Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and in particular to an eggplant seedling cultivation method and a seedling cultivation device. Background Art

[0002] When cultivating eggplant, the skin of eggplant seeds is relatively hard and they are prone to lose their germination ability after being stored for a certain period of time. The seeds need to be soaked before planting to allow the seeds to absorb sufficient water, which can promote the germination and growth of eggplant. It can also prevent and control soil-borne diseases and increase the germination rate of seeds.

[0003] A seedling raising device for planting eggplant and pepper with publication number CN215648131U has a seed soaking box fixedly arranged in the device body, which is filled with water, and then the screen plate of the seed soaking screen is opened to put seeds in, and after the seed soaking screen is engaged with the lifting column, the lifting column is controlled to move downward to soak the seed soaking screen in the seed soaking box, and when the seed soaking is completed, the lifting column is raised to remove the seed soaking screen to complete the seed soaking. However, after the seeds are soaked, they will adhere to the inner wall of the seed soaking screen, and it is difficult for the staff to recover the seeds attached to the inner wall of the seed soaking screen.

[0019] A transparent window is embedded on the surface of the incubator, the transparent window is made of acrylic, and the liquid storage tank is made of transparent material.

[0020] An eggplant seed cultivation method using an eggplant seedling raising device comprises the following steps:

[0021] Step 1: Select high-quality seeds by observing the color and fullness of eggplant seeds;

[0022] Step 2: Put the selected seeds into the storage assembly, that is, pull the bottom plate downward so that there is a gap between the bottom plate and the lower end surface of the seed soaking net shell, then place the seeds on the upper surface of the bottom plate, and then loosen the bottom plate so that the bottom plate is closed under the resetting action of the compression spring;

[0023] Step 3: Start the motor to drive the spline shaft and the external threaded tube to rotate synchronously counterclockwise. Under the cooperation of the external threaded tube and the internal threaded sleeve, the external threaded tube moves downward, thereby driving the seed soaking net shell to move downward and sink into the seed soaking liquid in the liquid storage tank. The soaking time is 4-6 hours;

[0024] Step 4: Then start the motor to drive the spline shaft and the external threaded tube to rotate synchronously clockwise. Under the cooperation of the external threaded tube and the internal threaded sleeve, the external threaded tube moves upward, thereby driving the seed soaking net shell to move upward into the fixed shell. Then the flip plate and the box cover are automatically closed under the action of the reset hinge, and the T-shaped slide bar squeezes the touch switch to start the water pump and stop the motor at the same time. The water pump supplies water to the L-shaped elbow, and the nozzle sprays water to wash the seeds inside the seed soaking net shell;

[0025] Step 5: Then put a cloth bag on the output end of the water outlet pipe, continue to start the motor to drive the spline shaft and the external threaded tube to rotate synchronously clockwise, and the seed soaking net shell moves upward to squeeze the lower pressure rod. At this time, the bottom plate will not move upward, so that there is a gap between the seed soaking net shell and the bottom plate. The upward movement of the seed soaking net shell causes the constraint plate to move upward, changing the deflection constraint direction of the rotating plate. Then the rotation of the external threaded tube will drive the internal threaded sleeve to rotate idly, that is, the seed soaking net shell rotates, and cooperates with the work of the sprinkler head to make the seeds in the seed soaking net shell be discharged from the water outlet pipe along the water flow and collected by the cloth bag, and then the cloth bag is placed in an environment of 25-30℃ for germination.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] In the present invention, by arranging a motor, a spline shaft, an externally threaded tube, an internally threaded sleeve, a bevel gear disk and a limiter, on the one hand, the externally threaded tube can be rotated counterclockwise and move downward, so that the seed soaking net shell sinks into the seed soaking liquid in the liquid storage tank, and the continued rotation of the externally threaded tube will drive the internally threaded sleeve to rotate idly, so that the seed soaking net shell rotates counterclockwise inside the liquid storage tank, thereby increasing the repeated contact between the seeds and the seed soaking liquid, and on the other hand, the externally threaded tube can be rotated clockwise and move upward, so that the seed soaking net shell is lifted into the fixed shell, and the continued rotation of the externally threaded tube will drive the internally threaded sleeve to rotate idly, so that the seed soaking net shell rotates clockwise inside the fixed shell, thereby enabling the flushing component to fully flush the seeds in the seed soaking net shell.

[0028] In the present invention, by arranging an L-shaped elbow and a nozzle, it is convenient to fully rinse the seeds in the seed soaking net shell, and with the cooperation of the T-shaped slide bar and the touch-pressure switch, the water pump is automatically started, and with the cooperation of the T-shaped slide bar and the spline shaft, a gap will be created between the seed soaking net shell and the bottom plate during the upward movement of the seed soaking net shell, so that the seeds are discharged smoothly with the water flow, avoiding the seeds from being wet and adhering to the inner wall of the seed soaking net shell, making it difficult for workers to recover them.

