Description

Technical Field

[0001] This invention relates to the field of seedling cultivation technology, specifically to a seedling cultivation device for vegetable planting. Background Technology

[0002] With the rapid development of modern agriculture, the vegetable planting industry is transforming and upgrading towards large-scale and intensive production. Seedling cultivation is a key link in vegetable production, and its quality directly affects crop yield and quality. Traditional seedling cultivation mainly relies on manual operation, setting up fixed cultivation troughs in greenhouses or sheds, and managing it through manual watering, fertilization, and soil loosening.

[0003] In existing technologies, the current cultivation devices suffer from fragmented workflows due to their single-function design, making it difficult to meet the demands of efficient and continuous production. Furthermore, when faced with large-scale seedling cultivation, they lack the ability to manage different zones and cannot automatically adjust water and fertilizer concentrations and cultivation depth according to different growth stages of the seedlings. This results in insufficient precision cultivation, making it difficult to meet the high-efficiency and precision requirements of modern vegetable seedling factory production. Therefore, a seedling cultivation device for vegetable cultivation is needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a seedling cultivation device for vegetable planting. It solves the problems of existing cultivation devices having a single function, resulting in fragmented operation processes, making it difficult to meet the needs of efficient and continuous production. Furthermore, when facing large-scale seedling cultivation, the lack of zoning management capabilities makes the equipment unable to adapt to the high-efficiency and precision requirements of modern vegetable seedling factory production.

The top side of the lifting frame penetrates the bottom side of the inner wall of the housing, and guide grooves are provided on both sides of the front end of the traction frame. The two opposite sides of the two lifting frames are slidably connected inside the guide grooves.

[0017] Preferably, the push-pull assembly includes a sliding sleeve slidably connected to the front end of the bottom side of the inner wall of the housing, a plug shaft sliding vertically inside the sliding sleeve, the bottom side of the plug shaft being fixedly connected to the rear end of the tiller, a crank connecting rod being rotatably connected to the rear end of the sliding sleeve, and the top end of the crank connecting rod being rotatably connected to the outer circumference of the bottom side of the driven gear.

[0018] Preferably, it also includes a take-up roller, which is rotatably connected to the front end of the housing. A steel wire rope is wound around the outer wall of the take-up roller. One side of the spray frame is rotatably connected to the front side of the housing through a torsion spring. The other side of the spray frame is connected to the end of the steel wire rope. A worm gear is connected to one side of the take-up roller through a synchronous belt and a synchronous pulley. The outer wall of the transmission rod is connected to the worm gear through a worm sleeve.

[0019] Preferably, it also includes a sliding rail, which is fixedly connected to the top of the base frame and has a sliding sleeve that slides horizontally on its outer wall. The bottom end of the sliding sleeve is slidably connected to the top side of the traction shaft.

[0020] Working principle: During seedling cultivation, the shell moves on the main track via electric wheels on the bottom side. When it reaches the turning track, the turning wheel rotates the turning track together with the top shell, aligning the turning track with the branch track at the current position. This moves the shell onto the path of the branch track, with the side of the shell with the spray rack facing the cultivation tank. At this time, the following operations are performed:

[0021] After the structure inside the shell is turned by the steering wheel and the steering track, it is limited by the sliding sleeve, which will cause the traction shaft to rotate. The opening of the sliding sleeve faces the culture tank. When the shell moves to the culture area of ​​the next culture tank, the sliding sleeve is driven by the traction shaft and moves together. When the shell moves towards the culture tank, the traction shaft disengages through the opening of the sliding sleeve.

[0022] When the rotating drive shaft rotates through two synchronous pulleys of different sizes and a synchronous belt drive rod, the drive rod will rotate several times, causing the worm sleeve on its outer wall to rotate and mesh with the worm wheel to rotate. The worm wheel then rotates through the synchronous pulley and synchronous belt drive the take-up roller, thereby causing the take-up roller to release the rope. The spray frame, no longer restrained by the wire rope, will then be lowered.

