Description

Technical Field

[0001] This invention relates to the field of seedling raising device technology, specifically a seedling raising device for agricultural technology promotion. Background Technology

[0002] Seedling raising is a crucial step in agricultural production, and high-quality seedling raising technology lays a solid foundation for high and stable crop yields. In the process of agricultural technology promotion, seedling raising devices serve as important carriers for showcasing modern agricultural scientific and technological achievements; their structural design, functional integration, and ease of operation directly affect the promotion effect. However, existing seedling raising devices have many shortcomings in practical applications, failing to meet the multiple demands of agricultural technology promotion scenarios regarding space utilization, light uniformity, management convenience, and protective functions.

[0003] Existing seedling cultivation devices mostly adopt a single-layer planar structure, that is, seedling beds are laid out on the ground or seedling trays are placed for cultivation. Although this type of structure is simple to operate, it has prominent problems such as large footprint and low space utilization. At agricultural technology extension sites, the limited display space often cannot accommodate large-area planar seedling cultivation facilities, resulting in a limited variety and quantity of displayed varieties, making it difficult to fully demonstrate the advantages of modern agriculture in terms of scale and intensification. In addition, seedlings in a single-layer planar structure are on the same horizontal plane. Affected by changes in the angle of natural light, the light intensity and duration received by seedlings in different areas vary significantly, which can easily lead to uneven seedling growth and inconsistent quality, affecting the uniformity and professionalism of the display effect.

[0004] Furthermore, agricultural technology extension sites are typically located in open or semi-open environments, making it easy for insects to come into contact with and damage seedlings. Outdoor birds also pose a risk. Existing seedling cultivation facilities lack effective physical pest control measures and rely heavily on chemical pesticides, which contradicts the concepts of green agriculture and ecological demonstration. Additionally, pesticide residues may negatively impact the experience and health of on-site personnel.

[0005] Therefore, we have launched a seedling raising device for agricultural technology promotion. Summary of the Invention

[0006] The purpose of this invention is to provide a seedling raising device for agricultural technology promotion, thereby solving the problems mentioned in the background above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a seedling raising device for agricultural technology promotion, comprising a column, a top cover connected to the upper end of the column, cultivation components installed at intervals on the outside of the column, a protective component and a base component provided at the lower end of the column, the protective component being located above the base component, and actuating plates symmetrically arranged on the outside of the lower end of the column;

[0008] A threaded column is fixedly installed at the middle of the upper end of the column. Guide grooves are spaced apart on the outer surface of the column. Limiting grooves are symmetrically opened on the inner walls of both sides of the guide grooves. Fixing holes are vertically spaced apart on the inner wall of the guide grooves near the center of the column.

[0009] The cultivation component includes a cultivation tray and a groove on the upper surface of the cultivation tray. The bottom surface of the groove is provided with slots at intervals. A planting basket is movably inserted into the inner side of the slot. A positioning groove is provided on the side of the cultivation tray away from the column.

[0010] The cultivation tray has guide blocks symmetrically welded at both ends on the side closest to the column. Limiting sliders are symmetrically installed on both sides of the guide blocks, and a connecting hole is opened in the middle of the guide blocks.

[0011] Furthermore, a threaded sleeve is fixedly provided at the center of the lower end of the top cover, and light sources are spaced apart on the lower surface of the top cover. A power module is provided on one side of each light source, and the light source and the power module are electrically connected.

[0012] Furthermore, the culture trays are divided into four groups, and each group of culture trays has a fan-shaped structure.

[0013] Furthermore, a baffle is fixedly installed on the upper outer wall of the planting basket, and drainage holes are spaced apart on the lower outer wall of the planting basket.

[0014] Furthermore, a fixing iron plate is fixedly installed on the inner wall of the positioning groove near the guide block, and a water collection tray is interlocked inside the positioning groove. A magnetic suction plate is fixedly installed at one end of the water collection tray, and a pull rod is installed in the middle of the other end of the water collection tray.

