Description

Technical Field

[0001] This utility model relates to the field of mulberry seedling technology, specifically a mulberry cutting propagation device. Background Technology

[0002] Mulberry trees are an important economic crop, widely used in sericulture and ecological forestry. With the development of agricultural modernization, higher demands are placed on the efficiency and survival rate of mulberry seedling cultivation. Traditional mulberry propagation methods mainly rely on seed propagation and artificial cuttings. However, seed propagation suffers from problems such as large genetic variations and long growth cycles, while artificial cuttings are labor-intensive, inefficient, and difficult to ensure uniformity in cutting depth and spacing, affecting the uniformity of seedlings and subsequent management.

[0003] The patent currently published with the number CN219514718U discloses a mulberry cutting propagation device, which includes a water storage tank and an adjustment frame that is slidably set in the water storage tank. The water storage tank is provided with a support component for controlling the reciprocating movement of the adjustment frame. The adjustment frame is provided with a number of seedling trays, and seedling kits can be inserted into each seedling tray. The seedling kits include symmetrically arranged arc sleeves that can form a cylinder. The outer wall of each arc sleeve is fixed with a limiting block that has the same shape and size as the inner side of the seedling tray. The lower end of the seedling kit is provided with an absorbent sponge, and each arc sleeve is provided with a number of ventilation slots.

[0004] However, the aforementioned device has the following problems in use: The mulberry seedling cultivation device is designed with a planar structure. When handling cuttings and inserting them, operators need to frequently move around the seedbed to complete the tasks, resulting in high labor intensity and low efficiency. This is especially true in the central area of ​​the seedbed, where the operator must lean out to operate, and obstructed views further complicate manual operation. Furthermore, the seedbed lacks effective heat preservation and environmental control devices, making it only suitable for use in greenhouses and difficult to promote in early spring, winter, or other harsh weather conditions. This limits its adaptability to different seasons and geographical regions, failing to meet the needs of diverse seedling cultivation scenarios, and consequently affecting the germination rate and overall seedling quality. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a mulberry cutting propagation device that not only reduces labor intensity but can also adapt to various indoor and outdoor usage scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 6A mulberry cutting propagation device includes a support frame 1, on which two rotating disks 2 are rotatably mounted. A connecting rod 15 is fixedly installed between the two rotating disks 2. Mounting blocks 3 are fixedly installed at equal intervals on the surfaces of the two rotating disks 2 facing each other. Gravity blocks 4 are fitted on the mounting blocks 3. A seedling frame 5 is fixedly installed between the corresponding gravity blocks 4.

[0026] This structure allows multiple seedling frames 5 to be distributed circumferentially around the rotating disk 2. The gravity block 4 moves outward under the action of centrifugal force along with the mounting block 3. The rotation trajectory of the seedling frame 5 is stabilized by the gravity balancing effect, avoiding vibration or deviation, and realizing the periodic uniform rotation of the seedling frame 5, ensuring that the cutting mulberry seedlings receive light evenly and the nutrient solution is distributed uniformly.

[0027] In practical use, operators can stand in a fixed position and rotate the rotating disk 2 to perform activities such as soil preparation and planting in different positions of the seedling frames 5. This method is convenient to operate while occupying a small area.

[0028] The support frame 1 is equipped with a drive mechanism for rotation.

[0029] A pleated cover 6 is fixedly installed on the support frame 1, and a movable frame 7 is fixedly installed on the other end of the pleated cover 6. A retractable device is provided on the support frame 1.

[0030] The accordion cover 6 has a folding structure, which unfolds or closes as the moving frame 7 moves.

[0031] When used outdoors, in the event of strong sunlight, rain, snow or severe weather, the movable frame 7 is moved by the retraction device, and the accordion cover 6 is moved simultaneously, so that the accordion cover 6 can be unfolded to form a top shading area to prevent strong sunlight from scorching the tender shoots or rain from affecting the substrate.

[0032] A ventilation fan 9 is installed on the support frame 1.

[0033] When used inside the greenhouse, the accordion cover 6 can be unfolded. Through the cooperation of the accordion cover 6 and the support frame 1, the space where the mulberry seedlings are placed can form a closed space that can keep warm, so there is no need to keep the entire greenhouse warm, which can effectively save energy. By turning on the ventilation fan 9, ventilation can be achieved.

[0034] The drive mechanism includes a stepper motor 10, which is mounted on a support frame 1. A drive shaft 14 is fixedly mounted on the output end of the shaft of the stepper motor 10. The drive shaft 14 passes through the support frame 1 and is fixedly connected to the center of one of the rotating disks 2.

[0035] The stepper motor 10 precisely controls the rotation angle and speed of the rotating disk 2, so that the seedling frame 5 rotates intermittently according to the set program, which facilitates manual or mechanical fixed-point cutting, watering, and testing, avoids frequent movement, and improves work efficiency.