[0029] In the present invention, when the connecting spring is in the reset state, the bevel gear disk is restricted from rotating clockwise. At this time, the motor drives the spline shaft and the external threaded tube to rotate clockwise synchronously, which will cause the external threaded tube to drive the seed soaking net shell to move upward synchronously. Under the action of the compression rod under the squeezing of the seed soaking net shell, the constraint plate is driven to move upward, changing the constraint on the rotation direction of the rotating plate. The clockwise rotation of the motor will drive the spline shaft, the external threaded tube and the internal threaded sleeve to rotate clockwise synchronously, so that the seed soaking net shell rotates in the fixed shell.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1-Figure 9 As shown, an eggplant seedling raising device comprises a cultivation box 1, a liquid storage tank 5 is provided on the bottom surface of the cultivation box 1, a fixed shell 6 is provided inside the cultivation box 1, and two flip plates 15 for closing the lower end of the fixed shell 6 are symmetrically hinged at the lower end of the fixed shell 6 through a reset hinge, and the fixed shell 6 is fixedly connected to the inner wall of the cultivation box 1 through a support rod 8, and a spline shaft 13 is rotatably provided on the top surface of the cultivation box 1, and a motor 4 for driving the spline shaft 13 to rotate is provided at the upper end of the cultivation box 1, and an externally threaded tube 7 is slidably sleeved at the lower end of the spline shaft 13, and the lower end of the externally threaded tube 7 movably passes through the middle part of the upper end of the fixed shell 6 and is provided with a storage component, and a connecting component matching the externally threaded tube 7 is provided at the middle part of the upper end of the fixed shell 6, and a flushing component for flushing seeds is provided inside the fixed shell 6;

[0042] The storage component includes a seed soaking net shell 26 fixed to the lower end of the external threaded tube 7 and a T-shaped slide bar 28 movably penetrating the inner bottom surface of the external threaded tube 7. The T-shaped slide bar 28 is connected to the inner bottom surface of the external threaded tube 7 by a compression spring 27. The lower end of the T-shaped slide bar 28 is provided with a bottom plate 29 for closing the lower end of the seed soaking net shell 26. A take-in and put-out port is provided on one side of the incubator 1, and a sealing door 3 is hingedly provided inside the take-in and put-out port. When in use, the staff opens the sealing door 3, controls the height of the seed soaking net shell 26 by the motor 4, and then pulls the bottom plate 29 downward to place the selected seeds on the bottom plate 29, and then releases the bottom plate 29, so that the bottom plate 29 abuts against the lower end surface of the seed soaking net shell 26 under the action of the compression spring 27 returning to the original position, that is, the lower end of the seed soaking net shell 26 is closed, so that the seeds are in the closed shell.

[0043] Furthermore, the connecting assembly includes an internally threaded sleeve 19 threadably matched with the externally threaded tube 7 and a bevel gear 18 fixedly sleeved at the lower end of the internally threaded sleeve 19. The upper end of the internally threaded sleeve 19 is rotatably connected to the fixed shell 6 through a bearing 20. An installation groove is provided on the inner top surface of the fixed shell 6. A limit member for limiting the rotation of the internally threaded sleeve 19 and matching with the bevel gear 18 is provided inside the installation groove. The limit member is used to limit the rotation direction of the bevel gear 18, that is, to limit the rotation direction of the internally threaded sleeve 19.

[0044] Furthermore, the flushing component includes an L-shaped elbow 32 fixed on the inner wall of the fixed shell 6 and a water inlet pipe 14 penetrating the side wall of the fixed shell 6. A water pump is provided on the outside of the incubator 1. One end of the water inlet pipe 14 is connected to the L-shaped elbow 32, and the other end of the water inlet pipe 14 passes through the outside of the incubator 1 and is connected to the water pump. A plurality of nozzles for flushing the seed soaking net shell 26 are provided on the surface of the L-shaped elbow 32. A water outlet pipe 16 is penetrated on the other side of the fixed shell 6. The water outlet pipe 16 and the L-shaped elbow 32 are arranged opposite to each other, so that the water flow can flush the seeds to the water outlet pipe 16. A drain pipe 31 is provided at the lower end of one side of the incubator 1. The water pump supplies water to the water inlet pipe 14 and the L-shaped elbow 32, so that water is sprayed out through the nozzle. On the one hand, it is used to flush the seeds, and on the other hand, the seeds can be discharged along with the water flow, which is convenient for the staff to recover.