[0015] Furthermore, the protective assembly includes a protective cover and a bearing installed in the middle of the upper end of the protective cover. Lugs A are welded at intervals on the outer wall of the lower end of the protective cover. Support legs are installed at intervals on the outer wall of the protective cover, and rollers are installed at the lower ends of the support legs.

[0016] Furthermore, connecting ropes are installed at intervals on the upper end of the inner cavity of the protective cover, and hollow hammers are installed on the lower end of the connecting ropes.

[0017] Furthermore, the base assembly includes a counterweight base and a drive motor mounted in the middle of the upper end of the counterweight base. A battery box is mounted on one side of the drive motor. A circular baffle is mounted on the outside of the drive motor and the battery box. The circular baffle is fixed to the upper end of the counterweight base.

[0018] Furthermore, the counterweight base is made of metal or high-density concrete in a hemispherical structure, and the bottom center of the counterweight base is a solid iron structure.

[0019] Furthermore, lugs B are welded at intervals on the outer wall of the upper end of the counterweight base, and hollow tubes in an annular array are installed at intervals on the upper end of the counterweight base, with the hollow tubes located around the circular baffle.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention employs a modular design where four sets of 90-degree fan-shaped cultivation trays are assembled around a column to form a complete circular cultivation layer. Each cultivation tray is embedded in a guide groove in the column via a guide block, and with the mortise and tenon joint between the limiting slider and the limiting groove, the cultivation tray can be independently raised and lowered along the column axis. Operators can adjust the four sets of cultivation trays to form a spiral, stepped layout according to the crop type, growth stage, and on-site lighting conditions, ensuring that seedlings at each level receive direct sunlight and completely eliminating the shading problem of traditional fixed multi-layer racks. Simultaneously, each cultivation tray is equipped with a light source and power module identical to the top cover, which can be activated for supplemental lighting in cloudy or rainy weather or indoor environments, simulating natural light cycles to further ensure uniform lighting. This design is suitable for limited display spaces in agricultural technology extension sites, allowing for the display of more varieties and larger quantities of seedlings without increasing the floor space, fully reflecting the intensive and efficient characteristics of modern agriculture.

[0022] 2. This invention features a groove on the upper surface of the cultivation tray to temporarily store overflowing irrigation water or nutrient solution. Slots are spaced at intervals on the bottom of the groove for inserting planting baskets. Drainage holes spaced at intervals on the lower outer wall of the planting baskets ensure excess water seeps out from the substrate inside the basket while effectively preventing significant loss of substrate particles. A water collection tray is interlocked inside the positioning groove to collect irrigation water or nutrient solution seeping from the drainage holes. A magnetic plate is fixedly installed at one end of the water collection tray, forming a magnetic attraction with a fixed iron plate on the inner wall of the positioning groove. This ensures the water collection tray does not fall off or shift during the rotation of the column and allows the operator to easily pull it outwards by gripping the pull rod to overcome the magnetic attraction for cleaning. This magnetic quick-release structure allows for tool-free cleaning, which can be completed with one hand, significantly improving management convenience.

[0023] 3. This invention uses a drive motor in the base assembly to rotate the column 1 and the cultivation components around a central axis at a uniform speed, allowing the seedlings on each cultivation tray to face the audience sequentially, achieving a 360-degree dynamic display and significantly enhancing the interactivity and visual appeal of agricultural technology promotion. Furthermore, symmetrically installed actuating plates at the lower end of the column rotate synchronously with the column, continuously pushing the hollow hammer at the lower end of the connecting rope inside the protective cover to swing and shift during rotation. The hollow hammer, made of plastic or rubber, is a hollow sphere or ellipsoid located between the circular baffle and the annular array of hollow tubes. Its swinging motion, touching the hollow tubes, generates slight vibrations and sounds, creating a continuous physical repulsion signal that effectively drives away insects and birds attempting to stay near the protective cover or cultivation trays. This mechanism relies entirely on mechanical movement to produce an insect-repelling effect, requiring no chemical pesticides, and is highly consistent with the concept of green agricultural demonstration.

