Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, and in particular to an improved variable diameter spraying device for visual and quantitative application of selenium-enriched foliar fertilizer for plants. Background Technology

[0002] Selenium is a beneficial element that plays a crucial role in plant growth. On the one hand, it accelerates seed germination and stimulates plant development; on the other hand, it enhances root vitality, aiding in nutrient uptake and metabolism. Selenium also strengthens the plant's antioxidant capacity by increasing photosynthesis and chlorophyll content, further enhancing the crop's resistance to environmental stress. In cultivation, there are generally two methods of applying selenium fertilizer to plants: root application and foliar application. Foliar fertilization, which involves supplementing nutrients to the plant through the leaves, has become very common in crop cultivation in recent years, and it is another effective way for crops to absorb nutrients.

[0003] Existing technologies also disclose spraying devices, such as the patent application number CN202323175905.6, which discloses a selenium-enriched vegetable spraying device, including a trolley. A spraying device is provided on the upper surface of the trolley at one end. The spraying device includes a bracket, the lower end of which is fixedly connected to the trolley. A bearing is provided on the upper surface of the bracket at the middle position. A rotating shaft is provided inside the bearing. A spray box is fixedly provided on the upper surface of the rotating shaft. An atomizing nozzle is provided on the outer wall of the spray box. The lower end of the rotating shaft passes through the bracket and is provided with a gear. A rack is provided on one side of the gear, and the rack is meshed with the gear. A hydraulic rod is provided on one side of the bracket. The output end of the hydraulic rod is fixedly connected to the rack. A guide rod is provided at the other end of the rack. A guide hole is correspondingly opened on the outer wall of the bracket. The guide rod slides in cooperation with the guide hole. A storage device is provided on the upper surface of the trolley. The storage device includes a comprehensive box. The comprehensive box has a water storage chamber and a mixing chamber inside. The disclosed spraying device uses a hydraulic rod, with its output end fixedly connected to a rack and pinion. This allows the hydraulic rod to drive the gears, rotating shaft, and spray box to rotate, thereby changing the spraying area of ​​the atomizing nozzle. This adjustment method is suitable for spraying selenium-enriched fertilizer onto crops with different planting areas, improving efficiency. While the disclosed spraying device undeniably achieves the aforementioned technical effects, it also has certain shortcomings. For example, increasing the spraying area by rotating the atomizing nozzle cannot guarantee uniform spraying density, and the fertilizer box is not visible, making it difficult to control the selenium concentration and affecting the foliar application effect of selenium on crops.

The drive gear 42 and the driven gear 44 mesh, and the driven gear 44 meshes with a tooth groove 51. One end of the first rotating rod 41 extends through to the outside of the water tank 3 and is fixedly mounted with a rocker handle 48. The two sleeves 45 are respectively fixedly mounted on… On both sides of the water tank 3, the two ends of the second rotating rod 43 pass through the two side walls of the second equipment cavity 31 and extend into the sleeve 45 on the same side, and are rotatably connected to the sleeve 45. The top of the sleeve 45 is provided with a screw hole 451, and a stud 46 is threaded into the screw hole 451. A first knob 47 is fixedly installed on the top of the stud 46. Rubber sleeves 431 are fixedly installed on both sides of the outer surface of the second rotating rod 43 inside the sleeve 45. The inner end of the stud 46 abuts against the outer surface of the rubber sleeve 431 to restrict the second rotating rod 43 and prevent the second rotating rod 43 from rotating.

[0036] In use, when it is necessary to raise the lifting tube 5, turn the rocker handle 48. The rocker handle 48 drives the first rotating rod 41 to rotate. The first rotating rod 41 drives the drive gear 42 to rotate. The drive gear 42 drives the driven gear 44 to rotate. The driven gear 44 drives the lifting tube 5 to move upward. When the lifting tube 5 moves to the specified height, turn the first knob 47. The first knob 47 drives the inner end of the stud 46 to press against the rubber sleeve 431, thereby restricting the rotation of the second rotating rod 43, and further restricting the rotation of the driven gear 44. The driven gear 44 restricts the movement of the lifting tube 5, thereby fixing the lifting tube 5 at the specified height.

