Description

Technical Field

[0001] This utility model belongs to the technical field of pesticide spraying devices, specifically relating to a pesticide spraying device for wheat cultivation. Background Technology

[0002] Wheat is an important food crop in my country, and pesticide spraying is an important part of the prevention and control of diseases and pests during its growth process. The equipment used mainly includes traditional manual sprayers and electric sprayers.

[0003] Manual sprayers, such as backpack sprayers, rely on the operator manually pressing a lever to generate pressure. This results in low operational efficiency, making it difficult to meet the needs of large-scale planting. The manually generated pressure is unstable and difficult to maintain, leading to uneven atomization of the pesticide solution, insufficient range, and uneven application to crops, thus affecting the control effect. Another commonly used technology is the trolley-type electric sprayer. Its pressurization system often uses diaphragm pumps or centrifugal pumps to directly pressurize the entire storage tank. This results in slow pressure build-up and sluggish start-stop response, making it unable to flexibly adapt to changes in canopy height and density at different growth stages of wheat.

[0004] Therefore, there is an urgent need for a pesticide spraying device for wheat cultivation to achieve efficient, uniform, labor-saving and safe pesticide spraying operations. Utility Model Content

[0005] The purpose of this invention is to provide a pesticide spraying device for wheat cultivation, which has the advantages of automated pressurization and simple operation, and solves the problems of relying on manual pressurization, high labor intensity and unstable pressure affecting atomization effect in the prior art.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figure 1-3 As shown, a pesticide spraying device for wheat cultivation includes a vehicle body 1, which serves as the basic frame of the device, supporting and connecting all other components. The vehicle body 1 is welded from lightweight yet robust galvanized steel pipes or aluminum alloy, ensuring structural stability and a low center of gravity to prevent tipping. An integrated battery powers the device. Wheels are located on the front and rear sides of the vehicle body 1, allowing for flexible movement. A push handle 3 is located at the rear of the vehicle body 1, providing a pushing mechanism for the operator. The handle portion of the push handle 3 can be covered with a non-slip rubber sleeve to improve grip comfort and increase friction.

[0025] The vehicle body 1 is equipped with a liquid storage tank 4 on its top. The liquid storage tank 4 is a cylindrical structure with an open top, and it stores the prepared pesticide solution. The liquid storage tank 4 is made of corrosion-resistant polyethylene (PE) or stainless steel to avoid chemical reaction with the pesticide. The open top facilitates filling and cleaning.

[0026] The front end and both sides of the liquid storage tank 4 are equipped with fixed brackets 5. The fixed brackets 5 are equipped with push rod motors 6. The fixed brackets 5 are used to raise and support the push rod motors 6. The push rod motors 6 are vertically connected to the lifting rods 7. The end of the lifting rods 7 extends into the interior of the liquid storage tank 4 and is fixedly connected to the piston plate 8. The push rod motors 6 provide stable and controllable linear thrust. The piston plate 8 is fixedly connected to the end of the lifting rods 7. The piston plate 8 and the inner wall of the liquid storage tank 4 form a tight dynamic seal. The lifting rods 7 can effectively pressurize the liquid during the downward pressing process. The piston pressurization method is highly efficient, and the pressure output is stable and constant, achieving a good atomization effect.

[0027] A fixed rod 9 is installed on the rear side of the push rod motor 6, and a control panel 10 is installed on the fixed rod 9. The control panel 10 integrates control and human-machine interface. A liquid outlet pipe 11 is installed on the side wall of the vehicle body 1, and a spray head 12 is installed at the end of the liquid outlet pipe 11. The liquid outlet pipe 11 delivers the liquid medicine. The liquid outlet pipe 11 is a rigid pipe. The liquid outlet pipe 11 is connected to the bottom of the liquid storage tank 4 through an EPDM rubber tube that is resistant to pesticide corrosion. The spray head 12 atomizes and sprays the pressurized liquid medicine.

