[0002] As an important fruit tree variety, navel orange is widely planted around the world. During the cultivation process of navel orange, the supply of nutrient solution has a vital impact on the healthy growth of the plant and the yield and quality of the fruit.

[0003] Existing nutrient solution spraying devices usually move to the navel orange planting area first, and then directly spray the nutrient solution on the navel orange plants through the nozzle. However, most of the current devices can only achieve a single spraying method, such as only spraying from the top or the side, and cannot be flexibly adjusted according to the specific growth status and distribution of the navel orange plants. This results in low utilization of the nutrient solution and cannot meet the nutrient needs of the navel orange plants at different growth stages, which is relatively inconvenient.

[0004] Therefore, it is necessary to design a nutrient solution spraying device for navel orange planting that can spray by top spraying, side spraying and injecting nutrient solution at the rhizome according to the different distribution and growth status of navel orange plants, which is convenient for flexible adjustment and improves the utilization rate of nutrient solution. Summary of the invention

[0005] In order to overcome the disadvantage that most of the current devices can only realize a single spraying mode, such as only spraying through the top or the side, and cannot be flexibly adjusted according to the specific growth status and distribution of the navel orange plants, which leads to low utilization rate of the nutrient solution and cannot meet the nutrient needs of the navel orange plants at different growth stages, which is relatively inconvenient, the present invention provides a nutrient solution spraying device for navel orange planting, which can spray by top spraying, side spraying and injecting nutrient solution at the rhizome according to the different distribution and growth status of the navel orange plants, is convenient for flexible adjustment, and improves the utilization rate of the nutrient solution.

[0039] like Figure 1-Figure 4 As shown, the spray mechanism 3 includes a mounting frame 30, a rotating shaft 31, a rotating wheel 32, a shunt pipe 33, a threaded sleeve 34, a spray pipe 35 and a threaded butt pipe 36. The mounting frame 30 is located above the guide frame 2. Handles are provided on the front and rear sides of the lower part of the mounting frame 30 for easy grasping and moving. The left and right parts of the mounting frame 30 are rotatably connected to the upper and lower rotating shafts 31. The front and rear parts of the rotating shaft 31 are both connected to the rotating wheels 32. The rotating wheels 32 are in contact with the adjacent guide frame 2. The upper sides of the front and rear parts of the mounting frame 30 are connected to the shunt pipe 33. The left and right parts of the shunt pipe 33 are both provided with valves for controlling the circulation of the nutrient solution. The upper right part of the shunt pipe 33 is connected to the threaded sleeve 34. A spray pipe 35 is placed between the support columns 1. The left and right parts of the spray pipe 35 are rotatably connected to the threaded butt pipe 36, and the threaded butt pipe 36 can be threadedly connected to the threaded sleeve 34.

[0040] When using the device, firstly, the support column 1 is built in the navel orange planting nutrient solution spraying area, and then the nutrient solution is externally connected through the left part of the shunt pipe 33. When it is necessary to spray the higher navel orange plants, the valve on the left part of the shunt pipe 33 can be opened to allow the nutrient solution to spray upward and then fall on the navel orange plants and fruits. At the same time, the handle is held to move the mounting frame 30 left and right, driving the rotating wheel 32 to rotate and move, so that the rotating shaft 31 rotates, and the nutrient solution is sprayed on the navel orange plants near the device. When it is necessary to spray the navel orange plants on both sides at the same time, the valve on the right part of the shunt pipe 33 can be opened to allow the nutrient solution to spray out from the right side of the shunt pipe 33, so that the navel orange plants can be sprayed by top spraying or side spraying according to the distribution of the navel orange plants. , which is convenient for adapting to different usage requirements and has high flexibility in use. When the navel orange plants are planted densely and widely, the spray pipe 35 can be taken out from the guide frame 2, and then the threaded butt pipe 36 and the threaded sleeve 34 can be connected, and then the threaded butt pipe 36 can be rotated so that the threaded butt pipe 36 moves under the action of the thread, and the spray pipe 35 is installed between the two groups of mounting frames 30 through the threaded butt pipe 36, so that the nutrient solution enters the spray pipe 35 through the shunt pipe 33, and the nutrient solution is discharged from the spray pipe 35, so that the spray pipe 35 can be externally connected according to the spraying range, which is convenient for spraying nutrient solution on the densely planted and widely planted navel orange plants, ensuring that each plant can be evenly covered in a large orchard, thereby improving the spraying efficiency.

[0041] like Figure 1 , Figure 5 and Figure 6As shown, a side spray mechanism 4 is also included, which includes a fixed seat 40, a torsion spring 41, a spray plate 42, a hose 43, a connecting piece 44 and an extrusion plate 45. The front and rear sides of the upper part of the mounting frame 30 are connected to the fixed seat 40, and the fixed seat 40 is rotatably connected to the spray plate 42. The left and right parts of the spray plate 42 are connected to the adjacent fixed seats 40 with a torsion spring 41. The upper side of the spray plate 42 is connected to a hose 43, and the hose 43 is clamped with the adjacent diversion pipe 33. The inner side of the lower part of the spray plate 42 is connected to a connecting piece 44, and the outer side of the middle part of the guide frame 2 is connected to an extrusion plate 45, and the connecting piece 44 is in contact with and cooperates with the adjacent extrusion plate 45.

