Description

Technical Field

[0001] This utility model relates to the field of plant protection spraying, specifically to an all-around plant protection spraying machine. Background Technology

[0002] Plant protection application is a key aspect of agricultural plant protection work. It aims to effectively control crop diseases, pests, weeds and other harmful organisms through the scientific and rational use of pesticides and other plant protection products, thereby ensuring the healthy growth of crops, improving crop yield and quality, and ensuring the stable and sustainable development of agricultural production.

[0003] The prior art disclosed in patent publication (announcement) number CN220054177U is an agricultural drone for spraying pesticides, including a clamping box. The clamping box contains a pesticide tank. The inner side wall of the clamping box is provided with a clamping structure, which includes a lower spring, an upper spring, a baffle, a limiting block, and a fixing plate. The upper and lower parts of the outer side of the clamping box are provided with grooves. The inner bottom wall of the groove is fixedly connected to the lower spring. One end of the lower spring is fixedly connected to the baffle.

[0004] The aforementioned patent document discloses a plant protection spraying drone, which solves the problems of traditional models having cumbersome disassembly of the pesticide tank for inconvenient pesticide filling and cleaning, as well as the problems of long propellers that are difficult to retract and take up a lot of space and are inconvenient to store. However, it has the following shortcomings:

[0005] The plant protection drones described in the aforementioned patent documents cannot adjust the spraying range. When facing large areas of farmland or farmland with complex terrain, it is difficult to achieve all-round and efficient spraying operations, which may result in blind spots in spraying and affect the effectiveness of pest and disease control.

[0006] Furthermore, the lack of a cushioning design for drone landing means that during landing, especially on uneven ground, the excessive impact can easily damage the overall structure of the drone and components such as the medicine tank, affecting the lifespan of the equipment and its subsequent use.

[0007] Therefore, we have made improvements to this and proposed an all-around plant protection spraying machine. Utility Model Content

[0009] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0010] All-around plant protection spraying machines are designed to solve the above problems.

[0011] The application is as follows:

[0012] The device includes a drone. A mounting plate is fixedly installed on the lower surface of the drone, and a medicine storage tank is fixedly installed on the lower surface of the mounting plate. A medicine inlet is fixedly installed on one side of the medicine storage tank. Two mounting brackets are fixedly installed on the lower surface of the mounting plate, and the two mounting brackets are located on both sides of the medicine storage tank. A medicine delivery pipe is installed on the surface of the mounting bracket, and a spraying mechanism is provided between the medicine delivery pipe and the medicine storage tank. Extension pipes are provided on both sides of the medicine delivery pipe, and a connecting mechanism is provided between the extension pipes and the medicine delivery pipe. Atomizing nozzles are fixedly installed on the lower surfaces of the medicine delivery pipes and the extension pipes, and a plug is connected to the other end of the extension pipes. Buffer mechanisms are provided on the lower surfaces of both sides of the bottom of the mounting bracket.

[0013] The spraying mechanism includes a medicine pump, which is fixedly installed on the lower surface of the medicine storage tank. A medicine extraction pipe and a connecting pipe are fixedly installed on both sides of the medicine pump, and the other end of the medicine extraction pipe is connected to the bottom of the medicine storage tank, and the other end of the connecting pipe is connected to the medicine delivery pipe.

[0014] As a preferred technical solution of this application, the connecting mechanism includes a rotating cylinder, and the rotating cylinder is rotatably connected to the outside of one end of the extension tube at both ends of the drug delivery tube. A threaded groove is opened on the outside of the other end of the extension tube, and the extension tube is threadedly connected to the rotating cylinder through the threaded groove on one end surface.

[0015] As a preferred technical solution of this application, a retaining ring is fixedly installed inside one end of the extension tube, and the retaining ring is engaged with the drug delivery tube. A sealing ring is fixedly connected to the surface of one end of the extension tube.

[0016] As a preferred technical solution of this application, the plug has the same structure as one end of the extension tube, and the plug is threadedly connected to the rotating cylinder.

[0017] As a preferred technical solution of this application, the buffer mechanism includes a fixed ring, which is fixedly installed on the outside of the fixed frame. A fixed rod is fixedly installed on the lower surface of the fixed ring, and a sliding rod is connected to the lower side of the fixed rod. A support block is fixedly installed on the lower end surface of the sliding rod.

