[0035] 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.

[0036] This invention provides a cultivation device for citrus planting, such as... Figure 1-17 As shown, the citrus cultivation equipment includes: a base plate 1 and an open frame 2. The open frame 2 is located directly above the base plate 1, and the distance between the two is adjustable. A heat-insulating bag 3 is fixedly installed between the base plate 1 and the open frame 2, and the inside is used for citrus seedling cultivation. Multiple mounting seats 4 are fixedly installed around the periphery of the base plate 1, and multiple ear blocks 6 are fixedly installed around the periphery of the open frame 2. The multiple ear blocks 6 are respectively positioned corresponding to the positions of the multiple mounting seats 4. A smooth shaft 5 is rotatably installed on each of the multiple mounting seats 4, and a lifting screw 7 is threadedly installed on each of the multiple ear blocks 6. The bottom ends of the multiple lifting screws 7 are respectively fixedly connected to the top ends of the multiple smooth shafts 5, so that the multiple smooth shafts 5 synchronously drive the multiple lifting screws 6. When the screw 7 rotates, it drives the opening frame 2 to rise and fall, so that the heat preservation bag 3 can be stretched or folded. Each of the multiple bare shafts 5 is fixedly fitted with a pulley 8, and the same synchronous belt 9 is fitted on the multiple pulleys 8. A motor 10 is connected to the bottom end of one of the bare shafts 5 to provide power. Multiple support legs 11 are fixedly installed on the top of the base plate 1. The same cup-placement plate 12 is fixedly installed on the top of the multiple support legs 11. The cup-placement plate 12 has placement holes for placing cultivation cups 13. The cultivation cups 13 are filled with cultivation soil and citrus cultivation branches are buried inside. A sealing plate 14 is slidably installed on the opening frame 2 to close the opening frame 2 when the heat preservation bag 3 is stretched, so as to keep the inside warm and moist.

[0037] In this embodiment, during use, the cultivation cups 13 containing potting soil and citrus branches are first placed into the placement holes of the cup plate 12. Then, the motor 10 is started, and the synchronous belt 9 drives all the pulleys 8, causing each shaft 5 to rotate synchronously, which in turn drives the lifting screw 7 fixed to it to rotate. The ear block 6 is threadedly engaged with the lifting screw 7, causing the open frame 2 to rise relative to the base plate 1. The heat preservation bag 3 then unfolds to form a sealed cavity. Subsequently, the sliding sealing plate 14 closes the open frame 2, realizing one-time batch heat preservation and water preservation cultivation. When observation or management is required, the motor 10 is driven in reverse, the open frame 2 descends, the sealing plate 14 opens synchronously, the heat preservation bag 3 folds, and the internal space shrinks, so that the cultivation cups 13 can be viewed or removed as a whole without having to remove the bags one by one.

[0038] This solution achieves synchronous movement of multiple lifting points through the linkage of motor 10, synchronous belt 9, pulley 8, smooth shaft 5, and lifting screw 7, ensuring the smooth lifting and lowering of the open frame 2 and preventing damage to the insulation bag 3 due to uneven stress. The insulation bag 3 can be stretched into a sealed greenhouse or folded for storage as it is lifted and lowered. With the sealing plate 14, it not only ensures the insulation and moisture retention of a large number of citrus cuttings, but also allows for one-time opening and closing during the inspection stage, significantly reducing the labor intensity of manual bag removal and improving management efficiency.

[0039] In a further preferred embodiment of the present invention, there are two sealing plates 14, each with an opening and closing rack 15. Mounting bases 16 are fixedly installed on both sides of the top of the opening frame 2. A drive shaft 17 and a driven shaft 18 are rotatably mounted on each of the two mounting bases 16. A drive gear 19 is fixedly sleeved on the drive shaft 17. Support plates 57 are fixedly installed on both sides of the base plate 1. Support columns 20 are fixedly installed on each of the two support plates 57. A fixed top is fixedly installed on the top of each of the two support columns 20. The racks 21 are respectively meshed with the two drive gears 19 so that the drive gears 19 roll along the racks 21 when the opening frame 2 is raised and lowered. Differential gear disks 22 are also fixedly sleeved on the two drive shafts 17. Differential gears 23 and opening / closing gears 24 are fixedly sleeved on the driven shaft 18. The differential gears 23 mesh with the differential gear disks 22 so that the drive shaft 17 drives the driven shaft 18 to rotate. The opening / closing gears 24 mesh with the opening / closing racks 15 so that the sealing plate 14 slides open and closes when the driven shaft 18 rotates.