[0023] The rotating transmission rod moves the transmission frame at the bottom of the meshing joint downwards, causing the transmission frame to pull the connecting rod one connected to it, causing the traction frame to move to the rear end and pull the connecting rod two, so that the connecting rod two no longer supports the lifting rotating seat connected to its top, causing the lifting rotating seat to move downwards from its original raised state, thereby causing the trigger gear two on the top side of the lifting rotating seat to move downwards synchronously, so that the trigger gear two no longer meshes with the trigger gear one on the top side, and the trigger gear two meshes with the driven gear two. The moving traction frame then moves the lifting frame connected to the sleeve through the traction chute, causing the sleeve to move downwards in conjunction with the structure including the loosening plow and the plug shaft, so that the loosening plow contacts the cultivation soil in the cultivation tank.

[0024] During the displacement of the shell on the branch track, the power gear on the bottom side of the shell meshes with the toothed rail on the branch track, causing the power gear to rotate together with the power shaft connected to it. This causes the power shaft to drive the trigger gear two connected to the spline shaft to rotate, causing the driven gear two, which is engaged with the trigger gear two at this time, to rotate. The rotating driven gear two pulls the traction frame on the bottom side to move back and forth and drives the eccentric wheel connecting rod structure formed by the crank connecting rod to push and pull the sliding sleeve back and forth. The traction frame moving back and forth pulls the water and fertilizer delivery piston pump back and forth, causing the water and fertilizer delivery piston pump to continuously draw liquid from the mixing cylinder and deliver it to the spray frame for fertilization. The sliding sleeve moving back and forth drives the plug shaft connected to the loosening plow inside it, causing the loosening plow to plow the culture soil in the cultivation tank, preventing the culture soil from clumping and allowing the seedling roots to extend better.

[0025] After completing the cultivation work in the current area's cultivation tank, the shell returns to the main track path, and resets the structures including the soil loosening plow, spray frame, trigger gear two, and traction frame, as well as those connected to it. When it reaches the branch track next to the cultivation tank in the next area, the above process is repeated.

[0026] As the housing travels along the main track and steering track, the guide head will move along the guide path groove, causing the continuously downward-moving guide head to squeeze the piston rod of the fertilizer delivery piston pump. This causes the fertilizer stored in the fertilizer delivery piston pump to be sequentially input into the mixing cylinder through the connecting cylinder and the delivery pipe, where it mixes with clean water. When the power gear meshes with the gear rails in the main track and steering track, it drives the trigger gear two to rotate. At this time, the trigger gear two has disengaged from the driven gear two and meshes with the trigger gear one through the meshing teeth, causing the trigger gear one to rotate along with the trigger gear two. The trigger gear one also meshes with the driven gear one connected to the stirring shaft, causing the stirring shaft to agitate inside the mixing cylinder. This mixes the measured amount of fertilizer input into the mixing cylinder with clean water, preparing a water-fertilizer solution of the corresponding concentration required for the current area. When the housing reaches the end of the guide frame, it will move in the opposite direction to reset, allowing the guide head to enter another part of the path. When it reaches the end of the guide path groove, it will push open the one-way limit head and return to the starting position of the guide path groove.

[0027] This invention provides a seedling cultivation device for vegetable planting. It has the following beneficial effects:

[0028] 1. This invention realizes integrated operation of the cultivation process, completely eliminates the waiting time for switching between multiple devices, and the highly integrated structure greatly reduces the number of equipment purchased and the floor space occupied, providing a high-performance automated solution for large-scale seedling production and making vegetable planting production more efficient.

[0029] 2. This invention achieves precise and differentiated cultivation management throughout the entire growth cycle. It can simultaneously support multiple seedling areas in the germination, cotyledon, true leaf, and hardening stages, and can automatically match the optimal water and fertilizer concentration according to the physiological needs of each area, ensuring that seedlings are in the best growth environment at each stage.