[0024] 4. The counterweight base of this invention is made of metal or high-density concrete in a hemispherical structure, with a solid iron core at the bottom, forming a low center of gravity design similar to a roly-poly toy. When the device is tilted by an external force, the hemispherical surface contacts the ground first, providing a fulcrum and generating a restoring torque that automatically returns the device to an upright position, fundamentally avoiding the risk of complete tipping over. This design is particularly suitable for uneven ground environments in outdoor agricultural technology promotion sites. Meanwhile, rollers are installed at the lower ends of the support legs spaced apart on the outer wall of the protective cover. In the normal vertical state, the rollers are away from the ground and directly supported by the counterweight base, ensuring absolute stability during demonstrations. When relocation is required, the operator tilts the device so that the rollers touch the ground, allowing for easy movement. After positioning, the device is restored to an upright state, lifting the rollers off the ground and re-entering a stable support mode, further reducing the risk of the entire device tipping over.

[0038] 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.

[0039] Example 1:

[0040] Please see Figure 1-11A seedling raising device for agricultural technology promotion includes a column 1, which serves as the central support frame of the entire device and adopts a hollow round tube structure to reduce the overall weight. A top cover 2 is connected to the upper end of the column 1, and cultivation components 3 are installed at intervals on the outside of the column 1. A protective component 4 and a base component 5 are provided at the lower end of the column 1, with the protective component 4 located above the base component 5.

[0041] A threaded post 11 is fixedly installed at the middle of the upper end of the column 1. The threaded post 11 is integrally formed or welded to the column 1. Four guide grooves 12 are evenly opened along the axial direction on the outer surface of the column 1. The four guide grooves 12 are symmetrically distributed in a cross shape to ensure that the subsequent cultivation components 3 are evenly distributed around the column 1. Limiting grooves 13 are symmetrically opened on the inner walls on both sides of the guide grooves 12. The cross-section of the limiting grooves 13 is T-shaped or dovetail-shaped. Fixing holes 14 are vertically spaced on the inner wall of the guide grooves 12 near the center of the column 1. The spacing between adjacent fixing holes 14 is set according to the light layer spacing required for common crop seedling cultivation, for example, it can be set to 150mm, 200mm or 250mm.

[0042] The top cover 2 is made of ABS plastic or aluminum alloy, with a diameter 3-5 times the outer diameter of the column 1. A threaded sleeve 21 is fixedly installed at the center of the lower end of the top cover 2. The top cover 2 is threadedly connected and fixed to the top of the column 1 through the threaded sleeve 21. The diameter of the top cover 2 is larger than the outer diameter of the column 1, and its outer edge extends downward to form an eave, which is used to block rain and excessive sunlight, protecting the seedlings in the top cultivation component 3. Light sources 22 are spaced apart on the lower surface of the top cover 2. A power module 23 is installed on one side of the light source 22. The light source 22 is an LED plant growth light. The power module 23 includes an LED driver, a timer controller, and a light intensity regulator. The input voltage is AC220V or DC24V, and the output power matches the total power of the light source 22 (usually 20-100W). It is connected to the light source 22 in series or parallel through a waterproof wire. The power module 23 can be set with an automatic timer function to simulate the natural light cycle (such as 14-16 hours of light per day). Existing technology will not be described in detail.

[0043] The cultivation component 3 includes a cultivation tray 31 and a groove 32 on the upper surface of the cultivation tray 31 for temporarily storing overflowing irrigation water or nutrient solution. The bottom surface of the groove 32 is provided with slots 33 at intervals. Multiple slots 33 are provided at intervals, and the number and diameter of the slots can be set as needed. A planting basket 34 is movably inserted into the inside of the slot 33. The diameter of the slot 33 matches the outer diameter of the planting basket 34. The planting basket 34 is movably inserted into the slot 33 from top to bottom. A positioning groove 35 is provided on the side of the cultivation tray 31 away from the column 1.

