Description

Technical Field

[0001] This utility model belongs to the field of Angelica seedling technology, specifically, it relates to an Angelica seedling tray device that facilitates transplanting. Background Technology

[0002] In the Angelica sinensis planting industry, the seedling raising stage is a key prerequisite affecting the survival rate and growth quality of subsequent transplanting. However, the current traditional Angelica sinensis seedling raising equipment and methods have significant shortcomings in terms of transplanting convenience, which has become an important problem restricting the large-scale and efficient planting of Angelica sinensis.

[0003] Traditional angelica seedling cultivation often uses fixed-structure seedbeds or simple plug trays. These devices are not designed with the practical needs of transplanting angelica seedlings in mind. Firstly, the shape of the holes and the inner wall structure of traditional plug trays are not adapted to the growth characteristics of angelica roots. During seedling cultivation, the roots easily adhere tightly to and entangle with the substrate in the plug tray, forming a clump. During transplanting, workers must use tweezers, small shovels, and other tools to forcibly separate the seedlings from the substrate. This is not only cumbersome and time-consuming, but also highly likely to cause root breakage and epidermal damage, impairing the seedling's root absorption function and causing irreversible effects on subsequent seedling recovery and growth.

[0004] On the other hand, the layout design of traditional seedling raising equipment lacks flexibility. Seedling trays are mostly fixed or stacked, making it impossible to adjust their position or easily retrieve them according to the needs of transplanting operations. During transplanting, workers need to frequently bend over and move their bodies to reach seedling trays in different locations, limiting their operating range and increasing labor intensity. Especially in large-scale seedling raising scenarios, the efficiency of retrieving and separating seedlings from a large number of seedling trays is extremely low, making it difficult to meet the needs of rapid transplanting. Furthermore, repeated mechanical operations further increase the probability of seedling damage, resulting in inconsistent seedling survival rates after transplanting and affecting overall planting efficiency.

[0005] In addition, although some seedling raising devices are equipped with a partition structure, the connection between the partition components and the seedling tray is fixed, making it impossible to adjust the limiting space according to the changes in plant shape during the growth of Angelica sinensis seedlings. During transplanting, the partition components are prone to scratching the stems and leaves of the seedlings, and it is also inconvenient for staff to quickly grab the seedlings, further aggravating the inconvenience of transplanting operations. This fails to provide friendly operating conditions for transplanting Angelica sinensis seedlings and restricts the efficiency and quality improvement of the Angelica sinensis seedling transplanting process.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] Example 1: To address the problem that existing Angelica seedling cultivation devices are inconvenient for transplanting Angelica seedlings, such as... Figures 1 to 8 As shown, an angelica seedling tray device for easy transplanting includes a seedling box 1 and a base plate 2 fixedly installed at the bottom of the seedling box 1. A glass cover plate 3 is slidably connected to the top of the seedling box 1. A control box 5 is fixedly installed on the right side of the seedling box 1. A fan 4 is installed on the outer surface of the seedling box 1. A seedling mechanism is provided on the top of the base plate 2. The seedling raising mechanism includes a turntable 6, a rotating shaft 601, a seedling tray 602, a pull rod 603, and a nutrient solution tank 604. The rotating shaft 601 is fixedly connected to the top center of the base plate 2, the turntable 6 is rotatably connected to the top of the rotating shaft 601, the seedling tray 602 is set on the top outer surface of the turntable 6, the pull rod 603 is fixedly connected to the top of the seedling tray 602, and the nutrient solution tank 604 is set at the top center of the turntable 6. Seedling trays 602 are evenly distributed on the top of the turntable 6, and adjacent seedling trays 602 are separated by a partition plate 7. The outer surface of the partition plate 7 has a sliding groove, and a connecting slider 609 is slidably connected inside the sliding groove. A retaining ring 608 is fixedly connected to the surface of the connecting slider 609. The upper surface of the partition plate 7 has an installation groove 701, and an electric heating wire is installed inside the installation groove 701. A connecting seat 702 is installed on the top of the partition plate 7 by a locking bolt 703. A magnetic strip 704 is fixedly connected to the outer surface of the connecting seat 702. The retaining ring 608 is made of iron. The upper surface of the partition plate 7 has a bolt hole, and the locking bolt 703 passes through the connecting seat 702 and is threaded into the inner wall of the bolt hole.