[0030] 3. This invention can autonomously complete the entire process of transferring the cultivation area, switching the operation status, and resetting the actuator, achieving true closed-loop operation and meeting the stringent production requirements of modern seedling factories for standardization, continuous operation, and high reliability.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example:

[0049] This invention provides a seedling cultivation device for vegetable planting, comprising:

[0050] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 15 The base frame 1 has one end that is moved by the distribution track line to transport the housing 6 to carry out cultivation work on the planting area of ​​multiple cultivation tanks 2 set at the other end of the base frame 1. A guide frame 12 is fixedly connected to one end of the top side of the base frame 1. A guide path groove is opened on the surface of the guide frame 12. A one-way limiting head 42 is rotatably connected to the intersection of the starting point and the ending point of the guide path groove through a torsion spring.

[0051] Specifically, the interior of the cultivation trough 2 is used to place the cultivation soil for growing vegetable seedlings, and the cultivation trough 2 is divided into four areas from left to right: the area for growing seedlings in the germination stage, the area for growing seedlings in the cotyledon unfolding stage, the area for growing seedlings in the true leaf growth stage, and the area for growing seedlings in the hardening stage.

[0052] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 14 The distribution track includes a main track 3 fixedly connected to one end of the top side of the base frame 1 and multiple branch tracks 4. The branch tracks 4 are located on one side of the culture tank 2. The main track 3 is connected to the branch tracks 4 through a steering track 5 steered by a steering wheel 39. The steering wheel 39 is located at one end of the top side of the base frame 1 and is driven by a motor to rotate. The housing 6 is displaced on the main track 3, branch tracks 4 and steering tracks 5 through electric walking wheels 7 installed on the bottom side. The inner walls of the main track 3, branch tracks 4 and steering tracks 5 are all fixedly connected with gear rails for the meshing and rotation of the power gear 8.

[0053] Specifically, the toothed rails on the main track 3 and the turning track 5 are continuous, maintaining engagement with the power gear 8 without interruption, ensuring continuous transmission. The toothed rails on the branch track 4, however, are segmented and spaced out, positioned in areas without seedlings to prevent damage during soil loosening. Spacing between seedlings also prevents root entanglement. During seedling cultivation, the shell 6 moves on the main track 3 via the electric wheels 7 on its bottom side. When it reaches the turning track 5, the turning wheel 39 rotates the turning track 5 in conjunction with the top shell 6, aligning the turning track 5 with the current branch track 4. This allows the shell 6 to move onto the path of the branch track 4, with the side of the shell 6 with the spray rack 9 facing the cultivation tank 2.

[0054] Please see the appendix Figure 4 -Appendix Figure 6The mixing cylinder 13 is fixedly connected to the inside of the housing 6. The mixing cylinder 13 is filled with clean water. When the housing 6 moves in the area close to the guide frame 12, the guide frame 12 guides the fertilizer delivery component to deliver fertilizer into the mixing cylinder 13 at regular intervals through the guide path groove opened on one side of the guide frame 12. The fertilizer is then mixed by the stirring shaft 46 rotating inside the mixing cylinder 13, gradually producing a higher concentration of water and fertilizer to adapt to the different stages of seedling cultivation in the planting areas of multiple cultivation tanks 2. The fertilizer delivery component includes a fertilizer liquid delivery piston pump 14 located on the rear side of the mixing cylinder 13. A guide head 11 is fixedly connected to the top of the fertilizer liquid delivery piston pump 14. The middle end of the guide head 11 slides vertically on the rear side of the housing 6. The rear end of the guide head 11 is located in the guide path groove opened on the surface of the guide frame 12. A connecting cylinder 18 is fixedly connected to the bottom output end of the fertilizer liquid delivery piston pump 14. An infusion pipe 15 is fixedly connected to the output end of the connecting cylinder 18. The output end of the infusion pipe 15 is located at the top of the inside of the mixing cylinder 13.