[0040] In this embodiment, when the opening frame 2 is raised and lowered, the mounting bases 16 fixed on both sides of it move accordingly; the fixed rack 21 and the support column 20 remain stationary, the driving gear 19 rolls along the fixed rack 21 and drives the driving shaft 17 to rotate; the differential gear 22 rotates synchronously, and after being accelerated by the differential gear 23, it drives the driven shaft 18, so that the opening and closing gear 24 drives the opening and closing rack 15, realizing the automatic opposite sliding of the two sealing plates 14; when the opening frame 2 rises, the sealing plates 14 close and seal; when it falls, the sealing plates 14 slide open in the opposite direction, and the whole process does not require additional power or manual operation.

[0041] This solution utilizes the lifting stroke of the opening frame 2 as the sole power source. Through multi-stage transmission via a fixed rack 21, a drive gear 19, a differential gear 22, a differential gear 23, an opening and closing gear 24, and an opening and closing rack 15, the lifting motion is converted into the synchronous opening and closing of the sealing plate 14, eliminating the need for an independent drive device and manual intervention. The speed-increasing effect of the differential gear 23 ensures that the sealing plate 14 can quickly complete the opening and closing within a short stroke, avoiding interference with the cultivation cup 13 and the citrus branches.

[0042] In a further preferred embodiment of the present invention, a raised block 25 is fixedly installed at the bottom of the base plate 1, and a water tank 26 is fixedly installed at the bottom of the raised block 25. A water pump 27 is provided in the water tank 26, and a pump pipe 28 is installed at the drain end of the water pump 27. The pump pipe 28 extends through the water tank 26 and the base plate 1 to the side of the cup-holding plate 12. A water distribution pipe 29 is fixedly installed on the side of the cup-holding plate 12. The water distribution pipe 29 is connected to the pump pipe 28. A rigid water pipe 30 located above the cup-holding plate 12 is fixedly installed on the pump pipe 28. The rigid water pipe 30 is staggered from the cultivation cups 13. Multiple drip irrigation hoses 31 are fixedly installed on the rigid water pipe 30. The multiple drip irrigation hoses 31 extend to the corresponding cultivation cups 13 and are staggered from the citrus branches.

[0043] In this embodiment, the water pump 27 delivers water from the water tank 26 to the water distribution pipe 29 on the side of the cup plate 12 via the pump pipe 28, and then into the rigid water pipe 30; multiple drip irrigation hoses 31 are led out from the rigid water pipe 30, extending to the top of each cultivation cup 13 and avoiding the citrus branches to achieve fixed-point micro-drip irrigation; the shim block 25 raises the base plate 1, leaving installation space for the water tank 26 and facilitating the pipeline layout.

[0044] This solution utilizes a closed pipeline consisting of a water tank 26, a water pump 27, a pump pipe 28, a distribution pipe 29, a rigid water pipe 30, and a drip irrigation hose 31 to achieve undisturbed and uniform water replenishment within the closed cavity; the drip irrigation hose 31 is staggered to precisely wet the soil without impacting the branches.

[0045] In a further preferred embodiment of the present invention, the drip irrigation hose 31 is a telescopic universal hose, and the bottom of the drip irrigation hose 31 is provided with a drip irrigation hole for drip irrigation into the culture cup 13.

[0046] In this embodiment, the drip irrigation hose 31 is a telescopic universal hose that can be extended and bent in any direction. The operator adjusts the ends of each universal hose to the top of the cup opening and keeps them offset from the branches according to the actual position of the cultivation cup 13 and the citrus branches, and then locks the bending angle. After the water flows through the drip irrigation hose 31, it seeps out evenly from the drip irrigation hole at the bottom to achieve precise drip irrigation of the substrate in a single cup.

[0047] The universal telescopic structure of this solution allows the drip irrigation hose 31 to be positioned arbitrarily in three-dimensional space, adapting to cultivation cups 13 of different heights and plant spacing, ensuring that the drip irrigation hole is always located at the optimal drip point; the drip irrigation hole is located at the bottom of the pipe, so that the water droplets fall directly onto the soil surface, avoiding erosion of branches and substrate; the pipe body maintains its shape after bending, without the need for additional fasteners, simplifying assembly and reducing maintenance costs.

