Description

Technical Field

[0001] This application relates to the field of tea tree cultivation technology, and in particular to a tea seedling raising device for tea tree cultivation. Background Technology

[0002] Tea trees are perennial evergreen economic crops belonging to the Camellia genus of the Theaceae family. Their tender leaves can be processed into tea. Tea seed propagation is a sexual reproduction method that relies on tea seeds to complete germplasm propagation. It is an important means of preserving the original characteristics of tea trees and cultivating seedlings in large quantities. Tea seed propagation is mostly carried out on seedbeds in constant temperature and humidity seedling sheds. Moreover, seedlings need to be shaded in the early stage of seedling cultivation to avoid the tender buds being scorched by strong sunlight.

[0003] Currently, existing seedbeds are often equipped with shading nets or other shading mechanisms to provide independent shading. However, in actual seedling cultivation, the light intensity requirements of conventional tea seedlings vary significantly at different growth stages: newly emerged seedlings require high-shading nets to reduce strong light and prevent scorching; mid-growth seedlings are suited to medium-shading nets for balanced light exposure; and older, robust seedlings require low-shading nets to improve photosynthetic efficiency and promote lignification. Existing shading mechanisms in seedbeds are mostly fixed nets with a single shading rate, which cannot adjust the shading level according to the seedling age to match corresponding light requirements. This easily leads to problems such as scorching of tender buds or weak seedling growth due to insufficient light, affecting the quality of tea seedling cultivation. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, one objective of this application is to provide a tea seedling raising device for tea tree cultivation, which, by setting up a multi-layer roll-up shading mechanism, allows for convenient adjustment of the shading level according to the light requirements of the tea seed germination stage and the seedling growth period, thereby ensuring the quality of tea tree seedling cultivation.

[0006] To achieve the above objectives, this application provides a tea seedling cultivation device, comprising a bed frame, a seedbed net, and a multi-layer roll-up shading mechanism. The seedbed net is disposed within the bed frame to support the tea seedling trays. The multi-layer roll-up shading mechanism is mounted on the bed frame and can switch between a rolled-up and an unfolded state. When the multi-layer roll-up shading mechanism is unfolded, it can provide shading to the seedling area within the bed frame. The multi-layer roll-up shading mechanism includes multiple guide rails, multiple shading nets with different shading rates, two side plates disposed on the bed frame, multiple sets of support components, and two automatic... The bed frame includes a traction mechanism and multiple sets of winding assemblies. The multiple sets of support assemblies are slidably mounted on the bed frame via corresponding guide rails.

Each set of support assemblies is connected to one end of a corresponding shade net, and the other ends of the multiple shade nets are wound around corresponding winding assemblies. The multiple sets of winding assemblies are equidistantly rotatable within two side plates in a vertical direction.

[0008] In one embodiment of this application, each winding assembly includes a winding shaft, two limiting sleeves, two springs, and two caps. The winding shaft is rotatably disposed within the two side plates, with both ends of the winding shaft extending outwards. The two springs are respectively sleeved on the outer sides of the two extended ends of the winding shaft, and the inner ends of the springs are fixed to the winding shaft. The two limiting sleeves are respectively fixedly disposed on the corresponding side plates and connected to the caps. The two springs are respectively located within the corresponding limiting sleeves, and the outer ends of the springs are connected to the corresponding limiting sleeves.

[0009] In one embodiment of this application, one end of the shade net is wound around the outer wall of the take-up shaft, and the other end of the shade net is connected to the support rod.

[0010] In one embodiment of this application, each of the automatic traction mechanisms includes a traction component and a connecting component. The traction component includes a drive member, a traction wheel, a traction belt, and a guide wheel. The drive member is disposed on the corresponding side plate, and the drive end of the drive member is connected to the traction wheel. The guide wheel is disposed on the bed frame, and the traction belt is sleeved on the outside of the guide wheel and the traction wheel to form a circular traction loop.

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] The following description, in conjunction with the accompanying drawings, describes a tea seedling cultivation device for tea tree cultivation according to an embodiment of this application.

