Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal herb cultivation and seedling raising technology, specifically to a Chinese medicinal herb cultivation and seedling raising equipment. Background Technology

[0002] Traditional Chinese medicinal herb cultivation and seedling raising equipment refers to devices specifically designed for the centralized cultivation of seeds or seedlings of traditional Chinese medicinal herbs during the seedling stage. Currently, most traditional Chinese medicinal herb seedling cultivation relies on traditional multi-layer cultivation racks for management. Fertilization, as a crucial step in the seedling process, is typically achieved by applying water-soluble fertilizers through spraying.

[0003] Currently, many traditional Chinese medicinal herb seedling cultivation devices use a single nozzle above or to one side of the seedling area for fertilization. This single-point or localized fertilization method easily leads to uneven distribution of water-soluble fertilizer in the substrate. The fertilizer concentration is too high in the area near the nozzle, while the area far from the nozzle is in a state of nutrient deficiency. This uneven fertilization can easily affect the healthy growth of seedlings, resulting in uneven growth among seedlings of the same batch. On the other hand, the plant morphology of medicinal herbs changes from sowing to seedling stage. In the early stage, the root system is weak and the crown is small, requiring small-scale fertilization. In the middle and later stages, the root system expands and the branches and leaves are lush, requiring a larger coverage area and higher nutrient supply. However, the plant growth position and fertilization coverage area of ​​existing equipment are statically set, which is inconvenient to automatically adjust with the plant growth stage. When the plant crown expands, it can easily cause a decrease in nutrient absorption efficiency, thereby affecting the plant growth. Summary of the Invention

[0004] The purpose of this invention is to provide a Chinese medicinal herb planting and seedling cultivation device to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a Chinese medicinal herb planting and seedling cultivation device, comprising a connecting frame and a base plate installed inside the connecting frame. A first screw is installed in each of the two longitudinal and transverse through slots at the top of the base plate via a motor. Multiple guide rails slide longitudinally along the inner side of the upper end of the base plate. These guide rails are interconnected via telescopic connecting rods. Multiple pull blocks slide laterally on each of the guide rails. These pull blocks are interconnected longitudinally via telescopic connecting rods and sliding rods. The first guide rail at the front is threadedly connected to the longitudinal first screw, and the first pull block on the rear right side is threadedly connected to the transverse first screw. A connecting plate is installed on the top of each of the longitudinally arranged pull blocks on the right side, and a seedling box is installed on the top of the remaining pull blocks. A limiting plate is installed on the rear top of the seedling box. A cover is slidably arranged above the seedling box. The cover is slidably connected to the limiting plate through a rear protrusion. The cover is connected to the seedling box through an adjustment component. An inner slide rail slides vertically in the annular groove at the bottom of the cover through a spring. An outer slide rail is fixedly connected to the outside of the inner slide rail through a connecting rod. Multiple top blocks are fixedly connected to the inner side of the adjacent side of the inner and outer slide rails. A fertilizer application component is arranged between the inner and outer slide rails.

[0006] Preferably, the fertilization assembly includes a mounting block, a protruding post, and a toothed ring. The mounting block is disposed between the inner and outer slide rails. The toothed ring is installed on the upper part of the inner cavity of the cover. The mounting block is slidably mounted in the inner groove of the toothed ring. Both ends of the cavity below the mounting block are slidably connected to abutments by springs. The two abutments are slidably connected to the top block. The adjacent sides of the two abutments are slidably connected to the protruding post. A rotating ball rod is fixedly connected to the lower end of the protruding post. The rotating ball rod is movably mounted through the bottom of the inner side of the mounting block. A fertilizer spraying pipe is fixed to the bottom end of the rotating ball rod. A first gear is rotatably connected to the top cavity of the mounting block by a motor. The outer side of the first gear meshes with the inner teeth of the toothed ring.

[0007] Preferably, the inner wall of the cover has openings at equal angles around its circumference, and the openings in the inner wall of the cover are used for the outer slide rail to slide vertically inside the cover. A light mounting base is installed at the center of the bottom end of the cover.

