[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To address the technical problem that top-down spraying of foliar fertilizer only effectively sprays the front of leaves while neglecting the back, this invention provides a foliar fertilizer irrigation device. This device enables multi-layered, lateral spraying of foliar fertilizer on both sides of the plant, forming a multi-layered, partially overlapping umbrella-shaped lateral spraying area. This allows the fertilizer to penetrate the gaps between overlapping leaves in the longitudinal space, spraying the inner leaves. Through the lower umbrella-shaped spraying area, the back of the leaves is sprayed from bottom to top. This lateral spraying also allows spraying the back of opposing leaves. Furthermore, by moving the device along the longitudinal direction of the plant array, it can create forward and backward angles, penetrating the gaps between overlapping leaves at multiple angles, resulting in a more comprehensive spraying of both the front and back of the leaves.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of the foliar fertilizer irrigation device in one embodiment of the present invention. The foliar fertilizer irrigation device includes a walking frame 1, a linear drive mechanism 2, an irrigation frame 3, and a liquid supply mechanism 4. The walking frame 1 is the main frame, erected on the farmland, and has a movable function, allowing it to be pushed and moved on the ground. Combined with the mechanically driven spraying structure, it forms a semi-automatic device that can spray foliar fertilizer over a larger area of ​​farmland under manual pushing. The linear drive mechanism 2 is mounted on the walking frame 1 and has a movable end that moves along the walking frame 1. The linear drive mechanism 2 can be a lead screw guide pair driven by a motor, with the slider on it being the movable end. The irrigation frame 3 is mounted on the linear drive mechanism 4. The movable end of the driving mechanism 2 has multiple side-spraying nozzles 31 arranged vertically on both sides of the plant and facing each other, forming a multi-layered umbrella-shaped spraying area 301 that sprays from the side onto the plant and partially overlaps, used to cover the height range of the plant leaves that need to be sprayed with foliar fertilizer. The multiple atomizing nozzles 31 are arranged in multiple layers, with two side-spraying nozzles 31 in each layer with opposite spraying directions. At least two layers of atomizing nozzles 31 are required. The lower layer of atomizing nozzles 31 can spray the upper leaves at an upward angle, forming a spray on the back of the leaves. The liquid supply mechanism 4 is installed on the walking frame 1, and its output end is connected to the multiple atomizing nozzles 31 one by one, delivering foliar fertilizer to the atomizing nozzles 31.

[0030] In this embodiment, foliar fertilizer is sprayed laterally in multiple layers through atomizing nozzles 31 on both sides of the plant, forming a multi-layered and partially overlapping umbrella-shaped lateral spraying area 301. This allows the spray to penetrate the gaps between overlapping leaves in the longitudinal space, thus spraying the inner leaves. Through the lower layer of the umbrella-shaped spraying area, the back of the leaves facing upwards is sprayed. Through symmetrical spraying on both sides, the spray can also penetrate the gaps to spray the back of the opposing leaves. Since the umbrella-shaped spraying area diffuses in three dimensions in all directions, and moves along the longitudinal planting array direction of the plants, it can also form front and back angles for spraying the plants, penetrating the gaps in the overlapping leaves at multiple angles, thus forming a relatively comprehensive spraying of both the front and back of the leaves.

[0031] It should be noted that atomizing nozzles that form a conical spray area are generally called full-cone atomizing nozzles or simply cone nozzles. These nozzles are designed to produce a uniformly distributed spray of droplets covering a circular area, resembling a cone in shape. Fan-shaped atomizing nozzles and rotary atomizing nozzles can also create similar spray areas.

[0032] In one feasible embodiment, the bottom of the walking frame 1 is equipped with four casters 101 for movement, and the four casters 101 are distributed at the four corners of the walking frame 1.

[0033] Understandably, the walking frame 1 can also be a frame fixed on the field. When the field area is small, the frame is easy to cover, and the cost is not high, the walking frame 1 can be fixed.

[0034] It should be noted that the universal wheel 101, as the walking structure of the walking frame 1, is only one feasible embodiment. The walking structure of the walking frame 1 can also adopt a structure of slider and guide rail. The slider is connected to the walking frame 1, while the guide rail is laid flat along the side of the field, and the slider is slidably connected to the guide rail to guide the sliding direction of the walking frame 1.

[0035] Furthermore, if the width of a single plant is relatively wide, a top-spraying atomizing nozzle can be added to the irrigation frame 3 for coordinated spraying.

[0036] In one embodiment, please refer to Figure 1 and Figure 2To accommodate foliar fertilizer application to plants of different widths, the spacing between the two atomizing nozzles 31 is adjustable. A crossbar 21 is provided on the movable end of the linear drive mechanism 2. The irrigation frame 3 includes an adjusting member 32 and vertical rods 33. A pair of vertical rods 33 are connected to the adjusting member 32 in a one-to-one correspondence, and are detachably connected to the crossbar 21 through the adjusting member 32. The atomizing nozzles 31 are installed on the vertical rods 33. By disassembling the adjusting member 32, the spacing between the two vertical rods 33 is adjusted, and then reinstalled, thereby adjusting the spacing between the two vertical rods 33, and thus adjusting the interval distance between the atomizing nozzles 31 on the two vertical rods 33 to accommodate spraying plants of different widths.

