Description

Technical Field

[0001] The invention relates to the technical field of plant protection equipment, in particular to a multifunctional self-propelled plant protection machine. Background Art

[0002] The multifunctional self-propelled plant protection machine is a modern agricultural machinery, mainly used for plant protection operations of field crops, including spraying pesticides, fertilizers, plant growth regulators, etc. This kind of machinery has a high degree of automation and versatility, which can improve operation efficiency, reduce labor costs, and improve the accuracy of plant protection operations;

[0003] In the process of fertilizing, the multifunctional self-propelled plant protection machine usually spreads the fertilizer evenly on the surface of the soil first, and then drives the loosening wheel to rotate. When the loosening wheel passes through the soil sprinkled with pesticides, the loosening wheel will plow the land, which helps to bury the fertilizer. In the process of spraying pesticides, the multifunctional self-propelled plant protection machine usually uses the atomizing nozzle to atomize and spray the pesticides, and then uses the wind generated by the fan to blow the atomized pesticides to the crops;

[0004] During the use of the existing multifunctional self-propelled plant protection machine, although the soil can be tilled by the loosening wheel, when encountering some relatively hard soil, in order to ensure the tillage effect, the multifunctional self-propelled plant protection machine needs to repeatedly till the area, thereby reducing the work efficiency. In the process of spraying pesticides, since the positions of most spraying components are fixed, this will result in limited coverage of pesticide spraying, and it is difficult to adapt to different crop layouts and row spacings, reducing the adaptability and flexibility of the multifunctional self-propelled plant protection machine. When the multifunctional self-propelled plant protection machine needs to turn during movement, the steering angle of the guide wheel is usually adjusted by the adjustment device to achieve a smooth turning action. However, after the adjustment, the guide wheel is usually locked and fixed by the driving component using a locking pin. Since the locking pin is relatively small in size or thin in thickness, it is often deformed due to the influence of external force, which finally affects the stability of the guide wheel. For this reason, we propose a multifunctional self-propelled plant protection machine. Summary of the invention