[0037] The variable diameter spray device 8 includes a support plate 81, a movable plate 82, and a control plate 83. The support plate 81 is fixedly installed on the top of the bracket 7. The rear end of the movable plate 82 has a sliding groove 821, and the front part of the support plate 81 slides in the sliding groove 821. Adjusting rods 84 are rotatably installed on the front and rear sides of the left and right sides of the control plate 83. The four adjusting rods 84 are paired up and rotatably connected to the two sides of the lower support plate 81. The front of the left and right sides of the control plate 83 is rotatably connected to linkage rods 85. The two linkage rods 85 are rotatably connected to the rear sides of the left and right ends of the movable plate 82. Multiple atomizing nozzles 87 are fixedly installed from front to back on the bottom of the movable plate 82. The water supply pipe 10 is connected to the multiple atomizing nozzles 87. A control handle 86 is fixedly installed on the top of the control plate 83.

[0038] When it is necessary to adjust the spray range of the atomizing nozzle 87, the user grasps the control handle 86 and pushes the control handle 86 forward. The control handle 86 drives the mounting plate 6 forward, and the mounting plate 6 pushes the movable plate 82 forward through the linkage rod 85, thereby moving the row of atomizing nozzles 87 to change the spray area of ​​the atomizing nozzles 87, making it convenient to use and achieving uniform spraying of selenium-enriched fertilizer.

[0039] The working principle of this utility model is as follows: During use, water is added to the water chamber through the first inlet 27, and fertilizer is added to the fertilizer tank through the second inlet 28. Then, the second water pump 17 transports the water and fertilizer to the mixing chamber 23. The motor 18 starts, driving the drive rod 19 to rotate. The drive rod 19 drives the stirring blade 20 to rotate, stirring the water and fertilizer to ensure thorough mixing. The mixed solution is then transported to the water storage chamber 32 through the third water pump 13. Then, the rocker handle 48 is turned, causing the first rotating rod 41 to rotate. The first rotating rod 41 drives the drive gear 42 to rotate, which in turn drives the driven gear 44 to rotate. The driven gear 44 then drives the lifting tube 5 to move upwards. When the lifting tube 5 reaches the designated height, the first knob 47 is turned. The first knob 47 causes the inner end of the stud 46 to press against the rubber sleeve 431, thereby restricting the rotation of the second rotating rod 43, which in turn restricts the rotation of the driven gear 44. The driven gear 44 restricts the movement of the lifting tube 5, thus raising the lifting tube 5. The downcomer 5 is fixed at a designated height, and then the first water pump 9 is started. The first water pump 9 delivers the solution to the water supply pipe 10 through the liquid delivery pipe 30 and the downcomer pipe 5, and then delivers it to the atomizing nozzle 87 through the water supply pipe 10. The solution is sprayed out from the atomizing nozzle 87 to spray fertilizer onto the Chinese toon. When it is necessary to adjust the fertilization range, the user grasps the control handle 86 and moves it back and forth, which drives the control plate 83 to move back and forth. The linkage rod 85 moves back and forth under the action of the control plate 83. The linkage rod 85 drives the movable plate 82 to move back and forth on the support plate 81, thereby changing the spraying range of the atomizing nozzle 87 at the bottom of the movable plate 82, so as to adjust the spraying radius. Turning the handle 12 left and right moves the mounting plate 6 left and right, thereby moving the variable diameter spray device 8 on the upper part of the mounting plate 6 left and right, thereby driving the row of atomizing nozzles 87 to move left and right, so as to change the spraying range of the atomizing nozzles 87, making it convenient to use, further expanding the fertilization range, and achieving uniform spraying of selenium-rich fertilizer.
