Description

Technical Field

[0001] This utility model relates to the field of agricultural spraying technology, specifically to a rotary spraying device for lychee cultivation. Background Technology

[0002] In the refined management of litchi cultivation, foliar fertilization and pest and disease control are crucial. Currently, growers generally use backpack sprayers or fixed pipeline spraying equipment. Backpack sprayers suffer from problems such as small liquid storage capacity, high labor intensity, and narrow spray coverage, resulting in low work efficiency and difficulty in effectively spraying tall tree canopies. Traditional fixed or cart-type spraying equipment often has fixed spray booms or can only be manually swung, creating spray dead zones and failing to achieve uniform, circumferential spraying, especially on the inner branches and undersides of leaves of litchi trees, resulting in poor coverage and affecting the utilization rate of pesticides and fertilizers.

[0003] Furthermore, most existing spraying equipment lacks an effective mixing mechanism in its liquid tank, or only uses a simple single-shaft mixer. When spraying pesticides, foliar fertilizers, and other materials that require mixing, especially suspension concentrates and wettable powders, sedimentation and stratification are easily produced, resulting in low concentrations in the early stages of spraying and high concentrations in the later stages. This not only affects the control effect but may also cause phytotoxicity due to excessively high local concentrations. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a rotary spraying device for lychee planting, so as to solve the problems of uneven spraying, insufficient mixing and inconvenient operation in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A rotary spraying device for lychee cultivation, comprising:

[0007] trolley;

[0008] The storage tank, the pump, and the handheld rotary spraying mechanism are all mounted on the chassis of the trolley. The inlet of the pump is connected to the bottom of the storage tank through a conveying pipe, and the outlet is connected to the handheld rotary spraying mechanism through a conveying hose. The top of the storage tank is equipped with a filling port with a cap.

[0009] A stirring mechanism is used to stir the mixture in the storage tank.

[0010] As an improvement, the storage tank is a cylindrical structure with a drain outlet equipped with a valve on the bottom side. The inside of the storage tank needs to be cleaned regularly, and the wastewater after cleaning is discharged through the drain outlet.

[0011] As an improvement, the stirring mechanism includes a stirring drive mechanism, a stirring shaft, and stirring blades; multiple stirring blades are evenly fixed on the stirring shaft, and the stirring shaft and stirring blades are evenly arranged circumferentially within the storage tank. The stirring drive mechanism drives the blades to synchronously rotate and revolve around the storage tank, thus effectively stirring the mixture within the storage tank.

[0012] As an improvement, the stirring drive mechanism includes a stirring motor, a rotating shaft, a disc, a gear ring, and a movable gear; the rotating shaft is fixed on the top surface of the disc, passes through and is rotatably connected to the top wall of the storage tank, and its top end is driven by the stirring motor installed and fixed on the top of the storage tank. The top ends of each stirring shaft pass through and are rotatably connected to the disc, and the movable gear is fixed to the top of the stirring shaft. The gear ring is mounted and fixed to the top of the storage tank through multiple support rods, and meshes with each movable gear. The movable gear is located inside the gear ring.

[0013] As an improvement, the stirring blades on each of the stirring shafts avoid each other, and their stirring ranges partially overlap. This further enhances the stirring effect.

[0014] As an improvement, the handheld rotary spraying mechanism includes a handheld tube, an adapter tube, a star-shaped tube, nozzles, and a rotary drive mechanism. One end of the handheld tube is connected to a water / material delivery hose, and the other end is closed, with the portion near the closed end forming a square tube section. An adapter tube is rotatably connected to the side of the square tube section, and the connection is rotary-sealed. The other end of the adapter tube is fixed to a star-shaped tube, and multiple nozzles are evenly installed on the side of the star-shaped tube facing away from the adapter tube. The adapter tube is driven by a rotary drive mechanism located on the square tube section, which rotates it at a low speed. This allows for a wider spraying range.

[0015] As an improvement, the rotary drive mechanism includes a rotary drive motor mounted and fixed to the free end of the handheld tube, and the output shaft of the rotary drive motor is connected to the adapter tube via a belt and pulley structure.

[0016] It is worth mentioning that the material pump, stirring motor and rotary drive motor in this technical solution are all existing devices in common knowledge, and their use and control methods are all existing technologies.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. This novel device, through its specially designed stirring mechanism, can simultaneously drive multiple stirring shafts to rotate on their own axis and revolve around the center of the storage tank, forming a complex composite motion trajectory. This motion method can powerfully agitate all areas within the storage tank, especially the traditionally unmixed areas such as the center and bottom edges, ensuring that mixtures of different densities (such as pesticides and fertilizers) remain in a uniform suspension state. This fundamentally solves the problem of uneven spray concentration caused by sedimentation or stratification, guaranteeing the stability and safety of the operational effect.

[0019] 2. This novel handheld rotary spraying mechanism innovatively adopts a cross-shaped tube driven by a motor and a multi-nozzle design that allows for low-speed rotation. During operation, the nozzles rotate along with the cross-shaped tube, transforming the originally fixed linear or fan-shaped spray surface into a dynamic three-dimensional spray field. This allows the sprayed droplets to cover the top of the lychee tree canopy, its inner and outer canopies, and the front and back of the leaves, greatly reducing spray dead zones and significantly improving the uniformity and adhesion of pesticides or fertilizers.

