The invention discloses a self-adaptive vehicle body leveling and electro-hydraulic suspension device for agricultural machinery slope operation, relates to the technical field of agricultural machinery vehicle body systems and suspension systems, and aims to solve the problem that an existing agricultural machinery vehicle body device and an existing suspension device cannot be self-adaptively adjusted according to a slope environment. Comprising a chassis, front wheels, rear wheels, a front axle, a rear axle, a suspension unit and a sloping field detection assembly, the front axle comprises an upper swing arm, two lower swing arms and two wheel carriers, and the wheel carriers, the lower swing arms, the chassis and the upper swing arm form a parallelogram connecting rod mechanism; the suspension unit comprises a suspension rack, a lifting arm assembly, a left pull rod and a right pull rod; the sloping field detection assembly comprises a vehicle body tilt angle sensor fixed to the upper swing arm and a farm tool tilt angle sensor fixed to the operation machine tool. The inclination angle of the upper swing arm is detected, the adjusting oil cylinder I and the adjusting oil cylinder II are started according to the inclination angle of the upper swing arm, and the inclination angle of the operation machine tool is adjusted, so that the operation machine tool adapts to the slope environment, and the operation quality is guaranteed.