[0008] Preferably, the top block inside the inner slide rail and the top block inside the outer slide rail are staggered at equal angles along the circumference. The top block is designed as a semi-conical structure and is used to abut against the block at different amplitudes.

[0009] Preferably, the outer port of the fertilizer spraying pipe is connected to an external fertilizer supply device via a flexible hose, and the fertilizer spraying pipe is inclined toward the center of the seedling box.

[0010] Preferably, the adjusting assembly includes a second screw, which is rotatably mounted on the front edge of the seedling box. A second gear is fixedly connected to the outer side of the second screw, and the teeth of the second gear mesh with a rack. A first actuating plate is fixedly connected to the outer side of the limiting plate. A second actuating plate is abutted against the front side of the first actuating plate. The second actuating plate is slidably mounted in the through hole of the protrusion at the rear of the cover. The outer side of the second screw is threadedly connected to the protrusion at the front of the cover.

[0011] Preferably, a single rack is installed on the front side of the adjacent seedling box on the right, and the rightmost rack is fixed on the front side of the connecting plate.

[0012] Preferably, the contact surfaces of the first actuating plate and the second actuating plate are designed as inclined structures. The inclined structure of the first actuating plate is used for adjusting the position of the second actuating plate. The contact surface of the second actuating plate and the inner slide rail is designed as an inclined structure. The second actuating plate is used for adjusting the vertical position of the inner slide rail.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, after the motor inside the fertilization assembly is connected, the first gear meshes with the gear ring and rolls around the gear ring, thereby driving the mounting block and the fertilizer spraying pipe to make uniform circular motion around the seedling box. This reduces the dead angle of fertilization caused by the fixed fertilization angle. During the circular motion of the fertilizer spraying pipe, the abutment block is periodically squeezed by the staggered top block, which drives the fertilizer spraying pipe to swing, thereby changing the fertilization tilt angle of the fertilizer spraying pipe and realizing the dynamic adjustment of the tilt angle of the fertilizer spraying pipe, improving the uniformity of fertilization. In this process, the abutment block only contacts the lower and thinner section of the top block, the swing angle of the fertilizer spraying pipe is small, and the fertilizer is concentrated and sprayed in the core area of ​​the plant roots.

[0015] 2. In this invention, through the fertilization component and the adjustment component, when the spatial position between multiple plants is adjusted according to the growth volume of the plants, two motors drive two first screws to rotate, causing multiple guide rails to slide longitudinally on the base plate through telescopic connecting rods. At the same time, multiple pull blocks slide laterally on the guide rails through telescopic connecting rods, so that the gap between multiple seedling boxes is adjusted accordingly, always providing sufficient growth space for each Chinese herbal medicine seedling, preventing overcrowding and poor ventilation in the later stages of planting, which would affect the healthy growth of the plants. During this process, the moving rack meshes with and drives the second gear to rotate, which in turn drives the second screw to rotate, thereby causing the cover to rise and fall. When the cover rises, the vertical displacement of the second actuating plate is converted into a downward pushing force on the top of the inner slide rail through the inclined surface action of the first and second actuating plates, forcing the inner and outer slide rails to move down synchronously. At this time, the block contacts the larger upper part of the top block during the movement, which generates a greater lateral pushing force, causing the deflection angle of the fertilizer spraying pipe to increase, thereby automatically expanding the coverage radius of fertilizer spraying to match the expansion of the plant crown.

[0032] 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.

