Technical Field
[0001] This utility model relates to the field of sweet orange cultivation, and in particular to an energy-saving spray fertilization device for sweet orange cultivation. Background Technology
[0002] Sweet orange is a tree belonging to the Rutaceae family and the Citrus genus. Its branches have few or almost no thorns. Its leaves are slightly smaller than those of grapefruit, with narrow and long winged leaves. The leaves are ovate or ovate-elliptic, rarely lanceolate. The flowers are white, with a few flowers having a pale purplish-red back. The fruit is round, oblate, or elliptic, ranging in color from orange-yellow to orange-red. Sweet oranges require fertilization at different stages throughout their entire growth cycle, from seedling to mature plant.
[0003] When fertilizing sweet oranges, soluble fertilizers are prepared into liquid and then sprayed evenly onto the branches, leaves, and roots of the plants. To improve fertilization efficiency and fertilizer utilization in sweet orange cultivation, spray fertilization equipment is used. However, traditional spray fertilization devices for sweet orange cultivation have some shortcomings in practical applications. The sprayers of traditional devices are mostly fixed and their height cannot be adjusted. When spraying sweet orange seedlings, the height is often too high, leading to fertilizer waste. In the mature stage, the height is insufficient to cover the top of the canopy, requiring manual lifting of the sprayer, which increases labor intensity. Some manual adjustment devices have low adjustment accuracy and poor stability after adjustment, making them prone to shaking during spraying and having poor adaptability. Therefore, we propose an energy-saving spray fertilization device for sweet orange cultivation to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an energy-saving spray fertilization device for sweet orange cultivation, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An energy-saving spray fertilization device for sweet orange cultivation includes a movable base, a fertilizer storage tank fixedly connected to the upper surface of the movable base, a stirring mechanism installed inside the fertilizer storage tank, a sprayer on one side of the fertilizer storage tank, and a height adjustment mechanism for adjusting the vertical movement of the sprayer below the sprayer.
[0006] The height adjustment mechanism includes a fixed frame fixedly connected to a movable base, two side rails fixedly connected to the fixed frame, and guide plates slidably connected to each side rail. The top ends of the multiple guide plates are fixedly connected to a mounting base. The sprayer is mounted on the mounting base. A servo motor is installed on the inner wall of the fixed frame. An adjusting screw is fixedly connected to the output end of the servo motor. A threaded sleeve is threadedly connected to the outer surface of the adjusting screw. Two transmission rods are fixedly connected to the upper surface of the threaded sleeve. The top end of each transmission rod passes through the fixed frame and is connected to the mounting base.
[0007] In a further embodiment, the bottom surface of the movable base is equipped with multiple casters, and the upper surface of the movable base is fixedly connected to a push rod located on one side of the fertilizer storage tank.
[0008] In a further embodiment, a pump body is mounted on the upper surface of the movable base. The input end of the pump body is connected to the fertilizer storage tank, and the output end of the pump body is fixedly connected to a flexible infusion tube. One end of the flexible infusion tube is connected to a sprayer.
[0009] In a further embodiment, the height adjustment mechanism further includes two guide grooves formed within the fixed frame, and both ends of the threaded sleeve are slidably connected to the interior of the corresponding guide grooves.
[0010] In a further embodiment, the stirring mechanism includes a drive motor fixedly connected to the fertilizer storage tank, a transmission shaft fixedly connected to the output end of the drive motor, a plurality of auxiliary stirring blades and a plurality of main stirring blades fixedly connected to the transmission shaft, and the auxiliary stirring blades are located inside the main stirring blades.
[0011] In a further embodiment, the stirring mechanism further includes a paddle seat fixedly connected to the bottom end of the drive shaft, and the bottom end of each main stirring paddle is connected to the paddle seat.
[0012] In a further embodiment, the fertilizer storage tank has two lids at the top, and a filter screen is fixedly connected to the inner wall of the fertilizer storage tank, with the filter screen located below the stirring mechanism.
