Description

Technical Field

[0001] This invention relates to the field of spirea cultivation technology, and more particularly to a cultivation device for spirea cultivation. Background Technology

[0002] Spirea, a common ornamental plant, requires high levels of environmental control and ease of management during its seedling stage. Currently, Spirea cultivation largely relies on traditional flat seedling racks or simple multi-layer racks, which are difficult to adapt to the needs of large-scale, refined cultivation.

[0003] Flat seedling racks for spirea take up too much space, which is not conducive to large-scale seedling cultivation. In contrast, existing multi-layer seedling racks for spirea have fixed positions for each layer of seedlings, and the upper layers can easily cause severe light shading of the lower layers, resulting in uneven growth of spirea seedlings. Furthermore, the seedling trays located on the upper layers are inconvenient to access, and sprinkler irrigation is also quite troublesome.

[0004] Therefore, it is necessary to provide a cultivation device for planting Spiraea japonica to solve the above-mentioned technical problems. Summary of the Invention

[0013] Preferably, the cultivation rack is also equipped with a spray assembly for spraying fertilizer or water onto the seedling trays. The spray assembly includes: a second base fixed to one side of any unit frame, on which a water pump is fixedly installed, with the inlet and outlet of the water pump connected to a pumping pipe and an outlet pipe, respectively; and a horizontal mounting pipe fixedly installed on the two uppermost vertical rods and arranged horizontally, with multiple rows of nozzles fixedly installed on the horizontal mounting pipe for spraying multiple seedling trays on the uppermost trough.

[0018] Compared with related technologies, the cultivation device for planting Spiraea japonica provided by the present invention has the following beneficial effects: The cultivation rack is composed of trapezoidal unit frames with a narrow upper layer and a wide lower layer layout to reduce light shading. Combined with multi-layered height-adjustable seedling units, it ensures uniform light exposure for spirea on each layer, improving the uniformity of seedling growth. The trapezoidal frame is fixed with vertical and horizontal bars to form a stable structure, which greatly increases the number of seedling layers in the same space, significantly improving space utilization and making it suitable for large-scale cultivation. The horizontal shaft is driven by a servo motor, which synchronously drives the gear sets and drive sprockets on both sides to move, so as to raise or lower the multi-layer seedling unit. Operators can adjust the seedling unit to a suitable height according to their needs, which improves the efficiency of seedling tray loading and maintenance operations by % and significantly reduces labor intensity. The seedling unit uses a mesh-plate trough to support the seedling trays, and excess water and fertilizer drips off through the mesh plate; the groove on the lid of the liquid storage tank and the drain outlet enable efficient water and fertilizer recovery, and the filter cartridge filters impurities to prevent nozzle clogging, forming a closed loop of "spraying-recovery-reuse", which improves the utilization rate of water and fertilizer and reduces water and fertilizer waste. The triggering mechanism can automatically start the water pump when the seedling unit moves directly under the nozzle to carry out the spraying operation, thereby realizing automated spraying and achieving complete coverage of the seedling tray by the spray surface; By linking the driving mechanisms of the stirring component and the lifting component, the water and fertilizer in the storage tank can be stirred without adding a motor, thus promoting the dissolution of granular fertilizer.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This invention provides a cultivation device for planting Spiraea japonica, such as... Figure 1-20 As shown, the cultivation device for planting spirea includes: a cultivation frame 1, which consists of two identical unit frames 10 and a plurality of crossbars 103 fixed between the two unit frames 10; a multi-layer seedling unit for spirea seedling cultivation located between the two unit frames 10, and each of the two unit frames 10 is equipped with a lifting component for supporting the seedling unit and driving the seedling unit to rise and fall.

[0024] In this embodiment, when the cultivation device for planting spirea is in use, the lifting components on the cultivation rack 1 can drive the multi-layer seedling units to rise and fall smoothly. The operator can adjust each layer of seedling units to a suitable height to facilitate the placement and removal of the seedling trays 34 and to carry out maintenance work.

