耙头

新型主动耙头的开发和应用

A new type of active drag head

强力混合机叶轮轴上耙头及叶片安装角度的改进

Improving the installing angles of harrow and blade in intensive mixer

详细讨论了主要作用力：在波浪补偿器作用下的缆绳拉力、耙头与海床间的土壤剪切力、作用在耙吸管上的水流阻力及由于压力差在耙头处产生的推动力等。

The tension force , shear forces ( including pushing force , cutting force and friction force ), impulse force , hydrodynamic drag on the suction pipes , and the force resulted from the pressure difference , etc , are the main forces for detail discussion in this paper .
