Description

Technical Field

[0001] This utility model relates to the field of crop fertilization technology, specifically a crop foliar fertilization device. Background Technology

[0002] For example, soybeans can be fertilized with foliar fertilizer, which allows the crop to absorb nutrients directly through the leaves and quickly replenish the nutrients (such as nitrogen, phosphorus, potassium and trace elements) needed for crop growth. Compared with soil fertilization, foliar fertilizer has the characteristics of being fast-acting, requiring less dosage and being environmentally friendly.

[0003] With the development of large-scale agricultural planting, conventional ground fertilization equipment can no longer meet the needs of efficient foliar fertilization of large areas of crops. Instead, drone fertilization equipment is used to foliar fertilize crops, such as the spraying fertilization drone proposed in patent application number "CN202420732068.8".

[0004] However, in existing technologies, when drones apply fertilizer, they usually spray the fertilizer directly above the crops. When using drones to spray foliar fertilizer directly from above the crops, the upper leaves of the crops will block the lower leaves, resulting in the foliar fertilizer not being evenly applied to the lower leaves of the crops. Utility Model Content

[0005] The purpose of this invention is to provide a foliar fertilization device for crops to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A foliar fertilization device for crops includes a fertilizer box installed at the bottom of a drone. A vertical connecting pipe is fixedly connected to the bottom of the fertilizer box. The vertical connecting pipe has a cavity inside for conveying water-soluble fertilizer. An adjustable inclined fertilizer pipe is provided on both sides of the vertical connecting pipe. Multiple atomizing nozzles are evenly arranged on one side of the inclined fertilizer pipe.

[0008] Both sides of the bottom of the vertical connecting pipe are fixedly connected to a connecting hose, and a control valve is fixedly installed on the connecting hose. The end of the connecting hose away from the vertical connecting pipe is fixedly connected to the inclined fertilizer pipe, which is used to transport the water-soluble fertilizer in the vertical connecting pipe to the inclined fertilizer pipe.

[0009] Preferably, a water pump is fixedly connected to the bottom of the fertilizer box, the inlet of the water pump extends into the interior of the fertilizer box, and a delivery pipe is fixedly connected to the outlet of the water pump. One end of the delivery pipe is fixedly connected to one side of the top of the vertical connecting pipe.

[0010] Preferably, the bottom of the vertical connecting pipe is provided with a three-end bracket with an inverted T-shaped design. The top end of the three-end bracket is fixedly connected to the vertical connecting pipe, and the other two ends of the three-end bracket are rotatably connected to the bottom ends of the two inclined fertilizer pipes respectively.

[0011] Preferably, the outer surface of the vertical connecting pipe is provided with threads, a control sleeve is threadedly connected to the vertical connecting pipe, and a drive sleeve is slidably connected to the vertical connecting pipe below the control sleeve.

[0012] Preferably, both sides of the drive sleeve are fixedly connected to a connecting shaft, and the two ends of the connecting shaft are rotatably connected to a drive connecting plate. The ends of the two drive connecting plates away from the connecting shaft are respectively rotatably connected to both sides of the inclined fertilizer pipe for adjusting the inclination of the inclined fertilizer pipe.

[0013] Preferably, a control ring is fixedly connected to the bottom of the control sleeve, an upper drive ring is sleeved on the control sleeve above the control ring, a lower drive ring is fixedly connected to the top of the drive sleeve below the control ring, and multiple fixed shafts are fixedly connected between the upper drive ring and the lower drive ring.

[0014] The beneficial effects of this utility model are:

[0015] This invention utilizes a drone to propel a fertilization device at low altitude between two rows of crops. Combined with an inclined fertilization pipe and atomizing nozzle, the device sprays water-soluble fertilizer, a mixture of foliar fertilizer and water, onto the leaves at an angle.

[0025] like Figure 1 and Figure 4 A foliar fertilization device for crops includes a fertilizer box 1 installed at the bottom of a drone. The top of the fertilizer box 1 is provided with a fertilizer injection port that is sealed by an end cap. The injected fertilizer is a water-soluble fertilizer formed by mixing foliar fertilizer and water.

[0026] The drone includes a body 100, and two symmetrical support frames 200 are fixedly connected to the bottom of the body 100. The support frames 200 adopt an L-shaped design and can provide auxiliary support for the fertilizer box 1 at the bottom. There are fixing bolts 300 on the support frames 200. The fixing bolts 300 pass through the screw holes on both sides of the support frames 200 and are threaded to connect with the fertilizer box 1, so that the fertilizer box 1 is installed on the bottom of the drone body 100.

[0027] like Figure 1 and Figure 2 The bottom of the fertilizer box 1 is fixedly connected to a vertical connecting pipe 2. The top and bottom of the vertical connecting pipe 2 are closed ends and are not directly connected to the fertilizer box 1. The vertical connecting pipe 2 has a cavity inside for conveying water-soluble fertilizer. The vertical connecting pipe 2 has an adjustable inclined fertilizer pipe 3 on both sides. Multiple atomizing nozzles 4 are evenly arranged on one side of the inclined fertilizer pipe 3.