[0028] The specific design of the aforementioned key components will be discussed in detail below:

[0029] The piston plate 8 is fitted with a sealing ring on its outer circumference, which dynamically seals against the inner wall of the storage tank 4. The piston plate 8 is made of lightweight and corrosion-resistant polytetrafluoroethylene (PTFE) or nylon, and its outer circumference is machined with one or more annular grooves. Nitrile rubber sealing rings are embedded in these annular grooves. The outer diameter of the sealing ring is slightly larger than the inner diameter of the storage tank 4, and it maintains tight contact with the tank wall through elastic deformation, forming a reliable dynamic seal. When the lifting rod 7 is pressed down, it effectively pressurizes the liquid below the piston plate 8, forcing the liquid to flow out from the outlet pipe 11, providing a stable, leak-free, and efficient pressurization method. Compared to traditional integral tank pressurization, piston-type pressurization builds pressure faster and responds more promptly.

[0030] The control panel 10 is equipped with an LCD screen and control buttons. The control panel 10 integrates a control chip and is electrically connected to the push rod motor 6. The housing of the control panel 10 is waterproof, and the internal control chip protects the microprocessor (MCU) connected to the push rod motor 6, battery, and control buttons. The LCD screen can be a low-power segment LCD or dot matrix LCD for displaying system status.

[0031] The spray head 12 has a showerhead structure, with multiple distribution channels inside and a variety of atomizing nozzles evenly distributed around its edges. The showerhead-type spray head 12 has a central chamber from which multiple distribution channels extend radially, each channel connecting to an atomizing nozzle. The atomizing nozzles preferably have vortex vanes or spiral grooves inside, causing the pesticide solution to rotate before spraying. The central chamber and distribution channels ensure that the pesticide solution is evenly distributed to each nozzle. The atomizing nozzles utilize liquid pressure to break it into countless tiny droplets, forming a fine, uniform, and wide-coverage mist field. These fine droplets adhere more easily to wheat leaves, improving pesticide utilization.

[0032] A discharge valve 13 is installed on the discharge pipe 11. The discharge valve 13 is preferably a ball valve made of brass. The discharge valve 13 controls the opening and closing of the liquid pipeline, acting as a manual switch to quickly cut off the flow of liquid when the equipment is paused, moved, or in an emergency. It is quick to operate, reliably sealed, and has low flow resistance. The ball valve only requires a 90-degree rotation to open and close, making it convenient and fast.

[0033] The storage tank 4 has a liquid level observation window 14 on its side wall, and the outer surface of the liquid level observation window 14 is engraved with volume scale lines. The liquid level observation window 14 is made of transparent high-strength polycarbonate sheet and is embedded in the opening on the side wall of the storage tank 4 by a corrosion-resistant sealing strip. The outer surface is laser-engraved with clear volume scale lines in liters. The liquid level observation window 14 provides an intuitive visual window for real-time monitoring of the remaining amount of medicine in the storage tank 4, which facilitates accurate planning of the working area and timely replenishment of the prepared medicine.

[0034] A pressure relief pipe 15 is also connected through the side wall of the liquid storage tank 4. The inlet end of the pressure relief pipe 15 extends into the inner cavity of the liquid storage tank 4, and the outlet end opens to the atmosphere. A one-way valve 16 is installed on the pressure relief pipe 15. The one-way valve 16 is open from the atmosphere to the inside of the liquid storage tank 4. When the piston plate 8 moves upward, a negative pressure is created inside the liquid storage tank 4. The external atmospheric pressure will open the one-way valve 16, allowing air to quickly enter the top cavity of the liquid storage tank 4, balancing the internal and external pressures, and facilitating the rise of the piston plate 8.

[0035] Preferably, the spray head 12 is connected to the end of the liquid outlet pipe 11 via a universal joint, and the universal joint is equipped with an angle locking bolt. The universal joint consists of two connectors connected by mutually perpendicular rotating shafts. One connector is threaded to the end of the liquid outlet pipe 11, and the other connector is connected to the spray head 12. Each rotating shaft is equipped with a butterfly or knob-type angle locking bolt, the end of which abuts against the rotating shaft, using friction to achieve fixation. This allows for unlimited and flexible adjustment of the spray angle. Users can precisely adjust the spray angle according to the height, density, and wind direction of the wheat to ensure that the pesticide solution can most effectively cover the target canopy. After adjustment, tightening the locking bolt securely fixes the spray head.

[0036] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
