Description

Technical Field

[0001] This utility model relates to the field of leaf rust control technology, specifically to an adjustable leaf rust control spraying device. Background Technology

[0002] Leaf rust is usually caused by some fungi in the order Rustales, and the types of leaf rust fungi that infect different crops may be different. For example, wheat leaf rust is caused by *Strombyx melilotus*, while legume leaf rust may be caused by *Strombyx melilotus*, etc. It is relatively common in agricultural production and can cause damage to a variety of crops. After crops are infected with leaf rust, it is necessary to spray the crops with control agents for treatment. However, most commercially available equipment currently uses a direct forward spraying method. But given the wide variety of crops susceptible to leaf rust and the significant differences in the height of infected areas at different growth stages, this conventional spraying method struggles to accurately deliver the pesticide to the infected site. Furthermore, because this spraying method keeps the pesticide sprayed roughly horizontally to the crop leaves, it reduces pesticide adhesion to the leaf surface, thus affecting the control effect. Therefore, we propose an adjustable leaf rust control spraying device. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable spraying device for controlling leaf rust.

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: an adjustable leaf rust control spraying device, comprising a trolley, a control box fixed to one side of the trolley, casters on both sides of the lower end of the trolley, a battery box and a first protective box fixed to both sides of the upper end of the trolley, a rotating groove on the upper end of the trolley, a gear cylinder rotatably disposed inside the rotating groove, a first motor fixed to one end of the first protective box, a first gear mounted on the upper end of the first motor, a spiral column disposed inside the gear cylinder, a connecting plate fixed to the upper end of the spiral column, a rotating plate rotatably disposed inside the connecting plate, a second gear fixed to one end of the rotating plate, a second protective box fixed to one end of the connecting plate, a second motor fixed to one end of the second protective box, a third gear disposed at one end of the second motor, an atomizing nozzle penetrating one side of the rotating plate, and a medicine tank and a water pump fixed to the two sides near the center of the upper end of the trolley, with connecting hoses on both sides of the water pump.

[0005] Preferably, the gear cylinder is meshed with the first gear, and the second gear is meshed with the third gear.

[0006] Preferably, one side of the water pump is connected to the medicine tank pipeline via a connecting hose, and the other side of the water pump is connected to the atomizing nozzle pipeline via a connecting hose.

[0007] Preferably, the side wall of the medicine container is provided with a solenoid valve, a third motor is fixed at the center of the upper end of the medicine container, a mixing rod is installed at the lower end of the third motor, an electric push rod and a sealing plug are respectively provided at one end of the upper end of the medicine container, a diversion chamber is installed at the top inside the medicine container, a connecting pipe is fixed on one side of the upper end of the diversion chamber, and multiple sets of high-pressure fan-shaped nozzles are fixed on the side wall and lower end of the diversion chamber.

[0008] Preferably, the lower end of the electric push rod passes through the medicine container and is fixedly connected to the diversion cavity, and the connecting pipe passes through the medicine container and is connected to the diversion cavity pipe.

[0009] Preferably, the number of high-pressure fan-shaped nozzles is sixteen, and the high-pressure fan-shaped nozzles are evenly distributed on the side wall and lower end of the diversion cavity.

[0010] Using the above technical solution, the first motor is started in the forward direction, causing the first motor to drive the gear cylinder to rotate through the first gear. The gear cylinder then pushes out the spiral column, causing the connecting plate to drive the atomizing nozzle to rise through the rotating plate. The nozzle is then adjusted to the desired spraying position according to the crop type and growth stage, and stops when it is lowered. Conversely, it descends when it is lowered. Then, the second motor is started in the forward direction, causing the second motor to drive the rotating plate to rotate through the third gear and the second gear. At this time, the rotating plate drives the atomizing nozzle to rotate together. The nozzle stops when it is perpendicular or nearly perpendicular to the leaf surface. Then, the water pump is started, and the water pump sprays the liquid medicine inside the tank onto the crop through the atomizing nozzle through the connecting hose. This allows the leaf rust control spraying equipment to adjust the height and angle of the atomizing nozzle according to the crop type and growth stage, making it easier for the liquid medicine to form a uniform film on the leaves, increasing the contact time and coverage area between the liquid medicine and the pathogen. Using the above technical solution, the connecting pipe is connected to the water pipe, and then the electric push rod is started to push the diversion chamber down. At the same time, the high-pressure fan-shaped nozzle is opened, so that the high-pressure fan-shaped nozzles on the side wall and lower end of the diversion chamber can perform high-pressure rinsing on the inner wall and bottom of the medicine tank. After rinsing, the solenoid valve is opened to discharge the residue, and then the sealing plug is opened. Water and disinfectant are then poured into the medicine tank, and the third motor is started to drive the mixing rod to mix the water and disinfectant. At this time, the water and cleaning agent will disinfect the inside of the medicine tank while mixing. After disinfection, the solenoid valve is opened to discharge the wastewater. This allows the leaf rust control spraying equipment to rinse and disinfect the inside of the medicine tank, so that there is no residual residue inside the medicine tank and cross-contamination between different control agents is avoided.

It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0014] Example 1: Please see Figure 1-4This utility model provides a technical solution: an adjustable leaf rust control spraying device, including a trolley 1, a control box 2 fixed to one side of the trolley 1, and two movable wheels 3 on both sides of the lower end of the trolley 1. A battery box 4 and a first protective box 5 are fixed to the two sides of the upper end of the trolley 1, respectively. A rotating groove 7 is opened on the upper end of the trolley 1, and a gear cylinder 6 is rotatably arranged inside the rotating groove 7.