[0048] In a further preferred embodiment of the present invention, the rigid water pipe 30 has multiple sections arranged according to the arrangement of the multiple culture cups 13, and the end of the rigid water pipe 30 has a threaded section that is threadedly connected to the water distribution pipe 29.

[0049] In this embodiment, a corresponding number of rigid water pipes 30 are selected according to the number of cultivation cups 13; the threaded sections at the ends of each rigid water pipe 30 are screwed into the corresponding threaded interfaces of the water distribution pipe 29 to form a parallel multi-branch structure; each rigid water pipe 30 independently carries a row of drip irrigation hoses 31 to achieve precise water supply in separate rows.

[0050] The threaded connection allows for quick disassembly and addition / removal of the rigid water pipe 30, adapting to different batches and row spacing seedling layouts; multiple parallel water supply lines ensure balanced pressure in each row and consistent drip irrigation volume; the removed rigid water pipe 30 is easy to rinse and disinfect, preventing pipe blockage and bacterial residue.

[0051] In a further preferred embodiment of the present invention, sliding openings are provided on both opposite sides of the opening frame 2, and the sealing plate 14 and the opening and closing rack 15 slide through the sliding openings.

[0052] In this embodiment, the prefabricated sliding openings on both sides of the opening frame 2 provide a through-type slide rail for the sealing plate 14 and the opening and closing rack 15; when the opening frame 2 is raised and lowered, the opening and closing rack 15 slides horizontally in the sliding opening, driving the sealing plate 14 to extend or retract synchronously, thus completing the opening and closing action of the cavity.

[0053] In a further preferred embodiment of the present invention, the length ratio of the lifting screw 7 and the fixed rack 21 is 1:5 to 9, so that the sealing plate 14 preferentially closes or opens with the running stroke of the opening frame 2.

[0054] In this embodiment, the length ratio of the lifting screw 7 to the fixed rack 21 is set to 1:5 to 9. When the motor 10 drives the lifting screw 7 to raise or lower the opening frame 2, the relatively long stroke of the fixed rack 21 is amplified and output through the drive gear 19, differential gear 22, differential gear 23, and opening and closing gear 24, so that the sealing plate 14 is fully opened in advance during the process of the opening frame 2 completing its descent, thereby realizing "stroke priority" control.

[0055] This length ratio decouples the opening and closing action of the sealing plate 14 from the stretching / folding stroke of the insulation bag 3, ensuring that the cavity is completely sealed when the opening frame 2 reaches its limit position; when descending in the reverse direction, the sealing plate 14 also opens in advance to avoid interference with the incubation cup 13, thereby improving operational safety and overall cycle efficiency.

[0056] In a further preferred embodiment of the present invention, the two opening and closing gears 24 are respectively located on both sides of the opening frame 2, and the lengths of the two sealing plates 14 are both greater than half of the opening frame 2.

[0057] In this embodiment, two opening and closing gears 24 are respectively located on the left and right sides of the opening frame 2, each driving the corresponding sealing plate 14. Since the length of the sealing plate 14 is greater than half of the opening frame 2, the two plates overlap in the middle when sliding towards each other, achieving gapless closure and avoiding separation. When sliding in the opposite direction, they completely retract to both sides of the frame.

[0058] In a further preferred embodiment of the present invention, the rotational speed ratio between the drive gear 19 and the opening / closing gear 24 is 1:6 to 10, and the opening size of the opening frame 2 is larger than the size of the cup plate 12.

[0059] In this embodiment, the drive gear 19 and the opening / closing gear 24 mesh and transmit power at a speed ratio of 1:6 to 10. When the opening frame 2 is raised or lowered, the drive gear 19 rotates at low speed and drives the opening / closing gear 24 to rotate at high speed after being amplified by a high reduction ratio, so that the sealing plate 14 can quickly close or open. The opening size of the opening frame 2 is larger than that of the cup plate 12 to ensure operating space.

[0060] In a further preferred embodiment of the present invention, a water supply pipe 55 and a waste discharge pipe 56 are installed on one side of the water tank 26. Both the water supply pipe 55 and the waste discharge pipe 56 are equipped with valves, and a plug is provided at the funnel of the water supply pipe 55.

