[0002] Ajuga decumbens, scientific name Ajuga decumbens, is a common herbaceous plant that usually grows in moist grasslands, riverbanks or under forests. It likes a moist environment, but is also afraid of waterlogging, so good drainage is one of the key conditions for growing Ajuga. In the process of planting and managing Ajuga, in order to promote the healthy growth of the plant, increase yield and effectively prevent and control diseases and insect pests, special equipment or tools are used to evenly spray fertilizers and pesticides on the Ajuga in the form of atomization.

[0022] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0023] (1) The present invention provides a fertilizer atomizing spraying device for cultivating water spinach seeds. By adjusting the spraying angle between the atomizing nozzle and the soil hill slope to be within the range of 90°±5°, the atomized fertilizer and medicine can directly fall on the soil position between the soil hill slope and the adjacent water spinach. This can not only ensure that the fertilizer and medicine are evenly distributed on the soil surface, but also avoid excessive accumulation of local fertilizer and medicine to form runoff, which will lead to damage to the soil hill structure and affect the cultivation of water spinach. At the same time, by utilizing the effect of gravity, the fertilizer and medicine can be evenly infiltrated into the soil, avoiding the generation of runoff on the soil hill slope. While improving the firmness of the soil hill structure, the efficiency of the medicine and fertilizer being absorbed by the plant is increased. The fertilizer and medicine infiltrated into the soil will gradually concentrate around the root system, ensuring that the plant can effectively absorb them.

[0024] (2) When the Amaranthus chinensis is in the germination and seedling growth stage, the present invention sets the bracket into an elliptical shape so that the major axis of the elliptical bracket is perpendicular to the length direction of the soil mound. The position of the spray head on the major axis can be closer to perpendicular to the slope surface for spraying, thereby reducing the loss and accumulation of the spray liquid on the slope surface, improving the accuracy and uniformity of spraying, and reducing the dead angles and overlapping areas of spraying caused by improper spraying angles. At the same time, it also avoids the atomized medicine from being sprayed directly onto the adjacent Amaranthus chinensis rhizomes, which affects the cultivation of the adjacent Amaranthus chinensis, thereby improving the cultivation efficiency of Amaranthus chinensis as a whole.

[0025] (3) When the water caltrops are in the vegetative growth stage and the reproductive growth stage, the present invention adjusts the bracket to be close to a circle through the adjustment component, so that the atomizing nozzles can be evenly distributed around the center point to form a complete circular spraying range, which helps to ensure that each atomizing nozzle can cover the same area when spraying, and the overlapping area is small, thereby improving the uniformity of spraying, allowing the leaves to evenly absorb nutrients and maintain healthy growth.

[0026] (4) The present invention controls the support to change between an elliptical shape and a circular shape. By applying fertilizers to the Amaranthus in different states according to the different stages of Amaranthus cultivation, the fertilizer and pesticide atomizing spraying equipment can be used for spraying fertilizers and pesticides on seeds at different stages, thereby improving the Amaranthus cultivation efficiency and enabling the same equipment to adapt to different agricultural operating environments and needs.

[0027] (5) The present invention uses vertical spraying to evenly cover the slope of the soil mound with the drug, thus avoiding the situation where the local concentration is too high or too low, which is helpful for the balanced distribution of soil nutrients, promotes the activity of soil microorganisms, and further improves the soil structure and enhances the soil's ability to retain water and fertilizer. At the same time, the good soil environment also provides sufficient nutrients and water for the growth of Amaranthus, promotes the development of its root system and the growth of the aboveground part, and provides a stable growth environment for the root system of Amaranthus.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0039] In the process of cultivating Amaranthus seeds, Amaranthus seeds will go through different stages of growth, including: germination stage, seedling growth stage, vegetative growth stage, reproductive growth stage, and the fertilization methods for Amaranthus are also different at different stages;

[0040] During the germination and seedling growth stages of Amaranthus seeds, fertilizers and pesticides need to be applied to the soil around the roots of the Amaranthus seeds. During the germination and seedling growth stages of Amaranthus seeds, fertilizers and pesticides need to be applied directly to the leaves of the Amaranthus seeds.