[0025] In a further preferred embodiment of the present invention, the unit frame 10 is trapezoidal (e.g., Figure 20 As shown), the unit frame 10 consists of two vertical rods 101 and a plurality of horizontal rods 103 fixed between the two vertical rods 101. The two ends of the horizontal rods 103 are respectively fixedly connected to the two opposite vertical rods 101 in the two unit frames 10.

[0026] In this embodiment, the trapezoidal unit frame 10 uses two vertical rods 101 as the main support structure, and together with multiple horizontal rods 103 fixed between them, forms a stable frame. The two ends of the horizontal rods 103 are fixedly connected to the opposite vertical rods 101 in the two unit frames 10, so that the two independent unit frames 10 are combined into a complete cultivation rack 1. In use, the cultivation rack 1 provides a reliable installation foundation for multi-layer seedling units and lifting components. The trapezoidal structure of the unit frame 10 features a layout that is narrower at the top and wider at the bottom, effectively reducing the light shading of the lower layers by the upper seedling units, ensuring that each layer of spirea seedlings receives sufficient light, and improving... The uniform growth and the stable connection between the vertical bar 101 and the horizontal bar 103 give the cultivation rack 1 excellent wind resistance and load-bearing capacity. It can stably support the weight of multiple seedling units and seedling trays 34, avoiding shaking or structural deformation during use. This structural design ensures cultivation stability while allowing the cultivation rack 1 to have more seedling layers in the same space, improving space utilization and adapting to the needs of large-scale spirea cultivation. It also provides solid structural support for the subsequent lifting components to drive the seedling units to rise and fall smoothly and for the spraying components to operate precisely, indirectly improving the ease of operation and cultivation reliability of the entire device.

[0027] In a further preferred embodiment of the present invention, (e.g.) Figure 10 , 16 As shown in Figure 18, the seedling unit includes a trough 33, on which multiple seedling trays 34 are placed. Tripods 32 are fixedly installed at both ends of the trough 33. The tripods 32 are equipped with fixed shafts 31 set on the lifting assembly. The tripods 32 are rotatably mounted on the fixed shafts 31 through bearings.

[0028] In this embodiment, the seedling unit uses the trough 33 as the core supporting structure. Multiple seedling trays 34 are placed directly inside the trough 33 to achieve centralized cultivation of spirea seedlings. The tripods 32 fixed at both ends of the trough 33 are rotatably mounted on the fixed shaft 31 of the lifting component through bearings. When in use, they work with the lifting component to drive the fixed shaft 31 to rise and fall, which can adjust the seedling unit to a suitable height for easy access and maintenance of the seedling trays 34. The structural design of the tripods 32 enhances the stability of the connection between the trough 33 and the lifting component, ensuring that the trough 33 and the seedling trays 34 remain stable during the raising and lowering of the seedling unit, preventing the spirea seedlings from tipping over or the seedling trays 34 from shifting.

[0029] In a further preferred embodiment of the present invention, the bottom inner wall of the tank 33 is a mesh structure (e.g., Figure 17 As shown), multiple seedling trays 34 are placed on the bottom inner wall of the trough 33 and are adapted to fit the trough 33 (e.g. Figure 18 As shown in the figure, the placement slot of the trough 33 in this scheme can just accommodate four seedling trays 34.

[0030] In this embodiment, the trough 33 with a mesh-like structure on the bottom inner wall provides a stable placement space for the seedling trays 34. The four seedling trays 34 are adapted to the trough 33 and fit perfectly within it, enabling the centralized and orderly cultivation of spirea seedlings. When in use, the water and fertilizer sprayed by the spray component can penetrate the seedling trays 34 and be absorbed by the spirea. Excess water and fertilizer will drip naturally through the mesh-like bottom of the trough 33, avoiding water accumulation in the trough 33 that could cause root rot in the seedlings. At the same time, the dripping water and fertilizer can be recycled and reused by the liquid storage tank 48 below. The mesh structure not only ensures the breathability of the bottom of the seedling trays 34, but also provides key support for the construction of the water and fertilizer circulation system.