[0033] Example 1

[0034] Please see Figures 1 to 15This invention provides a technical solution: a Chinese medicinal herb planting and seedling raising device, including a connecting frame 1 and a base plate 2 installed inside the connecting frame 1. Two longitudinal and transverse through slots at the top of the base plate 2 are each equipped with a first screw 3 via a motor. Multiple guide rails 5 slide longitudinally along the inner side of the upper end of the base plate 2, and the multiple guide rails 5 are interconnected via telescopic connecting rods. Multiple pull blocks 4 slide laterally on each of the multiple guide rails 5, and the multiple pull blocks 4 are interconnected longitudinally via telescopic connecting rods and sliding rods. The first guide rail 5 at the front is threadedly connected to the longitudinal first screw 3, and the first pull block 4 at the rear right is threadedly connected to the transverse first screw 3. A connecting plate is installed at the top of each of the rightmost longitudinal pull blocks 4, and a seedling box 6 is installed at the top of the remaining pull blocks 4. A limiting plate 7 is installed at the rear top of the seedling box 6. A cover 8 slides above the seedling box 6, and the cover 8 is slidably connected to the limiting plate 7 via a rear protrusion. The cover 8 is connected to the seedling box 6 via an adjusting component 13. An annular groove at the bottom of the cover 8 is used for... The spring slides vertically along an inner slide rail 9. An outer slide rail 10 is fixedly connected to the outside of the inner slide rail 9 via a connecting rod. Multiple top blocks 11 are fixedly connected to the inner sides of adjacent surfaces of the inner and outer slide rails 10. A fertilizer assembly 12 is installed between the inner and outer slide rails 9 and 10. Multiple seedling boxes 6 are installed side by side above the base plate 2. Each seedling box 6 is supported by a corresponding pull block 4. Chinese medicinal herbs are sown in each seedling box 6. At this time, the seedlings are small, and the multiple seedling boxes 6 are close together. The cover 8 is in a low position to promote seed germination and initial growth. As the Chinese medicinal herbs seedlings gradually grow, two motors are started to drive two first screws 3 to rotate. One first screw 3 drives the pull block 4 to move horizontally, and the other first screw 3 drives the guide rail 5 to move vertically. During this process, the distance between the multiple seedling boxes 6 gradually increases, always providing sufficient growth space for each Chinese medicinal herb seedling and preventing overcrowding and poor ventilation in the later stages of planting, which would affect the healthy growth of the plants.

[0035] Fertilizer applicator 12 includes a mounting block 121, a protruding post 124, and a toothed ring 126. The mounting block 121 is positioned between the inner slide rail 9 and the outer slide rail 10. The toothed ring 126 is mounted on the upper part of the inner cavity of the cover 8. The mounting block 121 is slidably mounted in the inner groove of the toothed ring 126. Both ends of the cavity below the mounting block 121 are slidably connected to abutments 122 by springs. The two abutments 122 are slidably connected to the top block 11. The adjacent side of the two abutments 122 is slidably connected to the protruding post 124. A rotating ball rod 123 is fixedly connected to the lower end of the protruding post 124. The rotating ball rod 123 is movably mounted through the bottom of the inner side of the mounting block 121. A fertilizer spraying pipe 125 is fixed to the bottom end of the rotating ball rod 123. A first gear 127 is rotatably connected to the top cavity of the mounting block 121 by a motor. The outer side of the first gear 127 is connected to the toothed ring 126. When the internal gears of the 26 gears mesh, after the motor in the top cavity of the mounting block 121 is started, the first gear 127 rolls around the tooth ring 126, thereby driving the entire mounting block 121 to move in a circular motion around the seedling box 6 along the annular path between the inner slide rail 9 and the outer slide rail 10. The fertilizer spraying pipe 125 moves synchronously around the mounting block 121, realizing all-round and continuous water-soluble fertilizer spraying on the Chinese medicinal seedlings in the seedling box 6, avoiding local over-fertilization or omission. The inner slide rail 9 and the outer slide rail 10 are provided with top blocks 11. When the abutment block 122 contacts the top block 11 during the sliding process, it is subjected to radial thrust, compresses the spring and squeezes the protrusion 124 inward. After the protrusion 124 is subjected to force, it drives the rotating ball 123 to deflect, thereby changing the fertilizer spraying pipe 125's fertilization tilt angle, realizing dynamic adjustment of the fertilizer spraying pipe 125's tilt angle, and improving the uniformity of fertilization.

[0036] The inner wall of the cover 8 has openings at equal angles around its circumference. The openings in the inner wall of the cover 8 are used for the outer slide rail 10 to slide vertically inside the cover 8. A light mounting base is installed at the center of the bottom of the cover 8. The light mounting base is used to install LED plant growth lights to provide a vertical and uniform lighting environment for the Chinese medicinal seedlings.

