Technical Field
[0001] This utility model relates to the field of rice seedling cultivation technology, specifically a rice seedling cultivation device that facilitates the removal of seedlings. Background Technology
[0002] Rice seedling raising is a crucial step in rice cultivation. Existing seedling raising devices mostly use integrated seedling trays, which present the following problems:
[0003] Difficulty in removing seedlings: The roots of the seedlings are stuck to the inner wall of the seedling tray, and they need to be forcibly separated when removing the seedlings, which can easily damage the roots and reduce the survival rate of the seedlings.
[0004] Inconvenient management: The integrated structure makes it impossible to remove individual seedlings or parts of the seedlings, making replanting and thinning operations cumbersome. Utility Model Content
[0005] The purpose of this invention is to provide a rice seedling cultivation device that facilitates the removal of seedlings, thereby solving the problems mentioned in the background art.
[0006] The technical solution of this utility model is: a rice seedling cultivation device that facilitates the removal of seedlings, including a movable base, a shelf installed on the movable base, and multiple seedling cultivation components distributed vertically on the shelf. Each seedling cultivation component includes a seedling tray, a seedling plate provided at the top of the seedling tray, and seedling cavities arranged in an array on the seedling plate. A push-out component located at the bottom of the seedling cavity is slidably inserted into the bottom of the seedling tray.
[0007] The effects achieved by the above components are as follows: the movable base provides a movable foundation for the entire device, facilitating the overall transfer of the cultivation device to a suitable light and temperature environment for seedling cultivation; the shelf, through its vertically distributed structure, supports multiple seedling components in layers, expanding the seedling space vertically; within the seedling components, the array of seedling chambers on the seedling plate enables independent cultivation of single or partial seedlings, avoiding the interference caused by traditional integrated seedling trays, while the ejector component applies an upward force to the seedlings from the bottom of the seedling chamber, facilitating the removal of single or partial seedlings. This not only solves the problem of root damage when removing seedlings from integrated seedling trays but also enhances the environmental adaptability of the device (allowing for flexible transfer to suitable cultivation areas).
[0008] Preferably, the ejection assembly includes a push rod that slides into the bottom of the seedling tray, and an ejection block located at the bottom of the seedling cavity is fixed to the top of the push rod.
[0009] The effect achieved by the above components is as follows: the push rod is slidably inserted into the bottom of the seedling tray, and the ejector block fixed at its top is located at the bottom of the seedling cavity. When it is necessary to remove the seedling, the push rod is pushed inward to the seedling tray. The push rod drives the ejector block to slide upward along the inner wall of the seedling cavity. The ejector block directly acts on the area below the roots of the seedling in the seedling cavity, pushing the seedling out of the seedling cavity. This method replaces the traditional method of "forcibly separating the seedling from the seedling tray" and achieves the goal of "removing the seedling without damage", effectively reducing the damage to the root system of the seedling during the seedling removal process.
[0010] Preferably, a protruding ring is fixed at the top of the push rod, a return spring is provided above the protruding ring and sleeved outside the ejector block and in contact with the bottom of the seedling tray, and a support spring is provided at the bottom of the protruding ring and sleeved outside the push rod.
[0011] The aforementioned components achieve the following effects: when removing seedlings, pushing the push rod causes the convex ring to move synchronously, compressing the support spring and stretching the return spring, thus completing the seedling removal action of the ejector block; after removing the seedlings, releasing the push rod causes the return spring to push the convex ring upwards, and the return spring of the support spring assists in the return of the convex ring, thereby causing the push rod and ejector block to return to their initial positions (the ejector block is in contact with the bottom of the seedling cavity); this coordination achieves the purpose of "automatic reset of the ejector component", eliminating the need for manual adjustment of the positions of the push rod and ejector block, reducing the operation steps after removing seedlings, and improving the efficiency of seedling removal.
[0012] Preferably, the top edge of the ejector block has multiple annularly distributed guide slits, and the bottom of the seedling tray has guide holes.
[0013] The effect achieved by the above components is as follows: when watering, excess water collects in the seedling cavity, and the annular guide slant at the top of the ejector block can guide the water to flow to the bottom edge of the seedling cavity, avoiding water accumulation under the roots of the seedlings. At the same time, the flowing water is discharged to the outside of the device through the guide holes at the bottom of the seedling tray. This combination solves the problem of "unreasonable drainage hole design leading to water accumulation and root rot or excessive water loss" in traditional seedling trays, and achieves the purpose of "precise drainage and avoidance of water accumulation".
[0014] Preferably, the shelf includes a support rod fixed at the top corner of the movable seat, and the support rod has grooves fixed on it for supporting the edge of the seedling tray.
[0015] The aforementioned components achieve the following effects: the support rod is fixed at the top corner of the movable base, providing a stable support structure for the shelf and preventing deformation due to the load of multiple seedling components; the groove on the support rod matches the edge of the seedling tray, allowing the seedling tray to be placed directly on the groove for fixation, and disassembly only requires pushing the seedling tray laterally to detach it from the groove; this fit replaces the traditional method of "fixed connection between seedling tray and shelf", achieving the goal of "convenient disassembly and assembly of seedling components", facilitating individual cleaning, replacement, or transportation of the seedling tray.
[0016] This utility model provides an improved rice seedling cultivation device that facilitates the removal of seedlings, and compared with the prior art, it has the following improvements and advantages:
[0017] Firstly, this utility model enables the independent cultivation of single or partial seedlings through the array of seedling chambers on the seedling plate, avoiding the interference of traditional integrated seedling trays. At the same time, the ejector component can apply an upward force to the seedlings from the bottom of the seedling chamber, making it easy to remove single or partial seedlings. This not only solves the problem of root damage when removing seedlings from integrated seedling trays, but also enhances the environmental adaptability of the device.