[0021] The center of the partition plate 7 is connected to the nutrient solution tank 604. A shelf 6043 is fixedly connected to the middle of the inner wall of the nutrient solution tank 604. A connecting pipe 611 is fixedly connected to the bottom of the shelf 6043. A water distribution pipe 610 is fixedly connected to the bottom of the connecting pipe 611. A through hole 6041 is opened at the bottom of the inner wall of the nutrient solution tank 604. The water distribution pipe 610 passes through the through hole 6041 and extends into the inside of the seedling tray 602. A permeation hole 6042 is opened on the upper surface of the shelf 6043. A dust cover 605 is fixedly installed on the top of the nutrient solution tank 604.

[0022] The 6042 permeable pores adopt an inverted conical structure that is narrower at the top and wider at the bottom. The diameter of the upper port is 2-3 mm, and the diameter of the lower port is enlarged to 3-4 mm. This structure can reduce the flow resistance of the nutrient solution in the pores and reduce the probability of impurities adhering to the inner wall of the pores. Even if a small amount of fine impurities enter the pores, they will flow downwards quickly with the nutrient solution under the action of gravity and are not likely to accumulate and block the pores.

[0023] Example 2: Based on Example 1, a motor 606 is installed at the top center of the dust cover 605. The output end of the motor 606 passes through the dust cover 605 and extends into the nutrient solution tank 604, where a stirring shaft 6044 is connected. A stirring blade 6045 is fixedly connected to the outer surface of the stirring shaft 6044. A stirring plate 6046 is fixedly connected to the side of the stirring blade 6045 away from the stirring shaft 6044. A sliding groove is formed on the surface of the stirring plate 6046. A slider 6047 is slidably connected inside the sliding groove. A telescopic spring 6048 is fixedly connected to the side of the slider 6047 away from the stirring shaft 6044. A scraper 6049 is fixedly connected to the end of the telescopic spring 6048 away from the slider 6047. A connecting plate 60410 is fixedly connected to the end of the stirring plate 6046 away from the stirring blade 6045. A vibrating plate 60411 is fixedly connected to the end of the connecting plate 60410 away from the stirring plate 6046.

[0024] Assembly before use in seedling cultivation: First, place the base plate 2 horizontally and fix the seedling box 1 on top of the base plate 2, ensuring that the seedling box 1 and the base plate 2 are tightly connected and without shaking. Next, slide the glass cover 3 onto the top of the seedling box 1 and test whether the sliding is smooth, ensuring that it can be opened and closed flexibly for easy observation of the seedling growth and operation. Then, fix the control box 5 on the right side of the seedling box 1, install the fan 4 at a suitable position on the outer surface of the seedling box 1, and connect the wiring of the control box 5 and the fan 4 respectively, ensuring that the fan 4 can be normally controlled to start and stop through the control box 5.

[0025] A rotating shaft 601 is fixedly connected to the center of the top of the base plate 2. The turntable 6 is then rotated and connected to the top of the rotating shaft 601. The turntable 6 is checked to ensure that it rotates smoothly without any jamming. Next, seedling trays 602 are evenly spaced on the outer surface of the top of the turntable 6, with a partition plate 7 separating adjacent seedling trays 602. The partition plate 7 must be securely fixed to the turntable 6. A connecting slider 609 is slidably installed in a groove on the outer surface of the partition plate 7, and an iron retaining ring 608 is fixedly connected to the surface of the connecting slider 609.

[0026] An installation groove 701 is made on the upper surface of the partition plate 7. The heating wire is installed inside the installation groove 701. The wiring of the heating wire is properly connected to ensure that it can be controlled by the control box 5. The connecting seat 702 is installed on the top of the partition plate 7 by locking bolts 703. The locking bolts 703 must pass through the connecting seat 702 and be threaded into the inner wall of the bolt hole made on the upper surface of the partition plate 7 to ensure that the connecting seat 702 is installed firmly. Finally, a magnetic strip 704 is fixedly connected to the outer surface of the connecting seat 702.

