Description

Technical Field

[0001] This utility model relates to the field of agricultural seedling technology, and more specifically, it relates to a seedling raising device for agronomists. Background Technology

[0002] In modern agricultural seedling cultivation, precise nutrient solution supply is required for different crop varieties and growth stages to ensure seedling quality. Existing seedling equipment's nutrient solution delivery system mostly adopts a fixed flow pipeline design or a simple valve control method. Fixed flow systems cannot be adjusted according to the water and fertilizer requirements of different seedling stages, leading to root rot in seedlings due to excessive nutrient solution during germination, or insufficient nutrient solution during vigorous growth, which affects development. More importantly, existing adjustment mechanisms lack effective locking devices. After adjustment, the valve position is prone to drift due to pipeline pressure fluctuations or vibrations, making it impossible to maintain the preset flow parameters stably.

[0003] The unlocking operation of the existing locking mechanism is also cumbersome. Some devices require special tools to disassemble the locking parts for readjustment. It cannot respond quickly when the liquid supply parameters need to be adjusted urgently, which affects the flexibility and adaptability of seedling production. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a seedling raising device for agronomists to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: A seedling raising device for agronomists, comprising a support frame, on which a seedling box is fixedly mounted. The seedling box has multiple sets of input pipes, each with an input pipe fixedly mounted on its outer wall. A connecting sleeve is fixedly mounted at the top of each input pipe. An adjusting sleeve is rotatably mounted at the top of the connecting sleeve, and a connecting pipe is rotatably connected to the top of the adjusting sleeve. An outer pipe is fixedly mounted on the outer wall of the support frame, and a diversion pipe is connected to the outer wall of the outer pipe. Multiple diversion pipes are provided and fixedly connected to multiple sets of connecting pipes. A toothed ring is fixedly mounted on the inner side of the adjusting sleeve. Gears are rotatably mounted inside the connecting sleeve, with multiple sets of gears meshing with the toothed ring. A baffle is fixedly mounted on the inner side of each set of gears. A slider is fixedly mounted on the outer wall of the adjusting sleeve, with multiple sets of sliders and positioning blocks on their inner sides. A positioning sleeve is fixedly mounted on the outer wall of the connecting sleeve, and positioning holes are provided on the outer wall of the positioning sleeve, with multiple sets of positioning holes abutting against multiple sets of positioning blocks.

[0008] The present invention is further configured such that each of the multiple sets of positioning blocks has a fixed abutment block at its top, and the multiple sets of abutment blocks are slidably connected to multiple sets of sliders respectively. The outer wall of the connecting sleeve is slidably provided with a limiting sleeve, which realizes the pushing transmission of the positioning block and the guiding sliding function of the limiting sleeve. When the limiting sleeve slides along the connecting sleeve, the abutment block transmits the thrust to the positioning block, causing it to move along the slider and insert into the positioning hole. The sliding cooperation between the abutment block and the slider ensures that the movement trajectory of the positioning block is accurate and avoids jamming. The sliding stroke of the limiting sleeve limits the insertion depth of the positioning block to ensure the reliability of positioning. This structure converts the axial thrust into the radial insertion movement of the positioning block to achieve precise locking of the position of the adjusting sleeve.

[0009] The present invention is further configured such that a tension spring is connected between each of the multiple sets of positioning blocks and the slider, providing an elastic return force for the positioning blocks to automatically reset. The tension spring is stretched and stores elastic potential energy when the positioning block is pushed into the positioning hole. When unlocking, the tension spring automatically pulls the positioning block out of the positioning hole along the slider to restore the initial position, ensuring that the unlocking operation is fast and reliable without the need to manually pull out the positioning block. The continuous tension of the tension spring compensates for the gap between the positioning block and the abutment block, making the unlocking action more sensitive.

[0010] The present invention is further configured such that a guide block is fixedly provided on the inner side of the limiting sleeve. The guide block is provided in multiple sets and is slidably connected to the connecting sleeve, providing precise guidance and anti-deflection function for the sliding of the limiting sleeve. The multiple sets of guide blocks limit the trajectory of the limiting sleeve along the axial direction of the connecting sleeve to prevent the limiting sleeve from deflecting due to uneven force. The sliding cooperation between the guide block and the connecting sleeve ensures that the limiting sleeve moves smoothly without jamming. The distributed design of the multiple sets of guide blocks makes the limiting sleeve bear force evenly and improves the force transmission efficiency when pushing the positioning block. This structure ensures that the positioning block can be accurately aligned with the positioning hole and smoothly inserted.