[0041] Among them, the planting method of Amaranthus seeds is also different. In order to improve the growth efficiency of Amaranthus seeds, the "ridge-building" or "ridge-cultivation" farming method is used. Specifically, rows of earth mounds, i.e. ridges, are set up in the fields, and low-lying ditches are formed between the ridges. During irrigation or rainfall, excess water can be discharged along the ditches to avoid water accumulation and root diseases. At the same time, the soil structure of the earth mounds is relatively loose, which is conducive to air circulation and is beneficial to the root growth of Amaranthus.

[0042] In a preferred embodiment, the top width of the soil mound 14 is set to 30-32 cm, the bottom width is set to 60-62 cm, the height is set to 40-42 cm, the distance between each soil mound 14 is set to 40 cm, and the seeds planted in the soil mound 14 are evenly spaced 30-35 cm apart to ensure stability and easy penetration of the spray liquid.

[0043] like Figure 1 As shown, a fertilizer and medicine atomization spraying device for cultivating water spinach seeds includes: a cultivation platform 1, a mounting frame 2, a spraying component, an angle adjustment component and a control system 2; the mounting frame 2 is located above the cultivation platform 1, the mounting frame 2 is provided with a plurality of slide rails 3, the spraying component is installed at the position of the slide rails 3, and the four legs of the mounting frame 2 are hydraulic telescopic rods;

[0044] The cultivation platform 1 includes: a plurality of soil mounds 14 stacked in parallel; a plurality of slide rails 3 corresponding to the plurality of soil mounds 14 one by one, that is, the shape of the soil mounds 14 is a trapezoidal structure narrow at the top and wide at the bottom;

[0045] like Figure 2 and Figure 3 As shown, the spray assembly includes: a bracket 4, an atomizing nozzle 5, a material pipeline 7 and an airflow pipeline 8, wherein the atomizing nozzle 5 is specifically a "BEX dual-fluid atomizing nozzle 5"; a plurality of atomizing nozzles 5 are provided, and the plurality of atomizing nozzles 5 are evenly installed on the bracket 4, one end of the material pipeline 7 and the airflow pipeline 8 are both connected to the atomizing nozzle 5, the other end of the material pipeline 7 is provided with a material storage tank connected thereto, and the other end of the airflow pipeline 8 is provided with a high-pressure air pump connected thereto;

[0046] The control system 2 controls the support 4 to move on the slide rail 3, and a plurality of atomizing nozzles 5 on the support 4 cover the water chestnut seeds on the soil mound 14 with fertilizers and medicines.

[0047] During the cultivation process, Amaranthus needs to go through different stages such as germination and leafing. Different watering and covering methods are required for Amaranthus at different stages so that Amaranthus can absorb nutrients more efficiently. Therefore, an angle adjustment component is provided. A verticality sensor 18 is installed on the side of the atomizing nozzle 5 to monitor the verticality of the atomizing nozzle 5 and the slope in real time and transmit it to the control system 2. The control system 2 controls the angle adjustment component to adjust the angle between the atomizing nozzle 5 and the spraying surface. The control system 2 is used to control the movement, spraying amount, spraying time of the spraying component, and control the spraying angle of the atomizing nozzle 5.

[0048] The cultivation process of Amaranthus chinensis specifically includes: germination and seedling emergence stage, seedling growth stage, vegetative growth stage, and reproductive growth stage. In the germination and seedling growth stage, the soil near the rhizome of Amaranthus chinensis needs to be sprayed with drugs to avoid the drugs from damaging the rhizome of Amaranthus chinensis. The soil near the rhizome of Amaranthus chinensis includes: the slope position of the mound 14 and the soil between adjacent Amaranthus chinensis.