[0027] A nutrient solution tank 604 is positioned at the center of the top of the turntable 6, connecting the center of the partition plate 7 to the nutrient solution tank 604. A shelf 6043 is fixedly connected to the middle of the inner wall of the nutrient solution tank 604. A connecting pipe 611 is fixedly connected to the bottom of the shelf 6043, and a water distribution pipe 610 is fixedly connected to the bottom of the connecting pipe 611. The water distribution pipe 610 must penetrate through the through hole 6041 at the bottom of the inner wall of the nutrient solution tank 604 and extend into the seedling tray 602. A permeation hole 6042 is also provided on the upper surface of the shelf 6043. A dust cover 605 is fixedly installed on the top of the nutrient solution tank 604. A motor 606 is installed at the center of the top of the dust cover 605. The output end of the motor 606 penetrates through the dust cover 605 and extends into the nutrient solution tank 604, connecting to the stirring shaft 6044. A stirring blade 6045 is fixedly connected to the outer surface of the stirring shaft 6044, and a stirring plate 6046 is fixedly connected to the side of the stirring blade 6045 away from the stirring shaft 6044. A slider 6047 is slidably installed in a sliding groove on the surface of the stirring plate 6046. A telescopic spring 6048 is fixedly connected to the side of the slider 6047 away from the stirring shaft 6044, and a scraper 6049 is fixedly connected to the end of the telescopic spring 6048 away from the slider 6047. A connecting plate 60410 is fixedly connected to the end of the stirring plate 6046 away from the stirring blade 6045, and a vibrating plate 60411 is fixedly connected to the end of the connecting plate 60410 away from the stirring plate 6046.

[0028] Open the glass cover 3, adjust the seedling tray 602 to a suitable position using the pull rod 603, fill the seedling tray 602 with a suitable substrate for angelica seedling cultivation, sow the angelica seeds evenly in the substrate, and then slide the connecting slider 609 as needed to adjust the position of the iron retaining ring 608. Use the magnetic strip 704 to adsorb and fix the retaining ring 608 to properly separate the seeds.

[0029] By turning on fan 4 through control box 5, the air circulation inside seedling box 1 is regulated to ensure fresh air inside the box. According to the temperature required for angelica seedling cultivation, the heating wire inside partition plate 7 is controlled through control box 5 to maintain the temperature inside seedling box 1 within a suitable range for angelica growth.

[0030] Open the dust cover 605 on top of the nutrient solution tank 604, and add the prepared Angelica seedling nutrient solution into the nutrient solution tank 604. The nutrient solution will seep downwards through the permeation holes 6042 on the shelf 6043, enter the water distribution pipe 610 through the connecting pipe 611, and then be transported to each seedling tray 602 by the water distribution pipe 610 to provide nutrients for the growth of Angelica seedlings. At the same time, the motor 606 can be started through the control box 5. The motor 606 drives the stirring shaft 6044 to rotate, and the stirring shaft 6044 drives the stirring blades 6045 and the stirring plate 6046 to rotate, stirring the nutrient solution and making the nutrient solution composition uniform. During the stirring process, the scraper 6049 is pressed against the inner wall of the nutrient solution tank 604 under the action of the telescopic spring 6048, which can clean the nutrient solution adhering to the tank wall. The vibrating plate 60411 vibrates with the rotation of the stirring plate 6046, which can prevent the nutrient solution from clogging during the transportation process.

[0031] When the angelica seedlings have grown to the stage suitable for transplanting, open the glass cover 3, slide the connecting slider 609, remove the retaining ring 608, and take the seedling tray 602 off the turntable 6 by pulling the rod 603, and then the angelica seedlings can be transplanted.

[0032] Seedling tray 602 is made of food-grade PP polypropylene material, with a thickness of 2-3mm. It is resistant to aging, high temperatures from -20℃ to 80℃, and impact, with a service life of 3-5 years. Compared to traditional plastic seedling trays, its air permeability is increased by 30%, which can effectively reduce the problem of root hypoxia and rot.

[0033] Each hole in the bottom of the 602 seedling tray has 1-2 drainage holes with a diameter of 0.5-1cm. Cover the drainage holes with a 200-mesh nylon filter to prevent substrate loss and ensure that excess water is drained quickly, avoiding waterlogging and root rot.

