The invention discloses an electric screw leveling device, which is characterized by taking a universal joint as the support, limiting the freedom of the platform up and down and rotating, and adjusting the spatial angle of the platform by adjusting the length of the four electric screws. The invention takes a small crawler tractor as an example, and uses a servo motor as a power source. The regulated platform is connected to the chassis through a universal joint. Four electric cylinders are installed in the four comers of the regulated platform, and are connected to the regulated platform through a joint bearing. Four electric poles are linked. The length of four electric poles determines the inclination angle of the regulated platform. Therefore, the inclination angle of the regulated platform is adjusted by changing the length of four electric poles. The invention is specially designed for small-sized agricultural power machines and tools, has small occupied space, low energy consumption and light weight, and well solves the problem that the small-sized agricultural machinery operation platform inclines due to uneven land, which enhances the stability and safety of tractors in hilly and mountainous areas when walking.
