Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a liquid fertilizer atomization spraying device for crop cultivation. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production. It mainly includes ammonium phosphate fertilizers, water-soluble fertilizers with large amounts of elements, fertilizers with medium amounts of elements, biological fertilizers, organic fertilizers, multi-dimensional field energy concentrated organic fertilizers, etc. Fertilizers can provide nutrients required for crop growth and development, improve crop yield and quality, and are an important means of production in agricultural production. Generally, they are divided into organic fertilizers, inorganic fertilizers, and biological fertilizers. They can also be divided into farmyard fertilizers and chemical fertilizers according to their sources. According to the amount of nutrients contained, they are divided into complete fertilizers and incomplete fertilizers; according to the characteristics of fertilizer supply, they are divided into direct fertilizers and indirect fertilizers; according to the ingredients contained, they are divided into nitrogen fertilizers, potassium fertilizers, trace element fertilizers, and rare earth element fertilizers; in order to meet the needs of agricultural modernization, in addition to continuing to increase production, chemical fertilizer production is moving towards high-efficiency compounding, combined with mechanized fertilization, pipeline fertilizer transportation, and water and fertilizer sprinkler irrigation instrumentation. Liquid ammonia, ammonium polyphosphate, potassium polyphosphate, etc. have become the main fertilizer varieties that are vigorously developed because of their advantages such as high nutrient concentration or few by-components. Many chemical fertilizers also tend to be made into fluid fertilizers, and trace element fertilizers and pesticides are added into them to become multifunctional compound fertilizers, which are convenient for pipeline transportation and fertilization irrigation (sprinkler irrigation, drip irrigation), and have the advantages of saving labor, water and fertilizer. With the development of facility agriculture (such as plastic greenhouses, etc.), the demand for carbon dioxide fertilizers for vegetables, fruits and melons will gradually increase. However, the long-term and large-scale application of chemical fertilizers often leads to environmental pollution. In order to maintain the ecological balance of agriculture, the use of organic fertilizers in combination with chemical fertilizers should be promoted to meet the nutrient needs of crops while avoiding soil deterioration and environmental pollution.

[0003] Liquid fertilizer is often applied by spraying, which can not only reduce people's labor burden, improve work efficiency, and reduce production costs, but also accurately control the time and dosage of fertilizer application, improve the crop growth environment, and increase crop yields. However, most of the existing liquid fertilizer spraying devices spray downward from above the leaf surface, and crops with dense growth or large leaves are blocked from below and cannot effectively contact the fertilizer, resulting in uneven fertilization and a decrease in crop yields.

The nozzle 104 is fixedly connected and is provided with a spray hole 1041, which penetrates the nozzle 104 and is connected with the exposed tube 101. The liquid fertilizer in the bottle body 301 is torn into water mist through the spray hole 1041 and sprayed out through the spray hole 1041. The spray hole 1041 follows the end of the exposed tube 101 and faces obliquely upward to spray the liquid fertilizer in the water absorption part 1 upward. The nozzle 104 is extended under the dense crops to spray the inner leaf surface and the lower surface of the crops.

[0027] A vertical pipe 103 is provided below the exposed pipe 101, and the vertical pipe 103 is fixedly connected to the exposed pipe 101. The vertical pipe 103 sucks the liquid fertilizer in the bottle body 301 into the exposed pipe 101. A water storage part 102 is provided in the middle section of the vertical pipe 103, and the water storage part 102 is fixedly connected to the vertical pipe 103. The water storage part 102 stores the liquid fertilizer sucked by the vertical pipe 103, and then blows it to the exposed pipe 101 and sprays it out by the power part 202. The water storage part 102 includes a water storage chamber 1021 and a glass ball 1022, and the glass ball 1022 is movably connected to the water storage chamber 1021. When the air pressure in the water storage chamber 1021 decreases, the liquid fertilizer in the vertical pipe 103 pushes up the glass ball 1022 and enters the water storage chamber 1021. When the air pressure in the water storage chamber 1021 increases, the liquid fertilizer squeezes the glass ball 1022 downward, and the glass ball 1022 blocks the mouth of the vertical pipe 103, thereby cutting off the circuit of the liquid fertilizer. A pressing part 2 is provided obliquely below the exposed tube 101, and the pressing part 2 is fixedly connected to the exposed tube 101. The pressing part 2 includes a lever 201, a power part 202 and a pressing shell 203. The lever 201 is movably connected to the power part 202. The rotation of the lever 201 pushes the power part 202 to provide thrust for the power part 202. The lever 201 is rotatably connected to the pressing shell 203.

[0028] The power unit 202 includes an air cavity 2021, one end of which is provided with an air cavity opening 2025, the air cavity opening 2025 connects the air cavity 2021 with the exposed tube 101 and the vertical tube 103, and the piston head 2023 can simultaneously adjust the air pressure in the air cavity 2021, the exposed tube 101 and the vertical tube 103 to complete the spraying of liquid fertilizer.