[0034] The width of the groove on the outer surface of the separator 7 is 1.5-2cm, and the gap between the connecting slider 609 and the groove is 0.1-0.2cm, ensuring smooth sliding of the slider without significant wobbling. The retaining ring 608 can be adjusted in position within a range of 0-10cm along the groove, with an adjustment accuracy of up to 0.5cm, which can precisely adjust the limiting space according to the size of the Angelica seeds and the sowing density.

[0035] The magnetic strip 704 is made of neodymium iron boron strong magnetic material with a surface magnetic field strength of 800-1000 Gauss. After being attracted to the iron retaining ring 608, the fixing pull can reach 5-8N, which can effectively resist the root thrust and slight collision during the seedling growth process, ensure the stability of the retaining ring position and avoid seedling displacement.

[0036] Motor 606 uses a DC geared motor with a power of 100-150W and adjustable speed. The stirring blades 6045 are spiral-shaped, with 3-4 blades, a blade width of 5-6cm, and a length of 8-10cm. During stirring, they can create upward and downward convection, improving the uniformity of nutrient solution mixing to over 95% and completely solving the problem of component precipitation.

[0037] The scraper 6049 is made of silicone with a thickness of 1-1.5cm. Its contact pressure with the inner wall of the nutrient solution tank 604 is 2-3N, adjustable via a telescopic spring 6048. As the scraper rotates with the stirring plate 6046, it controls the residual nutrient solution adhering to the tank wall to within 0.5g / ㎡, reducing nutrient waste and preventing contamination of the new solution by residual nutrient solution.

[0038] The water distribution pipe 610 is made of PVC and has a diameter of 1.5-2cm. Each water distribution pipe 610 has 8-12 water outlet holes with a diameter of 0.3-0.5cm, which are distributed at a 45° downward angle. The water distribution pipe 610 corresponds one-to-one with the holes of the seedling tray 602. The flow rate of the nutrient solution is controlled at 5-10ml / min to ensure that each seedling receives an equal amount of nutrients, and the uniformity of seedling growth is improved to over 90%.

[0039] The heating wires are made of nickel-chromium alloy with a power of 200-300W. Each partition plate 7 contains 2-3 heating wires arranged in an S-shape. The control box 5 has a built-in temperature sensor and PID controller, which can accurately control the temperature inside the seedling box 1 at 18-25℃, with a temperature fluctuation range not exceeding ±1℃.

[0040] Fan 4 uses an axial flow fan with an airflow of 100-150 m³ / h. 3 The number of fans is 2-4 per hour, symmetrically installed on both sides of the seedling box 1. The control box 5 is also connected to a humidity sensor. When the humidity inside the box exceeds 85%RH, the fan 4 will automatically turn on to ventilate and reduce humidity; when the humidity is below 60%RH, it can be used with an external spray device to increase humidity, ensuring that the humidity is maintained within the suitable range of 65%-80%RH.

[0041] Working principle: This easy-to-transplant Angelica seedling tray device uses the seedling box 1 as the whole seedling space and the base plate 2 as the supporting foundation. The seedling mechanism realizes the cultivation of Angelica seedlings. At the same time, the control box 5 controls the fan 4, heating wire, motor 606 and other components to provide suitable environmental conditions and nutrient supply for Angelica seedling cultivation, ultimately achieving the purpose of facilitating the cultivation and transplanting of Angelica seedlings.

[0042] The rotating shaft 601 is fixed at the top center of the base plate 2, and the turntable 6 can rotate flexibly around the rotating shaft 601, which makes it convenient for staff to operate the seedling trays 602 at different positions during the seedling raising process, such as sowing, observing the growth of seedlings, adding substrate, etc., thus improving the convenience of seedling raising operations.

[0043] The seedling tray 602 is used to hold the Angelica seedling substrate and seeds, providing space for the growth of Angelica seedlings. The pull rod 603 is fixed to the top of the seedling tray 602, making it easy for staff to move and pick up the seedling tray 602. During transplanting, the seedling tray 602 can be easily removed from the turntable 6 by using the pull rod 603, reducing the difficulty of the transplanting operation.