[0031] In a further preferred embodiment of the present invention, (e.g.) Figure 7 , 8 The lifting assembly (as shown in Figures 9 and 10) includes: multiple first rotating shafts 11 mounted on the unit frame 10, the first rotating shafts 11 being rotatably mounted on the vertical rod 101 via bearings, and support sprockets 12 being fixedly sleeved on the first rotating shafts 11; a main chain 13 meshing with the multiple support sprockets 12, and a fixed shaft 31 fixed to one side of the main chain 13; a fixed plate 14 fixed to the top of one of the vertical rods 102 of the unit frame 10, and a second rotating shaft 15 being rotatably mounted on the fixed plate 14 via bearings; and a drive sprocket 16 fixedly sleeved on the second rotating shaft 15, the drive sprocket 16 meshing with the main chain 13 and used to drive the movement of the main chain 13 to realize the lifting and lowering of the multi-layer seedling unit; wherein, each lifting assembly is equipped with a drive mechanism for driving two drive sprockets 16 in the two lifting assemblies to rotate, thereby driving the movement of the main chain 13 and realizing the lifting and lowering of the multi-layer seedling unit.

[0032] In this embodiment, when the lifting assembly is working, the drive mechanism synchronously drives the drive sprockets 16 on the two unit frames 10 to rotate. The first rotating shaft 11, fixed on the vertical rod 101 of the unit frame 10, stably supports the support sprocket 12 on it through bearings. The main chain 13 is engaged between the support sprocket 12 and the drive sprocket 16. When the drive sprocket 16 rotates, it drives the main chain 13 to move smoothly along the support sprocket 12. The fixed shaft 31 of the seedling unit is fixed on one side of the main chain 13. The movement of the main chain 13 drives the multi-layer seedling unit to rise or fall. During use, the operator can control the seedling unit to rise to a height that is convenient for picking up and placing the seedling tray 34 through the drive mechanism, or adjust the seedling unit so that each seedling unit has the opportunity to be on the top layer. This structure ensures that all seedling units receive adequate sunlight. Multiple support sprockets 12 provide multi-point support to the main chain 13, and the precise drive of the drive sprockets 16 ensures stable movement of the main chain 13, preventing tilting or jamming during seedling unit lifting. Two lifting components share a single drive mechanism for synchronized operation, solving the problem of asynchronous lifting at both ends of the seedling unit. This keeps each layer of seedling units horizontal, preventing the seedling trays 34 within the trough 33 from shifting or tipping over. This improves operational convenience during spirea cultivation, reduces the labor intensity of handling the upper seedling trays 34, and ensures stability during seedling unit movement, providing a safe growing environment for spirea seedlings.

[0033] In a further preferred embodiment of the present invention, (e.g.) Figure 3 , 5 The drive mechanism (as shown in Figure 13) includes: a horizontal long shaft 17 rotatably mounted on two fixed plates 14 via two bearings, with a second gear 19 fixedly sleeved at both ends of the horizontal long shaft 17; two first gears 18 fixedly sleeved on two second rotating shafts 15 respectively, with the two first gears 18 meshing with the two second gears 19 respectively; and a first base 20 fixedly mounted on one side of any one of the fixed plates 14, with a servo motor 21 fixedly mounted on the first base 20, the output shaft of the servo motor 21 being fixedly connected to one end of the horizontal long shaft 17 via a coupling.

[0034] In this embodiment, when the drive mechanism is working, the servo motor 21 fixed on the first base 20 starts, and its output shaft drives the horizontal shaft 17 to rotate smoothly around the bearings on the two fixed plates 14 through the coupling. The second gears 19 at both ends of the horizontal shaft 17 rotate synchronously. Since the two second gears 19 mesh with the first gears 18 on the two second rotating shafts 15 respectively, the two second rotating shafts 15 are driven to rotate synchronously, so that the drive sprocket 16 in the lifting assembly obtains power and drives the main chain 13 to move, and finally realizes the lifting or lowering of the multi-layer seedling unit. When in use, the operator can precisely control the lifting height and speed of the seedling unit by controlling the servo motor 21 through the electrical control cabinet.