[0061] In this embodiment, the side wall of the water tank 26 is equipped with a water supply pipe 55 and a waste discharge pipe 56, both of which are equipped with valves. When replenishing water, the valve of the water supply pipe 55 is opened, and clean water enters the water tank 26 through a funnel with a plug. After filling, the valve is closed and the funnel is sealed with a plug. When it is necessary to change the water or clean, the valve of the waste discharge pipe 56 is opened to completely drain the water.

[0062] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments:

[0063] In another embodiment of the present invention, a water receiving trough 32 is provided on the top of the base plate 1. The size of the water receiving trough 32 is larger than the distribution range of the multiple culture cups 13. A drain hole 34 communicating with the water receiving trough 32 is fixedly installed on the bottom of the base plate 1. A valve is provided on the drain hole 34. The bottom of the culture cup 13 is provided with a drain hole 34 for draining excess water into the water receiving trough 32.

[0064] In this embodiment, the water receiving trough 32 at the top of the base plate 1 covers the entire arrangement area of ​​the culture cups 13; the drainage hole 34 at the bottom of each culture cup 13 guides excess water into the water receiving trough 32, and the accumulated water is discharged through the drainage hole 34 at the bottom of the base plate 1 and the valve.

[0065] The water collection trough 32 collects overflow from multiple cups at once, preventing water from soaking the roots; the centralized drainage hole 34 is equipped with a valve to achieve controlled discharge, avoiding frequent bag opening for cleaning; the overall cavity is kept clean, reducing the risk of disease and improving the stability of batch seedling production.

[0066] In another embodiment of the present invention, a track groove 35 is provided on the top of the cup-holding plate 12, and a track bar 36 is slidably installed in the track groove 35. A plurality of horizontal plates 37 are fixedly installed on the top of the track bar 36. The sliding trajectory of the plurality of horizontal plates 37 is located below the rigid water pipe 30. The track bar 36 drives the horizontal plates 37 to slide between two adjacent culture cups 13. A plurality of cup-pressing strips 38 are fixedly installed on the same side of the plurality of horizontal plates 37. When the cup-pressing strips 38 slide, they press against or detach from the plate. At the top of the corresponding culture cup 13, a hose support frame 39 is fixedly installed on the cup-pressing strip 38. The hose support frame 39 is fixedly sleeved on the drip irrigation hose 31 so that the drip irrigation hose 31 and the cup-pressing strip 38 can move and extend synchronously with the movement of the horizontal plate 37. The sliding of the horizontal plate 37 is synchronized with the lifting and lowering of the opening frame 2 and the sliding of the sealing plate 14. That is, when the opening frame 2 descends, the sealing plate 14 opens, and the horizontal plate 37 drives the cup-pressing strip 38 to detach from the culture cup 13. The drip irrigation hose 31 then retracts and detaches from the culture cup 13.

[0067] In this embodiment, the track groove 35 is opened on the top of the cup plate 12, and the track bar 36 slides along it; multiple horizontal plates 37 are fixed on the track bar 36, and their sliding trajectory is located below the rigid water pipe 30 and passes between adjacent culture cups 13; the cup pressing bar 38 is fixed on the same side of the horizontal plate 37, and can press or loosen the top of the culture cup 13 as the horizontal plate 37 slides; the hose support frame 39 is fixed to the cup pressing bar 38 and clamps the drip irrigation hose 31, so that the drip irrigation hose 31 and the cup pressing bar 38 extend and retract synchronously; when the opening frame 2 descends and the sealing plate 14 opens, the track bar 36 is driven backward by linkage, the cup pressing bar 38 is lifted away from the cup mouth, and the drip irrigation hose 31 retracts synchronously and detaches from the culture cup 13; conversely, when it rises, it resets and presses and extends. At this time, the drip irrigation hose 31 is an ordinary hose with a hard section at the end.

[0068] The pressure strip 38 presses the cup mouth tightly during the seedling stage to prevent the cultivation cup 13 from shifting due to equipment vibration; during the observation or transplanting stage, it automatically loosens as the opening frame 2 descends, avoiding manual removal of the fixation one by one; the hose support frame 39 ensures that the drip irrigation hose 31 and the pressure strip 38 extend and retract along the same trajectory, and the overall linkage reduces manual intervention, improving the efficiency of batch operation and the safety of operation.