[0029] A spring 2022 is movably arranged in the air cavity 2021, and a piston head 2023 is fixedly arranged at one end of the spring 2022. The piston head 2023 is slidably arranged in the air cavity 2021. A piston rod 2024 is fixedly arranged in the middle of the other end of the piston head 2023. The piston rod 2024 penetrates the power part 202 and extends to the outside of the air cavity 2021, pushing the piston rod 2024 to move into the air cavity 2021. The piston head 2023 squeezes the spring 2022, the spring 2022 is compressed, the air cavity 2021 becomes smaller, and the internal air pressure increases. When the spring 2022 rebounds, the piston head 2023 moves backward, the air cavity 2021 becomes larger, and the internal air pressure decreases.

[0030] A lever 201 is provided on the outside of the piston rod 2024, and the lever 201 includes a driven rod 2012, which is movably connected to the piston rod 2024, and an active rod 2011 is provided at one end of the driven rod 2012, and the driven rod 2012 is fixedly connected to the active rod 2011, and a cross bar 2013 is provided at the tail end of the active rod 2011, and the cross bar 2013 is rotatably connected to the active rod 2011, and the cross bar 2013 is fixedly connected to the pressing shell 203, and the active rod 2011 penetrates the pressing shell 203 and extends outside the pressing shell 203. By pressing the active rod 2011 outside the pressing shell 203, thrust can be provided for the power part 202, and the pressing shell 203 protects the power part 202 to prevent it from being damaged by external force.

[0031] A bottle body 3 is provided below the pressing shell 203, and the bottle body 3 includes a bottle body 301 and a bottle cap 302. The bottle cap 302 is fixedly connected to the pressing shell 203, and the bottle cap 302 is threadedly connected to the bottle body 301. The bottle body 301 can be removed by unscrewing the bottle cap 302, and liquid fertilizer can be loaded into the bottle body 301. The water absorption part 1 passes through the pressing shell 203 and the bottle cap 302, and the end of the vertical pipe 103 is extended into the bottom of the bottle body 301. The pressing shell 203 and the bottle cap 302 extend the water absorption part 1 into the bottle body 301 and fix it, so as to provide liquid fertilizer for spraying to the nozzle 104.

[0032] Unscrew the bottle cap 302, add a proper amount of liquid fertilizer into the bottle body 301, then screw on the bottle cap 302, hold the bottle body near the bottle cap 302, and extend the nozzle 104 into the crop. Since the exposed tube 101 is long and in a "Z" shape, the nozzle 104 can be extended under the lush crop leaves to spray the inner leaf surface and the lower surface of the crop, so that all crops can fully contact the liquid fertilizer, so that the fertilization is more uniform and the crop yield is guaranteed. Aim the nozzle 104 at the crop that needs to be sprayed with fertilizer, press the active rod 2011, the active rod 2011 rotates around the cross bar 2013, drives the driven rod 2012 to rotate inward, the driven rod 2012 pushes the piston rod 2024 to move, and the piston rod 2024 pushes the piston head 2023 moves into the air chamber 2021 and compresses the spring 2022. As the spring 2022 is compressed, the air in the air chamber 2021 is pushed into the exposed tube 101 and the vertical tube 103 by the piston head 2023 and discharged from the exposed tube 101, releasing the active rod 2011. The pressure on the active rod 2011 disappears, and the pressure on the driven rod 2012 also disappears successively, losing the thrust on the piston rod 2024. Under the action of the rebound force of the spring 2022, the piston head 2023 is pushed to the rear of the air chamber 2021. The piston rod 2024 moves outward with the piston head 2023 and pushes the driven rod 2012. The driven rod 2012 rotates around the cross bar 2013, driving the active rod 2011 to return When the piston head 2023 is pushed to the rear of the air chamber 2021, the air pressure in the air chamber 2021 is lower than the standard atmospheric pressure, and the air in the water storage chamber 1021 flows into the air chamber 2021, so that the air pressure in the water storage chamber 1021 is also lower than the standard atmospheric pressure. Under the action of the air pressure difference, the air in the vertical pipe 103 breaks the glass ball 1022 and enters the water storage chamber 1021. When all the air in the vertical pipe 103 is sucked into the water storage chamber 1021, the active rod 2011 is pressed and released again, and the liquid fertilizer in the bottle body 301 is sucked into the water storage chamber 1021. The active rod 2011 is pressed repeatedly, and the piston head 2023 moves forward to compress the air in the air chamber 2021, and the air pressure in the air chamber 2021 is greater than the standard atmospheric pressure. Quasi-atmospheric pressure presses air into the exposed tube 101 and the vertical tube 103, and the glass ball 1022 in the vertical tube 103 blocks the lower outlet of the water storage chamber 1021 under the combined effect of its own weight and pressure, and seals the liquid fertilizer in the water storage chamber 1021, while the air in the air cavity 2021 can only be discharged from the exposed tube 101. At this time, the flow rate of the air in the exposed tube 101 is relatively large. It can be known from the Bernoulli principle that the pressure of the air in the exposed tube 101 is relatively small, and the liquid fertilizer in the water storage chamber 1021 flows toward the exposed tube 101 with low pressure, and quickly flows to the nozzle 104 driven by the air flow, and forms water mist after being torn by the spray hole 1041 and sprayed around the crops. The active rod 2011 is pressed repeatedly, and the spraying operation can be carried out continuously.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