[0035] In a further preferred embodiment of the present invention, (e.g.) Figure 9 , 12 As shown, two third rotating shafts 22 are rotatably mounted on the fixed plate 14 via bearings. Each of the two third rotating shafts 22 is fixedly fitted with a guide sprocket 23 that meshes with the main chain 13. The two guide sprockets 23 are located on both sides of the drive sprocket 16, respectively, to improve the wrapping between the main chain 13 and the drive sprocket 16, so that the main chain 13 can be effectively driven to move when the drive sprocket 16 rotates.

[0036] In this embodiment, two third rotating shafts 22 mounted on the fixed plate 14 via bearings provide stable support for the guide sprockets 23, so that the two guide sprockets 23 are respectively located on both sides of the drive sprocket 16 and mesh with the main chain 13. In use, the guide sprockets 23 can move and rotate synchronously with the main chain 13. By fitting against both sides of the main chain 13, they increase the wrapping degree between the main chain 13 and the drive sprocket 16, preventing the main chain 13 from slipping or disengaging when the drive sprocket 16 rotates. This ensures that the power of the drive sprocket 16 can be efficiently transmitted to the main chain 13 to drive the seedling unit to rise and fall smoothly. This design ensures that the main chain 13 always maintains reliable meshing with the drive sprocket 16 during movement, improving the stability and safety of the lifting component, and thus ensuring the stability of the seedling trays 34 and the spirea seedlings in the tank 33.

[0037] In a further preferred embodiment of the present invention, (e.g.) Figure 1 , 2 As shown in Figure 4, the cultivation rack 1 is also equipped with a spraying assembly for spraying water and fertilizer or water onto the seedling trays 34. The spraying assembly includes: a second base 41 fixed on one side of any unit rack 10, on which a water pump 42 is fixedly installed. The inlet and outlet of the water pump 42 are respectively connected to a pumping pipe 46 and an outlet pipe 43; and a horizontal mounting pipe 44 fixedly installed on the two uppermost vertical rods 102 and arranged horizontally. Multiple rows of nozzles 45 are fixedly installed on the horizontal mounting pipe 44 for spraying multiple seedling trays 34 on the uppermost trough 33.

[0038] In this embodiment, the spray assembly on the cultivation rack 1 provides a stable mounting base for the water pump 42 through the second base 41. When in use, after the water pump 42 is started, it draws water fertilizer or water through the water pipe 46, and then delivers it through the water outlet pipe 43 to the horizontally mounted horizontal pipe 44 fixed on the two uppermost vertical rods 102. The water fertilizer or water is evenly sprayed by the multiple rows of nozzles 45 on the mounted horizontal pipe 44 into the multiple seedling trays 34 on the corresponding uppermost tank 33, so as to achieve precise water and fertilizer supply for the spirea seedlings. The horizontal layout of the mounted horizontal pipe 44, together with the multiple rows of nozzles 45, can achieve full coverage spraying of the seedling trays 34, avoiding uneven nutrition or water for the seedlings caused by missed spraying.

[0039] In a further preferred embodiment of the present invention, (e.g.) Figure 1, 2 As shown in Figure 7, a liquid storage tank 48 is fixedly installed on the two horizontal bars 103 at the bottom layer. One end of the water pumping pipe 46 extends into the liquid storage tank 48 and is equipped with a filter cartridge 47 to prevent particulate impurities in the water and fertilizer from entering the water pumping pipe 46 and clogging the nozzle 45.

[0040] In this embodiment, the liquid storage tank 48 is fixedly installed on the two bottommost crossbars 103 to provide storage space for fertilizer or water. When in use, the water pump 42 draws liquid from the liquid storage tank 48 through the water pumping pipe 46. The filter cartridge 47 installed at the end of the water pumping pipe 46 can filter the liquid, effectively intercepting particulate impurities in the fertilizer and preventing them from entering the water pumping pipe 46, the water outlet pipe 43 and the nozzle 45 and causing blockage, thus ensuring the continuous and stable operation of the spraying assembly. The installation position of the liquid storage tank 48 utilizes the lower space of the cultivation rack 1, without occupying additional seedling area, thus improving space utilization efficiency.