[0037] The top block 11 inside the inner slide rail 9 and the top block 11 inside the outer slide rail 10 are staggered at equal angles along the circumference. The top block 11 is designed as a semi-conical structure. The top block 11 is used to abut the block 122 at different amplitudes. During the sliding process of the block 122, due to the staggered arrangement of the top blocks 11 inside the inner slide rail 9 and the outer slide rail 10, the block 122 alternately contacts the top block 11 inside the inner slide rail 9 or the outer slide rail 10, so that the fertilizer spraying pipe 125 undergoes multiple angle adjustments in different directions during one rotation, forming a dynamically changing spraying pattern.

[0038] The outer port of the fertilizer spraying pipe 125 is connected to an external fertilizer supply device via a flexible hose. The fertilizer spraying pipe 125 is inclined towards the center of the seedling box 6. The entire fertilizer spraying pipe 125 is inclined towards the center of the seedling box 6, that is, the nozzle of the fertilizer spraying pipe 125 points towards the root area of ​​the plant, so that the water-soluble fertilizer is concentrated on the core area of ​​seedling growth and improves the fertilizer utilization rate.

[0039] Example 2

[0040] Based on Example 1, please refer to Figures 1 to 15 The adjusting assembly 13 includes a second screw 131, which is rotatably mounted on the front edge of the seedling box 6. A second gear 132 is fixedly connected to the outer side of the second screw 131, and the teeth of the second gear 132 mesh with a rack 133. A first actuating plate 134 is fixedly connected to the outer side of the limiting plate 7, and a second actuating plate 135 is abutted against the front side of the first actuating plate 134. The second actuating plate 135 is slidably mounted in the through hole of the protrusion at the rear of the cover 8. The outer side of the second screw 131 is threadedly connected to the protrusion at the front of the cover 8. The rack 133 drives the second gear 132 to rotate, thereby... When the second screw 131 rotates, the cover 8 moves up or down outside the limiting plate 7 via the slider on its outer side, thus adjusting the height of the cover 8. When the cover 8 rises, it drives the second actuating plate 135 to move upward together. Since the first actuating plate 134 is fixed, the second actuating plate 135 is forced to slide along the contact surface of the first actuating plate 134. This movement converts the vertical displacement of the second actuating plate 135 into a downward pushing force on the top of the inner slide rail 9, forcing the inner slide rail 9 to overcome the spring force and move downward. The inner slide rail 9 is connected to the outer slide rail 10 via a connecting rod, therefore the outer slide rail 10... 0 also moves downwards synchronously. In the early stage of plant growth, the cover 8 is in a lower position, while the inner slide rail 9 and outer slide rail 10 are in a higher position. Since the top block 11 is designed with a semi-conical structure, at this time, the abutment block 122 only contacts the lower, thinner section of the top block 11 during the circular movement. Due to the low contact height and short thrust arm, the lateral force generated on the convex column 124 is small, the deflection angle of the rotating ball 123 is limited, and the fertilizer spraying pipe 125 only swings slightly. This is suitable for the stage when seedlings are dense and the crown is small. As the medicinal herb seedlings continue to grow taller, the adjusting component 13 is activated, causing the cover 8 to rise. Simultaneously, the inner slide rail 9 and the outer slide rail 10 move downwards synchronously through the first actuating plate 134 and the second actuating plate 135. When the abutment block 122 moves to the position of the top block 11 again, it contacts the thicker upper section. At this time, the horizontal thrust generated on the abutment block 122 is greater. After the abutment block 122 is subjected to this stronger thrust, it squeezes the protruding column 124 more significantly, driving the rotating ball 123 to produce a larger deflection angle. This expands the swing range of the spray direction of the fertilizer spraying pipe 125, making it easier for the water-soluble fertilizer to cover a wider area of ​​the plant canopy, adapting to the growth form of the plant in the middle and late stages when the branches and leaves are spread out and widely distributed.

