The working principle of the steel plate plow is primarily based on the three-sided wedge principle. During operation, the plowshare first cuts into the soil, severing soil chunks. Subsequently, these soil chunks are crushed and turned over along the moldboard, covering any residual stubble or weeds below the furrow. In this way, the plow accomplishes soil cutting, crushing, turning, and weed covering, preparing the ground for subsequent operations such as planting. The structure of the plow comprises the plowshare, moldboard, side plates, brackets, and columns, which work together to complete the tillage operations. The plowshare and moldboard form the working surface of the plow body, known as the plow body surface, which is crucial for penetrating the soil, cutting, crushing, and turning over soil chunks.
