螺旋切削式采集头的结构参数和工作参数,尤其是切削深度,直接影响到采集头的力学特性和切削产物的粒度分布规律．通过建立的相似试验台进行了一系列的试验,研究了不同切削深度对截齿截割力、采集头扭矩、功率、比能耗、波动性及粒度分布的影响．相似试验结果表明,当切削深度在30 mm以内时,截齿平均力为160～300 N、采集头平均力矩为400～1100 N·m;比能耗为3～9 kWh/t;截齿力的波动系数为3～4．5、力矩的波动系数0．6～1．2;钴结壳模拟料破碎粒度的粒径都小于50 mm,证明现有结构的模型采集头能够满足钴结壳开采的需要．图7,参9．
The structural parameters and working parameters of helical cutting head, especially the cutting depth, have a direct impact on the mechanical characteristics of the head and the particle size distribution of the cutting products. A series of experiments were carried out on similar test rigs established. The effects of different cutting depths on cutting force, head torque, power, specific energy consumption, volatility and particle size distribution were studied. The results of similar tests show that when the depth of cut is within 30 mm, the average force of the picks is 160-300 N, the average torque of the collecting head is 400-1100 N · m, and the specific energy consumption is 3-9 kWh / t. , The fluctuation coefficient of torque is 3 ~ 4.5, and the fluctuation coefficient of torque is 0.6 ~ 1.2. The particle size of the crushed particle size of the cobalt crust are less than 50 mm, which proves that the model acquisition head of the existing structure can satisfy the cobalt crust The need for mining.