[0028] like Figure 2 and Figure 3 Both sides of the bottom of the vertical connecting pipe 2 are fixedly connected to the connecting hose 5. The connecting hose 5 is fixedly installed with the control valve 501. The control valve 501 is a manual control valve. When only one side of the crops needs to be fertilized, one of the control valves 501 can be closed. The end of the connecting hose 5 away from the vertical connecting pipe 2 is fixedly connected to the inclined fertilizer pipe 3, which is used to transport the water-soluble fertilizer in the vertical connecting pipe 2 to the inclined fertilizer pipe 3.

[0029] like Figure 1 and Figure 2 A water pump 6 is fixedly connected to the bottom of the fertilizer box 1. The inlet of the water pump 6 extends into the interior of the fertilizer box 1. A delivery pipe 7 is fixedly connected to the outlet of the water pump 6. One end of the delivery pipe 7 is fixedly connected to one side of the top of the vertical connecting pipe 2. The water pump 6 is connected to the drone body 100 by a plug-in connection through a wire, so that the water pump 6 draws power from the inside of the drone body 100 and is controlled by the internal circuit of the drone body. Connecting the water pump 6 to the drone for fertilizer control is existing technology and will not be described in detail here.

[0030] like Figure 2 and Figure 3 The bottom of the vertical connecting pipe 2 is provided with a three-end bracket 8 with an inverted T-shaped design. The top of the three-end bracket 8 is fixedly connected to the vertical connecting pipe 2, and the other two ends of the three-end bracket 8 are rotatably connected to the bottom ends of the two inclined fertilizer pipes 3 respectively.

[0031] like Figure 3 and Figure 4 The outer surface of the vertical connecting pipe 2 is provided with threads, and a control sleeve 9 is threadedly connected to the vertical connecting pipe 2. The inner surface of the control sleeve 9 is threaded to achieve a threaded connection with the vertical connecting pipe 2. A drive sleeve 10 is slidably connected to the vertical connecting pipe 2 and located below the control sleeve 9.

[0032] like Figure 3 Both sides of the drive sleeve 10 are fixedly connected to the connecting shaft 11, and the two ends of the connecting shaft 11 are rotatably connected to the drive connecting plate 12. The ends of the two drive connecting plates 12 away from the connecting shaft 11 are respectively rotatably connected to the two sides of the inclined fertilizer pipe 3, which are used to adjust the inclination of the inclined fertilizer pipe 3.

[0033] like Figure 3 and Figure 4 A control ring 13 is fixedly connected to the bottom of the control sleeve 9. An upper drive ring 14 is fitted on the control sleeve 9 above the control ring 13. A lower drive ring 15 is fixedly connected to the top of the drive sleeve 10 below the control ring 13. Multiple fixed shafts 16 are fixedly connected between the upper drive ring 14 and the lower drive ring 15, so that the upper drive ring 14, the lower drive ring 15 and the fixed shafts 16 form a whole and can move together.

[0034] The working principle of the foliar fertilization device for crops provided by this utility model is as follows:

[0035] like Figure 5 , Figure 2 , Figure 3 and Figure 4 When foliar fertilization of crops is required, the fertilization device is installed on the drone. The drone drives the fertilization device to fly at low altitude between two rows of crops. During the flight, the water pump 6 draws water-soluble fertilizer from the fertilizer box 1 and delivers it to the cavity inside the vertical connecting pipe 2 through the delivery pipe 7. Then, it is delivered to the inclined fertilization pipe 3 through the connecting hose 5. Finally, it is sprayed onto the leaves of the crops in an inclined direction through the atomizing nozzle 4.

[0036] When it is necessary to adjust the inclination of the inclined fertilizer pipe 3, the control sleeve 9 can be rotated in different directions. The control sleeve 9 will move up or down. If the control sleeve 9 moves up, it will drive the control ring 13 to move up, which will drive the upper drive ring 14 to move up. The upper drive ring 14 will drive the lower drive ring 15 and drive sleeve 10 to move up through the fixed shaft 16. If the control sleeve 9 moves down, it will drive the control ring 13 to move down, which will drive the lower drive ring 15 and drive sleeve 10 to move down.

[0037] Moving the drive sleeve 10 up or down will cause the drive connecting plate 12 to pull or push the inclined fertilizer pipe 3, causing the inclined fertilizer pipe 3 to rotate on the three-end bracket 8, thereby adjusting the angle of the inclined fertilizer pipe 3.

[0038] Compared with related technologies, the foliar fertilization device for crops provided by this utility model has the following beneficial effects:

[0039] This invention uses a drone to propel a fertilization device at low altitude between two rows of crops. Combined with an inclined fertilizer pipe 3 and atomizing nozzle 4, the device sprays water-soluble fertilizer, formed by mixing foliar fertilizer and water, onto the leaves at an inclined angle. This reduces the obstruction between the upper and lower leaves, allowing for more even application of the foliar fertilizer to the lower leaves of the crops. Furthermore, the inclination of the inclined fertilizer pipe 3 can be adjusted to suit the foliar fertilization of different crops.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