[0055] Specifically, the guide path trough is characterized by a gradually decreasing path, allowing the fertilizer solution delivery piston pump 14 to be pressed downwards by the guide head 11. During the continuous downward pressing period, a fixed amount of fertilizer solution is quantitatively input into the mixing cylinder 13, mixing with water to form a liquid fertilizer. The closer to the end of the guide path trough, the higher the liquid fertilizer concentration in the mixing cylinder 13, with a maximum concentration of 1 / 2. The liquid fertilizer concentrations prepared for the areas of seedling germination, seedling cotyledon unfolding, seedling true leaf growth, and seedling hardening are 0, 1 / 8 to 1 / 4, 1 / 4 to 1 / 2, and 1 / 2, respectively. This allows the device to cultivate seedlings at multiple stages under suitable conditions at one time. As the housing 6 travels along the path of the main track 3 and the turning track 5, the guide head 11 will shift along the trajectory of the guide path groove. This downward-moving guide head 11 will compress the piston rod of the fertilizer delivery piston pump 14, causing the fertilizer solution stored in the pump to be sequentially input into the mixing cylinder 13 through the connecting cylinder 18 and the delivery pipe 15. There, it will mix with water, creating a solution of the required concentration for the current area. When the housing 6 reaches the end of the guide frame 12, it will move in the opposite direction to reset, allowing the guide head 11 to enter another part of the path. Upon reaching the end of the guide path groove, it will push open the one-way limit head 42 and return to the starting position of the guide path groove.

[0056] Please see the appendix Figure 6 -Appendix Figure 8The power shaft 20 is rotatably connected to the bottom side of the housing 6. A power gear 8 is fixedly connected to the bottom side of the power shaft 20. A trigger gear set is installed on the top side of the power shaft 20 to trigger either the driven gear 17 or the driven gear 22 meshing with the trigger gear set. The bottom side of the stirring shaft 46 is fixedly connected to the top side of the driven gear 17. A liquid delivery assembly is provided on the top side of the driven gear 22 to input water and fertilizer from the mixing drum 13 into the spray frame 9 on the front side of the housing 6 for fertilizing the seedlings. The trigger gear set includes a trigger gear 19 rotatably connected to the bottom side of the mixing drum 13 and a trigger gear 21 rotatably connected to the top side of the lifting rotary seat 32. The top side of the power shaft 20 is inserted into the middle end of the trigger gear 21 via a spline shaft. (See attached diagram.) Figure 10 Both trigger gear 19 and trigger gear 21 have meshing teeth on their adjacent sides. Trigger gear 19 meshes with driven gear 17. Driven gear 22 is located in front of trigger gear 21. The infusion assembly includes a connecting sliding frame 23. The connecting sliding frame 23 is fixedly connected to the bottom side of the inner wall of the base frame 1. One end of the connecting sliding frame 23 is rotatably connected to the top side of driven gear 22. A traction frame 25 slides horizontally on the bottom side of the connecting sliding frame 23. A water and fertilizer delivery piston pump 16 is installed on one side of the traction frame 25. The other side of the traction frame 25 is sleeved on the bottom outer periphery of driven gear 22. The outer wall of the water and fertilizer delivery piston pump 16 is fixedly connected to the bottom end of the connecting sliding frame 23. The input end of the water and fertilizer delivery piston pump 16 is connected to the mixing cylinder 13 through a hose. The output end of the water and fertilizer delivery piston pump 16 is connected to the input end of the spray frame 9 through a hose. A spray head is provided on the bottom side of the spray frame 9.