[0036] The retraction device includes a fixed plate 8 and a servo motor 13. The fixed plate 8 is fixedly installed on the support frame 1. Threaded rods 16 are rotatably installed inside both the fixed plate 8 and the support frame 1. A synchronous chain 17 is installed between the two threaded rods 16 through a sprocket. Nut pairs 18 are threadedly installed on both threaded rods 16. Connecting blocks 19 are fixedly installed on both nut pairs 18. The connecting blocks 19 are fixedly connected to the moving frame 7.

[0037] Preferably, the sprocket and the synchronous chain 17 can be driven by a tooth or a chain to ensure the transmission ratio and avoid slippage.

[0038] The servo motor 13 is mounted on the support frame 1, and the output end of the shaft of the servo motor 13 is connected to the center of one of the threaded rods 16.

[0039] After the servo motor 13 starts, it drives the threaded rod 16 to rotate. The twin screws are linked by the synchronous chain 17. The nut pair 18 drives the connecting block 19 to move, thereby pushing the moving frame 7 to slide back and forth, realizing the opening and closing of the bellows cover 6. This design can automatically adjust the shading range according to climatic conditions (such as strong winds and low temperatures) to achieve flexible heat preservation or ventilation.

[0040] The cross-sections of the accordion cover 6 and the movable frame 7 are rectangular, and the two connecting blocks 19 are located on the upper and lower sides of the movable frame 7, respectively.

[0041] The rectangular structure ensures the sealing effect of the accordion cover 6, and the symmetrically arranged connecting blocks 19 ensure the smooth movement of the moving frame 7, making it suitable for frequent opening and closing scenarios and enhancing the stability and reliability of the device operation.

[0042] A protective chamber 12 is fixedly installed on the support frame 1, and the synchronous chain 17 is located inside the protective chamber 12. The protective chamber 12 effectively isolates the synchronous chain 17 from external dust, moisture and other adverse factors, extends the service life of the transmission system, reduces the maintenance frequency, and ensures the long-term stable operation of the equipment.

[0043] A sealing gasket 20 is inlaid on the side of the movable frame 7 away from the shielding accordion cover 6. The sealing gasket 20 plays a good sealing role when the movable frame 7 is closed, preventing cold air, rain or dust from entering and maintaining a constant temperature in the seedling area. It is especially suitable for seedling operations in early spring or winter low temperature environments.

[0044] The support frame 1 has a fixed frame 11 fixedly installed at the air outlet of the ventilation fan 9. A filter plate 21 is inlaid on the fixed frame 11. The filter plate 21 can effectively filter impurities in the air entering the seedling area when it is closed, and is especially suitable for use in areas with poor air quality.

[0045] A heating wire 22 is provided on the side of the fixed frame 11 away from the filter plate 21. The heating wire 22 is located between the filter plate 21 and the ventilation fan 9. The heating wire 22 can preheat the incoming air in a low-temperature environment, and then the air is sent into the seedling area by the ventilation fan 9 to maintain a suitable growth temperature, promote the rooting and sprouting of cuttings, and improve the survival rate. It is especially suitable for seedling cultivation in cold seasons or high-altitude areas.

[0046] As a preferred option, temperature and humidity monitoring devices can be installed inside the seedling area to facilitate corresponding adjustments.

[0047] The working process of this utility model is as follows: The operator turns on the stepper motor 10, and the output end of the stepper motor 10 drives the drive shaft 14 to rotate. Since the drive shaft 14 is fixedly connected to the center of one of the rotating disks 2, the rotating disk 2 rotates. The two rotating disks 2 are fixedly connected by a connecting rod 15 and will rotate synchronously. During the rotation, the gravity block 4 on the mounting block 3 moves outward under the action of centrifugal force, and the rotation trajectory of the seedling frame 5 is stabilized by the gravity balancing effect, so as to realize the periodic uniform speed rotation of the seedling frame 5. The operator can stand in a fixed position to perform operations such as soil filling and planting on the seedling frames 5 at different positions.

[0048] Outdoor use: When encountering strong light, rain, snow, or inclement weather, the servo motor 13 is activated, and its shaft output drives one of the threaded rods 16 to rotate. The two threaded rods 16 are linked by a sprocket and a synchronous chain 17. The nut pair 18 moves on the threaded rod 16, which drives the connecting block 19 to move, thereby pushing the moving frame 7 to move, causing the accordion cover 6 to unfold and form the top shading area.

[0049] For use inside greenhouses: Inside the greenhouse, the same operation can be used to unfold the pleated cover 6, allowing it to work with the support frame 1 to form an insulated, enclosed space. If ventilation is needed, simply turn on the ventilation fan 9. When shading is not required, reverse the start of the servo motor 13 to close the pleated cover 6.

[0050] When it is necessary to maintain the internal temperature of the seedling space, after the ventilation fan 9 is turned on, air enters from the air vent and is first filtered by the filter plate 21 to remove larger impurities. In a low-temperature environment, the heating wire 22 works to preheat the filtered air, and then the ventilation fan 9 sends the preheated air into the seedling area to ensure that the temperature is within a suitable range.

[0051] 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.