[0045] Furthermore, the limiting member includes a rotating plate 21 rotatably arranged inside the mounting groove and a restraining plate 23 slidably arranged inside the mounting groove for restraining the rotating direction of the rotating plate 21. The upper end of the restraining plate 23 is connected to the top surface of the mounting groove by a connecting spring 25. A magnet 33 for adsorbing the restraining plate 23 is fixedly arranged on the top surface of the mounting groove. A notch groove matching the magnet 33 is opened on the surface of the rotating plate 21. A lower pressure rod 17 matching the upper end surface of the seed soaking net shell 26 is fixedly arranged at the lower end of the restraining plate 23. An upper pressure rod 22 is fixedly arranged at the upper end of the restraining plate 23. A fixing disk 9 for squeezing the upper pressure rod 22 is sleeved on the upper end of the externally threaded tube 7. A tooth block 24 matching the conical tooth disk 18 is arranged at the lower end of the rotating plate 21. When the restraining plate 23 is located at the lower end of one side of the rotating plate 21, it is located below the rotating shaft of the rotating plate 21 (refer to the attached manual). Figure 4 With the instruction manual Figure 5 ), because the clockwise rotation of the bevel gear disc 18 is restricted by the tooth block 24, when the motor 4 drives the spline shaft 13 and the external threaded tube 7 to rotate synchronously clockwise, the external threaded tube 7 will rotate and move upward, so that the seed soaking net shell 26 is lifted to the inside of the fixed shell 6, and then the two flip plates 15 are automatically closed under the action of the reset hinge, and the lower end of the fixed shell 6 is sealed. As the seed soaking net shell 26 continues to move upward, the lower pressure rod 17 will be squeezed, so that the constraint plate 23 moves upward, and the constraint plate 23 is adsorbed and fixed to the magnet 33. The adsorption force of the magnet 33 on the constraint plate 23 is greater than the elastic force of the connecting spring 25 in the compressed state, thereby changing the restriction direction of the rotating plate 21. That is, the clockwise rotation restriction of the bevel gear disk 18 is released, and the counterclockwise rotation of the bevel gear disk 18 is restricted at this time, preparing for the subsequent downward movement of the seed soaking net shell 26. When the clockwise rotation restriction of the bevel gear disk 18 is released, the external threaded tube 7 will drive the seed soaking net shell 26 and the internal threaded sleeve 19 to rotate synchronously. At this time, the clockwise rotation of the motor 4 will not drive the external threaded tube 7 to continue to move upward. On the contrary, when the motor 4 rotates counterclockwise, the counterclockwise rotation of the bevel gear disk 18 is restricted. When the motor 4 drives the spline shaft 13 and the external threaded tube 7 to rotate synchronously counterclockwise, the external threaded tube 7 will rotate and move downward at the same time, so that the seed soaking net shell 26 sinks into the seed soaking liquid inside the liquid storage tank 5.

[0046] Furthermore, two box covers 12 are symmetrically hinged at the upper end of the liquid storage tank 5 through a reset hinge, a liquid inlet pipe 11 is penetrated through the upper end of one side of the liquid storage tank 5, and a liquid discharge pipe 10 is penetrated through the lower end of one side of the liquid storage tank 5. One end of the liquid inlet pipe 11 and the liquid discharge pipe 10 both pass through the outside of the cultivation box 1 and are provided with valves. When the seed soaking net shell 26 is lifted to the top of the liquid storage tank 5, the two box covers 12 will automatically close under the action of the reset hinge, effectively preventing the water flushed by the flushing component from flowing into the liquid storage tank 5.

[0047] Furthermore, a controller 30 is fixedly provided on the outside of the incubator 1, the water pump is electrically connected to the controller 30, a touch-pressure switch 34 is fixedly embedded at the lower end of the spline shaft 13, the touch-pressure switch 34 is electrically connected to the controller 30, and the motor 4 is electrically connected to the controller 30. When the T-shaped slide bar 28 squeezes the touch-pressure switch 34, the water pump will automatically start to complete the work of flushing the seeds in the seed soaking net shell 26.

[0048] Furthermore, a transparent window 2 is embedded on the surface of the cultivation box 1. The material of the transparent window 2 is acrylic. The liquid storage tank 5 is made of a transparent material, which is convenient for the staff to observe the soaking and cultivation status of the seeds.