[0057] Specifically, during the displacement of the housing 6 on the branch track 4, the power gear 8 on the bottom side of the housing 6 meshes with the toothed rail on the branch track 4, causing the power gear 8 to rotate together with the power shaft 20 connected to it. This causes the power shaft 20 to drive the trigger gear 21 connected to the spline shaft to rotate, causing the driven gear 22 meshing with the trigger gear 21 to rotate. The rotating driven gear 22 pulls the traction frame 25 on the bottom side to move back and forth, and drives the eccentric wheel connecting rod structure formed by the crank connecting rod 24 to push and pull the sliding sleeve 35 back and forth. The traction frame 25 moving back and forth pulls the water and fertilizer delivery piston pump 16 back and forth, causing the water and fertilizer delivery piston pump 16 to continuously draw liquid from the mixing cylinder 13 and deliver it to the spray frame 9 for fertilization. The sliding sleeve 35 moving back and forth drives the plug shaft 36 connected to the loosening plow 10 inside it, causing the loosening plow 10 to plow the culture soil in the cultivation tank 2, preventing the culture soil from clumping and allowing the seedling roots to extend better. When the power gear 8 meshes with the gears in the main track 3 and the steering track 5, it drives the trigger gear 21 to rotate. At this time, the trigger gear 21 has disengaged from the driven gear 22 and meshes with the trigger gear 19 through the meshing teeth, causing the trigger gear 19 to rotate with the rotation of the trigger gear 21. The trigger gear 19 also meshes with the driven gear 17 connected to the stirring shaft 46, causing the stirring shaft 46 to be stirred inside the mixing cylinder 13.

[0058] Please see the appendix Figure 9 -Appendix Figure 11 The lifting rotating seat 32 slides vertically on the middle of the bottom side of the inner wall of the base frame 1. The lifting rotating seat 32 is raised and lowered by a lifting assembly, which is driven by a transmission rod 27 rotatably connected inside the housing 6. The top of the transmission rod 27 is connected to a traction shaft 26 via two synchronous pulleys of different sizes and a synchronous belt. The traction shaft 26 is rotatably connected to the top side of the housing 6. A traction assembly is provided on the front side of the lifting rotating seat 32 to pull the soil loosening plow 10 on the front side of the bottom of the housing 6 for raising and lowering. The soil loosening plow 10 pushes... The lifting assembly is connected to the bottom side of the driven gear 22. The lifting assembly includes a transmission frame 28 that slides vertically on the bottom side of the inner wall of the base frame 1 and a traction frame 29 that slides horizontally on the bottom side of the inner wall of the housing 6. The bottom end of the outer wall of the transmission rod 27 is threaded to the outer circumference of the transmission frame 28. The inner circumference of the transmission frame 28 is rotatably connected to two connecting rods 30. The bottom end of the connecting rods 30 is rotatably connected to the rear side of the traction frame 29. The top side of the rear end of the traction frame 29 is rotatably connected to a connecting rod 31. The left and right ends of the lifting turntable 32 are rotatably connected to the top end of the connecting rod 31.

[0059] Please see the appendix Figure 8 -Appendix Figure 12The traction assembly includes a sleeve 33 that slides vertically on the bottom side of the front end of the housing 6. The tiller 10 is slidably connected to the inner wall of the sleeve 33. Lifting frames 34 are fixedly connected to both ends of the sleeve 33. The top side of the lifting frame 34 penetrates the bottom side of the inner wall of the housing 6. Guide grooves are provided on both sides of the front end of the traction frame 29. The two lifting frames 34 are slidably connected to the inside of the guide grooves on opposite sides. The push-pull assembly includes a sliding sleeve 35 that slides on the front end of the bottom side of the inner wall of the housing 6. A plug shaft 36 slides vertically inside the sliding sleeve 35. The bottom side of the plug shaft 36 is fixedly connected to the rear end of the tiller 10. A crank connecting rod 24 is rotatably connected to the rear end of the sliding sleeve 35. The top end of the crank connecting rod 24 is rotatably connected to the outer periphery of the bottom side of the driven gear 22.

