[0002] A boom stabilization and self-balancing device for a self-propelled boom sprayer is an auxiliary device used for automatic adjustment and balance of the boom, and it has been widely used in the field of self-balancing devices. Currently, due to technical and cost control reasons, most of the booms installed on existing self-propelled boom sprayers are directly connected and assembled with the frame without an independent automatic boom balancing device. Therefore, when the field is not level, the frame will sway with the undulations of the field. Affected by this, the boom will also sway with the frame, which can easily cause the boom to tilt and sway, scratching crops or even damaging the boom. Although some self-propelled boom sprayers are equipped with automatic boom balancing systems.