[0069] In another embodiment of the present invention, a first bearing seat 40 is fixedly installed on the top of the cup-holding plate 12, and a transverse sliding screw 41 is rotatably installed on the first bearing seat 40. The transverse sliding screw 41 is threaded through multiple horizontal plates 37 so that when the transverse sliding screw 41 rotates, it drives the horizontal plates 37 and the track bar 36 to slide synchronously. A second bearing seat 42 is fixedly installed on the side of the first bearing seat 40, and a short shaft 43 is rotatably installed on the second bearing seat 42. A turning gear 44 is fixedly sleeved on the short shaft 43. A fixing strip is fixedly installed on the opening frame 2. 45. The fixing bar 45 is located below the opening and closing rack 15. A toggle rack 46 is fixedly installed on the fixing bar 45. The toggle rack 46 is the same length as the fixed rack 21 so that when the opening frame 2 drives the toggle rack 46 to a designated position, it meshes with the toggle gear 44, thereby driving the short shaft 43 to rotate. Both the short shaft 43 and the transverse screw 41 are fixedly fitted with pulleys 47. The two pulleys 47 are fitted with the same synchronous belt 48 so that the short shaft 43 drives the transverse screw 41 to rotate.

[0070] In this embodiment, when the opening frame 2 is raised and lowered, the fixing bar 45 fixed on it moves synchronously. When the actuating rack 46 reaches the shaft seat 42 with the frame, it meshes with the actuating gear 44, driving the short shaft 43 to rotate. The short shaft 43 drives the transverse screw 41 to rotate through the pulley 47 and the synchronous belt 48. The transverse screw 41 drives the horizontal plate 37 and the track bar 36 to slide synchronously along the track groove 35, so as to realize the pressing or releasing of the cup bar 38 on the cultivation cup 13, and keep the timing consistent with the opening and closing of the sealing plate 14.

[0071] Using the lifting stroke of the opening frame 2 as the sole power source, the movement of the opening frame 2 is converted into the precise lateral movement of the horizontal plate 37 through the transmission chain of the rack 46, the gear 44, the synchronous belt 48, and the transverse screw 41; the meshing trigger ensures that the action is synchronized with the sealing plate 14, avoiding mechanical interference; the overall structure is compact, easy to maintain, significantly reduces energy consumption and improves the automation level of mass seedling cultivation.

[0072] In another embodiment of the present invention, a bearing seat 49 is fixedly installed on the top of the base plate 1, and a bidirectional screw 50 is rotatably installed on the bearing seat 49. A pusher plate 51 is sleeved on both threaded sections of the bidirectional screw 50. Both pusher plates 51 are slidably located in the water receiving groove 32. When the bidirectional screw 50 rotates, it drives the pusher plates 51 to push water to the drain pipe 33. A differential pulley 52 is fixedly sleeved on the transverse screw 41, and a differential pulley 53 is fixedly sleeved on the bidirectional screw 50. A differential synchronous belt 54 is sleeved on the differential pulley 52 and the differential pulley 53 so that the bidirectional screw 50 and the transverse screw 41 rotate synchronously.

[0073] In this embodiment, when the transverse screw 41 rotates, it drives the differential pulley 53 through the differential belt 52 and the differential synchronous belt 54, so that the bidirectional screw 50 rotates synchronously; the two reverse threads of the bidirectional screw 50 drive the two pusher plates 51 to slide towards or away from each other in the water receiving tank 32, so as to concentrate the accumulated water and push it towards the drain pipe 33 and discharge it.

[0074] Using the existing power of the transverse screw 41, the water tank 32 is automatically cleaned via differential transmission, without the need for an additional motor; the bidirectional push plate 51 reciprocates to scrape and clean thoroughly, preventing residue accumulation and bacterial growth.

[0075] In summary, compared with related technologies, this device uses an insulated bag 3 that can be stretched into a sealed greenhouse or folded for storage as it is raised and lowered, in conjunction with a sealing plate 14. This ensures the insulation and moisture retention of a large number of citrus cuttings, and allows for a one-time opening and closing of the entire device during the inspection phase, significantly reducing the labor intensity of manual bag removal and improving management efficiency.