[0049] An eggplant seed cultivation method using an eggplant seedling raising device comprises the following steps:

[0050] Step 1: Select high-quality seeds by observing the color and fullness of eggplant seeds;

[0051] Step 2: Put the selected seeds into the storage assembly, that is, pull the bottom plate 29 downward so that there is a gap between the bottom plate 29 and the lower end surface of the seed soaking net shell 26, then place the seeds on the upper surface of the bottom plate 29, and then loosen the bottom plate 29 so that the bottom plate 29 is closed under the resetting action of the compression spring 27;

[0052] Step 3: Start the motor 4 to drive the spline shaft 13 and the external threaded tube 7 to rotate synchronously counterclockwise. Under the cooperation of the external threaded tube 7 and the internal threaded sleeve 19, the external threaded tube 7 moves downward, thereby driving the seed soaking net shell 26 to move downward and sink into the seed soaking liquid in the liquid storage tank 5. The soaking time is 4-6 hours;

[0053] Step 4: Then start the motor 4 to drive the spline shaft 13 and the externally threaded tube 7 to rotate synchronously clockwise. Under the cooperation of the externally threaded tube 7 and the internally threaded sleeve 19, the externally threaded tube 7 moves upward, thereby driving the seed soaking net shell 26 to move upward into the fixed shell 6. Then the flip plate 15 and the box cover 12 are automatically closed under the action of the reset hinge, and the T-shaped slide bar 28 squeezes the touch switch 34, so that the water pump starts and the motor 4 stops working at the same time. The water pump supplies water to the L-shaped elbow 32, and the nozzle sprays water to wash the seeds inside the seed soaking net shell 26;

[0054] Step 5: Then put a cloth bag on the output end of the water outlet pipe 16, continue to start the motor 4 to drive the spline shaft 13 and the external threaded tube 7 to rotate synchronously clockwise, and the seed soaking net shell 26 moves upward to squeeze the lower pressure rod 17. At this time, the bottom plate 29 will not move upward, so that there is a gap between the seed soaking net shell 26 and the bottom plate 29. The upward movement of the seed soaking net shell 26 causes the constraint plate 23 to move upward, changing the deflection constraint direction of the rotating plate 21, and then the rotation of the external threaded tube 7 will drive the internal threaded sleeve 19 to idle, that is, the seed soaking net shell 26 is rotated, and cooperates with the work of the nozzle, so that the seeds in the seed soaking net shell 26 are discharged from the water outlet pipe 16 along the water flow and collected by the cloth bag, and then the cloth bag is placed in an environment of 25-30℃ for germination.

The eggplant seed cultivation method according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: Select high-quality seeds by observing the color and fullness of eggplant seeds; Step 2: placing the selected seeds into the storage assembly, that is, pulling the bottom plate (29) downward so that there is a gap between the bottom plate (29) and the lower end surface of the seed soaking net shell (26), and then placing the seeds on the upper surface of the bottom plate (29), and then loosening the bottom plate (29) so that the bottom plate (29) is closed under the resetting action of the compression spring (27); Step 3: Start the motor (4) to drive the spline shaft (13) and the externally threaded tube (7) to rotate synchronously counterclockwise, and under the cooperation of the externally threaded tube (7) and the internally threaded sleeve (19), the externally threaded tube (7) moves downward, thereby driving the seed soaking net shell (26) to move downward and sink into the seed soaking liquid in the liquid storage tank (5), and the soaking time is 4-6 hours; Step 4: Then start the motor (4) to drive the spline shaft (13) and the externally threaded tube (7) to rotate synchronously clockwise, and under the cooperation of the externally threaded tube (7) and the internally threaded sleeve (19), the externally threaded tube (7) moves upward, thereby driving the seed soaking net shell (26) to move upward into the fixed shell (6), and then the flip plate (15) and the box cover (12) are automatically closed under the action of the reset hinge, and the T-shaped slide bar (28) squeezes the touch switch (34), so that the water pump starts and the motor (4) stops working at the same time, and the water pump supplies water to the L-shaped elbow (32), and the nozzle sprays water to wash the seeds inside the seed soaking net shell (26); Step 5: Then put a cloth bag on the output end of the water outlet pipe (16), continue to start the motor (4) to drive the spline shaft (13) and the external threaded tube (7) to rotate synchronously clockwise, the seed soaking net shell (26) moves upward to squeeze the lower pressure rod (17), and the bottom plate (29) does not move upward at this time, so that there is a gap between the seed soaking net shell (26) and the bottom plate (29). The upward movement of the seed soaking net shell (26) causes the constraint plate (23) to move upward, changing the deflection constraint direction of the rotating plate (21), and then the rotation of the external threaded tube (7) will drive the internal threaded sleeve (19) to rotate, that is, the seed soaking net shell (26) rotates, and cooperates with the work of the nozzle, so that the seeds in the seed soaking net shell (26) are discharged from the water outlet pipe (16) along the water flow and collected by the cloth bag, and then the cloth bag is placed in an environment of 25-30°C for germination.