[0044] Guide blocks 311 are symmetrically welded to both ends of the cultivation tray 31 near the column 1. The thickness of the guide blocks 311 is adapted to the width of the guide groove 12, so that the guide blocks 311 can be embedded in the guide groove 12 and slide up and down along it. Limiting sliders 312 are symmetrically installed on both sides of the guide blocks 311. The limiting sliders 312 and the limiting groove 13 form a tenon-and-mortise sliding fit. The gap of this fit is controlled between 0.1-0.3mm, which not only ensures smooth sliding, but also prevents the cultivation tray 31 from shaking or radially dislodging during rotation. A connecting hole 313 is opened in the middle of the guide block 311. The connecting hole 313 in the middle of the guide block 311 is a through hole or a threaded hole. When the cultivation tray 31 is adjusted to the target height, the bolt passes through the connecting hole 313 and is tightened in the corresponding fixing hole 14 to realize the rigid connection between the cultivation tray 31 and the column 1.

[0045] The cultivation trays 31 are divided into four groups, and each group of cultivation trays 31 has a fan-shaped structure. When the four groups of cultivation trays 31 are assembled around the column 1, they will form a complete circular cultivation layer. Each group of cultivation trays 31 is equipped with a light source 22 and a power module 23 of the same type as the top cover 2, which can ensure that the light evenly covers each layer of cultivation trays 31 below.

[0046] A baffle 341 is fixedly installed on the upper outer wall of the planting basket 34. The planting basket 34 is made of plastic injection molding, and the upper outer wall is integrally formed with an annular baffle 341. The outer diameter of the baffle 341 is larger than the hole diameter of the slot 33. When the planting basket 34 is inserted into the slot 33, the baffle 341 rests on the upper surface of the slot 33 to prevent the planting basket 34 from sliding down to the bottom of the groove 32. The lower outer wall of the planting basket 34 is provided with drainage holes 342 at intervals. The hole diameter of the drainage holes 342 is set to 3-5mm, which ensures that excess water seeps out from the substrate in the basket into the groove 32, and prevents a large amount of substrate particles from being lost. The inside of the planting basket 34 can be filled with seedling substrate (such as a mixture of perlite, vermiculite and coconut coir). The seedling roots pass through the drainage holes 342 or extend from the bottom into the groove 32 below to absorb water and nutrients.

[0047] A fixing iron plate 351 is fixedly installed on the inner wall of the positioning groove 35 near the guide block 311. A water collection tray 352 is interlocked inside the positioning groove 35. A magnetic suction plate 353 is fixedly installed at one end of the water collection tray 352. A pull rod 354 is installed in the middle of the other end of the water collection tray 352. The opening of the positioning groove 35 is horizontally outward. The fixing iron plate 351 is fixedly installed on the inner wall of the positioning groove 35 near the guide block 311 by screws. The water collection tray 352 has a fan-shaped structure that matches the outer arc surface of the cultivation tray 31. The water collection tray 352 is horizontally inserted into the positioning groove 35 from the outside. After being pushed into place, the magnetic suction piece 353 magnetically adheres to the fixing iron piece 351, realizing the rapid fixation of the water collection tray 352. The magnetic suction piece 353 uses neodymium iron boron permanent magnets or ferrite magnets with a thickness of 2-3mm. The magnetic attraction force when the outer surface of the magnetic suction piece adheres to the fixing iron piece 351 is 5-15N, which can ensure that the water collection tray 352 does not fall off during rotation and is easy to pull out manually. The bottom of the water collection tray 352 is flush with or slightly lower than the bottom surface of the groove 32, so that excess water accumulated in the groove 32 can overflow or be guided to the water collection tray 352 for unified collection, preventing water from dripping directly onto the seedlings below and causing impact damage. When it is necessary to clean up the accumulated water, the operator can hold the lever 354 and pull it outward to overcome the magnetic attraction and pull the water collection tray 352 out of the positioning groove 35 for emptying and cleaning.