[0041] In a further preferred embodiment of the present invention, (e.g.) Figure 19 As shown, the top opening of the liquid storage tank 48 is provided with a tank cover 49. The top of the tank cover 49 is recessed into a groove, and a drain outlet is provided on the groove for collecting the liquid dripping from the bottom of the tank 33 and flowing into the liquid storage tank 48.

[0042] In this embodiment, the lid 49 at the top of the liquid storage tank 48 has a recessed groove structure to receive excess liquid dripping from the bottom of the mesh plate of the tank 33. The liquid flows precisely into the liquid storage tank 48 through the drain on the groove to complete the recycling. The drain ensures that the received liquid flows into the liquid storage tank 48 efficiently. Together with the filter cartridge 47 on the water pumping pipe 46, water and fertilizer filtration and recycling are realized, and a complete cycle of "spraying-dripping-recycling-reuse" is constructed, which greatly improves the utilization rate of water and fertilizer. At the same time, the covering effect of the lid 49 on the liquid storage tank 48 can also reduce liquid evaporation.

[0043] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In yet another embodiment of the present invention, (e.g.) Figure 8 , 11(As shown in Figure 15) A triggering mechanism is installed on one side of one of the vertical rods 101, which can trigger the water pump 42 to start and perform spraying operation when any tank 33 moves to directly below the nozzle 45. Abutment blocks 51 are installed at equal intervals on one side of one of the main chains 13 to cooperate with the triggering mechanism. The triggering mechanism includes: a mounting box 52 fixedly installed on one side of the vertical rod 101, with a lifting block 53 disposed inside the mounting box 52; a sliding rod 54 fixedly installed at the bottom of the lifting block 53 and vertically arranged, the bottom end of the sliding rod 54 extending below the mounting box 52 and slidably connected to the mounting box 52; and a force-bearing block 55 fixedly installed at the bottom end of the sliding rod 54. Ball bearings are embedded in the bottom of the force block 55 and the top of the abutment block 51; a spring 56 is slidably sleeved on the slide rod 54, the spring 56 being located at the top of the force block 55 and the bottom of the mounting box 52; two lifting conductive blocks 57 are fixedly installed on the top of the two lifting blocks 53 and two fixed conductive blocks 58 are fixed on the inner wall of the top of the mounting box 52, the two lifting conductive blocks 57 being located directly below the two fixed conductive blocks 58; wherein, two insulating telescopic sleeves 59 are installed between the top of the lifting block 53 and the inner wall of the top of the mounting box 52, the two lifting conductive blocks 57 being located inside the two insulating telescopic sleeves 59, and the two fixed conductive blocks 58 being located inside the two insulating telescopic sleeves 59.

[0044] In this embodiment, the mounting box 52 on one side of the vertical rod 101 provides a mounting base for the components of the triggering mechanism. When the lifting assembly drives the main chain 13 to move, the abutments 51 installed at equal intervals on one side of the main chain 13 move synchronously with it. When a certain abutment 51 moves to below the force block 55, the ball bearing at the top of the abutment 51 contacts the ball bearing at the bottom of the force block 55 and pushes the force block 55 to rise. The force block 55 drives the slide rod 54 to slide upward along the mounting box 52, the spring 56 is compressed, and the lifting block 53 at the top of the slide rod 54 rises accordingly, so that the lifting conductive block 57 at the top of the lifting block 53 contacts the fixed conductive block 58 on the inner wall of the top of the mounting box 52, triggering the water pump 42 to start. At this time, the groove 3 corresponding to the abutment 51... 3. When the nozzle 45 is positioned directly below the spray assembly, the spray assembly can precisely spray the seedling trays 34 in the tank 33. After spraying, the stop block 51 continues to move with the main chain 13, the thrust on the force block 55 disappears, the spring 56 resets, and the force block 55, slide bar 54 and lifting block 53 descend. The lifting conductive block 57 separates from the fixed conductive block 58, the water pump 42 stops working, and the insulating telescopic sleeve 59 installed between the lifting block 53 and the mounting box 52 can prevent water or fertilizer from entering the conductive block area and causing a short circuit. This design realizes the precise linkage between the tank 33 and the spraying operation, and can complete the automated spraying of each layer of seedling units without manual control, avoiding missed spraying or accidental spraying, and improving spraying efficiency and accuracy.

