Introduction of rotary tiller using اعلي تعدد سخت ڪرڻ واري مشين گرمي جي علاج لاء

The rotary cultivator is the main component of the rotary cultivator. When it advances with the tractor, the horizontal knife shaft rotates, and the multiple rotary cultivators installed on the knife shaft continuously plow the farmland while rolling forward, breaking the soil ridges and cutting off residues. Stubble and throw the soil back. It is widely used in rice, vegetable cultivation and plastic greenhouses. The rotary tiller can be designed in different shapes. The mouth is worn by sand and gravel in the soil, and the handle and blade are bent or broken by the impact of rocks and tree roots in the soil, so the failure modes are wear, bending and breaking. Therefore, it is required that the rotary cutter in the high frequency hardening machine has high hardness and wear resistance, and at the same time has a certain strength and toughness. It is usually made of 65Mn, T9 steel, etc., the hardness after heat treatment is 48-54HRC, and the handle is 38-45HRC. Paddy paddy blades are also important tools, mainly used for farming in southern paddy fields.