[0019] The embodiment of this application provides a tea seedling cultivation device for tea tree cultivation, which can be applied to the cultivation of tea tree seedlings. It can flexibly adjust the shading level and adapt to the light requirements of different budding stages of tea seeds and different growth stages of seedlings.

[0020] like Figures 1-9As shown in the figure, a tea seedling raising device for tea tree cultivation according to an embodiment of this application includes a bed frame 1, a seedbed net 2 and a multi-layer roll-up shading mechanism, wherein the seedbed net 2 is set inside the bed frame 1 and is used to support the tea seedling trays.

[0021] It should be noted that the bottom of the bed frame 1 is equipped with a load-bearing crossbeam and a vertical load-bearing bracket, which can stably support the seedling tray. Moreover, the seedbed net 2 is woven from rust-proof steel wire mesh with uniform mesh size, which facilitates the rapid drainage of excess water during the seedling process, preventing water accumulation in the seedling substrate from causing tea seeds to rot and seedlings to rot. It also facilitates ventilation inside the seedbed.

[0022] The main body of the seedbed consists of the bed frame 1, the seedbed net 2, the horizontal load-bearing beams, and the vertical load-bearing supports. It can be placed in the seedling shed and provides a stable cultivation space for tea seedlings.

[0023] A multi-layer roll-up shading mechanism is installed on the bed frame 1. The multi-layer roll-up shading mechanism can switch between rolled-up and unfolded states. When the multi-layer roll-up shading mechanism is in the unfolded state, it can provide shading for the seedling area within the bed frame 1. The multi-layer roll-up shading mechanism includes multiple guide rails 3, multiple shading nets 4 with different shading rates, two side plates 5 installed on the bed frame 1, multiple sets of support components 6, two automatic traction mechanisms, and multiple sets of roll-up components 9. The multiple sets of support components 6 are slidably installed on the bed frame 1 through corresponding guide rails 3. The multiple sets of support components 6 are U-shaped frame structures. The length and width dimensions of each U-shaped frame structure gradually increase from the inside to the outside and are arranged sequentially from the inside to the outside.

[0024] Each set of support components 6 is connected to one end of the corresponding shade net 4. The other ends of multiple shade nets 4 are respectively wound around the corresponding winding components 9. Multiple sets of winding components 9 are equidistantly rotated in the vertical direction within the two side plates 5. Two automatic traction mechanisms are symmetrically arranged on the bed frame 1 to traction the corresponding support components 6 to move along the guide rail 3.

[0025] It should be noted that the number of shade nets 4 is preferably 3, corresponding to the three levels of shading requirements from the inside out: low (30% shading rate), medium (50% shading rate), and high (75% shading rate). Each shading rate corresponds to a stage of use and is a conventional technical method for tea farmers and the seedling industry. In actual use, the shading rate value can be adaptively adjusted according to the actual light conditions of the seedling shed in the region and the characteristics of the tea seed variety to further improve the adaptability of the device.

[0026] In practical applications, the seedling stage is 0-60 days after the tea seeds sprout from the soil. The seedlings only have small leaves and no fully formed true leaves. Using a 75% shading net can reduce the intensity of direct sunlight, prevent the tender buds from being scorched by strong light and causing wilting and necrosis, and ensure that the seedlings can successfully complete the transition from sprouting to growth. If the shading rate is insufficient or below 75% during the seedling stage, strong light will quickly remove the surface moisture of the tender buds, causing the tender bud tissue to be scorched and necrotic, reducing the survival rate of tea seed sprouting. During this stage, when shading, the net should be fully covered for shading from 9:00 to 17:00 on sunny days, and the net should be removed to allow light to pass through on cloudy days, in the early morning, evening, and at night to prevent excessive growth due to prolonged weak light.

[0027] During the mid-growth stage, 60 days after emergence, when seedlings have grown 2-3 complete true leaves and their resistance has slightly improved, a 50% shading net can be switched on. This ensures that while reducing strong light, the seedlings are provided with sufficient diffused light, balancing the needs of shading and photosynthesis. When shading, the shading net should only be deployed during the strong light period from 10:30 to 15:30 at midday, while allowing the seedlings to receive moderate natural light in the morning and evening, thus balancing photosynthesis and preventing scorching.