[0041] A single rack 133 is installed on the front side of the adjacent seedling box 6 on the right. The rightmost rack 133 is fixed on the front side of the connecting plate. When the seedling box 6 moves laterally, the rack 133 on it moves accordingly, thereby driving the second gear 132 of the previous seedling box 6 to rotate, which in turn drives the second screw 131 of the previous seedling box 6 to rotate, so as to adjust the height of the cover 8.

[0042] The contact surfaces of the first actuating plate 134 and the second actuating plate 135 are designed as inclined surfaces. The inclined surface of the first actuating plate 134 is used for adjusting the position of the second actuating plate 135. The contact surface of the second actuating plate 135 and the inner slide rail 9 is designed as inclined surfaces. The second actuating plate 135 is used for adjusting the vertical position of the inner slide rail 9.

[0043] Working principle: During the sowing and initial seedling stage, multiple seedling boxes 6 are installed side by side on the base plate 2, supported by corresponding pull blocks 4. At this time, the two first screws 3 are in the initial position, the multiple pull blocks 4 are close to the guide rail 5, the seedling boxes 6 are closely spaced, and the cover 8 is in the lowest position, forming a relatively sealed environment, which is conducive to heat preservation and promotes seed germination and early seedling growth. When fertilization is needed, the motor in the top cavity of the mounting block 121 is started, driving the first gear 127 to rotate. The first gear 127 meshes with the gear ring 126 fixed at the bottom of the cover 8, thereby driving the entire mounting block 121 to make uniform circular motion around the center of the seedling box 6. The fertilizer spraying pipe 125 at the bottom of the mounting block 121 rotates synchronously, spraying fertilizer towards the seedling area in the center of the seedling box 6. Continuous, circumferential water-soluble fertilizer spraying reduces fertilization dead zones. When the mounting block 121 rotates, two abutment blocks 122 connected by springs on both sides slide along the inner slide rail 9 and the outer slide rail 10 respectively. The top blocks 11, which are staggered inside the inner slide rail 9 and the outer slide rail 10, periodically squeeze the abutment blocks 122. The abutment blocks 122 are compressed and push the protrusion 124, forcing the rotating ball 123 to deflect. This causes the fertilizer spraying pipe 125 to undergo multiple angle deflections during each rotation, forming a dynamic spraying mode, which greatly improves the uniformity of fertilization. During this process, the abutment blocks 122 only contact the lower, thinner section of the top block 11, and the fertilizer spraying pipe 125 swings at a small angle, so that the fertilizer is concentrated in the core area of ​​the plant roots.

[0044] As the seedlings of Chinese medicinal herbs grow, they require more growing space to avoid overcrowding. Two motors mounted on the base plate 2 are activated. One motor drives the first screw 3 connected to it to rotate, causing all the pull blocks 4 to move laterally. The other motor drives another first screw 3 to rotate, causing all the guide rails 5 to move vertically. This gradually increases the spacing between all the seedling boxes 6, ensuring that each medicinal herb receives sufficient ventilation space throughout the entire seedling cycle. When the seedling box 6 moves laterally due to the spacing adjustment, the rack 133 fixed to its side moves synchronously. The moving rack 133 meshes with and drives the second gear 132 on the adjacent seedling box 6 to rotate, thereby driving the... The second screw 131 rotates, driving the cover 8 to move upward along the limiting plate 7. When the cover 8 rises, the first actuating plate 134 fixed on the outside of the limiting plate 7 forces the second actuating plate 135, which is in cooperation with the inclined surface, to produce a lateral displacement. The second actuating plate 135 then converts this displacement into a downward pushing force on the top of the inner slide rail 9 through another inclined surface. The inner slide rail 9 is compressed to overcome the elastic force of the spring, driving the outer slide rail 10, which is fixed by the connecting rod, to move downward together. At this time, the abutment block 122 will contact the thicker upper part of the top block 11, and the pushing force is greater, which causes the deflection angle of the fertilizer spraying pipe 125 to increase, so that the fertilizer spraying can cover a wider crown area to adapt to the plant shape with spreading branches and leaves.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