[0011] This utility model is further configured such that an arc-shaped rod is fixedly provided on the outer wall of the limiting sleeve, and multiple sets of the arc-shaped rod are provided. A rotating sleeve is rotatably provided on the outer wall of the connecting sleeve, and a limiting rod is fixedly provided on the outer wall. Multiple sets of the limiting rod are provided, and each set of the limiting rod has a limiting hole on its outer wall. The multiple sets of the limiting rod are respectively inserted into the multiple sets of limiting holes, realizing the secondary fixing and quick unlocking function of the locking position of the limiting sleeve. When the rotating sleeve rotates, it drives the multiple sets of limiting rods to rotate, causing the arc-shaped rod to be inserted into the limiting hole to axially restrict the limiting sleeve. The arc design of the arc-shaped rod makes the insertion process smooth and easy to rotate and unlock. The cooperation between the multiple sets of arc-shaped rods and the limiting holes provides reliable locking strength to prevent the limiting sleeve from retracting under pressure. This mechanism ensures that the insertion state of the positioning block in the positioning hole is stable and durable.

[0012] The present invention is further configured such that the bottom ends of the multiple sets of positioning blocks and the outer sides of the multiple sets of positioning holes are all arc-shaped, providing guidance and smooth operation for the insertion of the positioning blocks. The arc-shaped contact surface enables the positioning blocks to automatically center and reduce insertion resistance when moving towards the positioning holes, avoiding insertion difficulties or jamming caused by the deviation between the positioning block and the positioning hole axis. The arc transition eliminates sharp corner contact and reduces local stress concentration, so that the positioning mechanism can still maintain good insertion and removal feel and positioning accuracy after long-term use.

[0013] The present invention is further configured such that all of the multiple sets of baffles are fan-shaped and have rounded corners on the outer side, which optimizes the flow characteristics of the nutrient solution and reduces the flow resistance. When the fan-shaped baffle rotates with the gear, the cross-sectional area of ​​the flow channel can be smoothly adjusted to achieve continuous and adjustable flow rate. The rounded corner design avoids the generation of eddies and turbulence when the liquid flows through the baffle, reducing energy loss. The rounded corner shape reduces the impact force between the baffle and the nutrient solution when the baffle rotates, making the flow rate adjustment process more stable. This structure extends the service life of the baffle and improves the linearity of flow rate adjustment.

[0014] The present invention is further configured such that all of the multiple sets of diversion pipes are made of flexible hoses, which provides flexible connection and installation convenience for the nutrient solution delivery system. The hoses can adapt to slight angle changes in the connecting pipes when the adjusting sleeve rotates, avoiding stress concentration in the pipeline. The flexibility of the hoses makes the installation and replacement process more convenient without the need for precise alignment of the pipeline interfaces. The elasticity of the hoses absorbs pressure fluctuations in the pipeline, reducing the impact on the connecting components. This design improves the reliability of the delivery system and reduces the difficulty of maintenance.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a seedling raising device for agronomists, which has the following beneficial effects:

[0017] 1. This device uses a flow regulation mechanism that drives multiple sets of gears to rotate synchronously through a rotating adjusting sleeve and a gear ring meshing transmission to control the nutrient solution supply. Compared with the traditional manual valve adjustment method, this mechanism realizes the separate adjustment of multiple liquid supply channels, ensuring that each seedling box receives a balanced supply of nutrient solution. The rotation angle of the baffle is linearly related to the flow rate, which makes it easy for operators to quickly set appropriate parameters according to the seedling needs. This effectively solves the problems that fixed flow systems cannot adapt to the needs of different growth stages and the poor adjustment accuracy of manual valves.

[0018] 2. This device achieves reliable position fixing through a double locking mechanism where pushing the limiting sleeve causes the abutment block to press the positioning block into the positioning hole, and the arc-shaped rod is inserted into the limiting hole. The arc-shaped positioning block and the positioning hole mating surface make the insertion process smooth and easy. Multiple sets of guide blocks limit the movement trajectory of the limiting sleeve to ensure accurate positioning. Compared with the traditional threaded locking method, this mechanism provides mechanical double protection. The insertion and fixing of the positioning block and the positioning hole prevents the adjusting sleeve from rotating due to pressure fluctuations. The arc-shaped rod restricts the limiting sleeve to ensure that the positioning block always stays in the positioning hole. The operator can intuitively judge whether the locking is in place by pushing the limiting sleeve and rotating the rotating sleeve. This effectively eliminates the problem of flow parameter drift caused by poor locking.

[0019] 3. This device provides a convenient operation for flow readjustment by using a rotating sleeve to release the arc-shaped rod limit and a quick unlocking mechanism that automatically pulls back the positioning block with a tension spring. Compared with traditional locking mechanisms that require tools to disassemble or repeated loosening, this mechanism achieves the linkage unlocking of all locking components with a single rotation and a single pull. The automatic pull-back function of the tension spring avoids difficulty in disengaging the positioning block due to friction or foreign objects. The entire unlocking process is simple to operate and requires no special tools. The flexible hose design of the diverter tube can adapt to slight movement of the pipeline during adjustment to avoid stress concentration, significantly improving the response speed of parameter adjustment in seedling production and reducing the labor intensity of operators.

