Description

Technical Field

[0001] This invention relates to the field of seedling raising equipment technology, specifically to a seedling raising device for agricultural planting and its seedling raising method. Background Technology

[0002] In agricultural planting, seedling raising is a crucial step in the crop growth cycle, directly affecting the crop's growth rate, yield, and quality. Traditional seedling raising methods often involve open-field or simple facility-based methods, which have many drawbacks, such as difficulties in water management, susceptibility to pests and diseases, and large fluctuations in environmental temperature, leading to unstable seedling results and difficulty in guaranteeing seedling survival rate and quality.

[0003] To address the shortcomings of traditional seedling cultivation methods, people began exploring the use of seedling cultivation devices. While early seedling cultivation devices improved seedling efficiency to some extent, they still had several problems. For example, some devices had inadequate water management systems, failing to precisely control water supply and leading to overly wet or dry soil, which negatively impacted seedling growth. Other devices had poor structural designs, making installation and disassembly difficult and hindering seedling transplantation and management. Still others had poor sealing, making them susceptible to external environmental influences, such as pests and diseases, and temperature fluctuations. Summary of the Invention

[0004] The purpose of this invention is to provide a seedling raising device and method for agricultural planting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a seedling raising device for agricultural planting, comprising a mounting frame, a seedling outer shell screwed to the top of the mounting frame, a seedling inner shell fixed inside the seedling outer shell, an absorbent cotton cover fixed inside the seedling inner shell, an absorbent cotton core fixed at the bottom end of the absorbent cotton cover, the absorbent cotton core penetrating the bottom plate of the seedling inner shell, a water pipe installed at the bottom end of the mounting frame, a one-way water valve inserted and fixed at the top end of the water pipe, the one-way water valve penetrating the bottom plate of the seedling outer shell.

[0006] Preferably, the top surface of the mounting frame has a mounting opening, which is circular. There are multiple mounting openings, which are arranged at equal intervals and of equal size along the long side of the mounting frame. A threaded sleeve is fixed inside the mounting opening. The inner ring surface of the threaded sleeve has an internal thread. The outer wall of the seedling shell has an external thread at the top. The external thread and the internal thread are connected. An overlapping ring is fixed on the outer wall of the seedling shell and overlaps the threaded sleeve.

[0007] Preferably, the seedling inner shell has an inverted frustum frame structure, a metal mesh cover is provided above the absorbent cotton cover, the metal mesh cover is fixed inside the seedling inner shell, and multiple perforations are opened on the bottom surface of the seedling inner shell. The absorbent cotton core corresponds to each perforation, and the bottom end of the absorbent cotton core passes through the perforation and is fixed to the bottom plate of the seedling outer shell.

[0008] Preferably, the bottom end of the mounting frame is integrally formed with a tube bundle frame, which is an arc-shaped plate. The water pipe is pushed into the tube bundle frame, and multiple sets of hoop plates are hinged to the bottom of the tube bundle frame. Each set of hoop plates has two plates, and the two hoop plates are connected by bolts.

[0009] Preferably, the top surface of the tube bundle frame has a second perforation. The one-way water valve passes through the second perforation and is inserted into the socket. The socket is located on the bottom surface of the seedling shell. A baffle plate is inserted into the top of the socket. The baffle plate is an inverted frustum plate. A rubber band is fixed to the top surface of the baffle plate. Both ends of the rubber band are fixed to the bottom plate of the seedling shell, and the two ends of the rubber band are distributed on both sides of the socket. Two top rods are fixed to the top of the one-way water valve.

[0010] A method for raising seedlings using an agricultural seedling raising device, the method comprising the following steps:

[0011] The water pipe is pushed into the tube bundle frame beforehand, and the water pipe is fixed in the tube bundle frame by clamps and bolts;

[0012] Place the seedling inner shell containing the seedlings into the installation port, and screw the seedling outer shell into the groove of the installation port.

[0013] As the seedling outer shell is pushed down, the one-way water valve is inserted into the socket, and the baffle is pushed up by the top rod. When the two ends of the water pipe are connected to the water supply pipe, the water pipe injects clean water into the area between the seedling outer shell and the seedling inner shell through the one-way water valve. The water-absorbing cotton core and water-absorbing cotton cover absorb the clean water and irrigate the soil inside the seedling inner shell, providing water for seedling growth.

[0014] After the seedlings are cultivated, the outer seedling shell is removed from the installation port. The outer seedling shell, together with the inner seedling shell, is used as a transport structure for the seedlings.

