[0005] Backpack equipment relies on manual operation, with high labor intensity, low efficiency, and uneven spray coverage, making it difficult to meet the needs of large-scale greenhouse cultivation. In addition, traditional equipment has poor atomization effect, low utilization rate of liquid medicine, easy to cause waste of liquid medicine and environmental pollution, and lacks intelligent control, unable to monitor and adjust spray parameters in real time, and difficult to adapt to the development trend of modern precision agriculture.

[0036] Liquid medicine tank 2, with a medicine addition port at the upper part and a water supply pipe interface and a liquid medicine pipe interface at the bottom;

[0037] Filtering device 3, including a secondary filter 31, a water inlet pipe 32, and a water supply pipe 33, used to filter and convey water source to the liquid medicine tank 2. One end of the water inlet pipe 32 is connected to the water inlet of the filter 31, and one end of the water supply pipe 33 is connected to the water outlet of the filter 31, and the other end is connected to the water supply pipe interface of the liquid medicine tank 2 to supply the filtered water into the liquid medicine tank 2. Inside the liquid medicine tank 2, a liquid level sensor and a stirring device are provided. The controller 8 automatically controls medicine addition or shutdown according to the liquid level data;

[0038] Pressurizing device 4, including a booster pump 41, a pressure regulator 42, a pressure gauge 43, a liquid medicine pipe 44, a liquid outlet pipe 45, and a liquid outlet pipe joint 451, used to pressurize the liquid medicine and convey it to the spraying system 6. The booster pump 41 is installed at the bottom of the chassis 1, and a pressure gauge 43 is also provided on the booster pump 41 to indicate the pressure of spraying. The pressure regulator 42 of the pressurizing device 4 is electrically connected to the controller 8 to adjust the pressure of spraying. One end of the liquid medicine pipe 44 is connected to the interface at the bottom of the liquid medicine tank 2, and the other end is connected to the liquid outlet of the booster pump 41. One end of the liquid outlet pipe 45 is connected with a liquid outlet pipe joint 451. The liquid outlet pipe joint 451 adopts a magnetic adsorption type or quick-release type sealing structure, which is convenient for quickly connecting with the spraying systems 6 of different greenhouses;

[0039] Traveling system 5, including four driving motors 51 and traveling wheels 52, which are respectively installed at the bottom of the chassis 1 to drive the driving wheels to travel. The driving motors are electrically connected to the controller 8 and start and stop according to the instructions of the controller 8. The traveling wheels are pneumatic rubber wheels, connected to the driving motors, used for traveling and supporting the weight of the machine; Through multi-sensor fusion technology, the controller 8 can combine environmental sensor data to realize the automatic navigation of the traveling system 5, automatically plan the path according to the preset path or the actual situation of the greenhouse, reduce manual intervention, and improve the operation efficiency.

[0040] Spraying system 6, including a connecting pipe 61, a spraying pipe 62, and a high-efficiency atomizing nozzle 63. The spraying system 6 is fixedly installed in the greenhouse. The connecting pipe 61 is detachably connected to the liquid outlet pipe joint 451. The spraying pipe 62 of the spraying system 6 is provided with a height adjustment mechanism, and the atomizing angle of the nozzle 63 is adjustable. There are several nozzle connection holes on the pipe wall of the spraying pipe 62 to atomize the pressurized liquid medicine and spray it into the greenhouse interior;

[0041] The spray monitoring device 7 is used to monitor the spray quality in real time and feedback it to the controller 8; together with the controller 8, the pressurizing device 4, the traveling system 5, etc., it constitutes an intelligent closed-loop control system to ensure the accuracy and efficiency of the spraying operation.

[0042] The controller 8 is used to control the traveling system 5, the pressurizing device 4, and the spray system 6, and dynamically adjust the spray parameters according to the monitoring data. Relying on the multi-sensor fusion technology, it comprehensively processes multi-source data such as the liquid level sensor and the spray monitoring device 7 to achieve intelligent control of the entire spraying operation process.

[0043] First, push the mobile sprayer to the greenhouse operation area to ensure that the pneumatic tire 52 of the traveling system 5 is firmly grounded. Open the medicine adding port of the medicine tank 2, inject the required medicine and water, and the liquid level sensor monitors the liquid level height in real time. The controller 8 automatically controls the operation of the stirring device according to the data to make the medicine liquid evenly mixed. At the same time, connect the external water source to the water inlet pipe 32 of the filtering device 3. After the secondary filter 31 purifies the water, clear water is supplied to the medicine tank 2 through the water supply pipe 33 to ensure the stability of the medicine liquid concentration.

[0044] Quickly dock the connecting pipe 61 of the spray system 6 with the liquid outlet pipe joint 451 of the pressurizing device 4. The magnetic attraction or quick-release structure ensures the sealing performance. Set the spray parameters through the controller 8, including the pressure of the booster pump 41 adjusted by the pressure regulator 42, the height of the spray pipe 62 adjusted by the lifting mechanism, and the atomization angle of the nozzle 63. The drive motor 51 of the traveling system 5 receives the controller command and starts to move along the preset path. At the same time, the booster pump 41 is started, and the medicine liquid is transported to the spray system 6 through the medicine liquid pipe 44 and the liquid outlet pipe 45. The atomizing nozzle 63 evenly sprays the medicine liquid onto the crops. During this process, the multi-sensor fusion technology plays a role. The controller 8 perceives the environmental changes and the equipment operation status in real time and dynamically optimizes the spray parameters; the automatic navigation function enables the traveling system 5 to accurately complete the operation path planning without too much manual operation.

[0045] The spray monitoring device 7 detects the atomization effect and coverage rate in real time and feeds the data back to the controller 8. If the spray pressure is insufficient or the atomization is uneven, the controller automatically adjusts the pressure of the booster pump 41 or pauses the traveling system 5 for calibration. After the operation is completed, the controller 8 stops the pressurizing device 4 and the traveling system 5, disconnects the connecting pipe 61 of the spray system 6, empties the medicine tank 2 and cleans the pipeline for the next use. Throughout the process, the intelligent control system ensures accurate and efficient pesticide application, adapts to the needs of different greenhouse environments, and fully demonstrates the innovative advantages such as cost reduction through multi-greenhouse sharing, accuracy improvement through dynamic parameter optimization, and reduction of manual intervention through automatic navigation.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
