Description

Technical Field

[0001] This utility model relates to the field of plant irrigation equipment technology, and in particular to a retractable spraying device. Background Technology

[0002] With the continuous advancement of agricultural modernization, higher demands are being placed on the performance and efficiency of agricultural sprinkler equipment. As a crucial piece of equipment in agricultural production, the improvement and innovation of sprinkler equipment are of great significance for enhancing irrigation efficiency, conserving water resources, and reducing production costs. However, current agricultural sprinkler equipment on the market still faces numerous problems in practical applications, which urgently need to be addressed.

[0003] Currently, agricultural sprinkler equipment on the market is being improved in two main ways: optimized nozzle design and precision control systems. Optimized nozzle design results in more uniform water distribution and wider coverage, lower costs, and easier replacement, but its application is limited, mainly to fixed locations, and large-scale replacement is required after the water pipes age. Precision control systems offer significant advantages in water conservation, efficient agricultural production, and automated management, especially in large-scale agriculture, where they can improve irrigation efficiency and reduce resource waste. However, these systems also have disadvantages such as high initial investment, high maintenance costs, and strong dependence on technology, which may pose a significant economic burden, particularly for small-scale farmers or those with limited funds.

[0004] Currently, the design and improvement of sprinkler equipment on the market still have significant shortcomings, and there is no comprehensive and convenient improvement solution yet. This results in deficiencies in the performance, efficiency, and ease of operation of existing devices, making it difficult to meet diverse needs. Therefore, the market demand for sprinkler equipment remains relatively large, especially in the areas of intelligence, water conservation, high efficiency, and ease of operation, where the market urgently needs more innovative and practical solutions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a retractable spraying device that takes into account water spraying performance, efficiency, water saving and ease of use.

[0006] To solve the above-mentioned technical problems, this utility model provides a retractable spraying device, including a lifting base, on which a spraying module is fixedly connected. The spraying module includes a spraying platform fixedly installed on the top of the lifting base, a motor at the bottom of the spraying platform, and spraying blades rotatably connected to both sides of the spraying platform. The motor is fixedly connected to the spraying blades. The spraying blades include several extension arms that are hinged sequentially. A second telescopic push rod is provided between two adjacent extension arms, and the two ends of the second telescopic push rod are respectively hinged to the two extension arms. A spraying pipe is fixedly connected to the bottom of the extension arms. Several spraying nozzles are provided at the bottom of the spraying pipe. A pipe interface is provided at the end of the spraying pipe, and the pipe interface is connected to a water pump, a water source, or interconnected with them.

[0007] The water spraying module is raised or lowered via a lifting base, and the multi-stage articulated extension arm of the spray blades is extended or retracted via a second telescopic push rod. This allows for free and precise adjustment of the spraying range according to the actual needs of the farmland, saving water and pesticides. When raised or extended, it covers a large area; when lowered or retracted, it reduces the footprint, solving the problems of fixed nozzle positions and limited application range of traditional sprinklers. It is especially suitable for precision irrigation of small to medium-sized or irregularly shaped fields. The simple and compact structure accommodates both fixed and mobile applications, making it widely applicable. Furthermore, in case of partial damage, only a single section of the extension arm or sprinkler head needs to be replaced, eliminating the need for complete overhaul and reducing maintenance costs.

[0014] Figure 7 This is a schematic diagram of a retractable spraying device according to the second embodiment of this utility model. Detailed Implementation

[0015] The utility model will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] All electrical components mentioned in this manual are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer that provides control.

[0017] Figures 1 to 6 This is the first embodiment of the present utility model. For example... Figure 1 As shown, the retractable agricultural spraying equipment includes a lifting base 1, on which a water spraying module 2 is fixedly connected.

[0018] The lifting base 1 includes a lower platform 11 and an upper platform 12 arranged in parallel. The lower platform 11 and the upper platform 12 are connected by several connecting rods 13 that are hinged to each other in a scissor-like structure. The scissor-like structure also includes a first telescopic push rod 14. Specifically, both sides of the lower platform 11 and the upper platform 12 are provided with vertical sides 15 perpendicular to the platform plane. The vertical sides 15 are provided with slide rails 16. The connecting rods 13 are fixedly connected to sliding pins 17 coupled within the slide rails 16. Rollers 18 are sleeved on the sliding pins 17. The rollers 18 reduce the friction between the sliding pins 17 and the slide rails 16 when the lifting base 1 is raised or lowered, making the lifting action smoother and extending the service life of the equipment.

[0019] The water spraying module 2 includes a water spraying platform 21 fixedly mounted on the top of the lifting base 1. A motor 22 is provided at the bottom of the water spraying platform 21. Water spraying blades are rotatably connected to both sides of the water spraying platform 21. The motor 22 is fixedly connected to the water spraying blades. The water spraying blades include several extension arms 24 that are hinged in sequence. A second telescopic push rod 25 is provided between two adjacent extension arms 24. The two ends of the second telescopic push rod 25 are respectively hinged to the two extension arms 24. A water spraying pipe 26 is fixedly connected to the bottom of the extension arm 24. Several water spraying nozzles 27 are provided at the bottom of the water spraying pipe 26. A pipe interface 23 is provided at the end of the water spraying pipe 26. The pipe interface 23 is connected to an external water pump, a water source (not shown in the figure), or interconnected.