[0028] The seedling hardening period is 120 days after emergence, when the seedlings have 4 or more true leaves and the stems gradually lignify. At this time, a 30% low shading net is used to filter out only the strong midday sun, maximizing light exposure to promote seedling hardening and improve transplanting resistance.

[0029] It should be noted that the above is the conventional growth cycle division for tea seedlings. In actual production, the timing of switching the shading net can be flexibly adjusted according to the specific seedling variety, local climate, and light conditions in the seedling shed. The tea seedlings should also be observed manually on a regular basis, and the shading strategy should be adjusted according to the actual growth of the seedlings to ensure the accuracy of light matching.

[0030] The number of support components 6 and guide rails 3 corresponds to the number of shade nets 4. That is, each shade net 4 is equipped with a set of support components 6 and two guide rails 3 arranged parallel to each other on both sides of the bed frame 1, so that each support component 6 can move independently along the corresponding guide rail 3 and there will be no movement interference between adjacent support components 6.

[0031] Understandably, by using an automatic traction mechanism to drive the target support component 6 to slide along the guide rail 3, the shade net 4 with the corresponding shading rate can be pulled out and unfolded from the winding component 9 to achieve shading treatment for the tea seedling area. When the shade net 4 with the corresponding shading rate is not needed, the automatic traction mechanism can drive the support component 6 to reset, and the winding component 9 can automatically wind up the shade net 4 to switch the shading level.

[0032] In one embodiment of this application, such as Figures 3-6As shown, each set of support components 6 includes a support rod 61, two columns 62 and two guide sleeves 63. The two columns 62 are arranged vertically and parallel to each other, and the two ends of the two columns 62 are respectively connected to the support rod 61 and the two guide sleeves 63 to form a U-shaped frame structure. The two guide sleeves 63 are slidably arranged on the corresponding guide rails 3, and each of the two guide sleeves 63 has an insertion hole 64.

[0033] Understandably, the guide sleeve 63 is fitted on the outside of the guide rail 3 and can slide stably along the guide rail 3, thereby driving the support rod 61 and the column 62 to move synchronously. The insertion hole 64 is used to cooperate with the connecting component 8 to realize the connection of the connecting component 8 to the support component 6, so as to facilitate the automatic traction mechanism to drive the target support component 6 to move.

[0034] It should be noted that polyurethane dustproof rings (not shown in the figure) are provided at both ends of the guide sleeve 63. The dustproof rings are fitted to the outer wall of the guide rail 3. When the guide sleeve 63 slides along the guide rail 3, the dustproof rings can simultaneously scrape off tea leaves, dust and residual nutrient solution crystals attached to the surface of the guide rail 3, ensuring the smooth sliding of the guide sleeve 63 over a long period of time.

[0035] In one embodiment of this application, such as Figure 9 As shown, each winding assembly 9 includes a winding shaft 91, two limiting sleeves 92, two springs 93, and two caps 94. The winding shaft 91 is rotatably mounted inside the two side plates 5 via sealed bearings, and both ends of the winding shaft 91 extend outwards. The two springs 93 are respectively sleeved on the outside of the two extended ends of the winding shaft 91, and the inner ends of the springs 93 are fixed to the winding shaft 91. The springs 93 are used to provide the winding torque for automatic rotation of the winding shaft 91. Their torsional stiffness coefficient can be preset according to the unfolded length and weight of the corresponding shade net 4 to ensure that the springs 93 can drive the winding shaft 91 to wind stably.

[0036] Two limiting sleeves 92 are fixedly installed on the corresponding side plates 5 and connected to the cover 94. Two spring springs 93 are located inside the corresponding limiting sleeves 92, and the outer end of the spring spring 93 is connected to the corresponding limiting sleeve 92. The limiting sleeves 92 can be sealed by the cover 94 to prevent external dust and impurities from entering and affecting the performance of the spring spring 93.