[0049] During the fertilization process, the angle adjustment component controls the angle of the atomizing nozzle 5, and the verticality sensor 18 detects the vertical angle between the atomizing nozzle 5 and the slope of the mound 14 in real time, and controls the angle between the atomizing nozzle 5 and the slope of the mound 14 to be within the range of 90°±5°, so that the liquid fertilizer is mixed with the air until it is atomized and sprayed on the slope of the mound 14, and the control system 2 controls the bracket 4 to move on the slide rail 3 to fertilize the slope of the mound 14. By fertilizing the slope of the mound 14 with atomized fertilizer, it can not only ensure that the fertilizer is evenly distributed on the soil surface, but also avoid excessive accumulation of local fertilizer to form runoff, resulting in damage to the structure of the mound 14 and affecting the cultivation of Amaranthus. At the same time, by using gravity, the fertilizer can be evenly penetrated into the soil, and the water molecules of the fertilizer will quickly combine with the soil of the mound 14 to increase the soil moisture and adhesion, prevent the soil from loosening and sliding, and maintain the integrity of the shape of the mound 14. In addition, the fertilizer infiltrated in the soil will gradually concentrate around the root system to ensure that the plant can effectively absorb it.

[0050] In the present invention, a plurality of slide rails 3 are provided with a connecting groove 9, and a driving assembly is provided in the connecting groove 9, and the driving assembly includes: a reciprocating screw rod 10, a nut seat 11 and a gear 12; the reciprocating screw rod 10 is rotatably installed in the connecting groove 9, and one end of the reciprocating screw rod 10 passes through the connecting groove 9, extends to the outside of the slide rail 3, and is coaxially fixed with the gear 12, and the nut seat 11 is threadedly connected with the reciprocating screw rod 10;

[0051] The surface of the slide rail 3 is provided with a moving groove for the end of the nut seat 11 to move, and the bracket 4 is connected to the end of the nut seat 11;

[0052] A toothed chain 13 is sleeved on the plurality of gears 12 , and the plurality of gears 12 are all meshed with the toothed chain 13 , and the gear 12 at one end thereof is driven to rotate by a motor.

[0053] A number of soil mounds 14 are arranged in a row, and a number of seeds are evenly distributed on the soil mounds 14, so it is necessary to drive the bracket 4 to move on the soil mounds 14 to fertilize the seeds evenly distributed on the soil mounds 14. The gear 12 fixed to the end thereof is driven by a motor to rotate, and the several gears 12 are meshed through a toothed chain 13. When one of the gears 12 rotates, the several gears 12 are meshed through the toothed chain 13, thereby rotating synchronously, driving the reciprocating screw 10 coaxially fixed with the gear 12 to rotate in the connecting groove 9, wherein the nut seat 11 is slidably connected to the connecting groove 9, and with the cooperation of the nut seat 11 and the reciprocating screw 10, the nut seat 11 is driven to move on the slide rail 3, and because the bracket 4 is fixed to the end of the nut seat 11, the bracket 4 is driven to move on the slide rail 3 to fertilize the soil mound 14.

[0054] In the present invention, considering that the water spinach is in the germination and seedling growth stage, it is necessary to spray medicine on the slope of the mound 14. In order to avoid the fertilizer and medicine affecting the adjacent water spinach during the fertilization process, the bracket 4 is set to an elliptical shape, and the two ends of the long axis of the bracket 4 extend to the slopes on both sides of the mound 14 respectively, further improving the angle between the atomizing nozzle 5 and the slope of the mound 14 to be closer to the vertical angle, so that the fertilizer and medicine can penetrate into the soil more directly, quickly reach the root system, and improve the efficacy and nutrient absorption efficiency.