[0020] An electrical box 3 is fixedly installed on the lower platform 11, such as Figure 2As shown, the electrical box 3 includes a box body 31 with a transparent cover on top. The interior of the box body 31 is divided into a battery space, a circuit board space, and a humidity detection space by a partition 32, where a battery 33, a circuit board 34, and a humidity detector 35 are respectively installed. The circuit board 34 is equipped with a photoresistor. A humidity hole 36 is provided on the side wall of the box body 31. The humidity detection space is connected to the outside of the box body 31 through the humidity hole 36, allowing the humidity detector 35 to test the external humidity. The partition 32 also prevents the battery 33 and circuit board 34 from short-circuiting due to moisture. The battery 33 and circuit board 34 are electrically connected to the motor 22, the first telescopic push rod 14, the second telescopic push rod 25, and other electrical components.

[0021] like Figure 3 As shown, in this embodiment, the sprinkler platform 21 adopts a lightweight hollowed-out window design to reduce its weight, facilitate installation on different vehicle models, and enhance the overall flexibility of the equipment. Grooves 29, at the same height as the sprinkler blades, are provided on both sides to facilitate the retraction of the sprinkler blades, thus expanding the controllable range of the sprinkler blade extension and retraction and reducing the overall footprint of the sprinkler equipment when not in use.

[0022] The sprinkler platform 21 has a mounting slot 211 on its top, and a mounting cover 212 on top of the mounting slot 211. A signal booster transceiver 213 with an antenna is installed inside the mounting slot 211, and the antenna protrudes from an antenna hole in the mounting cover. The signal booster transceiver 213 ensures signal transmission and reception of the equipment in inclement weather and remote locations.

[0023] In use, the signal amplification transceiver 213 receives control signals from the base station remote controller. The first telescopic push rod 14 drives the scissor structure to lift the upper platform 12. Simultaneously, the sprinkler blades, under the combined action of the motor 22 and the second telescopic push rod 25, unfold multi-stage extension walls from both sides of the sprinkler platform 21, precisely controlling the height and coverage width of the sprinkler heads 27 to achieve precise watering and pesticide application, thus saving water (pesticide) and ensuring accurate water (pesticide) delivery. Throughout the process, the battery 33 in the electrical box 3 continuously supplies power, the humidity detector 35 monitors environmental data in real time, the photoresistor tests the external light environment or adjusts the circuit on / off according to the light intensity, the signal amplification transceiver 213 amplifies and processes the environmental data through the antenna and transmits it in real time to the remote controller via satellite. While the base station program automatically adjusts according to the data, the staff can also finely adjust the watering operation and water usage, ultimately achieving intelligent and customized irrigation spraying operations under different temperature and light environments.

[0024] The telescopic spraying agricultural equipment can be fixed to the work vehicle in various ways, including but not limited to: welding; modular interfaces on the work vehicle for connecting the equipment to the work vehicle frame via prefabricated quick-disassembly interfaces; or the lower platform 11 of the equipment can be removed, and the electrical box 3 and the connecting rod 13 of the scissor lift structure can be directly installed on the work vehicle with the slide rail 16. Here, this embodiment proposes a magnetic fixing structure.

[0025] like Figure 4 As shown, a mounting magnet 4 is fixedly connected to the bottom of the lower platform 11. The mounting magnet 4 is an electromagnet, powered by a battery 33, and uses magnetic force to attract the metal chassis or pre-embedded metal plate of the work vehicle, achieving quick assembly and disassembly and stable fixation. In addition, various magnetic accessories can be added using the electromagnet.

[0026] like Figure 5 The magnetic accessory fixing clamp 5 shown includes a clamp body 51. Two sets of opposing spring clips 52 are provided on the outer side of the clamp body 51. A clamp magnet 53, which is an electromagnet, is located at the center of the clamp body 51 and is powered by a clamp battery 54. In use, the fixing clamp 5 is clamped and installed in the desired position using the opposing spring clips 52, and the mounting magnet 4 is attracted to the clamp magnet 53.

[0027] like Figure 6 Another magnetic attachment, the landing gear 6, includes a curved mesh support 61. A landing gear magnet 62 and a landing gear battery 63 are located at the center of the mesh support 61. The landing gear magnet 62 is an electromagnet, powered by the landing gear battery 63. In use, the mesh support 61 is bound to the desired installation location, and the mounting magnet 4 is attached to the landing gear magnet 62. This binding method allows for flexible adaptation to uneven terrain and complex environments where the fixing clamp 5 is not suitable, expanding the application range of the spraying equipment.

[0028] Figure 7 This is the second embodiment of the present invention. The second embodiment is largely the same as the first embodiment, except that the sprinkler platform 21 has a box-shaped structure with a water tank inside. The sprinkler platform 21 has a water inlet 71 at the top and a water outlet 72 on its side wall. A water pump is installed inside the water tank, and the water outlet 72 is connected to a pipe interface 23 via a flexible hose (not shown). This embodiment integrates the water tank and the sprinkler equipment, eliminating the need for additional water tanks and pumps, making it easier to adapt to different vehicle models. Furthermore, this design shortens the connection distance between the water source and the sprinkler head 27, avoiding the problems of tangled or dragged connecting pipes in complex environments. In specific implementation, considering the increased weight of the upper part of the equipment after the water tank is filled, several first telescopic push rods 14 can be added within the scissor structure to ensure overall stability.

[0029] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