[0045] It should be noted that, in addition to the "switch" formed by the triggering component, the water pump 42 is also equipped with a main switch. Only when the main switch is turned on can the triggering component trigger the water pump 42 to turn on and off. When the main switch is turned off, the water pump 42 is always in the off state and is not affected by the triggering component.

[0046] In yet another embodiment of the present invention, (e.g.) Figure 2 , 5 As shown in Figures 6 and 7, a stirring assembly is installed on the storage tank 48 to stir the undissolved granular fertilizer and water in the storage tank 48, so that the granular fertilizer dissolves. The stirring assembly includes: multiple stirring shafts 61 rotatably mounted on the inner walls of both sides of the storage tank 48 via sealed bearings; multiple stirring rods 62 are fixedly mounted on each of the multiple stirring shafts 61; and the same end of each of the multiple stirring shafts 61 extends to the outside of the storage tank 48 and is fixedly fitted with two transmission pulleys 63. The transmission pulleys 63 on two adjacent stirring shafts 61 are connected by a first belt 64; and two main pulleys 65 are fixedly fitted on the output shaft of the servo motor 21 and one end of any stirring shaft 61, and the two main pulleys 65 are connected by a second belt 66.

[0047] In this embodiment, the stirring assembly on the storage tank 48 achieves stable rotation through multiple stirring shafts 61 mounted on sealed bearings. When the servo motor 21 of the drive mechanism starts, the main pulley 65 on its output shaft drives the main pulley 65 at one end of any stirring shaft 61 to rotate via the second belt 66. The stirring shaft 61 rotates accordingly, and the transmission pulley 63 at its end drives the transmission pulley 63 on the adjacent stirring shaft 61 to rotate via the first belt 64, so that multiple stirring shafts 61 operate synchronously. The stirring rod 62 on the stirring shaft 61 fully stirs the undissolved granular fertilizer and water in the storage tank 48, accelerating the dissolution of the granular fertilizer to form a uniform liquid fertilizer. No additional drive motor is required during use; the stirring function can be achieved with the power of the servo motor 21, reducing energy consumption and manufacturing costs. The cooperation of multiple stirring shafts 61 and stirring rods 62 ensures no dead corners in the stirring, avoiding uneven water and fertilizer concentration caused by the deposition of granular fertilizer. This ensures balanced water and fertilizer nutrition for the spirea seedlings sprayed into the seedling tray 34, improving the cultivation quality. At the same time, uniform water and fertilizer also reduces the probability of clogging of the filter cartridge 47 and nozzle 45, reducing the frequency of device maintenance. This stirring design linked with the lifting drive system makes the entire cultivation device more integrated and efficient in operation, providing a stable and reliable water and fertilizer supply guarantee for the large-scale cultivation of spirea.

[0048] It is worth noting that the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve improvements to the software and methods. This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.

[0049] In summary, compared with related technologies, this solution solves the problems of uneven lighting and inconvenient operation in the cultivation of Spiraea japonica. The cultivation rack 1, composed of trapezoidal unit frames 10, reduces light shading, and, in conjunction with the synchronous lifting component, ensures uniform seedling growth and improves space utilization. The linkage system driven by the servo motor 21 enables smooth lifting and lowering of the seedling units, reducing the difficulty of high-level operation and improving work efficiency. The mesh trough 33, the liquid storage tank 48, and the filter cartridge 47 establish a water and fertilizer circulation system, improving utilization. The triggering mechanism, linked with the spraying component, achieves precise liquid supply, and the stirring component ensures uniform water and fertilizer distribution.
