In this paper, we design a farm machine integrating the functions of chopping field straw, pressing field straw into soil, breaking stubble, and cleaning up plastic film, in order to improve the efficiency of plastic film cleaning, enrich the function of straw chopping equipment, reduce the noise generated at work, and further realize the intelligent harmony. The remote control button is used to control the work of the entire system, and the bluetooth remote control module and matrix keyboard are used to control the vehicle. With STM32 microcontroller as the main control chip, the machine controls the motion of the electric motor by relay, and employs LCD screen to realize real-time display of system work. It is convenient and easy to operate, with good human-computer interaction.