[0037] One end of the shade net 4 is fixed and wrapped around the outer wall of the winding shaft 91, and the other end of the shade net 4 is connected to the support rod 61.

[0038] Understandably, when the automatic traction mechanism drives the corresponding support component 6 to move away from the winding component 9 along the guide rail 3, the shading net 4 with the corresponding shading rate is simultaneously pulled out from the winding shaft 91, thus achieving targeted shading for the tea seedlings. At the same time, the winding shaft 91 rotates and drives the spring 93 to elastically twist and accumulate torque.

[0039] Furthermore, when the automatic traction mechanism drives the support assembly 6 to reset, the spring spring 93 releases the stored elastic torque to drive the winding shaft 91 to rotate in the opposite direction, automatically rewinding the shade net 4 onto the outer wall of the winding shaft 91, thereby completing the automatic winding of the shade net 4.

[0040] In one embodiment of this application, such as Figure 7 , Figure 8 As shown, each automatic traction mechanism includes a traction component 7 and a connecting component 8. The traction component 7 includes a drive member 71, a traction wheel 72, a traction belt 73, and a guide wheel 74. The drive member 71 is disposed on the corresponding side plate 5, and the drive end of the drive member 71 is connected to the traction wheel 72. The guide wheel 74 is disposed on the bed frame 1. The traction belt 73 is sleeved on the outside of the guide wheel 74 and the traction wheel 72 to form a circular traction circuit.

[0041] It should be noted that the outer walls of the guide wheel 74 and the traction wheel 72 are both provided with limiting grooves (not shown in the figure) that are adapted to the traction belt 73. The traction belt 73 is fitted into the limiting grooves, which can prevent the traction belt 73 from derailing or slipping during transmission.

[0042] The drive unit 71 uses a geared motor, which can rotate forward and reverse according to control commands, thereby driving the traction wheel 72 to rotate in both directions, controlling the traction belt 73 to circulate in a clockwise or counterclockwise direction, and realizing the adjustment of the position of the connecting component 8.

[0043] In addition, limit switches (not shown in the figure) are provided at both ends of the guide rail 3 to control the travel distance of the connecting component 8 and improve the stability of the equipment operation.

[0044] In one embodiment of this application, such as Figure 7 , Figure 8 As shown, the connecting assembly 8 includes a sliding seat 81, a mounting bracket 82, multiple electromagnets 83, and multiple insertion rods 85. The mounting bracket 82 is disposed on the sliding seat 81, and the multiple insertion rods 85 are slidably disposed within the mounting bracket 82, with the bottom end of the insertion rods 85 extending into the interior of the sliding seat 81. The mounting bracket 82 is U-shaped and is used to limit the position of the insertion rods 85.

[0045] Each of the multiple insertion rods 85 has an adsorption plate 87 made of ferromagnetic material at its top end, and each of the multiple insertion rods 85 is fitted with an elastic element 84 and a retaining ring 86 is fixedly installed. The retaining ring 86 is located between the mounting frame 82 and the sliding seat 81. The two ends of the elastic element 84 abut against the retaining ring 86 and the sliding seat 81 respectively. Multiple electromagnets 83 are fitted on the outside of the corresponding insertion rods 85 and are connected to the mounting frame 82.

[0046] The electromagnet 83, the insertion rod 85, the retaining ring 86, and the elastic element 84 together constitute a magnetically triggered extension and retraction engagement mechanism. In this embodiment, there are three engagement mechanisms.

[0047] The sliding seat 81 is slidably mounted on the corresponding guide rail 3 and connected to the traction belt 73. The positions of the multiple insertion rods 85 correspond to the positions of the corresponding insertion holes 64.

[0048] It should be noted that the elastic element 84 is a compression spring, and its elastic coefficient can be preset according to actual usage requirements.