[0020] 3. This new type of sprayer is integrated into a trolley, making it easy to move and reducing the burden on operators. While the handheld component offers enhanced functionality, its rational structural design maintains a comfortable operating feel. Operators only need to hold the sprayer and control its direction to achieve efficient, all-around spraying, eliminating the need for frequent arm swings and reducing labor intensity. The storage tank capacity is significantly larger than that of backpack sprayers, allowing for larger area coverage with a single fill, effectively improving the overall efficiency of orchard management.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] A rotary spraying device for lychee cultivation mainly consists of three modules: a mobile support section, a mixing section, and a spraying section.

[0031] Mobile load-bearing component: mainly composed of trolley 1, whose chassis is used to integrate and install other components. The wheels are preferably agricultural tires with a certain width and tread pattern to adapt to the rugged ground of the orchard and ensure the stability and convenience of movement.

[0032] The mixing section includes a storage tank 2, a pump 3, and a mixing mechanism. The storage tank 2 is preferably made of corrosion-resistant polyethylene and has a cylindrical structure with a filling port 5 with a sealing cap at the top for adding solid or liquid agricultural materials. A drain port 6 with a ball valve is located on the bottom side of the storage tank 2 to facilitate thorough cleaning and drainage of wastewater and sediment after operation.

[0033] The stirring mechanism is the core component ensuring effective mixing. Its specific structure is as follows: A disc 11 is connected to the center of the top wall of the storage tank 2 via a rotating shaft 10 fixed to its top surface. The top of the rotating shaft 10 is directly connected to the output shaft of the stirring motor 9, which is fixedly mounted on the top of the storage tank 2, via a coupling. Three stirring shafts 7 (three are shown in the diagram, but the actual number can be adjusted) are evenly distributed and rotatably connected along the circumference of the disc 11. A movable gear 13 is fixedly mounted on the upper part of each stirring shaft 7. A fixed gear ring 12 is suspended and fixedly mounted on the inner top of the storage tank 2 via several support rods 14, acting like a "bridge". All movable gears 13 mesh with this fixed gear ring 12 and are located inside the gear ring 12.

[0034] When the stirring motor 9 starts, it drives the rotating shaft 10 to rotate the disc 11, which in turn drives the three stirring shafts 7 to revolve around the central axis of the storage tank 2. Simultaneously, because the movable gear 13 at the top of the stirring shaft 7 meshes with the fixed gear ring 12, during the revolution, the movable gear 13 is forced to roll along the gear ring 12, thereby driving each stirring shaft 7 to rotate on its own axis. This combined revolution and rotation motion drives the multiple stirring blades 8 fixed on the stirring shafts 7 to form a strong and dead-zone-free vortex and shear flow within the storage tank 2, resulting in a stirring effect far exceeding that of single-dimensional stirring. To optimize the flow field, the stirring blades 8 on each stirring shaft 7 are staggered in their trajectories, but their stirring ranges are designed to partially overlap, ensuring that the entire cross-section of the tank is effectively covered.

[0035] The spraying section includes a handheld rotary spraying mechanism and connecting pipelines. The material pump 3 is mounted on the chassis of the trolley 1, and its inlet is connected to the bottom of the storage tank 2 through a pipeline. Its outlet is connected to the handheld rotary spraying mechanism through a long material delivery hose 4.

[0036] The specific structure of the handheld rotary spraying mechanism is as follows: One end of the handheld tube 15 is connected to the material delivery hose 4, and the other end is a closed end. A section near the closed end is constructed as a square tube section 19. An adapter tube 16 is rotatably connected to the side wall of the square tube section 19 via a bearing (not shown in the figure), and a rotary sealing ring (not shown in the figure) is provided at the connection to ensure a seal. The other end of the adapter tube 16 is fixedly connected to a star-shaped tube 17 (i.e., a tube with multiple radial branches). Atomizing nozzles 18 are installed at the end of each branch of the star-shaped tube 17 and on the tube wall facing the working direction.

[0037] To drive its rotation, a rotary drive motor 20 is installed at the free end of the handheld tube 15 (typically near the operator's hand). This motor is preferably a low-speed micro motor. A small pulley is mounted on the motor's output shaft, and a large pulley is mounted at a corresponding position on the adapter tube 16. The two are connected by a synchronous belt or belt (not shown in the figure) to form a belt-pulley drive structure. By selecting an appropriate transmission ratio, the adapter tube 16 and the entire cross-shaped tube 18 assembly at its front end can rotate smoothly at a low speed (e.g., tens of revolutions per minute).

[0038] Work process:

[0039] Before operation, the operator moves the cart 1 to the work area and adds clean water and the pesticide or foliar fertilizer to be sprayed into the storage tank 2 through the filling port 5. The mixing motor 9 is started, and the mixing mechanism begins to work, thoroughly mixing the materials. During this time, the spraying device can be moved next to the lychee tree to be sprayed by holding the hand hose 15.

[0040] When preparing to spray, start the pump 3 and the rotary drive motor 20. The pump 3 pumps the well-mixed pesticide solution from the storage tank 2, delivers it through the delivery hose 4 to the handheld hose 15, then through the adapter hose 16 into the star-shaped hose 17, and finally sprays it out from all the nozzles 18. At the same time, the rotary drive motor 20 drives the adapter hose 16 and the star-shaped hose 17 to slowly rotate all the nozzles 18 together via a belt and pulley structure, thereby achieving 360° all-around dynamic spraying. The operator only needs to move and adjust the spray angle according to the shape of the tree canopy to easily complete the efficient and uniform spraying operation.

[0041] After the operation is completed, turn off all power. The residual liquid in the storage tank can be drained through drain port 6 and the tank can be cleaned for easy subsequent use and maintenance.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
