The invention provides a pesticide sprayer with balance control function, and relates to the technical field of agricultural equipment. The pesticide sprayer with the balance control function comprises an interconnection suspension system and a vehicle, wherein the interconnection suspension system comprises hydraulic jacks, a first steering gear, a second steering gear, a fluid pump and a fluid source; two hydraulic jacks are arranged at the upper side of each wheel; the lower parts of two hydraulic jacks positioned on different wheels at the same end are connected through a first pipeline, and the upper parts are connected through a second pipeline; the lower parts of the rest hydraulic jacks positioned on different wheels at the same end are correspondingly connected with the lower parts of the rest hydraulic jacks on different wheels at the other one of the ends at the same side through third pipelines, and the upper parts are connected through a fourth pipeline; the first pipeline is connected with the first pipeline at the opposite side through a pipeline, and the third pipeline is connected with the third pipeline at the opposite side through the pipeline. According to the pesticide sprayer with the balance control function, the vehicle can be prevented from greatly bumping while running on an uneven ground; the responding sensitivity is high; the stability and the comfortability are high; the side inclining resistance, the side overturning resistance and the pitching resistance are provided, so that the climbing capacity is high.
