Dredge cutter head design

 Here are some guidelines for planning dredger reamers:
  (1) The outer contour of the reamer cutting soil and the enclosing angle of the knife arm are more and more reasonable according to different soil quality and working conditions.
(2) The rotation angle of each tooth position is closer to the theoretical orientation.
(3) The optimal positioning of the cutting angles of the teeth of each tooth of the reamer depends more and more on the experiments of the cutting model and the practical model.
(4) The reamer arm planning takes into account the material transport performance and water conservancy performance together with the maximum limit to improve the reamer free cutting interval and reduce the reamer cutting energy ratio.
(5) Reduce tooth replacement times by increasing the wear resistance of the teeth to ensure the service life of the tooth holders.