[0015] Preferably, when installing the water pipe, the one-way water valve is aligned with the second perforation on the surface of the tube bundle frame, and the water pipe is pushed into the tube bundle frame. Then, the water pipe is fixed to the bottom of the tube bundle frame by two clamps and bolts.

[0016] Preferably, when installing the seedling shell, the bottom of the seedling shell is pushed into the installation port, and the seedling shell and the threaded sleeve are screwed together until the overlapping ring overlaps the top surface of the threaded sleeve. At this time, the one-way water valve is inserted into the socket, and the push rod pushes the baffle from the top of the socket, and the rubber band is stretched by the baffle to produce elastic deformation.

[0017] Preferably, when watering the seedlings, the end of the installation port is connected to the water supply pipe. After the water supply pipe is filled with water, clean water is injected into the area between the corresponding seedling outer shell and seedling inner shell through the water pipe and the one-way water valve. The water-absorbing cotton cover and water-absorbing cotton core absorb the clean water and saturate the soil inside the seedling inner shell, thereby realizing the watering of the seedling roots.

[0018] Preferably, after the seedling cultivation is completed, the seedling outer shell is twisted to detach from the silk sleeve. When the top of the seedling outer shell is above the one-way water valve, the rubber band rebounds and pulls the baffle plate into the top of the socket to seal the socket.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention proposes an agricultural seedling raising device and method. By installing a water-absorbing cotton cover and a water-absorbing cotton core inside the seedling inner shell, the water-absorbing properties of the materials allow for precise control of soil moisture supply. When water is supplied through the water pipe, clean water is injected into the area between the outer and inner shells of the seedling. The water-absorbing cotton cover and core absorb the water and saturate the soil inside the inner shell, achieving precise irrigation of the seedling roots. The one-way water valve penetrates the bottom plate of the outer shell and is inserted into the socket. A sealing ring fixed to the surface of the socket clamps between the socket and the one-way water valve, effectively preventing water leakage. When the outer shell detaches from the silk sleeve, a rubber band rebounds and pulls a baffle plate into the top of the socket, automatically sealing the socket and further improving the device's sealing performance.

The top surface of the mounting frame 1 has a mounting opening 3. The mounting opening 3 is circular and has multiple mounting openings 3. The multiple mounting openings 3 are arranged at equal intervals and of equal size along the long side of the mounting frame 1. A threaded sleeve 4 is fixed inside the mounting opening 3. The inner ring surface of the threaded sleeve 4 has an internal thread. The outer wall of the seedling outer shell 5 has an external thread at the top. The external thread and the internal thread are connected. An overlapping ring 7 is fitted and fixed on the outer wall of the seedling outer shell 5 and overlaps the threaded sleeve 4.

[0031] An absorbent cotton cover 9 is fixed inside the seedling inner shell 6. An absorbent cotton core 11 is fixed at the bottom of the absorbent cotton cover 9. The absorbent cotton core 11 penetrates the bottom plate of the seedling inner shell 6. The seedling inner shell 6 has an inverted frustum frame structure. A metal mesh cover 8 is provided above the absorbent cotton cover 9. The metal mesh cover 8 is fixed inside the seedling inner shell 6. Multiple perforations 10 are opened on the bottom surface of the seedling inner shell 6. The absorbent cotton core 11 and the perforations 10 correspond one-to-one. The bottom end of the absorbent cotton core 11 passes through the perforations 10 and is fixed to the bottom plate of the seedling outer shell 5. When watering the seedlings, the end of the installation port 3 is connected to the water supply pipe. After the water supply pipe is filled with water, clean water is injected into the area between the corresponding seedling outer shell 5 and the seedling inner shell 6 through the water pipe 12 and the one-way water valve 16. The absorbent cotton cover 9 and the absorbent cotton core 11 absorb the clean water and saturate the soil inside the seedling inner shell 6, thereby irrigating the roots of the seedlings.