An outer pipe 7 is fixedly mounted on the outer wall of the support frame 1, and a diversion pipe 8 is connected to the outer wall of the outer pipe 7. Multiple sets of diversion pipes 8 are fixedly mounted and each is fixedly connected to a set of connecting pipes 6. A toothed ring 9 is fixedly mounted inside the adjusting sleeve 5. Gears 10 are rotatably mounted inside the connecting sleeve 4, with multiple sets of gears 10 meshing with the toothed ring 9. A baffle 11 is fixedly mounted inside each set of gears 10. A slider 12 is fixedly mounted on the outer wall of the adjusting sleeve 5, with multiple sets of sliders 12, each with a positioning block 13 on its inner side. A positioning sleeve 14 is fixedly mounted on the outer wall of the connecting sleeve 4, with positioning holes 15 opening on its outer wall. Multiple sets of positioning holes 15 abut against multiple sets of positioning blocks 13.

[0030] In this embodiment, during use, the external pipe 7 is connected to the external culture medium delivery pipe, and then enters the input pipe 3 through the multi-component flow pipe 8, and enters the seedling box 2 for cultivation through the input pipe 3. When it is necessary to adjust the flow rate of the culture medium, the rotating adjustment sleeve 5 drives the gear ring 9 to rotate and mesh with the multi-set gear 10 to rotate, so that the multi-set gear 10 drives the baffle 11 to rotate to adjust the flow area of ​​the culture medium, thereby controlling the flow rate of the culture medium. After the adjustment is completed, the limiting sleeve 17 is pushed to abut against the top of the multi-set abutment block 16, so that the multi-set abutment block 16 pushes the positioning block 13 to abut against the positioning hole 15 to position the adjustment sleeve 5. The rotating sleeve 200 drives the multi-set limiting rod 21 to rotate, so that the arc rod 20 is inserted into the limiting hole 22 to restrict the limiting sleeve 17.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: the top of each of the multiple positioning blocks 13 is fixedly provided with an abutment block 16, the multiple abutment blocks 16 are slidably connected to the multiple sliders 12 respectively, and the outer wall of the connecting sleeve 4 is slidably provided with a limiting sleeve 17.

[0032] Each of the multiple positioning blocks 13 and the slider 12 is connected by a tension spring 18.

[0033] A guide block 19 is fixedly provided on the inner side of the limiting sleeve 17. Multiple sets of guide blocks 19 are provided and all are slidably connected to the connecting sleeve 4.

[0034] The outer wall of the limiting sleeve 17 is fixedly provided with an arc-shaped rod 20, and multiple sets of arc-shaped rods 20 are provided.

[0036] All sets of baffles 11 are fan-shaped and have rounded corners on the outside.

[0037] All 8 component flow tubes are configured as flexible tubes.

[0038] More specifically, when the flow rate needs to be adjusted again, rotating the rotating sleeve 200 drives multiple sets of limiting rods 21 to disengage the arc rod 20 from the limiting hole 22, releasing the restriction on the limiting sleeve 17. Pulling the limiting sleeve 17 releases the abutment of multiple sets of abutting blocks 16. Through multiple sets of tension springs 18, the positioning block 13 is pulled away from the positioning hole 15, releasing the positioning of the adjusting sleeve 5. Then, the adjusting sleeve 5 can be rotated again to adjust the rotation angle of multiple sets of baffles 11.

[0039] In summary, during use or operation of the overall equipment: When in use, connect the external pipe 7 to the external culture medium delivery pipeline, then allow it to enter the input pipe 3 through the multi-component flow pipe 8, and finally into the seedling box 2 for cultivation. When the flow rate of the culture medium needs to be adjusted, rotate the adjusting sleeve 5 to drive the gear ring 9 to rotate and mesh with multiple sets of gears 10, causing the multiple sets of gears 10 to drive the baffle 11 to rotate and adjust the flow area of ​​the culture medium, thereby controlling the flow rate. After adjustment, push the limiting sleeve 17 to abut against the top of the multiple sets of abutting blocks 16, causing the multiple sets of abutting blocks 16 to push the positioning block 13 to abut against the positioning hole 15 to position the adjusting sleeve 5. Rotate the rotating sleeve 200 to drive the multiple sets of limiting rods 21 to rotate, causing the arc-shaped rod 20 to insert into the limiting hole 22 to restrict the limiting sleeve 17.

[0040] When the flow rate needs to be adjusted again, rotating the rotating sleeve 200 drives multiple sets of limiting rods 21 to disengage the arc rod 20 from the limiting hole 22, releasing the restriction on the limiting sleeve 17. Pulling the limiting sleeve 17 releases the abutment of multiple sets of abutting blocks 16. Through multiple sets of tension springs 18, the positioning block 13 is pulled away from the positioning hole 15, releasing the positioning of the adjusting sleeve 5. Then, the adjusting sleeve 5 can be rotated again to adjust the rotation angle of multiple sets of baffles 11.