[0048] Example 2:

[0049] Please see Figure 1 , 9 -11, the protective component 4 includes a protective cover 41 and a bearing 42 embedded in the middle of the upper end of the protective cover 41. The protective cover 41 is made of transparent acrylic or polycarbonate and has a cylindrical structure. Its inner diameter is larger than the outer diameter of the culture tray 31 after assembly, thus forming an annular airflow buffer space between the protective cover 41 and the culture component 3. The bearing 42 is embedded in the middle of the upper end of the protective cover 41. The inner ring of the bearing 42 is interference-fitted or clearance-fitted with the outer circular surface of the column 1, and the outer ring is fixed to the protective cover 41, so that the column 1 can drive the culture component 3 and the top cover 2 to rotate. Lugs A43 are welded at intervals on the lower outer wall of the protective cover 41. Each lug A43 has an opening The protective cover 41 has holes, and the outer wall of the protective cover 41 is equipped with support legs 44 at intervals. The support legs 44 are made of aluminum alloy profiles or steel pipes and are evenly distributed around the outer wall of the protective cover 41. They are tilted outward at 15-30 degrees to form stable support. The lower end of the support legs 44 is equipped with rollers 45. The rollers 45 are universal wheels with brakes. When the device does not need to be moved, the entire device remains vertical and the rollers 45 will be away from the ground. When the device needs to be moved, the entire device can be tilted and the rollers 45 can be placed on the ground. Then the operator can push the entire device to move the device to a new position. After the device is in place, the rollers 45 are braked to stop, and the entire device can be pushed back to a vertical position.

[0050] The base assembly 5 includes a counterweight base 51 and a drive motor 52 mounted on the upper middle of the counterweight base 51. The upper middle of the counterweight base 51 has a motor mounting slot, and the drive motor 52 is fixed in the mounting slot by bolts. The output shaft of the drive motor 52 is coaxially connected to the lower end of the column 1 through a coupling or spline. A battery box 53 is installed on one side of the drive motor 52. A storage battery is detachably installed in the battery box 53. The battery box 53 is electrically connected to the drive motor 52 through a waterproof wire to provide DC power to the drive motor 52. The drive motor 52 can drive the column 1 to rotate, so that the seedlings on each layer of the cultivation tray 31 face the personnel in turn, realizing a 360-degree all-round dynamic display, which significantly improves the interactivity and ornamental value of agricultural technology promotion.

[0051] Example 3:

[0052] Please see Figure 1 , Figure 9-12 Lugs B511 are welded at intervals on the upper outer wall of the counterweight base 51. The number of lugs B511 is the same as the number of lugs A43, and their positions correspond vertically. A pin or bolt passes through the through hole to achieve a detachable connection between the protective cover 41 and the base assembly 5, preventing the protective cover 41 from being accidentally knocked over or overturned by strong winds. A circular baffle 54 is installed on the outside of the drive motor 52 and battery box 53. The diameter of the circular baffle 54 is larger than the outer contour of the drive motor 52 and battery box 53. The circular baffle 54 is fixed to the upper end of the counterweight base 51 with screws. A ring-shaped array of [unclear - possibly referring to a specific type of counterweight base] is installed at intervals on the upper end of the counterweight base 51. Hollow tube 512 is located around the circular baffle 54. Connecting ropes 411 are installed at intervals on the upper end of the inner cavity of the protective cover 41. The connecting ropes 411 are made of nylon rope, steel wire rope or metal chain. The upper end is fixed to the upper end face of the inner cavity of the protective cover 41 by eye bolts or rivets. Hollow hammer 412 is installed at the lower end of the connecting rope 411. Hollow hammer 412 is a hollow sphere or ellipsoid made of plastic or rubber. Hollow hammer 412 is located between the circular baffle 54 and the hollow tube 512. Actuating plates 6 are symmetrically installed on the lower outer side of the column 1. Actuating plates 6 are located above the circular baffle 54.

[0053] When the column 1 drives the cultivation component 3 to rotate, the column 1 will simultaneously drive the actuating plate 6 to rotate. At this time, the actuating plate 6 will push the hollow hammer 412 to swing and move during the rotation, so that it can touch the hollow tube 512 during the swing to generate slight vibration and sound, forming a continuous physical repulsion signal to drive away insects and birds that try to stay near the protective cover 41 or the cultivation tray 31. This mechanism relies entirely on mechanical movement to produce an insect-repelling effect without the need for any chemical pesticides, which is highly consistent with the concept of green agriculture demonstration.