[0037] In one embodiment, please refer to Figure 4 In order to spray multiple rows of plants in one acre of farmland at the same time, with a row spacing between each row of plants, the irrigation frame 3 is of multiple types. The multiple irrigation frames 3 are arranged at equal intervals along the length of the crossbar 21. That is, the irrigation frame 3 is placed on both sides of the row spacing of each row of plants and moves linearly along the length of each row of plants from one end to the other, thus completing the foliar fertilizer spraying of the plants.

[0038] In this embodiment, the skeleton of the walking frame 1 is made of hollow tubing to facilitate lightweight movement.

[0039] In one embodiment, please refer to Figure 1 For ease of adjustment and installation, the adjusting component 32 includes a first sliding sleeve 321 and a first locking component 322. The first sliding sleeve 321 is slidably fitted onto the crossbar 21 and can be slidably adjusted along the length of the crossbar 21. The first locking component 322 is installed on the first sliding sleeve 321 and is used to lock the relative sliding between the first sliding sleeve 321 and the crossbar 21. When locked, the position is locked; when unlocked, it can be slid and disassembled.

[0040] Understandably, the first locking element 322 can be a bolt. Tightening it and abutting against the crossbar 21 will lock it in place. Conversely, loosening the bolt will unlock it. Then, the first sliding sleeve 321 can be removed from the crossbar 21.

[0041] Optionally, the first sliding sleeve 321 is in the shape of an inverted J, which makes it easy to hang on the crossbar 21 and easy to disassemble.

[0042] In one embodiment, please refer to Figure 1To adapt to different foliar fertilizer spraying heights and ranges, the atomizing nozzle 31 includes a second sliding sleeve 311, a second locking member 312, and a nozzle body 313. The second sliding sleeve 311 is slidably fitted onto the irrigation frame 3, and the nozzle body 313 is fixedly connected to the second sliding sleeve 311. The second locking member 312 is installed on the second sliding sleeve 311 and is used to lock the relative sliding between the second sliding sleeve 311 and the irrigation frame 3. By unlocking the sliding lock, the second sliding sleeve 311 can be slid along the vertical rod 33 to adjust the height of the nozzle body 313 and the distance between the upper and lower nozzles, thereby adjusting the spraying height and coverage range. The second locking member 312 can also be a bolt; tightening it and abutting against the vertical rod 33 forms a lock, while loosening the bolt unlocks it, allowing the second sliding sleeve 311 to be removed from the vertical rod 33.

[0043] Optionally, the second sliding sleeve 311 is cylindrical in shape, which makes it easy to fit onto the vertical rod 33 of the irrigation frame 3 and prevents it from tilting.

[0044] Understandably, depending on the coverage area and the spray range of the nozzles, the number of atomizing nozzles 31 can be increased or decreased according to actual needs.

[0045] In one embodiment, please refer to Figure 1 and Figure 3 To supply foliar fertilizer to each atomizing nozzle 31, the liquid supply mechanism 4 includes a liquid storage tank 41, a liquid supply pump 42, a guide rail 43, a first pipe 44, and a second pipe 45. The liquid storage tank 41 is located on one side of the walking frame 1 and stores foliar fertilizer. The inlet end of the liquid supply pump 42 is connected to the liquid storage tank 41, and the outlet end of the liquid supply pump 42 is connected to the first pipe 44. The other end of the first pipe 44 is connected to the second pipe 45. The second pipe 45 has multiple branch pipes that are connected one-to-one with each atomizing nozzle 31. The liquid supply pump 42 pumps the foliar fertilizer in the liquid storage tank 41 through the first pipe 44 and the second pipe 45 to each branch pipe, and then supplies it to the atomizing nozzle 31 for spraying.

[0046] Furthermore, in order to guide the first tube 44 to be pulled and pushed back and prevent it from falling onto the farmland, the guide rail 43 is connected to the top of the walking frame 1, and a strip-shaped opening 401 is opened at its bottom for the second tube 45 to pass through downwards. The diameter of the first tube 44 is larger than the diameter of the second tube 45, and it is slidably connected in the guide rail 43. The second tube 45 is restricted to sliding in the guide rail 43 by the strip-shaped opening 401, while the first tube 44 can pass through the strip-shaped opening 401 to the bottom, extending out multiple branch tubes and then connecting to the corresponding atomizing nozzles 31 one by one.

[0047] Understandably, when the irrigation frame 3 moves away from the storage tank 41, it pulls the first tube 44 to slide within the guide rail 43; when the irrigation frame 3 moves closer to the storage tank 41, it pushes the first tube 44 to slide along the guide rail 43 and drop it to the top of the storage tank 41.

[0048] In one embodiment, in order to control spraying when the number of atomizing nozzles 31 on one side is greater than two, a valve is installed between the atomizing nozzle 31 and the corresponding branch pipe. When spraying is not required from three or more atomizing nozzles 31, the valves of the unnecessary atomizing nozzles 31 can be closed.

[0049] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: Based on the required range of leaf spray height, the spacing and height of multiple atomizing nozzles 31 are adjusted. After adjustment, the position is locked by the second locking member 312. Then, the linear drive mechanism 2 is activated to drive the irrigation frame 3 to move along the length of each row of plants. Through lateral multi-layer atomized spraying of foliar fertilizer, a multi-layered and partially overlapping umbrella-shaped lateral spraying area 301 is formed, which has a good spraying effect on both the front and back of the leaves. If the farmland area is large, in order to save costs, a semi-automatic operation is adopted. The walking frame 1 is moved manually to other farmland areas for foliar fertilizer spraying.

[0050] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
