Technical Field
[0001] This utility model relates to the field of watermelon planting technology, specifically to a spraying device for watermelon planting with adjustable spraying range. Background Technology
[0002] Watermelon, a cucurbitaceous plant native to Africa, is known for its large, juicy fruit. The flesh is typically red or yellow, rich in water, vitamin C, lycopene, and minerals, making it an important summer fruit for cooling off. Its rind is smooth, often with dark stripes, and the seeds are black or white, edible or used for oil extraction. Watermelon cultivation requires loose soil and precise water and fertilizer management, combining nutritional and economic value. Currently, "trellised vertical cultivation technology" has become a new trend in watermelon planting. This technology guides the watermelon vines upwards along supports, improving space utilization and air circulation between plants, creating an excellent environment for watermelon growth.
[0003] Spraying pesticides is an important part of watermelon cultivation to prevent and control pests and diseases and ensure the healthy growth of watermelons. However, most existing watermelon spraying devices have inconvenient nozzle height and angle adjustment, making it difficult to adapt to watermelon plants of different heights. Therefore, improvements are urgently needed. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] Example 1:
[0021] like Figures 1-5 As shown, a watermelon spraying device with adjustable spraying range includes a pesticide storage tank 1 and a protective plate 2. The pesticide storage tank 1 is equipped with four casters 26 for easy movement of the entire device. A push rod 27 is fixedly mounted on the pesticide storage tank 1 for easy pushing of the entire device by the user. The protective plate 2 is fixedly mounted on the pesticide storage tank 1 to protect the pesticide delivery pump 8. It also includes:
[0022] like Figure 2 , 3As shown in Figure 5, a drug supply mechanism is installed on the drug storage tank 1 and the protective plate 2. The drug supply mechanism includes: a drug delivery pump 8, fixedly installed on the drug storage tank 1; a connecting pipe 9, installed on the drug delivery pump 8, one end of which is fixedly connected to the drug delivery pump 8 for the drug delivery pump 8 to draw the drug solution from the drug storage tank 1; an infusion pipe 10, installed on the drug delivery pump 8, one end of which is fixedly connected to the drug delivery pump 8 and the infusion pipe 10 is fixedly connected to the protective plate 2; a sliding plate 11, fixedly installed at the end of the infusion pipe 10 away from the drug delivery pump 8; and a piston 12, fixedly installed on the sliding plate 11. When in operation, the drug delivery pump 8 is started. The drug delivery pump 8 draws the medicine liquid in the medicine storage tank 1 through the connecting pipe 9 and delivers the medicine liquid to the lifting rod 13 through the infusion pipe 10. The sliding plate 11 is used to slide inside the lifting rod 13, and the piston 12 is used to prevent the medicine liquid from flowing out from the gap between the infusion pipe 10 and the lifting rod 13, so that the lifting rod 13 can be moved without affecting the flow of medicine liquid.
[0023] like Figure 3 , 5 As shown, a lifting mechanism is mounted on the drug supply mechanism and is coaxially aligned with the drug supply mechanism. The lifting mechanism includes: a lifting rod 13, which is fixedly mounted on the liquid distribution plate 4 and slidably connected to the infusion tube 10; and two limiting grooves 14, which are symmetrically arranged on the lifting rod 13 to limit the lifting position of the sliding plate 11. Two hydraulic rods 3 are symmetrically and fixedly connected to the protective plate 2. A dispensing plate 4 is located at the end of the lifting mechanism away from the protective plate 2 and is fixedly connected to the hydraulic rods 3. During operation, activating the hydraulic rods 3 causes the hydraulic cylinder to move the dispensing plate 4 up and down, which in turn moves the lifting rod 13 up and down. The lifting rod 13 ensures that the liquid is transferred to the moving dispensing plate 4. The limiting groove 14 restricts the movement of the sliding plate 11 and the piston 12. The dispensing plate 4 also drives the positioning plate 5, the rotating mechanism, the rotation mechanism, the limiting key 6, and the pull rope 7 to move up and down. This allows for adjustment of the nozzle height to accommodate watermelon plants of different heights.