[0060] Specifically, the rotating transmission rod 27 moves the transmission frame 28 at the bottom of the meshing end downward, causing the transmission frame 28 to pull the connecting rod 30 connected to it, causing the traction frame 29 to move to the rear end and pull the connecting rod 31. The connecting rod 31 no longer supports the lifting rotating seat 32 connected to its top end, causing the lifting rotating seat 32 to move downward from its original raised state. This causes the trigger gear 21 on the top side of the lifting rotating seat 32 to move downward synchronously, so that the trigger gear 21 no longer meshes with the trigger gear 19 on the top side, and the trigger gear 21 meshes with the driven gear 22. The displaced traction frame 29 then moves the lifting frame 34 connected to the sleeve 33 through the traction chute, causing the sleeve 33 to move downward in conjunction with the structure including the loosening plow 10 and the plug shaft 36, so that the loosening plow 10 contacts the cultivation soil in the cultivation tank 2.

[0061] Please see the appendix Figure 4 and attached Figure 9 The take-up roller 45 is rotatably connected to the front end of the housing 6, and its outer wall is wound with steel wire rope. One side of the spray frame 9 is rotatably connected to the front side of the housing 6 through a torsion spring, and a limit structure is provided at the rotation point to keep the included angle between the spray frame 9 and the housing 6 at a maximum of 90°. The other side of the spray frame 9 is connected to the end of the steel wire rope. One side of the take-up roller 45 is connected to the worm gear 44 through a synchronous belt and synchronous pulley. The outer wall of the transmission rod 27 is connected to the worm gear 44 through the worm sleeve 43. The structure of the worm sleeve 43 is that the internal structure is sleeved and fixed on the transmission rod 27, and the transmission structure of its outer wall is no different from that of a normal worm, and it has the meshing transmission capability of a normal screw.

[0062] Specifically, when the rotating drive shaft 26 rotates through two synchronous pulleys of different sizes and a synchronous belt drive rod 27, the drive rod 27 will rotate several times, causing the worm sleeve 43 on its outer wall to rotate and mesh with the worm wheel 44 to rotate. The worm wheel 44 then drives the take-up roller 45 to rotate through the synchronous pulley and synchronous belt. The direction of rotation of the take-up roller 45 is determined by the rotation direction of the drive shaft 26 in conjunction with the subsequent transmission. When the take-up roller 45 is winding, it pulls the traction wire rope to rotate and lift the spray frame 9. During the lifting process, the torsion spring at the rotating part of the spray frame 9 is compressed. When the take-up roller 45 releases the rope, the spray frame 9, no longer restrained by the wire rope, will return to its original position through the compressed torsion spring.

[0063] Please see the appendix Figure 13 A sliding rail 37 is fixedly connected to the top of the base frame 1. A sliding sleeve 38 slides horizontally on its outer wall. The bottom end of the sliding sleeve 38 is slidably connected to the top side of the traction shaft 26. After the structure inside the housing 6 is turned by the steering wheel 39 and the steering rail 5, it is limited by the sliding sleeve 38, which will cause the traction shaft 26 to rotate. The opening of the sliding sleeve 38 faces the culture tank 2. When the housing 6 moves to the culture area of ​​the next culture tank 2, the sliding sleeve 38 is driven by the traction shaft 26 and moves together. When the housing 6 moves to the culture tank 2, the traction shaft 26 disengages through the opening of the sliding sleeve 38 and is reinserted during the reset.

[0064] Please see the appendix Figure 4 and attached Figure 6 The mixing cylinder 13 is equipped with a clean water delivery pipe 41, and the fertilizer solution delivery piston pump 14 is equipped with a fertilizer solution delivery pipe 40 for inputting clean water and fertilizer solution from the outside and storing them in the mixing cylinder 13 and the fertilizer solution delivery piston pump 14. Both the clean water delivery pipe 41 and the fertilizer solution delivery pipe 40 are equipped with a one-way valve diaphragm to prevent backflow.