[0055] In the present invention, Figure 4 As shown, the bracket 4 is made of rubber material, which provides a basis for subsequent deformation. A plurality of rotating grooves 15 are provided on the bracket 4, and a plurality of atomizing nozzles 5 are installed in the rotating grooves 15; an iron ring is provided in the rotating groove 15, and the angle adjustment component includes: a rotating rod 16 and a stepping motor 17; the rotating rod 16 is fixedly installed at the end position of the atomizing nozzle 5, and both ends of the rotating rod 16 are sleeved in the iron ring and rotatably connected with the rotating groove 15, and one end of the rotating rod 16 passes through the rotating groove 15 and is fixed to the output end of the stepping motor 17, and the stepping motor 17 drives the rotation angle of the atomizing nozzle 5;

[0056] The control system 2 controls the stepping motor 17 to drive the atomizing nozzle 5 to rotate at an angle.

[0057] The verticality sensor 18 detects the angle between the atomizing nozzle 5 and the slope of the soil mound 14 in real time. When the angle between the atomizing nozzle 5 and the slope of the soil mound 14 needs to be adjusted, the control system 2 controls the rotation angle of the output end of the stepper motor 17 through the real-time data of the verticality sensor 18. For example, after the verticality sensor 18 detects that the minimum angle between the atomizing nozzle 5 and the slope of the soil mound 14 is 70°, which is 20°±5° different from the predetermined angle between the atomizing nozzle 5 and the slope of the soil mound 14 of 90°±5°, the control system 2 controls the rotation angle of the stepper motor 17 so that the atomizing nozzle 5 rotates to the predetermined angle range;

[0058] The output end of the stepper motor 17 is coaxially fixed with the rotating rod 16, and the rotating rod 16 is fixed with the end of the atomizing nozzle 5. When the rotating rod 16 rotates, the atomizing nozzle 5 is driven to rotate in the rotating groove 15, so that the atomizing nozzle 5 rotates to a proper angle. The angle between the atomizing nozzle 5 and the slope of the soil mound 14 is within the range of 90°±5°, ensuring that the fertilizer directly acts on the soil of the soil mound 14, improving the utilization rate of the fertilizer, and at the same time, helping to reduce the flow of fertilizers and medicines on the slope, further reducing the loss of medicines, and ensuring the integrity of the shape of the soil mound 14;

[0059] Through vertical spraying, the drug can evenly cover the slope of the soil mound 14, avoiding the situation of excessively high or low local concentration, which is helpful for the balanced distribution of soil nutrients, promotes the activity of soil microorganisms, and thus improves the soil structure and enhances the soil's ability to retain water and fertilizer. At the same time, a good soil environment also provides sufficient nutrients and water for the growth of Amaranthus, promotes the development of its root system and the growth of the above-ground part, and provides a stable growth environment for the roots of Amaranthus.

[0060] In the present invention, the leaves of Amaranthus need to be sprayed with medicine during the vegetative growth stage and the reproductive growth stage. The long axis position of the elliptical bracket 4 is perpendicular to the extension direction of the soil mound 14. The two ends of the long axis of the elliptical bracket 4 are farther from the leaves than the short axis position. The atomizing nozzle 5 on the bracket 4 is at different lengths from the center of the leaves, which easily leads to the inability to spray fertilizers and medicines evenly on the leaves, so that the leaves cannot absorb fertilizers and medicines efficiently. Therefore, an adjustment component is set at the position of the bracket 4 to adjust the shape of the bracket 4;

[0061] like Figure 5 As shown, a shape adjustment component is provided on the bracket 4, and the shape adjustment component includes: a fixing plate 26, a connecting frame 19, a threaded rod 20, a first bevel gear 21 and a driving part;

[0062] There are several connecting frames 19, including: a first connecting rod 22, a second connecting rod 23 and a connecting block 24; the first connecting rod 22 and the second connecting rod 23 are both hinged to the connecting block 24, and the first connecting rod 22 and the second connecting rod 23 are symmetrically arranged, and a threaded groove is opened in the middle of the connecting block 24;