[0018] As a preferred technical solution of this application, the fixed rod has a groove inside, and a stop block is slidably connected inside the groove. The upper end of the sliding rod is fixedly connected to the stop block, and a second spring is fixedly installed between the stop block and the inner wall of the groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. This all-around plant protection sprayer effectively solves the problem of difficult-to-adjust spraying range by setting up a connection mechanism between the extension tube and the delivery tube. The rotating cylinder and the extension tube are threaded together, with a retaining ring for locking and positioning, and a sealing ring to ensure airtightness. In actual operation, the extension tube can be flexibly installed or removed according to the farmland area and terrain, easily expanding or reducing the spraying range, reducing blind spots, and achieving all-around and efficient spraying operations, greatly improving the effect of pest and disease control and meeting the spraying needs of different farmlands.

[0022] 2. The buffer mechanism in this all-around plant protection sprayer provides reliable protection for the drone's landing. When the drone lands, the support block contacts the ground first, the sliding rod slides within the fixed rod, and the first and second springs are compressed. The spring force effectively buffers the impact force during landing, preventing damage to the overall structure of the drone and components such as the spray tank. This effectively extends the equipment's service life, ensuring the drone can still be used normally after multiple landings, reducing maintenance costs and operational risks.

[0038] Combination Figure 1 - Figure 7As shown, this utility model provides an all-around plant protection spraying machine, including a drone 1. A fixing plate 2 is fixedly installed on the lower surface of the drone 1, and a pesticide storage tank 3 is fixedly installed on the lower surface of the fixing plate 2. A pesticide inlet 4 is fixedly installed on one side of the pesticide storage tank 3. Two fixing brackets 5 are fixedly installed on the lower surface of the fixing plate 2, and the two fixing brackets 5 are arranged on both sides of the pesticide storage tank 3. A pesticide delivery pipe 6 is installed on the surface of the fixing bracket 5, and a spraying mechanism 7 is arranged between the pesticide delivery pipe 6 and the pesticide storage tank 3. Extension pipes 8 are arranged on both sides of the pesticide delivery pipe 6, and the extension pipes 8 are connected to the pesticide delivery pipe 6. A connecting mechanism 9 is provided between the pipes 6. An atomizing nozzle 10 is fixedly installed on the lower surface of the delivery pipe 6 and the extension pipe 8. A plug 12 is connected to the other end of the extension pipe 8. A buffer mechanism 11 is provided on the lower surface of both sides of the bottom of the fixing frame 5. The spraying mechanism 7 includes a medicine pump 701, which is fixedly installed on the lower surface of the medicine storage tank 3.

[0039] In this embodiment: the drone 1 serves as the main support, with a fixing plate 2 and a medicine storage tank 3 sequentially fixedly mounted on its lower surface. A medicine inlet 4 is located on one side of the medicine storage tank 3 for easy addition of medicine. Fixing frames 5 are symmetrically arranged on both sides of the medicine storage tank 3. A medicine delivery pipe 6 is mounted on the fixing frame 5. Through the medicine pump 701, extraction pipe 702, and connecting pipe 703 in the spraying mechanism 7, the medicine is transported from the medicine storage tank 3 to the medicine delivery pipe 6. Extension pipes 8 can be flexibly installed on both sides of the medicine delivery pipe 6, achieving a stable connection and convenient disassembly / reassembly with the connecting mechanism 9. Atomizing nozzles 10 on the lower surface of the medicine delivery pipe 6 and extension pipes 8 are responsible for spraying the medicine, and plugs 12 are used to seal the ends of the extension pipes 8. Simultaneously, a buffer mechanism 11 at the bottom of the fixing frame 5 provides cushioning protection for the drone 1 during landing, ensuring stable operation of the equipment.

[0040] In a preferred embodiment, the connecting mechanism 9 includes a rotating cylinder 901, which is rotatably connected to the outside of one end of the extension tube 8 at both ends of the drug delivery tube 6. A threaded groove is provided on the outside of the other end of the extension tube 8, and the extension tube 8 is threadedly connected to the rotating cylinder 901 through the threaded groove on one end surface.

[0041] In this embodiment, the rotating cylinder 901 is located outside both ends of the drug delivery tube 6 and forms a rotating connection with the outside of one end of the extension tube 8. The extension tube 8 can achieve a stable threaded connection with the rotating cylinder 901 through the threaded groove on one end surface, ensuring the tightness of the connection between the extension tube 8 and the drug delivery tube 6, preventing drug leakage, and facilitating quick disassembly and assembly of the extension tube 8 according to needs in actual use, and flexibly adjusting the drug application range.

