Classification of slings

  Swing blade also known as the orange scale returned to the field blade, kaiyuan blade. If the stalk returning to field blade is the main working part of the machine, its shape and parameters have great influence on the working quality and power consumption of the machine. In order to meet the needs of pulverizing all kinds of crop straw, many kinds of blades have been developed in China in recent years, which can be generally classified into the following categories:

  1.Hammer claw blade

  This type of blade is made of high strength wear-resistant cast steel,which is characterized by high strength and wear resistance.The disadvantage is that it consumes more power,so in some places where the transverse checks are relatively dense and high not quite.

  2.External swinging knife blade

  3.Straight blade

  This type of blade is welded by several straight blades,one transverse blade and the sleeve,the blade is made of high manganese steel,the advantages are better crushing effect,the disadvantages are higher cutting stubble,the manufacturing process is more complex.