[0063] The center position of the fixing plate 26 is fixedly connected to the end of the nut seat 11, and a plurality of connecting blocks 24 are symmetrically installed on the bottom surface of the fixing plate 26. The connecting blocks 24 are slidably connected to the fixing plate 26. The threaded rod 20 is installed in the thread groove of the connecting block 24. The first bevel gear 21 is located in the middle of the threaded rod 20 and is coaxially fixed to the threaded rod 20. Both ends of the threaded rod 20 are rotatably connected with connecting plates, and the connecting plates are fixedly connected to the fixing plate 26. The threads on the threaded rod 20 on both sides of the first bevel gear 21 are symmetrically arranged, that is, reverse threads.

[0064] The driving unit drives the first bevel gear 21 to rotate, and the driving unit includes: a second bevel gear 25 and a servo motor 6; the second bevel gear 25 is coaxially fixed with the output end of the servo motor 6, and the second bevel gear 25 is meshed with the first bevel gear 21;

[0065] When spraying fertilizers on the leaves of the water spinach, the bracket 4 is adjusted to be close to a circle by adjusting the assembly. The servo motor 6 needs to be controlled to drive the second bevel gear 25 to rotate in a clockwise direction, driving the meshing first bevel gear 21 to rotate. The first bevel gear 21 is fixedly installed in the middle position of the threaded rod 20, and the threaded rod 20 will rotate synchronously with the first bevel gear 21. The connecting block 24 threadedly connected to the threaded rod 20 moves in a direction away from the first bevel gear 21. Because the first connecting rod 22 and the second connecting rod 23 are hinged at the position where they contact the bracket 4, As the connecting block 24 moves away from the first bevel gear 21, the angle between the first connecting rod 22 and the second connecting rod 23 gradually approaches 180°, so that the elliptical bracket 4 is adjusted and deformed until it approaches a circular bracket 4. The circular bracket 4 is designed to allow the atomizing nozzles 5 to be evenly distributed around the center point to form a complete circular spraying range, which helps to ensure that each atomizing nozzle 5 can cover the same area when spraying, and there is less overlapping area, thereby improving the uniformity of spraying, allowing the leaves to evenly absorb nutrients and maintain healthy growth.

[0066] In a preferred embodiment of the present invention, the control system 2 controls the operation of the servo motor 6 and the motor.

[0067] Embodiment 1:

[0068] In this embodiment, the Amaranthus is set on a cultivation platform, and the cultivation platform specifically adopts a "ridge-forming" or "ridge-cultivation" farming method, specifically, by setting rows of earth mounds in the field, the earth mounds are narrow at the top and wide at the bottom, the top width is set to 30-32cm, the bottom width is set to 60-62cm, the height is set to 40-42cm, and the distance between each earth mound 14 is set to 40cm, and the Amaranthus seeds are evenly sown on the earth mounds at a spacing of 30-35cm.

[0069] In the germination and seedling growth stages of Amaranthus seeds, it is necessary to spray the soil near the rhizomes of Amaranthus, wherein the soil near the rhizomes of Amaranthus includes: the slope of the mound 14 and the soil between adjacent Amaranthus. Therefore, an elliptical bracket is used. The reason is that due to the spacing limit between seeds on the mound, if a circular bracket is used, its diameter must be smaller than the spacing between adjacent seeds, and the maximum angle between the spray direction of the atomizing nozzle and the mound slope is always small, much less than 90°. However, if an elliptical bracket with a long axis perpendicular to the length direction of the mound is used, the maximum angle between the spray direction of the atomizing nozzle and the mound slope is close to 90°. Although the upper half of the mound slope can be sprayed with fertilizers and medicines, the diameter of the circular bracket is limited, which helps to reduce the flow of fertilizers and medicines on the slope and improve the absorption of the Amaranthus roots.

[0070] In the initial state, the wide axis distance of the elliptical bracket is 20-22.5cm, the ratio of the long axis to the wide axis of the elliptical bracket is 1.5-2:1, and the angles of the atomizing nozzles at both ends of the long axis of the elliptical bracket and the slope of the mound are set to spray the medicine atomized on the upper half of the slope of the mound and the soil between adjacent amaranths.

