to observe the movement state of each lamp 242. When it is retracted to a suitable state, stop operating the adjustment handle.

[0092] After adjusting the lighting components 24 in the support mechanism 2 of each cultivation layer, the planting space between each cultivation layer needs to be adjusted according to the type and growth stage of the object to be cultivated. At this time, since each switching component 65 has been disengaged after adjustment, when the external controller body restarts the motor 62, the rotating shaft 63 drives the worm gear 64 to move, which in turn causes the push plate group 69 in the two bidirectional screws 66 to move, and the scissor piece 5 realizes the approximate adjustment of the planting space in each cultivation layer.

[0093] If a local adjustment is required, the electric push rod 41 of the corresponding pushing mechanism 4 in the corresponding cultivation layer is activated by the external controller, which drives the frame plate 42 to move. In this way, the corresponding pushing rod 43 on the frame plate pushes the corresponding substrate tray 3 to move, thereby achieving environmental adjustment for plant cultivation.

[0094] 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.
