一般挖斗的鏈式挖沟机,其生产率的提高受到一定的限制。因为当增加挖斗运动速度或挖斗数目时,土壤可能从一个斗落入另一斗中。装一般挖斗时,由于挖斗与挖斗的中間不能装填土壤,所以不可能形成連續的土流,因此不可能提高机器的生产率。为了研究不增加机器重量和发动机的功率,而能进一步提高鏈式挖沟机的生产率, In the case of chain trenchers, which are generally used for buckets, their productivity has been limited. Because when you increase the speed of the bucket or the number of buckets, the soil may fall from one bucket into another bucket. When a general bucket is installed, since the soil between the bucket and the bucket cannot be filled with soil, it is impossible to form a continuous earth flow, so it is impossible to increase the productivity of the machine. In order to further increase the productivity of chain-type trenchers without increasing the weight of the machine and the power of the engine,
