Disc harrow absorbs the advantages of similar foreign advanced products, according to the standard design, the whole machine adopts modular structure, the overall rigid harrow as the main body, equipped with hydraulic landing gear, spring leveling mechanism and disk harrow dedicated Spherical ball bearings within the spherical spherical bearing, disc harrow with a reasonable structure, durable, easy transport, small radius of rotation, easy to adjust, maintenance and so on. Harrow blade is the main core of the disc harrow, an important factor in the level of disc harrows, we will look at it below:
Uneven hardness Depositing, the disk harrow by ten welding layer thickness unevenness may cause uneven hardness . Hard coating area is usually ten carbon carburizing, that is , the operator of the oxygen-acetylene flame flame core into the molten cladding or the inner flame of the flame than the length of the big 3: 1 caused. The area where the hardness of the cladding layer is lower is usually the result of the incorporation of the ten matrix metal into the cladding layer .
Crack. Low preheating temperature before welding, poor welding process control ( temperature drop too fast ) and rapid cooling after welding. Are easy to make the weld layer cracks. Therefore, preheating and cooling before welding is a nickel-based hard alloy oxy-acetylene flame welding is an important feature. In addition disc harrow operation diagram, the quenched parts without annealing are also prone to cracks. If the weld crack has spread into the base metal, the wheel needs to be cleaned of the crack ( or removed by other machining methods). According to the provisions of the preheating process, welding, slow cooling. If the crack does not spread to the base metal, the part can be reheated to eliminate cracks .