[0013] Compared with the prior art, the beneficial effects of this utility model are: The servo motor of the height adjustment mechanism drives the adjustment screw to rotate. The threaded sleeve plate drives the mounting base to rise and fall smoothly along the side rail and guide plate through the transmission rod. The sprayer height can be precisely adjusted according to the age of the sweet orange tree, seamlessly adapting from the low height of the seedling stage to the high height of the mature tree stage. No manual lifting is required, reducing labor intensity. It can precisely adjust the spraying height to adapt to the entire planting cycle. Moreover, the main and auxiliary mixing paddles of the mixing mechanism form a two-stage mixing. The main paddle drives the overall flow of the solution, while the auxiliary paddle disperses locally deposited fertilizer particles.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-5 In this utility model, an energy-saving spray fertilization device for sweet orange planting includes a movable base 1, a fertilizer storage tank 4 is fixedly connected to the upper surface of the movable base 1, a stirring mechanism 5 is installed inside the fertilizer storage tank 4, a sprayer 7 is provided on one side of the fertilizer storage tank 4, and a height adjustment mechanism 6 for adjusting the up and down movement of the sprayer 7 is provided below the sprayer 7. The height adjustment mechanism 6 includes a fixed frame 61 fixedly connected to the movable base 1, two side rails 9 fixedly connected to the fixed frame 61, and guide plates 10 slidably connected to each side rail 9. The tops of the multiple guide plates 10 are fixedly connected to a mounting base 11. The sprayer 7 is mounted on the mounting base 11. A servo motor 62 is installed on the inner wall of the fixed frame 61. An adjusting screw 63 is fixedly connected to the output end of the servo motor 62. A threaded sleeve 64 is threadedly connected to the outer surface of the adjusting screw 63. Two transmission rods 65 are fixedly connected to the upper surface of the threaded sleeve 64. The top of each transmission rod 65 passes through the fixed frame 61 and is connected to the mounting base 11. The height adjustment mechanism 6 achieves precise lifting and lowering of the sprayer 7 through servo drive and guide rails. The stirring mechanism 5 ensures uniform fertilizer dissolution. The movable base 1 supports all components to form an integrated device, solving the core problems of fixed spray height and uneven fertilizer mixing in traditional devices, while taking into account adaptability and practicality.
[0018] Multiple casters 2 are mounted on the bottom of the mobile base 1. A push rod 3 located on one side of the fertilizer storage tank 4 is fixedly connected to the upper surface of the mobile base 1. The casters 2 are mounted on the bottom surface of the mobile base 1 and feature a large-diameter anti-slip design, suitable for muddy and rugged orchard surfaces. They can be easily moved by a single person, avoiding the problems of traditional devices getting stuck or requiring much effort to move. The push rod 3 is ergonomically designed for comfortable grip and allows for precise control of the device's direction when pushing, facilitating movement among the orange vines. A pump body 12 is mounted on the upper surface of the mobile base 1. The input end of the pump body 12 is connected to the fertilizer storage tank 4, and the output end of the pump body 12 is fixedly connected to a flexible infusion tube 13. One end of the flexible infusion tube 13 is connected to a sprayer 7. The pump body 12 provides stable power to precisely deliver the fertilizer solution in the fertilizer storage tank 4. The fluid is delivered to the sprayer 7, ensuring stable supply pressure and uniform spraying. The flexible infusion tube 13 has good flexibility, allowing it to freely extend, retract, and bend as the sprayer 7 rises and falls with the height adjustment mechanism 6. This avoids the problems of twisting, breaking, or interruption of fluid supply that occur with traditional rigid infusion tubes. The height adjustment mechanism 6 also includes two guide grooves 66 located within the fixed frame 61. Both ends of the threaded sleeve 64 are slidably connected to the interior of the corresponding guide grooves 66. The guide grooves 66 provide guidance for the threaded sleeve 64, and together with the longitudinal guidance of the side rail 9 and the guide plate 10, form a bidirectional guiding structure. This ensures that the threaded sleeve 64 moves smoothly under the drive of the adjusting screw 63, preventing height adjustment from getting stuck or jammed due to the tilt of the threaded sleeve 64. At the same time, it disperses the force on the threaded sleeve 64, extending the service life of the adjustment mechanism.