[0042] When the side spray mechanism 4 of the device is used, sparsely distributed navel orange plants can be side sprayed. When the navel orange plants are sparsely distributed, the hose 43 can be connected to the shunt pipe 33, and then the mounting frame 30 is moved to drive the connecting member 44 to move. The connecting member 44 contacts and cooperates with the extrusion plate 45 to drive the spray plate 42 to rotate outward on the fixing seat 40. The torsion spring 41 recovers after deformation, driving the spray plate 42 to rotate and reset, so that the spray plate 42 continuously swings during the movement, so that the nutrient solution is sprayed from the spray plate 42 through the hose 43. The swing of the spray plate 42 makes the nutrient solution spraying range wider, so that the spray plate 42 can swing during the moving of the mounting frame 30, expand the nutrient solution spraying range, and facilitate the side spraying of sparsely distributed navel orange plants, thereby reducing the waste of nutrient solution.

[0043] like Figure 1 and Figure 7 As shown, a moving mechanism 5 is also included, and the moving mechanism 5 includes a pulley 50, a transmission belt 51 and a hub motor 52. The middle part of the rotating shaft 31 is connected to the pulley 50, and the transmission belt 51 is wound around the pulleys 50. The hub motor 52 is installed in the upper part of the mounting frame 30, and the hub motor 52 is in contact with the transmission belt 51.

[0044] When the mobile mechanism 5 of the present device is used, the nutrient solution can be automatically moved and sprayed. When the range to be sprayed is wide, the hub motor 52 can be started, and the transmission belt 51 is rotated by the hub motor 52, which drives the pulley 50 to rotate, so that the rotating shaft 31 is rotated, and the rotating wheel 32 is driven to rotate, so that the mounting frame 30 is moved, so that the nutrient solution can be automatically moved and sprayed, saving manpower and time, and improving the efficiency of nutrient solution spraying.

[0045] like Figure 1 , Fig.11 and Fig.12As shown, a height adjustment mechanism 7 is also included, and the height adjustment mechanism 7 includes an embedded seat 70, a pin 71 and a limit piece 72. The outside of the support column 1 is slidably connected to the embedded seat 70. The lower part of the embedded seat 70 is a conical structure for easy fixation. The upper part of the support column 1 is connected with a pin 71 through a docking hole. The pin 71 passes through the adjacent embedded seat 70. The limit piece 72 is connected to the pin 71, and the limit piece 72 is in contact with the adjacent embedded seat 70.

[0046] When the height adjustment mechanism 7 of the device is used, the height of the device can be adjusted. When it is necessary to spray nutrient solution on navel orange plants of different heights, the embedded seat 70 can be inserted into the ground, and then the support column 1 can be adjusted and moved on the embedded seat 70, driving the position of the guide frame 2 and the mounting frame 30 to move. After the adjustment is completed, the pin 71 can be inserted between the support column 1 and the embedded seat 70, and then the limiting member 72 can be stuck on the pin 71. The pin 71 is limited by the limiting member 72, so that the height of the device can be adjusted, which is convenient for spraying nutrient solution on navel orange plants of different heights and improving the flexibility of using the device.

[0047] like Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, it also includes a rhizome maintenance mechanism 6, which includes a docking seat 60, a docking piece 61, a mounting plate 62, a cylinder 63 and an injection pipe 64. The lower sides of the front and rear parts of the mounting frame 30 are connected to the docking seat 60, the docking piece 61 is clamped on the docking seat 60, the lower part of the docking piece 61 is clamped on the mounting plate 62, the outer side of the mounting plate 62 is connected to the cylinder 63, and the telescopic end of the cylinder 63 is connected to the injection pipe 64.

[0048] When the root and stem maintenance mechanism 6 of the device is used, the nutrient solution can be directly injected into the root and stem of the malnourished navel orange plant. When the navel orange plant is malnourished, the docking piece 61 can be clamped on the docking seat 60, and then the mounting plate 62 can be clamped on the docking piece 61, and then the cylinder 63 is started to drive the injection pipe 64 to move downward and insert it into the soil, and then the nutrient solution is connected to the injection pipe 64, so that the nutrient solution is discharged into the soil through the injection pipe 64, so that the nutrient solution can be directly injected into the root and stem of the malnourished navel orange plant, so that the nutrient solution can be quickly absorbed by the root system. Absorption reduces the loss and fixation of nutrients in the soil, ensuring that the plants can quickly obtain the required nutrients. After the height of the support column 1 is adjusted on the embedded seat 70, the mounting plate 62 can be moved outward on the docking piece 61 and taken out, and then the docking piece 61 is superimposed and spliced ​​according to the adjusted height of the support column 1, and then the mounting plate 62 and the docking piece 61 are snap-connected, so that the position of the injection pipe 64 can be flexibly adjusted according to the adjustment of the height of the support column 1, so that the nutrient solution can be directly injected into the rhizome of the malnourished navel orange plant at any time.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