[0042] In a preferred embodiment, a retaining ring 902 is fixedly installed inside one end of the extension tube 8, and the retaining ring 902 is engaged with the drug delivery tube 6. A sealing ring 903 is fixedly connected to the surface of one end of the extension tube 8.

[0043] In this embodiment, a retaining ring 902 fixedly installed inside one end of the extension tube 8 can engage with the drug delivery tube 6, which facilitates the installation of the extension tube 8 and improves the stability of the connection between it and the drug delivery tube 6. At the same time, a sealing ring 903 fixedly connected to one end of the extension tube 8 can form a tight seal at the connection, prevent drug leakage, and improve the overall drug application effect and equipment reliability.

[0044] In a preferred embodiment, the plug 12 has the same structure as one end of the extension tube 8, and the plug 12 is threadedly connected to the rotating cylinder 901.

[0045] In this embodiment, the plug 12 and one end of the extension tube 8 adopt the same structure, which facilitates maintenance and replacement during use.

[0046] In a preferred embodiment, the buffer mechanism 11 includes a fixing ring 1101, which is fixedly installed on the outside of the fixing frame 5. A fixing rod 1102 is fixedly installed on the lower surface of the fixing ring 1101, and a sliding rod 1103 is connected to the lower side of the fixing rod 1102. A support block 1104 is fixedly installed on the lower end surface of the sliding rod 1103. A first spring 1105 is sleeved on the outside of the sliding rod 1103, and the first spring 1105 is fixedly installed between the fixing rod 1102 and the support block 1104.

[0047] In this embodiment: the fixing ring 1101 is securely installed on the outside of the fixing frame 5, the fixing rod 1102 is installed on its lower surface and connected to the sliding rod 1103, and the support block 1104 at the lower end of the sliding rod 1103 is in direct contact with the ground; when the drone lands, the support block 1104 is first subjected to force, pushing the sliding rod 1103 to slide upward. At this time, the first spring 1105 sleeved on the outside of the sliding rod 1103 is compressed. The elastic deformation of the spring effectively absorbs and disperses the impact force during landing, avoiding damage to the overall structure of the drone and key components such as the medicine box, and greatly improving the service life and stability of the equipment.

[0048] In a preferred embodiment, the fixed rod 1102 has a groove 1106 inside, and a stop 1107 is slidably connected inside the groove 1106. The upper end of the sliding rod 1103 is fixedly connected to the stop 1107, and a second spring 1108 is fixedly installed between the stop 1107 and the inner wall of the groove 1106.

[0049] In this embodiment: when the drone lands, as the sliding rod 1103 slides upward under force, the stop 1107 fixed at its upper end moves upward synchronously along the slide groove 1106. The second spring 1108, fixedly installed between the stop 1107 and the inner wall of the slide groove 1106, begins to function, working in conjunction with the first spring 1105 to buffer the impact. This dual-spring design not only increases the buffering stroke and improves the buffering effect, but also distributes the impact force more evenly, effectively protecting the drone and the various components of the sprayer.

[0050] Specifically, the working principle of this solution is as follows:

[0051] During operation, the liquid medicine is added to the storage tank 3 through the inlet 4. The medicine pump 701 draws the liquid medicine from the bottom of the storage tank 3 through the extraction pipe 702, and then delivers it to the delivery pipe 6 through the connecting pipe 703. Extension pipes 8 can be installed on both sides of the delivery pipe 6 as needed. The rotating cylinder 901 is rotatably connected to the delivery pipe 6 and the extension pipes 8. The extension pipes 8 are threadedly connected to the rotating cylinder 901 through threaded grooves. The retaining ring 902 engages with the delivery pipe 6, and the sealing ring 903 ensures a seal at the connection to prevent liquid medicine leakage. The liquid medicine is sprayed out through the atomizing nozzles 10 on the lower surface of the delivery pipe 6 and the extension pipes 8.

[0052] When the drone 1 lands, the buffer mechanism 11 comes into play. The support block 1104 contacts the ground first, pushing the sliding rod 1103 upward, compressing the first spring 1105 and absorbing part of the impact force. At the same time, the stop block 1107 at the upper end of the sliding rod 1103 moves upward along the slide groove 1106, and the second spring 1108 also begins to deform, working in conjunction with the first spring 1105 to buffer the impact, increasing the buffer stroke, evenly dispersing the impact force, avoiding damage to the overall structure of the drone 1 and key components such as the medicine tank, ensuring stable operation of the equipment, and improving its service life and application effect.

[0053] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0054] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