[0071] When the Amaranthus chinensis grows to the germination and seedling growth stages, it is necessary to spray the leaves of the Amaranthus chinensis with drugs, control the shape of the bracket and the rotation angle of the atomizing nozzle, and deform the elliptical bracket into a circular bracket. The reason is that the circular bracket design allows the atomizing nozzle to be evenly distributed around the center point to form a complete circular spraying range, while the spraying range of the atomizing nozzle at the long axis end of the elliptical bracket is far away from the leaves, and the spraying range of the atomizing nozzle at the short axis end is close to the leaves, so the leaves cannot be evenly sprayed with drugs;

[0072] When the elliptical bracket is deformed into a circular bracket, the length of the wide axis of the elliptical bracket will be deformed to 28.5-32cm, and the ratio of the long axis to the wide axis of the elliptical bracket approaches 1:1, that is, the elliptical bracket is deformed to approach a circular bracket to spray the leaves of the water spinach.

[0073] When the present invention is used, during the germination and seedling growth stages, it is necessary to spray the soil near the rhizomes of Amaranthus chinensis with medicine. The shape of the bracket 4 at this time is elliptical. The verticality sensor 18 detects the angle between the atomizing nozzle 5 and the slope of the mound 14 in real time and transmits it to the control system 2. The control system 2 controls the rotation angle of the output end of the stepper motor 17 through the real-time data of the verticality sensor 18. The output end of the stepper motor 17 is coaxially fixed with the rotating rod 16. The rotating rod 16 is fixed with the end of the atomizing nozzle 5. When the rotating rod 16 rotates, the atomizing nozzle 5 is driven to rotate in the rotating groove 15, so that the atomizing nozzle 5 rotates to an appropriate angle. The angle between the atomizing nozzle 5 and the slope of the mound 14 is in the range of 90°±5°. Inside, the motor drives the gear 12 fixed to the end thereof to rotate, and the several gears 12 are meshed through the tooth chain 13. When one of the gears 12 rotates, the several gears 12 mesh with the tooth chain 13, thereby rotating synchronously, driving the reciprocating screw 10 coaxially fixed with the gear 12 to rotate in the connecting groove 9, wherein the nut seat 11 is slidably connected with the connecting groove 9, and under the cooperation of the nut seat 11 and the reciprocating screw 10, the nut seat 11 is driven to move on the slide rail 3, because the bracket 4 is fixed to the end of the nut seat 11, the bracket 4 is driven to move on the slide rail 3, and the atomizing nozzle 5 on the bracket 4 sprays the liquid fertilizer and the air mixed into the atomized fertilizer on the slope position of the soil mound 14 and the soil between the adjacent water chestnuts;

[0074] When the Amaranthus is in the vegetative growth stage and the reproductive growth stage, it is necessary to spray the leaves of the Amaranthus with medicine. The control system 2 controls the servo motor 6 to drive the second bevel gear 25 to rotate in a clockwise direction, driving the meshing first bevel gear 21 to rotate. The first bevel gear 21 is fixedly installed in the middle position of the threaded rod 20, and the threaded rod 20 will rotate synchronously with the first bevel gear 21. The connecting block 24 threadedly connected to the threaded rod 20 moves in the direction away from the first bevel gear 21. Because the first connecting rod 22 and the second connecting rod 23 are hinged at the position where they contact the bracket 4, when the connecting block 24 moves in the direction away from the first bevel gear 21, the angle between the first connecting rod 22 and the second connecting rod 23 gradually approaches 180°, so that the elliptical bracket 4 is adjusted and deformed until it approaches a circular bracket 4. The atomizing nozzle 5 on the bracket 4 sprays the atomized fertilizer mixed with liquid fertilizer and air on the leaves of the Amaranthus.

Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