[0018] Secondly, when seedlings need to be removed, the present invention pushes the push rod inside the seedling tray. The push rod drives the ejector block to slide upward along the inner wall of the seedling cavity. The ejector block directly acts on the area below the roots of the seedlings in the seedling cavity, pushing the seedlings out of the seedling cavity. This replaces the traditional method of "forcibly separating the seedlings from the seedling tray" and achieves the goal of "removing seedlings without damage". Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.
[0026] This utility model provides an improved rice seedling cultivation device that facilitates the removal of seedlings. The technical solution of this utility model is as follows:
[0027] In embodiments of this utility model, such as Figures 1-3 As shown, a rice seedling cultivation device for easy removal of seedlings includes a movable base 1, on which a shelf 2 is mounted. The shelf 2 includes a support rod fixed at the top corner of the movable base 1. A groove is fixed on the support rod to support the edge of a seedling tray 31. The groove on the support rod is adapted to the edge of the seedling tray 31, allowing the seedling tray 31 to be directly placed on the groove for fixation. Disassembly only requires a horizontal push of the seedling tray 31 to detach it from the groove. Multiple vertically distributed seedling components 3 are mounted on the shelf 2. Component 3 includes a seedling tray 31, a seedling plate 32 is provided at the top of the seedling tray 31, and seedling cavities 33 are arranged in an array on the seedling plate 32. A push-out component 5 is slidably inserted into the bottom of the seedling tray 31 and located at the bottom of the seedling cavity 33. In the seedling component 3, the array of seedling cavities 33 on the seedling plate 32 realizes the independent cultivation of single seedlings or partial seedlings, avoiding the interference of the traditional integral seedling tray. At the same time, the push-out component 5 can apply an upward force to the seedlings from the bottom of the seedling cavity 33, making it easy to remove single seedlings or partial seedlings individually.
[0028] In this embodiment of the invention, the ejector assembly 5 includes a push rod 51 slidably inserted into the bottom of the seedling tray 31. An ejector block 52 located at the bottom of the seedling cavity 33 is fixed to the top of the push rod 51. When seedlings need to be removed, the push rod 51 is pushed inwards towards the seedling tray 31. The push rod 51 causes the ejector block 52 to slide upwards along the inner wall of the seedling cavity 33. The ejector block 52 directly acts below the roots of the seedlings in the seedling cavity 33, ejecting the seedlings from the seedling cavity 33. A protruding ring 53 is fixed to the top of the push rod 51. A return spring 54, sleeved on the outside of the ejector block 52 and contacting the bottom of the seedling tray 31, is provided above the protruding ring 53. A support spring 55, sleeved on the outside of the push rod 51, is provided at the bottom of the protruding ring 53. When removing seedlings, pushing the push rod 51 causes the protruding ring 53 to move synchronously. The support spring 55 is compressed and the reset spring 54 is stretched, and the ejector block 52 completes the seedling ejection action. After the seedling is taken out, the push rod 51 is released, and the rebound force of the reset spring 54 drives the convex ring 53 to reset upward. The rebound force of the support spring 55 assists the convex ring 53 to reset, thereby causing the push rod 51 and the ejector block 52 to return to their initial positions. The top edge of the ejector block 52 is provided with multiple annularly distributed guide sloping openings 56, and the bottom of the seedling tray 31 is provided with guide holes 4. When watering, excess water collects in the seedling cavity 33. The annular guide sloping openings 56 at the top of the ejector block 52 can guide the water to flow to the bottom edge of the seedling cavity 33, avoiding water accumulation below the roots of the seedlings. At the same time, the flowing water is discharged to the outside of the device through the guide holes 4 at the bottom of the seedling tray 31.
[0029] The working principle of the rice seedling cultivation device that facilitates the removal of seedlings provided by this utility model is as follows: Device positioning and assembly: The device is moved as a whole through the movable seat 1 and transferred to a suitable seedling environment such as a sunny place or a greenhouse. Then, the support rod of the shelf 2 is used in conjunction with the groove to slide the edge of the seedling tray 31 of the seedling component 3 onto the groove, thereby completing the rapid assembly of the multi-layer seedling component 3 and realizing the vertical space seedling layout.
[0030] Soil filling and sowing: Fill the array of seedling chambers 33 of the seedling plate 32 in the seedling component 3 with rice seedling soil, sow 1-2 rice seeds in each chamber and cover with fine soil. The independent seedling chambers 33 are used to achieve isolated cultivation of single / local seedlings to avoid interference when taking seedlings later.
[0031] Drainage during cultivation: When watering, excess water collects in the seedling cavity 33 and is guided to the bottom edge of the seedling cavity 33 through the annular guide oblique opening 56 at the top of the ejector block 52 in the ejector component 5. Finally, it is discharged through the guide hole 4 at the bottom of the seedling tray 31 to prevent water accumulation from causing seedling root rot, while maintaining suitable humidity in the seedling cavity 33.
[0032] Seedling removal and component reset: When the seedlings have grown to the 3-4 leaf stage and need to be removed, push the push rod 51 of the ejector component 5 towards the inside of the seedling tray 31. The push rod 51 drives the ejector block 52 to move upward along the inner wall of the seedling cavity 33. The ejector block 52 directly pushes the root of the seedling, removing the seedling from the seedling cavity 33 (during this process, the convex ring 53 at the top of the push rod 51 compresses the support spring 55 and stretches the reset spring 54). After removing the seedling, release the push rod 51. The return of the reset spring 54 and the return of the support spring 55 work together on the convex ring 53, driving the push rod 51 and the ejector block 52 back to their initial positions (the ejector block 52 fits against the bottom of the seedling cavity 33) for the next use.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