[0049] Understandably, when the electromagnet 83 is not energized, the elastic element 84 pushes the retaining ring 86 to move the insertion rod 85 upward. At this time, the bottom end of the insertion rod 85 retracts into the sliding seat 81 and does not engage with the guide sleeve 63. When the shade net 4 needs to be unfolded, the corresponding electromagnet 83 is energized to generate magnetic force, attracting the adsorption plate 87. The insertion rod 85 overcomes the elastic force of the elastic element 84 and moves downward, inserting into the insertion hole 64 of the corresponding guide sleeve 63. This completes the connection between the connecting component 8 and the corresponding support component 6. At this time, the connecting component 8 can move synchronously with the support component 6 along with the traction belt 73, realizing the unfolding of the corresponding shade net 4.

[0050] It should be further explained that the three engagement mechanisms within the connecting component 8 only activate one set corresponding to the target support component 6 at a time, ensuring that only the shade net 4 of the required shading level is pulled out. When it is necessary to switch the shading level, after the traction component 7 is reset, it is only necessary to disconnect the currently connected engagement mechanism and then activate the engagement mechanism of the corresponding target support component 6 to complete the switching of the traction object.

[0051] In addition, the two automatic traction mechanisms are symmetrically arranged and are synchronously controlled by a single-chip microcomputer to ensure that the transmission speed of the traction belts 73 on both sides of the bed frame 1 is consistent.

[0052] Furthermore, the control of the drive unit 71, electromagnet 83, and limit switch in this application is all accomplished through a single-chip microcomputer control system, which is a conventional method in the prior art and will not be elaborated here.

[0053] Specifically, in actual use, tea seedling trays are placed on seedbed net 2 to cultivate tea seedlings. During the seedling cultivation process, the required shading rate is determined according to the growth stage of the tea seeds: during the germination and sprouting stage of tea seeds, which is the tender seedling stage, the light requirement is low. At this time, a shading net 4 with a 75% shading rate is selected. Then, the electromagnet 83 of the corresponding insertion mechanism in the connecting component 8 is energized. The insertion rod 85 of the insertion mechanism is inserted into the insertion hole 64 of the corresponding guide sleeve 63. The connecting component 8 is then connected to the target support component 6 (which is connected to the shading net 4 with a 75% shading rate).

[0054] Then, the drive unit 71 is activated, and the traction belt 73 drives the connecting component 8 and the target support component 6 to move away from the winding component 9 along the corresponding guide rail 3, pulling the shading net 4 with a 75% shading rate out from the winding shaft 91 and unfolding it to cover the seedling area to complete the shading.

[0055] When it is necessary to switch the shading level, the drive component 71 reverses, and the traction belt 73 drives the support component 6 to reset through the connecting component 8. Under the action of the spring 93, the shading net 4 with a 75% shading rate automatically winds up to the outer wall of the winding shaft 91. Then, the corresponding electromagnet 83 is de-energized, and the elastic component 84 pushes the insertion rod 85 to disengage from the insertion hole 64. The connecting component 8 is disconnected from the current support component 6. At this time, the support component 6 connected to the corresponding shading net 4 is reconnected according to the above steps to complete the shading level switch. For example, according to the actual shading needs, it can be switched to a shading net with a 50% shading rate.

[0056] It should be noted that during the initial stage of tea seedling cultivation, when placing the tea seedling trays, the shade net 4 is completely rolled up and stored. At this time, the area above the seedling area is fully exposed, which can meet the environmental temperature requirements before budding. Natural light is used to increase the temperature of the seedbed substrate and accelerate the germination speed of the tea seeds. Moreover, the shade net 4 will not obstruct the placement of the seedling trays, making it convenient for staff to quickly complete the placement and improving the efficiency of pre-seedling preparation.

[0057] In summary, the tea seedling raising device for tea tree cultivation according to the embodiments of this application, by setting up a multi-layer roll-up shading mechanism and using multiple sets of independent and controllable support components with shading nets of different shading rates, can conveniently adjust the shading level according to the light requirements of the tea seed germination stage and the seedling growth period, ensuring the quality of tea tree seedling raising. It can be adapted to the production needs of large-scale factory seedling raising. Moreover, the roll-up storage structure can automatically store the corresponding shading net when it is not in use, which not only does not affect the seedling raising operation, but also extends the service life of the shading net and reduces the damage to the shading net caused by the external environment.