[0032] A water pipe 12 is installed at the bottom of the mounting frame 1, and a one-way water valve 16 is inserted and fixed at the top of the water pipe 12. The one-way water valve 16 penetrates the bottom plate of the seedling shell 5. A bundled tube frame 2 is integrally formed at the bottom of the mounting frame 1. The bundled tube frame 2 is an arc-shaped plate. The water pipe 12 is pushed into the bundled tube frame 2. Multiple sets of hoop plates 13 are hinged at the bottom of the bundled tube frame 2. Each set of hoop plates 13 has two, and the two hoop plates 13 are connected by bolts 14. A through hole is opened on the top surface of the bundled tube frame 2. The one-way water valve 16 passes through the perforation 15 and is inserted into the socket 17. The socket 17 is located on the bottom surface of the seedling shell 5. A baffle 19 is inserted into the top of the socket 17. The baffle 19 is an inverted frustum plate. A rubber band 20 is fixed to the top surface of the baffle 19. Both ends of the rubber band 20 are fixed to the bottom plate of the seedling shell 5, and the two ends of the rubber band 20 are distributed on both sides of the socket 17. Two push rods 18 are fixed to the top of the one-way water valve 16. When installing the water pipe 12, align the one-way water valve 16 with the perforation 15 on the surface of the tube bundle frame 2, and push the water pipe 12 into the tube bundle frame 2. Then, fix the water pipe 12 to the bottom of the tube bundle frame 2 with two clamps 13 and bolts 14. When installing the seedling shell 5, push the bottom of the seedling shell 5 into the installation port 3, and screw the seedling shell 5 and the threaded sleeve 4 until the overlapping ring 7 overlaps the top surface of the threaded sleeve 4. At this time, the one-way water valve 16 is inserted into the socket 17. The surface of the socket 17 is fixed with a sealing ring 21. The sealing ring 21 is clamped between the socket 17 and the one-way water valve 16. The push rod 18 pushes the baffle 19 from the top of the socket 17, and the rubber band 20 is stretched by the baffle 19 to produce elastic deformation. After the seedling cultivation is completed, the seedling outer shell 5 is twisted off from the thread sleeve 4. When the top of the seedling outer shell 5 is above the one-way water valve 16, the rubber band 20 rebounds and pulls the baffle 19 into the top of the socket 17 to seal the socket 17.

[0033] Example 2, based on Example 1, proposes a seedling cultivation method, including the following steps:

[0034] Mounting Frame Preparation: Place mounting frame 1 in a suitable position, ensuring it is stable. Insert the one-way water valve 16 into the top of water pipe 12. Push water pipe 12 into the tube bundle frame 2 at the bottom of mounting frame 1. Use two clamps 13 and bolts 14 to secure water pipe 12 to the bottom of tube bundle frame 2, ensuring it does not wobble. Ensure the top of the one-way water valve 16 is aligned with the second perforation 15 on the surface of tube bundle frame 2 for subsequent connection to the seedling outer shell 5.

[0035] Installation of the seedling outer shell and inner shell: Align the bottom of the seedling outer shell 5 with the mounting opening 3 on the top surface of the mounting bracket 1, and screw the seedling outer shell 5 so that the external thread of its outer wall engages with the internal thread of the threaded sleeve 4 inside the mounting opening 3. Tighten until the overlapping ring 7 overlaps the top surface of the threaded sleeve 4, ensuring that the seedling outer shell 5 is securely fixed. During this process, the one-way water valve 16 should be smoothly inserted into the insertion opening 17 on the bottom surface of the seedling outer shell 5. Ensure that the sealing ring 21 on the surface of the insertion opening 17 is clamped between the insertion opening 17 and the one-way water valve 16, thus providing a seal. The push rod 18 at the top of the one-way water valve 16 pushes the baffle 19 up from the top of the insertion opening 17, and the rubber band 20 is stretched by the baffle 19, causing elastic deformation.

[0036] Soil and seedling placement: Place an appropriate amount of soil inside the seedling inner shell 6. Plant the seedlings in the soil, ensuring that the roots of the seedlings can contact the absorbent cotton cover 9 and the absorbent cotton core 11.

[0037] Irrigation system connection: Connect the end of the installation port 3 to the water supply pipe (this step may be performed before or after installing the seedling outer shell 5, depending on the convenience of actual operation). Water is supplied through the water supply pipe, and clean water is injected into the area between the corresponding seedling outer shell 5 and seedling inner shell 6 through the water pipe 12 and the one-way water valve 16. The absorbent cotton cover 9 and absorbent cotton core 11 absorb the clean water and saturate the soil inside the seedling inner shell 6, thereby irrigating the roots of the seedlings.

[0038] After seedling cultivation is completed, the outer seedling shell 5 is twisted to detach it from the silk sleeve 4. When the top of the outer seedling shell 5 is above the one-way water valve 16, the rubber band 20 rebounds and pulls the baffle 19 into the top of the socket 17, thus sealing the socket 17. The cultivated seedlings are then removed from the inner seedling shell 6 for subsequent planting or treatment.