A rotating plate 12 is rotatably arranged inside the connecting plate 11, and one end of the rotating plate 12 is fixed. A second gear 13 is fixed, a second protective box 14 is fixed to one end of the connecting plate 11, a second motor 15 is fixed to one end inside the second protective box 14, a third gear 16 is provided at one end of the second motor 15, an atomizing nozzle 17 is provided through one side of the rotating plate 12, a medicine tank 18 and a water pump 20 are fixed on the two sides near the center of the upper end of the trolley 1 respectively, and a connecting hose 21 is provided on both sides of the water pump 20; the gear cylinder 6 is meshed with the first gear 9, and the second gear 13 is meshed with the third gear 16; one side of the water pump 20 is connected to the medicine tank 18 through the connecting hose 21, and the other side of the water pump 20 is connected to the atomizing nozzle 17 through the connecting hose 21.

[0015] Specifically, the first motor 8 is started by the control box 2, causing it to drive the first gear 9 to rotate. The first gear 9 then drives the gear cylinder 6, which meshes with it, to rotate. The gear cylinder 6 then pushes out the internal spiral column 10, causing the spiral column 10 to push the connecting plate 11 upwards. The rotating plate 12 inside the connecting plate 11 then drives the atomizing nozzle 17 upwards. Depending on the crop type and growth stage, the nozzle rises to the desired spraying position and stops; otherwise, it descends. Then, the second motor 15 is started by the control box 2, causing it to drive the third gear 16 to rotate. The third gear 16 then drives the second gear 13 to rotate, causing the second gear... Wheel 13 drives the atomizing nozzle 17 to rotate via rotating plate 12. The atomizing nozzle 17 stops when it is perpendicular or nearly perpendicular to the leaf surface, and rotates to the other side when it is not perpendicular. Then, the trolley 1 is moved by moving wheel 3. At the same time, the water pump 20 is started by control box 2, so that the water pump 20 sprays the liquid medicine inside the medicine tank 18 onto the crop through the atomizing nozzle 17 via connecting hose 21. The leaf rust control spraying equipment can adjust the height of the atomizing nozzle 17 according to the crop type and crop growth stage, and can also adjust the angle of the atomizing nozzle 17, so that the liquid medicine can more easily form a uniform film on the leaves, increasing the contact time and area of ​​action between the liquid medicine and the pathogen.

[0016] Example 2: Please see Figure 1-4This utility model provides a technical solution: an adjustable spraying device for controlling leaf rust, wherein a solenoid valve 19 is provided on the side wall of the medicine tank 18, a third motor 22 is fixed at the center of the upper end of the medicine tank 18, a mixing rod 23 is installed at the lower end of the third motor 22, an electric push rod 25 and a sealing plug 28 are respectively provided at one end of the upper end of the medicine tank 18, a diversion chamber 24 is installed at the top inside the medicine tank 18, a connecting pipe 26 is fixed on one side of the upper end of the diversion chamber 24, and multiple sets of high-pressure fan-shaped nozzles 27 are fixed on the side wall and lower end of the diversion chamber 24; the lower end of the electric push rod 25 passes through the medicine tank 18 and is fixedly connected to the diversion chamber 24, the connecting pipe 26 passes through the medicine tank 18 and is connected to the pipe of the diversion chamber 24; the number of high-pressure fan-shaped nozzles 27 is sixteen, and the high-pressure fan-shaped nozzles 27 are evenly distributed on the side wall and lower end of the diversion chamber 24.

[0017] Specifically, when the medicine tank 18 needs to be cleaned, the connecting pipe 26 is connected to the water pipe, and then the electric push rod 25 is started in the forward direction via the control box 2. At this time, the electric push rod 25 will push the diversion chamber 24 down in the medicine tank 18, and at the same time, the high-pressure fan-shaped nozzle 27 will be opened, so that the high-pressure fan-shaped nozzle 27 on the side wall of the diversion chamber 24 will perform high-pressure rinsing on the inner wall of the medicine tank 18. When the diversion chamber 24 is close to the bottom of the medicine tank 18, it stops. At this time, the high-pressure fan-shaped nozzle 27 at the lower end of the diversion chamber 24 will perform high-pressure rinsing on the bottom of the medicine tank 18. Then, the electric push rod 25 is started in the reverse direction via the control box 2, so that the electric push rod 25 will drive the diversion chamber 24 up. At this time, the high-pressure fan-shaped nozzle 27 will spray the medicine tank. The inside of tank 18 is rinsed twice. The rinsing stops when the diversion chamber 24 returns to its original position. After rinsing, the solenoid valve 19 is opened to discharge the residue. Then the sealing plug 28 is opened, and water and disinfectant are poured into the tank 18. The third motor 22 is then started through the control box 2, which drives the mixing rod 23 to mix the water and disinfectant. At this time, the water and cleaning agent will disinfect the inside of the tank 18 while they are mixing. After disinfection, the solenoid valve 19 is opened to discharge the wastewater. This allows the leaf rust control spraying equipment to rinse and disinfect the inside of the tank 18, ensuring that there are no residual pesticide residues inside the tank 18 and avoiding cross-contamination between different control agents.
