Plow blades are mainly classified into two types based on their structure: straight plow blades and round plow blades. Straight plow blades are simple in structure, sturdy and durable, but offer greater working resistance. Round plow blades roll and cut the soil during operation, resulting in less resistance and less entanglement with weeds.
Round plow blades can be further subdivided based on the shape of the blade head and the cutting edge. According to the blade head type, they can be divided into ordinary blade heads, notched blade heads, and corrugated blade heads. Based on the cutting edge shape, they can be further classified into flat, notched, and grooved types. Among them, the grooved round plow blade has a toothed groove on its cutting edge; after a period of use, as the groove gradually wears down, the cutting edge changes.
In corrugated plow blades, as the number of corrugations increases, the cutting resistance, furrow width, and groove area gradually decrease, while the slippage rate and residue disturbance rate gradually increase.