[0054] Example 4:

[0055] Please see Figure 1 , Figure 9-11The counterweight base 51 is made of metal or high-density concrete in a hemispherical structure. The bottom center of the counterweight base 51 is a solid iron structure, and the overall center of gravity is located below the geometric center, forming a roly-poly-like stability effect. It is not easy to overturn even if it is subjected to external impact. At the same time, when the entire device tilts to the side, the hollow hammer 412 will also tilt. At this time, the hollow hammer 412 on the tilted side will strike the hollow tube 512, and the hollow hammer 412 on the other side will strike the circular baffle 54 to produce vibration and sound, which is used to repel birds and insects. When the entire device tilts to a certain angle, the roller 45 will contact the ground first to provide a fulcrum, which will facilitate the entire device to move back and prevent the entire device from continuing to tilt, thereby increasing the risk of complete collapse.

[0056] Example 5:

[0057] Please see Figure 3 The four sets of cultivation trays 31 can be separated and independently raised and lowered. Then, the four sets of cultivation trays 31 can be raised and lowered to form a spiral staircase around the column 1. When the spiral staircase layout is formed, the height difference between adjacent cultivation trays 31 is set to 100-200mm so that the seedlings in each layer can receive direct light and avoid mutual shading.

[0058] In summary:

[0059] The lower end of the column 1 is coaxially connected to the output shaft of the drive motor 52 in the base assembly 5 via a coupling, and the upper end is threadedly fixed to the threaded sleeve 21 of the top cover 2 via a threaded post 11. The drive motor 52 is powered by a battery in the battery box 53. After starting, it drives the column 1 and the cultivation assembly 3 mounted on it to rotate at a constant speed around the central axis. The counterweight base 51 is a self-righting, low-center-of-gravity stable support; when the device is tilted by external force, the hemispherical curved surface contacts the ground first to provide a fulcrum and prevent complete tipping. The cultivation assembly 3 consists of four sets of 90-degree fan-shaped cultivation trays 31. Each set of cultivation trays 31 is embedded in the guide groove 12 of the column 1 via a guide block 311. After the cultivation trays 31 are adjusted to the target height, bolts are screwed through the connecting holes 313 into the fixing holes 14 to achieve rigid locking. The four sets of cultivation trays 31 can be raised and lowered synchronously to maintain horizontality, or they can be raised and lowered differently to form a spiral stepped layout, so that seedlings in each layer can receive direct light and avoid mutual shading. The lower end of the top cover 2 is equipped with a light source 22 (LED plant growth light) and a power module 23 to simulate the natural light cycle and supplement insufficient light in rainy weather or indoor environments. The planting basket 34 is inserted into the slot 33 from top to bottom, and the baffle 341 is placed on the upper surface of the slot 33 to achieve axial positioning. The basket is filled with seedling substrate, and the drainage hole 342 at the lower end allows excess water to seep into the water collection tray 352 for temporary storage, while preventing substrate loss. The water collection tray 352 is magnetically attached to the fixing iron plate 351 by the magnetic suction piece 353, which not only ensures that it will not fall off during rotation, but also makes it easy to pull and clean by holding the pull rod 354.

[0060] The protective cover 41 is sleeved on the outside of the column 1 via the bearing 42, and the lower end of the support leg 44 is supported by the roller 45 on the ground. It can move synchronously with the device or be fixed independently. The lower end of the column 1 is symmetrically equipped with a lever plate 6. When rotated, it pushes the hollow hammer 412 at the lower end of the connecting rope 411 to swing and move, so that it touches the hollow tube 512 of the ring array, producing slight vibration and sound, forming a physical repulsion mechanism to prevent insects from staying near the protective cover 41 or the cultivation tray 31, thereby reducing the occurrence of pests and diseases.
