[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be considered as limiting the scope of the claims.

[0041] Working principle:

[0042] The cartridge case is stably mounted on the L-shaped trolley frame and base plate via a triple structure of mechanical limiting, screw connection, and guide rail insertion. The arc-shaped groove of the fixing frame conforms to the shape of the cartridge case to form an initial limiting, and long bolts are screwed to the outer wall of the cartridge case for further locking. At the same time, the guide rail groove of the cartridge case is inserted into the guide rail of the trolley frame to prevent displacement during pushing. The anti-slip texture on the surface of the base plate also helps to prevent the cartridge case from sliding, and the triangular reinforcing ribs at the L-shaped connection improve the overall structural stability and cope with vibrations under complex road conditions.

[0043] The device is designed with two application modes to adapt to different farmland scenarios. When operating in open areas, the spray cartridge is fixed to the cart and moved by the casters on both sides of the base plate, reducing the burden of manual handling. When encountering narrow field ridges, dense crop areas, or other scenarios where the cart cannot pass, the fixing bolts can be removed and the cartridge can be detached from the guide rail. The high-strength nylon shoulder strap on the cartridge can be used to carry the cartridge on your back, and the embedded stainless steel buckle ensures the safety of bearing weight when carrying it.

[0044] The cartridge, as the core storage component, is used to inject pesticides through the filling port at the top. The sealing cap of the filling port can prevent pesticide leakage or evaporation, and at the same time prevent farmland debris from entering the cartridge and contaminating the pesticides.

[0045] A lithium-ion battery-powered booster pump provides power for pesticide delivery, with an adjustable operating pressure ranging from 0.3 to 0.8 MPa, allowing for different spray intensities. The booster pump pressurizes the pesticide in the cartridge and delivers it to the applicator via a connecting pipe, meeting the needs of long-distance or high-intensity spraying. The 12Ah capacity of the lithium battery ensures 4 hours of continuous use, while fast charging and a power display enhance ease of use. A shock-absorbing bracket reduces pump vibration and noise during operation, extending equipment lifespan.

[0046] The sprayer extends the spraying range through the spraying rod. The operator holds the handle at the end and uses the control switch on the handle to start and stop the spraying and adjust the power, so as to accurately control the timing and intensity of the spraying.

[0047] The spraying plate at the other end of the spraying rod is connected via a damping swivel shaft, allowing for 90-degree rotation adjustment to suit the row spacing, height, and other requirements of different crops. The evenly distributed atomizing nozzles on the spraying plate convert the pesticide into a mist, expanding the spraying area per application, improving work efficiency, and ensuring the pesticide adheres evenly to the crop surface, thus enhancing the spraying effect while reducing manual labor intensity.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