[0024] like Figure 1 , 2As shown in Figures 4 and 5, a rotating mechanism is located at the center of the separating plate 4. The rotating mechanism includes: two fixed plates 15, symmetrically arranged on the separating plate 4 and fixedly connected to it; a rotating motor 16, fixedly mounted on the fixed plate 15; a first rotating rod 17, rotatably mounted on the fixed plate 15, one end of which is fixedly connected to the output end of the rotating motor 16; a first gear 18, fixedly mounted on the first rotating rod 17; a second rotating rod 19, rotatably mounted on the fixed plate 15; a second gear 20, fixedly mounted on the second rotating rod 19, meshing with the first gear 18; and two pull ropes 7, one end of which is fixedly mounted on the first rotating rod 17, and the other end of which is fixedly mounted on the second rotating rod 19. During operation, the rotary motor 16 is started, which drives the first rotating rod 17 to rotate. The first rotating rod 17 pulls the fixed key 24 around the rotating rod 21 via the pull rope 7. The first rotating rod 17 also drives the first gear 18 to rotate, which in turn drives the second gear 20 to rotate. The second gear 20 then drives the second rotating rod 19 to rotate, which in turn pulls the fixed key 24 around the rotating rod 21 via the pull rope 7, thereby driving the rotating mechanism to rotate.
[0025] There are four positioning plates 5, which are fixedly connected to the liquid separating plate 4.
[0026] like Figure 1 , 2As shown in Figure 4, there are two rotating mechanisms, symmetrically arranged at the ends of the dispensing plate 4. Each rotating mechanism includes: four rotating rods 21 rotatably mounted on the positioning plate 5; two infusion plates 22 fixedly mounted on the rotating rods 21; multiple atomizing nozzles 23 fixedly mounted on the infusion plates 22; two fixing keys 24 fixedly mounted on the infusion plates 22 and connected to both the infusion plates 22 and the other ends of the two pull ropes 7; and a rotatable connecting tube 25 mounted on both the infusion plates 22 and the dispensing plate 4, with one end fixedly connected to the dispensing plate 4 and the other end fixedly connected to the infusion plate 22. During operation, the first rotating rod 17 and the second rotating rod 19 drive the fixed key 24 to rotate around the rotating rod 21 via the pull rope 7. The fixed key 24 drives the infusion plate 22 to rotate, and the infusion plate 22 drives the atomizing nozzle 23 to rotate. At the same time, when the pull rope 7 does not apply tension to the fixed key 24, the rotating mechanism rotates under the action of gravity, thereby adjusting the angle of the nozzle. The rotating rod 21 is used to limit the position of one end of the infusion plate 22, and the rotatable connecting tube 25 is used to transport the medicine in the dispensing plate 4 to the infusion plate 22.
[0027] Two limit keys 6 are provided, and the two limit keys 6 are symmetrically fixedly connected to the liquid separating plate 4; they are used to limit the position of the pull rope 7, so as to keep the pull rope 7 in a taut state.
[0028] The working process and usage of this utility model's watermelon planting spraying device with adjustable spraying range are as follows: The push rod 27 is manually pushed, and the device is moved to the target area using the casters 26. The hydraulic rod 3 is activated, causing the dispensing plate 4 to move up and down. The dispensing plate 4 then causes the lifting rod 13 to move up and down, thereby allowing the piston 12 and sliding plate 11 to move within the limiting groove 14. This ensures that the supply mechanism can deliver the pesticide solution to the dispensing plate 4 while the lifting rod 13 moves up and down. The dispensing plate 4 then causes the positioning plate 5 to move up and down, which in turn causes the delivery plate 22 to move up and down. The delivery plate 22 then causes the atomizing nozzle 23 to move up and down, thus adjusting the height of the atomizing nozzle 23. The rotary motor 16 is then activated. 16 drives the first rotating rod 17 to rotate, the first rotating rod 17 drives the first gear 18 to rotate, the first gear 18 drives the second gear 20 to rotate, the second gear 20 drives the second rotating rod 19 to rotate, the first rotating rod 17 and the second rotating rod 19 pull the fixing key 24 around the rotating rod 21 through the pull rope 7, the fixing key 24 drives the infusion plate 22 to rotate, the infusion plate 22 drives the atomizing nozzle 23 to rotate, thereby adjusting the direction of the atomizing nozzle 23; the medicine pump 8 is started, the medicine pump 8 draws the medicine liquid in the medicine storage tank 1 through the connecting pipe 9, and delivers the medicine liquid to the lifting rod 13 through the infusion pipe 10, so that the medicine liquid is transported to the atomizing nozzle 23 in sequence through the dispensing plate 4, the rotatable connecting pipe 25 and the infusion plate 22, so as to achieve spraying.