[0019] The stirring mechanism 5 includes a drive motor 51 fixedly connected to the fertilizer storage tank 4, a transmission shaft 52 fixedly connected to the output end of the drive motor 51, multiple auxiliary stirring blades 53 and multiple main stirring blades 54 fixedly connected to the transmission shaft 52, with the auxiliary stirring blades 53 located inside the main stirring blades 54. The stirring mechanism 5 also includes a blade seat 55 fixedly connected to the bottom end of the transmission shaft 52, with the bottom end of each main stirring blade 54 connected to the blade seat 55. The main stirring blades 54 and auxiliary stirring blades 53 of the stirring mechanism 5 form a two-stage stirring process. When the main blades rotate, they drive the solution in the fertilizer storage tank 4 to circulate, preventing fertilizer from settling at the bottom of the tank. The auxiliary stirring blades 53, located inside the main blades, can disperse the local vortices and undissolved fertilizer particles formed when the main stirring blades 54 are used, ensuring complete fertilizer absorption. The system achieves complete dissolution, with the drive motor 51 providing a stable speed and significantly improving the uniformity of mixing compared to traditional single-paddle mixing. The paddle base 55 is fixed to the bottom of the drive shaft 52, connecting the bottoms of multiple main mixing paddles 54 into a single unit to form a stable mixing frame. This prevents the main paddles from bending and deforming due to excessive force during high-speed mixing. The fertilizer storage tank 4 has two lids 8 on its top, and a filter screen 14 is fixedly connected to the inner wall of the fertilizer storage tank 4. The filter screen 14 is located below the mixing mechanism 5. The two lids 8 facilitate the separate addition of fertilizer and water, preventing fertilizer from splashing during mixing and preventing solution from splashing out during mixing. The filter screen 14, located below the mixing mechanism 5, can filter out impurities or incompletely dissolved particles remaining after mixing, preventing clogging of the sprayer 7 nozzle and reducing the frequency of nozzle cleaning.
[0020] The working principle of this utility model is as follows: First, push the push rod 3 to move the device to the work point via the moving wheels 2. Check that the fertilizer storage tank 4 is undamaged and that the stirring mechanism 5 and the height adjustment mechanism 6 are stable and usable. Then, open the tank cover 8 of the fertilizer storage tank 4 and add a certain amount of soluble fertilizer and a certain amount of water. The amount of fertilizer added should be according to the fertilizer concentration. Close the tank cover 8 to ensure a good seal. After connecting the power supply to the equipment, start the drive motor 51 of the stirring mechanism 5 to make it rotate with the transmission shaft 52, the main stirring blade 54 and the auxiliary stirring blade 53. Then, the fertilizer solution can be stirred. After stirring, the fertilizer preparation is completed. Then, based on the height of the sweet orange plant, the servo motor 62 of the height adjustment mechanism 6 is activated, which will rotate the adjustment screw 63 and, under the action of the thread, slide the threaded sleeve 64 along the guide groove 66. Then, the mounting base 11 is raised and lowered through the transmission rod 65. At the same time, the guide slide plate 10 will rise and fall in the side rail 9. After adjusting to the appropriate height, the servo motor 62 is turned off. Next, the pump body 12 can be started. The fertilizer solution in the fertilizer storage tank 4 is filtered by the filter screen 14 and then pressurized by the pump body 12 and delivered to the sprayer 7 through the flexible infusion tube 13. The operator holds the push rod 3 and pushes the device to move along the row spacing of the sweet orange plants. The fertilizer solution is then evenly sprayed onto the branches, leaves and root areas of the plants through the sprayer 7.