[0044] The separator 7 separates adjacent seedling trays 602, preventing interference between the substrate and seedlings in different trays and ensuring a relatively independent growth environment for each tray. The retaining ring 608 is slidably connected to the separator 7 via a connecting slider 609. Its position can be adjusted according to the sowing density of the angelica seeds and the growth of the seedlings, providing a certain degree of restraint for the seeds and seedlings and preventing them from shifting during growth. Simultaneously, the retaining ring 608, being made of iron, can be attracted and fixed to the magnetic strip 704 on the separator 7, ensuring its stable position during seedling cultivation. The retaining ring 609 also provides restraint, guiding the orderly growth of the roots and reducing root entanglement. When removing the seedlings, the roots are less likely to break or be damaged, providing a good foundation for subsequent transplanting and ensuring the survival rate of the seedlings after transplanting.

[0045] Fan 4 is installed on the outer surface of seedling box 1 and is controlled to start and stop via control box 5. When fan 4 is working, it promotes air circulation inside and outside seedling box 1, expelling stale air and drawing in fresh air to ensure fresh air inside the box, providing sufficient oxygen for the growth of angelica seedlings. It also helps to regulate the temperature and humidity inside the box, avoiding a high-temperature and high-humidity environment and reducing the occurrence of pests and diseases.

[0046] The heating wire is installed in the mounting groove 701 of the partition plate 7, and the heating is controlled by the control box 5. When the temperature inside the seedling box 1 is lower than the suitable temperature required for the growth of Angelica dahurica seedlings, the heating wire is energized and heats up. The heat is transferred to the seedling box 1 through the partition plate 7, raising the temperature inside the box and maintaining it within a suitable range, providing a warm environment for the growth of Angelica dahurica seedlings and promoting their growth and development.

[0047] The nutrient solution tank 604 is used to store the nutrient solution required for Angelica sinensis seedling cultivation. A shelf 6043 divides the nutrient solution tank 604 into upper and lower parts: the upper part is the nutrient solution storage area, and the lower part is the nutrient solution delivery area. The nutrient solution slowly permeates through the permeation holes 6042 on the shelf 6043 to the lower part, enters the connecting pipe 611, and is then delivered to each seedling tray 602 through the water distribution pipe 610, providing a continuous and stable nutrient supply for the growth of Angelica sinensis seedlings. The water distribution pipe 610 extends into the inside of the seedling tray 602, allowing the nutrient solution to be directly delivered to the substrate, improving the utilization rate of the nutrient solution.

[0048] After the motor 606 starts, it drives the stirring shaft 6044, stirring blades 6045, and stirring plate 6046 to rotate, stirring the nutrient solution in the nutrient solution tank 604. This ensures that the various nutrients in the nutrient solution are evenly mixed, preventing nutrient precipitation and ensuring that each angelica seedling absorbs balanced nutrients. During the stirring process, the scraper 6049 remains in close contact with the inner wall of the nutrient solution tank 604 under the elastic force of the telescopic spring 6048. As the stirring plate 6046 rotates, the scraper 6049 scrapes and cleans the nutrient solution adhering to the tank wall, preventing the nutrient solution from solidifying and being wasted, and also preventing dirt on the tank wall from affecting the quality of the nutrient solution. The vibrating plate 60411 rotates together with the stirring plate 6046, generating vibration during rotation. This vibration is transmitted to the connecting pipe 611 and the water distribution pipe 610, preventing impurities in the nutrient solution from accumulating and clogging the pipes, ensuring the smooth flow of nutrient solution.

[0049] This device is not only suitable for Angelica sinensis seedling cultivation, but also for the cultivation of seedlings of Chinese medicinal herbs such as Codonopsis pilosula, Astragalus membranaceus, and Glycyrrhiza uralensis, as well as vegetable seedlings such as tomatoes, peppers, and eggplants, by changing the seedling trays 602 of different specifications, thereby reducing equipment investment costs.

[0050] By increasing the number of turntables (6) and adopting a multi-layered, three-dimensional structure, space utilization can be improved. Meanwhile, the control box (5) supports IoT module expansion, allowing remote monitoring of seedling environment parameters via a mobile app and enabling automatic adjustment. A single worker can manage 5-10 sets of equipment, significantly improving the efficiency of large-scale seedling cultivation.

[0051] The seedling box 1 uses a double-layer hollow glass cover 3, which improves the heat preservation performance by 40%. When temporarily raising seedlings outdoors, it can withstand the external temperature fluctuations from -10℃ to 35℃, ensuring the normal growth of seedlings. It is suitable for temporary seedling raising needs in the field.
